5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Escande <nico.escande@gmail.com>
[ Upstream commit b7d7f11a291830fdf69d3301075dd0fb347ced84 ]
The hwmp code use objects of type mesh_preq_queue, added to a list in
ieee80211_if_mesh, to keep track of mpath we need to resolve. If the mpath
gets deleted, ex mesh interface is removed, the entries in that list will
never get cleaned. Fix this by flushing all corresponding items of the
preq_queue in mesh_path_flush_pending().
This should take care of KASAN reports like this:

------------------
From: Remi Pommarel <repk@triplefau.lt>
[ Upstream commit 44c06bbde6443de206b30f513100b5670b23fc5e ]
The ieee80211_sta_ps_deliver_wakeup() function takes sta->ps_lock to
synchronizes with ieee80211_tx_h_unicast_ps_buf() which is called from
softirq context. However using only spin_lock() to get sta->ps_lock in
ieee80211_sta_ps_deliver_wakeup() does not prevent softirq to execute
on this same CPU, to run ieee80211_tx_h_unicast_ps_buf() and try to
take this same lock ending in deadlock. Below is an example of rcu stall
that arises in such situation.

This happens because STA has time to disconnect and reconnect before
batadv_v_elp_throughput_metric_update() delayed work gets scheduled. In
this situation, ath10k_sta_state() can be in the middle of resetting
arsta data when the work queue get chance to be scheduled and ends up
accessing it. Locking wiphy prevents that.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lin Ma <linma@zju.edu.cn>
[ Upstream commit ab904521f4de52fef4f179d2dfc1877645ef5f5c ]
The commit 9bb7e0f24e7e ("cfg80211: add peer measurement with FTM
initiator API") defines four attributes NL80211_PMSR_FTM_REQ_ATTR_
{NUM_BURSTS_EXP}/{BURST_PERIOD}/{BURST_DURATION}/{FTMS_PER_BURST} in
following ways.
static const struct nla_policy
nl80211_pmsr_ftm_req_attr_policy[NL80211_PMSR_FTM_REQ_ATTR_MAX + 1] = {
...
[NL80211_PMSR_FTM_REQ_ATTR_NUM_BURSTS_EXP] =
NLA_POLICY_MAX(NLA_U8, 15),
[NL80211_PMSR_FTM_REQ_ATTR_BURST_PERIOD] = { .type = NLA_U16 },
[NL80211_PMSR_FTM_REQ_ATTR_BURST_DURATION] =
NLA_POLICY_MAX(NLA_U8, 15),
[NL80211_PMSR_FTM_REQ_ATTR_FTMS_PER_BURST] =
NLA_POLICY_MAX(NLA_U8, 31),
...
};
That is, those attributes are expected to be NLA_U8 and NLA_U16 types.
However, the consumers of these attributes in `pmsr_parse_ftm` blindly
all use `nla_get_u32`, which is incorrect and causes functionality issues
on little-endian platforms. Hence, fix them with the correct `nla_get_u8`
and `nla_get_u16` functions.

From: Lingbo Kong <quic_lingbok@quicinc.com>
[ Upstream commit a26d8dc5227f449a54518a8b40733a54c6600a8b ]
Currently, the way of parsing Spatial Reuse Parameter Set element is
incorrect and some members of struct ieee80211_he_obss_pd are not assigned.
To address this issue, it must be parsed in the order of the elements of
Spatial Reuse Parameter Set defined in the IEEE Std 802.11ax specification.
The diagram of the Spatial Reuse Parameter Set element (IEEE Std 802.11ax
-2021-9.4.2.252).

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Delevoryas <peter@pjd.dev>
[ Upstream commit c797ce168930ce3d62a9b7fc4d7040963ee6a01e ]
Background:
1. CONFIG_NCSI_OEM_CMD_KEEP_PHY
If this is enabled, we send an extra OEM Intel command in the probe
sequence immediately after discovering a channel (e.g. after "Clear
Initial State").
2. CONFIG_NCSI_OEM_CMD_GET_MAC
If this is enabled, we send one of 3 OEM "Get MAC Address" commands from
Broadcom, Mellanox (Nvidida), and Intel in the *configuration* sequence
for a channel.
3. mellanox,multi-host (or mlx,multi-host)
Introduced by this patch:
https://lore.kernel.org/all/20200108234341.2590674-1-vijaykhemka@fb.com/
Which was actually originally from cosmo.chou@quantatw.com:
https://github.com/facebook/openbmc-linux/commit/9f132a10ec48db84613519258cd8a317fb9c8f1b
Cosmo claimed that the Nvidia ConnectX-4 and ConnectX-6 NIC's don't
respond to Get Version ID, et. al in the probe sequence unless you send
the Set MC Affinity command first.
Problem Statement:
We've been using a combination of #ifdef code blocks and IS_ENABLED()
conditions to conditionally send these OEM commands.
It makes adding any new code around these commands hard to understand.
Solution:
In this patch, I just want to remove the conditionally compiled blocks
of code, and always use IS_ENABLED(...) to do dynamic control flow.
I don't think the small amount of code this adds to non-users of the OEM
Kconfigs is a big deal.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: DelphineCCChiu <delphine_cc_chiu@wiwynn.com>
[ Upstream commit e85e271dec0270982afed84f70dc37703fcc1d52 ]
Currently NCSI driver will send several NCSI commands back to back without
waiting the response of previous NCSI command or timeout in some state
when NIC have multi channel. This operation against the single thread
manner defined by NCSI SPEC(section 6.3.2.3 in DSP0222_1.1.1)
According to NCSI SPEC(section 6.2.13.1 in DSP0222_1.1.1), we should probe
one channel at a time by sending NCSI commands (Clear initial state, Get
version ID, Get capabilities...), than repeat this steps until the max
number of channels which we got from NCSI command (Get capabilities) has
been probed.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit c0b98ac1cc104f48763cdb27b1e9ac25fd81fc90 ]
As explained in commit 1378817486d6 ("tipc: block BH
before using dst_cache"), net/core/dst_cache.c
helpers need to be called with BH disabled.
Disabling preemption in seg6_output_core() is not good enough,
because seg6_output_core() is called from process context,
lwtunnel_output() only uses rcu_read_lock().
We might be interrupted by a softirq, re-enter seg6_output_core()
and corrupt dst_cache data structures.
Fix the race by using local_bh_disable() instead of
preempt_disable().
Apply a similar change in seg6_input_core().
Fixes: fa79581ea66c ("ipv6: sr: fix several BUGs when preemption is enabled")
Fixes: 6c8702c60b88 ("ipv6: sr: add support for SRH encapsulation and injection with lwtunnels")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Subbaraya Sundeep <sbhatta@marvell.com>
[ Upstream commit 8b0f7410942cdc420c4557eda02bfcdf60ccec17 ]
PF mcam entries has to be at low priority always so that VF
can install longest prefix match rules at higher priority.
This was taken care currently but when priority allocation
wrt reference entry is requested then entries are allocated
from mid-zone instead of low priority zone. Fix this and
always allocate entries from low priority zone for PFs.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Borkmann <daniel@iogearbox.net>
[ Upstream commit 1cd4bc987abb2823836cbb8f887026011ccddc8a ]
Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address")
has recently been added to vxlan mainly in the context of source
address snooping/learning so that when it is enabled, an entry in the
FDB is not being created for an invalid address for the corresponding
tunnel endpoint.
Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in
that it passed through whichever macs were set in the L2 header. It
turns out that this change in behavior breaks setups, for example,
Cilium with netkit in L3 mode for Pods as well as tunnel mode has been
passing before the change in f58f45c1e5b9 for both vxlan and geneve.
After mentioned change it is only passing for geneve as in case of
vxlan packets are dropped due to vxlan_set_mac() returning false as
source and destination macs are zero which for E/W traffic via tunnel
is totally fine.
Fix it by only opting into the is_valid_ether_addr() check in
vxlan_set_mac() when in fact source address snooping/learning is
actually enabled in vxlan. This is done by moving the check into
vxlan_snoop(). With this change, the Cilium connectivity test suite
passes again for both tunnel flavors.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason Xing <kernelxing@tencent.com>
[ Upstream commit a46d0ea5c94205f40ecf912d1bb7806a8a64704f ]
According to RFC 1213, we should also take CLOSE-WAIT sockets into
consideration:
"tcpCurrEstab OBJECT-TYPE
...
The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT."
After this, CurrEstab counter will display the total number of
ESTABLISHED and CLOSE-WAIT sockets.
The logic of counting
When we increment the counter?
a) if we change the state to ESTABLISHED.
b) if we change the state from SYN-RECEIVED to CLOSE-WAIT.
When we decrement the counter?
a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT,
say, on the client side, changing from ESTABLISHED to FIN-WAIT-1.
b) if the socket leaves CLOSE-WAIT, say, on the server side, changing
from CLOSE-WAIT to LAST-ACK.
Please note: there are two chances that old state of socket can be changed
to CLOSE-WAIT in tcp_fin(). One is SYN-RECV, the other is ESTABLISHED.
So we have to take care of the former case.

taprio_parse_mqprio_opt() must validate it, or userspace
can inject arbitrary data to the kernel, the second time
taprio_change() is called.
First call (with valid attributes) sets dev->num_tc

Second call (with arbitrary mqprio attributes)
returns early from taprio_parse_mqprio_opt()

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 26bfb8b57063f52b867f9b6c8d1742fcb5bd656c ]
When a SOCK_DGRAM socket connect()s to another socket, the both sockets'
sk->sk_state are changed to TCP_ESTABLISHED so that we can register them
to BPF SOCKMAP.
When the socket disconnects from the peer by connect(AF_UNSPEC), the state
is set back to TCP_CLOSE.
Then, the peer's state is also set to TCP_CLOSE, but the update is done
locklessly and unconditionally.
Let's say socket A connect()ed to B, B connect()ed to C, and A disconnects
from B.
After the first two connect()s, all three sockets' sk->sk_state are
TCP_ESTABLISHED:
$ ss -xa
Netid State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess
u_dgr ESTAB 0 0 @A 641 * 642
u_dgr ESTAB 0 0 @B 642 * 643
u_dgr ESTAB 0 0 @C 643 * 0
And after the disconnect, B's state is TCP_CLOSE even though it's still
connected to C and C's state is TCP_ESTABLISHED.
$ ss -xa
Netid State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess
u_dgr UNCONN 0 0 @A 641 * 0
u_dgr UNCONN 0 0 @B 642 * 643

In this case, we cannot register B to SOCKMAP.
So, when a socket disconnects from the peer, we should not set TCP_CLOSE to
the peer if the peer is connected to yet another socket, and this must be
done under unix_state_lock().
Note that we use WRITE_ONCE() for sk->sk_state as there are many lockless
readers. These data-races will be fixed in the following patches.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 942238f9735a4a4ebf8274b218d9a910158941d1 ]
sk->sk_state is changed under unix_state_lock(), but it's read locklessly
in many places.
This patch adds WRITE_ONCE() on the writer side.
We will add READ_ONCE() to the lockless readers in the following patches.
Fixes: 83301b5367a9 ("af_unix: Set TCP_ESTABLISHED for datagram sockets too")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 3a0f38eb285c8c2eead4b3230c7ac2983707599d ]
ioctl(SIOCINQ) calls unix_inq_len() that checks sk->sk_state first
and returns -EINVAL if it's TCP_LISTEN.
Then, for SOCK_STREAM sockets, unix_inq_len() returns the number of
bytes in recvq.
However, unix_inq_len() does not hold unix_state_lock(), and the
concurrent listen() might change the state after checking sk->sk_state.
If the race occurs, 0 is returned for the listener, instead of -EINVAL,
because the length of skb with embryo is 0.
We could hold unix_state_lock() in unix_inq_len(), but it's overkill
given the result is true for pre-listen() TCP_CLOSE state.
So, let's use READ_ONCE() for sk->sk_state in unix_inq_len().

------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit eb0718fb3e97ad0d6f4529b810103451c90adf94 ]
unix_poll() and unix_dgram_poll() read sk->sk_state locklessly and
calls unix_writable() which also reads sk->sk_state without holding
unix_state_lock().
Let's use READ_ONCE() in unix_poll() and unix_dgram_poll() and pass
it to unix_writable().
While at it, we remove TCP_SYN_SENT check in unix_dgram_poll() as
that state does not exist for AF_UNIX socket since the code was added.

From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit a9bf9c7dc6a5899c01cb8f6e773a66315a5cd4b7 ]
As small optimisation, unix_stream_connect() prefetches the client's
sk->sk_state without unix_state_lock() and checks if it's TCP_CLOSE.
Later, sk->sk_state is checked again under unix_state_lock().
Let's use READ_ONCE() for the first check and TCP_CLOSE directly for
the second check.

From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ Upstream commit 45d872f0e65593176d880ec148f41ad7c02e40a7 ]
Once sk->sk_state is changed to TCP_LISTEN, it never changes.
unix_accept() takes advantage of this characteristics; it does not
hold the listener's unix_state_lock() and only acquires recvq lock
to pop one skb.
It means unix_state_lock() does not prevent the queue length from
changing in unix_stream_connect().
Thus, we need to use unix_recvq_full_lockless() to avoid data-race.
Now we remove unix_recvq_full() as no one uses it.
Note that we can remove READ_ONCE() for sk->sk_max_ack_backlog in
unix_recvq_full_lockless() because of the following reasons:
(1) For SOCK_DGRAM, it is a written-once field in unix_create1()
(2) For SOCK_STREAM and SOCK_SEQPACKET, it is changed under the
listener's unix_state_lock() in unix_listen(), and we hold
the lock in unix_stream_connect()

[ Upstream commit 83690b82d228b3570565ebd0b41873933238b97f ]
If the socket type is SOCK_STREAM or SOCK_SEQPACKET, unix_release_sock()
checks the length of the peer socket's recvq under unix_state_lock().
However, unix_stream_read_generic() calls skb_unlink() after releasing
the lock. Also, for SOCK_SEQPACKET, __skb_try_recv_datagram() unlinks
skb without unix_state_lock().
Thues, unix_state_lock() does not protect qlen.
Let's use skb_queue_empty_lockless() in unix_release_sock().

We can dump the socket queue length via UNIX_DIAG by specifying
UDIAG_SHOW_RQLEN.
If sk->sk_state is TCP_LISTEN, we return the recv queue length,
but here we do not hold recvq lock.

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit b01e1c030770ff3b4fe37fc7cc6bca03f594133f ]
syzbot found a race in __fib6_drop_pcpu_from() [1]
If compiler reads more than once (*ppcpu_rt),
second read could read NULL, if another cpu clears
the value in rt6_get_pcpu_route().
Add a READ_ONCE() to prevent this race.
Also add rcu_read_lock()/rcu_read_unlock() because
we rely on RCU protection while dereferencing pcpu_rt.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Keeping <john@metanate.com>
[ Upstream commit b566d38857fcb6777f25b674b90a831eec0817a2 ]
Commit fb1f16d74e26 ("usb: gadget: f_fs: change ep->status safe in
ffs_epfile_io()") added a new ffs_io_data::status field to fix lifetime
issues in synchronous requests.
While there are no similar lifetime issues for asynchronous requests
(the separate ep member in ffs_io_data avoids them) using the status
field means the USB request can be freed earlier and that there is more

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wesley Cheng <quic_wcheng@quicinc.com>
[ Upstream commit 24729b307eefcd7c476065cd7351c1a018082c19 ]
FFS based applications can utilize the aio_cancel() callback to dequeue
pending USB requests submitted to the UDC. There is a scenario where the
FFS application issues an AIO cancel call, while the UDC is handling a
soft disconnect. For a DWC3 based implementation, the callstack looks
like the following:
DWC3 Gadget FFS Application
dwc3_gadget_soft_disconnect() ...
--> dwc3_stop_active_transfers()
--> dwc3_gadget_giveback(-ESHUTDOWN)
--> ffs_epfile_async_io_complete() ffs_aio_cancel()
--> usb_ep_free_request() --> usb_ep_dequeue()
There is currently no locking implemented between the AIO completion
handler and AIO cancel, so the issue occurs if the completion routine is
running in parallel to an AIO cancel call coming from the FFS application.
As the completion call frees the USB request (io_data->req) the FFS
application is also referencing it for the usb_ep_dequeue() call. This can
lead to accessing a stale/hanging pointer.
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")
relocated the usb_ep_free_request() into ffs_epfile_async_io_complete().
However, in order to properly implement locking to mitigate this issue, the
spinlock can't be added to ffs_epfile_async_io_complete(), as
usb_ep_dequeue() (if successfully dequeuing a USB request) will call the
function driver's completion handler in the same context. Hence, leading
into a deadlock.
Fix this issue by moving the usb_ep_free_request() back to
ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req
to NULL after freeing it within the ffs->eps_lock. This resolves the race
condition above, as the ffs_aio_cancel() routine will not continue
attempting to dequeue a request that has already been freed, or the
ffs_user_copy_work() not freeing the USB request until the AIO cancel is
done referencing it.
This fix depends on
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status
consistently")
Fixes: 2e4c7553cd6f ("usb: gadget: f_fs: add aio support")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 6b8cffdc4a31e4a72f75ecd1bc13fbf0dafee390 ]
On some designs the chip is not properly reset when powered up at boot or
after a suspend/resume cycle.
Use the sw-reset feature to ensure that the chip is in a clean state
after probe() / resume() and in the case of resume() restore the settings
(scale, trigger-enabled).

Theoretically rare corner case where ceil(Y) results in rounding
up to an integer. If this happens, the 1 should be carried over to
the X value.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexey Kodanev <aleksei.kodanev@bell-sw.com>
[ Upstream commit f8e12e770e8049917f82387033b3cf44bc43b915 ]
pipe_ctx pointer cannot be NULL when getting the address of
an element of the pipe_ctx array. Moreover, the MAX_PIPES is
defined as 6, so pipe_ctx is not NULL after the loop either.
Detected using the static analysis tool - Svace.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hersen Wu <hersenxs.wu@amd.com>
[ Upstream commit 892b41b16f6163e6556545835abba668fcab4eea ]
[Why] DSC debugfs, such as dp_dsc_clock_en_read,
use aconnector->dc_link to find pipe_ctx for display.
Displays connected to MST hub share the same dc_link.
DSC instance is from pipe_ctx. This causes incorrect
DSC instance for display connected to MST hub.
[How] Add aconnector->sink check to find pipe_ctx.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
[ Upstream commit c1426d392aebc51da4944d950d89e483e43f6f14 ]
pvpanic-mmio.c and pvpanic-pci.c share a lot of code.
Refactor it into pvpanic.c where it doesn't have to be kept in sync
manually and where the core logic can be understood more easily.
No functional change.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
[ Upstream commit ee59be35d7a8be7fcaa2d61fb89734ab5c25e4ee ]
In __pci_register_driver(), the pci core overwrites the dev_groups field of
the embedded struct device_driver with the dev_groups from the outer
struct pci_driver unconditionally.
Set dev_groups in the pci_driver to make sure it is used.
This was broken since the introduction of pvpanic-pci.
Fixes: db3a4f0abefd ("misc/pvpanic: add PCI driver")

Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>
Fixes: ded13b9cfd59 ("PCI: Add support for dev_groups to struct pci_driver")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
[ Upstream commit 13244cccc2b61ec715f0ac583d3037497004d4a5 ]
Like skb_pull but returns the original data pointer before pulling the
data after performing a check against sbk->len.
This allows to change code that does "struct foo *p = (void *)skb->data;"
which is hard to audit and error prone, to:
p = skb_pull_data(skb, sizeof(*p));
if (!p)
return;
Which is both safer and cleaner.

