[ Upstream commit a26cc2934331b57b5a7164bff344f0a2ec245fc0 ]
After commit 3fb16866b51d ("driver core: fw_devlink: Make cycle
detection more robust"), fw_devlink prints an error when consumer
devices don't have their fwnode set. This used to be ignored silently.
Set the fwnode mipi_dsi_device so fw_devlink can find them and properly
track their dependencies.
This fixes errors like this:
[ 0.334054] nwl-dsi 30a00000.mipi-dsi: Failed to create device link with regulator-lcd-1v8
[ 0.346964] nwl-dsi 30a00000.mipi-dsi: Failed to create device link with backlight-dsi

[ Upstream commit f9d36cf445ffff0b913ba187a3eff78028f9b1fb ]
When a tick broadcast clockevent device is initialized for one shot mode
then tick_broadcast_setup_oneshot() OR's the periodic broadcast mode
cpumask into the oneshot broadcast cpumask.
This is required when switching from periodic broadcast mode to oneshot
broadcast mode to ensure that CPUs which are waiting for periodic
broadcast are woken up on the next tick.
But it is subtly broken, when an active broadcast device is replaced and
the system is already in oneshot (NOHZ/HIGHRES) mode. Victor observed
this and debugged the issue.
Then the OR of the periodic broadcast CPU mask is wrong as the periodic
cpumask bits are sticky after tick_broadcast_enable() set it for a CPU
unless explicitly cleared via tick_broadcast_disable().
That means that this sets all other CPUs which have tick broadcasting
enabled at that point unconditionally in the oneshot broadcast mask.
If the affected CPUs were already idle and had their bits set in the
oneshot broadcast mask then this does no harm. But for non idle CPUs
which were not set this corrupts their state.
On their next invocation of tick_broadcast_enable() they observe the bit
set, which indicates that the broadcast for the CPU is already set up.
As a consequence they fail to update the broadcast event even if their
earliest expiring timer is before the actually programmed broadcast
event.
If the programmed broadcast event is far in the future, then this can
cause stalls or trigger the hung task detector.
Avoid this by telling tick_broadcast_setup_oneshot() explicitly whether
this is the initial switch over from periodic to oneshot broadcast which
must take the periodic broadcast mask into account. In the case of
initialization of a replacement device this prevents that the broadcast
oneshot mask is modified.
There is a second problem with broadcast device replacement in this
function. The broadcast device is only armed when the previous state of
the device was periodic.
That is correct for the switch from periodic broadcast mode to oneshot
broadcast mode as the underlying broadcast device could operate in
oneshot state already due to lack of periodic state in hardware. In that
case it is already armed to expire at the next tick.
For the replacement case this is wrong as the device is in shutdown
state. That means that any already pending broadcast event will not be
armed.
This went unnoticed because any CPU which goes idle will observe that
the broadcast device has an expiry time of KTIME_MAX and therefore any
CPUs next timer event will be earlier and cause a reprogramming of the
broadcast device. But that does not guarantee that the events of the
CPUs which were already in idle are delivered on time.
Fix this by arming the newly installed device for an immediate event
which will reevaluate the per CPU expiry times and reprogram the
broadcast device accordingly. This is simpler than caching the last
expiry time in yet another place or saving it before the device exchange
and handing it down to the setup function. Replacement of broadcast
devices is not a frequent operation and usually happens once somewhere
late in the boot process.

[ Upstream commit 162bd18eb55adf464a0fa2b4144b8d61c75ff7c2 ]
Add return value for dim_calc_stats. This is an indication for the
caller if curr_stats was assigned by the function. Avoid using
curr_stats uninitialized over {rdma/net}_dim, when no time delta between
samples. Coverity reported this potential use of an uninitialized
variable.

Using current implementation of polling mode, there is high chances we
will hit into timeout error when running phc2sys. Hence, update the
implementation of hardware crosstimestamping to use the MAC interrupt
service routine instead of polling for TSIS bit in the MAC Timestamp
Interrupt Status register to be set.

[ Upstream commit 8efbdbfa99381a017dd2c0f6375a7d80a8118b74 ]
Initialize MAC_ONEUS_TIC_COUNTER register with correct value derived
from CSR clock, otherwise EEE is unstable on at least NXP i.MX8M Plus
and Micrel KSZ9131RNX PHY, to the point where not even ARP request can
be sent out.
i.MX 8M Plus Applications Processor Reference Manual, Rev. 1, 06/2021
11.7.6.1.34 One-microsecond Reference Timer (MAC_ONEUS_TIC_COUNTER)
defines this register as:
"
This register controls the generation of the Reference time (1 microsecond
tic) for all the LPI timers. This timer has to be programmed by the software
initially.
...
The application must program this counter so that the number of clock cycles
of CSR clock is 1us. (Subtract 1 from the value before programming).
For example if the CSR clock is 100MHz then this field needs to be programmed
to value 100 - 1 = 99 (which is 0x63).
This is required to generate the 1US events that are used to update some of
the EEE related counters.
"
The reset value is 0x63 on i.MX8M Plus, which means expected CSR clock are
100 MHz. However, the i.MX8M Plus "enet_qos_root_clk" are 266 MHz instead,
which means the LPI timers reach their count much sooner on this platform.
This is visible using a scope by monitoring e.g. exit from LPI mode on TX_CTL
line from MAC to PHY. This should take 30us per STMMAC_DEFAULT_TWT_LS setting,
during which the TX_CTL line transitions from tristate to low, and 30 us later
from low to high. On i.MX8M Plus, this transition takes 11 us, which matches
the 30us * 100/266 formula for misconfigured MAC_ONEUS_TIC_COUNTER register.
Configure MAC_ONEUS_TIC_COUNTER based on CSR clock, so that the LPI timers
have correct 1us reference. This then fixes EEE on i.MX8M Plus with Micrel
KSZ9131RNX PHY.

[ Upstream commit dc1c9fd4a8bbe1e06add9053010b652449bfe411 ]
This reverts "netfilter: nf_tables: skip netdev events generated on netns removal".
The problem is that when a veth device is released, the veth release
callback will also queue the peer netns device for removal.
Its possible that the peer netns is also slated for removal. In this
case, the device memory is already released before the pre_exit hook of
the peer netns runs:
BUG: KASAN: slab-use-after-free in nf_hook_entry_head+0x1b8/0x1d0
Read of size 8 at addr ffff88812c0124f0 by task kworker/u8:1/45
Workqueue: netns cleanup_net
Call Trace:
nf_hook_entry_head+0x1b8/0x1d0
__nf_unregister_net_hook+0x76/0x510
nft_netdev_unregister_hooks+0xa0/0x220
__nft_release_hook+0x184/0x490
nf_tables_pre_exit_net+0x12f/0x1b0
..
Order is:
1. First netns is released, veth_dellink() queues peer netns device
for removal
2. peer netns is queued for removal
3. peer netns device is released, unreg event is triggered
4. unreg event is ignored because netns is going down
5. pre_exit hook calls nft_netdev_unregister_hooks but device memory
might be free'd already.

[ Upstream commit e72eeab542dbf4f544e389e64fa13b82a1b6d003 ]
I received a bug report (no reproducer so far) where we trip over
712 rcu_read_lock();
713 ct_hook = rcu_dereference(nf_ct_hook);
714 BUG_ON(ct_hook == NULL); // here
In nf_conntrack_destroy().
First turn this BUG_ON into a WARN. I think it was triggered
via enable_hooks=1 flag.
When this flag is turned on, the conntrack hooks are registered
before nf_ct_hook pointer gets assigned.
This opens a short window where packets enter the conntrack machinery,
can have skb->_nfct set up and a subsequent kfree_skb might occur
before nf_ct_hook is set.
Call nf_conntrack_init_end() to set nf_ct_hook before we register the
pernet ops.

[ Upstream commit 4063384ef762cc5946fc7a3f89879e76c6ec51e2 ]
Before blamed commit, pskb_may_pull() was used instead
of skb_header_pointer() in __vlan_get_protocol() and friends.
Few callers depended on skb->head being populated with MAC header,
syzbot caught one of them (skb_mac_gso_segment())
Add vlan_get_protocol_and_depth() to make the intent clearer
and use it where sensible.
This is a more generic fix than commit e9d3f80935b6
("net/af_packet: make sure to pull mac header") which was
dealing with a similar issue.

[ Upstream commit f4c2e67c1773d2a2632381ee30e9139c1e744c16 ]
Clearing the PBA bit from the driver is race prone and it may lead to
dropped interrupt events. This could potentially lead to the traffic
being completely halted.

[ Upstream commit 90cbed5247439a966b645b34eb0a2e037836ea8e ]
If skb enqueue the qdisc, fq_skb_cb(skb)->time_to_send is changed which
is actually skb->cb, and IPCB(skb_in)->opt will be used in
__ip_options_echo. It is possible that memcpy is out of bounds and lead
to stack overflow.
We should clear skb->cb before ip_local_out or ip6_local_out.
v2:
1. clean the stack info
2. use IPCB/IP6CB instead of skb->cb
crash on stable-5.10(reproduce in kasan kernel).

[ Upstream commit 679ed006d416ea0cecfe24a99d365d1dea69c683 ]
KCSAN found a data race of sk->sk_receive_queue->qlen where recvmsg()
updates qlen under the queue lock and sendmsg() checks qlen under
unix_state_sock(), not the queue lock, so the reader side needs
READ_ONCE().

