The hw->formats may be set by snd_dmaengine_pcm_refine_runtime_hwparams()
in component's startup()/open(), but soc_pcm_hw_init() will init
hw->formats in dpcm_runtime_setup_fe() after component's startup()/open(),
which causes the valuable hw->formats to be cleared.
So need to store the hw->formats before initialization, then restore
it after initialization.

[ Upstream commit f8acb24aaf89fc46cd953229462ea8abe31b395f ]
Hyper-V should never specify a VM that is a Confidential VM and also
running in the root partition. Nonetheless, explicitly block such a
combination to guard against a compromised Hyper-V maliciously trying to
exploit root partition functionality in a Confidential VM to expose
Confidential VM secrets. No known bug is being fixed, but the attack
surface for Confidential VMs on Hyper-V is reduced.

below error when rmmod -> insmod.

[ Upstream commit 362f0b6678ad1377c322a7dd237ea6785efc7342 ]
When playing with various compilers or their versions, some choke on
the t7xx code. For example (with gcc 13):
In file included from ./arch/s390/include/generated/asm/rwonce.h:1,
from ../include/linux/compiler.h:247,
from ../include/linux/build_bug.h:5,
from ../include/linux/bits.h:22,
from ../drivers/net/wwan/t7xx/t7xx_state_monitor.c:17:
In function 'preempt_count',
inlined from 't7xx_fsm_append_event' at ../drivers/net/wwan/t7xx/t7xx_state_monitor.c:439:43:
../include/asm-generic/rwonce.h:44:26: error: array subscript 0 is outside array bounds of 'const volatile int[0]' [-Werror=array-bounds=]
There is no reason for any code in the kernel to be built with -Werror
by default. Note that we have generic CONFIG_WERROR. So if anyone wants
-Werror, they can enable that.

[ Upstream commit a3d27dfdcfc27ac3f46de5391bb6d24f04af7941 ]
The driver is exiting from the fault watchdog thread if it sees the 0xF002
(Soft reset in progress) fault code.
If the driver initiates the soft reset, then the driver restarts the
watchdog at the end of the soft reset completion. However, if the soft
reset is initiated by the firmware asynchronously, then the driver will
never restart the watchdog and never re-initialize the controller after the
asynchronous soft reset completion.

Add the DMI ids for another variant of the T14s Gen1, which also needs
the s2idle quirk.

Currently ath11k breaks after hibernation, the reason being that ath11k expects
that the wireless device will have power during suspend and the firmware will
continue running. But of course during hibernation the power from the device is
cut off and firmware is not running when resuming, so ath11k will fail.
(The reason why ath11k needs the firmware running is the interaction between
mac80211 and MHI stack, it's a long story and more info in the bugzilla report.)
In SUSE kernels the watchdog timeout is reduced from the default 120 to 60 seconds:
CONFIG_DPM_WATCHDOG_TIMEOUT=60
But as the ath11k MHI timeout is 90 seconds the kernel will crash before will
ath11k will recover in resume callback. To avoid the crash reduce the MHI
timeout to just 20 seconds.

[ Upstream commit f82e7ca019dfad3b006fd3b772f7ac569672db55 ]
A __field() in the TRACE_EVENT() macro is used to set up the fields of the
trace event data. It is for single storage units (word, char, int,
pointer, etc) and not for complex structures or arrays. Unfortunately,
there's nothing preventing the build from accepting:
__field(int, arr[5]);
from building. It will turn into a array value. This use to work fine, as
the offset and size use to be determined by the macro using the field name,
but things have changed and the offset and size are now determined by the
type. So the above would only be size 4, and the next field will be
located 4 bytes from it (instead of 20).
The proper way to declare static arrays is to use the __array() macro.
Instead of __field(int, arr[5]) it should be __array(int, arr, 5).
Add some macro tricks to the building of a trace event from the
TRACE_EVENT() macro such that __field(int, arr[5]) will fail to build. A
comment by the failure will explain why the build failed.

Commit c1d55d50139b ("asm-generic/io.h: Fix sparse warnings on
big-endian architectures") missed fixing the 64-bit accessors.
Arnd explains in the attached link why the casts are necessary, even if
__raw_readq() and __raw_writeq() do not take endian-specific types.

commit 09d4d6da1b65d09414e7bce61459593f3c80ead1 upstream.
When the BIOS has been configured for Fast Boot, systems with mt7921e
have non-functional wifi. Turning on Fast boot caused both bus master
enable and memory space enable bits in PCI_COMMAND not to get configured.
The mt7921 driver already sets bus master enable, but explicitly check
and set memory access enable as well to fix this problem.

commit 2198d07c509f1db4a1185d1f65aaada794c6ea59 upstream.
All occurrences of the scs_load macro load the value of the shadow call
stack pointer from the task which is current at that point. So instead
of taking a task struct register argument in the scs_load macro to
specify the task struct to load from, let's always reference the current
task directly. This should make it much harder to exploit any
instruction sequences reloading the shadow call stack pointer register
from memory.

commit 59b37fe52f49955791a460752c37145f1afdcad1 upstream.
Instead of reloading the shadow call stack pointer from the ordinary
stack, which may be vulnerable to the kind of gadget based attacks
shadow call stacks were designed to prevent, let's store a task's shadow
call stack pointer in the task struct when switching to the shadow IRQ
stack.
Given that currently, the task_struct::scs_sp field is only used to
preserve the shadow call stack pointer while a task is scheduled out or
running in user space, reusing this field to preserve and restore it
while running off the IRQ stack must be safe, as those occurrences are
guaranteed to never overlap. (The stack switching logic only switches
stacks when running from the task stack, and so the value being saved
here always corresponds to the task mode shadow stack)
While at it, fold a mov/add/mov sequence into a single add.

From: Lukas Wunner <lukas@wunner.de>
commit f5eff5591b8f9c5effd25c92c758a127765f74c1 upstream.
In 2013, commits
2e35afaefe64 ("PCI: pciehp: Add reset_slot() method")
608c388122c7 ("PCI: Add slot reset option to pci_dev_reset()")
amended PCIe hotplug to mask Presence Detect Changed events during a
Secondary Bus Reset. The reset thus no longer causes gratuitous slot
bringdown and bringup.
However the commits neglected to serialize reset with code paths reading
slot registers. For instance, a slot bringup due to an earlier hotplug
event may see the Presence Detect State bit cleared during a concurrent
Secondary Bus Reset.
In 2018, commit
5b3f7b7d062b ("PCI: pciehp: Avoid slot access during reset")
retrofitted the missing locking. It introduced a reset_lock which
serializes a Secondary Bus Reset with other parts of pciehp.
Unfortunately the locking turns out to be overzealous: reset_lock is
held for the entire enumeration and de-enumeration of hotplugged devices,
including driver binding and unbinding.
Driver binding and unbinding acquires device_lock while the reset_lock
of the ancestral hotplug port is held. A concurrent Secondary Bus Reset
acquires the ancestral reset_lock while already holding the device_lock.
The asymmetric locking order in the two code paths can lead to AB-BA
deadlocks.
Michael Haeuptle reports such deadlocks on simultaneous hot-removal and
vfio release (the latter implies a Secondary Bus Reset):
pciehp_ist() # down_read(reset_lock)
pciehp_handle_presence_or_link_change()
pciehp_disable_slot()
__pciehp_disable_slot()
remove_board()
pciehp_unconfigure_device()
pci_stop_and_remove_bus_device()
pci_stop_bus_device()
pci_stop_dev()
device_release_driver()
device_release_driver_internal()
__device_driver_lock() # device_lock()
SYS_munmap()
vfio_device_fops_release()
vfio_device_group_close()
vfio_device_close()
vfio_device_last_close()
vfio_pci_core_close_device()
vfio_pci_core_disable() # device_lock()
__pci_reset_function_locked()
pci_reset_bus_function()
pci_dev_reset_slot_function()
pci_reset_hotplug_slot()
pciehp_reset_slot() # down_write(reset_lock)
Ian May reports the same deadlock on simultaneous hot-removal and an
AER-induced Secondary Bus Reset:
aer_recover_work_func()
pcie_do_recovery()
aer_root_reset()
pci_bus_error_reset()
pci_slot_reset()
pci_slot_lock() # device_lock()
pci_reset_hotplug_slot()
pciehp_reset_slot() # down_write(reset_lock)
Fix by releasing the reset_lock during driver binding and unbinding,
thereby splitting and shrinking the critical section.
Driver binding and unbinding is protected by the device_lock() and thus
serialized with a Secondary Bus Reset. There's no need to additionally
protect it with the reset_lock. However, pciehp does not bind and
unbind devices directly, but rather invokes PCI core functions which
also perform certain enumeration and de-enumeration steps.
The reset_lock's purpose is to protect slot registers, not enumeration
and de-enumeration of hotplugged devices. That would arguably be the
job of the PCI core, not the PCIe hotplug driver. After all, an
AER-induced Secondary Bus Reset may as well happen during boot-time
enumeration of the PCI hierarchy and there's no locking to prevent that
either.
Exempting *de-enumeration* from the reset_lock is relatively harmless:
A concurrent Secondary Bus Reset may foil config space accesses such as
PME interrupt disablement. But if the device is physically gone, those
accesses are pointless anyway. If the device is physically present and
only logically removed through an Attention Button press or the sysfs
"power" attribute, PME interrupts as well as DMA cannot come through
because pciehp_unconfigure_device() disables INTx and Bus Master bits.
That's still protected by the reset_lock in the present commit.
Exempting *enumeration* from the reset_lock also has limited impact:
The exempted call to pci_bus_add_device() may perform device accesses
through pcibios_bus_add_device() and pci_fixup_device() which are now
no longer protected from a concurrent Secondary Bus Reset. Otherwise
there should be no impact.
In essence, the present commit seeks to fix the AB-BA deadlocks while
still retaining a best-effort reset protection for enumeration and
de-enumeration of hotplugged devices -- until a general solution is
implemented in the PCI core.

Qcom PCIe IP version v2.7.0 and its derivatives don't contain the
PCIE20_PARF_AXI_MSTR_WR_ADDR_HALT register. Instead, they have the new
PCIE20_PARF_AXI_MSTR_WR_ADDR_HALT_V2 register. So fix the incorrect
register usage which is modifying a different register.
Also in this IP version, this register change doesn't depend on MSI
being enabled. So remove that check also.

commit 14853a0676c126aad836eb249499552fa9d6e85a upstream.
This reverts commit 2d5253a096c6057bbf7caa5520856dcdf7eca8bb.
There are 2 commits with commit message "Add a secondary AT port to Telit
FN990":
commit 2d5253a096c6 ("bus: mhi: host: pci_generic: Add a secondary AT port
to Telit FN990")
commit 479aa3b0ec2e ("bus: mhi: host: pci_generic: Add a secondary AT port
to Telit FN990")
This turned out to be due to the patch getting applied through different
trees and git settled on a resolution while applying it second time. But
the second AT port of Foxconn devices don't work in PCIe mode. So the
second commit needs to be reverted.

From: Randy Dunlap <rdunlap@infradead.org>
commit 644f17412f5acf01a19af9d04a921937a2bc86c6 upstream.
UML supports HAS_IOMEM since 0bbadafdc49d (um: allow disabling
NO_IOMEM).
Current IMA build on UML fails on allmodconfig (with TCG_TPM=m):
ld: security/integrity/ima/ima_queue.o: in function `ima_add_template_entry':
ima_queue.c:(.text+0x2d9): undefined reference to `tpm_pcr_extend'
ld: security/integrity/ima/ima_init.o: in function `ima_init':
ima_init.c:(.init.text+0x43f): undefined reference to `tpm_default_chip'
ld: security/integrity/ima/ima_crypto.o: in function `ima_calc_boot_aggregate_tfm':
ima_crypto.c:(.text+0x1044): undefined reference to `tpm_pcr_read'
ld: ima_crypto.c:(.text+0x10d8): undefined reference to `tpm_pcr_read'
Modify the IMA Kconfig entry so that it selects TCG_TPM if HAS_IOMEM
is set, regardless of the UML Kconfig setting.
This updates TCG_TPM from =m to =y and fixes the linker errors.

From: Sascha Hauer <s.hauer@pengutronix.de>
commit a6f187f92bcc2b17821538b4a11d61764e68b091 upstream.
The RTW88 chipsets have four different priority queues in hardware. For
the USB type chipsets the packets destined for a specific priority queue
must be sent through the endpoint corresponding to the queue. This was
not fully understood when porting from the RTW88 USB out of tree driver
and thus violated.
This patch implements the qsel to endpoint mapping as in
get_usb_bulkout_id_88xx() in the downstream driver.
Without this the driver often issues "timed out to flush queue 3"
warnings and often TX stalls completely.

From: Badhri Jagan Sridharan <badhri@google.com>
commit 0db213ea8eed5534a5169e807f28103cbc9d23df upstream.
usb_udc_connect_control does not check to see if the udc has already
been started. This causes gadget->ops->pullup to be called through
usb_gadget_connect when invoked from usb_udc_vbus_handler even before
usb_gadget_udc_start is called. Guard this by checking for udc->started
in usb_udc_connect_control before invoking usb_gadget_connect.
Guarding udc->vbus, udc->started, gadget->connect, gadget->deactivate
related functions with connect_lock. usb_gadget_connect_locked,
usb_gadget_disconnect_locked, usb_udc_connect_control_locked,
usb_gadget_udc_start_locked, usb_gadget_udc_stop_locked are called with
this lock held as they can be simulataneously invoked from different code
paths.
Adding an additional check to make sure udc is started(udc->started)
before pullup callback is invoked.

commit a3afbf5cc887fc3401f012fe629810998ed61859 upstream.
usb_gadget_connect calls gadget->ops->pullup without checking whether
gadget->connected was previously set. Make this symmetric to
usb_gadget_disconnect by returning early if gadget->connected is
already set.

From: Wesley Cheng <quic_wcheng@quicinc.com>
commit 02435a739b81ae24aff5d6e930efef9458e2af3c upstream.
It was observed that there are hosts that may complete pending SETUP
transactions before the stop active transfers and controller halt occurs,
leading to lingering endxfer commands on DEPs on subsequent pullup/gadget
start iterations.
dwc3_gadget_ep_disable name=ep8in flags=0x3009 direction=1
dwc3_gadget_ep_disable name=ep4in flags=1 direction=1
dwc3_gadget_ep_disable name=ep3out flags=1 direction=0
usb_gadget_disconnect deactivated=0 connected=0 ret=0
The sequence shows that the USB gadget disconnect (dwc3_gadget_pullup(0))
routine completed successfully, allowing for the USB gadget to proceed with
a USB gadget connect. However, if this occurs the system runs into an
issue where:
BUG: spinlock already unlocked on CPU
spin_bug+0x0
dwc3_remove_requests+0x278
dwc3_ep0_out_start+0xb0
__dwc3_gadget_start+0x25c
This is due to the pending endxfers, leading to gadget start (w/o lock
held) to execute the remove requests, which will unlock the dwc3
spinlock as part of giveback.
To mitigate this, resolve the pending endxfers on the pullup disable
path by re-locating the SETUP phase check after stop active transfers, since
that is where the DWC3_EP_DELAY_STOP is potentially set. This also allows
for handling of a host that may be unresponsive by using the completion
timeout to trigger the stall and restart for EP0.

Spec says, when CUR_TEMP_TJ_SEL == 3 and CUR_TEMP_RANGE_SEL == 0,
it should use RangeUnadjusted is 0, which is (CurTmp*0.125 -49) C. The
CUR_TEMP register is read-write when CUR_TEMP_TJ_SEL == 3 (bit 17-16).
Add the check to detect it.

On DT unaware platforms of_property_read_u32_array() returns -ENOSYS
which wasn't handled by the code treating adi,pwm-active-state as
optional. Update the code to use device_property_read_u32_array() which
deals gracefully with DT unaware platforms.

commit f7abf14f0001a5a47539d9f60bbdca649e43536b upstream.
For some unknown reason the introduction of the timer_wait_running callback
missed to fixup posix CPU timers, which went unnoticed for almost four years.
Marco reported recently that the WARN_ON() in timer_wait_running()
triggers with a posix CPU timer test case.
Posix CPU timers have two execution models for expiring timers depending on
CONFIG_POSIX_CPU_TIMERS_TASK_WORK:
1) If not enabled, the expiry happens in hard interrupt context so
spin waiting on the remote CPU is reasonably time bound.
Implement an empty stub function for that case.
2) If enabled, the expiry happens in task work before returning to user
space or guest mode. The expired timers are marked as firing and moved
from the timer queue to a local list head with sighand lock held. Once
the timers are moved, sighand lock is dropped and the expiry happens in
fully preemptible context. That means the expiring task can be scheduled
out, migrated, interrupted etc. So spin waiting on it is more than
suboptimal.
The timer wheel has a timer_wait_running() mechanism for RT, which uses
a per CPU timer-base expiry lock which is held by the expiry code and the
task waiting for the timer function to complete blocks on that lock.
This does not work in the same way for posix CPU timers as there is no
timer base and expiry for process wide timers can run on any task
belonging to that process, but the concept of waiting on an expiry lock
can be used too in a slightly different way:
- Add a mutex to struct posix_cputimers_work. This struct is per task
and used to schedule the expiry task work from the timer interrupt.
- Add a task_struct pointer to struct cpu_timer which is used to store
a the task which runs the expiry. That's filled in when the task
moves the expired timers to the local expiry list. That's not
affecting the size of the k_itimer union as there are bigger union
members already
- Let the task take the expiry mutex around the expiry function
- Let the waiter acquire a task reference with rcu_read_lock() held and
block on the expiry mutex
This avoids spin-waiting on a task which might not even be on a CPU and
works nicely for RT too.

commit 5a4e1b5aed2a36a10d6a3b30fafb6b3bf41c3186 upstream.
It the device is probed in non-zero ACPI D state, the module
identification is delayed until the first streamon.
The module identification has two parts: deviceID and version. To rea
the version we have to enable OTP read. This cannot be done during
streamon, becase it modifies REG_MODE_SELECT.
Since the driver has the same behaviour for all the module versions, do
not read the module version from the sensor's OTP.

commit a37a512db3fa1b65fe9087003e5b2072cefb3667 upstream.
Legacy Display Unit (LDU) fb dirty support used a custom fb dirty callback. Latter
handled only the DIRTYFB IOCTL presentation path but not the ADDFB2/PAGE_FLIP/RMFB
IOCTL path, common for Wayland compositors.
Get rid of the custom callback in favor of drm_atomic_helper_dirtyfb and unify the
handling of the presentation paths inside of vmw_ldu_primary_plane_atomic_update.
This also homogenizes the fb dirty callbacks across all DUs: LDU, SOU and STDU.

From: Chengming Zhou <zhouchengming@bytedance.com>
commit 20de765f6d9da0c47b756429c60b41063b990a10 upstream.
We need to set QUEUE_FLAG_STATS for two cases:
1. blk_stat_enable_accounting()
2. blk_stat_add_callback()
So we should clear it only when ((q->stats->accounting == 0) &&
list_empty(&q->stats->callbacks)).
blk_stat_disable_accounting() only check if q->stats->accounting
is 0 before clear the flag, this patch fix it.
Also add list_empty(&q->stats->callbacks)) check when enable, or
the flag is already set.
The bug can be reproduced on kernel without BLK_DEV_THROTTLING
(since it unconditionally enable accounting, see the next patch).
# cat /sys/block/sr0/queue/scheduler
none mq-deadline [bfq]
# cat /sys/kernel/debug/block/sr0/state
SAME_COMP|IO_STAT|INIT_DONE|STATS|REGISTERED|NOWAIT|30
# echo none > /sys/block/sr0/queue/scheduler
# cat /sys/kernel/debug/block/sr0/state
SAME_COMP|IO_STAT|INIT_DONE|REGISTERED|NOWAIT
# cat /sys/block/sr0/queue/wbt_lat_usec
75000
We can see that after changing elevator from "bfq" to "none",
"STATS" flag is lost even though WBT callback still need it.

From: Eric Biggers <ebiggers@google.com>
commit 9cd1e566676bbcb8a126acd921e4e194e6339603 upstream.
Once all I/O using a blk_crypto_key has completed, filesystems can call
blk_crypto_evict_key(). However, the block layer currently doesn't call
blk_crypto_put_keyslot() until the request is being freed, which happens
after upper layers have been told (via bio_endio()) the I/O has
completed. This causes a race condition where blk_crypto_evict_key()
can see 'slot_refs != 0' without there being an actual bug.
This makes __blk_crypto_evict_key() hit the
'WARN_ON_ONCE(atomic_read(&slot->slot_refs) != 0)' and return without
doing anything, eventually causing a use-after-free in
blk_crypto_reprogram_all_keys(). (This is a very rare bug and has only
been seen when per-file keys are being used with fscrypt.)
There are two options to fix this: either release the keyslot before
bio_endio() is called on the request's last bio, or make
__blk_crypto_evict_key() ignore slot_refs. Let's go with the first
solution, since it preserves the ability to report bugs (via
WARN_ON_ONCE) where a key is evicted while still in-use.

commit 70493a63ba04f754f7a7dd53a4fcc82700181490 upstream.
blk_crypto_evict_key() is only called in contexts such as inode eviction
where failure is not an option. So there is nothing the caller can do
with errors except log them. (dm-table.c does "use" the error code, but
only to pass on to upper layers, so it doesn't really count.)
Just make blk_crypto_evict_key() return void and log errors itself.

commit 5c7cb94452901a93e90c2230632e2c12a681bc92 upstream.
If blk_crypto_evict_key() sees that the key is still in-use (due to a
bug) or that ->keyslot_evict failed, it currently just returns while
leaving the key linked into the keyslot management structures.
However, blk_crypto_evict_key() is only called in contexts such as inode
eviction where failure is not an option. So actually the caller
proceeds with freeing the blk_crypto_key regardless of the return value
of blk_crypto_evict_key().
These two assumptions don't match, and the result is that there can be a
use-after-free in blk_crypto_reprogram_all_keys() after one of these
errors occurs. (Note, these errors *shouldn't* happen; we're just
talking about what happens if they do anyway.)
Fix this by making blk_crypto_evict_key() unlink the key from the
keyslot management structures even on failure.
Also improve some comments.

commit 094fb49a2d0d6827c86d2e0840873e6db0c491d2 upstream.
If userspace races tcsetattr() with a write, the drained condition
might not be guaranteed by the kernel. There is a race window after
checking Tx is empty before tty_set_termios() takes termios_rwsem for
write. During that race window, more characters can be queued by a
racing writer.
Any ongoing transmission might produce garbage during HW's
->set_termios() call. The intent of TCSADRAIN/FLUSH seems to be
preventing such a character corruption. If those flags are set, take
tty's write lock to stop any writer before performing the lower layer
Tx empty check and wait for the pending characters to be sent (if any).
The initial wait for all-writers-done must be placed outside of tty's
write lock to avoid deadlock which makes it impossible to use
tty_wait_until_sent(). The write lock is retried if a racing write is
detected.

commit 146a37e05d620cef4ad430e5d1c9c077fe6fa76f upstream.
There's a potential race before THRE/TEMT deasserts when DMA Tx is
starting up (or the next batch of continuous Tx is being submitted).
This can lead to misdetecting Tx empty condition.
It is entirely normal for THRE/TEMT to be set for some time after the
DMA Tx had been setup in serial8250_tx_dma(). As Tx side is definitely
not empty at that point, it seems incorrect for serial8250_tx_empty()
claim Tx is empty.
Fix the race by also checking in serial8250_tx_empty() whether there's
DMA Tx active.
Note: This fix only addresses in-kernel race mainly to make using
TCSADRAIN/FLUSH robust. Userspace can still cause other races but they
seem userspace concurrency control problems.

From: Jan Kundrát <jan.kundrat@cesnet.cz>
commit 3f42b142ea1171967e40e10e4b0241c0d6d28d41 upstream.
After upgrading from 5.16 to 6.1, our board with a MAX14830 started
producing lots of garbage data over UART. Bisection pointed out commit
285e76fc049c as the culprit. That patch tried to replace hand-written
code which I added in 2b4bac48c1084 ("serial: max310x: Use batched reads
when reasonably safe") with the generic regmap infrastructure for
batched operations.
Unfortunately, the `regmap_raw_read` and `regmap_raw_write` which were
used are actually functions which perform IO over *multiple* registers.
That's not what is needed for accessing these Tx/Rx FIFOs; the
appropriate functions are the `_noinc_` versions, not the `_raw_` ones.
Fix this regression by using `regmap_noinc_read()` and
`regmap_noinc_write()` along with the necessary `regmap_config` setup;
with this patch in place, our board communicates happily again. Since
our board uses SPI for talking to this chip, the I2C part is completely
untested.
Fixes: 285e76fc049c ("serial: max310x: use regmap methods for SPI batch operations")

commit 58d7668242647e661a20efe065519abd6454287e upstream.
For CONFIG_NO_HZ_FULL systems, the tick_do_timer_cpu cannot be offlined.
However, cpu_is_hotpluggable() still returns true for those CPUs. This causes
torture tests that do offlining to end up trying to offline this CPU causing
test failures. Such failure happens on all architectures.
Fix the repeated error messages thrown by this (even if the hotplug errors are
harmless) by asking the opinion of the nohz subsystem on whether the CPU can be
hotplugged.
[ Apply Frederic Weisbecker feedback on refactoring tick_nohz_cpu_down(). ]

commit e3184de9d46c2eebdb776face2e2662c6733331d upstream.
'obj-$(CONFIG_SYSCTL) += sysctls.o' must be moved after "obj-y :=",
or it won't be built as it is overwrited.
Note that there is nothing that is going to break by linking
sysctl.o later, we were just being way to cautious and patches
have been updated to reflect these considerations and sent for
stable as well with the whole "base" stuff needing to be linked
prior to child sysctl tables that use that directory. All of
the kernel sysctl APIs always share the same directory, and races
against using it should end up re-using the same single created
directory.
And so something we can do eventually is do away with all the base stuff.
For now it's fine, it's not creating an issue. It is just a bit pedantic
and careful.

Check if first entry exist before running strchr to avoid

From: Zhang Yuchen <zhangyuchen.lcr@bytedance.com>
commit 6d2555cde2918409b0331560e66f84a0ad4849c6 upstream.
The ipmi communication is not restored after a specific version of BMC is
upgraded on our server.
The ipmi driver does not respond after printing the following log:
ipmi_ssif: Invalid response getting flags: 1c 1
I found that after entering this branch, ssif_info->ssif_state always
holds SSIF_GETTING_FLAGS and never return to IDLE.
As a result, the driver cannot be loaded, because the driver status is
checked during the unload process and must be IDLE in shutdown_ssif():
while (ssif_info->ssif_state != SSIF_IDLE)
schedule_timeout(1);
The process trigger this problem is:
1. One msg timeout and next msg start send, and call
ssif_set_need_watch().
2. ssif_set_need_watch()->watch_timeout()->start_flag_fetch() change
ssif_state to SSIF_GETTING_FLAGS.
3. In msg_done_handler() ssif_state == SSIF_GETTING_FLAGS, if an error
message is received, the second branch does not modify the ssif_state.
4. All retry action need IS_SSIF_IDLE() == True. Include retry action in
watch_timeout(), msg_done_handler(). Sending msg does not work either.
SSIF_IDLE is also checked in start_next_msg().
5. The only thing that can be triggered in the SSIF driver is
watch_timeout(), after destory_user(), this timer will stop too.
So, if enter this branch, the ssif_state will remain SSIF_GETTING_FLAGS
and can't send msg, no timer started, can't unload.
We did a comparative test before and after adding this patch, and the
result is effective.

The ADC conversion procedure requires several device I/O operations
performed in a particular sequence. If stx104_read_raw() is called
concurrently, the ADC conversion procedure could be clobbered. Prevent
such a race condition by utilizing a mutex.

commit 9740827468cea80c42db29e7171a50e99acf7328 upstream.
The priv->chan_out_states array and actual DAC value can become
mismatched if stx104_write_raw() is called concurrently. Prevent such a
race condition by utilizing a mutex.

commit b69edab47f1da8edd8e7bfdf8c70f51a2a5d89fb upstream.
Under CONFIG_FORTIFY_SOURCE, memcpy() will check the size of destination
and source buffers. Defining kernel_headers_data as "char" would trip
this check. Since these addresses are treated as byte arrays, define
them as arrays (as done everywhere else).
This was seen with:
$ cat /sys/kernel/kheaders.tar.xz >> /dev/null
detected buffer overflow in memcpy

commit eb411c0cf59ae6344b34bc6f0d298a22b300627e upstream.
This fix is basically the same as 9bce02ef0dfa ("pwm: meson: Fix the
G12A AO clock parents order"). Vendor driver referenced there has
xtal as first parent also for axg ao. In addition fix the name
of the aoclk81 clock. Apparently name aoclk81 as used by the vendor
driver was changed when mainlining the axg clock driver.