From: Luca Weiss <luca.weiss@fairphone.com>
[ Upstream commit f904feefe60c28b6852d5625adc4a2c39426a2d9 ]
Add support for the Bluetooth chip codenamed APACHE which is part of
WCN3988.
The firmware for this chip has a slightly different naming scheme
compared to most others. For ROM Version 0x0200 we need to use
apbtfw10.tlv + apnv10.bin and for ROM version 0x201 apbtfw11.tlv +
apnv11.bin

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tim Jiang <quic_tjiang@quicinc.com>
[ Upstream commit a7f8dedb4be2cc930a29af24427b885405ecd15d ]
This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.
Changes in v2
- optimize the function qca_generate_hsp_nvm_name
- remove redundant debug code for function qca_read_fw_board_id

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hugo Villeneuve <hvilleneuve@dimonoff.com>
[ Upstream commit 8492bd91aa055907c67ef04f2b56f6dadd1f44bf ]
When using a high speed clock with a low baud rate, the 4x prescaler is
automatically selected if required. In that case, sc16is7xx_set_baud()
properly configures the chip registers, but returns an incorrect baud
rate by not taking into account the prescaler value. This incorrect baud
rate is then fed to uart_update_timeout().
For example, with an input clock of 80MHz, and a selected baud rate of 50,
sc16is7xx_set_baud() will return 200 instead of 50.
Fix this by first changing the prescaler variable to hold the selected
prescaler value instead of the MCR bitfield. Then properly take into
account the selected prescaler value in the return value computation.
Also add better documentation about the divisor value computation.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Zijlstra <peterz@infradead.org>
[ Upstream commit aebfd12521d9c7d0b502cf6d06314cfbcdccfe3b ]
Currently a lot of ftrace code assumes __fentry__ is at sym+0. However
with Intel IBT enabled the first instruction of a function will most
likely be ENDBR.
Change ftrace_location() to not only return the __fentry__ location
when called for the __fentry__ location, but also when called for the
sym+0 location.
Then audit/update all callsites of this function to consistently use
these new semantics.

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

From: Zheng Yejian <zhengyejian1@huawei.com>
[ Upstream commit e60b613df8b6253def41215402f72986fee3fc8d ]
KASAN reports a bug:
BUG: KASAN: use-after-free in ftrace_location+0x90/0x120
Read of size 8 at addr ffff888141d40010 by task insmod/424

do_syscall_64+0x68/0x140
entry_SYSCALL_64_after_hwframe+0x71/0x79
The root cause is that, in lookup_rec(), ftrace record of some address
is being searched in ftrace pages of some module, but those ftrace pages
at the same time is being freed in ftrace_release_mod() as the
corresponding module is being deleted:
CPU1 | CPU2
register_kprobes() { | delete_module() {
check_kprobe_address_safe() { |
arch_check_ftrace_location() { |
ftrace_location() { |
lookup_rec() // USE! | ftrace_release_mod() // Free!
To fix this issue:
1. Hold rcu lock as accessing ftrace pages in ftrace_location_range();
2. Use ftrace_location_range() instead of lookup_rec() in
ftrace_location();
3. Call synchronize_rcu() before freeing any ftrace pages both in
ftrace_process_locs()/ftrace_release_mod()/ftrace_free_mem().

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yangtao Li <frank.li@vivo.com>
[ Upstream commit bc1711e8332da03648d8fe1950189237e66313af ]
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.

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
[ Upstream commit 55c421b364482b61c4c45313a535e61ed5ae4ea3 ]
Using __exit for the remove function results in the remove callback being
discarded with CONFIG_MMC_DAVINCI=y. When such a device gets unbound (e.g.
using sysfs or hotplug), the driver is just removed without the cleanup
being performed. This results in resource leaks. Fix it by compiling in the
remove callback unconditionally.
This also fixes a W=1 modpost warning:

From: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
[ Upstream commit 373c612d72461ddaea223592df31e62c934aae61 ]
Add fwnode APIs for finding and getting I2C adapters, which will be
used by the SFP code. These are passed the fwnode corresponding to
the adapter, and return the I2C adapter. It is the responsibility of
the caller to find the appropriate fwnode.
We keep the DT and ACPI interfaces, but where appropriate, recode them
to use the fwnode interfaces internally.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hamish Martin <hamish.martin@alliedtelesis.co.nz>
[ Upstream commit 3f858bbf04dbac934ac279aaee05d49eb9910051 ]
There is an issue with ACPI overlay table removal specifically related
to I2C multiplexers.
Consider an ACPI SSDT Overlay that defines a PCA9548 I2C mux on an
existing I2C bus. When this table is loaded we see the creation of a
device for the overall PCA9548 chip and 8 further devices - one
i2c_adapter each for the mux channels. These are all bound to their
ACPI equivalents via an eventual invocation of acpi_bind_one().
When we unload the SSDT overlay we run into the problem. The ACPI
devices are deleted as normal via acpi_device_del_work_fn() and the
acpi_device_del_list.
However, the following warning and stack trace is output as the
deletion does not go smoothly:

...
repeated 7 more times, 1 for each channel of the mux
...
The issue is that the binding of the ACPI devices to their peer I2C
adapters is not correctly cleaned up. Digging deeper into the issue we
see that the deletion order is such that the ACPI devices matching the
mux channel i2c adapters are deleted first during the SSDT overlay
removal. For each of the channels we see a call to i2c_acpi_notify()
with ACPI_RECONFIG_DEVICE_REMOVE but, because these devices are not
actually i2c_clients, nothing is done for them.
Later on, after each of the mux channels has been dealt with, we come
to delete the i2c_client representing the PCA9548 device. This is the
call stack we see above, whereby the kernel cleans up the i2c_client
including destruction of the mux and its channel adapters. At this
point we do attempt to unbind from the ACPI peers but those peers no
longer exist and so we hit the kernfs errors.
The fix is to augment i2c_acpi_notify() to handle i2c_adapters. But,
given that the life cycle of the adapters is linked to the i2c_client,
instead of deleting the i2c_adapters during the i2c_acpi_notify(), we
just trigger unbinding of the ACPI device from the adapter device, and
allow the clean up of the adapter to continue in the way it always has.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Hildenbrand <david@redhat.com>
[ Upstream commit e16faf26780fc0c8dd693ea9ee8420a7706cb2f5 ]
Patch series "mm: enforce pageblock_order < MAX_ORDER".
Having pageblock_order >= MAX_ORDER seems to be able to happen in corner
cases and some parts of the kernel are not prepared for it.
For example, Aneesh has shown [1] that such kernels can be compiled on
ppc64 with 64k base pages by setting FORCE_MAX_ZONEORDER=8, which will
run into a WARN_ON_ONCE(order >= MAX_ORDER) in comapction code right
during boot.
We can get pageblock_order >= MAX_ORDER when the default hugetlb size is
bigger than the maximum allocation granularity of the buddy, in which
case we are no longer talking about huge pages but instead gigantic
pages.
Having pageblock_order >= MAX_ORDER can only make alloc_contig_range()
of such gigantic pages more likely to succeed.
Reliable use of gigantic pages either requires boot time allcoation or
CMA, no need to overcomplicate some places in the kernel to optimize for
corner cases that are broken in other areas of the kernel.
This patch (of 2):
Let's enforce pageblock_order < MAX_ORDER and simplify.
Especially patch #1 can be regarded a cleanup before:
[PATCH v5 0/6] Use pageblock_order for cma and alloc_contig_range
alignment. [2]

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frank van der Linden <fvdl@google.com>
[ Upstream commit b174f139bdc8aaaf72f5b67ad1bd512c4868a87e ]
cma_init_reserved_mem uses IS_ALIGNED to check if the size represented by
one bit in the cma allocation bitmask is aligned with
CMA_MIN_ALIGNMENT_BYTES (pageblock size).
However, this is too strict, as this will fail if order_per_bit >
pageblock_order, which is a valid configuration.
We could check IS_ALIGNED both ways, but since both numbers are powers of
two, no check is needed at all.

------------------
From: Dev Jain <dev.jain@arm.com>
[ Upstream commit 9ad665ef55eaad1ead1406a58a34f615a7c18b5e ]
Currently, the test tries to set nr_hugepages to zero, but that is not
actually done because the file offset is not reset after read(). Fix that
using lseek().

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@kernel.org>
[ Upstream commit f3b7568c49420d2dcd251032c9ca1e069ec8a6c9 ]
Every test result report in the compaction test prints a distinct log
messae, and some of the reports print a name that varies at runtime. This
causes problems for automation since a lot of automation software uses the
printed string as the name of the test, if the name varies from run to run
and from pass to fail then the automation software can't identify that a
test changed result or that the same tests are being run.
Refactor the logging to use a consistent name when printing the result of
the test, printing the existing messages as diagnostic information instead
so they are still available for people trying to interpret the results.

I'm not convinced that this is a good stable candidate, it will change
the output people are seeing in their test environment which might be an
undesirable change.

Did it change the output in a breaking way in the other stable trees and
normal releases that happened with this commit in it?

Yes, it'd affect other releases - I didn't notice it going into other
stables (I tend to review the AUTOSEL stuff a lot more carefully than
things you send out since you normally only pick things that are Cc
stable but AUTOSEL has some wild stuff). The output tended to be stable
for a given test setup so it's likely that if you're just looking for
the same test results in a stable release you'd see these tests getting
renamed on you.

This is here as a dependency of another change, let me see if I can

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dev Jain <dev.jain@arm.com>
[ Upstream commit d4202e66a4b1fe6968f17f9f09bbc30d08f028a1 ]
Patch series "Fixes for compaction_test", v2.
The compaction_test memory selftest introduces fragmentation in memory
and then tries to allocate as many hugepages as possible. This series
addresses some problems.
On Aarch64, if nr_hugepages == 0, then the test trivially succeeds since
compaction_index becomes 0, which is less than 3, due to no division by
zero exception being raised. We fix that by checking for division by
zero.
Secondly, correctly set the number of hugepages to zero before trying
to set a large number of them.
Now, consider a situation in which, at the start of the test, a non-zero
number of hugepages have been already set (while running the entire
selftests/mm suite, or manually by the admin). The test operates on 80%
of memory to avoid OOM-killer invocation, and because some memory is
already blocked by hugepages, it would increase the chance of OOM-killing.
Also, since mem_free used in check_compaction() is the value before we
set nr_hugepages to zero, the chance that the compaction_index will
be small is very high if the preset nr_hugepages was high, leading to a
bogus test success.
This patch (of 3):
Currently, if at runtime we are not able to allocate a huge page, the test
will trivially pass on Aarch64 due to no exception being raised on
division by zero while computing compaction_index. Fix that by checking
for nr_hugepages == 0. Anyways, in general, avoid a division by zero by
exiting the program beforehand. While at it, fix a typo, and handle the
case where the number of hugepages may overflow an integer.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit fb33eb2ef0d88e75564983ef057b44c5b7e4fded ]
Qgroup extent records are created when delayed ref heads are created and
then released after accounting extents at btrfs_qgroup_account_extents(),
called during the transaction commit path.
If a transaction is aborted we free the qgroup records by calling
btrfs_qgroup_destroy_extent_records() at btrfs_destroy_delayed_refs(),
unless we don't have delayed references. We are incorrectly assuming
that no delayed references means we don't have qgroup extents records.
We can currently have no delayed references because we ran them all
during a transaction commit and the transaction was aborted after that
due to some error in the commit path.
So fix this by ensuring we btrfs_qgroup_destroy_extent_records() at
btrfs_destroy_delayed_refs() even if we don't have any delayed references.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox (Oracle) <willy@infradead.org>
[ Upstream commit 09a46acb3697e50548bb265afa1d79163659dd85 ]
In prepartion for switching from kmap() to kmap_local(), return the kmap
address from nilfs_get_page() instead of having the caller look up
page_address().

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
[ Upstream commit 7373a51e7998b508af7136530f3a997b286ce81c ]
The error handling in nilfs_empty_dir() when a directory folio/page read
fails is incorrect, as in the old ext2 implementation, and if the
folio/page cannot be read or nilfs_check_folio() fails, it will falsely
determine the directory as empty and corrupt the file system.
In addition, since nilfs_empty_dir() does not immediately return on a
failed folio/page read, but continues to loop, this can cause a long loop
with I/O if i_size of the directory's inode is also corrupted, causing the
log writer thread to wait and hang, as reported by syzbot.
Fix these issues by making nilfs_empty_dir() immediately return a false
value (0) if it fails to get a directory folio/page.

From: Alan Stern <stern@rowland.harvard.edu>
commit 22f00812862564b314784167a89f27b444f82a46 upstream.
The syzbot fuzzer found that the interrupt-URB completion callback in
the cdc-wdm driver was taking too long, and the driver's immediate
resubmission of interrupt URBs with -EPROTO status combined with the
dummy-hcd emulation to cause a CPU lockup:
cdc_wdm 1-1:1.0: nonzero urb status received: -71
cdc_wdm 1-1:1.0: wdm_int_callback - 0 bytes

Testing showed that the problem did not occur if the two error
messages -- the first two lines above -- were removed; apparently adding
material to the kernel log takes a surprisingly large amount of time.
In any case, the best approach for preventing these lockups and to
avoid spamming the log with thousands of error messages per second is
to ratelimit the two dev_err() calls. Therefore we replace them with
dev_err_ratelimited().

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
commit 7c55b78818cfb732680c4a72ab270cc2d2ee3d0f upstream.
When an xattr size is not what is expected, it is printed out to the
kernel log in hex format as a form of debugging. But when that xattr
size is bigger than the expected size, printing it out can cause an
access off the end of the buffer.
Fix this all up by properly restricting the size of the debug hex dump
in the kernel log.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Nyman <mathias.nyman@linux.intel.com>
commit f0260589b439e2637ad54a2b25f00a516ef28a57 upstream.
The transferred length is set incorrectly for cancelled bulk
transfer TDs in case the bulk transfer ring stops on the last transfer
block with a 'Stop - Length Invalid' completion code.
length essentially ends up being set to the requested length:
urb->actual_length = urb->transfer_buffer_length
Length for 'Stop - Length Invalid' cases should be the sum of all
TRB transfer block lengths up to the one the ring stopped on,
_excluding_ the one stopped on.
Fix this by always summing up TRB lengths for 'Stop - Length Invalid'
bulk cases.
This issue was discovered by Alan Stern while debugging
https://bugzilla.kernel.org/show_bug.cgi?id=218890, but does not
solve that bug. Issue is older than 4.10 kernel but fix won't apply
to those due to major reworks in that area.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hector Martin <marcan@marcan.st>
commit 5ceac4402f5d975e5a01c806438eb4e554771577 upstream.
When multiple streams are in use, multiple TDs might be in flight when
an endpoint is stopped. We need to issue a Set TR Dequeue Pointer for
each, to ensure everything is reset properly and the caches cleared.
Change the logic so that any N>1 TDs found active for different streams
are deferred until after the first one is processed, calling
xhci_invalidate_cancelled_tds() again from xhci_handle_cmd_set_deq() to
queue another command until we are done with all of them. Also change
the error/"should never happen" paths to ensure we at least clear any
affected TDs, even if we can't issue a command to clear the hardware
cache, and complain loudly with an xhci_warn() if this ever happens.
This problem case dates back to commit e9df17eb1408 ("USB: xhci: Correct
assumptions about number of rings per endpoint.") early on in the XHCI
driver's life, when stream support was first added.
It was then identified but not fixed nor made into a warning in commit
674f8438c121 ("xhci: split handling halted endpoints into two steps"),
which added a FIXME comment for the problem case (without materially
changing the behavior as far as I can tell, though the new logic made
the problem more obvious).
Then later, in commit 94f339147fc3 ("xhci: Fix failure to give back some
cached cancelled URBs."), it was acknowledged again.
[Mathias: commit 94f339147fc3 ("xhci: Fix failure to give back some cached
cancelled URBs.") was a targeted regression fix to the previously mentioned
patch. Users reported issues with usb stuck after unmounting/disconnecting
UAS devices. This rolled back the TD clearing of multiple streams to its
original state.]
Apparently the commit author was aware of the problem (yet still chose
to submit it): It was still mentioned as a FIXME, an xhci_dbg() was
added to log the problem condition, and the remaining issue was mentioned
in the commit description. The choice of making the log type xhci_dbg()
for what is, at this point, a completely unhandled and known broken
condition is puzzling and unfortunate, as it guarantees that no actual
users would see the log in production, thereby making it nigh
undebuggable (indeed, even if you turn on DEBUG, the message doesn't
really hint at there being a problem at all).
It took me *months* of random xHC crashes to finally find a reliable
repro and be able to do a deep dive debug session, which could all have
been avoided had this unhandled, broken condition been actually reported
with a warning, as it should have been as a bug intentionally left in
unfixed (never mind that it shouldn't have been left in at all).
> Another fix to solve clearing the caches of all stream rings with
> cancelled TDs is needed, but not as urgent.
3 years after that statement and 14 years after the original bug was
introduced, I think it's finally time to fix it. And maybe next time
let's not leave bugs unfixed (that are actually worse than the original
bug), and let's actually get people to review kernel commits please.
Fixes xHC crashes and IOMMU faults with UAS devices when handling
errors/faults. Easiest repro is to use `hdparm` to mark an early sector
(e.g. 1024) on a disk as bad, then `cat /dev/sdX > /dev/null` in a loop.
At least in the case of JMicron controllers, the read errors end up
having to cancel two TDs (for two queued requests to different streams)
and the one that didn't get cleared properly ends up faulting the xHC
entirely when it tries to access DMA pages that have since been unmapped,
referred to by the stale TDs. This normally happens quickly (after two
or three loops). After this fix, I left the `cat` in a loop running
overnight and experienced no xHC failures, with all read errors
recovered properly. Repro'd and tested on an Apple M1 Mac Mini
(dwc3 host).
On systems without an IOMMU, this bug would instead silently corrupt
freed memory, making this a security bug (even on systems with IOMMUs
this could silently corrupt memory belonging to other USB devices on the
same controller, so it's still a security bug). Given that the kernel
autoprobes partition tables, I'm pretty sure a malicious USB device
pretending to be a UAS device and reporting an error with the right
timing could deliberately trigger a UAF and write to freed memory, with
no user action.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Breno Leitao <leitao@debian.org>
commit 4254dfeda82f20844299dca6c38cbffcfd499f41 upstream.
There is a potential out-of-bounds access when using test_bit() on a single
word. The test_bit() and set_bit() functions operate on long values, and
when testing or setting a single word, they can exceed the word
boundary. KASAN detects this issue and produces a dump:
BUG: KASAN: slab-out-of-bounds in _scsih_add_device.constprop.0 (./arch/x86/include/asm/bitops.h:60 ./include/asm-generic/bitops/instrumented-atomic.h:29 drivers/scsi/mpt3sas/mpt3sas_scsih.c:7331) mpt3sas
Write of size 8 at addr ffff8881d26e3c60 by task kworker/u1536:2/2965
For full log, please look at [1].
Make the allocation at least the size of sizeof(unsigned long) so that
set_bit() and test_bit() have sufficient room for read/write operations
without overwriting unallocated memory.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@ellerman.id.au>
commit 2d43cc701b96f910f50915ac4c2a0cae5deb734c upstream.
Building ppc64le_defconfig with GCC 14 fails with assembler errors:
CC fs/readdir.o
/tmp/ccdQn0mD.s: Assembler messages:
/tmp/ccdQn0mD.s:212: Error: operand out of domain (18 is not a multiple of 4)
/tmp/ccdQn0mD.s:226: Error: operand out of domain (18 is not a multiple of 4)
... [6 lines]
/tmp/ccdQn0mD.s:1699: Error: operand out of domain (18 is not a multiple of 4)
A snippet of the asm shows:
# ../fs/readdir.c:210: unsafe_copy_dirent_name(dirent->d_name, name, namlen, efault_end);
ld 9,0(29) # MEM[(u64 *)name_38(D) + _88 * 1], MEM[(u64 *)name_38(D) + _88 * 1]
# 210 "../fs/readdir.c" 1
1: std 9,18(8) # put_user # *__pus_addr_52, MEM[(u64 *)name_38(D) + _88 * 1]
The 'std' instruction requires a 4-byte aligned displacement because
it is a DS-form instruction, and as the assembler says, 18 is not a
multiple of 4.
A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y.
The fix is to change the constraint on the memory operand to put_user(),
from "m" which is a general memory reference to "YZ".
The "Z" constraint is documented in the GCC manual PowerPC machine
constraints, and specifies a "memory operand accessed with indexed or
indirect addressing". "Y" is not documented in the manual but specifies
a "memory operand for a DS-form instruction". Using both allows the
compiler to generate a DS-form "std" or X-form "stdx" as appropriate.
The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because
the "Y" constraint does not guarantee 4-byte alignment when prefixed
instructions are enabled.
Unfortunately clang doesn't support the "Y" constraint so that has to be
behind an ifdef.
Although the build error is only seen with GCC 13/14, that appears
to just be luck. The constraint has been incorrect since it was first
added.
Fixes: c20beffeec3c ("powerpc/uaccess: Use flexible addressing with __put_user()/__get_user()")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
commit 0774d19038c496f0c3602fb505c43e1b2d8eed85 upstream.
If an input device declares too many capability bits then modalias
string for such device may become too long and not fit into uevent
buffer, resulting in failure of sending said uevent. This, in turn,
may prevent userspace from recognizing existence of such devices.
This is typically not a concern for real hardware devices as they have
limited number of keys, but happen with synthetic devices such as
ones created by xen-kbdfront driver, which creates devices as being
capable of delivering all possible keys, since it doesn't know what
keys the backend may produce.
To deal with such devices input core will attempt to trim key data,
in the hope that the rest of modalias string will fit in the given
buffer. When trimming key data it will indicate that it is not
complete by placing "+," sign, resulting in conversions like this:
old: k71,72,73,74,78,7A,7B,7C,7D,8E,9E,A4,AD,E0,E1,E4,F8,174,
new: k71,72,73,74,78,7A,7B,7C,+,
This should allow existing udev rules continue to work with existing
devices, and will also allow writing more complex rules that would
recognize trimmed modalias and check input device characteristics by
other means (for example by parsing KEY= data in uevent or parsing
input device sysfs attributes).
Note that the driver core may try adding more uevent environment
variables once input core is done adding its own, so when forming
modalias we can not use the entire available buffer, so we reduce
it by somewhat an arbitrary amount (96 bytes).

