6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
[ Upstream commit 1ab33c03145d0f6c345823fc2da935d9a1a9e9fc ]
__put_unaligned_be24() and friends use implicit casts to convert
larger-sized data to bytes, which trips sparse truncation warnings when
the argument is a constant:
CC [M] drivers/input/touchscreen/hynitron_cstxxx.o
CHECK drivers/input/touchscreen/hynitron_cstxxx.c
drivers/input/touchscreen/hynitron_cstxxx.c: note: in included file (through arch/x86/include/generated/asm/unaligned.h):
include/asm-generic/unaligned.h:119:16: warning: cast truncates bits from constant value (aa01a0 becomes a0)
include/asm-generic/unaligned.h:120:20: warning: cast truncates bits from constant value (aa01 becomes 1)
include/asm-generic/unaligned.h:119:16: warning: cast truncates bits from constant value (ab00d0 becomes d0)
include/asm-generic/unaligned.h:120:20: warning: cast truncates bits from constant value (ab00 becomes 0)
To avoid this let's mask off upper bits explicitly, the resulting code
should be exactly the same, but it will keep sparse happy.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Huang Shijie <shijie@os.amperecomputing.com>
[ Upstream commit 75b5e0bf90bffaca4b1f19114065dc59f5cc161f ]
In current code, init_irq_stacks() will call cpu_to_node().
The cpu_to_node() depends on percpu "numa_node" which is initialized in:
arch_call_rest_init() --> rest_init() -- kernel_init()
--> kernel_init_freeable() --> smp_prepare_cpus()
But init_irq_stacks() is called in init_IRQ() which is before
arch_call_rest_init().
So in init_irq_stacks(), the cpu_to_node() does not work, it
always return 0. In NUMA, it makes the node 1 cpu accesses the IRQ stack which
is in the node 0.
This patch fixes it by:
1.) export the early_cpu_to_node(), and use it in the init_irq_stacks().
2.) change init_irq_stacks() to __init function.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Rutland <mark.rutland@arm.com>
[ Upstream commit ca6f537e459e2da4b331fe8928d1a0b0f9301f42 ]
The SW_INCR event is somewhat unusual, and depends on the specific HW
counter that it is programmed into. When programmed into PMEVCNTR<n>,
SW_INCR will count any writes to PMSWINC_EL0 with bit n set, ignoring
writes to SW_INCR with bit n clear.
Event rotation means that there's no fixed relationship between
perf_events and HW counters, so this isn't all that useful.
Further, we program PMUSERENR.{SW,EN}=={0,0}, which causes EL0 writes to
PMSWINC_EL0 to be trapped and handled as UNDEFINED, resulting in a
SIGILL to userspace.
Given that, it's not a good idea to expose SW_INCR in sysfs. Hide it as
we did for CHAIN back in commit:

------------------
From: Michael Ellerman <mpe@ellerman.id.au>
[ Upstream commit d8c3f243d4db24675b653f0568bb65dae34e6455 ]
With NUMA=n and FA_DUMP=y or PRESERVE_FA_DUMP=y the build fails with:
arch/powerpc/kernel/fadump.c:1739:22: error: no previous prototype for ‘arch_reserved_kernel_pages’ [-Werror=missing-prototypes]
1739 | unsigned long __init arch_reserved_kernel_pages(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
The prototype for arch_reserved_kernel_pages() is in include/linux/mm.h,
but it's guarded by __HAVE_ARCH_RESERVED_KERNEL_PAGES. The powerpc
headers define __HAVE_ARCH_RESERVED_KERNEL_PAGES in asm/mmzone.h, which
is not included into the generic headers when NUMA=n.
Move the definition of __HAVE_ARCH_RESERVED_KERNEL_PAGES into asm/mmu.h
which is included regardless of NUMA=n.
Additionally the ifdef around __HAVE_ARCH_RESERVED_KERNEL_PAGES needs to
also check for CONFIG_PRESERVE_FA_DUMP.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Ellerman <mpe@ellerman.id.au>
[ Upstream commit ede66cd22441820cbd399936bf84fdc4294bc7fa ]
With CONFIG_NUMA=n the build fails with:
arch/powerpc/mm/book3s64/pgtable.c:275:15: error: no previous prototype for ‘create_section_mapping’ [-Werror=missing-prototypes]
275 | int __meminit create_section_mapping(unsigned long start, unsigned long end,
| ^~~~~~~~~~~~~~~~~~~~~~
That happens because the prototype for create_section_mapping() is in
asm/mmzone.h, but asm/mmzone.h is only included by linux/mmzone.h
when CONFIG_NUMA=y.
In fact the prototype is only needed by arch/powerpc/mm code, so move
the prototype into arch/powerpc/mm/mmu_decl.h, which also fixes the
build error.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jun'ichi Nomura <junichi.nomura@nec.com>
[ Upstream commit 78a509fba9c9b1fcb77f95b7c6be30da3d24823a ]
When there are two racing NMIs on x86, the first NMI invokes NMI handler and
the 2nd NMI is latched until IRET is executed.
If panic on NMI and panic kexec are enabled, the first NMI triggers
panic and starts booting the next kernel via kexec. Note that the 2nd
NMI is still latched. During the early boot of the next kernel, once
an IRET is executed as a result of a page fault, then the 2nd NMI is
unlatched and invokes the NMI handler.
However, NMI handler is not set up at the early stage of boot, which
results in a boot failure.
Avoid such problems by setting up a NOP handler for early NMIs.