[ Upstream commit e1d09c2c2f5793474556b60f83900e088d0d366d ]
KCSAN found a data race around sk->sk_shutdown where unix_release_sock()
and unix_shutdown() update it under unix_state_lock(), OTOH unix_poll()
and unix_dgram_poll() read it locklessly.
We need to annotate the writes and reads with WRITE_ONCE() and READ_ONCE().

[ Upstream commit 0ff80028e2702c7c3d78b69705dc47c1ccba8c39 ]
drm_dp_dsc_sink_max_slice_count() may return 0 if something goes
wrong on the part of the DSC sink and its DPCD register. This null
value may be later used as a divisor in intel_dsc_compute_params(),
which will lead to an error.
In the unlikely event that this issue occurs, fix it by testing the
return value of drm_dp_dsc_sink_max_slice_count() against zero.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.

Smatch complains that:
arcfb_probe() warn: 'irq' from request_irq() not released on lines: 587.
Fix error handling in the arcfb_probe() function. If IO addresses are
not provided or framebuffer registration fails, the code will jump to
the err_addr or err_register_fb label to release resources.
If IRQ request fails, previously allocated resources will be freed.

[ Upstream commit 949f95ff39bf188e594e7ecd8e29b82eb108f5bf ]
When we enable MMP in ext4_multi_mount_protect() during mount or
remount, we end up calling sb_start_write() from write_mmp_block(). This
triggers lockdep warning because freeze protection ranks above s_umount
semaphore we are holding during mount / remount. The problem is harmless
because we are guaranteed the filesystem is not frozen during mount /
remount but still let's fix the warning by not grabbing freeze
protection from ext4_multi_mount_protect().

[ Upstream commit 5354b2af34064a4579be8bc0e2f15a7b70f14b5f ]
Previously, ext4_get_group_info() would treat an invalid group number
as BUG(), since in theory it should never happen. However, if a
malicious attaker (or fuzzer) modifies the superblock via the block
device while it is the file system is mounted, it is possible for
s_first_data_block to get set to a very large number. In that case,
when calculating the block group of some block number (such as the
starting block of a preallocation region), could result in an
underflow and very large block group number. Then the BUG_ON check in
ext4_get_group_info() would fire, resutling in a denial of service
attack that can be triggered by root or someone with write access to
the block device.
For a quality of implementation perspective, it's best that even if
the system administrator does something that they shouldn't, that it
will not trigger a BUG. So instead of BUG'ing, ext4_get_group_info()
will call ext4_error and return NULL. We also add fallback code in
all of the callers of ext4_get_group_info() that it might NULL.
Also, since ext4_get_group_info() was already borderline to be an
inline function, un-inline it. The results in a next reduction of the
compiled text size of ext4 by roughly 2k.

[ Upstream commit 6bc6e6b27524304aadb9c04611ddb1c84dd7617a ]
The ref_scale_shutdown() kthread/function uses wait_event() to wait for
the refscale test to complete. However, although the read-side tests
are normally extremely fast, there is no law against specifying a very
large value for the refscale.loops module parameter or against having
a slow read-side primitive. Either way, this might well trigger the
hung-task timeout.
This commit therefore replaces those wait_event() calls with calls to
wait_event_idle(), which do not trigger the hung-task timeout.

[ Upstream commit 3c1566bca3f8349f12b75d0a2d5e4a20ad6262ec ]
For kernels built with CONFIG_PREEMPT_RCU=y, the following scenario can
result in a NULL-pointer dereference:
CPU1 CPU2
rcu_preempt_deferred_qs_irqrestore rcu_print_task_exp_stall
if (special.b.blocked) READ_ONCE(rnp->exp_tasks) != NULL
raw_spin_lock_rcu_node
np = rcu_next_node_entry(t, rnp)
if (&t->rcu_node_entry == rnp->exp_tasks)
WRITE_ONCE(rnp->exp_tasks, np)
....
raw_spin_unlock_irqrestore_rcu_node
raw_spin_lock_irqsave_rcu_node
t = list_entry(rnp->exp_tasks->prev,
struct task_struct, rcu_node_entry)
(if rnp->exp_tasks is NULL, this
will dereference a NULL pointer)
The problem is that CPU2 accesses the rcu_node structure's->exp_tasks
field without holding the rcu_node structure's ->lock and CPU2 did
not observe CPU1's change to rcu_node structure's ->exp_tasks in time.
Therefore, if CPU1 sets rcu_node structure's->exp_tasks pointer to NULL,
then CPU2 might dereference that NULL pointer.
This commit therefore holds the rcu_node structure's ->lock while
accessing that structure's->exp_tasks field.

crafted filesystem image can contain bogus length. There conditions are

Add a helper to get a pointer to struct displayid_header. To be
pedantic, add buffer overflow checks to not touch the base if that
itself would overflow.

[ Upstream commit 7222f5841ff49709ca666b05ff336776e0664a20 ]
[Why & How]
DC now uses a new commit sequence which is more robust since it
addresses cases where we need to reorganize pipes based on planes and
other parameters. As a result, this new commit sequence reset the DC
state by cleaning plane states and re-creating them accordingly with the
need. For this reason, the dce_transform_set_pixel_storage_depth can be
invoked after a plane state is destroyed and before its re-creation. In
this situation and on DCE devices, DC will hit a condition that will
trigger a dmesg log that looks like this:

[ Upstream commit 47e8b73bc35d7c54642f78e498697692f6358996 ]
When the driver calls cx23885_risc_buffer() to prepare the buffer, the
function call dma_alloc_coherent may fail, resulting in a empty buffer
risc->cpu. Later when we free the buffer or access the buffer, null ptr
deref is triggered.
This bug is similar to the following one:
https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae911d71.
We believe the bug can be also dynamically triggered from user side.
Similarly, we fix this by checking the return value of cx23885_risc_buffer()
and the value of risc->cpu before buffer free.

[ Upstream commit 1634b7adcc5bef645b3666fdd564e5952a9e24e0 ]
When the driver calls tw68_risc_buffer() to prepare the buffer, the
function call dma_alloc_coherent may fail, resulting in a empty buffer
buf->cpu. Later when we free the buffer or access the buffer, null ptr
deref is triggered.
This bug is similar to the following one:
https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae911d71.
We believe the bug can be also dynamically triggered from user side.
Similarly, we fix this by checking the return value of tw68_risc_buffer()
and the value of buf->cpu before buffer free.

[ Upstream commit 63264422785021704c39b38f65a78ab9e4a186d7 ]
In r592_probe, dev->detect_timer was bound with r592_detect_timer.
In r592_irq function, the timer function will be invoked by mod_timer.
If we remove the module which will call hantro_release to make cleanup,
there may be a unfinished work. The possible sequence is as follows,
which will cause a typical UAF bug.
Fix it by canceling the work before cleanup in r592_remove.

sdei_cpuhp_up() is called in the STARTING hotplug section,
which runs with interrupts disabled. Use a CPUHP_AP_ONLINE_DYN entry
instead to execute the cpuhp cb later, with preemption enabled.
SDEI originally got its own cpuhp slot to allow interacting
with perf. It got superseded by pNMI and this early slot is not
relevant anymore. [1]
Some SDEI calls (e.g. SDEI_1_0_FN_SDEI_PE_MASK) take actions on the
calling CPU. It is checked that preemption is disabled for them.
_ONLINE cpuhp cb are executed in the 'per CPU hotplug thread'.
Preemption is enabled in those threads, but their cpumask is limited
to 1 CPU.
Move 'WARN_ON_ONCE(preemptible())' statements so that SDEI cpuhp cb
don't trigger them.
Also add a check for the SDEI_1_0_FN_SDEI_PRIVATE_RESET SDEI call
which acts on the calling CPU.

When removing custom query handlers, the handler might still
be used inside the EC query workqueue, causing a kernel oops
if the module holding the callback function was already unloaded.
Fix this by flushing the EC query workqueue when removing
custom query handlers.

In tegra_sor_compute_config(), the 32-bit value mode->clock is
multiplied by 1000, and assigned to the u64 variable pclk. We can avoid
a potential 32-bit integer overflow by casting mode->clock to u64 before
we do the arithmetic and assignment.

