------------------
From: Miaoqian Lin <linmq006@gmail.com>
commit dc89548c6926d68dfdda11bebc1a5258bc41d887 upstream.
The code did not check the return value of usbnet_get_endpoints.
Add checks and return the error if it fails to transfer the error.
Found via static anlaysis and this is similar to
commit 07161b2416f7 ("sr9800: Add check for usbnet_get_endpoints").

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quanmin Yan <yanquanmin1@huawei.com>
commit a1f3058930745d2b938b6b4f5bd9630dc74b26b7 upstream.
Recently, we discovered the following issue through syzkaller:
BUG: KASAN: slab-use-after-free in fb_mode_is_equal+0x285/0x2f0
Read of size 4 at addr ff11000001b3c69c by task syz.xxx
...
Call Trace:

entry_SYSCALL_64_after_hwframe+0x76/0x7e
Based on experimentation and analysis, during framebuffer unregistration,
only the memory of fb_info->modelist is freed, without setting the
corresponding fb_display[i]->mode to NULL for the freed modes. This leads
to UAF issues during subsequent accesses. Here's an example of reproduction
steps:
1. With /dev/fb0 already registered in the system, load a kernel module
to register a new device /dev/fb1;
2. Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);
3. Switch console from fb to VGA (to allow normal rmmod of the ko);
4. Unload the kernel module, at this point fb1's modelist is freed, leaving
a wild pointer in fb_display[];
5. Trigger the bug via system calls through fb0 attempting to delete a mode
from fb0.
Add a check in do_unregister_framebuffer(): if the mode to be freed exists
in fb_display[], set the corresponding mode pointer to NULL.

commit 7073c7fc8d8ba47194e5fc58fcafc0efe7586e9b upstream.
Actually check the return value from pll_ops->init_pll()
as it can return an error.
If the card's BIOS didn't run because it's not the primary VGA card
the fact that the xclk source is unsupported is printed as shown
below but the driver continues on regardless and on my machine causes
a hard lock up.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuhao Jiang <danisjiang@gmail.com>
commit 8f067aa59430266386b83c18b983ca583faa6a11 upstream.
The switch_brightness_work delayed work accesses device->brightness
and device->backlight, freed by acpi_video_dev_unregister_backlight()
during device removal.
If the work executes after acpi_video_bus_unregister_backlight()
frees these resources, it causes a use-after-free when
acpi_video_switch_brightness() dereferences device->brightness or
device->backlight.
Fix this by calling cancel_delayed_work_sync() for each device's
switch_brightness_work in acpi_video_bus_remove_notify_handler()
after removing the notify handler that queues the work. This ensures
the work completes before the memory is freed.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bui Quang Minh <minhquangbui99@gmail.com>
commit 1ab665817448c31f4758dce43c455bd4c5e460aa upstream.
In virtio-net, we have not yet supported multi-buffer XDP packet in
zerocopy mode when there is a binding XDP program. However, in that
case, when receiving multi-buffer XDP packet, we skip the XDP program
and return XDP_PASS. As a result, the packet is passed to normal network
stack which is an incorrect behavior (e.g. a XDP program for packet
count is installed, multi-buffer XDP packet arrives and does go through
XDP program. As a result, the packet count does not increase but the
packet is still received from network stack).This commit instead returns
XDP_ABORTED in that case.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junjie Cao <junjie.cao@intel.com>
commit 18c4ef4e765a798b47980555ed665d78b71aeadf upstream.
bit_putcs_aligned()/unaligned() derived the glyph pointer from the
character value masked by 0xff/0x1ff, which may exceed the actual font's
glyph count and read past the end of the built-in font array.
Clamp the index to the actual glyph count before computing the address.
This fixes a global out-of-bounds read reported by syzbot.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 91d35ec9b3956d6b3cf789c1593467e58855b03a upstream.
The RFCOMM driver confuses the local and remote modem control signals,
which specifically means that the reported DTR and RTS state will
instead reflect the remote end (i.e. DSR and CTS).
This issue dates back to the original driver (and a follow-on update)
merged in 2002, which resulted in a non-standard implementation of
TIOCMSET that allowed controlling also the TS07.10 IC and DV signals by
mapping them to the RI and DCD input flags, while TIOCMGET failed to
return the actual state of DTR and RTS.
Note that the bogus control of input signals in tiocmset() is just
dead code as those flags will have been masked out by the tty layer
since 2003.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gokul Sivakumar <gokulkumar.sivakumar@infineon.com>
commit 3776c685ebe5f43e9060af06872661de55e80b9a upstream.
Currently, whenever there is a need to transmit an Action frame,
the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to
firmware. The P2P interfaces were available when wpa_supplicant is managing
the wlan interface.
However, the P2P interfaces are not created/initialized when only hostapd
is managing the wlan interface. And if hostapd receives an ANQP Query REQ
Action frame even from an un-associated STA, the brcmfmac driver tries
to use an uninitialized P2P vif pointer for sending the IOVAR to firmware.
This NULL pointer dereferencing triggers a driver crash.

Fix this, by always using the vif corresponding to the wdev on which the
Action frame Transmission request was initiated by the userspace. This way,
even if P2P vif is not available, the IOVAR is sent to firmware on AP vif
and the ANQP Query RESP Action frame is transmitted without crashing the
driver.
Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev()
to brcmf_p2p_attach(). Because the former function would not get executed
when only hostapd is managing wlan interface, and it is not safe to do
reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior
init_completion().
And in the brcmf_p2p_tx_action_frame() function, the condition check for
P2P Presence response frame is not needed, since the wpa_supplicant is
properly sending the P2P Presense Response frame on the P2P-GO vif instead
of the P2P-Device vif.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fuchs <fuchsfl@gmail.com>
commit 5f566c0ac51cd2474e47da68dbe719d3acf7d999 upstream.
Commit e24cca19babe ("sh: Kill off MAX_DMA_ADDRESS leftovers.") removed
the define ONCHIP_NR_DMA_CHANNELS. So that the leftover reference needs
to be replaced by CONFIG_NR_ONCHIP_DMA_CHANNELS to compile successfully
with CONFIG_PVR2_DMA enabled.

------------------
From: Miaoqian Lin <linmq006@gmail.com>
commit eb53368f8d6e2dfba84c8a94d245719bcf9ae270 upstream.
The of_find_node_by_name() function returns a device tree node with its
reference count incremented. The caller is responsible for calling
of_node_put() to release this reference when done.
Found via static analysis.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@redhat.com>
commit 27b0e701d3872ba59c5b579a9e8a02ea49ad3d3b upstream.
Accessing the transmit queue without owning the msk socket lock is
inherently racy, hence __mptcp_check_push() could actually quit early
even when there is pending data.
That in turn could cause unexpected tx lock and timeout.
Dropping the early check avoids the race, implicitly relaying on later
tests under the relevant lock. With such change, all the other
mptcp_send_head() call sites are now under the msk socket lock and we
can additionally drop the now unneeded annotation on the transmit head
pointer accesses.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@redhat.com>
commit a824084b98d8a1dbd6e85d0842a8eb5e73467f59 upstream.
Since commit 72377ab2d671 ("mptcp: more conservative check for zero
probes") the MPTCP-level zero window probe check is always disabled, as
the TCP-level write queue always contains at least the newly allocated
skb.
Refine the relevant check tacking in account that the above condition
and that such skb can have zero length.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Farhan Ali <alifm@linux.ibm.com>
commit b45873c3f09153d1ad9b3a7bf9e5c0b0387fd2ea upstream.
Commit c1e18c17bda6 ("s390/pci: add zpci_set_irq()/zpci_clear_irq()"),
introduced the zpci_set_irq() and zpci_clear_irq(), to be used while
resetting a zPCI device.
Commit da995d538d3a ("s390/pci: implement reset_slot for hotplug
slot"), mentions zpci_clear_irq() being called in the path for
zpci_hot_reset_device(). But that is not the case anymore and these
functions are not called outside of this file. Instead
zpci_hot_reset_device() relies on zpci_disable_device() also clearing
the IRQs, but misses to reset the zdev->irqs_registered flag.
However after a CLP disable/enable reset, the device's IRQ are
unregistered, but the flag zdev->irq_registered does not get cleared. It
creates an inconsistent state and so arch_restore_msi_irqs() doesn't
correctly restore the device's IRQ. This becomes a problem when a PCI
driver tries to restore the state of the device through
pci_restore_state(). Restore IRQ unconditionally for the device and remove
the irq_registered flag as its redundant.

6.12-stable review patch. If anyone has any objections, please let me know.

From: Henrique Carvalho <henrique.carvalho@suse.com>
commit 5c76f9961c170552c1d07c830b5e145475151600 upstream.
When smb2_query_info_compound() retries, a previously allocated cfid may
have been freed in the first attempt.
Because cfid wasn't reset on replay, later cleanup could act on a stale
pointer, leading to a potential use-after-free.
Reinitialize cfid to NULL under the replay label.
Example trace (trimmed):
refcount_t: underflow; use-after-free.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chang S. Bae <chang.seok.bae@intel.com>
commit 388eff894d6bc5f921e9bfff0e4b0ab2684a96e9 upstream.
Sean reported [1] the following splat when running KVM tests:
WARNING: CPU: 232 PID: 15391 at xfd_validate_state+0x65/0x70
Call Trace:
<TASK>
fpu__clear_user_states+0x9c/0x100

do_syscall_64+0x205/0x2c0
entry_SYSCALL_64_after_hwframe+0x4b/0x53
Chao further identified [2] a reproducible scenario involving signal
delivery: a non-AMX task is preempted by an AMX-enabled task which
modifies the XFD MSR.
When the non-AMX task resumes and reloads XSTATE with init values,
a warning is triggered due to a mismatch between fpstate::xfd and the
CPU's current XFD state. fpu__clear_user_states() does not currently
re-synchronize the XFD state after such preemption.
Invoke xfd_update_state() which detects and corrects the mismatch if
there is a dynamic feature.
This also benefits the sigreturn path, as fpu__restore_sig() may call
fpu__clear_user_states() when the sigframe is inaccessible.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Loic Poulain <loic.poulain@oss.qualcomm.com>
[ Upstream commit 2e9c1da4ee9d0acfca2e0a3d78f3d8cb5802da1b ]
ath10k_wmi_cmd_send takes ownership of the passed buffer (skb) and has the
responsibility to release it in case of error. This patch fixes missing
free in case of early error due to unhandled WMI command ID.
Tested-on: WCN3990 hw1.0 WLAN.HL.3.3.7.c2-00931-QCAHLSWMTPLZ-1

From: Mark Pearson <mpearson-lenovo@squebb.ca>
[ Upstream commit 0eb002c93c3b47f88244cecb1e356eaeab61a6bf ]
Lenovo platforms can come with one of two different IDs.
The pm_quirk table was missing the second ID for each platform.
Add missing ID and some extra platform identification comments.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Karthik M <quic_karm@quicinc.com>
[ Upstream commit 92282074e1d2e7b6da5c05fe38a7cc974187fe14 ]
ath12k just like ath11k [1] did not handle skb cleanup during idr
cleanup callback. Both ath12k_mac_vif_txmgmt_idr_remove() and
ath12k_mac_tx_mgmt_pending_free() performed idr cleanup and DMA
unmapping for skb but only ath12k_mac_tx_mgmt_pending_free() freed
skb. As a result, during vdev deletion a memory leak occurs.
Refactor all clean up steps into a new function. New function
ath12k_mac_tx_mgmt_free() creates a centralized area where idr
cleanup, DMA unmapping for skb and freeing skb is performed. Utilize
skb pointer given by idr_remove(), instead of passed as a function
argument because IDR will be protected by locking. This will prevent
concurrent modification of the same IDR.
Now ath12k_mac_tx_mgmt_pending_free() and
ath12k_mac_vif_txmgmt_idr_remove() call ath12k_mac_tx_mgmt_free().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yu Zhang(Yuriy) <quic_yuzha@quicinc.com>
[ Upstream commit b78c02f7c7104f1e77ade12ebde267e6fb388ca9 ]
The current code does not have the MU EDCA feature, so it cannot support
the use of EDCA by STA in specific UL MU HE TB PPDU transmissions. Refer
to IEEE Std 802.11ax-2021 "9.4.2.251 MU EDCA Parameter Set element",
"26.2.7 EDCA operation using MU EDCA parameters".
Add ath11k_mac_op_conf_tx_mu_edca() to construct the MU EDCA parameters
received from mac80211 into WMI WMM parameters，and send to the firmware
according to the different WMM type flags.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rameshkumar Sundaram <rameshkumar.sundaram@oss.qualcomm.com>
[ Upstream commit 9c78e747dd4fee6c36fcc926212e20032055cf9d ]
Bitwise operations with WMI_KEY_PAIRWISE (defined as 0) are ineffective
and misleading. This results in pairwise key validations added in
commit 97acb0259cc9 ("wifi: ath11k: fix group data packet drops
during rekey") to always evaluate false and clear key commands for
pairwise keys are not honored.
Since firmware supports overwriting the new key without explicitly
clearing the previous one, there is no visible impact currently.
However, to restore consistency with the previous behavior and improve
clarity, replace bitwise operations with direct assignments and
comparisons for key flags.

From: Akhil P Oommen <akhilpo@oss.qualcomm.com>
[ Upstream commit b4789aac9d3441d9f830f0a4022d8dc122d6cab3 ]
Current parser logic for GMU firmware assumes a dword aligned payload
size for every block. This is not true for all GMU firmwares. So, fix
this by using correct 'size' value in the calculation for the offset
for the next block's header.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Schmaus <florian.schmaus@codasip.com>
[ Upstream commit 2551a1eedc09f5a86f94b038dc1bb16855c256f1 ]
The previous implementation incorrectly assumed the original type of
'priv' was void**, leading to an unnecessary and misleading
cast. Correct the cast of the 'priv' pointer in test_dev_action() to
its actual type, long*, removing an unnecessary cast.
As an additional benefit, this fixes an out-of-bounds CHERI fault on
hardware with architectural capabilities. The original implementation
tried to store a capability-sized pointer using the priv
pointer. However, the priv pointer's capability only granted access to
the memory region of its original long type, leading to a bounds
violation since the size of a long is smaller than the size of a
capability. This change ensures that the pointer usage respects the
capabilities' bounds.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Noorain Eqbal <nooraineqbal@gmail.com>
[ Upstream commit 4e9077638301816a7d73fa1e1b4c1db4a7e3b59c ]
Fix a race where irq_work can be queued in bpf_ringbuf_commit()
but the ring buffer is freed before the work executes.
In the syzbot reproducer, a BPF program attached to sched_switch
triggers bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer
is freed before this work executes, the irq_work thread may accesses
freed memory.
Calling `irq_work_sync(&rb->work)` ensures that all pending irq_work
complete before freeing the buffer.
Fixes: 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it")

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit a76ab5731e32d50ff5b1ae97e9dc4b23f41c23f5 ]
Private stack will be allocated with percpu allocator in jit time.
To avoid complexity at runtime, only one copy of private stack is
available per cpu per prog. So runtime recursion check is necessary
to avoid stack corruption.
Current private stack only supports kprobe/perf_event/tp/raw_tp
which has recursion check in the kernel, and prog types that use
bpf trampoline recursion check. For trampoline related prog types,
currently only tracing progs have recursion checking.
To avoid complexity, all async_cb subprogs use normal kernel stack
including those subprogs used by both main prog subtree and async_cb
subtree. Any prog having tail call also uses kernel stack.
To avoid jit penalty with private stack support, a subprog stack
size threshold is set such that only if the stack size is no less
than the threshold, private stack is supported. The current threshold
is 64 bytes. This avoids jit penality if the stack usage is small.
A useless 'continue' is also removed from a loop in func
check_max_stack_depth().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ondrej Mosnacek <omosnace@redhat.com>
[ Upstream commit 881a9c9cb7856b24e390fad9f59acfd73b98b3b2 ]
The failure of this check only results in a security mitigation being
applied, slightly affecting performance of the compiled BPF program. It
doesn't result in a failed syscall, an thus auditing a failed LSM
permission check for it is unwanted. For example with SELinux, it causes
a denial to be reported for confined processes running as root, which
tends to be flagged as a problem to be fixed in the policy. Yet
dontauditing or allowing CAP_SYS_ADMIN to the domain may not be
desirable, as it would allow/silence also other checks - either going
against the principle of least privilege or making debugging potentially
harder.
Fix it by changing it from capable() to ns_capable_noaudit(), which
instructs the LSMs to not audit the resulting denials.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lizhi Xu <lizhi.xu@windriver.com>
[ Upstream commit 420c84c330d1688b8c764479e5738bbdbf0a33de ]
The root cause of this issue are:
1. When probing the usbnet device, executing usbnet_link_change(dev, 0, 0);
put the kevent work in global workqueue. However, the kevent has not yet
been scheduled when the usbnet device is unregistered. Therefore, executing
free_netdev() results in the "free active object (kevent)" error reported
here.
2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(),
if the usbnet device is up, ndo_stop() is executed to cancel the kevent.
However, because the device is not up, ndo_stop() is not executed.
The solution to this problem is to cancel the kevent before executing
free_netdev().

[ Upstream commit 09b0cd1297b4dbfe736aeaa0ceeab2265f47f772 ]
hci_cmd_sync_dequeue_once() does lookup and then cancel
the entry under two separate lock sections. Meanwhile,
hci_cmd_sync_work() can also delete the same entry,
leading to double list_del() and "UAF".
Fix this by holding cmd_sync_work_lock across both
lookup and cancel, so that the entry cannot be removed
concurrently.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Iulia Tanasescu <iulia.tanasescu@nxp.com>
[ Upstream commit 83d328a72eff3268ea4c19deb0a6cf4c7da15746 ]
Currently, hci_conn_hash_lookup_big only checks for BIS master connections,
by filtering out connections with the destination address set. This commit
updates this function to also consider BIS slave connections, since it is
also used for a Broadcast Receiver to set an available BIG handle before
issuing the LE BIG Create Sync command.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Lu <chris.lu@mediatek.com>
[ Upstream commit 77343b8b4f87560f8f03e77b98a81ff3a147b262 ]
This patch adds logic to handle power management control when the
Bluetooth function is closed during the SDIO reset sequence.
Specifically, if BT is closed before reset, the driver enables the
SDIO function and sets driver pmctrl. After reset, if BT remains
closed, the driver sets firmware pmctrl and disables the SDIO function.
These changes ensure proper power management and device state consistency
across the reset flow.

[ Upstream commit 0d92808024b4e9868cef68d16f121d509843e80e ]
This fixes the state tracking of advertisement set/instance 0x00 which
is considered a legacy instance and is not tracked individually by
adv_instances list, previously it was assumed that hci_dev itself would
track it via HCI_LE_ADV but that is a global state not specifc to
instance 0x00, so to fix it a new flag is introduced that only tracks the
state of instance 0x00.

Periodic advertising enabled flag cannot be tracked by the enabled
flag since advertising and periodic advertising each can be
enabled/disabled separately from one another causing the states to be
inconsistent when for example an advertising set is disabled its
enabled flag is set to false which is then used for periodic which has
not being disabled.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomeu Vizoso <tomeu@tomeuvizoso.net>
[ Upstream commit a042beac6e6f8ac1e923784cfff98b47cbabb185 ]
The current logic uses the flush sequence from the current address
space. This is harmless when deducing the flush requirements for the
current submit, as either the incoming address space is the same one
as the currently active one or we switch context, in which case the
flush is unconditional.
However, this sequence is also stored as the current flush sequence
of the GPU. If we switch context the stored flush sequence will no
longer belong to the currently active address space. This incoherency
can then cause missed flushes, resulting in translation errors.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Petr Oros <poros@redhat.com>
[ Upstream commit 65f9c4c5888913c2cf5d2fc9454c83f9930d537d ]
The ynl_attr_put_str() function was not including the null terminator
in the attribute length calculation. This caused kernel to reject
CTRL_CMD_GETFAMILY requests with EINVAL:
"Attribute failed policy validation".
For a 4-character family name like "dpll":
- Sent: nla_len=8 (4 byte header + 4 byte string without null)
- Expected: nla_len=9 (4 byte header + 5 byte string with null)
The bug was introduced in commit 15d2540e0d62 ("tools: ynl: check for
overflow of constructed messages") when refactoring from stpcpy() to
strlen(). The original code correctly included the null terminator:
end = stpcpy(ynl_attr_data(attr), str);
attr->nla_len = NLA_HDRLEN + NLA_ALIGN(end -
(char *)ynl_attr_data(attr));
Since stpcpy() returns a pointer past the null terminator, the length
included it. The refactored version using strlen() omitted the +1.
The fix also removes NLA_ALIGN() from nla_len calculation, since
nla_len should contain actual attribute length, not aligned length.
Alignment is only for calculating next attribute position. This makes
the code consistent with ynl_attr_put().
CTRL_ATTR_FAMILY_NAME uses NLA_NUL_STRING policy which requires
null terminator. Kernel validates with memchr() and rejects if not
found.

[ Upstream commit 520ad9e96937e825a117e9f00dd35a3e199d67b5 ]
The dpll.yaml spec incorrectly omitted module-name and clock-id from the
pin-get operation reply specification, even though the kernel DPLL
implementation has always included these attributes in pin-get responses
since the initial implementation.
This spec inconsistency caused issues with the C YNL code generator.
The generated dpll_pin_get_rsp structure was missing these fields.
Fix the spec by adding module-name and clock-id to the pin-attrs reply
specification to match the actual kernel behavior.

------------------
From: Maarten Zanders <maarten@zanders.be>
[ Upstream commit b2dd1d0d322dce5f331961c927e775b84014d5ab ]
When configured for default synchronisation (Rx syncs to Tx) and the
SAI operates in consumer mode (clocks provided externally to Tx), a
synchronisation error occurs on Tx on the first attempt after device
initialisation when the playback stream is started while a capture
stream is already active. This results in channel shift/swap on the
playback stream.
Subsequent streams (ie after that first failing one) always work
correctly, no matter the order, with or without the other stream active.
This issue was observed (and fix tested) on an i.MX6UL board connected
to an ADAU1761 codec, where the codec provides both frame and bit clock
(connected to TX pins).
To fix this, always initialize the 'other' xCR4 and xCR5 registers when
we're starting a stream which is synced to the opposite one, irregardless
of the producer/consumer status.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Palmer <daniel@0x0f.com>
[ Upstream commit 745bae76acdd71709773c129a69deca01036250b ]
Since the allocation of the drivers main structure was changed to
devm_drm_dev_alloc() drm_put_dev()'ing to trigger it to be free'd
should be done by devres.
However, drm_put_dev() is still in the probe error and device remove
paths. When the driver fails to probe warnings like the following are
shown because devres is trying to drm_put_dev() after the driver
already did it.
[ 5.642230] radeon 0000:01:05.0: probe with driver radeon failed with error -22

From: Armin Wolf <W_Armin@gmx.de>
commit 58764259ebe0c9efd569194444629f6b26f86583 upstream.
Usage of the ACPI device should be phased out in the future, as
the driver itself is now using the platform bus.
Replace any usage of struct acpi_device in acpi_fan_get_fst() to
allow users to drop usage of struct acpi_device.
Also extend the integer check to all three package elements.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Damien Le Moal <dlemoal@kernel.org>
commit 12a1c9353c47c0fb3464eba2d78cdf649dee1cf7 upstream.
REQ_OP_ZONE_RESET_ALL is a zone management request. Fix
op_is_zone_mgmt() to return true for that operation, like it already
does for REQ_OP_ZONE_RESET.
While no problems were reported without this fix, this change allows
strengthening checks in various block device drivers (scsi sd,
virtioblk, DM) where op_is_zone_mgmt() is used to verify that a zone
management command is not being issued to a regular block device.
Fixes: 6c1b1da58f8c ("block: add zone open, close and finish operations")

a zoned block device to the explicitly open condition
(BLK_ZONE_COND_EXP_OPEN). As such, it should be considered a write
operation.
Change this operation code to be an odd number to reflect this. The
following operation numbers are changed to keep the numbering compact.
No problems were reported without this change as this operation has no
data. However, this unifies the zone operation to reflect that they
modify the device state and also allows strengthening checks in the
block layer, e.g. checking if this operation is not issued against a
read-only device.
Fixes: 6c1b1da58f8c ("block: add zone open, close and finish operations")

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dapeng Mi <dapeng1.mi@linux.intel.com>
commit 0ba6502ce167fc3d598c08c2cc3b4ed7ca5aa251 upstream.
When running "perf mem record" command on CWF, the below KASAN
global-out-of-bounds warning is seen.
==================================================================
BUG: KASAN: global-out-of-bounds in cmt_latency_data+0x176/0x1b0
Read of size 4 at addr ffffffffb721d000 by task dtlb/9850
Call Trace:
kasan_report+0xb8/0xf0
cmt_latency_data+0x176/0x1b0
setup_arch_pebs_sample_data+0xf49/0x2560
intel_pmu_drain_arch_pebs+0x577/0xb00
handle_pmi_common+0x6c4/0xc80
The issue is caused by below code in __grt_latency_data(). The code
tries to access x86_hybrid_pmu structure which doesn't exist on
non-hybrid platform like CWF.
WARN_ON_ONCE(hybrid_pmu(event->pmu)->pmu_type == hybrid_big)
So add is_hybrid() check before calling this WARN_ON_ONCE to fix the
global-out-of-bounds access issue.

The __devm_regmap_init_slimbus() started to be used instead of
__regmap_init_slimbus() after the commit mentioned above and turns out
the incorrect bus_context pointer (3rd argument) was used in
__devm_regmap_init_slimbus(). It should be just "slimbus" (which is equal
to &slimbus->dev). Correct it. The wcd934x codec seems to be the only or
the first user of devm_regmap_init_slimbus() but we should fix it till
the point where __devm_regmap_init_slimbus() was introduced therefore
two "Fixes" tags.
While at this, also correct the same argument in __regmap_init_slimbus().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miaoqian Lin <linmq006@gmail.com>
commit 07ad45e06b4039adf96882aefcb1d3299fb7c305 upstream.
The function has a memory leak when kvrealloc() fails.
The function directly assigns NULL to the markers pointer, losing the
reference to the previously allocated memory. This causes kvfree() in
pt_dump_init() to free NULL instead of the leaked memory.
Fix by:
1. Using kvrealloc() uniformly for all allocations
2. Using a temporary variable to preserve the original pointer until
allocation succeeds
3. Removing the error path that sets markers_cnt=0 to keep
consistency between markers and markers_cnt
Found via static analysis and this is similar to commit 42378a9ca553
("bpf, verifier: Fix memory leak in array reallocation for stack state")
Fixes: d0e7915d2ad3 ("s390/mm/ptdump: Generate address marker array dynamically")

commit b3fbda1a630a9439c885b2a5dc5230cc49a87e9e upstream.
Waking the device during a GT reset can lead to unintended memory
allocation, which is not allowed since GT resets occur in the reclaim
path. Prevent this by holding a PM reference while a reset is in flight.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Rosca <david.rosca@amd.com>
commit 9e8b3201c7302d5b522ba3535630bed21cc03c27 upstream.
The DRM scheduler tracks who last uses an entity and when that process
is killed blocks all further submissions to that entity.
The problem is that we didn't track who initially created an entity, so
when a process accidently leaked its file descriptor to a child and
that child got killed, we killed the parent's entities.
Avoid that and instead initialize the entities last user on entity
creation. This also allows to drop the extra NULL check.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philipp Stanner <phasta@kernel.org>
commit e0023c8a74028739643aa14bd201c41a99866ca4 upstream.
nouveau_sched_fini() uses a memory barrier before wait_event().
wait_event(), however, is a macro which expands to a loop which might
check the passed condition several times. The barrier would only take
effect for the first check.
Replace the barrier with a function which takes the spinlock.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 926d002e6d7e2f1fd5c1b53cf6208153ee7d380d upstream.
A recent change fixed device reference leaks when looking up drm
platform device driver data during bind() but failed to remove a partial
fix which had been added by commit 80805b62ea5b ("drm/mediatek: Fix
kobject put for component sub-drivers").
This results in a reference imbalance on component bind() failures and
on unbind() which could lead to a user-after-free.
Make sure to only drop the references after retrieving the driver data
by effectively reverting the previous partial fix.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <tzimmermann@suse.de>
commit a9fb41b5def8e1e0103d5fd1453787993587281e upstream.
Preserve the I/O register bits in __ast_write8_i_masked() as specified
by preserve_mask. Accidentally OR-ing the output value into these will
overwrite the register's previous settings.
Fixes display output on the AST2300, where the screen can go blank at
boot. The driver's original commit 312fec1405dd ("drm: Initial KMS
driver for AST (ASpeed Technologies) 2000 series (v2)") already added
the broken code. Commit 6f719373b943 ("drm/ast: Blank with VGACR17 sync
enable, always clear VGACRB6 sync off") triggered the bug.