------------------
From: Samuel Holland <samuel.holland@sifive.com>
[ Upstream commit 2607133196c35f31892ee199ce7ffa717bea4ad1 ]
These clkdevs were unnecessary, because systems using this driver always
look up clocks using the devicetree. And as Russell King points out[1],
since the provided device name was truncated, lookups via clkdev would
never match.
Recently, commit 8d532528ff6a ("clkdev: report over-sized strings when
creating clkdev entries") caused clkdev registration to fail due to the
truncation, and this now prevents the driver from probing. Fix the
driver by removing the clkdev registration.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit 1981b296f858010eae409548fd297659b2cc570e ]
When reading token data from sysfs on my Inspiron 3505, the token
locations and values are wrong. This happens because match_attribute()
blindly assumes that all entries in da_tokens have an associated
entry in token_attrs.
This however is not true as soon as da_tokens[] contains zeroed
token entries. Those entries are being skipped when initialising
token_attrs, breaking the core assumption of match_attribute().
Fix this by defining an extra struct for each pair of token attributes
and use container_of() to retrieve token information.
Tested on a Dell Inspiron 3050.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Schiffer <matthias.schiffer@ew.tq-group.com>
commit 08af509efdf8dad08e972b48de0e2c2a7919ea8b upstream.
irq_set_type() should not implicitly unmask the IRQ.
All accesses to the interrupt configuration register are moved to a new
helper tqmx86_gpio_irq_config(). We also introduce the new rule that
accessing irq_type must happen while locked, which will become
significant for fixing EDGE_BOTH handling.

[ Upstream commit 4aa2dcfbad538adf7becd0034a3754e1bd01b2b5 ]
Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.
Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
...
value &= m;
...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vasant Hegde <vasant.hegde@amd.com>
[ Upstream commit 404ec4e4c169fb64da6b2a38b471c13ac0897c76 ]
Newer AMD systems can support multiple PCI segments, where each segment
contains one or more IOMMU instances. However, an IOMMU instance can only
support a single PCI segment.
Current code assumes that system contains only one pci segment (segment 0)
and creates global data structures such as device table, rlookup table,
etc.
Introducing per PCI segment data structure, which contains segment
specific data structures. This will eventually replace the global
data structures.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lu Baolu <baolu.lu@linux.intel.com>
[ Upstream commit 89e8a2366e3bce584b6c01549d5019c5cda1205e ]
iommu_sva_bind_device() should return either a sva bond handle or an
ERR_PTR value in error cases. Existing drivers (idxd and uacce) only
check the return value with IS_ERR(). This could potentially lead to
a kernel NULL pointer dereference issue if the function returns NULL
instead of an error pointer.
In reality, this doesn't cause any problems because iommu_sva_bind_device()
only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.
In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will
return an error, and the device drivers won't call iommu_sva_bind_device()
at all.

not be run. As a consequence, `sfp_hwmon_remove()` is not getting
run either, leaving a stale `hwmon` device behind. `sfp_sm_mod_remove()`
itself checks `sfp->sm_mod_state` anyways, so this check was not
really needed in the first place.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jie Wang <wangjie125@huawei.com>
[ Upstream commit 968fde83841a8c23558dfbd0a0c69d636db52b55 ]
Currently hns3 ring buffer init process would hold cpu too long with big
Tx/Rx ring depth. This could cause soft lockup.
So this patch adds cond_resched() to the process. Then cpu can break to
run other tasks instead of busy looping.
Fixes: a723fb8efe29 ("net: hns3: refine for set ring parameters")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aleksandr Mishin <amishin@t-argos.ru>
[ Upstream commit c44711b78608c98a3e6b49ce91678cd0917d5349 ]
In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value,
but then it is unconditionally passed to skb_add_rx_frag() which looks
strange and could lead to null pointer dereference.
lio_vf_rep_copy_packet() call trace looks like:
octeon_droq_process_packets
octeon_droq_fast_process_packets
octeon_droq_dispatch_pkt
octeon_create_recv_info
...search in the dispatch_list...
->disp_fn(rdisp->rinfo, ...)
lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...)
In this path there is no code which sets pg_info->page to NULL.
So this check looks unneeded and doesn't solve potential problem.
But I guess the author had reason to add a check and I have no such card
and can't do real test.
In addition, the code in the function liquidio_push_packet() in
liquidio/lio_core.c does exactly the same.
Based on this, I consider the most acceptable compromise solution to
adjust this issue by moving skb_add_rx_frag() into conditional scope.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

From: Adam Miotk <adam.miotk@arm.com>
[ Upstream commit ce62600c4dbee8d43b02277669dd91785a9b81d9 ]
Device managed panel bridge wrappers are created by calling to
drm_panel_bridge_add_typed() and registering a release handler for
clean-up when the device gets unbound.
Since the memory for this bridge is also managed and linked to the panel
device, the release function should not try to free that memory.
Moreover, the call to devm_kfree() inside drm_panel_bridge_remove() will
fail in this case and emit a warning because the panel bridge resource
is no longer on the device resources list (it has been removed from
there before the call to release handlers).

From: Eric Dumazet <edumazet@google.com>
[ Upstream commit d37fe4255abe8e7b419b90c5847e8ec2b8debb08 ]
tcp_v6_syn_recv_sock() calls ip6_dst_store() before
inet_sk(newsk)->pinet6 has been set up.
This means ip6_dst_store() writes over the parent (listener)
np->dst_cookie.
This is racy because multiple threads could share the same
parent and their final np->dst_cookie could be wrong.
Move ip6_dst_store() call after inet_sk(newsk)->pinet6
has been changed and after the copy of parent ipv6_pinfo.

Move the vxlan_features_check() call to after we verified the packet is
a tunneled VXLAN packet.
Without this, tunneled UDP non-VXLAN packets (for ex. GENENVE) might
wrongly not get offloaded.
In some cases, it worked by chance as GENEVE header is the same size as
VXLAN, but it is obviously incorrect.

the later is just the initial maximum conn interval not the maximum the

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jozsef Kadlecsik <kadlec@netfilter.org>
[ Upstream commit 4e7aaa6b82d63e8ddcbfb56b4fd3d014ca586f10 ]
Lion Ackermann reported that there is a race condition between namespace cleanup
in ipset and the garbage collection of the list:set type. The namespace
cleanup can destroy the list:set type of sets while the gc of the set type is
waiting to run in rcu cleanup. The latter uses data from the destroyed set which
thus leads use after free. The patch contains the following parts:
- When destroying all sets, first remove the garbage collectors, then wait
if needed and then destroy the sets.
- Fix the badly ordered "wait then remove gc" for the destroy a single set
case.
- Fix the missing rcu locking in the list:set type in the userspace test
case.
- Use proper RCU list handlings in the list:set type.
The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc).
Fixes: 97f7cf1cd80e (netfilter: ipset: fix performance regression in swap operation)

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xiaolei Wang <xiaolei.wang@windriver.com>
[ Upstream commit be27b896529787e23a35ae4befb6337ce73fcca0 ]
The current cbs parameter depends on speed after uplinking,
which is not needed and will report a configuration error
if the port is not initially connected. The UAPI exposed by
tc-cbs requires userspace to recalculate the send slope anyway,
because the formula depends on port_transmit_rate (see man tc-cbs),
which is not an invariant from tc's perspective. Therefore, we
use offload->sendslope and offload->idleslope to derive the
original port_transmit_rate from the CBS formula.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Petr Pavlu <petr.pavlu@suse.com>
[ Upstream commit 14a20e5b4ad998793c5f43b0330d9e1388446cf3 ]
The net.ipv6.route.flush system parameter takes a value which specifies
a delay used during the flush operation for aging exception routes. The
written value is however not used in the currently requested flush and
instead utilized only in the next one.
A problem is that ipv6_sysctl_rtcache_flush() first reads the old value
of net->ipv6.sysctl.flush_delay into a local delay variable and then
calls proc_dointvec() which actually updates the sysctl based on the
provided input.
Fix the problem by switching the order of the two operations.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Taehee Yoo <ap420073@gmail.com>
[ Upstream commit 79f18a41dd056115d685f3b0a419c7cd40055e13 ]
When queues are started, netif_napi_add() and napi_enable() are called.
If there are 4 queues and only 3 queues are used for the current
configuration, only 3 queues' napi should be registered and enabled.
The ionic_qcq_enable() checks whether the .poll pointer is not NULL for
enabling only the using queue' napi. Unused queues' napi will not be
registered by netif_napi_add(), so the .poll pointer indicates NULL.
But it couldn't distinguish whether the napi was unregistered or not
because netif_napi_del() doesn't reset the .poll pointer to NULL.
So, ionic_qcq_enable() calls napi_enable() for the queue, which was
unregistered by netif_napi_del().
Reproducer:
ethtool -L <interface name> rx 1 tx 1 combined 0
ethtool -L <interface name> rx 0 tx 0 combined 1
ethtool -L <interface name> rx 0 tx 0 combined 4

From: Rao Shoaib <Rao.Shoaib@oracle.com>
[ Upstream commit a6736a0addd60fccc3a3508461d72314cc609772 ]
Read with MSG_PEEK flag loops if the first byte to read is an OOB byte.
commit 22dd70eb2c3d ("af_unix: Don't peek OOB data without MSG_OOB.")
addresses the loop issue but does not address the issue that no data
beyond OOB byte can be read.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Lechner <dlechner@baylibre.com>
commit 8a01ef749b0a632f0e1f4ead0f08b3310d99fcb1 upstream.
According to the IIO documentation, the sign in the scan type should be
lower case. The ad9467 driver was incorrectly using upper case.
Fix by changing to lower case.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Ferland <marc.ferland@sonatest.com>
commit 279428df888319bf68f2686934897301a250bb84 upstream.
The scale value for the temperature channel is (assuming Vref=2.5 and
the datasheet):
376.7897513
When calculating both val and val2 for the temperature scale we
use (3767897513/25) and multiply it by Vref (here I assume 2500mV) to
obtain:
2500 * (3767897513/25) ==> 376789751300
Finally we divide with remainder by 10^9 to get:
val = 376
val2 = 789751300
However, we return IIO_VAL_INT_PLUS_MICRO (should have been NANO) as
the scale type. So when converting the raw temperature value to the
'processed' temperature value we will get (assuming raw=810,
offset=-753):
processed = (raw + offset) * scale_val
= (810 + -753) * 376
= 21432
processed += div((raw + offset) * scale_val2, 10^6)
+= div((810 + -753) * 789751300, 10^6)
+= 45015
==> 66447
==> 66.4 Celcius
instead of the expected 21.5 Celsius.
Fix this issue by changing IIO_VAL_INT_PLUS_MICRO to
IIO_VAL_INT_PLUS_NANO.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dirk Behme <dirk.behme@de.bosch.com>
commit c0a40097f0bc81deafc15f9195d1fb54595cd6d0 upstream.
Synchronize the dev->driver usage in really_probe() and dev_uevent().
These can run in different threads, what can result in the following
race condition for dev->driver uninitialization:
Thread #1:
==========
really_probe() {
...
probe_failed:
...
device_unbind_cleanup(dev) {
...
dev->driver = NULL; // <= Failed probe sets dev->driver to NULL
...
}
...
}
Thread #2:
==========
dev_uevent() {
...
if (dev->driver)
// If dev->driver is NULLed from really_probe() from here on,
// after above check, the system crashes
add_uevent_var(env, "DRIVER=%s", dev->driver->name);
...
}
really_probe() holds the lock, already. So nothing needs to be done
there. dev_uevent() is called with lock held, often, too. But not
always. What implies that we can't add any locking in dev_uevent()
itself. So fix this race by adding the lock to the non-protected
path. This is the path where above race is observed:
dev_uevent+0x235/0x380
uevent_show+0x10c/0x1f0 <= Add lock here

Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the *initialization* of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered
to be false-positives (which should be "fixed" by this commit, as well,
though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/
already.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Szyprowski <m.szyprowski@samsung.com>
commit 799d4b392417ed6889030a5b2335ccb6dcf030ab upstream.
When reading EDID fails and driver reports no modes available, the DRM
core adds an artificial 1024x786 mode to the connector. Unfortunately
some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not
able to drive such mode, so report a safe 640x480 mode instead of nothing
in case of the EDID reading failure.
This fixes the following issue observed on Trats2 board since commit
13d5b040363c ("drm/exynos: do not return negative values from .get_modes()"):

------------------
From: Paolo Abeni <pabeni@redhat.com>
commit 8031b58c3a9b1db3ef68b3bd749fbee2e1e1aaa3 upstream.
This is strictly related to commit fb7a0d334894 ("mptcp: ensure snd_nxt
is properly initialized on connect"). It turns out that syzkaller can
trigger the retransmit after fallback and before processing any other
incoming packet - so that snd_una is still left uninitialized.
Address the issue explicitly initializing snd_una together with snd_nxt
and write_seq.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt (Google) <rostedt@goodmis.org>
commit 23a4b108accc29a6125ed14de4a044689ffeda78 upstream.
The kprobe_eventname.tc test checks if a function with .isra. can have a
kprobe attached to it. It loops through the kallsyms file for all the
functions that have the .isra. name, and checks if it exists in the
available_filter_functions file, and if it does, it uses it to attach a
kprobe to it.
The issue is that kprobes can not attach to functions that are listed more
than once in available_filter_functions. With the latest kernel, the
function that is found is: rapl_event_update.isra.0
# grep rapl_event_update.isra.0 /sys/kernel/tracing/available_filter_functions
rapl_event_update.isra.0
rapl_event_update.isra.0
It is listed twice. This causes the attached kprobe to it to fail which in
turn fails the test. Instead of just picking the function function that is
found in available_filter_functions, pick the first one that is listed
only once in available_filter_functions.

From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
commit 4b4647add7d3c8530493f7247d11e257ee425bf0 upstream.
sk_psock_get will return NULL if the refcount of psock has gone to 0, which
will happen when the last call of sk_psock_put is done. However,
sk_psock_drop may not have finished yet, so the close callback will still
point to sock_map_close despite psock being NULL.
This can be reproduced with a thread deleting an element from the sock map,
while the second one creates a socket, adds it to the map and closes it.

Use sk_psock, which will only check that the pointer is not been set to
NULL yet, which should only happen after the callbacks are restored. If,
then, a reference can still be gotten, we may call sk_psock_stop and cancel
psock->work.
As suggested by Paolo Abeni, reorder the condition so the control flow is
less convoluted.
After that change, the reproducer does not trigger the WARN_ON_ONCE
anymore.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hagar Gamal Halim Hemdan <hagarhem@amazon.com>
commit 8003f00d895310d409b2bf9ef907c56b42a4e0f4 upstream.
Coverity spotted that event_msg is controlled by user-space,
event_msg->event_data.event is passed to event_deliver() and used
as an index without sanitization.
This change ensures that the event index is sanitized to mitigate any
possibility of speculative information leaks.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.
Only compile tested, no access to HW.