From: Naveen N Rao <naveen@kernel.org>
[ Upstream commit 8f9abaa6d7de0a70fc68acaedce290c1f96e2e59 ]
Some of the fp/vmx code in sstep.c assume a certain maximum size for the
instructions being emulated. The size of those operations however is
determined separately in analyse_instr().
Add a check to validate the assumption on the maximum size of the
operations, so as to prevent any unintended kernel stack corruption.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhiquan Li <zhiquan1.li@intel.com>
[ Upstream commit 9f3b130048bfa2e44a8cfb1b616f826d9d5d8188 ]
Memory errors don't happen very often, especially fatal ones. However,
in large-scale scenarios such as data centers, that probability
increases with the amount of machines present.
When a fatal machine check happens, mce_panic() is called based on the
severity grading of that error. The page containing the error is not
marked as poison.
However, when kexec is enabled, tools like makedumpfile understand when
pages are marked as poison and do not touch them so as not to cause
a fatal machine check exception again while dumping the previous
kernel's memory.
Therefore, mark the page containing the error as poisoned so that the
kexec'ed kernel can avoid accessing the page.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Raghavendra K T <raghavendra.kt@amd.com>
[ Upstream commit 84db47ca7146d7bd00eb5cf2b93989a971c84650 ]
Since commit fc137c0ddab2 ("sched/numa: enhance vma scanning logic")
NUMA Balancing allows updating PTEs to trap NUMA hinting faults if the
task had previously accessed VMA. However unconditional scan of VMAs are
allowed during initial phase of VMA creation until process's
mm numa_scan_seq reaches 2 even though current task had not accessed VMA.
Rationale:
- Without initial scan subsequent PTE update may never happen.
- Give fair opportunity to all the VMAs to be scanned and subsequently
understand the access pattern of all the VMAs.
But it has a corner case where, if a VMA is created after some time,
process's mm numa_scan_seq could be already greater than 2.
For e.g., values of mm numa_scan_seq when VMAs are created by running
mmtest autonuma benchmark briefly looks like:
start_seq=0 : 459
start_seq=2 : 138
start_seq=3 : 144
start_seq=4 : 8
start_seq=8 : 1
start_seq=9 : 1
This results in no unconditional PTE updates for those VMAs created after
some time.
Fix:
- Note down the initial value of mm numa_scan_seq in per VMA start_seq.
- Allow unconditional scan till start_seq + 2.
Result:
SUT: AMD EPYC Milan with 2 NUMA nodes 256 cpus.
base kernel: upstream 6.6-rc6 with Mels patches [1] applied.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrzej Hajda <andrzej.hajda@intel.com>
[ Upstream commit 9bb6362652f3f4d74a87d572a91ee1b38e673ef6 ]
After release of the hashbucket lock the tracking object can be modified or
freed by a concurrent thread. Using it in such a case is error prone, even
for printing the object state:
1. T1 tries to deactivate destroyed object, debugobjects detects it,
hash bucket lock is released.
2. T2 preempts T1 and frees the tracking object.
3. The freed tracking object is allocated and initialized for a
different to be tracked kernel object.
4. T1 resumes and reports error for wrong kernel object.
Create a local copy of the tracking object before releasing the hash bucket
lock and use the local copy for reporting and fixups to prevent this.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vincent Guittot <vincent.guittot@linaro.org>
[ Upstream commit f60a631ab9ed5df15e446269ea515f2b8948ba0c ]
When a CPU is taken offline, the contribution of its cfs_rqs to task_groups'
load may remain and will negatively impact the calculation of the share of
the online CPUs.
To fix this bug, clear the contribution of an offlining CPU to task groups'
load and skip its contribution while it is inactive.
Here's the reproducer of the anomaly, by Imran Khan:
"So far I have encountered only one rather lengthy way of reproducing this issue,
which is as follows:
1. Take a KVM guest (booted with 4 CPUs and can be scaled up to 124 CPUs) and
create 2 custom cgroups: /sys/fs/cgroup/cpu/test_group_1 and /sys/fs/cgroup/
cpu/test_group_2
2. Assign a CPU intensive workload to each of these cgroups and start the
workload.
For my tests I am using following app:
int main(int argc, char *argv[])
{
unsigned long count, i, val;
if (argc != 2) {
printf("usage: ./a.out <number of random nums to generate> \n");
return 0;
}
count = strtoul(argv[1], NULL, 10);
printf("Generating %lu random numbers \n", count);
for (i = 0; i < count; i++) {
val = rand();
val = val % 2;
//usleep(1);
}
printf("Generated %lu random numbers \n", count);
return 0;
}
Also since the system is booted with 4 CPUs, in order to completely load the
system I am also launching 4 instances of same test app under:
/sys/fs/cgroup/cpu/
3. We can see that both of the cgroups get similar CPU time:
# systemd-cgtop --depth 1

4. Now move systemd-udevd to one of these test groups, say test_group_1, and
perform scale up to 124 CPUs followed by scale down back to 4 CPUs from the
host side.
5. Run the same workload i.e 4 instances of CPU hogger under /sys/fs/cgroup/cpu
and one instance of CPU hogger each in /sys/fs/cgroup/cpu/test_group_1 and
/sys/fs/cgroup/test_group_2.
It can be seen that test_group_1 (the one where systemd-udevd was moved) is getting
much less CPU time than the test_group_2, even though at this point of time both of
these groups have only CPU hogger running:

From sched_debug data it can be seen that in bad case the load.weight of per-CPU
sched entities corresponding to test_group_1 has reduced significantly and
also load_avg of test_group_1 remains much higher than that of test_group_2,
even though systemd-udevd stopped running long time back and at this point of
time both cgroups just have the CPU hogger app as running entity."

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rui Zhang <zr.zhang@vivo.com>
[ Upstream commit 7993d3a9c34f609c02171e115fd12c10e2105ff4 ]
The use_count of a regulator should only be incremented when the
enable_count changes from 0 to 1. Similarly, the use_count should
only be decremented when the enable_count changes from 1 to 0.
In the previous implementation, use_count was sometimes decremented
to 0 when some consumer called unbalanced disable,
leading to unexpected disable even the regulator is enabled by
other consumers. With this change, the use_count accurately reflects
the number of users which the regulator is enabled.
This should make things more robust in the case where a consumer does
leak references.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Riches <chris.riches@nutanix.com>
[ Upstream commit 022732e3d846e197539712e51ecada90ded0572a ]
When auditd_set sets the auditd_conn pointer, audit messages can
immediately be put on the socket by other kernel threads. If the backlog
is large or the rate is high, this can immediately fill the socket
buffer. If the audit daemon requested an ACK for this operation, a full
socket buffer causes the ACK to get dropped, also setting ENOBUFS on the
socket.
To avoid this race and ensure ACKs get through, fast-track the ACK in
this specific case to ensure it is sent before auditd_conn is set.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuntao Wang <ytcoode@gmail.com>
[ Upstream commit 4b3805daaacb2168665c6222f261e68accb120dc ]
The original intention of acpi_parse_entries_array() is to return the
number of all matching entries on success. This number may be greater than
the value of the max_entries parameter. When this happens, the function
will output a warning message, indicating that `count - max_entries`
matching entries remain unprocessed and have been ignored.
However, commit 4ceacd02f5a1 ("ACPI / table: Always count matched and
successfully parsed entries") changed this logic to return the number of
entries successfully processed by the handler. In this case, when the
max_entries parameter is not zero, the number of entries successfully
processed can never be greater than the value of max_entries. In other
words, the expression `count > max_entries` will always evaluate to false.
This means that the logic in the final if statement will never be executed.
Commit 99b0efd7c886 ("ACPI / tables: do not report the number of entries
ignored by acpi_parse_entries()") mentioned this issue, but it tried to fix
it by removing part of the warning message. This is meaningless because the
pr_warn statement will never be executed in the first place.
Commit 8726d4f44150 ("ACPI / tables: fix acpi_parse_entries_array() so it
traverses all subtables") introduced an errs variable, which is intended to
make acpi_parse_entries_array() always traverse all of the subtables,
calling as many of the callbacks as possible. However, it seems that the
commit does not achieve this goal. For example, when a handler returns an
error, none of the handlers will be called again in the subsequent
iterations. This result appears to be no different from before the change.
This patch corrects and cleans up the logic of acpi_parse_entries_array(),
making it return the number of all matching entries, rather than the number
of entries successfully processed by handlers. Additionally, if an error
occurs when executing a handler, the function will return -EINVAL immediately.
This patch should not affect existing users of acpi_parse_entries_array().

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuluo Qiu <qyl27@outlook.com>
[ Upstream commit 143176a46bdd3bfbe9ba2462bf94458e80d65ebf ]
The Colorful X15 AT 23 ACPI video-bus device report spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there) when
an external screen plugged in.
Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.

From: Dmitry Antipov <dmantipov@yandex.ru>
[ Upstream commit ba3f5058db437d919f8468db50483dd9028ff688 ]
When compiling with gcc version 14.0.0 20231126 (experimental)
and CONFIG_FORTIFY_SOURCE=y, I've noticed the following:

588 | __read_overflow2_field(q_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
According to the comments in include/linux/fortify-string.h, 'memcpy()',
'memmove()' and 'memset()' must not be used beyond individual struct
members to ensure that the compiler can enforce protection against
buffer overflows, and, IIUC, this also applies to partial copies from
the particular member ('vendor->byte_data' in this case). So it should
be better (and safer) to do both copies at once (and 'byte_data' of
'struct acpi_resource_vendor_typed' seems to be a good candidate for
'__counted_by(byte_length)' as well).

[ Upstream commit 72d9b9747e78979510e9aafdd32eb99c7aa30dd1 ]
The gcc plugin -fanalyzer [1] tries to detect various
patterns of incorrect behaviour. The tool reports:

From: Yuntao Wang <ytcoode@gmail.com>
[ Upstream commit e3f577830ce216b0ca21d4750cbbd64cfc21efff ]
The for loop does not iterate over the last element of the node_to_pxm_map
array. This could lead to a conflict between the final fake_pxm value and
the existing pxm values. That is, the final fake_pxm value can not be
guaranteed to be an unused pxm value.
While at it, fix up white space in slit_valid().