I think that with this patch (which fixes a bug in the original ast driver affecting AST2300), it is now safe to also
include (in both 6.12.58 AND 6.17.8)
6f719373b943 ("drm/ast: Blank with VGACR17 sync enable, always clear VGACRB6 sync off")
which triggered that bug, and which you dropped from 6.12.55 and 6.17.5, respectively, because of my report
https://lore.kernel.org/dri-devel/a40caf8e-58ad-4f9c-af7f-54f6f69c29bb@googlemail.com/
NB: 6f719373b943 fixed (IIRC) an important issue for AST2500 users. I have tested the combination of both patches in
mainline 6.18-rc2, and they work fine together, and Linus has both of them in his tree since 6.18-rc4.
Also, I tested both of them already on top of 6.12.5 and 6.17.5, and they were fine, too. Please see:

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@amd.com>
commit ba10f8d92a2c026b1052b4c0fa2cd7538838c965 upstream.
[Why]
Newer VPE microcode has functionality that will decrease DPM level
only when a workload has run for 2 or more seconds. If VPE is turned
off before this DPM decrease and the PMFW doesn't reset it when
power gating VPE, the SOC can get stuck with a higher DPM level.
This can happen from amdgpu's ring buffer test because it's a short
quick workload for VPE and VPE is turned off after 1s.
[How]
In idle handler besides checking fences are drained check PMFW version
to determine if it will reset DPM when power gating VPE. If PMFW will
not do this, then check VPE DPM level. If it is not DPM0 reschedule
delayed work again until it is.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joshua Grisham <josh@joshuagrisham.com>
[ Upstream commit 6c00f29f74cb2c063b6f31a0b6d73f9db132b9ac ]
Add support for ACPI fans with _FST to report their speed even if they do
not support fan control.
As suggested by Armin Wolf [1] and per the Windows Thermal Management
Design Guide [2], Samsung Galaxy Book series devices (and possibly many
more devices where the Windows guide was strictly followed) only implement
the _FST method and do not support ACPI-based fan control.
Currently, these fans are not supported by the kernel driver but this patch
will make some very small adjustments to allow them to be supported.
This patch is tested and working for me on a Samsung Galaxy Book2 Pro whose
DSDT (and several other Samsung Galaxy Book series notebooks which
currently have the same issue) can be found at [3].

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit d91a1d129b63614fa4c2e45e60918409ce36db7e ]
Device-managed resources are cleaned up when the driver unbinds from
the underlying device. In our case this is the platform device as this
driver is a platform driver. Registering device-managed resources on
the associated ACPI device will thus result in a resource leak when
this driver unbinds.
Ensure that any device-managed resources are only registered on the
platform device to ensure that they are cleaned up during removal.

From: Emanuele Ghidoli <emanuele.ghidoli@toradex.com>
[ Upstream commit 84a905290cb4c3d9a71a9e3b2f2e02e031e7512f ]
While the DP83867 PHYs report EEE capability through their feature
registers, the actual hardware does not support EEE (see Links).
When the connected MAC enables EEE, it causes link instability and
communication failures.
The issue is reproducible with a iMX8MP and relevant stmmac ethernet port.
Since the introduction of phylink-managed EEE support in the stmmac driver,
EEE is now enabled by default, leading to issues on systems using the
DP83867 PHY.
Call phy_disable_eee during phy initialization to prevent EEE from being
enabled on DP83867 PHYs.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
[ Upstream commit db86f55bf81a3a297be05ee8775ae9a8c6e3a599 ]
A throughput regression of 11% introduced by commit 779b1a1cb13a ("cpuidle:
governors: menu: Avoid selecting states with too much latency") has been
reported and it is related to the case when the menu governor checks if
selecting a proper idle state instead of a polling one makes sense.
In particular, it is questionable to do so if the exit latency of the
idle state in question exceeds the predicted idle duration, so add a
check for that, which is sufficient to make the reported regression go
away, and update the related code comment accordingly.
Fixes: 779b1a1cb13a ("cpuidle: governors: menu: Avoid selecting states with too much latency")

From: Heijligen, Thomas <thomas.heijligen@secunet.com>
commit 309e65d151ab9be1e7b01d822880cd8c4e611dff upstream.
Commit 9e36775c22c7 ("mfd: kempld: Remove custom DMI matching code")
removes the ability to load the driver if no matching system DMI data
is found. Before this commit the driver could be loaded using
alternative methods such as ACPI or `force_device_id` in the absence
of a matching system DMI entry.
Restore this ability while keeping the refactored
`platform_device_info` table.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Owen Gu <guhuinan@xiaomi.com>
commit cfd6f1a7b42f62523c96d9703ef32b0dbc495ba4 upstream.
A race condition occurs when ffs_func_eps_enable() runs concurrently
with ffs_data_reset(). The ffs_data_clear() called in ffs_data_reset()
sets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading
to a NULL pointer dereference when accessing epfile->ep in
ffs_func_eps_enable() after successful usb_ep_enable().
The ffs->epfiles pointer is set to NULL in both ffs_data_clear() and
ffs_data_close() functions, and its modification is protected by the
spinlock ffs->eps_lock. And the whole ffs_func_eps_enable() function
is also protected by ffs->eps_lock.
Thus, add NULL pointer handling for ffs->epfiles in the
ffs_func_eps_enable() function to fix issues

From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com>
[ Upstream commit d42a254633c773921884a19e8a1a0f53a31150c3 ]
In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.
We can avoid that design inelegance, and also have a miniscule
efficiency improvement on the submit from idle path, by introducing a new
drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to
its callers.
v2:
* Remove drm_sched_rq_update_fifo() altogether. (Christian)
v3:
* Improved commit message. (Philipp)

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com>
[ Upstream commit f93126f5d55920d1447ef00a3fbe6706f40f53de ]
When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:
spin_lock(&entity->rq_lock);
spin_lock(&entity->rq->lock);
Rename drm_sched_entity.rq_lock to improve readability. While at it,
re-order that struct's members to make it more obvious what the lock
protects.
v2:
* Rename some rq_lock straddlers in kerneldoc, improve commit text. (Philipp)

In a past bug fix it was forgotten that entity access must be protected
by the entity lock. That's a data race and potentially UB.
Move the spin_unlock() to the appropriate position.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gerd Bayer <gbayer@linux.ibm.com>
[ Upstream commit 0fd20f65df6aa430454a0deed8f43efa91c54835 ]
Do not block PCI config accesses through pci_cfg_access_lock() when
executing the s390 variant of PCI error recovery: Acquire just
device_lock() instead of pci_dev_lock() as powerpc's EEH and
generig PCI AER processing do.
During error recovery testing a pair of tasks was reported to be hung:

No kernel log of the exact same error with an upstream kernel is
available - but the very same deadlock situation can be constructed there,
too:
- task: kmcheck
mlx5_unload_one() tries to acquire devlink lock while the PCI error
recovery code has set pdev->block_cfg_access by way of
pci_cfg_access_lock()
- task: kworker
mlx5_crdump_collect() tries to set block_cfg_access through
pci_cfg_access_lock() while devlink_health_report() had acquired
the devlink lock.
A similar deadlock situation can be reproduced by requesting a
crdump with
> devlink health dump show pci/<BDF> reporter fw_fatal
while PCI error recovery is executed on the same <BDF> physical function
by mlx5_core's pci_error_handlers. On s390 this can be injected with
> zpcictl --reset-fw <BDF>
Tests with this patch failed to reproduce that second deadlock situation,
the devlink command is rejected with "kernel answers: Permission denied" -
and we get a kernel log message of:
mlx5_core 1ed0:00:00.1: mlx5_crdump_collect:50:(pid 254382): crdump: failed to lock vsc gw err -5
because the config read of VSC_SEMAPHORE is rejected by the underlying
hardware.
Two prior attempts to address this issue have been discussed and
ultimately rejected [see link], with the primary argument that s390's
implementation of PCI error recovery is imposing restrictions that
neither powerpc's EEH nor PCI AER handling need. Tests show that PCI
error recovery on s390 is running to completion even without blocking
access to PCI config space.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <hca@linux.ibm.com>
[ Upstream commit 64e2f60f355e556337fcffe80b9bcff1b22c9c42 ]
As reported by Luiz Capitulino enabling HVO on s390 leads to reproducible
crashes. The problem is that kernel page tables are modified without
flushing corresponding TLB entries.
Even if it looks like the empty flush_tlb_all() implementation on s390 is
the problem, it is actually a different problem: on s390 it is not allowed
to replace an active/valid page table entry with another valid page table
entry without the detour over an invalid entry. A direct replacement may
lead to random crashes and/or data corruption.
In order to invalidate an entry special instructions have to be used
(e.g. ipte or idte). Alternatively there are also special instructions
available which allow to replace a valid entry with a different valid
entry (e.g. crdte or cspg).
Given that the HVO code currently does not provide the hooks to allow for
an implementation which is compliant with the s390 architecture
requirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which is
basically a revert of the original patch which enabled it.

[ Upstream commit b832b19318534bb4f1673b24d78037fee339c679 ]
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
[ Upstream commit a5039648f86424885aae37f03dc39bc9cb972ecb ]
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chi Zhang <chizhang@asrmicro.com>
[ Upstream commit 236152dd9b1675a35eee912e79e6c57ca6b6732f ]
In the pin_config_set function, when handling PIN_CONFIG_BIAS_PULL_DOWN or
PIN_CONFIG_BIAS_PULL_UP, the function calls pcs_pinconf_clear_bias()
which writes the register. However, the subsequent operations continue
using the stale 'data' value from before the register write, effectively
causing the bias clear operation to be overwritten and not take effect.
Fix this by reading the 'data' value from the register after calling
pcs_pinconf_clear_bias().
This bug seems to have existed when this code was first merged in commit
9dddb4df90d1 ("pinctrl: single: support generic pinconf").

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Chaignon <paul.chaignon@gmail.com>
[ Upstream commit f41345f47fb267a9c95ca710c33448f8d0d81d83 ]
In the following toy program (reg states minimized for readability), R0
and R1 always have different values at instruction 6. This is obvious
when reading the program but cannot be guessed from ranges alone as
they overlap (R0 in [0; 0xc0000000], R1 in [1024; 0xc0000400]).
0: call bpf_get_prandom_u32#7 ; R0_w=scalar()
1: w0 = w0 ; R0_w=scalar(var_off=(0x0; 0xffffffff))
2: r0 >>= 30 ; R0_w=scalar(var_off=(0x0; 0x3))
3: r0 <<= 30 ; R0_w=scalar(var_off=(0x0; 0xc0000000))
4: r1 = r0 ; R1_w=scalar(var_off=(0x0; 0xc0000000))
5: r1 += 1024 ; R1_w=scalar(var_off=(0x400; 0xc0000000))
6: if r1 != r0 goto pc+1
Looking at tnums however, we can deduce that R1 is always different from
R0 because their tnums don't agree on known bits. This patch uses this
logic to improve is_scalar_branch_taken in case of BPF_JEQ and BPF_JNE.
This change has a tiny impact on complexity, which was measured with
the Cilium complexity CI test. That test covers 72 programs with
various build and load time configurations for a total of 970 test
cases. For 80% of test cases, the patch has no impact. On the other
test cases, the patch decreases complexity by only 0.08% on average. In
the best case, the verifier needs to walk 3% less instructions and, in
the worst case, 1.5% more. Overall, the patch has a small positive
impact, especially for our largest programs.

------------------
From: Takashi Sakamoto <o-takashi@sakamocchi.jp>
[ Upstream commit 696968262aeee51e1c0529c3c060ddd180702e02 ]
The value of OHCI1394_SelfIDCount register includes an error-indicating
bit. It is safer to place the tracepoint probe after validating the
register value.

From: Inochi Amaoto <inochiama@gmail.com>
[ Upstream commit adecf78df945f4c7a1d29111b0002827f487df51 ]
plic_set_affinity() always calls plic_irq_enable(), which clears up the
priority setting even the interrupt is only masked. This unmasks the
interrupt unexpectly.
Replace the plic_irq_enable/disable() with plic_irq_toggle() to avoid
changing the priority setting.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiawei Zhao <phoenix500526@163.com>
[ Upstream commit 758acb9ccfdbf854b55abaceaf1f3f229cde3d19 ]
On x86-64, USDT arguments can be specified using Scale-Index-Base (SIB)
addressing, e.g. "1@-96(%rbp,%rax,8)". The current USDT implementation
in libbpf cannot parse this format, causing `bpf_program__attach_usdt()`
to fail with -ENOENT (unrecognized register).
This patch fixes this by implementing the necessary changes:
- add correct handling for SIB-addressed arguments in `bpf_usdt_arg`.
- add adaptive support to `__bpf_usdt_arg_type` and
`__bpf_usdt_arg_spec` to represent SIB addressing parameters.

[ Upstream commit 592532a77b736b5153e0c2e4c74aa50af0a352ab ]
longhaul_exit() was calling cpufreq_cpu_get(0) without checking
for a NULL policy pointer. On some systems, this could lead to a
NULL dereference and a kernel warning or panic.
This patch adds a check using unlikely() and returns early if the
policy is NULL.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kees Cook <kees@kernel.org>
[ Upstream commit a3fecb9160482367365cc384c59dd220b162b066 ]
While tracking down a problem where constant expressions used by
BUILD_BUG_ON() suddenly stopped working[1], we found that an added static
initializer was convincing the compiler that it couldn't track the state
of the prior statically initialized value. Tracing this down found that
ffs() was used in the initializer macro, but since it wasn't marked with
__attribute__const__, the compiler had to assume the function might
change variable states as a side-effect (which is not true for ffs(),
which provides deterministic math results).
For arc architecture with CONFIG_ISA_ARCV2=y, the __fls() function
uses __builtin_arc_fls() which lacks GCC's const attribute, preventing
compile-time constant folding, and KUnit testing of ffs/fls fails on
arc[3]. A patch[2] to GCC to solve this has been sent.
Add a fix for this by handling compile-time constants with the standard
__builtin_clzl() builtin (which has const attribute) while preserving
the optimized arc-specific builtin for runtime cases. This has the added
benefit of skipping runtime calculation of compile-time constant values.
Even with the GCC bug fixed (which is about "attribute const") this is a
good change to avoid needless runtime costs, and should be done
regardless of the state of GCC's bug.
Build tested ARCH=arc allyesconfig with GCC arc-linux 15.2.0.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Bruel <christian.bruel@foss.st.com>
[ Upstream commit 2ef3886ce626dcdab0cbc452dbbebc19f57133d8 ]
The PCI Local Bus Specification 3.0 (section 6.8.1.6) allows modifying the
low-order bits of the MSI Message DATA register to encode nr_irqs interrupt
numbers in the log2(nr_irqs) bits for the domain.
The problem arises if the base vector (GICV2m base spi) is not aligned with
nr_irqs; in this case, the low-order log2(nr_irqs) bits from the base
vector conflict with the nr_irqs masking, causing the wrong MSI interrupt
to be identified.
To fix this, use bitmap_find_next_zero_area_off() instead of
bitmap_find_free_region() to align the initial base vector with nr_irqs.

From: Shang song (Lenovo) <shangsong2@foxmail.com>
[ Upstream commit 311942ce763e21dacef7e53996d5a1e19b8adab1 ]
If handler_address or mapped VA is NULL, the related buffer address and
VA can be ignored, so make acpi_parse_prmt() skip the current handler
in those cases.

[ Upstream commit 3a351de0d9c86e23b9eca25838b19468aab02f38 ]
Just like the other Vivobooks here, the N6506CU has its keyboard IRQ
described as ActiveLow in the DSDT, which the kernel overrides to
EdgeHigh, causing the internal keyboard not to work.
Add the N6506CU to the irq1_level_low_skip_override[] quirk table to fix
this.

------------------
From: Hans de Goede <hansg@kernel.org>
[ Upstream commit 4405a214df146775338a1e6232701a29024b82e1 ]
Some x86/ACPI laptops with MIPI cameras have a INTC10DE or INTC10E0 ACPI
device in the _DEP dependency list of the ACPI devices for the camera-
sensors (which have flags.honor_deps set).
These devices are for an Intel Vision CVS chip for which an out of tree
driver is available [1].
The camera sensor works fine without a driver being loaded for this
ACPI device on the 2 laptops this was tested on:
ThinkPad X1 Carbon Gen 12 (Meteor Lake)
ThinkPad X1 2-in-1 Gen 10 (Arrow Lake)
For now add these HIDs to acpi_ignore_dep_ids[] so that
acpi_dev_ready_for_enumeration() will return true once the other _DEP
dependencies are met and an i2c_client for the camera sensor will get
instantiated.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
[ Upstream commit 2e82368359f63567862a0d438710ddffcb1ace83 ]
The current behavior of the Step-wise thermal governor is to increase
the cooling level one step at a time after trip point threshold passing
by thermal zone temperature until the temperature stops to rise. Then,
nothing is done until the temperature decreases below the (possibly
updated) trip point threshold, at which point the cooling level is
reduced straight to the applicable minimum.
While this generally works, it is not in agreement with the throttling
logic description comment in step_wise_manage() any more after some
relatively recent changes, and in the case of passive cooling, it may
lead to undesirable performance oscillations between high and low
levels.
For this reason, modify the governor's cooling device state selection
function, get_target_state(), to reduce cooling by one level even if
the temperature is still above the thermal zone threshold, but the
temperature has started to fall down. However, ensure that the cooling
level will remain above the applicable minimum in that case to pull
the zone temperature further down, possibly until it falls below the
trip threshold (which may now be equal to the low temperature of the
trip).
Doing so should help higher performance to be restored earlier in some
cases which is desirable especially for passive trip points with
relatively high hysteresis values.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuande Chen <chuachen@cisco.com>
[ Upstream commit d9d61f1da35038793156c04bb13f0a1350709121 ]
Many AMD CPUs can support this feature now. We would get a wrong CPU DIE
temperature if don't consider this. In low-temperature environments,
the CPU die temperature can drop below zero. So many platforms would like
to make extended temperature range as their default configuration.
Default temperature range (0C to 255.875C).
Extended temperature range (-49C to +206.875C).
Ref Doc: AMD V3000 PPR (Doc ID #56558).

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
[ Upstream commit aae7a2876c3b39d07aa7655ea082af8e7862f3a5 ]
Unlike all the other allocations in this driver, the memory for storing
the pin function descriptions allocated with kcalloc() and later resized
with krealloc() is never freed. Use devres like elsewhere to handle
that. While at it - replace krealloc() with more suitable
devm_krealloc_array().
Note: the logic in this module is pretty convoluted and could probably
use some revisiting, we should probably be able to calculate the exact
amount of memory needed in advance or even skip the allocation
altogether and just add each function to the radix tree separately.

This is mainly because the "name" field of power_supply_desc is a constant.
This patch fixes the issue by reusing the same approach as sbs-battery.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Wang <wangming01@loongson.cn>
[ Upstream commit c33c43f71bda362b292a6e57ac41b64342dc87b3 ]
On certain Loongson platforms, drivers attempting to request a legacy
ISA IRQ directly via request_irq() (e.g., IRQ 4) may fail. The
virtual IRQ descriptor is not fully initialized and lacks a valid irqchip.
This issue does not affect ACPI-enumerated devices described in DSDT,
as their interrupts are properly mapped via the GSI translation path.
This indicates the LPC irqdomain itself is functional but is not correctly
handling direct VIRQ-to-HWIRQ mappings.
The root cause is the use of irq_domain_create_linear(). This API sets
up a domain for dynamic, on-demand mapping, typically triggered by a GSI
request. It does not pre-populate the mappings for the legacy VIRQ range
(0-15). Consequently, if no ACPI device claims a specific GSI
(e.g., GSI 4), the corresponding VIRQ (e.g., VIRQ 4) is never mapped to
the LPC domain. A direct call to request_irq(4, ...) then fails because
the kernel cannot resolve this VIRQ to a hardware interrupt managed by
the LPC controller.
The PCH-LPC interrupt controller is an i8259-compatible legacy device
that requires a deterministic, static 1-to-1 mapping for IRQs 0-15 to
support legacy drivers.
Fix this by replacing irq_domain_create_linear() with
irq_domain_create_legacy(). This API is specifically designed for such
controllers. It establishes the required static 1-to-1 VIRQ-to-HWIRQ
mapping for the entire legacy range (0-15) immediately upon domain
creation. This ensures that any VIRQ in this range is always resolvable,
making direct calls to request_irq() for legacy IRQs function correctly.

------------------
From: Sohil Mehta <sohil.mehta@intel.com>
[ Upstream commit 7f3cfb7943d27a7b61bdac8db739cf0bdc28e87d ]
IO time is considered busy by default for modern Intel processors. The
current check covers recent Family 6 models but excludes the brand new
Families 18 and 19.
According to Arjan van de Ven, the model check was mainly due to a lack
of testing on systems before INTEL_CORE2_MEROM. He suggests considering
all Intel processors as having an efficient idle.
Extend the IO busy classification to all Intel processors starting with
Family 6, including Family 15 (Pentium 4s) and upcoming Families 18/19.
Use an x86 VFM check and move the function to the header file to avoid
using arch-specific #ifdefs in the C file.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hansg@kernel.org>
[ Upstream commit e9dff11a7a50fcef23fe3e8314fafae6d5641826 ]
When deleting the previous walkstate operand stack
acpi_ds_call_control_method() was deleting obj_desc->Method.param_count
operands. But Method.param_count does not necessarily match
this_walk_state->num_operands, it may be either less or more.
After correcting the for loop to check `i < this_walk_state->num_operands`
the code is identical to acpi_ds_clear_operands(), so just outright
replace the code with acpi_ds_clear_operands() to fix this.

A TEE driver doesn't always need to provide a pool if it doesn't
support memory sharing ioctls and can allocate memory for TEE
messages in another way. Although this is mentioned in the
documentation for tee_device_alloc(), it is not handled correctly.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Wagner <wagi@kernel.org>
[ Upstream commit f2537be4f8421f6495edfa0bc284d722f253841d ]
When forcefully shutting down a port via the configfs interface,
nvmet_port_subsys_drop_link() first calls nvmet_port_del_ctrls() and
then nvmet_disable_port(). Both functions will eventually schedule all
remaining associations for deletion.
The current implementation checks whether an association is about to be
removed, but only after the work item has already been scheduled. As a
result, it is possible for the first scheduled work item to free all
resources, and then for the same work item to be scheduled again for
deletion.
Because the association list is an RCU list, it is not possible to take
a lock and remove the list entry directly, so it cannot be looked up
again. Instead, a flag (terminating) must be used to determine whether
the association is already in the process of being deleted.

nvme_fc_unregister_remote removes the remote port on a lport object at
any point in time when there is no active association. This races with
with the reconnect logic, because nvme_fc_create_association is not
taking a lock to check the port_state and atomically increase the
active count on the rport.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kumar Kartikeya Dwivedi <memxor@gmail.com>
[ Upstream commit 2c895133950646f45e5cf3900b168c952c8dbee8 ]
The bpf_cgroup_from_id kfunc relies on cgroup_get_from_id to obtain the
cgroup corresponding to a given cgroup ID. This helper can be called in
a lot of contexts where the current thread can be random. A recent
example was its use in sched_ext's ops.tick(), to obtain the root cgroup
pointer. Since the current task can be whatever random user space task
preempted by the timer tick, this makes the behavior of the helper
unreliable.
Refactor out __cgroup_get_from_id as the non-namespace aware version of
cgroup_get_from_id, and change bpf_cgroup_from_id to make use of it.
There is no compatibility breakage here, since changing the namespace
against which the lookup is being done to the root cgroup namespace only
permits a wider set of lookups to succeed now. The cgroup IDs across
namespaces are globally unique, and thus don't need to be retranslated.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kaushlendra Kumar <kaushlendra.kumar@intel.com>
[ Upstream commit 57b100d4cf14276e0340eecb561005c07c129eb8 ]
The cpupower_write_sysfs() function currently returns -1 on
write failure, but the function signature indicates it should
return an unsigned int. Returning -1 from an unsigned function
results in a large positive value rather than indicating
an error condition.
Fix this by returning 0 on failure, which is more appropriate
for an unsigned return type and maintains consistency with typical
success/failure semantics where 0 indicates failure and non-zero
indicates success (bytes written).

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fenglin Wu <fenglin.wu@oss.qualcomm.com>
[ Upstream commit 41307ec7df057239aae3d0f089cc35a0d735cdf8 ]
The X1E80100 battery management firmware sends a notification with
code 0x83 when the battery charging state changes, such as switching
between fast charge, taper charge, end of charge, or any other error
charging states.
The same notification code is used with bit[8] set when charging stops
because the charge control end threshold is reached. Additionally,
a 2-bit value is included in bit[10:9] with the same code to indicate
the charging source capability, which is determined by the calculated
power from voltage and current readings from PDOs: 2 means a strong
charger over 60W, 1 indicates a weak charger, and 0 means there is no
charging source.
These 3-MSB [10:8] in the notification code is not much useful for now,
hence just ignore them and trigger a power supply change event whenever
0x83 notification code is received. This helps to eliminate the unknown
notification error messages.

Without this, an attempt to register a new cpuidle device without
unregistering the existing one leads to the removal of the existing

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pranav Tyagi <pranav.tyagi03@gmail.com>
[ Upstream commit 6b54082c3ed4dc9821cdf0edb17302355cc5bb45 ]
sys_get_robust_list() and compat_get_robust_list() use ptrace_may_access()
to check if the calling task is allowed to access another task's
robust_list pointer. This check is racy against a concurrent exec() in the
target process.
During exec(), a task may transition from a non-privileged binary to a
privileged one (e.g., setuid binary) and its credentials/memory mappings
may change. If get_robust_list() performs ptrace_may_access() before
this transition, it may erroneously allow access to sensitive information
after the target becomes privileged.
A racy access allows an attacker to exploit a window during which
ptrace_may_access() passes before a target process transitions to a
privileged state via exec().
For example, consider a non-privileged task T that is about to execute a
setuid-root binary. An attacker task A calls get_robust_list(T) while T
is still unprivileged. Since ptrace_may_access() checks permissions
based on current credentials, it succeeds. However, if T begins exec
immediately afterwards, it becomes privileged and may change its memory
mappings. Because get_robust_list() proceeds to access T->robust_list
without synchronizing with exec() it may read user-space pointers from a
now-privileged process.
This violates the intended post-exec access restrictions and could
expose sensitive memory addresses or be used as a primitive in a larger
exploit chain. Consequently, the race can lead to unauthorized
disclosure of information across privilege boundaries and poses a
potential security risk.
Take a read lock on signal->exec_update_lock prior to invoking
ptrace_may_access() and accessing the robust_list/compat_robust_list.
This ensures that the target task's exec state remains stable during the
check, allowing for consistent and synchronized validation of
credentials.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit 5a427fddec5e76360725a0f03df3a2a003efbe2e ]
With latest llvm22, I got the following verification failure:
...

=============
#489/5 verifier_arena_large/big_alloc2:FAIL
The main reason is that 'r8' in insn '70' is not an arena pointer.
Further debugging at llvm side shows that llvm commit ([1]) caused
the failure. For the original code:
page[i] = NULL;
page[i + 1] = NULL;
the llvm transformed it to something like below at source level:
__builtin_memset(&page[i], 0, 16)
Such transformation prevents llvm BPFCheckAndAdjustIR pass from
generating proper addr_space_cast insns ([2]).
Adding support in llvm BPFCheckAndAdjustIR pass should work, but
not sure that such a pattern exists or not in real applications.
At the same time, simply adding a memory barrier between two 'page'
assignment can fix the issue.