As per Hardware Programming Guide, when configuring pin as output,
set the pin value before setting output-enable (OE). Similar approach
is in main SoC TLMM pin controller.

commit 7c339fb4d8577792378136c15fde773cfb863cb8 upstream.
In ring_buffer_reset_online_cpus, the buffer_size_kb write operation
may permanently fail if the cpu_online_mask changes between two
for_each_online_buffer_cpu loops. The number of increases and decreases
on both cpu_buffer->resize_disabled and cpu_buffer->record_disabled may be
inconsistent, causing some CPUs to have non-zero values for these atomic
variables after the function returns.
This issue can be reproduced by "echo 0 > trace" while hotplugging cpu.
After reproducing success, we can find out buffer_size_kb will not be
functional anymore.
To prevent leaving 'resize_disabled' and 'record_disabled' non-zero after
ring_buffer_reset_online_cpus returns, we ensure that each atomic variable
has been set up before atomic_sub() to it.

commit 675751bb20634f981498c7d66161584080cc061e upstream.
If something was written to the buffer just before destruction,
it may be possible (maybe not in a real system, but it did
happen in ARCH=um with time-travel) to destroy the ringbuffer
before the IRQ work ran, leading this KASAN report (or a crash
without KASAN):

From: Toke Høiland-Jørgensen <toke@redhat.com>
commit a543ada7db729514ddd3ba4efa45f4c7b802ad85 upstream.
The crypto_unregister_alg() function expects callers to ensure that any
algorithm that is unregistered has a refcnt of exactly 1, and issues a
BUG_ON() if this is not the case. However, there are in fact drivers that
will call crypto_unregister_alg() without ensuring that the refcnt has been
lowered first, most notably on system shutdown. This causes the BUG_ON() to
trigger, which prevents a clean shutdown and hangs the system.
To avoid such hangs on shutdown, demote the BUG_ON() in
crypto_unregister_alg() to a WARN_ON() with early return. Cc stable because
this problem was observed on a 6.2 kernel, cf the link below.

commit 47446d7cd42358ca7d7a544f2f7823db03f616ff upstream.
aesbs_ecb_encrypt(), aesbs_ecb_decrypt(), aesbs_xts_encrypt(), and
aesbs_xts_decrypt() are called via indirect function calls. Therefore
they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause
their type hashes to be emitted when the kernel is built with
CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure if
the compiler doesn't happen to optimize out the indirect calls.
Fixes: c50d32859e70 ("arm64: Add types to indirect called assembly functions")

From: Eric Biggers <ebiggers@google.com>
commit f900fde28883602b6c5e1027a6c912b673382aaf upstream.
The performance of the crypto fuzz tests has greatly regressed since
v5.18. When booting a kernel on an arm64 dev board with all software
crypto algorithms and CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled, the
fuzz tests now take about 200 seconds to run, or about 325 seconds with
lockdep enabled, compared to about 5 seconds before.
The root cause is that the random number generation has become much
slower due to commit d4150779e60f ("random32: use real rng for
non-deterministic randomness"). On my same arm64 dev board, at the time
the fuzz tests are run, get_random_u8() is about 345x slower than
prandom_u32_state(), or about 469x if lockdep is enabled.
Lockdep makes a big difference, but much of the rest comes from the
get_random_*() functions taking a *very* slow path when the CRNG is not
yet initialized. Since the crypto self-tests run early during boot,
even having a hardware RNG driver enabled (CONFIG_CRYPTO_DEV_QCOM_RNG in
my case) doesn't prevent this. x86 systems don't have this issue, but
they still see a significant regression if lockdep is enabled.
Converting the "Fully random bytes" case in generate_random_bytes() to
use get_random_bytes() helps significantly, improving the test time to
about 27 seconds. But that's still over 5x slower than before.
This is all a bit silly, though, since the fuzz tests don't actually
need cryptographically secure random numbers. So let's just make them
use a non-cryptographically-secure RNG as they did before. The original
prandom_u32() is gone now, so let's use prandom_u32_state() instead,
with an explicitly managed state, like various other self-tests in the
kernel source tree (rbtree_test.c, test_scanf.c, etc.) already do. This
also has the benefit that no locking is required anymore, so performance
should be even better than the original version that used prandom_u32().
Fixes: d4150779e60f ("random32: use real rng for non-deterministic randomness")