From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit b20566cdef05cd40d95f10869d2a7646f48b1bbe ]
The DP AUX interrupt handling was a bit of a mess.
* There were two functions (one for "native" transfers and one for
"i2c" transfers) that were quite similar. It was hard to say how
many of the differences between the two functions were on purpose
and how many of them were just an accident of how they were coded.
* Each function sometimes used "else if" to test for error bits and
sometimes didn't and again it was hard to say if this was on purpose
or just an accident.
* The two functions wouldn't notice whether "unknown" bits were
set. For instance, there seems to be a bit "DP_INTR_PLL_UNLOCKED"
and if it was set there would be no indication.
* The two functions wouldn't notice if more than one error was set.
Let's fix this by being more consistent / explicit about what we're
doing.
By design this could cause different handling for AUX transfers,
though I'm not actually aware of any bug fixed as a result of
this patch (this patch was created because we simply noticed how odd
the old code was by code inspection). Specific notes here:
1. In the old native transfer case if we got "done + wrong address"
we'd ignore the "wrong address" (because of the "else if"). Now we
won't.
2. In the old native transfer case if we got "done + timeout" we'd
ignore the "timeout" (because of the "else if"). Now we won't.
3. In the old native transfer case we'd see "nack_defer" and translate
it to the error number for "nack". This differed from the i2c
transfer case where "nack_defer" was given the error number for
"nack_defer". This 100% can't matter because the only user of this
error number treats "nack defer" the same as "nack", so it's clear
that the difference between the "native" and "i2c" was pointless
here.
4. In the old i2c transfer case if we got "done" plus any error
besides "nack" or "defer" then we'd ignore the error. Now we don't.
5. If there is more than one error signaled by the hardware it's
possible that we'll report a different one than we used to. I don't
know if this matters. If someone is aware of a case this matters we
should document it and change the code to make it explicit.
6. One quirk we keep (I don't know if this is important) is that in
the i2c transfer case if we see "done + defer" we report that as a
"nack". That seemed too intentional in the old code to just drop.
After this change we will add extra logging, including:
* A warning if we see more than one error bit set.
* A warning if we see an unexpected interrupt.
* A warning if we get an AUX transfer interrupt when shouldn't.
It actually turns out that as a result of this change then at boot we
sometimes see an error:
[drm:dp_aux_isr] *ERROR* Unexpected DP AUX IRQ 0x01000000 when not busy
That means that, during init, we are seeing DP_INTR_PLL_UNLOCKED. For
now I'm going to say that leaving this error reported in the logs is
OK-ish and hopefully it will encourage someone to track down what's
going on at init time.
One last note here is that this change renames one of the interrupt
bits. The bit named "i2c done" clearly was used for native transfers
being done too, so I renamed it to indicate this.

Add a simple check that avoids incrementing a pointer by zero, but
otherwise behaves as before. Note that our findings are against ACPICA
20221020, but the same code exists on master.

[ Upstream commit d116db180decec1b21bba31d2ff495ac4d8e1b83 ]
The array is hardcoded to 8 in atomfirmware.h, but firmware provides
a bigger one sometimes. Deferencing the larger array causes an out
of bounds error.
commit 4fc1ba4aa589 ("drm/amd/display: fix array index out of bound error
in bios parser") fixed some of this, but there are two other cases
not covered by it. Fix those as well.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
[ Upstream commit e3a69496a1cde364c74a600d7a370179b58aed29 ]
Structures passed to subdev pad operations are all zero-initialized, but
not always with the same kind of code constructs. While most drivers
used designated initializers, which zero all the fields that are not
specified, when declaring variables, some use memset(). Those two
methods lead to the same end result, and, depending on compiler
optimizations, may even be completely equivalent, but they're not
consistent.
Improve coding style consistency by using designated initializers
instead of calling memset(). Where applicable, also move the variables
to inner scopes of for loops to ensure correct initialization in all
iterations.

[ Upstream commit bfcc8ba45eb87bfaaff900bbad2b87b204899d41 ]
The memcpy() in ath_key_config() was attempting to write across
neighboring struct members in struct ath_keyval. Introduce a wrapping
struct_group, kv_values, to be the addressable target of the memcpy
without overflowing an individual member. Silences the false positive
run-time warning:
memcpy: detected field-spanning write (size 32) of single field "hk.kv_val" at drivers/net/wireless/ath/key.c:506 (size 16)

[ Upstream commit 0a09a2f933c73dc76ab0b72da6855f44342a8903 ]
There are a few cases where hlist_node is checked to be unhashed without
holding the lock protecting its modification. In this case, one must use
hlist_unhashed_lockless to avoid load tearing and KCSAN reports. Fix
this by using lockless variant in places not protected by the lock.
Since this is not prompted by any actual KCSAN reports but only from
code review, I have not included a fixes tag.

[ Upstream commit 89b89e52153fda2733562776c7c9d9d3ebf8dd6d ]
Apparently the hex passphrase mechanism does not work on newer
chips/firmware (e.g. BCM4387). It seems there was a simple way of
passing it in binary all along, so use that and avoid the hexification.
OpenBSD has been doing it like this from the beginning, so this should
work on all chips.
Also clear the structure before setting the PMK. This was leaking
uninitialized stack contents to the device.

[ Upstream commit c6087b82a9146826564a55c5ca0164cac40348f5 ]
A static code analysis tool flagged the possibility of buffer overflow when
using copy_from_user() for a debugfs entry.
Currently, it is possible that copy_from_user() copies more bytes than what
would fit in the mybuf char array. Add a min() restriction check between
sizeof(mybuf) - 1 and nbytes passed from the userspace buffer to protect
against buffer overflow.

warning in clang aims to catch these at compile time, which reveals:
drivers/net/ethernet/pasemi/pasemi_mac.c:1665:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = pasemi_mac_start_tx,
^~~~~~~~~~~~~~~~~~~
1 error generated.
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of
pasemi_mac_start_tx() to match the prototype's to resolve the warning.
While PowerPC does not currently implement support for kCFI, it could in
the future, which means this warning becomes a fatal CFI failure at run
time.

[ Upstream commit 5dd0dfd55baec0742ba8f5625a0dd064aca7db16 ]
When setting the XPS value of a TX queue, warn the user once if the
index of the queue is greater than the number of allocated TX queues.
Previously, this scenario went uncaught. In the best case, it resulted
in unnecessary allocations. In the worst case, it resulted in
out-of-bounds memory references through calls to `netdev_get_tx_queue(
dev, index)`. Therefore, it is important to inform the user but not
worth returning an error and risk downing the netdevice.

[ Upstream commit 4e0473f1060aa49621d40a113afde24818101d37 ]
When calling irq_set_affinity_notifier() with NULL at the notify
argument, it will cause freeing of the glue pointer in the
corresponding array entry but will leave the pointer in the array. A
subsequent call to free_irq_cpu_rmap() will try to free this entry again
leading to possible use after free.
Fix that by setting NULL to the array entry and checking that we have
non-zero at the array entry when iterating over the array in
free_irq_cpu_rmap().
The current code does not suffer from this since there are no cases
where irq_set_affinity_notifier(irq, NULL) (note the NULL passed for the
notify arg) is called, followed by a call to free_irq_cpu_rmap() so we
don't hit and issue. Subsequent patches in this series excersize this
flow, hence the required fix.

[ Upstream commit f486893288f3e9b171b836f43853a6426515d800 ]
mptlan_probe() calls mpt_register_lan_device() which initializes the
&priv->post_buckets_task workqueue. A call to
mpt_lan_wake_post_buckets_task() will subsequently start the work.
During driver unload in mptlan_remove() the following race may occur:
CPU0 CPU1
|mpt_lan_post_receive_buckets_work()
mptlan_remove() |
free_netdev() |
kfree(dev); |
|
| dev->mtu
| //use
Fix this by finishing the work prior to cleaning up in mptlan_remove().
[mkp: we really should remove mptlan instead of attempting to fix it]

The maximum allowed height of an inode's metadata tree depends on the
filesystem block size; it is lower for bigger-block filesystems. When
reading in an inode, make sure that the height doesn't exceed the
maximum allowed height.
Arrays like sd_heightsize are sized to be big enough for any filesystem
block size; they will often be slightly bigger than what's needed for a
specific filesystem.

Besides we should assure goal start is in range [first_data_block,

[ Added a check to make sure size is less than ar->pright; otherwise
we could end up passing an underflowed value of ar->pright - size to

[ Upstream commit 93cdf49f6eca5e23f6546b8f28457b2e6a6961d9 ]
When the length of best extent found is less than the length of goal extent
we need to make sure that the best extent atleast covers the start of the
original request. This is done by adjusting the ac_b_ex.fe_logical (logical
start) of the extent.
While doing so, the current logic sometimes results in the best extent's
logical range overflowing the goal extent. Since this best extent is later
added to the inode preallocation list, we have a possibility of introducing
overlapping preallocations. This is discussed in detail here [1].
As per Jan's suggestion, to fix this, replace the existing logic with the
below logic for adjusting best extent as it keeps fragmentation in check
while ensuring logical range of best extent doesn't overflow out of goal
extent:
1. Check if best extent can be kept at end of goal range and still cover
original start.
2. Else, check if best extent can be kept at start of goal range and still
cover original start.
3. Else, keep the best extent at start of original request.
Also, add a few extra BUG_ONs that might help catch errors faster.

During umount(), if cp_error is set, f2fs_wait_on_all_pages() should
not stop waiting all F2FS_WB_CP_DATA pages to be writebacked, otherwise,
fsync_node_num can be non-zero after f2fs_wait_on_all_pages() causing
this bug.
In this case, to avoid deadloop in f2fs_wait_on_all_pages(), it needs
to drop all dirty pages rather than redirtying them.

one of secondary device is set as ro, later update will cause panic, so
let's introduce f2fs_dev_is_readonly(), and check multi-devices rw status

That is because in __bpf_prog_exit_recur, the preempt_count_{sub,add} are
called after prog->active is decreased.
Fixing this by adding these two functions into btf ids deny list.

It is possible that iwl_pci_probe() will fail and free the trans,
then afterwards iwl_pci_remove() will be called and crash by trying
to access trans which is already freed, fix it.