The Microsoft Serial Port Console Redirection (SPCR) specification
revision 1.09 comprises additional field: Precise Baud Rate [1].
It is used to describe non-traditional baud rates (such as those
used by high-speed UARTs).
It contains a specific non-zero baud rate which overrides the value
of the Configured Baud Rate field. If this field is zero or not
present, Configured Baud Rate is used.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Markus Stockhausen <markus.stockhausen@gmx.de>
[ Upstream commit e7a25106335041aeca4fdf50a84804c90142c886 ]
The OpenWrt distribution has switched from kernel longterm 6.6 to
6.12. Reports show that devices with the Realtek Otto switch platform
die during operation and are rebooted by the watchdog. Sorting out
other possible reasons the Otto timer is to blame. The platform
currently consists of 4 targets with different hardware revisions.
It is not 100% clear which devices and revisions are affected.
Analysis shows:
A more aggressive sched/deadline handling leads to more timer starts
with small intervals. This increases the bug chances. See
https://marc.info/?l=linux-kernel&m=175276556023276&w=2
Focusing on the real issue a hardware limitation on some devices was
found. There is a minimal chance that a timer ends without firing an
interrupt if it is reprogrammed within the 5us before its expiration
time. Work around this issue by introducing a bounce() function. It
restarts the timer directly before the normal restart functions as
follows:
- Stop timer
- Restart timer with a slow frequency.
- Target time will be >5us
- The subsequent normal restart is outside the critical window
Downstream has already tested and confirmed a patch. See

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Markus Stockhausen <markus.stockhausen@gmx.de>
[ Upstream commit c445bffbf28f721e05d0ce06895045fc62aaff7c ]
During normal operation the timers are reprogrammed including an
interrupt acknowledgement. This has no effect as the whole timer
is setup from scratch afterwards. Especially in an interrupt this
has already been done by rttm_timer_interrupt().
Change the behaviour as follows:
- Use rttm_disable_timer() during reprogramming
- Keep rttm_stop_timer() for all other use cases.
Downstream has already tested and confirmed a patch. See

other info that might help us debug this:
Chain exists of:

Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&q->q_usage_counter(queue)#3);
lock(&q->rq_qos_mutex);
lock(&q->q_usage_counter(queue)#3);
lock(&q->sysfs_lock);
Root cause is that queue_usage_counter is grabbed with rq_qos_mutex
held in blkg_conf_prep(), while queue should be freezed before
rq_qos_mutex from other context.
The blk_queue_enter() from blkg_conf_prep() is used to protect against
policy deactivation, which is already protected with blkcg_mutex, hence
convert blk_queue_enter() to blkcg_mutex to fix this problem. Meanwhile,
consider that blkcg_mutex is held after queue is freezed from policy
deactivation, also convert blkg_alloc() to use GFP_NOIO.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chenghao Duan <duanchenghao@kylinos.cn>
[ Upstream commit d0bf7cd5df18466d969bb60e8890b74cf96081ca ]
In the __arch_prepare_bpf_trampoline() function, retval_off is only
meaningful when save_ret is true, so the current logic is correct.
However, in the original logic, retval_off is only initialized under
certain conditions; for example, in the fmod_ret logic, the compiler is
not aware that the flags of the fmod_ret program (prog) have set
BPF_TRAMP_F_CALL_ORIG, which results in an uninitialized symbol
compilation warning.
So initialize retval_off unconditionally to fix it.

------------------
From: Amery Hung <ameryhung@gmail.com>
[ Upstream commit 8f12d1137c2382c80aada8e05d7cc650cd4e403c ]
It is possible for bpf_xdp_adjust_tail() to free all fragments. The
kfunc currently clears the XDP_FLAGS_HAS_FRAGS bit, but not
XDP_FLAGS_FRAGS_PF_MEMALLOC. So far, this has not caused a issue when
building sk_buff from xdp_buff since all readers of xdp_buff->flags
use the flag only when there are fragments. Clear the
XDP_FLAGS_FRAGS_PF_MEMALLOC bit as well to make the flags correct.

As such if we are starting a persistent connection to a discovery

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit ddb61e737f04e3c6c8299c1e00bf17a42a7f05cf ]
It turns out the second fan on the Dell Precision 490 does not
really support I8K_FAN_TURBO. Setting the fan state to 3 enables
automatic fan control, just like on the other two fans.
The reason why this was misinterpreted as turbo mode was that
the second fan normally spins faster in automatic mode than
in the previous fan states. Yet when in state 3, the fan speed
reacts to heat exposure, exposing the automatic mode setting.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kaushlendra Kumar <kaushlendra.kumar@intel.com>
[ Upstream commit 23199d2aa6dcaf6dd2da772f93d2c94317d71459 ]
Fix incorrect size parameter passed to cpuidle_state_write_file() in
cpuidle_state_disable().
The function was incorrectly using sizeof(disable) which returns the
size of the unsigned int variable (4 bytes) instead of the actual
length of the string stored in the 'value' buffer.
Since 'value' is populated with snprintf() to contain the string
representation of the disable value, we should use the length
returned by snprintf() to get the correct string length for
writing to the sysfs file.
This ensures the correct number of bytes is written to the cpuidle
state disable file in sysfs.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mykyta Yatsenko <yatsenko@meta.com>
[ Upstream commit 105eb5dc74109a9f53c2f26c9a918d9347a73595 ]
bpf_cookie can fail on perf_event_open(), when it runs after the task_work
selftest. The task_work test causes perf to lower
sysctl_perf_event_sample_rate, and bpf_cookie uses sample_freq,
which is validated against that sysctl. As a result,
perf_event_open() rejects the attr if the (now tighter) limit is
exceeded.
>From perf_event_open():
if (attr.freq) {
if (attr.sample_freq > sysctl_perf_event_sample_rate)
return -EINVAL;
} else {
if (attr.sample_period & (1ULL << 63))
return -EINVAL;
}
Switch bpf_cookie to use sample_period, which is not checked against
sysctl_perf_event_sample_rate.

From: Kaushlendra Kumar <kaushlendra.kumar@intel.com>
[ Upstream commit 62127655b7ab7b8c2997041aca48a81bf5c6da0c ]
The fopen_or_die() function was previously hardcoded
to open files in read-only mode ("r"), ignoring the
mode parameter passed to it. This patch corrects
fopen_or_die() to use the provided mode argument,
allowing for flexible file access as intended.
Additionally, the call to fopen_or_die() in
err_on_hypervisor() incorrectly used the mode
"ro", which is not a valid fopen mode. This is
fixed to use the correct "r" mode.

When we are successful in using cpufreq min/max limits,
skip setting the raw MSR limits entirely.
This is necessary to avoid undoing any modification that
the cpufreq driver makes to our sysfs request.
eg. intel_pstate may take our request for a limit
that is valid according to HWP.CAP.MIN/MAX and clip
it to be within the range available in PLATFORM_INFO.

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 364752aa0c6ab0a06a2d5bfdb362c1ca407f1a30 ]
clang-21 warns about one uninitialized variable getting dereferenced
in madera_dev_init:
drivers/mfd/madera-core.c:739:10: error: variable 'mfd_devs' is uninitialized when used here [-Werror,-Wuninitialized]
739 | mfd_devs, n_devs,
| ^~~~~~~~
drivers/mfd/madera-core.c:459:33: note: initialize the variable 'mfd_devs' to silence this warning
459 | const struct mfd_cell *mfd_devs;
| ^
| = NULL
The code is actually correct here because n_devs is only nonzero
when mfd_devs is a valid pointer, but this is impossible for the
compiler to see reliably.
Change the logic to check for the pointer as well, to make this easier
for the compiler to follow.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Kehne <jens.kehne@agilent.com>
[ Upstream commit 9ac4890ac39352ccea132109e32911495574c3ec ]
We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.
To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.
While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.

From: Bastien Curutchet <bastien.curutchet@bootlin.com>
[ Upstream commit 5f4bbee069836e51ed0b6d7e565a292f070ababc ]
When an MFD device is added, a platform_device is allocated. If this
device is linked to a DT description, the corresponding OF node is linked
to the new platform device but the OF node's refcount isn't incremented.
As of_node_put() is called during the platform device release, it leads
to a refcount underflow.
Call of_node_get() to increment the OF node's refcount when the node is
linked to the newly created platform device.

timing_adjust_pending is used to defer certain programming sequences
when OTG timing is about to be changed, like with VRR. Insufficient
checking for timing change in this case caused a regression which
reduces PSR Replay residency.

[Why]
When transitioning between topologies such as multi-display to single
display ODM 2:1, pipes might not be freed before use.
[How]
In dc_commit_streams, commit an additional, minimal transition if
original transition is not seamless to ensure pipes are freed.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Strauss <michael.strauss@amd.com>
[ Upstream commit 2681bf4ae8d24df950138b8c9ea9c271cd62e414 ]
[WHY]
If symclk RCO is enabled, stream encoder may not be receiving an ungated
clock by the time we attempt to set stream attributes when setting dpms
on. Since the clock is gated, register writes to the stream encoder fail.
[HOW]
Move set_stream_attribute call into enable_stream, just after the point
where symclk32_se is ungated.
Logically there is no need to set stream attributes as early as is
currently done in link_set_dpms_on, so this should have no impact beyond
the RCO fix.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Strauss <michael.strauss@amd.com>
[ Upstream commit e3419e1e44b87d4176fb98679a77301b1ca40f63 ]
[WHY]
In the worst case, AUX intra-hop done can take hundreds of milliseconds as
each retimer in a link might have to wait a full AUX_RD_INTERVAL to send
LT abort downstream.
[HOW]
Wait 300ms for each retimer in a link to allow time to propagate a LT abort
without infinitely waiting on intra-hop done.
For no-retimer case, keep the max duration at 10ms.

------------------
From: John Harrison <John.C.Harrison@Intel.com>
[ Upstream commit 45fbb51050e72723c2bdcedc1ce32305256c70ed ]
The GuC load process will abort if certain status codes (which are
indicative of a fatal error) are reported. Otherwise, it keeps waiting
until the 'success' code is returned. New error codes have been added
in recent GuC releases, so add support for aborting on those as well.
v2: Shuffle HWCONFIG_START to the front of the switch to keep the
ordering as per the enum define for clarity (review feedback by
Jonathan). Also add a description for the basic 'invalid init data'
code which was missing.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maarten Lankhorst <dev@lankhorst.se>
[ Upstream commit 1cda3c755bb7770be07d75949bb0f45fb88651f6 ]
I saw an oops in xe_gem_fault when running the xe-fast-feedback
testlist against the realtime kernel without debug options enabled.
The panic happens after core_hotunplug unbind-rebind finishes.
Presumably what happens is that a process mmaps, unlocks because
of the FAULT_FLAG_RETRY_NOWAIT logic, has no process memory left,
causing ttm_bo_vm_dummy_page() to return VM_FAULT_NOPAGE, since
there was nothing left to populate, and then oopses in
"mem_type_is_vram(tbo->resource->mem_type)" because tbo->resource
is NULL.
It's convoluted, but fits the data and explains the oops after
the test exits.

From: Paul Hsieh <Paul.Hsieh@amd.com>
[ Upstream commit 2e72fdba8a32ce062a86571edff4592710c26215 ]
[Why]
The reason some high-resolution monitors fail to display properly
is that this platform does not support sufficiently high DPP and
DISP clock frequencies
[How]
Update DISP and DPP clocks from the smu clock table then DML can
filter these mode if not support.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lijo Lazar <lijo.lazar@amd.com>
[ Upstream commit e87577ef6daa0cfb10ca139c720f0c57bd894174 ]
Cached metrics data validity is 1ms on aldebaran. It's not reasonable
for any client to query gpu_metrics at a faster rate and constantly
interrupt PMFW.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Seyediman Seyedarab <imandevel@gmail.com>
[ Upstream commit 6510b62fe9303aaf48ff136ff69186bcfc32172d ]
snprintf() returns the number of characters that *would* have been
written, which can overestimate how much you actually wrote to the
buffer in case of truncation. That leads to 'data += this' advancing
the pointer past the end of the buffer and size going negative.
Switching to scnprintf() prevents potential buffer overflows and ensures
consistent behavior when building the output string.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Danny Wang <Danny.Wang@amd.com>
[ Upstream commit ad335b5fc9ed1cdeb33fbe97d2969b3a2eedaf3e ]
[WHY&HOW]
The user closed the lid while the system was powering on and opened it
again before the “apply_seamless_boot_optimization” was set to false,
resulting in the eDP remaining blank.
Reset the “apply_seamless_boot_optimization” to false when dpms off.

From: TungYu Lu <tungyu.lu@amd.com>
[ Upstream commit e7496c15d830689cc4fc666b976c845ed2c5ed28 ]
[Why]
Customer reported an issue that OS starts and stops device multiple times
during driver installation. Frequently disabling and enabling OTG may
prevent OTG from being safely disabled and cause incorrect configuration
upon the next enablement.
[How]
Add a wait until OTG_CURRENT_MASTER_EN_STATE is cleared as a short term
solution.

------------------
From: Wake Liu <wakel@google.com>
[ Upstream commit c36748e8733ef9c5f4cd1d7c4327994e5b88b8df ]
The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>`
header, is a GNU extension and not universally available with all
toolchains, such as Clang when used with musl libc.
This can lead to build failures in environments where this header is
missing.
The intention of the code is to determine the bit width of a C `long`.
Replace the non-portable `__WORDSIZE` with the standard and portable
`sizeof(long) * 8` expression to achieve the same result.
This change also removes the inclusion of the now-unused
`<bits/wordsize.h>` header.

------------------
From: Wake Liu <wakel@google.com>
[ Upstream commit bc4c0a48bdad7f225740b8e750fdc1da6d85e1eb ]
The get_next_frame() function in psock_tpacket.c was missing a return
statement in its default switch case, leading to a compiler warning.
This was caused by a `bug_on(1)` call, which is defined as an
`assert()`, being compiled out because NDEBUG is defined during the
build.
Instead of adding a `return NULL;` which would silently hide the error
and could lead to crashes later, this change restores the original
author's intent. By adding `#undef NDEBUG` before including <assert.h>,
we ensure the assertion is active and will cause the test to abort if
this unreachable code is ever executed.

From: Ping-Ke Shih <pkshih@realtek.com>
[ Upstream commit 58de1f91e033b1fface8d8948984583125f93736 ]
The register REG_SYS_CFG1 is used to determine chip basic information
as arguments of following flows, such as download firmware and load PHY
parameters, so driver read the value early (before power-on).
However, the direct IO is disallowed before power-on, or it causes wrong
values, which driver recognizes a chip as a wrong type RF_1T1R, but
actually RF_2T2R, causing driver warns:
rtw88_8822cs mmc1:0001:1: unsupported rf path (1)
Fix it by using indirect IO before power-on.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
[ Upstream commit cc6e8d1ccea792d8550428e0831e3a35b0ccfddc ]
The ivtv driver has a structure named ivtv_open_id that models an open
file handle for the device. It embeds a v4l2_fh instance for file
handles that correspond to a V4L2 video device, and stores a pointer to
that v4l2_fh in struct ivtv_stream to identify which open file handle
owns a particular stream.
In addition to video devices, streams can be owned by ALSA PCM devices.
Those devices do not make use of the v4l2_fh instance for obvious
reasons, but the snd_ivtv_pcm_capture_open() function still initializes
a "fake" v4l2_fh for the sole purpose of using it as an open file handle
identifier. The v4l2_fh is not properly destroyed when the ALSA PCM
device is closed, leading to possible resource leaks.
Fortunately, the v4l2_fh instance pointed to by ivtv_stream is not
accessed, only the pointer value is used for comparison. Replace it with
a pointer to the ivtv_open_id structure that embeds the v4l2_fh, and
don't initialize the v4l2_fh for ALSA PCM devices.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
[ Upstream commit 19fb9c5b815f70eb90d5b545f65b83bc9c490ecd ]
The v4l2_fh initialized and added in vpu_v4l2_open() is delete and
cleaned up when the last reference to the vpu_inst is released. This may
happen later than at vpu_v4l2_close() time.
Not deleting and cleaning up the v4l2_fh when closing the file handle to
the video device is not ideal, as the v4l2_fh will still be present in
the video device's fh_list, and will store a copy of events queued to
the video device. There may also be other side effects of keeping alive
an object that represents an open file handle after the file handle is
closed.
The v4l2_fh instance is embedded in the vpu_inst structure, and is
accessed in two different ways:
- in vpu_notify_eos() and vpu_notify_source_change(), to queue V4L2
events to the file handle ; and
- through the driver to access the v4l2_fh.m2m_ctx pointer.
The v4l2_fh.m2m_ctx pointer is not touched by v4l2_fh_del() and
v4l2_fh_exit(). It is set to NULL by the driver when closing the file
handle, in vpu_v4l2_close().
The vpu_notify_eos() and vpu_notify_source_change() functions are called
in vpu_set_last_buffer_dequeued() and vdec_handle_resolution_change()
respectively, only if the v4l2_fh.m2m_ctx pointer is not NULL. There is
therefore a guarantee that no new event will be queued to the v4l2_fh
after vpu_v4l2_close() destroys the m2m_ctx.
The vpu_notify_eos() function is also called from vpu_vb2_buf_finish(),
which is guaranteed to be called for all queued buffers when
vpu_v4l2_close() calls v4l2_m2m_ctx_release(), and will not be called
later.
It is therefore safe to assume that the driver will not touch the
v4l2_fh, except to check the m2m_ctx pointer, after vpu_v4l2_close()
destroys the m2m_ctx. We can safely delete and cleanup the v4l2_fh
synchronously in vpu_v4l2_close().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit eea4f89b6461294ed6bea1d3285bb3f79c09a041 ]
The driver tries to calculate the value for REG_WAKEUP_TIME. However,
the calculation itself is not correct, and to add on it, the resulting
value is almost always larger than the field's size, so the actual
result is more or less random.
According to the docs, figuring out the value for REG_WAKEUP_TIME
requires HW characterization and there's no way to have a generic
algorithm to come up with the value. That doesn't help at all...
However, we know that the value must be smaller than the line time, and,
at least in my understanding, the proper value for it is quite small.
Testing shows that setting it to 1/10 of the line time seems to work
well. All video modes from my HDMI monitor work with this algorithm.
Hopefully we'll get more information on how to calculate the value, and
we can then update this.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 7070f55f294745c5a3c033623b76309f3512be67 ]
While the cdns-dsi does not support DSI burst mode, the burst mode is
essentially DSI event mode with more versatile clocking and timings.
Thus cdns-dsi doesn't need to fail if the DSI peripheral driver requests
MIPI_DSI_MODE_VIDEO_BURST.
In my particular use case, this allows the use of ti-sn65dsi83 driver.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Wunner <lukas@wunner.de>
[ Upstream commit 45bc82563d5505327d97963bc54d3709939fa8f8 ]
After a Fatal Error has been reported by a device and has been recovered
through a Secondary Bus Reset, AER updates the device's error_state to
pci_channel_io_normal before invoking its driver's ->resume() callback.
By contrast, EEH updates the error_state earlier, namely after resetting
the device and before invoking its driver's ->slot_reset() callback.
Commit c58dc575f3c8 ("powerpc/pseries: Set error_state to
pci_channel_io_normal in eeh_report_reset()") explains in great detail
that the earlier invocation is necessitated by various drivers checking
accessibility of the device with pci_channel_offline() and avoiding
accesses if it returns true. It returns true for any other error_state
than pci_channel_io_normal.
The device should be accessible already after reset, hence the reasoning
is that it's safe to update the error_state immediately afterwards.
This deviation between AER and EEH seems problematic because drivers
behave differently depending on which error recovery mechanism the
platform uses. Three drivers have gone so far as to update the
error_state themselves, presumably to work around AER's behavior.
For consistency, amend AER to update the error_state at the same recovery
steps as EEH. Drop the now unnecessary workaround from the three drivers.
Keep updating the error_state before ->resume() in case ->error_detected()
or ->mmio_enabled() return PCI_ERS_RESULT_RECOVERED, which causes
->slot_reset() to be skipped. There are drivers doing this even for Fatal
Errors, e.g. mhi_pci_error_detected().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
[ Upstream commit 8ba38a7a9a699905b84fa97578a8291010dec273 ]
emulate_vsyscall() expects to see X86_PF_INSTR in PFEC on a vsyscall
page fault, but the CPU does not report X86_PF_INSTR if neither
X86_FEATURE_NX nor X86_FEATURE_SMEP are enabled.
X86_FEATURE_NX should be enabled on nearly all 64-bit CPUs, except for
early P4 processors that did not support this feature.
Instead of explicitly checking for X86_PF_INSTR, compare the fault
address to RIP.
On machines with X86_FEATURE_NX enabled, issue a warning if RIP is equal
to fault address but X86_PF_INSTR is absent.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
[ Upstream commit 66ceb45b7d7e9673254116eefe5b6d3a44eba267 ]
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Wunner <lukas@wunner.de>
[ Upstream commit 5d03847175e81e86d4865456c15638faaf7c0634 ]
The thunderbolt driver sets up device link dependencies from hotplug ports
to the Host Router (aka Native Host Interface, NHI). When resuming from
system sleep, this allows the Host Router to re-establish tunnels to
attached Thunderbolt devices before the hotplug ports resume.
To identify the hotplug ports, the driver utilizes the is_hotplug_bridge
flag which also encompasses ACPI slots handled by the ACPI hotplug driver.
Thunderbolt hotplug ports are always Hot-Plug Capable PCIe ports, so it is
more apt to identify them with the is_pciehp flag.
Similarly, hotplug ports on older Thunderbolt controllers have broken MSI
support and are quirked to use legacy INTx interrupts instead. The quirk
identifies them with is_hotplug_bridge, even though all affected ports are
also matched by is_pciehp. So use is_pciehp here as well.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
[ Upstream commit 3fc36ae6abd263a5cbf93b2f5539eccc1fc753f7 ]
After commit 84a9582fd203 ("serial: core: Start managing serial controllers
to enable runtime PM") serial drivers need to provide a device in
struct uart_port.dev otherwise an oops happens. To fix this issue
for ip22zilog driver switch driver to a platform driver and setup
the serial device in sgi-ip22 code.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Schnelle <schnelle@linux.ibm.com>
[ Upstream commit 704e5dd1c02371dfc7d22e1520102b197a3b628b ]
Ever since uevent support was added for AER and EEH with commit
856e1eb9bdd4 ("PCI/AER: Add uevents in AER and EEH error/resume"), it
reported PCI_ERS_RESULT_NONE as uevent when recovery begins.
Commit 7b42d97e99d3 ("PCI/ERR: Always report current recovery status for
udev") subsequently amended AER to report the actual return value of
error_detected().
Make the same change to EEH to align it with AER and s390.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit 3d05b24429e1de7a17c8fdccb04a04dbc8ad297b ]
If a backup port is configured for a bridge port, the bridge will
redirect known unicast traffic towards the backup port when the primary
port is administratively up but without a carrier. This is useful, for
example, in MLAG configurations where a system is connected to two
switches and there is a peer link between both switches. The peer link
serves as the backup port in case one of the switches loses its
connection to the multi-homed system.
In order to avoid flooding when the primary port loses its carrier, the
bridge does not flush dynamic FDB entries pointing to the port upon STP
disablement, if the port has a backup port.
The above means that known unicast traffic destined to the primary port
will be blackholed when the port is put administratively down, until the
FDB entries pointing to it are aged-out.
Given that the current behavior is quite weird and unlikely to be
depended on by anyone, amend the bridge to redirect to the backup port
also when the primary port is administratively down and not only when it
does not have a carrier.
The change is motivated by a report from a user who expected traffic to
be redirected to the backup port when the primary port was put
administratively down while debugging a network issue.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Wang <peter.wang@mediatek.com>
[ Upstream commit aa86602a483ba48f51044fbaefa1ebbf6da194a4 ]
Move the configuration of the Auto-Hibern8 (AHIT) timer from the
post-link stage to the 'fixup_dev_quirks' function. This change allows
setting the AHIT based on the vendor requirements:
(a) Samsung: 3.5 ms
(b) Micron: 2 ms
(c) Others: 1 ms
Additionally, the clock gating timer is adjusted based on the AHIT
scale, with a maximum setting of 10 ms. This ensures that the clock
gating delay is appropriately configured to match the AHIT settings.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Wang <peter.wang@mediatek.com>
[ Upstream commit 7212d624f8638f8ea8ad1ecbb80622c7987bc7a1 ]
Address a failure in switching to PWM mode by ensuring proper
configuration of power modes and adaptation settings. The changes
include checks for SLOW_MODE and adjustments to the desired working mode
and adaptation configuration based on the device's power mode and
hardware version.