'nr' member of struct spmi_controller, which serves as an identifier

From: Trond Myklebust <trond.myklebust@hammerspace.com>
commit e221c45da3770962418fb30c27d941bbc70d595a upstream.
The 'NFS error' NFSERR_OPNOTSUPP is not described by any of the official
NFS related RFCs, but appears to have snuck into some older .x files for
NFSv2.
Either way, it is not in RFC1094, RFC1813 or any of the NFSv4 RFCs, so
should not be returned by the knfsd server, and particularly not by the
"LOOKUP" operation.
Instead, let's return NFSERR_STALE, which is more appropriate if the
filesystem encodes the filehandle as FILEID_INVALID.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rik van Riel <riel@surriel.com>
commit 5cbcb62dddf5346077feb82b7b0c9254222d3445 upstream.
While taking a kernel core dump with makedumpfile on a larger system,
softlockup messages often appear.
While softlockup warnings can be harmless, they can also interfere with
things like RCU freeing memory, which can be problematic when the kdump
kexec image is configured with as little memory as possible.
Avoid the softlockup, and give things like work items and RCU a chance to
do their thing during __read_vmcore by adding a cond_resched.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Su Yue <glass.su@suse.com>
commit b8cb324277ee16f3eca3055b96fce4735a5a41c6 upstream.
The default atime related mount option is '-o realtime' which means file
atime should be updated if atime <= ctime or atime <= mtime. atime should
be updated in the following scenario, but it is not:
==========================================================
$ rm /mnt/testfile;
$ echo test > /mnt/testfile
$ stat -c "%X %Y %Z" /mnt/testfile
1711881646 1711881646 1711881646
$ sleep 5
$ cat /mnt/testfile > /dev/null
$ stat -c "%X %Y %Z" /mnt/testfile
1711881646 1711881646 1711881646
==========================================================
And the reason the atime in the test is not updated is that ocfs2 calls
ktime_get_real_ts64() in __ocfs2_mknod_locked during file creation. Then
inode_set_ctime_current() is called in inode_set_ctime_current() calls
ktime_get_coarse_real_ts64() to get current time.
ktime_get_real_ts64() is more accurate than ktime_get_coarse_real_ts64().
In my test box, I saw ctime set by ktime_get_coarse_real_ts64() is less
than ktime_get_real_ts64() even ctime is set later. The ctime of the new
inode is smaller than atime.
The call trace is like:
ocfs2_create
ocfs2_mknod
__ocfs2_mknod_locked
....
ktime_get_real_ts64 <------- set atime,ctime,mtime, more accurate
ocfs2_populate_inode
...
ocfs2_init_acl
ocfs2_acl_set_mode
inode_set_ctime_current
current_time
ktime_get_coarse_real_ts64 <-------less accurate
ocfs2_file_read_iter
ocfs2_inode_lock_atime
ocfs2_should_update_atime
atime <= ctime ? <-------- false, ctime < atime due to accuracy
So here call ktime_get_coarse_real_ts64 to set inode time coarser while
creating new files. It may lower the accuracy of file times. But it's
not a big deal since we already use coarse time in other places like
ocfs2_update_inode_atime and inode_set_ctime_current.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Su Yue <glass.su@suse.com>
commit 952b023f06a24b2ad6ba67304c4c84d45bea2f18 upstream.
After commit "ocfs2: return real error code in ocfs2_dio_wr_get_block",
fstests/generic/300 become from always failed to sometimes failed:

=========================================================================
In __blockdev_direct_IO, ocfs2_dio_wr_get_block is called to add unwritten
extents to a list. extents are also inserted into extent tree in
ocfs2_write_begin_nolock. Then another thread call fallocate to puch a
hole at one of the unwritten extent. The extent at cpos was removed by
ocfs2_remove_extent(). At end io worker thread, ocfs2_search_extent_list
found there is no such extent at the cpos.

In most filesystems, fallocate is not compatible with racing with AIO+DIO,
so fix it by adding to wait for all dio before fallocate/punch_hole like
ext4.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rick Wertenbroek <rick.wertenbroek@gmail.com>
commit 2dba285caba53f309d6060fca911b43d63f41697 upstream.
Remove wrong mask on subsys_vendor_id. Both the Vendor ID and Subsystem
Vendor ID are u16 variables and are written to a u32 register of the
controller. The Subsystem Vendor ID was always 0 because the u16 value
was masked incorrectly with GENMASK(31,16) resulting in all lower 16
bits being set to 0 prior to the shift.
Remove both masks as they are unnecessary and set the register correctly
i.e., the lower 16-bits are the Vendor ID and the upper 16-bits are the
Subsystem Vendor ID.
This is documented in the RK3399 TRM section 17.6.7.1.17
[kwilczynski: removed unnecesary newline]

From: Nuno Sa <nuno.sa@analog.com>
commit 1bc31444209c8efae98cb78818131950d9a6f4d6 upstream.
We need to first free the IRQ before calling of_dma_controller_free().
Otherwise we could get an interrupt and schedule a tasklet while
removing the DMA controller.

This is because when the log writer starts a writeback for segment summary
blocks or a super root block that use the backing device's page cache, it
does not wait for the ongoing folio/page writeback, resulting in an
inconsistent writeback state.
Fix this issue by waiting for ongoing writebacks when putting
folios/pages on the backing device into writeback state.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oleg Nesterov <oleg@redhat.com>
commit 07c54cc5988f19c9642fd463c2dbdac7fc52f777 upstream.
After the recent commit 5097cbcb38e6 ("sched/isolation: Prevent boot crash
when the boot CPU is nohz_full") the kernel no longer crashes, but there is
another problem.
In this case tick_setup_device() calls tick_take_do_timer_from_boot() to
update tick_do_timer_cpu and this triggers the WARN_ON_ONCE(irqs_disabled)
in smp_call_function_single().
Kill tick_take_do_timer_from_boot() and just use WRITE_ONCE(), the new
comment explains why this is safe (thanks Thomas!).
Fixes: 08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Damien Le Moal <dlemoal@kernel.org>
commit 90e6f08915ec6efe46570420412a65050ec826b2 upstream.
The function mpi3mr_qcmd() of the mpi3mr driver is able to indicate to
the HBA if a read or write command directed at an ATA device should be
translated to an NCQ read/write command with the high prioiryt bit set
when the request uses the RT priority class and the user has enabled NCQ
priority through sysfs.
However, unlike the mpt3sas driver, the mpi3mr driver does not define
the sas_ncq_prio_supported and sas_ncq_prio_enable sysfs attributes, so
the ncq_prio_enable field of struct mpi3mr_sdev_priv_data is never
actually set and NCQ Priority cannot ever be used.
Fix this by defining these missing atributes to allow a user to check if
an ATA device supports NCQ priority and to enable/disable the use of NCQ
priority. To do this, lift the function scsih_ncq_prio_supp() out of the
mpt3sas driver and make it the generic SCSI SAS transport function
sas_ata_ncq_prio_supported(). Nothing in that function is hardware
specific, so this function can be used in both the mpt3sas driver and
the mpi3mr driver.

The root cause is that HWPoison flag will be set for huge_zero_folio
without increasing the folio refcnt. But then unpoison_memory() will
decrease the folio refcnt unexpectedly as it appears like a successfully
hwpoisoned folio leading to VM_BUG_ON_PAGE(page_ref_count(page) == 0) when
releasing huge_zero_folio.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Doug Brown <doug@schmorgal.com>
commit 5208e7ced520a813b4f4774451fbac4e517e78b2 upstream.
The FIFO is 64 bytes, but the FCR is configured to fire the TX interrupt
when the FIFO is half empty (bit 3 = 0). Thus, we should only write 32
bytes when a TX interrupt occurs.
This fixes a problem observed on the PXA168 that dropped a bunch of TX
bytes during large transmissions.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Goergens <matthias.goergens@gmail.com>
commit 710bb68c2e3a24512e2d2bae470960d7488e97b1 upstream.
Left-shifting past the size of your datatype is undefined behaviour in C.
The literal 34 gets the type `int`, and that one is not big enough to be
left shifted by 26 bits.
An `unsigned` is long enough (on any machine that has at least 32 bits for
their ints.)
For uniformity, we mark all the literals as unsigned. But it's only
really needed for HUGETLB_FLAG_ENCODE_16GB.
Thanks to Randy Dunlap for an initial review and suggestion.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: YonglongLi <liyonglong@chinatelecom.cn>
commit 6a09788c1a66e3d8b04b3b3e7618cc817bb60ae9 upstream.
The RmAddr MIB counter is supposed to be incremented once when a valid
RM_ADDR has been received. Before this patch, it could have been
incremented as many times as the number of subflows connected to the
linked address ID, so it could have been 0, 1 or more than 1.
The "RmSubflow" is incremented after a local operation. In this case,
it is normal to tied it with the number of subflows that have been
actually removed.
The "remove invalid addresses" MP Join subtest has been modified to
validate this case. A broadcast IP address is now used instead: the
client will not be able to create a subflow to this address. The
consequence is that when receiving the RM_ADDR with the ID attached to
this broadcast IP address, no subflow linked to this ID will be found.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: YonglongLi <liyonglong@chinatelecom.cn>
commit 40eec1795cc27b076d49236649a29507c7ed8c2d upstream.
The creation of new subflows can fail for different reasons. If no
subflow have been created using the received ADD_ADDR, the related
counters should not be updated, otherwise they will never be decremented
for events related to this ID later on.
For the moment, the number of accepted ADD_ADDR is only decremented upon
the reception of a related RM_ADDR, and only if the remote address ID is
currently being used by at least one subflow. In other words, if no
subflow can be created with the received address, the counter will not
be decremented. In this case, it is then important not to increment
pm.add_addr_accepted counter, and not to modify pm.accept_addr bit.
Note that this patch does not modify the behaviour in case of failures
later on, e.g. if the MP Join is dropped or rejected.
The "remove invalid addresses" MP Join subtest has been modified to
validate this case. The broadcast IP address is added before the "valid"
address that will be used to successfully create a subflow, and the
limit is decreased by one: without this patch, it was not possible to
create the last subflow, because:
- the broadcast address would have been accepted even if it was not
usable: the creation of a subflow to this address results in an error,
- the limit of 2 accepted ADD_ADDR would have then been reached.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
commit aba091547ef6159d52471f42a3ef531b7b660ed8 upstream.
There is an issue in clang's ThinLTO caching (enabled for the kernel via
'--thinlto-cache-dir') with .incbin, which the kernel occasionally uses
to include data within the kernel, such as the .config file for
/proc/config.gz. For example, when changing the .config and rebuilding
vmlinux, the copy of .config in vmlinux does not match the copy of
.config in the build folder:
$ echo 'CONFIG_LTO_NONE=n
CONFIG_LTO_CLANG_THIN=y
CONFIG_IKCONFIG=y
CONFIG_HEADERS_INSTALL=y' >kernel/configs/repro.config
$ make -skj"$(nproc)" ARCH=x86_64 LLVM=1 clean defconfig repro.config vmlinux
...
$ grep CONFIG_HEADERS_INSTALL .config
CONFIG_HEADERS_INSTALL=y
$ scripts/extract-ikconfig vmlinux | grep CONFIG_HEADERS_INSTALL
CONFIG_HEADERS_INSTALL=y
$ scripts/config -d HEADERS_INSTALL
$ make -kj"$(nproc)" ARCH=x86_64 LLVM=1 vmlinux
...
UPD kernel/config_data
GZIP kernel/config_data.gz
CC kernel/configs.o
...
LD vmlinux
...
$ grep CONFIG_HEADERS_INSTALL .config
# CONFIG_HEADERS_INSTALL is not set
$ scripts/extract-ikconfig vmlinux | grep CONFIG_HEADERS_INSTALL
CONFIG_HEADERS_INSTALL=y
Without '--thinlto-cache-dir' or when using full LTO, this issue does
not occur.
Benchmarking incremental builds on a few different machines with and
without the cache shows a 20% increase in incremental build time without
the cache when measured by touching init/main.c and running 'make all'.
ARCH=arm64 defconfig + CONFIG_LTO_CLANG_THIN=y on an arm64 host:
Benchmark 1: With ThinLTO cache
Time (mean ± σ): 56.347 s ± 0.163 s [User: 83.768 s, System: 24.661 s]
Range (min … max): 56.109 s … 56.594 s 10 runs
Benchmark 2: Without ThinLTO cache
Time (mean ± σ): 67.740 s ± 0.479 s [User: 718.458 s, System: 31.797 s]
Range (min … max): 67.059 s … 68.556 s 10 runs
Summary
With ThinLTO cache ran
1.20 ± 0.01 times faster than Without ThinLTO cache
ARCH=x86_64 defconfig + CONFIG_LTO_CLANG_THIN=y on an x86_64 host:
Benchmark 1: With ThinLTO cache
Time (mean ± σ): 85.772 s ± 0.252 s [User: 91.505 s, System: 8.408 s]
Range (min … max): 85.447 s … 86.244 s 10 runs
Benchmark 2: Without ThinLTO cache
Time (mean ± σ): 103.833 s ± 0.288 s [User: 232.058 s, System: 8.569 s]
Range (min … max): 103.286 s … 104.124 s 10 runs
Summary
With ThinLTO cache ran
1.21 ± 0.00 times faster than Without ThinLTO cache
While it is unfortunate to take this performance improvement off the
table, correctness is more important. If/when this is fixed in LLVM, it
can potentially be brought back in a conditional manner. Alternatively,
a developer can just disable LTO if doing incremental compiles quickly
is important, as a full compile cycle can still take over a minute even
with the cache and it is unlikely that LTO will result in functional
differences for a kernel change.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sicong Huang <congei42@163.com>
commit 5c9c5d7f26acc2c669c1dcf57d1bb43ee99220ce upstream.
In gb_interface_create, &intf->mode_switch_completion is bound with
gb_interface_mode_switch_work. Then it will be started by
gb_interface_request_mode_switch. Here is the relevant code.
if (!queue_work(system_long_wq, &intf->mode_switch_work)) {
...
}
If we call gb_interface_release to make cleanup, there may be an
unfinished work. This function will call kfree to free the object
"intf". However, if gb_interface_mode_switch_work is scheduled to
run after kfree, it may cause use-after-free error as
gb_interface_mode_switch_work will use the object "intf".
The possible execution flow that may lead to the issue is as follows:
CPU0 CPU1
| gb_interface_create
| gb_interface_request_mode_switch
gb_interface_release |
kfree(intf) (free) |
| gb_interface_mode_switch_work
| mutex_lock(&intf->mutex) (use)
Fix it by canceling the work before kfree.

From: Shichao Lai <shichaorai@gmail.com>
[ Upstream commit 16637fea001ab3c8df528a8995b3211906165a30 ]
The member "uzonesize" of struct alauda_info will remain 0
if alauda_init_media() fails, potentially causing divide errors
in alauda_read_data() and alauda_write_lba().
- Add a member "media_initialized" to struct alauda_info.
- Change a condition in alauda_check_media() to ensure the
first initialization.
- Add an error check for the return value of alauda_init_media().

[ Upstream commit 7fea700e04bd3f424c2d836e98425782f97b494e ]
kernel_wait4() doesn't sleep and returns -EINTR if there is no
eligible child and signal_pending() is true.
That is why zap_pid_ns_processes() clears TIF_SIGPENDING but this is not
enough, it should also clear TIF_NOTIFY_SIGNAL to make signal_pending()
return false and avoid a busy-wait loop.

As the old padata code can execute in softirq context, disable
softirqs for the new padata_do_mutithreaded code too as otherwise
lockdep will get antsy.

[ Upstream commit 431315a563015f259b28e34c5842f6166439e969 ]
When the rcutorture tests start to exit, the rcu_torture_cleanup() is
invoked to stop kthreads and release resources, if the stall-task
kthreads exist, cpu-stall has started and the rcutorture.stall_cpu
is set to a larger value, the rcu_torture_cleanup() will be blocked
for a long time and the hung-task may occur, this commit therefore
add kthread_should_stop() to the loop of cpu-stall operation, when
rcutorture tests ends, no need to wait for cpu-stall to end, exit
directly.
Use the following command to test:
insmod rcutorture.ko torture_type=srcu fwd_progress=0 stat_interval=4
stall_cpu_block=1 stall_cpu=200 stall_cpu_holdoff=10 read_exit_burst=0

This commit therefore use smp_call_on_cpu() instead of
smp_call_function_single(), make rcu_torture_barrier1cb() invoked

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang; It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").
Let's rework this overflow checking logic to not actually perform an
overflow during the check itself, thus avoiding the UBSAN splat.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alessandro Carminati (Red Hat) <alessandro.carminati@gmail.com>
[ Upstream commit f803bcf9208a2540acb4c32bdc3616673169f490 ]
In some systems, the netcat server can incur in delay to start listening.
When this happens, the test can randomly fail in various points.
This is an example error message:
# ip gre none gso
# encap 192.168.1.1 to 192.168.1.2, type gre, mac none len 2000
# test basic connectivity
# Ncat: Connection refused.
The issue stems from a race condition between the netcat client and server.
The test author had addressed this problem by implementing a sleep, which
I have removed in this patch.
This patch introduces a function capable of sleeping for up to two seconds.
However, it can terminate the waiting period early if the port is reported
to be listening.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit 14bb1e8c8d4ad5d9d2febb7d19c70a3cf536e1e5 ]
Recently, I frequently hit the following test failure:
[root@arch-fb-vm1 bpf]# ./test_progs -n 33/1
test_lookup_update:PASS:skel_open 0 nsec
[...]
test_lookup_update:PASS:sync_rcu 0 nsec
test_lookup_update:FAIL:map1_leak inner_map1 leaked!
#33/1 btf_map_in_map/lookup_update:FAIL
#33 btf_map_in_map:FAIL
In the test, after map is closed and then after two rcu grace periods,
it is assumed that map_id is not available to user space.
But the above assumption cannot be guaranteed. After zero or one
or two rcu grace periods in different siturations, the actual
freeing-map-work is put into a workqueue. Later on, when the work
is dequeued, the map will be actually freed.
See bpf_map_put() in kernel/bpf/syscall.c.
By using workqueue, there is no ganrantee that map will be actually
freed after a couple of rcu grace periods. This patch removed
such map leak detection and then the test can pass consistently.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 40dc8ab605894acae1473e434944924a22cfaaa0 ]
Many syzbot reports are pointing to soft lockups in
batadv_purge_orig_ref() [1]
Root cause is unknown, but we can avoid spending too much
time there and perhaps get more interesting reports.
[1]
watchdog: BUG: soft lockup - CPU#0 stuck for 27s! [kworker/u4:6:621]

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 61752ac69b69ed2e04444d090f6917c77ab36d42 ]
gcc-9 and some other older versions produce a false-positive warning
for zeroing two fields
In file included from include/linux/string.h:369,
from drivers/net/wireless/ath/ath9k/main.c:18:
In function 'fortify_memset_chk',
inlined from 'ath9k_ps_wakeup' at drivers/net/wireless/ath/ath9k/main.c:140:3:
include/linux/fortify-string.h:462:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
462 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Using a struct_group seems to reliably avoid the warning and
not make the code much uglier. The combined memset() should even
save a couple of cpu cycles.

Although the code is correct, the following line
copy_from_sockptr(&req_u.req, optval, len));
triggers this warning :
memcpy: detected field-spanning write (size 28) of single field "dst" at include/linux/sockptr.h:49 (size 16)

[ Upstream commit f1e197a665c2148ebc25fe09c53689e60afea195 ]
trace_drop_common() is called with preemption disabled, and it acquires
a spin_lock. This is problematic for RT kernels because spin_locks are
sleeping locks in this configuration, which causes the following splat:

trace_drop_common() also disables interrupts, but this is a minor issue
because we could easily replace it with a local_lock.
Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic
context.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Manish Rangankar <mrangankar@marvell.com>
[ Upstream commit 28027ec8e32ecbadcd67623edb290dad61e735b5 ]
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly
on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then
call simple_read_from_buffer(), which in turns make the copy_to_user()
call.

From: Kunwu Chan <chentao@kylinos.cn>
[ Upstream commit 80164282b3620a3cb73de6ffda5592743e448d0e ]
There is a 'malloc' call, which can be unsuccessful.
This patch will add the malloc failure checking
to avoid possible null dereference and give more information
about test fail reasons.

------------------
From: Breno Leitao <leitao@debian.org>
[ Upstream commit c2e6a872bde9912f1a7579639c5ca3adf1003916 ]
KCSAN detected a race condition in netpoll:
BUG: KCSAN: data-race in net_rx_action / netpoll_send_skb
write (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10:
net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822)
<snip>
read to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2:
netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393)
netpoll_send_udp (net/core/netpoll.c:?)
<snip>
value changed: 0x0000000a -> 0xffffffff
This happens because netpoll_owner_active() needs to check if the
current CPU is the owner of the lock, touching napi->poll_owner
non atomically. The ->poll_owner field contains the current CPU holding
the lock.
Use an atomic read to check if the poll owner is the current CPU.