[ Upstream commit 58d1b717879bfeabe09b35e41ad667c79933eb2e ]
An integer overflow occurs in the iwl_write_to_user_buf() function,
which is called by the iwl_dbgfs_monitor_data_read() function.
static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,
void *buf, ssize_t *size,
ssize_t *bytes_copied)
{
int buf_size_left = count - *bytes_copied;
buf_size_left = buf_size_left - (buf_size_left % sizeof(u32));
if (*size > buf_size_left)
*size = buf_size_left;
If the user passes a SIZE_MAX value to the "ssize_t count" parameter,
the ssize_t count parameter is assigned to "int buf_size_left".
Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a
negative number, so "*size" is assigned "buf_size_left" and goes into
the third argument of the copy_to_user function, causing a heap overflow.
This is not a security vulnerability because iwl_dbgfs_monitor_data_read()
is a debugfs operation with 0400 privileges.

[ Upstream commit ef16799640865f937719f0771c93be5dca18adc6 ]
A received TKIP key may be up to 32 bytes because it may contain
MIC rx/tx keys too. These are not used by iwl and copying these
over overflows the iwl_keyinfo.key field.
Add a check to not copy more data to iwl_keyinfo.key then will fit.
This fixes backtraces like this one:

[ Upstream commit f9fff67d2d7ca6fa8066132003a3deef654c55b1 ]
While running traffics for a long time, randomly an RX descriptor
filled with value "0" from REO destination ring is received.
This descriptor which is invalid causes the wrong SKB (SKB stored in
the IDR lookup with buffer id "0") to be fetched which in turn
causes SKB memory corruption issue and the same leads to crash
after some time.
Changed the start id for idr allocation to "1" and the buffer id "0"
is reserved for error validation. Introduced Sanity check to validate
the descriptor, before processing the SKB.
Crash Signature :
Unable to handle kernel paging request at virtual address 3f004900
PC points to "b15_dma_inv_range+0x30/0x50"
LR points to "dma_cache_maint_page+0x8c/0x128".
The Backtrace obtained is as follows:

[ Upstream commit 55793ea54d77719a071b1ccc05a05056e3b5e009 ]
We tested and found an alarm caused by nbd_ioctl arg without verification.
The UBSAN warning calltrace like below:
UBSAN: Undefined behaviour in fs/buffer.c:1709:35
signed integer overflow:
-9223372036854775808 - 1 cannot be represented in type 'long long int'
CPU: 3 PID: 2523 Comm: syz-executor.0 Not tainted 4.19.90 #1

The reason for triggering this warning is __block_write_full_page()
-> i_size_read(inode) - 1 overflow.
inode->i_size is assigned in __nbd_ioctl() -> nbd_set_size() -> bytesize.
We think it is necessary to limit the size of arg to prevent errors.
Moreover, __nbd_ioctl() -> nbd_add_socket(), arg will be cast to int.
Assuming the value of arg is 0x80000000000000001) (on a 64-bit machine),
it will become 1 after the coercion, which will return unexpected results.
Fix it by adding checks to prevent passing in too large numbers.

[ Upstream commit e3478c68f6704638d08f437cbc552ca5970c151a ]
In ip_vs_sync_conn_v0() copy is made to struct ip_vs_sync_conn_options.
That structure looks like this:
struct ip_vs_sync_conn_options {
struct ip_vs_seq in_seq;
struct ip_vs_seq out_seq;
};
The source of the copy is the in_seq field of struct ip_vs_conn. Whose
type is struct ip_vs_seq. Thus we can see that the source - is not as
wide as the amount of data copied, which is the width of struct
ip_vs_sync_conn_option.
The copy is safe because the next field in is another struct ip_vs_seq.
Make use of struct_group() to annotate this.

From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 0d218c3642b9ccf71f44987cd03c19320f3bd918 ]
On some devices the BCM Bluetooth adapter does not have a valid bdaddr set.
btbcm.c currently sets HCI_QUIRK_INVALID_BDADDR to indicate when this is
the case. But this requires users to manual setup a btaddr, by doing e.g.:
btmgmt -i hci0 public-addr 'B0:F1:EC:82:1D:B3'
Which means that Bluetooth will not work out of the box on such devices.
To avoid this (where possible) hci_bcm sets: HCI_QUIRK_USE_BDADDR_PROPERTY
which tries to get the bdaddr from devicetree.
But this only works on devicetree platforms. On UEFI based platforms
there is a special Broadcom UEFI variable which when present contains
the devices bdaddr, just like how there is another UEFI variable which
contains wifi nvram contents including the wifi MAC address.
Add support for getting the bdaddr from this Broadcom UEFI variable,
so that Bluetooth will work OOTB for users on devices where this
UEFI variable is present.
This fixes Bluetooth not working on for example Asus T100HA 2-in-1s.

[ Upstream commit 7ad1fe0da0fa91bf920b79ab05ae97bfabecc4f4 ]
For devices that support the 0x0003 feature (Device Information) version 4,
set the serial based on the output of that feature, rather than relying
on the usbhid code setting the USB serial.
This should allow the serial when connected through USB to (nearly)
match the one when connected through a unifying receiver.
For example, on the serials on a G903 wired/wireless mouse:
- Unifying: 4067-e8-ce-cd-45
- USB before patch: 017C385C3837
- USB after patch: c086-e8-ce-cd-45

Now that USB HID++ devices can gather a serial number that matches the
one that would be gathered when connected through a Unifying receiver,
remove the last difference by dropping the product ID as devices
usually have different product IDs when connected through USB or
Unifying.
For example, on the serials on a G903 wired/wireless mouse:
- Unifying before patch: 4067-e8-ce-cd-45
- USB before patch: c086-e8-ce-cd-45
- Unifying and USB after patch: e8-ce-cd-45

[ Upstream commit 87c614175bbf28d3fd076dc2d166bac759e41427 ]
When using gpio based chip select the cs value can go outside the range
0 – 3. The various MX51_ECSPI_* macros did not take this into consideration
resulting in possible corruption of the configuration.
For example for any cs value over 3 the SCLKPHA bits would not be set and
other values in the register possibly corrupted.
One way to fix this is to just mask the cs bits to 2 bits. This still
allows all 4 native chip selects to work as well as gpio chip selects
(which can use any of the 4 chip select configurations).

Some devices will include battery status usages in the HID descriptor
but we won't see that battery data for one reason or another. For example,
AES sensors won't send battery data unless an AES pen is in proximity.
If a user does not have an AES pen but instead only interacts with the
AES touchscreen with their fingers then there is no need for us to create
a battery object. Similarly, if a family of peripherals shares the same
HID descriptor between wired-only and wireless-capable SKUs, users of the
former may never see a battery event and will not want a power_supply
object created.

PD3.0 Spec 6.4.4.3.2 say that only Responder supports 12 or more SVIDs,
the Discover SVIDs Command Shall be executed multiple times until a
Discover SVIDs VDO is returned ending either with a SVID value of
0x0000 in the last part of the last VDO or with a VDO containing two
SVIDs with values of 0x0000.
In the current implementation, if the last VDO does not find that the
Discover SVIDs Command would be executed multiple times even if the
Responder SVIDs are less than 12, and we found some odd dockers just
meet this case. So fix it.

[ Upstream commit 04e82793f068d2f0ffe62fcea03d007a8cdc16a7 ]
When we unbind a serial port hardware specific 8250 driver, the generic
serial8250 driver takes over the port. After that we see an oops about 10
seconds later. This can produce the following at least on some TI SoCs:
Unhandled fault: imprecise external abort (0x1406)
Internal error: : 1406 [#1] SMP ARM
Turns out that we may still have the serial port hardware specific driver
port->pm in use, and serial8250_pm() tries to call it after the port
specific driver is gone:
serial8250_pm [8250_base] from uart_change_pm+0x54/0x8c [serial_base]
uart_change_pm [serial_base] from uart_hangup+0x154/0x198 [serial_base]
uart_hangup [serial_base] from __tty_hangup.part.0+0x328/0x37c
__tty_hangup.part.0 from disassociate_ctty+0x154/0x20c
disassociate_ctty from do_exit+0x744/0xaac
do_exit from do_group_exit+0x40/0x8c
do_group_exit from __wake_up_parent+0x0/0x1c
Let's fix the issue by calling serial8250_set_defaults() in
serial8250_unregister_port(). This will set the port back to using
the serial8250 default functions, and sets the port->pm to point to
serial8250_pm.

mcb-pci requests a fixed-size memory region to parse the chameleon
table, however, if the chameleon table is smaller that the allocated
region, it could overlap with the IP Cores' memory regions.
After parsing the chameleon table, drop/reallocate the memory region
with the actual chameleon table size.