From: Charalampos Mitrodimas <charmitro@posteo.net>
[ Upstream commit 2327a3d6f65ce2fe2634546dde4a25ef52296fec ]
Fix field-spanning memcpy warnings in ah6_output() and
ah6_output_done() where extension headers are copied to/from IPv6
address fields, triggering fortify-string warnings about writes beyond
the 16-byte address fields.
memcpy: detected field-spanning write (size 40) of single field "&top_iph->saddr" at net/ipv6/ah6.c:439 (size 16)
WARNING: CPU: 0 PID: 8838 at net/ipv6/ah6.c:439 ah6_output+0xe7e/0x14e0 net/ipv6/ah6.c:439
The warnings are false positives as the extension headers are
intentionally placed after the IPv6 header in memory. Fix by properly
copying addresses and extension headers separately, and introduce
helper functions to avoid code duplication.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
[ Upstream commit eecd203ada43a4693ce6fdd3a58ae10c7819252c ]
syzbot is reporting that imon has three problems which result in
hung tasks due to forever holding device lock [1].
First problem is that when usb_rx_callback_intf0() once got -EPROTO error
after ictx->dev_present_intf0 became true, usb_rx_callback_intf0()
resubmits urb after printk(), and resubmitted urb causes
usb_rx_callback_intf0() to again get -EPROTO error. This results in
printk() flooding (RCU stalls).
Alan Stern commented [2] that
In theory it's okay to resubmit _if_ the driver has a robust
error-recovery scheme (such as giving up after some fixed limit on the
number of errors or after some fixed time has elapsed, perhaps with a
time delay to prevent a flood of errors). Most drivers don't bother to
do this; they simply give up right away. This makes them more
vulnerable to short-term noise interference during USB transfers, but in
reality such interference is quite rare. There's nothing really wrong
with giving up right away.
but imon has a poor error-recovery scheme which just retries forever;
this behavior should be fixed.
Since I'm not sure whether it is safe for imon users to give up upon any
error code, this patch takes care of only union of error codes chosen from
modules in drivers/media/rc/ directory which handle -EPROTO error (i.e.
ir_toy, mceusb and igorplugusb).
Second problem is that when usb_rx_callback_intf0() once got -EPROTO error
before ictx->dev_present_intf0 becomes true, usb_rx_callback_intf0() always
resubmits urb due to commit 8791d63af0cf ("[media] imon: don't wedge
hardware after early callbacks"). Move the ictx->dev_present_intf0 test
introduced by commit 6f6b90c9231a ("[media] imon: don't parse scancodes
until intf configured") to immediately before imon_incoming_packet(), or
the first problem explained above happens without printk() flooding (i.e.
hung task).
Third problem is that when usb_rx_callback_intf0() is not called for some
reason (e.g. flaky hardware; the reproducer for this problem sometimes
prevents usb_rx_callback_intf0() from being called),
wait_for_completion_interruptible() in send_packet() never returns (i.e.
hung task). As a workaround for such situation, change send_packet() to
wait for completion with timeout of 10 seconds.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Karunika Choo <karunika.choo@arm.com>
[ Upstream commit e322a4844811b54477b7072eb40dc9e402a1725d ]
In certain scenarios, it is possible for multiple cache flushes to be
requested before the previous one completes. This patch introduces the
cache_flush_lock mutex to serialize these operations and ensure that
any requested cache flushes are completed instead of dropped.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com>
[ Upstream commit f345a4798dab800159b09d088e7bdae0f16076c3 ]
The already fixed bug in SDL only affected conditional effects. This
should fix FFB in Forza Horizion 4/5 on Moza Devices as Forza Horizon
flips the constant force direction instead of using negative magnitude
values.
Changing the direction in the effect directly in pidff_upload_effect()
would affect it's value in further operations like comparing to the old
effect and/or just reading the effect values in the user application.
This, in turn, would lead to constant PID_SET_EFFECT spam as the effect
direction would constantly not match the value that's set by the
application.
This way, it's still transparent to any software/API.
Only affects conditional effects now so it's better for it to explicitly
state that in the name. If any HW ever needs fixed direction for other
effects, we'll add more quirks.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>
[ Upstream commit cb640b2ca54617f4a9d4d6efd5ff2afd6be11f19 ]
Detecting the monitor for DisplayPort targets is more complicated than
just reading the HPD pin level: it requires reading the DPCD in order to
check what kind of device is attached to the port and whether there is
an actual display attached.
In order to let DRM framework handle such configurations, disable
DRM_BRIDGE_OP_DETECT for dp-connector devices, letting the actual DP
driver perform detection. This still keeps DRM_BRIDGE_OP_HPD enabled, so
it is valid for the bridge to report HPD events.
Currently inside the kernel there are only two targets which list
hpd-gpios for dp-connector devices: arm64/qcom/qcs6490-rb3gen2 and
arm64/qcom/sa8295p-adp. Both should be fine with this change.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kent Russell <kent.russell@amd.com>
[ Upstream commit 0ed704d058cec7643a716a21888d58c7d03f2c3e ]
HMM assumes that pages have READ permissions by default. Inside
svm_range_validate_and_map, we add READ permissions then add WRITE
permissions if the VMA isn't read-only. This will conflict with regions
that only have PROT_WRITE or have PROT_NONE. When that happens,
svm_range_restore_work will continue to retry, silently, giving the
impression of a hang if pr_debug isn't enabled to show the retries..
If pages don't have READ permissions, simply unmap them and continue. If
they weren't mapped in the first place, this would be a no-op. Since x86
doesn't support write-only, and PROT_NONE doesn't allow reads or writes
anyways, this will allow the svm range validation to continue without
getting stuck in a loop forever on mappings we can't use with HMM.

avg sample info is a bit field coded inside the following
bits: 5,6,7 and 8 of a device status register.
Channel num info the same, but over bits: 1, 2 and 3.
Mask both values in order to avoid touching other register bits,
since the first info (avg sample), came from DT.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haibo Chen <haibo.chen@nxp.com>
[ Upstream commit 12c9b09e981ab14ebec8e4eefa946cbd26dd306b ]
ADC calibration might fail because of the noise on reference voltage.
To avoid calibration fail, need to meet the following requirement:
ADC reference voltage Noise < 1.8V * 1/2^ENOB
For the case which the ADC reference voltage on board do not meet
the requirement, still load the calibrated values, so ADC can also
work but maybe not that accurate.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: raub camaioni <raubcameo@gmail.com>
[ Upstream commit 956606bafb5fc6e5968aadcda86fc0037e1d7548 ]
This fix is already present in f_ecm.c and was never
propagated to f_ncm.c
When creating multiple NCM ethernet devices
on a composite usb gadget device
each MAC address on the HOST side will be identical.
Having the same MAC on different network interfaces is bad.
This fix updates the MAC address inside the
ncm_strings_defs global during the ncm_bind call.
This ensures each device has a unique MAC.
In f_ecm.c ecm_string_defs is updated in the same way.
The defunct MAC assignment in ncm_alloc has been removed.

error fails all I/O and doesn't pass anything on, but doing the same for
integrity I/O work just fine :)
This helps to make about two dozen xfstests test cases pass on PI capable
devices.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zijun Hu <zijun.hu@oss.qualcomm.com>
[ Upstream commit 52e2bb5ff089d65e2c7d982fe2826dc88e473d50 ]
For miscdevice who wants dynamic minor, it may fail to be registered again
without reinitialization after being de-registered, which is illustrated
by kunit test case miscdev_test_dynamic_reentry() newly added.
There is a real case found by cascardo when a part of minor range were
contained by range [0, 255):
1) wmi/dell-smbios registered minor 122, and acpi_thermal_rel registered
minor 123
2) unbind "int3400 thermal" driver from its device, this will de-register
acpi_thermal_rel
3) rmmod then insmod dell_smbios again, now wmi/dell-smbios is using minor
123
4) bind the device to "int3400 thermal" driver again, acpi_thermal_rel
fails to register.
Some drivers may reuse the miscdevice structure after they are deregistered
If the intention is to allocate a dynamic minor, if the minor number is not
reset to MISC_DYNAMIC_MINOR before calling misc_register(), it will try to
register a previously dynamically allocated minor number, which may have
been registered by a different driver.
One such case is the acpi_thermal_rel misc device, registered by the
int3400 thermal driver. If the device is unbound from the driver and later
bound, if there was another dynamic misc device registered in between, it
would fail to register the acpi_thermal_rel misc device. Other drivers
behave similarly.
Actually, this kind of issue is prone to happen if APIs
misc_register()/misc_deregister() are invoked by driver's
probe()/remove() separately.
Instead of fixing all the drivers, just reset the minor member to
MISC_DYNAMIC_MINOR in misc_deregister() in case it was a dynamically
allocated minor number, as error handling of misc_register() does.

[ Upstream commit 1ba0fb42aa6a5f072b1b8c0b0520b32ad4ef4b45 ]
misc_open() may request module for miscdevice with dynamic minor, which
is meaningless since:
- The dynamic minor allocated is unknown in advance without registering
miscdevice firstly.
- Macro MODULE_ALIAS_MISCDEV() is not applicable for dynamic minor.
Fix by only requesting module for miscdevice with fixed minor.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Paasch <cpaasch@openai.com>
[ Upstream commit b0ac6d3b56a2384db151696cfda2836a8a961b6d ]
When removing a nexthop, commit
90f33bffa382 ("nexthops: don't modify published nexthop groups") added a
call to synchronize_rcu() (later changed to _net()) to make sure
everyone sees the new nexthop-group before the rtnl-lock is released.
When one wants to delete a large number of groups and nexthops, it is
fastest to first flush the groups (ip nexthop flush groups) and then
flush the nexthops themselves (ip -6 nexthop flush). As that way the
groups don't need to be rebalanced.
However, `ip -6 nexthop flush` will still take a long time if there is
a very large number of nexthops because of the call to
synchronize_net(). Now, if there are no more groups, there is no point
in calling synchronize_net(). So, let's skip that entirely by checking
if nh->grp_list is empty.
This gives us a nice speedup:
BEFORE:

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oleksij Rempel <o.rempel@pengutronix.de>
[ Upstream commit ee0aace5f844ef59335148875d05bec8764e71e8 ]
The stmmac_rx function would previously set skb->ip_summed to
CHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabled
and the packet was of a known IP ethertype.
However, this logic failed to check if the hardware had actually
reported a checksum error. The hardware status, indicating a header or
payload checksum failure, was being ignored at this stage. This could
cause corrupt packets to be passed up the network stack as valid.
This patch corrects the logic by checking the `csum_none` status flag,
which is set when the hardware reports a checksum error. If this flag
is set, skb->ip_summed is now correctly set to CHECKSUM_NONE,
ensuring the kernel's network stack will perform its own validation and
properly handle the corrupt packet.

From: Kuniyuki Iwashima <kuniyu@google.com>
[ Upstream commit 9d85c565a7b7c78b732393c02bcaa4d5c275fe58 ]
Initially, trace_sock_exceed_buf_limit() was invoked when
__sk_mem_raise_allocated() failed due to the memcg limit or the
global limit.
However, commit d6f19938eb031 ("net: expose sk wmem in
sock_exceed_buf_limit tracepoint") somehow suppressed the event
only when memcg failed to charge for SK_MEM_RECV, although the
memcg failure for SK_MEM_SEND still triggers the event.
Let's restore the event for SK_MEM_RECV.

[ Upstream commit 6238784e502b6a9fbeb3a6b77284b29baa4135cc ]
The error handling path in pci_p2pdma_add_resource() contains a bug in its
`pgmap_free` label.
Memory is allocated for the `p2p_pgmap` struct, and the pointer is stored
in `p2p_pgmap`. However, the error path calls devm_kfree() with `pgmap`,
which is a pointer to a member field within the `p2p_pgmap` struct, not the
base pointer of the allocation.
Correct the bug by passing the correct base pointer, `p2p_pgmap`, to
devm_kfree().

Just add fixed struct size validations for UAC2 and UAC3 effect
units. The descriptor has a variable-length array, so it should be
validated with a proper function later once when the unit is really
parsed and used by the driver (currently only referred partially for
the input terminal parsing).

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 02614eee26fbdfd73b944769001cefeff6ed008c ]
idpf has a limit on number of scatter-gather frags
that can be used per segment.
Currently, idpf_tx_start() checks if the limit is hit
and forces a linearization of the whole packet.
This requires high order allocations that can fail
under memory pressure. A full size BIG-TCP packet
would require order-7 alocation on x86_64 :/
We can move the check earlier from idpf_features_check()
for TSO packets, to force GSO in this case, removing the
cost of a big copy.
This means that a linearization will eventually happen
with sizes smaller than one MSS.
__idpf_chk_linearize() is renamed to idpf_chk_tso_segment()
and moved to idpf_lib.c

------------------
From: Andrew Davis <afd@ti.com>
[ Upstream commit 6e29c30d8ddea6109ea7e0b9f17e7841df0794ea ]
Module aliases are used by userspace to identify the correct module to
load for a detected hardware. The currently supported RPMSG device IDs for
this module include "rpmsg-raw", but the module alias is "rpmsg_chrdev".
Use the helper macro MODULE_DEVICE_TABLE(rpmsg) to export the correct
supported IDs. And while here, to keep backwards compatibility we also add
the other ID "rpmsg_chrdev" so that it is also still exported as an alias.
This has the side benefit of adding support for some legacy firmware
which still uses the original "rpmsg_chrdev" ID. This was the ID used for
this driver before it was upstreamed (as reflected by the module alias).

------------------
From: Oscar Maes <oscmaes92@gmail.com>
[ Upstream commit 1b8c5fa0cb35efd08f07f700e6d78a541ebabe26 ]
Currently, ip_extract_route_hint uses RTN_BROADCAST to decide
whether to use the route dst hint mechanism.
This check is too strict, as it prevents directed broadcast
routes from using the hint, resulting in poor performance
during bursts of directed broadcast traffic.
Fix this in ip_extract_route_hint and modify ip_route_use_hint
to preserve the intended behaviour.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chandrakanth Patil <chandrakanth.patil@broadcom.com>
[ Upstream commit 829fa1582b6ff607b0e2fe41ba1c45c77f686618 ]
Firmware can enter a transient fault while creating operational queues.
The driver fails the load immediately.
Add a retry loop that checks controller status and history bit after
queue creation. If either indicates a fault, retry init up to a set
limit before failing.

From: Francisco Gutierrez <frankramirez@google.com>
[ Upstream commit d6477ee38ccfbeaed885733c13f41d9076e2f94a ]
Eliminate the use of static variables within the log pull implementation
to resolve a race condition and prevent data gaps when pulling logs from
multiple controllers in parallel, ensuring each operation is properly
isolated.

------------------
From: Heiner Kallweit <hkallweit1@gmail.com>
[ Upstream commit a0f849c1cc6df0db9083b4c81c05a5456b1ed0fb ]
fixed_phy_register() creates and registers the phy_device. To be
symmetric, we should not only unregister, but also free the phy_device
in fixed_phy_unregister(). This allows to simplify code in users.
Note wrt of_phy_deregister_fixed_link():
put_device(&phydev->mdio.dev) and phy_device_free(phydev) are identical.

returns failure. It should be skipped for this case from

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Lipski <ivan.lipski@amd.com>
[ Upstream commit 8a359f0f138d5ac7ceffd21b73279be50e516c0a ]
[Why]
For the HW cursor, its current position in the pipe_ctx->stream struct is
not affected by the 180 rotation, i. e. the top left corner is still at
0,0. However, the DPP & HUBP set_cursor_position functions require rotated
position.
The current approach is hard-coded for ODM 2:1, thus it's failing for
ODM 4:1, resulting in a double cursor.
[How]
Instead of calculating the new cursor position relatively to the
viewports, we calculate it using a viewavable clip_rect of each plane.
The clip_rects are first offset and scaled to the same space as the
src_rect, i. e. Stream space -> Plane space.
In case of a pipe split, which divides the plane into 2 or more viewports,
the clip_rect is the union of all the viewports of the given plane.
With the assumption that the viewports in HUBP's set_cursor_position are
in the Plane space as well, it should produce a correct cursor position
for any number of pipe splits.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Amber Lin <Amber.Lin@amd.com>
[ Upstream commit f3820e9d356132e18405cd7606e22dc87ccfa6d1 ]
When KFD asks CP to preempt queues, other than preempt CP queues, CP
also requests SDMA to preempt SDMA queues with UNMAP_LATENCY timeout.
Currently queue_preemption_timeout_ms is 9000 ms by default but can be
configured via module parameter. KFD_UNMAP_LATENCY_MS is hard coded as
4000 ms though. This patch ties KFD_UNMAP_LATENCY_MS to
queue_preemption_timeout_ms so in a slow system such as emulator, both
CP and SDMA slowness are taken into account.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
[ Upstream commit 6d47b4f08436cb682fb2644e6265a3897fd42a77 ]
A partitioned system configured with only one package and one compute
die, warning will be generated for duplicate sysfs entry. This typically
occurs during the platform bring-up phase.
Partitioned systems expose dies, equivalent to TPMI compute domains,
through the CPUID. Each partitioned system must contains at least one
compute die per partition, resulting in a minimum of two dies per
package. Hence the function topology_max_dies_per_package() returns at
least two, and the condition "topology_max_dies_per_package() > 1"
prevents the creation of a root domain.
In this case topology_max_dies_per_package() will return 1 and root
domain will be created for partition 0 and a duplicate sysfs warning
for partition 1 as both partitions have same package ID.
To address this also check for non zero partition in addition to
topology_max_dies_per_package() > 1.

[Why]
-Pipe splitting allows for clocks to be reduced, but when using TMDS 420,
reduced clocks lead to missed clocks cycles on clock resyncing

------------------
From: Clay King <clayking@amd.com>
[ Upstream commit 306cbcc6f687d791ab3cc8fbbe30f5286fd0d1e5 ]
[Why & How]
Previously, when calculating dto phase, we would incorrectly fail when phase
<=0 without additionally checking for the integer value. This meant that
calculations would incorrectly fail when the desired pixel clock was an exact
multiple of the reference clock.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Timur Kristóf <timur.kristof@gmail.com>
[ Upstream commit 585b2f685c56c5095cc22c7202bf74d8e9a73cdd ]
Update the legacy (non-DC) display code to respect the maximum
pixel clock for HDMI and DVI-D. Reject modes that would require
a higher pixel clock than can be supported.
Also update the maximum supported HDMI clock value depending on
the ASIC type.
For reference, see the DC code:
check max_hdmi_pixel_clock in dce*_resource.c
v2:
Fix maximum clocks for DVI-D and DVI/HDMI adapters.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Parthiban Veerasooran <parthiban.veerasooran@microchip.com>
[ Upstream commit 34c21e91192aa1ff66f9d6cef8132717840d04e6 ]
Introduce support for standard MII ioctl operations in the LAN865x
Ethernet driver by implementing the .ndo_eth_ioctl callback. This allows
PHY-related ioctl commands to be handled via phy_do_ioctl_running() and
enables support for ethtool and other user-space tools that rely on ioctl
interface to perform PHY register access using commands like SIOCGMIIREG
and SIOCSMIIREG.
This feature enables improved diagnostics and PHY configuration
capabilities from userspace.

------------------
From: Qianfeng Rong <rongqianfeng@vivo.com>
[ Upstream commit 4c634b6b3c77bba237ee64bca172e73f9cee0cb2 ]
As noted in the kernel documentation [1], open-coded multiplication in
allocator arguments is discouraged because it can lead to integer overflow.
Use kcalloc() to gain built-in overflow protection, making memory
allocation safer when calculating allocation size compared to explicit
multiplication. Similarly, use size_add() instead of explicit addition
for 'uobj_chunk_num + sobj_chunk_num'.

From: Bharat Uppal <bharat.uppal@samsung.com>
[ Upstream commit 6d55af0f0740bf3d77943425fdafb77dc0fa6bb9 ]
On FSD platform, gating the reference clock (ref_clk) and putting the
UFS device in reset by asserting the reset signal during UFS suspend,
improves the power savings and ensures the PHY is fully turned off.
These operations are added as FSD specific suspend hook to avoid
unintended side effects on other SoCs supported by this driver.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miroslav Lichvar <mlichvar@redhat.com>
[ Upstream commit 5a8c02a6bf52b1cf9cfb7868a8330f7c3c6aebe9 ]
Networking drivers implementing PTP clocks and kernel socket code
handling hardware timestamps use the 64-bit signed ktime_t type counting
nanoseconds. When a PTP clock reaches the maximum value in year 2262,
the timestamps returned to applications will overflow into year 1667.
The same thing happens when injecting a large offset with
clock_adjtime(ADJ_SETOFFSET).
The commit 7a8e61f84786 ("timekeeping: Force upper bound for setting
CLOCK_REALTIME") limited the maximum accepted value setting the system
clock to 30 years before the maximum representable value (i.e. year
2232) to avoid the overflow, assuming the system will not run for more
than 30 years.
Enforce the same limit for PTP clocks. Don't allow negative values and
values closer than 30 years to the maximum value. Drivers may implement
an even lower limit if the hardware registers cannot represent the whole
interval between years 1970 and 2262 in the required resolution.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Andreatta <thomasandreatta2000@gmail.com>
[ Upstream commit d9a3e9929452780df16f3414f0d59b5f69d058cf ]
This patch modifies the type of setup_xref from void to int and handles
errors since the function can fail.
`setup_xref` now returns the (eventual) error from
`dmae_set_dmars`|`dmae_set_chcr`, while `shdma_tx_submit` handles the
result, removing the chunks from the queue and marking PM as idle in
case of an error.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Devendra K Verma <devverma@amd.com>
[ Upstream commit 5e742de97c806a4048418237ef1283e7d71eaf4b ]
DMA Engine has support for the callback_result which provides
the status of the request and the residue. This helps in
determining the correct status of the request and in
efficient resource management of the request.
The 'callback_result' method is preferred over the deprecated
'callback' method.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit b63f008f395ca5f6bc89123db97440bdc19981c4 ]
According to Hardware Programming Guide for DSI PHY, the retime buffer
resync should be done after PLL clock users (byte_clk and intf_byte_clk)
are enabled. Downstream also does it as part of configuring the PLL.
Driver was only turning off the resync FIFO buffer, but never bringing it
on again.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit 5ddcb0cb9d10e6e70a68e0cb8f0b8e3a7eb8ccaf ]
Driver unconditionally saves current state on first init in
dsi_pll_7nm_init(), but does not save the VCO rate, only some of the
divider registers. The state is then restored during probe/enable via
msm_dsi_phy_enable() -> msm_dsi_phy_pll_restore_state() ->
dsi_7nm_pll_restore_state().
Restoring calls dsi_pll_7nm_vco_set_rate() with
pll_7nm->vco_current_rate=0, which basically overwrites existing rate of
VCO and messes with clock hierarchy, by setting frequency to 0 to clock
tree. This makes anyway little sense - VCO rate was not saved, so
should not be restored.
If PLL was not configured configure it to minimum rate to avoid glitches
and configuring entire in clock hierarchy to 0 Hz.

From: Antheas Kapenekakis <lkml@antheas.dev>
[ Upstream commit 9931e4be11f2129a20ffd908bc364598a63016f8 ]
Currently, having a valid panel_id match is required to use the quirk
system. For certain devices, we know that all SKUs need a certain quirk.
Therefore, allow not specifying ident by only checking for a match
if panel_id is non-zero.

------------------
From: Juraj Šarinay <juraj@sarinay.com>
[ Upstream commit 21f82062d0f241e55dd59eb630e8710862cc90b4 ]
An exchange with a NFC target must complete within NCI_DATA_TIMEOUT.
A delay of 700 ms is not sufficient for cryptographic operations on smart
cards. CardOS 6.0 may need up to 1.3 seconds to perform 256-bit ECDH
or 3072-bit RSA. To prevent brute-force attacks, passports and similar
documents introduce even longer delays into access control protocols
(BAC/PACE).
The timeout should be higher, but not too much. The expiration allows
us to detect that a NFC target has disappeared.

[ Upstream commit 46c1e7814d1c3310ef23c01ed1a582ef0c8ab1d2 ]
The .set_fmt callback should not write the new format directly do the
device, it should only store it and have it applied by .s_stream.
The .s_stream callback already calls adv7180_set_field_mode() so it's
safe to remove programming of the device and just store the format and
have .s_stream apply it.

[ Upstream commit 91c5d7c849273d14bc4bae1b92666bdb5409294a ]
The .querystd callback should not program the device with the detected
standard, it should only report the standard to user-space. User-space
may then use .s_std to set the standard, if it wants to use it.
All that is required of .querystd is to setup the auto detection of
standards and report its findings.
While at it add some documentation on why this can't happen while
streaming and improve the error handling using a scoped guard.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ramya Gnanasekar <ramya.gnanasekar@oss.qualcomm.com>
[ Upstream commit e53f8b12a21c2974b66fa8c706090182da06fff3 ]
Currently, when adding the 6 GHz Band Capabilities element, the channel
list of the wiphy is checked to determine if 6 GHz is supported for a given
virtual interface. However, in a multi-radio wiphy (e.g., one that has
both lower bands and 6 GHz combined), the wiphy advertises support for
all bands. As a result, the 6 GHz Band Capabilities element is incorrectly
included in mesh beacon and station's association request frames of
interfaces operating in lower bands, without verifying whether the
interface is actually operating in a 6 GHz channel.
Fix this by verifying if the interface operates on 6 GHz channel
before adding the element. Note that this check cannot be placed
directly in ieee80211_put_he_6ghz_cap() as the same function is used to
add probe request elements while initiating scan in which case the
interface may not be operating in any band's channel.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Wajdeczko <michal.wajdeczko@intel.com>
[ Upstream commit 2506af5f8109a387a5e8e9e3d7c498480b8033db ]
The GuC communication protocol allows GuC to send NO_RESPONSE_RETRY
reply message to indicate that due to some interim condition it can
not handle incoming H2G request and the host shall resend it.
But in some cases, due to errors, this unsatisfied condition might
be final and this could lead to endless retries as it was recently
seen on the CI:
[drm] GT0: PF: VF1 FLR didn't finish in 5000 ms (-ETIMEDOUT)
[drm] GT0: PF: VF1 resource sanitizing failed (-ETIMEDOUT)
[drm] GT0: PF: VF1 FLR failed!
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
To avoid such dangerous loops allow only limited number of retries
(for now 50) and add some delays (n * 5ms) to slow down the rate of
resending this repeated request.

After analysis, it appears this is because of the cond_resched()
call from __release_sock().
When current thread is yielding, while still holding the TCP socket lock,
it might regain the cpu after a very long time.
Other peer TLP/RTO is firing (multiple times) and packets are retransmit,
while the initial copy is waiting in the socket backlog or receive queue.
In this patch, I call cond_resched() only once every 16 packets.
Modern TCP stack now spends less time per packet in the backlog,
especially because ACK are no longer sent (commit 133c4c0d3717
"tcp: defer regular ACK while processing socket backlog")

From: Colin Foster <colin.foster@in-advantage.com>
[ Upstream commit 69777753a8919b0b8313c856e707e1d1fe5ced85 ]
When the EEPROM MAC is read by way of ADDRH, it can return all 0s the
first time. Subsequent reads succeed.
This is fully reproduceable on the Phytec PCM049 SOM.
Re-read the ADDRH when this behaviour is observed, in an attempt to
correctly apply the EEPROM MAC address.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ashish Kalra <ashish.kalra@amd.com>
[ Upstream commit 9be15fbfc6c5c89c22cf6e209f66ea43ee0e58bb ]
After a panic if SNP is enabled in the previous kernel then the kdump
kernel boots with IOMMU SNP enforcement still enabled.
IOMMU command buffers and event buffer registers remain locked and
exclusive to the previous kernel. Attempts to enable command and event
buffers in the kdump kernel will fail, as hardware ignores writes to
the locked MMIO registers as per AMD IOMMU spec Section 2.12.2.1.
Skip enabling command buffers and event buffers for kdump boot as they
are already enabled in the previous kernel.

From: Ashish Kalra <ashish.kalra@amd.com>
[ Upstream commit 8c571019d8a817b701888926529a5d7a826b947b ]
Since SEV or SNP may already be initialized in the previous kernel,
attempting to initialize them again in the kdump kernel can result
in SNP initialization failures, which in turn lead to IOMMU
initialization failures. Moreover, SNP/SEV guests are not run under a
kdump kernel, so there is no need to initialize SEV or SNP during
kdump boot.
Skip SNP and SEV INIT if doing kdump boot.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fangzhi Zuo <Jerry.Zuo@amd.com>
[ Upstream commit 12cdfb61b32a7be581ec5932e0b6a482cb098204 ]
[Why]
dm_mst_get_pbn_divider() returns value integer coming from
the cast from fixed point, but the casted integer will then be used
in dfixed_const to be multiplied by 4096. The cast from fixed point to integer
causes the calculation error becomes bigger when multiplied by 4096.
That makes the calculated pbn_div value becomes smaller than
it should be, which leads to the req_slot number becomes bigger.
Such error is getting reflected in 8k30 timing,
where the correct and incorrect calculated req_slot 62.9 Vs 63.1.
That makes the wrong calculation failed to light up 8k30
after a dock under HBR3 x 4.
[How]
Restore the accuracy by keeping the fraction part
calculated for the left shift operation.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vladimir Oltean <vladimir.oltean@nxp.com>
[ Upstream commit 6f616757dd306fce4b55131df23737732e347d8f ]
The "usxgmii" phy-mode that the Felix switch ports support on LS1028A is
not quite USXGMII, it is defined by the USXGMII multiport specification
document as 10G-QXGMII. It uses the same signaling as USXGMII, but it
multiplexes 4 ports over the link, resulting in a maximum speed of 2.5G
per port.
This change is needed in preparation for the lynx-10g SerDes driver on
LS1028A, which will make a more clear distinction between usxgmii
(supported on lane 0) and 10g-qxgmii (supported on lane 1). These
protocols have their configuration in different PCCR registers (PCCRB vs
PCCR9).
Continue parsing and supporting single-port-per-lane USXGMII when found
in the device tree as usual (because it works), but add support for
10G-QXGMII too. Using phy-mode = "10g-qxgmii" will be required when
modifying the device trees to specify a "phys" phandle to the SerDes
lane. The result when the "phys" phandle is present but the phy-mode is
wrong is undefined.
The only PHY driver in known use with this phy-mode, AQR412C, will gain
logic to transition from "usxgmii" to "10g-qxgmii" in a future change.
Prepare the driver by also setting PHY_INTERFACE_MODE_10G_QXGMII in
supported_interfaces when PHY_INTERFACE_MODE_USXGMII is there, to
prevent breakage with existing device trees.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Yufeng <chenyufeng@iie.ac.cn>
[ Upstream commit 87c5ff5615dc0a37167e8faf3adeeddc6f1344a3 ]
In the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadget
structure (pdev->gadget) was freed before its endpoints.
The endpoints are linked via the ep_list in the gadget structure.
Freeing the gadget first leaves dangling pointers in the endpoint list.
When the endpoints are subsequently freed, this results in a use-after-free.
Fix:
By separating the usb_del_gadget_udc() operation into distinct "del" and
"put" steps, cdnsp_gadget_free_endpoints() can be executed prior to the
final release of the gadget structure with usb_put_gadget().
A patch similar to bb9c74a5bd14("usb: dwc3: gadget: Free gadget structure
only after freeing endpoints").