[ Upstream commit c901f63dc142c48326931f164f787dfff69273d9 ]
Lenovo Slim 7 16ARH7 is a machine with switchable graphics between AMD
and Nvidia, and the backlight can't be adjusted properly unless
acpi_backlight=native is passed. Although nvidia-wmi-backlight is
present and loaded, this doesn't work as expected at all.
For making it working as default, add the corresponding quirk entry
with a DMI matching "LENOVO" "82UX".

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
[ Upstream commit f30a3bea92bdab398531129d187629fb1d28f598 ]
[WHY]
PSP can access DCN registers during command submission and we need
to ensure that DCN is not in PG before doing so.
[HOW]
Add a callback to DM to lock and notify DC for idle optimization exit.
It can't be DC directly because of a potential race condition with the
link protection thread and the rest of DM operation.

[ Upstream commit 49c13b4d2dd4a831225746e758893673f6ae961c ]
This is needed because we want to reset those devices in device-agnostic
code such as lima_sched.
In particular, masking irqs will be useful before a hard reset to
prevent race conditions.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Erico Nunes <nunes.erico@gmail.com>
[ Upstream commit a421cc7a6a001b70415aa4f66024fa6178885a14 ]
There is a race condition in which a rendering job might take just long
enough to trigger the drm sched job timeout handler but also still
complete before the hard reset is done by the timeout handler.
This runs into race conditions not expected by the timeout handler.
In some very specific cases it currently may result in a refcount
imbalance on lima_pm_idle, with a stack dump such as:
[10136.669170] WARNING: CPU: 0 PID: 0 at drivers/gpu/drm/lima/lima_devfreq.c:205 lima_devfreq_record_idle+0xa0/0xb0
...
[10136.669459] pc : lima_devfreq_record_idle+0xa0/0xb0
...
[10136.669628] Call trace:
[10136.669634] lima_devfreq_record_idle+0xa0/0xb0
[10136.669646] lima_sched_pipe_task_done+0x5c/0xb0
[10136.669656] lima_gp_irq_handler+0xa8/0x120
[10136.669666] __handle_irq_event_percpu+0x48/0x160
[10136.669679] handle_irq_event+0x4c/0xc0
We can prevent that race condition entirely by masking the irqs at the
beginning of the timeout handler, at which point we give up on waiting
for that job entirely.
The irqs will be enabled again at the next hard reset which is already
done as a recovery by the timeout handler.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Lynch <nathanl@linux.ibm.com>
[ Upstream commit ff2e185cf73df480ec69675936c4ee75a445c3e4 ]
plpar_hcall(), plpar_hcall9(), and related functions expect callers to
provide valid result buffers of certain minimum size. Currently this
is communicated only through comments in the code and the compiler has
no idea.
For example, if I write a bug like this:
long retbuf[PLPAR_HCALL_BUFSIZE]; // should be PLPAR_HCALL9_BUFSIZE
plpar_hcall9(H_ALLOCATE_VAS_WINDOW, retbuf, ...);
This compiles with no diagnostics emitted, but likely results in stack
corruption at runtime when plpar_hcall9() stores results past the end
of the array. (To be clear this is a contrived example and I have not
found a real instance yet.)
To make this class of error less likely, we can use explicitly-sized
array parameters instead of pointers in the declarations for the hcall
APIs. When compiled with -Warray-bounds[1], the code above now
provokes a diagnostic like this:
error: array argument is too small;
is of size 32, callee requires at least 72 [-Werror,-Warray-bounds]
60 | plpar_hcall9(H_ALLOCATE_VAS_WINDOW, retbuf,
| ^ ~~~~~~
[1] Enabled for LLVM builds but not GCC for now. See commit
0da6e5fd6c37 ("gcc: disable '-Warray-bounds' for gcc-13 too") and
related changes.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@ellerman.id.au>
[ Upstream commit 03c0f2c2b2220fc9cf8785cd7b61d3e71e24a366 ]
With -Wextra clang warns about pointer arithmetic using a null pointer.
When building with CONFIG_PCI=n, that triggers a warning in the IO
accessors, eg:
In file included from linux/arch/powerpc/include/asm/io.h:672:
linux/arch/powerpc/include/asm/io-defs.h:23:1: warning: performing pointer arithmetic on a null pointer has undefined behavior [-Wnull-pointer-arithmetic]
23 | DEF_PCI_AC_RET(inb, u8, (unsigned long port), (port), pio, port)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...
linux/arch/powerpc/include/asm/io.h:591:53: note: expanded from macro '__do_inb'
591 | #define __do_inb(port) readb((PCI_IO_ADDR)_IO_BASE + port);
| ~~~~~~~~~~~~~~~~~~~~~ ^
That is because when CONFIG_PCI=n, _IO_BASE is defined as 0.
Although _IO_BASE is defined as plain 0, the cast (PCI_IO_ADDR) converts
it to void * before the addition with port happens.
Instead the addition can be done first, and then the cast. The resulting
value will be the same, but avoids the warning, and also avoids void
pointer arithmetic which is apparently non-standard.

------------------
From: Joao Pinto <Joao.Pinto@synopsys.com>
[ Upstream commit 333e11bf47fa8d477db90e2900b1ed3c9ae9b697 ]
I have a use case where nr_buffers = 3 and in which each descriptor is composed by 3
segments, resulting in the DMA channel descs_allocated to be 9. Since axi_desc_put()
handles the hw_desc considering the descs_allocated, this scenario would result in a
kernel panic (hw_desc array will be overrun).
To fix this, the proposal is to add a new member to the axi_dma_desc structure,
where we keep the number of allocated hw_descs (axi_desc_alloc()) and use it in
axi_desc_put() to handle the hw_desc array correctly.
Additionally I propose to remove the axi_chan_start_first_queued() call after completing
the transfer, since it was identified that unbalance can occur (started descriptors can
be interrupted and transfer ignored due to DMA channel not being enabled).

From: Roman Smirnov <r.smirnov@omp.ru>
[ Upstream commit 3b84adf460381169c085e4bc09e7b57e9e16db0a ]
An overflow can occur in a situation where src.centiseconds
takes the value of 255. This situation is unlikely, but there
is no validation check anywere in the code.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@amd.com>
[ Upstream commit 256df20c590bf0e4d63ac69330cf23faddac3e08 ]
Hewlett-Packard HP Pavilion 17 Notebook PC/1972 is an Intel Ivy Bridge
system with a muxless AMD Radeon dGPU. Attempting to use the dGPU fails
with the following sequence:
ACPI Error: Aborting method \AMD3._ON due to previous error (AE_AML_LOOP_TIMEOUT) (20230628/psparse-529)
radeon 0000:01:00.0: not ready 1023ms after resume; waiting
radeon 0000:01:00.0: not ready 2047ms after resume; waiting
radeon 0000:01:00.0: not ready 4095ms after resume; waiting
radeon 0000:01:00.0: not ready 8191ms after resume; waiting
radeon 0000:01:00.0: not ready 16383ms after resume; waiting
radeon 0000:01:00.0: not ready 32767ms after resume; waiting
radeon 0000:01:00.0: not ready 65535ms after resume; giving up
radeon 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
The issue is that the Root Port the dGPU is connected to can't handle the
transition from D3cold to D0 so the dGPU can't properly exit runtime PM.
The existing logic in pci_bridge_d3_possible() checks for systems that are
newer than 2015 to decide that D3 is safe. This would nominally work for
an Ivy Bridge system (which was discontinued in 2015), but this system
appears to have continued to receive BIOS updates until 2017 and so this
existing logic doesn't appropriately capture it.
Add the system to bridge_d3_blacklist to prevent D3cold from being used.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Songyang Li <leesongyang@outlook.com>
[ Upstream commit 29b83a64df3b42c88c0338696feb6fdcd7f1f3b7 ]
The standard PCIe configuration read-write interface is used to
access the configuration space of the peripheral PCIe devices
of the mips processor after the PCIe link surprise down, it can
generate kernel panic caused by "Data bus error". So it is
necessary to add PCIe link status check for system protection.
When the PCIe link is down or in training, assigning a value
of 0 to the configuration address can prevent read-write behavior
to the configuration space of peripheral PCIe devices, thereby
preventing kernel panic.

From: Esben Haabendal <esben@geanix.com>
[ Upstream commit e533e4c62e9993e62e947ae9bbec34e4c7ae81c2 ]
By waiting at most 1 second for USR2_TXDC to be set, we avoid a potential
deadlock.
In case of the timeout, there is not much we can do, so we simply ignore
the transmitter state and optimistically try to continue.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
[ Upstream commit ae9daffd9028f2500c9ac1517e46d4f2b57efb80 ]
read_config_dword() contains strange condition checking ret for a
number of values. The ret variable, however, is always zero because
config_access() never returns anything else. Thus, the retry is always
taken until number of tries is exceeded.
The code looks like it wants to check *val instead of ret to see if the
read gave an error response.

From: Christian Marangi <ansuelsmth@gmail.com>
[ Upstream commit ce5cdd3b05216b704a704f466fb4c2dff3778caf ]
It was discovered that some device have CBR address set to 0 causing
kernel panic when arch_sync_dma_for_cpu_all is called.
This was notice in situation where the system is booted from TP1 and
BMIPS_GET_CBR() returns 0 instead of a valid address and
!!(read_c0_brcm_cmt_local() & (1 << 31)); not failing.
The current check whether RAC flush should be disabled or not are not
enough hence lets check if CBR is a valid address or not.

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
[ Upstream commit 3572bd5689b0812b161b40279e39ca5b66d73e88 ]
The kprobes and synth event generation test modules add events and lock
(get a reference) those event file reference in module init function,
and unlock and delete it in module exit function. This is because those
are designed for playing as modules.
If we make those modules as built-in, those events are left locked in the
kernel, and never be removed. This causes kprobe event self-test failure
as below.

From: Ondrej Mosnacek <omosnace@redhat.com>
[ Upstream commit 9f36169912331fa035d7b73a91252d7c2512eb1a ]
As evident from the definition of ip_options_get(), the IP option
IPOPT_END is used to pad the IP option data array, not IPOPT_NOP. Yet
the loop that walks the IP options to determine the total IP options
length in cipso_v4_delopt() doesn't take IPOPT_END into account.
Fix it by recognizing the IPOPT_END value as the end of actual options.

[ Upstream commit 0b9130247f3b6a1122478471ff0e014ea96bb735 ]
syzbot reported a memory leak in nr_create() [0].
Commit 409db27e3a2e ("netrom: Fix use-after-free of a listening socket.")
added sock_hold() to the nr_heartbeat_expiry() function, where
a) a socket has a SOCK_DESTROY flag or
b) a listening socket has a SOCK_DEAD flag.
But in the case "a," when the SOCK_DESTROY flag is set, the file descriptor
has already been closed and the nr_release() function has been called.
So it makes no sense to hold the reference count because no one will
call another nr_destroy_socket() and put it as in the case "b."
nr_connect
nr_establish_data_link
nr_start_heartbeat
nr_release
switch (nr->state)
case NR_STATE_3
nr->state = NR_STATE_2
sock_set_flag(sk, SOCK_DESTROY);
nr_rx_frame
nr_process_rx_frame
switch (nr->state)
case NR_STATE_2

if (sock_flag(sk, SOCK_DESTROY) ||
(sk->sk_state == TCP_LISTEN
&& sock_flag(sk, SOCK_DEAD)))
sock_hold() // ( !!! )
nr_destroy_socket()
To fix the memory leak, let's call sock_hold() only for a listening socket.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pedro Tammela <pctammela@mojatatu.com>
[ Upstream commit 4b55e86736d5b492cf689125da2600f59c7d2c39 ]
Instead of relying only on the idrinfo->lock mutex for
bind/alloc logic, rely on a combination of rcu + mutex + atomics
to better scale the case where multiple rtnl-less filters are
binding to the same action object.
Action binding happens when an action index is specified explicitly and
an action exists which such index exists. Example:
tc actions add action drop index 1
tc filter add ... matchall action drop index 1
tc filter add ... matchall action drop index 1
tc filter add ... matchall action drop index 1
tc filter ls ...
filter protocol all pref 49150 matchall chain 0 filter protocol all pref 49150 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
filter protocol all pref 49151 matchall chain 0 filter protocol all pref 49151 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
filter protocol all pref 49152 matchall chain 0 filter protocol all pref 49152 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
When no index is specified, as before, grab the mutex and allocate
in the idr the next available id. In this version, as opposed to before,
it's simplified to store the -EBUSY pointer instead of the previous
alloc + replace combination.
When an index is specified, rely on rcu to find if there's an object in
such index. If there's none, fallback to the above, serializing on the
mutex and reserving the specified id. If there's one, it can be an -EBUSY
pointer, in which case we just try again until it's an action, or an action.
Given the rcu guarantees, the action found could be dead and therefore
we need to bump the refcount if it's not 0, handling the case it's
in fact 0.
As bind and the action refcount are already atomics, these increments can
happen without the mutex protection while many tcf_idr_check_alloc race
to bind to the same action instance.
In case binding encounters a parallel delete or add, it will return
-EAGAIN in order to try again. Both filter and action apis already
have the retry machinery in-place. In case it's an unlocked filter it
retries under the rtnl lock.

From: David Ruth <druth@chromium.org>
[ Upstream commit d864319871b05fadd153e0aede4811ca7008f5d6 ]
syzbot found hanging tasks waiting on rtnl_lock [1]
A reproducer is available in the syzbot bug.
When a request to add multiple actions with the same index is sent, the
second request will block forever on the first request. This holds
rtnl_lock, and causes tasks to hang.
Return -EAGAIN to prevent infinite looping, while keeping documented
behavior.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit 2ebe8f840c7450ecbfca9d18ac92e9ce9155e269 ]
As it says in commit 3bc07321ccc2 ("xfrm: Force a dst refcount before
entering the xfrm type handlers"):
"Crypto requests might return asynchronous. In this case we leave the
rcu protected region, so force a refcount on the skb's destination
entry before we enter the xfrm type input/output handlers."
On TIPC decryption path it has the same problem, and skb_dst_force()
should be called before doing decryption to avoid a possible crash.
Shuang reported this issue when this warning is triggered:

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit 88c67aeb14070bab61d3dd8be96c8b42ebcaf53a ]
zones_ht is a global hashtable for flow_table with zone as key. However,
it does not consider netns when getting a flow_table from zones_ht in
tcf_ct_init(), and it means an act_ct action in netns A may get a
flow_table that belongs to netns B if it has the same zone value.
In Shuang's test with the TOPO:
tcf2_c <---> tcf2_sw1 <---> tcf2_sw2 <---> tcf2_s
tcf2_sw1 and tcf2_sw2 saw the same flow and used the same flow table,
which caused their ct entries entering unexpected states and the
TCP connection not able to end normally.
This patch fixes the issue simply by adding netns into the key of
tcf_ct_flow_table so that an act_ct action gets a flow_table that
belongs to its own netns in tcf_ct_init().
Note that for easy coding we don't use tcf_ct_flow_table.nf_ft.net,
as the ct_ft is initialized after inserting it to the hashtable in
tcf_ct_flow_table_get() and also it requires to implement several
functions in rhashtable_params including hashfn, obj_hashfn and
obj_cmpfn.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heng Qi <hengqi@linux.alibaba.com>
[ Upstream commit 604141c036e1b636e2a71cf6e1aa09d1e45f40c2 ]
In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Simon Horman <horms@kernel.org>
[ Upstream commit b95a4afe2defd6f46891985f9436a568cd35a31c ]
otx2_sq_append_skb makes used of __vlan_hwaccel_push_inside()
to unoffload VLANs - push them from skb meta data into skb data.
However, it omitts a check for __vlan_hwaccel_push_inside()
returning NULL.
Found by inspection based on [1] and [2].
Compile tested only.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jozsef Kadlecsik <kadlec@netfilter.org>
[ Upstream commit 8ecd06277a7664f4ef018abae3abd3451d64e7a6 ]
When destroying all sets, we are either in pernet exit phase or
are executing a "destroy all sets command" from userspace. The latter
was taken into account in ip_set_dereference() (nfnetlink mutex is held),
but the former was not. The patch adds the required check to
rcu_dereference_protected() in ip_set_dereference().

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pavan Chebbi <pavan.chebbi@broadcom.com>
[ Upstream commit 1e7962114c10957fe4d10a15eb714578a394e90b ]
The current code only restores PTP tx_avail count when we get DMA
mapping errors. Fix it so that the PTP tx_avail count will be
restored for both DMA mapping errors and skb_pad() errors.
Otherwise PTP TX timestamp will not be available after a PTP
packet hits the skb_pad() error.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li RongQing <lirongqing@baidu.com>
[ Upstream commit e3215deca4520773cd2b155bed164c12365149a7 ]
Use list_for_each_entry_safe() to allow iterating through the list and
deleting the entry in the iteration process. The descriptor is freed via
idxd_desc_complete() and there's a slight chance may cause issue for
the list iterator when the descriptor is reused by another thread
without it being deleted from the list.

From: Qing Wang <wangqing@vivo.com>
[ Upstream commit 0c5afef7bf1fbda7e7883dc4b93f64f90003706f ]
The wrappers in include/linux/pci-dma-compat.h should go away.
pci_set_dma_mask()/pci_set_consistent_dma_mask() should be
replaced with dma_set_mask()/dma_set_coherent_mask(),
and use dma_set_mask_and_coherent() for both.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Helgaas <bhelgaas@google.com>
[ Upstream commit e32622f84ae289dc7a04e9f01cd62cb914fdc5c6 ]
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

The PCIe Capability is defined by the PCIe spec, so use the PCI_EXP_DEVCTL
macros defined by the PCI core instead of defining copies in IOAT. This
makes it easier to find all uses of the PCIe Device Control register. No
functional change intended.

