[ Upstream commit e06c9e3682f58fbeb632b7b866bb4fe66a4a4b42 ]
The Microchip LAN966x outband interrupt controller is only present on
Microchip LAN966x SoCs, and only used in PCI endpoint mode. Hence add a
dependency on MCHP_LAN966X_PCI, to prevent asking the user about this
driver when configuring a kernel without Microchip LAN966x PCIe support.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit a216542027b892e6651c1b4e076012140d04afaf ]
When COWing a relocation tree path, at relocation.c:replace_path(), we
can trigger a lockdep splat while we are in the btrfs_search_slot() call
against the relocation root. This happens in that callchain at
ctree.c:read_block_for_search() when we happen to find a child extent
buffer already loaded through the fs tree with a lockdep class set to
the fs tree. So when we attempt to lock that extent buffer through a
relocation tree we have to reset the lockdep class to the class for a
relocation tree, since a relocation tree has extent buffers that used
to belong to a fs tree and may currently be already loaded (we swap
extent buffers between the two trees at the end of replace_path()).
However we are missing calls to btrfs_maybe_reset_lockdep_class() to reset
the lockdep class at ctree.c:read_block_for_search() before we read lock
an extent buffer, just like we did for btrfs_search_slot() in commit
b40130b23ca4 ("btrfs: fix lockdep splat with reloc root extent buffers").
So add the missing btrfs_maybe_reset_lockdep_class() calls before the
attempts to read lock an extent buffer at ctree.c:read_block_for_search().
The lockdep splat was reported by syzbot and it looks like this:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit 0d85f5c2dd91df6b5da454406756f463ba923b69 ]
If while we are doing a direct IO write a transaction abort happens, we
mark all existing ordered extents with the BTRFS_ORDERED_IOERR flag (done
at btrfs_destroy_ordered_extents()), and then after that if we enter
btrfs_split_ordered_extent() and the ordered extent has bytes left
(meaning we have a bio that doesn't cover the whole ordered extent, see
details at btrfs_extract_ordered_extent()), we will fail on the following
assertion at btrfs_split_ordered_extent():
ASSERT(!(flags & ~BTRFS_ORDERED_TYPE_FLAGS));
because the BTRFS_ORDERED_IOERR flag is set and the definition of
BTRFS_ORDERED_TYPE_FLAGS is just the union of all flags that identify the
type of write (regular, nocow, prealloc, compressed, direct IO, encoded).
Fix this by returning an error from btrfs_extract_ordered_extent() if we
find the BTRFS_ORDERED_IOERR flag in the ordered extent. The error will
be the error that resulted in the transaction abort or -EIO if no
transaction abort happened.

In this case the transaction abort was due to (an injected) memory
allocation failure when attempting to allocate a new chunk.

From: Qu Wenruo <wqu@suse.com>
[ Upstream commit c9c863793395cf0a66c2778a29d72c48c02fbb66 ]
[BUG]
There is a bug report that btrfs outputs the following error message:
BTRFS info (device nvme0n1p2): qgroup scan completed (inconsistency flag cleared)
BTRFS warning (device nvme0n1p2): failed to cleanup qgroup 0/1179: -2
[CAUSE]
The error itself is pretty harmless, and the end user should ignore it.
When a subvolume is fully dropped, btrfs will call
btrfs_qgroup_cleanup_dropped_subvolume() to delete the qgroup.
However if a qgroup rescan happened before a subvolume fully dropped,
qgroup for that subvolume will not be re-created, as rescan will only
create new qgroup if there is a BTRFS_ROOT_REF_KEY found.
But before we drop a subvolume, the subvolume is unlinked thus there is no
BTRFS_ROOT_REF_KEY.
In that case, btrfs_remove_qgroup() will fail with -ENOENT and trigger
the above error message.
[FIX]
Just ignore -ENOENT error from btrfs_remove_qgroup() inside
btrfs_qgroup_cleanup_dropped_subvolume().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
[ Upstream commit e2f0943cf37305dbdeaf9846e3c941451bcdef63 ]
When we are trying to join the current transaction and if it's aborted,
we read its 'aborted' field after unlocking fs_info->trans_lock and
without holding any extra reference count on it. This means that a
concurrent task that is aborting the transaction may free the transaction
before we read its 'aborted' field, leading to a use-after-free.
Fix this by reading the 'aborted' field while holding fs_info->trans_lock
since any freeing task must first acquire that lock and set

This asserts that HUGE_MAX_HSTATE is sufficient enough preventing potential
hugetlb_max_hstate runtime overflow in hugetlb_add_hstate() thus triggering
a BUG_ON() there after.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kees Cook <kees@kernel.org>
[ Upstream commit 543841d1806029889c2f69f040e88b247aba8e22 ]
Zbigniew mentioned at Linux Plumber's that systemd is interested in
switching to execveat() for service execution, but can't, because the
contents of /proc/pid/comm are the file descriptor which was used,
instead of the path to the binary[1]. This makes the output of tools like
top and ps useless, especially in a world where most fds are opened
CLOEXEC so the number is truly meaningless.
When the filename passed in is empty (e.g. with AT_EMPTY_PATH), use the
dentry's filename for "comm" instead of using the useless numeral from
the synthetic fdpath construction. This way the actual exec machinery
is unchanged, but cosmetically the comm looks reasonable to admins
investigating things.
Instead of adding TASK_COMM_LEN more bytes to bprm, use one of the unused
flag bits to indicate that we need to set "comm" from the dentry.

exrl is present in all machines currently supported, therefore prefer
it over ex. This saves one instruction and doesn't need an additional
register to hold the address of the target instruction.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hao-ran Zheng <zhenghaoran154@gmail.com>
[ Upstream commit 5324c4e10e9c2ce307a037e904c0d9671d7137d9 ]
A data race occurs when the function `insert_ordered_extent_file_extent()`
and the function `btrfs_inode_safe_disk_i_size_write()` are executed
concurrently. The function `insert_ordered_extent_file_extent()` is not
locked when reading inode->disk_i_size, causing
`btrfs_inode_safe_disk_i_size_write()` to cause data competition when
writing inode->disk_i_size, thus affecting the value of `modify_tree`.
The specific call stack that appears during testing is as follows:
============DATA_RACE============
btrfs_drop_extents+0x89a/0xa060 [btrfs]
insert_reserved_file_extent+0xb54/0x2960 [btrfs]
insert_ordered_extent_file_extent+0xff5/0x1760 [btrfs]
btrfs_finish_one_ordered+0x1b85/0x36a0 [btrfs]
btrfs_finish_ordered_io+0x37/0x60 [btrfs]
finish_ordered_fn+0x3e/0x50 [btrfs]
btrfs_work_helper+0x9c9/0x27a0 [btrfs]
process_scheduled_works+0x716/0xf10
worker_thread+0xb6a/0x1190
kthread+0x292/0x330
ret_from_fork+0x4d/0x80
ret_from_fork_asm+0x1a/0x30
============OTHER_INFO============
btrfs_inode_safe_disk_i_size_write+0x4ec/0x600 [btrfs]
btrfs_finish_one_ordered+0x24c7/0x36a0 [btrfs]
btrfs_finish_ordered_io+0x37/0x60 [btrfs]
finish_ordered_fn+0x3e/0x50 [btrfs]
btrfs_work_helper+0x9c9/0x27a0 [btrfs]
process_scheduled_works+0x716/0xf10
worker_thread+0xb6a/0x1190
kthread+0x292/0x330
ret_from_fork+0x4d/0x80
ret_from_fork_asm+0x1a/0x30
=================================
The main purpose of the check of the inode's disk_i_size is to avoid
taking write locks on a btree path when we have a write at or beyond
EOF, since in these cases we don't expect to find extent items in the
root to drop. However if we end up taking write locks due to a data
race on disk_i_size, everything is still correct, we only add extra
lock contention on the tree in case there's concurrency from other tasks.
If the race causes us to not take write locks when we actually need them,
then everything is functionally correct as well, since if we find out we
have extent items to drop and we took read locks (modify_tree set to 0),
we release the path and retry again with write locks.
Since this data race does not affect the correctness of the function,
it is a harmless data race, use data_race() to check inode->disk_i_size.

While the root cause of the tree order corruption isn't clear, using
btrfs_duplicate_item() to copy the item and then adjusting both the key

problem.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Suleiman Souhlal <suleiman@google.com>
[ Upstream commit 108ad0999085df2366dd9ef437573955cb3f5586 ]
When steal time exceeds the measured delta when updating clock_task, we
currently try to catch up the excess in future updates.
However, this results in inaccurate run times for the future things using
clock_task, in some situations, as they end up getting additional steal
time that did not actually happen.
This is because there is a window between reading the elapsed time in
update_rq_clock() and sampling the steal time in update_rq_clock_task().
If the VCPU gets preempted between those two points, any additional
steal time is accounted to the outgoing task even though the calculated
delta did not actually contain any of that "stolen" time.
When this race happens, we can end up with steal time that exceeds the
calculated delta, and the previous code would try to catch up that excess
steal time in future clock updates, which is given to the next,
incoming task, even though it did not actually have any time stolen.
This behavior is particularly bad when steal time can be very long,
which we've seen when trying to extend steal time to contain the duration
that the host was suspended [0]. When this happens, clock_task stays
frozen, during which the running task stays running for the whole
duration, since its run time doesn't increase.
However the race can happen even under normal operation.
Ideally we would read the elapsed cpu time and the steal time atomically,
to prevent this race from happening in the first place, but doing so
is non-trivial.
Since the time between those two points isn't otherwise accounted anywhere,
neither to the outgoing task nor the incoming task (because the "end of
outgoing task" and "start of incoming task" timestamps are the same),
I would argue that the right thing to do is to simply drop any excess steal
time, in order to prevent these issues.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Juri Lelli <juri.lelli@redhat.com>
[ Upstream commit d4742f6ed7ea6df56e381f82ba4532245fa1e561 ]
For hotplug operations, DEADLINE needs to check that there is still enough
bandwidth left after removing the CPU that is going offline. We however
fail to do so currently.
Restore the correct behavior by restructuring dl_bw_manage() a bit, so
that overflow conditions (not enough bandwidth left) are properly
checked. Also account for dl_server bandwidth, i.e. discount such
bandwidth in the calculation since NORMAL tasks will be anyway moved
away from the CPU as a result of the hotplug operation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Juri Lelli <juri.lelli@redhat.com>
[ Upstream commit 53916d5fd3c0b658de3463439dd2b7ce765072cb ]
Currently we check for bandwidth overflow potentially due to hotplug
operations at the end of sched_cpu_deactivate(), after the cpu going
offline has already been removed from scheduling, active_mask, etc.
This can create issues for DEADLINE tasks, as there is a substantial
race window between the start of sched_cpu_deactivate() and the moment
we possibly decide to roll-back the operation if dl_bw_deactivate()
returns failure in cpuset_cpu_inactive(). An example is a throttled
task that sees its replenishment timer firing while the cpu it was
previously running on is considered offline, but before
dl_bw_deactivate() had a chance to say no and roll-back happened.
Fix this by directly calling dl_bw_deactivate() first thing in
sched_cpu_deactivate() and do the required calculation in the former
function considering the cpu passed as an argument as offline already.
By doing so we also simplify sched_cpu_deactivate(), as there is no need
anymore for any kind of roll-back if we fail early.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Carlos Llamas <cmllamas@google.com>
[ Upstream commit e638072e61726cae363d48812815197a2a0e097f ]
Lockdep has a set of configs used to determine the size of the static
arrays that it uses. However, the upper limit that was initially setup
for these configs is too high (30 bit shift). This equates to several
GiB of static memory for individual symbols. Using such high values
leads to linker errors:
$ make defconfig
$ ./scripts/config -e PROVE_LOCKING --set-val LOCKDEP_BITS 30
$ make olddefconfig all
[...]
ld: kernel image bigger than KERNEL_IMAGE_SIZE
ld: section .bss VMA wraps around address space
Adjust the upper limits to the maximum values that avoid these issues.
The need for anything more, likely points to a problem elsewhere. Note
that LOCKDEP_CHAINS_BITS was intentionally left out as its upper limit
had a different symptom and has already been fixed [1].

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yazen Ghannam <yazen.ghannam@amd.com>
[ Upstream commit bee9e840609cc67d0a7d82f22a2130fb7a0a766d ]
The code implicitly operates on AMD-based systems by matching on PCI
IDs. However, the use of these IDs is going away.
Add an explicit CPU vendor check instead of relying on PCI IDs.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dongwon Kim <dongwon.kim@intel.com>
[ Upstream commit d3c55b8ab6fe5fa2e7ab02efd36d09c39ee5022f ]
Having a fence linked to a virtio_gpu_framebuffer in the plane update
sequence would cause conflict when several planes referencing the same
framebuffer (e.g. Xorg screen covering multi-displays configured for an
extended mode) and those planes are updated concurrently. So it is needed
to allocate a fence for every plane state instead of the framebuffer.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
[ Upstream commit 22e5c7ae12145af13785e3ff138395d5b1a22116 ]
Panels using a PWM-controlled backlight source do not have a standard
way to communicate their valid PWM ranges.
On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an
older device can be retrofitted with newer panels.
Add a quirk infrastructure with which the minimum valid backlight value
can be maintained as part of the kernel.

------------------
From: Thomas Weißschuh <linux@weissschuh.net>
[ Upstream commit c2753b2471c65955de18cbc58530641447e5bfe9 ]
Not all platforms provide the full range of PWM backlight capabilities
supported by the hardware through ATIF.
Use the generic drm panel minimum backlight quirk infrastructure to
override the capabilities where necessary.
Testing the backlight quirk together with the "panel_power_savings"
sysfs file has not shown any negative impact.
One quirk seems to be that 0% at panel_power_savings=0 seems to be
slightly darker than at panel_power_savings=4.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
[ Upstream commit 916ecc0db336768d80e14ef28a8c64a775274f95 ]
The value of "min_input_signal" returned from ATIF on a Framework AMD 13
is "12". This leads to a fairly bright minimum display backlight.
Add a quirk to override that the minimum backlight PWM to "0" which
leads to a much lower minimum brightness, which is still visible.
Tested on a Framework AMD 13 BIOS 3.05 with the matte panel.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhi Wang <zhiw@nvidia.com>
[ Upstream commit 8d9beb4aebc02c4bd09e1d39c9c5f1c68c786dbc ]
A GSP event message consists three parts: message header, RPC header,
message body. GSP calculates the number of pages to write from the
total size of a GSP message. This behavior can be observed from the
movement of the write pointer.
However, nvkm takes only the size of RPC header and message body as
the message size when advancing the read pointer. When handling a
two-page GSP message in the non rollback case, It wrongly takes the
message body of the previous message as the message header of the next
message. As the "message length" tends to be zero, in the calculation of
size needs to be copied (0 - size of (message header)), the size needs to
be copied will be "0xffffffxx". It also triggers a kernel panic due to a
NULL pointer error.

Also, nvkm wrongly advances the read pointer when handling a two-page GSP
message in the rollback case. In the rollback case, the GSP message will
be copied in two rounds. When handling a two-page GSP message, nvkm first
copies amount of (GSP_PAGE_SIZE - header) data into the buffer, then
advances the read pointer by the result of DIV_ROUND_UP(size,
GSP_PAGE_SIZE). Thus, the read pointer is advanced by 1.
Next, nvkm copies the amount of (total size - (GSP_PAGE_SIZE -
header)) data into the buffer. The left amount of the data will be always
larger than one page since the message header is not taken into account
in the first copy. Thus, the read pointer is advanced by DIV_ROUND_UP(
size(larger than one page), GSP_PAGE_SIZE) = 2.
In the end, the read pointer is wrongly advanced by 3 when handling a
two-page GSP message in the rollback case.
Fix the problems by taking the total size of the message into account
when advancing the read pointer and calculate the read pointer in the end
of the all copies for the rollback case.
BTW: the two-page GSP message can be observed in the msgq when vGPU is
enabled.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhi Wang <zhiw@nvidia.com>
[ Upstream commit 01ed662bdd6fce4f59c1804b334610d710d79fa0 ]
r535_gsp_cmdq_push() waits for the available page in the GSP cmdq
buffer when handling a large RPC request. When it sees at least one
available page in the cmdq, it quits the waiting with the amount of
free buffer pages in the queue.
Unfortunately, it always takes the [write pointer, buf_size) as
available buffer pages before rolling back and wrongly calculates the
size of the data should be copied. Thus, it can overwrite the RPC
request that GSP is currently reading, which causes GSP hang due
to corrupted RPC request:

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit d3314efd6ebf335a3682b1d6b1b81cdab3d8254a ]
If the connector->modes list is empty, then list_first_entry() returns a
bogus entry. Change that to use list_first_entry_or_null().

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit a8403be6eea91e4f5d8ad5dbc463dd08339eaece ]
The set_connector_edid() function returns a bogus 0, performing the
check on the connector->funcs->fill_modes() result internally. Make the
function pass the fill_modes()'s return value to the caller and move
corresponding checks to the caller site.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ausef Yousof <Ausef.Yousof@amd.com>
[ Upstream commit 70fec46519fca859aa209f5f02e7e0a0123aca4a ]
[WHY]
Soft hang/lag observed during 10bit playback + moving cursor, corruption
observed in other tickets for same reason, also failing MPO.
1. Currently, we are always running
calculate_lowest_supported_state_for_temp_read which is only
necessary on dGPU
2. Fast validate path does not apply DET buffer allocation policy
3. Prefetch UrgBFactor chroma parameter not populated in prefetch
calculation
[HOW]
1. Add a check to see if we are on APU, if so, skip the code
2. Add det buffer alloc policy checks to fast validate path
3. Populate UrgentBurstChroma param in call to calculate
UrgBChroma prefetch values
-revision commits: small formatting/brackets/null check addition + remove test change + dGPU code

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ausef Yousof <Ausef.Yousof@amd.com>
[ Upstream commit 24909d9ec7c3afa8da2f3c9afa312e7a4a61f250 ]
[WHY]
Right now in dml2 mode validation we are calculating UBF parameters for
prefetch calculation for single and dual DPP scenarios. Data structure
to store such values are just 1D arrays, the single DPP values are
overwritten by the dualDPP values, and we end up using dualDPP for
prefetch calculations twice (once in place of singleDPP support check
and again for dual).
This naturally leads to many problems, one of which validating a mode in
"singleDPP" (when we used dual DPP parameters) and sending the singleDPP
parameters to mode programming, if we cannot support then we observe the
corruption as described in the ticket.
[HOW]
UBF values need to have 2d arrays to store values specific to single and
dual DPP states to avoid single DPP values being overwritten. Other
parameters are recorded on a per state basis such as prefetch UBF values
but they are in the same loop used for calculation and at that point its
fine to overwrite them, its not the case for plain UBF values.

From: Kuan-Wei Chiu <visitorckw@gmail.com>
[ Upstream commit 3d6f83df8ff2d5de84b50377e4f0d45e25311c7a ]
Shifting 1 << 31 on a 32-bit int causes signed integer overflow, which
leads to undefined behavior. To prevent this, cast 1 to u32 before
performing the shift, ensuring well-defined behavior.
This change explicitly avoids any potential overflow by ensuring that
the shift occurs on an unsigned 32-bit integer.

On chipsets such as QCS615, there is no 3dmux present. In such
a case, a layer exceeding the max_mixer_width cannot be split,
hence cannot be supported.
Filter out the modes which exceed the max_mixer_width when there
is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check()
to return failure for such modes.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit df7c8e3dde37a9d81c0613285b43600f3cc70f34 ]
The connector->eld is accessed by the .get_eld() callback. This access
can collide with the drm_edid_to_eld() updating the data at the same
time. Add drm_connector.eld_mutex to protect the data from concurrenct
access. Individual drivers are not updated (to reduce possible issues
while applying the patch), maintainers are to find a best suitable way
to lock that mutex while accessing the ELD data.

[ Upstream commit 81a9a93b169a273ccc4a9a1ee56f17e9981d3f98 ]
Reading access to connector->eld can happen at the same time the
drm_edid_to_eld() updates the data. Take the newly added eld_mutex in
order to protect connector->eld from concurrent access.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fangzhi Zuo <Jerry.Zuo@amd.com>
[ Upstream commit e56ad45e991128bf4db160b75a1d9f647a341d8f ]
Source --> DP2.1 MST hub --> DP1.4/2.1 monitor
When change from DP1.4 to DP2.1 from monitor manual, modes higher than
4k120 are all cutoff by mode validation. Switch back to DP1.4 gets all
the modes up to 4k240 available to be enabled by dsc passthrough.
[why]
Compared to DP1.4 link from hub to monitor, DP2.1 link has larger
full_pbn value that causes overflow in the process of doing conversion
from pbn to kbps.
[how]
Change the data type accordingly to fit into the data limit during
conversion calculation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Philip Yang <Philip.Yang@amd.com>
[ Upstream commit 34db5a32617d102e8042151bb87590e43c97132e ]
For CPX mode, each KFD node has interrupt worker to process ih_fifo to
send events to user space. Currently all interrupt workers of same adev
queue to same CPU, all workers execution are actually serialized and
this cause KFD ih_fifo overflow when CPU usage is high.
Use per-GPU unbounded highpri queue with number of workers equals to
number of partitions, let queue_work select the next CPU round robin
among the local CPUs of same NUMA.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hermes Wu <hermes.wu@ite.com.tw>
[ Upstream commit 8c01b0bae2f9e58f2fee0e811cb90d8331986554 ]
When starting HDCP authentication, HDCP encryption should be enabled
when R0'is checked.
Change encryption enables time at R0' ready.
The hardware HDCP engine trigger is changed and the repeater KSV fails
will restart HDCP.

From: Hermes Wu <hermes.wu@ite.com.tw>
[ Upstream commit 9f9eef9ec1a2b57d95a86fe81df758e8253a7766 ]
HDCP must disabled encryption and restart authentication after
waiting KSV for 5s.
The original method uses a counter in a waitting loop that may
wait much longer than it is supposed to.
Use time_after() for KSV wait timeout.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit e4479aecf6581af81bc0908575447878d2a07e01 ]
Commit 24909d9ec7c3 ("drm/amd/display: Overwriting dualDPP UBF values
before usage") added a new warning in dml2/display_mode_core.c when
building allmodconfig with clang:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6268:13: error: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than]
6268 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib)
| ^
Commit be4e3509314a ("drm/amd/display: DML21 Reintegration For Various
Fixes") introduced one in dml2_core/dml2_core_dcn4_calcs.c with the same
configuration:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: error: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than]
7236 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params)
| ^
In the case of the first warning, the stack usage was already at the
limit at the parent change, so the offending change was rather
innocuous. In the case of the second warning, there was a rather
dramatic increase in stack usage compared to the parent:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than]
7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params)
| ^
This is an unfortunate interaction between an issue with stack slot
reuse in LLVM that gets exacerbated by sanitization (which gets enabled
with all{mod,yes}config) and function calls using a much higher number
of parameters than is typical in the kernel, necessitating passing most
of these values on the stack.
While it is possible that there should be source code changes to address
these warnings, this code is difficult to modify for various reasons, as
has been noted in other changes that have occurred for similar reasons,
such as commit 6740ec97bcdb ("drm/amd/display: Increase frame warning
limit with KASAN or KCSAN in dml2").
Increase the frame larger than limit when compile testing with clang and
the sanitizers enabled to avoid this breakage in all{mod,yes}config, as
they are commonly used and valuable testing targets. While it is not the
best to hide this issue, it is not really relevant when compile testing,
as the sanitizers are commonly stressful on optimizations and they are
only truly useful at runtime, which COMPILE_TEST states will not occur
with the current build.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeongjun Park <aha310510@gmail.com>
[ Upstream commit 6e31b759b076eebb4184117234f0c4eb9e4bc460 ]
In the loop of __rb_map_vma(), the 's' variable is calculated from the
same logic that nr_pages is and they both come from nr_subbufs. But the
relationship is not obvious and there's a WARN_ON_ONCE() around the 's'
variable to make sure it never becomes equal to nr_subbufs within the
loop. If that happens, then the code is buggy and needs to be fixed.
The 'page' variable is calculated from cpu_buffer->subbuf_ids[s] which is
an array of 'nr_subbufs' entries. If the code becomes buggy and 's'
becomes equal to or greater than 'nr_subbufs' then this will be an out of
bounds hit before the WARN_ON() is triggered and the code exiting safely.
Make the 'page' initialization consistent with the code logic and assign
it after the out of bounds check.

From: Karol Przybylski <karprzy7@gmail.com>
[ Upstream commit eb8c0534713865d190856f10bfc97cf0b88475b1 ]
Selfgen stats are placed in a buffer using print_array_to_buf_index() function.
Array length parameter passed to the function is too big, resulting in possible
out-of bound memory error.
Decreasing buffer size by one fixes faulty upper bound of passed array.
Discovered in coverity scan, CID 1600742 and CID 1600758

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kalle Valo <quic_kvalo@quicinc.com>
[ Upstream commit ad969bc9ee73fa9eda6223be2a7c0c6caf937d71 ]
Dan reported that in some cases the ret variable could be uninitialized. Fix
that by removing the out label entirely and returning zero explicitly on
succesful cases.
Also remove the unnecessary else branches to follow more the style used in
ath12k and now it's easier to see the error handling.
No functional changes.

From: Chih-Kang Chang <gary.chang@realtek.com>
[ Upstream commit 7b98caea39676561f22db58752551161bb36462b ]
In the original flow, the crystal_cap might be calculated as a negative
value and set as an overflow value. Therefore, we added a check to limit
the calculated crystal_cap value. Additionally, we shrank the crystal_cap
adjustment according to specific CFO.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stas Sergeev <stsp2@yandex.ru>
[ Upstream commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3 ]
Currently tun checks the group permission even if the user have matched.
Besides going against the usual permission semantic, this has a
very interesting implication: if the tun group is not among the
supplementary groups of the tun user, then effectively no one can
access the tun device. CAP_SYS_ADMIN still can, but its the same as
not setting the tun ownership.
This patch relaxes the group checking so that either the user match
or the group match is enough. This avoids the situation when no one
can access the device even though the ownership is properly set.
Also I simplified the logic by removing the redundant inversions:
tun_not_capable() --> !tun_capable()

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
[ Upstream commit 3df7546fc03b8f004eee0b9e3256369f7d096685 ]
syzbot is reporting too large allocation warning at tomoyo_write_control(),
for one can write a very very long line without new line character. To fix
this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE,
for practically a valid line should be always shorter than 32KB where the
"too small to fail" memory-allocation rule applies.
One might try to write a valid line that is longer than 32KB, but such
request will likely fail with -ENOMEM. Therefore, I feel that separately
returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant.
There is no need to distinguish over-32KB and over-KMALLOC_MAX_SIZE.

------------------
From: Ping-Ke Shih <pkshih@realtek.com>
[ Upstream commit 0daa521a1c8c29ffbefe6530f0d276e74e2749d0 ]
The layout struct of efuse should not do address alignment by compiler.
Otherwise it leads unexpected layout and size for certain arch suc as arm.
In x86-64, the results are identical before and after this patch.
Also adjust bit-field to prevent over adjacent byte to avoid warning:

Like all other non-ancient Qualcomm clock drivers, QCOM_GDSC is
required, as the GCC driver defines and instantiates a bunch of GDSCs.
Add the missing dependency.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
[ Upstream commit 1ce840c7a659aa53a31ef49f0271b4fd0dc10296 ]
Currently, when firmware failure occurs during matcher disconnect flow,
the error flow of the function reconnects the matcher back and returns
an error, which continues running the calling function and eventually
frees the matcher that is being disconnected.
This leads to a case where we have a freed matcher on the matchers list,
which in turn leads to use-after-free and eventual crash.
This patch fixes that by not trying to reconnect the matcher back when
some FW command fails during disconnect.
Note that we're dealing here with FW error. We can't overcome this
problem. This might lead to bad steering state (e.g. wrong connection
between matchers), and will also lead to resource leakage, as it is
the case with any other error handling during resource destruction.
However, the goal here is to allow the driver to continue and not crash
the machine with use-after-free error.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
[ Upstream commit 61fb92701b8ac9174857c417cfa988adc24e32c2 ]
Rule counter in matcher's struct is used in two places:
1. As heuristics to decide when the number of rules have crossed a
certain percentage threshold and the matcher should be resized.
We don't mind here if the number will be off by 1-2 due to concurrency.
2. When destroying matcher, the counter value is checked and the
user is warned if it is not 0. Here we lock all the queues, so the
counter will be correct.
We don't need to always have *exact* number, but we do need this
number to not be corrupted, which is what is happening when the
counter isn't atomic, due to update by different threads.

From: Vadim Fedorenko <vadfed@meta.com>
[ Upstream commit e61e6c415ba9ff2b32bb6780ce1b17d1d76238f1 ]
The overflow_work is using system wq to do overflow checks and updates
for PHC device timecounter, which might be overhelmed by other tasks.
But there is dedicated kthread in PTP subsystem designed for such
things. This patch changes the work queue to proper align with PTP
subsystem and to avoid overloading system work queue.
The adjfine() function acts the same way as overflow check worker,
we can postpone ptp aux worker till the next overflow period after
adjfine() was called.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andre Przywara <andre.przywara@arm.com>
[ Upstream commit b246bd32a34c1b0d80670e60e4e4102be6366191 ]
As Chris and Vasily reported, the attempt to support multiple AXP PMICs
in one system [1] breaks some of the battery and charging functionality
on devices with AXP PMICs. The reason is that the drivers now fail to get
the correct IIO channel for the ADC component, as the current code seems
to rely on the zero-based enumeration of the regulator devices.
A fix is possible, but not trivial, as it requires some rework in the AXP
MFD driver, which cannot be fully reviewed or tested in time for the
6.13 release.
So revert this patch for now, to avoid regressions on battery powered
devices. This patch was really only necessary for devices with two
PMICs, support for which is not mainline yet anyway, so we don't lose
any functionality.
This reverts commit e37ec32188701efa01455b9be42a392adab06ce4.

From: Stefan Dösinger <stefan@codeweavers.com>
[ Upstream commit 082d9e263af8de68f0c34f67b251818205160f6e ]
Somewhen between 6.10 and 6.11 the driver started to crash on my
MacBookPro14,3. The property doesn't exist and 'tmp' remains
uninitialized, so we pass a random pointer to devm_kstrdup().
The crash I am getting looks like this:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miri Korenblit <miriam.rachel.korenblit@intel.com>
[ Upstream commit 80e96206a3ef348fbd658d98f2f43149c36df8bc ]
A caller of iwl_acpi_get_dsm_object must free the returned object.
iwl_acpi_get_dsm_integer returns immediately without freeing
it if the expected size is more than 8 bytes. Fix that.
Note that with the current code this will never happen, since the caller
of iwl_acpi_get_dsm_integer already checks that the expected size if
either 1 or 4 bytes, so it can't exceed 8 bytes.
While at it, print the DSM value instead of the return value, as this
was the intention in the first place.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Randolph Ha <rha051117@gmail.com>
[ Upstream commit bfd74cd1fbc026f04446e67d6915c7e199c2bffd ]
When a 400KHz freq is used on this model of ELAN touchpad in Linux,
excessive smoothing (similar to when the touchpad's firmware detects
a noisy signal) is sometimes applied. As some devices' (e.g, Lenovo
V15 G4) ACPI tables specify a 400KHz frequency for this device and
some I2C busses (e.g, Designware I2C) default to a 400KHz freq,
force the speed to 100KHz as a workaround.
For future investigation: This problem may be related to the default
HCNT/LCNT values given by some busses' drivers, because they are not
specified in the aforementioned devices' ACPI tables, and because
the device works without issues on Windows at what is expected to be
a 400KHz frequency. The root cause of the issue is not known.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Borislav Petkov <bp@alien8.de>
[ Upstream commit 5c0e00a391dd0099fe95991bb2f962848d851916 ]
The GHES driver overrides the panic= setting by force-rebooting the
system after a fatal hw error has been reported. The intent being that
such an error would be reported earlier.
However, this is not optimal when a hard-to-debug issue requires long
time to reproduce and when that happens, the box will get rebooted after
30 seconds and thus destroy the whole hw context of when the error
happened.
So rip out the default GHES panic timeout and honor the global one.
In the panic disabled (panic=0) case, the error will still be logged to
dmesg for later inspection and if panic after a hw error is really
required, then that can be controlled the usual way - use panic= on the
cmdline or set it in the kernel .config's CONFIG_PANIC_TIMEOUT.

From: Andrew Halaney <ajhalaney@gmail.com>
[ Upstream commit 45e7d389bf2e52dfc893779c611dd5cff461b590 ]
A new machine has a Archer AX3000 / TX55e in it,
and out the box reported issues resetting hci0. It looks like
this is a MT7922 from the lspci output, so treat it as a MediaTek
device and use the proper callbacks. With that in place an xbox
controller can be used without issue as seen below:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej S. Szmigiero <mail@maciej.szmigiero.name>
[ Upstream commit 0b6f6593aa8c3a05f155c12fd0e7ad33a5149c31 ]
Currently, the driver is seriously broken with respect to the
hibernation (S4): after image restore the device is back into
IPC_MEM_EXEC_STAGE_BOOT (which AFAIK means bootloader stage) and needs
full re-launch of the rest of its firmware, but the driver restore
handler treats the device as merely sleeping and just sends it a
wake-up command.
This wake-up command times out but device nodes (/dev/wwan*) remain
accessible.
However attempting to use them causes the bootloader to crash and
enter IPC_MEM_EXEC_STAGE_CD_READY stage (which apparently means "a crash
dump is ready").
It seems that the device cannot be re-initialized from this crashed
stage without toggling some reset pin (on my test platform that's
apparently what the device _RST ACPI method does).
While it would theoretically be possible to rewrite the driver to tear
down the whole MUX / IPC layers on hibernation (so the bootloader does
not crash from improper access) and then re-launch the device on
restore this would require significant refactoring of the driver
(believe me, I've tried), since there are quite a few assumptions
hard-coded in the driver about the device never being partially
de-initialized (like channels other than devlink cannot be closed,
for example).
Probably this would also need some programming guide for this hardware.
Considering that the driver seems orphaned [1] and other people are
hitting this issue too [2] fix it by simply unbinding the PCI driver
before hibernation and re-binding it after restore, much like
USB_QUIRK_RESET_RESUME does for USB devices that exhibit a similar
problem.
Tested on XMM7360 in HP EliteBook 855 G7 both with s2idle (which uses
the existing suspend / resume handlers) and S4 (which uses the new code).

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luke D. Jones <luke@ljones.dev>
[ Upstream commit 53078a736fbc60e5d3a1e14f4cd4214003815026 ]
The new ASUS ProArt 16" laptop series come with their keyboards stuck in
an Out-Of-Box-Experience mode. While in this mode most functions will
not work such as LED control or Fn key combos. The correct init sequence
is now done to disable this OOBE.
This patch addresses only the ProArt series so far and it is unknown if
there may be others, in which case a new quirk may be required.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuanjie Yang <quic_yuanjiey@quicinc.com>
[ Upstream commit 20a0c37e44063997391430c4ae09973e9cbc3911 ]
Qualcomm regulator supports two power supply modes: HPM and LPM.
Currently, the sdhci-msm.c driver does not set the load to adjust
the current for eMMC and SD. If the regulator dont't set correct
load in LPM state, it will lead to the inability to properly
initialize eMMC and SD.
Set the correct regulator current for eMMC and SD to ensure that the
device can work normally even when the regulator is in LPM.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shinas Rasheed <srasheed@marvell.com>
[ Upstream commit f84039939512e6d88b0f2f353695530f123be789 ]
Update tx/rx stats locally, so that ndo_get_stats64()
can use that and not rely on per queue resources to obtain statistics.
The latter used to cause race conditions when the device stopped.

------------------
From: Dan Carpenter <dan.carpenter@linaro.org>
[ Upstream commit 5fe71fda89745fc3cd95f70d06e9162b595c3702 ]
On a 32bit system the "keylen + sizeof(struct tipc_aead_key)" math could
have an integer wrapping issue. It doesn't matter because the "keylen"
is checked on the next line, but just to make life easier for static
analysis tools, let's re-order these conditions and avoid the integer
overflow.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roger Quadros <rogerq@kernel.org>
[ Upstream commit 681eb2beb3efe21e630bcc4881595e3b42dd7948 ]
We are missing netif_napi_del() and am65_cpsw_nuss_free_tx/rx_chns()
in error path when am65_cpsw_nuss_init_tx/rx_chns() is used anywhere
other than at probe(). i.e. am65_cpsw_nuss_update_tx_rx_chns and
am65_cpsw_nuss_resume()
As reported, in am65_cpsw_nuss_update_tx_rx_chns(),
if am65_cpsw_nuss_init_tx_chns() partially fails then
devm_add_action(dev, am65_cpsw_nuss_free_tx_chns,..) is added
but the cleanup via am65_cpsw_nuss_free_tx_chns() will not run.
Same issue exists for am65_cpsw_nuss_init_tx/rx_chns() failures
in am65_cpsw_nuss_resume() as well.
This would otherwise require more instances of devm_add/remove_action
and is clearly more of a distraction than any benefit.
So, drop devm_add/remove_action for am65_cpsw_nuss_free_tx/rx_chns()
and call am65_cpsw_nuss_free_tx/rx_chns() and netif_napi_del()
where required.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bard Liao <yung-chuan.liao@linux.intel.com>
[ Upstream commit 569922b82ca660f8b24e705f6cf674e6b1f99cc7 ]
Each cpu DAI should associate with a widget. However, the topology might
not create the right number of DAI widgets for aggregated amps. And it
will cause NULL pointer deference.
Check that the DAI widget associated with the CPU DAI is valid to prevent
NULL pointer deference due to missing DAI widgets in topologies with
aggregated amps.

------------------
From: Kumar Kartikeya Dwivedi <memxor@gmail.com>
[ Upstream commit cbd8730aea8d79cda6b0f3c18b406dfdef0c1b80 ]
The verifier log when leaking resources on BPF_EXIT may be a bit
confusing, as it's a problem only when finally existing from the main
prog, not from any of the subprogs. Hence, update the verifier error
string and the corresponding selftests matching on it.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Woodhouse <dwmw@amazon.co.uk>
[ Upstream commit 4b5bc2ec9a239bce261ffeafdd63571134102323 ]
Now that the following fix:
d0ceea662d45 ("x86/mm: Add _PAGE_NOPTISHADOW bit to avoid updating userspace page tables")
stops kernel_ident_mapping_init() from scribbling over the end of a
4KiB PGD by assuming the following 4KiB will be a userspace PGD,
there's no good reason for the kexec PGD to be part of a single
8KiB allocation with the control_code_page.
( It's not clear that that was the reason for x86_64 kexec doing it that
way in the first place either; there were no comments to that effect and
it seems to have been the case even before PTI came along. It looks like
it was just a happy accident which prevented memory corruption on kexec. )
Either way, it definitely isn't needed now. Just allocate the PGD
separately on x86_64, like i386 already does.

In addition to changing the DMI match to examine the product name rather
than the SKU, this adds the quirk to inform the machine driver to not
bind in the cs42l43 microphone DAI link.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Acayan <mailingradian@gmail.com>
[ Upstream commit 42314738906380cbd3b6e9caf3ad34e1b2d66035 ]
Add the compatible for the separate IOMMU on SDM670 for the Adreno GPU.
This IOMMU has the compatible strings:
"qcom,sdm670-smmu-v2", "qcom,adreno-smmu", "qcom,smmu-v2"
While the SMMU 500 doesn't need an entry for this specific SoC, the
SMMU v2 compatible should have its own entry, as the fallback entry in
arm-smmu.c handles "qcom,smmu-v2" without per-process page table support
unless there is an entry here. This entry can't be the
"qcom,adreno-smmu" compatible because dedicated GPU IOMMUs can also be
SMMU 500 with different handling.

------------------
From: Robin Murphy <robin.murphy@arm.com>
[ Upstream commit fcbd621567420b3a2f21f49bbc056de8b273c625 ]
kmemleak noticed that the iopf queue allocated deep down within
arm_smmu_init_structures() can be leaked by a subsequent error return
from arm_smmu_device_probe(). Furthermore, after arm_smmu_device_reset()
we will also leave the SMMU enabled with an empty Stream Table, silently
blocking all DMA. This proves rather annoying for debugging said probe
failure, so let's handle it a bit better by putting the SMMU back into
(more or less) the same state as if it hadn't probed at all.

------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit cd2fd6eab480dfc247b737cf7a3d6b009c4d0f1c ]
Not all devices have an ACPI companion fwnode, so adev might be NULL. This
can e.g. (theoretically) happen when a user manually binds one of
the int3472 drivers to another i2c/platform device through sysfs.
Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().

------------------
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
[ Upstream commit 301c26a018acb94dd537a4418cefa0f654500c6f ]
commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port"
log severity") ignores -EINVAL error message on common soc_pcm_ret().
It is used from many functions, ignoring -EINVAL is over-kill.
The reason why -EINVAL was ignored was it really should only be used
upon invalid parameters coming from userspace and in that case we don't
want to log an error since we do not want to give userspace a way to do
a denial-of-service attack on the syslog / diskspace.
So don't use soc_pcm_ret() on .prepare callback is better idea.

There is a WARN_ON_ONCE to catch an unlikely situation when
domain_remove_dev_pasid can't find the `pasid`. In case it nevertheless
happens we must avoid using a NULL pointer.

From: Armin Wolf <W_Armin@gmx.de>
[ Upstream commit f6bfa25c6665f8721421ea94fe506cc22f1d4b43 ]
On the Acer Swift SFG14-41, the events 8 - 1 and 8 - 0 are printed on
AC connect/disconnect. Ignore those events to avoid spamming the
kernel log with error messages.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Anderson <sean.anderson@linux.dev>
commit b06f388994500297bb91be60ffaf6825ecfd2afe upstream.
lockdep detects the following circular locking dependency:
CPU 0 CPU 1
========================== ============================
cdns_uart_isr() printk()
uart_port_lock(port) console_lock()
cdns_uart_console_write()
if (!port->sysrq)
uart_port_lock(port)
uart_handle_break()
port->sysrq = ...
uart_handle_sysrq_char()
printk()
console_lock()
The fixed commit attempts to avoid this situation by only taking the
port lock in cdns_uart_console_write if port->sysrq unset. However, if
(as shown above) cdns_uart_console_write runs before port->sysrq is set,
then it will try to take the port lock anyway. This may result in a
deadlock.
Fix this by splitting sysrq handling into two parts. We use the prepare
helper under the port lock and defer handling until we release the lock.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Günther Noack <gnoack@google.com>
commit 2f83e38a095f8bf7c6029883d894668b03b9bd93 upstream.
With this, processes without CAP_SYS_ADMIN are able to use TIOCLINUX with
subcode TIOCL_SETSEL, in the selection modes TIOCL_SETPOINTER,
TIOCL_SELCLEAR and TIOCL_SELMOUSEREPORT.
TIOCL_SETSEL was previously changed to require CAP_SYS_ADMIN, as this IOCTL
let callers change the selection buffer and could be used to simulate
keypresses. These three TIOCL_SETSEL selection modes, however, are safe to
use, as they do not modify the selection buffer.
This fixes a mouse support regression that affected Emacs (invisible mouse
cursor).

commit 478b00a623d6c8ae23a1be7bcc96cb5497045cef upstream.
dell_uart_bl_pdev_probe() calls get_serdev_controller() with the
serial_ctrl_uid parameter set to NULL.
In case of errors this NULL parameter then gets passed to pr_err()
as argument matching a "%s" conversion specification. This leads to
compiler warnings when building with "make W=1".
Check serial_ctrl_uid before passing it to pr_err() to avoid these.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: K Prateek Nayak <kprateek.nayak@amd.com>
[ Upstream commit 3429dd57f0deb1a602c2624a1dd7c4c11b6c4734 ]
set_delayed() adjusts cfs_rq->h_nr_runnable for the hierarchy when an
entity is delayed irrespective of whether the entity corresponds to a
task or a cfs_rq.
Consider the following scenario:
root
/ \
A B (*) delayed since B is no longer eligible on root
| |
Task0 Task1 <--- dequeue_task_fair() - task blocks
When Task1 blocks (dequeue_entity() for task's se returns true),
dequeue_entities() will continue adjusting cfs_rq->h_nr_* for the
hierarchy of Task1. However, when the sched_entity corresponding to
cfs_rq B is delayed, set_delayed() will adjust the h_nr_runnable for the
hierarchy too leading to both dequeue_entity() and set_delayed()
decrementing h_nr_runnable for the dequeue of the same task.
A SCHED_WARN_ON() to inspect h_nr_runnable post its update in
dequeue_entities() like below:
cfs_rq->h_nr_runnable -= h_nr_runnable;
SCHED_WARN_ON(((int) cfs_rq->h_nr_runnable) < 0);
is consistently tripped when running wakeup intensive workloads like
hackbench in a cgroup.
This error is self correcting since cfs_rq are per-cpu and cannot
migrate. The entitiy is either picked for full dequeue or is requeued
when a task wakes up below it. Both those paths call clear_delayed()
which again increments h_nr_runnable of the hierarchy without
considering if the entity corresponds to a task or not.
h_nr_runnable will eventually reflect the correct value however in the
interim, the incorrect values can still influence PELT calculation which
uses se->runnable_weight or cfs_rq->h_nr_runnable.
Since only delayed tasks take the early return path in
dequeue_entities() and enqueue_task_fair(), adjust the
h_nr_runnable in {set,clear}_delayed() only when a task is delayed as
this path skips the h_nr_* update loops and returns early.
For entities corresponding to cfs_rq, the h_nr_* update loop in the
caller will do the right thing.

------------------
From: Daniel Wagner <wagi@kernel.org>
[ Upstream commit 294b2b7516fd06a8dd82e4a6118f318ec521e706 ]
When the set feature attempts fails with any NVME status code set in
nvme_set_queue_count, the function still report success. Though the
numbers of queues set to 0. This is done to support controllers in
degraded state (the admin queue is still up and running but no IO
queues).
Though there is an exception. When nvme_set_features reports an host
path error, nvme_set_queue_count should propagate this error as the
connectivity is lost, which means also the admin queue is not working
anymore.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hverkuil@xs4all.nl>
[ Upstream commit 6daaae5ff7f3b23a2dacc9c387ff3d4f95b67cad ]
If the hotplug detect of a display is low for longer than one second
(configurable through drm_dp_cec_unregister_delay), then the CEC adapter
is unregistered since we assume the display was disconnected. If the
HPD went low for less than one second, then we check if the properties
of the CEC adapter have changed, since that indicates that we actually
switch to new hardware and we have to unregister the old CEC device and
register a new one.
Unfortunately, the test for changed properties was written poorly, and
after a new CEC capability was added to the CEC core code the test always
returned true (i.e. the properties had changed).
As a result the CEC device was unregistered and re-registered for every
HPD toggle. If the CEC remote controller integration was also enabled
(CONFIG_MEDIA_CEC_RC was set), then the corresponding input device was
also unregistered and re-registered. As a result the input device in
/sys would keep incrementing its number, e.g.:
/sys/devices/pci0000:00/0000:00:08.1/0000:e7:00.0/rc/rc0/input20
Since short HPD toggles are common, the number could over time get into
the thousands.
While not a serious issue (i.e. nothing crashes), it is not intended
to work that way.
This patch changes the test so that it only checks for the single CEC
capability that can actually change, and it ignores any other
capabilities, so this is now safe as well if new caps are added in
the future.
With the changed test the bit under #ifndef CONFIG_MEDIA_CEC_RC can be
dropped as well, so that's a nice cleanup.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej Fijalkowski <maciej.fijalkowski@intel.com>
[ Upstream commit 743bbd93cf29f653fae0e1416a31f03231689911 ]
Introduce a new helper ice_put_rx_mbuf() that will go through gathered
frags from current frame and will call ice_put_rx_buf() on them. Current
logic that was supposed to simplify and optimize the driver where we go
through a batch of all buffers processed in current NAPI instance turned
out to be broken for jumbo frames and very heavy load that was coming
from both multi-thread iperf and nginx/wrk pair between server and
client. The delay introduced by approach that we are dropping is simply
too big and we need to take the decision regarding page
recycling/releasing as quick as we can.
While at it, address an error path of ice_add_xdp_frag() - we were
missing buffer putting from day 1 there.
As a nice side effect we get rid of annoying and repetitive three-liner:
xdp->data = NULL;
rx_ring->first_desc = ntc;
rx_ring->nr_frags = 0;
by embedding it within introduced routine.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej Fijalkowski <maciej.fijalkowski@intel.com>
[ Upstream commit 11c4aa074d547d825b19cd8d9f288254d89d805c ]
If we store the pgcnt on few fragments while being in the middle of
gathering the whole frame and we stumbled upon DD bit not being set, we
terminate the NAPI Rx processing loop and come back later on. Then on
next NAPI execution we work on previously stored pgcnt.
Imagine that second half of page was used actively by networking stack
and by the time we came back, stack is not busy with this page anymore
and decremented the refcnt. The page reuse algorithm in this case should
be good to reuse the page but given the old refcnt it will not do so and
attempt to release the page via page_frag_cache_drain() with
pagecnt_bias used as an arg. This in turn will result in negative refcnt
on struct page, which was initially observed by Xu Du.
Therefore, move the page count storage from ice_get_rx_buf() to a place
where we are sure that whole frame has been collected, but before
calling XDP program as it internally can also change the page count of
fragments belonging to xdp_buff.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej Fijalkowski <maciej.fijalkowski@intel.com>
[ Upstream commit 468a1952df78f65c5991b7ac885c8b5b7dd87bab ]
Idea behind having ice_rx_buf::act was to simplify and speed up the Rx
data path by walking through buffers that were representing cleaned HW
Rx descriptors. Since it caused us a major headache recently and we
rolled back to old approach that 'puts' Rx buffers right after running
XDP prog/creating skb, this is useless now and should be removed.
Get rid of ice_rx_buf::act and related logic. We still need to take care
of a corner case where XDP program releases a particular fragment.
Make ice_run_xdp() to return its result and use it within
ice_put_rx_mbuf().
Fixes: 2fba7dc5157b ("ice: Add support for XDP multi-buffer on Rx side")

From: Florian Fainelli <florian.fainelli@broadcom.com>
[ Upstream commit 46ded709232344b5750a852747a8881763c721ab ]
Some Wake-on-LAN modes such as WAKE_FILTER may only be supported by the MAC,
while others might be only supported by the PHY. Make sure that the .get_wol()
returns the union of both rather than only that of the PHY if the PHY supports
Wake-on-LAN.
When disabling Wake-on-LAN, make sure that this is done at both the PHY
and MAC level, rather than doing an early return from the PHY driver.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sankararaman Jayaraman <sankararaman.jayaraman@broadcom.com>
[ Upstream commit 3f1baa91a1fdf3de9dbad4bd615b35fab347874b ]
If XDP traffic runs on a CPU which is greater than or equal to
the number of the Tx queues of the NIC, then vmxnet3_xdp_get_tq()
always picks up queue 0 for transmission as it uses reciprocal scale
instead of simple modulo operation.
vmxnet3_xdp_xmit() and vmxnet3_xdp_xmit_frame() use the above
returned queue without any locking which can lead to race conditions
when multiple XDP xmits run in parallel on different CPU's.
This patch uses a simple module scheme when the current CPU equals or
exceeds the number of Tx queues on the NIC. It also adds locking in
vmxnet3_xdp_xmit() and vmxnet3_xdp_xmit_frame() functions.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lenny Szubowicz <lszubowi@redhat.com>
[ Upstream commit e0efe83ed325277bb70f9435d4d9fc70bebdcca8 ]
Disable PCIe AER on the tg3 device on system reboot on a limited
list of Dell PowerEdge systems. This prevents a fatal PCIe AER event
on the tg3 device during the ACPI _PTS (prepare to sleep) method for
S5 on those systems. The _PTS is invoked by acpi_enter_sleep_state_prep()
as part of the kernel's reboot sequence as a result of commit
38f34dba806a ("PM: ACPI: reboot: Reinstate S5 for reboot").
There was an earlier fix for this problem by commit 2ca1c94ce0b6
("tg3: Disable tg3 device on system reboot to avoid triggering AER").
But it was discovered that this earlier fix caused a reboot hang
when some Dell PowerEdge servers were booted via ipxe. To address
this reboot hang, the earlier fix was essentially reverted by commit
9fc3bc764334 ("tg3: power down device only on SYSTEM_POWER_OFF").
This re-exposed the tg3 PCIe AER on reboot problem.
This fix is not an ideal solution because the root cause of the AER
is in system firmware. Instead, it's a targeted work-around in the
tg3 driver.
Note also that the PCIe AER must be disabled on the tg3 device even
if the system is configured to use "firmware first" error handling.
V3:
- Fix sparse warning on improper comparison of pdev->current_state
- Adhere to netdev comment style

From: Yan Zhai <yan@cloudflare.com>
[ Upstream commit 235174b2bed88501fda689c113c55737f99332d8 ]
Commit 4094871db1d6 ("udp: only do GSO if # of segs > 1") avoided GSO
for small packets. But the kernel currently dismisses GSO requests only
after checking MTU/PMTU on gso_size. This means any packets, regardless
of their payload sizes, could be dropped when PMTU becomes smaller than
requested gso_size. We encountered this issue in production and it
caused a reliability problem that new QUIC connection cannot be
established before PMTU cache expired, while non GSO sockets still
worked fine at the same time.
Ideally, do not check any GSO related constraints when payload size is
smaller than requested gso_size, and return EMSGSIZE instead of EINVAL
on MTU/PMTU check failure to be more specific on the error cause.

From: Suraj Kandpal <suraj.kandpal@intel.com>
[ Upstream commit 448060463198924c0a485e7e1622fa8a9c03cf3e ]
When topology changes, before beginning a new HDCP authentication by
sending AKE_init message we need to first authenticate only the
repeater. Only after repeater authentication failure, it makes sense
to start a new HDCP authentication. Even though it made sense to not
enable HDCP directly from check_link and schedule it for later, repeater
authentication needs to be done immediately.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ankit Nautiyal <ankit.k.nautiyal@intel.com>
[ Upstream commit 4466302262b38f5e6c65325035b4036a42efc934 ]
Currently we support Adaptive sync operation mode with dynamic frame
rate, but instead the operation mode with fixed rate is set.
This was initially set correctly in the earlier version of changes but
later got changed, while defining a macro for the same.
Fixes: a5bd5991cb8a ("drm/i915/display: Compute AS SDP parameters")

[ Upstream commit 588c20079e17dae9e1f49ba42981a05de1c9136e ]
UMD's have interest in setting unused bits of the oa_ctrl register "out of
band" for certain experiments. To facilitate this, don't clobber previous
oa_ctrl unused bits, i.e. rmw the values rather than simply write them.

The migration support only needs to be initialized once, but it
was incorrectly called from the xe_gt_sriov_pf_init_hw(), which
is part of the reset flow and may be called multiple times.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakub Kicinski <kuba@kernel.org>
[ Upstream commit 244f8aa46fa9e2f4ea5fe0e04988b395d5e30fc7 ]
Commit ec6e57beaf8b ("ethtool: rss: don't report key if device
doesn't support it") intended to stop reporting key fields for
additional rss contexts if device has a global hashing key.
Later we added dump support and the filtering wasn't properly
added there. So we end up reporting the key fields in dumps
but not in dos:
# ./pyynl/cli.py --spec netlink/specs/ethtool.yaml --do rss-get \
--json '{"header": {"dev-index":2}, "context": 1 }'
{
"header": { ... },
"context": 1,
"indir": [0, 1, 2, 3, ...]]
}
# ./pyynl/cli.py --spec netlink/specs/ethtool.yaml --dump rss-get
[
... snip context 0 ...
{ "header": { ... },
"context": 1,
"indir": [0, 1, 2, 3, ...],
-> "input_xfrm": 255,
-> "hfunc": 1,
-> "hkey": "000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
}
]
Hide these fields correctly.
The drivers/net/hw/rss_ctx.py selftest catches this when run on
a device with single key, already:
# Check| At /root/./ksft-net-drv/drivers/net/hw/rss_ctx.py, line 381, in test_rss_context_dump:
# Check| ksft_ne(set(data.get('hkey', [1])), {0}, "key is all zero")
# Check failed {0} == {0} key is all zero
not ok 8 rss_ctx.test_rss_context_dump

From: Jakub Kicinski <kuba@kernel.org>
[ Upstream commit 2b91cc1214b165c25ac9b0885db89a0d3224028a ]
The info.flow_type is for RXFH commands, ntuple flow_type is inside
the flow spec. The check currently does nothing, as info.flow_type
is 0 (or even uninitialized by user space) for ETHTOOL_SRXCLSRLINS.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@redhat.com>
[ Upstream commit 4241a702e0d0c2ca9364cfac08dbf134264962de ]
The rxrpc_connection attend queue is never used because conn::attend_link
is never initialised and so is always NULL'd out and thus always appears to
be busy. This requires the following fix:
(1) Fix this the attend queue problem by initialising conn::attend_link.
And, consequently, two further fixes for things masked by the above bug:
(2) Fix rxrpc_input_conn_event() to handle being invoked with a NULL
sk_buff pointer - something that can now happen with the above change.
(3) Fix the RXRPC_SKB_MARK_SERVICE_CONN_SECURED message to carry a pointer
to the connection and a ref on it.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>
[ Upstream commit d6179f6c6204f9932aed3a7a2100b4a295dfed9d ]
The GPIO drivers with latch interrupt support (typically types starting
with PCAL) have interrupt status registers to determine which particular
inputs have caused an interrupt. Unfortunately there is no atomic
operation to read these registers and clear the interrupt. Clearing the
interrupt is done by reading the input registers.
The code was reading the interrupt status registers, and then reading
the input registers. If an input changed between these two events it was
lost.
The solution in this patch is to revert to the non-latch version of
code, i.e. remembering the previous input status, and looking for the
changes. This system results in no more I2C transfers, so is no slower.
The latch property of the device still means interrupts will still be
noticed if the input changes back to its initial state.

Firmware deinitialization performs MMIO accesses which are not
necessary if the device has already been removed. In some cases,
these accesses happen via readx_poll_timeout_atomic which ends up
timing out, resulting in a warning at hw_atl2_utils_fw.c:112:

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

From: Geert Uytterhoeven <geert+renesas@glider.be>
[ Upstream commit 5393f40a640b8c4f716bf87e7b0d4328bf1f22b2 ]
While the Aeroflex Gaisler GRGPIO driver has no build-time dependency on
gpiolib-of, it supports only DT-based configuration, and is used only on
DT systems. Hence add a dependency on OF, to prevent asking the user
about this driver when configuring a kernel without DT support.

From: Juergen Gross <jgross@suse.com>
[ Upstream commit 98a5cfd2320966f40fe049a9855f8787f0126825 ]
xen_hypercall_hvm(), which is used when running as a Xen PVH guest at
most only once during early boot, is clobbering %rbx. Depending on
whether the caller relies on %rbx to be preserved across the call or
not, this clobbering might result in an early crash of the system.
This can be avoided by using an already saved register instead of %rbx.

While analysing code for software and OF node for the corner case when
caller asks to read zero items in the supposed to be an array of values
I found that ACPI behaves differently to what OF does, i.e.
1. It returns -EINVAL when caller asks to read zero items from integer
array, while OF returns 0, if no other errors happened.
2. It returns -EINVAL when caller asks to read zero items from string
array, while OF returns -ENODATA, if no other errors happened.
Amend ACPI implementation to follow what OF does.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quang Le <quanglex97@gmail.com>
[ Upstream commit 647cef20e649c576dff271e018d5d15d998b629d ]
Expected behaviour:
In case we reach scheduler's limit, pfifo_tail_enqueue() will drop a
packet in scheduler's queue and decrease scheduler's qlen by one.
Then, pfifo_tail_enqueue() enqueue new packet and increase
scheduler's qlen by one. Finally, pfifo_tail_enqueue() return
`NET_XMIT_CN` status code.
Weird behaviour:
In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on a
scheduler that has no packet, the 'drop a packet' step will do nothing.
This means the scheduler's qlen still has value equal 0.
Then, we continue to enqueue new packet and increase scheduler's qlen by
one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by
one and return `NET_XMIT_CN` status code.
The problem is:
Let's say we have two qdiscs: Qdisc_A and Qdisc_B.
- Qdisc_A's type must have '->graft()' function to create parent/child relationship.
Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`.
- Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`.
- Qdisc_B is configured to have `sch->limit == 0`.
- Qdisc_A is configured to route the enqueued's packet to Qdisc_B.
Enqueue packet through Qdisc_A will lead to:
- hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B)
- Qdisc_B->q.qlen += 1
- pfifo_tail_enqueue() return `NET_XMIT_CN`
- hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A.
The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1.
Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem.
This violate the design where parent's qlen should equal to the sum of its childrens'qlen.
Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Willem de Bruijn <willemb@google.com>
[ Upstream commit a70c7b3cbc0688016810bb2e0b9b8a0d6a530045 ]
This reverts commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3.
The blamed commit caused a regression when neither tun->owner nor
tun->group is set. This is intended to be allowed, but now requires
CAP_NET_ADMIN.
Discussion in the referenced thread pointed out that the original
issue that prompted this patch can be resolved in userspace.
The relaxed access control may also make a device accessible when it
previously wasn't, while existing users may depend on it to not be.
This is a clean pure git revert, except for fixing the indentation on
the gid_valid line that checkpatch correctly flagged.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit 811b8f534fd85e17077bd2ac0413bcd16cc8fb9b ]
In case of tc offload, when user space queries the kernel for tc action
statistics, tc will query the offloaded statistics from device drivers.
Among other statistics, drivers are expected to pass the number of
packets that hit the action since the last query as a 64-bit number.
Unfortunately, tc treats the number of packets as a 32-bit number,
leading to truncation and incorrect statistics when the number of
packets since the last query exceeds 0xffffffff:
$ tc -s filter show dev swp2 ingress
filter protocol all pref 1 flower chain 0
filter protocol all pref 1 flower chain 0 handle 0x1
skip_sw
in_hw in_hw_count 1
action order 1: mirred (Egress Redirect to device swp1) stolen
index 1 ref 1 bind 1 installed 58 sec used 0 sec
Action statistics:
Sent 1133877034176 bytes 536959475 pkt (dropped 0, overlimits 0 requeues 0)
[...]
According to the above, 2111-byte packets were redirected which is
impossible as only 64-byte packets were transmitted and the MTU was
1500.
Fix by treating packets as a 64-bit number:
$ tc -s filter show dev swp2 ingress
filter protocol all pref 1 flower chain 0
filter protocol all pref 1 flower chain 0 handle 0x1
skip_sw
in_hw in_hw_count 1
action order 1: mirred (Egress Redirect to device swp1) stolen
index 1 ref 1 bind 1 installed 61 sec used 0 sec
Action statistics:
Sent 1370624380864 bytes 21416005951 pkt (dropped 0, overlimits 0 requeues 0)
[...]
Which shows that only 64-byte packets were redirected (1370624380864 /
21416005951 = 64).

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@redhat.com>
[ Upstream commit 41b996ce83bf944de5569d6263c8dbd5513e7ed0 ]
The RXRPC_CALL_SERVER_SECURING state doesn't really belong with the other
states in the call's state set as the other states govern the call's Rx/Tx
phase transition and govern when packets can and can't be received or
transmitted. The "Securing" state doesn't actually govern the reception of
packets and would need to be split depending on whether or not we've
received the last packet yet (to mirror RECV_REQUEST/ACK_REQUEST).
The "Securing" state is more about whether or not we can start forwarding
packets to the application as recvmsg will need to decode them and the
decoding can't take place until the challenge/response exchange has
completed.
Fix this by removing the RXRPC_CALL_SERVER_SECURING state from the state
set and, instead, using a flag, RXRPC_CALL_CONN_CHALLENGING, to track
whether or not we can queue the call for reception by recvmsg() or notify
the kernel app that data is ready. In the event that we've already
received all the packets, the connection event handler will poke the app
layer in the appropriate manner.
Also there's a race whereby the app layer sees the last packet before rxrpc
has managed to end the rx phase and change the state to one amenable to
allowing a reply. Fix this by queuing the packet after calling
rxrpc_end_rx_phase().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Kemnade <andreas@kemnade.info>
commit f1f010c9d9c62c865d9f54e94075800ba764b4d9 upstream.
This driver can be built as a module since commit 3b062a086984 ("cpufreq:
dt-platdev: Support building as module"), but unfortunately this caused
a regression because the cputfreq-dt-platdev.ko module does not autoload.
Usually, this is solved by just using the MODULE_DEVICE_TABLE() macro to
export all the device IDs as module aliases. But this driver is special
due how matches with devices and decides what platform supports.
There are two of_device_id lists, an allow list that are for CPU devices
that always match and a deny list that's for devices that must not match.
The driver registers a cpufreq-dt platform device for all the CPU device
nodes that either are in the allow list or contain an operating-points-v2
property and are not in the deny list.
Enforce builtin compile of cpufreq-dt-platdev to make autoload work.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pali Rohár <pali@kernel.org>
commit 25f6184e24b3991eae977a29ecf27d537cc930b2 upstream.
Check if the server honored ATTR_SYSTEM flag by CREATE_OPTION_SPECIAL
option. If not then server does not support ATTR_SYSTEM and newly
created file is not SFU compatible, which means that the call failed.
If CREATE was successful but either setting ATTR_SYSTEM failed or
writing type/data information failed then remove the intermediate
object created by CREATE. Otherwise intermediate empty object stay
on the server.
This ensures that if the creating of SFU files with system attribute is
unsupported by the server then no empty file stay on the server as a result
of unsupported operation.
This is for example case with Samba server and Linux tmpfs storage without
enabled xattr support (where Samba stores ATTR_SYSTEM bit).

------------------
From: Maarten Lankhorst <dev@lankhorst.se>
commit f4a9dd57e549a17a7dac1c1defec26abd7e5c2d4 upstream.
Tiled displays have a different x/y offset to begin with. Instead of
attempting to remember this, just apply a delta instead.
This fixes the first tile being duplicated on other tiles when vt
switching.

------------------
From: Maarten Lankhorst <dev@lankhorst.se>
commit 10026f536843eb8c9148ef6ffb4c6deeebc26838 upstream.
When testing on my tiled display, initially the tiled display is
detected correctly:
[90376.523692] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] fallback: Not all outputs enabled
[90376.523713] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] Enabled: 0, detected: 2
...
[90376.523967] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:82:pipe A] desired mode 1920x2160 set (1920,0)
[90376.524020] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:134:pipe B] desired mode 1920x2160 set (0,0)
But then, when modes have been set:
[90379.729525] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] [CONNECTOR:287:DP-4] on [CRTC:82:pipe A]: 1920x2160
[90379.729640] xe 0000:67:00.0: [drm:drm_client_firmware_config.isra.0 [drm]] [CONNECTOR:289:DP-5] on [CRTC:134:pipe B]: 1920x2160
...
[90379.730036] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:82:pipe A] desired mode 1920x2160 set (0,0)
[90379.730124] xe 0000:67:00.0: [drm:drm_client_modeset_probe [drm]] [CRTC:134:pipe B] desired mode 1920x2160 set (0,0)
Call drm_client_get_tile_offsets() in drm_client_firmware_config() as
well, to ensure that the offset is set correctly.
This has to be done as a separate pass, as the tile order may not be
equal to the drm connector order.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ruben Devos <devosruben6@gmail.com>
commit 11f8b80ab9f99291dc88d09855b9f8f43b772335 upstream.
The tracepoints based on smb3_inf_compound_*_class have tcon id and
session id swapped around. This results in incorrect output in
`trace-cmd report`.
Fix the order of arguments to resolve this issue. The trace-cmd output
below shows the before and after of the smb3_delete_enter and
smb3_delete_done events as an example. The smb3_cmd_* events show the
correct session and tcon id for reference.
Also fix tracepoint set -> get in the SMB2_OP_GET_REPARSE case.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meetakshi Setiya <msetiya@microsoft.com>
commit 57e4a9bd61c308f607bc3e55e8fa02257b06b552 upstream.
MS-SMB2 section 2.2.13.2.10 specifies that 'epoch' should be a 16-bit
unsigned integer used to track lease state changes. Change the data
type of all instances of 'epoch' from unsigned int to __u16. This
simplifies the epoch change comparisons and makes the code more
compliant with the protocol spec.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yu Kuai <yukuai3@huawei.com>
commit 127186cfb184eaccdfe948e6da66940cfa03efc5 upstream.
THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated
CONFIG_MD_LINEAR") because it has been marked as deprecated for a long
time.
However, md-linear is used widely for underlying disks with different size,
sadly we didn't know this until now, and it's true useful to create
partitions and assemble multiple raid and then append one to the other.
People have to use dm-linear in this case now, however, they will prefer
to minimize the number of involved modules.
Fixes: 849d18e27be9 ("md: Remove deprecated CONFIG_MD_LINEAR")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <hca@linux.ibm.com>
commit 26701574cee6777f867f89b4a5c667817e1ee0dd upstream.
The futex operation FUTEX_OP_ANDN is supposed to implement
*(int *)UADDR2 &= ~OPARG;
The s390 implementation just implements an AND instead of ANDN.
Add the missing bitwise not operation to oparg to fix this.
This is broken since nearly 19 years, so it looks like user space is
not making use of this operation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <maz@kernel.org>
commit 064737920bdbca86df91b96aed256e88018fef3a upstream.
The hwcaps code that exposes SVE features to userspace only
considers ID_AA64ZFR0_EL1, while this is only valid when
ID_AA64PFR0_EL1.SVE advertises that SVE is actually supported.
The expectations are that when ID_AA64PFR0_EL1.SVE is 0, the
ID_AA64ZFR0_EL1 register is also 0. So far, so good.
Things become a bit more interesting if the HW implements SME.
In this case, a few ID_AA64ZFR0_EL1 fields indicate *SME*
features. And these fields overlap with their SVE interpretations.
But the architecture says that the SME and SVE feature sets must
match, so we're still hunky-dory.
This goes wrong if the HW implements SME, but not SVE. In this
case, we end-up advertising some SVE features to userspace, even
if the HW has none. That's because we never consider whether SVE
is actually implemented. Oh well.
Fix it by restricting all SVE capabilities to ID_AA64PFR0_EL1.SVE
being non-zero. The HWCAPS documentation is amended to reflect the
actually checks performed by the kernel.
Fixes: 06a916feca2b ("arm64: Expose SVE2 features for userspace")

From: Thomas Zimmermann <tzimmermann@suse.de>
commit 53036937a101b5faeaf98e7438555fa854a1a844 upstream.
Including m68k's <asm/raw_io.h> in vga.h on nommu platforms results
in conflicting defines with io_no.h for various I/O macros from the
__raw_read and __raw_write families. An example error is

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nam Cao <namcao@linutronix.de>
commit ab251dacfbae28772c897f068a4184f478189ff2 upstream.
The field "eip" (instruction pointer) and "esp" (stack pointer) of a task
can be read from /proc/PID/stat. These fields can be interesting for
coredump.
However, these fields were disabled by commit 0a1eb2d474ed ("fs/proc: Stop
reporting eip and esp in /proc/PID/stat"), because it is generally unsafe
to do so. But it is safe for a coredumping process, and therefore
exceptions were made:
- for a coredumping thread by commit fd7d56270b52 ("fs/proc: Report
eip/esp in /prod/PID/stat for coredumping").
- for all other threads in a coredumping process by commit cb8f381f1613
("fs/proc/array.c: allow reporting eip/esp for all coredumping
threads").
The above two commits check the PF_DUMPCORE flag to determine a coredump thread
and the PF_EXITING flag for the other threads.
Unfortunately, commit 92307383082d ("coredump: Don't perform any cleanups
before dumping core") moved coredump to happen earlier and before PF_EXITING is
set. Thus, checking PF_EXITING is no longer the correct way to determine
threads in a coredumping process.
Instead of PF_EXITING, use PF_POSTCOREDUMP to determine the other threads.
Checking of PF_EXITING was added for coredumping, so it probably can now be
removed. But it doesn't hurt to keep.
Fixes: 92307383082d ("coredump: Don't perform any cleanups before dumping core")

commit 7c0be4ead1f8f5f8be0803f347de0de81e3b8e1c upstream.
sysfs ->store is called with queue freezed, meantime we have several
->store() callbacks(update_nr_requests, wbt, scheduler) to allocate
memory with GFP_KERNEL which may run into direct reclaim code path,
then potential deadlock can be caused.
Fix the issue by marking NOIO around sysfs ->store()

From: Dan Carpenter <dan.carpenter@linaro.org>
commit 55cf2f4b945f6a6416cc2524ba740b83cc9af25a upstream.
Most of these sizes and counts are capped at 256MB so the math doesn't
result in an integer overflow. The "relocs" count needs to be checked
as well. Otherwise on 32bit systems the calculation of "full_data"
could be wrong.
full_data = data_len + relocs * sizeof(unsigned long);

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xu Yang <xu.yang_2@nxp.com>
commit f3edf03a4c59e59e52c0c1fd958f64a76a038302 upstream.
The imx93 is the first supported DDR PMU that supports read transaction,
write transaction and read beats events which corresponding respecitively
to counter 2, 3 and 4.
However, transaction-based AXI match has low accuracy when get total bits
compared to beats-based. And imx93 doesn't assign AXI_ID to each master.
So axi filter is not used widely on imx93. This could be regards as AXI
filter version 1.
To improve the AXI filter capability, imx95 supports 1 read beats and 3
write beats event which corresponding respecitively to counter 2-5. imx95
also detailed AXI_ID allocation so that most of the master could be count
individually. This could be regards as AXI filter version 2.
This will introduce AXI filter version to refactor the driver and support
better extension, such as coming imx943. This is also a potential fix on
imx91 when configure axi filter.

commit 901dd2617c9c3554b2449c8844b6338009112fcf upstream.
Restore PCI state after putting the NPU in D0.
Restoring state before powering up the device caused a Qemu crash
if NPU was running in passthrough mode and recovery was performed.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
commit f0da16992aef7e246b2f3bba1492e3a52c38ca0e upstream.
When the host stage1 is configured for LPA2, the value currently being
programmed into TCR_EL2.T0SZ may be invalid unless LPA2 is configured
at HYP as well. This means kvm_lpa2_is_enabled() is not the right
condition to test when setting TCR_EL2.DS, as it will return false if
LPA2 is only available for stage 1 but not for stage 2.
Similary, programming TCR_EL2.PS based on a limited IPA range due to
lack of stage2 LPA2 support could potentially result in problems.
So use lpa2_is_enabled() instead, and set the PS field according to the
host's IPS, which is capped at 48 bits if LPA2 support is absent or
disabled. Whether or not we can make meaningful use of such a
configuration is a different question.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
commit 62cffa496aac0c2c4eeca00d080058affd7a0172 upstream.
When FEAT_LPA{,2} are not implemented, the ID_AA64MMFR0_EL1.PARange and
TCR.IPS values corresponding with 52-bit physical addressing are
reserved.
Setting the TCR.IPS field to 0b110 (52-bit physical addressing) has side
effects, such as how the TTBRn_ELx.BADDR fields are interpreted, and so
it is important that disabling FEAT_LPA2 (by overriding the
ID_AA64MMFR0.TGran fields) also presents a PARange field consistent with
that.
So limit the field to 48 bits unless LPA2 is enabled, and update
existing references to use the override consistently.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@kernel.org>
commit d3c7c48d004f6c8d892f39b5d69884fd0fe98c81 upstream.
In commit 892f7237b3ff ("arm64: Delay initialisation of
cpuinfo_arm64::reg_{zcr,smcr}") we moved access to ZCR, SMCR and SMIDR
later in the boot process in order to ensure that we don't attempt to
interact with them if SVE or SME is disabled on the command line.
Unfortunately when initialising the boot CPU in init_cpu_features() we work
on a copy of the struct cpuinfo_arm64 for the boot CPU used only during
boot, not the percpu copy used by the sysfs code. The expectation of the
feature identification code was that the ID registers would be read in
__cpuinfo_store_cpu() and the values not modified by init_cpu_features().
The main reason for the original change was to avoid early accesses to
ZCR on practical systems that were seen shipping with SVE reported in ID
registers but traps enabled at EL3 and handled as fatal errors, SME was
rolled in due to the similarity with SVE. Since then we have removed the
early accesses to ZCR and SMCR in commits:
abef0695f9665c3d ("arm64/sve: Remove ZCR pseudo register from cpufeature code")
391208485c3ad50f ("arm64/sve: Remove SMCR pseudo register from cpufeature code")
so only the SMIDR_EL1 part of the change remains. Since SMIDR_EL1 is
only trapped via FEAT_IDST and not the SME trap it is less likely to be
affected by similar issues, and the factors that lead to issues with SVE
are less likely to apply to SME.
Since we have not yet seen practical SME systems that need to use a
command line override (and are only just beginning to see SME systems at
all) and the ID register read is much more likely to be safe let's just
store SMIDR_EL1 along with all the other ID register reads in
__cpuinfo_store_cpu().
This issue wasn't apparent when testing on emulated platforms that do not
report values in SMIDR_EL1.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
commit bf74bb73cd87c64bd5afc1fd4b749029997b6170 upstream.
Currently, LPA2 kernel support implies support for up to 52 bits of
physical addressing, and this is reflected in global definitions such as
PHYS_MASK_SHIFT and MAX_PHYSMEM_BITS.
This is potentially problematic, given that LPA2 hardware support is
modeled as a CPU feature which can be overridden, and with LPA2 hardware
support turned off, attempting to map physical regions with address bits
[51:48] set (which may exist on LPA2 capable systems booting with
arm64.nolva) will result in corrupted mappings with a truncated output
address and bogus shareability attributes.
This means that the accepted physical address range in the mapping
routines should be at most 48 bits wide when LPA2 support is configured
but not enabled at runtime.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <maz@kernel.org>
commit b450dcce93bc2cf6d2bfaf5a0de88a94ebad8f89 upstream.
When updating the interrupt state for an emulated timer, we return
early and skip the setup of a soft timer that runs in parallel
with the guest.
While this is OK if we have set the interrupt pending, it is pretty
wrong if the guest moved CVAL into the future. In that case,
no timer is armed and the guest can wait for a very long time
(it will take a full put/load cycle for the situation to resolve).
This is specially visible with EDK2 running at EL2, but still
using the EL1 virtual timer, which in that case is fully emulated.
Any key-press takes ages to be captured, as there is no UART
interrupt and EDK2 relies on polling from a timer...
The fix is simply to drop the early return. If the timer interrupt
is pending, we will still return early, and otherwise arm the soft
timer.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <tzimmermann@suse.de>
commit 666e1960464140cc4bc9203c203097e70b54c95a upstream.
The code for detecting and updating the connector status in
cdn_dp_pd_event_work() has a number of problems.
- It does not aquire the locks to call the detect helper and update
the connector status. These are struct drm_mode_config.connection_mutex
and struct drm_mode_config.mutex.
- It does not use drm_helper_probe_detect(), which helps with the
details of locking and detection.
- It uses the connector's status field to determine a change to
the connector status. The epoch_counter field is the correct one. The
field signals a change even if the connector status' value did not
change.
Replace the code with a call to drm_connector_helper_hpd_irq_event(),
which fixes all these problems.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakob Unterwurzacher <jakobunt@gmail.com>
commit 9d241b06802c6c2176ae7aa4f9f17f8a577ed337 upstream.
During mass manufacturing, we noticed the mmc_rx_crc_error counter,
as reported by "ethtool -S eth0 | grep mmc_rx_crc_error", to increase
above zero during nuttcp speedtests. Most of the time, this did not
affect the achieved speed, but it prompted this investigation.
Cycling through the rx_delay range on six boards (see table below) of
various ages shows that there is a large good region from 0x12 to 0x35
where we see zero crc errors on all tested boards.
The old rx_delay value (0x10) seems to have always been on the edge for
the KSZ9031RNX that is usually placed on Puma.
Choose "rx_delay = 0x23" to put us smack in the middle of the good
region. This works fine as well with the KSZ9131RNX PHY that was used
for a small number of boards during the COVID chip shortages.

From: Robin Murphy <robin.murphy@arm.com>
commit 1dc7c8ed7cb378dd3974387692dfa833aee718d4 upstream.
It's no longer practical for the OMAP IOMMU driver to trick
arm_setup_iommu_dma_ops() into ignoring its presence, so let's use the
same tactic as other IOMMU API users on 32-bit ARM and explicitly kick
the arch code's dma_iommu_mapping out of the way to avoid problems.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chao Gao <chao.gao@intel.com>
commit 04bc93cf49d16d01753b95ddb5d4f230b809a991 upstream.
If KVM emulates an EOI for L1's virtual APIC while L2 is active, defer
updating GUEST_INTERUPT_STATUS.SVI, i.e. the VMCS's cache of the highest
in-service IRQ, until L1 is active, as vmcs01, not vmcs02, needs to track
vISR. The missed SVI update for vmcs01 can result in L1 interrupts being
incorrectly blocked, e.g. if there is a pending interrupt with lower
priority than the interrupt that was EOI'd.
This bug only affects use cases where L1's vAPIC is effectively passed
through to L2, e.g. in a pKVM scenario where L2 is L1's depriveleged host,
as KVM will only emulate an EOI for L1's vAPIC if Virtual Interrupt
Delivery (VID) is disabled in vmc12, and L1 isn't intercepting L2 accesses
to its (virtual) APIC page (or if x2APIC is enabled, the EOI MSR).
WARN() if KVM updates L1's ISR while L2 is active with VID enabled, as an
EOI from L2 is supposed to affect L2's vAPIC, but still defer the update,
to try to keep L1 alive. Specifically, KVM forwards all APICv-related
VM-Exits to L1 via nested_vmx_l1_wants_exit():
case EXIT_REASON_APIC_ACCESS:
case EXIT_REASON_APIC_WRITE:
case EXIT_REASON_EOI_INDUCED:
/*
* The controls for "virtualize APIC accesses," "APIC-
* register virtualization," and "virtual-interrupt
* delivery" only come from vmcs12.
*/
return true;

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Christopherson <seanjc@google.com>
commit 1e7381f3617d14b3c11da80ff5f8a93ab14cfc46 upstream.
Explicitly verify the target vCPU is fully online _prior_ to clamping the
index in kvm_get_vcpu(). If the index is "bad", the nospec clamping will
generate '0', i.e. KVM will return vCPU0 instead of NULL.
In practice, the bug is unlikely to cause problems, as it will only come
into play if userspace or the guest is buggy or misbehaving, e.g. KVM may
send interrupts to vCPU0 instead of dropping them on the floor.
However, returning vCPU0 when it shouldn't exist per online_vcpus is
problematic now that KVM uses an xarray for the vCPUs array, as KVM needs
to insert into the xarray before publishing the vCPU to userspace (see
commit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),
i.e. before vCPU creation is guaranteed to succeed.
As a result, incorrectly providing access to vCPU0 will trigger a
use-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()
bails out of vCPU creation due to an error and frees vCPU0. Commit
afb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, but
in doing so introduced an unsolvable teardown conundrum. Preventing
accesses to vCPU0 before it's fully online will allow reverting commit
afb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Keith Busch <kbusch@kernel.org>
commit 931656b9e2ff7029aee0b36e17780621948a6ac1 upstream.
Some libraries want to ensure they are single threaded before forking,
so making the kernel's kvm huge page recovery process a vhost task of
the user process breaks those. The minijail library used by crosvm is
one such affected application.
Defer the task to after the first VM_RUN call, which occurs after the
parent process has forked all its jailed processes. This needs to happen
only once for the kvm instance, so introduce some general-purpose
infrastructure for that, too. It's similar in concept to pthread_once;
except it is actually usable, because the callback takes a parameter.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Hildenbrand <david@redhat.com>
commit 5f230f41fdd9e799f43a699348dc572bca7159aa upstream.
We try to reuse the same vsie page when re-executing the vsie with a
given SCB address. The result is that we use the same shadow SCB --
residing in the vsie page -- and can avoid flushing the TLB when
re-running the vsie on a CPU.
So, when we allocate a fresh vsie page, or when we reuse a vsie page for
a different SCB address -- reusing the shadow SCB in different context --
we set ihcpu=0xffff to trigger the flush.
However, after we looked up the SCB address in the radix tree, but before
we grabbed the vsie page by raising the refcount to 2, someone could reuse
the vsie page for a different SCB address, adjusting page->index and the
radix tree. In that case, we would be reusing the vsie page with a
wrong page->index.
Another corner case is that we might set the SCB address for a vsie
page, but fail the insertion into the radix tree. Whoever would reuse
that page would remove the corresponding radix tree entry -- which might
now be a valid entry pointing at another page, resulting in the wrong
vsie page getting removed from the radix tree.
Let's handle such races better, by validating that the SCB address of a
vsie page didn't change after we grabbed it (not reuse for a different
SCB; the alternative would be performing another tree lookup), and by
setting the SCB address to invalid until the insertion in the tree
succeeded (SCB addresses are aligned to 512, so ULONG_MAX is invalid).
These scenarios are rare, the effects a bit unclear, and these issues were
only found by code inspection. Let's CC stable to be safe.

------------------
From: Dan Carpenter <dan.carpenter@linaro.org>
commit aab98e2dbd648510f8f51b83fbf4721206ccae45 upstream.
On 32bit systems the addition operations in ipc_msg_alloc() can
potentially overflow leading to memory corruption.
Add bounds checking using KSMBD_IPC_MAX_PAYLOAD to avoid overflow.

------------------
From: Aric Cyr <Aric.Cyr@amd.com>
commit 024771f3fb75dc817e9429d5763f1a6eb84b6f21 upstream.
[why]
Updating the cursor enablement register can be a slow operation and accumulates
when high polling rate cursors cause frequent updates asynchronously to the
cursor position.
[how]
Since the cursor enable bit is cached there is no need to update the
enablement register if there is no change to it. This removes the
read-modify-write from the cursor position programming path in HUBP and
DPP, leaving only the register writes.

commit 9078a5bfa21e78ae68b6d7c365d1b92f26720c55 upstream.
The following page fault was observed duringthe KFD process release.
In this particular error case, the HIP test (./MemcpyPerformance -h)
does not require the queue. As a result, the process_context_addr was
not assigned when the KFD process was released, ultimately leading to
this page fault during the execution of the function
kfd_process_dequeue_from_all_devices().

------------------
From: Jay Cornwall <jay.cornwall@amd.com>
commit f214b7beb00621b983e67ce97477afc3ab4b38f4 upstream.
The purpose of halt_if_hws_hang is to preserve GPU state for driver
debugging when queue preemption fails. Issuing per-queue reset may
kill wavefronts which caused the preemption failure.

commit 57965269896313e1629a518d3971ad55f599b792 upstream.
After the context is unpinned the backing memory can also be unpinned,
so any accesses via the lrc_reg_state pointer can end up in unmapped
memory. To avoid that, make sure to only access that memory if the
context is pinned when printing its info.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brian Geffon <bgeffon@google.com>
commit fa6182c8b13ebfdc70ebdc09161a70dd8131f3b1 upstream.
When converting to folios the cleanup path of shmem_get_pages() was
missed. When a DMA remap fails and the max segment size is greater than
PAGE_SIZE it will attempt to retry the remap with a PAGE_SIZEd segment
size. The cleanup code isn't properly using the folio apis and as a
result isn't handling compound pages correctly.
v2 -> v3:
(Ville) Just use shmem_sg_free_table() as-is in the failure path of
shmem_get_pages(). shmem_sg_free_table() will clear mapping unevictable
but it will be reset when it retries in shmem_sg_alloc_table().
v1 -> v2:
(Ville) Fixed locations where we were not clearing mapping unevictable.

From: Thomas Zimmermann <tzimmermann@suse.de>
commit fd39c41bcd82d5ebaaebadb944eab5598c668a90 upstream.
The ASTDP transmitter sometimes takes up to 1 second for enabling the
video signal, while the timeout is only 200 msec. This results in a
kernel error message. Increase the timeout to 1 second. An example

This is a cosmetical problem. Enabling the video signal still works
even with the error message. The problem has always been present, but
only recent versions of the ast driver warn about missing the timeout.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lucas De Marchi <lucas.demarchi@intel.com>
commit 042c48b73699c47d84b6ace73036e5a31a0d4cfc upstream.
Having the exec queue snapshot inside a "GuC CT" section was always
wrong. Commit c28fd6c358db ("drm/xe/devcoredump: Improve section
headings and add tile info") tried to fix that bug, but with that also
broke the mesa tool that parses the devcoredump, hence it was reverted
in commit a53da2fb25a3 ("drm/xe: Revert some changes that break a mesa
debug tool").
With the mesa tool also fixed, this can propagate as a fix on both
kernel and userspace side to avoid unnecessary headache for a debug
feature.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jani Nikula <jani.nikula@intel.com>
commit 230b19bc2bcc5897d0e20b4ce7e9790a469a2db0 upstream.
Commit 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best
compressed bpp") tries to find the best compressed bpp for the
link. However, it iterates from max to min bpp on display 13+, and from
min to max on other platforms. This presumably leads to minimum
compressed bpp always being chosen on display 11-12.
Iterate from high to low on all platforms to actually use the best
possible compressed bpp.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
commit c7b49506b3ba7a62335e6f666a43f67d5cd9fd1e upstream.
I'm seeing underruns with these 64bpp YUV formats on TGL.
The weird details:
- only happens on pipe B/C/D SDR planes, pipe A SDR planes
seem fine, as do all HDR planes
- somehow CDCLK related, higher CDCLK allows for bigger plane
with these formats without underruns. With 300MHz CDCLK I
can only go up to 1200 pixels wide or so, with 650MHz even
a 3840 pixel wide plane was OK
- ICL and ADL so far appear unaffected
So not really sure what's the deal with this, but bspec does
state "64-bit formats supported only on the HDR planes" so
let's just drop these formats from the SDR planes. We already
disallow 64bpp RGB formats.

commit 2255b40cacc2e5ef1b127770fc1808c60de4a2fc upstream.
Vulkan can't support DCC and Z/S compression on GFX12 without
WRITE_COMPRESS_DISABLE in this commit or a completely different DCC
interface.
AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lo-an Chen <lo-an.chen@amd.com>
commit e01f07cb92513ca4b9b219ab9caa34d607bc1e2d upstream.
[WHY]
When the system powers up eDP with external monitors in seamless boot
sequence, stutter get enabled before TTU and HUBP registers being
programmed, which resulting in underflow.
[HOW]
Enable TTU in hubp_init.
Change the sequence that do not perpare_bandwidth and optimize_bandwidth
while having seamless boot streams.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lucas De Marchi <lucas.demarchi@intel.com>
commit a9ab6591b45258b79af1cb66112fd9f83c8855da upstream.
Commit 70fb86a85dc9 ("drm/xe: Revert some changes that break a mesa
debug tool") partially reverted some changes to workaround breakage
caused to mesa tools. However, in doing so it also broke fetching the
GuC log via debugfs since xe_print_blob_ascii85() simply bails out.
The fix is to avoid the extra newlines: the devcoredump interface is
line-oriented and adding random newlines in the middle breaks it. If a
tool is able to parse it by looking at the data and checking for chars
that are out of the ascii85 space, it can still do so. A format change
that breaks the line-oriented output on devcoredump however needs better
coordination with existing tools.
v2: Add suffix description comment
v3: Reword explanation of xe_print_blob_ascii85() calling drm_puts()
in a loop

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fedor Pchelkin <pchelkin@ispras.ru>
commit 5f397409f8ee5bc82901eeaf799e1cbc4f8edcf1 upstream.
A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.
Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.

analysis tool.

From: Fedor Pchelkin <pchelkin@ispras.ru>
commit 5c61419e02033eaf01733d66e2fcd4044808f482 upstream.
One of the possible ways to enable the input MTU auto-selection for L2CAP
connections is supposed to be through passing a special "0" value for it
as a socket option. Commit [1] added one of those into avdtp. However, it
simply wouldn't work because the kernel still treats the specified value
as invalid and denies the setting attempt. Recorded BlueZ logs include the
following:
bluetoothd[496]: profiles/audio/avdtp.c:l2cap_connect() setsockopt(L2CAP_OPTIONS): Invalid argument (22)

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Gstir <david@sigma-star.at>
commit e8d9fab39d1f87b52932646b2f1e7877aa3fc0f4 upstream.
With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted
keys can crash during en- and decryption of the blob encryption key via
the DCP crypto driver. This is caused by improperly using sg_init_one()
with vmalloc'd stack buffers (plain_key_blob).
Fix this by always using kmalloc() for buffers we give to the DCP crypto
driver.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
commit 08bd5b7c9a2401faabdaa1472d45c7de0755fd7e upstream.
When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cody Eksal <masterr3c0rd@epochal.quest>
commit 16414720045de30945b8d14b7907e0cbf81a4b49 upstream.
While testing the MMC nodes proposed in [1], it was noted that mmc0/1
would fail to initialize, with "mmc: fatal err update clk timeout" in
the kernel logs. A closer look at the clock definitions showed that the MMC
MPs had the "CLK_SET_RATE_NO_REPARENT" flag set. No reason was given for
adding this flag in the first place, and its original purpose is unknown,
but it doesn't seem to make sense and results in severe limitations to MMC
speeds. Thus, remove this flag from the 3 MMC MPs.

------------------
From: Lubomir Rintel <lkundrak@v3.sk>
commit e24b15d4704dcb73920c3d18a6157abd18df08c1 upstream.
Setting the genpd's struct device's name with dev_set_name() is
happening within pm_genpd_init(). If it remains NULL, things can blow up
later, such as when crafting the devfs hierarchy for the power domain:
Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read
...
Call trace:
strlen from start_creating+0x90/0x138
start_creating from debugfs_create_dir+0x20/0x178
debugfs_create_dir from genpd_debug_add.part.0+0x4c/0x144

Bisecting tracks this crash back to commit 899f44531fe6 ("pmdomain: core:
Add GENPD_FLAG_DEV_NAME_FW flag"), which exchanges use of genpd->name
with dev_name(&genpd->dev) in genpd_debug_add.part().

UB9702 has the refclk freq register at a different offset than UB960,
but the code uses the UB960's offset for both chips. Fix this.
The refclk freq is only used for a debug print, so there's no functional

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Binbin Zhou <zhoubinbin@loongson.cn>
commit 5fb33b6797633ce60908d13dc06c54a101621845 upstream.
Since commit 02fb4f008433 ("clk: clk-loongson2: Fix potential buffer
overflow in flexible-array member access"), the clk provider register is
failed.
The count of `clks_num` is shown below:
for (p = data; p->name; p++)
clks_num++;
In fact, `clks_num` represents the number of SoC clocks and should be
expressed as the maximum value of the clock binding id in use (p->id + 1).
Now we fix it to avoid the following error when trying to register a clk
provider:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gabor Juhos <j4g8y7@gmail.com>
commit 33f1722eb86e45320a3dd7b3d42f6593a1d595c2 upstream.
Commit c45ae598fc16 ("clk: qcom: support for alpha mode configuration")
added support for configuring alpha mode, but it seems that the feature
was never working in practice.
The value of the alpha_{en,mode}_mask members of the configuration gets
added to the value parameter passed to the regmap_update_bits() function,
however the same values are not getting applied to the bitmask. As the
result, the respective bits in the USER_CTL register are never modifed
which leads to improper configuration of several PLLs.
The following table shows the PLL configurations where the 'alpha_en_mask'
member is set and which are passed as a parameter for the
clk_alpha_pll_configure() function. In the table the 'expected rate' column
shows the rate the PLL should run at with the given configuration, and
the 'real rate' column shows the rate the PLL runs at actually. The real
rates has been verified on hardwareOn IPQ* platforms, on other platforms,
those are computed values only.
file pll expected rate real rate
dispcc-qcm2290.c disp_cc_pll0 768.0 MHz 768.0 MHz

gcc-qcm2290.c gpll8 533.2 MHz != 518.4 MHz
gcc-qcs404.c gpll3 921.6 MHz 921.6 MHz
gcc-sm6115.c gpll11 600.0 MHz != 595.2 MHz
gcc-sm6115.c gpll8 800.0 MHz != 787.2 MHz
gpucc-sdm660.c gpu_cc_pll0 800.0 MHz != 787.2 MHz
gpucc-sdm660.c gpu_cc_pll1 740.0 MHz != 729.6 MHz
gpucc-sm6115.c gpu_cc_pll0 1200.0 MHz != 1190.4 MHz
gpucc-sm6115.c gpu_cc_pll1 640.0 MHz != 633.6 MHz
gpucc-sm6125.c gpu_pll0 1020.0 MHz != 1017.6 MHz
gpucc-sm6125.c gpu_pll1 930.0 MHz != 921.6 MHz
mmcc-sdm660.c mmpll8 930.0 MHz != 921.6 MHz
mmcc-sdm660.c mmpll5 825.0 MHz != 806.4 MHz
As it can be seen from the above, there are several PLLs which are
configured incorrectly.
Change the code to apply both 'alpha_en_mask' and 'alpha_mode_mask'
values to the bitmask in order to configure the alpha mode correctly.
Applying the 'alpha_en_mask' fixes the initial rate of the PLLs showed
in the table above. Since the 'alpha_mode_mask' is not used by any driver
currently, that part of the change causes no functional changes.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
commit 967e011013eda287dbec9e8bd3a19ebe730b8a08 upstream.
With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This
can happen during scenarios such as system suspend and breaks the resume
of PCIe controllers from suspend.
So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs
during gdsc_disable() and allow the hardware to transition the GDSCs to
retention when the parent domain enters low power state during system
suspend.

------------------
From: Daniel Golle <daniel@makrotopia.org>
commit 7c8746126a4e256fcf1af9174ee7d92cc3f3bc31 upstream.
Commit 973d1607d936 ("clk: mediatek: mt2701: use mtk_clk_simple_probe to
simplify driver") broke DT bindings as the highest index was reduced by
1 because the id count starts from 1 and not from 0.
Fix this, like for other drivers which had the same issue, by adding a
dummy clk at index 0.

From: Daniel Golle <daniel@makrotopia.org>
commit 5fba40be5fbad563914e3ce9d5129a6baaea1ff5 upstream.
Some of the audio subsystem clocks defined in clk-mt2701.h aren't
actually used by the driver. This broke conversion to
mtk_clk_simple_probe which expects that the highest possible clk id is
defined by the ARRAY_SIZE.
Add additional dummy clocks to fill the gaps and remain compatible with
the existing DT bindings.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eyal Birger <eyal.birger@gmail.com>
commit cf6cb56ef24410fb5308f9655087f1eddf4452e6 upstream.
When attaching uretprobes to processes running inside docker, the attached
process is segfaulted when encountering the retprobe.
The reason is that now that uretprobe is a system call the default seccomp
filters in docker block it as they only allow a specific set of known
syscalls. This is true for other userspace applications which use seccomp
to control their syscall surface.
Since uretprobe is a "kernel implementation detail" system call which is
not used by userspace application code directly, it is impractical and
there's very little point in forcing all userspace applications to
explicitly allow it in order to avoid crashing tracked processes.
Pass this systemcall through seccomp without depending on configuration.
Note: uretprobe is currently only x86_64 and isn't expected to ever be
supported in i386.
Fixes: ff474a78cef5 ("uprobe: Add uretprobe syscall to speed up return probe")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zijun Hu <quic_zijuhu@quicinc.com>
commit d1248436cbef1f924c04255367ff4845ccd9025e upstream.
blkcg_fill_root_iostats() iterates over @block_class's devices by
class_dev_iter_(init|next)(), but does not end iterating with
class_dev_iter_exit(), so causes the class's subsystem refcount leakage.
Fix by ending the iterating with class_dev_iter_exit().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
commit 8ba14d9f490aef9fd535c04e9e62e1169eb7a055 upstream.
GCC 15 changed the default C standard version to C23, which should not
have impacted the kernel because it requests the gnu11 standard via
'-std=' in the main Makefile. However, the EFI libstub Makefile uses its
own set of KBUILD_CFLAGS for x86 without a '-std=' value (i.e., using
the default), resulting in errors from the kernel's definitions of bool,
true, and false in stddef.h, which are reserved keywords under C23.
./include/linux/stddef.h:11:9: error: expected identifier before ‘false’
11 | false = 0,
./include/linux/types.h:35:33: error: two or more data types in declaration specifiers
35 | typedef _Bool bool;
Set '-std=gnu11' in the x86 cflags to resolve the error and consistently
use the same C standard version for the entire kernel. All other
architectures reuse KBUILD_CFLAGS from the rest of the kernel, so this
issue is not visible for them.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dave Young <dyoung@redhat.com>
commit 64b45dd46e154ee7641d7e0457f3fa266e57179f upstream.
efi_memattr_init() added a sanity check to avoid firmware caused corruption.
The check is based on efi memmap entry numbers, but kexec only takes the
runtime related memmap entries thus this caused many false warnings, see
below thread for details:
https://lore.kernel.org/all/20250108215957.3437660-2-usamaarif642@gmail.com/
Ard suggests to skip the efi memattr table in kexec, this makes sense because
those memattr fixups are not critical.
Fixes: 8fbe4c49c0cc ("efi/memattr: Ignore table if the size is clearly bogus")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuan-Wei Chiu <visitorckw@gmail.com>
commit 62892e77b8a64b9dc0e1da75980aa145347b6820 upstream.
The comparison function cmpworker() violates the C standard's
requirements for qsort() comparison functions, which mandate symmetry
and transitivity:
Symmetry: If x < y, then y > x.
Transitivity: If x < y and y < z, then x < z.
In its current implementation, cmpworker() incorrectly returns 0 when
w1->tid < w2->tid, which breaks both symmetry and transitivity. This
violation causes undefined behavior, potentially leading to issues such
as memory corruption in glibc [1].
Fix the issue by returning -1 when w1->tid < w2->tid, ensuring
compliance with the C standard and preventing undefined behavior.

From: Zijun Hu <quic_zijuhu@quicinc.com>
commit e4c00c9b1f70cd11792ff5b825899a6ee0234a62 upstream.
API of_parse_phandle_with_args_map() will use wrong input for nexus node
Nexus_2 as shown below:
Node_1 Nexus_1 Nexus_2
&Nexus_1,arg_1 -> arg_1,&Nexus_2,arg_2' -> &Nexus_2,arg_2 -> arg_2,...
map-pass-thru=<...>
Nexus_1's output arg_2 should be used as input of Nexus_2, but the API
wrongly uses arg_2' instead which != arg_2 due to Nexus_1's map-pass-thru.
Fix by always making @match_array point to @initial_match_array into
which to store nexus output.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zijun Hu <quic_zijuhu@quicinc.com>
commit b9e58c934c56aa35b0fb436d9afd86ef326bae0e upstream.
of_find_node_opts_by_path() fails to find OF device node when its
@path parameter have pattern below:
"alias-name/node-name-1/.../node-name-N:options".
The reason is that alias name length calculated by the API is wrong, as
explained by example below:
"testcase-alias/phandle-tests/consumer-a:testaliasoption".
^ ^ ^
0 14 39
The right length of alias 'testcase-alias' is 14, but the result worked
out by the API is 39 which is obvious wrong.
Fix by using index of either '/' or ':' as the length who comes earlier.
Fixes: 75c28c09af99 ("of: add optional options parameter to of_find_node_by_path()")

commit 267b21d0bef8e67dbe6c591c9991444e58237ec9 upstream.
According to DT spec, size of property 'alignment' is based on parent
node’s #size-cells property.
But __reserved_mem_alloc_size() wrongly uses @dt_root_addr_cells to get
the property obviously.
Fix by using @dt_root_size_cells instead of @dt_root_addr_cells.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Stuebner <heiko@sntech.de>
commit 8a5b38c3fd709e8acd2bfdedf66c25e6af759576 upstream.
The hid-sensor-hub creates the individual device structs and transfers them
to the created mfd platform-devices via the platform_data in the mfd_cell.
Before e651a1da442a ("HID: hid-sensor-hub: Allow parallel synchronous reads")
the sensor-hub was managing access centrally, with one "completion" in the
hub's data structure, which needed to be finished on removal at the latest.
The mentioned commit then moved this central management to each hid sensor
device, resulting on a completion in each struct hid_sensor_hub_device.
The remove procedure was adapted to go through all sensor devices and
finish any pending "completion".
What this didn't take into account was, platform_device_add_data() that is
used by mfd_add{_hotplug}_devices() does a kmemdup on the submitted
platform-data. So the data the platform-device gets is a copy of the
original data, meaning that the device worked on a different completion
than what sensor_hub_remove() currently wants to access.
To fix that, use device_for_each_child() to go through each child-device
similar to how mfd_remove_devices() unregisters the devices later and
with that get the live platform_data to finalize the correct completion.

Some architectures can not safely do atomic64 operations in NMI context.
Since the ring buffer relies on atomic64 operations to do its time
keeping, if an event is requested in NMI context, reject it for these
architectures.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt <rostedt@goodmis.org>
commit 6c8ad3ab45ad0e94bfb7a9c71f2fa9c6cacea4b2 upstream.
raw_spin_locks can be traced by lockdep or tracing itself. Atomic64
operations can be used in the tracing infrastructure. When an architecture
does not have true atomic64 operations it can use the generic version that
disables interrupts and uses spin_locks.
The tracing ring buffer code uses atomic64 operations for the time
keeping. But because some architectures use the default operations, the
locking inside the atomic operations can cause an infinite recursion.
As atomic64 implementation is architecture specific, it should not be
using raw_spin_locks() but instead arch_spin_locks as that is the purpose
of arch_spin_locks. To be used in architecture specific implementations of
generic infrastructure like atomic64 operations.
Note, by switching from raw_spin_locks to arch_spin_locks, the locks taken
to emulate the atomic64 operations will not have lockdep, mmio, or any
kind of checks done on them. They will not even disable preemption,
although the code will disable interrupts preventing the tasks that hold
the locks from being preempted. As the locks held are done so for very
short periods of time, and the logic is only done to emulate atomic64, not
having them be instrumented should not be an issue.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bitterblue Smith <rtl8821cerfe2@gmail.com>
commit 66ef0289ac99e155d206ddaa0fdfad09ae3cd007 upstream.
RTL8821AE is stuck transmitting at the lowest rate allowed by the rate
mask. This is because the firmware doesn't know the device is connected
to a network.
Fix the macros SET_H2CCMD_MSRRPT_PARM_OPMODE and
SET_H2CCMD_MSRRPT_PARM_MACID_IND to work on the first byte of __cmd,
not the second. Now the firmware is correctly notified when the device
is connected to a network and it activates the rate control.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marcel Hamer <marcel.hamer@windriver.com>
commit 68abd0c4ebf24cd499841a488b97a6873d5efabb upstream.
On removal of the device or unloading of the kernel module a potential NULL
pointer dereference occurs.
The following sequence deletes the interface:
brcmf_detach()
brcmf_remove_interface()
brcmf_del_if()
Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to
BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches.
After brcmf_remove_interface() call the brcmf_proto_detach() function is
called providing the following sequence:
brcmf_detach()
brcmf_proto_detach()
brcmf_proto_msgbuf_detach()
brcmf_flowring_detach()
brcmf_msgbuf_delete_flowring()
brcmf_msgbuf_remove_flowring()
brcmf_flowring_delete()
brcmf_get_ifp()
brcmf_txfinalize()
Since brcmf_get_ip() can and actually will return NULL in this case the
call to brcmf_txfinalize() will result in a NULL pointer dereference inside
brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors.
This will only happen if a flowring still has an skb.
Although the NULL pointer dereference has only been seen when trying to
update the tx statistic, all other uses of the ifp pointer have been
guarded as well with an early return if ifp is NULL.

Tested on Pinephone (RTL8723CS), random disconnections became rare,
instead of a frequent nuisance.

------------------
From: Shayne Chen <shayne.chen@mediatek.com>
commit 57af267d2b8f5d88485c6372761386d79c5e6a1a upstream.
Due to a limitation in available memory, the MT7916 firmware can only
handle either 5 GHz or 6 GHz at a time. It does not support runtime
switching without a full restart.
On older firmware, this accidentally worked to some degree due to missing
checks, but couldn't be supported properly, because it left the 6 GHz
channels uncalibrated.
Newer firmware refuses to start on either band if the passed EEPROM
data indicates support for both.
Deal with this limitation by using a module parameter to specify the
preferred band in case both are supported.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vasily Khoruzhick <anarsoul@gmail.com>
commit a806a8160a0fcaff368bb510c8a52eff37faf727 upstream.
Fix 3 typos in 8703b driver. 2 typos in calibration routines are not
fatal and do not seem to have any impact, just fix them to match vendor
driver.
However the last one in rtw8703b_set_channel_bb() clears too many bits
in REG_OFDM0_TX_PSD_NOISE, causing TX and RX issues (neither rate goes
above MCS0-MCS1). Vendor driver clears only 2 most significant bits.
With the last typo fixed, the driver is able to reach MCS7 on Pinebook

------------------
From: Foster Snowhill <forst@pen.gy>
commit c219427ed296f94bb4b91d08626776dc7719ee27 upstream.
Originally, it was possible for the DPE length check to overflow if
wDatagramIndex + wDatagramLength > U16_MAX. This could lead to an OoB
read.
Move the wDatagramIndex term to the other side of the inequality.
An existing condition ensures that wDatagramIndex < urb->actual_length.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Foster Snowhill <forst@pen.gy>
commit 86586dcb75cb8fd062a518aca8ee667938b91efb upstream.
Original code allowed for the start of NDP16 to be anywhere within the
URB based on the `wNdpIndex` value in NTH16. Only the start position of
NDP16 was checked, so it was possible for even the fixed-length part
of NDP16 to extend past the end of URB, leading to an out-of-bounds
read.
On iOS devices, the NDP16 header always directly follows NTH16. Rely on
and check for this specific format.
This, along with NCM-specific minimal URB length check that already
exists, will ensure that the fixed-length part of NDP16 plus a set
amount of DPEs fit within the URB.
Note that this commit alone does not fully address the OoB read.
The limit on the amount of DPEs needs to be enforced separately.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Foster Snowhill <forst@pen.gy>
commit 429fa68b58cefb9aa9de27e4089637298b46b757 upstream.
By definition, a DPE points at the start of a network frame/datagram.
Thus it makes no sense for it to point at anything that's part of the
NCM header. It is not a security issue, but merely an indication of
a malformed DPE.
Enforce that all DPEs point at the data portion of the URB, past the
NCM header.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Foster Snowhill <forst@pen.gy>
commit 2a9a196429e98fcc64078366c2679bc40aba5466 upstream.
Introduce an rx_error label to reduce repetitions in the header
signature checks.
Store wDatagramIndex and wDatagramLength after endianness conversion to
avoid repeated le16_to_cpu() calls.
Rewrite the loop to return on a null trailing DPE, which is required
by the CDC NCM spec. In case it is missing, fall through to rx_error.
This change does not fix any particular issue. Its purpose is to
simplify a subsequent commit that fixes a potential OoB read by limiting
the maximum amount of processed DPEs.

------------------
From: Foster Snowhill <forst@pen.gy>
commit efcbc678a14be268040ffc1fa33c98faf2d55141 upstream.
Originally, the total NCM header size was computed as the sum of two
vaguely labelled constants. While accurate, it wasn't particularly clear
where they were coming from.
Use sizes of existing NCM structs where available. Define the total
NDP16 size based on the maximum amount of DPEs that can fit into the
iOS-specific fixed-size header.
This change does not fix any particular issue. Rather, it introduces
intermediate constants that will simplify subsequent commits.
It should also make it clearer for the reader where the constant values
come from.

Clarify that the "NCM" implementation in `ipheth` is very limited, as
iOS devices aren't compatible with the CDC NCM specification in regular
tethering mode.
For a standards-compliant implementation, one shall turn to
the `cdc_ncm` module.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephan Gerhold <stephan.gerhold@linaro.org>
commit 4861ba7cf5a49969dee258dda2bf8d4e819135d1 upstream.
On the X1E80100 QCP, &vreg_l3e_1p2 only powers &usb_mp_qmpphy0/1
(i.e. USBSS_3 and USBSS_4). The QMP PHYs for USB_0, USB_1 and USB_2
are actually powered by &vreg_l2j_1p2.

------------------
From: Abel Vesa <abel.vesa@linaro.org>
commit 680421056216efe727ff4ed48f481691d5873b9e upstream.
Back when the CRD support was brought up, the usb_2 controller didn't
have anything connected to it in order to test it properly, so it was
never enabled.
On the Lenovo ThinkPad T14s, the usb_2 controller has the fingerprint
controller connected to it. So enabling it, proved that the interrupts
lines were wrong from the start.
Fix both the pwr_event and the DWC ctrl_irq lines, according to
documentation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
commit 541011dc2d7c4c82523706f726f422a5e23cc86f upstream.
The stop trigger invokes rz_ssi_stop() and rz_ssi_stream_quit().
- The purpose of rz_ssi_stop() is to disable TX/RX, terminate DMA
transactions, and set the controller to idle.
- The purpose of rz_ssi_stream_quit() is to reset the substream-specific
software data by setting strm->running and strm->substream appropriately.
The function rz_ssi_is_stream_running() checks if both strm->substream and
strm->running are valid and returns true if so. Its implementation is as
follows:
static inline bool rz_ssi_is_stream_running(struct rz_ssi_stream *strm)
{
return strm->substream && strm->running;
}
When the controller is configured in full-duplex mode (with both playback
and capture active), the rz_ssi_stop() function does not modify the
controller settings when called for the first substream in the full-duplex
setup. Instead, it simply sets strm->running = 0 and returns if the
companion substream is still running. The following code illustrates this:
static int rz_ssi_stop(struct rz_ssi_priv *ssi, struct rz_ssi_stream *strm)
{
strm->running = 0;
if (rz_ssi_is_stream_running(&ssi->playback) ||
rz_ssi_is_stream_running(&ssi->capture))
return 0;
// ...
}
The controller settings, along with the DMA termination (for the last
stopped substream), are only applied when the last substream in the
full-duplex setup is stopped.
While applying the controller settings only when the last substream stops
is not problematic, terminating the DMA operations for only one substream
causes failures when starting and stopping full-duplex operations multiple
times in a loop.
To address this issue, call dmaengine_terminate_async() for both substreams
involved in the full-duplex setup when the last substream in the setup is
stopped.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@linaro.org>
commit 82a0a3e6f8c02b3236b55e784a083fa4ee07c321 upstream.
My static checker rule complains about this code. The concern is that
if "sample_space" is negative then the "sample_space >= runtime->channels"
condition will not work as intended because it will be type promoted to a
high unsigned int value.
strm->fifo_sample_size is SSI_FIFO_DEPTH (32). The SSIFSR_TDC_MASK is
0x3f. Without any further context it does seem like a reasonable warning
and it can't hurt to add a check for negatives.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephan Gerhold <stephan.gerhold@linaro.org>
commit 22cf4fae6660b6e1a583a41cbf84e3046ca9ccd0 upstream.
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
commit eaeee4225dba30bef4d424bdf134a07b7f423e8b upstream.
The port_cfg object is used by serial_console_write(), which serves as
the write function for the earlycon device. Marking port_cfg as __initdata
causes it to be freed after kernel initialization, resulting in earlycon
becoming unavailable thereafter. Remove the __initdata macro from port_cfg
to resolve this issue.

commit 9f7dea875cc7f9c1a56a5c688290634a59cd1420 upstream.
In the sh-sci driver, sci_ports[0] is used by earlycon. If the earlycon is
still active when sci_probe() is called and the new serial port is supposed
to map to sci_ports[0], return -EBUSY to prevent breaking the earlycon.
This situation should occurs in debug scenarios, and users should be

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tiezhu Yang <yangtiezhu@loongson.cn>
commit 531936dee53e471a3ec668de3c94ca357f54b7e8 upstream.
The maximum number of load/store watchpoints and fetch instruction
watchpoints is 14 each according to LoongArch Reference Manual, so
extend the maximum number of watchpoints from 8 to 14 for ptrace.
By the way, just simply change 8 to 14 for the definition in struct
user_watch_state at the beginning, but it may corrupt uapi, then add
a new struct user_watch_state_v2 directly.
As far as I can tell, the only users for this struct in the userspace
are GDB and LLDB, there are no any problems of software compatibility
between the application and kernel according to the analysis.
The compatibility problem has been considered while developing and
testing. When the applications in the userspace get watchpoint state,
the length will be specified which is no bigger than the sizeof struct
user_watch_state or user_watch_state_v2, the actual length is assigned
as the minimal value of the application and kernel in the generic code
of ptrace:
kernel/ptrace.c: ptrace_regset():
kiov->iov_len = min(kiov->iov_len,
(__kernel_size_t) (regset->n * regset->size));
if (req == PTRACE_GETREGSET)
return copy_regset_to_user(task, view, regset_no, 0,
kiov->iov_len, kiov->iov_base);
else
return copy_regset_from_user(task, view, regset_no, 0,
kiov->iov_len, kiov->iov_base);
For example, there are four kind of combinations, all of them work well.
(1) "older kernel + older gdb", the actual length is 8+(8+8+4+4)*8=200;
(2) "newer kernel + newer gdb", the actual length is 8+(8+8+4+4)*14=344;
(3) "older kernel + newer gdb", the actual length is 8+(8+8+4+4)*8=200;
(4) "newer kernel + older gdb", the actual length is 8+(8+8+4+4)*8=200.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Narayana Murty N <nnmlinux@linux.ibm.com>
commit 11b93559000c686ad7e5ab0547e76f21cc143844 upstream.
The PE Reset State "0" returned by RTAS calls
"ibm_read_slot_reset_[state|state2]" indicates that the reset is
deactivated and the PE is in a state where MMIO and DMA are allowed.
However, the current implementation of "pseries_eeh_get_state()" does
not reflect this, causing drivers to incorrectly assume that MMIO and
DMA operations cannot be resumed.
The userspace drivers as a part of EEH recovery using VFIO ioctls fail
to detect when the recovery process is complete. The VFIO_EEH_PE_GET_STATE
ioctl does not report the expected EEH_PE_STATE_NORMAL state, preventing
userspace drivers from functioning properly on pseries systems.
The patch addresses this issue by updating 'pseries_eeh_get_state()'
to include "EEH_STATE_MMIO_ENABLED" and "EEH_STATE_DMA_ENABLED" in
the result mask for PE Reset State "0". This ensures correct state
reporting to the callers, aligning the behavior with the PAPR specification
and fixing the bug in EEH recovery for VFIO user workflows.

------------------
From: Hou Tao <houtao1@huawei.com>
commit 9fdbbdbbc92b1474a87b89f8b964892a63734492 upstream.
The updates of io->sector are the leftovers when dm-crypt allocated
pages for partial write request. However, since commit cf2f1abfbd0db
("dm crypt: don't allocate pages for a partial request"), there is no
partial request anymore.
After the introduction of write request rb-tree, the updates of
io->sectors may interfere the insertion procedure, because ->sectors of
these write requests which have already been added in the rb-tree may be
changed during the insertion of new write request.
Fix it by removing these buggy updates of io->sectors. Considering these
updates only effect the write request rb-tree, the commit which
introduces the write request rb-tree is used as the fix tag.

------------------
From: Hou Tao <houtao1@huawei.com>
commit 8b8f8037765757861f899ed3a2bfb34525b5c065 upstream.
dm-crypt uses tag_offset to index the integrity metadata for each crypt
sector. When the initial crypt_convert() returns BLK_STS_DEV_RESOURCE,
dm-crypt will try to continue the crypt/decrypt procedure in a kworker.
However, it resets tag_offset as zero instead of using the tag_offset
related with current sector. It may return unexpected data when using
random IV or return unexpected integrity related error.
Fix the problem by tracking tag_offset in per-IO convert_context.
Therefore, when the crypt/decrypt procedure continues in a kworker, it
could use the next tag_offset saved in convert_context.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mateusz Jończyk <mat.jonczyk@o2.pl>
commit 42a39e4aa59a10aa4afdc14194f3ee63d2db94e1 upstream.
Currently, installation of Debian 12.8 for mipsel fails on machines
without an FPU [1]. This is caused by the fact that zstd (which is used
for initramfs compression) executes the prefx instruction, which is not
emulated properly by the kernel.
The prefx (Prefetch Indexed) instruction fetches data from memory into
the cache without any side effects. Though functionally unrelated, it
requires an FPU [2].
Bytecode format of this instruction ends on "001111" binary:
(prefx instruction format) & 0x0000003f = 0x0000000f
The code in fpux_emu() runs like so:
#define MIPSInst(x) x
#define MIPSInst_FMA_FFMT(x) (MIPSInst(x) & 0x00000007)
#define MIPSInst_FUNC(x) (MIPSInst(x) & 0x0000003f)
enum cop1x_func { ..., pfetch_op = 0x0f, ... };
...
switch (MIPSInst_FMA_FFMT(ir)) {
...
case 0x3:
if (MIPSInst_FUNC(ir) != pfetch_op)
return SIGILL;
/* ignore prefx operation */
break;
default:
return SIGILL;
}
That snippet above contains a logic error and the
if (MIPSInst_FUNC(ir) != pfetch_op)
comparison always fires.
When MIPSInst_FUNC(ir) is equal to pfetch_op, ir must end on 001111
binary. In this case, MIPSInst_FMA_FFMT(ir) must be equal to 0x7, which
does not match that case label.
This causes emulation failure for the prefx instruction. Fix it.
This has been broken by
commit 919af8b96c89 ("MIPS: Make definitions of MIPSInst_FMA_{FUNC,FMTM} consistent with MIPS64 manual")
which modified the MIPSInst_FMA_FFMT macro without updating the users.

From: Xi Ruoyao <xry111@xry111.site>
commit 078b831638e1aa06dd7ffa9f244c8ac6b2995561 upstream.
This reverts commit 426fa8e4fe7bb914b5977cbce453a9926bf5b2e6.
The commit has caused two issues on Loongson 3A4000:
1. The timestamp in dmesg become erratic, like:
[3.736957] amdgpu 0000:04:00.0: ... ...
[3.748895] [drm] Initialized amdgpu ... ...
[18446744073.381141] amdgpu 0000:04:00:0: ... ...
[1.613326] igb 0000:03:00.0 enp3s0: ... ...
2. More seriously, some workloads (for example, the test
stdlib/test-cxa_atexit2 in the Glibc test suite) triggers an RCU
stall and hang the system with a high probably (4 hangs out of 5
tests).
Revert this commit to use jiffie on Loongson MIPS systems and fix these
issues for now. The root cause may need more investigation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Axboe <axboe@kernel.dk>
commit b13ee668e8280ca5b07f8ce2846b9957a8a10853 upstream.
blkdev_read_iter() has a few odd checks, like gating the position and
count adjustment on whether or not the result is bigger-than-or-equal to
zero (where bigger than makes more sense), and not checking the return
value of blkdev_direct_IO() before doing an iov_iter_revert(). The
latter can lead to attempting to revert with a negative value, which
when passed to iov_iter_revert() as an unsigned value will lead to
throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT.
Be sane and don't revert for -EIOCBQUEUED, like what is done in other
spots.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@igalia.com>
commit 8004d635f27bbccaa5c083c50d4d5302a6ffa00e upstream.
This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195.
Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera,
with ID 1b3f:2002, stopped being detected:
$ ls -l /dev/video*
zsh: no matches found: /dev/video*
[ 7.230599] usb 3-2: Found multiple Units with ID 5
This particular device is non-compliant, having both the Output Terminal
and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build
a chain. However, when media elements are added and uvc_mc_create_links
call uvc_entity_by_id, it will get the incorrect entity,
media_create_pad_link will WARN, and it will fail to register the entities.
In order to reinstate support for such devices in a timely fashion,
reverting the fix for these warnings is appropriate. A proper fix that
considers the existence of such non-compliant devices will be submitted in
a later development cycle.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 0a744cceebd0480cb39587b3b1339d66a9d14063 upstream.
Commit 2e4955167ec5 ("firmware: qcom: scm: Fix __scm and waitq
completion variable initialization") introduced a write barrier in probe
function to store global '__scm' variable. It also claimed that it
added a read barrier, because as we all known barriers are paired (see
memory-barriers.txt: "Note that write barriers should normally be paired
with read or address-dependency barriers"), however it did not really
add it.
The offending commit used READ_ONCE() to access '__scm' global which is
not a barrier.
The barrier is needed so the store to '__scm' will be properly visible.
This is most likely not fatal in current driver design, because missing
read barrier would mean qcom_scm_is_available() callers will access old
value, NULL. Driver does not support unbinding and does not correctly
handle probe failures, thus there is no risk of stale or old pointer in
'__scm' variable.
However for code correctness, readability and to be sure that we did not
mess up something in this tricky topic of SMP barriers, add a read
barrier for accessing '__scm'. Change also comment from useless/obvious
what does barrier do, to what is expected: which other parts of the code
are involved here.

commit b628510397b5cafa1f5d3e848a28affd1c635302 upstream.
Commit 2e4955167ec5 ("firmware: qcom: scm: Fix __scm and waitq
completion variable initialization") introduced a write barrier in probe
function to store global '__scm' variable. We all known barriers are
paired (see memory-barriers.txt: "Note that write barriers should
normally be paired with read or address-dependency barriers"), therefore
accessing it from concurrent contexts requires read barrier. Previous
commit added such barrier in qcom_scm_is_available(), so let's use that
directly.
Lack of this read barrier can result in fetching stale '__scm' variable
value, NULL, and dereferencing it.
Note that barrier in qcom_scm_is_available() satisfies here the control
dependency.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 0f3a822ae2254a1e7ce3a130a1efd94e2cab73ee upstream.
The recent cleanup of the quirk table entries with the codec ID
matching caused a regression on some Lenovo Legion 7 models with PCI
SSID 17aa:386f: it assumed wrongly as if the codec SSID on the machine
were also 17aa:386f, but in this case, it was 17aa:38a8. This made
the binding with a wrong sub-codec, instead of TAS2781, the Cirrus
codec was bound.
For addressing the regression, correct the quirk entry to the right
value 17aa:38a8.
Note that this makes the entry appearing in an unsorted position.
This exception is needed because the entry must match before the PCI
SSID 17aa:386f.
Also there is another entry for 17aa:38a8, but the latter is for PCI
SSID matching while the new entry is for the codec SSID matching.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuan-Wei Chiu <visitorckw@gmail.com>
commit 3b4309546b48fc167aa615a2d881a09c0a97971f upstream.
The auto_parser assumed sort() was stable, but the kernel's sort() uses
heapsort, which has never been stable. After commit 0e02ca29a563
("lib/sort: optimize heapsort with double-pop variation"), the order of
equal elements changed, causing the headset to fail to work.
Fix the issue by recording the original order of elements before
sorting and using it as a tiebreaker for equal elements in the
comparison function.
Fixes: b9030a005d58 ("ALSA: hda - Use standard sort function in hda_auto_parser.c")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 8c2fa44132e8cd1b05c77a705adb8d1f5a5daf3f upstream.
It was reported that the headphone output on Dell Venue 11 Pro 7130
becomes mono after PM resume. The cause seems to be the BIOS setting
up the codec COEF 0x0d bit 0x40 wrongly by some reason, and restoring
the original value 0x2800 fixes the problem.
This patch adds the quirk entry to perform the COEF restore.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brad Griffis <bgriffis@nvidia.com>
commit b615fbd70fce8582d92b3bdbbf3c9b80cadcfb55 upstream.
For interrupt-map entries, the DTS specification requires
that #address-cells is defined for both the child node and the
interrupt parent. For the PCIe interrupt-map entries, the parent
node ("gic") has not specified #address-cells. The existing layout
of the PCIe interrupt-map entries indicates that it assumes
that #address-cells is zero for this node.
Explicitly set #address-cells to zero for "gic" so that it complies
with the device tree specification.
NVIDIA EDK2 works around this issue by assuming #address-cells
is zero in this scenario, but that workaround is being removed and so
this update is needed or else NVIDIA EDK2 cannot successfully parse the
device tree and the board cannot boot.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Schnelle <schnelle@linux.ibm.com>
commit dc287e4c9149ab54a5003b4d4da007818b5fda3d upstream.
Since commit 25f39d3dcb48 ("s390/pci: Ignore RID for isolated VFs") PFs
which are not initially configured but in standby are considered
isolated. That is they create only a single function PCI domain. Due to
the PCI domains being created on discovery, this means that even if they
are configured later on, sibling PFs and their child VFs will not be
added to their PCI domain breaking SR-IOV expectations.
The reason the referenced commit ignored standby PFs for the creation of
multi-function PCI subhierarchies, was to work around a PCI domain
renumbering scenario on reboot. The renumbering would occur after
removing a previously in standby PF, whose domain number is used for its
configured sibling PFs and their child VFs, but which itself remained in
standby. When this is followed by a reboot, the sibling PF is used
instead to determine the PCI domain number of it and its child VFs.
In principle it is not possible to know which standby PFs will be
configured later and which may be removed. The PCI domain and root bus
are pre-requisites for hotplug slots so the decision of which functions
belong to which domain can not be postponed. With the renumbering
occurring only in rare circumstances and being generally benign, accept
it as an oddity and fix SR-IOV for initially standby PFs simply by
allowing them to create PCI domains.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Werner Sembach <wse@tuxedocomputers.com>
commit b1049f2d68693c80a576c4578d96774a68df2bad upstream.
commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets the
policy that all PCIe ports are allowed to use D3. When the system is
suspended if the port is not power manageable by the platform and won't be
used for wakeup via a PME this sets up the policy for these ports to go
into D3hot.
This policy generally makes sense from an OSPM perspective but it leads to
problems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with a
specific old BIOS. This manifests as a system hang.
On the affected Device + BIOS combination, add a quirk for the root port of
the problematic controller to ensure that these root ports are not put into
D3hot at suspend.
This patch is based on
https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.com
but with the added condition both in the documentation and in the code to
apply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and only
the affected root ports.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit 33a6938e0c3373f2d11f92d098f337668cd64fdd upstream.
The "DesignWare Cores PCI Express Controller Register Descriptions,
Version 4.60a", section "1.21.70 IATU_LWR_TARGET_ADDR_OFF_INBOUND_i",
fields LWR_TARGET_RW and LWR_TARGET_HW both state that:
"Field size depends on log2(BAR_MASK+1) in BAR match mode."
I.e. only the upper bits are writable, and the number of writable bits is
dependent on the configured BAR_MASK.
If we do not write the BAR_MASK before writing the iATU registers, we are
relying the reset value of the BAR_MASK being larger than the requested
BAR size (which is supplied in the struct pci_epf_bar which is passed to
pci_epc_set_bar()). The reset value of the BAR_MASK is SoC dependent.
Thus, if the struct pci_epf_bar requests a BAR size that is larger than the
reset value of the BAR_MASK, the iATU will try to write to read-only bits,
which will cause the iATU to end up redirecting to a physical address that
is different from the address that was intended.
Thus, we should always write the iATU registers after writing the BAR_MASK.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit 3708acbd5f169ebafe1faa519cb28adc56295546 upstream.
In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update
inbound map address") set_bar() was modified to support dynamically
changing the backing physical address of a BAR that was already configured.
This means that set_bar() can be called twice, without ever calling
clear_bar() (as calling clear_bar() would clear the BAR's PCI address
assigned by the host).
This can only be done if the new BAR size/flags does not differ from the
existing BAR configuration. Add these missing checks.
If we allow set_bar() to set e.g. a new BAR size that differs from the
existing BAR size, the new address translation range will be smaller than
the BAR size already determined by the host, which would mean that a read
past the new BAR size would pass the iATU untranslated, which could allow
the host to read memory not belonging to the new struct pci_epf_bar.
While at it, add comments which clarifies the support for dynamically
changing the physical address of a BAR. (Which was also missing.)
Fixes: 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update inbound map address")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kai Mäkisara <Kai.Makisara@kolumbus.fi>
commit 98b37881b7492ae9048ad48260cc8a6ee9eb39fd upstream.
Commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") in
v6.6 added new code to handle the Power On/Reset Unit Attention (POR UA)
sense data. This was in addition to the existing method. When this Unit
Attention is received, the driver blocks attempts to read, write and some
other operations because the reset may have rewinded the tape. Because of
the added code, also the initial POR UA resulted in blocking operations,
including those that are used to set the driver options after the device is
recognized. Also, reading and writing are refused, whereas they succeeded
before this commit.
Add code to not set pos_unknown to block operations if the POR UA is
received from the first test_ready() call after the st device has been
created. This restores the behavior before v6.6.

From: Quinn Tran <qutran@marvell.com>
commit 841df27d619ee1f5ca6473e15227b39d6136562d upstream.
Currently FCE Tracing is enabled to log additional ELS events. Instead,
user will enable or disable this feature through debugfs.
Modify existing DFS knob to allow user to enable or disable this
feature.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Biggers <ebiggers@google.com>
commit 7a0905caf5665be41094a6ceb5e9d2524de4627a upstream.
Commit 56541c7c4468 ("scsi: ufs: ufs-qcom: Switch to the new ICE API")
introduced an incorrect check of the algorithm ID into the key eviction
path, and thus qcom_ice_evict_key() is no longer ever called. Fix it.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: André Draszik <andre.draszik@linaro.org>
commit f8fb2403ddebb5eea0033d90d9daae4c88749ada upstream.
devm_blk_crypto_profile_init() registers a cleanup handler to run when
the associated (platform-) device is being released. For UFS, the
crypto private data and pointers are stored as part of the ufs_hba's
data structure 'struct ufs_hba::crypto_profile'. This structure is
allocated as part of the underlying ufshcd and therefore Scsi_host
allocation.
During driver release or during error handling in ufshcd_pltfrm_init(),
this structure is released as part of ufshcd_dealloc_host() before the
(platform-) device associated with the crypto call above is released.
Once this device is released, the crypto cleanup code will run, using
the just-released 'struct ufs_hba::crypto_profile'. This causes a
use-after-free situation:
Call trace:
kfree+0x60/0x2d8 (P)
kvfree+0x44/0x60
blk_crypto_profile_destroy_callback+0x28/0x70
devm_action_release+0x1c/0x30
release_nodes+0x6c/0x108
devres_release_all+0x98/0x100
device_unbind_cleanup+0x20/0x70
really_probe+0x218/0x2d0
In other words, the initialisation code flow is:
platform-device probe
ufshcd_pltfrm_init()
ufshcd_alloc_host()
scsi_host_alloc()
allocation of struct ufs_hba
creation of scsi-host devices
devm_blk_crypto_profile_init()
devm registration of cleanup handler using platform-device
and during error handling of ufshcd_pltfrm_init() or during driver
removal:
ufshcd_dealloc_host()
scsi_host_put()
put_device(scsi-host)
release of struct ufs_hba
put_device(platform-device)
crypto cleanup handler
To fix this use-after free, change ufshcd_alloc_host() to register a
devres action to automatically cleanup the underlying SCSI device on
ufshcd destruction, without requiring explicit calls to
ufshcd_dealloc_host(). This way:
* the crypto profile and all other ufs_hba-owned resources are
destroyed before SCSI (as they've been registered after)
* a memleak is plugged in tc-dwc-g210-pci.c remove() as a
side-effect
* EXPORT_SYMBOL_GPL(ufshcd_dealloc_host) can be removed fully as
it's not needed anymore
* no future drivers using ufshcd_alloc_host() could ever forget
adding the cleanup

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Long Li <longli@microsoft.com>
commit 87c4b5e8a6b65189abd9ea5010ab308941f964a4 upstream.
In StorVSC, payload->range.len is used to indicate if this SCSI command
carries payload. This data is allocated as part of the private driver data
by the upper layer and may get passed to lower driver uninitialized.
For example, the SCSI error handling mid layer may send TEST_UNIT_READY or
REQUEST_SENSE while reusing the buffer from a failed command. The private
data section may have stale data from the previous command.
If the SCSI command doesn't carry payload, the driver may use this value as
is for communicating with host, resulting in possible corruption.
Fix this by always initializing this value.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Igor Pylypiv <ipylypiv@google.com>
commit 9ff7c383b8ac0c482a1da7989f703406d78445c6 upstream.
Fail I/Os instead of retry to prevent user space processes from being
blocked on the I/O completion for several minutes.
Retrying I/Os during "depopulation in progress" or "depopulation restore in
progress" results in a continuous retry loop until the depopulation
completes or until the I/O retry loop is aborted due to a timeout by the
scsi_cmd_runtime_exceeced().
Depopulation is slow and can take 24+ hours to complete on 20+ TB HDDs.
Most I/Os in the depopulation retry loop end up taking several minutes
before returning the failure to user space.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
commit 8f6629c004b193d23612641c3607e785819e97ab upstream.
-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit 75b5ab134bb5 ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian Brauner <brauner@kernel.org>
commit 091ee63e36e8289f9067f659a48d497911e49d6f upstream.
Pidfs supports extensible and non-extensible ioctls. The extensible
ioctls need to check for the ioctl number itself not just the ioctl
command otherwise both backward- and forward compatibility are broken.
The pidfs ioctl handler also needs to look at the type of the ioctl
command to guard against cases where "[...] a daemon receives some
random file descriptor from a (potentially less privileged) client and
expects the FD to be of some specific type, it might call ioctl() on
this FD with some type-specific command and expect the call to fail if
the FD is of the wrong type; but due to the missing type check, the
kernel instead performs some action that userspace didn't expect."

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alice Ryhl <aliceryhl@google.com>
commit 6273a058383e05465083b535ed9469f2c8a48321 upstream.
When using Rust on the x86 architecture, we are currently using the
unstable target.json feature to specify the compilation target. Rustc is
going to change how softfloat is specified in the target.json file on
x86, thus update generate_rust_target.rs to specify softfloat using the
new option.
Note that if you enable this parameter with a compiler that does not
recognize it, then that triggers a warning but it does not break the
build.
[ For future reference, this solves the following error:
RUSTC L rust/core.o
error: Error loading target specification: target feature
`soft-float` is incompatible with the ABI but gets enabled in
target spec. Run `rustc --print target-list` for a list of
built-in targets

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhang Rui <rui.zhang@intel.com>
commit 0141978ae75bd48bac13fca6de131a5071c32011 upstream.
On some systems, the same CPU (with the same APIC ID) is assigned a
different logical CPU id after commit ec9aedb2aa1a ("x86/acpi: Ignore
invalid x2APIC entries").
This means that Linux enumerates the CPUs in a different order, which
violates ACPI specification[1] that states:
"OSPM should initialize processors in the order that they appear in
the MADT"
The problematic commit parses all LAPIC entries before any x2APIC
entries, aiming to ignore x2APIC entries with APIC ID < 255 when valid
LAPIC entries exist. However, it disrupts the CPU enumeration order on
systems where x2APIC entries precede LAPIC entries in the MADT.
Fix this problem by:
1) Parsing LAPIC entries first without registering them in the
topology to evaluate whether valid LAPIC entries exist.
2) Restoring the MADT in order parser which invokes either the LAPIC
or the X2APIC parser function depending on the entry type.
The X2APIC parser still ignores entries < 0xff in case that #1 found
valid LAPIC entries independent of their position in the MADT table.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
commit ee2ab467bddfb2d7f68d996dbab94d7b88f8eaf7 upstream.
GCC 15 changed the default C standard version to C23, which should not
have impacted the kernel because it requests the gnu11 standard via
'-std=' in the main Makefile. However, the x86 compressed boot Makefile
uses its own set of KBUILD_CFLAGS without a '-std=' value (i.e., using
the default), resulting in errors from the kernel's definitions of bool,
true, and false in stddef.h, which are reserved keywords under C23.
./include/linux/stddef.h:11:9: error: expected identifier before ‘false’
11 | false = 0,
./include/linux/types.h:35:33: error: two or more data types in declaration specifiers
35 | typedef _Bool bool;
Set '-std=gnu11' in the x86 compressed boot Makefile to resolve the
error and consistently use the same C standard version for the entire
kernel.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Romain Naour <romain.naour@skf.com>
commit c1472ec1dc4419d0bae663c1a1e6cb98dc7881ad upstream.
A bus_dma_limit was added for l3 bus by commit cfb5d65f2595
("ARM: dts: dra7: Add bus_dma_limit for L3 bus") to fix an issue
observed only with SATA on DRA7-EVM with 4GB RAM and CONFIG_ARM_LPAE
enabled.
Since kernel 5.13, the SATA issue can be reproduced again following
the SATA node move from L3 bus to L4_cfg in commit 8af15365a368
("ARM: dts: Configure interconnect target module for dra7 sata").
Fix it by adding an empty dma-ranges property to l4_cfg and
segment@100000 nodes (parent device tree node of SATA controller) to
inherit the 2GB dma ranges limit from l3 bus node.
Note: A similar fix was applied for PCIe controller by commit
90d4d3f4ea45 ("ARM: dts: dra7: Fix bus_dma_limit for PCIe").
Fixes: 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata").

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Kemnade <andreas@kemnade.info>
commit 0cfbd7805fe13406500e6a6f2aa08f198d5db4bd upstream.
Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal,
disabling SPI leads to messages like when suspending:
Powerdomain (core_pwrdm) didn't enter target state 0
and according to /sys/kernel/debug/pm_debug/count off state is not
entered. That was not connected to SPI during the discussion
of disabling SPI. See:
https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/
The reason is that SPI is per default in slave mode. Linux driver
will turn it to master per default. It slave mode, the powerdomain seems to
be kept active if active chip select input is sensed.
Fix that by explicitly disabling the SPI3 pins which used to be muxed by
the bootloader since they are available on an optionally fitted header
which would require dtb overlays anyways.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wenst@chromium.org>
commit 93a680af46436780fd64f4e856a4cfa8b393be6e upstream.
This reverts commit 377548f05bd0905db52a1d50e5b328b9b4eb049d.
Most SoC dtsi files have the display output interfaces disabled by
default, and only enabled on boards that utilize them. The MT8183
has it backwards: the display outputs are left enabled by default,
and only disabled at the board level.
Reverse the situation for the DPI output so that it follows the
normal scheme. For ease of backporting the DSI output is handled
in a separate patch.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wenst@chromium.org>
commit 26f6e91fa29a58fdc76b47f94f8f6027944a490c upstream.
Most SoC dtsi files have the display output interfaces disabled by
default, and only enabled on boards that utilize them. The MT8183
has it backwards: the display outputs are left enabled by default,
and only disabled at the board level.
Reverse the situation for the DSI output so that it follows the
normal scheme. For ease of backporting the DPI output is handled
in a separate patch.
Fixes: 88ec840270e6 ("arm64: dts: mt8183: Add dsi node")
Fixes: 19b6403f1e2a ("arm64: dts: mt8183: add mt8183 pumpkin board")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 9a27f0e1869e992e4107e2af8ec348e1a3b9d4d5 upstream.
The address space in MPSS/Modem PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x4040 was
copied from older DTS, but it grew since then.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 7a003077366946a5ed1adab6d177efb2ab59e815 upstream.
The address space in ADSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0680_0000 with length of 0x10000.
0x3000_0000, value used so far, is the main region of CDSP and was
simply copied from other/older DTS.
Correct the base address and length, which also moves the node to
different place to keep things sorted by unit address. The diff looks
big, but only the unit address and "reg" property were changed. This
should have no functional impact on Linux users, because PAS loader does
not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 3de1bf12c6bfb9a92f0803941ecae39b08470446 upstream.
The address space in CDSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x1400000 was
copied from older DTS, but it does not look accurate at all.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 472d65e7cb591c8379dd6f40561f96be73a46f0f upstream.
The address space in MPSS/Modem PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x100 was
copied from older DTS, but it grew since then.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

0x0ab0_0000, value used so far, is the SSC_QUPV3 block, so entierly
unrelated.
Correct the base address and length, which should have no functional
impact on Linux users, because PAS loader does not use this address

qup-config. Since the qup-memory path is not part of the qcom,geni-uart
bindings, just replace that path with the correct path for qup-config.

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit c9f7f341e896836c99709421a23bae5f53039aab upstream.
The address space in CDSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0b30_0000 with length of 0x10000.
0x0b00_0000, value used so far, is the main region of CDSP.
Correct the base address and length, which should have no functional
impact on Linux users, because PAS loader does not use this address
space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 918e71ba0c08c3d609ad69067854b0f675c4a253 upstream.
The address space in MPSS/Modem PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0608_0000 with length of 0x10000.
0x0600_0000, value used so far, is the main region of Modem.
Correct the base address and length, which should have no functional
impact on Linux users, because PAS loader does not use this address
space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit f9ba85566ddd5a3db8fa291aaecd70c4e55a3732 upstream.
The address space in ADSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0300_0000 with length of 0x10000. 0x1730_0000,
value used so far, was copied from downstream DTS, is in the middle of
unused space and downstream DTS describes the PIL loader, which is a bit
different interface.
Assume existing value (thus downstream DTS) is not really describing the
intended ADSP PAS region.
Correct the base address and length, which also moves the node to
different place to keep things sorted by unit address. The diff looks
big, but only the unit address and "reg" property were changed. This
should have no functional impact on Linux users, because PAS loader does
not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit f4afd8ba453b6e82245b9068868c72c831aec84e upstream.
The address space in CDSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0a30_0000 with length of 0x10000. 0x9890_0000,
value used so far, was copied from downstream DTS, is in the middle of
RAM/DDR space and downstream DTS describes the PIL loader, which is a
bit different interface. Datasheet says that one of the main CDSP
address spaces is 0x0980_0000, which is oddly similar to 0x9890_0000,
but quite different.
Assume existing value (thus downstream DTS) is not really describing the
intended CDSP PAS region.
Correct the base address and length, which also moves the node to
different place to keep things sorted by unit address. The diff looks
big, but only the unit address and "reg" property were changed. This
should have no functional impact on Linux users, because PAS loader does
not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit da1937dec9cd986e685b6a429b528a4cbc7b1603 upstream.
The address space in MPSS/Modem PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x4040 was
copied from older DTS, but it grew since then.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 13c96bee5d5e5b61a9d8d000c9bb37bb9a2a0551 upstream.
The address space in ADSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0300_0000 with length of 0x10000, which also matches
downstream DTS. 0x3000_0000, value used so far, was in datasheet is the
region of CDSP.
Correct the base address and length, which also moves the node to
different place to keep things sorted by unit address. The diff looks
big, but only the unit address and "reg" property were changed. This
should have no functional impact on Linux users, because PAS loader does
not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit a6a8f54bc2af555738322783ba1e990c2ae7f443 upstream.
The address space in ADSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB): 0x0680_0000 with length of 0x10000.
0x3000_0000, value used so far, is the main region of CDSP. Downstream
DTS uses 0x0300_0000, which is oddly similar to 0x3000_0000, yet quite
different and points to unused area.
Correct the base address and length, which also moves the node to
different place to keep things sorted by unit address. The diff looks
big, but only the unit address and "reg" property were changed. This
should have no functional impact on Linux users, because PAS loader does
not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit 6b2570e1e43e4acd0fcb98c6489736fe1c67b222 upstream.
The address space in CDSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x1400000 was
copied from older DTS, but it does not look accurate at all.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit aca0053f051625a224c2e802a0e88755770819e4 upstream.
The address space in CDSP PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x1400000 was
copied from older DTS, but it does not look accurate at all.
This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

commit d4fa87daf3dd39d6bd4b69613e22bfb43c737831 upstream.

remoteproc node should point to the QDSP PUB address space

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
commit b8591df49cde459e3b84cdc0517d7bf92053d244 upstream.
SM8550 lists two interconnects for the display subsystem, mdp0-mem
(between MDP and LLCC) and mdp1-mem (between LLCC and EBI, memory).
The second interconnect is a misuse. mdpN-mem paths should be used for
several outboud MDP interconnects rather than the path between LLCC and
memory. This kind of misuse can result in bandwidth underflows, possibly
degrading picture quality as the required memory bandwidth is divided
between all mdpN-mem paths (and LLCC-EBI should not be a part of such
division).
Drop the second path and use direct MDP-EBI path for mdp0-mem until we
support separate MDP-LLCC and LLCC-EBI paths.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Biggers <ebiggers@google.com>
commit 49b9258b05b97c6464e1964b6a2fddb3ddb65d17 upstream.
As QCE is an order of magnitude slower than the ARMv8 Crypto Extensions
on the CPU, and is also less well tested, give it a lower priority.
Previously the QCE SHA algorithms had higher priority than the ARMv8 CE
equivalents, and the ciphers such as AES-XTS had the same priority which
meant the QCE versions were chosen if they happened to be loaded later.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sumit Gupta <sumitg@nvidia.com>
commit 604120fd9e9df50ee0e803d3c6e77a1f45d2c58e upstream.
The compatible string for the Tegra DCE fabric is currently defined as
'nvidia,tegra234-sce-fabric' but this is incorrect because this is the
compatible string for SCE fabric. Update the compatible for the DCE
fabric to correct the compatible string.
This compatible needs to be correct in order for the interconnect
to catch things such as improper data accesses.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sumit Gupta <sumitg@nvidia.com>
commit a5e6fc0a10fe280989f1367a3b4f8047c7d00ea6 upstream.
Access to safety cluster engine (SCE) fabric registers was blocked
by firewall after the introduction of Functional Safety Island in
Tegra234. After that, any access by software to SCE registers is
correctly resulting in the internal bus error. However, when CPUs
try accessing the SCE-fabric registers to print error info,
another firewall error occurs as the fabric registers are also
firewall protected. This results in a second error to be printed.
Disable the SCE fabric node to avoid printing the misleading error.
The first error info will be printed by the interrupt from the
fabric causing the actual access.

lsm: replace indirect LSM hook calls with static calls
After more analysis it seems that we don't fully implement the static calls
and jump tables yet. Additionally the functions which mark kernel memory
read-only or read-write-executable needs to be further enhanced to be able to
fully support static calls.
Enabling CONFIG_SECURITY_YAMA=y was one possibility to trigger the issue,
although YAMA isn't the reason for the fault.
As a temporary solution disable JUMP_LABEL functionality to
avoid the crashes.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Conor Dooley <conor.dooley@microchip.com>
commit 752b6e3af374460a2de18f0c10bfa06bf844dbe8 upstream.
In mchp_core_pwm_apply_locked(), if hw_period_steps is equal to its max,
an error is reported and .apply fails. The max value is actually a
permitted value however, and so this check can fail where multiple
channels are enabled.
For example, the first channel to be configured requests a period that
sets hw_period_steps to the maximum value, and when a second channel
is enabled the driver reads hw_period_steps back from the hardware and
finds it to be the maximum possible value, triggering the warning on a
permitted value. The value to be avoided is 255 (PERIOD_STEPS_MAX + 1),
as that will produce undesired behaviour, so test for greater than,
rather than equal to.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Hellwig <hch@lst.de>
commit f5f0ed89f13e3e5246404a322ee85169a226bfb5 upstream.
The XFS_IOC_EXCHANGE_RANGE ioctl with the XFS_EXCHANGE_RANGE_TO_EOF flag
operates on a range bounded by the end of the file. This means the
actual amount of blocks exchanged is derived from the inode size, which
is only stable with the IOLOCK (i_rwsem) held. Do that, it currently
calls remap_verify_area from inside the sb write protection which nests
outside the IOLOCK. But this makes fsnotify_file_area_perm which is
called from remap_verify_area unhappy when the kernel is built with
lockdep and the recently added CONFIG_FANOTIFY_ACCESS_PERMISSIONS
option.
Fix this by always calling remap_verify_area before taking the write
protection, and passing a 0 size to remap_verify_area similar to
the FICLONE/FICLONERANGE ioctls when they are asked to clone until
the file end.
(Note: the size argument gets passed to fsnotify_file_area_perm, but
then isn't actually used there).

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wentao Liang <vulab@iscas.ac.cn>
commit 26b63bee2f6e711c5a169997fd126fddcfb90848 upstream.
In xfs_inactive(), xfs_reflink_cancel_cow_range() is called
without error handling, risking unnoticed failures and
inconsistent behavior compared to other parts of the code.
Fix this issue by adding an error handling for the
xfs_reflink_cancel_cow_range(), improving code robustness.
Fixes: 6231848c3aa5 ("xfs: check for cow blocks before trying to clear them")

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com>
commit f2bc2afe34c107a02ce829a4039e85514feafe55 upstream.
pm_runtime_resume_and_get() sets dev->power.runtime_error that causes
all subsequent pm_runtime_get_sync() calls to fail.
Clear the runtime_error using pm_runtime_set_suspended(), so the driver
doesn't have to be reloaded to recover when the NPU fails to boot during
runtime resume.

commit 41a2d8286c905614f29007f1bc8e652d54654b82 upstream.
Disable runtime PM for the duration of reset/recovery so it is possible
to set the correct runtime PM state depending on the outcome of the
`ivpu_resume()`. Don’t suspend or reset the HW if the NPU is suspended
when the reset/recovery is requested. Also, move common reset/recovery
code to separate functions for better code readability.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aubrey Li <aubrey.li@linux.intel.com>
commit 7f5704b6a143b8eca640cba820968e798d065e91 upstream.
Commit 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM
handler and context") added unnecessary strict handler address checks,
causing the PRM module to fail in translating memory error addresses.
Both static data buffer address and ACPI parameter buffer address may
be NULL if they are not needed, as described in section 4.1.2 PRM Handler
Information Structure of Platform Runtime Mechanism specification [1].
Here are two examples from real hardware:

events because RSI maps to the 'order' parameter of __alloc_pages_noprof().
Address the bug by moving from devm_kmalloc() to devm_add_action() and
kvmalloc() and devm_add_action().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gabriele Monaco <gmonaco@redhat.com>
commit 8259cb14a70680553d5e82d65d1302fe589e9b39 upstream.
RV per-task monitors are implemented through a monitor structure
available for each task_struct. This structure is reset every time the
monitor is (re-)started, to avoid inconsistencies if the monitor was
activated previously.
To do so, we reset the monitor on all threads using the macro
for_each_process_thread. However, this macro excludes the idle tasks on
each CPU. Idle tasks could be considered tasks on their own right and it
should be up to the model whether to ignore them or not.
Reset monitors also on the idle tasks for each present CPU whenever we
reset all per-task monitors.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frederic Weisbecker <frederic@kernel.org>
commit 53dac345395c0d2493cbc2f4c85fe38aef5b63f5 upstream.
hrtimers are migrated away from the dying CPU to any online target at
the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers
handling tasks involved in the CPU hotplug forward progress.
However wakeups can still be performed by the outgoing CPU after
CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being
armed. Depending on several considerations (crystal ball power management
based election, earliest timer already enqueued, timer migration enabled or
not), the target may eventually be the current CPU even if offline. If that
happens, the timer is eventually ignored.
The most notable example is RCU which had to deal with each and every of
those wake-ups by deferring them to an online CPU, along with related
workarounds:
_ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying)
_ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU)
_ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq)
The problem isn't confined to RCU though as the stop machine kthread
(which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end
of its work through cpu_stop_signal_done() and performs a wake up that
eventually arms the deadline server timer:
WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0
CPU: 94 UID: 0 PID: 588 Comm: migration/94 Not tainted

cpu_stopper_thread
Instead of providing yet another bandaid to work around the situation, fix
it in the hrtimers infrastructure instead: always migrate away a timer to
an online target whenever it is enqueued from an offline CPU.
This will also allow to revert all the above RCU disgraceful hacks.

------------------
From: Easwar Hariharan <eahariha@linux.microsoft.com>
commit bb2784d9ab49587ba4fbff37a319fff2924db289 upstream.
While converting users of msecs_to_jiffies(), lkp reported that some range
checks would always be true because of the mismatch between the implied int
value of secs_to_jiffies() vs the unsigned long return value of the
msecs_to_jiffies() calls it was replacing.
Fix this by casting the secs_to_jiffies() input value to unsigned long.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolin Chen <nicolinc@nvidia.com>
commit e721f619e3ec9bae08bf419c3944cf1e6966c821 upstream.
The iommu_hwpt_pgfault is used to report IO page fault data to userspace,
but iommufd_fault_fops_read was never zeroing its padding. This leaks the
content of the kernel stack memory to userspace.
Also, the iommufd uAPI requires explicit padding and use of __aligned_u64
to ensure ABI compatibility's with 32 bit.
pahole result, before:
struct iommu_hwpt_pgfault {
__u32 flags; /* 0 4 */
__u32 dev_id; /* 4 4 */
__u32 pasid; /* 8 4 */

/* size: 40, cachelines: 1, members: 8 */
/* sum members: 36, holes: 1, sum holes: 4 */
/* last cacheline: 40 bytes */
};
pahole result, after:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marco Elver <elver@google.com>
commit e64f81946adf68cd75e2207dd9a51668348a4af8 upstream.
On NUMA systems, __GFP_THISNODE indicates that an allocation _must_ be on
a particular node, and failure to allocate on the desired node will result
in a failed allocation.
Skip __GFP_THISNODE allocations if we are running on a NUMA system, since
KFENCE can't guarantee which node its pool pages are allocated on.

commit da73efa8e675a2b58f1c7ae61201acfe57714bf7 upstream.
ccs_data_parse() releases the allocated in-memory data structure when the
parser fails, but it does not clean up parsed metadata that is there to
help access the actual data. Do that, in order to return the data
structure in a sane state.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Xu <peterx@redhat.com>
commit 58db7c5fbe7daa42098d4965133a864f98ba90ba upstream.
Patch series "mm/hugetlb: Refactor hugetlb allocation resv accounting",
v2.
This is a follow up on Ackerley's series here as replacement:
https://lore.kernel.org/r/cover.1728684491.git.ackerleytng@google.com
The goal of this series is to cleanup hugetlb resv accounting, especially
during folio allocation, to decouple a few things:
- Hugetlb folios v.s. Hugetlbfs: IOW, the hope is in the future hugetlb
folios can be allocated completely without hugetlbfs.
- Decouple VMA v.s. hugetlb folio allocations: allocating a hugetlb folio
should not always require a hugetlbfs VMA. For example, either it got
allocated from the inode level (see hugetlbfs_fallocate() where it used
a pesudo VMA for allocation), or it can be allocated by other kernel
subsystems.
It paves way for other users to allocate hugetlb folios out of either
system reservations, or subpools (instead of hugetlbfs, as a file system).
For longer term, this prepares hugetlb as a separate concept versus
hugetlbfs, so that hugetlb folios can be allocated by not only hugetlbfs
and other things.
Tests I've done:
- I had a reproducer in patch 1 for the bug I found, this will start to
work after patch 1 or the whole set applied.
- Hugetlb regression tests (on x86_64 2MBs), includes:
- All vmtests on hugetlbfs
- libhugetlbfs test suite (which may fail some tests, but no new failures
will be introduced by this series, so all such failures happen before
this series so shouldn't be relevant).
This patch (of 7):
Since commit 04f2cbe35699 ("hugetlb: guarantee that COW faults for a
process that called mmap(MAP_PRIVATE) on hugetlbfs will succeed"),
avoid_reserve was introduced for a special case of CoW on hugetlb private
mappings, and only if the owner VMA is trying to allocate yet another
hugetlb folio that is not reserved within the private vma reserved map.
Later on, in commit d85f69b0b533 ("mm/hugetlb: alloc_huge_page handle
areas hole punched by fallocate"), alloc_huge_page() enforced to not
consume any global reservation as long as avoid_reserve=true. This
operation doesn't look correct, because even if it will enforce the
allocation to not use global reservation at all, it will still try to take
one reservation from the spool (if the subpool existed). Then since the
spool reserved pages take from global reservation, it'll also take one
reservation globally.
Logically it can cause global reservation to go wrong.
I wrote a reproducer below, trigger this special path, and every run of
such program will cause global reservation count to increment by one, until
it hits the number of free pages:
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <stdio.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/mman.h>
#define MSIZE (2UL << 20)
int main(int argc, char *argv[])
{
const char *path;
int *buf;
int fd, ret;
pid_t child;
if (argc < 2) {
printf("usage: %s <hugetlb_file>\n", argv[0]);
return -1;
}
path = argv[1];
fd = open(path, O_RDWR | O_CREAT, 0666);
if (fd < 0) {
perror("open failed");
return -1;
}
ret = fallocate(fd, 0, 0, MSIZE);
if (ret != 0) {
perror("fallocate");
return -1;
}
buf = mmap(NULL, MSIZE, PROT_READ|PROT_WRITE,
MAP_PRIVATE, fd, 0);
if (buf == MAP_FAILED) {
perror("mmap() failed");
return -1;
}
/* Allocate a page */
*buf = 1;
child = fork();
if (child == 0) {
/* child doesn't need to do anything */
exit(0);
}
/* Trigger CoW from owner */
*buf = 2;
munmap(buf, MSIZE);
close(fd);
unlink(path);
return 0;
}
It can only reproduce with a sub-mount when there're reserved pages on the
spool, like:
# sysctl vm.nr_hugepages=128
# mkdir ./hugetlb-pool
# mount -t hugetlbfs -o min_size=8M,pagesize=2M none ./hugetlb-pool
Then run the reproducer on the mountpoint:
# ./reproducer ./hugetlb-pool/test
Fix it by taking the reservation from spool if available. In general,
avoid_reserve is IMHO more about "avoid vma resv map", not spool's.
I copied stable, however I have no intention for backporting if it's not a
clean cherry-pick, because private hugetlb mapping, and then fork() on top
is too rare to hit.

The bme680_read_temp() function takes a pointer to s16 but we're passing
an int pointer to it. This will not work on big endian systems and it
also means that the other 16 bits are uninitialized.

commit 1e758b613212b6964518a67939535910b5aee831 upstream.
Fix ad3541/2r voltage ranges to be as per ad3542r datasheet,
rev. C, table 38 (page 57).
The wrong ad354xr ranges was generating erroneous Vpp output.
In more details:
- fix wrong number of ranges, they are 5 ranges, not 6,
- remove non-existent 0-3V range,
- adjust order, since ad3552r_find_range() get a wrong index,
producing a wrong Vpp as output.
Retested all the ranges on real hardware, EVALAD3542RFMCZ:
adi,output-range-microvolt (fdt):

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Angelo Dureghello <adureghello@baylibre.com>
commit 012b8276f08a67b9f2e2fd0f35363ae4a75e5267 upstream.
Clear reset status flag, to keep error status register
clean after reset (ad3552r manual, rev B table 38).
Reset error flag was left to 1, so debugging registers, the
"Error Status Register" was dirty (0x01). It is important
to clear this bit, so if there is any reset event over normal
working mode, it is possible to detect it.

------------------
From: Javier Carrasco <javier.carrasco.cruz@gmail.com>
commit ab09c6cfe01b317f515bcd944668697241a54b9d upstream.
The channel index is off by one unit if AS73211_SCAN_MASK_ALL is not
set (optimized path for color channel readings), and it must be shifted
instead of leaving an empty channel for the temperature when it is off.
Once the channel index is fixed, the uninitialized channel must be set
to zero to avoid pushing uninitialized data.
Add available_scan_masks for all channels and only-color channels to let
the IIO core demux and repack the enabled channels.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolin Chen <nicolinc@nvidia.com>
commit e94dc6ddda8dd3770879a132d577accd2cce25f9 upstream.
The hardware limitation "max=19" actually comes from SMMU Command Queue.
So, it'd be more natural for tegra241-cmdqv driver to read it out rather
than hardcoding it itself.
This is not an issue yet for a kernel on a baremetal system, but a guest
kernel setting the queue base/size in form of IPA/gPA might result in a
noncontiguous queue in the physical address space, if underlying physical
pages backing up the guest RAM aren't contiguous entirely: e.g. 2MB-page
backed guest RAM cannot guarantee a contiguous queue if it is 8MB (capped
to VCMDQ_LOG2SIZE_MAX=19). This might lead to command errors when HW does
linear-read from a noncontiguous queue memory.
Adding this extra IDR1.CMDQS cap (in the guest kernel) allows VMM to set
SMMU's IDR1.CMDQS=17 for the case mentioned above, so a guest-level queue
will be capped to maximum 2MB, ensuring a contiguous queue memory.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolin Chen <nicolinc@nvidia.com>
commit 3d49020a327cd7d069059317c11df24e407ccfa3 upstream.
The fault->mutex serializes the fault read()/write() fops and the
iommufd_fault_auto_response_faults(), mainly for fault->response. Also, it
was conveniently used to fence the fault->deliver in poll() fop and
iommufd_fault_iopf_handler().
However, copy_from/to_user() may sleep if pagefaults are enabled. Thus,
they could take a long time to wait for user pages to swap in, blocking
iommufd_fault_iopf_handler() and its caller that is typically a shared IRQ
handler of an IOMMU driver, resulting in a potential global DOS.
Instead of reusing the mutex to protect the fault->deliver list, add a
separate spinlock, nested under the mutex, to do the job.
iommufd_fault_iopf_handler() would no longer be blocked by
copy_from/to_user().
Add a free_list in iommufd_auto_response_faults(), so the spinlock can
simply fence a fast list_for_each_entry_safe routine.
Provide two deliver list helpers for iommufd_fault_fops_read() to use:
- Fetch the first iopf_group out of the fault->deliver list
- Restore an iopf_group back to the head of the fault->deliver list
Lastly, move the mutex closer to the response in the fault structure,
and update its kdoc accordingly.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
commit eca836dfd8386b32f1aae60f8e323218ac6a0b75 upstream.
If tensor_set_bits_atomic() is called with a mask of 0 the function will
just iterate over its bit, not perform any updates and return stack
value of 'ret'.
Also reported by smatch:
drivers/soc/samsung/exynos-pmu.c:129 tensor_set_bits_atomic() error: uninitialized symbol 'ret'.

commit 35d8bc131de0f0f280f0db42499512d79f05f456 upstream.
The Last Level Cache is split into many slices, each one of which can
be toggled on or off.
Only certain slices are recommended to be turned on unconditionally,
in order to reach optimal performance/latency/power levels.
Enable WRCACHE on X1 at boot, in accordance with internal
recommendations.
No significant performance difference is expected.

------------------
From: Lubomir Rintel <lkundrak@v3.sk>
commit fbb5298bf1a7b71723cd2bb193642429ceb0fb84 upstream.
In commit 4af65141e38e ("media: marvell: cafe: Register V4L2 device
earlier"), a call to v4l2_device_register() was moved away from
mccic_register() into its caller, marvell/cafe's cafe_pci_probe().
This is not the only caller though -- there's also marvell/mmp.
Add v4l2_device_register() into mmpcam_probe() to unbreak the MMP camera
driver, in a fashion analogous to what's been done to the Cafe driver.
Same for the teardown path.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cosmin Tanislav <demonsingur@gmail.com>
commit fb2bd86270cd0ad004f4c614ba4f8c63a5720e25 upstream.
When creating links from a subdev to a sink, the current logic tries to
iterate over the endpoints of dev's fwnode.
This might not be correct when the subdev uses a different fwnode
compared to the dev's fwnode.
If, when registering, the subdev's fwnode is not set, the code inside
v4l2_async_register_subdev will set it to the dev's fwnode.
To fix this, just use the subdev's fwnode.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhen Lei <thunder.leizhen@huawei.com>
commit c4b7779abc6633677e6edb79e2809f4f61fde157 upstream.
When function of_find_device_by_node() fails, it returns NULL instead of
an error code. So the corresponding error check logic should be modified
to check whether the return value is NULL and set the error code to be
returned as -ENODEV.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Naushir Patuck <naush@raspberrypi.com>
commit 57d10bcac67707caaa542e09dee86e13ea85defc upstream.
Add a 2-5ms delay when coming out of standby and before reading the
sensor info register durning probe, as instructed by the datasheet. This
standby delay is already present when the sensor starts streaming.
During a cold-boot, reading the IMX296_SENSOR_INFO register would often
return a value of 0x0000, if this delay is not present before.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sergey Senozhatsky <senozhatsky@chromium.org>
commit df4ff47448fe0d392b29868e8398e3b0e587514d upstream.
This partially reverts commit that made hfi_session_destroy()
the first step of vdec/venc close(). The reason being is a
regression report when, supposedly, encode/decoder is closed
with still active streaming (no ->stop_streaming() call before
close()) and pending pkts, so isr_thread cannot find instance
and fails to process those pending pkts. This was the idea
behind the original patch - make it impossible to use instance
under destruction, because this is racy, but apparently there
are uses cases that depend on that unsafe pattern. Return to
the old (unsafe) behaviour for the time being (until a better
fix is found).

commit 82b696750f0b60e7513082a10ad42786854f59f8 upstream.
The length field of the CCS static data blocks was mishandled, leading to
wrong interpretation of the length header for blocks that are 16 kiB in
size. Such large blocks are very, very rare and so this wasn't found
earlier.
As the length is used as part of input validation, the issue has no
security implications.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
commit 60b45ece41c5632a3a3274115a401cb244180646 upstream.
The ub913 and ub953 drivers call fwnode_handle_put(priv->sd.fwnode) as
part of their remove process, and if the driver is removed multiple
times, eventually leads to put "overflow", possibly causing memory
corruption or crash.
The fwnode_handle_put() is a leftover from commit 905f88ccebb1 ("media:
i2c: ds90ub9x3: Fix sub-device matching"), which changed the code
related to the sd.fwnode, but missed removing these fwnode_handle_put()
calls.

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
commit 698cf6df87ffa83f259703e7443c15a4c5ceae86 upstream.
UB9702 doesn't have the registers for SP and EQ. Adjust the code in
ub960_rxport_wait_locks() to not use those registers for UB9702. As
these values are only used for a debug print here, there's no functional
change.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
commit 5dbbd0609b83f6eb72c005e2e5979d0cd25243c8 upstream.
The driver uses a static CSI-2 virtual channel mapping where all virtual
channels from an RX port are mapped to a virtual channel number matching
the RX port number.
The UB960 and UB9702 have different registers for the purpose, and the
UB9702 version is not correct. Each of the VC_ID_MAP registers do not
contain a single mapping, as the driver currently thinks, but two.
This can cause received VCs other than 0 to be mapped in a wrong way.
Fix this by writing both mappings to each register.

commit 42d0ec194aa12e9b97f09a94fe565ba2e5f631a2 upstream.
UB9702 does not have SP and EQ registers, but the driver uses them in
log_status(). Fix this by separating the SP and EQ related log_status()
work into a separate function (for clarity) and calling that function
only for UB960.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit a9ea1a3d88b7947ce8cadb2afceee7a54872bbc5 upstream.
We used the wrong device for the device managed functions. We used the
usb device, when we should be using the interface device.
If we unbind the driver from the usb interface, the cleanup functions
are never called. In our case, the IRQ is never disabled.
If an IRQ is triggered, it will try to access memory sections that are
already free, causing an OOPS.
We cannot use the function devm_request_threaded_irq here. The devm_*
clean functions may be called after the main structure is released by
uvc_delete.
Luckily this bug has small impact, as it is only affected by devices
with gpio units and the user has to unbind the device, a disconnect will
not trigger this error.

This is because we keep using the same variable all the time and we do
not reset its original value.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit f00ee2ca8da25ebccb8e19956d853c9055e2c8d0 upstream.
Some cameras, like the ELMO MX-P3, do not return all the bytes
requested from a control if it can fit in less bytes.
Eg: Returning 0xab instead of 0x00ab.
usb 3-9: Failed to query (GET_DEF) UVC control 3 on unit 2: 1 (exp. 2).
Extend the returned value from the camera and return it.

commit d9fecd096f67a4469536e040a8a10bbfb665918b upstream.
Now we keep a reference to the active fh for any call to uvc_ctrl_set,
regardless if it is an actual set or if it is a just a try or if the
device refused the operation.
We should only keep the file handle if the device actually accepted
applying the operation.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricardo Ribalda <ribalda@chromium.org>
commit 221cd51efe4565501a3dbf04cc011b537dcce7fb upstream.
When an async control is written, we copy a pointer to the file handle
that started the operation. That pointer will be used when the device is
done. Which could be anytime in the future.
If the user closes that file descriptor, its structure will be freed,
and there will be one dangling pointer per pending async control, that
the driver will try to use.
Clean all the dangling pointers during release().
To avoid adding a performance penalty in the most common case (no async
operation), a counter has been introduced with some logic to make sure
that it is properly handled.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Catalin Marinas <catalin.marinas@arm.com>
commit 488b5b9eca68497b533ced059be5eff19578bbca upstream.
Memblock allocations are registered by kmemleak separately, based on their
physical address. During the scanning stage, it checks whether an object
is within the min_low_pfn and max_low_pfn boundaries and ignores it
otherwise.
With the recent addition of __percpu pointer leak detection (commit
6c99d4eb7c5e ("kmemleak: enable tracking for percpu pointers")), kmemleak
started reporting leaks in setup_zone_pageset() and
setup_per_cpu_pageset(). These were caused by the node_data[0] object
(initialised in alloc_node_data()) ending on the PFN_PHYS(max_low_pfn)
boundary. The non-strict upper boundary check introduced by commit
84c326299191 ("mm: kmemleak: check physical address when scan") causes the
pg_data_t object to be ignored (not scanned) and the __percpu pointers it
contains to be reported as leaks.
Make the max_low_pfn upper boundary check strict when deciding whether to
ignore a physical address object and not scan it.

From: Zhaoyang Huang <zhaoyang.huang@unisoc.com>
commit 1aaf8c122918aa8897605a9aa1e8ed6600d6f930 upstream.
We can run into an infinite loop in __get_longterm_locked() when
collect_longterm_unpinnable_folios() finds only folios that are isolated
from the LRU or were never added to the LRU. This can happen when all
folios to be pinned are never added to the LRU, for example when
vm_ops->fault allocated pages using cma_alloc() and never added them to
the LRU.
Fix it by simply taking a look at the list in the single caller, to see if
anything was added.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li Zhijian <lizhijian@fujitsu.com>
commit a479b078fddb0ad7f9e3c6da22d9cf8f2b5c7799 upstream.
In shrink_folio_list(), demote_folio_list() can be called 2 times.
Currently stat->nr_demoted will only store the last nr_demoted( the later
nr_demoted is always zero, the former nr_demoted will get lost), as a
result number of demoted pages is not accurate.
Accumulate the nr_demoted count across multiple calls to
demote_folio_list(), ensuring accurate reporting of demotion statistics.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ritesh Harjani (IBM) <ritesh.list@gmail.com>
commit 76e961157e078bc5d3cd2df08317e00b00a829eb upstream.
gather_bootmem_prealloc() assumes the start nid as 0 and size as
num_node_state(N_MEMORY). That means in case if memory attached numa
nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail
to scan few of these nodes.
Since memory attached numa nodes can be interleaved in any fashion, hence
ensure that the current code checks for all numa node ids
(.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that
it can distributes all nr_node_ids among the these many no. threads.
e.g. qemu cmdline
========================
numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20"

commit d1366e74342e75555af2648a2964deb2d5c92200 upstream.
syzkaller reported a UBSAN shift-out-of-bounds warning of (1UL << order)
in isolate_freepages_block(). The bogus compound_order can be any value
because it is union with flags. Add back the MAX_PAGE_ORDER check to fix
the warning.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit 6e74e53b34b6dec5a50e1404e2680852ec6768d2 upstream.
reveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_len
set to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set to
ATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() to
write outside the allocated buffer, overwriting random memory.
While a ATA device is supposed to abort a ATA_NOP command, there does seem
to be a bug either in libata-sff or QEMU, where either this status is not
set, or the status is cleared before read by ata_sff_hsm_move().
Anyway, that is most likely a separate bug.
Looking at __atapi_pio_bytes(), it already has a safety check to ensure
that __atapi_pio_bytes() cannot write outside the allocated buffer.
Add a similar check to ata_pio_sector(), such that also ata_pio_sector()
cannot write outside the allocated buffer.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Eichenberger <eichest@gmail.com>
commit 987f379b54091cc1b1db986bde71cee1081350b3 upstream.
mvebu_icu_translate() incorrectly casts irq_domain::host_data directly to
mvebu_icu_msi_data. However, host_data actually points to a structure of
type msi_domain_info.
This incorrect cast causes issues such as the thermal sensors of the
CP110 platform malfunctioning. Specifically, the translation of the SEI
interrupt to IRQ_TYPE_EDGE_RISING fails, preventing proper interrupt
handling. The following error was observed:
genirq: Setting trigger mode 4 for irq 85 failed (irq_chip_set_type_parent+0x0/0x34)
armada_thermal f2400000.system-controller:thermal-sensor@70: Cannot request threaded IRQ 85
Resolve the issue by first casting host_data to msi_domain_info and then
accessing mvebu_icu_msi_data through msi_domain_info::chip_data.

If qce_check_version() fails, we should jump to err_dma as we already
called qce_dma_request() a couple lines before.

commit e80cf84b608725303113d6fe98bb727bf7b7a40d upstream.
If we encounter an error when registering alorithms with the crypto
framework, we just bail out and don't unregister the ones we
successfully registered in prior iterations of the loop.
Add code that goes back over the algos and unregisters them before
returning an error from qce_register_algs().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antoine Viallon <antoine@lesviallon.fr>
commit 3b7d93db450e9d8ead80d75e2a303248f1528c35 upstream.
We now free the temporary target path substring allocation on every
possible branch, instead of omitting the default branch. In some
cases, a memory leak occured, which could rapidly crash the system
(depending on how many file accesses were attempted).
This was detected in production because it caused a continuous memory
growth, eventually triggering kernel OOM and completely hard-locking
the kernel.
Relevant kmemleak stacktrace:

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jennifer Berringer <jberring@redhat.com>
commit 31507fc2ad36e0071751a710449db19c85d82a7f upstream.
When __nvmem_cell_entry_write() is called for an nvmem cell that does
not need bit shifting, it requires that the len parameter exactly
matches the nvmem cell size. However, when the nvmem cell has a nonzero
bit_offset, it was skipping this check.
Accepting values of len larger than the cell size results in
nvmem_cell_prepare_write_buffer() trying to write past the end of a heap
buffer that it allocates. Add a check to avoid that problem and instead
return -EINVAL when len doesn't match the number of bits expected by the
nvmem cell when bit_offset is nonzero.
This check uses cell->nbits in order to allow providing the smaller size
to cells that are shifted into another byte by bit_offset. For example,
a cell with nbits=8 and nonzero bit_offset would have bytes=2 but should
accept a 1-byte write here, although no current callers depend on this.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sascha Hauer <s.hauer@pengutronix.de>
commit 391b06ecb63e6eacd054582cb4eb738dfbf5eb77 upstream.
According to the i.MX93 Fusemap the two MAC addresses are stored in
words 315 to 317 like this:
315 MAC1_ADDR_31_0[31:0]
316 MAC1_ADDR_47_32[47:32]
MAC2_ADDR_15_0[15:0]
317 MAC2_ADDR_47_16[31:0]
This means the MAC addresses are stored in reverse byte order. We have
to swap the bytes before passing them to the upper layers. The storage
format is consistent to the one used on i.MX6 using imx-ocotp driver
which does the same byte swapping as introduced here.
With this patch the MAC address on my i.MX93 TQ board correctly reads as
00:d0:93:6b:27:b8 instead of b8:27:6b:93:d0:00.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sascha Hauer <s.hauer@pengutronix.de>
commit 3c9e2cb6cecf65f7501004038c5d1ed85fb7db84 upstream.
In imx_ocotp_reg_read() the offset comes in as bytes and not as words.
This means we have to divide offset by 4 to get to the correct word
offset.
Also the incoming offset might not be word aligned. In order to read
from the OCOTP the driver aligns down the previous word boundary and
reads from there. This means we have to skip this alignment offset from
the temporary buffer when copying the data to the output buffer.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sascha Hauer <s.hauer@pengutronix.de>
commit 1b2cb4d0b5b6a9d9fe78470704309ec75f8a1c3a upstream.
The ELE hardware internally has a word length of 4. However, among other
things we store MAC addresses in the ELE OCOTP. With a length of 6 bytes
these are naturally unaligned to the word length. Therefore we must
support unaligned reads in reg_read() and indeed it works properly when
reg_read() is called via nvmem_reg_read(). Setting the word size to 4
has the only visible effect that doing unaligned reads from userspace
via bin_attr_nvmem_read() do not work because they are rejected by that
function.
Given that we have to abstract from word accesses to byte accesses in
the driver, set the word size to 1. This allows bytewise accesses from
userspace to be able to test what the driver has to support anyway.

------------------
From: Jens Axboe <axboe@kernel.dk>
commit 8c8492ca64e79c6e0f433e8c9d2bcbd039ef83d0 upstream.
If a socket is shutdown before the connection completes, POLLERR is set
in the poll mask. However, connect ignores this as it doesn't know, and
attempts the connection again. This may lead to a bogus -ETIMEDOUT
result, where it should have noticed the POLLERR and just returned
-ECONNRESET instead.
Have the poll logic check for whether or not POLLERR is set in the mask,
and if so, mark the request as failed. Then connect can appropriately
fail the request rather than retry it.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthieu Baerts (NGI0) <matttbe@kernel.org>
commit 5368a67307b3b2c347dc8965ac55b888be665934 upstream.
The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE
by closing the connection with unread bytes in the receive queue.
The xdisconnect() helper was used to stop the connection, but it does
more than that: it will shut it down, then wait before reconnecting to
the same address. This causes the mptcp_join's "fastclose test" to fail
all the time.
This failure is due to a recent change, with commit 218cc166321f
("selftests: mptcp: avoid spurious errors on disconnect"), but that went
unnoticed because the test is currently ignored. The recent modification
only shown an existing issue: xdisconnect() doesn't need to be used
here, only the shutdown() part is needed.

in -EAGAIN have ff_layout_pg_init_read() retry it after sleeping.
If "softerr" mount is used, use 'io_maxretrans' to limit the number of

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox (Oracle) <willy@infradead.org>
commit 2b4c2094da6d84e69b843dd3317902e977bf64bd upstream.
Patch series "Convert ocfs2 to use folios".
Mark did a conversion of ocfs2 to use folios and sent it to me as a
giant patch for review ;-)
So I've redone it as individual patches, and credited Mark for the patches
where his code is substantially the same. It's not a bad way to do it;
his patch had some bugs and my patches had some bugs. Hopefully all our
bugs were different from each other. And hopefully Mark likes all the
changes I made to his code!
This patch (of 23):

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>
commit 6438ef381c183444f7f9d1de18f22661cba1e946 upstream.
Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result
by being prepared to go through potentially maxblocks == INT_MAX blocks,
the value in n may experience an overflow caused by left shift of blkbits.
While it is extremely unlikely to occur, play it safe and cast right hand
expression to wider type to mitigate the issue.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dragan Simic <dsimic@manjaro.org>
commit 90190ba1c3b11687e2c251fda1f5d9893b4bab17 upstream.
Having the NFS_FSCACHE option depend on the NETFS_SUPPORT options makes
selecting NFS_FSCACHE impossible unless another option that additionally
selects NETFS_SUPPORT is already selected.
As a result, for example, being able to reach and select the NFS_FSCACHE
option requires the CEPH_FS or CIFS option to be selected beforehand, which
obviously doesn't make much sense.
Let's correct this by making the NFS_FSCACHE option actually select the
NETFS_SUPPORT option, instead of depending on it.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <chuck.lever@oracle.com>
commit ef3675b45bcb6c17cabbbde620c6cea52ffb21ac upstream.
J. David reports an odd corruption of a READDIR reply sent to a
FreeBSD client.
xdr_reserve_space() has to do a special trick when the @nbytes value
requests more space than there is in the current page of the XDR
buffer.
In that case, xdr_reserve_space() returns a pointer to the start of
the next page, and then the next call to xdr_reserve_space() invokes
__xdr_commit_encode() to copy enough of the data item back into the
previous page to make that data item contiguous across the page
boundary.
But we need to be careful in the case where buffer space is reserved
early for a data item whose value will be inserted into the buffer
later.
One such caller, nfsd4_encode_operation(), reserves 8 bytes in the
encoding buffer for each COMPOUND operation. However, a READDIR
result can sometimes encode file names so that there are only 4
bytes left at the end of the current XDR buffer page (though plenty
of pages are left to handle the remaining encoding tasks).
If a COMPOUND operation follows the READDIR result (say, a GETATTR),
then nfsd4_encode_operation() will reserve 8 bytes for the op number
(9) and the op status (usually NFS4_OK). In this weird case,
xdr_reserve_space() returns a pointer to byte zero of the next buffer
page, as it assumes the data item will be copied back into place (in
the previous page) on the next call to xdr_reserve_space().
nfsd4_encode_operation() writes the op num into the buffer, then
saves the next 4-byte location for the op's status code. The next
xdr_reserve_space() call is part of GETATTR encoding, so the op num
gets copied back into the previous page, but the saved location for
the op status continues to point to the wrong spot in the current
XDR buffer page because __xdr_commit_encode() moved that data item.
After GETATTR encoding is complete, nfsd4_encode_operation() writes
the op status over the first XDR data item in the GETATTR result.
The NFS4_OK status code (0) makes it look like there are zero items
in the GETATTR's attribute bitmask.
The patch description of commit 2825a7f90753 ("nfsd4: allow encoding
across page boundaries") [2014] remarks that NFSD "can't handle a
new operation starting close to the end of a page." This bug appears
to be one reason for that remark.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pekka Pessi <ppessi@nvidia.com>
commit 0b7f8328f988178b55ee11d772a6e1238c04d29d upstream.
The Tegra RCE (Camera) driver expects the mailbox to be empty before
processing the IVC messages. On RT kernel, the threads processing the
IVC messages (which are invoked after `mbox_chan_received_data()` is
called) may be on a different CPU or running with a higher priority
than the HSP interrupt handler thread. This can cause it to act on the
message before the mailbox gets cleared in the HSP interrupt handler
resulting in a loss of IVC notification.
Fix this by clearing the mailbox data register before calling
`mbox_chan_received_data()`.

commit 110b43ef05342d5a11284cc8b21582b698b4ef1c upstream.
The "pipe" variable is a u8 which comes from the network. If it's more
than 127, then it results in memory corruption in the caller,
nci_hci_connect_gate().

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt <rostedt@goodmis.org>
commit c8c9b1d2d5b4377c72a979f5a26e842a869aefc9 upstream.
The code was restructured where the function graph notrace code, that
would not trace a function and all its children is done by setting a
NOTRACE flag when the function that is not to be traced is hit.
There's a TRACE_GRAPH_NOTRACE_BIT which defines the bit in the flags and a
TRACE_GRAPH_NOTRACE which is the mask with that bit set. But the
restructuring used TRACE_GRAPH_NOTRACE_BIT when it should have used
TRACE_GRAPH_NOTRACE.
For example:
# cd /sys/kernel/tracing
# echo set_track_prepare stack_trace_save > set_graph_notrace
# echo function_graph > current_tracer
# cat trace
[..]
0) | __slab_free() {
0) | free_to_partial_list() {
0) | arch_stack_walk() {
0) | __unwind_start() {
0) 0.501 us | get_stack_info();
Where a non filter trace looks like:
# echo > set_graph_notrace
# cat trace
0) | free_to_partial_list() {
0) | set_track_prepare() {
0) | stack_trace_save() {
0) | arch_stack_walk() {
0) | __unwind_start() {
Where the filter should look like:
# cat trace
0) | free_to_partial_list() {
0) | _raw_spin_lock_irqsave() {
0) 0.350 us | preempt_count_add();

From: Frank Li <Frank.Li@nxp.com>
commit b266e0d4dac00eecdfaf50ec3f708fd0c3b39637 upstream.
Fix a probe failure in the i3c master driver that occurs when no i3c
devices are connected to the bus.
The issue arises in `i3c_master_bus_init()` where the `ret` value is not
updated after calling `master->ops->set_speed()`. If no devices are
present, `ret` remains set to `I3C_ERROR_M2`, causing the code to
incorrectly proceed to `err_bus_cleanup`.

------------------
From: Nick Chan <towinchenmi@gmail.com>
commit 698244bbb3bfd32ddf9a0b70a12b1c7d69056497 upstream.
The CPU PMU in Apple SoCs can be configured to fire its interrupt in one of
several ways, and since Apple A11 one of the methods is FIQ, but the check
of the configuration register fails to test explicitely for FIQ mode. It
tests whether the IMODE bitfield is zero or not and the PMCRO_IACT bit is
set. That results in false positives when the IMODE bitfield is not zero,
but does not have the mode PMCR0_IMODE_FIQ.
Only handle the PMC interrupt as a FIQ when the CPU PMU has been configured
to fire FIQs, i.e. the IMODE bitfield value is PMCR0_IMODE_FIQ and
PMCR0_IACT is set.

From: Ivan Stepchenko <sid@itb.spb.ru>
commit 70a71f8151b9879b0950668ce3ad76263261fee0 upstream.
The function do_otp_read() does not set the output parameter *retlen,
which is expected to contain the number of bytes actually read.
As a result, in onenand_otp_walk(), the tmp_retlen variable remains
uninitialized after calling do_otp_walk() and used to change
the values of the buf, len and retlen variables.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ekansh Gupta <quic_ekangupt@quicinc.com>
commit 6ca4ea1f88a06a04ed7b2c9c6bf9f00833b68214 upstream.
For registered buffers, fastrpc driver sends the buffer information
to remote subsystem. There is a problem with current implementation
where the page address is being sent with an offset leading to
improper buffer address on DSP. This is leads to functional failures
as DSP expects base address in page information and extracts offset
information from remote arguments. Mask the offset and pass the base
page address to DSP.
This issue is observed is a corner case when some buffer which is registered
with fastrpc framework is passed with some offset by user and then the DSP
implementation tried to read the data. As DSP expects base address and takes
care of offsetting with remote arguments, passing an offsetted address will
result in some unexpected data read in DSP.
All generic usecases usually pass the buffer as it is hence is problem is
not usually observed. If someone tries to pass offsetted buffer and then
tries to compare data at HLOS and DSP end, then the ambiguity will be observed.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ekansh Gupta <quic_ekangupt@quicinc.com>
commit e966eae72762ecfdbdb82627e2cda48845b9dd66 upstream.
For non-registered buffer, fastrpc driver copies the buffer and
pass it to the remote subsystem. There is a problem with current
implementation of page size calculation which is not considering
the offset in the calculation. This might lead to passing of
improper and out-of-bounds page size which could result in
memory issue. Calculate page start and page end using the offset
adjusted address instead of absolute address.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Fertser <fercerpav@gmail.com>
commit 6bb194d036c6e1b329dcdff459338cdd9a54802a upstream.
The NCSI state machine as it's currently implemented assumes that
transition to the next logical state is performed either explicitly by
calling `schedule_work(&ndp->work)` to re-queue itself or implicitly
after processing the predefined (ndp->pending_req_num) number of
replies. Thus to avoid the configuration FSM from advancing prematurely
and getting out of sync with the process it's essential to not skip
waiting for a reply.
This patch makes the code wait for reception of the Deselect Package
response for the last package probed before proceeding to channel
configuration.
Thanks go to Potin Lai and Cosmo Chou for the initial investigation and
testing.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Milos Reljin <milos_reljin@outlook.com>
commit bd1bbab717608757cccbbe08b0d46e6c3ed0ced5 upstream.
In application note (AN13663) for TJA1120, on page 30, there's a figure
with average PHY startup timing values following software reset.
The time it takes for SMI to become operational after software reset
ranges roughly from 500 us to 1500 us.
This commit adds 2000 us delay after MDIO write which triggers software
reset. Without this delay, soft_reset function returns an error and
prevents successful PHY init.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Yang <richard.weiyang@gmail.com>
commit 4f6a6bed0bfef4b966f076f33eb4f5547226056a upstream.
Patch series "simplify split calculation", v3.
This patch (of 3):
The current calculation for splitting nodes tries to enforce a minimum
span on the leaf nodes. This code is complex and never worked correctly
to begin with, due to the min value being passed as 0 for all leaves.
The calculation should just split the data as equally as possible
between the new nodes. Note that b_end will be one more than the data,
so the left side is still favoured in the calculation.
The current code may also lead to a deficient node by not leaving enough
data for the right side of the split. This issue is also addressed with
the split calculation change.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt <rostedt@goodmis.org>
commit e3ff4245928f948f3eb2e852aa350b870421c358 upstream.
If a timerlat tracer is started with the osnoise option OSNOISE_WORKLOAD
disabled, but then that option is enabled and timerlat is removed, the
tracepoints that were enabled on timerlat registration do not get
disabled. If the option is disabled again and timelat is started, then it
triggers a warning in the tracepoint code due to registering the
tracepoint again without ever disabling it.
Do not use the same user space defined options to know to disable the
tracepoints when timerlat is removed. Instead, set a global flag when it
is enabled and use that flag to know to disable the events.

commit 80d3ba1cf51bfbbb3b098434f2b2c95cd7c0ae5c upstream.
osnoise_set_workload returns -1 for both missing OSNOISE_WORKLOAD option
and failure in setting the option.
Return -1 for missing and -2 for failure to distinguish them.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomas Glozar <tglozar@redhat.com>
commit d8d866171a414ed88bd0d720864095fd75461134 upstream.
When using rtla timerlat with userspace threads (-u or -U), rtla
disables the OSNOISE_WORKLOAD option in
/sys/kernel/tracing/osnoise/options. This option is not re-enabled in a
subsequent run with kernel-space threads, leading to rtla collecting no
results if the previous run exited abnormally:
$ rtla timerlat hist -u
^\Quit (core dumped)
$ rtla timerlat hist -k -d 1s
Index
over:

The issue persists until OSNOISE_WORKLOAD is set manually by running:
$ echo OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options
Set OSNOISE_WORKLOAD when running rtla with kernel-space threads if
available to fix the issue.

commit e879b5dcf8d044f3865a32d95cc5b213f314c54f upstream.
Support not only turning trace on for the timerlat tracer, but also
turning it off.
This will be used in subsequent patches to stop the timerlat tracer
without also wiping the trace buffer.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomas Glozar <tglozar@redhat.com>
commit c73cab9dbed04d8f65ca69177b4b21ed3e09dfa7 upstream.
Currently, when either SIGINT from the user or SIGALRM from the duration
timer is caught by rtla-timerlat, stop_tracing is set to break out of
the main loop. This is not sufficient for cases where the timerlat
tracer is producing more data than rtla can consume, since in that case,
rtla is looping indefinitely inside tracefs_iterate_raw_events, never
reaches the check of stop_tracing and hangs.
In addition to setting stop_tracing, also stop the timerlat tracer on
received signal (SIGINT or SIGALRM). This will stop new samples so that
the existing samples may be processed and tracefs_iterate_raw_events
eventually exits.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco <javier.carrasco.cruz@gmail.com>
commit 459915f55509f4bfd6076daa1428e28490ddee3b upstream.
Commit 50ebd19e3585 ("pinctrl: samsung: drop pin banks references on
error paths") fixed the pin bank references on the error paths of the
probe function, but there is still an error path where this is not done.
If samsung_pinctrl_get_soc_data() does not fail, the child references
will have acquired, and they will need to be released in the error path
of platform_get_irq_optional(), as it is done in the following error
paths within the probe function.
Replace the direct return in the error path with a goto instruction to
the cleanup function.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
commit accabfaae0940f9427c782bfee7340ce4c15151c upstream.
The PFC_MASK value for the PFC_mx registers is currently hardcoded to
0x07, which is correct for SoCs in the RZ/G2L family, but insufficient
for RZ/V2H and RZ/G3E, where the mask value should be 0x0f. This
discrepancy causes incorrect PFC register configuration on RZ/V2H and
RZ/G3E SoCs.
On RZ/G2L, the PFC_mx bitfields are also 4 bits wide, with bit 4 marked
as reserved. The reserved bits are documented to read as zero and be
ignored when written. Updating the PFC_MASK definition from 0x07 to
0x0f ensures compatibility with both SoC families while maintaining
correct behavior on RZ/G2L.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@weissschuh.net>
commit fd53aa40e65f518453115b6f56183b0c201db26b upstream.
The ioctl and sysfs handlers unconditionally call the ->enable callback.
Not all drivers implement that callback, leading to NULL dereferences.
Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c.
Instead use a dummy callback if no better was specified by the driver.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yishai Hadas <yishaih@nvidia.com>
commit abb604a1a9c87255c7a6f3b784410a9707baf467 upstream.
This patch addresses a race condition for an ODP MR that can result in a
CQE with an error on the UMR QP.
During the __mlx5_ib_dereg_mr() flow, the following sequence of calls
occurs:
mlx5_revoke_mr()
mlx5r_umr_revoke_mr()
mlx5r_umr_post_send_wait()
At this point, the lkey is freed from the hardware's perspective.
However, concurrently, mlx5_ib_invalidate_range() might be triggered by
another task attempting to invalidate a range for the same freed lkey.
This task will:
- Acquire the umem_odp->umem_mutex lock.
- Call mlx5r_umr_update_xlt() on the UMR QP.
- Since the lkey has already been freed, this can lead to a CQE error,
causing the UMR QP to enter an error state [1].
To resolve this race condition, the umem_odp->umem_mutex lock is now also
acquired as part of the mlx5_revoke_mr() scope. Upon successful revoke,
we set umem_odp->private which points to that MR to NULL, preventing any
further invalidation attempts on its lkey.

Clock description in DT binding introduced by commit f69060c14431

clock name but driver is checking "rtc_clk" name instead.
Because clock is optional property likely in was never handled properly by

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miklos Szeredi <mszeredi@redhat.com>
commit e52e97f09fb66fd868260d05bd6b74a9a3db39ee upstream.
Just like it's normal for unset values to be zero, unset strings should be
empty instead of containing random values.
It seems to be a typical mistake that the mask returned by statmount is not
checked, which can result in various bugs.
With this fix, these bugs are prevented, since it is highly likely that
userspace would just want to turn the missing mask case into an empty
string anyway (most of the recently found cases are of this type).

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frederic Weisbecker <frederic@kernel.org>
commit 868c9037df626b3c245ee26a290a03ae1f9f58d3 upstream.
Before attaching a new root to the old root, the children counter of the
new root is checked to verify that only the upcoming CPU's top group have
been connected to it. However since the recently added commit b729cc1ec21a
("timers/migration: Fix another race between hotplug and idle entry/exit")
this check is not valid anymore because the old root is pre-accounted
as a child to the new root. Therefore after connecting the upcoming
CPU's top group to the new root, the children count to be expected must
be 2 and not 1 anymore.
This omission results in the old root to not be connected to the new
root. Then eventually the system may run with more than one top level,
which defeats the purpose of a single idle migrator.
Also the old root is pre-accounted but not connected upon the new root
creation. But it can be connected to the new root later on. Therefore
the old root may be accounted twice to the new root. The propagation of
such overcommit can end up creating a double final top-level root with a
groupmask incorrectly initialized. Although harmless given that the final
top level roots will never have a parent to walk up to, this oddity
opportunistically reported the core issue:
WARNING: CPU: 8 PID: 0 at kernel/time/timer_migration.c:543 tmigr_requires_handle_remote
CPU: 8 UID: 0 PID: 0 Comm: swapper/8

</IRQ>
Fix the problem by taking the old root into account in the children count
of the new root so the connection is not omitted.
Also warn when more than one top level group exists to better detect
similar issues in the future.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <hca@linux.ibm.com>
commit ae02615b7fcea9ce9a4ec40b3c5b5dafd322b179 upstream.
The fixup section was added again by mistake when test_fp_ctl() was
removed. The reason for the removal of the fixup section is described in
commit 484a8ed8b7d1 ("s390/extable: add dedicated uaccess handler").
Remove it again for the same reason.
Add an exception handler which handles exceptions when the floating point
control register is attempted to be set to invalid values. The exception
handler sets the floating point control register to zero and continues
execution at the specified address.
The new sfpc inline assembly is open-coded to make back porting a bit
easier.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bence Csókás <csokas.bence@prolan.hu>
commit be92ab2de0ee1a13291c3b47b2d7eb24d80c0a2c upstream.
The QSPI peripheral control and status registers are
accessible via the SoC's APB bus, whereas MMIO transactions'
data travels on the AHB bus.
Microchip documentation and even sample code from Atmel
emphasises the need for a memory barrier before the first
MMIO transaction to the AHB-connected QSPI, and before the
last write to its registers via APB. This is achieved by
the following lines in `atmel_qspi_transfer()`:
/* Dummy read of QSPI_IFR to synchronize APB and AHB accesses */
(void)atmel_qspi_read(aq, QSPI_IFR);
However, the current documentation makes no mention to
synchronization requirements in the other direction, i.e.
after the last data written via AHB, and before the first
register access on APB.
In our case, we were facing an issue where the QSPI peripheral
would cease to send any new CSR (nCS Rise) interrupts,
leading to a timeout in `atmel_qspi_wait_for_completion()`
and ultimately this panic in higher levels:
ubi0 error: ubi_io_write: error -110 while writing 63108 bytes
to PEB 491:128, written 63104 bytes
After months of extensive research of the codebase, fiddling
around the debugger with kgdb, and back-and-forth with
Microchip, we came to the conclusion that the issue is
probably that the peripheral is still busy receiving on AHB
when the LASTXFER bit is written to its Control Register
on APB, therefore this write gets lost, and the peripheral
still thinks there is more data to come in the MMIO transfer.
This was first formulated when we noticed that doubling the
write() of QSPI_CR_LASTXFER seemed to solve the problem.
Ultimately, the solution is to introduce memory barriers
after the AHB-mapped MMIO transfers, to ensure ordering.

Commit 2190966fbc14 ("x86: Convert unreachable() to BUG()") missed
one.
And after commit 06e24745985c ("objtool: Remove
annotate_{,un}reachable()") the invalid use of unreachable()
(rightfully) triggers warnings:
vmlinux.o: warning: objtool: page_fault_oops() falls through to next function is_prefetch()

From: Dan Carpenter <dan.carpenter@linaro.org>
commit 62c552070a980363d55a6082b432ebd1cade7a6e upstream.
The linear_conf() returns error pointers, it doesn't return NULL. Update
the error checking to match.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bvanassche@acm.org>
commit a572593ac80e51eb69ecede7e614289fcccdbf8d upstream.
queue_limits_cancel_update() must only be called if
queue_limits_start_update() is called first. Remove the
queue_limits_cancel_update() call from linear_set_limits() because
there is no corresponding queue_limits_start_update() call.
This bug was discovered by annotating all mutex operations with clang
thread-safety attributes and by building the kernel with clang and
-Wthread-safety.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com>
commit 04d6273faed083e619fc39a738ab0372b6a4db20 upstream.
This reverts commit 87b7ebc2e16c14d32a912f18206a4d6cc9abc3e8.
A long time ago, we had an issue with the Raven system when it was
connected to two displays: one with DP and another with HDMI. After the
system woke up from suspension, we saw a solid green screen caused by an
underflow generated by bad DCC metadata. To workaround this issue, the
'commit 87b7ebc2e16c ("drm/amd/display: Fix green screen issue after
suspend")' was introduced to disable the DCC for a few frames after in
the resume phase. However, in hindsight, this solution was probably a
workaround at the kernel level for some issues from another part
(probably other driver components or user space). After applying this
patch and trying to reproduce the green issue in a similar hardware
system but using the latest kernel and userspace, we cannot see the
issue, which makes this workaround obsolete and creates extra
unnecessary complexity to the code; for all of this reason, this commit
reverts the original change.

------------------
From: Jeff Layton <jlayton@kernel.org>
commit 056d33137bf9364456ee70aa265ccbb948daee49 upstream.
Currently these mount options aren't accessible via statmount().
The read handler for /proc/#/mountinfo calls security_sb_show_options()
to emit the security options after emitting superblock flag options, but
before calling sb->s_op->show_options.
Have statmount_mnt_opts() call security_sb_show_options() before
calling ->show_options.

6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miklos Szeredi <mszeredi@redhat.com>
commit 5eb987105357cb7cfa7cf3b1e2f66d5c0977e412 upstream.
Prepending security options was made conditional on sb->s_op->show_options,
but security options are independent of sb options.
Fixes: 056d33137bf9 ("fs: prepend statmount.mnt_opts string with security_sb_mnt_opts()")
Fixes: f9af549d1fd3 ("fs: export mount options via statmount()")

CIP testing did not find any problems here:

6.12 passes our testing, too; 6.6 will likely be ok after retries.

Builds & runs fine BUT fails to suspend to RAM 99.99% of the time (basically
one success but never again). Display powers down but fans stay on.
Tested on multiple systems, all x64. I first suspected amdgpu because why not :)
but it also fails on a system without amdgpu, so that's not it.
Reverting to 6.13.2 immediately fixes everything.
Common symptom on all machines seems to be
[ +0.000134] Disabling non-boot CPUs ...
[ +0.000072] Error taking CPU15 down: -16
[ +0.000002] Non-boot CPUs are not disabled
"Error taking down CPUX" is always the highest number of CPU, i.e.
15 on my 16-core Zen2 laptop, 3 on my 4-core Sandybridge etc.
I started to revert suspects but no luck so far:
- acpi parsing order
- amdgpu backlight quirks
- timers/hrtimers
Suggestions for other suspects are welcome.

Can you run 'git bisect' to try to find the offending change?

Can do later today but this is going to take a while - slow HW. :(

Whoop! Whoop! The sound of da police!
2ce2a62881abcd379b714bf41aa671ad7657bdd2 is the first bad commit
commit 2ce2a62881abcd379b714bf41aa671ad7657bdd2 (HEAD)
Author: Juri Lelli <juri.lelli@redhat.com>
Date: Fri Nov 15 11:48:29 2024 +0000
sched/deadline: Check bandwidth overflow earlier for hotplug
[ Upstream commit 53916d5fd3c0b658de3463439dd2b7ce765072cb ]
With this reverted it reliably suspends again.
cheers

Can you check that it works (or - more likely - doesn't work) in upstream?
That commit 53916d5fd3c0 ("sched/deadline: Check bandwidth overflow
earlier for hotplug") got merged during the current merge window, so
it would be lovely if you can check whether current -git (or just the
latest 6.14-rc) works for you, or has the same breakage.
Background for new people on the participants list: original report at
https://lore.kernel.org/all/e7096ec2-68db-fc3e-9c48-f20d3e80df72@applied-asynchrony.com/

and if it breaks in 6.13 -stable, I would expect the same in the
current tree. Unless there's some non-obvious interaction with
something else ?

I just booted into current 6.14-git and could suspend/wakeup multiple times without
any problem - no reverting necessary, so that is good.
As for 6.12/6.13 it might be necessary to revert an accompanying commit
as well since it seems to cause test failures with hotplug, as documented here:
https://lore.kernel.org/stable/bcf76664-e77c-44b3-b78f-bcefc7aa3fc1@nvidia.com/
..but I don't know anything about that; I just wanted to find the patch causing
the suspend problem. Other than that 6.13.3-rc2 works fine.
Not sure if that was useful information. :)
cheers

Commit 53916d5fd3c0 ("sched/deadline: Check bandwidth overflow earlier
for hotplug") is the last patch of the 3 patch series.
1) commit 41d4200b7103 ("sched/deadline: Restore dl_server bandwidth
on non-destructive root domain changes")
2) commit d4742f6ed7ea ("sched/deadline: Correctly account for
allocated bandwidth during hotplug")
3) commit 53916d5fd3c0 ("sched/deadline: Check bandwidth overflow
earlier for hotplug")
It looks like 6.13.3-rc1 has patches 2 and 3, but not patch 1. It is
possible that patch 3 has a dependency on patch 1. My suggestion is to
either take patch 1 as well or none of them.
Cheers,
Longman

Yes, thanks, I'll go drop this other patch from the stable queues as
taking only 1 of a 3 patch series generally isn't good :)

Now that we have 6.13.3-rc3 passing all tests I got curious and applied
the whole series again. And voila: suspend works reliably (3 out of 3).
Mystery solved.
So Greg, feel free to add the whole 3-part series in the next round.

Apologies for looking into this late, but thank you so much, Holger, for

No objection (which is just as well given how late I am in replying)
but I'm just not sure *why*. This doesn't fix a real bug; it's just a
cleanup.
Does this mean I should have written my original commit message better,
to make it clearer that this *isn't* a bugfix?

Yes, that's why it was picked up.

The patch has no fixes: tag and no cc:stable. The burden shouldn't be
on the patch author to sprinkle enough of the right keywords over the
commit log to convince the bot that this is not a suitable stable
candidate, just because it happens to apply without conflicts.

The burden is not there to do that, this came in from the AUTOSEL stuff.
It was sent to everyone on Jan 26:
https://lore.kernel.org/r/20250126150720.961959-3-sashal@kernel.org
so there was 1 1/2 weeks chance to say something before Sasha committed
it to the stable queue. Then it was sent out again here in the -rc
releases for review, for anyone to object to.
So there was 3 different times someone could have said "no, this isn't
ok for stable inclusion" before it was merged. And even if that's not
enough, I'll be glad to revert it if it wasn't ok to be merged at any
time afterward.

Yeah, that is what I figured. Can we *please* stop doing stupid stuff
like that for arch code, especially arch/x86, which is well looked
after? (In my personal opinion, we should not be using AUTOSEL at all,
but that seems to be a lost battle)
Especially for this patch in particular, which touches the kexec code,
which is easy to break and difficult to fix. Whether the patch applies
without breaking the build is entirely irrelevant (and even that seems
a high bar for stable trees these days). Nobody should be touching any
of that code without actually testing whether or not kexec still
works.

There should not be a need for people to object to something that no
actual person ever suggested in the first place.
The only responsible way to use AUTOSEL is to make it opt-in rather
than opt-out. And I object to the idea that it is ok for someone like
Sasha to run a bot that generates lots of emails to lots of people,
and put the burden on everyone else to spend actual time and mental
effort to go over all those patches and decide whether or not they
might the stable candidates, especially without any due diligence
whatsoever regarding whether the resulting kernel still boots and runs
correctly on a system that actually exercises the updated code.

FWIW I don't think there's any need to revert it; it's fine. Just not
entirely necessary. I did see it in January but I was travelling so I
didn't get past briefly wondering *why* it was being picked up; I
thought perhaps one of the x86 maintainers had actually chosen to do
so.
If I'd *objected*, I'd have found the time to do so then.

Maintainers can ask for their portions of the kernel to be not included
in the AUTOSEL work, and many have, please see:
https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/ignore_list
for the current list of things that are excluded.

That does not work at all. The whole reason AUTOSEL is used is because
maintainers and developers are NOT tagging things that are bugfixes. We
have whole subsystems that just don't do anything, and this is the only
way we can get fixes for that area included in stable kernels.
Again, we allow any subsystem to opt-out entirely from this if they so
desire, AND we allow many chances for a patch to be dropped, AND we
later allow anything to be reverted. Heck, we have maintainers who just
don't want to deal with stable kernels at all, and that's fine, I'm not
going to impose that burden on them if they do not want to. But in that
case, we will do spelunking through the tree to find stuff that affects
users.
If you look at the history of AUTOSEL, I think the number of real bugs
has shown that overall, it works really well. Sure it will mess up at
times, we're all human, and all we can do then is to be sure to react
and fix the issue.