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xion Wang <xion.wang@mediatek.com>
[ Upstream commit e28022873c0d051e980c4145f1965cab5504b498 ]
Currently, misc_deregister() uses list_del() to remove the device
from the list. After list_del(), the list pointers are set to
LIST_POISON1 and LIST_POISON2, which may help catch use-after-free bugs,
but does not reset the list head.
If misc_deregister() is called more than once on the same device,
list_empty() will not return true, and list_del() may be called again,
leading to undefined behavior.
Replace list_del() with list_del_init() to reinitialize the list head
after deletion. This makes the code more robust against double
deregistration and allows safe usage of list_empty() on the miscdevice
after deregistration.
[ Note, this seems to keep broken out-of-tree drivers from doing foolish
things. While this does not matter for any in-kernel drivers,
external drivers could use a bit of help to show them they shouldn't
be doing stuff like re-registering misc devices - gregkh ]

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Vasut <marek.vasut+renesas@mailbox.org>
[ Upstream commit d5f6bd3ee3f5048f272182dc91675c082773999e ]
Currently, the test allocates BAR sizes according to fixed table bar_size.
This does not work with controllers which have fixed size BARs that are
smaller than the requested BAR size. One such controller is Renesas R-Car
V4H PCIe controller, which has BAR4 size limited to 256 bytes, which is
much less than one of the BAR size, 131072 currently requested by this
test. A lot of controllers drivers in-tree have fixed size BARs, and they
do work perfectly fine, but it is only because their fixed size is larger
than the size requested by pci-epf-test.c
Adjust the test such that in case a fixed size BAR is detected, the fixed
BAR size is used, as that is the only possible option.
This helps with test failures reported as follows:
pci_epf_test pci_epf_test.0: requested BAR size is larger than fixed size
pci_epf_test pci_epf_test.0: Failed to allocate space for BAR4

[ Upstream commit bfbd5aa5347fbd11ade188b316b800bfb27d9e22 ]
The OmniVision OG01A1B image sensor is a monochrome sensor, it supports
8-bit and 10-bit RAW output formats only.
That said the planar greyscale Y8/Y10 media formats are more appropriate
for the sensor instead of the originally and arbitrary selected SGRBG one,
since there is no red, green or blue color components.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthieu Baerts (NGI0) <matttbe@kernel.org>
[ Upstream commit e2cda6343bfe459c3331db5afcd675ab333112dd ]
When many ADD_ADDR need to be sent, it can take some time to send each
of them, and create new subflows. Some CIs seem to occasionally have
issues with these tests, especially with "debug" kernels.
Two subtests will now run for a slightly longer time: the last two where
3 or more ADD_ADDR are sent during the test.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Wang <peter.wang@mediatek.com>
[ Upstream commit 91cad911edd1612ed28f5cfb2d4c53a8824951a5 ]
Resolve the issue of unbalanced IRQ enablement by setting the
'is_mcq_intr_enabled' flag after the first successful IRQ enablement.
Ensure proper tracking of the IRQ state and prevent potential mismatches
in IRQ handling.

From: Peter Wang <peter.wang@mediatek.com>
[ Upstream commit faac32d4ece30609f1a0930ca0ae951cf6dc1786 ]
Improve the recovery process for hibernation exit failures. Trigger the
error handler and break the suspend operation to ensure effective
recovery from hibernation errors. Activate the error handling mechanism
by ufshcd_force_error_recovery and scheduling the error handler work.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rohan G Thomas <rohan.g.thomas@altera.com>
[ Upstream commit deb105f49879dd50d595f7f55207d6e74dec34e6 ]
The 88e1510 PHY has an erratum where the phy downshift counter is not
cleared after phy being suspended(BMCR_PDOWN set) and then later
resumed(BMCR_PDOWN cleared). This can cause the gigabit link to
intermittently downshift to a lower speed.
Disabling and re-enabling the downshift feature clears the counter,
allowing the PHY to retry gigabit link negotiation up to the programmed
retry count times before downshifting. This behavior has been observed
on copper links.

From: Mario Limonciello (AMD) <superm1@kernel.org>
[ Upstream commit 6e490dea61b88aac9762c9f79a54aad4ea2e6cd1 ]
When compiled without CONFIG_VIDEO the architecture specific
implementations of video_is_primary_device() include prototypes and
assume that video-common.c will be linked. Guard against this so that the
fallback inline implementation that returns false will be used when
compiled without CONFIG_VIDEO.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Riesch <michael.riesch@collabora.com>
[ Upstream commit 8c7c19466c854fa86b82d2148eaa9bf0e6531423 ]
The driver for the Rockchip MIPI CSI-2 DPHY uses GRF register offset
value 0 to sort out undefined registers. However, the RK3588 CSIDPHY GRF
this offset is perfectly fine (in fact, register 0 is the only one in
this register file).
Introduce a boolean variable to indicate valid registers and allow writes
to register 0.

From: Rob Clark <robin.clark@oss.qualcomm.com>
[ Upstream commit 60e9f776b7932d67c88e8475df7830cb9cdf3154 ]
The upstream mesa copy of the GPU regs has shifted more things to reg64
instead of seperate 32b HI/LO reg32's. This works better with the "new-
style" c++ builders that mesa has been migrating to for a6xx+ (to better
handle register shuffling between gens), but it leaves the C builders
with missing _HI/LO builders.
So handle the special case of reg64, automatically generating the
missing _HI/LO builders.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakub Kicinski <kuba@kernel.org>
[ Upstream commit 15c068cb214d74a2faca9293b25f454242d0d65e ]
fcnal-test.sh already includes lib.sh, use relevant helpers
instead of sleeping. Replace sleep after starting nettest
as a server with wait_local_port_listen.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Qianfeng Rong <rongqianfeng@vivo.com>
[ Upstream commit ecba852dc9f4993f4f894ea1f352564560e19a3e ]
Change "ret" from u8 to int type in redrat3_enable_detector() to store
negative error codes or zero returned by redrat3_send_cmd() and
usb_submit_urb() - this better aligns with the coding standards and
maintains code consistency.
No effect on runtime.

[ Upstream commit c068ba9d3ded56cb1ba4d5135ee84bf8039bd563 ]
The test always returns success even if some tests were modified to
fail. Fix by converting the test to use the appropriate library
functions instead of using its own functions.

From: chenmiao <chenmiao.ku@gmail.com>
[ Upstream commit 9d0cb6d00be891586261a35da7f8c3c956825c39 ]
To ensure the proper functioning of the jump_label test module, this patch
adds support for the R_OR1K_32_PCREL relocation type for any modules. The
implementation calculates the PC-relative offset by subtracting the
instruction location from the target value and stores the result at the
specified location.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Westphal <fw@strlen.de>
[ Upstream commit db99b2f2b3e2cd8227ac9990ca4a8a31a1e95e56 ]
tcp reject code won't reply to a tcp reset.
But the icmp reject 'netdev' family versions will reply to icmp
dst-unreach errors, unlike icmp_send() and icmp6_send() which are used
by the inet family implementation (and internally by the REJECT target).
Check for the icmp(6) type and do not respond if its an unreachable error.
Without this, something like 'ip protocol icmp reject', when used
in a netdev chain attached to 'lo', cause a packet loop.
Same for two hosts that both use such a rule: each error packet
will be replied to.
Such situation persist until the (bogus) rule is amended to ratelimit or
checks the icmp type before the reject statement.
As the inet versions don't do this make the netdev ones follow along.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li RongQing <lirongqing@baidu.com>
[ Upstream commit 960550503965094b0babd7e8c83ec66c8a763b0b ]
The commit b2798ba0b876 ("KVM: X86: Choose qspinlock when dedicated
physical CPUs are available") states that when PV_DEDICATED=1
(vCPU has dedicated pCPU), qspinlock should be preferred regardless of
PV_UNHALT. However, the current implementation doesn't reflect this: when
PV_UNHALT=0, we still use virt_spin_lock() even with dedicated pCPUs.
This is suboptimal because:
1. Native qspinlocks should outperform virt_spin_lock() for dedicated
vCPUs irrespective of HALT exiting
2. virt_spin_lock() should only be preferred when vCPUs may be preempted
(non-dedicated case)
So reorder the PV spinlock checks to:
1. First handle dedicated pCPU case (disable virt_spin_lock_key)
2. Second check single CPU, and nopvspin configuration
3. Only then check PV_UNHALT support
This ensures we always use native qspinlock for dedicated vCPUs, delivering
pretty performance gains at high contention levels.

------------------
From: Daniel Palmer <daniel@thingy.jp>
[ Upstream commit 43adad382e1fdecabd2c4cd2bea777ef4ce4109e ]
When 8139too is probing and 8139TOO_PIO=y it will call pci_iomap_range()
and from there __pci_ioport_map() for the PCI IO space.
If HAS_IOPORT_MAP=n and NO_GENERIC_PCI_IOPORT_MAP=n, like it is on my
m68k config, __pci_ioport_map() becomes NULL, pci_iomap_range() will
always fail and the driver will complain it couldn't map the PIO space
and return an error.
NO_IOPORT_MAP seems to cover the case where what 8139too is trying
to do cannot ever work so make 8139TOO_PIO depend on being it false
and avoid creating an unusable driver.

tcp_recvmsg_dmabuf can export the following errors:
- EFAULT when linear copy fails
- ETOOSMALL when cmsg put fails
- ENODEV if one of the frags is readable
- ENOMEM on xarray failures
But they are all ignored and replaced by EFAULT in the caller
(tcp_recvmsg_locked). Expose real error to the userspace to
add more transparency on what specifically fails.
In non-devmem case (skb_copy_datagram_msg) doing `if (!copied)
copied=-EFAULT` is ok because skb_copy_datagram_msg can return only EFAULT.

[ Upstream commit dc2f650f7e6857bf384069c1a56b2937a1ee370d ]
netdev_WARN() uses WARN/WARN_ON to print a backtrace along with
file and line information. In this case, udp_tunnel_nic_register()
returning an error is just a failed operation, not a kernel bug.
udp_tunnel_nic_register() can fail due to a memory allocation
failure (kzalloc() or udp_tunnel_nic_alloc()).
This is a normal runtime error and not a kernel bug.
Replace netdev_WARN() with netdev_warn() accordingly.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antheas Kapenekakis <lkml@antheas.dev>
[ Upstream commit b595974b4afe0e171dd707da570964ff642742e3 ]
The Asus Z13 folio has a multitouch touchpad that needs to bind
to the hid-multitouch driver in order to work properly. So bind
it to the HID_GROUP_GENERIC group to release the touchpad and
move it to the bottom so that the comment applies to it.
While at it, change the generic KEYBOARD3 name to Z13_FOLIO.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sangwook Shin <sw617.shin@samsung.com>
[ Upstream commit df3c6e0b6d83450563d6266e1dacc7eaf25511f4 ]
Fix the issue of max_timeout being calculated larger than actual value.
The calculation result of freq / (S3C2410_WTCON_PRESCALE_MAX + 1) /
S3C2410_WTCON_MAXDIV is smaller than the actual value because the remainder
is discarded during the calculation process. This leads to a larger
calculated value for max_timeout compared to the actual settable value.
To resolve this issue, the order of calculations in the computation process
has been adjusted.

[ Upstream commit 9a23ea1f7558bdd3f8d2b35b1c2e16a2f9bf671e ]
Using the number of bytes in the request as DMA timeout is really
inconsistent, as large requests could possibly set a timeout of
hundreds of seconds.
Remove the per-channel timeout field and use a single, static DMA
timeout of 3 seconds for all requests.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
[ Upstream commit 09fefb24ed5e15f3b112f6c04b21a90ea23eaf8b ]
dw_pcie_edma_irq_verify() is supposed to verify the eDMA IRQs in devicetree
by fetching them using either 'dma' or 'dmaX' IRQ names. Former is used
when the platform uses a single IRQ for all eDMA channels and latter is
used when the platform uses separate IRQ per channel. But currently,
dw_pcie_edma_irq_verify() bails out early if edma::nr_irqs is 1, i.e., when
a single IRQ is used. This gives an impression that the driver could work
with any single IRQ in devicetree, not necessarily with name 'dma'.
But dw_pcie_edma_irq_vector(), which actually requests the IRQ, does
require the single IRQ to be named as 'dma'. So this creates inconsistency
between dw_pcie_edma_irq_verify() and dw_pcie_edma_irq_vector().
Thus, to fix this inconsistency, make sure dw_pcie_edma_irq_verify() also
verifies the single IRQ name by removing the bail out code.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yunseong Kim <ysk@kzalloc.com>
[ Upstream commit 2b0dc40ac6ca16ee0c489927f4856cf9cd3874c7 ]
payload_size field of the request header is incorrectly calculated using
sizeof(req). Since 'req' is a pointer (struct hsti_request *), sizeof(req)
returns the size of the pointer itself (e.g., 8 bytes on a 64-bit system),
rather than the size of the structure it points to. This leads to an
incorrect payload size being sent to the Platform Security Processor (PSP),
potentially causing the HSTI query command to fail.
Fix this by using sizeof(*req) to correctly calculate the size of the
struct hsti_request.

during entropy evaluation, if the generated samples fail

and a second set of samples will be generated and tested.
the entropy delay interval should be doubled before performing the

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yafang Shao <laoar.shao@gmail.com>
[ Upstream commit 66048f8b3cc7e462953c04285183cdee43a1cb89 ]
During recent testing with the netem qdisc to inject delays into TCP
traffic, we observed that our CLS BPF program failed to function correctly
due to incorrect classid retrieval from task_get_classid(). The issue
manifests in the following call stack:
bpf_get_cgroup_classid+5
cls_bpf_classify+507
__tcf_classify+90
tcf_classify+217
__dev_queue_xmit+798
bond_dev_queue_xmit+43
__bond_start_xmit+211
bond_start_xmit+70
dev_hard_start_xmit+142
sch_direct_xmit+161
__qdisc_run+102 <<<<< Issue location
__dev_xmit_skb+1015
__dev_queue_xmit+637
neigh_hh_output+159
ip_finish_output2+461
__ip_finish_output+183
ip_finish_output+41
ip_output+120
ip_local_out+94
__ip_queue_xmit+394
ip_queue_xmit+21
__tcp_transmit_skb+2169
tcp_write_xmit+959
__tcp_push_pending_frames+55
tcp_push+264
tcp_sendmsg_locked+661
tcp_sendmsg+45
inet_sendmsg+67
sock_sendmsg+98
sock_write_iter+147
vfs_write+786
ksys_write+181
__x64_sys_write+25
do_syscall_64+56
entry_SYSCALL_64_after_hwframe+100
The problem occurs when multiple tasks share a single qdisc. In such cases,
__qdisc_run() may transmit skbs created by different tasks. Consequently,
task_get_classid() retrieves an incorrect classid since it references the
current task's context rather than the skb's originating task.
Given that dev_queue_xmit() always executes with bh disabled, we can use
softirq_count() instead to obtain the correct classid.
The simple steps to reproduce this issue:
1. Add network delay to the network interface:
such as: tc qdisc add dev bond0 root netem delay 1.5ms
2. Build two distinct net_cls cgroups, each with a network-intensive task
3. Initiate parallel TCP streams from both tasks to external servers.
Under this specific condition, the issue reliably occurs. The kernel
eventually dequeues an SKB that originated from Task-A while executing in
the context of Task-B.
It is worth noting that it will change the established behavior for a
slightly different scenario:
<sock S is created by task A>
<class ID for task A is changed>
<skb is created by sock S xmit and classified>
prior to this patch the skb will be classified with the 'new' task A
classid, now with the old/original one. The bpf_get_cgroup_classid_curr()
function is a more appropriate choice for this case.

From: Quan Zhou <quan.zhou@mediatek.com>
[ Upstream commit 25ef5b5d02ac03fe8dd91cf25bd011a570fbeba2 ]
Enable 160MHz beamformee support on mt7922 by updating HE capability
element configuration. Previously, only 160MHz channel width was set,
but beamformee for 160MHz was not properly advertised. This patch
adds BEAMFORMEE_MAX_STS_ABOVE_80MHZ_4 capability to allow devices
to utilize 160MHz BW for beamforming.
Tested by connecting to 160MHz-bandwidth beamforming AP and verified
HE capability.

[ Upstream commit c7c682100cec97b699fe24b26d89278fd459cc84 ]
mt76_eeprom_override has of_get_mac_address, which can return
-EPROBE_DEFER if the nvmem driver gets loaded after mt76 for some
reason.
Make sure this gets passed to probe so that nvmem mac overrides always
work.

------------------
From: John Keeping <jkeeping@inmusicbrands.com>
[ Upstream commit 84973249011fda3ff292f83439a062fec81ef982 ]
If multiple instances of this driver are instantiated and try to send
concurrently then the single static buffer snd_serial_generic_tx_work()
will cause corruption in the data output.
Move the buffer into the per-instance driver data to avoid this.

From: Mario Limonciello <Mario.Limonciello@amd.com>
[ Upstream commit 5e76bc677cb7c92b37d8bc66bb67a18922895be2 ]
[Why]
fill_stream_properties_from_drm_display_mode() will not configure pixel
encoding to YCBCR422 when the DRM color format supports YCBCR422 but not
YCBCR420 or YCBCR4444. Instead it will fallback to RGB.
[How]
Add support for YCBCR422 in pixel encoding mapping.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Timur Kristóf <timur.kristof@gmail.com>
[ Upstream commit 489f0f600ce2c0dae640df9035e1d82677d2580f ]
When the EDID has the HDMI bit, we should simply select
the HDMI signal type even on DVI ports.
For reference see, the legacy amdgpu display code:
amdgpu_atombios_encoder_get_encoder_mode
which selects ATOM_ENCODER_MODE_HDMI for the same case.
This commit fixes DVI connectors to work with DVI-D/HDMI
adapters so that they can now produce output over these
connectors for HDMI monitors with higher bandwidth modes.
With this change, even HDMI audio works through DVI.
For testing, I used a CAA-DMDHFD3 DVI-D/HDMI adapter
with the following GPUs:
Tahiti (DCE 6) - DC can now output 4K 30 Hz over DVI
Polaris 10 (DCE 11.2) - DC can now output 4K 60 Hz over DVI

From: Timur Kristóf <timur.kristof@gmail.com>
[ Upstream commit 043c87d7d56e135393f8aab927148096e2d17589 ]
DCE 6 was not advertised as being able to support VRR,
so let's mark it as unsupported for now.
The VRR implementation in amdgpu_dm depends on the VUPDATE
interrupt which is not registered for DCE 6.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xi Ruoyao <xry111@xry111.site>
[ Upstream commit c97a7dccb3ed680031011cfc1457506e6de49c9a ]
dml21_map_dc_state_into_dml_display_cfg calls (the call is usually
inlined by the compiler) populate_dml21_surface_config_from_plane_state
and populate_dml21_plane_config_from_plane_state which may use FPU. In
a x86-64 build:
$ objdump --disassemble=dml21_map_dc_state_into_dml_display_cfg \
> drivers/gpu/drm/amd/display/dc/dml2/dml21/dml21_translation_helper.o |
> grep %xmm -c
63
Thus it needs to be guarded with DC_FP_START. But we must note that the
current code quality of the in-kernel FPU use in AMD dml2 is very much
problematic: we are actually calling DC_FP_START in dml21_wrapper.c
here, and this translation unit is built with CC_FLAGS_FPU. Strictly
speaking this does not make any sense: with CC_FLAGS_FPU the compiler is
allowed to generate FPU uses anywhere in the translated code, perhaps
out of the DC_FP_START guard. This problematic pattern also occurs in
at least dml2_wrapper.c, dcn35_fpu.c, and dcn351_fpu.c. Thus we really
need a careful audit and refactor for the in-kernel FPU uses, and this
patch is simply whacking a mole. However per the reporter, whacking
this mole is enough to make a 9060XT "just work."

From: Jakub Kicinski <kuba@kernel.org>
[ Upstream commit f3b52167a0cb23b27414452fbc1278da2ee884fc ]
Driver authors often forget to add GFP_NOWARN for page allocation
from the datapath. This is annoying to users as OOMs are a fact
of life, and we pretty much expect network Rx to hit page allocation
failures during OOM. Make page pool add GFP_NOWARN for ATOMIC allocations
by default.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello (AMD) <superm1@kernel.org>
[ Upstream commit 7d62beb102d6fa9a4e5e874be7fbf47a62fcc4f6 ]
Dell systems utilize an EC-based touchpad emulation when the ACPI
touchpad _DSM is not invoked. This emulation acts as a secondary
master on the I2C bus, designed for scenarios where the I2C touchpad
driver is absent, such as in BIOS menus. Typically, loading the
i2c-hid module triggers the _DSM at initialization, disabling the
EC-based emulation.
However, if the i2c-hid module is missing from the boot kernel
used for hibernation snapshot restoration, the _DSM remains
uncalled, resulting in dual masters on the I2C bus and
subsequent arbitration errors. This issue arises when i2c-hid
resides in the rootfs instead of the kernel or initramfs.
To address this, switch from using the SYSTEM_SLEEP_PM_OPS()
macro to dedicated callbacks, introducing a specific
callback for restoring the S4 image. This callback ensures
the _DSM is invoked.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Harrison <John.C.Harrison@Intel.com>
[ Upstream commit 3b09b11805bfee32d5a0000f5ede42c07237a6c4 ]
Due to multiple explosion issues in the early days of the Xe driver,
the GuC load was hacked to never return a failure. That prevented
kernel panics and such initially, but now all it achieves is creating
more confusing errors when the driver tries to submit commands to a
GuC it already knows is not there. So fix that up.
As a stop-gap and to help with debug of load failures due to invalid
GuC init params, a wedge call had been added to the inner GuC load
function. The reason being that it leaves the GuC log accessible via
debugfs. However, for an end user, simply aborting the module load is
much cleaner than wedging and trying to continue. The wedge blocks
user submissions but it seems that various bits of the driver itself
still try to submit to a dead GuC and lots of subsequent errors occur.
And with regards to developers debugging why their particular code
change is being rejected by the GuC, it is trivial to either add the
wedge back in and hack the return code to zero again or to just do a
GuC log dump to dmesg.
v2: Add support for error injection testing and drop the now redundant
wedge call.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian König <christian.koenig@amd.com>
[ Upstream commit d7ddcf921e7d0d8ebe82e89635bc9dc26ba9540d ]
Gang submission means that the kernel driver guarantees that multiple
submissions are executed on the HW at the same time on different engines.
Background is that those submissions then depend on each other and each
can't finish stand alone.
SRIOV now uses world switch to preempt submissions on the engines to allow
sharing the HW resources between multiple VFs.
The problem is now that the SRIOV world switch can't know about such inter
dependencies and will cause a timeout if it waits for a partially running
gang submission.
To conclude SRIOV and gang submissions are fundamentally incompatible at
the moment. For now just disable them.

[ Upstream commit d3f7457da7b9527a06dbcbfaf666aa51ac2eeb53 ]
The selftests 'make clean' does not clean the net/lib because it only
processes $(TARGETS) and ignores $(INSTALL_DEP_TARGETS). This leaves
compiled objects in net/lib after cleaning, requiring manual cleanup.
Include $(INSTALL_DEP_TARGETS) in clean target to ensure net/lib
dependency is properly cleaned.

From: Justin Tee <justin.tee@broadcom.com>
[ Upstream commit a4809b98eb004fcbf7c4d45eb5a624d1c682bb73 ]
In lpfc_cleanup, there is an extraneous nlp_put for NPIV ports on the
F_Port_Ctrl ndlp object. In cases when an ABTS is issued, the
outstanding kref is needed for when a second XRI_ABORTED CQE is
received. The final kref for the ndlp is designed to be decremented in
lpfc_sli4_els_xri_aborted instead. Also, add a new log message to allow
for future diagnostics when debugging related issues.

------------------
From: Justin Tee <justin.tee@broadcom.com>
[ Upstream commit 2bf81856a403c92a4ce375288f33fba82ca2ccc6 ]
There is a timing race condition when a PRLI may be sent on the wire
before PLOGI_ACC in Point to Point topology. Fix by deferring REG_RPI
mbox completion handling to after PLOGI_ACC's CQE completion. Because
the discovery state machine only sends PRLI after REG_RPI mbox
completion, PRLI is now guaranteed to be sent after PLOGI_ACC.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Forest Crossman <cyrozap@gmail.com>
[ Upstream commit 368ed48a5ef52e384f54d5809f0a0b79ac567479 ]
The usbmon binary interface currently truncates captures of large
transfers from higher-speed USB devices. Because a single event capture
is limited to one-fifth of the total buffer size, the current maximum
size of a captured URB is around 240 KiB. This is insufficient when
capturing traffic from modern devices that use transfers of several
hundred kilobytes or more, as truncated URBs can make it impossible for
user-space USB analysis tools like Wireshark to properly defragment and
reassemble higher-level protocol packets in the captured data.
The root cause of this issue is the 1200 KiB BUFF_MAX limit, which has
not been changed since the binary interface was introduced in 2006.
To resolve this issue, this patch increases BUFF_MAX to 64 MiB. The
original comment for BUFF_MAX based the limit's calculation on a
saturated 480 Mbit/s bus. Applying the same logic to a modern USB 3.2
Gen 2×2 20 Gbit/s bus (~2500 MB/s over a 20ms window) indicates the
buffer should be at least 50 MB. The new limit of 64 MiB covers that,
plus a little extra for any overhead.
With this change, both users and developers should now be able to debug
and reverse engineer modern USB devices even when running unmodified
distro kernels.
Please note that this change does not affect the default buffer size. A
larger buffer is only allocated when a user explicitly requests it via
the MON_IOCT_RING_SIZE ioctl, so the change to the maximum buffer size
should not unduly increase memory usage for users that don't
deliberately request a larger buffer.

[ Upstream commit 41cf11946b9076383a2222bbf1ef57d64d033f66 ]
Allow autosuspend to be used by xhci plat device. For Qualcomm SoCs,
when in host mode, it is intended that the controller goes to suspend
state to save power and wait for interrupts from connected peripheral
to wake it up. This is particularly used in cases where a HID or Audio
device is connected. In such scenarios, the usb controller can enter
auto suspend and resume action after getting interrupts from the
connected device.

From: wangzijie <wangzijie1@honor.com>
[ Upstream commit 23361bd54966b437e1ed3eb1a704572f4b279e58 ]
When we get wrong extent info data, and look up extent_node in rb tree,
it will cause infinite loop (CONFIG_F2FS_CHECK_FS=n). Avoiding this by
return NULL and print some kernel messages in that case.

From: Zong-Zhe Yang <kevin_yang@realtek.com>
[ Upstream commit bc2a5a12fa6259e190c7edb03e63b28ab480101b ]
Logically before a waiting side which has already timed out turns the
atomic status back to idle, a completing side could still pass atomic
condition and call complete. It will make the following H2C commands,
waiting C2H events, get a completion unexpectedly early. Hence, renew
a completion for each H2C command waiting a C2H event.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Neronin <niklas.neronin@linux.intel.com>
[ Upstream commit 719de070f764e079cdcb4ddeeb5b19b3ddddf9c1 ]
Add xhci support for PCI hosts that have zero USB3 ports.
Avoid creating a shared Host Controller Driver (HCD) when there is only
one root hub. Additionally, all references to 'xhci->shared_hcd' are now
checked before use.
Only xhci-pci.c requires modification to accommodate this change, as the
xhci core already supports configurations with zero USB3 ports. This
capability was introduced when xHCI Platform and MediaTek added support
for zero USB3 ports.