From: Raju Rangoju <Raju.Rangoju@amd.com>
[ Upstream commit a83e1385b780d41307433ddbc86e3c528db031f0 ]
Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid
"Info: mapping multiple BARs. Your kernel is fine.""). The initial
purpose of this commit was to stop memory mappings for operation
regions from overlapping page boundaries, as it can trigger warnings
if different page attributes are present.
However, it was found that when this situation arises, mapping
continues until the boundary's end, but there is still an attempt to
read/write the entire length of the map, leading to a NULL pointer
deference. For example, if a four-byte mapping request is made but
only one byte is mapped because it hits the current page boundary's
end, a four-byte read/write attempt is still made, resulting in a NULL
pointer deference.
Instead, map the entire length, as the ACPI specification does not
mandate that it must be within the same page boundary. It is
permissible for it to be mapped across different regions.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Erwan Le Ray <erwan.leray@foss.st.com>
commit 33bb2f6ac3088936b7aad3cab6f439f91af0223c upstream.
This patch reworks RX support over DMA to improve reliability:
- change dma buffer cyclic configuration by using 2 periods. DMA buffer
data are handled by a flip-flop between the 2 periods in order to avoid
risk of data loss/corruption
- change the size of dma buffer to 4096 to limit overruns
- add rx errors management (breaks, parity, framing and overrun).
When an error occurs on the uart line, the dma request line is masked at
HW level. The SW must 1st clear DMAR (dma request line enable), to
handle the error, then re-enable DMAR to recover. So, any correct data
is taken from the DMA buffer, before handling the error itself. Then
errors are handled from RDR/ISR/FIFO (e.g. in PIO mode). Last, DMA
reception is resumed.
- add a condition on DMA request line in DMA RX routines in order to
switch to PIO mode when no DMA request line is disabled, even if the DMA
channel is still enabled.
When the UART is wakeup source and is configured to use DMA for RX, any
incoming data that wakes up the system isn't correctly received.
At data reception, the irq_handler handles the WUF irq, and then the
data reception over DMA.
As the DMA transfer has been terminated at suspend, and will be restored
by resume callback (which has no yet been called by system), the data
can't be received.
The wake-up data has to be handled in PIO mode while suspend callback
has not been called.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ignat Korchagin <ignat@cloudflare.com>
commit 6cd4a78d962bebbaf8beb7d2ead3f34120e3f7b2 upstream.
It is possible to trigger a use-after-free by:
* attaching an fentry probe to __sock_release() and the probe calling the
bpf_get_socket_cookie() helper
* running traceroute -I 1.1.1.1 on a freshly booted VM
A KASAN enabled kernel will log something like below (decoded and stripped):

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Burkov <boris@bur.io>
commit 4eb4e85c4f818491efc67e9373aa16b123c3f522 upstream.
If inc_block_group_ro systematically fails (e.g. due to ETXTBUSY from
swap) or btrfs_relocate_chunk systematically fails (from lack of
space), then this worker becomes an infinite loop.
At the very least, this strands the cleaner thread, but can also result
in hung tasks/RCU stalls on PREEMPT_NONE kernels and if the
reclaim_bgs_lock mutex is not contended.
I believe the best long term fix is to manage reclaim via work queue,
where we queue up a relocation on the triggering condition and re-queue
on failure. In the meantime, this is an easy fix to apply to avoid the
immediate pain.
Fixes: 7e2718099438 ("btrfs: reinsert BGs failed to reclaim")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Christopherson <seanjc@google.com>
commit f3ced000a2df53f4b12849e121769045a81a3b22 upstream.
Sync pending posted interrupts to the IRR prior to re-scanning I/O APIC
routes, irrespective of whether the I/O APIC is emulated by userspace or
by KVM. If a level-triggered interrupt routed through the I/O APIC is
pending or in-service for a vCPU, KVM needs to intercept EOIs on said
vCPU even if the vCPU isn't the destination for the new routing, e.g. if
servicing an interrupt using the old routing races with I/O APIC
reconfiguration.
Commit fceb3a36c29a ("KVM: x86: ioapic: Fix level-triggered EOI and
userspace I/OAPIC reconfigure race") fixed the common cases, but
kvm_apic_pending_eoi() only checks if an interrupt is in the local
APIC's IRR or ISR, i.e. misses the uncommon case where an interrupt is
pending in the PIR.
Failure to intercept EOI can manifest as guest hangs with Windows 11 if
the guest uses the RTC as its timekeeping source, e.g. if the VMM doesn't
expose a more modern form of time to the guest.

From: Edson Juliano Drosdeck <edson.drosdeck@gmail.com>
commit 86a433862912f52597263aa224a9ed82bcd533bf upstream.
The internal mic boost on the N14AP7 is too high. Fix this by applying the
ALC269_FIXUP_LIMIT_INT_MIC_BOOST fixup to the machine to limit the gain.

From: Jani Nikula <jani.nikula@intel.com>
commit 49cc17967be95d64606d5684416ee51eec35e84a upstream.
It's not possible to use the joiner at the same time with eDP MSO. When
a panel needs MSO, it's not optional, so MSO trumps joiner.
v3: Only change intel_dp_has_joiner(), leave debugfs alone (Ville)

commit c1558bc57b8e5b4da5d821537cd30e2e660861d8 upstream.
Using gcov on kernels compiled with GCC 14 results in truncated 16-byte
long .gcda files with no usable data. To fix this, update GCOV_COUNTERS
to match the value defined by GCC 14.
Tested with GCC versions 14.1.0 and 13.2.0.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aleksandr Nogikh <nogikh@google.com>
commit 01c8f9806bde438ca1c8cbbc439f0a14a6694f6c upstream.
In kcov_remote_start()/kcov_remote_stop(), we swap the previous KCOV
metadata of the current task into a per-CPU variable. However, the
kcov_mode_enabled(mode) check is not sufficient in the case of remote KCOV
coverage: current->kcov_mode always remains KCOV_MODE_DISABLED for remote
KCOV objects.
If the original task that has invoked the KCOV_REMOTE_ENABLE ioctl happens
to get interrupted and kcov_remote_start() is called, it ultimately leads
to kcov_remote_stop() NOT restoring the original KCOV reference. So when
the task exits, all registered remote KCOV handles remain active forever.
The most uncomfortable effect (at least for syzkaller) is that the bug
prevents the reuse of the same /sys/kernel/debug/kcov descriptor. If
we obtain it in the parent process and then e.g. drop some
capabilities and continuously fork to execute individual programs, at
some point current->kcov of the forked process is lost,
kcov_task_exit() takes no action, and all KCOV_REMOTE_ENABLE ioctls
calls from subsequent forks fail.
And, yes, the efficiency is also affected if we keep on losing remote
kcov objects.
a) kcov_remote_map keeps on growing forever.
b) (If I'm not mistaken), we're also not freeing the memory referenced
by kcov->area.
Fix it by introducing a special kcov_mode that is assigned to the task
that owns a KCOV remote object. It makes kcov_mode_enabled() return true
and yet does not trigger coverage collection in __sanitizer_cov_trace_pc()
and write_comp_data().

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
commit 9e046bb111f13461d3f9331e24e974324245140e upstream.
Some applications were reporting ETIMEDOUT errors on apparently
good looking flows, according to packet dumps.
We were able to root cause the issue to an accidental setting
of tp->retrans_stamp in the following scenario:
- client sends TFO SYN with data.
- server has TFO disabled, ACKs only SYN but not payload.
- client receives SYNACK covering only SYN.
- tcp_ack() eats SYN and sets tp->retrans_stamp to 0.
- tcp_rcv_fastopen_synack() calls tcp_xmit_retransmit_queue()
to retransmit TFO payload w/o SYN, sets tp->retrans_stamp to "now",
but we are not in any loss recovery state.
- TFO payload is ACKed.
- we are not in any loss recovery state, and don't see any dupacks,
so we don't get to any code path that clears tp->retrans_stamp.
- tp->retrans_stamp stays non-zero for the lifetime of the connection.
- after first RTO, tcp_clamp_rto_to_user_timeout() clamps second RTO
to 1 jiffy due to bogus tp->retrans_stamp.
- on clamped RTO with non-zero icsk_retransmits, retransmits_timed_out()
sets start_ts from tp->retrans_stamp from TFO payload retransmit
hours/days ago, and computes bogus long elapsed time for loss recovery,
and suffers ETIMEDOUT early.

commit 5a72477273066b5b357801ab2d315ef14949d402 upstream.
Setting IACK bit when core is disabled does not clear the "Interrupt Flag"
bit in the status register, and the interrupt remains pending.
Sometimes it causes failure for the very first message transfer, that is
usually a device probe.
Hence, set IACK bit after core is enabled to clear pending interrupt.

------------------
From: Adrian Hunter <adrian.hunter@intel.com>
[ Upstream commit d4a98b45fbe6d06f4b79ed90d0bb05ced8674c23 ]
The trace could be misleading if trace errors are not taken into
account, so display them also by adding the itrace "e" option.
Note --call-trace and --call-ret-trace already add the itrace "e"
option.

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit 87d8e522d6f5a004f0aa06c0def302df65aff296 ]
Although the Samsung SoC keypad binding defined
linux,keypad-no-autorepeat property, Linux driver never implemented it
and always used linux,input-no-autorepeat. Correct the DTS to use
property actually implemented.

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit 4ac4c1d794e7ff454d191bbdab7585ed8dbf3758 ]
Although the Samsung SoC keypad binding defined
linux,keypad-no-autorepeat property, Linux driver never implemented it
and always used linux,input-no-autorepeat. Correct the DTS to use
property actually implemented.
This also fixes dtbs_check errors like:
exynos4412-smdk4412.dtb: keypad@100a0000: 'key-A', 'key-B', 'key-C', 'key-D', 'key-E', 'linux,keypad-no-autorepeat' do not match any of the regexes: '^key-[0-9a-z]+$', 'pinctrl-[0-9]+'

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bitterblue Smith <rtl8821cerfe2@gmail.com>
[ Upstream commit de4d4be4fa64ed7b4aa1c613061015bd8fa98b24 ]
Different channels have different TX power settings. rtl8192de is using
the TX power setting from the wrong channel in the 5 GHz band because
_rtl92c_phy_get_rightchnlplace expects an array which includes all the
channel numbers, but it's using an array which includes only the 5 GHz
channel numbers.
Use the array channel_all (defined in rtl8192de/phy.c) instead of
the incorrect channel5g (defined in core.c).
Tested only with rtl8192du, which will use the same TX power code.

[ Upstream commit 670c900f69645db394efb38934b3344d8804171a ]
When the dts file has multiple referrers to a single PD (e.g.
simple-framebuffer and dss nodes both point to the DSS power-domain) the
ti-sci driver will create two power domains, both with the same ID, and
that will cause problems as one of the power domains will hide the other
one.
Fix this checking if a PD with the ID has already been created, and only
create a PD for new IDs.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Mirvish <matthew@mm12.xyz>
[ Upstream commit 3a861560ccb35f2a4f0a4b8207fa7c2a35fc7f31 ]
btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.
This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length
data array.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tony Luck <tony.luck@intel.com>
[ Upstream commit 93022482b2948a9a7e9b5a2bb685f2e1cb4c3348 ]
Code in v6.9 arch/x86/kernel/smpboot.c was changed by commit
4db64279bc2b ("x86/cpu: Switch to new Intel CPU model defines") from:
static const struct x86_cpu_id intel_cod_cpu[] = {
X86_MATCH_INTEL_FAM6_MODEL(HASWELL_X, 0), /* COD */
X86_MATCH_INTEL_FAM6_MODEL(BROADWELL_X, 0), /* COD */
X86_MATCH_INTEL_FAM6_MODEL(ANY, 1), /* SNC */ <--- 443
{}
};
static bool match_llc(struct cpuinfo_x86 *c, struct cpuinfo_x86 *o)
{
const struct x86_cpu_id *id = x86_match_cpu(intel_cod_cpu);
to:
static const struct x86_cpu_id intel_cod_cpu[] = {
X86_MATCH_VFM(INTEL_HASWELL_X, 0), /* COD */
X86_MATCH_VFM(INTEL_BROADWELL_X, 0), /* COD */
X86_MATCH_VFM(INTEL_ANY, 1), /* SNC */
{}
};
static bool match_llc(struct cpuinfo_x86 *c, struct cpuinfo_x86 *o)
{
const struct x86_cpu_id *id = x86_match_cpu(intel_cod_cpu);
On an Intel CPU with SNC enabled this code previously matched the rule on line
443 to avoid printing messages about insane cache configuration. The new code
did not match any rules.
Expanding the macros for the intel_cod_cpu[] array shows that the old is
equivalent to:
static const struct x86_cpu_id intel_cod_cpu[] = {
[0] = { .vendor = 0, .family = 6, .model = 0x3F, .steppings = 0, .feature = 0, .driver_data = 0 },
[1] = { .vendor = 0, .family = 6, .model = 0x4F, .steppings = 0, .feature = 0, .driver_data = 0 },
[2] = { .vendor = 0, .family = 6, .model = 0x00, .steppings = 0, .feature = 0, .driver_data = 1 },
[3] = { .vendor = 0, .family = 0, .model = 0x00, .steppings = 0, .feature = 0, .driver_data = 0 }
}
while the new code expands to:
static const struct x86_cpu_id intel_cod_cpu[] = {
[0] = { .vendor = 0, .family = 6, .model = 0x3F, .steppings = 0, .feature = 0, .driver_data = 0 },
[1] = { .vendor = 0, .family = 6, .model = 0x4F, .steppings = 0, .feature = 0, .driver_data = 0 },
[2] = { .vendor = 0, .family = 0, .model = 0x00, .steppings = 0, .feature = 0, .driver_data = 1 },
[3] = { .vendor = 0, .family = 0, .model = 0x00, .steppings = 0, .feature = 0, .driver_data = 0 }
}
Looking at the code for x86_match_cpu():
const struct x86_cpu_id *x86_match_cpu(const struct x86_cpu_id *match)
{
const struct x86_cpu_id *m;
struct cpuinfo_x86 *c = &boot_cpu_data;
for (m = match;
m->vendor | m->family | m->model | m->steppings | m->feature;
m++) {
...
}
return NULL;
it is clear that there was no match because the ANY entry in the table (array
index 2) is now the loop termination condition (all of vendor, family, model,
steppings, and feature are zero).
So this code was working before because the "ANY" check was looking for any
Intel CPU in family 6. But fails now because the family is a wild card. So the
root cause is that x86_match_cpu() has never been able to match on a rule with
just X86_VENDOR_INTEL and all other fields set to wildcards.
Add a new flags field to struct x86_cpu_id that has a bit set to indicate that
this entry in the array is valid. Update X86_MATCH*() macros to set that bit.
Change the end-marker check in x86_match_cpu() to just check the flags field
for this bit.
Backporter notes: The commit in Fixes is really the one that is broken:
you can't have m->vendor as part of the loop termination conditional in
x86_match_cpu() because it can happen - as it has happened above
- that that whole conditional is 0 albeit vendor == 0 is a valid case
- X86_VENDOR_INTEL is 0.
However, the only case where the above happens is the SNC check added by
4db64279bc2b1 so you only need this fix if you have backported that
other commit
4db64279bc2b ("x86/cpu: Switch to new Intel CPU model defines")
Fixes: 644e9cbbe3fc ("Add driver auto probing for x86 features v4")

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Wilson <chris@chris-wilson.co.uk>
[ Upstream commit c877bed82e1017c102c137d432933ccbba92c119 ]
One impact of commit 047a1b877ed4 ("dma-buf & drm/amdgpu: remove
dma_resv workaround") is that it stores many, many more fences. Whereas
adding an exclusive fence used to remove the shared fence list, that
list is now preserved and the write fences included into the list. Not
just a single write fence, but now a write/read fence per context. That
causes us to have to track more fences than before (albeit half of those
are redundant), and we trigger more interrupts for multi-engine
workloads.
As part of reducing the impact from handling more signaling, we observe
we only need to kick the signal worker after adding a fence iff we have
good cause to believe that there is work to be done in processing the
fence i.e. we either need to enable the interrupt or the request is
already complete but we don't know if we saw the interrupt and so need
to check signaling.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Wilson <chris@chris-wilson.co.uk>
[ Upstream commit 70cb9188ffc75e643debf292fcddff36c9dbd4ae ]
The breadcrumbs use a GT wakeref for guarding the interrupt, but are
disarmed during release of the engine wakeref. This leaves a hole where
we may attach a breadcrumb just as the engine is parking (after it has
parked its breadcrumbs), execute the irq worker with some signalers still
attached, but never be woken again.
That issue manifests itself in CI with IGT runner timeouts while tests
are waiting indefinitely for release of all GT wakerefs.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit 49c386ebbb43394ff4773ce24f726f6afc4c30c8 ]
This reverts commit 700dea5a0bea9f64eba89fae7cb2540326fdfdc1.
The reason for that commit was --sort=ORDER introduced in
tar 1.28 (2014). More than 3 years have passed since then.
Requiring GNU tar 1.28 should be fine now because we require
GCC 5.1 (2015).

[ Upstream commit 3bd27a847a3a4827a948387cc8f0dbc9fa5931d5 ]
Build environments might be running with different umask settings
resulting in indeterministic file modes for the files contained in
kheaders.tar.xz. The file itself is served with 444, i.e. world
readable. Archive the files explicitly with 744,a+X to improve
reproducibility across build environments.
--mode=0444 is not suitable as directories need to be executable. Also,
444 makes it hard to delete all the readonly files after extraction.

From: Jisheng Zhang <jszhang@kernel.org>
[ Upstream commit 07aabe8fb6d1ac3163cc74c856521f2ee746270b ]
Try our best to replace the conditional compilation using
"#ifdef CONFIG_64BIT" by a check for "IS_ENABLED(CONFIG_64BIT)", to
simplify the code and to increase compile coverage.
Now we can also remove the __maybe_unused used in max_mapped_addr
declaration.
We also remove the BUG_ON check of mapping the last 4K bytes of the
addressable memory since this is always true for every kernel actually.

From: Nam Cao <namcao@linutronix.de>
[ Upstream commit 994af1825a2aa286f4903ff64a1c7378b52defe6 ]
On riscv32, it is possible for the last page in virtual address space
(0xfffff000) to be allocated. This page overlaps with PTR_ERR, so that
shouldn't happen.
There is already some code to ensure memblock won't allocate the last page.
However, buddy allocator is left unchecked.
Fix this by reserving physical memory that would be mapped at virtual
addresses greater than 0xfffff000.

The task was waiting for the refcount become to 1, but from the vmcore,
we found the refcount has already been 1. It seems that the task didn't
get woken up by perf_event_release_kernel() and got stuck forever. The
below scenario may cause the problem.
Thread A Thread B
... ...
perf_event_free_task perf_event_release_kernel
...
acquire event->child_mutex
...
get_ctx
... release event->child_mutex
acquire ctx->mutex
...
perf_free_event (acquire/release event->child_mutex)
...
release ctx->mutex
wait_var_event
acquire ctx->mutex
acquire event->child_mutex
# move existing events to free_list
release event->child_mutex
release ctx->mutex
put_ctx
... ...
In this case, all events of the ctx have been freed, so we couldn't
find the ctx in free_list and Thread A will miss the wakeup. It's thus
necessary to add a wakeup after dropping the reference.