[ Upstream commit aa4d540b4150052ae3b36d286b9c833a961ce291 ]
GCC-13 (and Clang)[1] does not like to access a partially allocated
object, since it cannot reason about it for bounds checking.
In this case 140 bytes are allocated for an object of type struct
ib_umad_packet:
packet = kzalloc(sizeof(*packet) + IB_MGMT_RMPP_HDR, GFP_KERNEL);
However, notice that sizeof(*packet) is only 104 bytes:
struct ib_umad_packet {
struct ib_mad_send_buf * msg; /* 0 8 */
struct ib_mad_recv_wc * recv_wc; /* 8 8 */
struct list_head list; /* 16 16 */
int length; /* 32 4 */
/* XXX 4 bytes hole, try to pack */
struct ib_user_mad mad __attribute__((__aligned__(8))); /* 40 64 */
/* size: 104, cachelines: 2, members: 5 */
/* sum members: 100, holes: 1, sum holes: 4 */
/* forced alignments: 1, forced holes: 1, sum forced holes: 4 */
/* last cacheline: 40 bytes */
} __attribute__((__aligned__(8)));
and 36 bytes extra bytes are allocated for a flexible-array member in
struct ib_user_mad:
include/rdma/ib_mad.h:
120 enum {
...
123 IB_MGMT_RMPP_HDR = 36,
... }
struct ib_user_mad {
struct ib_user_mad_hdr hdr; /* 0 64 */
/* --- cacheline 1 boundary (64 bytes) --- */
__u64 data[] __attribute__((__aligned__(8))); /* 64 0 */
/* size: 64, cachelines: 1, members: 2 */
/* forced alignments: 1 */
} __attribute__((__aligned__(8)));
So we have sizeof(*packet) + IB_MGMT_RMPP_HDR == 140 bytes
Then the address of the flex-array member (for which only 36 bytes were
allocated) is casted and copied into a pointer to struct ib_rmpp_mad,
which, in turn, is of size 256 bytes:
rmpp_mad = (struct ib_rmpp_mad *) packet->mad.data;
struct ib_rmpp_mad {
struct ib_mad_hdr mad_hdr; /* 0 24 */
struct ib_rmpp_hdr rmpp_hdr; /* 24 12 */
u8 data[220]; /* 36 220 */
/* size: 256, cachelines: 4, members: 3 */
};
The thing is that those 36 bytes allocated for flex-array member data
in struct ib_user_mad onlly account for the size of both struct ib_mad_hdr
and struct ib_rmpp_hdr, but nothing is left for array u8 data[220].
So, the compiler is legitimately complaining about accessing an object
for which not enough memory was allocated.
Apparently, the only members of struct ib_rmpp_mad that are relevant
(that are actually being used) in function ib_umad_write() are mad_hdr
and rmpp_hdr. So, instead of casting packet->mad.data to
(struct ib_rmpp_mad *) create a new structure
struct ib_rmpp_mad_hdr {
struct ib_mad_hdr mad_hdr;
struct ib_rmpp_hdr rmpp_hdr;
} __packed;
and cast packet->mad.data to (struct ib_rmpp_mad_hdr *).
Notice that
IB_MGMT_RMPP_HDR == sizeof(struct ib_rmpp_mad_hdr) == 36 bytes
Refactor the rest of the code, accordingly.
Fix the following warnings seen under GCC-13 and -Warray-bounds:

[ Upstream commit 12261134732689b7e30c59db9978f81230965181 ]
Some platforms support more than 128 stream matching groups than what is
defined by the ARM SMMU architecture specification. But due to some unknown
reasons, those additional groups don't exhibit the same behavior as the
architecture supported ones.
For instance, the additional groups will not detect the quirky behavior of
some firmware versions intercepting writes to S2CR register, thus skipping
the quirk implemented in the driver and causing boot crash.
So let's limit the groups to 128 for now until the issue with those groups
are fixed and issue a notice to users in that case.

Above issue may happens as follows:
ntfs_new_inode
mi_init
mi->mrec = kmalloc(sbi->record_size, GFP_NOFS); -->failed to allocate memory
if (!mi->mrec)
return -ENOMEM;
iput
iput_final
evict
ntfs_evict_inode
ni_write_inode
is_rec_inuse(ni->mi.mrec)-> As 'ni->mi.mrec' is NULL trigger NULL-ptr-deref
To solve above issue if new inode failed make inode bad before call 'iput()' in
'ntfs_new_inode()'.

[ Upstream commit 8dae4f6341e335a09575be60b4fdf697c732a470 ]
Syzbot reports a NULL dereference in ni_write_inode.
When creating a new inode, if allocation fails in mi_init function
(called in mi_format_new function), mi->mrec is set to NULL.
In the error path of this inode creation, mi->mrec is later
dereferenced in ni_write_inode.
Add a NULL check to prevent NULL dereference.

[ Upstream commit 98bea253aa28ad8be2ce565a9ca21beb4a9419e5 ]
Log load and replay is part of the metadata handle flow during mount
operation. The $MFT record will be loaded and used while replaying logs.
However, a malformed $MFT record, say, has RECORD_FLAG_DIR flag set and
contains an ATTR_ROOT attribute will misguide kernel to treat it as a
directory, and try to free the allocated resources when the
corresponding inode is freed, which will cause an invalid kfree because
the memory hasn't actually been allocated.

[ Upstream commit ec275bf9693d19cc0fdce8436f4c425ced86f6e7 ]
In a previous commit c1006bd13146, ni->mi.mrec in ni_write_inode()
could be NULL, and thus a NULL check is added for this variable.
However, in the same call stack, ni->mi.mrec can be also dereferenced
in ni_clear():
ntfs_evict_inode(inode)
ni_write_inode(inode, ...)
ni = ntfs_i(inode);
is_rec_inuse(ni->mi.mrec) -> Add a NULL check by previous commit
ni_clear(ntfs_i(inode))
is_rec_inuse(ni->mi.mrec) -> No check
Thus, a possible null-pointer dereference may exist in ni_clear().
To fix it, a NULL check is added in this function.

From: Tomas Krcka <krckatom@amazon.de>
[ Upstream commit 67ea0b7ce41844eae7c10bb04dfe66a23318c224 ]
When an overflow occurs in the PRI queue, the SMMU toggles the overflow
flag in the PROD register. To exit the overflow condition, the PRI thread
is supposed to acknowledge it by toggling this flag in the CONS register.
Unacknowledged overflow causes the queue to stop adding anything new.
Currently, the priq thread always writes the CONS register back to the
SMMU after clearing the queue.
The writeback is not necessary if the OVFLG in the PROD register has not
been changed, no overflow has occured.
This commit checks the difference of the overflow flag between CONS and
PROD register. If it's different, toggles the OVACKFLG flag in the CONS
register and write it to the SMMU.
The situation is similar for the event queue.
The acknowledge register is also toggled after clearing the event
queue but never propagated to the hardware. This would only be done the
next time when executing evtq thread.
Unacknowledged event queue overflow doesn't affect the event
queue, because the SMMU still adds elements to that queue when the
overflow condition is active.
But it feel nicer to keep SMMU in sync when possible, so use the same
way here as well.

[ Upstream commit 2367e0ecb498764e95cfda691ff0828f7d25f9a4 ]
There are two issues related to the number of ports coming from
Devicetree when exceeding in total QCOM_SDW_MAX_PORTS. Both lead to
incorrect memory accesses:
1. With DTS having too big value of input or output ports, the driver,
when copying port parameters from local/stack arrays into 'pconfig'
array in 'struct qcom_swrm_ctrl', will iterate over their sizes.
2. If DTS also has too many parameters for these ports (e.g.
qcom,ports-sinterval-low), the driver will overflow buffers on the
stack when reading these properties from DTS.
Add a sanity check so incorrect DTS will not cause kernel memory
corruption.

[ Upstream commit 829632dae8321787525ee37dc4828bbe6edafdae ]
The panic notifiers' callbacks execute in an atomic context, with
interrupts/preemption disabled, and all CPUs not running the panic
function are off, so it's very dangerous to wait on a regular
spinlock, there's a risk of deadlock.
Refactor the panic notifier of parisc/power driver to make use
of spin_trylock - for that, we've added a second version of the
soft-power function. Also, some comments were reorganized and
trailing white spaces, useless header inclusion and blank lines
were removed.

[ Upstream commit 430cac487400494c19a8b85299e979bb07b4671f ]
The current code doesn't let a simple "allow" policy counteract a
default policy blocking all incoming packets:
ip x p setdefault in block
ip x p a src 192.168.2.1/32 dst 192.168.2.2/32 dir in action allow
At this stage, we have an allow policy (with or without transforms)
for this packet. It doesn't matter what the default policy says, since
the policy we looked up lets the packet through. The case of a
blocking policy is already handled separately, so we can remove this
check.
Fixes: 2d151d39073a ("xfrm: Add possibility to set the default to block if we have no policy")

[ Upstream commit 5fc46f94219d1d103ffb5f0832be9da674d85a73 ]
This reverts commit b0355dbbf13c0052931dd14c38c789efed64d3de.
The reverted commit clears the secpath on packets received via xfrm interfaces
to support nested IPsec tunnels. This breaks Netfilter policy matching using
xt_policy in the FORWARD chain, as the secpath is missing during forwarding.
Additionally, Benedict Wong reports that it breaks Transport-in-Tunnel mode.
Fix this regression by reverting the commit until we have a better approach
for nested IPsec tunnels.

[ Upstream commit 85c636284cb63b7740b4ae98881ace92158068d3 ]
while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.
Fix this by unregistering codecs on unbind.

[ Upstream commit c2adb1877b76fc81ae041e1db1a6ed2078c6746b ]
System-wide TSC read could cause a drift in C0 percentage calculation.
Because if first TSC is read and then one by one mperf is read for all
cpus, this introduces drift between mperf reading of later CPUs and TSC
reading. To lower this drift read TSC per CPU and also just after mperf
read. This technique improves C0 percentage calculation in Mperf monitor.

[ Upstream commit cf3128a7aca55b2eefb68281d44749c683bdc96f ]
xfrm_state_find() uses `encap_family` of the current template with
the passed local and remote addresses to find a matching state.
If an optional tunnel or BEET mode template is skipped in a mixed-family
scenario, there could be a mismatch causing an out-of-bounds read as
the addresses were not replaced to match the family of the next template.
While there are theoretical use cases for optional templates in outbound
policies, the only practical one is to skip IPComp states in inbound
policies if uncompressed packets are received that are handled by an
implicitly created IPIP state instead.