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 9fba1eb39e2f74d2002c5cbcf1d4435d37a4f752 ]
Add READ_ONCE() annotations because np->rxpmtu can be changed
while udpv6_recvmsg() and rawv6_recvmsg() read it.
Since this is a very rarely used feature, and that udpv6_recvmsg()
and rawv6_recvmsg() read np->rxopt anyway, change the test order
so that np->rxpmtu does not need to be in a hot cache line.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Dumitrescu <vdumitrescu@nvidia.com>
[ Upstream commit 42f993d3439827c4959ea77e60620d7ebfb3a477 ]
Currently, all master upper netdevices (e.g., bond, VRF) are treated
equally.
When a VRF netdevice is used over an IPoIB netdevice, the expected
netdev resolution is on the lower IPoIB device which has the IP address
assigned to it and not the VRF device.
The rdma_cm module (CMA) tries to match incoming requests to a
particular netdevice. When successful, it also validates that the return
path points to the same device by performing a routing table lookup.
Currently, the former would resolve to the VRF netdevice, while the
latter to the correct lower IPoIB netdevice, leading to failure in
rdma_cm.
Improve this by ignoring the VRF master netdevice, if it exists, and
instead return the lower IPoIB device.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shaurya Rane <ssrane_b23@ee.vjti.ac.in>
[ Upstream commit 300b072df72694ea330c4c673c035253e07827b8 ]
The transaction manager initialization in txInit() was not properly
initializing TxBlock[0].waitor waitqueue, causing a crash when
txEnd(0) is called on read-only filesystems.
When a filesystem is mounted read-only, txBegin() returns tid=0 to
indicate no transaction. However, txEnd(0) still gets called and
tries to access TxBlock[0].waitor via tid_to_tblock(0), but this
waitqueue was never initialized because the initialization loop
started at index 1 instead of 0.
This causes a 'non-static key' lockdep warning and system crash:
INFO: trying to register non-static key in txEnd
Fix by ensuring all transaction blocks including TxBlock[0] have
their waitqueues properly initialized during txInit().

[ Upstream commit cc9a8e238e42c1f43b98c097995137d644b69245 ]
kcalloc() may fail. When WS is non-zero and allocation fails, ectx.ws
remains NULL while ectx.ws_size is set, leading to a potential NULL
pointer dereference in atom_get_src_int() when accessing WS entries.
Return -ENOMEM on allocation failure to avoid the NULL dereference.

[ Upstream commit 60f887b1290b43a4f5a3497982a725687b193fa4 ]
When a PHY is halted (e.g. `ip link set dev lan2 down`), several
fields in struct phy_device may still reflect the last active
connection. This leads to ethtool showing stale values even though
the link is down.
Reset selected fields in _phy_state_machine() when transitioning
to PHY_HALTED and the link was previously up:
- speed/duplex -> UNKNOWN, but only in autoneg mode (in forced mode
these fields carry configuration, not status)
- master_slave_state -> UNKNOWN if previously supported
- mdix -> INVALID (state only, same meaning as "unknown")
- lp_advertising -> always cleared
The cleanup is skipped if the PHY is in PHY_ERROR state, so the
last values remain available for diagnostics.

From: Vivek Pernamitta <quic_vpernami@quicinc.com>
[ Upstream commit aa1a0e93ed21a06acb7ca9d4a4a9fce75ea53d0c ]
Allow mhi_sync_power_up to handle SYS_ERR during power-up, reboot,
or recovery. This is to avoid premature exit when MHI_PM_IN_ERROR_STATE is
observed during above mentioned system states.
To achieve this, treat SYS_ERR as a valid state and let its handler process
the error and queue the next transition to Mission Mode instead of aborting
early.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Seyediman Seyedarab <ImanDevel@gmail.com>
[ Upstream commit 75c02a037609f34db17e91be195cedb33b61bae0 ]
snprintf() returns the number of bytes that would have been written, not
the number actually written. Using this for offset tracking can cause
buffer overruns if truncation occurs.
Replace snprintf() with scnprintf() to ensure the offset stays within
bounds.
Since scnprintf() never returns a negative value, and zero is not possible
in this context because 'bytes' starts at 0 and 'size - bytes' is
DEBUG_BUFFER_SIZE in the first call, which is large enough to hold the
string literals used, the return value is always positive. An integer
overflow is also completely out of reach here due to the small and fixed
buffer size. The error check in latency_show_one() is therefore
unnecessary. Remove it and make dmar_latency_snapshot() return void.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Loic Poulain <loic.poulain@oss.qualcomm.com>
[ Upstream commit 487e8a8c3421df0af3707e54c7e069f1d89cbda7 ]
It appears that not all hardware/firmware implementations support
group key deletion correctly, which can lead to connection hangs
and deauthentication following GTK rekeying (delete and install).
To avoid this issue, instead of attempting to delete the key using
the special WMI_CIPHER_NONE value, we now replace the key with an
invalid (random) value.
This behavior has been observed with WCN39xx chipsets.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brahmajit Das <listout@listout.xyz>
[ Upstream commit 99e9c5ffbbee0f258a1da4eadf602b943f8c8300 ]
Variable idx is set in the loop, but is never used resulting in dead
code. Building with GCC 16, which enables
-Werror=unused-but-set-parameter= by default results in build error.
This patch removes the idx parameter, since all the callers of the
fm10k_unbind_hw_stats_q as 0 as idx anyways.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: ChunHao Lin <hau@realtek.com>
[ Upstream commit bf7154ffb1c65a201906296a9d3eb22e9daa5ffc ]
EEE speed down means speed down MAC MCU clock. It is not from spec.
It is kind of Realtek specific power saving feature. But enable it
may cause some issues, like packet drop or interrupt loss. Different
hardware may have different issues.
EEE speed down ratio (mac ocp 0xe056[7:4]) is used to set EEE speed
down rate. The larger this value is, the more power can save. But it
actually save less power then we expected. And, as mentioned above,
will impact compatibility. So set it to 1 (mac ocp 0xe056[7:4] = 0)
, which means not to speed down, to improve compatibility.

[ Upstream commit 49a6c160ad4812476f8ae1a8f4ed6d15adfa6c09 ]
cdns_pcie::ops might not be populated by all the Cadence glue drivers. This
is going to be true for the upcoming Sophgo platform which doesn't set the
ops.
Hence, add a check to prevent NULL pointer dereference.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Mastro <amastro@fb.com>
[ Upstream commit 16df67f2189a71a8310bcebddb87ed569e8352be ]
The two implementers of vfio_device_ops.device_feature,
vfio_cdx_ioctl_feature and vfio_pci_core_ioctl_feature, return
-ENOTTY in the fallthrough case when the feature is unsupported. For
consistency, the base case, vfio_ioctl_device_feature, should do the
same when device_feature == NULL, indicating an implementation has no
feature extensions.

From: Weili Qian <qianweili@huawei.com>
[ Upstream commit 85acd1b26b8f5b838887dc965dc3aa2c0253f4d1 ]
Before the device reset, although the driver has set the queue
status to intercept doorbells sent by the task process, the reset
thread is isolated from the user-mode task process, so the task process
may still send doorbells. Therefore, before the reset, the queue is
directly invalidated, and the device directly discards the doorbells
sent by the process.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@amd.com>
[ Upstream commit 299fad4133677b845ce962f78c9cf75bded63f61 ]
When a device is surprise-removed (e.g., due to a dock unplug), the PCI
core unconfigures all downstream devices and sets their error state to
pci_channel_io_perm_failure. This marks them as disconnected via
pci_dev_is_disconnected().
During device removal, the runtime PM framework may attempt to resume the
device to D0 via pm_runtime_get_sync(), which calls into pci_power_up().
Since the device is already disconnected, this resume attempt is
unnecessary and results in a predictable errors like this, typically when
undocking from a TBT3 or USB4 dock with PCIe tunneling:
pci 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
Avoid powering up disconnected devices by checking their status early in
pci_power_up() and returning -EIO.

From: David Yang <mmyangfl@gmail.com>
[ Upstream commit 50d51cef555ee42fe47dd51b71366a77895e5f0b ]
Quoted from musl wiki:
GNU getopt permutes argv to pull options to the front, ahead of
non-option arguments. musl and the POSIX standard getopt stop
processing options at the first non-option argument with no
permutation.
Thus these scripts stop working on musl since non-option arguments for
tools using getopt() (in this case, (ar)ping) do not always come last.
Fix it by reordering arguments.

From: Stephan Gerhold <stephan.gerhold@linaro.org>
[ Upstream commit 54898664e1eb6b5b3e6cdd9343c6eb15da776153 ]
A remoteproc could theoretically signal handover twice. This is unexpected
and would break the reference counting for the handover resources (power
domains, clocks, regulators, etc), so add a check to prevent that from
happening.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bastien Curutchet <bastien.curutchet@bootlin.com>
[ Upstream commit a0b977a3d19368b235f2a6c06e800fb25452029b ]
At reset, the KSZ8463 uses a strap-based configuration to set SPI as
bus interface. SPI is the only bus supported by the driver. If the
required pull-ups/pull-downs are missing (by mistake or by design to
save power) the pins may float and the configuration can go wrong
preventing any communication with the switch.
Introduce a ksz8463_configure_straps_spi() function called during the
device reset. It relies on the 'straps-rxd-gpios' OF property and the
'reset' pinmux configuration to enforce SPI as bus interface.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lo-an Chen <lo-an.chen@amd.com>
[ Upstream commit f082daf08f2ff313bdf9cf929a28f6d888117986 ]
[Why]
Driver does not pick up and save vbios's clocks during init clocks,
the dispclk in clk_mgr will keep 0 until the first update clocks.
In some cases, OS changes the timing in the second set mode
(lower the pixel clock), causing the driver to lower the dispclk
in prepare bandwidth, which is illegal and causes grey screen.
[How]
1. Dump and save the vbios's clocks, and init the dispclk in
dcn314_init_clocks.
2. Fix the condition in dcn314_update_clocks, regarding a 0kHz value.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Melissa Wen <mwen@igalia.com>
[ Upstream commit 51cb93aa0c4a9bb126b76f6e9fd640d88de25cee ]
Don't update DC stream color components during atomic check. The driver
will continue validating the new CRTC color state but will not change DC
stream color components. The DC stream color state will only be
programmed at commit time in the `atomic_setup_commit` stage.
It fixes gamma LUT loss reported by KDE users when changing brightness
quickly or changing Display settings (such as overscan) with nightlight
on and HDR. As KWin can do a test commit with color settings different
from those that should be applied in a non-test-only commit, if the
driver changes DC stream color state in atomic check, this state can be
eventually HW programmed in commit tail, instead of the respective state
set by the non-blocking commit.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anthony Iliopoulos <ailiop@suse.com>
[ Upstream commit bf75ad096820fee5da40e671ebb32de725a1c417 ]
When client initialization goes through server trunking discovery, it
schedules the state manager and then sleeps waiting for nfs_client
initialization completion.
The state manager can fail during state recovery, and specifically in
lease establishment as nfs41_init_clientid() will bail out in case of
errors returned from nfs4_proc_create_session(), without ever marking
the client ready. The session creation can fail for a variety of reasons
e.g. during backchannel parameter negotiation, with status -EINVAL.
The error status will propagate all the way to the nfs4_state_manager
but the client status will not be marked, and thus the mount process
will remain blocked waiting.
Fix it by adding -EINVAL error handling to nfs4_state_manager().

Theoretically it's an oopsable race, but I don't believe one can manage
to hit it on real hardware; might become doable on a KVM, but it still
won't be easy to attack.
Anyway, it's easy to deal with - since xdr_encode_hyper() is just a call of
put_unaligned_be64(), we can put that under ->d_lock and be done with that.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Petr Machata <petrm@nvidia.com>
[ Upstream commit cd9a9562b2559973aa1b68c3af63021a2c5fd022 ]
Currently, after the bridge is created, the FDB does not hold an FDB entry
for the bridge MAC on VLAN 0:
# ip link add name br up type bridge
# ip -br link show dev br
br UNKNOWN 92:19:8c:4e:01:ed <BROADCAST,MULTICAST,UP,LOWER_UP>
# bridge fdb show | grep 92:19:8c:4e:01:ed
92:19:8c:4e:01:ed dev br vlan 1 master br permanent
Later when the bridge MAC is changed, or in fact when the address is given
during netdevice creation, the entry appears:
# ip link add name br up address 00:11:22:33:44:55 type bridge
# bridge fdb show | grep 00:11:22:33:44:55
00:11:22:33:44:55 dev br vlan 1 master br permanent
00:11:22:33:44:55 dev br master br permanent
However when the bridge address is set by the user to the current bridge
address before the first port is enslaved, none of the address handlers
gets invoked, because the address is not actually changed. The address is
however marked as NET_ADDR_SET. Then when a port is enslaved, the address
is not changed, because it is NET_ADDR_SET. Thus the VLAN 0 entry is not
added, and it has not been added previously either:
# ip link add name br up type bridge
# ip -br link show dev br
br UNKNOWN 7e:f0:a8:1a:be:c2 <BROADCAST,MULTICAST,UP,LOWER_UP>
# ip link set dev br addr 7e:f0:a8:1a:be:c2
# ip link add name v up type veth
# ip link set dev v master br
# ip -br link show dev br
br UNKNOWN 7e:f0:a8:1a:be:c2 <BROADCAST,MULTICAST,UP,LOWER_UP>
# bridge fdb | grep 7e:f0:a8:1a:be:c2
7e:f0:a8:1a:be:c2 dev br vlan 1 master br permanent
Then when the bridge MAC is used as DMAC, and br_handle_frame_finish()
looks up an FDB entry with VLAN=0, it doesn't find any, and floods the
traffic instead of passing it up.
Fix this by simply adding the VLAN 0 FDB entry for the bridge itself always
on netdevice creation. This also makes the behavior consistent with how
ports are treated: ports always have an FDB entry for each member VLAN as
well as VLAN 0.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alok Tiwari <alok.a.tiwari@oracle.com>
[ Upstream commit 072fdd4b0be9b9051bdf75f36d0227aa705074ba ]
The fc_ct_ms_fill() helper currently formats the OS name and version
into entry->value using "%s v%s". Since init_utsname()->sysname and
->release are unbounded strings, snprintf() may attempt to write more
than FC_FDMI_HBA_ATTR_OSNAMEVERSION_LEN bytes, triggering a
-Wformat-truncation warning with W=1.
In file included from drivers/scsi/libfc/fc_elsct.c:18:
drivers/scsi/libfc/fc_encode.h: In function ‘fc_ct_ms_fill.constprop’:
drivers/scsi/libfc/fc_encode.h:359:30: error: ‘%s’ directive output may

and 126 [-Werror=format-truncation=]

| ~~~~~~~~~~~~~~~~~~~~~~~~
361 | init_utsname()->release);
| ~~~~~~~~~~~~~~~~~~~~~~~~
Fix this by using "%.62s v%.62s", which ensures sysname and release are
truncated to fit within the 128-byte field defined by
FC_FDMI_HBA_ATTR_OSNAMEVERSION_LEN.

------------------
From: Ranjan Kumar <ranjan.kumar@broadcom.com>
[ Upstream commit 4be7599d6b27bade41bfccca42901b917c01c30c ]
Add handling for MPI26_SAS_NEG_LINK_RATE_22_5 in
_transport_convert_phy_link_rate(). This maps the new 22.5 Gbps
negotiated rate to SAS_LINK_RATE_22_5_GBPS, to get correct PHY link
speeds.

From: Tomer Tayar <tomer.tayar@intel.com>
[ Upstream commit 9f5067531c9b79318c4e48a933cb2694f53f3de2 ]
EFAULT is currently returned if less than requested user pages are
pinned. This value means a "bad address" which might be confusing to
the user, as the address of the given user memory is not necessarily
"bad".
Modify the return value to ENOMEM, as "out of memory" is more suitable
in this case.

Dirty state can occur when the host VM undergoes a reset while the
device does not. In such a case, the driver must reset the device before
it can be used again. As part of this reset, the device capabilities
are zeroed. Therefore, the driver must read the Preboot status again to
learn the Preboot state, capabilities, and security configuration.

Looks good for 6.12-stable. The backport correctly re-reads the preboot
status after recovering from a dirty state, restoring accurate capability
and security information following a VM-only reset.
Thanks,

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Moti Haimovski <moti.haimovski@intel.com>
[ Upstream commit 513024d5a0e34fd34247043f1876b6138ca52847 ]
When IOMMU is enabled, dma_alloc_coherent() with GFP_USER may return
addresses from the vmalloc range. If such an address is mapped without
VM_MIXEDMAP, vm_insert_page() will trigger a BUG_ON due to the
VM_PFNMAP restriction.
Fix this by checking for vmalloc addresses and setting VM_MIXEDMAP
in the VMA before mapping. This ensures safe mapping and avoids kernel
crashes. The memory is still driver-allocated and cannot be accessed
directly by userspace.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Julian Sun <sunjunchao@bytedance.com>
[ Upstream commit 46e75c56dfeafb6756773b71cabe187a6886859a ]
The following code paths may result in high latency or even task hangs:
1. fastcommit io is throttled by wbt.
2. jbd2_fc_wait_bufs() might wait for a long time while
JBD2_FAST_COMMIT_ONGOING is set in journal->flags, and then
jbd2_journal_commit_transaction() waits for the
JBD2_FAST_COMMIT_ONGOING bit for a long time while holding the write
lock of j_state_lock.
3. start_this_handle() waits for read lock of j_state_lock which
results in high latency or task hang.
Given the fact that ext4_fc_commit() already modifies the current
process' IO priority to match that of the jbd2 thread, it should be
reasonable to match jbd2's IO submission flags as well.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Olivier Moysan <olivier.moysan@foss.st.com>
[ Upstream commit 27fa1a8b2803dfd88c39f03b0969c55f667cdc43 ]
The mclk direction now needs to be specified in endpoint node with
"system-clock-direction-out" property. However some calls to the
set_sysclk callback, related to CPU DAI clock, result in unbalanced
calls to clock API.
The set_sysclk callback in STM32 SAI driver is intended only for mclk
management. So it is relevant to ensure that calls to set_sysclk are
related to mclk only.
Since the master clock is handled only at runtime, skip the calls to
set_sysclk in the initialization phase.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Primoz Fiser <primoz.fiser@norik.com>
[ Upstream commit 733a763dd8b3ac2858dd238a91bb3a2fdff4739e ]
The problem of having class-D initialization sequence in probe using
regmap_register_patch() is that it will do hardware register writes
immediately after being called as it bypasses regcache. Afterwards, in
aic3x_init() we also perform codec soft reset, rendering class-D init
sequence pointless. This issue is even more apparent when using reset
GPIO line, since in that case class-D amplifier initialization fails
with "Failed to init class D: -5" message as codec is already held in
reset state after requesting the reset GPIO and hence hardware I/O
fails with -EIO errno.
Thus move class-D amplifier initialization sequence from probe function
to aic3x_set_power() just before the usual regcache sync. Use bypassed
regmap_multi_reg_write_bypassed() function to make sure, class-D init
sequence is performed in proper order as described in the datasheet.

The RPMI System MSI interrupt controller (just like PLIC and APLIC)
needs to probed prior to devices like GED which use interrupts provided
by it. Also, it has dependency on the SBI MPXY mailbox device.
Add HIDs of RPMI System MSI and SBI MPXY mailbox devices to the honor

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Timothy Pearson <tpearson@raptorengineering.com>
[ Upstream commit 8b9f128947dd72e0fcf256088a673abac9b720bf ]
PCI devices prior to PCI 2.3 both use level interrupts and do not support
interrupt masking, leading to a failure when passed through to a KVM guest on
at least the ppc64 platform. This failure manifests as receiving and
acknowledging a single interrupt in the guest, while the device continues to
assert the level interrupt indicating a need for further servicing.
When lazy IRQ masking is used on DisINTx- (non-PCI 2.3) hardware, the following
sequence occurs:
* Level IRQ assertion on device
* IRQ marked disabled in kernel
* Host interrupt handler exits without clearing the interrupt on the device
* Eventfd is delivered to userspace
* Guest processes IRQ and clears device interrupt
* Device de-asserts INTx, then re-asserts INTx while the interrupt is masked
* Newly asserted interrupt acknowledged by kernel VMM without being handled
* Software mask removed by VFIO driver
* Device INTx still asserted, host controller does not see new edge after EOI
The behavior is now platform-dependent. Some platforms (amd64) will continue
to spew IRQs for as long as the INTX line remains asserted, therefore the IRQ
will be handled by the host as soon as the mask is dropped. Others (ppc64) will
only send the one request, and if it is not handled no further interrupts will
be sent. The former behavior theoretically leaves the system vulnerable to
interrupt storm, and the latter will result in the device stalling after
receiving exactly one interrupt in the guest.
Work around this by disabling lazy IRQ masking for DisINTx- INTx devices.

6.12-stable review patch. If anyone has any objections, please let me know.

From: Théo Lebrun <theo.lebrun@bootlin.com>
[ Upstream commit 70a5ce8bc94545ba0fb47b2498bfb12de2132f4d ]
bp->dev->dev_addr is of type `unsigned char *`. Casting it to a u32
pointer and dereferencing implies dealing manually with endianness,
which is error-prone.
Replace by calls to get_unaligned_le32|le16() helpers.
This was found using sparse:
⟩ make C=2 drivers/net/ethernet/cadence/macb_main.o
warning: incorrect type in assignment (different base types)
expected unsigned int [usertype] bottom
got restricted __le32 [usertype]

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arkadiusz Bokowy <arkadiusz.bokowy@gmail.com>
[ Upstream commit 7722d6fb54e428a8f657fccf422095a8d7e2d72c ]
Some Barrot based USB Bluetooth dongles erroneously send one extra
random byte for the HCI_OP_READ_LOCAL_EXT_FEATURES command. The
consequence of that is that the next HCI transfer is misaligned by one
byte causing undefined behavior. In most cases the response event for
the next command fails with random error code.
Since the HCI_OP_READ_LOCAL_EXT_FEATURES command is used during HCI
controller initialization, the initialization fails rendering the USB
dongle not usable.

This patch was tested with the 33fa:0012 device. The info from the

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Pravdin <ipravdin.official@gmail.com>
[ Upstream commit ca94b2b036c22556c3a66f1b80f490882deef7a6 ]
Currently, bcsp_recv() can be called even when the BCSP protocol has not
been registered. This leads to a NULL pointer dereference, as shown in
the following stack trace:
KASAN: null-ptr-deref in range [0x0000000000000108-0x000000000000010f]
RIP: 0010:bcsp_recv+0x13d/0x1740 drivers/bluetooth/hci_bcsp.c:590

To prevent this, ensure that the HCI_UART_REGISTERED flag is set before
processing received data. If the protocol is not registered, return

Drop those frames causing Head-of-Line Blocking due to Scheduling
(HLBS) error to avoid HLBS interrupt flooding and netdev watchdog
timeouts due to blocked packets. Tx queues can be configured to drop
those blocked packets by setting Drop Frames causing Scheduling Error
(DFBS) bit of EST_CONTROL register.
Also, add per queue HLBS drop count.

From: Chi Zhiling <chizhiling@kylinos.cn>
[ Upstream commit 6dfba108387bf4e71411b3da90b2d5cce48ba054 ]
For exFAT filesystems with 4MB read_ahead_size, removing the storage device
when the read operation is in progress, which cause the last read syscall
spent 150s [1]. The main reason is that exFAT generates excessive log
messages [2].
After applying this patch, approximately 300,000 lines of log messages
were suppressed, and the delay of the last read() syscall was reduced
to about 4 seconds.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Namjae Jeon <linkinjeon@kernel.org>
[ Upstream commit 79c1587b6cda74deb0c86fc7ba194b92958c793c ]
syzbot created an exfat image with cluster bits not set for the allocation
bitmap. exfat-fs reads and uses the allocation bitmap without checking
this. The problem is that if the start cluster of the allocation bitmap
is 6, cluster 6 can be allocated when creating a directory with mkdir.
exfat zeros out this cluster in exfat_mkdir, which can delete existing
entries. This can reallocate the allocated entries. In addition,
the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.
This patch adds exfat_test_bitmap_range to validate that clusters used for
the allocation bitmap are correctly marked as in-use.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Qingfang Deng <dqfext@gmail.com>
[ Upstream commit 38b04ed7072e54086102eae2d05d03ffcdb4b695 ]
The TTY layer already serializes line discipline operations with
tty->ldisc_sem, so the extra disc_data_lock and refcnt in 6pack
are unnecessary.
Removing them simplifies the code and also resolves a lockdep warning
reported by syzbot. The warning did not indicate a real deadlock, since
the write-side lock was only taken in process context with hardirqs
disabled.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dragos Tatulea <dtatulea@nvidia.com>
[ Upstream commit a1b501a8c6a87c9265fd03bd004035199e2e8128 ]
page_pool_init() returns E2BIG when the page_pool size goes above 32K
pages. As some drivers are configuring the page_pool size according to
the MTU and ring size, there are cases where this limit is exceeded and
the queue creation fails.
The page_pool size doesn't have to cover a full queue, especially for
larger ring size. So clamp the size instead of returning an error. Do
this in the core to avoid having each driver do the clamping.
The current limit was deemed to high [1] so it was reduced to 16K to avoid
page waste.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mike Marshall <hubcap@omnibond.com>
[ Upstream commit 025e880759c279ec64d0f754fe65bf45961da864 ]
Willy Tarreau <w@1wt.eu> forwarded me a message from
Disclosure <disclosure@aisle.com> with the following
warning:
> The helper `xattr_key()` uses the pointer variable in the loop condition
> rather than dereferencing it. As `key` is incremented, it remains non-NULL
> (until it runs into unmapped memory), so the loop does not terminate on
> valid C strings and will walk memory indefinitely, consuming CPU or hanging
> the thread.
I easily reproduced this with setfattr and getfattr, causing a kernel
oops, hung user processes and corrupted orangefs files. Disclosure
sent along a diff (not a patch) with a suggested fix, which I based
this patch on.
After xattr_key started working right, xfstest generic/069 exposed an
xattr related memory leak that lead to OOM. xattr_key returns
a hashed key. When adding xattrs to the orangefs xattr cache, orangefs
used hash_add, a kernel hashing macro. hash_add also hashes the key using
hash_log which resulted in additions to the xattr cache going to the wrong
hash bucket. generic/069 tortures a single file and orangefs does a
getattr for the xattr "security.capability" every time. Orangefs
negative caches on xattrs which includes a kmalloc. Since adds to the
xattr cache were going to the wrong bucket, every getattr for
"security.capability" resulted in another kmalloc, none of which were
ever freed.
I changed the two uses of hash_add to hlist_add_head instead
and the memory leak ceased and generic/069 quit throwing furniture.

From: Vladimir Riabchun <ferr.lambarginio@gmail.com>
[ Upstream commit 4099b98203d6b33d990586542fa5beee408032a3 ]
A soft lockup was observed when loading amdgpu module.
If a module has a lot of tracable functions, multiple calls
to kallsyms_lookup can spend too much time in RCU critical
section and with disabled preemption, causing kernel panic.
This is the same issue that was fixed in
commit d0b24b4e91fc ("ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY
kernels") and commit 42ea22e754ba ("ftrace: Add cond_resched() to
ftrace_graph_set_hash()").
Fix it the same way by adding cond_resched() in ftrace_module_enable.