commit c79a3169b9f3633c215b55857eba5921e5b49217 upstream.
A number of platforms are emitting the error:
```ccp: unable to access the device: you might be running a broken BIOS.```
This is expected behavior as CCP is no longer accessible from the PSP's
PCIe BAR so stop trying to probe CCP for 0x1649.

From: Zheng Yejian <zhengyejian1@huawei.com>
commit 7a29fb4a4771124bc61de397dbfc1554dbbcc19c upstream.
Registering a kprobe on __rcu_irq_enter_check_tick() can cause kernel
stack overflow as shown below. This issue can be reproduced by enabling
CONFIG_NO_HZ_FULL and booting the kernel with argument "nohz_full=",
and then giving the following commands at the shell prompt:
# cd /sys/kernel/tracing/
# echo 'p:mp1 __rcu_irq_enter_check_tick' >> kprobe_events
# echo 1 > events/kprobes/enable
This commit therefore adds __rcu_irq_enter_check_tick() to the kprobes
blacklist using NOKPROBE_SYMBOL().
Insufficient stack space to handle exception!

commit d82dcd9e21b77d338dc4875f3d4111f0db314a7c upstream.
Reiserfs sets a security xattr at inode creation time in two stages: first,
it calls reiserfs_security_init() to obtain the xattr from active LSMs;
then, it calls reiserfs_security_write() to actually write that xattr.
Unfortunately, it seems there is a wrong expectation that LSMs provide the
full xattr name in the form 'security.<suffix>'. However, LSMs always
provided just the suffix, causing reiserfs to not write the xattr at all
(if the suffix is shorter than the prefix), or to write an xattr with the
wrong name.
Add a temporary buffer in reiserfs_security_write(), and write to it the
full xattr name, before passing it to reiserfs_xattr_set_handle().
Also replace the name length check with a check that the full xattr name is
not larger than XATTR_NAME_MAX.

commit ba5e770c9698782bc203bbf5cf3b36a77720bdbe upstream.
Commit 054a3ef683a1 ("cpufreq: qcom-hw: Allocate qcom_cpufreq_data
during probe") moved getting memory resource and iomap from
qcom_cpufreq_hw_cpu_init() to the probe function, however it left
untouched cleanup in qcom_cpufreq_hw_cpu_exit().
During device unbind this will lead to doule release of resource and
double iounmap(), first by qcom_cpufreq_hw_cpu_exit() and second via
managed resources:
resource: Trying to free nonexistent resource <0x0000000018593000-0x0000000018593fff>

commit 098f4c061ea10b777033b71c10bd9fd706820ee9 upstream.
Disallow enabling LBR support if the CPU supports architectural LBRs.
Traditional LBR support is absent on CPU models that have architectural
LBRs, and KVM doesn't yet support arch LBRs, i.e. KVM will pass through
non-existent MSRs if userspace enables LBRs for the guest.

commit 4984563823f0034d3533854c1b50e729f5191089 upstream.
Extend VMX's nested intercept logic for emulated instructions to handle
"pause" interception, in quotes because KVM's emulator doesn't filter out
NOPs when checking for nested intercepts. Failure to allow emulation of
NOPs results in KVM injecting a #UD into L2 on any NOP that collides with
the emulator's definition of PAUSE, i.e. on all single-byte NOPs.
For PAUSE itself, honor L1's PAUSE-exiting control, but ignore PLE to
avoid unnecessarily injecting a #UD into L2. Per the SDM, the first
execution of PAUSE after VM-Entry is treated as the beginning of a new
loop, i.e. will never trigger a PLE VM-Exit, and so L1 can't expect any
given execution of PAUSE to deterministically exit.
... the processor considers this execution to be the first execution of
PAUSE in a loop. (It also does so for the first execution of PAUSE at
CPL 0 after VM entry.)
All that said, the PLE side of things is currently a moot point, as KVM
doesn't expose PLE to L1.
Note, vmx_check_intercept() is still wildly broken when L1 wants to
intercept an instruction, as KVM injects a #UD instead of synthesizing a
nested VM-Exit. That issue extends far beyond NOP/PAUSE and needs far
more effort to fix, i.e. is a problem for the future.

From: Oliver Upton <oliver.upton@linux.dev>
commit 0acc7239c20a8401b8968c2adace8f7c9b0295ae upstream.
KVM/arm64 had the lock ordering backwards on vcpu->mutex and kvm->lock
from the very beginning. One such example is the way vCPU resets are
handled: the kvm->lock is acquired while handling a guest CPU_ON PSCI
call.
Add a dedicated lock to serialize writes to kvm_vcpu_arch::{mp_state,
reset_state}. Promote all accessors of mp_state to {READ,WRITE}_ONCE()
as readers do not acquire the mp_state_lock. While at it, plug yet
another race by taking the mp_state_lock in the KVM_SET_MP_STATE ioctl
handler.
As changes to MP state are now guarded with a dedicated lock, drop the
kvm->lock acquisition from the PSCI CPU_ON path. Similarly, move the
reader of reset_state outside of the kvm->lock and instead protect it
with the mp_state_lock. Note that writes to reset_state::reset have been
demoted to regular stores as both readers and writers acquire the
mp_state_lock.
While the kvm->lock inversion still exists in kvm_reset_vcpu(), at least
now PSCI CPU_ON no longer depends on it for serializing vCPU reset.

commit c43120afb5c66a3465c7468f5cf9806a26484cde upstream.
kvm->lock must be taken outside of the vcpu->mutex. Of course, the
locking documentation for KVM makes this abundantly clear. Nonetheless,
the locking order in KVM/arm64 has been wrong for quite a while; we
acquire the kvm->lock while holding the vcpu->mutex all over the shop.
All was seemingly fine until commit 42a90008f890 ("KVM: Ensure lockdep
knows about kvm->lock vs. vcpu->mutex ordering rule") caught us with our
pants down, leading to lockdep barfing:
======================================================
WARNING: possible circular locking dependency detected
6.2.0-rc7+ #19 Not tainted
------------------------------------------------------
qemu-system-aar/859 is trying to acquire lock:
ffff5aa69269eba0 (&host_kvm->lock){+.+.}-{3:3}, at: kvm_reset_vcpu+0x34/0x274
but task is already holding lock:
ffff5aa68768c0b8 (&vcpu->mutex){+.+.}-{3:3}, at: kvm_vcpu_ioctl+0x8c/0xba0
which lock already depends on the new lock.
Add a dedicated lock to serialize writes to VM-scoped configuration from
the context of a vCPU. Protect the register width flags with the new
lock, thus avoiding the need to grab the kvm->lock while holding
vcpu->mutex in kvm_reset_vcpu().

From: Oliver Upton <oliver.upton@linux.dev>
commit 4bba7f7def6f278266dadf845da472cfbfed784e upstream.
There are various bits of VM-scoped data that can only be configured
before the first call to KVM_RUN, such as the hypercall bitmaps and
the PMU. As these fields are protected by the kvm->lock and accessed
while holding vcpu->mutex, this is yet another example of lock
inversion.
Change out the kvm->lock for kvm->arch.config_lock in all of these
instances. Opportunistically simplify the locking mechanics of the
PMU configuration by holding the config_lock for the entirety of
kvm_arm_pmu_v3_set_attr().
Note that this also addresses a couple of bugs. There is an unguarded
read of the PMU version in KVM_ARM_VCPU_PMU_V3_FILTER which could race
with KVM_ARM_VCPU_PMU_V3_SET_PMU. Additionally, until now writes to the
per-vCPU vPMU irq were not serialized VM-wide, meaning concurrent calls
to KVM_ARM_VCPU_PMU_V3_IRQ could lead to a false positive in
pmu_irq_is_valid().

From: Oliver Upton <oliver.upton@linux.dev>
commit f00327731131d1b5aa6a1aa9f50bcf8d620ace4c upstream.
Almost all of the vgic state is VM-scoped but accessed from the context
of a vCPU. These accesses were serialized on the kvm->lock which cannot
be nested within a vcpu->mutex critical section.
Move over the vgic state to using the config_lock. Tweak the lock
ordering where necessary to ensure that the config_lock is acquired
after the vcpu->mutex. Acquire the config_lock in kvm_vgic_create() to
avoid a race between the converted flows and GIC creation. Where
necessary, continue to acquire kvm->lock to avoid a race with vCPU
creation (i.e. flows that use lock_all_vcpus()).
Finally, promote the locking expectations in comments to lockdep
assertions and update the locking documentation for the config_lock as
well as vcpu->mutex.

commit 49e5d16b6fc003407a33a9961b4bcbb970bd1c76 upstream.
commit f00327731131 ("KVM: arm64: Use config_lock to protect vgic
state") was meant to rectify a longstanding lock ordering issue in KVM
where the kvm->lock is taken while holding vcpu->mutex. As it so
happens, the aforementioned commit introduced yet another locking issue
by acquiring the its_lock before acquiring the config lock.
This is obviously wrong, especially considering that the lock ordering
is well documented in vgic.c. Reshuffle the locks once more to take the
config_lock before the its_lock. While at it, sprinkle in the lockdep
hinting that has become popular as of late to keep lockdep apprised of
our ordering.

commit 43ec16f1450f4936025a9bdf1a273affdb9732c1 upstream.
There is a crash in relay_file_read, as the var from
point to the end of last subbuf.
The oops looks something like:
pc : __arch_copy_to_user+0x180/0x310
lr : relay_file_read+0x20c/0x2c8
Call trace:
__arch_copy_to_user+0x180/0x310
full_proxy_read+0x68/0x98
vfs_read+0xb0/0x1d0
ksys_read+0x6c/0xf0
__arm64_sys_read+0x20/0x28
el0_svc_common.constprop.3+0x84/0x108
do_el0_svc+0x74/0x90
el0_svc+0x1c/0x28
el0_sync_handler+0x88/0xb0
el0_sync+0x148/0x180
We get the condition by analyzing the vmcore:
1). The last produced byte and last consumed byte
both at the end of the last subbuf
2). A softirq calls function(e.g __blk_add_trace)
to write relay buffer occurs when an program is calling
relay_file_read_avail().
relay_file_read
relay_file_read_avail
relay_file_read_consume(buf, 0, 0);
//interrupted by softirq who will write subbuf
....
return 1;
//read_start point to the end of the last subbuf
read_start = relay_file_read_start_pos
//avail is equal to subsize
avail = relay_file_read_subbuf_avail
//from points to an invalid memory address
from = buf->start + read_start
//system is crashed
copy_to_user(buffer, from, avail)

[ Upstream commit 71c4ca2d3b079d0ba4d9b3033641fea906cebfb6 ]
[why]
Newer ASICs such as DCN314 needs to allow for both self refresh and mem
clk switching rather than just self refresh only. Otherwise, we can see
some p-state hangs on ASICs that do support mem clk switching.
[how]
Added an allow_self_refresh_only flag for dcn30_internal_validate_bw
and created a validate_bw method for DCN314 with the allow_self_refresh_only
flag set to false (to support mem clk switching).

[ Upstream commit 1e994cc0956b8dabd1b1fef315bbd722733b8aa8 ]
[Why]
1. It could hit bandwidth limitdation under single dimm
memory when connecting 8K external monitor.
2. IsSupportedVidPn got validation failed with
2K240Hz eDP + 8K24Hz external monitor.
3. It's better to filter out such combination in
EnumVidPnCofuncModality
4. For short term, filter out in dc bandwidth validation.
[How]
Force 2K@240Hz+8K@24Hz timing validation false in dc.

[ Upstream commit 13b90cf900ab69dd5cab3cc5035bc7614037e64e ]
Currently, there are issues with enabling PSR-SU + DSC. This stems from
the fact that DSC imposes a slice height on transmitted video data and
we are not conforming to that slice height in PSR-SU regions. So, pass
slice_height into su_y_granularity to feed the DSC slice height into
PSR-SU code.

commit 2ed90cb0938a45b12eb947af062d12c7af0067b3 upstream.
Read mmu_invalidate_seq before dropping the mmap_lock so that KVM can
detect if the results of vma_lookup() (e.g. vma_shift) become stale
before it acquires kvm->mmu_lock. This fixes a theoretical bug where a
VMA could be changed by userspace after vma_lookup() and before KVM
reads the mmu_invalidate_seq, causing KVM to install page table entries
based on a (possibly) no-longer-valid vma_shift.
Re-order the MMU cache top-up to earlier in user_mem_abort() so that it
is not done after KVM has read mmu_invalidate_seq (i.e. so as to avoid
inducing spurious fault retries).
It's unlikely that any sane userspace currently modifies VMAs in such a
way as to trigger this race. And even with directed testing I was unable
to reproduce it. But a sufficiently motivated host userspace might be
able to exploit this race.
Note KVM/ARM had the same bug and was fixed in a separate, near
identical patch (see Link).

commit eb307d09fe15844fdaebeb8cc8c9b9e925430aa5 upstream.
racy issue is triggered the bug by racing between closing a connection
and rmmod. In ksmbd, rcu_barrier() is not called at module unload time,
so nothing prevents ksmbd from getting unloaded while it still has RCU
callbacks pending. It leads to trigger unintended execution of kernel
code locally and use to defeat protections such as Kernel Lockdown

If client send session setup request with unknown NTLMSSP message type,
session that does not included channel can be created. It will cause
session memleak. because ksmbd_sessions_deregister() does not destroy
session if channel is not included. This patch return error response if
client send the request unknown NTLMSSP message type.

commit 7b4323373d844954bb76e0e9f39c4e5fc785fa7b upstream.
Deadlock is triggered by sending multiple concurrent session setup
requests. It should be reused after releasing when getting ctx for crypto.
Multiple consecutive ctx uses cause deadlock while waiting for releasing
due to the limited number of ctx.

commit 3db66620ea90b0fd4134b31eabfec16d7b07d7e3 upstream.
Remove the acpi_backlight=video quirk for Lenovo ThinkPad W530.
This was intended to help users of the (unsupported) Nvidia binary driver,
but this has been reported to cause backlight control issues for users
who have the gfx configured in hybrid (dual-GPU) mode, so drop this.
The Nvidia binary driver should call acpi_video_register_backlight()
when necessary and this has been reported to Nvidia.
Until this is fixed Nvidia binary driver users can work around this by
passing "acpi_backlight=video" on the kernel commandline (with the latest
6.1.y or newer stable series, kernels < 6.1.y don't need this).

commit c770657bd2611b077ec1e7b1fe6aa92f249399bd upstream.
Using standard mode, rare false ACK responses were appearing with
i2cdetect tool. This was happening due to NACK interrupt triggering
ISR thread before register access interrupt was ready. Removing the
NACK interrupt's ability to trigger ISR thread lets register access
ready interrupt do this instead.

commit 4f94559f40ad06d627c0fdfc3319cec778a2845b upstream.
This file defines both read and write operations, yet it is being
created as read-only. This means that it can't be written to without the
CAP_DAC_OVERRIDE capability. Fix the permissions to allow root to write
to it without the need to override DAC perms.

commit ccc62b827775915a9b82db42a29813d04f92df7a upstream.
commit b9c6ff94e43a ("iommu/amd: Re-factor guest virtual APIC
(de-)activation code") while refactoring guest virtual APIC
activation/de-activation code, stored information for activate/de-activate
in "struct amd_ir_data". It used 32-bit integer data type for storing the
"Guest Virtual APIC Table Root Pointer" (ga_root_ptr), though the
"ga_root_ptr" is actually a 40-bit field in IRTE (Interrupt Remapping
Table Entry).
This causes interrupts from PCIe devices to not reach the guest in the case
of PCIe passthrough with SME (Secure Memory Encryption) enabled as _SME_
bit in the "ga_root_ptr" is lost before writing it to the IRTE.
Fix it by using 64-bit data type for storing the "ga_root_ptr". While at
that also change the data type of "ga_tag" to u32 in order to match
the IOMMU spec.

commit 41cad8284d5e6bf1d49d3c10a6b52ee1ae866a20 upstream.
sbi_probe_extension() is specified with "Returns 0 if the given SBI
extension ID (EID) is not available, or 1 if it is available unless
defined as any other non-zero value by the implementation."
Additionally, sbiret.value is a long. Fix the implementation to
ensure any nonzero long value is considered a success, rather
than only positive int values.

commit 7d01cb27f6aebc54efbe28d8961a973b8f795b13 upstream.
This reverts commit 122deabfe1428 (ubifs: dirty_cow_znode: Fix memleak
in error handling path).
After commit 122deabfe1428 applied, if insert_old_idx() failed, old
index neither exists in TNC nor in old-index tree. Which means that
old index node could be overwritten in layout_leb_in_gaps(), then
ubifs image will be corrupted in power-cut.

From: Zhihao Cheng <chengzhihao1@huawei.com>
commit b5fda08ef213352ac2df7447611eb4d383cce929 upstream.
Following process will cause a memleak for copied up znode:
dirty_cow_znode
zn = copy_znode(c, znode);
err = insert_old_idx(c, zbr->lnum, zbr->offs);
if (unlikely(err))
return ERR_PTR(err); // No one refers to zn.
Fetch a reproducer in [Link].
Function copy_znode() is split into 2 parts: resource allocation
and znode replacement, insert_old_idx() is split in similar way,
so resource cleanup could be done in error handling path without
corrupting metadata(mem & disk).
It's okay that old index inserting is put behind of add_idx_dirt(),
old index is used in layout_leb_in_gaps(), so the two processes do
not depend on each other.

commit 31a149d5c13c4cbcf97de3435817263a2d8c9d6e upstream.
The commit 2d78aee426d8 ("UBI: simplify LEB write and atomic LEB change code")
adds helper function, try_write_vid_and_data(), to simplify the code, but this
helper function has bug, it will return 0 (success) when ubi_io_write_vid_hdr()
or the ubi_io_write_data() return error number (-EIO, etc), because the return
value of ubi_wl_put_peb() will overwrite the original return value.
This issue will cause unexpected data loss issue, because the caller of this
function and UBIFS willn't know the data is lost.
Fixes: 2d78aee426d8 ("UBI: simplify LEB write and atomic LEB change code")

commit 1fb815b38bb31d6af9bd0540b8652a0d6fe6cfd3 upstream.
When opening a ubifs tmpfile on an encrypted directory, function
fscrypt_setup_filename allocates memory for the name that is to be
stored in the directory entry, but after the name has been copied to the
directory entry inode, the memory is not freed.
When running kmemleak on it we see that it is registered as a leak. The
report below is triggered by a simple program 'tmpfile' just opening a
tmpfile:
unreferenced object 0xffff88810178f380 (size 32):
comm "tmpfile", pid 509, jiffies 4294934744 (age 1524.742s)
backtrace:
__kmem_cache_alloc_node
__kmalloc
fscrypt_setup_filename
ubifs_tmpfile
vfs_tmpfile
path_openat
Free this memory after it has been copied to the inode.

commit 3a36d20e012903f45714df2731261fdefac900cb upstream.
If renaming a file in an encrypted directory, function
fscrypt_setup_filename allocates memory for a file name. This name is
never used, and before returning to the caller the memory for it is not
freed.
When running kmemleak on it we see that it is registered as a leak. The
report below is triggered by a simple program 'rename' that renames a
file in an encrypted directory:
unreferenced object 0xffff888101502840 (size 32):
comm "rename", pid 9404, jiffies 4302582475 (age 435.735s)
backtrace:
__kmem_cache_alloc_node
__kmalloc
fscrypt_setup_filename
do_rename
ubifs_rename
vfs_rename
do_renameat2
To fix this we can remove the call to fscrypt_setup_filename as it's not
needed.

From: Xiubo Li <xiubli@redhat.com>
commit aaf67de78807c59c35bafb5003d4fb457c764800 upstream.
When trimming the caps and just after the 'session->s_cap_lock' is
released in ceph_iterate_session_caps() the cap maybe removed by
another thread, and when using the stale cap memory in the callbacks
it will trigger use-after-free crash.
We need to check the existence of the cap just after the 'ci->i_ceph_lock'
being acquired. And do nothing if it's already removed.

commit a034c1370ded2ae6cbdc73a78241b3ed98c86d3d upstream.
This patch introduce a new internal flag per lkb value to handle
internal flags which are handled not on wire. The current lkb internal
flags stored as lkb->lkb_flags are split in upper and lower bits, the
lower bits are used to share internal flags over wire for other cluster
wide lkb copies on other nodes.
In commit 61bed0baa4db ("fs: dlm: use a non-static queue for callbacks")
we introduced a new internal flag for pending callbacks for the dlm
callback queue. This flag is protected by the lkb->lkb_cb_lock lock.
This patch overlooked that on dlm receive path and the mentioned upper
and lower bits, that dlm will read the flags, mask it and write it
back. As example receive_flags() in fs/dlm/lock.c. This flag
manipulation is not done atomically and is not protected by
lkb->lkb_cb_lock. This has unknown side effects of the current callback
handling.
In future we should move to set/clear/test bit functionality and avoid
read, mask and writing back flag values. In later patches we will move
the upper parts to the new introduced internal lkb flags which are not
shared between other cluster nodes to the new non shared internal flag
field to avoid similar issues.

commit aa88019851a85df80cb77f143758b13aee09e3d9 upstream.
In commit fe08cc504448 we reworked the valid superblock version
checks. If it is a V5 filesystem, it is always valid, then we
checked if the version was less than V4 (reject) and then checked
feature fields in the V4 flags to determine if it was valid.
What we missed was that if the version is not V4 at this point,
we shoudl reject the fs. i.e. the check current treats V6+
filesystems as if it was a v4 filesystem. Fix this.

commit 7701c8bef4f14bd9f7940c6ed0e6a73584115a96 upstream.
Decoders committed with 0-size lead to later crashes on shutdown as
__cxl_dpa_release() assumes a 'struct resource' has been established in
the in 'cxlds->dpa_res'. Just fail the driver load in this instance
since there are deeper problems with the enumeration or the setup when
this happens.

commit d469d9448a0f1a33c175d3280b1542fa0158ad7a upstream.
If we detect a system error via intvec, we only process the syserr if the
current ee is different than the last observed ee. The reason for this
check is to prevent bhie from running multiple times, but with the single
queue handling syserr, that is not possible.
The check can cause an issue with device recovery. If PBL loads a bad SBL
via BHI, but that SBL hangs before notifying the host of an ee change,
then issuing soc_reset to crash the device and retry (after supplying a
fixed SBL) will not recover the device as the host will observe a PBL->PBL
transition and not process the syserr. The device will be stuck until
either the driver is reloaded, or the host is rebooted. Instead, remove
the check so that we can attempt to recover the device.

commit 1d1493bdc25f498468a606a4ece947d155cfa3a9 upstream.
If firmware loading fails, the controller's pm_state is updated to
MHI_PM_FW_DL_ERR unconditionally. This can corrupt the pm_state as the
update is not done under the proper lock, and also does not validate
the state transition. The firmware loading can fail due to a detected
syserr, but if MHI_PM_FW_DL_ERR is unconditionally set as the pm_state,
the handling of the syserr can break when it attempts to transition from
syserr detect, to syserr process.
By grabbing the lock, we ensure we don't race with some other pm_state
update. By using mhi_try_set_pm_state(), we check that the transition
to MHI_PM_FW_DL_ERR is valid via the state machine logic. If it is not
valid, then some other transition is occurring like syserr processing, and
we assume that will resolve the firmware loading error.

commit 59257015ac8813d2430988aa01c2f4609a60e8e7 upstream.
The RX macro codec comes on some platforms in two variants - ADSP
and ADSP bypassed - thus the clock-names varies from 3 to 5. The clocks
must vary as well:
sc7280-idp.dtb: codec@3200000: clocks: [[202, 8], [202, 7], [203]] is too short

[ Upstream commit f9a301c3317daa921375da0aec82462ddf019928 ]
Fix bug in debugfs logs that causes an incorrect order of lines in the
debugfs log.
Currently, the test counts lines that show the number of tests passed,
failed, and skipped, as well as any suite diagnostic lines,
appear prior to the individual results, which is a bug.
Ensure the order of printing for the debugfs log is correct. Additionally,
add a KTAP header to so the debugfs logs can be valid KTAP.
This is an example of a log prior to these fixes:
KTAP version 1
# Subtest: kunit_status
1..2
# kunit_status: pass:2 fail:0 skip:0 total:2
# Totals: pass:2 fail:0 skip:0 total:2
ok 1 kunit_status_set_failure_test
ok 2 kunit_status_mark_skipped_test
ok 1 kunit_status
Note the two lines with stats are out of order. This is the same debugfs
log after the fixes (in combination with the third patch to remove the
extra line):
KTAP version 1
1..1
KTAP version 1
# Subtest: kunit_status
1..2
ok 1 kunit_status_set_failure_test
ok 2 kunit_status_mark_skipped_test
# kunit_status: pass:2 fail:0 skip:0 total:2
# Totals: pass:2 fail:0 skip:0 total:2
ok 1 kunit_status

resctrl_val() function is called only by MBM, MBA, and CMT tests which
means the else branch is never used.
Both test branches call param->setup().
Remove the unused else branch and place the ->setup() call outside of

resctrl_val() assumes ->setup() always returns either 0 to continue
tests or < 0 in case of the normal termination of tests after x runs.
The latter overlaps with normal error returns.
Define END_OF_TESTS (=1) to differentiate the normal termination of
tests and return errors as negative values. Alter callers of ->setup()
to handle errors properly.

Make the flask.h target depend on the genheaders binary instead of

genheaders are changed.
Notably this fixes flask.h not being rebuilt when
initial_sid_to_string.h is modified.

If in tpm_tis_probe_irq_single() an error occurs after the original
interrupt vector has been read, restore the interrupts before the error is
returned.
Since the caller does not check the error value, return -1 in any case that
the TPM_CHIP_FLAG_IRQ flag is not set. Since the return value of function
tpm_tis_gen_interrupt() is not longer used, make it a void function.

Both functions tpm_tis_probe_irq_single() and tpm_tis_probe_irq() may setup
the interrupts and then return with an error. This case is indicated by a
missing TPM_CHIP_FLAG_IRQ flag in chip->flags.
Currently the interrupt setup is only undone if tpm_tis_probe_irq_single()
fails. Undo the setup also if tpm_tis_probe_irq() fails.

In tpm_tis_probe_single_irq() interrupt registers TPM_INT_VECTOR,
TPM_INT_STATUS and TPM_INT_ENABLE are modified to setup the interrupts.
Currently these modifications are done without holding a locality thus they
have no effect. Fix this by claiming the (default) locality before the
registers are written.
Since now tpm_tis_gen_interrupt() is called with the locality already
claimed remove locality request and release from this function.

[ Upstream commit 7a2f55d0be296c4e81fd782f3d6c43ed4ec7e265 ]
Implement a usage counter for the (default) locality used by the TPM TIS
driver:
Request the locality from the TPM if it has not been claimed yet, otherwise
only increment the counter. Also release the locality if the counter is 0
otherwise only decrement the counter. Since in case of SPI the register
accesses are locked by means of the SPI bus mutex use a sleepable lock
(i.e. also a mutex) to ensure thread-safety of the counter which may be
accessed by both a userspace thread and the interrupt handler.
By doing this refactor the names of the amended functions to use a more
appropriate prefix.

In tpm_tis_resume() make sure that the locality has been claimed when
tpm_tis_reenable_interrupts() is called. Otherwise the writings to the
register might not have any effect.

[ Upstream commit 1b3567a1969b26f709d82a874498c0754ea841c3 ]
Given on-disk i_xattr_icount is 16 bits and xattr_isize is calculated
from i_xattr_icount multiplying 4, xattr_isize has a theoretical maximum
of 256K (64K * 4).
Thus declare xattr_isize as unsigned int to avoid the potential overflow.

[ Upstream commit a8e47884f1906cd7440fafa056adc8817568e73e ]
Currently we schedule a call to output_poll_execute from
drm_kms_helper_poll_enable for 10s in future. Later we try to replace
that in drm_helper_probe_single_connector_modes with a 0s schedule with
delayed_event set.
But as there is already a job in the queue this fails, and the immediate
job we wanted with delayed_event set doesn't occur until 10s later.
And that call acts as if connector state has changed, reprobing modes.
This has a side effect of waking up a display that has been blanked.
Make sure we cancel the old job before submitting the immediate one.

Commit 3840c5bcc245 ("drm/amdgpu: disentangle runtime pm and
vga_switcheroo") made amdgpu only register a vga_switcheroo client for
GPU's with PX, however AMD GPUs in dual gpu Apple Macbooks do need to
register, but don't have PX. Instead of AMD's PX, they use apple-gmux.
Use apple_gmux_detect() to identify these gpus, and
pci_is_thunderbolt_attached() to ensure eGPUs connected to Dual GPU
Macbooks don't register with vga_switcheroo.

[ Upstream commit 5f1732a8683c1da8faaa90d6ffc3bd6d33013a58 ]
When the k3 ring accelerator driver has been modified to add module build
support, try_module_get() and module_put() have been added to update the
module refcnt. One code path has not been updated and it has introduced
an issue where the refcnt is decremented by module_put() in
k3_ringacc_ring_free() without being incremented previously.
Adding try_module_get() to k3_dmaring_request_dual_ring() ensures the
refcnt is kept up to date.

[ Upstream commit 8f3c307b580a4a6425896007325bddefc36e8d91 ]
wkup_m3_ipc_get() takes refcount, which should be freed by
wkup_m3_ipc_put(). Add missing refcount release in the error paths.

[ Upstream commit fb76b0fae3ca880363214e1dcd6513ab8bd529e7 ]
According to the R-Car Series, 3rd Generation Hardware User’s Manual
Rev. 2.30, the System CPU cores on R-Car E3 do not have their own power
supply, but use the common internal power supply (typical 1.03V).
Hence remove the "opp-microvolt" properties from the Operating
Performance Points table. They are optional, and unused, when none of
the CPU nodes is tied to a regulator using the "cpu-supply" property.

[ Upstream commit 36b617f7e4ae663fcadd202ea061ca695ca75539 ]
The MediaTek DisplayPort interface bridge driver starts its interrupts
as soon as its probed. However when the interrupts trigger the bridge
might not have been attached to a DRM device. As drm_helper_hpd_irq_event()
does not check whether the passed in drm_device is valid or not, a NULL
pointer passed in results in a kernel NULL pointer dereference in it.
Check whether the bridge is attached and only trigger an HPD event if
it is.

The current DRAM row address mapping arrays skx_{open,close}_row[]
only support ranks with sizes up to 16G. Decoding a rank address
to a DRAM row address for a 32G rank by using either one of the
above arrays by the skx_edac driver, will result in an overflow on
the array.
For a 32G rank, the most significant DRAM row address bit (the
bit17) is mapped from the bit34 of the rank address. Add this new
mapping item to both arrays to fix the overflow issue.

From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit 691c1fcda5351ed98a44610b7dccc0e3ee920020 ]
This is very close to a straight revert of commit 218320fec294
("regulator: core: Fix off-on-delay-us for always-on/boot-on
regulators"). We've identified that patch as causing a boot speed
regression on sc7180-trogdor boards. While boot speed certainly isn't
more important than making sure that power sequencing is correct,
looking closely at the original change it doesn't seem to have been
fully justified. It mentions "cycling issues" without describing
exactly what the issues were. That means it's possible that the
cycling issues were really a problem that should be fixed in a
different way.
Let's take a careful look at how we should handle regulators that have
an off-on-delay and that are boot-on or always-on. Linux currently
doesn't have any way to identify whether a GPIO regulator was already
on when the kernel booted. That means that when the kernel boots we
probe a regulator, see that it wants boot-on / always-on we, and then
turn the regulator on. We could be in one of two cases when we do
this:
a) The regulator might have been left on by the bootloader and we're
ensuring that it stays on.
b) The regulator might have been left off by the bootloader and we're
just now turning it on.
For case a) we definitely don't need any sort of delay. For case b) we
_might_ need some delay in case the bootloader turned the regulator
off _right_ before booting the kernel. To get the proper delay for
case b) then we can just assume a `last_off` of 0, which is what it
gets initialized to by default.
As per above, we can't tell whether we're in case a) or case b) so
we'll assume the longer delay (case b). This basically puts the code
to how it was before commit 218320fec294 ("regulator: core: Fix
off-on-delay-us for always-on/boot-on regulators"). However, we add
one important change: we make sure that the delay is actually honored
if `last_off` is 0. Though the original "cycling issues" cited were
vague, I'm hopeful that this important extra change will be enough to
fix the issues that the initial commit mentioned.
With this fix, I've confined that on a sc7180-trogdor board the delay
at boot goes down from 500 ms to ~250 ms. That's not as good as the 0
ms that we had prior to commit 218320fec294 ("regulator: core: Fix
off-on-delay-us for always-on/boot-on regulators"), but it's probably
safer because we don't know if the bootloader turned the regulator off
right before booting.
One note is that it's possible that we could be in a state that's not
a) or b) if there are other issues in the kernel. The only one I can
think of is related to pinctrl. If the pinctrl driver being used on a
board isn't careful about avoiding glitches when setting up a pin then
it's possible that setting up a pin could cause the regulator to "turn
off" briefly immediately before the regulator probes. If this is
indeed causing problems then the pinctrl driver should be fixed,
perhaps in a similar way to what was done in commit d21f4b7ffc22
("pinctrl: qcom: Avoid glitching lines when we first mux to output")

All revisions of AM62A7-SK board have 4GB LPDDR4 Micron
MT53E2G32D4DE-046 AUT:B memory. Commit 38c4a08c820c ("arm64: dts: ti:
Add support for AM62A7-SK") enabled just 2GB due to a schematics error
in early revision of the board. Fix it by enabling full 4GB available on

According to latest errata of J721e [1], (i2024) 'MMCSD: Peripherals
Do Not Support HS400' which applies to MMCSD0 subsystem. Speed modes
supported has been already updated but missed dropping 'ti,strobe-sel'
property which is only required by HS400 speed mode.
Thus, drop 'ti,strobe-sel' property from kernel dtsi for J721e SoC.

[ Upstream commit 44750f153699b6e4f851a399287e5c8df208d696 ]
While stressing EAS on my dragonboard RB3, I have noticed that LITTLE cores
where never selected as the most energy efficient CPU whatever the
utilization level of waking task.
energy model framework uses its cost field to estimate the energy with
the formula:
nrg = cost of the selected OPP * utilization / CPU's max capacity
which ends up selecting the CPU with lowest cost / max capacity ration
as long as the utilization fits in the OPP's capacity.
If we compare the cost of a little OPP with similar capacity of a big OPP
like :
OPP(kHz) OPP capacity cost max capacity cost/max capacity
LITTLE 1766400 407 351114 407 863
big 1056000 408 520267 1024 508
This can be interpreted as the LITTLE core consumes 70% more than big core
for the same compute capacity.
According to [1], LITTLE consumes 10% less than big core for Coremark
benchmark at those OPPs. If we consider that everything else stays
unchanged, the dynamic-power-coefficient of LITTLE core should be
only 53% of the current value: 290 * 53% = 154
Set the dynamic-power-coefficient of CPU0-3 to 154 to fix the energy model.

[ Upstream commit 6db9ed9a128cbae1423d043f3debd8bfa77783fd ]
Some lines were broken very aggresively, presumably to fit under 80 chars
and some places could have used a newline, particularly between subsequent
nodes. Address all that and remove redundant comments near PCIe ranges
while at it so as not to exceed 100 chars needlessly.

[ Upstream commit 75a6e1fdb351189f55097741e8460ca3f9b2883f ]