[ Upstream commit 21a933c79a33add3612808f3be4ad65dd4dc026b ]
The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of
several routers (rt-1, rt-2) and hosts.
When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate
Address Detection (DAD) kicks in when enabled in the Linux distros running
the selftests. DAD is used to check whether an IPv6 address is already
assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo
Request and waiting for a reply.
As the DAD process could take too long to complete, it may cause the
failing of some tests carried out by the srv6_end_dt4_l3vpn_test script.
To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers
since we configure the virtual network manually and do not need any address
deduplication mechanism at all.

[ Upstream commit f97b8401e0deb46ad1e4245c21f651f64f55aaa6 ]
On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT4 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

[ Upstream commit f816b9829b19394d318e01953aa3b2721bca040d ]
In the (unlikely) event that pm_runtime_get() (disguised as
pm_runtime_resume_and_get()) fails, the remove callback returned an
error early. The problem with this is that the driver core ignores the
error value and continues removing the device. This results in a
resource leak. Worse the devm allocated resources are freed and so if a
callback of the driver is called later the register mapping is already
gone which probably results in a crash.

This potentially leads to a use after free.

[ Upstream commit 6d4486efe9c69626cab423456169e250a5cd3af5 ]
When client and server establish a connection through vsock,
the client send a request to the server to initiate the connection,
then start a timer to wait for the server's response. When the server's
RESPONSE message arrives, the timer also times out and exits. The
server's RESPONSE message is processed first, and the connection is
established. However, the client's timer also times out, the original
processing logic of the client is to directly set the state of this vsock
to CLOSE and return ETIMEDOUT. It will not notify the server when the port
is released, causing the server port remain.
when client's vsock_connect timeout，it should check sk state is
ESTABLISHED or not. if sk state is ESTABLISHED, it means the connection
is established, the client should not set the sk state to CLOSE
Note: I encountered this issue on kernel-4.18, which can be fixed by
this patch. Then I checked the latest code in the community
and found similar issue.

[ Upstream commit 1e306ec49a1f206fd2cc89a42fac6e6f592a8cc1 ]
When tcp_v4_send_reset() is called with @sk == NULL,
we do not change ctl_sk->sk_priority, which could have been
set from a prior invocation.
Change tcp_v4_send_reset() to set sk_priority and sk_mark
fields before calling ip_send_unicast_reply().
This means tcp_v4_send_reset() and tcp_v4_send_ack()
no longer have to clear ctl_sk->sk_mark after
their call to ip_send_unicast_reply().

[ Upstream commit d80fc101d2eb9b3188c228d61223890aeea480a4 ]
In commit 20704bd1633d ("erspan: build the header with the right proto
according to erspan_ver"), it gets the proto with t->parms.erspan_ver,
but t->parms.erspan_ver is not used by collect_md branch, and instead
it should get the proto with md->version for collect_md.
Thanks to Kevin for pointing this out.

[ Upstream commit 814d0c786068e858d889ada3153bff82f64223ad ]
Currently the hns3 vf function reset delays 5000ms before vf rebuild
process. In product applications, this delay is too long for application
configurations and causes configuration timeout.
According to the tests, 500ms delay is enough for reset process except PF
FLR. So this patch modifies delay to 500ms in these scenarios.

[ Upstream commit 0f5bb36bf9b39a2a96e730bf4455095b50713f63 ]
When Universal DVB card is detaching, netup_unidvb_dma_fini()
uses del_timer() to stop dma->timeout timer. But when timer
handler netup_unidvb_dma_timeout() is running, del_timer()
could not stop it. As a result, the use-after-free bug could
happen. The process is shown below:
(cleanup routine) | (timer routine)
| mod_timer(&dev->tx_sim_timer, ..)
netup_unidvb_finidev() | (wait a time)
netup_unidvb_dma_fini() | netup_unidvb_dma_timeout()
del_timer(&dma->timeout); |
| ndev->pci_dev->dev //USE
Fix by changing del_timer() to del_timer_sync().

[ Upstream commit eb8d3a2c809abd73ab0a060fe971d6b9019aa3c1 ]
When an RPC request is deferred, the rq_xprt_ctxt pointer is moved out
of the svc_rqst into the svc_deferred_req.
When the deferred request is revisited, the pointer is copied into
the new svc_rqst - and also remains in the svc_deferred_req.
In the (rare?) case that the request is deferred a second time, the old
svc_deferred_req is reused - it still has all the correct content.
However in that case the rq_xprt_ctxt pointer is NOT cleared so that
when xpo_release_xprt is called, the ctxt is freed (UDP) or possible
added to a free list (RDMA).
When the deferred request is revisited for a second time, it will
reference this ctxt which may be invalid, and the free the object a
second time which is likely to oops.
So change svc_defer() to *always* clear rq_xprt_ctxt, and assert that
the value is now stored in the svc_deferred_req.

[ Upstream commit d07c9ad622474616e94572e59e725c2c4a494fb4 ]
Enable a struct sockaddr to be stored in a trace record as a
dynamically-sized field. The common cases are AF_INET and AF_INET6
which are different sizes, and are vastly smaller than a struct
sockaddr_storage.
These are safer because, when used properly, the size of the
sockaddr destination field in each trace record is now guaranteed
to be the same as the source address that is being copied into it.

Replace the temporary fix from commit 4d5004451ab2 ("SUNRPC: Fix the
svc_deferred_event trace class") with the use of __sockaddr and
friends, which is the preferred solution (but only available in 5.18
and newer).

[ Upstream commit 948f072ada23e0a504c5e4d7d71d4c83bd0785ec ]
Since the ->xprt_ctxt pointer was added to svc_deferred_req, it has not
been sufficient to use kfree() to free a deferred request. We may need
to free the ctxt as well.
As freeing the ctxt is all that ->xpo_release_rqst() does, we repurpose
it to explicit do that even when the ctxt is not stored in an rqst.
So we now have ->xpo_release_ctxt() which is given an xprt and a ctxt,
which may have been taken either from an rqst or from a dreq. The
caller is now responsible for clearing that pointer after the call to
->xpo_release_ctxt.
We also clear dr->xprt_ctxt when the ctxt is moved into a new rqst when
revisiting a deferred request. This ensures there is only one pointer
to the ctxt, so the risk of double freeing in future is reduced. The
new code in svc_xprt_release which releases both the ctxt and any
rq_deferred depends on this.

The root cause is:
nsh_gso_segment() use skb->network_header - nhoff to reset mac_header
in skb_gso_error_unwind() if inner-layer protocol gso fails.
However, skb->network_header may be reset by inner-layer protocol
gso function e.g. mpls_gso_segment. skb->mac_header reset by the
inaccurate network_header will be larger than skb headroom.
nsh_gso_segment
nhoff = skb->network_header - skb->mac_header;
__skb_pull(skb,nsh_len)
skb_mac_gso_segment
mpls_gso_segment
skb_reset_network_header(skb);//skb->network_header+=nsh_len
return -EINVAL;
skb_gso_error_unwind
skb_push(skb, nsh_len);
skb->mac_header = skb->network_header - nhoff;
// skb->mac_header > skb->headroom, cause skb_push panic
Use correct mac_offset to restore mac_header and get rid of nhoff.

[ Upstream commit 5306623a9826aa7d63b32c6a3803c798a765474d ]
When initializing XDP in virtnet_open(), some rq xdp initialization
may hit an error causing net device open failed. However, previous
rqs have already initialized XDP and enabled NAPI, which is not the
expected behavior. Need to roll back the previous rq initialization
to avoid leaks in error unwinding of init code.
Also extract helper functions of disable and enable queue pairs.
Use newly introduced disable helper function in error unwinding and
virtnet_close. Use enable helper function in virtnet_open.

As different media may requires different min mtu, and even the
same media with different net family requires different min mtu,
add tipc_bearer_min_mtu() to calculate min mtu accordingly.
This API will be used to check the new mtu when doing the link

[ Upstream commit 56077b56cd3fb78e1c8619e29581ba25a5c55e86 ]
When doing link mtu negotiation, a malicious peer may send Activate msg
with a very small mtu, e.g. 4 in Shuang's testing, without checking for
the minimum mtu, l->mtu will be set to 4 in tipc_link_proto_rcv(), then
n->links[bearer_id].mtu is set to 4294967228, which is a overflow of
'4 - INT_H_SIZE - EMSG_OVERHEAD' in tipc_link_mss().
With tipc_link.mtu = 4, tipc_link_xmit() kept printing the warning:
tipc: Too large msg, purging xmit list 1 5 0 40 4!
tipc: Too large msg, purging xmit list 1 15 0 60 4!
And with tipc_link_entry.mtu 4294967228, a huge skb was allocated in
named_distribute(), and when purging it in tipc_link_xmit(), a crash
was even caused:

[ Upstream commit 35a089b5d793d2bfd2cc7cfa6104545184de2ce7 ]
Checking the bearer min mtu with tipc_udp_mtu_bad() only works for
IPv4 UDP bearer, and IPv6 UDP bearer has a different value for the
min mtu. This patch checks with encap_hlen + TIPC_MIN_BEARER_MTU
for min mtu, which works for both IPv4 and IPv6 UDP bearer.
Note that tipc_udp_mtu_bad() is still used to check media min mtu
in __tipc_nl_media_set(), as m->mtu currently is only used by the
IPv4 UDP bearer as its default mtu value.