From: Fiona Ebner <f.ebner@proxmox.com>
[ Upstream commit 00be6f26a2a7c671f1402d74c4d3c30a5844660a ]
When io_uring is used in the same task as CIFS, there might be
unnecessary reconnects, causing issues in user-space applications
like QEMU with a log like:
> CIFS: VFS: \\10.10.100.81 Error -512 sending data on socket to server
Certain io_uring completions might be added to task_work with
notify_method being TWA_SIGNAL and thus TIF_NOTIFY_SIGNAL is set for
the task.
In __smb_send_rqst(), signals are masked before calling
smb_send_kvec(), but the masking does not apply to TIF_NOTIFY_SIGNAL.
If sk_stream_wait_memory() is reached via sock_sendmsg() while
TIF_NOTIFY_SIGNAL is set, signal_pending(current) will evaluate to
true there, and -EINTR will be propagated all the way from
sk_stream_wait_memory() to sock_sendmsg() in smb_send_kvec().
Afterwards, __smb_send_rqst() will see that not everything was written
and reconnect.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Coiby Xu <coxu@redhat.com>
[ Upstream commit 88b4cbcf6b041ae0f2fc8a34554a5b6a83a2b7cd ]
Currently when both IMA and EVM are in fix mode, the IMA signature will
be reset to IMA hash if a program first stores IMA signature in
security.ima and then writes/removes some other security xattr for the
file.
For example, on Fedora, after booting the kernel with "ima_appraise=fix
evm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,
installing/reinstalling a package will not make good reference IMA
signature generated. Instead IMA hash is generated,
# getfattr -m - -d -e hex /usr/bin/bash
# file: usr/bin/bash
security.ima=0x0404...
This happens because when setting security.selinux, the IMA_DIGSIG flag
that had been set early was cleared. As a result, IMA hash is generated
when the file is closed.
Similarly, IMA signature can be cleared on file close after removing
security xattr like security.evm or setting/removing ACL.
Prevent replacing the IMA file signature with a file hash, by preventing
the IMA_DIGSIG flag from being reset.
Here's a minimal C reproducer which sets security.selinux as the last
step which can also replaced by removing security.evm or setting ACL,
#include <stdio.h>
#include <sys/xattr.h>
#include <fcntl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
int main() {
const char* file_path = "/usr/sbin/test_binary";
const char* hex_string = "030204d33204490066306402304";
int length = strlen(hex_string);
char* ima_attr_value;
int fd;
fd = open(file_path, O_WRONLY|O_CREAT|O_EXCL, 0644);
if (fd == -1) {
perror("Error opening file");
return 1;
}
ima_attr_value = (char*)malloc(length / 2 );
for (int i = 0, j = 0; i < length; i += 2, j++) {
sscanf(hex_string + i, "%2hhx", &ima_attr_value[j]);
}
if (fsetxattr(fd, "security.ima", ima_attr_value, length/2, 0) == -1) {
perror("Error setting extended attribute");
close(fd);
return 1;
}
const char* selinux_value= "system_u:object_r:bin_t:s0";
if (fsetxattr(fd, "security.selinux", selinux_value, strlen(selinux_value), 0) == -1) {
perror("Error setting extended attribute");
close(fd);
return 1;
}
close(fd);

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Pecio <michal.pecio@gmail.com>
[ Upstream commit 8607edcd1748503f4f58e66ca0216170f260c79b ]
A recent change to hide USB3 root hubs of USB2-only controllers broke
registration of USB2 root hubs - allow_single_roothub is set too late,
and by this time xhci_run() has already deferred root hub registration
until after the shared HCD is added, which will never happen.
This makes such controllers unusable, but testers didn't notice since
they were only bothered by warnings about empty USB3 root hubs. The bug
causes problems to other people who actually use such HCs and I was
able to confirm it on an ordinary HC by patching to ignore USB3 ports.
Setting allow_single_roothub during early setup fixes things.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
[ Upstream commit 31b636d2c41613e3bd36256a4bd53e9dacfa2677 ]
When this was first reported [1], the possibility of having sufficient
number of dynamic misc devices was theoretical, in the case of dlm driver.
In practice, its userspace never created more than one device.
What we know from commit ab760791c0cf ("char: misc: Increase the maximum
number of dynamic misc devices to 1048448"), is that the miscdevice
interface has been used for allocating more than the single-shot devices it
was designed for. And it is not only coresight_tmc, but many other drivers
are able to create multiple devices.
On systems like the ones described in the above commit, it is certain that
the dynamic allocation will allocate certain reserved minor numbers,
leading to failures when a later driver tries to claim its reserved number.
Instead of excluding the historically statically allocated range from
dynamic allocation, restrict the latter to minors above 255. That also
removes the need for DYNAMIC_MINORS and the convolution in allocating minor
numbers, simplifying the code.
Since commit ab760791c0cf ("char: misc: Increase the maximum number of
dynamic misc devices to 1048448") has been applied, such range is already
possible. And given such devices already need to be dynamically created,
there should be no systems where this might become a problem.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <Mario.Limonciello@amd.com>
[ Upstream commit db291ed1732e02e79dca431838713bbf602bda1c ]
[Why]
DP validation may fail with multiple displays and higher color depths.
The sink may support others though.
[How]
When DP bandwidth validation fails, progressively fallback through:
- YUV422 8bpc (bandwidth efficient)
- YUV422 6bpc (reduced color depth)
- YUV420 (last resort)
This resolves cases where displays would show no image due to insufficient
DP link bandwidth for the requested RGB mode.

From: Jacob Moroni <jmoroni@google.com>
[ Upstream commit 8d158f47f1f33d8747e80c3afbea5aa337e59d41 ]
In some cases, it is possible for pble_rsrc->next_fpm_addr to be
larger than u32, so remove the u32 cast to avoid unintentional
truncation.
This fixes the following error that can be observed when registering
massive memory regions:
[ 447.227494] (NULL ib_device): cqp opcode = 0x1f maj_err_code = 0xffff min_err_code = 0x800c
[ 447.227505] (NULL ib_device): [Update PE SDs Cmd Error][op_code=21] status=-5 waiting=1 completion_err=1 maj=0xffff min=0x800c

------------------
From: Jacob Moroni <jmoroni@google.com>
[ Upstream commit 5575b7646b94c0afb0f4c0d86e00e13cf3397a62 ]
The driver maintains a CQ table that is used to ensure that a CQ is
still valid when processing CQ related AEs. When a CQ is destroyed,
the table entry is cleared, using irdma_cq.cq_num as the index. This
field was never being set, so it was just always clearing out entry
0.
Additionally, the cq_num field size was increased to accommodate HW
supporting more than 64K CQs.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chengchang Tang <tangchengchang@huawei.com>
[ Upstream commit c4b67b514af8c2d73c64b36e0cd99e9b26b9ac82 ]
Currently driver enforces affinity between QP cache and send CQ
cache, which helps improve the performance of sending, but doesn't
set affinity with recv CQ cache, resulting in suboptimal performance
of receiving.
Use one CQ bank per context to ensure the affinity among QP, send CQ
and recv CQ. For kernel ULP, CQ bank is fixed to 0.

[ Upstream commit f5a7cbea5411668d429eb4ffe96c4063fe8dac9e ]
The actual sge number may exceed the value specified in init_attr->cap
when HW needs extra sge to enable inline feature. Since these extra
sges are not expected by ULP, return the user-specified value to ULP
instead of the expanded sge number.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junxian Huang <huangjunxian6@hisilicon.com>
[ Upstream commit fe9622011f955e35ba84d3af7b2f2fed31cf8ca1 ]
When QP wraps around, WQE data from the previous use at the same
position still remains as driver does not clear it. The WQE field
layout differs across different opcodes, causing that the fields
that are not explicitly assigned for the current opcode retain
stale values, and are issued to HW by mistake. Such fields are as
follows:
* MSG_START_SGE_IDX field in ATOMIC WQE
* BLOCK_SIZE and ZBVA fields in FRMR WQE
* DirectWQE fields when DirectWQE not used
For ATOMIC WQE, always set the latest sge index in MSG_START_SGE_IDX
as required by HW.
For FRMR WQE and DirectWQE, clear only those unassigned fields
instead of the entire WQE to avoid performance penalty.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shardul Bankar <shardulsb08@gmail.com>
[ Upstream commit f260c6aff0b8af236084012d14f9f1bf792ea883 ]
When btrfs_add_qgroup_relation() is called with invalid qgroup levels
(src >= dst), the function returns -EINVAL directly without freeing the
preallocated qgroup_list structure passed by the caller. This causes a
memory leak because the caller unconditionally sets the pointer to NULL
after the call, preventing any cleanup.
The issue occurs because the level validation check happens before the
mutex is acquired and before any error handling path that would free
the prealloc pointer. On this early return, the cleanup code at the
'out' label (which includes kfree(prealloc)) is never reached.
In btrfs_ioctl_qgroup_assign(), the code pattern is:
prealloc = kzalloc(sizeof(*prealloc), GFP_KERNEL);
ret = btrfs_add_qgroup_relation(trans, sa->src, sa->dst, prealloc);
prealloc = NULL; // Always set to NULL regardless of return value
...
kfree(prealloc); // This becomes kfree(NULL), does nothing
When the level check fails, 'prealloc' is never freed by either the
callee or the caller, resulting in a 64-byte memory leak per failed
operation. This can be triggered repeatedly by an unprivileged user
with access to a writable btrfs mount, potentially exhausting kernel
memory.
Fix this by freeing prealloc before the early return, ensuring prealloc
is always freed on all error paths.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: austinchang <austinchang@synology.com>
[ Upstream commit 3b1a4a59a2086badab391687a6a0b86e03048393 ]
In btrfs_fallocate(), when the allocated range overlaps with a prealloc
extent and the extent starts after i_size, the range doesn't get marked
dirty in file_extent_tree. This results in persisting an incorrect
disk_i_size for the inode when not using the no-holes feature.
This is reproducible since commit 41a2ee75aab0 ("btrfs: introduce
per-inode file extent tree"), then became hidden since commit 3d7db6e8bd22
("btrfs: don't allocate file extent tree for non regular files") and then
visible again after commit 8679d2687c35 ("btrfs: initialize
inode::file_extent_tree after i_mode has been set"), which fixes the
previous commit.
The following reproducer triggers the problem:
$ cat test.sh
MNT=/mnt/test
DEV=/dev/vdb
mkdir -p $MNT
mkfs.btrfs -f -O ^no-holes $DEV
mount $DEV $MNT
touch $MNT/file1
fallocate -n -o 1M -l 2M $MNT/file1
umount $MNT
mount $DEV $MNT
len=$((1 * 1024 * 1024))
fallocate -o 1M -l $len $MNT/file1
du --bytes $MNT/file1
umount $MNT
mount $DEV $MNT
du --bytes $MNT/file1
umount $MNT
Running the reproducer gives the following result:
$ ./test.sh
(...)
2097152 /mnt/test/file1
1048576 /mnt/test/file1
The difference is exactly 1048576 as we assigned.
Fix by adding a call to btrfs_inode_set_file_extent_range() in
btrfs_fallocate_update_isize().

------------------
From: Marko Mäkelä <marko.makela@iki.fi>
[ Upstream commit 2f7b168323c22faafb1fbf94ef93b7ce5efc15c6 ]
Rework nss_port5 to use the new multiple configuration implementation
and correctly fix the clocks for this port under some corner case.
In OpenWrt, this patch avoids intermittent dmesg errors of the form
nss_port5_rx_clk_src: rcg didn't update its configuration.
This is a mechanical, straightforward port of
commit e88f03230dc07aa3293b6aeb078bd27370bb2594
("clk: qcom: gcc-ipq8074: rework nss_port5/6 clock to multiple conf")
to gcc-ipq6018, with two conflicts resolved: different frequency of the
P_XO clock source, and only 5 Ethernet ports.
This was originally developed by JiaY-shi <shi05275@163.com>.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yikang Yue <yikangy2@illinois.edu>
[ Upstream commit 32058c38d3b79a28963a59ac0353644dc24775cd ]
The function call new_inode() is a primitive for allocating an inode in memory,
rather than planning disk space for it. Therefore, -ENOMEM should be returned
as the error code rather than -ENOSPC.
To be specific, new_inode()'s call path looks like this:
new_inode
new_inode_pseudo
alloc_inode
ops->alloc_inode (hpfs_alloc_inode)
alloc_inode_sb
kmem_cache_alloc_lru
Therefore, the failure of new_inode() indicates a memory presure issue (-ENOMEM),
not a lack of disk space. However, the current implementation of
hpfs_mkdir/create/mknod/symlink incorrectly returns -ENOSPC when new_inode() fails.
This patch fix this by set err to -ENOMEM before the goto statement.
BTW, we also noticed that other nested calls within these four functions,
like hpfs_alloc_f/dnode and hpfs_add_dirent, might also fail due to memory presure.
But similarly, only -ENOSPC is returned. Addressing these will involve code
modifications in other functions, and we plan to submit dedicated patches for these
issues in the future. For this patch, we focus on new_inode().

From: Chen-Yu Tsai <wens@csie.org>
[ Upstream commit 7aa8781f379c32c31bd78f1408a31765b2297c43 ]
The A523's RTC block is backward compatible with the R329's, but it also
has a calibration function for its internal oscillator, which would
allow it to provide a clock rate closer to the desired 32.768 KHz. This
is useful on the Radxa Cubie A5E, which does not have an external 32.768
KHz crystal.
Add new compatible-specific data for it.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josua Mayer <josua@solid-run.com>
[ Upstream commit a6f1a4f05970664004a9370459c6799c1b2f2dcf ]
PCF2127 can generate interrupt every full second or minute configured
from control and status register 1, bits MI (1) and SI (0).
On interrupt control register 2 bit MSF (7) is set and must be cleared
to continue normal operation.
While the driver never enables this interrupt on its own, users or
firmware may do so - e.g. as an easy way to test the interrupt.
Add preprocessor definition for MSF bit and include it in the irq
bitmask to ensure minute and second interrupts are cleared when fired.
This fixes an issue where the rtc enters a test mode and becomes
unresponsive after a second interrupt has fired and is not cleared in
time. In this state register writes to control registers have no
effect and the interrupt line is kept asserted [1]:
[1] userspace commands to put rtc into unresponsive state:
$ i2cget -f -y 2 0x51 0x00
0x04
$ i2cset -f -y 2 0x51 0x00 0x05 # set bit 0 SI
$ i2cget -f -y 2 0x51 0x00
0x84 # bit 8 EXT_TEST set
$ i2cset -f -y 2 0x51 0x00 0x05 # try overwrite control register
$ i2cget -f -y 2 0x51 0x00
0x84 # no change

A potential divider for the master clock is div/3. The register
configuration for div/3 is MASTER_PRES_MAX. The current bit shifting
method does not work for this case. Checking for MASTER_PRES_MAX will
ensure the correct decimal value is stored in the system.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Ferre <nicolas.ferre@microchip.com>
[ Upstream commit af98caeaa7b6ad11eb7b7c8bfaddc769df2889f3 ]
This register is important for sequencing the commands to PLLs, so
actually write the update bits with regmap_write_bits() instead of
relying on a read/modify/write regmap command that could skip the actual
hardware write if the value is identical to the one read.
It's changed when modification is needed to the PLL, when
read-only operation is done, we could keep the call to
regmap_update_bits().
Add a comment to the sam9x60_div_pll_set_div() function that uses this
PLL_UPDT register so that it's used consistently, according to the
product's datasheet.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oleg Nesterov <oleg@redhat.com>
[ Upstream commit e8fe3f07a357c39d429e02ca34f740692d88967a ]
p9_read_work() doesn't set Rworksched and doesn't do schedule_work(m->rq)
if list_empty(&m->req_list).
However, if the pipe is full, we need to read more data and this used to
work prior to commit aaec5a95d59615 ("pipe_read: don't wake up the writer
if the pipe is still full").
p9_read_work() does p9_fd_read() -> ... -> anon_pipe_read() which (before
the commit above) triggered the unnecessary wakeup. This wakeup calls
p9_pollwake() which kicks p9_poll_workfn() -> p9_poll_mux(), p9_poll_mux()
will notice EPOLLIN and schedule_work(&m->rq).
This no longer happens after the optimization above, change p9_fd_request()
to use p9_poll_mux() instead of only checking for EPOLLOUT.

As described in AM335x Errata Advisory 1.0.42, WKUP_DEBUGSS_CLKCTRL
can't be disabled - the clock module will just be stuck in transitioning
state forever, resulting in the following warning message after the wait
loop times out:

Just add the clock to enable_init_clks, so no attempt is made to disable
it.

[ Upstream commit 7c2e86f7b5af93d0e78c16e4359318fe7797671d ]
The output clock register offset used in clk_wzrd_register_output_clocks
was incorrectly referencing 0x3C instead of 0x38, which caused
misconfiguration of output dividers on Versal platforms.
Correcting the off-by-one error ensures proper configuration of output
clocks.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jerome Brunet <jbrunet@baylibre.com>
[ Upstream commit 5ad865862a0fd349163243e1834ed98ba9b81905 ]
The NTB epf host driver assumes the BAR number associated with a memory
window is just incremented from the BAR number associated with MW1. This
seems to have been enough so far but this is not really how the endpoint
side work and the two could easily become mis-aligned.
ntb_epf_mw_to_bar() even assumes that the BAR number is the memory window
index + 2, which means the function only returns a proper result if BAR_2
is associated with MW1.
Instead, fully describe and allow arbitrary NTB BAR mapping.

Properly append with snprintf(buf + count, …).

[ Upstream commit ba6018929165fc914c665f071f8e8cdbac844a49 ]
During initialization, the EDVD_COREx_VOLT_FREQ registers for some cores
are still at reset values and not reflecting the actual frequency. This
causes get calls to fail. Set all cores to their respective max
frequency during probe to initialize the registers to working values.

When a UTP error occurs in isolation, UFS is not currently recoverable.
This is because the UTP error is not considered fatal in the error
handling code, leading to either an I/O timeout or an OCS error.
Add the UTP error flag to INT_FATAL_ERRORS so the controller will be
reset in this situation.

------------------
From: Sakari Ailus <sakari.ailus@linux.intel.com>
[ Upstream commit d9f866b2bb3eec38b3734f1fed325ec7c55ccdfa ]
fwnode_graph_get_next_subnode() may return fwnode backed by ACPI
device nodes and there has been no check these devices are present
in the system, unlike there has been on fwnode OF backend.
In order to provide consistent behaviour towards callers,
add a check for device presence by introducing
a new function acpi_get_next_present_subnode(), used as the
get_next_child_node() fwnode operation that also checks device
node presence.

The atomic instructions sc.q, llacq.{w/d}, screl.{w/d} were newly added
in the LoongArch Reference Manual v1.10, it is necessary to handle them
in insns_not_supported() to avoid putting a breakpoint in the middle of
a ll/sc atomic sequence, otherwise it will loop forever for kprobes and
uprobes.

[ Upstream commit f38ce0209ab4553906b44bd1159e35c740a84161 ]
small_const_nbits is defined in asm-generic/bitsperlong.h which
bitmap.h uses but doesn't include causing build failures in some build
systems. Add the missing #include.
Note the bitmap.h in tools has diverged from that of the kernel, so no
changes are made there.

Instead of preserving mode, timestamp, and owner, for the object files
during installation, just preserve the mode and timestamp.
When installing as root, the installed files should be owned by root.
When installing as user, --preserve=ownership doesn't work anyway. This
makes --preserve=ownership rather pointless.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Albin Babu Varghese <albinbabuvarghese20@gmail.com>
[ Upstream commit 3637d34b35b287ab830e66048841ace404382b67 ]
Add bounds checking to prevent writes past framebuffer boundaries when
rendering text near screen edges. Return early if the Y position is off-screen
and clip image height to screen boundary. Break from the rendering loop if the
X position is off-screen. When clipping image width to fit the screen, update
the character count to match the clipped width to prevent buffer size
mismatches.
Without the character count update, bit_putcs_aligned and bit_putcs_unaligned
receive mismatched parameters where the buffer is allocated for the clipped
width but cnt reflects the original larger count, causing out-of-bounds writes.

------------------
From: Geert Uytterhoeven <geert@linux-m68k.org>
[ Upstream commit 66128f4287b04aef4d4db9bf5035985ab51487d5 ]
On m68k, check_sizetypes in headers_check reports:
./usr/include/asm/bootinfo-amiga.h:17: found __[us]{8,16,32,64} type without #include <linux/types.h>
This header file does not use any of the Linux-specific integer types,
but merely refers to them from comments, so this is a false positive.
As of commit c3a9d74ee413bdb3 ("kbuild: uapi: upgrade check_sizetypes()
warning to error"), this check was promoted to an error, breaking m68k
all{mod,yes}config builds.
Fix this by stripping simple comments before looking for Linux-specific
integer types.

From: Valerio Setti <vsetti@baylibre.com>
[ Upstream commit 4c4ed5e073a923fb3323022e1131cb51ad8df7a0 ]
According to I2S specs audio data is sampled on the rising edge of the
clock and it can change on the falling one. When operating in normal mode
this SoC behaves the opposite so a clock polarity inversion is required
in this case.
This was tested on an OdroidC2 (Amlogic S905 SoC) board.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Viacheslav Dubeyko <Slava.Dubeyko@ibm.com>
[ Upstream commit 5824ccba9a39a3ad914fc9b2972a2c1119abaac9 ]
The Coverity Scan service has detected potential
race condition in ceph_ioctl_lazyio() [1].
The CID 1591046 contains explanation: "Check of thread-shared
field evades lock acquisition (LOCK_EVASION). Thread1 sets
fmode to a new value. Now the two threads have an inconsistent
view of fmode and updates to fields correlated with fmode
may be lost. The data guarded by this critical section may
be read while in an inconsistent state or modified by multiple
racing threads. In ceph_ioctl_lazyio: Checking the value of
a thread-shared field outside of a locked region to determine
if a locked operation involving that thread shared field
has completed. (CWE-543)".
The patch places fi->fmode field access under ci->i_ceph_lock
protection. Also, it introduces the is_file_already_lazy
variable that is set under the lock and it is checked later
out of scope of critical section.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Viacheslav Dubeyko <Slava.Dubeyko@ibm.com>
[ Upstream commit 53db6f25ee47cb1265141d31562604e56146919a ]
The wake_up_bit() is called in ceph_async_unlink_cb(),
wake_async_create_waiters(), and ceph_finish_async_create().
It makes sense to switch on clear_bit() function, because
it makes the code much cleaner and easier to understand.
More important rework is the adding of smp_mb__after_atomic()
memory barrier after the bit modification and before
wake_up_bit() call. It can prevent potential race condition
of accessing the modified bit in other threads. Luckily,
clear_and_wake_up_bit() already implements the required
functionality pattern:
static inline void clear_and_wake_up_bit(int bit, unsigned long *word)
{
clear_bit_unlock(bit, word);
/* See wake_up_bit() for which memory barrier you need to use. */
smp_mb__after_atomic();
wake_up_bit(word, bit);
}

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kotresh HR <khiremat@redhat.com>
[ Upstream commit 22c73d52a6d05c5a2053385c0d6cd9984732799d ]
The mds auth caps check should also validate the
fsname along with the associated caps. Not doing
so would result in applying the mds auth caps of
one fs on to the other fs in a multifs ceph cluster.
The bug causes multiple issues w.r.t user
authentication, following is one such example.
Steps to Reproduce (on vstart cluster):
1. Create two file systems in a cluster, say 'fsname1' and 'fsname2'
2. Authorize read only permission to the user 'client.usr' on fs 'fsname1'
$ceph fs authorize fsname1 client.usr / r
3. Authorize read and write permission to the same user 'client.usr' on fs 'fsname2'
$ceph fs authorize fsname2 client.usr / rw
4. Update the keyring
$ceph auth get client.usr >> ./keyring
With above permssions for the user 'client.usr', following is the
expectation.
a. The 'client.usr' should be able to only read the contents
and not allowed to create or delete files on file system 'fsname1'.
b. The 'client.usr' should be able to read/write on file system 'fsname2'.
But, with this bug, the 'client.usr' is allowed to read/write on file
system 'fsname1'. See below.
5. Mount the file system 'fsname1' with the user 'client.usr'
$sudo bin/mount.ceph usr@.fsname1=/ /kmnt_fsname1_usr/
6. Try creating a file on file system 'fsname1' with user 'client.usr'. This
should fail but passes with this bug.
$touch /kmnt_fsname1_usr/file1
7. Mount the file system 'fsname1' with the user 'client.admin' and create a
file.
$sudo bin/mount.ceph admin@.fsname1=/ /kmnt_fsname1_admin
$echo "data" > /kmnt_fsname1_admin/admin_file1
8. Try removing an existing file on file system 'fsname1' with the user
'client.usr'. This shoudn't succeed but succeeds with the bug.
$rm -f /kmnt_fsname1_usr/admin_file1
For more information, please take a look at the corresponding mds/fuse patch
and tests added by looking into the tracker mentioned below.
v2: Fix a possible null dereference in doutc
v3: Don't store fsname from mdsmap, validate against
ceph_mount_options's fsname and use it
v4: Code refactor, better warning message and
fix possible compiler warning

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
[ Upstream commit 91309a70829d94c735c8bb1cc383e78c96127a16 ]
This was a suggestion by David Laight, and while I was slightly worried
that some micro-architecture would predict cmov like a conditional
branch, there is little reason to actually believe any core would be
that broken.
Intel documents that their existing cores treat CMOVcc as a data
dependency that will constrain speculation in their "Speculative
Execution Side Channel Mitigations" whitepaper:
"Other instructions such as CMOVcc, AND, ADC, SBB and SETcc can also
be used to prevent bounds check bypass by constraining speculative
execution on current family 6 processors (Intel® Core™, Intel® Atom™,
Intel® Xeon® and Intel® Xeon Phi™ processors)"
and while that leaves the future uarch issues open, that's certainly
true of our traditional SBB usage too.
Any core that predicts CMOV will be unusable for various crypto
algorithms that need data-independent timing stability, so let's just
treat CMOV as the safe choice that simplifies the address masking by
avoiding an extra instruction and doesn't need a temporary register.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
[ Upstream commit 284922f4c563aa3a8558a00f2a05722133237fe8 ]
The runtime-const infrastructure was never designed to handle the
modular case, because the constant fixup is only done at boot time for
core kernel code.
But by the time I used it for the x86-64 user space limit handling in
commit 86e6b1547b3d ("x86: fix user address masking non-canonical
speculation issue"), I had completely repressed that fact.
And it all happens to work because the only code that currently actually
gets inlined by modules is for the access_ok() limit check, where the
default constant value works even when not fixed up. Because at least I
had intentionally made it be something that is in the non-canonical
address space region.
But it's technically very wrong, and it does mean that at least in
theory, the use of 'access_ok()' + '__get_user()' can trigger the same
speculation issue with non-canonical addresses that the original commit
was all about.
The pattern is unusual enough that this probably doesn't matter in
practice, but very wrong is still very wrong. Also, let's fix it before
the nice optimized scoped user accessor helpers that Thomas Gleixner is
working on cause this pseudo-constant to then be more widely used.
This all came up due to an unrelated discussion with Mateusz Guzik about
using the runtime const infrastructure for names_cachep accesses too.
There the modular case was much more obviously broken, and Mateusz noted
it in his 'v2' of the patch series.
That then made me notice how broken 'access_ok()' had been in modules
all along. Mea culpa, mea maxima culpa.
Fix it by simply not using the runtime-const code in modules, and just
using the USER_PTR_MAX variable value instead. This is not
performance-critical like the core user accessor functions (get_user()
and friends) are.
Also make sure this doesn't get forgotten the next time somebody wants
to do runtime constant optimizations by having the x86 runtime-const.h
header file error out if included by modules.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kailang Yang <kailang@realtek.com>
[ Upstream commit f4b3cef55f5f96fdb4e7f9ca90b7d6213689faeb ]
There was a similar bug in the past (Bug 217440), which was fixed for
this laptop.
The same issue is occurring again as of kernel v.6.12.2. The symptoms
are very similar - initially audio works but after a warm reboot, the
audio completely disappears until the computer is powered off (there
is no audio output at all).
The issue is also related by caused by a different change now. By
bisecting different kernel versions, I found that reverting
cc3d0b5dd989 in patch_realtek.c[*] restores the sound and it works
fine after the reboot.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Qu Wenruo <wqu@suse.com>
commit 2618849f31e7cf51fadd4a5242458501a6d5b315 upstream.
[BUG]
During development of a minor feature (make sure all btrfs_bio::end_io()
is called in task context), I noticed a crash in generic/388, where
metadata writes triggered new works after btrfs_stop_all_workers().
It turns out that it can even happen without any code modification, just
using RAID5 for metadata and the same workload from generic/388 is going
to trigger the use-after-free.
[CAUSE]
If btrfs hits an error, the fs is marked as error, no new
transaction is allowed thus metadata is in a frozen state.
But there are some metadata modifications before that error, and they are
still in the btree inode page cache.
Since there will be no real transaction commit, all those dirty folios
are just kept as is in the page cache, and they can not be invalidated
by invalidate_inode_pages2() call inside close_ctree(), because they are
dirty.
And finally after btrfs_stop_all_workers(), we call iput() on btree
inode, which triggers writeback of those dirty metadata.
And if the fs is using RAID56 metadata, this will trigger RMW and queue
new works into rmw_workers, which is already stopped, causing warning
from queue_work() and use-after-free.
[FIX]
Add a special handling for write_one_eb(), that if the fs is already in
an error state, immediately mark the bbio as failure, instead of really
submitting them.
Then during close_ctree(), iput() will just discard all those dirty
tree blocks without really writing them back, thus no more new jobs for
already stopped-and-freed workqueues.
The extra discard in write_one_eb() also acts as an extra safenet.
E.g. the transaction abort is triggered by some extent/free space
tree corruptions, and since extent/free space tree is already corrupted
some tree blocks may be allocated where they shouldn't be (overwriting
existing tree blocks). In that case writing them back will further
corrupting the fs.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit 758dbc756aad429da11c569c0d067f7fd032bcf7 upstream.
Some devices, like the Grandstream GUV3100 webcam, have an invalid UVC
descriptor where multiple entities share the same ID, this is invalid
and makes it impossible to make a proper entity tree without heuristics.
We have recently introduced a change in the way that we handle invalid
entities that has caused a regression on broken devices.
Implement a new heuristic to handle these devices properly.

commit 27afd6e066cfd80ddbe22a4a11b99174ac89cced upstream.
vb2_ioctl_remove_bufs() call manipulates queue internal buffer list,
potentially overwriting some pointers used by the legacy fileio access
mode. Forbid that ioctl when fileio is active to protect internal queue
state between subsequent read/write calls.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ariel D'Alessandro <ariel.dalessandro@collabora.com>
commit 9882a40640036d5bbc590426a78981526d4f2345 upstream.
Commit c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek DRM
driver") added AFBC support to Mediatek DRM and enabled the
32x8/split/sparse modifier.
However, this is currently broken on Mediatek MT8188 (Genio 700 EVK
platform); tested using upstream Kernel and Mesa (v25.2.1), AFBC is used by
default since Mesa v25.0.
Kernel trace reports vblank timeouts constantly, and the render is garbled:

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Baochen Qiang <baochen.qiang@oss.qualcomm.com>
commit 2469bb6a6af944755a7d7daf66be90f3b8decbf9 upstream.
This reverts commit 51a73f1b2e56b0324b4a3bb8cebc4221b5be4c7a.
Although this commit benefits QCA6174, it breaks QCA988x and
QCA9984 [1][2]. Since it is not likely to root cause/fix this
issue in a short time, revert it to get those chips back.
Compile tested only.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt <rostedt@goodmis.org>
commit aa997d2d2a0b2e76f4df0f1f12829f02acb4fb6b upstream.
The function ring_buffer_map_get_reader() is a bit more strict than the
other get reader functions, and except for certain situations the
rb_get_reader_page() should not return NULL. If it does, it triggers a
warning.
This warning was triggering but after looking at why, it was because
another acceptable situation was happening and it wasn't checked for.
If the reader catches up to the writer and there's still data to be read
on the reader page, then the rb_get_reader_page() will return NULL as
there's no new page to get.
In this situation, the reader page should not be updated and no warning
should trigger.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiawen Wu <jiawenwu@trustnetic.com>
commit a04ea57aae375bdda1cb57034d8bcbb351e1f973 upstream.
The device bus LAN ID was obtained from PCI_FUNC(), but when a PF
port is passthrough to a virtual machine, the function number may not
match the actual port index on the device. This could cause the driver
to perform operations such as LAN reset on the wrong port.
Fix this by reading the LAN ID from port status register.