From: Naveen Naidu <naveennaidu479@gmail.com>
[ Upstream commit 57bdeef4716689d9b0e3571034d65cf420f6efcd ]
A config or MMIO read from a PCI device that doesn't exist or doesn't
respond causes a PCI error. There's no real data to return to satisfy the
CPU read, so most hardware fabricates ~0 data.
Add a PCI_ERROR_RESPONSE definition for that and use it where appropriate
to make these checks consistent and easier to find.
Also add helper definitions PCI_SET_ERROR_RESPONSE() and
PCI_POSSIBLE_ERROR() to make the code more readable.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yazen Ghannam <yazen.ghannam@amd.com>
[ Upstream commit c625dabbf1c4a8e77e4734014f2fde7aa9071a1f ]
AMD Zen-based systems use a System Management Network (SMN) that
provides access to implementation-specific registers.
SMN accesses are done indirectly through an index/data pair in PCI
config space. The PCI config access may fail and return an error code.
This would prevent the "read" value from being updated.
However, the PCI config access may succeed, but the return value may be
invalid. This is in similar fashion to PCI bad reads, i.e. return all
bits set.
Most systems will return 0 for SMN addresses that are not accessible.
This is in line with AMD convention that unavailable registers are
Read-as-Zero/Writes-Ignored.
However, some systems will return a "PCI Error Response" instead. This
value, along with an error code of 0 from the PCI config access, will
confuse callers of the amd_smn_read() function.
Check for this condition, clear the return value, and set a proper error
code.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@amd.com>
[ Upstream commit 10b6b4a8ac6120ec36555fd286eed577f7632e3b ]
Picasso was the first APU that introduced s2idle support from AMD,
and it was predating before vendors started to use `StorageD3Enable`
in their firmware.
Windows doesn't have problems with this hardware and NVME so it was
likely on the list of hardcoded CPUs to use this behavior in Windows.
Add it to the list for Linux to avoid NVME resume issues.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@amd.com>
[ Upstream commit e79a10652bbd320649da705ca1ea0c04351af403 ]
A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.
This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.
As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.
This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ziwei Xiao <ziweixiao@google.com>
[ Upstream commit 6f4d93b78ade0a4c2cafd587f7b429ce95abb02e ]
gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it
is freed with dev_kfree_skb_any(). This can result in a subsequent call
to napi_get_frags returning a dangling pointer.
Fix this by clearing napi->skb before the skb is freed.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hagar Hemdan <hagarhem@amazon.com>
[ Upstream commit adec57ff8e66aee632f3dd1f93787c13d112b7a1 ]
In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.
This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

From: Huang-Huang Bao <i@eh5.me>
[ Upstream commit e8448a6c817c2aa6c6af785b1d45678bd5977e8d ]
The pinmux bits for GPIO2-B0 to GPIO2-B6 actually have 2 bits width,
correct the bank flag for GPIO2-B. The pinmux bits for GPIO2-B7 is
recalculated so it remain unchanged.
The pinmux bits for those pins are not explicitly specified in RK3328
TRM, however we can get hint from pad name and its correspinding IOMUX
setting for pins in interface descriptions. The correspinding IOMIX
settings for GPIO2-B0 to GPIO2-B6 can be found in the same row next to
occurrences of following pad names in RK3328 TRM.
GPIO2-B0: IO_SPIclkm0_GPIO2B0vccio5
GPIO2-B1: IO_SPItxdm0_GPIO2B1vccio5
GPIO2-B2: IO_SPIrxdm0_GPIO2B2vccio5

GPIO2-B5: IO_ I2C2sda_TSADCshut_GPIO2B5vccio5
GPIO2-B6: IO_ I2C2scl_GPIO2B6vccio5
This fix has been tested on NanoPi R2S for fixing confliting pinmux bits
between GPIO2-B7 with GPIO2-B5.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Huang-Huang Bao <i@eh5.me>
[ Upstream commit 01b4b1d1cec48ef4c26616c2fc4600b2c9fec05a ]
rk3328_pin_ctrl uses type of RK3288 which has a hack in
rockchip_pinctrl_suspend and rockchip_pinctrl_resume to restore GPIO6-C6
at assume, the hack is not applicable to RK3328 as GPIO6 is not even
exist in it. So use a dedicated pinctrl type to skip this hack.

From: Elinor Montmasson <elinor.montmasson@savoirfairelinux.com>
[ Upstream commit 90f3feb24172185f1832636264943e8b5e289245 ]
priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.

From: Tristram Ha <tristram.ha@microchip.com>
[ Upstream commit ad53f5f54f351e967128edbc431f0f26427172cf ]
The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nick Child <nnac123@linux.ibm.com>
[ Upstream commit 49bbeb5719c2f56907d3a9623b47c6c15c2c431d ]
There are 2 types of outstanding tx skb's:
Type 1: Packets that are sitting in the drivers ind_buff that are
waiting to be batch sent to the NIC. During a device reset, these are
freed with a call to ibmvnic_tx_scrq_clean_buffer()
Type 2: Packets that have been sent to the NIC and are awaiting a TX
completion IRQ. These are free'd during a reset with a call to
clean_tx_pools()
During any reset which requires us to free the tx irq, ensure that the
Type 2 skb references are freed. Since the irq is released, it is
impossible for the NIC to inform of any completions.
Furthermore, later in the reset process is a call to init_tx_pools()
which marks every entry in the tx pool as free (ie not outstanding).
So if the driver is to make a call to init_tx_pools(), it must first
be sure that the tx pool is empty of skb references.
This issue was discovered by observing the following in the logs during
EEH testing:
TX free map points to untracked skb (tso_pool 0 idx=4)
TX free map points to untracked skb (tso_pool 0 idx=5)
TX free map points to untracked skb (tso_pool 1 idx=36)

[ Upstream commit 7e9f79428372c6eab92271390851be34ab26bfb4 ]
syzkaller reports a warning in __xdp_reg_mem_model().
The warning occurs only if __mem_id_init_hash_table() returns an error. It
returns the error in two cases:
1. memory allocation fails;
2. rhashtable_init() fails when some fields of rhashtable_params
struct are not initialized properly.
The second case cannot happen since there is a static const rhashtable_params
struct with valid fields. So, warning is only triggered when there is a
problem with memory allocation.
Thus, there is no sense in using WARN() to handle this error and it can be
safely removed.

From: Akhmat Karakotov <hmukos@yandex-team.ru>
[ Upstream commit 5903123f662ed18483f05cac3f9e800a074c29ff ]
When setting RTO through BPF program, some SYN ACK packets were unaffected
and continued to use TCP_TIMEOUT_INIT constant. This patch adds timeout
option to struct request_sock. Option is initialized with TCP_TIMEOUT_INIT
and is reassigned through BPF using tcp_timeout_init call. SYN ACK
retransmits now use newly added timeout option.

Acked-by: Martin KaFai Lau <kafai@fb.com>
v2:
- Add timeout option to struct request_sock. Do not call
tcp_timeout_init on every syn ack retransmit.
v3:
- Use unsigned long for min. Bound tcp_timeout_init to TCP_RTO_MAX.
v4: - Refactor duplicate code by adding reqsk_timeout function.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: luoxuanqiang <luoxuanqiang@kylinos.cn>
[ Upstream commit ff46e3b4421923937b7f6e44ffcd3549a074f321 ]
When bonding is configured in BOND_MODE_BROADCAST mode, if two identical
SYN packets are received at the same time and processed on different CPUs,
it can potentially create the same sk (sock) but two different reqsk
(request_sock) in tcp_conn_request().
These two different reqsk will respond with two SYNACK packets, and since
the generation of the seq (ISN) incorporates a timestamp, the final two
SYNACK packets will have different seq values.
The consequence is that when the Client receives and replies with an ACK
to the earlier SYNACK packet, we will reset(RST) it.
========================================================================
This behavior is consistently reproducible in my local setup,
which comprises:
| NETA1 ------ NETB1 |
PC_A --- bond --- | | --- bond --- PC_B
| NETA2 ------ NETB2 |
- PC_A is the Server and has two network cards, NETA1 and NETA2. I have
bonded these two cards using BOND_MODE_BROADCAST mode and configured
them to be handled by different CPU.
- PC_B is the Client, also equipped with two network cards, NETB1 and
NETB2, which are also bonded and configured in BOND_MODE_BROADCAST mode.
If the client attempts a TCP connection to the server, it might encounter
a failure. Capturing packets from the server side reveals:
10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
localhost > 10.10.10.10.45182: Flags [S.], seq 2967855116,
localhost > 10.10.10.10.45182: Flags [S.], seq 2967855123, <==
10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
localhost > 10.10.10.10.45182: Flags [R], seq 2967855117, <==
localhost > 10.10.10.10.45182: Flags [R], seq 2967855117,
Two SYNACKs with different seq numbers are sent by localhost,
resulting in an anomaly.
========================================================================
The attempted solution is as follows:
Add a return value to inet_csk_reqsk_queue_hash_add() to confirm if the
ehash insertion is successful (Up to now, the reason for unsuccessful
insertion is that a reqsk for the same connection has already been
inserted). If the insertion fails, release the reqsk.
Due to the refcnt, Kuniyuki suggests also adding a return value check
for the DCCP module; if ehash insertion fails, indicating a successful
insertion of the same connection, simply release the reqsk as well.
Simultaneously, In the reqsk_queue_hash_req(), the start of the
req->rsk_timer is adjusted to be after successful insertion.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit bae6428a9fffb2023191b0723e276cf1377a7c9f ]
sparc has two identical select syscalls at numbers 93 and 230, respectively.
During the conversion to the modern syscall.tbl format, the older one of the
two broke in compat mode, and now refers to the native 64-bit syscall.
Restore the correct behavior. This has very little effect, as glibc has
been using the newer number anyway.

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit d6fbd26fb872ec518d25433a12e8ce8163e20909 ]
sparc has the wrong compat version of recv() and recvfrom() for both the
direct syscalls and socketcall().
The direct syscalls just need to use the compat version. For socketcall,
the same thing could be done, but it seems better to completely remove
the custom assembler code for it and just use the same implementation that
everyone else has.

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 20a50787349fadf66ac5c48f62e58d753878d2bb ]
Johannes missed parisc back when he introduced the compat version
of these syscalls, so receiving cmsg messages that require a compat
conversion is still broken.
Use the correct calls like the other architectures do.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Neal Cardwell <ncardwell@google.com>
[ Upstream commit 5dfe9d273932c647bdc9d664f939af9a5a398cbc ]
Testing determined that the recent commit 9e046bb111f1 ("tcp: clear
tp->retrans_stamp in tcp_rcv_fastopen_synack()") has a race, and does
not always ensure retrans_stamp is 0 after a TFO payload retransmit.
If transmit completion for the SYN+data skb happens after the client
TCP stack receives the SYNACK (which sometimes happens), then
retrans_stamp can erroneously remain non-zero for the lifetime of the
connection, causing a premature ETIMEDOUT later.
Testing and tracing showed that the buggy scenario is the following
somewhat tricky sequence:
+ Client attempts a TFO handshake. tcp_send_syn_data() sends SYN + TFO
cookie + data in a single packet in the syn_data skb. It hands the
syn_data skb to tcp_transmit_skb(), which makes a clone. Crucially,
it then reuses the same original (non-clone) syn_data skb,
transforming it by advancing the seq by one byte and removing the
FIN bit, and enques the resulting payload-only skb in the
sk->tcp_rtx_queue.
+ Client sets retrans_stamp to the start time of the three-way
handshake.
+ Cookie mismatches or server has TFO disabled, and server only ACKs
SYN.
+ tcp_ack() sees SYN is acked, tcp_clean_rtx_queue() clears
retrans_stamp.
+ Since the client SYN was acked but not the payload, the TFO failure
code path in tcp_rcv_fastopen_synack() tries to retransmit the
payload skb. However, in some cases the transmit completion for the
clone of the syn_data (which had SYN + TFO cookie + data) hasn't
happened. In those cases, skb_still_in_host_queue() returns true
for the retransmitted TFO payload, because the clone of the syn_data
skb has not had its tx completetion.
+ Because skb_still_in_host_queue() finds skb_fclone_busy() is true,
it sets the TSQ_THROTTLED bit and the retransmit does not happen in
the tcp_rcv_fastopen_synack() call chain.
+ The tcp_rcv_fastopen_synack() code next implicitly assumes the
retransmit process is finished, and sets retrans_stamp to 0 to clear
it, but this is later overwritten (see below).
+ Later, upon tx completion, tcp_tsq_write() calls
tcp_xmit_retransmit_queue(), which puts the retransmit in flight and
sets retrans_stamp to a non-zero value.
+ The client receives an ACK for the retransmitted TFO payload data.
+ Since we're in CA_Open and there are no dupacks/SACKs/DSACKs/ECN to
make tcp_ack_is_dubious() true and make us call
tcp_fastretrans_alert() and reach a code path that clears
retrans_stamp, retrans_stamp stays nonzero.
+ Later, if there is a TLP, RTO, RTO sequence, then the connection
will suffer an early ETIMEDOUT due to the erroneously ancient
retrans_stamp.
The fix: this commit refactors the code to have
tcp_rcv_fastopen_synack() retransmit by reusing the relevant parts of
tcp_simple_retransmit() that enter CA_Loss (without changing cwnd) and
call tcp_xmit_retransmit_queue(). We have tcp_simple_retransmit() and
tcp_rcv_fastopen_synack() share code in this way because in both cases
we get a packet indicating non-congestion loss (MTU reduction or TFO
failure) and thus in both cases we want to retransmit as many packets
as cwnd allows, without reducing cwnd. And given that retransmits will
set retrans_stamp to a non-zero value (and may do so in a later
calling context due to TSQ), we also want to enter CA_Loss so that we
track when all retransmitted packets are ACked and clear retrans_stamp
when that happens (to ensure later recurring RTOs are using the
correct retrans_stamp and don't declare ETIMEDOUT prematurely).
Fixes: 9e046bb111f1 ("tcp: clear tp->retrans_stamp in tcp_rcv_fastopen_synack()")
Fixes: a7abf3cd76e1 ("tcp: consider using standard rtx logic in tcp_rcv_fastopen_synack()")

From: Pablo Neira Ayuso <pablo@netfilter.org>
[ Upstream commit 7931d32955e09d0a11b1fe0b6aac1bfa061c005c ]
register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yunseong Kim <yskelg@gmail.com>
[ Upstream commit bab4923132feb3e439ae45962979c5d9d5c7c1f1 ]
In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from
qdisc->dev_queue->dev <NULL> ->name
This situation simulated from bunch of veths and Bluetooth disconnection
and reconnection.
During qdisc initialization, qdisc was being set to noop_queue.
In veth_init_queue, the initial tx_num was reduced back to one,
causing the qdisc reset to be called with noop, which led to the kernel
panic.
I've attached the GitHub gist link that C converted syz-execprogram
source code and 3 log of reproduced vmcore-dmesg.
https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740
Yeoreum and I use two fuzzing tool simultaneously.
One process with syz-executor : https://github.com/google/syzkaller
$ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
-enable=none -collide=false log1
The other process with perf fuzzer:
https://github.com/deater/perf_event_tests/tree/master/fuzzer
$ perf_event_tests/fuzzer/perf_fuzzer
I think this will happen on the kernel version.
Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.
This occurred from 51270d573a8d. I think this patch is absolutely
necessary. Previously, It was showing not intended string value of name.
I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
or patched.

[ 5301.597057] Bye!
After applying our patch, I didn't find any kernel panic errors.
We've found a simple reproducer
# echo 1 > /sys/kernel/debug/tracing/events/qdisc/qdisc_reset/enable
# ip link add veth0 type veth peer name veth1
Error: Unknown device type.
However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
using the qdisc_reset event and the ip command on my qemu virtual machine.
This 2 commands makes always kernel panic.

Yeoreum and I don't know if the patch we wrote will fix the underlying
cause, but we think that priority is to prevent kernel panic happening.
So, we're sending this patch.

------------------
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
[ Upstream commit ee7860cd8b5763017f8dc785c2851fecb7a0c565 ]
The ilitek-ili9881c controls the reset GPIO using the non-sleeping
gpiod_set_value() function. This complains loudly when the GPIO
controller needs to sleep. As the caller can sleep, use
gpiod_set_value_cansleep() to fix the issue.

This patch is preliminary work to enable network device
type support to VDUSE.
As VIRTIO_BLK_F_CONFIG_WCE shares the same value as
VIRTIO_NET_F_HOST_TSO4, we need to restrict its check
to Virtio-blk device type.

[ Upstream commit 56e71885b0349241c07631a7b979b61e81afab6a ]
Virtio-net driver control queue implementation is not safe
when used with VDUSE. If the VDUSE application does not
reply to control queue messages, it currently ends up
hanging the kernel thread sending this command.
Some work is on-going to make the control queue
implementation robust with VDUSE. Until it is completed,
let's fail features check if control-queue feature is
requested.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uros Bizjak <ubizjak@gmail.com>
[ Upstream commit 5d31174f3c8c465d9dbe88f6b9d1fe5716f44981 ]
The assembly snippet in restore_fpregs_from_fpstate() that implements
X86_BUG_FXSAVE_LEAK fixup loads the value from a random variable,
preferably the one that is already in the L1 cache.
However, the access to fpinit_state via *fpstate pointer is not
implemented correctly. The "m" asm constraint requires dereferenced
pointer variable, otherwise the compiler just reloads the value
via temporary stack slot. The current asm code reflects this:
mov %rdi,(%rsp)
...
fildl (%rsp)
With dereferenced pointer variable, the code does what the
comment above the asm snippet says:
fildl (%rdi)
Also, remove the pointless %P operand modifier. The modifier is
ineffective on non-symbolic references - it was used to prevent
%rip-relative addresses in .altinstr sections, but FILDL in the
.text section can use %rip-relative addresses without problems.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dawei Li <dawei.li@shingroup.cn>
[ Upstream commit be4e1304419c99a164b4c0e101c7c2a756b635b9 ]
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

From: Joachim Vandersmissen <git@jvdsn.com>
[ Upstream commit 73e5984e540a76a2ee1868b91590c922da8c24c9 ]
private_key is overwritten with the key parameter passed in by the
caller (if present), or alternatively a newly generated private key.
However, it is possible that the caller provides a key (or the newly
generated key) which is shorter than the previous key. In that
scenario, some key material from the previous key would not be
overwritten. The easiest solution is to explicitly zeroize the entire
private_key array first.
Note that this patch slightly changes the behavior of this function:
previously, if the ecc_gen_privkey failed, the old private_key would
remain. Now, the private_key is always zeroized. This behavior is
consistent with the case where params.key is set and ecc_is_key_valid
fails.

From: Ricardo Ribalda <ribalda@chromium.org>
[ Upstream commit 17d1316de0d7dc1bdc5d6e3ad4efd30a9bf1a381 ]
Because the size passed to copy_from_user() cannot be known beforehand,
it needs to be checked during runtime with check_object_size. That makes
gcc believe that the content of sbuf can be used before init.
Fix:

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Erick Archer <erick.archer@outlook.com>
[ Upstream commit ae6a233092747e9652eb793d92f79d0820e01c6a ]
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1] [2].
In this case, the memory allocated to store RADEONFB_CONN_LIMIT pointers
to "drm_connector" structures can be avoided. This is because this
memory area is never accessed.
Also, in the kzalloc function, it is preferred to use sizeof(*pointer)
instead of sizeof(type) due to the type of the variable can change and
one needs not change the former (unlike the latter).
At the same time take advantage to remove the "#if 0" block, the code
where the removed memory area was accessed, and the RADEONFB_CONN_LIMIT
constant due to now is never used.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kent Gibson <warthog618@gmail.com>
[ Upstream commit 9919cce62f68e6ab68dc2a975b5dc670f8ca7d40 ]
linehandle_set_config() behaves badly when direction is not set.
The configuration validation is borrowed from linehandle_create(), where,
to verify the intent of the user, the direction must be set to in order
to effect a change to the electrical configuration of a line. But, when
applied to reconfiguration, that validation does not allow for the unset
direction case, making it possible to clear flags set previously without
specifying the line direction.
Adding to the inconsistency, those changes are not immediately applied by
linehandle_set_config(), but will take effect when the line value is next
get or set.
For example, by requesting a configuration with no flags set, an output
line with GPIOHANDLE_REQUEST_ACTIVE_LOW and GPIOHANDLE_REQUEST_OPEN_DRAIN
requested could have those flags cleared, inverting the sense of the line
and changing the line drive to push-pull on the next line value set.
Ensure the intent of the user by disallowing configurations which do not
have direction set, returning an error to userspace to indicate that the
configuration is invalid.
And, for clarity, use lflags, a local copy of gcnf.flags, throughout when
dealing with the requested flags, rather than a mixture of both.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
[ Upstream commit 093d9603b60093a9aaae942db56107f6432a5dca ]
The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d886 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882dbe ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 403f17a330732a666ae793f3b15bc75bb5540524 ]
The sys_fanotify_mark() syscall on parisc uses the reverse word order
for the two halves of the 64-bit argument compared to all syscalls on
all 32-bit architectures. As far as I can tell, the problem is that
the function arguments on parisc are sorted backwards (26, 25, 24, 23,
...) compared to everyone else, so the calling conventions of using an
even/odd register pair in native word order result in the lower word
coming first in function arguments, matching the expected behavior
on little-endian architectures. The system call conventions however
ended up matching what the other 32-bit architectures do.
A glibc cleanup in 2020 changed the userspace behavior in a way that
handles all architectures consistently, but this inadvertently broke
parisc32 by changing to the same method as everyone else.
The change made it into glibc-2.35 and subsequently into debian 12
(bookworm), which is the latest stable release. This means we
need to choose between reverting the glibc change or changing the
kernel to match it again, but either hange will leave some systems
broken.
Pick the option that is more likely to help current and future
users and change the kernel to match current glibc. This also
means the behavior is now consistent across architectures, but
it breaks running new kernels with old glibc builds before 2.35.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@suse.cz>
commit be346c1a6eeb49d8fda827d2a9522124c2f72f36 upstream.
The code in ocfs2_dio_end_io_write() estimates number of necessary
transaction credits using ocfs2_calc_extend_credits(). This however does
not take into account that the IO could be arbitrarily large and can
contain arbitrary number of extents.
Extent tree manipulations do often extend the current transaction but not
in all of the cases. For example if we have only single block extents in
the tree, ocfs2_mark_extent_written() will end up calling
ocfs2_replace_extent_rec() all the time and we will never extend the
current transaction and eventually exhaust all the transaction credits if
the IO contains many single block extents. Once that happens a
WARN_ON(jbd2_handle_buffer_credits(handle) <= 0) is triggered in
jbd2_journal_dirty_metadata() and subsequently OCFS2 aborts in response to
this error. This was actually triggered by one of our customers on a
heavily fragmented OCFS2 filesystem.
To fix the issue make sure the transaction always has enough credits for
one extent insert before each call of ocfs2_mark_extent_written().

commit ebc4fc34eae8ddfbef49f2bdaced1bf4167ef80d upstream.
jmicron_pmos() and sdhci_pci_probe() use pci_{read,write}_config_byte()
that return PCIBIOS_* codes. The return code is then returned as is by
jmicron_probe() and sdhci_pci_probe(). Similarly, the return code is
also returned as is from jmicron_resume(). Both probe and resume
functions should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning them the fix these issues.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@intel.com>
commit fbd64f902b93fe9658b855b9892ae59ef6ea22b9 upstream.
mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.
sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.
Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".
Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.
Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.
Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

commit ab069ce125965a5e282f7b53b86aee76ab32975c upstream.
sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.
However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().
So remove the locking.