[ Upstream commit b1b0d5aec1cf9f9a900a14964f869c68688d923e ]
Currently when the new channel-path is enabled, we do evaluation only
on the subchannels with a device connected on it. This is because,
in the past, if the device in the subchannel is not working or not
available, we used to unregister the subchannels. But, from the 'commit
2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")'
we allow subchannels with or without an active device connected
on it. So, when we do the io_subchannel_verify, make sure that,
we are evaluating the subchannels without any device too.

[ Upstream commit 93e0401e0fc0c54b0ac05b687cd135c2ac38187c ]
The call to phy_stop() races with the later call to phy_disconnect(),
resulting in concurrent phy_suspend() calls being run from different
CPUs. The final call to phy_disconnect() ensures that the PHY is
stopped and suspended, too.

[ Upstream commit 225c657945c4a6307741cb3cc89467eadcc26e9b ]
Removing the phy_stop() from bcmgenet_netif_stop() ended up causing
warnings from the PHY library that phy_start() is called from the
RUNNING state since we are no longer stopping the PHY state machine
during bcmgenet_suspend().
Restore the call to phy_stop() but make it conditional on being called
from the close or suspend path.

[ Upstream commit c2d8b7f257b2398f2d866205365895e038beca12 ]
Lockdep points out that we can deadlock here by calling
cancel_delayed_work_sync() because that might be already
running and gotten interrupted by the NAPI soft-IRQ.
Even just calling something that can sleep is wrong in
this context though.
Luckily, it doesn't even really matter since the things
we need to do are idempotent, so just drop the _sync().

[ Upstream commit 682b6dc29d98e857e6ca4bbc077c7dc2899b7473 ]
If the firmware sends us a corrupted MCC response with
n_channels much larger than the command response can be,
we might copy far too much (uninitialized) memory and
even crash if the n_channels is large enough to make it
run out of the one page allocated for the FW response.
Fix that by checking the lengths. Doing a < comparison
would be sufficient, but the firmware should be doing
it correctly, so check more strictly.

[ Upstream commit 4e81a6cba517cb33584308a331f14f5e3fec369b ]
In a SCSI request, storvsc pre-allocates space for up to
MAX_PAGE_BUFFER_COUNT physical frame numbers to be passed to Hyper-V. If
the size of the I/O request requires more PFNs, a separate memory area of
exactly the correct size is dynamically allocated.
But when the pre-allocated area is used, current code always passes
MAX_PAGE_BUFFER_COUNT PFNs to Hyper-V, even if fewer are needed. While
this doesn't break anything because the additional PFNs are always zero,
more bytes than necessary are copied into the VMBus channel ring buffer.
This takes CPU cycles and wastes space in the ring buffer. For a typical 4
Kbyte I/O that requires only a single PFN, 248 unnecessary bytes are
copied.
Fix this by setting the payload_sz based on the actual number of PFNs
required, not the size of the pre-allocated space.

[ Upstream commit 60d758659f1fb49e0d5b6ac2691ede8c0958795b ]
In igb_hash_mc_addr() the expression:
"mc_addr[4] >> 8 - bit_shift", right shifting "mc_addr[4]"
shift by more than 7 bits always yields zero, so hash becomes not so different.
Add initialization with bit_shift = 1 and add a loop condition to ensure
bit_shift will be always in [1..8] range.

[ Upstream commit dacab578c7c6cd06c50c89dfa36b0e0f10decd4e ]
syzbot triggered the following splat [1], sending an empty message
through pppoe_sendmsg().
When VLAN_FLAG_REORDER_HDR flag is set, vlan_dev_hard_header()
does not push extra bytes for the VLAN header, because vlan is offloaded.
Unfortunately vlan_dev_hard_start_xmit() first reads veth->h_vlan_proto
before testing (vlan->flags & VLAN_FLAG_REORDER_HDR).
We need to swap the two conditions.

[ Upstream commit 89dcd87ce534a3a7f267cfd58505803006f51301 ]
When CONFIG_BRIDGE_VLAN_FILTERING is disabled, two functions are still
defined but have no prototype or caller. This causes a W=1 warning for
the missing prototypes:
net/bridge/br_netlink_tunnel.c:29:6: error: no previous prototype for 'vlan_tunid_inrange' [-Werror=missing-prototypes]
net/bridge/br_netlink_tunnel.c:199:5: error: no previous prototype for 'br_vlan_tunnel_info' [-Werror=missing-prototypes]
The functions are already contitional on CONFIG_BRIDGE_VLAN_FILTERING,
and I coulnd't easily figure out the right set of #ifdefs, so just
move the declarations out of the #ifdef to avoid the warning,
at a small cost in code size over a more elaborate fix.

commit 359b4315471181f108723c61612d96e383e56179 upstream.
Line6 Pod Go (0e41:424b) requires the similar workaround for the fixed
48k sample rate like other Line6 models. This patch adds the
corresponding entry to line6_parse_audio_format_rate_quirk().

commit 94d25e9128988c6a1fc9070f6e98215a95795bd8 upstream.
The syzbot fuzzer found a problem in the usbtmc driver: When a user
submits an ioctl for a 0-length control transfer, the driver does not
check that the direction is set to OUT:

commit a398d5eac6984316e71474e25b975688f282379b upstream.
With faulty usb-storage devices, read/write can timeout, in that case
the SCSI layer will abort and re-issue the command. USB storage has no
internal timeout, it relies on SCSI layer aborting commands via
.eh_abort_handler() for non those responsive devices.
After two consecutive timeouts of the same command, SCSI layer calls
.eh_device_reset_handler(), without calling .eh_abort_handler() first.
With usb-storage, this causes a deadlock:
-> .eh_device_reset_handler
-> device_reset
-> mutex_lock(&(us->dev_mutex));
mutex already by usb_stor_control_thread(), which is waiting for
command completion:
-> usb_stor_control_thread (mutex taken here)
-> usb_stor_invoke_transport
-> usb_stor_Bulk_transport
-> usb_stor_bulk_srb
-> usb_stor_bulk_transfer_sglist
-> usb_sg_wait
Make sure we cancel any pending command in .eh_device_reset_handler()
to avoid this.

commit dddb342b5b9e482bb213aecc08cbdb201ea4f8da upstream.
OverCurrent condition is not standardized in the UHCI spec.
Zhaoxin UHCI controllers report OverCurrent bit active off.
In order to handle OverCurrent condition correctly, the uhci-hcd
driver needs to be told to expect the active-off behavior.

commit 614ce6a2ea50068b45339257891e51e639ac9001 upstream.
When the dwc3 device is runtime suspended, various required clocks are in
disabled state and it is not guaranteed that access to any registers would
work. Depending on the SoC glue, a register read could be as benign as
returning 0 or be fatal enough to hang the system.
In order to prevent such scenarios of fatal errors, make sure to resume
dwc3 then allow the function to proceed.

commit 3c0f4f09c063e143822393d99cb2b19a85451c07 upstream.
The CDC-ECM specification [1] requires to send the host MAC address as
an uppercase hexadecimal string in chapter "5.4 Ethernet Networking
Functional Descriptor":
The Unicode character is chosen from the set of values 30h through
39h and 41h through 46h (0-9 and A-F).
However, snprintf(.., "%pm", ..) generates a lowercase MAC address
string. While most host drivers are tolerant to this, UsbNcm.sys on
Windows 10 is not. Instead it uses a different MAC address with all
bytes set to zero including and after the first byte containing a
lowercase letter. On Windows 11 Microsoft fixed it, but apparently they
did not backport the fix.
This change fixes the issue by upper-casing the MAC to comply with the
specification.

commit 2a821fc3136d5d99dcb9de152be8a052ca27d870 upstream.
Donghun reports that a notebook that has an AMD Ryzen 5700U but supports
S3 has problems with USB after resuming from suspend. The issue was
bisected down to commit d1658268e439 ("usb: pci-quirks: disable D3cold on
xhci suspend for s2idle on AMD Renoir").
As this issue only happens on S3, narrow the broken D3cold quirk to only
run in s2idle.

commit fe82f16aafdaf8002281d3b9524291d4a4a28460 upstream.
This incorrect tracking caused unnecessary ring expansion in some
usecases which over days of use consume a lot of memory.
xhci driver tries to keep track of free transfer blocks (TRBs) on the
ring buffer, but failed to add back some cancelled transfers that were
turned into no-op operations instead of just moving past them.
This can happen if there are several queued pending transfers which
then are cancelled in reverse order.
Solve this by counting the numer of steps we move the dequeue pointer
once we complete a transfer, and add it to the number of free trbs
instead of just adding the trb number of the current transfer.
This way we ensure we count the no-op trbs on the way as well.

commit 3b44ec8c5c44790a82f07e90db45643c762878c6 upstream.
get_line_out_pfx() may trigger an Oops by overflowing the static array
with more than 8 channels. This was reported for MacBookPro 12,1 with
Cirrus codec.
As a workaround, extend for the 9.1 channels and also fix the
potential Oops by unifying the code paths accessing the same array
with the proper size check.

commit bf7ac55e991ca177f1ac16be51152f1ef291a4df upstream.
The listen-only bit was never cleared, causing the controller to
always use listen-only mode, if previously set.

commit 262d7a52ba27525e3c1203230c9f0524e48bbb34 upstream.
Under certain circumstances we send two EFLUSH commands, resulting in two
EFLUSH ack packets, while only expecting a single EFLUSH ack.
This can cause the driver Tx flush completion to get out of sync.
To avoid this problem, don't enable the "Transmit buffer flush done" (TFD)
interrupt and remove the code handling it.
Now we only send EFLUSH command after receiving status packet with
"Init detected" (IDET) bit set.

From: Bharath SM <bharathsm@microsoft.com>
commit 47592fa8eb03742048b096b4696ec133384c45eb upstream.
Oplock break may occur for different file handle than the deferred
handle. Check for inode deferred closes list, if it's not empty then
close all the deferred handles of inode because we should not cache
handles if we dont have handle lease.
Eg: If openfilelist has one deferred file handle and another open file
handle from app for a same file, then on a lease break we choose the
first handle in openfile list. The first handle in list can be deferred
handle or actual open file handle from app. In case if it is actual open
handle then today, we don't close deferred handles if we lose handle lease
on a file. Problem with this is, later if app decides to close the existing
open handle then we still be caching deferred handles until deferred close
timeout. Leaving open handle may result in sharing violation when windows
client tries to open a file with limited file share access.
So we should check for deferred list of inode and walk through the list of
deferred files in inode and close all deferred files.

commit 59a556aebc43dded08535fe97d94ca3f657915e4 upstream.
In cifs_oplock_break function we drop reference to a cfile at
the end of function, due to which close command goes on wire
after lease break acknowledgment even if file is already closed
by application but we had deferred the handle close.
If other client with limited file shareaccess waiting on lease
break ack proceeds operation on that file as soon as first client
sends ack, then we may encounter status sharing violation error
because of open handle.
Solution is to put reference to cfile(send close on wire if last ref)
and then send oplock acknowledgment to server.

commit e7b8b8ed9960bf699bf4029f482d9e869c094ed6 upstream.
clc length is now accepted to <= 8 less than length,
rather than < 8.
Solve issues on some of Axis's smb clients which send
messages where clc length is 8 bytes less than length.
The specific client was running kernel 4.19.217 with
smb dialect 3.0.2 on armv7l.

commit 443d61d1fa9faa60ef925513d83742902390100f upstream.
ksmbd_smb2_check_message allows client to return one byte more, so we
need to allocate additional memory in ksmbd_conn_handler_loop to avoid
out-of-bound access.

commit f0a96d1aafd8964e1f9955c830a3e5cb3c60a90f upstream.
The offset of UserName is related to the address of security
buffer. To ensure the validaty of UserName, we need to compare name_off
+ name_len with secbuf_len instead of auth_msg_len.

commit ed40866ec7d328b3dfb70db7e2011640a16202c3 upstream.
s390's struct statfs and struct statfs64 contain padding, which
field-by-field copying does not set. Initialize the respective structs
with zeros before filling them and copying them to userspace, like it's
already done for the compat versions of these structs.
Found by KMSAN.

commit d2b00516de0e1d696724247098f6733a6ea53908 upstream.
Add support for Advantech PCI-1611U card
Advantech provides opensource drivers for this and many others card
based on legacy copy of 8250_pci driver called adv950
https://www.advantech.com/emt/support/details/driver?id=1-TDOIMJ
It is hard to maintain to run as out of tree module on newer kernels.
Just adding PCI ID to kernel 8250_pci works perfect.

commit 95d698869b404772cc8b72560df71548491c10bc upstream.
Possibly the last PCI controller-based (i.e. not a soft/winmodem)
dial-up modem one can still buy.
Looks to have a stock XR17C154 PCI UART chip for communication, but for
some reason when provisioning the PCI IDs they swapped the vendor and
subvendor IDs. Otherwise this card would have worked out of the box.
Searching online, some folks seem to not have this issue and others do,
so it is possible only some batches of cards have this error.
Create a new macro to handle the switched IDs and add support here.

Adding UART port triggers probe of child serial devices - serdev and
eventually Qualcomm Bluetooth hci_qca driver. This opens UART port
which enables the interrupt before it got activated in
request_threaded_irq(). The issue originates in commit f3974413cf02
("tty: serial: qcom_geni_serial: Wakeup IRQ cleanup") and discussion on
mailing list [1]. However the above commit does not explain why the
uart_add_one_port() is moved above requesting interrupt.

commit c4af8e3fecd03b0aedcd38145955605cfebe7e3a upstream.
When `QUIRK_AUTO_CLEAR_INT` isn't set, interrupt masking should be
cleared by writing to Interrupt Mask Clear (IMR) and interrupt
status should be cleared properly at shutdown/init.
This fixes an error where interrupts are left enabled during resume
from hibernation with `CONFIG_USB4=y`.

commit 8fb9ea65c9d1338b0d2bb0a9122dc942cdd32357 upstream.
After a call to console_unlock() in vcs_write() the vc_data struct can be
freed by vc_port_destruct(). Because of that, the struct vc_data pointer
must be reloaded in the while loop in vcs_write() after console_lock() to
avoid a UAF when vcs_size() is called.
Syzkaller reported a UAF in vcs_size().

commit e7d3e5c4b1dd50a70b31524c3228c62bb41bbab2 upstream.
The P360 Tiny suffers from an irq storm issue like the T490s, so add
an entry for it to tpm_tis_dmi_table, and force polling. There also
previously was a report from the previous attempt to enable interrupts
that involved a ThinkPad L490. So an entry is added for it as well.

commit 66b2ca086210732954a7790d63d35542936fc664 upstream.
It was reported that soft dirty tracking doesn't work when using the
Radix MMU.
The tracking is supposed to work by clearing the soft dirty bit for a
mapping and then write protecting the PTE. If/when the page is written
to, a page fault occurs and the soft dirty bit is added back via
pte_mkdirty(). For example in wp_page_reuse():
entry = maybe_mkwrite(pte_mkdirty(entry), vma);
if (ptep_set_access_flags(vma, vmf->address, vmf->pte, entry, 1))
update_mmu_cache(vma, vmf->address, vmf->pte);
Unfortunately on radix _PAGE_SOFTDIRTY is being dropped by
radix__ptep_set_access_flags(), called from ptep_set_access_flags(),
meaning the soft dirty bit is not set even though the page has been
written to.
Fix it by adding _PAGE_SOFTDIRTY to the set of bits that are able to be
changed in radix__ptep_set_access_flags().

commit 9b5a04ac3ad9898c4745cba46ea26de74ba56a8e upstream.
During unmount process of nilfs2, nothing holds nilfs_root structure after
nilfs2 detaches its writer in nilfs_detach_log_writer(). However, since
nilfs_evict_inode() uses nilfs_root for some cleanup operations, it may
cause use-after-free read if inodes are left in "garbage_list" and
released by nilfs_dispose_list() at the end of nilfs_detach_log_writer().
Fix this issue by modifying nilfs_evict_inode() to only clear inode
without additional metadata changes that use nilfs_root if the file system
is degraded to read-only or the writer is detached.

commit 2862a2fdfae875888e3c1c3634e3422e01d98147 upstream.
Use "a" constraint instead of "d" constraint to pass the state parameter to
the do_sqbs() inline assembly. This prevents that general purpose register
zero is used for the state parameter.
If the compiler would select general purpose register zero this would be
problematic for the used instruction in rsy format: the register used for
the state parameter is a base register. If the base register is general
purpose register zero the contents of the register are unexpectedly ignored
when the instruction is executed.
This only applies to z/VM guests using QIOASSIST with dedicated (pass through)
QDIO-based devices such as FCP [zfcp driver] as well as real OSA or
HiperSockets [qeth driver].
A possible symptom for this case using zfcp is the following repeating kernel
message pattern:
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: qdio: ZFCP on SC <sc> using AI:1 QEBSM:1 PRI:1 TDD:1 SIGA: W
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
Each of the qdio problem message can be accompanied by the following entries
for the affected subchannel <sc> in
/sys/kernel/debug/s390dbf/qdio_error/hex_ascii for zfcp or qeth:
<sc> ccq: 69....
<sc> SQBS ERROR.

commit 94b179052f95c294d83e9c9c34f7833cf3cd4305 upstream.
Prox-out events may not be reliably sent by some AES firmware. This can
cause problems for users, particularly due to arbitration logic disabling
touch input while the pen is in prox.
This commit adds a timer which is reset every time a new prox event is
received. When the timer expires we check to see if the pen is still in
prox and force it out if necessary. This is patterend off of the same
solution used by 'hid-letsketch' driver which has a similar problem.

I can't found a call for reviewing 5.10.181-rc1, either in my inbox or
on lore.kernel.org.
There does to be a 5.10.181-rc1 in stable-rc/linux-5.10.y, so did it
not get e-mailed out somehow? Or did I somehow miss it?
Anyway, I tested this commit using gce-xfstests, and I didn't detect
any ext4 test regressions.

I did not release it, sorry, only 5.15.y and newer for this round.
5.10.181-rc will probably happen later this week or next.

Ah, no worries. I had a bit of extra time and had set up a pull of
the stable-rc git tree, and was looking at trying to automate some
ext4 testing, and I ended up testing the -rc1 of 6.1, 5.15, 5.10, 5.4,
and 4.19. (At least as was found in the git tree; I assume they
haven't been finalized yet?)