From: Chunyan Zhang <zhangchunyan@iscas.ac.cn>
[ Upstream commit 060ea84a484e852b52b938f234bf9b5503a6c910 ]
Unwinding the stack of a task other than current, KASAN would report
"BUG: KASAN: out-of-bounds in walk_stackframe+0x41c/0x460"
There is a same issue on x86 and has been resolved by the commit
84936118bdf3 ("x86/unwind: Disable KASAN checks for non-current tasks")
The solution could be applied to RISC-V too.
This patch also can solve the issue:

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josephine Pfeiffer <hi@josie.lol>
[ Upstream commit a74f038fa50e0d33b740f44f862fe856f16de6a8 ]
The pt_dump_seq_puts() macro incorrectly uses seq_printf() instead of
seq_puts(). This is both a performance issue and conceptually wrong,
as the macro name suggests plain string output (puts) but the
implementation uses formatted output (printf).
The macro is used in ptdump.c:301 to output a newline character. Using
seq_printf() adds unnecessary overhead for format string parsing when
outputting this constant string.
This bug was introduced in commit 59c4da8640cc ("riscv: Add support to
dump the kernel page tables") in 2020, which copied the implementation
pattern from other architectures that had the same bug.

[ Upstream commit 5c5f1f64681cc889d9b13e4a61285e9e029d6ab5 ]
In hci_cmd_complete_evt(), if the command complete event has an unknown
opcode, we assume the first byte of the remaining skb->data contains the
return status. However, parameter data has previously been pulled in
hci_event_func(), which may leave the skb empty. If so, using skb->data[0]
for the return status uses un-init memory.
The fix is to check skb->len before using skb->data.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit 3d18a84eddde169d6dbf3c72cc5358b988c347d0 ]
The internal switch on BCM63XX SoCs will unconditionally add 802.1Q VLAN
tags on egress to CPU when 802.1Q mode is enabled. We do this
unconditionally since commit ed409f3bbaa5 ("net: dsa: b53: Configure
VLANs while not filtering").
This is fine for VLAN aware bridges, but for standalone ports and vlan
unaware bridges this means all packets are tagged with the default VID,
which is 0.
While the kernel will treat that like untagged, this can break userspace
applications processing raw packets, expecting untagged traffic, like
STP daemons.
This also breaks several bridge tests, where the tcpdump output then
does not match the expected output anymore.
Since 0 isn't a valid VID, just strip out the VLAN tag if we encounter
it, unless the priority field is set, since that would be a valid tag
again.

From: Anubhav Singh <anubhavsinggh@google.com>
[ Upstream commit 02d064de05b1fcca769391fa82d205bed8bb9bf0 ]
Due to the gro_sender sending data packets and FIN packets
in very quick succession, these are received almost simultaneously
by the gro_receiver. FIN packets are sometimes processed before the
data packets leading to intermittent (~1/100) test failures.
This change adds a delay of 100ms before sending FIN packets
in gro:tcp test to avoid the out-of-order delivery. The same
mitigation already exists for the gro:ip test.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anubhav Singh <anubhavsinggh@google.com>
[ Upstream commit f8e8486702abb05b8c734093aab1606af0eac068 ]
The GRO self-test, gro.c, currently constructs IPv6 packets containing a
Hop-by-Hop Options header (IPPROTO_HOPOPTS) to ensure the GRO path
correctly handles IPv6 extension headers.
However, network elements may be configured to drop packets with the
Hop-by-Hop Options header (HBH). This causes the self-test to fail
in environments where such network elements are present.
To improve the robustness and reliability of this test in diverse
network environments, switch from using IPPROTO_HOPOPTS to
IPPROTO_DSTOPTS (Destination Options).
The Destination Options header is less likely to be dropped by
intermediate routers and still serves the core purpose of the test:
validating GRO's handling of an IPv6 extension header. This change
ensures the test can execute successfully without being incorrectly
failed by network policies outside the kernel's control.

From: Hangbin Liu <liuhangbin@gmail.com>
[ Upstream commit c211f5d7cbd5cb34489d526648bb9c8ecc907dee ]
After registering a VLAN device and setting its feature flags, we need to
synchronize the VLAN features with the lower device. For example, the VLAN
device does not have the NETIF_F_LRO flag, it should be synchronized with
the lower device based on the NETIF_F_UPPER_DISABLES definition.
As the dev->vlan_features has changed, we need to call
netdev_update_features(). The caller must run after netdev_upper_dev_link()
links the lower devices, so this patch adds the netdev_update_features()
call in register_vlan_dev().

[ Upstream commit e5d527be7e6984882306b49c067f1fec18920735 ]
Looking up a GPIO controller by label that is the name of the software
node is wonky at best - the GPIO controller driver is free to set
a different label than the name of its firmware node. We're already being
passed a firmware node handle attached to the GPIO device to
swnode_get_gpio_device() so use it instead for a more precise lookup.

From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit b6a8a5477fe9bd6be2b594a88f82f8bba41e6d54 ]
There is no guarantee that the port state override registers have their
default values, as not all switches support being reset via register or
have a reset GPIO.
So when forcing port config, we need to make sure to clear all fields,
which we currently do not do for the speed and flow control
configuration. This can cause flow control stay enabled, or in the case
of speed becoming an illegal value, e.g. configured for 1G (0x2), then
setting 100M (0x1), results in 0x3 which is invalid.
For PORT_OVERRIDE_SPEED_2000M we need to make sure to only clear it on
supported chips, as the bit can have different meanings on other chips,
e.g. for BCM5389 this controls scanning PHYs for link/speed
configuration.

From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit 3e4ebdc1606adf77744cf8ed7a433d279fdc57ba ]
BCM63XX's switch does not support MDIO scanning of external phys, so its
MACs needs to be manually configured for autonegotiated link speeds.
So b53_force_port_config() and b53_force_link() accordingly also when
mode is MLO_AN_PHY for those ports.
Fixes lower speeds than 1000/full on rgmii ports 4 - 7.
This aligns the behaviour with the old bcm63xx_enetsw driver for those
ports.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit c264294624e956a967a9e2e5fa41e3273340b089 ]
In the New Control register bit 1 is either reserved, or has a different
function:
Out of Range Error Discard
When enabled, the ingress port discards any frames
if the Length field is between 1500 and 1536
(excluding 1500 and 1536) and with good CRC.
The actual bit for enabling IP multicast is bit 0, which was only
explicitly enabled for BCM5325 so far.
For older switch chips, this bit defaults to 0, so we want to enable it
as well, while newer switch chips default to 1, and their documentation
says "It is illegal to set this bit to zero."
So drop the wrong B53_IPMC_FWD_EN define, enable the IP multicast bit
also for other switch chips. While at it, rename it to (B53_)IP_MC as
that is how it is called in Broadcom code.

From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit 0be04b5fa62a82a9929ca261f6c9f64a3d0a28da ]
The switch clears the ARL_SRCH_STDN bit when the search is done, i.e. it
finished traversing the ARL table.
This means that there will be no valid result, so we should not attempt
to read and process any further entries.
We only ever check the validity of the entries for 4 ARL bin chips, and
only after having passed the first entry to the b53_fdb_copy().
This means that we always pass an invalid entry at the end to the
b53_fdb_copy(). b53_fdb_copy() does check the validity though before
passing on the entry, so it never gets passed on.
On < 4 ARL bin chips, we will even continue reading invalid entries
until we reach the result limit.

For the following path not holding the sock lock,
sctp_diag_dump() -> sctp_for_each_endpoint() -> sctp_ep_dump()
make sure not to exceed bounds in case the address list has grown
between buffer allocation (time-of-check) and write (time-of-use).

From: Mohammad Heib <mheib@redhat.com>
[ Upstream commit d261f5b09c28850dc63ca1d3018596f829f402d5 ]
The TX path currently writes descriptors and then immediately writes to
the MMIO doorbell register to notify the NIC. On weakly ordered
architectures, descriptor writes may still be pending in CPU or DMA
write buffers when the doorbell is issued, leading to the device
fetching stale or incomplete descriptors.
Add a dma_wmb() in ionic_txq_post() to ensure all descriptor writes are
visible to the device before the doorbell MMIO write.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mohammad Heib <mheib@redhat.com>
[ Upstream commit de0337d641bfa5b6d6b489e479792f1039274e84 ]
The TSO path called ionic_tx_map_skb() before preparing the TCP pseudo
checksum (ionic_tx_tcp_[inner_]pseudo_csum()), which may perform
skb_cow_head() and might modifies bytes in the linear header area.
Mapping first and then mutating the header risks:
- Using a stale DMA address if skb_cow_head() relocates the head, and/or
- Device reading stale header bytes on weakly-ordered systems
(CPU writes after mapping are not guaranteed visible without an
explicit dma_sync_single_for_device()).
Reorder the TX path to perform all header mutations (including
skb_cow_head()) *before* DMA mapping. Mapping is now done only after the
skb layout and header contents are final. This removes the need for any
post-mapping dma_sync and prevents on-wire corruption observed under
VLAN+TSO load after repeated runs.
This change is purely an ordering fix; no functional behavior change
otherwise.

[ Upstream commit e120f46768d98151ece8756ebd688b0e43dc8b29 ]
Raw IP packets have no MAC header, leaving skb->mac_header uninitialized.
This can trigger kernel panics on ARM64 when xfrm or other subsystems
access the offset due to strict alignment checks.
Initialize the MAC header to prevent such crashes.
This can trigger kernel panics on ARM when running IPsec over the
qmimux0 interface.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shruti Parab <shruti.parab@broadcom.com>
[ Upstream commit 0b350b4927e69d66629099dbb32cad8d2d56a26d ]
Add a new bit to struct bnxt_ctx_mem_type to indicate that host
memory has been successfully allocated for this context memory type.
In the next patches, we'll be adding some additional context memory
types for FW debugging/logging. If memory cannot be allocated for
any of these new types, we will not abort and the cleared mem_valid
bit will indicate to skip configuring the memory type.

[ Upstream commit 968d2cc07c2fc9a508a53bd2de61200f50206fbc ]
Add a new function bnxt_free_one_ctx_mem() to free one context
memory type. bnxt_free_ctx_mem() now calls the new function in
the loop to free each context memory type. There is no change in
behavior. Later patches will further make use of the new function.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hongguang Gao <hongguang.gao@broadcom.com>
[ Upstream commit 46010d43ab7b18fbc8a3a0bf4d65c775f8d2adbd ]
If 'force' is false, it will keep the memory pages and all data
structures for the context memory type if the memory is valid.
This patch always passes true for the 'force' parameter so there is
no change in behavior. Later patches will adjust the 'force' parameter
for the FW log context memory types so that the logs will not be reset
after FW reset.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Martin Willi <martin@strongswan.org>
[ Upstream commit c74619e7602e88a0239cd4999571dd31081e9adf ]
hwsim radios marked destroy_on_close are removed when the Netlink socket
that created them is closed. As the portid is not unique across network
namespaces, closing a socket in one namespace may remove radios in another
if it has the destroy_on_close flag set.
Instead of matching the network namespace, match the netgroup of the radio
to limit radio removal to those that have been created by the closing
Netlink socket. The netgroup of a radio identifies the network namespace
it was created in, and matching on it removes a destroy_on_close radio
even if it has been moved to another namespace.
Fixes: 100cb9ff40e0 ("mac80211_hwsim: Allow managing radios from non-initial namespaces")

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gal Pressman <gal@nvidia.com>
[ Upstream commit d1c94bc5b90c21b65469d30d4a6bc8ed715c1bfe ]
mlx5e_get_module_eeprom_by_page() has weird error handling.
First, it is treating -EINVAL as a special case, but it is unclear why.
Second, it tries to fail "gracefully" by returning the number of bytes
read even in case of an error. This results in wrongly returning
success (0 return value) if the error occurs before any bytes were
read.
Simplify the error handling by returning an error when such occurs. This
also aligns with the error handling we have in mlx5e_get_module_eeprom()
for the old API.
This fixes the following case where the query fails, but userspace
ethtool wrongly treats it as success and dumps an output:
# ethtool -m eth2
netlink warning: mlx5_core: Query module eeprom by page failed, read 0 bytes, err -5

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meghana Malladi <m-malladi@ti.com>
[ Upstream commit ae4789affd1e181ae46e72e2b5fbe2d6d7b6616a ]
The ICSSG driver does the initial FDB configuration which
includes setting the control registers. Other run time
management like learning is managed by the PRU's. The default
FDB hash size used by the firmware is 512 slots, which is
currently missing in the current driver. Update the driver
FDB config to include FDB hash size as well.
Please refer trm [1] 6.4.14.12.17 section on how the FDB config
register gets configured. From the table 6-1404, there is a reset
field for FDB_HAS_SIZE which is 4, meaning 1024 slots. Currently
the driver is not updating this reset value from 4(1024 slots) to
3(512 slots). This patch fixes this by updating the reset value
to 512 slots.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dragos Tatulea <dtatulea@nvidia.com>
[ Upstream commit bacd8d80181ebe34b599a39aa26bf73a44c91e55 ]
mlx5e_hw_gro_skb_has_enough_space() uses a formula to check if there is
enough space in the skb frags to store more data. This formula is
incorrect for 64K page sizes and it triggers early GRO session
termination because the first fragment will blow up beyond
GRO_LEGACY_MAX_SIZE.
This patch adds a special case for page sizes >= GRO_LEGACY_MAX_SIZE
(64K) which uses the skb->len instead. Within this context,
the check is safe from fragment overflow because the hardware
will continuously fill the data up to the reservation size of 64K
and the driver will coalesce all data from the same page to the same
fragment. This means that the data will span one fragment or at most
two for such a large page size.
It is expected that the if statement will be optimized out as the
check is done with constants.

From: Haotian Zhang <vulab@iscas.ac.cn>
[ Upstream commit 4d6ec3a7932ca5b168426f7b5b40abab2b41d2da ]
The driver calls mfd_add_devices() but fails to call mfd_remove_devices()
in error paths after successful MFD device registration and in the remove
function. This leads to resource leaks where MFD child devices are not
properly unregistered.
Replace mfd_add_devices with devm_mfd_add_devices to automatically
manage the device resources.

From: Tristram Ha <tristram.ha@microchip.com>
[ Upstream commit 96baf482ca1f69f0da9d10a5bd8422c87ea9039e ]
KSZ9477/KSZ9897 and LAN937X families of switches use a reserved multicast
address table for some specific forwarding with some multicast addresses,
like the one used in STP. The hardware assumes the host port is the last
port in KSZ9897 family and port 5 in LAN937X family. Most of the time
this assumption is correct but not in other cases like KSZ9477.
Originally the function just setups the first entry, but the others still
need update, especially for one common multicast address that is used by
PTP operation.
LAN937x also uses different register bits when accessing the reserved
table.

It seems that we are using a mutex in a atomic context which is wrong.
Change the mutex with a spinlock.

------------------
From: Nikolay Aleksandrov <razor@blackwall.org>
[ Upstream commit 8dca36978aa80bab9d4da130c211db75c9e00048 ]
syzbot reported[1] a use-after-free when deleting an expired fdb. It is
due to a race condition between learning still happening and a port being
deleted, after all its fdbs have been flushed. The port's state has been
toggled to disabled so no learning should happen at that time, but if we
have MST enabled, it will bypass the port's state, that together with VLAN
filtering disabled can lead to fdb learning at a time when it shouldn't
happen while the port is being deleted. VLAN filtering must be disabled
because we flush the port VLANs when it's being deleted which will stop
learning. This fix adds a check for the port's vlan group which is
initialized to NULL when the port is getting deleted, that avoids the port
state bypass. When MST is enabled there would be a minimal new overhead
in the fast-path because the port's vlan group pointer is cache-hot.

From: Nikolay Aleksandrov <razor@blackwall.org>
[ Upstream commit ee87c63f9b2a418f698d79c2991347e31a7d2c27 ]
As Ido pointed out, the static key usage in MST is buggy and should use
inc/dec instead of enable/disable because we can have multiple bridges
with MST enabled which means a single bridge can disable MST for all.
Use static_branch_inc/dec to avoid that. When destroying a bridge decrement
the key if MST was enabled.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zilin Guan <zilin@seu.edu.cn>
[ Upstream commit 80f0d631dcc76ee1b7755bfca1d8417d91d71414 ]
The function create_field_var() allocates memory for 'val' through
create_hist_field() inside parse_atom(), and for 'var' through
create_var(), which in turn allocates var->type and var->var.name
internally. Simply calling kfree() to release these structures will
result in memory leaks.
Use destroy_hist_field() to properly free 'val', and explicitly release
the memory of var->type and var->var.name before freeing 'var' itself.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wayne Lin <Wayne.Lin@amd.com>
commit 3c6a743c6961cc2cab453b343bb157d6bbbf8120 upstream.
[Why]
drm_dp_mst_topology_queue_probe() is used under the assumption that
mst is already initialized. If we connect system with SST first
then switch to the mst branch during suspend, we will fail probing
topology by calling the wrong API since the mst manager is yet to
be initialized.
[How]
At dm_resume(), once it's detected as mst branc connected, check if
the mst is initialized already. If not, call
dm_helpers_dp_mst_start_top_mgr() instead to initialize mst
V2: Adjust the commit msg a bit

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>
commit 487df8b698345dd5a91346335f05170ed5f29d4e upstream.
The Mesa issue referenced below pointed out a possible deadlock:
[ 1231.611031] Possible interrupt unsafe locking scenario:
[ 1231.611033] CPU0 CPU1
[ 1231.611034] ---- ----
[ 1231.611035] lock(&xa->xa_lock#17);
[ 1231.611038] local_irq_disable();
[ 1231.611039] lock(&fence->lock);
[ 1231.611041] lock(&xa->xa_lock#17);
[ 1231.611044] <Interrupt>
[ 1231.611045] lock(&fence->lock);
[ 1231.611047]
*** DEADLOCK ***
In this example, CPU0 would be any function accessing job->dependencies
through the xa_* functions that don't disable interrupts (eg:
drm_sched_job_add_dependency(), drm_sched_entity_kill_jobs_cb()).
CPU1 is executing drm_sched_entity_kill_jobs_cb() as a fence signalling
callback so in an interrupt context. It will deadlock when trying to
grab the xa_lock which is already held by CPU0.
Replacing all xa_* usage by their xa_*_irq counterparts would fix
this issue, but Christian pointed out another issue: dma_fence_signal
takes fence.lock and so does dma_fence_add_callback.
dma_fence_signal() // locks f1.lock
-> drm_sched_entity_kill_jobs_cb()
-> foreach dependencies
-> dma_fence_add_callback() // locks f2.lock
This will deadlock if f1 and f2 share the same spinlock.
To fix both issues, the code iterating on dependencies and re-arming them
is moved out to drm_sched_entity_kill_jobs_work().

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ilia Gavrilov <Ilia.Gavrilov@infotecs.ru>
commit 8d59fba49362c65332395789fd82771f1028d87e upstream.
In the parse_adv_monitor_pattern() function, the value of
the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
The size of the 'value' array in the mgmt_adv_pattern structure is 31.
If the value of 'pattern[i].length' is set in the user space
and exceeds 31, the 'patterns[i].value' array can be accessed
out of bound when copied.
Increasing the size of the 'value' array in
the 'mgmt_adv_pattern' structure will break the userspace.
Considering this, and to avoid OOB access revert the limits for 'offset'
and 'length' back to the value of HCI_MAX_AD_LENGTH.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

From: Jason Gunthorpe <jgg@nvidia.com>
commit cb30dfa75d55eced379a42fd67bd5fb7ec38555e upstream.
If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow
to 0 and this triggers divide by 0.
In this case the index should just be 0, so reorganize things to divide
by shift and avoid hitting any overflows.

BUG: spinlock recursion on CPU#0, ifconfig/2420
lock: terminate_lock.2+0x0/0x1c, .magic: dead4ead, .owner: ifconfig/2420, .owner_cpu: 0
While creating the stack trace, the unwinder uses the stack pointer to guess
the previous frame to read the previous stack pointer from memory. The crash
happens, because the unwinder tries to read from unaligned memory and as such
triggers the unalignment trap handler which then leads to the spinlock
recursion and finally to a deadlock.
Fix it by checking the alignment before accessing the memory.

------------------
From: Joshua Rogers <linux@joshua.hu>
commit 4012abe8a78fbb8869634130024266eaef7081fe upstream.
SMB2_change_notify called smb2_validate_iov() but ignored the return
code, then kmemdup()ed using server provided OutputBufferOffset/Length.
Check the return of smb2_validate_iov() and bail out on error.
Discovered with help from the ZeroPath security tooling.

From: Henrique Carvalho <henrique.carvalho@suse.com>
commit 734e99623c5b65bf2c03e35978a0b980ebc3c2f8 upstream.
find_or_create_cached_dir() could grab a new reference after kref_put()
had seen the refcount drop to zero but before cfid_list_lock is acquired
in smb2_close_cached_fid(), leading to use-after-free.
Switch to kref_put_lock() so cfid_release() is called with
cfid_list_lock held, closing that gap.

environments), pipe_ctx->stream_res.tg will be destroyed. Then, reading
odm_combine_segments causes kernel NULL pointer dereference.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bui Quang Minh <minhquangbui99@gmail.com>
commit 0c716703965ffc5ef4311b65cb5d84a703784717 upstream.
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change.

From: Nathan Chancellor <nathan@kernel.org>
commit 2b81082ad37cc3f28355fb73a6a69b91ff7dbf20 upstream.
Commit 2f13daee2a72 ("lib/crypto/curve25519-hacl64: Disable KASAN with
clang-17 and older") inadvertently disabled KASAN in curve25519-hacl64.o
for GCC unconditionally because clang-min-version will always evaluate
to nothing for GCC. Add a check for CONFIG_CC_IS_CLANG to avoid applying
the workaround for GCC, which is only needed for clang-17 and older.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@intel.com>
commit bb44826c3bdbf1fa3957008a04908f45e5666463 upstream.
Intel platforms with UFS, can support Suspend-to-Idle (S0ix) and
Suspend-to-RAM (S3). For S0ix the link state should be HIBERNATE. For
S3, state is lost, so the link state must be OFF. Driver policy,
expressed by spm_lvl, can be 3 (link HIBERNATE, device SLEEP) for S0ix
but must be changed to 5 (link OFF, device POWEROFF) for S3.
Fix support for S0ix/S3 by switching spm_lvl as needed. During suspend
->prepare(), if the suspend target state is not Suspend-to-Idle, ensure
the spm_lvl is at least 5 to ensure that resume will be possible from
deep sleep states. During suspend ->complete(), restore the spm_lvl to
its original value that is suitable for S0ix.
This fix is first needed in Intel Alder Lake based controllers.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@intel.com>
commit d34caa89a132cd69efc48361d4772251546fdb88 upstream.
ufshcd_link_startup() has a facility (link_startup_again) to issue
DME_LINKSTARTUP a 2nd time even though the 1st time was successful.
Some older hardware benefits from that, however the behaviour is
non-standard, and has been found to cause link startup to be unreliable
for some Intel Alder Lake based host controllers.
Add UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE to suppress
link_startup_again, in preparation for setting the quirk for affected
controllers.

6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Melissa Wen <mwen@igalia.com>
commit 2f9c63883730a0bfecb086e6e59246933f936ca1 upstream.
Use `atomic_commit_setup` to change the DC stream state. It's a
preparation to remove from `atomic_check` changes in CRTC color
components of DC stream state and prevent DC to commit TEST_ONLY
changes.

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 92bac7d4de9c07933f6b76d8f1c7f8240f911f4f upstream.
Driver in the probe enables wakeup source conditionally, so the cleanup
path should do the same - do not release the wakeup source memory if it
was not allocated.

From: Punit Agrawal <punit.agrawal@oss.qualcomm.com>
commit 543d35004007a06ef247acf2fc55efa8388aa741 upstream.
Commit 4d330fe54145 ("ACPI: SPCR: Support Precise Baud Rate field")
added support to use the precise baud rate available since SPCR 1.09
(revision 4) but failed to check the version of the table provided by
the firmware.
Accessing an older version of SPCR table causes accesses beyond the
end of the table and can lead to garbage data to be used for the baud
rate.
Check the version of the firmware provided SPCR to ensure that the
precise baudrate is vaild before using it.

commit c83ca5a4df7cf0ce9ccc25e8481043e05aed6ad0 upstream.
genphy_c45_write_eee_adv() becomes a no-op if phydev->supported_eee
is cleared. That's not what we want because this function is still
needed to clear the EEE advertisement register(s).
Fill phydev->eee_broken_modes instead to ensure that userspace
can't re-enable EEE advertising.