From: Wolfram Sang <wsa+renesas@sang-engineering.com>
[ Upstream commit c422b6a630240f706063e0ecbb894aa8491b1fa1 ]
STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

From: Wolfram Sang <wsa+renesas@sang-engineering.com>
[ Upstream commit c116deafd1a5cc1e9739099eb32114e90623209c ]
When clearing registers on new write requests was added, the protection
for currently running commands was missed leading to concurrent access
to the testunit registers. Check the flag beforehand.

commit ae1f7b93b52095be6776d0f34957b4f35dda44d9 upstream.
The IIO standard units are measured in kPa while the driver
is using hPa.
Apart from checking the userspace value itself, it is mentioned also
in the Bosch API [1] that the pressure value is in Pascal.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vasileios Amoiridis <vassilisamir@gmail.com>
commit 4241665e6ea063a9c1d734de790121a71db763fc upstream.
A read operation is happening as follows:
a) Set sensor to forced mode
b) Sensor measures values and update data registers and sleeps again
c) Read data registers
In the current implementation the read operation happens immediately
after the sensor is set to forced mode so the sensor does not have
the time to update properly the registers. This leads to the following
2 problems:
1) The first ever value which is read by the register is always wrong
2) Every read operation, puts the register into forced mode and reads
the data that were calculated in the previous conversion.
This behaviour was tested in 2 ways:
1) The internal meas_status_0 register was read before and after every
read operation in order to verify that the data were ready even before
the register was set to forced mode and also to check that after the
forced mode was set the new data were not yet ready.
2) Physically changing the temperature and measuring the temperature
This commit adds the waiting time in between the set of the forced mode
and the read of the data. The function is taken from the Bosch BME68x
Sensor API [1].

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jose Ignacio Tornos Martinez <jtornosm@redhat.com>
commit 058722ee350c0bdd664e467156feb2bf5d9cc271 upstream.
Avoid spurious link status logs that may ultimately be wrong; for example,
if the link is set to down with the cable plugged, then the cable is
unplugged and after this the link is set to up, the last new log that is
appearing is incorrectly telling that the link is up.
In order to avoid errors, show link status logs after link_reset
processing, and in order to avoid spurious as much as possible, only show
the link loss when some link status change is detected.

------------------
From: Oliver Neukum <oneukum@suse.com>
commit e587a7633dfee8987a999cf253f7c52a8e09276c upstream.
printer_read() and printer_write() guard against the race
against disable() by checking the dev->interface flag,
which in turn is guarded by a spinlock.
These functions, however, drop the lock on multiple occasions.
This means that the test has to be redone after reacquiring
the lock and before doing IO.
Add the tests.
This also addresses CVE-2024-25741

From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit 2eabb655a968b862bc0c31629a09f0fbf3c80d51 upstream.
Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong
endpoints types may be used at urb sumbitting stage which in turn
triggers a warning in usb_submit_urb().
Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.
Unfortunately, this patch has not been tested on real hardware.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meng Li <Meng.Li@windriver.com>
commit 7838de15bb700c2898a7d741db9b1f3cbc86c136 upstream.
When config CONFIG_USB_DWC3_DUAL_ROLE is selected, and trigger system
to enter suspend status with below command:
echo mem > /sys/power/state
There will be a deadlock issue occurring. Detailed invoking path as
below:
dwc3_suspend_common()
spin_lock_irqsave(&dwc->lock, flags); <-- 1st
dwc3_gadget_suspend(dwc);
dwc3_gadget_soft_disconnect(dwc);
spin_lock_irqsave(&dwc->lock, flags); <-- 2nd
This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix
NULL pointer dereference in dwc3_gadget_suspend") that removes the code
of checking whether dwc->gadget_driver is NULL or not. It causes the
following code is executed and deadlock occurs when trying to get the
spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3:
Remove DWC3 locking during gadget suspend/resume") that forgot to remove
the lock of otg mode. So, remove the redundant lock of otg mode during
gadget suspend/resume.

------------------
From: Udit Kumar <u-kumar1@ti.com>
commit 9d141c1e615795eeb93cd35501ad144ee997a826 upstream.
As per Errata i2310[0], Erroneous timeout can be triggered,
if this Erroneous interrupt is not cleared then it may leads
to storm of interrupts, therefore apply Errata i2310 solution.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Eichenberger <stefan.eichenberger@toradex.com>
commit a81dbd0463eca317eee44985a66aa6cc2ce5c101 upstream.
Set the receiver level to something > 0 before calling imx_uart_start_rx
in rs485_config. This is necessary to avoid an interrupt storm that
might prevent the system from booting. This was seen on an i.MX7 device
when the rs485-rts-active-low property was active in the device tree.

------------------
From: Shigeru Yoshida <syoshida@redhat.com>
commit b7cdf1dd5d2a2d8200efd98d1893684db48fe134 upstream.
syzbot reported kernel-infoleak in raw_recvmsg() [1]. j1939_send_one()
creates full frame including unused data, but it doesn't initialize
it. This causes the kernel-infoleak issue. Fix this by initializing
unused data.

commit 9ad1da14ab3bf23087ae45fe399d84a109ddb81a upstream.
Addresses an issue where a CAN bus error during a BAM transmission
could stall the socket queue, preventing further transmissions even
after the bus error is resolved. The fix activates the next queued
session after the error recovery, allowing communication to continue.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oleksij Rempel <o.rempel@pengutronix.de>
commit d3e2904f71ea0fe7eaff1d68a2b0363c888ea0fb upstream.
This patch enhances error handling in scenarios with RTS (Request to
Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE
backtraces with a new error handling method. This provides clearer error
messages and allows for the early termination of problematic sessions.
Previously, sessions were only released at the end of j1939_xtp_rx_rts().
Potentially this could be reproduced with something like:
testj1939 -r vcan0:0x80 &
while true; do
# send first RTS
cansend vcan0 18EC8090#1014000303002301;
# send second RTS
cansend vcan0 18EC8090#1014000303002301;
# send abort
cansend vcan0 18EC8090#ff00000000002301;
done

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuntao Wang <ytcoode@gmail.com>
commit 932d8476399f622aa0767a4a0a9e78e5341dc0e1 upstream.
Commit 4205e4786d0b ("cpu/hotplug: Provide dynamic range for prepare
stage") added a dynamic range for the prepare states, but did not handle
the assignment of the dynstate variable in __cpuhp_setup_state_cpuslocked().
This causes the corresponding startup callback not to be invoked when
calling __cpuhp_setup_state_cpuslocked() with the CPUHP_BP_PREPARE_DYN
parameter, even though it should be.
Currently, the users of __cpuhp_setup_state_cpuslocked(), for one reason or
another, have not triggered this bug.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dragan Simic <dsimic@manjaro.org>
commit 9cc5f3bf63aa98bd7cc7ce8a8599077fde13283e upstream.
The compiled dtb files aren't executable, so install them with 0644 as their
permission mode, instead of defaulting to 0755 for the permission mode and
installing them with the executable bits set.
Some Linux distributions, including Debian, [1][2][3] already include fixes
in their kernel package build recipes to change the dtb file permissions to
0644 in their kernel packages. These changes, when additionally propagated
into the long-term kernel versions, will allow such distributions to remove
their downstream fixes.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 30766f1105d6d2459c3b9fe34a3e52b637a72950 upstream.
The unusual function calling conventions on SuperH ended up causing
sync_file_range to have the wrong argument order, with the 'flags'
argument getting sorted before 'nbytes' by the compiler.
In userspace, I found that musl, glibc, uclibc and strace all expect the
normal calling conventions with 'nbytes' last, so changing the kernel
to match them should make all of those work.
In order to be able to also fix libc implementations to work with existing
kernels, they need to be able to tell which ABI is used. An easy way
to do this is to add yet another system call using the sync_file_range2
ABI that works the same on all architectures.
Old user binaries can now work on new kernels, and new binaries can
try the new sync_file_range2() to work with new kernels or fall back
to the old sync_file_range() version if that doesn't exist.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 3339b99ef6fe38dac43b534cba3a8a0e29fb2eff upstream.
Both of these architectures require u64 function arguments to be
passed in even/odd pairs of registers or stack slots, which in case of
sync_file_range would result in a seven-argument system call that is
not currently possible. The system call is therefore incompatible with
all existing binaries.
While it would be possible to implement support for seven arguments
like on mips, it seems better to use a six-argument version, either
with the normal argument order but misaligned as on most architectures
or with the reordered sync_file_range2() calling conventions as on
arm and powerpc.

From: Arnd Bergmann <arnd@arndb.de>
commit 896842284c6ccba25ec9d78b7b6e62cdd507c083 upstream.
fadvise64_64() has two 64-bit arguments at the wrong alignment
for hexagon, which turns them into a 7-argument syscall that is
not supported by Linux.
The downstream musl port for hexagon actually asks for a 6-argument
version the same way we do it on arm, csky, powerpc, so make the
kernel do it the same way to avoid having to change both.

In the past, there were similar failures reported by CI from other IGT
tests, observed on other platforms.
Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity
before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for
idleness of vma->active via fence_update(). That commit introduced
vma->fence->active in order for the fence_update() to be able to wait
selectively on that one instead of vma->active since only idleness of
fence registers was needed. But then, another commit 0d86ee35097a
("drm/i915/gt: Make fence revocation unequivocal") replaced the call to
fence_update() in i915_vma_revoke_fence() with only fence_write(), and
also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front.
No justification was provided on why we might then expect idleness of
vma->fence->active without first waiting on it.
The issue can be potentially caused by a race among revocation of fence
registers on one side and sequential execution of signal callbacks invoked
on completion of a request that was using them on the other, still
processed in parallel to revocation of those fence registers. Fix it by
waiting for idleness of vma->fence->active in i915_vma_revoke_fence().

From: Ma Ke <make24@iscas.ac.cn>
commit 6d411c8ccc0137a612e0044489030a194ff5c843 upstream.
In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is
assigned to mode, which will lead to a possible NULL pointer dereference
on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode().
Add a check to avoid null pointer dereference.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sven Eckelmann <sven@narfation.org>
commit 537a350d14321c8cca5efbf0a33a404fec3a9f9e upstream.
The internal handling of VLAN IDs in batman-adv is only specified for
following encodings:
* VLAN is used
- bit 15 is 1
- bit 11 - bit 0 is the VLAN ID (0-4095)
- remaining bits are 0
* No VLAN is used
- bit 15 is 0
- remaining bits are 0
batman-adv was only preparing new translation table entries (based on its
soft interface information) using this encoding format. But the receive
path was never checking if entries in the roam or TT TVLVs were also
following this encoding.
It was therefore possible to create more than the expected maximum of 4096
+ 1 entries in the originator VLAN list. Simply by setting the "remaining
bits" to "random" values in corresponding TVLV.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit eeb25a09c5e0805d92e4ebd12c4b0ad0df1b0295 upstream.
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,
if probe() fails after this call, we currently never call
sysfs_remove_file_from_group().
(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)
Thus, if probe() fails after the sysfs_add_file_to_group() call, the next
time we insmod the module we will get:

From: Niklas Cassel <cassel@kernel.org>
commit ab9e0c529eb7cafebdd31fe1644524e80a48b05d upstream.
If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump
to the err_out label, which will call devres_release_group().
devres_release_group() will trigger a call to ata_host_release().
ata_host_release() calls kfree(host), so executing the kfree(host) in
ata_host_alloc() will lead to a double free:

extension when called in compat mode on 64-bit architectures. As a
result, passing a negative length accidentally succeeds in truncating
to file size between 2GiB and 4GiB.
Changing the type of the compat syscall to the signed compat_off_t
changes the behavior so it instead returns -EINVAL.
The native entry point, the truncate() syscall and the corresponding
loff_t based variants are all correct already and do not suffer
from this mistake.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit d3882564a77c21eb746ba5364f3fa89b88de3d61 upstream.
Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.
This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.
Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 63e2f40c9e3187641afacde4153f54b3ee4dbc8c ]
My earlier fix missed an incorrect function prototype that shows up on
native 32-bit builds:
In file included from fs/notify/fanotify/fanotify_user.c:14:
include/linux/syscalls.h:248:25: error: conflicting types for 'sys_fanotify_mark'; have 'long int(int, unsigned int, u32, u32, int, const char *)' {aka 'long int(int, unsigned int, unsigned int, unsigned int, int, const char *)'}
1924 | SYSCALL32_DEFINE6(fanotify_mark,
| ^~~~~~~~~~~~~~~~~
include/linux/syscalls.h:862:17: note: previous declaration of 'sys_fanotify_mark' with type 'long int(int, unsigned int, u64, int, const char *)' {aka 'long int(int, unsigned int, long long unsigned int, int, const char *)'}
On x86 and powerpc, the prototype is also wrong but hidden in an #ifdef,
so it never caused problems.
Add another alternative declaration that matches the conditional function
definition.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
commit 086d49058cd8471046ae9927524708820f5fd1c7 upstream.
IPv6 has this hack changing sk->sk_prot when an IPv6 socket
is 'converted' to an IPv4 one with IPV6_ADDRFORM option.
This operation is only performed for TCP and UDP, knowing
their 'struct proto' for the two network families are populated
in the same way, and can not disappear while a reader
might use and dereference sk->sk_prot.
If we think about it all reads of sk->sk_prot while
either socket lock or RTNL is not acquired should be using READ_ONCE().
Also note that other layers like MPTCP, XFRM, CHELSIO_TLS also
write over sk->sk_prot.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
commit 364f997b5cfe1db0d63a390fe7c801fa2b3115f6 upstream.
Commit 086d49058cd8 ("ipv6: annotate some data-races around sk->sk_prot")
fixed some data-races around sk->sk_prot but it was not enough.
Some functions in inet6_(stream|dgram)_ops still access sk->sk_prot
without lock_sock() or rtnl_lock(), so they need READ_ONCE() to avoid
load tearing.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuniyuki Iwashima <kuniyu@amazon.com>
commit f49cd2f4d6170d27a2c61f1fecb03d8a70c91f57 upstream.
setsockopt(IPV6_ADDRFORM) and tcp_v6_connect() change icsk->icsk_af_ops
under lock_sock(), but tcp_(get|set)sockopt() read it locklessly. To
avoid load/store tearing, we need to add READ_ONCE() and WRITE_ONCE()
for the reads and writes.
Thanks to Eric Dumazet for providing the syzbot report:

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
[ Commit fdc6d38d64a20c542b1867ebeb8dd03b98829336 upstream ]
The EFI memory map is a description of the memory layout as provided by
the firmware, and only x86 manipulates it in various different ways for
its own memory bookkeeping. So let's move the memmap routines that are
only used by x86 into the x86 arch tree.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
[ Commit d85e3e34940788578eeffd94e8b7e1d28e7278e9 upstream ]
Currently, the EFI_PARAVIRT flag is only used by Xen dom0 boot on x86,
even though other architectures also support pseudo-EFI boot, where the
core kernel is invoked directly and provided with a set of data tables
that resemble the ones constructed by the EFI stub, which never actually
runs in that case.
Let's fix this inconsistency, and always set this flag when booting dom0
via the EFI boot path. Note that Xen on x86 does not provide the EFI
memory map in this case, whereas other architectures do, so move the
associated EFI_PARAVIRT check into the x86 platform code.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
[ Commit 75dde792d6f6c2d0af50278bd374bf0c512fe196 upstream ]
The logic in __efi_memmap_init() is shared between two different
execution flows:
- mapping the EFI memory map early or late into the kernel VA space, so
that its entries can be accessed;
- the x86 specific cloning of the EFI memory map in order to insert new
entries that are created as a result of making a memory reservation
via a call to efi_mem_reserve().
In the former case, the underlying memory containing the kernel's view
of the EFI memory map (which may be heavily modified by the kernel
itself on x86) is not modified at all, and the only thing that changes
is the virtual mapping of this memory, which is different between early
and late boot.
In the latter case, an entirely new allocation is created that carries a
new, updated version of the kernel's view of the EFI memory map. When
installing this new version, the old version will no longer be
referenced, and if the memory was allocated by the kernel, it will leak
unless it gets freed.
The logic that implements this freeing currently lives on the code path
that is shared between these two use cases, but it should only apply to
the latter. So move it to the correct spot.
While at it, drop the dummy definition for non-x86 architectures, as
that is no longer needed.

5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <maz@kernel.org>
commit b321c31c9b7b309dcde5e8854b741c8e6a9a05f0 upstream.
Xiang reports that VMs occasionally fail to boot on GICv4.1 systems when
running a preemptible kernel, as it is possible that a vCPU is blocked
without requesting a doorbell interrupt.
The issue is that any preemption that occurs between vgic_v4_put() and
schedule() on the block path will mark the vPE as nonresident and *not*
request a doorbell irq. This occurs because when the vcpu thread is
resumed on its way to block, vcpu_load() will make the vPE resident
again. Once the vcpu actually blocks, we don't request a doorbell
anymore, and the vcpu won't be woken up on interrupt delivery.
Fix it by tracking that we're entering WFI, and key the doorbell
request on that flag. This allows us not to make the vPE resident
when going through a preempt/schedule cycle, meaning we don't lose
any state.

the flag wranging in the kvm_arch_vcpu_{un}blocking() hooks as the
introduction of kvm_vcpu_wfi has not yet happened. See:
