[ Upstream commit c8687694bb1f5c48134f152f8c5c2e53483eb99d ]
The fbdev test of IGT may write after EOF, which lead to out-of-bound
access for drm drivers with fbdev-generic. For example, run fbdev test
on a x86+ast2400 platform, with 1680x1050 resolution, will cause the
linux kernel hang with the following call trace:

The is because damage rectangles computed by
drm_fb_helper_memory_range_to_clip() function is not guaranteed to be
bound in the screen's active display area. Possible reasons are:
1) Buffers are allocated in the granularity of page size, for mmap system
call support. The shadow screen buffer consumed by fbdev emulation may
also choosed be page size aligned.
2) The DIV_ROUND_UP() used in drm_fb_helper_memory_range_to_clip()
will introduce off-by-one error.
For example, on a 16KB page size system, in order to store a 1920x1080
XRGB framebuffer, we need allocate 507 pages. Unfortunately, the size
1920*1080*4 can not be divided exactly by 16KB.
1920 * 1080 * 4 = 8294400 bytes
506 * 16 * 1024 = 8290304 bytes
507 * 16 * 1024 = 8306688 bytes
line_length = 1920*4 = 7680 bytes
507 * 16 * 1024 / 7680 = 1081.6
off / line_length = 507 * 16 * 1024 / 7680 = 1081
DIV_ROUND_UP(507 * 16 * 1024, 7680) will yeild 1082
memcpy_toio() typically issue the copy line by line, when copy the last
line, out-of-bound access will be happen. Because:
1082 * line_length = 1082 * 7680 = 8309760, and 8309760 > 8306688
Note that userspace may still write to the invisiable area if a larger
buffer than width x stride is exposed. But it is not a big issue as
long as there still have memory resolve the access if not drafting so
far.
- Also limit the y1 (Daniel)
- keep fix patch it to minimal (Daniel)
- screen_size is page size aligned because of it need mmap (Thomas)
- Adding fixes tag (Thomas)

[ Upstream commit 1b617bc93178912fa36f87a957c15d1f1708c299 ]
Some legacy BIOSes report no reserved bits in their 32-bit rgb mode,
breaking the calculation of bits_per_pixel in commit f35cd3fa7729
("firmware/sysfb: Fix EFI/VESA format selection"). However they report
lfb_depth correctly for those modes. Keep the computation but
set bits_per_pixel to lfb_depth if the latter is larger.
v2 fixes the warnings from a max3() macro with arguments of different
types; split the bits_per_pixel assignment to avoid uglyfing the code
with too many typecasts.
v3 fixes space and formatting blips pointed out by Javier, and change
the bit_per_pixel assignment back to a single statement using two casts.
v4 go back to v2 and use max_t()

[ 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:

[ Upstream commit 424f8416bb39936df6365442d651ee729b283460 ]
skb->transport_header uses the special 0xFFFF value
to mark if the transport header was set or not.
We must prevent callers to accidentaly set skb->transport_header
to 0xFFFF. Note that only fuzzers can possibly do this today.

[ Upstream commit 1d1bfe30dad50d4bea83cd38d73c441972ea0173 ]
data->sample_flags may be modified in perf_prepare_sample(),
in perf_tp_event(), different swevents use the same on-stack
perf_sample_data, the previous swevent may change sample_flags in
perf_prepare_sample(), as a result, some members of perf_sample_data are
not correctly initialized when next swevent_event preparing sample
(for example data->id, the value varies according to swevent).
A simple scenario triggers this problem is as follows:
# perf record -e sched:sched_switch --switch-output-event sched:sched_switch -a sleep 1
[ perf record: dump data: Woken up 0 times ]
[ perf record: Dump perf.data.2023041209014396 ]

# perf script -i perf.data.2023041209014396
0x11d58 [0x80]: failed to process type: 9 [Bad address]
Solution: Re-initialize perf_sample_data after each event is processed.
Note that data->raw->frag.data may be accessed in perf_tp_event_match().
Therefore, need to init sample_data and then go through swevent hlist to prevent
reference of NULL pointer, reported by [1].
After fix:

[ 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.

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

[ 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 582dbb2cc1a0a7427840f5b1e3c65608e511b061 ]
Since the driver works in the "legacy" addressing mode, we need to write
to the expansion register (0x17) with bits 11:8 set to 0xf to properly
select the expansion register passed as argument.

[ 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

__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 9949e2efb54eb3001cb2f6512ff3166dddbfb75d ]
Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3ce9
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.
ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000
To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.

[ Upstream commit e05a5f510f26607616fecdd4ac136310c8bea56b ]
do_recvmmsg() can write to sk->sk_err from multiple threads.
As said before, many other points reading or writing sk_err
need annotations.

[ Upstream commit d0ac89f6f9879fae316c155de77b5173b3e2c9c9 ]
__condition is evaluated twice in sk_wait_event() macro.
First invocation is lockless, and reads can race with writes,
as spotted by syzbot.

[ 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 e14cadfd80d76f01bfaa1a8d745b1db19b57d6be ]
Now sk->sk_shutdown is no longer a bitfield, we can add
standard READ_ONCE()/WRITE_ONCE() annotations to silence
KCSAN reports like the following:

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).

Commit d4c367650704 ("net: mscc: ocelot: keep ocelot_stat_layout by reg
address, not offset") organized the stats counters for Ocelot chips, namely
the VSC7512 and VSC7514. A few of the counter offsets were incorrect, and
were caught by this warning:
WARNING: CPU: 0 PID: 24 at drivers/net/ethernet/mscc/ocelot_stats.c:909

reg 0x5000078 had address 0x220 but reg 0x5000079 has address 0x214,
bulking broken!
Fix these register offsets.

[ Upstream commit 2da5bffe9eaa5819a868e8eaaa11b3fd0f16a691 ]
During an IGT GPU reset test we see again oops despite of
commit 0c8c901aaaebc9 (drm/sched: Check scheduler ready before calling
timeout handling).
It uses ready condition whether to call drm_sched_fault which unwind
the TDR leads to GPU reset.
However it looks the ready condition is overloaded with other meanings,
for example, for the following stack is related GPU reset :
0 gfx_v9_0_cp_gfx_start
1 gfx_v9_0_cp_gfx_resume
2 gfx_v9_0_cp_resume
3 gfx_v9_0_hw_init
4 gfx_v9_0_resume
5 amdgpu_device_ip_resume_phase2
does the following:
/* start the ring */
gfx_v9_0_cp_gfx_start(adev);
ring->sched.ready = true;
The same approach is for other ASICs as well :
gfx_v8_0_cp_gfx_resume
gfx_v10_0_kiq_resume, etc...
As a result, our GPU reset test causes GPU fault which calls unconditionally gfx_v9_0_fault
and then drm_sched_fault. However now it depends on whether the interrupt service routine
drm_sched_fault is executed after gfx_v9_0_cp_gfx_start is completed which sets the ready
field of the scheduler to true even for uninitialized schedulers and causes oops vs
no fault or when ISR drm_sched_fault is completed prior gfx_v9_0_cp_gfx_start and
NULL pointer dereference does not occur.
Use the field timeout_wq to prevent oops for uninitialized schedulers.
The field could be initialized by the work queue of resetting the domain.

KCSAN found a data race of sk->sk_receive_queue->qlen where recvmsg()
updates qlen under the queue lock and sendmsg() checks qlen under

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().

A pair of pre-Xe registers were being included in the Xe capture list.
GuC was rejecting those as being invalid and logging errors about
them. So, stop doing it.

[ Upstream commit a41d985902c153c31c616fe183cf2ee331e95ecb ]
intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't
obtained previously with intel_atomic_get_crtc_state, so we must check it
for NULLness here, just as in many other places, where we can't guarantee
that intel_atomic_get_crtc_state was called.
We are currently getting NULL ptr deref because of that, so this fix was
confirmed to help.

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.

[ Upstream commit 79c901c93562bdf1c84ce6c1b744fbbe4389a6eb ]
For development and testing purposes, the i915.force_probe module
parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of
devices that aren't supported by the driver.
The i915.force_probe module parameter is "unsafe" and setting it taints
the kernel. However, using the kconfig option does not.
Always taint the kernel when force probing a device that is not
supported.

[ Upstream commit 5a6bef734247c7a8c19511664ff77634ab86f45b ]
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.
Fixes: 1154ea7dcd8e ("[PATCH] Framebuffer driver for Arc LCD board")

If EXT4_MB_HINT_GOAL_ONLY is set, ext4_mb_regular_allocator will only
allocate blocks from ext4_mb_find_by_goal. Allow to find by goal in
ext4_mb_find_by_goal if EXT4_MB_HINT_GOAL_ONLY is set or allocation
with EXT4_MB_HINT_GOAL_ONLY set will always fail.
EXT4_MB_HINT_GOAL_ONLY is not used at all, so the problem is not

[ 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.

There are several 'malloc' calls in test_memcontrol, which can be
unsuccessful. This patch will add 'malloc' failures checking to
give more details about test's fail reasons and avoid possible
undefined behavior during the future null dereference (like the
one in alloc_anon_50M_check_swap function).

[ 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.