For 64KiB of the I/O region, the I/O ports of the legacy PCI devices are
located in the range of 0x0 to 0x10000. Hence, fix the bogus PCI address
(0x20200000) specified in the ranges property for I/O region.
While at it, let's use the missing 0x prefix for the addresses.

For 1MiB of the I/O region, the I/O ports of the legacy PCI devices are

In order for consumers of RPMCC XO clock to probe successfully
their parent needs to be feed with reference clock to obtain proper rate,
add fixed xo-board clock and supply it to rpmcc to make consumers happy.
Frequency setting is left per board basis just like on other recent trees.

[ Upstream commit 3b76b736cd9933ff88764ffec01cbd859c1475e7 ]
Unit address of PCIe EP node should be 0x1c00000 as it has to match the
first address specified in the reg property.
This also requires sorting the node in the ascending order.

[ Upstream commit 4c1cdec319b9aadb65737c3eb1f5cb74bd6aa156 ]
Thee maximum number of MCA banks is 64 (MAX_NR_BANKS), see
a0bc32b3cacf ("x86/mce: Increase maximum number of banks to 64").
However, the bank_map which contains a bitfield of which banks to
initialize is of type unsigned int and that overflows when those bit
numbers are >= 32, leading to UBSAN complaining correctly:
UBSAN: shift-out-of-bounds in arch/x86/kernel/cpu/mce/amd.c:1365:38
shift exponent 32 is too large for 32-bit type 'int'
Change the bank_map to a u64 and use the proper BIT_ULL() macro when
modifying bits in there.
[ bp: Rewrite commit message. ]

[ Upstream commit eed9496a0501357aa326ddd6b71408189ed872eb ]
The buf[4] value comes from the user via ts_play(). It is a value in
the u8 range. The final length we pass to av7110_ipack_instant_repack()
is "len - (buf[4] + 1) - 4" so add a check to ensure that the length is
not negative. It's not clear that passing a negative len value does
anything bad necessarily, but it's not best practice.
With the new bounds checking the "if (!len)" condition is no longer
possible or required so remove that.

From: Adam Ford <aford173@gmail.com>
[ Upstream commit ee0285e13455fdbce5de315bdbe91b5f198a2a06 ]
When dynamically switching lanes was removed, the intent of the code
was to check to make sure that higher speed items used 4 lanes, but
it had the unintended consequence of removing the slower speeds for
4-lane users.
This attempts to remedy this by doing a check to see that the
max frequency doesn't exceed the chip limit, and a second
check to make sure that the max bit-rate doesn't exceed the
number of lanes * max bit rate / lane.

[ Upstream commit 010c8bbad2cb8c33c47963e29f051f1e917e45a5 ]
Downstream driver appears to not support preemption on A510 target,
trying to use one make device slow and fill log with rings related errors.
Set num_rings to 1 to disable preemption.

[ Upstream commit 073828e954459b883f23e53999d31e4c55ab9654 ]
In ACPI systems, the OS can direct power management, as opposed to the
firmware. This OS-directed Power Management is called OSPM. Part of
telling the firmware that the OS going to direct power management is
making ACPI "_PDC" (Processor Driver Capabilities) calls. These _PDC
methods must be evaluated for every processor object. If these _PDC
calls are not completed for every processor it can lead to
inconsistency and later failures in things like the CPU frequency
driver.
In a Xen system, the dom0 kernel is responsible for system-wide power
management. The dom0 kernel is in charge of OSPM. However, the
number of CPUs available to dom0 can be different than the number of
CPUs physically present on the system.
This leads to a problem: the dom0 kernel needs to evaluate _PDC for
all the processors, but it can't always see them.
In dom0 kernels, ignore the existing ACPI method for determining if a
processor is physically present because it might not be accurate.
Instead, ask the hypervisor for this information.
Fix this by introducing a custom function to use when running as Xen
dom0 in order to check whether a processor object matches a CPU that's
online. Such checking is done using the existing information fetched
by the Xen pCPU subsystem, extending it to also store the ACPI ID.
This ensures that _PDC method gets evaluated for all physically online
CPUs, regardless of the number of CPUs made available to dom0.

If spec_reg is equal to 'SDHCI_PRESENT_STATE', esdhc_readl_fixup()
fixes up register value and returns it immediately. As a result, the
further block
(spec_reg == SDHCI_PRESENT_STATE)
&&(esdhc->quirk_ignore_data_inhibit == true),
is never executed.

From: H. Nikolaus Schaller <hns@goldelico.com>
[ Upstream commit a622310f7f0185da02e42cdb06475f533efaae60 ]
OMAP processors support 32 channels but there is no check or
inspect this except booting a device and looking at dmesg reports
of not available channels.
Recently some more subsystems with DMA (aes1+2) were added filling
the list of dma channels beyond the limit of 32 (even if other
parameters indicate 96 or 128 channels). This leads to random
subsystem failures i(e.g. mcbsp for audio) after boot or boot
messages that DMA can not be initialized.
Another symptom is that
/sys/kernel/debug/dmaengine/summary
has 32 entries and does not show all required channels.
Fix by disabling unused (on the GTA04 hardware) mcspi1...4.
Each SPI channel allocates 4 DMA channels rapidly filling
the available ones.
Disabling unused SPI modules on the OMAP3 SoC may also save
some energy (has not been checked).

[ Upstream commit b2ccba9e8cdc6fb3985cc227844e7c6af309ffb1 ]
Two distinct pools of xfer descriptors are allocated at initialization
time: one (Tx) used to provide xfers to track commands and their replies
(or delayed replies) and another (Rx) to pick xfers from to be used for
processing notifications.
Such pools, though, are allocated globally to be used by the whole SCMI
instance, they are not allocated per-channel and as such the allocation of
notifications xfers cannot be simply skipped if no Rx channel was found for
the base protocol common channel, because there could be defined more
optional per-protocol dedicated channels that instead support Rx channels.
Change the conditional check to skip allocation for the notification pool
only if no Rx channel has been detected on any per-channel protocol at all.

The PCIe ports are unused (without devices) so disable them instead of
removing them.

[ Upstream commit d51e106240bc755cbe59634b70d567c192b045b2 ]
Any kind of failure in mtk_cpu_dvfs_info_init() will lead to calling
regulator_put() or clk_put() and the KP will occur since the regulator/clk
handlers are used after released in mtk_cpu_dvfs_info_release().
To prevent the usage after regulator_put()/clk_put(), the regulator/clk
handlers are addressed in a way of "Free the Last Thing Style".

[ Upstream commit d3296bb4cafd4bad4a5cf2eeab9d19cc94f9e30e ]
Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
which is greater than the value of MT2701 1150 mV, we fix it by adding
the corresponding platform data and specify proc/sram_max_volt to
support MT8516.

[ Upstream commit 0883426fd07e39355362e3f2eb9aee1a154dcaf6 ]
During the addition of SRAM voltage tracking for CCI scaling, this
driver got some voltage limits set for the vtrack algorithm: these
were moved to platform data first, then enforced in a later commit
6a17b3876bc8 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
using these as max values for the regulator_set_voltage() calls.
In this case, the vsram/vproc constraints for MT7622 and MT7623
were supposed to be the same as MT2701 (and a number of other SoCs),
but that turned out to be a mistake because the aforementioned two
SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V.
Fix that by adding new platform data for MT7622/7623 declaring the
right {proc,sram}_max_volt parameter.

[ Upstream commit e2b47e585931a988c856fd4ba31e1296f749aee3 ]
The OSM/EPSS hardware controls the frequency of each CPU cluster based
on requests from the OS and various throttling events in the system.
While throttling is in effect the related dcvs interrupt will be kept
high. The purpose of the code handling this interrupt is to
continuously report the thermal pressure based on the throttled
frequency.
The reasoning for adding QoS control to this mechanism is not entirely
clear, but the introduction of commit 'c4c0efb06f17 ("cpufreq:
qcom-cpufreq-hw: Add cpufreq qos for LMh")' causes the
scaling_max_frequncy to be set to the throttled frequency. On the next
iteration of polling, the throttled frequency is above or equal to the
newly requested frequency, so the polling is stopped.
With cpufreq limiting the max frequency, the hardware no longer report a
throttling state and no further updates to thermal pressure or qos
state are made.
The result of this is that scaling_max_frequency can only go down, and
the system becomes slower and slower every time a thermal throttling
event is reported by the hardware.
Even if the logic could be improved, there is no reason for software to
limit the max freqency in response to the hardware limiting the max
frequency. At best software will follow the reported hardware state, but
typically it will cause slower backoff of the throttling.
This reverts commit c4c0efb06f17fa4a37ad99e7752b18a5405c76dc.

The MT8192 SoC specifies a maximum voltage for the GPU's digital supply
of 0.88V and the GPU OPPs are declaring a maximum voltage of 0.80V.
In order to keep the GPU voltage in the safe range, change the maximum
voltage for mt6315@7's vbuck1 to 0.80V as sending, for any mistake,
1.193V would be catastrophic.

[ Upstream commit 47d26684185d09e083669bbbd0c465ab3493a51f ]
When setting up DMA for a PCI device, we need to initialize its
iommu_fwspec with all possible alias RIDs (such as PCI bridges). To do
this we use pci_for_each_dma_alias() which calls
viot_pci_dev_iommu_init(). This function incorrectly initializes the
fwspec of the bridge instead of the device being configured. Fix it by
passing the original device as context to pci_for_each_dma_alias().

[ Upstream commit b5984a9844fc45cd301a28fb56f3de95f7e20f3c ]
The system controller on PolarFire SoC has no interrupt to signify that
the TX has been completed. The interrupt instead signals that a service
requested by the mailbox client has succeeded. If a service fails, there
will be no interrupt delivered.
Switch to polling the busy register to determine whether transmission
has completed.
Fixes: 83d7b1560810 ("mbox: add polarfire soc system controller mailbox")

return an error code, so the module can be loaded successfully,
when it's unloading, the host1x_memory_context_list_free() is
called in host1x_remove(), it will cause double free. Set the

[ Upstream commit 55879dad0f3ae8468444b42f785ad79eac05fe5b ]
The device names allocated by dev_set_name() need be freed
before module unloading, but they can not be freed because
the kobject's refcount which was set in device_initialize()
has not be decreased to 0.
As comment of device_add() says, if it fails, use only
put_device() drop the refcount, then the name will be
freed in kobejct_cleanup().
device_del() and put_device() can be replaced with
device_unregister(), so call it to unregister the added
successfully devices, and just call put_device() to the
not added device.
Add a release() function to device to avoid null release()
function WARNING in device_release(), it's empty, because
the context devices are freed together in
host1x_memory_context_list_free().

[ Upstream commit 97b4fdc6b82d6d5cfb92a9b164540278720fb700 ]
This reverts commit 46546f28825cf3a5ef6873b9cf947cd85c8a7258 because it
mistakenly took PMIC pinctrl/GPIO as TLMM. The TLMM pinctrl uses "gpio"
function, but PMIC uses "normal", so original code was correct:
msm8998-oneplus-cheeseburger.dtb: pmic@2: gpio@c000:button-backlight-state: 'oneOf' conditional failed, one must be fixed:
'gpio' is not one of ['normal', 'paired', 'func1', 'func2', 'dtest1', 'dtest2', 'dtest3', 'dtest4', 'func3', 'func4']

[ Upstream commit 379989e7cbdc7aa7496a00ee286ec146c7599cf0 ]
When hitting an error, the error path forgot to unmap dma mappings and
could call set_pages_wb() on already uncached pages.
Fix this by introducing a common ttm_pool_free_range() function that
does the right thing.
v2:
- Simplify that common function (Christian König)
v3:
- Rename that common function to ttm_pool_free_range() (Christian König)

[ Upstream commit b83a1772be854f87602de14726737d3e5b06e1f4 ]
When a codepath locks a rdev using ww_mutex_lock_slow() directly then
that codepath is responsible for incrementing the "ref_cnt" and also
setting the "mutex_owner" to "current".
The regulator core consistently got that right for "ref_cnt" but
didn't always get it right for "mutex_owner". Let's fix this.
It's unlikely that this truly matters because the "mutex_owner" is
only needed if we're going to do subsequent locking of the same
rdev. However, even though it's not truly needed it seems less
surprising if we consistently set "mutex_owner" properly.

[ Upstream commit cba6cfdc7c3f1516f0d08ddfb24e689af0932573 ]
An automated bot told me that there was a potential lockdep problem
with regulators. This was on the chromeos-5.15 kernel, but I see
nothing that would be different downstream compared to upstream. The
bot said:

The problem was first reported soon after we made many of the
regulators probe asynchronously, though nothing I've seen implies that
the problems couldn't have also happened even without that.
I haven't personally been able to reproduce the lockdep issue, but the
issue does look somewhat legitimate. Specifically, it looks like in
regulator_resolve_supply() we are holding a "rdev" lock while calling
set_supply() -> create_regulator() which grabs the lock of a
_different_ "rdev" (the one for our supply). This is not necessarily
safe from a lockdep perspective since there is no documented ordering
between these two locks.
In reality, we should always be locking a regulator before the
supplying regulator, so I don't expect there to be any real deadlocks
in practice. However, the regulator framework in general doesn't
express this to lockdep.
Let's fix the issue by simply grabbing the two locks involved in the
same way we grab multiple locks elsewhere in the regulator framework:
using the "wound/wait" mechanisms.

[ Upstream commit f96fb2df3eb31ede1b34b0521560967310267750 ]
The detection of atomic update failure in reserve_eilvt_offset() is
not correct. The value returned by atomic_cmpxchg() should be compared
to the old value from the location to be updated.
If these two are the same, then atomic update succeeded and
"eilvt_offsets[offset]" location is updated to "new" in an atomic way.
Otherwise, the atomic update failed and it should be retried with the
value from "eilvt_offsets[offset]" - exactly what atomic_try_cmpxchg()
does in a correct and more optimal way.

[ Upstream commit c85c8a992794dfcd7cea7a41871710c27c5592a6 ]
This fixes memory overlap error:
[ 0.000000] reserved@6300000 (0x0000000006300000--0x0000000007000000) overlaps with smem_region@6a00000 (0x0000000006a00000--0x0000000006c00000)
smem_region is the same as in downstream (qcom,smem) [1], therefore
split reserved memory into two sections on either side of smem_region.
Not adding labels as it's not expected to be used.

[ Upstream commit d84f8f2687bdc67f20262e822b206419bcfd0038 ]
There are 4 qspi data pins: data0, data1, data2, and data3. Currently
we have a shared pin state for data0 and data1 (2 lane config) and a
pin state for data2 and data3 (you'd enable both this and the 2 lane
state for 4 lanes). The second state is obviously misnamed. Fix it.

1. Move removing buffer after sw setting and before hw setting
in enc&dec worker to prevents the operation of removing
the buffer twice if the sw setting fails.
2. Remove the redundant operation of queue work in the
jpegenc irq handler because the jpegenc worker has called
v4l2_m2m_job_finish to do it.

[ Upstream commit e25528e1dbe52784ac250071653104a8adc848e2 ]
After commit b018be06f3c7 ("media: mediatek: vcodec: Read max resolution
from dec_capability"), the stateful video decoder driver never really
sets its output frame size to 4K.
Parse the decoder capability reported by the firmware, and update the
output frame size in mtk_init_vdec_params to enable 4K frame size when
available.

[ Upstream commit 6d020d81b91af80a977061e82de25cafa4456af5 ]
Given that only the MM21 capture format is supported by userspace tools
(like gstreamer and libyuv), make it the default capture format.
This allows us to force the MM21 format even when a MM21 and MT21C capable
firmware is available (which is needed while dynamic format switching isn't
implemented in the driver), without causing the following regressions on
v4l2-compliance:
fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT

[ Upstream commit 68c7df527657a9e962da7b5b9c0308557357d8dc ]
While the decoder can produce frames in both MM21 and MT21C formats, only
MM21 is currently supported by userspace tools (like gstreamer and libyuv).
In order to ensure userspace keeps working after the SCP firmware is
updated to support both MM21 and MT21C formats, force the MM21 format for
the capture queue.
This is meant as a stopgap solution while dynamic format switching between
MM21 and MT21C isn't implemented in the driver.

[ Upstream commit 50d0a7aea4809cef87979d4669911276aa23b71f ]
In cedrus_probe, dev->watchdog_work is bound with cedrus_watchdog function.
In cedrus_device_run, it will started by schedule_delayed_work. If there is
an unfinished work in cedrus_remove, there may be a race condition and
trigger UAF bug.

[ Upstream commit 3228cec23b8b29215e18090c6ba635840190993d ]
In rkvdec_probe, rkvdec->watchdog_work is bound with
rkvdec_watchdog_func. Then rkvdec_vp9_run may
be called to start the work.
If we remove the module which will call rkvdec_remove
to make cleanup, there may be a unfinished work.
The possible sequence is as follows, which will
cause a typical UAF bug.
Fix it by canceling the work before cleanup in rkvdec_remove.

[ Upstream commit aec8298c093f052fc8a86f9411b69b23953b0edb ]
The current SMN index used for the driver probe seems to be meant
for the BIOS pair and there are potential concurrency problems that can
occur with an inopportune SMI.
It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_2, which is
what amd_nb.c provides and this function has protections to ensure that
only one caller can use it at a time.

The version check requirement for idle mask support actually only
applies to RN/CZN/BRC platforms.
So far no issues have happened because the PMFW version string is
bigger on other supported systems. This can be reset for any new platform
so move the check to only RN/CZN/BRC case.

[ Upstream commit 310e782a99c7f16fb533a45d8f9c16defefa5aab ]
The current SMN index used for the driver probe seems to be meant
for the BIOS pair and there are potential concurrency problems that can
occur with an inopportune SMI.
It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_2, which is
what amd_nb.c provides and this function has protections to ensure that
only one caller can use it at a time.

[ Upstream commit 5abda7a16698d4d1f47af1168d8fa2c640116b4a ]
In dm1105_probe, it called dm1105_ir_init and bound
&dm1105->ir.work with dm1105_emit_key.
When it handles IRQ request with dm1105_irq,
it may call schedule_work to start the work.
When we call dm1105_remove to remove the driver, there
may be a sequence as follows:
Fix it by finishing the work before cleanup in dm1105_remove

[ Upstream commit 30cf57da176cca80f11df0d9b7f71581fe601389 ]
In saa7134_initdev, it will call saa7134_hwinit1. There are three
function invoking here: saa7134_video_init1, saa7134_ts_init1
and saa7134_vbi_init1.
All of them will init a timer with same function. Take
saa7134_video_init1 as an example. It'll bound &dev->video_q.timeout
with saa7134_buffer_timeout.
In buffer_activate, the timer funtcion is started.
If we remove the module or device which will call saa7134_finidev
to make cleanup, there may be a unfinished work. The
possible sequence is as follows, which will cause a
typical UAF bug.
Fix it by canceling the timer works accordingly before cleanup in
saa7134_finidev.

[ Upstream commit 52d8caca3d533cc499f1255be25576ffd936ec95 ]
The vsp1 driver uses the vb2_is_streaming() function in its .buf_queue()
handler to check if the .start_streaming() operation has been called,
and decide whether to just add the buffer to an internal queue, or also
trigger a hardware run. vb2_is_streaming() relies on the vb2_queue
structure's streaming field, which used to be set only after calling the
.start_streaming() operation.
Commit a10b21532574 ("media: vb2: add (un)prepare_streaming queue ops")
changed this, setting the .streaming field in vb2_core_streamon() before
enqueuing buffers to the driver and calling .start_streaming(). This
broke the vsp1 driver which now believes that .start_streaming() has
been called when it hasn't, leading to a crash:

A different regression report sent to the linux-media mailing list ([1])
was answered with a claim that the vb2_is_streaming() function has never
been meant for this purpose. The document of the function, as well as of
the struct vb2_queue streaming field, is sparse, so this claim may be
hard to verify.
The information needed by the vsp1 driver to decide how to process
queued buffers is also available from the vb2_start_streaming_called()
function. Use it instead of vb2_is_streaming() to fix the problem.

[ Upstream commit 5c5a7680e67ba6fbbb5f4d79fa41485450c1985c ]
struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
So this is an source for errors typically yielding resource leaks in the
error path.
As there are too many platform drivers to neatly convert them all to
return void in a single go, do it in several steps after this patch:
a) Convert all drivers to implement .remove_new() returning void instead
of .remove() returning int;
b) Change struct platform_driver::remove() to return void and so make
it identical to .remove_new();
c) Change all drivers back to .remove() now with the better prototype;
d) drop struct platform_driver::remove_new().
While this touches all drivers eventually twice, steps a) and c) can be
done one driver after another and so reduces coordination efforts
immensely and simplifies review.

[ Upstream commit 0e82d3715fd208de567b8e4307fbf91ae5e57db4 ]
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

[ Upstream commit 5276c9df9c2ab9a43b534bfb56bdb10899cd3a22 ]
When an async notifier is unregistered, the async sub-devices in the
notifier's done list will disappear with the notifier. However this is
currently also done to the sub-notifiers that remain registered. Their
sub-devices only need to be unbound while the async sub-devices themselves
need to be returned to the sub-notifier's waiting list. Do this now.

[ Upstream commit 9c592f8ab114875fdb3b2040f01818e53de44991 ]
The driver was intended from the start to be a wake-up source for the
system, however due to the absence of a suitable call to
device_set_wakeup_capable(), the device_may_wakeup() call used to decide
whether to enable the GPIO interrupt as a wake-up source would never
happen. Lookup the DT standard "wakeup-source" property and call
device_init_wakeup() to ensure the device is flagged as being wakeup
capable.

[ Upstream commit 50248ad9f190d527cbd578190ca769729518b703 ]
The decoder driver should clear the last_buffer_dequeued flag of the
capture queue upon receiving V4L2_DEC_CMD_START.
The last_buffer_dequeued flag is set upon receiving EOS (which always
happens upon receiving V4L2_DEC_CMD_STOP).
Without this patch, after issuing the V4L2_DEC_CMD_STOP and
V4L2_DEC_CMD_START, the vb2_dqbuf() function will always fail, even if
the buffers are completed by the hardware.

[ Upstream commit a9d45ec74c8e68aaafe90191928eddbf79f4644f ]
Commit 9593126dae3e ("media: venus: Add a handling of QC08C compressed
format") and commit cef92b14e653 ("media: venus: Add a handling of QC10C
compressed format") added support for the QC08C and QC10C compressed
formats respectively.
But these also caused a regression, because the new formats where added
at the beginning of the vdec_formats[] array and the vdec_inst_init()
function sets the default format output and capture using fixed indexes
of that array:
static void vdec_inst_init(struct venus_inst *inst)
{
...
inst->fmt_out = &vdec_formats[8];
inst->fmt_cap = &vdec_formats[0];
...
}
Since now V4L2_PIX_FMT_NV12 is not the first entry in the array anymore,
the default capture format is not set to that as it was done before.
Both commits changed the first index to keep inst->fmt_out default format
set to V4L2_PIX_FMT_H264, but did not update the latter to keep .fmt_out
default format set to V4L2_PIX_FMT_NV12.
Rather than updating the index to the current V4L2_PIX_FMT_NV12 position,
let's reorder the entries so that this format is the first entry again.
This would also make VIDIOC_ENUM_FMT report the V4L2_PIX_FMT_NV12 format
with an index 0 as it did before the QC08C and QC10C formats were added.

Smatch reports:
drivers/regulator/stm32-pwr.c:166 stm32_pwr_regulator_probe() warn:
'base' from of_iomap() not released on lines: 151,166.
In stm32_pwr_regulator_probe(), base is not released
when devm_kzalloc() fails to allocate memory or
devm_regulator_register() fails to register a new regulator device,
which may cause a leak.
To fix this issue, replace of_iomap() with
devm_platform_ioremap_resource(). devm_platform_ioremap_resource()
is a specialized function for platform devices.
It allows 'base' to be automatically released whether the probe
function succeeds or fails.
Besides, use IS_ERR(base) instead of !base
as the return value of devm_platform_ioremap_resource()
can either be a pointer to the remapped memory or
an ERR_PTR() encoded error code if the operation fails.

[ Upstream commit 5af507bef93c09a94fb8f058213b489178f4cbe5 ]
arch_dynirq_lower_bound() is invoked by the core interrupt code to
retrieve the lowest possible Linux interrupt number for dynamically
allocated interrupts like MSI.
The x86 implementation uses this to exclude the IO/APIC GSI space.
This works correctly as long as there is an IO/APIC registered, but
returns 0 if not. This has been observed in VMs where the BIOS does
not advertise an IO/APIC.
0 is an invalid interrupt number except for the legacy timer interrupt
on x86. The return value is unchecked in the core code, so it ends up
to allocate interrupt number 0 which is subsequently considered to be
invalid by the caller, e.g. the MSI allocation code.
The function has already a check for 0 in the case that an IO/APIC is
registered, as ioapic_dynirq_base is 0 in case of device tree setups.
Consolidate this and zero check for both ioapic_dynirq_base and gsi_top,
which is used in the case that no IO/APIC is registered.

[ Upstream commit af6c0bd59f4f3ad5daad2f7b777954b1954551d5 ]
Currently only the first attempt to single-step has any effect. After
that all further stepping remains "stuck" at the same program counter
value.
Refer to the ARM Architecture Reference Manual (ARM DDI 0487E.a) D2.12,
PSTATE.SS=1 should be set at each step before transferring the PE to the
'Active-not-pending' state. The problem here is PSTATE.SS=1 is not set
since the second single-step.
After the first single-step, the PE transferes to the 'Inactive' state,
with PSTATE.SS=0 and MDSCR.SS=1, thus PSTATE.SS won't be set to 1 due to
kernel_active_single_step()=true. Then the PE transferes to the
'Active-pending' state when ERET and returns to the debugger by step
exception.

[ Upstream commit 2ad91e44e6b0c7ef1ed151b3bb2242a2144e6085 ]
When the "extra device ports" configuration was first added, the
additional mxp_device_port_connect_info registers were added around the
existing mxp_mesh_port_connect_info registers. What I missed about
CMN-700 is that it shuffled them around to remove this discontinuity.
As such, tweak the definitions and factor out a helper for reading these
registers so we can deal with this discrepancy easily, which does at
least allow nicely tidying up the callsites. With this we can then also
do the nice thing and skip accesses completely rather than relying on
RES0 behaviour where we know the extra registers aren't defined.

[ Upstream commit 63a759694eed61025713b3e14dd827c8548daadc ]
Statically initialized objects are usually not initialized via the init()
function of the subsystem. They are special cased and the subsystem
provides a function to validate whether an object which is not yet tracked
by debugobjects is statically initialized. This means the object is started
to be tracked on first use, e.g. activation.
This works perfectly fine, unless there are two concurrent operations on
that object. Schspa decoded the problem:
T0 T1
debug_object_assert_init(addr)
lock_hash_bucket()
obj = lookup_object(addr);
if (!obj) {
unlock_hash_bucket();
- > preemption
lock_subsytem_object(addr);
activate_object(addr)
lock_hash_bucket();
obj = lookup_object(addr);
if (!obj) {
unlock_hash_bucket();
if (is_static_object(addr))
init_and_track(addr);
lock_hash_bucket();
obj = lookup_object(addr);
obj->state = ACTIVATED;
unlock_hash_bucket();
subsys function modifies content of addr,
so static object detection does
not longer work.
unlock_subsytem_object(addr);
if (is_static_object(addr)) <- Fails
debugobject emits a warning and invokes the fixup function which
reinitializes the already active object in the worst case.
This race exists forever, but was never observed until mod_timer() got a
debug_object_assert_init() added which is outside of the timer base lock
held section right at the beginning of the function to cover the lockless
early exit points too.
Rework the code so that the lookup, the static object check and the
tracking object association happens atomically under the hash bucket
lock. This prevents the issue completely as all callers are serialized on
the hash bucket lock and therefore cannot observe inconsistent state.
Fixes: 3ac7fe5a4aab ("infrastructure to debug (dynamic) objects")

The point of the WARN was to print something, not oops
straight up. Currently that is precisely what happens
if we can't find the connector for the crtc in the atomic
state. Get the dev pointer from the atomic state instead
of the potentially NULL encoder to avoid that.

[ Upstream commit e9523a0d81899361214d118ad60ef76f0e92f71d ]
With HIGHRES enabled tick_sched_timer() is programmed every jiffy to
expire the timer_list timers. This timer is programmed accurate in
respect to CLOCK_MONOTONIC so that 0 seconds and nanoseconds is the
first tick and the next one is 1000/CONFIG_HZ ms later. For HZ=250 it is
every 4 ms and so based on the current time the next tick can be
computed.
This accuracy broke since the commit mentioned below because the jiffy
based clocksource is initialized with higher accuracy in
read_persistent_wall_and_boot_offset(). This higher accuracy is
inherited during the setup in tick_setup_device(). The timer still fires
every 4ms with HZ=250 but timer is no longer aligned with
CLOCK_MONOTONIC with 0 as it origin but has an offset in the us/ns part
of the timestamp. The offset differs with every boot and makes it
impossible for user land to align with the tick.
Align the tick period with CLOCK_MONOTONIC ensuring that it is always a
multiple of 1000/CONFIG_HZ ms.

[ Upstream commit 7a68f9fa97357a0f2073c9c31ed4101da4fce93e ]
As support for splitting transmission over several messages using
TX_DATA_CONT was introduced it does not immediately return the return
value of qcom_glink_tx().
The result is that in the intentless case (i.e. intent == NULL), the
code will continue to send all additional chunks. This is wasteful, and
it's possible that the send operation could incorrectly indicate
success, if the last chunk fits in the TX fifo.
Fix the condition.

[ Upstream commit 93822f5161a2dc57a60b95b35b3cb8589f53413e ]
The bit flags in pmbus_driver_info functionality for YM-2151E chip were
joined with a comma operator instead of a bitwise OR. This means that
the last constant PMBUS_HAVE_IIN was not OR-ed with the other
PM_BUS_HAVE_* constants for this page but it initialized the next element
of the func array (which was not accessed from anywhere because of the
number of pages).
However, there is no need for setting PMBUS_HAVE_IIN in the 5Vsb page
because this command does not seem to be paged. Obviously, the device
only has one IIN sensor, so it doesn't make sense to query it again from
the second page.

[ Upstream commit 7654cc03eb699297130b693ec34e25f77b17c947 ]
hif_dev->remain_skb is allocated and used exclusively in
ath9k_hif_usb_rx_stream(). It is implied that an allocated remain_skb is
processed and subsequently freed (in error paths) only during the next
call of ath9k_hif_usb_rx_stream().
So, if the urbs are deallocated between those two calls due to the device
deinitialization or suspend, it is possible that ath9k_hif_usb_rx_stream()
is not called next time and the allocated remain_skb is leaked. Our local
Syzkaller instance was able to trigger that.
remain_skb makes sense when receiving two consecutive urbs which are
logically linked together, i.e. a specific data field from the first skb
indicates a cached skb to be allocated, memcpy'd with some data and
subsequently processed in the next call to ath9k_hif_usb_rx_stream(). Urbs
deallocation supposedly makes that link irrelevant so we need to free the
cached skb in those cases.
Fix the leak by introducing a function to explicitly free remain_skb (if
it is not NULL) when the rx urbs have been deallocated. remain_skb is NULL
when it has not been allocated at all (hif_dev struct is kzalloced) or
when it has been processed in next call to ath9k_hif_usb_rx_stream().
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

As of commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ
resource from DT core"), we need to use platform_get_irq() instead of
platform_get_resource() to get our IRQs because
platform_get_resource() simply won't get them anymore.
This was already fixed in several other Atheros WiFi drivers,
apparently in response to Zeal Robot reports. An example of another
fix is commit 9503a1fc123d ("ath9k: Use platform_get_irq() to get the
interrupt"). ath11k seems to have been missed in this effort, though.
Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based
hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ,
i)" was failing even for i=0.

[ Upstream commit 4c856ee12df85aabd437c3836ed9f68d94268358 ]
This loop checks that i < max at the start of loop but then it does
i++ which could put it past the end of the array. It's harmless to
check again and prevent a potential out of bounds.

Following the locking pattern for peer_rhash_add lock tbl_mtx_lock mutex
always even if sta is not transitioning to another band.
This is peer_add function and a more secure locking should not cause

From: John Keeping <john@metanate.com>
[ Upstream commit ec52d77d077529f198fd874c550a26b9cc86a331 ]
Using the BCM4339 firmware from linux-firmware (version "BCM4339/2 wl0:
Sep 5 2019 11:05:52 version 6.37.39.113 (r722271 CY)" from
cypress/cyfmac4339-sdio.bin) the RSSI respose is only 4 bytes, which
results in an error being logged.
It seems that older devices send only the RSSI field and neither SNR nor
noise is included. Handle this by accepting a 4 byte message and
reading only the RSSI from it.

[ Upstream commit c679bbd611c08b0559ffae079330bc4e5574696a ]
RFC8259 ("The JavaScript Object Notation (JSON) Data Interchange
Format") only specifies \", \\, \/, \b, \f, \n, \r, and \r as valid
two-character escape sequences. This does not include \', which is not
required in JSON because it exclusively uses double quotes as string
separators.
Solidus (/) may be escaped, but does not have to. Only reverse
solidus (\), double quotes ("), and the control characters have to be
escaped. Therefore, with this fix, bpftool correctly supports all valid
two-character escape sequences (but still does not support characters
that require multi-character escape sequences).
Witout this fix, attempting to load a JSON file generated by bpftool
using Python 3.10.6's default json.load() may fail with the error
"Invalid \escape" if the file contains the invalid escaped single
quote (\').

rtw_mac_power_switch() calls rtw_pwr_seq_parser() which can return
-EINVAL, -EBUSY or 0. Propagate the original error code instead of
unconditionally returning -EINVAL in case of an error.

[ Upstream commit 52c2b005a3c18c565fc70cfd0ca49375f301e952 ]
When doing state comparison, if old state has register that is not
marked as REG_LIVE_READ, then we just skip comparison, regardless what's
the state of corresponing register in current state. This is because not
REG_LIVE_READ register is irrelevant for further program execution and
correctness. All good here.
But when we get to precision propagation, after two states were declared
equivalent, we don't take into account old register's liveness, and thus
attempt to propagate precision for register in current state even if
that register in old state was not REG_LIVE_READ anymore. This is bad,
because register in current state could be anything at all and this
could cause -EFAULT due to internal logic bugs.
Fix by taking into account REG_LIVE_READ liveness mark to keep the logic
in state comparison in sync with precision propagation.

[ Upstream commit 1bdc85550a2b59bb7f62ead7173134e66dd2d60e ]
The sysfs `state` attribute is not protected against race conditions.
If multiple processes perform a device state transition on the same
device in parallel, unexpected behaviors might occur.
For transitioning the device state, adf_sysfs.c calls the functions
adf_dev_init(), adf_dev_start(), adf_dev_stop() and adf_dev_shutdown()
which are unprotected and interdependent on each other. To perform a
state transition, these functions needs to be called in a specific
order:
* device up: adf_dev_init() -> adf_dev_start()
* device down: adf_dev_stop() -> adf_dev_shutdown()
This change introduces the functions adf_dev_up() and adf_dev_down()
which wrap the state machine functions and protect them with a
per-device lock. These are then used in adf_sysfs.c instead of the
individual state transition functions.

[ Upstream commit a02d83f9947d8f71904eda4de046630c3eb6802c ]
Currently, kernel would set MSG_CTRUNC flag if msg_control buffer
wasn't provided and SO_PASSCRED was set or if there was pending SCM_RIGHTS.
For some reason we have no corresponding check for SO_PASSSEC.
In the recvmsg(2) doc we have:
MSG_CTRUNC
indicates that some control data was discarded due to lack
of space in the buffer for ancillary data.
So, we need to set MSG_CTRUNC flag for all types of SCM.
This change can break applications those don't check MSG_CTRUNC flag.

[ Upstream commit 5a78ac33e3cb8822da64dd1af196e83664b332b0 ]
Currently, in ath11k_ahb_fw_resources_init(), iommu domain
mapping is done only for the chipsets having fixed firmware
memory. Also, for such chipsets, mapping is done only if it
does not have TrustZone support.
During deinitialization, only if TrustZone support is not there,
iommu is unmapped back. However, for non fixed firmware memory
chipsets, TrustZone support is not there and this makes the
condition check to true and it tries to unmap the memory which
was not mapped during initialization.
This leads to the following trace -

This can be reproduced by probing an AHB chipset which is not
having a fixed memory region. During reboot (or rmmod) trace
can be seen.
Fix this issue by adding a condition check on firmware fixed memory
hw_param as done in the counter initialization function.

From: Luis Gerhorst <gerhorst@cs.fau.de>
[ Upstream commit 082cdc69a4651dd2a77539d69416a359ed1214f5 ]
For every BPF_ADD/SUB involving a pointer, adjust_ptr_min_max_vals()
ensures that the resulting pointer has a constant offset if
bypass_spec_v1 is false. This is ensured by calling sanitize_check_bounds()
which in turn calls check_stack_access_for_ptr_arithmetic(). There,
-EACCESS is returned if the register's offset is not constant, thereby
rejecting the program.
In summary, an unprivileged user must never be able to create stack
pointers with a variable offset. That is also the case, because a
respective check in check_stack_write() is missing. If they were able
to create a variable-offset pointer, users could still use it in a
stack-write operation to trigger unsafe speculative behavior [1].
Because unprivileged users must already be prevented from creating
variable-offset stack pointers, viable options are to either remove
this check (replacing it with a clarifying comment), or to turn it
into a "verifier BUG"-message, also adding a similar check in
check_stack_write() (for consistency, as a second-level defense).
This patch implements the first option to reduce verifier bloat.
This check was introduced by commit 01f810ace9ed ("bpf: Allow
variable-offset stack access") which correctly notes that
"variable-offset reads and writes are disallowed (they were already
disallowed for the indirect access case) because the speculative
execution checking code doesn't support them". However, it does not
further discuss why the check in check_stack_read() is necessary.
The code which made this check obsolete was also introduced in this
commit.
I have compiled ~650 programs from the Linux selftests, Linux samples,
Cilium, and libbpf/examples projects and confirmed that none of these
trigger the check in check_stack_read() [2]. Instead, all of these
programs are, as expected, already rejected when constructing the
variable-offset pointers. Note that the check in
check_stack_access_for_ptr_arithmetic() also prints "off=%d" while the
code removed by this patch does not (the error removed does not appear
in the "verification_error" values). For reproducibility, the
repository linked includes the raw data and scripts used to create
the plot.

po->auxdata can be read while another thread
is changing its value, potentially raising KCSAN splat.
Convert it to PACKET_SOCK_AUXDATA flag.

[ Upstream commit a506d6ce1dd184051037dc9d26c3eb187c9fe625 ]
Unlike normal libbpf the light skeleton 'loader' program is doing
btf_find_by_name_kind() call at run-time to find ksym in the kernel and
populate its {btf_id, btf_obj_fd} pair in ld_imm64 insn. To avoid doing the
search multiple times for the same ksym it remembers the first patched ld_imm64
insn and copies {btf_id, btf_obj_fd} from it into subsequent ld_imm64 insn.
Fix a bug in copying logic, since it may incorrectly clear BPF_PSEUDO_BTF_ID flag.
Also replace always true if (btf_obj_fd >= 0) check with unconditional JMP_JA
to clarify the code.

From: JP Kobryn <inwardvessel@gmail.com>
[ Upstream commit d7ba4cc900bf1eea2d8c807c6b1fc6bd61f41237 ]
This patch changes the return types of bpf_map_ops functions to long, where
previously int was returned. Using long allows for bpf programs to maintain
the sign bit in the absence of sign extension during situations where
inlined bpf helper funcs make calls to the bpf_map_ops funcs and a negative
error is returned.
The definitions of the helper funcs are generated from comments in the bpf
uapi header at `include/uapi/linux/bpf.h`. The return type of these
helpers was previously changed from int to long in commit bdb7b79b4ce8. For
any case where one of the map helpers call the bpf_map_ops funcs that are
still returning 32-bit int, a compiler might not include sign extension
instructions to properly convert the 32-bit negative value a 64-bit
negative value.
For example:
bpf assembly excerpt of an inlined helper calling a kernel function and
checking for a specific error:
; err = bpf_map_update_elem(&mymap, &key, &val, BPF_NOEXIST);
...
46: call 0xffffffffe103291c ; htab_map_update_elem
; if (err && err != -EEXIST) {
4b: cmp $0xffffffffffffffef,%rax ; cmp -EEXIST,%rax
kernel function assembly excerpt of return value from
`htab_map_update_elem` returning 32-bit int:
movl $0xffffffef, %r9d
...
movl %r9d, %eax
...results in the comparison:
cmp $0xffffffffffffffef, $0x00000000ffffffef

[ Upstream commit 7be14c1c9030f73cc18b4ff23b78a0a081f16188 ]
Xu reports that after commit 3f50f132d840 ("bpf: Verifier, do explicit ALU32
bounds tracking"), the following BPF program is rejected by the verifier:
0: (61) r2 = *(u32 *)(r1 +0) ; R2_w=pkt(off=0,r=0,imm=0)
1: (61) r3 = *(u32 *)(r1 +4) ; R3_w=pkt_end(off=0,imm=0)
2: (bf) r1 = r2
3: (07) r1 += 1
4: (2d) if r1 > r3 goto pc+8
5: (71) r1 = *(u8 *)(r2 +0) ; R1_w=scalar(umax=255,var_off=(0x0; 0xff))
6: (18) r0 = 0x7fffffffffffff10
8: (0f) r1 += r0 ; R1_w=scalar(umin=0x7fffffffffffff10,umax=0x800000000000000f)
9: (18) r0 = 0x8000000000000000
11: (07) r0 += 1
12: (ad) if r0 < r1 goto pc-2
13: (b7) r0 = 0
14: (95) exit
And the verifier log says:

The 64bit umin=9223372036854775810 bound continuously bumps by +1 while
umax=9223372036854775823 stays as-is until the verifier complexity limit
is reached and the program gets finally rejected. During this simulation,
the umin also eventually surpasses umax. Looking at the first 'from 12
to 11' output line from the loop, R1 has the following state:
R1_w=scalar(umin=0x8000000000000002 (9223372036854775810),
umax=0x800000000000000f (9223372036854775823),
var_off=(0x8000000000000000;
0xffffffff))
The var_off has technically not an inconsistent state but it's very
imprecise and far off surpassing 64bit umax bounds whereas the expected
output with refined known bits in var_off should have been like:
R1_w=scalar(umin=0x8000000000000002 (9223372036854775810),
umax=0x800000000000000f (9223372036854775823),
var_off=(0x8000000000000000;
0xf))
In the above log, var_off stays as var_off=(0x8000000000000000; 0xffffffff)
and does not converge into a narrower mask where more bits become known,
eventually transforming R1 into a constant upon umin=9223372036854775823,
umax=9223372036854775823 case where the verifier would have terminated and
let the program pass.
The __reg_combine_64_into_32() marks the subregister unknown and propagates
64bit {s,u}min/{s,u}max bounds to their 32bit equivalents iff they are within
the 32bit universe. The question came up whether __reg_combine_64_into_32()
should special case the situation that when 64bit {s,u}min bounds have
the same value as 64bit {s,u}max bounds to then assign the latter as
well to the 32bit reg->{s,u}32_{min,max}_value. As can be seen from the
above example however, that is just /one/ special case and not a /generic/
solution given above example would still not be addressed this way and
remain at an imprecise var_off=(0x8000000000000000; 0xffffffff).
The improvement is needed in __reg_bound_offset() to refine var32_off with
the updated var64_off instead of the prior reg->var_off. The reg_bounds_sync()
code first refines information about the register's min/max bounds via
__update_reg_bounds() from the current var_off, then in __reg_deduce_bounds()
from sign bit and with the potentially learned bits from bounds it'll
update the var_off tnum in __reg_bound_offset(). For example, intersecting
with the old var_off might have improved bounds slightly, e.g. if umax
was 0x7f...f and var_off was (0; 0xf...fc), then new var_off will then
result in (0; 0x7f...fc). The intersected var64_off holds then the
universe which is a superset of var32_off. The point for the latter is
not to broaden, but to further refine known bits based on the intersection
of var_off with 32 bit bounds, so that we later construct the final var_off
from upper and lower 32 bits. The final __update_reg_bounds() can then
potentially still slightly refine bounds if more bits became known from the
new var_off.
After the improvement, we can see R1 converging successively:

[ Upstream commit becd9be6069e7b183c084f460f0eb363e43cc487 ]
iSCSI needs to wait on outstanding commands like how SRP and the FC/FCoE
drivers do. It can't use target_stop_session() because for MCS support we
can't stop the entire session during recovery because if other connections
are OK then we want to be able to continue to execute I/O on them.
Move the per session cmd counters to a new struct so iSCSI can allocate
them per connection. The xcopy code can also just not allocate in the
future since it doesn't need to track commands.

From: Mike Christie <michael.christie@oracle.com>
[ Upstream commit 4edba7e4a8f39112398d3cda94128a8e13a7d527 ]
iSCSI needs to allocate its cmd counter per connection for MCS support
where we need to stop and wait on commands running on a connection instead
of per session. This moves the cmd counter allocation to
target_setup_session() which is used by drivers that need the stop+wait
behavior per session.
xcopy doesn't need stop+wait at all, so we will be OK moving the cmd
counter allocation outside of transport_init_session().

[ Upstream commit 8e288be8606ad87c1726618eacfb8fbd3ab4b806 ]
Allow target_get_sess_cmd() users to pass in the cmd counter they want to
use. Right now we pass in the session's cmd counter but in a subsequent
commit iSCSI will switch from per session to per conn.

[ Upstream commit 395cee83d02de3073211b04fc85724f4abc663ad ]
This fixes a bug added in commit f36199355c64 ("scsi: target: iscsi: Fix
cmd abort fabric stop race").
If we have multiple sessions to the same se_device we can hit a race where
a LUN_RESET on one session cleans up the se_cmds from under another
session which is being closed. This results in the closing session freeing
its conn/session structs while they are still in use.
The bug is:
1. Session1 has IO se_cmd1.
2. Session2 can also have se_cmds for I/O and optionally TMRs for ABORTS
but then gets a LUN_RESET.
3. The LUN_RESET on session2 sees the se_cmds on session1 and during the
drain stages marks them all with CMD_T_ABORTED.
4. session1 is now closed so iscsit_release_commands_from_conn() only sees
se_cmds with the CMD_T_ABORTED bit set and returns immediately even
though we have outstanding commands.
5. session1's connection and session are freed.
6. The backend request for se_cmd1 completes and it accesses the freed
connection/session.
This hooks the iscsit layer into the cmd counter code, so we can wait for
all outstanding se_cmds before freeing the connection.

[ Upstream commit 673db054d7a2b5a470d7a25baf65956d005ad729 ]
This fixes a bug where an initiator thinks a LUN_RESET has cleaned up
running commands when it hasn't. The bug was added in commit 51ec502a3266
("target: Delete tmr from list before processing").
The problem occurs when:
1. We have N I/O cmds running in the target layer spread over 2 sessions.
2. The initiator sends a LUN_RESET for each session.
3. session1's LUN_RESET loops over all the running commands from both
sessions and moves them to its local drain_task_list.
4. session2's LUN_RESET does not see the LUN_RESET from session1 because
the commit above has it remove itself. session2 also does not see any
commands since the other reset moved them off the state lists.
5. sessions2's LUN_RESET will then complete with a successful response.
6. sessions2's inititor believes the running commands on its session are
now cleaned up due to the successful response and cleans up the running
commands from its side. It then restarts them.
7. The commands do eventually complete on the backend and the target
starts to return aborted task statuses for them. The initiator will
either throw a invalid ITT error or might accidentally lookup a new
task if the ITT has been reallocated already.
Fix the bug by reverting the patch, and serialize the execution of
LUN_RESETs and Preempt and Aborts.
Also prevent us from waiting on LUN_RESETs in core_tmr_drain_tmr_list,
because it turns out the original patch fixed a bug that was not
mentioned. For LUN_RESET1 core_tmr_drain_tmr_list can see a second
LUN_RESET and wait on it. Then the second reset will run
core_tmr_drain_tmr_list and see the first reset and wait on it resulting in
a deadlock.

Fix a bug added in commit f36199355c64 ("scsi: target: iscsi: Fix cmd abort
fabric stop race").
If CMD_T_TAS is set on the se_cmd we must call iscsit_free_cmd() to do the
last put on the cmd and free it, because the connection is down and we will
not up sending the response and doing the put from the normal I/O
path.
Add a check for CMD_T_TAS in iscsit_release_commands_from_conn() so we now
detect this case and run iscsit_free_cmd().

When f2fs skipped a gc round during victim migration, there was a bug which
would skip all upcoming gc rounds unconditionally because skipped_gc_rwsem
was not initialized. It fixes the bug by correctly initializing the
skipped_gc_rwsem inside the gc loop.

If we manage the zone capacity per zone type, it'll break the GC assumption.
And, the current logic complains valid block count mismatch.
Let's apply zone capacity to all zone type, if specified.

Below is the concurrency scenario:
[Process A] [Process B] [Process C]
f2fs_write_raw_pages()
- redirty_page_for_writepage()
- unlock page()
f2fs_do_write_data_page()
- lock_page()

- set_page_writeback() [1st writeback]
.....
- unlock page()

- f2fs_write_end()
- set_page_dirty()
- lock_page()
- f2fs_do_write_data_page()
- set_page_writeback() [2st writeback]
This problem was introduced by the previous commit 7377e853967b ("f2fs:
compress: fix potential deadlock of compress file"). All pagelocks were
released in f2fs_write_raw_pages(), but whether the page was
in the writeback state was ignored in the subsequent writing process.
Let's fix it by waiting for the page to writeback before writing.

According to the comment at the end of the 'for' loop just a few lines
below, it looks needed to clear 'desc'.
So it should also be cleared for the first iteration.
Move the memset() to the beginning of the loop to be safe.

[ Upstream commit 8832023efd20966e29944dac92118dfbf1fa1bc0 ]
The SA2UL Crypto driver provides support for couple of
DES3 algos "cbc(des3_ede)" and "ecb(des3_ede)", and enabling
the crypto selftest throws the following errors (as seen on
K3 J721E SoCs):
saul-crypto 4e00000.crypto: Error allocating fallback algo cbc(des3_ede)
alg: skcipher: failed to allocate transform for cbc-des3-sa2ul: -2
saul-crypto 4e00000.crypto: Error allocating fallback algo ecb(des3_ede)
alg: skcipher: failed to allocate transform for ecb-des3-sa2ul: -2
Fix this by selecting CRYPTO_DES which was missed while
adding base driver support.

[ Upstream commit bb544224da77b96b2c11a13872bf91ede1e015be ]
If an NCQ error occurs when the IPTT is valid and slot->abort flag is set
in completion path, sas_task_abort() will be called to abort only one NCQ
command now, and the host would be set to SHOST_RECOVERY state. But this
may not kick-off EH Immediately until other outstanding QCs timeouts. As a
result, the host may remain in the SHOST_RECOVERY state for up to 30
seconds, such as follows:

All NCQ commands that are in the queue should be aborted when an NCQ error
occurs in this scenario.

[ Upstream commit 30465003ad776a922c32b2dac58db14f120f037e ]
Many of the structs recently added to track field info for linked-list
head are useful as-is for rbtree root. So let's do a mechanical renaming
of list_head-related types and fields:
include/linux/bpf.h:
struct btf_field_list_head -> struct btf_field_graph_root
list_head -> graph_root in struct btf_field union
kernel/bpf/btf.c:
list_head -> graph_root in struct btf_field_info
This is a nonfunctional change, functionality to actually use these
fields for rbtree will be added in further patches.

[ Upstream commit 57e7c169cd6afa093d858b8edfb9bceaf2e1c93b ]
kfuncs are functions defined in the kernel, which may be invoked by BPF
programs. They may or may not also be used as regular kernel functions,
implying that they may be static (in which case the compiler could e.g.
inline it away, or elide one or more arguments), or it could have
external linkage, but potentially be elided in an LTO build if a
function is observed to never be used, and is stripped from the final
kernel binary.
This has already resulted in some issues, such as those discussed in [0]
wherein changes in DWARF that identify when a parameter has been
optimized out can break BTF encodings (and in general break the kfunc).
[0]: https://lore.kernel.org/all/1675088985-20300-2-git-send-email-alan.maguire@oracle.com/
We therefore require some convenience macro that kfunc developers can
use just add to their kfuncs, and which will prevent all of the above
issues from happening. This is in contrast with what we have today,
where some kfunc definitions have "noinline", some have "__used", and
others are static and have neither.
Note that longer term, this mechanism may be replaced by a macro that
more closely resembles EXPORT_SYMBOL_GPL(), as described in [1]. For
now, we're going with this shorter-term approach to fix existing issues
in kfuncs.
[1]: https://lore.kernel.org/lkml/Y9AFT4pTydKh+PD3@maniforge.lan/
Note as well that checkpatch complains about this patch with the
following:
ERROR: Macros with complex values should be enclosed in parentheses
+#define __bpf_kfunc __used noinline
There seems to be a precedent for using this pattern in other places
such as compiler_types.h (see e.g. __randomize_layout and noinstr), so
it seems appropriate.

[ Upstream commit 6a3cd3318ff65622415e34e8ee39d76331e7c869 ]
This patch introduces non-owning reference semantics to the verifier,
specifically linked_list API kfunc handling. release_on_unlock logic for
refs is refactored - with small functional changes - to implement these
semantics, and bpf_list_push_{front,back} are migrated to use them.
When a list node is pushed to a list, the program still has a pointer to
the node:
n = bpf_obj_new(typeof(*n));
bpf_spin_lock(&l);
bpf_list_push_back(&l, n);
/* n still points to the just-added node */
bpf_spin_unlock(&l);
What the verifier considers n to be after the push, and thus what can be
done with n, are changed by this patch.
Common properties both before/after this patch:
* After push, n is only a valid reference to the node until end of
critical section
* After push, n cannot be pushed to any list
* After push, the program can read the node's fields using n
Before:
* After push, n retains the ref_obj_id which it received on
bpf_obj_new, but the associated bpf_reference_state's
release_on_unlock field is set to true
* release_on_unlock field and associated logic is used to implement
"n is only a valid ref until end of critical section"
* After push, n cannot be written to, the node must be removed from
the list before writing to its fields
* After push, n is marked PTR_UNTRUSTED
After:
* After push, n's ref is released and ref_obj_id set to 0. NON_OWN_REF
type flag is added to reg's type, indicating that it's a non-owning
reference.
* NON_OWN_REF flag and logic is used to implement "n is only a
valid ref until end of critical section"
* n can be written to (except for special fields e.g. bpf_list_node,
timer, ...)
Summary of specific implementation changes to achieve the above:
* release_on_unlock field, ref_set_release_on_unlock helper, and logic
to "release on unlock" based on that field are removed
* The anonymous active_lock struct used by bpf_verifier_state is
pulled out into a named struct bpf_active_lock.
* NON_OWN_REF type flag is introduced along with verifier logic
changes to handle non-owning refs
* Helpers are added to use NON_OWN_REF flag to implement non-owning
ref semantics as described above
* invalidate_non_owning_refs - helper to clobber all non-owning refs
matching a particular bpf_active_lock identity. Replaces
release_on_unlock logic in process_spin_lock.
* ref_set_non_owning - set NON_OWN_REF type flag after doing some
sanity checking
* ref_convert_owning_non_owning - convert owning reference w/
specified ref_obj_id to non-owning references. Set NON_OWN_REF
flag for each reg with that ref_obj_id and 0-out its ref_obj_id
* Update linked_list selftests to account for minor semantic
differences introduced by this patch
* Writes to a release_on_unlock node ref are not allowed, while
writes to non-owning reference pointees are. As a result the
linked_list "write after push" failure tests are no longer scenarios
that should fail.
* The test##missing_lock##op and test##incorrect_lock##op
macro-generated failure tests need to have a valid node argument in
order to have the same error output as before. Otherwise
verification will fail early and the expected error output won't be seen.

[ Upstream commit 9c395c1b99bd23f74bc628fa000480c49593d17f ]
This patch adds special BPF_RB_{ROOT,NODE} btf_field_types similar to
BPF_LIST_{HEAD,NODE}, adds the necessary plumbing to detect the new
types, and adds bpf_rb_root_free function for freeing bpf_rb_root in
map_values.
structs bpf_rb_root and bpf_rb_node are opaque types meant to
obscure structs rb_root_cached rb_node, respectively.
btf_struct_access will prevent BPF programs from touching these special
fields automatically now that they're recognized.
btf_check_and_fixup_fields now groups list_head and rb_root together as
"graph root" fields and {list,rb}_node as "graph node", and does same
ownership cycle checking as before. Note that this function does _not_
prevent ownership type mixups (e.g. rb_root owning list_node) - that's
handled by btf_parse_graph_root.
After this patch, a bpf program can have a struct bpf_rb_root in a
map_value, but not add anything to nor do anything useful with it.

[ Upstream commit bd1279ae8a691d7ec75852c6d0a22139afb034a4 ]
This patch adds implementations of bpf_rbtree_{add,remove,first}
and teaches verifier about their BTF_IDs as well as those of
bpf_rb_{root,node}.
All three kfuncs have some nonstandard component to their verification
that needs to be addressed in future patches before programs can
properly use them:
* bpf_rbtree_add: Takes 'less' callback, need to verify it
* bpf_rbtree_first: Returns ptr_to_node_type(off=rb_node_off) instead
of ptr_to_rb_node(off=0). Return value ref is
non-owning.
* bpf_rbtree_remove: Returns ptr_to_node_type(off=rb_node_off) instead
of ptr_to_rb_node(off=0). 2nd arg (node) is a
non-owning reference.

[ Upstream commit cd6791b4b6f66f6b7925c840efe5c8fa0ce1ac87 ]
Now that we find bpf_rb_root and bpf_rb_node in structs, let's give args
that contain those types special classification and properly handle
these types when checking kfunc args.
"Properly handling" these types largely requires generalizing similar
handling for bpf_list_{head,node}, with little new logic added in this
patch.

[ Upstream commit 5d92ddc3de1b44a82108af68ed71f638ca20509a ]
Some BPF helpers take a callback function which the helper calls. For
each helper that takes such a callback, there's a special call to
__check_func_call with a callback-state-setting callback that sets up
verifier bpf_func_state for the callback's frame.
kfuncs don't have any of this infrastructure yet, so let's add it in
this patch, following existing helper pattern as much as possible. To
validate functionality of this added plumbing, this patch adds
callback handling for the bpf_rbtree_add kfunc and hopes to lay
groundwork for future graph datastructure callbacks.
In the "general plumbing" category we have:
* check_kfunc_call doing callback verification right before clearing
CALLER_SAVED_REGS, exactly like check_helper_call
* recognition of func_ptr BTF types in kfunc args as
KF_ARG_PTR_TO_CALLBACK + propagation of subprogno for this arg type
In the "rbtree_add / graph datastructure-specific plumbing" category:
* Since bpf_rbtree_add must be called while the spin_lock associated
with the tree is held, don't complain when callback's func_state
doesn't unlock it by frame exit
* Mark rbtree_add callback's args with ref_set_non_owning
to prevent rbtree api functions from being called in the callback.
Semantically this makes sense, as less() takes no ownership of its
args when determining which comes first.

[ Upstream commit 07236eab7a3139da97aef9f5f21f403be82a82ea ]
Factor out logic to fetch basic kfunc metadata based on struct bpf_insn.
This is not exactly short or trivial code to just copy/paste and this
information is sometimes necessary in other parts of the verifier logic.
Subsequent patches will rely on this to determine if an instruction is
a kfunc call to iterator next method.
No functional changes intended, including that verbose() warning
behavior when kfunc is not allowed for a particular program type.

[ Upstream commit f6a6a5a976288e4d0d94eb1c6c9e983e8e5cdb31 ]
bpf_obj_drop_impl has a void return type. In check_kfunc_call, the "else
if" which sets insn_aux->kptr_struct_meta for bpf_obj_drop_impl is
surrounded by a larger if statement which checks btf_type_is_ptr. As a
result:
* The bpf_obj_drop_impl-specific code will never execute
* The btf_struct_meta input to bpf_obj_drop is always NULL
* __bpf_obj_drop_impl will always see a NULL btf_record when called
from BPF program, and won't call bpf_obj_free_fields
* program-allocated kptrs which have fields that should be cleaned up
by bpf_obj_free_fields may instead leak resources
This patch adds a btf_type_is_void branch to the larger if and moves
special handling for bpf_obj_drop_impl there, fixing the issue.

[ Upstream commit f2b50f17268390567bc0e95642170d88f336c8f4 ]
This change fixes flakiness in the BIDIRECTIONAL test:
# [is_pkt_valid] expected length [60], got length [90]
not ok 1 FAIL: SKB BUSY-POLL BIDIRECTIONAL
When IPv6 is enabled, the interface will periodically send MLDv1 and
MLDv2 packets. These packets can cause the BIDIRECTIONAL test to fail
since it uses VETH0 for RX.
For other tests, this was not a problem since they only receive on VETH1
and IPv6 was already disabled on VETH0.

[ Upstream commit 68e7322142f5e731af222892d384d311835db0f1 ]
Fix flaky STATS_RX_DROPPED test. The receiver calls getsockopt after
receiving the last (valid) packet which is not the final packet sent in
the test (valid and invalid packets are sent in alternating fashion with
the final packet being invalid). Since the last packet may or may not
have been dropped already, both outcomes must be allowed.
This issue could also be fixed by making sure the last packet sent is
valid. This alternative is left as an exercise to the reader (or the
benevolent maintainers of this file).
This problem was quite visible on certain setups. On one machine this
failure was observed 50% of the time.
Also, remove a redundant assignment of pkt_stream->nb_pkts. This field
is already initialized by __pkt_stream_alloc.

[ Upstream commit 5af607a861d43ffff830fc1890033e579ec44799 ]
In some cases the loopback latency might be large enough, causing
the assertion on invocations to be run before ingress prog getting
executed. The assertion would fail and the test would flake.
This can be reliably reproduced by arbitrarily increasing the
loopback latency (thanks to [1]):
tc qdisc add dev lo root handle 1: htb default 12
tc class add dev lo parent 1:1 classid 1:12 htb rate 20kbps ceil 20kbps
tc qdisc add dev lo parent 1:12 netem delay 100ms
Fix this by waiting on the receive end, instead of instantly
returning to the assert. The call to read() will wait for the
default SO_RCVTIMEO timeout of 3 seconds provided by
start_server().

Make sure unaligned descriptors that straddle the end of the UMEM are
considered invalid. Currently, descriptor validation is broken for
zero-copy mode which only checks descriptors at page granularity.
For example, descriptors in zero-copy mode that overrun the end of the
UMEM but not a page boundary are (incorrectly) considered valid. The
UMEM boundary check needs to happen before the page boundary and
contiguity checks in xp_desc_crosses_non_contig_pg(). Do this check in
xp_unaligned_validate_desc() instead like xp_check_unaligned() already
does.

The root cause is: after cp_error is set, f2fs_submit_merged_ipu_write()
in f2fs_write_single_data_page() tries to flush IPU bio in cache, however
f2fs_submit_merged_ipu_write() missed to check validity of @bio parameter,
result in submitting random cached bio which belong to other IO context,
then it will cause use-after-free issue, fix it by adding additional
validity check.

[ Upstream commit 91f2dc6838c19342f7f2993627c622835cc24890 ]
When tracing a kernel function with arg type is u32*, btf_ctx_access()
would report error: arg2 type INT is not a struct.
The commit bb6728d75611 ("bpf: Allow access to int pointer arguments
in tracing programs") added support for int pointer, but did not skip
modifiers before checking it's type. This patch fixes it.

[ Upstream commit 91a0c0c1413239d0548b5aac4c82f38f6d53a91e ]
When if_type equals zero and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns false, drbl_regs_memmap_p is not remapped. This passes a NULL
pointer to iounmap(), which can trigger a WARN() on certain arches.
When if_type equals six and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns true, drbl_regs_memmap_p may has been remapped and
ctrl_regs_memmap_p is not remapped. This is a resource leak and passes a
NULL pointer to iounmap().
To fix these issues, we need to add null checks before iounmap(), and
change some goto labels.

[ Upstream commit ea449f7fa0bf3fcd02e04a770b9ff707bf5e8f96 ]
The clock requesting code is quite repetitive. Fix this by requesting
the clocks via devm_clk_bulk_get_optional. The optional variant has been
used, since this is effectively what the old code did. The exact clocks
required depend on the platform and configuration. As a side effect
this change adds correct -EPROBE_DEFER handling.

[ Upstream commit db21973263f8c56750cb610f1d5e8bee00a513b9 ]
The usual devm_regulator_get() call already handles "optional"
regulators by returning a valid dummy and printing a warning
that the dummy regulator should be described properly. This
code open coded the same behaviour, but masked any errors that
are not -EPROBE_DEFER and is quite noisy.
This change effectively unmasks and propagates regulators errors
not involving -ENODEV, downgrades the error print to warning level
if no regulator is specified and captures the probe defer message
for /sys/kernel/debug/devices_deferred.

While initializing spectral, the magic value is getting written to the
invalid memory address leading to random boot-up crash. This occurs
due to the incorrect index increment in ath11k_dbring_fill_magic_value
function. Fix it by replacing the existing logic with memset32 to ensure
there is no invalid memory access.

From: Xin Liu <liuxin350@huawei.com>
[ Upstream commit ed17aa92dc56b6d8883e4b7a8f1c6fbf5ed6cd29 ]
When huang uses sched_switch tracepoint, the tracepoint
does only one thing in the mounted ebpf program, which
deletes the fixed elements in sockhash ([0])
It seems that elements in sockhash are rarely actively
deleted by users or ebpf program. Therefore, we do not
pay much attention to their deletion. Compared with hash
maps, sockhash only provides spin_lock_bh protection.
This causes it to appear to have self-locking behavior
in the interrupt context.

[ Upstream commit ab76e7206b672b2e8818cb121a04506956d6b223 ]
Nvme specifications state that:
If the I/O Command Set associated with the namespace identified by the
NSID field does not support the Identify Namespace data structure
specified by the CSI field, the controller shall abort the command with
a status code of Invalid Field in Command.
In other words, if nvmet_execute_identify_cns_cs_ns() is called for a
target with a block device that is not zoned, we should not return any
data and set the status to NVME_SC_INVALID_FIELD.
While at it, it is also better to revalidate the ns block devie *before*
checking if the block device is zoned, to ensure that
nvmet_execute_identify_cns_cs_ns() operates against updated device
characteristics.

[ Upstream commit 8c098aa00118c35108f0c19bd3cdc45e11574948 ]
The identify command with cns set to NVME_ID_CNS_NS does not directly
depend on the command set. The NVMe specifications is rather confusing
here as it appears that this command only applies to the NVM command
set. However, footnote 8 of Figure 273 in the NVMe 2.0 base
specifications clearly state that this command applies to NVM command
sets that support logical blocks, that is, NVM and ZNS. Both the NVM and
ZNS command set specifications also list this identify as mandatory.
The command handling should thus not look at the csi field since it is
defined as unused for this command. Given that we do not support the
KV command set, simply remove the csi switch-case for that command
handling and call directly nvmet_execute_identify_ns() in
nvmet_execute_identify().

[ Upstream commit 97416f67d55fb8b866ff1815ca7ef26b6dfa6a5e ]
The identify command with cns set to NVME_ID_CNS_NS_ACTIVE_LIST does
not depend on the command set. The execution of this command should
thus not look at the csi field specified in the command. Simplify
nvmet_execute_identify() to directly call
nvmet_execute_identify_nslist() without the csi switch-case.

[ Upstream commit a5a6ab0950b46ab1ef4a5c83c80234018b81b38a ]
For an identify command with cns set to NVME_ID_CNS_CS_CTRL, the NVMe
2.0 specification states that:
If the I/O Command Set specified by the CSI field does not have an
Identify Controller data structure, then the controller shall return
a zero filled data structure. If the host requests a data structure for
an I/O Command Set that the controller does not support, the controller
shall abort the command with a status code of Invalid Field in Command.
However, the current implementation of this identify command in
nvmet_execute_identify() only handles the ZNS command set, returning an
error for the NVM command set, which is not compliant with the
specifications as we do support this command set.
Fix this by:
1) Renaming nvmet_execute_identify_cns_cs_ctrl() to
nvmet_execute_identify_ctrl_zns() to continue handling the
ZNS command set as is.
2) Introduce a nvmet_execute_identify_ctrl_ns() helper to handle the
NVM command set, returning a zero filled nvme_id_ctrl_nvm data
structure.
3) Modify nvmet_execute_identify() to call these helpers based on
the csi specified, returning an error for unsupported command sets.

[ Upstream commit 4f86a6ff6fbd891232dda3ca97fd1b9630b59809 ]
fcloop_fcp_op() could be called from flush request's ->end_io(flush_end_io) in
which the spinlock of fq->mq_flush_lock is grabbed with irq saved/disabled.
So fcloop_fcp_op() can't call spin_unlock_irq(&tfcp_req->reqlock) simply
which enables irq unconditionally.
Fixes the warning by switching to spin_lock_irqsave()/spin_unlock_irqrestore()

[ Upstream commit de6d014a09bf12a9a8959d60c0a1d4a41d394a89 ]
Currently, perf_event sample period in perf_event_stackmap is set too low
that the test fails randomly. Fix this by using the max sample frequency,
from read_perf_max_sample_freq().
Move read_perf_max_sample_freq() to testing_helpers.c. Replace the CHECK()
with if-printf, as CHECK is not available in testing_helpers.c.

[ Upstream commit 634c7b1bd08ca322537ab389f8cbd7bb543b5e45 ]
In __iwl_err(), if we rate-limit the message away, then
vaf.va is still NULL-initialized by the time we get to
the tracing code, which then crashes. When it doesn't
get rate-limited out, it's still wrong to reuse the old
args2 that was already printed, which is why we bother
making a copy in the first place.
Assign vaf.va properly to fix this.

there is no need to also set the doorbell. Setting also the

[ Upstream commit 72c215ed8731c88b2d7e09afc51fffc207ae47b8 ]
commit fe630de009d0 ("md/raid10: avoid deadlock on recovery.") allowed
normal io and sync io to exist at the same time. Task hung will occur as
below:
T1 T2 T3 T4
raid10d
handle_read_error

-> 0
//submit sync io
raid10_sync_request
raise_barrier

conf->nr_pending++
-> 1
//retry read fail
raid10_end_read_request
reschedule_retry
add to retry_list
conf->nr_queued++
-> 1
//sync io fail
end_sync_read
__end_sync_read
reschedule_retry
add to retry_list
conf->nr_queued++
-> 2
...
handle_read_error
get form retry_list
conf->nr_queued--
freeze_array
wait nr_pending == nr_queued+1
->1 ->2
//task hung
retry read and sync io will be added to retry_list(nr_queued->2) if they
fails. raid10d() called handle_read_error() and hung in freeze_array().
nr_queued will not decrease because raid10d is blocked, nr_pending will
not increase because conf->barrier is not released.
Fix it by moving allow_barrier() after raid10_read_request().
raise_barrier() will wait for nr_waiting to become 0. Therefore, sync io
and regular io will not be issued at the same time.
Also remove the check of nr_queued in stop_waiting_barrier. It can be 0
but don't need to be blocking. Remove the check for MD_RECOVERY_RUNNING as
the check is redundent.

[ Upstream commit 26208a7cffd0c7cbf14237ccd20c7270b3ffeb7e ]
raid10_sync_request() will add 'r10bio->remaining' for both rdev and
replacement rdev. However, if the read io fails, recovery_request_write()
returns without issuing the write io, in this case, end_sync_request()
is only called once and 'remaining' is leaked, cause an io hang.
Fix the problem by decreasing 'remaining' according to if 'bio' and
'repl_bio' is valid.

In raid10_run(), if setup_conf() succeed and raid10_run() failed before
setting 'mddev->thread', then in the error path 'conf->thread' is not

Fix the problem by setting 'mddev->thread' right after setup_conf().

handle_read_error() will resumit r10_bio by raid10_read_request(), which

[ Upstream commit bd159398a2d2234de07d310132865706964aaaa7 ]
When invalidating buffers under the partial tail page,
jbd2_journal_invalidate_folio() returns -EBUSY if the buffer is part of
the committing transaction as we cannot safely modify buffer state.
However if the buffer is already invalidated (due to previous
invalidation attempts from ext4_wait_for_tail_page_commit()), there's
nothing to do and there's no point in returning -EBUSY. This fixes
occasional warnings from ext4_journalled_invalidate_folio() triggered by
generic/051 fstest when blocksize < pagesize.

Should not use AND operator to check vif type NL80211_IFTYPE_MONITOR, and
that will cause we go into sniffer command for both STA and MONITOR
mode. However, the sniffer command would set channel properly (with some
extra options), the STA mode still works even if using the wrong
command.
Fix vif type check to make sure we using the right command to update
channel.

mt7921 just stop some workers and clean up chip status before reboot.
In stress test, there are working activities still running at the period
of .shutdown callback and that would cause some hosts cannot recover
DMA after reboot. To avoid the floating state in reboot, we use
mt7921_pci_remove() to fully deinit all resources.

[ Upstream commit 90fb69212c60e26ef70ed0e8532b116c7649ac88 ]
On MT7986 the WiFi driver currently does not get automatically loaded,
requiring manual modprobing because the device tree compatibles are not
exported into metadata.
Add the missing MODULE_DEVICE_TABLE macro to fix this.

include the length of general rxd. It only includes the length of

[ Upstream commit c397fc1e6365a2a9e5540a85b2c1d4ea412aa0e2 ]
In system warm reboot scene, due to the polling timeout(now 1000us)
is too short to wait dma idle in time, it may make driver probe fail
with error code -ETIMEDOUT. Meanwhile, we also found the dma may take
around 70ms to enter idle state. Change the polling idle timeout to
100ms to avoid the probabilistic probe fail.
Tested pass with 5000 times warm reboot on x86 platform.

[ Upstream commit 12db28c3ef31f719bd18fa186a40bb152e6a527c ]
The MT7921 driver no longer uses eeprom.data, but the relevant code has not
been removed completely since
commit 16d98b548365 ("mt76: mt7921: rely on mcu_get_nic_capability").
This could result in potential invalid memory access.
To fix the kernel panic issue in mt7921, it is necessary to avoid accessing
unallocated eeprom.data which can lead to invalid memory access.
Furthermore, it is possible to entirely eliminate the
mt7921_mcu_parse_eeprom function and solely depend on
mt7921_mcu_parse_response to divide the RxD header.

[ Upstream commit 87714bf6ed1589813e473db5471e6e9857755764 ]
The hardware team has advised the driver that it is necessary to first put
WFDMA into an idle state before resetting the WFDMA. Otherwise, the WFDMA
may enter an unknown state where it cannot be polled with the right state
successfully. To ensure that the DMA can work properly while a stressful
cold reboot test was being made, we have reordered the programming sequence
in the driver based on the hardware team's guidance.
The patch would modify the WFDMA disabling flow from
"DMA reset -> disabling DMASHDL -> disabling WFDMA -> polling and waiting
until DMA idle" to "disabling WFDMA -> polling and waiting for DMA idle ->
disabling DMASHDL -> DMA reset.
Where he polling and waiting until WFDMA is idle is coordinated with the
operation of disabling WFDMA. Even while WFDMA is being disabled, it can
still handle Tx/Rx requests. The additional polling allows sufficient time
for WFDMA to process the last T/Rx request. When the idle state of WFDMA is
reached, it is a reliable indication that DMASHDL is also idle to ensure it
is safe to disable it and perform the DMA reset.

[ Upstream commit 3d78c46423c6567ed25ca033e086865b1b4d5ae1 ]
If the chip reset worker is triggered during the remove process, the chip
DMA may not be properly pushed back to the idle state. This can lead to
corruption of the DMA flow due to the chip reset. Therefore, it is
necessary to stop the chip reset before the DMA is finalized.
To avoid resetting the chip after the reset worker is cancelled, use
__mt7921_mcu_drv_pmctrl() instead of mt7921_mcu_drv_pmctrl(). It is safe to
ignore the pm mutex because the pm worker and wake worker have already been
cancelled.

e6d57e9ff0ae ("netfilter: conntrack: fix rmmod double-free race")
consolidates IPS_CONFIRMED bit set in nf_conntrack_hash_check_insert().
However, this breaks ctnetlink:
# conntrack -I -p tcp --timeout 123 --src 1.2.3.4 --dst 5.6.7.8 --state ESTABLISHED --sport 1 --dport 4 -u SEEN_REPLY
conntrack v1.4.6 (conntrack-tools): Operation failed: Device or resource busy
This is a partial revert of the aforementioned commit to restore
IPS_CONFIRMED.

[ Upstream commit 73db1b8f2bb6725b7391e85aab41fdf592b3c0c1 ]
(struct nf_conn)->timeout is an interval before the conntrack
confirmed. After confirmed, it becomes a timestamp.
It is observed that timeout of an unconfirmed conntrack:
- Set by calling ctnetlink_change_timeout(). As a result,
`nfct_time_stamp` was wrongly added to `ct->timeout` twice.
- Get by calling ctnetlink_dump_timeout(). As a result,
`nfct_time_stamp` was wrongly subtracted.
Call Trace:

Separate the 2 cases in:
- Setting `ct->timeout` in __nf_ct_set_timeout().
- Getting `ct->timeout` in ctnetlink_dump_timeout().

Update ctnetlink to set up the timeout _after_ the IPS_CONFIRMED flag is
set on, otherwise conntrack creation via ctnetlink breaks.
Note that the problem described in this patch occurs since the
introduction of the nfnetlink_queue conntrack support, select a
sufficiently old Fixes: tag for -stable kernel to pick up this fix.

[ Upstream commit 4f3ed1293feb9502dc254b05802faf1ad3317ac6 ]
ixgbe currently returns `EINVAL` whenever the flowhash it set by ethtool
because the ethtool code in the kernel passes a non-zero value for hfunc
that ixgbe should allow.
When ethtool is called with `ETHTOOL_SRXFHINDIR`,
`ethtool_set_rxfh_indir` will call ixgbe's set_rxfh function
with `ETH_RSS_HASH_NO_CHANGE`. This value should be accepted.
When ethtool is called with `ETHTOOL_SRSSH`, `ethtool_set_rxfh` will
call ixgbe's set_rxfh function with `rxfh.hfunc`, which appears to be
hardcoded in ixgbe to always be `ETH_RSS_HASH_TOP`. This value should
also be accepted.
Before this patch:
$ sudo ethtool -L eth1 combined 10
$ sudo ethtool -X eth1 default
Cannot set RX flow hash configuration: Invalid argument
After this patch:
$ sudo ethtool -L eth1 combined 10
$ sudo ethtool -X eth1 default
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 10 RX ring(s):

[ Upstream commit e85d3d55875f7a1079edfbc4e4e98d6f8aea9ac7 ]
ethtool uses `ETHTOOL_GRXRINGS` to compute how many queues are supported
by RSS. The driver should return the smaller of either:
- The maximum number of RSS queues the device supports, OR
- The number of RX queues configured
Prior to this change, running `ethtool -X $iface default` fails if the
number of queues configured is larger than the number supported by RSS,
even though changing the queue count correctly resets the flowhash to
use all supported queues.
Other drivers (for example, i40e) will succeed but the flow hash will
reset to support the maximum number of queues supported by RSS, even if
that amount is smaller than the configured amount.
Prior to this change:
$ sudo ethtool -L eth1 combined 20
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 20 RX ring(s):
0: 0 1 2 3 4 5 6 7
8: 8 9 10 11 12 13 14 15
16: 0 1 2 3 4 5 6 7
24: 8 9 10 11 12 13 14 15
32: 0 1 2 3 4 5 6 7
...
You can see that the flowhash was correctly set to use the maximum
number of queues supported by the driver (16).
However, asking the NIC to reset to "default" fails:
$ sudo ethtool -X eth1 default
Cannot set RX flow hash configuration: Invalid argument
After this change, the flowhash can be reset to default which will use
all of the available RSS queues (16) or the configured queue count,
whichever is smaller.
Starting with eth1 which has 10 queues and a flowhash distributing to
all 10 queues:
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 10 RX ring(s):
0: 0 1 2 3 4 5 6 7
8: 8 9 0 1 2 3 4 5
16: 6 7 8 9 0 1 2 3
...
Increasing the queue count to 48 resets the flowhash to distribute to 16
queues, as it did before this patch:
$ sudo ethtool -L eth1 combined 48
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 16 RX ring(s):
0: 0 1 2 3 4 5 6 7
8: 8 9 10 11 12 13 14 15
16: 0 1 2 3 4 5 6 7
...
Due to the other bugfix in this series, the flowhash can be set to use
queues 0-5:
$ sudo ethtool -X eth1 equal 5
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 16 RX ring(s):
0: 0 1 2 3 4 0 1 2
8: 3 4 0 1 2 3 4 0
16: 1 2 3 4 0 1 2 3
...
Due to this bugfix, the flowhash can be reset to default and use 16
queues:
$ sudo ethtool -X eth1 default
$ sudo ethtool -x eth1
RX flow hash indirection table for eth1 with 16 RX ring(s):
0: 0 1 2 3 4 5 6 7
8: 8 9 10 11 12 13 14 15
16: 0 1 2 3 4 5 6 7

[ Upstream commit e9fce818fe003b6c527f25517b9ac08eb4661b5d ]
The code already clones post action attributes in
mlx5e_clone_flow_attr_for_post_act(). Creating another copy in
mlx5e_tc_post_act_add() is a erroneous leftover from original
implementation. Instead, assign handle->attribute to post_attr provided by
the caller. Note that cloning the attribute second time is not just
wasteful but also causes issues like second copy not being properly updated
in neigh update code which leads to following use-after-free:

[ Upstream commit 4c8189302567f75099a336b0efcff8291ec86ff4 ]
Source port rewrite (forward to ovs internal port or statck device) isn't
supported in the rule of split action. So there is no indirect table in
split rule. The cited commit destroyes indirect table in split rule. The
indirect table for other rules will be destroyed wrongly. It will cause
traffic loss.
Fix it by removing the destroy function in split rule. And also remove
the destroy function in error flow.

[ Upstream commit 0a6b069cc60d68d33b4f6e7dd7f1adc3ec749766 ]
On representor init rx error flow the flow steering pointer is being
released so mlx5e_attach_netdev() doesn't have a valid fs pointer
in its error flow. Make sure the pointer is nullified when released
and add a check in mlx5e_fs_cleanup() to verify fs is not null
as representor cleanup callback would be called anyway.

[ Upstream commit 72ed5d5624af384eaf74d84915810d54486a75e2 ]
The original behavior introduced by commit c6acd629eec7 ("net/mlx5e: Add
support for devlink-port in non-representors mode") correctly
re-instantiated uplink devlink port and related netdevice during devlink
reload. However with migration to auxiliary devices, this behaviour
changed.
Restore the original behaviour and tear down auxiliary devices
completely during devlink reload.

[ Upstream commit dfad99750c0f83b0242572a573afa2c055f85b36 ]
Use the same timeout for sync reset flow and health recovery flow, since
the former involves driver's recovery from firmware reset, which is
similar to health recovery. Otherwise, in some cases, such as a firmware
upgrade on the DPU, the firmware pre-init bit may not be ready within
current timeout and the driver will abort loading back after reset.

[ Upstream commit 1b540decd03acd736693aabb6cb46c71fca38ae6 ]
On failing to create promisc flow steering table, the pointer is
returned with an error. Nullify it so unloading the driver won't try to
destroy a non existing table.
Failing to create promisc table may happen over BF devices when the ARM
side is going through a firmware tear down. The host side start a
reload flow. While the driver unloads, it tries to remove the promisc
table. Remove WARN in this state as it is a valid error flow.

[ Upstream commit 35226750f7ab9d49140d95bc7d38a2a9b0f4fdfc ]
The system hang because of dsa_tag_8021q_port_setup()->
stmmac_vlan_rx_add_vid().
I found in stmmac_drv_probe() that cailing pm_runtime_put()
disabled the clock.
First, when the kernel is compiled with CONFIG_PM=y,The stmmac's
resume/suspend is active.
Secondly,stmmac as DSA master,the dsa_tag_8021q_port_setup() function
will callback stmmac_vlan_rx_add_vid when DSA dirver starts. However,
The system is hanged for the stmmac_vlan_rx_add_vid() accesses its
registers after stmmac's clock is closed.
I would suggest adding the pm_runtime_resume_and_get() to the
stmmac_vlan_rx_add_vid().This guarantees that resuming clock output
while in use.

This happens since btf->refcount can be 1 at the time of btf_put() and
btf_put() will call btf_free_id() which will try to grab btf_idr_lock
and will dead lock.
Avoid the issue by doing btf_put() without locking.

getsockopt assumptions about permitted optval buffer size. Let's enforce
these assumptions only when non-NULL optval is provided.

The ->cleanup callback needs to be removed, this doesn't work anymore as
the transaction mutex is already released in the ->abort function.
Just do it after a successful validation pass, this either happens
from commit or abort phases where transaction mutex is held.

[ Upstream commit 7041101ff6c3073fd8f2e99920f535b111c929cb ]
if sch_fq is configured with "initial quantum" having values greater than
INT_MAX, the first assignment of "credit" does signed integer overflow to
a very negative value.
In this situation, the syzkaller script provided by Cristoph triggers the
CPU soft-lockup warning even with few sockets. It's not an infinite loop,
but "credit" wasn't probably meant to be minus 2Gb for each new flow.
Capping "initial quantum" to INT_MAX proved to fix the issue.
v2: validation of "initial quantum" is done in fq_policy, instead of open
coding in fq_change() _ suggested by Jakub Kicinski

From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit d913d32cc2707e9cd24fe6fa6d7d470e9c728980 ]
Brad Spencer provided a detailed report [0] that when calling getsockopt()
for AF_NETLINK, some SOL_NETLINK options set only 1 byte even though such
options require at least sizeof(int) as length.
The options return a flag value that fits into 1 byte, but such behaviour
confuses users who do not initialise the variable before calling
getsockopt() and do not strictly check the returned value as char.
Currently, netlink_getsockopt() uses put_user() to copy data to optlen and
optval, but put_user() casts the data based on the pointer, char *optval.
As a result, only 1 byte is set to optval.
To avoid this behaviour, we need to use copy_to_user() or cast optval for
put_user().
Note that this changes the behaviour on big-endian systems, but we document
that the size of optval is int in the man page.
$ man 7 netlink
...
Socket options
To set or get a netlink socket option, call getsockopt(2) to read
or setsockopt(2) to write the option with the option level argument
set to SOL_NETLINK. Unless otherwise noted, optval is a pointer to
an int.

[ Upstream commit d325c34d9e7e38d371c0a299d415e9b07f66a1fb ]
After failing to verify configuration, it returns directly without
releasing link, which may cause memory leak.
Paolo Abeni thinks that the whole code of this driver is quite
"suboptimal" and looks unmainatained since at least ~15y, so he
suggests that we could simply remove the whole driver, please
take it into consideration.
Simon Horman suggests that the fix label should be set to
"Linux-2.6.12-rc2" considering that the problem has existed
since the driver was introduced and the commit above doesn't
seem to exist in net/net-next.

From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 50749f2dd6854a41830996ad302aef2ffaf011d8 ]
syzkaller reported [0] memory leaks of an UDP socket and ZEROCOPY
skbs. We can reproduce the problem with these sequences:
sk = socket(AF_INET, SOCK_DGRAM, 0)
sk.setsockopt(SOL_SOCKET, SO_TIMESTAMPING, SOF_TIMESTAMPING_TX_SOFTWARE)
sk.setsockopt(SOL_SOCKET, SO_ZEROCOPY, 1)
sk.sendto(b'', MSG_ZEROCOPY, ('127.0.0.1', 53))
sk.close()
sendmsg() calls msg_zerocopy_alloc(), which allocates a skb, sets
skb->cb->ubuf.refcnt to 1, and calls sock_hold(). Here, struct
ubuf_info_msgzc indirectly holds a refcnt of the socket. When the
skb is sent, __skb_tstamp_tx() clones it and puts the clone into
the socket's error queue with the TX timestamp.
When the original skb is received locally, skb_copy_ubufs() calls
skb_unclone(), and pskb_expand_head() increments skb->cb->ubuf.refcnt.
This additional count is decremented while freeing the skb, but struct
ubuf_info_msgzc still has a refcnt, so __msg_zerocopy_callback() is
not called.
The last refcnt is not released unless we retrieve the TX timestamped
skb by recvmsg(). Since we clear the error queue in inet_sock_destruct()
after the socket's refcnt reaches 0, there is a circular dependency.
If we close() the socket holding such skbs, we never call sock_put()
and leak the count, sk, and skb.
TCP has the same problem, and commit e0c8bccd40fc ("net: stream:
purge sk_error_queue in sk_stream_kill_queues()") tried to fix it
by calling skb_queue_purge() during close(). However, there is a
small chance that skb queued in a qdisc or device could be put
into the error queue after the skb_queue_purge() call.
In __skb_tstamp_tx(), the cloned skb should not have a reference
to the ubuf to remove the circular dependency, but skb_clone() does
not call skb_copy_ubufs() for zerocopy skb. So, we need to call
skb_orphan_frags_rx() for the cloned skb to call skb_copy_ubufs().

[ Upstream commit 2a587b9ad052e7e92e508aea90c1e2ae433c1908 ]
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP_MMIO" to
"select REGMAP_MMIO", which will also set REGMAP.

[ Upstream commit 215792eda008f6a1e7ed9d77fa20d582d22bb114 ]
Commit 041879b12ddb ("drivers: staging: rtl8192bs: Fix deadlock in
rtw_joinbss_event_prehandle()") besides fixing the deadlock also
modified _rtw_join_timeout_handler() to use spin_[un]lock_irq()
instead of spin_[un]lock_bh().
_rtw_join_timeout_handler() calls rtw_do_join() which takes
pmlmepriv->scanned_queue.lock using spin_[un]lock_bh(). This
spin_unlock_bh() call re-enables softirqs which triggers an oops in
kernel/softirq.c: __local_bh_enable_ip() when it calls
lockdep_assert_irqs_enabled():
[ 244.506087] WARNING: CPU: 2 PID: 0 at kernel/softirq.c:376 __local_bh_enable_ip+0xa6/0x100

This oops is causd by the switch to spin_[un]lock_irq() which disables
the IRQs for the entire duration of _rtw_join_timeout_handler().
Disabling the IRQs is not necessary since all code taking this lock
runs from either user contexts or from softirqs, switch back to
spin_[un]lock_bh() to fix this.

[ Upstream commit 5239a89b06d6b199f133bf0ffea421683187f257 ]
This reverts commit 76d62f24db07f22ccf9bc18ca793c27d4ebef721.
So while priority inversion on the pmsg_lock is an occasional
problem that an rt_mutex would help with, in uses where logging
is writing to pmsg heavily from multiple threads, the pmsg_lock
can be heavily contended.
After this change landed, it was reported that cases where the
mutex locking overhead was commonly adding on the order of 10s
of usecs delay had suddenly jumped to ~msec delay with rtmutex.
It seems the slight differences in the locks under this level
of contention causes the normal mutexes to utilize the spinning
optimizations, while the rtmutexes end up in the sleeping
slowpath (which allows additional threads to pile on trying
to take the lock).
In this case, it devolves to a worse case senerio where the lock
acquisition and scheduling overhead dominates, and each thread
is waiting on the order of ~ms to do ~us of work.
Obviously, having tons of threads all contending on a single
lock for logging is non-optimal, so the proper fix is probably
reworking pstore pmsg to have per-cpu buffers so we don't have
contention.
Additionally, Steven Rostedt has provided some furhter
optimizations for rtmutexes that improves the rtmutex spinning
path, but at least in my testing, I still see the test tripping
into the sleeping path on rtmutexes while utilizing the spinning
path with mutexes.
But in the short term, lets revert the change to the rt_mutex
and go back to normal mutexes to avoid a potentially major
performance regression. And we can work on optimizations to both
rtmutexes and finer-grained locking for pstore pmsg in the
future.

[ Upstream commit 4decf4060ecfee1f7a710999fcd421645ac0c419 ]
Currently we process the suspend interrupt event only if the
device is in configured state. Consider a case where device
is not configured and got suspend interrupt, in that case our
gadget will still use 100mA as composite_suspend didn't happen.
But battery charging specification (BC1.2) expects a downstream
device to draw less than 2.5mA when unconnected OR suspended.
Fix this by removing the condition for processing suspend event,
and thus composite_resume would set vbus draw to 2.

[ Upstream commit c47527cbcc3c50800f34b8c684f29721f75de246 ]
The stm32_usart_transmit_chars() may be called with empty or stopped
transmit queue, and no XON/OFF character pending. This can happen at
the end of transmission, where this last call is used to either handle
the XON/XOFF x_char, or disable TX interrupt if queue is empty or
stopped.
If that occurs, do not assert the RS485 RTS/DE GPIO anymore, as the
GPIO would remain asserted past the end of transmission and that would
block the RS485 bus after the transmission.
Only assert the RS485 RTS/DE GPIO if there is either pending XON/XOFF
x_char, or at least one character in running transmit queue.

[ Upstream commit 15ac1122fd6d4bf408a03e6f23c7ad4f60b22f9e ]
The arbitration of the UART DMA is mishandled for a few
exceptional cases when probing and releasing the driver.
It is possible that the DMA register spaces are not defined in
device tree for an instance of the driver, so attempts to access
the registers in brcmuart_arbitration() would use NULL pointers.
It is also possible for the probe function to return an error
while still holding the UART DMA. This would prevent the UART
DMA from being claimed by an instance that could use it.
These errors are addressed by only releasing the UART DMA if it
is held by this instance (i.e. priv->dma_enabled == 1) and
directing early error paths in probe to this common release_dma
handling.

The pm resume call is supposed to enable two clocks. If the second enable
fails the callback reports failure but doesn't undo the first enable.
So call clk_disable() for the first clock when clk_enable() for the second
one fails.

[ Upstream commit 9448bc1dee65f86c0fe64d9dea8b410af0586886 ]
An early error exit in atmel_qspi_remove() doesn't prevent the device
unbind. So this results in an spi controller with an unbound parent
and unmapped register space (because devm_ioremap_resource() is undone).
So using the remaining spi controller probably results in an oops.
Instead unregister the controller unconditionally and only skip hardware
access and clk disable.
Also add a warning about resume failing and return zero unconditionally.
The latter has the only effect to suppress a less helpful error message by
the spi core.

[ Upstream commit 11951c9e3f364d7ae3b568a0e52c8335d43066b5 ]
Returning early in a platform driver's remove callback is wrong. In this
case the dma resources are not released in the error path. this is never
retried later and so this is a permanent leak. To fix this, only skip
hardware disabling if waking the device fails.

Use kunmap_local() to unmap pages locally mapped with kmap_local_page().
kunmap_local() must be called on the kernel virtual address returned by
kmap_local_page(), differently from how we use kunmap() which instead
expects the mapped page as its argument.
In module_zstd_decompress() we currently map with kmap_local_page() and
unmap with kunmap(). This breaks the code and so it should be fixed.

[ Upstream commit 2b947f8769be8b8181dc795fd292d3e7120f5204 ]
In renesas_usb3_probe, role_work is bound with renesas_usb3_role_work.
renesas_usb3_start will be called to start the work.
If we remove the driver which will call usbhs_remove, there may be
an unfinished work. The possible sequence is as follows:
CPU0 CPU1
renesas_usb3_role_work
renesas_usb3_remove
usb_role_switch_unregister
device_unregister
kfree(sw)
//free usb3->role_sw
usb_role_switch_set_role
//use usb3->role_sw
The usb3->role_sw could be freed under such circumstance and then
used in usb_role_switch_set_role.
This bug was found by static analysis. And note that removing a
driver is a root-only operation, and should never happen in normal
case. But the root user may directly remove the device which
will also trigger the remove function.
Fix it by canceling the work before cleanup in the renesas_usb3_remove.

After commit bbf7d3b1c4f40 ("ASoC: soc-pcm: align BE 'atomicity' with
that of the FE") BE and FE atomicity must match.
In the case of Compress PCM there is a mismatch in atomicity between FE
and BE and we get errors like this:
[ 36.434566] sai1-wm8960-hifi: dpcm_be_connect: FE is atomic but BE
is nonatomic, invalid configuration
[ 36.444278] PCM Deep Buffer: ASoC: can't connect SAI1.OUT
In order to fix this we must inherit the atomicity from DAI link
associated with current PCM Compress FE.

[ Upstream commit 5f5ac460dfe7f4e11f99de9870f240e39189cf72 ]
commit bb38919ec56e ("PCI: imx6: Add support for i.MX6 PCIe controller")
added a fault hook to this driver in the probe function. So it was only
installed if needed.
commit bde4a5a00e76 ("PCI: imx6: Allow probe deferral by reset GPIO")
moved it from probe to driver init which installs the hook unconditionally
as soon as the driver is compiled into a kernel.
When this driver is compiled as a module, the hook is not registered
until after the driver has been matched with a .compatible and
loaded.
commit 415b6185c541 ("PCI: imx6: Fix config read timeout handling")
extended the fault handling code.
commit 2d8ed461dbc9 ("PCI: imx6: Add support for i.MX8MQ")
added some protection for non-ARM architectures, but this does not
protect non-i.MX ARM architectures.
Since fault handlers can be triggered on any architecture for different
reasons, there is no guarantee that they will be triggered only for the
assumed situation, leading to improper error handling (i.MX6-specific
imx6q_pcie_abort_handler) on foreign systems.
I had seen strange L3 imprecise external abort messages several times on
OMAP4 and OMAP5 devices and couldn't make sense of them until I realized
they were related to this unused imx6q driver because I had
CONFIG_PCI_IMX6=y.
Note that CONFIG_PCI_IMX6=y is useful for kernel binaries that are designed
to run on different ARM SoC and be differentiated only by device tree
binaries. So turning off CONFIG_PCI_IMX6 is not a solution.
Therefore we check the compatible in the init function before registering
the fault handler.

[ Upstream commit 39db65a0a17b54915b269d3685f253a4731f344c ]
The driver is able to work fine without relying on a mandatory interrupt
being assigned to the I2C device. This is only needed when making use of
the jack-detect support.
However, the following warning message is always emitted when there is
no such interrupt available:
es8316 0-0011: Failed to get IRQ 0: -22
Do not attempt to request an IRQ if it is not available/valid. This also
ensures the rather misleading message is not displayed anymore.
Also note the IRQ validation relies on commit dab472eb931bc291 ("i2c /
ACPI: Use 0 to indicate that device does not have interrupt assigned").

Returning early in a platform driver's remove callback is wrong. In this
case the dma resources are not released in the error path. this is never
retried later and so this is a permanent leak. To fix this, only skip
hardware disabling if waking the device fails.

[ Upstream commit c20c57d9868d7f9fd1b2904c7801b07e128f6322 ]
CPM has the same problem as QE so for CPM also use the fix added
by commit 0398fb70940e ("spi/spi_mpc8xxx: Fix QE mode Litte Endian"):
CPM mode uses Little Endian so words > 8 bits are byte swapped.
Workaround this by always enforcing wordsize 8 for 16 and 32 bits
words. Unfortunately this will not work for LSB transfers
where wordsize is > 8 bits so disable these for now.
Also limit the workaround to 16 and 32 bits words because it can
only work for multiples of 8-bits.

Example thread interleaving that causes the general protection fault
is as follows:
CPU1 (vmci_host_poll) CPU2 (vmci_host_do_init_context)
----- -----
// Read uninitialized context
context = vmci_host_dev->context;
// Initialize context
vmci_host_dev->context = vmci_ctx_create();
vmci_host_dev->ct_type = VMCIOBJ_CONTEXT;
if (vmci_host_dev->ct_type == VMCIOBJ_CONTEXT) {
// Dereferencing the wrong pointer
poll_wait(..., &context->host_context);
}
In this scenario, vmci_host_poll() reads vmci_host_dev->context first,
and then reads vmci_host_dev->ct_type to check that
vmci_host_dev->context is initialized. However, since these two reads
are not atomically executed, there is a chance of a race condition as
described above.
To fix this race condition, read vmci_host_dev->context after checking
the value of vmci_host_dev->ct_type so that vmci_host_poll() always
reads an initialized context.

[ Upstream commit b19a4266c52de78496fe40f0b37580a3b762e67d ]
The helper generating an OF based modalias (of_device_get_modalias())
works fine, but due to the use of snprintf() internally it needs a
buffer one byte longer than what should be needed just for the entire
string (excluding the '\0'). Most users of this helper are sysfs hooks
providing the modalias string to users. They all provide a PAGE_SIZE
buffer which is way above the number of bytes required to fit the
modalias string and hence do not suffer from this issue.
There is another user though, of_device_request_module(), which is only
called by drivers/usb/common/ulpi.c. This request module function is
faulty, but maybe because in most cases there is an alternative, ULPI
driver users have not noticed it.
In this function, of_device_get_modalias() is called twice. The first
time without buffer just to get the number of bytes required by the
modalias string (excluding the null byte), and a second time, after
buffer allocation, to fill the buffer. The allocation asks for an
additional byte, in order to store the trailing '\0'. However, the
buffer *length* provided to of_device_get_modalias() excludes this extra
byte. The internal use of snprintf() with a length that is exactly the
number of bytes to be written has the effect of using the last available
byte to store a '\0', which then smashes the last character of the
modalias string.
Provide the actual size of the buffer to of_device_get_modalias() to fix
this issue.
Note: the "str[size - 1] = '\0';" line is not really needed as snprintf
will anyway end the string with a null byte, but there is a possibility
that this function might be called on a struct device_node without
compatible, in this case snprintf() would not be executed. So we keep it
just to avoid possible unbounded strings.

[ Upstream commit c441b1e03da6c680a3e12da59c554f454f2ccf5e ]
During EDR recovery, the OS must clear error status of the port that
triggered DPC even if firmware retains control of DPC and AER (see the
implementation note in the PCI Firmware spec r3.3, sec 4.6.12).
Prior to 068c29a248b6 ("PCI/ERR: Clear PCIe Device Status errors only if
OS owns AER"), the port Device Status was cleared in this path:
edr_handle_event
dpc_process_error(dev) # "dev" triggered DPC
pcie_do_recovery(dev, dpc_reset_link)
dpc_reset_link # exit DPC
pcie_clear_device_status(dev) # clear Device Status
After 068c29a248b6, pcie_do_recovery() no longer clears Device Status when
firmware controls AER, so the error bit remains set even after recovery.
Per the "Downstream Port Containment configuration control" bit in the
returned _OSC Control Field (sec 4.5.1), the OS is allowed to clear error
status until it evaluates _OST, so clear Device Status in
edr_handle_event() if the error recovery was successful.

[ Upstream commit 8455cbb25927013b3417ab619dced1c0e87708af ]
Based on num_hid_devices, each sensor device is initialized. If
"no sensors" is initialized, amd_sfh work initialization and scheduling
doesn’t make sense and returns EOPNOTSUPP to stop driver probe. Hence,
add a check for "no sensors" enabled to handle the special case.

[ Upstream commit 7a306e3eabf2b2fd8cffa69b87b32dbf814d79ce ]
If there is no ACPI/DT information, it is assumed that L1 caches
are private and L2 (and higher) caches are shared. A cache is
'shared' between two CPUs if it is accessible from these two
CPUs.
Each CPU owns a representation (i.e. has a dedicated cacheinfo struct)
of the caches it has access to. cache_leaves_are_shared() tries to
identify whether two representations are designating the same actual
cache.
In cache_leaves_are_shared(), if 'this_leaf' is a L2 cache (or higher)
and 'sib_leaf' is a L1 cache, the caches are detected as shared as
only this_leaf's cache level is checked.
This is leads to setting sib_leaf as being shared with another CPU,
which is incorrect as this is a L1 cache.
Check 'sib_leaf->level'. Also update the comment as the function is
called when populating 'shared_cpu_map'.

In a very peculiar case when probing and registering with the secondary
DSI host succeeds, but the OF backlight or DSI attachment fails, the
primary DSI device is automatically cleaned up, but the secondary one
is not, leading to -EEXIST when the driver core tries to handle
-EPROBE_DEFER.
Unregister the DSI1 device manually on failure to prevent that.

[ Upstream commit a5a6dd2624698b6e3045c3a1450874d8c790d5d9 ]
Assignment of NVIDIA Ampere-based GPUs have seen a regression since the
below referenced commit, where the reduced D3hot transition delay appears
to introduce a small window where a D3hot->D0 transition followed by a bus
reset can wedge the device. The entire device is subsequently unavailable,
returning -1 on config space read and is unrecoverable without a host
reset.
This has been observed with RTX A2000 and A5000 GPU and audio functions
assigned to a Windows VM, where shutdown of the VM places the devices in
D3hot prior to vfio-pci performing a bus reset when userspace releases the
devices. The issue has roughly a 2-3% chance of occurring per shutdown.
Restoring the HDA controller d3hot_delay to the effective value before the
below commit has been shown to resolve the issue. NVIDIA confirms this
change should be safe for all of their HDA controllers.

The cadence QSPI driver misbehaves after performing a full system suspend
resume:
...
spi-nor spi0.0: resume() failed
...
This results in a flash connected via OSPI interface after system suspend-
resume to be unusable.
fix these suspend and resume functions.

If CONFIG_DEBUG_INFO_REDUCED is enabled in the kernel configuration, we
will typically not be able to load vmlinux-gdb.py and will fail with:
Traceback (most recent call last):
File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/vmlinux-gdb.py", line 25, in <module>

Rather be left wondering what is happening only to find out that reduced
debug information is the cause, raise an eror. This was not typically a
problem until e3c8d33e0d62 ("scripts/gdb: fix 'lx-dmesg' on 32 bits arch")

[ Upstream commit 31088f6f7906253ef4577f6a9b84e2d42447dba0 ]
typeof is (still) a GNU extension, which means that it cannot be used when
building ISO C (e.g. -std=c99). It should therefore be avoided in uapi
headers in favour of the ISO-friendly __typeof__.
Unfortunately this issue could not be detected by
CONFIG_UAPI_HEADER_TEST=y as the __ALIGN_KERNEL() macro is not expanded in
any uapi header.
This matters from a userspace perspective, not a kernel one. uapi
headers and their contents are expected to be usable in a variety of
situations, and in particular when building ISO C applications (with
-std=c99 or similar).
This particular problem can be reproduced by trying to use the
__ALIGN_KERNEL macro directly in application code, say:
#include <linux/const.h>
int align(int x, int a)
{
return __KERNEL_ALIGN(x, a);
}
and trying to build that with -std=c99.

[ Upstream commit 80f746e2bd0e1da3fdb49a53570e54a1a225faac ]
The Store Queue code allocates a bitmap buffer with the size of
multiple of sizeof(long) in sq_api_init(). While the buffer size
is calculated correctly, the code uses the wrong element size to
allocate the buffer which results in the allocated bitmap buffer
being too small.
Fix this by allocating the buffer with kcalloc() with element size
sizeof(long) instead of kzalloc() whose elements size defaults to
sizeof(char).

Commit ac82b56bda5f ("usb: gadget: tegra-xudc: Add vbus_draw support")
populated the vbus_draw callback for the Tegra XUDC driver. The function
tegra_xudc_gadget_vbus_draw(), that was added by this commit, assumes
that the pointer 'curr_usbphy' has been initialised, which is not always
the case because this is only initialised when the USB role is updated.
Fix this crash, by checking that the 'curr_usbphy' is valid before
dereferencing.

[ Upstream commit d28f4091ea7ec3510fd6a3c6d433234e7a2bef14 ]
When handle qmu transfer irq, it will unlock @mtu->lock before give back
request, if another thread handle disconnect event at the same time, and
try to disable ep, it may lock @mtu->lock and free qmu ring, then qmu
irq hanlder may get a NULL gpd, avoid the KE by checking gpd's value before
handling it.
e.g.
qmu done irq on cpu0 thread running on cpu1
qmu_done_tx()
handle gpd [0]
mtu3_requ_complete() mtu3_gadget_ep_disable()
unlock @mtu->lock
give back request lock @mtu->lock
mtu3_ep_disable()
mtu3_gpd_ring_free()
unlock @mtu->lock
lock @mtu->lock
get next gpd [1]
[1]: goto [0] to handle next gpd, and next gpd may be NULL.

Using this macro makes the code more readable.
It also inits the members of dev_pm_ops in the following manner
without us explicitly needing to:
.suspend = cqspi_suspend, \
.resume = cqspi_resume, \
.freeze = cqspi_suspend, \
.thaw = cqspi_resume, \
.poweroff = cqspi_suspend, \
.restore = cqspi_resume
Also get rid of conditional compilation based on CONFIG_PM_SLEEP because
it introduces build issues with certain configs when CQSPI_DEV_PM_OPS is
just NULL.

[ Upstream commit 3fac2397f562eb669ddc2f45867a253f3fc26184 ]
When loading the driver for rtl8192e, the W_DISABLE# switch is working as
intended. But when the WLAN is turned off in software and then turned on
again the W_DISABLE# does not work anymore. Reason for this is that in
the function _rtl92e_dm_check_rf_ctrl_gpio() the bfirst_after_down is
checked and returned when true. bfirst_after_down is set true when
switching the WLAN off in software. But it is not set to false again
when WLAN is turned on again.
Add bfirst_after_down = false in _rtl92e_sta_up to reset bit and fix
above described bug.

If a driver has all its resources allocated through devm_() APIs and
does not need any other explicit cleanup, it would not require a
remove callback to be defined. Hence, add a check for remove callback
presence before calling it when removing a SPMI driver.

[ Upstream commit 6c0b057cec5eade4c3afec3908821176931a9997 ]
In virtio_net, if we disable napi_tx, when we trigger a tx interrupt,
the vq->event_triggered will be set to true. It is then never reset
until we explicitly call virtqueue_enable_cb_delayed or
virtqueue_enable_cb_prepare.
If we disable the napi_tx, virtqueue_enable_cb* will only be called when
the tx ring is getting relatively empty.
Since event_triggered is true, VRING_AVAIL_F_NO_INTERRUPT or
VRING_PACKED_EVENT_FLAG_DISABLE will not be set. As a result we update
vring_used_event(&vq->split.vring) or vq->packed.vring.driver->off_wrap
every time we call virtqueue_get_buf_ctx. This causes more interrupts.
To summarize:
1) event_triggered was set to true in vring_interrupt()
2) after this nothing will happen in virtqueue_disable_cb() so
VRING_AVAIL_F_NO_INTERRUPT is not set in avail_flags_shadow
3) virtqueue_get_buf_ctx_split() will still think the cb is enabled
and then it will publish a new event index
To fix:
update VRING_AVAIL_F_NO_INTERRUPT or VRING_PACKED_EVENT_FLAG_DISABLE in
the vq when we call virtqueue_disable_cb even when event_triggered is
true.
Tested with iperf:
iperf3 tcp stream:
vm1 -----------------> vm2
vm2 just receives tcp data stream from vm1, and sends acks to vm1,
there are many tx interrupts in vm2.
with the patch applied there are just a few tx interrupts.
v2->v3:
-update the interrupt disable flag even with the event_triggered is set,
-instead of checking whether event_triggered is set in
-virtqueue_get_buf_ctx_{packed/split}, will cause the drivers which have
-not called virtqueue_{enable/disable}_cb to miss notifications.
v3->v4:
-remove change for
-"if (vq->packed.event_flags_shadow != VRING_PACKED_EVENT_FLAG_DISABLE)"
-in virtqueue_disable_cb_packed

Get rid of conditional compilation based on CONFIG_PM_SLEEP because
it may introduce build issues with certain configs where it maybe disabled
This is because if above config is not enabled the suspend-resume
functions are never part of the code but the bcm63xx_spi_pm_ops struct
still inits them to non-existent suspend-resume functions.

When dev_err_probe() is called, 'ret' holds the value of the previous
successful devm_request_irq() call.
'ret' should be assigned with a meaningful value before being used in
dev_err_probe().
While at it, use and return "PTR_ERR(ctrl->clk)" instead of a hard-coded
"-ENOENT" so that -EPROBE_DEFER is handled and propagated correctly.

[ Upstream commit 8a32341cf04ba05974931b4664683c2c9fb84e56 ]
The testcase verifies the setting of different fields in Monitor Mode
Control Register A (MMCRA). In the current code, EV_CODE_EXTRACT macro
is used to extract the "sample" field, which then needs to be further
processed to fetch rand_samp_elig and rand_samp_mode bits. But the
current code is not passing valid sample field to EV_CODE_EXTRACT
macro. Patch addresses this by fixing the input for EV_CODE_EXTRACT.

Unlike PVR_POWER8, etc ...., PVR_7450 represents a full PVR
value and not a family value.
To avoid confusion, do like E500 family and define the relevant
PVR_VER_xxxx values for the 7450 family:
0x8000 ==> 7450
0x8001 ==> 7455
0x8002 ==> 7447
0x8003 ==> 7447A
0x8004 ==> 7448
And use them to detect 7450 family for perf events.

[ Upstream commit 271208ee5e335cb1ad280d22784940daf7ddf820 ]
Using memcpy() isn't safe when buf is identical to rtas_err_buf, which
can happen during boot before slab is up. Full context which may not
be obvious from the diff:
if (altbuf) {
buf = altbuf;
} else {
buf = rtas_err_buf;
if (slab_is_available())
buf = kmalloc(RTAS_ERROR_LOG_MAX, GFP_ATOMIC);
}
if (buf)
memcpy(buf, rtas_err_buf, RTAS_ERROR_LOG_MAX);
This was found by inspection and I'm not aware of it causing problems
in practice. It appears to have been introduced by commit
033ef338b6e0 ("powerpc: Merge rtas.c into arch/powerpc/kernel"); the
old ppc64 version of this code did not have this problem.
Use memmove() instead.

[ Upstream commit 39afe5d6fc59237ff7738bf3ede5a8856822d59d ]
There are scenarios where non-affine wakeups are incorrectly counted as
affine wakeups by schedstats.
When wake_affine_idle() returns prev_cpu which doesn't equal to
nr_cpumask_bits, it will slip through the check: target == nr_cpumask_bits
in wake_affine() and be counted as if target == this_cpu in schedstats.
Replace target == nr_cpumask_bits with target != this_cpu to make sure
affine wakeups are accurately tallied.

[ Upstream commit 15def34e2635ab7e0e96f1bc32e1b69609f14942 ]
commit e050e3f0a71bf ("perf: Fix broken interrupt rate throttling")
introduces a change in throttling threshold judgment. Before this,
compare hwc->interrupts and max_samples_per_tick, then increase
hwc->interrupts by 1, but this commit reverses order of these two
behaviors, causing the semantics of max_samples_per_tick to change.
In literal sense of "max_samples_per_tick", if hwc->interrupts ==
max_samples_per_tick, it should not be throttled, therefore, the judgment
condition should be changed to "hwc->interrupts > max_samples_per_tick".
In fact, this may cause the hardlockup to fail, The minimum value of
max_samples_per_tick may be 1, in this case, the return value of
__perf_event_account_interrupt function is 1.
As a result, nmi_watchdog gets throttled, which would stop PMU (Use x86
architecture as an example, see x86_pmu_handle_irq).

[ Upstream commit e18398e80c73e3cc7d9c3d2e0bc06a4af8f4f1cb ]
Commit 468af56a7bba ("objtool: Support addition to set CFA base") was
added as a preparatory patch for arm64 support, but that support never
came. It triggers a false positive warning on x86, so just revert it
for now.
Fixes the following warning:
vmlinux.o: warning: objtool: cdce925_regmap_i2c_write+0xdb: stack state mismatch: cfa1=4+120 cfa2=5+40

The KASAN shadow region was moved next to the kernel mapping but the
ptdump code was not updated and it appears to break the dump of the kernel
page table, so fix this by moving the KASAN shadow region in ptdump.

[ Upstream commit feffe5bb274dd3442080ef0e4053746091878799 ]
Commit 95158a89dd50 ("sched,rt: Use the full cpumask for balancing")
allows find_lock_lowest_rq() to pick a task with migration disabled.
The purpose of the commit is to push the current running task on the
CPU that has the migrate_disable() task away.
However, there is a race which allows a migrate_disable() task to be
migrated. Consider:
CPU0 CPU1
push_rt_task
check is_migration_disabled(next_task)
task not running and
migration_disabled == 0
find_lock_lowest_rq(next_task, rq);
_double_lock_balance(this_rq, busiest);
raw_spin_rq_unlock(this_rq);
double_rq_lock(this_rq, busiest);
<<wait for busiest rq>>
<wakeup>
task become running
migrate_disable();
<context out>
deactivate_task(rq, next_task, 0);
set_task_cpu(next_task, lowest_rq->cpu);
WARN_ON_ONCE(is_migration_disabled(p));

The variable run is not initialized however it is being accumulated
by the return value from the call to ikm_run_monitor. Fix this by
initializing run to zero at the start of the function.

The write index indicates which event the data is for and accesses a
per-file array. The index is passed by user processes during write()
calls as the first 4 bytes. Ensure that it cannot be negative by
returning -EINVAL to prevent out of bounds accesses.
Update ftrace self-test to ensure this occurs properly.

[ Upstream commit 271bfcfb83a9f77cbae3d6e1a16e3c14132922f0 ]
When seg is equal to MAX_ARRAY, the loop should break, otherwise
it will result in out of range access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

[ Upstream commit 4c85e20b656607897e3bb06ff565822fa4b4de95 ]
All the various MediaTek clock drivers are, in a way or another,
redefining the GATE_MTK() macro with different names: while some
are doing that by actually using GATE_MTK(), others are copying
it entirely (hence, entirely redefining it).
Change all clock drivers to always and consistently use this macro.

Instead of calling clk_prepare_enable() for clocks that shall stay
enabled, use the CLK_IS_CRITICAL flag, which purpose is exactly that.

[ Upstream commit b73a0b80c69de77d8d4942abb37066531c0169b2 ]
There is no need to check 'rdi->qp_dev' for NULL. The field 'qp_dev'
is created in rvt_register_device() which will fail if the 'qp_dev'
allocation fails in rvt_driver_qp_init(). Overwise this pointer
doesn't changed and passed to rvt_qp_exit() by the next step.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

[ Upstream commit 335a42ebb0ca8ee9997a1731aaaae6dcd704c113 ]
The workqueue watchdog prints a warning when there is no progress in
a worker pool. Where the progress means that the pool started processing
a pending work item.
Note that it is perfectly fine to process work items much longer.
The progress should be guaranteed by waking up or creating idle
workers.
show_one_worker_pool() prints state of non-idle worker pool. It shows
a delay since the last pool->watchdog_ts.
The timestamp is updated when a first pending work is queued in
__queue_work(). Also it is updated when a work is dequeued for
processing in worker_thread() and rescuer_thread().
The delay is misleading when there is no pending work item. In this
case it shows how long the last work item is being proceed. Show
zero instead. There is no stall if there is no pending work.

[ Upstream commit 0e6255fa3f649170da6bd1a544680589cfae1131 ]
The VRTC alarm register can be programmed with an amount of seconds
after which the SoC will be woken up by the VRTC timer again. We are
already converting the alarm time from meson_vrtc_set_alarm() to
"seconds since 1970". This means we also need to use "seconds since
1970" for the current time.
This fixes a problem where setting the alarm to one minute in the future
results in the firmware (which handles wakeup) to output (on the serial
console) that the system will be woken up in billions of seconds.
ktime_get_raw_ts64() returns the time since boot, not since 1970. Switch
to ktime_get_real_ts64() to fix the calculation of the alarm time and to
make the SoC wake up at the specified date/time. Also the firmware
(which manages suspend) now prints either 59 or 60 seconds until wakeup
(depending on how long it takes for the system to enter suspend).

'exists' looks like a boolean. This patch replaces it by the
normal name used for the rxe device, 'rxe', which should be a
little less confusing. The second rxe_dbg() message is
incorrect since rxe is known to be NULL and this will cause a
seg fault if this message were ever sent. Replace it by pr_debug
for the moment.

[ Upstream commit bfa434c60157c9793e9b12c9b68ade02aff9f803 ]
Label ATTR_ROOT in ntfs_read_mft() sets is_root = true and
ni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC
and alloc ni->dir.alloc_run. However two states are not always
consistent and can make memory leak.
1) attr_name in ATTR_ROOT does not fit the condition it will set
is_root = true but NI_FLAG_DIR is not set.
2) next attr_name in ATTR_ALLOC fits the condition and alloc
ni->dir.alloc_run
3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees
ni->dir.alloc_run, otherwise it frees ni->file.run
4) because NI_FLAG_DIR is not set in this case, ni->dir.alloc_run is
leaked as kmemleak reported:
unreferenced object 0xffff888003bc5480 (size 64):

If the MFT record of ntfs inode is not a base record, inode->i_op can be
NULL. And a null-ptr-deref may happen:
ntfs_lookup()
dir_search_u() # inode->i_op is set to NULL
d_splice_alias()
__d_add()
d_flags_for_inode() # inode->i_op->get_link null-ptr-deref
Fix this by adding a Check on inode->i_op before calling the
d_splice_alias() function.

If the member struct INDEX_BUFFER *index of struct indx_node is
incorrect, that is, the value of __le32 used is greater than the value
of __le32 total in struct INDEX_HDR. Therefore, OOB read occurs when
memmove is called in indx_insert_into_buffer().
Fix this by adding a check in hdr_find_e().

[ Upstream commit 78b26a335310a097d6b22581b706050db42f196c ]
Remove the tasklet call in rxe_cq.c and also the is_dying in the
cq struct. There is no reason for the rxe driver to defer the call
to the cq completion handler by scheduling a tasklet. rxe_cq_post()
is not called in a hard irq context.
The rxe driver currently is incorrect because the tasklet call is
made without protecting the cq pointer with a reference from having
the underlying memory freed before the deferred routine is called.
Executing the comp_handler inline fixes this problem.

[ Upstream commit baba1315a74d12772d4940a05d58dc03e6ec0635 ]
When the SOC approaches zero, an integer overflows in the columb
counter causing the driver to react poorly. This makes the driver
think it's at (above) the fully charged capacity when in fact it's
zero. It would then write this full capacity to NVRAM which would be
used on boot if the device remained off for less than 5 hours and
not plugged in.
This can be fixed and guarded against by doing the following:
- Changing the type of tmp in rk817_read_or_set_full_charge_on_boot()
to be an int instead of a u32. That way we can account for negative
numbers.
- Guard against negative values for the full charge on boot by setting
the charge to 0 if the system charge reports less than 0.
- Catch scenarios where the battery voltage is below the design
minimum voltage and set the system SOC to 0 at that time and update
the columb counter with a charge level of 0.
- Change the off time value from 5 hours to 30 minutes before we
recalculate the current capacity based on the OCV tables.
These changes allow the driver to operate better at low voltage/low
capacity conditions.

[ Upstream commit eca5cd9474cd26d62f9756f536e2e656d3f62f3a ]
When unregistering MAD agent, srpt module has a non-null check
for 'mad_agent' pointer before invoking ib_unregister_mad_agent().
This check can pass if 'mad_agent' variable holds an error value.
The 'mad_agent' can have an error value for a short window when
srpt_add_one() and srpt_remove_one() is executed simultaneously.
In srpt module, added a valid pointer check for 'sport->mad_agent'
before unregistering MAD agent.
This issue can hit when RoCE driver unregisters ib_device

[ Upstream commit 9fe8fec5e43d5a80f43cbf61aaada1b047a1eb61 ]
hfi1_mmu_rb_remove_unless_exact() did not move mmu_rb_node objects in
mmu_rb_handler->lru_list after getting a cache hit on an mmu_rb_node.
As a result, hfi1_mmu_rb_evict() was not guaranteed to evict truly
least-recently used nodes.
This could be a performance issue for an application when that
application:
- Uses some long-lived buffers frequently.
- Uses a large number of buffers once.
- Hits the mmu_rb_handler cache size or pinned-page limits, forcing
mmu_rb_handler cache entries to be evicted.
In this case, the one-time use buffers cause the long-lived buffer
entries to eventually filter to the end of the LRU list where
hfi1_mmu_rb_evict() will consider evicting a frequently-used long-lived
entry instead of evicting one of the one-time use entries.
Fix this by inserting new mmu_rb_node at the tail of
mmu_rb_handler->lru_list and move mmu_rb_ndoe to the tail of
mmu_rb_handler->lru_list when the mmu_rb_node is a hit in
hfi1_mmu_rb_remove_unless_exact(). Change hfi1_mmu_rb_evict() to evict
from the head of mmu_rb_handler->lru_list instead of the tail.

[ Upstream commit 00cbce5cbf88459cd1aa1d60d0f1df15477df127 ]
hfi1 user SDMA request processing has two bugs that can cause data
corruption for user SDMA requests that have multiple payload iovecs
where an iovec other than the tail iovec does not run up to the page
boundary for the buffer pointed to by that iovec.a
Here are the specific bugs:
1. user_sdma_txadd() does not use struct user_sdma_iovec->iov.iov_len.
Rather, user_sdma_txadd() will add up to PAGE_SIZE bytes from iovec
to the packet, even if some of those bytes are past
iovec->iov.iov_len and are thus not intended to be in the packet.
2. user_sdma_txadd() and user_sdma_send_pkts() fail to advance to the
next iovec in user_sdma_request->iovs when the current iovec
is not PAGE_SIZE and does not contain enough data to complete the
packet. The transmitted packet will contain the wrong data from the
iovec pages.
This has not been an issue with SDMA packets from hfi1 Verbs or PSM2
because they only produce iovecs that end short of PAGE_SIZE as the tail
iovec of an SDMA request.
Fixing these bugs exposes other bugs with the SDMA pin cache
(struct mmu_rb_handler) that get in way of supporting user SDMA requests
with multiple payload iovecs whose buffers do not end at PAGE_SIZE. So
this commit fixes those issues as well.
Here are the mmu_rb_handler bugs that non-PAGE_SIZE-end multi-iovec
payload user SDMA requests can hit:
1. Overlapping memory ranges in mmu_rb_handler will result in duplicate
pinnings.
2. When extending an existing mmu_rb_handler entry (struct mmu_rb_node),
the mmu_rb code (1) removes the existing entry under a lock, (2)
releases that lock, pins the new pages, (3) then reacquires the lock
to insert the extended mmu_rb_node.
If someone else comes in and inserts an overlapping entry between (2)
and (3), insert in (3) will fail.
The failure path code in this case unpins _all_ pages in either the
original mmu_rb_node or the new mmu_rb_node that was inserted between
(2) and (3).
3. In hfi1_mmu_rb_remove_unless_exact(), mmu_rb_node->refcount is
incremented outside of mmu_rb_handler->lock. As a result, mmu_rb_node
could be evicted by another thread that gets mmu_rb_handler->lock and
checks mmu_rb_node->refcount before mmu_rb_node->refcount is
incremented.
4. Related to #2 above, SDMA request submission failure path does not
check mmu_rb_node->refcount before freeing mmu_rb_node object.
If there are other SDMA requests in progress whose iovecs have
pointers to the now-freed mmu_rb_node(s), those pointers to the
now-freed mmu_rb nodes will be dereferenced when those SDMA requests
complete.

From: Jerry Snitselaar <jsnitsel@redhat.com>
[ Upstream commit 8f880d19e6ad645a4b8066d5ff091c980b3231e7 ]
With the addition of the V2 page table support, the domain page size
bitmap needs to be set prior to iommu core setting up direct mappings
for reserved regions. When reserved regions are mapped, if this is not
done, it will be looking at the V1 page size bitmap when determining
the page size to use in iommu_pgsize(). When it gets into the actual
amd mapping code, a check of see if the page size is supported can
fail, because at that point it is checking it against the V2 page size
bitmap which only supports 4K, 2M, and 1G.
Add a check to __iommu_domain_alloc() to not override the
bitmap if it was already set by the iommu ops domain_alloc() code path.

From: Heiko Carstens <hca@linux.ibm.com>
[ Upstream commit e42ac7789df64120d7d3d57433dfc9f37ec0cb99 ]
Commit dfe843dce775 ("s390/checksum: support GENERIC_CSUM, enable it for
KASAN") switched s390 to use the generic checksum functions, so that KASAN
instrumentation also works checksum functions by avoiding architecture
specific inline assemblies.
There is however the problem that the generic csum_partial() function
returns a 32 bit value with a 16 bit folded checksum, while the original
s390 variant does not fold to 16 bit. This in turn causes that the
ipib_checksum in lowcore contains different values depending on kernel
config options.
The ipib_checksum is used by system dumpers to verify if pointers in
lowcore point to valid data. Verification is done by comparing checksum
values. The system dumpers still use 32 bit checksum values which are not
folded, and therefore the checksum verification fails (incorrectly).
Symptom is that reboot after dump does not work anymore when a KASAN
instrumented kernel is dumped.
Fix this by not using the generic checksum implementation. Instead add an
explicit kasan_check_read() so that KASAN knows about the read access from
within the inline assembly.

[ Upstream commit 1a500e0bc97b6cb3c0d9859e81973b8dd07d1b7b ]
On SM8350 platform the PCIe PIPE clocks require additional handling to
function correctly. They are to be switched to the tcxo source before
turning PCIe GDSCs off and should be switched to PHY PIPE source once
they are working. Switch PCIe PHY clocks to use clk_regmap_phy_mux_ops,
which provide support for this dance.

[ Upstream commit a90922fa25370902322e9de6640e58737d459a50 ]
The reservedmem_of_init_fn's are invoked very early at boot before the
memory zones have even been defined. This makes it inappropriate to test
whether the page corresponding to a PFN is in ZONE_HIGHMEM from within
one.
Removing the check allows an ARM 32-bit kernel with SPARSEMEM enabled to
boot properly since otherwise we would be de-referencing an
uninitialized sparsemem map to perform pfn_to_page() check.
The arm64 architecture happens to work (and also has no high memory) but
other 32-bit architectures could also be having similar issues.
While it would be nice to provide early feedback about a reserved DMA
pool residing in highmem, it is not possible to do that until the first
time we try to use it, which is where the check is moved to.

[ Upstream commit 5499d01c029069044a3b3e50501c77b474c96178 ]
For io_tlb_nslabs, the debugfs code reports the correct value for a
specific reserved memory pool. But for io_tlb_used, the value reported
is always for the default pool, not the specific reserved pool. Fix this.

[ Upstream commit 3946fc2a42b18cf0b675121158a2625825ce27b5 ]
Originally is was thought that the tasklet machinery in rxe_task.c would
be used in other applications but that has not happened for years. This
patch replaces the 'void *arg' by struct 'rxe_qp *qp' in the parameters to
the tasklet calls. This change will have no affect on performance but may
make the code a little clearer.

[ Upstream commit 960ebe97e5238565d15063c8f4d1b2108efe2e65 ]
The subroutine __rxe_do_task is not thread safe and it has no way to
guarantee that the tasks, which are designed with the assumption that they
are non-reentrant, are not reentered. All of its uses are non-performance
critical.
This patch replaces calls to __rxe_do_task with calls to
rxe_sched_task. It also removes irrelevant or unneeded if tests.
Instead of calling the task machinery a single call to the tasklet
function (rxe_requester, etc.) is sufficient to draing the queues if task
execution has been disabled or stopped.
Together these changes allow the removal of __rxe_do_task.

[ Upstream commit b2b1ddc457458fecd1c6f385baa9fbda5f0c63ad ]
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like rxe_init_task are not setup until
rxe_qp_init_req().
If an error occurred before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.
If rxe_init_task is not executed, rxe_cleanup_task will not be called.

[ Upstream commit d43b020b0f82c088ef8ff3196ef00575a97d200e ]
relaxed_ordering_read HCA capability is set if both the device supports
relaxed ordering (RO) read and RO is set in PCI config space.
RO in PCI config space can change during runtime. This will change the
value of relaxed_ordering_read HCA capability in FW, but the driver will
not see it since it queries the capabilities only once.
This can lead to the following scenario:
1. RO in PCI config space is enabled.
2. User creates MKey without RO.
3. RO in PCI config space is disabled.
As a result, relaxed_ordering_read HCA capability is turned off in FW
but remains on in driver copy of the capabilities.
4. User requests to reconfig the MKey with RO via UMR.
5. Driver will try to reconfig the MKey with RO read although it
shouldn't (as relaxed_ordering_read HCA capability is really off).
To fix this, check pcie_relaxed_ordering_enabled() before setting RO
read in UMR.

[ Upstream commit 3e358ea8614ddfbc59ca7a3f5dff5dde2b350b2c ]
Commit cited in "fixes" tag added bulk support for flow counters but it
didn't account that's also possible to query a counter using a non-base id
if the counter was allocated as bulk.
When a user performs a query, validate the flow counter id given in the
mailbox is inside the valid range taking bulk value into account.

From: Dai Ngo <dai.ngo@oracle.com>
[ Upstream commit 691d0b782066a6eeeecbfceb7910a8f6184e6105 ]
Currently call_bind_status places a hard limit of 3 to the number of
retries on EACCES error. This limit was done to prevent NLM unlock
requests from being hang forever when the server keeps returning garbage.
However this change causes problem for cases when NLM service takes
longer than 9 seconds to register with the port mapper after a restart.
This patch removes this hard coded limit and let the RPC handles
the retry based on the standard hard/soft task semantics.
Fixes: 0b760113a3a1 ("NLM: Don't hang forever on NLM unlock requests")

[ Upstream commit 812489ac4dd91144a74ce65ecf232252a2e406fb ]
In commit 91993c8c2ed5 ("openrisc: use shadow registers to save regs on
exception") the unhandled exception path was changed to do an early
store of r30 instead of r31. The entry code was not updated and r31 is
not getting stored to pt_regs.
This patch updates the entry handler to store r31 instead of r30. We
also remove some misleading commented out store r30 and r31
instructrions.
I noticed this while working on adding floating point exception
handling, This issue probably would never impact anything since we kill
the process or Oops right away on unhandled exceptions.

Above issue is happens when enable bigalloc and inline data feature. As
commit 131294c35ed6 fixed delayed allocation bug in ext4_clu_mapped for
bigalloc + inline. But it only resolved issue when has inline data, if
inline data has been converted to extent(ext4_da_convert_inline_data_to_extent)
before writepages, there is no EXT4_STATE_MAY_INLINE_DATA flag. However
i_data is still store inline data in this scene. Then will trigger UAF
when find extent.
To resolve above issue, there is need to add judge "ext4_has_inline_data(inode)"
in ext4_clu_mapped().
Fixes: 131294c35ed6 ("ext4: fix delayed allocation bug in ext4_clu_mapped for bigalloc + inline")

From: Geert Uytterhoeven <geert+renesas@glider.be>
[ Upstream commit 0a7a5226e7b177c68800985a19a80c1df9bceff6 ]
According to R-Car V4H Series User’s Manual: Hardware Rev. 0.54, pin
groups 4 and 5 do not use Module Select Registers to configure pin
functions, but use Peripheral Function Select Registers instead.
Hence:
- Remove the non-existent Module Select Registers (MODSEL[45]),
- Add the missing Peripheral Function Select Registers (IPxSR[45]),
- Correct the GPIO / Peripheral Function Select Register definitions
(GPSR]45_*),
- Correct the affected PINMUX definitions.
Fixes: 36611d28f5130d8b ("pinctrl: renesas: r8a779g0: Add missing MODSELx for AVBx")
Fixes: 36fb7b8af55b83e0 ("pinctrl: renesas: r8a779g0: Add missing MODSELx for TSN0")

From: Geert Uytterhoeven <geert+renesas@glider.be>
[ Upstream commit 203734a0419cade9c76016f66e2c7ba354c249b4 ]
According to R-Car V4H Series User’s Manual: Hardware Rev. 0.54, pin
groups 6 and 7 do not use Module Select Registers to configure pin
functions.
Hence:
- Remove the non-existent Module Select Registers (MODSEL[67]),
- Correct the affected PINMUX definitions.
Fixes: 36611d28f5130d8b ("pinctrl: renesas: r8a779g0: Add missing MODSELx for AVBx")
Fixes: ad9bb2fec66262b0 ("pinctrl: renesas: Initial R8A779G0 (R-Car V4H) PFC support")

To: stable; +Cc: Greg Kroah-Hartman, patches, Geert Uytterhoeven, Sasha Levin
From: Geert Uytterhoeven <geert+renesas@glider.be>
[ Upstream commit 9da805344d2a2d27a32cc9271230055d8818e887 ]
According to R-Car V4H Series User’s Manual: Hardware Rev. 0.54, the
ERROROUTC signal is active-low. Hence add the missing "_N" suffix to
the pin function's names.
Resize column 2 of all IPxSR* definitions to accomodate the longer
names.
Fixes: b811062e5fd0343c ("pinctrl: renesas: r8a779g0: Add missing ERROROUTC_A")
Fixes: ad9bb2fec66262b0 ("pinctrl: renesas: Initial R8A779G0 (R-Car V4H) PFC support")

[ Upstream commit a61079efc87888587e463afaed82417b162fbd69 ]
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".

[ Upstream commit c1087c29e96a48e9080377e168d35dcb52fb068b ]
Commit 96f524105b9c ("leds: tca6507: use fwnode API instead of OF")
changed to fwnode API but did not take into account that a missing property
"linux,default-trigger" now seems to return an error and as a side effect
sets value to -1. This seems to be different from of_get_property() which
always returned NULL in any case of error.
Neglecting this side-effect leads to
[ 11.201965] Unable to handle kernel paging request at virtual address ffffffff when read
in the strcmp() of led_trigger_set_default() if there is no led-trigger
defined in the DTS.
I don't know if this was recently introduced somewhere in the fwnode lib
or if the effect was missed in initial testing. Anyways it seems to be a
bug to ignore the error return value of an optional value here in the
driver.

[ Upstream commit b16c310115f2084b8826a35b77ef42bab6786d9f ]
The DISP_PWM controller's default behavior is to always use register
double buffering: all reads/writes are then performed on shadow
registers instead of working registers and this becomes an issue
in case our chosen configuration in Linux is different from the
default (or from the one that was pre-applied by the bootloader).
An example of broken behavior is when the controller is configured
to use shadow registers, but this driver wants to configure it
otherwise: what happens is that the .get_state() callback is called
right after registering the pwmchip and checks whether the PWM is
enabled by reading the DISP_PWM_EN register;
At this point, if shadow registers are enabled but their content
was not committed before booting Linux, we are *not* reading the
current PWM enablement status, leading to the kernel knowing that
the hardware is actually enabled when, in reality, it's not.
The aforementioned issue emerged since this driver was fixed with
commit 0b5ef3429d8f ("pwm: mtk-disp: Fix the parameters calculated
by the enabled flag of disp_pwm") making it to read the enablement
status from the right register.
Configure the controller in the .get_state() callback to avoid
this desync issue and get the backlight properly working again.

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
[ Upstream commit 0a0d1740bd8fd7dafb81fcb102fb5d0b83b1ce73 ]
The existing code copies the hw_params pointer and reuses it later in
.prepare, specifically to re-initialize the ALH DMA channel
information that's lost in suspend-resume cycles.
This is not needed, we can directly access the information from the
substream/rtd - as done for the HDAudio DAIs in
sound/soc/sof/intel/hda-dai.c
In addition, using the saved pointer causes the suspend-resume test
cases to fail on specific platforms, depending on which version of GCC
is used. Péter Ujfalusi and I have spent long hours to root-cause this
problem that was reported by the Intel CI first with 6.2-rc1 and again
v6.3-rc1. In the latter case we were lucky that the problem was 100%
reproducible on local test devices, and found out that adding a
dev_dbg() or adding a call to usleep_range() just before accessing the
saved pointer "fixed" the issue. With errors appearing just by
changing the compiler version or minor changes in the code generated,
clearly we have a memory management Heisenbug.
The root-cause seems to be that the hw_params pointer is not
persistent. The soc-pcm code allocates the hw_params structure on the
stack, and passes it to the BE dailink hw_params and DAIs
hw_params. Saving such a pointer and reusing it later during the
.prepare stage cannot possibly work reliably, it's broken-by-design
since v5.10. It's astonishing that the problem was not seen earlier.
This simple fix will have to be back-ported to -stable, due to changes
to avoid the use of the get/set_dmadata routines this patch will only
apply on kernels older than v6.1.

[ Upstream commit a251994a441ee0a69ba7062c8cd2d08ead3db379 ]
The dw-edma driver stops after processing a DMA request even if a request
remains in the issued queue, which is not the expected behavior. The DMA
engine API requires continuous processing.
Add a trigger to start after one processing finished if there are requests
remain.

[ Upstream commit b7badd752de05312fdb1aeb388480f706d0c087f ]
In the past setting the pin direction called pinctrl_gpio_direction()
which uses a mutex to serialize this. That was changed to set the
direction directly in the pin controller driver, but that lost the
serialization mechanism. Since the direction of multiple pins are in
the same register you can have a race condition, something that was
in fact observed with the cec-gpio driver.
Add a new spinlock to serialize writing to the FSEL registers.

[ Upstream commit 1be1b23696b3d4b0231c694f5e0767b4471d33a9 ]
The I2C_DETECT register is at IO port 0x1a7, which is outside the range
passed to devm_ioport_map() for io_base, and was only working because
there aren't actually any bounds checks for IO port accesses.
Extending the range does not seem like a good solution here, as it would
then conflict with the IO resource assigned to the I2C controller. As
this is just a one-off access during probe, use a simple inb() instead.
While we're at it, drop the unused define TQMX86_REG_I2C_INT_EN.

Also change the size of the range to include 0x19f. While 0x19f is

[ Upstream commit f376c479668557bcc2fd9e9fbc0f53e7819a11cd ]
It seems that this driver was developed based on preliminary documentation.
Report the correct names for all TQMxE39x variants, as they are used by
the released hardware revisions:
- Fix names for TQMxE39C1/C2 board IDs
- Distinguish TQMxE39M and TQMxE39S, which use the same board ID
The TQMxE39M/S are distinguished using the SAUC (Sanctioned Alternate
Uses Configuration) register of the GPIO controller. This also prepares
for the correct handling of the differences between the GPIO controllers
of our COMe and SMARC modules.

[ Upstream commit f0484d2f80a72022b7fac72bcb406392900ef1eb ]
Ocelot chips (VSC7511, VSC7512, VSC7513, VSC7514) don't support bulk read
operations over SPI.
Many SPI buses have hardware that can optimize consecutive reads.
Essentially an address is written to the chip, and if the SPI controller
continues to toggle the clock, subsequent register values are reported.
This can lead to significant optimizations, because the time between
"address is written to the chip" and "chip starts to report data" can often
take a fixed amount of time.
When support for Ocelot chips were added in commit f3e893626abe ("mfd:
ocelot: Add support for the vsc7512 chip via spi") it was believed that
this optimization was supported. However it is not.
Most register transactions with the Ocelot chips are not done in bulk, so
this bug could go unnoticed. The one scenario where bulk register
operations _are_ performed is when polling port statistics counters, which
was added in commit d87b1c08f38a ("net: mscc: ocelot: use bulk reads for
stats").
Things get slightly more complicated here...
A bug was introduced in commit d4c367650704 ("net: mscc: ocelot: keep
ocelot_stat_layout by reg address, not offset") that broke the optimization
of bulk reads. This means that when Ethernet support for the VSC7512 chip
was added in commit 3d7316ac81ac ("net: dsa: ocelot: add external ocelot
switch control") things were actually working "as expected".
The bulk read opmtimization was discovered, and fixed in commit
6acc72a43eac ("net: mscc: ocelot: fix stats region batching") and the
timing optimizations for SPI were noticed. A bulk read went from ~14ms to
~2ms. But this timing improvement came at the cost of every register
reading zero due the fact that bulk reads don't work.
The read timings increase back to 13-14ms, but that's a price worth paying
in order to receive valid data. This is verified in a DSA setup (cpsw-new
switch tied to port 0 on the VSC7512, after having been running overnight)

[ Upstream commit 9b04d99788cf475cbd277f30ec66230ccb7e99f4 ]
The CPR3 power resource on the Toshiba Click Mini toggles a GPIO
which is called SISP (for SIS touchscreen power?) on/off.
This CPR3 power resource is not listed in any _PR? lists, let alone
in a _PR0 list for the SIS0817 touchscreen ACPI device which needs it.
Before commit a1224f34d72a ("ACPI: PM: Check states of power resources
during initialization") this was not an issue because since nothing
referenced the CPR3 power resource its state was always
ACPI_POWER_RESOURCE_STATE_UNKNOWN and power resources with this state
get ignored by acpi_turn_off_unused_power_resources().
This clearly is a bug in the DSDT of this device. Add a DMI quirk
to make acpi_turn_off_unused_power_resources() a no-op on this
model to fix the touchscreen no longer working since kernel 5.16 .
This quirk also causes 2 other power resources to not get turned
off, but the _OFF method on these already was a no-op, so this makes
no difference for the other 2 power resources.
Fixes: a1224f34d72a ("ACPI: PM: Check states of power resources during initialization")

There is need to check snapshot_test and open block device
in different mode, so as to avoid the race condition.
No functional changes intended.

[ Upstream commit 5904de0d735bbb3b4afe9375c5b4f9748f882945 ]
The system refused to do a test_resume because it found that the
swap device has already been taken by someone else. Specifically,
the swsusp_check()->blkdev_get_by_dev(FMODE_EXCL) is supposed to
do this check.
Steps to reproduce:
dd if=/dev/zero of=/swapfile bs=$(cat /proc/meminfo |
awk '/MemTotal/ {print $2}') count=1024 conv=notrunc
mkswap /swapfile
swapon /swapfile
swap-offset /swapfile

This is because when using the swapfile as the hibernation storage,
the block device where the swapfile is located has already been mounted
by the OS distribution(usually mounted as the rootfs). This is not
an issue for normal hibernation, because software_resume()->swsusp_check()
happens before the block device(rootfs) mount. But it is a problem for the
test_resume mode. Because when test_resume happens, the block device has
been mounted already.
Thus remove the FMODE_EXCL for test_resume mode. This would not be a
problem because in test_resume stage, the processes have already been
frozen, and the race condition described in
Commit 39fbef4b0f77 ("PM: hibernate: Get block device exclusively in swsusp_check()")
is unlikely to happen.

Fix afs_getattr() to report the server's idea of the file size of a
directory rather than the local size. The local size may differ as we edit
the local copy to avoid having to redownload it and we may end up with a
differently structured blob of a different size.
However, if the directory is discarded from the pagecache we then download
it again and the user may see the directory file size apparently change.

[ Upstream commit 9ea4eff4b6f4f36546d537a74da44fd3f30903ab ]
afs_read_dir fetches an amount of data that's based on what the inode
size is thought to be. If the file on the server is larger than what
was fetched, the code rechecks i_size and retries. If the local i_size
was not properly updated, this can lead to an endless loop of fetching
i_size from the server and noticing each time that the size is larger on
the server.
If it is known that the remote size is larger than i_size, bump up the
fetch size to that size.

commit 6e3220ba3323a2c24be834aebf5d6e9f89d0993f upstream.
Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.
It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.
I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.

commit d755bd2caeb47fd806e12399fe8b56798fa5d2cc upstream.
Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
(which is the case for PA-RISC), __kunmap_local() calls
kunmap_flush_on_unmap(), which may call the parisc flush functions with
a non-page-aligned address and thus the page might not be fully flushed.
This patch ensures that flush_kernel_dcache_page_asm() and
flush_kernel_dcache_page_asm() will always operate on page-aligned
addresses.

commit 7501f472977df233d039d86c6981e0641708e1ca upstream.
One more Pioneer quirk, this time for DDJ-800, which is quite similar like
other DJ DDJ models but with slightly different EPs or channels.

commit e7477cb97607b373d175a759c8c0270a640ab3f2 upstream.
This patch adds support for the mute LED on the HP Pavilion Aero Laptop
13-be0xxx. The current behavior is that the LED does not turn on at any
time and does not indicate to the user whether the sound is muted.
The solution is to add a PCI quirk to properly recognize and support the
LED on this device.
This change has been tested on the device in question using modified
versions of kernels 6.0.7-6.2.12 on Arch Linux.

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 28a65b49eb53e172d23567005465019658bfdb4d upstream.
According to syzbot's report, mark_buffer_dirty() called from
nilfs_segctor_do_construct() outputs a warning with some patterns after
nilfs2 detects metadata corruption and degrades to read-only mode.
After such read-only degeneration, page cache data may be cleared through
nilfs_clear_dirty_page() which may also clear the uptodate flag for their
buffer heads. However, even after the degeneration, log writes are still
performed by unmount processing etc., which causes mark_buffer_dirty() to
be called for buffer heads without the "uptodate" flag and causes the
warning.
Since any writes should not be done to a read-only file system in the
first place, this fixes the warning in mark_buffer_dirty() by letting
nilfs_segctor_do_construct() abort early if in read-only mode.
This also changes the retry check of nilfs_segctor_write_out() to avoid
unnecessary log write retries if it detects -EROFS that
nilfs_segctor_do_construct() returned.

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit a6a491c048882e7e424d407d32cba0b52d9ef2bf upstream.
If the disk image that nilfs2 mounts is corrupted and a virtual block
address obtained by block lookup for a metadata file is invalid,
nilfs_bmap_lookup_at_level() may return the same internal return code as
-ENOENT, meaning the block does not exist in the metadata file.
This duplication of return codes confuses nilfs_mdt_get_block(), causing
it to read and create a metadata block indefinitely.
In particular, if this happens to the inode metadata file, ifile,
semaphore i_rwsem can be left held, causing task hangs in lock_mount.
Fix this issue by making nilfs_bmap_lookup_at_level() treat virtual block
address translation failures with -ENOENT as metadata corruption instead
of returning the error code.

commit d824ec2a154677f63c56cc71ffe4578274f6e32e upstream.
If the page is pinned, there's no point in trying to reclaim it.
Furthermore if the page is from the page cache we don't want to reclaim
fs-private data from the page because the pinning process may be writing
to the page at any time and reclaiming fs private info on a dirty page can
upset the filesystem (see link below).

commit 3899d94e3831ee07ea6821c032dc297aec80586a upstream.
When we receive a flush command (or "barrier" in DRBD), we currently use
a REQ_OP_FLUSH with the REQ_PREFLUSH flag set.
The correct way to submit a flush bio is by using a REQ_OP_WRITE without
any data, and set the REQ_PREFLUSH flag.
Since commit b4a6bb3a67aa ("block: add a sanity check for non-write
flush/fua bios"), this triggers a warning in the block layer, but this
has been broken for quite some time before that.
So use the correct set of flags to actually make the flush happen.

commit a405c6f0229526160aa3f177f65e20c86fce84c5 upstream.
init_resync() inits mempool and sets conf->have_replacemnt at the beginning
of sync, close_sync() frees the mempool when sync is completed.
After [1] recovery might be skipped and init_resync() is called but
close_sync() is not. null-ptr-deref occurs with r10bio->dev[i].repl_bio.
The following is one way to reproduce the issue.
1) create a array, wait for resync to complete, mddev->recovery_cp is set
to MaxSector.
2) recovery is woken and it is skipped. conf->have_replacement is set to
0 in init_resync(). close_sync() not called.
3) some io errors and rdev A is set to WantReplacement.
4) a new device is added and set to A's replacement.
5) recovery is woken, A have replacement, but conf->have_replacemnt is
0. r10bio->dev[i].repl_bio will not be alloced and null-ptr-deref
occurs.
Fix it by not calling init_resync() if recovery skipped.

commit fc05e06e6098ca2c28f7a10da0e00aeea20fa59e upstream.
Commit 7e55c60acfbb ("md/raid5: Pivot raid5_make_request()") changed the
order in which requests for underlying disks are created. Since for
large sequential IO adding of requests frequently races with md_raid5
thread submitting bios to underlying disks, this results in a change in
IO pattern because intermediate states of new order of request creation
result in more smaller discontiguous requests. For RAID5 on top of three
rotational disks our performance testing revealed this results in
regression in write throughput:
iozone -a -s 131072000 -y 4 -q 8 -i 0 -i 1 -R
before 7e55c60acfbb:
KB reclen write rewrite read reread
131072000 4 493670 525964 524575 513384
131072000 8 540467 532880 512028 513703
after 7e55c60acfbb:
KB reclen write rewrite read reread
131072000 4 421785 456184 531278 509248
131072000 8 459283 456354 528449 543834
To reduce the amount of discontiguous requests we can start generating
requests with the stripe with the lowest chunk offset as that has the
best chance of being adjacent to IO queued previously. This improves the
performance to:
KB reclen write rewrite read reread
131072000 4 497682 506317 518043 514559
131072000 8 514048 501886 506453 504319
restoring big part of the regression.

virt_to_page() on a vmalloc adddress. With CONFIG_DEBUG_VIRTUAL selected
this will be reported explicitly, and with or without CONFIG_DEBUG_VIRTUAL
the kernel will dereference a bogus address:

| Kernel panic - not syncing: Attempted to kill the idle task!
This is because init_vmalloc_pages() erroneously calls virt_to_page() on
a vmalloc address, while virt_to_page() is only valid for addresses in
the linear/direct map. Since init_vmalloc_pages() expects virtual
addresses in the vmalloc range, it must use vmalloc_to_page() rather
than virt_to_page().
We call init_vmalloc_pages() from __kasan_unpoison_vmalloc(), where we
check !is_vmalloc_or_module_addr(), suggesting that we might encounter a
non-vmalloc address. Luckily, this never happens. By design, we only
call __kasan_unpoison_vmalloc() on pointers in the vmalloc area, and I
have verified that we don't violate that expectation. Given that,
is_vmalloc_or_module_addr() must always be true for any legitimate
argument to __kasan_unpoison_vmalloc().
Correct init_vmalloc_pages() to use vmalloc_to_page(), and remove the
redundant and misleading use of is_vmalloc_or_module_addr() in
__kasan_unpoison_vmalloc().

commit 1cd9ceaa5282ff10ea20a7fbadde5a476a1cc99e upstream.
Commit c048b60d39e1 ("mtd: core: provide unique name for nvmem device")
tries to give the nvmem device a unique name, but fails badly if the mtd
device doesn't have a "struct device" associated with it, i.e. if
CONFIG_MTD_PARTITIONED_MASTER is not set. This will result in the name
"(null)-user-otp", which is not unique. It seems the best we can do is
to use the compatible name together with a unique identifier added by
the nvmem subsystem by using NVMEM_DEVID_AUTO.

mtd->dev. Instead use the parent device which is the physical flash
memory.

commit e0489f6e221f5ddee6cb3bd51b992b790c5fa4b9 upstream.
If mtd_otp_nvmem_add() fails, the partitions won't be removed
because there is simply no call to del_mtd_partitions().
Unfortunately, add_mtd_partitions() will print all partitions to
the kernel console. If mtd_otp_nvmem_add() returns -EPROBE_DEFER
this would print the partitions multiple times to the kernel
console. Instead move mtd_otp_nvmem_add() to the beginning of the
function.

The bug was obswerved while reading code. There are not many users of
addr_mode_nbytes. Anyway, we should update the flash's current address
mode when changing the address mode, fix it. We don't care for now about
the set_4byte_addr_mode(nor, false) from spi_nor_restore(), as it is
used at driver remove and shutdown.

commit 81c18e08a609706c5c2887f267135fa0dece4119 upstream.
If the unit address is appended to node name of memory-region,
then adding rproc carveouts fails as node name and unit-address
both are passed as carveout name (i.e. vdev0vring0@xxxxxxxx). However,
only node name is expected by remoteproc framework. This patch moves
memory-region node parsing from driver probe to prepare and
only passes node-name and not unit-address

The reason for this is that on certain arm64 configuration since
e35123d83ee3 ("arm64: lto: Strengthen READ_ONCE() to acquire when
CONFIG_LTO=y"), READ_ONCE() may be promoted to a full atomic acquire
instruction which cannot be used on unaligned addresses.
Fix it by avoiding READ_ONCE() in read_instrumented_memory(), and simply
forcing the compiler to do the required access by casting to the
appropriate volatile type. In terms of generated code this currently
only affects architectures that do not use the default READ_ONCE()
implementation.
The only downside is that we are not guaranteed atomicity of the access
itself, although on most architectures a plain load up to machine word
size should still be atomic (a fact the default READ_ONCE() still relies
on itself).

commit 63cfd210034c772fad047afa13dd5a4664b0a72e upstream.
There are two pointers in struct xfrm_dev_offload, *dev, *real_dev.
The *dev points whether bonding interface or real interface, if
bonding IPsec offload is used, it points bonding interface; if not,
it points real interface. And *real_dev always points real interface.
So nfp should always use real_dev instead of dev.
Prior to this change the system becomes unresponsive when offloading
IPsec for a device which is a lower device to a bonding device.
Fixes: 859a497fe80c ("nfp: implement xfrm callbacks and expose ipsec offload feature to upper layer")

commit d46e04ccd40457a0119b76e11ab64a2ad403e138 upstream.
Always run the entire init sequence (rtl8xxxu_init_device()) for
RTL8192EU. It's what the vendor driver does too.
This fixes a bug where the device is unable to connect after
rebooting:
wlp3s0f3u2: send auth to ... (try 1/3)
wlp3s0f3u2: send auth to ... (try 2/3)
wlp3s0f3u2: send auth to ... (try 3/3)
wlp3s0f3u2: authentication with ... timed out
Rebooting leaves the device powered on (partially? at least the
firmware is still running), but not really in a working state.

From: Sascha Hauer <s.hauer@pengutronix.de>
commit 14705f969d98187a1cc2682e0c9bd2e230b8098f upstream.
On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the
vendor driver suggests that the field width of rfe_option is 5 bit,
so rfe_option should be masked with 0x1f.
Without this the rfe_option comparisons with 2 further down the
driver evaluate as false when they should really evaluate as true.
The effect is that 2G channels do not work.
rfe_option is also used as an array index into rtw8821c_rfe_defs[].
rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support,
likely because rfe_option reads as 0x22. As this now becomes 0x2,
rtw8821c_rfe_defs[34] is no longer used and can be removed.
Note that this might not be the whole truth. In the vendor driver
there are indeed places where the unmasked rfe_option value is used.
However, the driver has several places where rfe_option is tested
with the pattern if (rfe_option == 2 || rfe_option == 0x22) or
if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5)
has no influence on the code path taken. We therefore mask BIT(5)
out from rfe_option entirely until this assumption is proved wrong
by some chip variant we do not know yet.

To fix this, follow Jonas' suggestion to switch the order of these
functions and move register netdev to be the last step of PCI probe.
Also, correct the error handling of rtw89_core_register_hw().

commit 7455b7007b9e93bcc2bc9c1c6c73a228e3152069 upstream.
Similar to commit 1c11289b34ab ("peci: cpu: Fix use-after-free in
adev_release()"), the auxiliary device is not torn down in the correct
order. If auxiliary_device_add() fails, the release callback will be
called twice, resulting in a UAF. Due to timing, the auxdev code in this
driver "took inspiration" from the aforementioned commit, and thus its
bugs too!
Moving auxiliary_device_uninit() to the unregister callback instead
avoids the issue.

commit 933bf364e152cd60902cf9585c2ba310d593e69f upstream.
clk_cifout is derived from clk_cifout_src through an integer divider
limited to 32. clk_cifout_src is a child of either cpll, gpll or npll
without any possibility of a divider of any sort. The default clock
parent is cpll.
Let's allow clk_cifout to ask its parent clk_cifout_src to reparent in
order to find the real closest possible rate for clk_cifout and not one
derived from cpll only.

From: Qu Wenruo <wqu@suse.com>
commit 604e6681e114d05a2e384c4d1e8ef81918037ef5 upstream.
Since the introduction of scrub interface, the only flag that we support
is BTRFS_SCRUB_READONLY. Thus there is no sanity checks, if there are
some undefined flags passed in, we just ignore them.
This is problematic if we want to introduce new scrub flags, as we have
no way to determine if such flags are supported.
Address the problem by introducing a check for the flags, and if
unsupported flags are set, return -EOPNOTSUPP to inform the user space.
This check should be backported for all supported kernels before any new
scrub flags are introduced.

From: Lorenzo Stoakes <lstoakes@gmail.com>
commit 00ca0f2e86bf40b016a646e6323a8941a09cf106 upstream.
The refactoring in commit f4e9e0e69468 ("mm/mempolicy: fix use-after-free
of VMA iterator") introduces a subtle bug which arises when attempting to
apply a new NUMA policy across a range of VMAs in mbind_range().
The refactoring passes a **prev pointer to keep track of the previous VMA
in order to reduce duplication, and in all but one case it keeps this
correctly updated.
The bug arises when a VMA within the specified range has an equivalent
policy as determined by mpol_equal() - which unlike other cases, does not
update prev.
This can result in a situation where, later in the iteration, a VMA is
found whose policy does need to change. At this point, vma_merge() is
invoked with prev pointing to a VMA which is before the previous VMA.
Since vma_merge() discovers the curr VMA by looking for the one
immediately after prev, it will now be in a situation where this VMA is
incorrect and the merge will not proceed correctly.
This is checked in the VM_WARN_ON() invariant case with end >
curr->vm_end, which, if a merge is possible, results in a warning (if
CONFIG_DEBUG_VM is specified).
I note that vma_merge() performs these invariant checks only after
merge_prev/merge_next are checked, which is debatable as it hides this
issue if no merge is possible even though a buggy situation has arisen.
The solution is simply to update the prev pointer even when policies are
equal.
This caused a bug to arise in the 6.2.y stable tree, and this patch
resolves this bug.

commit c82729e06644f4e087f5ff0f91b8fb15e03b8890 upstream.
While using the vdpa device with vIOMMU enabled
in the guest VM, when the vdpa device bind to vfio-pci and run testpmd
then system will fail to unmap.
The test process is
Load guest VM --> attach to virtio driver--> bind to vfio-pci driver
So the mapping process is
1)batched mode map to normal MR
2)batched mode unmapped the normal MR
3)unmapped all the memory
4)mapped to iommu MR
This error happened in step 3). The iotlb was freed in step 2)
and the function vhost_vdpa_process_iotlb_msg will return fail
Which causes failure.
To fix this, we will not remove the AS while the iotlb->nmaps is 0.
This will free in the vhost_vdpa_clean

commit e8c5d45f82ce0c238a4817739892fe8897a3dcc3 upstream.
In verity_end_io(), if bi_status is not BLK_STS_OK, it can be return
directly. But if FEC configured, it is desired to correct the data page
through verity_verify_io. And the return value will be converted to
blk_status and passed to verity_finish_io().
BTW, when a bit is set in v->validated_blocks, verity_verify_io() skips
verification regardless of I/O error for the corresponding bio. In this
case, the I/O error could not be returned properly, and as a result,
there is a problem that abnormal data could be read for the
corresponding block.
To fix this problem, when an I/O error occurs, do not skip verification
even if the bit related is set in v->validated_blocks.
Fixes: 843f38d382b1 ("dm verity: add 'check_at_most_once' option to only validate hashes once")

commit 3d32aaa7e66d5c1479a3c31d6c2c5d45dd0d3b89 upstream.
syzkaller found the following problematic rwsem locking (with write
lock already held):
down_read+0x9d/0x450 kernel/locking/rwsem.c:1509
dm_get_inactive_table+0x2b/0xc0 drivers/md/dm-ioctl.c:773
__dev_status+0x4fd/0x7c0 drivers/md/dm-ioctl.c:844
table_clear+0x197/0x280 drivers/md/dm-ioctl.c:1537
In table_clear, it first acquires a write lock
https://elixir.bootlin.com/linux/v6.2/source/drivers/md/dm-ioctl.c#L1520
down_write(&_hash_lock);
Then before the lock is released at L1539, there is a path shown above:
table_clear -> __dev_status -> dm_get_inactive_table -> down_read
https://elixir.bootlin.com/linux/v6.2/source/drivers/md/dm-ioctl.c#L773
down_read(&_hash_lock);
It tries to acquire the same read lock again, resulting in the deadlock
problem.
Fix this by moving table_clear()'s __dev_status() call to after its
up_write(&_hash_lock);

commit 38d11da522aacaa05898c734a1cec86f1e611129 upstream.
Commit fa247089de99 ("dm: requeue IO if mapping table not yet available")
added a detection of whether the mapping table is available in the IO
submission process. If the mapping table is unavailable, it returns
BLK_STS_RESOURCE and requeues the IO.
This can lead to the following deadlock problem:
dm create mount
ioctl(DM_DEV_CREATE_CMD)
ioctl(DM_TABLE_LOAD_CMD)
do_mount
vfs_get_tree
ext4_get_tree
get_tree_bdev
sget_fc
alloc_super
// got &s->s_umount
down_write_nested(&s->s_umount, ...);
ext4_fill_super
ext4_load_super
ext4_read_bh
submit_bio
// submit and wait io end
ioctl(DM_DEV_SUSPEND_CMD)
dev_suspend
do_resume
dm_suspend
__dm_suspend
lock_fs
freeze_bdev
get_active_super
grab_super
// wait for &s->s_umount
down_write(&s->s_umount);
dm_swap_table
__bind
// set md->map(can't get here)
IO will be continuously requeued while holding the lock since mapping
table is NULL. At the same time, mapping table won't be set since the
lock is not available.
Like request-based DM, bio-based DM also has the same problem.
It's not proper to just abort IO if the mapping table not available.
So clear DM_SKIP_LOCKFS_FLAG when the mapping table is NULL, this
allows the DM table to be loaded and the IO submitted upon resume.

commit 5f2779dfa7b8cc7dfd4a1b6586d86e0d193266f3 upstream.
The behavior of 'enum' types has changed in gcc-13, so now the
UNBUSY_THR_PCT constant is interpreted as a 64-bit number because
it is defined as part of the same enum definition as some other
constants that do not fit within a 32-bit integer. This in turn
leads to some inefficient code on 32-bit architectures as well
as a link error:
arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: block/blk-iocost.o: in function `ioc_timer_fn':
blk-iocost.c:(.text+0x68e8): undefined reference to `__aeabi_uldivmod'
arm-linux-gnueabi-ld: blk-iocost.c:(.text+0x6908): undefined reference to `__aeabi_uldivmod'
Split the enum definition to keep the 64-bit timing constants in
a separate enum type from those constants that can clearly fit
within a smaller type.

commit 90c49fce1c43e1cc152695e20363ff5087897c09 upstream.
TCP_Server_Info::hostname may be updated once or many times during
reconnect, so protect its access outside reconnect path as well and
then prevent any potential use-after-free bugs.

From: Paulo Alcantara <pc@manguebit.com>
commit 8e3554150d6c80a84b3cb046615d1a0e943811dc upstream.
When matching DFS connections, we can't rely on the values set in
cifs_sb_info::prepath and cifs_tcon::tree_name as they might change
during DFS failover. The DFS referrals related to a specific DFS tcon
are already matched earlier in match_server(), therefore we can safely
skip those checks altogether as the connection is guaranteed to be
unique for the DFS tcon.
Besides, when creating or finding an SMB session, make sure to also
refcount any DFS root session related to it (cifs_ses::dfs_root_ses),
so if a new DFS mount ends up reusing the connection from the old
mount while there was an umount(2) still in progress (e.g. umount(2)
-> cifs_umount() -> reconnect -> cifs_put_tcon()), the connection
could potentially be put right after the umount(2) finished.
Patch has minor update to include fix for unused variable issue
noted by the kernel test robot

commit ee20d7c6100752eaf2409d783f4f1449c29ea33d upstream.
Protect access of TCP_Server_Info::hostname when building the ipc tree
name as it might get freed in cifsd thread and thus causing an
use-after-free bug in __tree_connect_dfs_target(). Also, while at it,
update status of IPC tcon on success and then avoid any extra tree
connects.

commit d31137619776f9c173a46a79bc7733a2b106061f upstream.
tb_port_is_clx_enabled() generates a valid warning with gcc-13:
drivers/thunderbolt/switch.c:1286:6: error: conflicting types for 'tb_port_is_clx_enabled' due to enum/integer mismatch; have 'bool(struct tb_port *, unsigned int)' ...
drivers/thunderbolt/tb.h:1050:6: note: previous declaration of 'tb_port_is_clx_enabled' with type 'bool(struct tb_port *, enum tb_clx)' ...
I.e. the type of the 2nd parameter of tb_port_is_clx_enabled() in the
declaration is unsigned int, while the definition spells enum tb_clx.
Synchronize them to the former as the parameter is in fact a mask of the
enum values.

commit 1f9f33ccf0320be21703d9195dd2b36a1c9a07cb upstream.
kallsyms is not completely in address order.
In find_entire_kern_cb(), calculate the kernel end from the maximum
address not the last symbol.
Example:
Before:
$ sudo cat /proc/kallsyms | grep ' [twTw] ' | tail -1
ffffffffc00b8bd0 t bpf_prog_6deef7357e7b4530 [bpf]
$ sudo cat /proc/kallsyms | grep ' [twTw] ' | sort | tail -1
ffffffffc15e0cc0 t iwl_mvm_exit [iwlmvm]
$ perf.d093603a05aa record -v --kcore -e intel_pt// --filter 'filter *' -- uname |& grep filter
Address filter: filter 0xffffffff93200000/0x2ceba000
After:
$ perf.8fb0f7a01f8e record -v --kcore -e intel_pt// --filter 'filter *' -- uname |& grep filter
Address filter: filter 0xffffffff93200000/0x2e3e2000
Fixes: 1b36c03e356936d6 ("perf record: Add support for using symbols in address filters")

From: Adrian Hunter <adrian.hunter@intel.com>
commit 430635a0ef1ce958b7b4311f172694ece2c692b8 upstream.
After a standalone CBR (not associated with TSC), update the cycles
reference timestamp and reset the cycle count, so that CYC timestamps
are calculated relative to that point with the new frequency.
Fixes: cc33618619cefc6d ("perf tools: Add Intel PT support for decoding CYC packets")

commit 5d968af27a166e055bdd5f832f095d809eadb992 upstream.
Remove the i40e_stat_str() function which prints the string
representation of the i40e_status error code. With upcoming changes
moving away from i40e_status, there will be no need for this function

Cc: Greg Kroah-Hartman, patches, Jan Sokolowski, Tony Nguyen,

From: Jan Sokolowski <jan.sokolowski@intel.com>
commit 5180ff1364bc26c031b54a68a80aa90ce0028b70 upstream.
To prepare for removal of i40e_status, change the variables
from i40e_status to int. This eases the transition when values
are changed to return standard int error codes over enum i40e_status.
As such changes often also change variable orders, a cleanup
is also applied here to make variables conform to RCT and
some lines are also reformatted where applicable.

From: Thomas Gleixner <tglx@linutronix.de>
commit 0af462f19e635ad522f28981238334620881badc upstream.
The recent fix to ensure atomicity of lookup and allocation inadvertently
broke the pool refill mechanism.
Prior to that change debug_objects_activate() and debug_objecs_assert_init()
invoked debug_objecs_init() to set up the tracking object for statically
initialized objects. That's not longer the case and debug_objecs_init() is
now the only place which does pool refills.
Depending on the number of statically initialized objects this can be
enough to actually deplete the pool, which was observed by Ido via a
debugobjects OOM warning.
Restore the old behaviour by adding explicit refill opportunities to
debug_objects_activate() and debug_objecs_assert_init().
Fixes: 63a759694eed ("debugobject: Prevent init race with static objects")

This breaks the build on RISC-V.
Seems to be messing around happening on the same patch in 6.1 w/ a fixup
patch, but sounds like the fixup didn't apply properly either:
https://lore.kernel.org/stable/2023050845-pancreas-postage-5769@gregkh/
The fixup would be needed here too, provided it (:
Cheers,
Conor.