[ Upstream commit 43b450632676fb60e9faeddff285d9fac94a4f58 ]
After a couple of years and multiple LTS releases we received a report
that the behavior of O_DIRECTORY | O_CREAT changed starting with v5.7.
On kernels prior to v5.7 combinations of O_DIRECTORY, O_CREAT, O_EXCL
had the following semantics:
(1) open("/tmp/d", O_DIRECTORY | O_CREAT)
* d doesn't exist: create regular file
* d exists and is a regular file: ENOTDIR
* d exists and is a directory: EISDIR
(2) open("/tmp/d", O_DIRECTORY | O_CREAT | O_EXCL)
* d doesn't exist: create regular file
* d exists and is a regular file: EEXIST
* d exists and is a directory: EEXIST
(3) open("/tmp/d", O_DIRECTORY | O_EXCL)
* d doesn't exist: ENOENT
* d exists and is a regular file: ENOTDIR
* d exists and is a directory: open directory
On kernels since to v5.7 combinations of O_DIRECTORY, O_CREAT, O_EXCL
have the following semantics:
(1) open("/tmp/d", O_DIRECTORY | O_CREAT)
* d doesn't exist: ENOTDIR (create regular file)
* d exists and is a regular file: ENOTDIR
* d exists and is a directory: EISDIR
(2) open("/tmp/d", O_DIRECTORY | O_CREAT | O_EXCL)
* d doesn't exist: ENOTDIR (create regular file)
* d exists and is a regular file: EEXIST
* d exists and is a directory: EEXIST
(3) open("/tmp/d", O_DIRECTORY | O_EXCL)
* d doesn't exist: ENOENT
* d exists and is a regular file: ENOTDIR
* d exists and is a directory: open directory
This is a fairly substantial semantic change that userspace didn't
notice until Pedro took the time to deliberately figure out corner
cases. Since no one noticed this breakage we can somewhat safely assume
that O_DIRECTORY | O_CREAT combinations are likely unused.
The v5.7 breakage is especially weird because while ENOTDIR is returned
indicating failure a regular file is actually created. This doesn't make
a lot of sense.
Time was spent finding potential users of this combination. Searching on
codesearch.debian.net showed that codebases often express semantical
expectations about O_DIRECTORY | O_CREAT which are completely contrary
to what our code has done and currently does.
The expectation often is that this particular combination would create
and open a directory. This suggests users who tried to use that
combination would stumble upon the counterintuitive behavior no matter
if pre-v5.7 or post v5.7 and quickly realize neither semantics give them
what they want. For some examples see the code examples in [1] to [3]
and the discussion in [4].
There are various ways to address this issue. The lazy/simple option
would be to restore the pre-v5.7 behavior and to just live with that bug
forever. But since there's a real chance that the O_DIRECTORY | O_CREAT
quirk isn't relied upon we should try to get away with murder(ing bad
semantics) first. If we need to Frankenstein pre-v5.7 behavior later so
be it.
So let's simply return EINVAL categorically for O_DIRECTORY | O_CREAT
combinations. In addition to cleaning up the old bug this also opens up
the possiblity to make that flag combination do something more intuitive
in the future.
Starting with this commit the following semantics apply:
(1) open("/tmp/d", O_DIRECTORY | O_CREAT)
* d doesn't exist: EINVAL
* d exists and is a regular file: EINVAL
* d exists and is a directory: EINVAL
(2) open("/tmp/d", O_DIRECTORY | O_CREAT | O_EXCL)
* d doesn't exist: EINVAL
* d exists and is a regular file: EINVAL
* d exists and is a directory: EINVAL
(3) open("/tmp/d", O_DIRECTORY | O_EXCL)
* d doesn't exist: ENOENT
* d exists and is a regular file: ENOTDIR
* d exists and is a directory: open directory
One additional note, O_TMPFILE is implemented as:
#define __O_TMPFILE 020000000
#define O_TMPFILE (__O_TMPFILE | O_DIRECTORY)
#define O_TMPFILE_MASK (__O_TMPFILE | O_DIRECTORY | O_CREAT)
For older kernels it was important to return an explicit error when
O_TMPFILE wasn't supported. So O_TMPFILE requires that O_DIRECTORY is
raised alongside __O_TMPFILE. It also enforced that O_CREAT wasn't
specified. Since O_DIRECTORY | O_CREAT could be used to create a regular
allowing that combination together with __O_TMPFILE would've meant that
false positives were possible, i.e., that a regular file was created
instead of a O_TMPFILE. This could've been used to trick userspace into
thinking it operated on a O_TMPFILE when it wasn't.
Now that we block O_DIRECTORY | O_CREAT completely the check for O_CREAT
in the __O_TMPFILE branch via if ((flags & O_TMPFILE_MASK) != O_TMPFILE)
can be dropped. Instead we can simply check verify that O_DIRECTORY is
raised via if (!(flags & O_DIRECTORY)) and explain this in two comments.
As Aleksa pointed out O_PATH is unaffected by this change since it
always returned EINVAL if O_CREAT was specified - with or without
O_DIRECTORY.

[Why]
System restart observed while changing the display resolution
to 8k with extended mode. Sytem restart was caused by a page fault.
[How]
When the driver populates subvp info it did it for both the pipes using
vblank which caused an outof bounds array access causing the page fault.
added checks to allow the top pipe only to fix this issue.

[ Upstream commit f3f8f16b10f8258f1836e1110099097490a1d6c1 ]
[Why]
In disable_dangling_plane, for phantom pipes, we enable OTG so
disable programming gets the double buffer update. But this
causes an underflow to occur.
[How]
Enable DPG prior to enabling OTG.

[ Upstream commit 2f0cf1e85ddb5ae17284050dc1adafb89e4f1d8f ]
The Acer Iconia One 7 B1-750 is a x86 ACPI tablet which ships with Android
x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the I2C + other devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.

[Why]
There is underflow and flickering occuring. The
underflow stops when hostvm is forced to active.
According to policy, hostvm should be enabled if riommu
is active, but this is not taken into account when
deciding whether to enable hostvm.
[What]
For DCN314, set hostvm to true if riommu is active.

[ 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:

There is no sense in doing a cache sync on REGCACHE_NONE regmaps.
Instead of panicking the kernel due to missing cache_ops, return an error
to client driver.

The IRAM is part of the HiFi DSP.
According to hardware specification only 32-bits write are allowed
otherwise we get a Kernel panic.
Therefore add a custom memory copy and memset functions to deal with
the above restriction.

[ Upstream commit 2e8e9a895c4589f124a37fc84d123b5114406e94 ]
The memory manager IDR is currently destroyed when user releases the
file descriptor.
However, at this point the user context might be still held, and memory
buffers might be still in use.
Later on, calls to release those buffers will fail due to not finding
their handles in the IDR, leading to a memory leak.
To avoid this leak, split the IDR destruction from the memory manager
fini, and postpone it to hpriv_release() when there is no user context
and no buffers are used.

[ Upstream commit 5f3401eeb064fab5ce50728cce46532cce7a85c5 ]
[Why]
For dual displays where pixel rate is much higher on one display,
we may get underflow when DET is evenly allocated.
[How]
Allocate less DET segments for the lower pixel rate display and
more DET segments for the higher pixel rate display

[ Upstream commit 474acc639fc8671fa4c1919d9e03253c82b6d321 ]
The call of mxc_jpeg_get_plane_size() from mxc_jpeg_dec_irq() sets
plane_no argument to 1. The compiler sees that it's possible to end up
with an access beyond the bounds of sizeimage, if mem_planes was too
large:
if (plane_no >= fmt->mem_planes) // mem_planes = 2+
return 0;
if (fmt->mem_planes == fmt->comp_planes) // comp_planes != mem_planes
return q_data->sizeimage[plane_no];
if (plane_no < fmt->mem_planes - 1) // mem_planes = 2
return q_data->sizeimage[plane_no];
comp_planes == 0 or 1 is safe. comp_planes > 2 would be out of bounds.
(This isn't currently possible given the contents of mxc_formats, though.)
Silence the warning by bounds checking comp_planes for future
robustness. Seen with GCC 13:

[ 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 3f95ecf2a3e4db09e58d307932037e8f1210d6e7 ]
Discovered Intel VSEC/DVSEC capabilities are enabled by default and only
get disabled by quirk. Instead, remove such quirks and only enable support
for capabilities that have been explicitly added to a new capabilities
field. While here, also reorder the device info structures alphabetically.

[ Upstream commit b5af48eedcb53491c02ded55d5991e03d6da6dbf ]
This fixes a use-after-free crash during rmmod.
The DRM encoder is embedded inside the larger rockchip_hdmi,
which is allocated with the component. The component memory
gets freed before the main drm device is destroyed. Fix it
by running encoder cleanup before tearing down its container.

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

[ Upstream commit e5b492c6bb900fcf9722e05f4a10924410e170c1 ]
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.

[ Upstream commit 37403ced9f2873fab7f39ab4ac963bbb33fb0bc0 ]
[Why]
Observing underflow on dcn30+ system config at 4k144hz
[How]
We set the UCLK hardmax on AC/DC switch if softmax is enabled
and also on boot. While booting up the UCLK Hardmax is set
to softmax before the init sequence and the init sequence
resets the hardmax to UCLK max which enables P-state switching.
Just added a conditional check to avoid setting hardmax on init.

[ Upstream commit cb949ce504e829193234e26cb3042bb448465d52 ]
VPU on MTL has hardware optimizations and does not require 10ms
D0 - D3hot transition delay imposed by PCI specification (PCIe
r6.0, sec 5.9.) .
The delay removal is traditionally done by adding PCI ID to
quirk_remove_d3hot_delay() in drivers/pci/quirks.c . But since
we do not need that optimization before driver probe and we
can better specify in the ivpu driver on what (future) hardware
use the optimization, we do not use quirk_remove_d3hot_delay()
for that.

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.

[ 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 35727af2b15d98a2dd2811d631d3a3886111312e ]
The T241 platform suffers from the T241-FABRIC-4 erratum which causes
unexpected behavior in the GIC when multiple transactions are received
simultaneously from different sources. This hardware issue impacts
NVIDIA server platforms that use more than two T241 chips
interconnected. Each chip has support for 320 {E}SPIs.
This issue occurs when multiple packets from different GICs are
incorrectly interleaved at the target chip. The erratum text below
specifies exactly what can cause multiple transfer packets susceptible
to interleaving and GIC state corruption. GIC state corruption can
lead to a range of problems, including kernel panics, and unexpected
behavior.
>From the erratum text:
"In some cases, inter-socket AXI4 Stream packets with multiple
transfers, may be interleaved by the fabric when presented to ARM
Generic Interrupt Controller. GIC expects all transfers of a packet
to be delivered without any interleaving.
The following GICv3 commands may result in multiple transfer packets
over inter-socket AXI4 Stream interface:
- Register reads from GICD_I* and GICD_N*
- Register writes to 64-bit GICD registers other than GICD_IROUTERn*
- ITS command MOVALL
Multiple commands in GICv4+ utilize multiple transfer packets,
including VMOVP, VMOVI, VMAPP, and 64-bit register accesses."
This issue impacts system configurations with more than 2 sockets,
that require multi-transfer packets to be sent over inter-socket
AXI4 Stream interface between GIC instances on different sockets.
GICv4 cannot be supported. GICv3 SW model can only be supported
with the workaround. Single and Dual socket configurations are not
impacted by this issue and support GICv3 and GICv4."
Link: https://developer.nvidia.com/docs/t241-fabric-4/nvidia-t241-fabric-4-errata.pdf
Writing to the chip alias region of the GICD_In{E} registers except
GICD_ICENABLERn has an equivalent effect as writing to the global
distributor. The SPI interrupt deactivate path is not impacted by
the erratum.
To fix this problem, implement a workaround that ensures read accesses
to the GICD_In{E} registers are directed to the chip that owns the
SPI, and disable GICv4.x features. To simplify code changes, the
gic_configure_irq() function uses the same alias region for both read
and write operations to GICD_ICFGR.

[ Upstream commit 567f97bd381fd79fa8563808118fc757cb6fa4ff ]
In current cio2-bridge, it is using the hid name to register software
node and software node will create kobject and sysfs entry according to
the node name, if there are multiple sensors and VCMs which are sharing
same HID name, it will cause the software nodes registration failure:
sysfs: cannot create duplicate filename '/kernel/software_nodes/dw9714'
...
Call Trace:
software_node_register_nodes
cio2_bridge_init
...
kobject_add_internal failed for dw9714 with -EEXIST,
don't try to register things with the same name in the same directory.
One solution is appending the sensor link(Mipi Port) in SSDB as suffix
of the node name to fix this problem.

[ Upstream commit abe4f5ae5efa6a63c7d5abfa07eb02bb56b4654e ]
After the recent backlight changes acpi_video# backlight devices are only
registered when explicitly requested from the cmdline, by DMI quirk or by
the GPU driver.
This means that we no longer get false-positive backlight control support
advertised on desktop boards.
Remove the 3 DMI quirks for desktop boards where the false-positive issue
was fixed through quirks before. Note many more desktop boards were
affected but we never build a full quirk list for this.

to play 1080p video cause underflow. According to HW SPEC,
the senario should use high voltage level.
[How]
ChromaPre value is zero when bandwidth validation.
Correct ChromaPre calculation.

[ 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.

From: Mukul Joshi <mukul.joshi@amd.com>
[ Upstream commit 318e431b306e966d2ee99e900a11bdc9a701ee83 ]
This patch enables the IH retry CAM on GFX9 series cards. This
retry filter is used to prevent sending lots of retry interrupts
in a short span of time and overflowing the IH ring buffer. This
will also help reduce CPU interrupt workload.

variable *nplanes is provided by user via system call argument. The
possible value of q_data->fmt->num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.
Fix this bug by checking *nplanes against the array size.

[ Upstream commit 4a148e9b1ee04e608263fa9536a96214d5561220 ]
This seems to be a new revision of the device. RGB controls have changed,
but this driver doesn't touch them anyway.
Fan speed control reported to be working with existing userspace (hidraw)
software, so I assume it's compatible. Fan channel count is the same.
Recently added (0x1e71, 0x2019) seems to be the same device.

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)

[ 784.906832] <TASK>
Adding function callbacks for MHI wakeup and release operations.
QCN9274 does not need wakeup/release, function callbacks are initialized
to NULL. In case of WCN7850, shadow registers are used to access rings.
Since, shadow register's offset is less than ACCESS_ALWAYS_OFF,
mhi_device_get_sync() or mhi_device_put() to wakeup
and release mhi will not be called during service ring accesses.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0-03171-QCAHKSWPL_SILICONZ-1

[ 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 91918ce88d9fef408bb12c46a27c73d79b604c20 ]
Newer Apple firmwares on chipsets without a hardware RNG require the
host to provide a buffer of 256 random bytes to the device on
initialization. This buffer is present immediately before NVRAM,
suffixed by a footer containing a magic number and the buffer length.
This won't affect chips/firmwares that do not use this feature, so do it
unconditionally for all Apple platforms (those with an Apple OTP).

[ 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.

Check that log of block size stored in the superblock has sensible
value. Otherwise the shift computing the block size can overflow leading
to undefined behavior.

[ 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.

From: Justin Tee <justin.tee@broadcom.com>
[ Upstream commit db651ec22524eb8f9c854fbb4d9acd5d7e5be9e4 ]
A fabric controller can sometimes send an RDP request right before a link
down event. Because of this outstanding RDP request, the driver does not
remove the last reference count on its ndlp causing a potential leak of RPI
resources when devloss tmo fires.
In lpfc_cmpl_els_rsp(), modify the NPIV clause to always allow the
lpfc_drop_node() routine to execute when not registered with SCSI
transport.
This relaxes the contraint that an NPIV ndlp must be in a specific state in
order to call lpfc_drop node. Logic is revised such that the
lpfc_drop_node() routine is always called to ensure the last ndlp decrement
occurs.

The value of an arithmetic expression is subject
of possible overflow due to a failure to cast operands to a larger data
type before performing arithmetic. Used macro for multiplication instead
operator for avoiding overflow.

[ Upstream commit c8384d4a51e7cb0e6587f3143f29099f202c5de1 ]
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
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.

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]

[ Upstream commit cfcdb5bad34f600aed7613c3c1a5e618111f77b7 ]
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.

To fix the issue, grab sas_dev lock when traversing the members of
sas_dev.list in dereg_device_v3_hw() and hisi_sas_release_tasks() to avoid
concurrency of adding and deleting member. When function
hisi_sas_release_tasks() calls hisi_sas_do_release_task() to free slot, the
lock cannot be grabbed again in hisi_sas_slot_task_free(), then a bool
parameter need_lock is added.

[ Upstream commit b07ffe6927c75d99af534d685282ea188d9f71a6 ]
We need to set ac_g_ex to notify the goal start used in
ext4_mb_find_by_goal. Set ac_g_ex instead of ac_f_ex in
ext4_mb_normalize_request.
Besides we should assure goal start is in range [first_data_block,
blocks_count) as ext4_mb_initialize_context does.
[ 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
ext4_get_group_no_and_offset(), which will trigger a BUG_ON later on.

[ 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.

[ Upstream commit 3fde2fe99aa6dacd4151c87382b07ce7f30f0a52 ]
According to SP800-90B, two health failures are allowed: the intermittend
and the permanent failure. So far, only the intermittent failure was
implemented. The permanent failure was achieved by resetting the entire
entropy source including its health test state and waiting for two or
more back-to-back health errors.
This approach is appropriate for RCT, but not for APT as APT has a
non-linear cutoff value. Thus, this patch implements 2 cutoff values
for both RCT/APT. This implies that the health state is left untouched
when an intermittent failure occurs. The noise source is reset
and a new APT powerup-self test is performed. Yet, whith the unchanged
health test state, the counting of failures continues until a permanent
failure is reached.
Any non-failing raw entropy value causes the health tests to reset.
The intermittent error has an unchanged significance level of 2^-30.
The permanent error has a significance level of 2^-60. Considering that
this level also indicates a false-positive rate (see SP800-90B section 4.2)
a false-positive must only be incurred with a low probability when
considering a fleet of Linux kernels as a whole. Hitting the permanent
error may cause a panic(), the following calculation applies: Assuming
that a fleet of 10^9 Linux kernels run concurrently with this patch in
FIPS mode and on each kernel 2 health tests are performed every minute
for one year, the chances of a false positive is about 1:1000
based on the binomial distribution.
In addition, any power-up health test errors triggered with
jent_entropy_init are treated as permanent errors.
A permanent failure causes the entire entropy source to permanently
return an error. This implies that a caller can only remedy the situation
by re-allocating a new instance of the Jitter RNG. In a subsequent
patch, a transparent re-allocation will be provided which also changes
the implied heuristic entropy assessment.
In addition, when the kernel is booted with fips=1, the Jitter RNG
is defined to be part of a FIPS module. The permanent error of the
Jitter RNG is translated as a FIPS module error. In this case, the entire
FIPS module must cease operation. This is implemented in the kernel by
invoking panic().
The patch also fixes an off-by-one in the RCT cutoff value which is now
set to 30 instead of 31. This is because the counting of the values
starts with 0.

[ Upstream commit d11cef14f8146f3babd286c2cc8ca09c166295e2 ]
When f2fs tries to checkpoint during foreground gc in LFS mode, system
crash occurs due to lack of free space if the amount of dirty node and
dentry pages generated by data migration exceeds free space.
The reproduction sequence is as follows.
- 20GiB capacity block device (null_blk)
- format and mount with LFS mode
- create a file and write 20,000MiB
- 4k random write on full range of the file

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.

With below case, it can mount multi-device image w/ rw option, however
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
in f2fs_remount() w/ it in order to avoid such inconsistent mount status.
mkfs.f2fs -c /dev/zram1 /dev/zram0 -f

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.

[ Upstream commit 6efddf1e32e2a264694766ca485a4f5e04ee82a7 ]
status_resync() will calculate 'curr_resync - recovery_active' to show
user a progress bar like following:
[============>........] resync = 61.4%
'curr_resync' and 'recovery_active' is updated in md_do_sync(), and
status_resync() can read them concurrently, hence it's possible that
'curr_resync - recovery_active' can overflow to a huge number. In this
case status_resync() will be stuck in the loop to print a large amount
of '=', which will end up soft lockup.
Fix the problem by setting 'resync' to MD_RESYNC_ACTIVE in this case,
this way resync in progress will be reported to user.

[ Upstream commit c54876cd5961ce0f8e74807f79a6739cd6b35ddf ]
With the multiplexed ndo_setup_tc() model which lacks a first-class
struct netlink_ext_ack * argument, the only way to pass the netlink
extended ACK message down to the device driver is to embed it within the
offload structure.
Do this for struct tc_mqprio_qopt_offload and struct tc_taprio_qopt_offload.
Since struct tc_taprio_qopt_offload also contains a tc_mqprio_qopt_offload
structure, and since device drivers might effectively reuse their mqprio
implementation for the mqprio portion of taprio, we make taprio set the
extack in both offload structures to point at the same netlink extack
message.
In fact, the taprio handling is a bit more tricky, for 2 reasons.
First is because the offload structure has a longer lifetime than the
extack structure. The driver is supposed to populate the extack
synchronously from ndo_setup_tc() and leave it alone afterwards.
To not have any use-after-free surprises, we zero out the extack pointer
when we leave taprio_enable_offload().
The second reason is because taprio does overwrite the extack message on
ndo_setup_tc() error. We need to switch to the weak form of setting an
extack message, which preserves a potential message set by the driver.

[ 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 d066a530af8e1833c7ea2cef7784004700c85f79 ]
If adding a key to firmware fails we leak the allocated ptk_pn.
This shouldn't happen in practice, but we should still fix it.

[ Upstream commit a06bfb3c9f69f303692cdae87bc0899d2ae8b2a6 ]
When max virtual ap interfaces are configured in all the bands with
ACS and hostapd restart is done every 60s, a crash is observed at
random times.
In this certain scenario, a fragmented packet is received for
self peer, for which rx_tid and rx_frags are not initialized in
datapath. While handling this fragment, crash is observed as the
rx_frag list is uninitialised and when we walk in
ath11k_dp_rx_h_sort_frags, skb null leads to exception.
To address this, before processing received fragments we check
dp_setup_done flag is set to ensure that peer has completed its
dp peer setup for fragment queue, else ignore processing the
fragments.

[ Upstream commit 03eb52dd78cab08f13925aeec8315fbdbcba3253 ]
Issue: Though the Netgear AXE3000 (A8000) is based on the mt7921
chipset because of the unique USB VID:PID combination this device
does not initialize/register. Thus making it not plug and play.
Fix: Adds support for the Netgear AXE3000 (A8000) based on the Mediatek
mt7921au chipset. The method of action is adding the USD VID/PID
pair to the mt7921u_device_table[] array.
Notes: A retail sample of the Netgear AXE3000 (A8000) yeilds the following
from lsusb D 0846:9060 NetGear, Inc. Wireless_Device. This pair
0846:9060 VID:PID has been reported by other users on Github.

[ Upstream commit b2bc600cced23762d4e97db8989b18772145604f ]
For MLO, we cannot use vif->bss_conf.chandef.chan->band, since
that will lead to a NULL-ptr dereference as bss_conf isn't used.
However, in case of real MLO, we also need to take both LMACs
into account if they exist, since the station might be active
on both LMACs at the same time.

[ 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 leak was verified to be real by unloading the driver, which resulted
in a dangling pointer to the allocation.
The allocated memory is freed in rtw_usb_intf_deinit().

[ 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.

[ Upstream commit 8194f1ef5a815aea815a91daf2c721eab2674f1f ]
Some adapters (e.g. RTL8723CS) advertise that they have more than
2 pages for local ext features, but they don't support any features
declared in these pages. RTL8723CS reports max_page = 2 and declares
support for sync train and secure connection, but it responds with
either garbage or with error in status on corresponding commands.

[ Upstream commit c0123cb6c4c7fc2a42ead6cd7d3e82b8e1c25c6f ]
The Realtek RTL8723CS is a SDIO WiFi chip. It also contains a Bluetooth
module which is connected via UART to the host.
It shares lmp subversion with 8703B, so Realtek's userspace
initialization tool (rtk_hciattach) differentiates varieties of RTL8723CS
(CG, VF, XX) with RTL8703B using vendor's command to read chip type.
Also this chip declares support for some features it doesn't support
so add a quirk to indicate that these features are broken.

[ Upstream commit 253cf30e8d3d001850a95c4729d668f916b037ab ]
The btrtl_set_quirks() has accessed btrtl_dev->ic_info->lmp_subver since
b8e482d02513. However, if installing a Realtek Bluetooth controller
without the driver supported, it will hit the NULL point accessed.
Add a check for NULL to avoid the Kernel Oops.

Basically all Intel controllers support both Central/Peripheral
LE states.
This patch enables the LE States quirk by default on all
Solar and Magnertor Intel controllers.

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 91b6d02ddcd113352bdd895990b252065c596de7 ]
The ATS2851 based controller advertises support for command "LE Set Random
Private Address Timeout" but does not actually implement it, impeding the
controller initialization.
Add the quirk HCI_QUIRK_BROKEN_SET_RPA_TIMEOUT to unblock the controller
initialization.

[ Upstream commit c3388ddc74a863466c7c3fa24d3a9cea9c9bca53 ]
I recently tested several old MacBooks and as far as I can tell, all
MacBooks that have an ISO keyboard have the tilde key quirk:
Product Model Year System CPU Shape Labels Country Quirky
============================================================================
05ac:021b A1181 2006 MacBook2,1 T5600 ISO British 13 Yes
05ac:021b A1181 2007 MacBook2,1 T7200 ISO Québécois 13 Yes
05ac:0229 A1181 2007 MacBook4,1 T8300 ANSI Usonian 33 No
05ac:022a A1181 2007 MacBook4,1 T8100 ISO English 13 Yes
05ac:022a A1181 2007 MacBook5,2 P7350 ISO Québécois 13 Yes
05ac:0237 A1278 2008 MacBook5,1 P7350 ISO Dutch 13 Yes
05ac:0237 A1278 2009 MacBook5,5 P7550 ISO British 13 Yes
The model number and year are from the laptop case. Since Apple printed
the same model and year on many different laptops, the system name (as
reported in the SMBIOS tables) and CPU form a more precise identifier.

From: Lorenzo Bianconi <lorenzo@kernel.org>
[ Upstream commit db3c490503bee4d0611f9fc17fcd8cfe6fcdbcad ]
During digital filters settling time the driver is expected to drop
samples since they can be corrupted. Introduce the capability to drop
a given number of samples according to the configured ODR.
Add sample_to_discard for LSM6DSM-like sensors since new generation
devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are
masked in hw with values greather than 0x7ffd so the driver can easily
discard them.
I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since
I do not have any sample for testing at the moment.

[ Upstream commit 752cbd8f191678e86aa754f795546b7f06b7f171 ]
Initialize the module parameters, read_timeout and write_timeout once in
init().
Module parameters can only be set once and cannot be modified later, so we
don't need to evaluate them again when passing the parameters to
wait_event_interruptible_timeout().
Convert datatype of {read,write}_timeout from 'int' to 'long int' because
implicit conversion of 'long int' to 'int' in statement
'{read,write}_timeout = MAX_SCHEDULE_TIMEOUT' results in an overflow.
Change format specifier for {read,write}_timeout from %i to %li.

[ Upstream commit 944e7deb4238d10cd16905474574236ac8a8e847 ]
xhci MSI setup is currently done at the same time as xHC host is started
in xhci_run(). This couples the generic xhci code with PCI, and will
reconfigure MSI/MSIX interrupts every time xHC is started.
Decouple MSI/MSIX configuration from generic xhci code by moving MSI/MSIX
part to a PCI specific xhci_pci_run() function overriding xhci_run().
This allows us to remove unnecessay MSI/MSIX reconfiguration done every
time PCI xhci resumes from suspend. i.e. remove the xhci_cleanup_msix()
call from xhci_resume() and the xhci_try_enale_msi() call in xhci_run()
called a bit later by xhci_resume()

[ 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

[ Upstream commit 5b3691d15e04b6d5a32c915577b8dbc5cfb56382 ]
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.

[ 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).

From: Samuel Čavoj <samuel@cavoj.net>
[ Upstream commit 326e1c208f3f24d14b93f910b8ae32c94923d22c ]
On some ACPI platforms (namely the ASUS Zenbook UM325) the _DSM method must
not be called after a notification is received but instead the mailbox
should be read immediately from RAM. This is because the ACPI interrupt
handler destroys the CCI in ERAM after copying to system memory, and when
_DSM is later called to perform a second copy, it retrieves a garbage
value.
Instead, the _DSM(read) method should only be called when necessary, i.e.
for polling the state after reset and for retrieving the version. Other
reads should not call _DSM and only peek into the RAM region.
This adds a separate read operation for the Zenbook that syncs the
ACPI mailbox only with polled commands.

pheonix platforms on some machines. Since we have same PCI id
used for probing, add check for machine configuration flag to
avoid conflict with newer pci drivers. Such machine flag has
been initialized via dmi match on few Chrome machines. If no
flag is specified probe and register older platform device.

[ Upstream commit bea407a427baa019758f29f4d31b26f008bb8cc6 ]
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.

[ 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.

[ Upstream commit 857d423c74228cfa064f79ff3a16b163fdb8d542 ]
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

[ Upstream commit 617955ca6e275c4dd0dcf5316fca7fc04a8f2fe6 ]
The EFI stub must not use any KASAN instrumented code as the kernel
proper did not initialize the thread pointer and the mapping for the
KASAN shadow region.
Avoid using the generic strcmp function, instead use the one in
drivers/firmware/efi/libstub/string.c.

[ 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:
drivers/infiniband/core/user_mad.c:564:50: warning: array subscript ‘struct ib_rmpp_mad[0]’ is partly outside array bounds of ‘unsigned char[140]’ [-Warray-bounds=]

There is a 'malloc' call in vcpu_save_state function, 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.

[ 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.

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 4f082a7531223a438c757bb20e304f4c941c67a8 ]
This combines the overflow and boundary check so that all attribute size
will be properly examined while enumerating them.

[ 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.

[ 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 ce38f3fc0f87a358a9560a3815265a94f1b38c37 ]
x86 ACPI boards which ship with only Android as their factory image may
have pretty broken ACPI tables. This includes broken _AEI ACPI GPIO event
handlers, which are normally used to listen to the micro-USB ID pin and:
1. Switch the USB-mux to the host / device USB controllers
2. Disable Vbus path before enabling the 5V boost (AXP reg 0x30 bit 7)
3. Turn 5V Vboost on / off
On non broken systems where this is not done through an ACPI GPIO event
handler, there is an ACPI INT3496 device describing the involved GPIOs
which are handled by the extcon-intel-int3496 driver; and axp288-charger.ko
listens to this extcon-device and disables the Vbus path when necessary.
On x86 Android boards, with broken ACPI GPIO event handlers, these are
disabled by acpi_quirk_skip_gpio_event_handlers() and an intel-int3496
extcon device is manually instantiated by x86-android-tablets.ko .
Add support to the axp288-charger code for this setup, so that it
properly disables the Vbus path when necessary. Note this uses
acpi_quirk_skip_gpio_event_handlers() to identify these systems,
to avoid the need to add a separate DMI match table for this.

[ Upstream commit ed4b0661cce119870edb1994fd06c9cbc1dc05c3 ]
pcie_relaxed_ordering_enabled() check was added to avoid a syndrome when
creating a MKey with relaxed ordering (RO) enabled when the driver's
relaxed_ordering_{read,write} HCA capabilities are out of sync with FW.
While this can happen with relaxed_ordering_read, it can't happen with
relaxed_ordering_write as it's set if the device supports RO write,
regardless of RO in PCI config space, and thus can't change during
runtime.
Therefore, drop the pcie_relaxed_ordering_enabled() check for
relaxed_ordering_write while keeping it for relaxed_ordering_read.
Doing so will also allow the usage of RO write in VFs and VMs (where RO
in PCI config space is not reported/emulated properly).

[ Upstream commit 64042c28c3bb6729df8e2fda89bc7ebbe3790907 ]
RK3588 has a couple of hardware blocks called Native Interface Unit
(NIU) that gate the clocks to devices behind them. Effectively this
means that some clocks require two parent clocks being enabled.
Downstream implemented this by using a separate clock driver
("clk-link") for them, which enables the second clock using PM
framework.
In the upstream kernel we are currently missing support for the second
parent. The information about it is in the GATE_LINK() macro as
linkname, but that is not used. Thus the second parent clock is not
properly enabled. So far this did not really matter, since these clocks
are mostly required for the more advanced IP blocks, that are not yet
supported upstream. As this is about to change we need a fix. There
are three options available:
1. Properly implement support for having two parent clocks in the
clock framework.
2. Mark the affected clocks CLK_IGNORE_UNUSED, so that they are not
disabled. This wastes some power, but keeps the hack contained
within the clock driver. Going from this to the first solution
is easy once that has been implemented.
3. Enabling the extra clock in the consumer driver. This leaks some
implementation details into DT.
This patch implements the second option as an intermediate solution
until the first one is available. I used an alias for CLK_IS_CRITICAL,
so that it's easy to see which clocks are not really critical once
the clock framework supports a better way to implement this.

+ * Unit (NIU), which gates clocks to devices behind them. These effectively
+ * need two parent clocks.
+ *
+ * Downstream enables the linked clock via runtime PM whenever the gate is
+ * enabled. This implementation uses separate clock nodes for each of the
+ * linked gate clocks, which leaks parts of the clock tree into DT.
+ *
+ * The GATE_LINK macro instead takes the second parent via 'linkname', but
+ * ignores the information. Once the clock framework is ready to handle it, the
+ * information should be passed on here. But since these clocks are required to
+ * access multiple relevant IP blocks, such as PCIe or USB, we mark all linked
+ * clocks critical until a better solution is available. This will waste some
+ * power, but avoids leaking implementation details into DT or hanging the
+ * system.

Use devm_kasprintf() instead of kasprintf() to avoid any potential
leaks. At the moment drivers have no remove functionality hence
there is no need for fixes tag.
While at it, switch to use devm_kasprintf_strarray().

[ 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 e9537962519e88969f5f69cd0571eb4f6984403c ]
This reverts commit
443a98e649b4 ("soundwire: bus: use pm_runtime_resume_and_get()")
Change calls to pm_runtime_resume_and_get() back to pm_runtime_get_sync().
This fixes a usage count underrun caused by doing a pm_runtime_put() even
though pm_runtime_resume_and_get() returned an error.
The three affected functions ignore -EACCES error from trying to get
pm_runtime, and carry on, including a put at the end of the function.
But pm_runtime_resume_and_get() does not increment the usage count if it
returns an error. So in the -EACCES case you must not call
pm_runtime_put().
The documentation for pm_runtime_get_sync() says:
"Consider using pm_runtime_resume_and_get() ... as this is likely to
result in cleaner code."
In this case I don't think it results in cleaner code because the
pm_runtime_put() at the end of the function would have to be conditional on
the return value from pm_runtime_resume_and_get() at the top of the
function.
pm_runtime_get_sync() doesn't have this problem because it always
increments the count, so always needs a put. The code can just flow through
and do the pm_runtime_put() unconditionally.

[ Upstream commit ded99b89d25fd73a1d7bd910378e0339fd9d4c4a ]
The Android Lenovo Yoga Book X90F / X90L uses the same charger / fuelgauge
setup as the already supported Windows Lenovo Yoga Book X91F/L, add
a DMI match for this to intel_cht_wc_models with driver_data
set to INTEL_CHT_WC_LENOVO_YOGABOOK1.
When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

[ 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")

Failure to add offloaded policy will cause to the following
error once user will try to reload driver.
Unregister_netdevice: waiting for eth3 to become free. Usage count = 2
This was caused by xfrm_dev_policy_add() which increments reference
to net_device. That reference was supposed to be decremented
in xfrm_dev_policy_free(). However the latter wasn't called.

[ 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 e9d9ce5462fecdeefec87953de71df4d025cbc72 ]
These offsets do not fall under the MDP TOP block and do not fit the
comment right above. Move them to dpu_hw_interrupts.c next to the
repsective MDP_INTF_x_OFF interrupt block offsets.

[ Upstream commit 8b409996ebdce009777dfb17e542c06f749b02d5 ]
Downstream driver uses dpu->caps->smart_dma_rev to update
sspp->cap->features with the bit corresponding to the supported SmartDMA
version. Upstream driver does not do this, resulting in SSPP subdriver
not enabling setup_multirect callback. Add corresponding SmartDMA SSPP
feature bits to dpu hw catalog.
Per Abhinav's request enable the SmartDMA features only on the platforms
where the multirect was actually verified visually (sdm845 and sm8250).
An (untested) enablement on the rest of the platforms comes in the next
patch.

[ Upstream commit dcb3f7c9042d1c1aa637b58d47bd45c00b2ac153 ]
The code doesn't use dpu_caps::smart_dma_rev field. It checks if the
corresponding feature is enabled in the SSPP features. Drop the
smart_dma_rev field completely.

These blocks are of variable length on different SoCs. Set the
correct values where I was able to retrieve it from downstream
DTs and leave the old defaults (0x1c8) otherwise.

[ Upstream commit 8399a5ff18dc634d3245d993ee8a906b5c6ffba3 ]
These blocks are of variable length on different SoCs. Set the
correct values where I was able to retrieve it from downstream
DTs and leave the old defaults (0x280) otherwise.

[ Upstream commit fbbd8cce803a2ca86ae20fe37b1642571e9dd971 ]
UBWC and highest bank settings differ slightly between different DPU
units of the same generation, while the dpu_caps and dpu_mdp_cfg are
much more stable. To ease configuration reuse move ubwc_swizzle and
highest_bank_bit data to separate structure.

[ Upstream commit 701f69183d4d52533fb2af0d6948b7d1b00d1a09 ]
SM8550 exclusively has a DITHER sub-block inside the PINGPONG block and
no other registers, hence the DITHER name of the macro and a
corresponding PINGPONG block length of zero. However, the PP_BLK_ macro
name was typo'd to DIPHER rather than DITHER.

[ Upstream commit 17955aba7877a4494d8093ae5498e19469b01d57 ]
There is error message when defer probe happens:
fsl-micfil-dai 30ca0000.micfil: Unbalanced pm_runtime_enable!
Fix the error handler with pm_runtime_enable and add
fsl_micfil_remove() for pm_runtime_disable.

[ 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 3d776e31c841ba2f69895d2255a49320bec7cea6 ]
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 68dc6c2d5eec45515855cce99256162f45651a0b ]
For errors after msm_submitqueue_get(), we need to drop the submitqueue
reference. Additionally after get_unused_fd() we need to drop the fd.
The ordering for dropping the queue lock and put_unused_fd() is not
important, so just move this all into out_post_unlock.
v2: Only drop queue ref if submit doesn't take it
v3: Fix unitialized submit ref in error path
v4: IS_ERR_OR_NULL()

[ 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).

From: Jiri Pirko <jiri@nvidia.com>
[ Upstream commit e93c9378e33f68b61ea9318580d841caa22fb9ea ]
The commit 565b4824c39f ("devlink: change port event netdev notifier
from per-net to global") changed original per-net notifier to be
per-devlink instance. That fixed the issue of non-receiving events
of netdev uninit if that moved to a different namespace.
That worked fine in -net tree.
However, later on when commit ee75f1fc44dd ("net/mlx5e: Create
separate devlink instance for ethernet auxiliary device") and
commit 72ed5d5624af ("net/mlx5: Suspend auxiliary devices only in
case of PCI device suspend") were merged, a deadlock was introduced
when removing a namespace with devlink instance with another nested
instance.
Here there is the bad flow example resulting in deadlock with mlx5:
net_cleanup_work -> cleanup_net (takes down_read(&pernet_ops_rwsem) ->
devlink_pernet_pre_exit() -> devlink_reload() ->
mlx5_devlink_reload_down() -> mlx5_unload_one_devl_locked() ->
mlx5_detach_device() -> del_adev() -> mlx5e_remove() ->
mlx5e_destroy_devlink() -> devlink_free() ->
unregister_netdevice_notifier() (takes down_write(&pernet_ops_rwsem)
Steps to reproduce:
$ modprobe mlx5_core
$ ip netns add ns1
$ devlink dev reload pci/0000:08:00.0 netns ns1
$ ip netns del ns1
Resolve this by converting the notifier from per-devlink instance to
a static one registered during init phase and leaving it registered
forever. Use this notifier for all devlink port instances created
later on.
Note what a tree needs this fix only in case all of the cited fixes
commits are present.

[ 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.

[ Upstream commit 0b01db274028f5acd207332686ffc92ac77491ac ]
Introduce the W/A for packet errors seen with short cables (<1m) between
two DP83867 PHYs.
The W/A recommended by DM requires FFE Equalizer Configuration tuning by
writing value 0x0E81 to DSP_FFE_CFG register (0x012C), surrounded by hard
and soft resets as follows:
write_reg(0x001F, 0x8000); //hard reset
write_reg(DSP_FFE_CFG, 0x0E81);
write_reg(0x001F, 0x4000); //soft reset
Since DP83867 PHY DM says "Changing this register to 0x0E81, will not
affect Long Cable performance.", enable the W/A by default.

This code was supposed to return an error code if init_stream()
failed, but it instead freed dg00x->rx_stream and returned success.
This potentially leads to a use after free.

[ Upstream commit 9113302bb43cf7a6d5a414d49b29478e57451c86 ]
As not all ICE_TX_FLAGS_* fit in current 16-bit limited
tx_flags field that was introduced in the Fixes commit,
VLAN-related information would be discarded completely.
As such, creating a vlan and trying to run ping through
would result in no traffic passing.
Fix that by refactoring tx_flags variable into flags only and
a separate variable that holds VLAN ID. As there is some space left,
type variable can fit between those two. Pahole reports no size
change to ice_tx_buf struct.

[ 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().

'port->membase' from of_iomap() not released on lines: 631.
In arc_serial_probe(), if uart_add_one_port() fails,
port->membase is not released, which would cause a resource leak.

[ Upstream commit ebe9bc50952757b4b25eaf514da7c464196c9606 ]
stp_set_state() should actually allow receiving BPDU while in LEARNING
mode which is not the case. Additionally, the BLOCKEN bit does not
actually forbid sending forwarded frames from that port. To fix this, add
a5psw_port_tx_enable() function which allows to disable TX. However, while
its name suggest that TX is totally disabled, it is not and can still
allow to send BPDUs even if disabled. This can be done by using forced
forwarding with the switch tagging mechanism but keeping "filtering"
disabled (which is already the case in the rzn1-a5sw tag driver). With
these fixes, STP support is now functional.

[ Upstream commit ec52b69c046a6219011af780aca155a96719637b ]
When ports are in standalone mode, they should have learning disabled to
avoid adding new entries in the MAC lookup table which might be used by
other bridge ports to forward packets. While adding that, also make sure
learning is enabled for CPU port.

[ 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.

The timeout of the cmdq reset command has been increased to
resolve the reset timeout issue in the full VF scenario.
The timeout of other cmdq commands remains unchanged.

[ 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 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.

[ Upstream commit 4708449eafe60742334606168926985798c9c9b8 ]
The commands in sof_ipc_dai_config.flags are encoded as bits:
1 (bit0) - hw_params
2 (bit1) - hw_free
4 (bit2) - pause
These are commands, they cannot be combined as one would assume, for
example
3 (bit0 | bit1) is invalid.
This can happen right at the second start of a stream as at the end of the
first stream we set the hw_free command (bit1) and on the second start we
would OR on top of it the hw_params (bit0).

From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit a93d2afd3f77a7331271a0f25c6a11003db69b3c ]
When devm runs function in the "remove" path for a device it runs them
in the reverse order. That means that if you have parts of your driver
that aren't using devm or are using "roll your own" devm w/
devm_add_action_or_reset() you need to keep that in mind.
The mt8186 audio driver didn't quite get this right. Specifically, in
mt8186_init_clock() it called mt8186_audsys_clk_register() and then
went on to call a bunch of other devm function. The caller of
mt8186_init_clock() used devm_add_action_or_reset() to call
mt8186_deinit_clock() but, because of the intervening devm functions,
the order was wrong.
Specifically at probe time, the order was:
1. mt8186_audsys_clk_register()
2. afe_priv->clk = devm_kcalloc(...)
3. afe_priv->clk[i] = devm_clk_get(...)
At remove time, the order (which should have been 3, 2, 1) was:
1. mt8186_audsys_clk_unregister()
3. Free all of afe_priv->clk[i]
2. Free afe_priv->clk
The above seemed to be causing a use-after-free. Luckily, it's easy to
fix this by simply using devm more correctly. Let's move the
devm_add_action_or_reset() to the right place. In addition to fixing
the use-after-free, code inspection shows that this fixes a leak
(missing call to mt8186_audsys_clk_unregister()) that would have
happened if any of the syscon_regmap_lookup_by_phandle() calls in
mt8186_init_clock() had failed.

Topology could have more instances of the tokens being searched for than
the number of sets that need to be copied. Stop copying token after the
limit of number of token instances has been reached. This worked before
only by chance as we had allocated more size for the tuples array than
the number of actual tokens being parsed.

[ Upstream commit c83b49383b595be50647f0c764a48c78b5f3c4f8 ]
As the call trace shows, skb_panic was caused by wrong skb->mac_header
in nsh_gso_segment():

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

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.

add tipc_bearer_min_mtu() to calculate min mtu accordingly.

[ 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.

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 7255355a0636b4eff08d5e8139c77d98f151c4fc ]
Fix the current implementation that causes ice_trigger_vf_reset()
to start resetting the VF even when the VF-NIC is still initializing.
When we reset NIC with ice driver it can interfere with
iavf-vf initialization e.g. during consecutive resets induced by ice
iavf ice

| ice resets vf
iavf |

start |
|<-----------------|
| ice resets vf
| causing iavf
| initialization
| error
| |
iavf
reset
end
This leads to a series of -53 errors
(failed to init adminq) from the IAVF.
Change the state of the vf_state field to be not active when the IAVF
is still initializing. Make sure to wait until receiving the message on
the message box to ensure that the vf is ready and initializded.
In simple terms we use the ACTIVE flag to make sure that the ice
driver knows if the iavf is ready for another reset

[ Upstream commit 7dcbdf29282fbcdb646dc785e8a57ed2c2fec8ba ]
When the user disables rxvlan offloading and then changes the number of
channels, all VLAN ports are unable to receive traffic.
Changing the number of channels triggers a VFR reset. During re-init, when
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS is received, we do:
1 - set the IAVF_FLAG_SETUP_NETDEV_FEATURES flag
2 - call
iavf_set_vlan_offload_features(adapter, 0, netdev->features);
The second step sends to the PF the __default__ features, in this case
aq_required |= IAVF_FLAG_AQ_ENABLE_CTAG_VLAN_STRIPPING
While the first step forces the watchdog task to call
netdev_update_features() -> iavf_set_features() ->
iavf_set_vlan_offload_features(adapter, netdev->features, features).
Since the user disabled the "rxvlan", this sets:
aq_required |= IAVF_FLAG_AQ_DISABLE_CTAG_VLAN_STRIPPING
When we start processing the AQ commands, both flags are enabled. Since we
process DISABLE_XTAG first then ENABLE_XTAG, this results in the PF
enabling the rxvlan offload. This breaks all communications on the VLAN
net devices.
Fix by removing the call to iavf_set_vlan_offload_features() (second
step). Calling netdev_update_features() from watchdog task is enough for
both init and reset paths.

[ Upstream commit ef6e1997da63ad0ac3fe33153fec9524c9ae56c9 ]
In the function ieee80211_tx_dequeue() there is a particular locking
sequence:
begin:
spin_lock(&local->queue_stop_reason_lock);
q_stopped = local->queue_stop_reasons[q];
spin_unlock(&local->queue_stop_reason_lock);
However small the chance (increased by ftracetest), an asynchronous
interrupt can occur in between of spin_lock() and spin_unlock(),
and the interrupt routine will attempt to lock the same
&local->queue_stop_reason_lock again.
This will cause a costly reset of the CPU and the wifi device or an
altogether hang in the single CPU and single core scenario.
The only remaining spin_lock(&local->queue_stop_reason_lock) that
did not disable interrupts was patched, which should prevent any
deadlocks on the same CPU/core and the same wifi device.
This is the probable trace of the deadlock:

[ Upstream commit 13ad2b1eeacd48ec0f31f55964e6dc7dfc2c0299 ]
'changed' can be OR'ed with BSS_CHANGED_EHT_PUNCTURING which is larger than
an u32.
So, turn 'changed' into an u64 and update ieee80211_set_after_csa_beacon()
accordingly.
In the commit in Fixes, only ieee80211_start_ap() was updated.

[ 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 d3ae69180bbd74bcbc03a2b6d10ed7eccbe98c23 ]
The DBGI dump is (unsurprisingly) of type DBGI, not SRAM.
This leads to bad register accesses because the union is
built differently, there's no allocation ID, and thus the
allocation ID ends up being 0x8000.
Note that this was already wrong for DRAM vs. SMEM since
they use different parts of the union, but the allocation
ID is at the same place, so it worked.
Fix all of this but set the allocation ID in a way that
the offset calculation ends up without any offset.

[ 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.

From: Michael Kelley <mikelley@microsoft.com>
[ 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 d6352dae0903fe8beae4c007dc320e9e9f1fed45 ]
'__net_initdata' becomes a no-op with CONFIG_NET_NS=y, but when this
option is disabled it becomes '__initdata', which means the data can be
freed after the initialization phase. This annotation is obviously
incorrect for the devlink net device notifier block which is still
registered after the initialization phase [1].
Fix this crash by removing the '__net_initdata' annotation.

[ Upstream commit 82b2bc279467c875ec36f8ef820f00997c2a4e8e ]
syzkaller reported [0] memory leaks of sk and skb related to the TUN
device with no repro, but we can reproduce it easily with:
struct ifreq ifr = {}
int fd_tun, fd_tmp;
char buf[4] = {};
fd_tun = openat(AT_FDCWD, "/dev/net/tun", O_WRONLY, 0);
ifr.ifr_flags = IFF_TUN | IFF_NAPI | IFF_MULTI_QUEUE;
ioctl(fd_tun, TUNSETIFF, &ifr);
ifr.ifr_flags = IFF_DETACH_QUEUE;
ioctl(fd_tun, TUNSETQUEUE, &ifr);
fd_tmp = socket(AF_PACKET, SOCK_PACKET, 0);
ifr.ifr_flags = IFF_UP;
ioctl(fd_tmp, SIOCSIFFLAGS, &ifr);
write(fd_tun, buf, sizeof(buf));
close(fd_tun);
If we enable NAPI and multi-queue on a TUN device, we can put skb into
tfile->sk.sk_write_queue after the queue is detached. We should prevent
it by checking tfile->detached before queuing skb.
Note this must be done under tfile->sk.sk_write_queue.lock because write()
and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise, there would
be a small race window:
write() ioctl(IFF_DETACH_QUEUE)
`- tun_get_user `- __tun_detach
|- if (tfile->detached) |- tun_disable_queue
| `-> false | `- tfile->detached = tun
| `- tun_queue_purge
|- spin_lock_bh(&queue->lock)
`- __skb_queue_tail(queue, skb)
Another solution is to call tun_queue_purge() when closing and
reattaching the detached queue, but it could paper over another
problems. Also, we do the same kind of test for IFF_NAPI_FRAGS.

cas_saturn_firmware_init() allocates some memory using vmalloc(). This
memory is freed in the .remove() function but not it the error handling
path of the probe.
Add the missing vfree() to avoid a memory leak, should an error occur.

[ 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 60829145f1e2650b31ebe6a0ec70a9725b38fa2c ]
In suspend and resume cycle, the removal and rescan of device ends
up in NULL pointer dereference.
During driver initialization, if the ipc_imem_wwan_channel_init()
fails to get the valid device capabilities it returns an error and
further no resource (wwan struct) will be allocated. Now in this
situation if driver removal procedure is initiated it would result
in NULL pointer exception since unallocated wwan struct is dereferenced
inside ipc_wwan_deinit().
ipc_imem_run_state_worker() to handle the called functions return value
and to release the resource in failure case. It also reports the link
down event in failure cases. The user space application can handle this
event to do a device reset for restoring the device communication.

[ Upstream commit c46e78ba9a7a09da4f192dc8df15c4e8a07fb9e0 ]
The XPCS expects clause 73 (copper backplane) autoneg to follow the
ethtool autoneg bit. It actually did that until the blamed
commit inaptly replaced state->an_enabled (coming from ethtool) with
phylink_autoneg_inband() (coming from the device tree or struct
phylink_config), as part of an unrelated phylink_pcs API conversion.
Russell King suggests that state->an_enabled from the original code was
just a proxy for the ethtool Autoneg bit, and that the correct way of
restoring the functionality is to check for this bit in the advertising
mask.

[ Upstream commit 9ba9485b87ac97fd159abdb4cbd53099bc9f01c6 ]
The cited commit added a stray colon to the 'v' option. That makes the
option work incorrectly.
ex:
tools/testing/selftests/net# ./fib_nexthops.sh -v
(should enable verbose mode, instead it shows help text due to missing arg)

nft_trans_FOO objects all share a common nft_trans base structure, but
trailing fields depend on the real object size. Access is only safe after
trans->msg_type check.
Check for rule type first. Found by code inspection.

[ 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 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()

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.

From: Roger Quadros <rogerq@kernel.org>
commit c8540870af4ce6ddeb27a7bb5498b75fb29b643c upstream.
Prevent -ETIMEDOUT error on .suspend().
e.g. If gadget driver is loaded and we are connected to a USB host,
all transfers must be stopped before stopping the controller else
we will not get a clean stop i.e. dwc3_gadget_run_stop() will take
several seconds to complete and will return -ETIMEDOUT.
Handle error cases properly in dwc3_gadget_suspend().
Simplify dwc3_gadget_resume() by using the introduced helper function.

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.

From: Konrad Gräfe <k.graefe@gateware.de>
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.
Fixes: d1658268e439 ("usb: pci-quirks: disable D3cold on xhci suspend for s2idle on AMD Renoir")

From: Mathias Nyman <mathias.nyman@linux.intel.com>
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.

From: Takashi Iwai <tiwai@suse.de>
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.

commit 60fc756fc8e6954a5618eecac73b255d651602e4 upstream.
The probe() id argument may be NULL in 2 scenarios:
1. brcmf_pcie_pm_leave_D3() calling brcmf_pcie_probe() to reprobe
the device.
2. If a user tries to manually bind the driver from sysfs then the sdio /
pcie / usb probe() function gets called with NULL as id argument.
1. Is being hit by users causing the following oops on resume and causing
wifi to stop working:
BUG: kernel NULL pointer dereference, address: 0000000000000018

<snip>
Fix this by checking for id being NULL.
In the PCI and USB cases try a manual lookup of the id so that manually
binding the driver through sysfs and more importantly brcmf_pcie_probe()
on resume will work.
For the SDIO case there is no helper to do a manual sdio_device_id lookup,
so just directly error out on a NULL id there.

commit 8e4942db5f5ed7b7d9690d93235b3ca49c5c59ce upstream.
qsel_to_ep[] can be assigned negative value, so change type from 'u8' to
'int'. Otherwise, Smatch static checker warns:

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.
Fixes: 9e31678fb403 ("SMB3: fix lease break timeout when multiple deferred close handles for the same file.")

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.
Fixes: 9e31678fb403 ("SMB3: fix lease break timeout when multiple deferred close handles for the same file.")

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 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.

From: Oliver Upton <oliver.upton@linux.dev>
commit 1f0f4a2ef7a5693b135ce174e71f116db4bd684d upstream.
Until now, the page table walker counted increments to the PA and IPA
of a walk in two separate places. While the PA is incremented as soon as
a leaf PTE is installed in stage2_map_walker_try_leaf(), the IPA is
actually bumped in the generic table walker context. Critically,
__kvm_pgtable_visit() rereads the PTE after the LEAF callback returns
to work out if a table or leaf was installed, and only bumps the IPA for
a leaf PTE.
This arrangement worked fine when we handled faults behind the write lock,
as the walker had exclusive access to the stage-2 page tables. However,
commit 1577cb5823ce ("KVM: arm64: Handle stage-2 faults in parallel")
started handling all stage-2 faults behind the read lock, opening up a
race where a walker could increment the PA but not the IPA of a walk.
Nothing good ensues, as the walker starts mapping with the incorrect
IPA -> PA relationship.
For example, assume that two vCPUs took a data abort on the same IPA.
One observes that dirty logging is disabled, and the other observed that
it is enabled:
vCPU attempting PMD mapping vCPU attempting PTE mapping
====================================== =====================================
/* install PMD */
stage2_make_pte(ctx, leaf);
data->phys += granule;
/* replace PMD with a table */
stage2_try_break_pte(ctx, data->mmu);
stage2_make_pte(ctx, table);
/* table is observed */
ctx.old = READ_ONCE(*ptep);
table = kvm_pte_table(ctx.old, level);
/*
* map walk continues w/o incrementing
* IPA.
*/
__kvm_pgtable_walk(..., level + 1);
Bring an end to the whole mess by using the IPA as the single source of
truth for how far along a walk has gotten. Work out the correct PA to
map by calculating the IPA offset from the beginning of the walk and add
that to the starting physical address.

commit afb2acb2e3a32e4d56f7fbd819769b98ed1b7520 upstream.
In kvm_vm_ioctl_create_vcpu(), add vcpu to vcpu_array iff it's safe to
access vcpu via kvm_get_vcpu() and kvm_for_each_vcpu(), i.e. when there's
no failure path requiring vcpu removal and destruction. Such order is
important because vcpu_array accessors may end up referencing vcpu at
vcpu_array[0] even before online_vcpus is set to 1.
When online_vcpus=0, any call to kvm_get_vcpu() goes through
array_index_nospec() and ends with an attempt to xa_load(vcpu_array, 0):
int num_vcpus = atomic_read(&kvm->online_vcpus);
i = array_index_nospec(i, num_vcpus);
return xa_load(&kvm->vcpu_array, i);
Similarly, when online_vcpus=0, a kvm_for_each_vcpu() does not iterate over
an "empty" range, but actually [0, ULONG_MAX]:
xa_for_each_range(&kvm->vcpu_array, idx, vcpup, 0, \
(atomic_read(&kvm->online_vcpus) - 1))
In both cases, such online_vcpus=0 edge case, even if leading to
unnecessary calls to XArray API, should not be an issue; requesting
unpopulated indexes/ranges is handled by xa_load() and xa_for_each_range().
However, this means that when the first vCPU is created and inserted in
vcpu_array *and* before online_vcpus is incremented, code calling
kvm_get_vcpu()/kvm_for_each_vcpu() already has access to that first vCPU.
This should not pose a problem assuming that once a vcpu is stored in
vcpu_array, it will remain there, but that's not the case:
kvm_vm_ioctl_create_vcpu() first inserts to vcpu_array, then requests a
file descriptor. If create_vcpu_fd() fails, newly inserted vcpu is removed
from the vcpu_array, then destroyed:
vcpu->vcpu_idx = atomic_read(&kvm->online_vcpus);
r = xa_insert(&kvm->vcpu_array, vcpu->vcpu_idx, vcpu, GFP_KERNEL_ACCOUNT);
kvm_get_kvm(kvm);
r = create_vcpu_fd(vcpu);
if (r < 0) {
xa_erase(&kvm->vcpu_array, vcpu->vcpu_idx);
kvm_put_kvm_no_destroy(kvm);
goto unlock_vcpu_destroy;
}
atomic_inc(&kvm->online_vcpus);
This results in a possible race condition when a reference to a vcpu is
acquired (via kvm_get_vcpu() or kvm_for_each_vcpu()) moments before said
vcpu is destroyed.

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.

commit 0257d9908d38c0b1669af4bb1bc4dbca1f273fe6 upstream.
Make mas->min and mas->max point to a node range instead of a leaf entry
range. This allows mas to still be usable after mas_empty_area() returns.
Users would get unexpected results from other operations on the maple
state after calling the affected function.
For example, x86 MAP_32BIT mmap() acts as if there is no suitable gap when
there should be one.

From: Domenico Cerasuolo <cerasuolodomenico@gmail.com>
commit 04fc7816089c5a32c29a04ec94b998e219dfb946 upstream.
The zswap writeback mechanism can cause a race condition resulting in
memory corruption, where a swapped out page gets swapped in with data that
was written to a different page.
The race unfolds like this:
1. a page with data A and swap offset X is stored in zswap
2. page A is removed off the LRU by zpool driver for writeback in
zswap-shrink work, data for A is mapped by zpool driver
3. user space program faults and invalidates page entry A, offset X is
considered free
4. kswapd stores page B at offset X in zswap (zswap could also be
full, if so, page B would then be IOed to X, then skip step 5.)
5. entry A is replaced by B in tree->rbroot, this doesn't affect the
local reference held by zswap-shrink work
6. zswap-shrink work writes back A at X, and frees zswap entry A
7. swapin of slot X brings A in memory instead of B
The fix:
Once the swap page cache has been allocated (case ZSWAP_SWAPCACHE_NEW),
zswap-shrink work just checks that the local zswap_entry reference is
still the same as the one in the tree. If it's not the same it means that
it's either been invalidated or replaced, in both cases the writeback is
aborted because the local entry contains stale data.
Reproducer:
I originally found this by running `stress` overnight to validate my work
on the zswap writeback mechanism, it manifested after hours on my test
machine. The key to make it happen is having zswap writebacks, so
whatever setup pumps /sys/kernel/debug/zswap/written_back_pages should do
the trick.
In order to reproduce this faster on a vm, I setup a system with ~100M of
available memory and a 500M swap file, then running `stress --vm 1
--vm-bytes 300000000 --vm-stride 4000` makes it happen in matter of tens
of minutes. One can speed things up even more by swinging
/sys/module/zswap/parameters/max_pool_percent up and down between, say, 20
and 1; this makes it reproduce in tens of seconds. It's crucial to set
`--vm-stride` to something other than 4096 otherwise `stress` won't
realize that memory has been corrupted because all pages would have the
same data.

commit 2fe6575924612f1014a0539ab3053b106aded926 upstream.
The script command does not support aggregation modes by itself although
that can be achieved using post-processing scripts. Because of this, it
does not allocate memory for aggregated event values.
Upon running perf stat record, the aggregation mode is set in the perf
data file. If the mode is AGGR_GLOBAL, the aggregated event values are
accessed and this leads to a segmentation fault since these were never
allocated to begin with. Set the mode to AGGR_NONE explicitly to avoid
this.
E.g.
$ perf stat record -e cycles true
$ perf script
Before:
Segmentation fault (core dumped)
After:
CPU THREAD VAL ENA RUN TIME EVENT

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.

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 4cafd0400bcb6187c0d4ab4d4b0229a89ac4f8c2 upstream.
When the MClientSnap reqeust's op is not CEPH_SNAP_OP_SPLIT the
request may still contain a list of 'split_realms', and we need
to skip it anyway. Or it will be parsed as a corrupt snaptrace.

commit 5591a051b86be170a84943698ab140342602ff7b upstream.
[why]
regGOLDEN_TSC_COUNT_LOWER/regGOLDEN_TSC_COUNT_UPPER are protected and
unaccessible under sriov.
The clock counter high bit may update during reading process.
[How]
Replace regGOLDEN_TSC_COUNT_LOWER/regGOLDEN_TSC_COUNT_UPPER with
regCP_MES_MTIME_LO/regCP_MES_MTIME_HI to get gpu clock under sriov.
Refine get gpu clock counter method to make the result more precise.

From: Alex Deucher <alexander.deucher@amd.com>
commit d5aa417808cf14c052ca042920b3c6b9f1dc6aa4 upstream.
This code was written prior to previous updates to this
logic for other chips. The RSC registers are part of
SMUIO which is an always on block so there is no need
to disable gfxoff. Additionally add the carryover and
preemption checks.
v2: rebase

commit e36ca2fad6bb4ef0603bdb5556578e9082fe0056 upstream.
When the special handling of qcom,adreno-smmu was moved into
qcom_smmu_create(), it was overlooked that we didn't have all the
required entries in qcom_smmu_impl_of_match. So we stopped getting
adreno_smmu_priv on sc7180, breaking per-process pgtables.

commit 096339ab84f36beae0b1db25e0ce63fb3873e8b2 upstream.
When DMA window is backed by 2MB TCEs, the DMA address for the mapped
page should be the offset of the page relative to the 2MB TCE. The code
was incorrectly setting the DMA address to the beginning of the TCE
range.
Mellanox driver is reporting timeout trying to ENABLE_HCA for an SR-IOV
ethernet port, when DMA window is backed by 2MB TCEs.

commit 1f7aacc5eb9ed2cc17be7a90da5cd559effb9d59 upstream.
For an SR-IOV device, while enabling DDW, a new table is created and
added at index 1 in the group. In the below 2 scenarios, the table is
incorrectly referenced at index 0 (which is where the table is for
default DMA window).
1. When adding DDW
This issue is exposed with "slub_debug". Error thrown out from
dma_iommu_dma_supported()
Warning: IOMMU offset too big for device mask
mask: 0xffffffff, table offset: 0x800000000000000
2. During Dynamic removal of the PCI device.
Error is from iommu_tce_table_put() since a NULL table pointer is
passed in.

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.

From: Michael Ellerman <mpe@ellerman.id.au>
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 35a4b8ce4ac00e940b46b1034916ccb22ce9bdef upstream.
Since commit 85e031154c7c ("powerpc/bpf: Perform complete extra passes
to update addresses"), two additional passes are performed to avoid
space and CPU time wastage on powerpc. But these extra passes led to
WARN_ON_ONCE() hits in bpf_add_extable_entry() as extable entries are
populated again, during the extra pass, without resetting the index.
Fix it by resetting entry index before repopulating extable entries,
if and when there is an additional pass.

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
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.

Formatting a thin-provisioned (ESE) device that is part of a PPRC copy
relation might fail with the following error:
dasd-eckd 0.0.f500: An error occurred in the DASD device driver, reason=09
[...]
24 Byte: 0 MSG 4, no MSGb to SYSOP
During format of an ESE disk the Release Allocated Space command is used.
A bit in the payload of the command is set that is not allowed to be set
for devices in a copy relation. This bit is set to allow the partial
release of an extent.
Check for the existence of a copy relation before setting the respective
bit.

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 2efbafb91e12ff5a16cbafb0085e4c10c3fca493 upstream.
Consider the following sequence of events:
1) A page in a PROT_READ|PROT_WRITE VMA is faulted.
2) Page migration allocates a page with the KASAN allocator,
causing it to receive a non-match-all tag, and uses it
to replace the page faulted in 1.
3) The program uses mprotect() to enable PROT_MTE on the page faulted in 1.
As a result of step 3, we are left with a non-match-all tag for a page
with tags accessible to userspace, which can lead to the same kind of
tag check faults that commit e74a68468062 ("arm64: Reset KASAN tag in
copy_highpage with HW tags only") intended to fix.
The general invariant that we have for pages in a VMA with VM_MTE_ALLOWED
is that they cannot have a non-match-all tag. As a result of step 2, the
invariant is broken. This means that the fix in the referenced commit
was incomplete and we also need to reset the tag for pages without
PG_mte_tagged.

commit c4c597f1b367433c52c531dccd6859a39b4580fb upstream.
The mte_sync_page_tags() function sets PG_mte_tagged if it initializes
page tags. Then we return to mte_sync_tags(), which sets PG_mte_tagged
again. At best, this is redundant. However, it is possible for
mte_sync_page_tags() to return without having initialized tags for the
page, i.e. in the case where check_swap is true (non-compound page),
is_swap_pte(old_pte) is false and pte_is_tagged is false. So at worst,
we set PG_mte_tagged on a page with uninitialized tags. This can happen
if, for example, page migration causes a PTE for an untagged page to
be replaced. If the userspace program subsequently uses mprotect() to
enable PROT_MTE for that page, the uninitialized tags will be exposed
to userspace.
Fix it by removing the redundant call to set_page_mte_tagged().

This patch replaces preempt_{disable, enable} with its corresponding
notrace version in rethook_trampoline_handler so no worries about stack
recursion or overflow introduced by preempt_count_{add, sub} under
fprobe + rethook context.

we have the same reason to blacklist them if rethook is used with fprobe,
since they are beyond the recursion-free region ftrace can guard.

[ Upstream commit c76c6c4ecbec0deb56a4f9e932b26866024a508f ]
Commit 62b95a7b44d1 ("ARM: 9282/1: vfp: Manipulate task VFP state with
softirqs disabled") replaced the en/disable preemption calls inside the
VFP state handling code with en/disabling of soft IRQs, which is
necessary to allow kernel use of the VFP/SIMD unit when handling a soft
IRQ.
Unfortunately, when lockdep is enabled (or other instrumentation that
enables TRACE_IRQFLAGS), the disable path implemented in asm fails to
perform the lockdep and RCU related bookkeeping, resulting in spurious
warnings and other badness.
Set let's rework the VFP entry code a little bit so we can make the
local_bh_disable() call from C, with all the instrumentations that
happen to have been configured. Calling local_bh_enable() can be done
from asm, as it is a simple wrapper around __local_bh_enable_ip(), which
is always a callable function.

[ Upstream commit 2b951b0efbaa6c805854b60c11f08811054d50cd ]
Commit c76c6c4ecbec0deb5 ("ARM: 9294/2: vfp: Fix broken softirq handling
with instrumentation enabled") updated the VFP exception entry logic to
go via a C function, so that we get the compiler's version of
local_bh_disable(), which may be instrumented, and isn't generally
callable from assembler.
However, this assumes that passing an alternative 'success' return
address works in C as it does in asm, and this is only the case if the C
calls in question are tail calls, as otherwise, the stack will need some
unwinding as well.
I have already sent patches to the list that replace most of the asm
logic with C code, and so it is preferable to have a minimal fix that
addresses the issue and can be backported along with the commit that it
fixes to v6.3 from v6.4. Hopefully, we can land the C conversion for v6.5.
So instead of passing the 'success' return address as a function
argument, pass the stack address from where to pop it so that both LR
and SP have the expected value.

I'm seeing a few build failures with Linux 6.3.4-rc1 (20efcce0526d) due to the drivers/usb/host/xhci.c driver:
drivers/usb/host/xhci.c:497:19: error: static declaration of 'xhci_try_enable_msi' follows non-static declaration
497 | static inline int xhci_try_enable_msi(struct usb_hcd *hcd)
| ^~~~~~~~~~~~~~~~~~~
In file included from drivers/usb/host/xhci.c:22:
drivers/usb/host/xhci.h:2146:5: note: previous declaration of 'xhci_try_enable_msi' was here
2146 | int xhci_try_enable_msi(struct usb_hcd *hcd);
| ^~~~~~~~~~~~~~~~~~~
Example build failure: https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/jobs/4328533790#L2178
Pipeline: https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/pipelines/875108293
Commit 78887e3e5f00 ("xhci: Avoid PCI MSI/MSIX interrupt reinitialization at resume") adds the offending code.
I'm only seeing this for the 6.3 rc.
Kind regards, Chris

Just to expand on this, the builds that are failing do _not_ have CONFIG_USB_PCI set.

We see build regressions on:
* Arm, exynos_defconfig
* MIPS, cavium_octeon_defconfig
with GCC 8 and GCC-12:
-----8<-----
/builds/linux/drivers/usb/host/xhci.c:497:19: error: static declaration of 'xhci_try_enable_msi' follows non-static declaration

Reverting "xhci: Avoid PCI MSI/MSIX interrupt reinitialization at resume" makes the build pass again.

Hi Greg,
I had the same build errors as Chris and Sudip.
6.3.4-rc1 tested with the following patch reverted

Results from Linaro’s test farm.
Regressions on arm and mips builds failed.
Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>
* arm: exynos_defconfig - build failed.
* mips: cavium_octeon_defconfig - build failed.
Build failed due to this commit,
"xhci: Avoid PCI MSI/MSIX interrupt reinitialization at resume"
upstream commit 78887e3e5f00fca305670d8f3ba3c0f42b343047
NOTE:
LTP syscalls msync04 started failing intermittently on 6.3, 6.1 and 5.15 on
arm64 devices which are using NFS mounted rootfs and external mounted drive.
Whereas on arm x15 devices it always fails from 6.3.2-rc1, 6.1.28-rc1
and 5.15.111-rc1.