[ Upstream commit 8ae27bc7fff4ef467a7964821a6cedb34a05d3b2 ]
Add parsing of attributes as diagnostic data. Fixes issue with test plan
being parsed incorrectly as diagnostic data when located after
suite-level attributes.
Note that if there does not exist a test plan line, the diagnostic lines
between the suite header and the first result will be saved in the suite
log rather than the first test case log.

[ Upstream commit 342fb9789267ee3908959bfa136b82e88e2ce918 ]
If we run parameterized test that uses test->priv to prepare some
custom data, then value of test->priv will leak to the next param
iteration and may be unexpected. This could be easily seen if
we promote example_priv_test to parameterized test as then only
first test iteration will be successful:

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mukesh Ojha <quic_mojha@quicinc.com>
[ Upstream commit aed5ed595960c6d301dcd4ed31aeaa7a8054c0c6 ]
There is a chance if a frequent switch of the governor
done in a loop result in timer list corruption where
timer cancel being done from two place one from
cancel_delayed_work_sync() and followed by expire_timers()
can be seen from the traces[1].
while true
do
echo "simple_ondemand" > /sys/class/devfreq/1d84000.ufshc/governor
echo "performance" > /sys/class/devfreq/1d84000.ufshc/governor
done
It looks to be issue with devfreq driver where
device_monitor_[start/stop] need to synchronized so that
delayed work should get corrupted while it is either
being queued or running or being cancelled.
Let's use polling flag and devfreq lock to synchronize the
queueing the timer instance twice and work data being
corrupted.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shuai Xue <xueshuai@linux.alibaba.com>
[ Upstream commit a70297d2213253853e95f5b49651f924990c6d3b ]
There are two major types of uncorrected recoverable (UCR) errors :
- Synchronous error: The error is detected and raised at the point of
the consumption in the execution flow, e.g. when a CPU tries to
access a poisoned cache line. The CPU will take a synchronous error
exception such as Synchronous External Abort (SEA) on Arm64 and
Machine Check Exception (MCE) on X86. OS requires to take action (for
example, offline failure page/kill failure thread) to recover this
uncorrectable error.
- Asynchronous error: The error is detected out of processor execution
context, e.g. when an error is detected by a background scrubber.
Some data in the memory are corrupted. But the data have not been
consumed. OS is optional to take action to recover this uncorrectable
error.
When APEI firmware first is enabled, a platform may describe one error
source for the handling of synchronous errors (e.g. MCE or SEA notification
), or for handling asynchronous errors (e.g. SCI or External Interrupt
notification). In other words, we can distinguish synchronous errors by
APEI notification. For synchronous errors, kernel will kill the current
process which accessing the poisoned page by sending SIGBUS with
BUS_MCEERR_AR. In addition, for asynchronous errors, kernel will notify the
process who owns the poisoned page by sending SIGBUS with BUS_MCEERR_AO in
early kill mode. However, the GHES driver always sets mf_flags to 0 so that
all synchronous errors are handled as asynchronous errors in memory failure.
To this end, set memory failure flags as MF_ACTION_REQUIRED on synchronous
events.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
[ Upstream commit 4e814173a8c4f432fd068b1c796f0416328c9d99 ]
There are 3 synchronization issues with thermal zone suspend-resume
during system-wide transitions:
1. The resume code runs in a PM notifier which is invoked after user
space has been thawed, so it can run concurrently with user space
which can trigger a thermal zone device removal. If that happens,
the thermal zone resume code may use a stale pointer to the next
list element and crash, because it does not hold thermal_list_lock
while walking thermal_tz_list.
2. The thermal zone resume code calls thermal_zone_device_init()
outside the zone lock, so user space or an update triggered by
the platform firmware may see an inconsistent state of a
thermal zone leading to unexpected behavior.
3. Clearing the in_suspend global variable in thermal_pm_notify()
allows __thermal_zone_device_update() to continue for all thermal
zones and it may as well run before the thermal_tz_list walk (or
at any point during the list walk for that matter) and attempt to
operate on a thermal zone that has not been resumed yet. It may
also race destructively with thermal_zone_device_init().
To address these issues, add thermal_list_lock locking to
thermal_pm_notify(), especially arount the thermal_tz_list,
make it call thermal_zone_device_init() back-to-back with
__thermal_zone_device_update() under the zone lock and replace
in_suspend with per-zone bool "suspend" indicators set and unset
under the given zone's lock.

Rebooting in 86400 seconds..
The issue is caused when the value of lp becomes greater than
CTLTREESIZE which is the max size of stree. Adding a simple check
solves this issue.
Dave:
As the function returns a void, good error handling
would require a more intrusive code reorganization, so I modified
Osama's patch at use WARN_ON_ONCE for lack of a cleaner option.
The patch is tested via syzbot.

The issue is caused when the value of fsi becomes less than -1.
The check to break the loop when fsi value becomes -1 is present
but syzbot was able to produce value less than -1 which cause the error.
This patch simply add the change for the values less than 0.
The patch is tested via syzbot.

which is required to determine the size as suggest in the following
commit.

[ Upstream commit e0e1958f4c365e380b17ccb35617345b31ef7bf3 ]
When the execution of diMount(ipimap) fails, the object ipimap that has been
released may be accessed in diFreeSpecial(). Asynchronous ipimap release occurs
when rcu_core() calls jfs_free_node().
Therefore, when diMount(ipimap) fails, sbi->ipimap should not be initialized as
ipimap.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gustavo A. R. Silva <gustavoars@kernel.org>
[ Upstream commit aaa03fdb56c781db4a4831dd5d6ec8817918c726 ]
The compiler doesn't know that `32` is an offset into the Hash table:
56 struct Hash_ctx {
57 u8 H[16]; /* subkey */
58 u8 Htable[256]; /* Xi, Hash table(offset 32) */
59 };
So, it legitimately complains about a potential out-of-bounds issue
if `256 bytes` are accessed in `htable` (this implies going
`32 bytes` beyond the boundaries of `Htable`):
arch/powerpc/crypto/aes-gcm-p10-glue.c: In function 'gcmp10_init':
arch/powerpc/crypto/aes-gcm-p10-glue.c:120:9: error: 'gcm_init_htable' accessing 256 bytes in a region of size 224 [-Werror=stringop-overflow=]
120 | gcm_init_htable(hash->Htable+32, hash->H);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Address this by avoiding specifying the size of `htable` in the function
prototype; and just for consistency, do the same for parameter `Xi`.

From: Weichen Chen <weichen.chen@mediatek.com>
[ Upstream commit d49270a04623ce3c0afddbf3e984cb245aa48e9c ]
When the number of cpu cores is adjusted to 7 or other odd numbers,
the zone size will become an odd number.
The address of the zone will become:
addr of zone0 = BASE
addr of zone1 = BASE + zone_size
addr of zone2 = BASE + zone_size*2
...
The address of zone1/3/5/7 will be mapped to non-alignment va.
Eventually crashes will occur when accessing these va.
So, use ALIGN_DOWN() to make sure the zone size is even
to avoid this bug.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gao Xiang <hsiangkao@linux.alibaba.com>
[ Upstream commit 8d2517aaeea3ab8651bb517bca8f3c8664d318ea ]
Previously, the block size always equaled to PAGE_SIZE, therefore
`lclusterbits` couldn't be less than 12.
Since sub-page compressed blocks are now considered, `lobits` for
a lcluster in each pack cannot always be `lclusterbits` as before.
Otherwise, there is no enough room for the special value
`Z_EROFS_LI_D0_CBLKCNT`.
To support smaller block sizes, `lobits` for each compacted lcluster is
now calculated as:
lobits = max(lclusterbits, ilog2(Z_EROFS_LI_D0_CBLKCNT) + 1)

From: Bharat Bhushan <bbhushan2@marvell.com>
[ Upstream commit c480a421a4faf693c38e60b0fe6e554c9a3fee02 ]
This patch fixes following cleanup issues:
- Missing instruction queue free on cleanup. This
will lead to memory leak.
- lfs->lfs_num is set to zero before cleanup, which
will lead to improper cleanup.

From: Thomas Bourgoin <thomas.bourgoin@foss.st.com>
[ Upstream commit 0eaef675b94c746900dcea7f6c41b9a103ed5d53 ]
smatch warnings:
drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn:
can 'crc' even be NULL?
Use list_first_entry_or_null instead of list_first_entry to retrieve
the first device registered.
The function list_first_entry always return a non NULL pointer even if
the list is empty. Hence checking if the pointer returned is NULL does
not tell if the list is empty or not.

From: Oleg Nesterov <oleg@redhat.com>
[ Upstream commit 4121b4337146b64560d1e46ebec77196d9287802 ]
David Howells says:
(2) afs_lookup_volume_rcu().
There can be a lot of volumes known by a system. A thousand would
require a 10-step walk and this is drivable by remote operation, so I
think this should probably take a lock on the second pass too.
Make the "seq" counter odd on the 2nd pass, otherwise read_seqbegin_or_lock()
never takes the lock.

[Analysis]
When the agstart is too large, it can cause agno overflow.
[Fix]
After obtaining agno, if the value is invalid, exit the subsequent process.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Gordeev <agordeev@linux.ibm.com>
[ Upstream commit 65f8780e2d70257200547b5a7654974aa7c37ce1 ]
The size of vmalloc area depends from various factors
on boot and could be set to:
1. Default size as determined by VMALLOC_DEFAULT_SIZE macro;
2. One half of the virtual address space not occupied by
modules and fixed mappings;
3. The size provided by user with vmalloc= kernel command
line parameter;
In cases [1] and [2] the vmalloc area base address is aligned
on Region3 table type boundary, while in case [3] in might get
aligned on page boundary.
Limit the waste of page tables and always align vmalloc area
size and base address on segment boundary.

------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 64bac5ea17d527872121adddfee869c7a0618f8f ]
The prototype was hidden in an #ifdef on x86, which causes a warning:
kernel/irq_work.c:72:13: error: no previous prototype for 'arch_irq_work_raise' [-Werror=missing-prototypes]
Some architectures have a working prototype, while others don't.
Fix this by providing it in only one place that is always visible.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 4d86896793dd6eeacdf32b85af1ef130349db4be ]
When -Wmissing-prototypes is enabled, the some asm-offsets.c files fail
to build, even when this warning is disabled in the Makefile for normal
files:
arch/sparc/kernel/asm-offsets.c:22:5: error: no previous prototype for 'sparc32_foo' [-Werror=missing-prototypes]
arch/sparc/kernel/asm-offsets.c:48:5: error: no previous prototype for 'foo' [-Werror=missing-prototypes]
Address this by making use of the same trick as x86, marking these
functions as 'static __used' to avoid the need for a prototype
by not drop them in dead-code elimination.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tony Krowiak <akrowiak@linux.ibm.com>
[ Upstream commit a0d8f4eeb7c4ffaee21702bcc91a09b3988c5b7a ]
The 'status' attribute for AP queue devices bound to the vfio_ap device
driver displays incorrect status when the mediated device is attached to a
guest, but the queue device is not passed through. In the current
implementation, the status displayed is 'in_use' which is not correct; it
should be 'assigned'. This can happen if one of the queue devices
associated with a given adapter is not bound to the vfio_ap device driver.
For example:
Queues listed in /sys/bus/ap/drivers/vfio_ap:
14.0005
14.0006
14.000d
16.0006
16.000d
Queues listed in /sys/devices/vfio_ap/matrix/$UUID/matrix
14.0005
14.0006
14.000d
16.0005
16.0006
16.000d
Queues listed in /sys/devices/vfio_ap/matrix/$UUID/guest_matrix
14.0005
14.0006
14.000d
The reason no queues for adapter 0x16 are listed in the guest_matrix is
because queue 16.0005 is not bound to the vfio_ap device driver, so no
queue associated with the adapter is passed through to the guest;
therefore, each queue device for adapter 0x16 should display 'assigned'
instead of 'in_use', because those queues are not in use by a guest, but

Let's check the AP configuration for the guest to determine whether a
queue device is passed through before displaying a status of 'in_use'.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <hca@linux.ibm.com>
[ Upstream commit 8b13601d19c541158a6e18b278c00ba69ae37829 ]
If the content of the floating point control (fpc) register of a traced
process is modified with the ptrace interface the new value is tested for
validity by temporarily loading it into the fpc register.
This may lead to corruption of the fpc register of the tracing process:
if an interrupt happens while the value is temporarily loaded into the
fpc register, and within interrupt context floating point or vector
registers are used, the current fp/vx registers are saved with
save_fpu_regs() assuming they belong to user space and will be loaded into
fp/vx registers when returning to user space.
test_fp_ctl() restores the original user space fpc register value, however
it will be discarded, when returning to user space.
In result the tracer will incorrectly continue to run with the value that
was supposed to be used for the traced process.
Fix this by saving fpu register contents with save_fpu_regs() before using
test_fp_ctl().

------------------
From: Heiko Carstens <hca@linux.ibm.com>
[ Upstream commit b988b1bb0053c0dcd26187d29ef07566a565cf55 ]
kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control
(fpc) register of a guest cpu. The new value is tested for validity by
temporarily loading it into the fpc register.
This may lead to corruption of the fpc register of the host process:
if an interrupt happens while the value is temporarily loaded into the fpc
register, and within interrupt context floating point or vector registers
are used, the current fp/vx registers are saved with save_fpu_regs()
assuming they belong to user space and will be loaded into fp/vx registers
when returning to user space.
test_fp_ctl() restores the original user space / host process fpc register
value, however it will be discarded, when returning to user space.
In result the host process will incorrectly continue to run with the value
that was supposed to be used for a guest cpu.
Fix this by simply removing the test. There is another test right before
the SIE context is entered which will handles invalid values.
This results in a change of behaviour: invalid values will now be accepted
instead of that the ioctl fails with -EINVAL. This seems to be acceptable,
given that this interface is most likely not used anymore, and this is in
addition the same behaviour implemented with the memory mapped interface
(replace invalid values with zero) - see sync_regs() in kvm-s390.c.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joel Granados <j.granados@samsung.com>
[ Upstream commit 315552310c7de92baea4e570967066569937a843 ]
When registering tables to the sysctl subsystem there is a check to see
if header is a permanently empty directory (used for mounts). This check
evaluates the first element of the ctl_table. This results in an out of
bounds evaluation when registering empty directories.
The function register_sysctl_mount_point now passes a ctl_table of size
1 instead of size 0. It now relies solely on the type to identify
a permanently empty register.
Make sure that the ctl_table has at least one element before testing for
permanent emptiness.

The problem seems to be that two out of three callers aren't taking the
rcu_read_lock() before calling the list_for_each_entry_rcu() function in
rpc_xprt_switch_has_addr(). I fix this by having
rpc_xprt_switch_has_addr() unconditionaly take the rcu_read_lock(),
which is okay to do recursively in the case that the lock has already
been taken by a caller.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ojaswin Mujoo <ojaswin@linux.ibm.com>
[ Upstream commit 92573369144f40397e8514440afdf59f24905b40 ]
The call to filemap_write_and_wait_range() assumes the range passed to be
inclusive, so fix the call to make sure we follow that.

------------------
From: Paulo Alcantara <pc@manguebit.com>
[ Upstream commit 7435d51b7ea2ab7801279c43ecd72063e9d5c92f ]
The client was sending an SMB2_CREATE request without setting
OPEN_REPARSE_POINT flag thus failing the entire rename operation.
Fix this by setting OPEN_REPARSE_POINT in create options for
SMB2_CREATE request when the source inode is a repase point.

From: Shyam Prasad N <sprasad@microsoft.com>
[ Upstream commit 516eea97f92f1e7271f20835cfe9e73774b0f8cc ]
Recently, cifs_chan_update_iface was modified to not
remove an iface if a suitable replacement was not found.
With that, there were two conditionals that were exactly
the same. This change removes that extra condition check.
Also, fixed a logging in the same function to indicate
the correct message.

[ Upstream commit cd72c7ef5fed44272272a105b1da22810c91be69 ]
Even though it seems to be able to resolve some names of
case-insensitive directories, the lack of d_hash and d_compare means we
end up with a broken state in the d_cache. Considering it was never a
goal to support these two together, and we are preparing to use
d_revalidate in case-insensitive filesystems, which would make the
combination even more broken, reject any attempt to get a casefolded
inode from ecryptfs.

From: Ye Bin <yebin10@huawei.com>
[ Upstream commit 68da4c44b994aea797eb9821acb3a4a36015293e ]
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

------------------
From: Baokun Li <libaokun1@huawei.com>
[ Upstream commit 658a52344fb139f9531e7543a6e0015b630feb38 ]
The maximum value of flexbg_size is 2^31, but the maximum value of int
is (2^31 - 1), so overflow may occur when the type of flexbg_size is
declared as int.
For example, when uninit_mask is initialized in ext4_alloc_group_tables(),
if flexbg_size == 2^31, the initialized uninit_mask is incorrect, and this
may causes set_flexbg_block_bitmap() to trigger a BUG_ON().
Therefore, the flexbg_size type is declared as unsigned int to avoid
overflow and memory waste.

[ Upstream commit b099eb87de105cf07cad731ded6fb40b2675108b ]
In commit 967ac8af4475 ("ext4: fix potential integer overflow in
alloc_flex_gd()"), an overflow check is added to alloc_flex_gd() to
prevent the allocated memory from being smaller than expected due to
the overflow. However, after kmalloc() is replaced with kmalloc_array()
in commit 6da2ec56059c ("treewide: kmalloc() -> kmalloc_array()"), the
kmalloc_array() function has an overflow check, so the above problem
will not occur. Therefore, the extra check is removed.

This is because flexbg_size is too large and the size of the new_group_data
array to be allocated exceeds MAX_ORDER. Currently, the minimum value of
MAX_ORDER is 8, the minimum value of PAGE_SIZE is 4096, the corresponding
maximum number of groups that can be allocated is:
(PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845
And the value that is down-aligned to the power of 2 is 16384. Therefore,
this value is defined as MAX_RESIZE_BG, and the number of groups added
each time does not exceed this value during resizing, and is added multiple
times to complete the online resizing. The difference is that the metadata
in a flex_bg may be more dispersed.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Antipov <dmantipov@yandex.ru>
[ Upstream commit e416514e309f7e25e577fee45a65f246f67b2261 ]
Since 'rtw89_core_tx_kick_off_and_wait()' assumes timeout
(actually RTW89_ROC_TX_TIMEOUT) in milliseconds, I suppose
that RTW89_ROC_IDLE_TIMEOUT is in milliseconds as well. If
so, 'msecs_to_jiffies()' should be used in a call to
'ieee80211_queue_delayed_work()' from 'rtw89_roc_end()'.
Compile tested only.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shiji Yang <yangshiji66@outlook.com>
[ Upstream commit a11d965a218f0cd95b13fe44d0bcd8a20ce134a8 ]
When a hardware reset is triggered, all registers are reset, so all
queues are forced to stop in hardware interface. However, mac80211
will not automatically stop the queue. If we don't manually stop the
beacon queue, the queue will be deadlocked and unable to start again.
This patch fixes the issue where Apple devices cannot connect to the
AP after calling ieee80211_restart_hw().

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit 7f7c43693c1b46652cfafb7af67ba31726d6ec4e ]
Martin reported that there is a libbpf complaining of non-zero-value tail
padding with LIBBPF_OPTS_RESET macro if struct bpf_netkit_opts is modified
to have a 4-byte tail padding. This only happens to clang compiler.
The commend line is: ./test_progs -t tc_netkit_multi_links
Martin and I did some investigation and found this indeed the case and
the following are the investigation details.
Clang:
clang version 18.0.0
<I tried clang15/16/17 and they all have similar results>
tools/lib/bpf/libbpf_common.h:
#define LIBBPF_OPTS_RESET(NAME, ...) \
do { \
memset(&NAME, 0, sizeof(NAME)); \
NAME = (typeof(NAME)) { \
.sz = sizeof(NAME), \
__VA_ARGS__ \
}; \
} while (0)
#endif
tools/lib/bpf/libbpf.h:
struct bpf_netkit_opts {
/* size of this struct, for forward/backward compatibility */
size_t sz;
__u32 flags;
__u32 relative_fd;
__u32 relative_id;
__u64 expected_revision;
size_t :0;
};
#define bpf_netkit_opts__last_field expected_revision
In the above struct bpf_netkit_opts, there is no tail padding.
prog_tests/tc_netkit.c:
static void serial_test_tc_netkit_multi_links_target(int mode, int target)
{
...
LIBBPF_OPTS(bpf_netkit_opts, optl);
...
LIBBPF_OPTS_RESET(optl,
.flags = BPF_F_BEFORE,
.relative_fd = bpf_program__fd(skel->progs.tc1),
);
...
}
Let us make the following source change, note that we have a 4-byte
tailing padding now.

; link = bpf_program__attach_netkit(skel->progs.tc2, ifindex, &optl);
At -O0 level, the clang compiler creates an intermediate copy.
We have below to store 'flags' with 4-byte store and leave another 4 byte
in the same 8-byte-aligned storage undefined,
5629: c7 85 28 fd ff ff 08 00 00 00 movl $0x8, -0x2d8(%rbp)
and later we store 8-byte to the original zero'ed buffer
5654: 48 8b 85 28 fd ff ff movq -0x2d8(%rbp), %rax
565b: 48 89 45 b0 movq %rax, -0x50(%rbp)
This caused a problem as the 4-byte value at [%rbp-0x2dc, %rbp-0x2e0)
may be garbage.
gcc (gcc 11.4) does not have this issue as it does zeroing struct first before
doing assignments:

It is not clear how to resolve the compiler code generation as the compiler
generates correct code w.r.t. how to handle unnamed padding in C standard.
So this patch changed LIBBPF_OPTS_RESET macro to avoid uninitialized tail
padding. We already knows LIBBPF_OPTS macro works on both gcc and clang,
even with tail padding. So LIBBPF_OPTS_RESET is changed to be a
LIBBPF_OPTS followed by a memcpy(), thus avoiding uninitialized tail padding.
The below is asm code generated with this patch and with clang compiler:
; LIBBPF_OPTS_RESET(optl,
55e3: 48 8d bd 10 fd ff ff leaq -0x2f0(%rbp), %rdi

In the above code, a temporary buffer is zeroed and then has proper value assigned.
Finally, values in temporary buffer are copied to the original variable buffer,
hence tail padding is guaranteed to be 0.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit 100888fb6d8a185866b1520031ee7e3182b173de ]
With latest clang18 (main branch of llvm-project repo), when building bpf selftests,
[~/work/bpf-next (master)]$ make -C tools/testing/selftests/bpf LLVM=1 -j
The following compilation error happens:
fatal error: error in backend: Branch target out of insn range
...
Stack dump:
0. Program arguments: clang -g -Wall -Werror -D__TARGET_ARCH_x86 -mlittle-endian
-I/home/yhs/work/bpf-next/tools/testing/selftests/bpf/tools/include

1. <eof> parser at end of file
2. Code generation
...
The compilation failure only happens to cpu=v2 and cpu=v3. cpu=v4 is okay
since cpu=v4 supports 32-bit branch target offset.
The above failure is due to upstream llvm patch [1] where some inlining behavior
are changed in clang18.
To workaround the issue, previously all 180 loop iterations are fully unrolled.
The bpf macro __BPF_CPU_VERSION__ (implemented in clang18 recently) is used to avoid
unrolling changes if cpu=v4. If __BPF_CPU_VERSION__ is not available and the
compiler is clang18, the unrollng amount is unconditionally reduced.

Refer to Mediatek vendor driver RxDCOC_Calibration() function, when
performing gainfreeze calibration, we should write register 140
instead of 141. This fix can reduce the total calibration time from
6 seconds to 1 second.

[ Upstream commit 4849775587844e44d215289c425bcd70f315efe7 ]
If the net_cls subsystem is already mounted, attempting to mount it again
in setup_classid_environment() will result in a failure with the error code
EBUSY. Despite this, tmpfs will have been successfully mounted at
/sys/fs/cgroup/net_cls. Consequently, the /sys/fs/cgroup/net_cls directory
will be empty, causing subsequent setup operations to fail.
Here's an error log excerpt illustrating the issue when net_cls has already
been mounted at /sys/fs/cgroup/net_cls prior to running
setup_classid_environment():

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit 455a4c46e023ab84263eae0fc7acca9a5ee8b7ac ]
As the vendor DTS files were moved to per-vendor subdirs, there no need
to use common prefixes. Drop the `qcom-' prefix from PMIC dtsi file.
This makes 32-bit qcom/ dts files closer to arm64 ones.

From: HariBabu Gattem <haribabu.gattem@xilinx.com>
[ Upstream commit daed80ed07580e5adc0e6d8bc79933a35154135a ]
When preemption is enabled in kernel and if any task which can be
preempted should not use smp_processor_id() directly, since CPU
switch can happen at any time, the previous value of cpu_id
differs with current cpu_id. As a result we see the below call trace
during xlnx_event_manager_probe.
[ 6.140197] dump_backtrace+0x0/0x190
[ 6.143884] show_stack+0x18/0x40

[ 6.159068] debug_smp_processor_id+0x20/0x2c
[ 6.163453] xlnx_event_manager_probe+0x48/0x250
To protect cpu_id, It is recommended to use get_cpu()/put_cpu()
to disable preemption, get the cpu_id and enable preemption respectively.
(For Reference, Documentation/locking/preempt-locking.rst and
Documentation/kernel-hacking/hacking.rst)
Use preempt_disable()/smp_processor_id()/preempt_enable()
API's to achieve the same.

[ Upstream commit 9c6724abf969251af53cdae525ad8100ec78d3c2 ]
Xen broadcasts SGI to each VM when multiple VMs run on Xen hypervisor. In
such case spurious SGI is expected if one event is registered by one VM and
not registered by another VM. We let users know that Unhandled SGI is not
error and expected if kernel is running on Xen hypervisor.

------------------
From: Justin Tee <justin.tee@broadcom.com>
[ Upstream commit f5779b529240b715f0e358489ad0ed933bf77c97 ]
Because file_name and phba->ModelName are both declared a size 80 bytes,
the extra ".grp" file extension could cause an overflow into file_name.
Define a ELX_FW_NAME_SIZE macro with value 84. 84 incorporates the 4 extra
characters from ".grp". file_name is changed to be declared as a char and
initialized to zeros i.e. null chars.

[ Upstream commit ba2a45a48503665f7e8eeec51f8b40456566b0cd ]
The camera node has both unit address and children within the same bus
mapping, thus needs proper ranges property to fix dtc W=1 warnings:
Warning (unit_address_vs_reg): /soc/camera@11800000: node has a unit name, but no reg or ranges property
Warning (simple_bus_reg): /soc/camera@11800000: missing or empty reg/ranges property
Subtract 0x11800000 from all its children nodes. No functional impact
expected.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit 07e6a553c2f1d385edfc9185081dee442a9dd38d ]
The camera node has both unit address and children within the same bus
mapping, thus needs proper ranges property to fix dtc W=1 warnings:
Warning (unit_address_vs_reg): /soc/camera@fa600000: node has a unit name, but no reg or ranges property
Warning (simple_bus_reg): /soc/camera@fa600000: missing or empty reg/ranges property
Subtract 0xfa600000 from all its children nodes. No functional impact
expected.

In case of no phc we should not return SOFTWARE TIMESTAMPING flags as we do

Remove it from the lan8841_ts_info and simply return 0.

[ Upstream commit 3ed48c80b28d8dcd584d6ddaf00c75b7673e1a05 ]
Spectrum-{1,2,3,4} devices report that a D3hot->D0 transition causes a
reset (i.e., they advertise NoSoftRst-). However, this transition does
not have any effect on the device: It continues to be operational and
network ports remain up. Advertising this support makes it seem as if a
PM reset is viable for these devices. Mark it as unavailable to skip it
when testing reset methods.

------------------
From: Zhengchao Shao <shaozhengchao@huawei.com>
[ Upstream commit d6b83f1e3707c4d60acfa58afd3515e17e5d5384 ]
If failed to allocate "tags" or could not find the final upper device from
start_dev's upper list in bond_verify_device_path(), only the loopback
detection of the current upper device should be affected, and the system is
no need to be panic.
So return -ENOMEM in alb_upper_dev_walk to stop walking, print some warn
information when failed to allocate memory for vlan tags in
bond_verify_device_path.
I also think that the following function calls
netdev_walk_all_upper_dev_rcu
---->>>alb_upper_dev_walk
---------->>>bond_verify_device_path
>From this way, "end device" can eventually be obtained from "start device"
in bond_verify_device_path, IS_ERR(tags) could be instead of
IS_ERR_OR_NULL(tags) in alb_upper_dev_walk.

From: Jose Ignacio Tornos Martinez <jtornosm@redhat.com>
[ Upstream commit d2689b6a86b9d23574bd4b654bf770b6034e2c7e ]
The device is always reset two consecutive times (ax88179_reset is called
twice), one from usbnet_probe during the device binding and the other from
usbnet_open.
Remove the non-necessary reset during the device binding and let the reset
operation from open to keep the normal behavior (tested with generic ASIX
Electronics Corp. AX88179 Gigabit Ethernet device).

From: Alexander Stein <alexander.stein@ew.tq-group.com>
[ Upstream commit 0d4ac04fa7c3f6dc263dba6f575a2ec7a2d4eca8 ]
imx7d uses two ports for 'in-ports', so the syntax port@<num> has to
be used. imx7d has both port and port@1 nodes present, raising these
error:
funnel@30041000: in-ports: More than one condition true in oneOf schema
funnel@30041000: Unevaluated properties are not allowed
('in-ports' was unexpected)
Fix this by also using port@0 for imx7s as well.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
[ Upstream commit b16904fd9f01b580db357ef2b1cc9e86d89576c2 ]
With latest upstream llvm18, the following test cases failed:
$ ./test_progs -j
#13/2 bpf_cookie/multi_kprobe_link_api:FAIL
#13/3 bpf_cookie/multi_kprobe_attach_api:FAIL
#13 bpf_cookie:FAIL
#77 fentry_fexit:FAIL
#78/1 fentry_test/fentry:FAIL
#78 fentry_test:FAIL
#82/1 fexit_test/fexit:FAIL
#82 fexit_test:FAIL
#112/1 kprobe_multi_test/skel_api:FAIL
#112/2 kprobe_multi_test/link_api_addrs:FAIL
[...]
#112 kprobe_multi_test:FAIL
#356/17 test_global_funcs/global_func17:FAIL
#356 test_global_funcs:FAIL
Further analysis shows llvm upstream patch [1] is responsible for the above
failures. For example, for function bpf_fentry_test7() in net/bpf/test_run.c,
without [1], the asm code is:
0000000000000400 <bpf_fentry_test7>:
400: f3 0f 1e fa endbr64
404: e8 00 00 00 00 callq 0x409 <bpf_fentry_test7+0x9>
409: 48 89 f8 movq %rdi, %rax
40c: c3 retq
40d: 0f 1f 00 nopl (%rax)
... and with [1], the asm code is:
0000000000005d20 <bpf_fentry_test7.specialized.1>:
5d20: e8 00 00 00 00 callq 0x5d25 <bpf_fentry_test7.specialized.1+0x5>
5d25: c3 retq
... and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7>
and this caused test failures for #13/#77 etc. except #356.
For test case #356/17, with [1] (progs/test_global_func17.c)), the main prog
looks like:
0000000000000000 <global_func17>:
0: b4 00 00 00 2a 00 00 00 w0 = 0x2a
1: 95 00 00 00 00 00 00 00 exit
... which passed verification while the test itself expects a verification
failure.
Let us add 'barrier_var' style asm code in both places to prevent function
specialization which caused selftests failure.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Minsuk Kang <linuxlovemin@yonsei.ac.kr>
[ Upstream commit 2adc886244dff60f948497b59affb6c6ebb3c348 ]
Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug
occurs when txs->cnt, data from a URB provided by a USB device, is
bigger than the size of the array txs->txstatus, which is
HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug
handling code after the check. Make the function return if that is the
case.
Found by a modified version of syzkaller.
UBSAN: array-index-out-of-bounds in htc_drv_txrx.c
index 13 is out of range for type '__wmi_event_txstatus [12]'
Call Trace:

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Baochen Qiang <quic_bqiang@quicinc.com>
[ Upstream commit 5082b3e3027eae393a4e86874bffb4ce3f83c26e ]
We are seeing below error randomly in the case where only
one MSI vector is configured:
kernel: ath11k_pci 0000:03:00.0: wmi command 16387 timeout
The reason is, currently, in ath11k_pcic_ext_irq_enable(),
ATH11K_FLAG_EXT_IRQ_ENABLED is set before NAPI is enabled.
This results in a race condition: after
ATH11K_FLAG_EXT_IRQ_ENABLED is set but before NAPI enabled,
CE interrupt breaks in. Since IRQ is shared by CE and data
path, ath11k_pcic_ext_interrupt_handler() is also called
where we call disable_irq_nosync() to disable IRQ. Then
napi_schedule() is called but it does nothing because NAPI
is not enabled at that time, meaning
ath11k_pcic_ext_grp_napi_poll() will never run, so we have
no chance to call enable_irq() to enable IRQ back. Finally
we get above error.
Fix it by setting ATH11K_FLAG_EXT_IRQ_ENABLED after all
NAPI and IRQ work are done. With the fix, we are sure that
by the time ATH11K_FLAG_EXT_IRQ_ENABLED is set, NAPI is
enabled.
Note that the fix above also introduce some side effects:
if ath11k_pcic_ext_interrupt_handler() breaks in after NAPI
enabled but before ATH11K_FLAG_EXT_IRQ_ENABLED set, nothing
will be done by the handler this time, the work will be
postponed till the next time the IRQ fires.

------------------
From: Po-Hao Huang <phhuang@realtek.com>
[ Upstream commit 0052b3c401cdf39d3c3d12a0c3852175bc9a39c7 ]
The attempt to enter power save mode might fail if there are still
beacons pending in the queue. This sometimes happens after stopping
P2P GO or AP mode. Extend stop AP function and flush all beacons to
resolve this.

From: Chih-Kang Chang <gary.chang@realtek.com>
[ Upstream commit 756b31203d482d2dd1aa6c208978b0410dc7530f ]
In concurrent mode, when STA interface is scanning, it causes
AP interface TX beacon on wrong channel. We modified it to scan
with the operating channel when one of the interfaces is already
connected. Additionally, STA interface need to stop scan when AP
interface is starting to avoid TX beacon on wrong channel. Finally,
AP interface need to stop TX beacon when STA interface is scanning
and switching to non-OP channel,This prevent other device to get
beacons on wrong channel.

------------------
From: Hou Tao <houtao1@huawei.com>
[ Upstream commit 79d93b3c6ffd79abcd8e43345980aa1e904879c4 ]
Both map deletion operation, map release and map free operation use
fd_array_map_delete_elem() to remove the element from fd array and
need_defer is always true in fd_array_map_delete_elem(). For the map
deletion operation and map release operation, need_defer=true is
necessary, because the bpf program, which accesses the element in fd
array, may still alive. However for map free operation, it is certain
that the bpf program which owns the fd array has already been exited, so
setting need_defer as false is appropriate for map free operation.
So fix it by adding need_defer parameter to bpf_fd_array_map_clear() and
adding a new helper __fd_array_map_delete_elem() to handle the map
deletion, map release and map free operations correspondingly.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kang Yang <quic_kangyang@quicinc.com>
[ Upstream commit ed7e818a7b501012038d6bc6fedadaf7375a380a ]
For AP mode, the peer is created earlier in ath12k_mac_op_add_interface() but
ath12k_mac_op_assign_vif_chanctx() will try to create peer again. Then an
error will return which makes AP mode startup fail.
Kernel log:
[ 5017.665006] ath12k_pci 0000:04:00.0: failed to create peer after vdev start delay: -22
wpa_supplicant log:
Failed to set beacon parameters
Interface initialization failed
wls1: interface state UNINITIALIZED->DISABLED
wls1: AP-DISABLED
wls1: Unable to setup interface.
Failed to initialize AP interface
wls1: interface state DISABLED->DISABLED
wls1: AP-DISABLED
So fix this check and enable AP mode for WCN7850, as now AP mode works normally.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hannes Reinecke <hare@suse.de>
[ Upstream commit b57c4db5d23b9df0118a25e2441c9288edd73710 ]
The current FC error recovery is sending up to three REC (recovery) frames
in 10 second intervals, and as a final step sending an ABTS after 30
seconds for the command itself. Unfortunately sending an ABTS is also the
action for the SCSI abort handler, and the default timeout for SCSI
commands is also 30 seconds. This causes two ABTS to be scheduled, with the
libfc one slightly earlier. The ABTS scheduled by SCSI EH then sees the
command to be already aborted, and will always return with a 'GOOD' status
irrespective on the actual result from the first ABTS. This causes the
SCSI EH abort handler to always succeed, and SCSI EH never to be engaged.
Fix this by not issuing an ABTS when a SCSI command is present for the
exchange, but rather wait for the abort scheduled from SCSI EH. And warn
if an abort is already scheduled to avoid similar errors in the future.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tobias Waldekranz <tobias@waldekranz.com>
[ Upstream commit 7dd12fe34686d89c332b1a05104d18d728591f0a ]
Before this change, when operating in polled mode, i.e. no IRQ is
available, every individual C45 access would be hit with a 150us sleep
after the bus access.
For example, on a board with a CN9130 SoC connected to an MV88X3310
PHY, a single C45 read would take around 165us:
root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003
Performed 1000 reads in 165ms
By replacing the long sleep with a tighter poll loop, we observe a 10x
increase in bus throughput:
root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003
Performed 1000 reads in 15ms

the BSS is in HE mode, while the FW thinks it is in EHT mode.

From: Hou Tao <houtao1@huawei.com>
[ Upstream commit 06e5c999f10269a532304e89a6adb2fbfeb0593c ]
generic_map_{delete,update}_batch() doesn't set uattr->batch.count as
zero before it tries to allocate memory for key. If the memory
allocation fails, the value of uattr->batch.count will be incorrect.
Fix it by setting uattr->batch.count as zero beore batched update or
deletion.

------------------
From: Dmitry Antipov <dmantipov@yandex.ru>
[ Upstream commit fe0a7776d4d19e613bb8dd80fe2d78ae49e8b49d ]
Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()'
should check the return value before examining skb data. So convert
the latter to return an appropriate error code and propagate it to
return from 'wfx_start_ap()' as well. Compile tested only.

From: Lingbo Kong <quic_lingbok@quicinc.com>
[ Upstream commit 7133b072dfbfac8763ffb017642c9c894894c50d ]
We observe some packets are discarded in ieee80211_rx_handlers_result
function for WCN7850. This is because the way to get multicast/broadcast
indicator with RX_MSDU_END_INFO5_DA_IS_MCBC & info5 is incorrect. It should
use RX_MSDU_END_INFO13_MCAST_BCAST & info13 to get multicast/broadcast
indicator.

[ Upstream commit 24f110240c03c6b5368f1203bac72883d511e606 ]
Don't rely on the PCI memory for the devcmd opcode because we
read a 0xff value if the PCI bus is broken, which can cause us
to report a bogus dev_cmd opcode later.

------------------
From: Shannon Nelson <shannon.nelson@amd.com>
[ Upstream commit ca5fdf9a7c5b65968c718f2be159cda4c13556a1 ]
If the driver or firmware is stuck in reset state, don't bother
trying to use adminq commands. This speeds up shutdown and
prevents unnecessary timeouts and error messages.
This includes a bit of rework on ionic_adminq_post_wait()
and ionic_adminq_post_wait_nomsg() to both use
__ionic_adminq_post_wait() which can do the checks needed in
both cases.

there was a risk of truncation when copying it and a second string
into "full_path" since it was also PATH_MAX sized. The W=1 builds were

To fix this, unconditionally check for truncation (as was already done
for the case where "%SESSNAME%" was present).

------------------
From: Michal Simek <michal.simek@amd.com>
[ Upstream commit 6a10a19a6bd2fd8d27a510678bf87bd9408f51d8 ]
fixed clock nodes can't be on the bus because they are missing reg
property. That's why move them to root.
And because it is root it is good to have it as the first node in a file.

From: Fabio Estevam <festevam@denx.de>
[ Upstream commit e3aa1a82fb20ee97597022f6528823a8ab82bde6 ]
The 'gpios' property to describe the SDA and SCL GPIOs is considered
deprecated according to i2c-gpio.yaml.
Switch to the preferred 'sda-gpios' and 'scl-gpios' properties.
This fixes the following schema warnings:
imx23-sansa.dtb: i2c-0: 'sda-gpios' is a required property
from schema $id: http://devicetree.org/schemas/i2c/i2c-gpio.yaml#

Fix by calling lpfc_reinit_vmid and copying the physical port's vmid_flag
to the NPIV's vmid_flag in the NPIV registration cmpl code path.

From: Justin Tee <justin.tee@broadcom.com>
[ Upstream commit aba0fb0ef607a71511d23a07406f11130c1a54c5 ]
If priority tagging is set in the service parameters of a FLOGI cmpl, then
we update the vmid_flag. In the current logic, if a follow up FLOGI cmpl
updates its service parameters such that priority tagging is no longer set,
then the vmid_flag ends up keeping stale data.
Fix by ensuring we clear the vmid_flag member during lpfc_reinit_vmid, and
check the priority tagging service parameter after reinitialization of the
vmid data structures.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yihang Li <liyihang9@huawei.com>
[ Upstream commit ce26497c745d0541aec930d5211b431a1c26af97 ]
Currently in directly attached scenario, the phyup event
HISI_PHYE_PHY_UP_PM is notified before .phy_attached is set - this may
cause the phyup work hisi_sas_bytes_dmaed() execution failed and the
attached device will not be found.
To fix it, set .phy_attached before notifing phyup event.

------------------
From: Ahmed Zaki <ahmed.zaki@intel.com>
[ Upstream commit 20f73b60bb5c276cee9b1a530f100c677bc74af8 ]
Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.
Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX
for consistency.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Igor Russkikh <irusskikh@marvell.com>
[ Upstream commit b3cb7a830a24527877b0bc900b9bd74a96aea928 ]
Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.
This simplifies error handling and eliminates aq_ring_free
on higher layer.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tobias Waldekranz <tobias@waldekranz.com>
[ Upstream commit fc82a08ae795ee6b73fb6b50785f7be248bec7b5 ]
mv88e6xxx_get_stats, which collects stats from various sources,
expects all callees to return the number of stats read. If an error
occurs, 0 should be returned.
Prevent future mishaps of this kind by updating the return type to
reflect this contract.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Walleij <linus.walleij@linaro.org>
[ Upstream commit 6e75ac5a824e1551764cd4bfce5ede3d5fafc407 ]
Fix some errors in the Marvell MV88E6xxx switch descriptions:
- The top node had no address size or cells.
- switch0@0 is not OK, should be ethernet-switch@0.
- The ports node should be named ethernet-ports
- The ethernet-ports node should have port@0 etc children, no
plural "ports" in the children.
- Ports should be named ethernet-port@0 etc
- PHYs should be named ethernet-phy@0 etc
This serves as an example of fixes needed for introducing a
schema for the bindings, but the patch can simply be applied.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Walleij <linus.walleij@linaro.org>
[ Upstream commit fedb923aaf611e36adad4cd8c91d35bc283d3eea ]
Fix some errors in the Marvell MV88E6xxx switch descriptions:
- The top node had no address size or cells.
- switch0@0 is not OK, should be ethernet-switch@0.
- ports should be ethernet-ports
- port@0 should be ethernet-port@0
- PHYs should be named ethernet-phy@

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Lyakas <alex.lyakas@zadara.com>
[ Upstream commit dc1cc22ed58f11d58d8553c5ec5f11cbfc3e3039 ]
Upon assembling the array, both kernel and mdadm allow the devices to have event
counter difference of 1, and still consider them as up-to-date.
However, a device whose event count is behind by 1, may in fact not be up-to-date,
and array resync with such a device may cause data corruption.
To avoid this, consult the superblock of the freshest device about the status
of a device, whose event counter is behind by 1.

As per the earlier patches, BPF sub-programs have bpf_callback_t
signature and CFI expects callers to have matching signature. This is
violated by bpf_prog_aux::bpf_exception_cb().

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mao Jinlong <quic_jinlmao@quicinc.com>
[ Upstream commit bdb6339fd46b8702ea7411b0b414587b86a40562 ]
When a node is only one in port or one out port, address-cells and
size-cells are not required in in-ports and out-ports. And the number
and reg of the port need to be removed.

From: Jesse Brandeburg <jesse.brandeburg@intel.com>
[ Upstream commit 3314f2097dee43defc20554f961a8b17f4787e2d ]
This series is introducing the use of FIELD_GET and FIELD_PREP which
requires bitfield.h to be included. Fix all the includes in this one
change, and rearrange includes into alphabetical order to ease
readability and future maintenance.
virtchnl.h and it's usage was modified to have it's own includes as it
should. This required including bits.h for virtchnl.h.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jesse Brandeburg <jesse.brandeburg@intel.com>
[ Upstream commit 7173be21ae29ef50ada42fd4464056a9d3f55bb3 ]
While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.
Do the same for the VLAN EMODE defines as well.

------------------
From: Benjamin Berg <benjamin.berg@intel.com>
[ Upstream commit 32af9a9e1069e55bc02741fb00ac9d0ca1a2eaef ]
This is a more of a cosmetic fix. The branch will only be taken if
proberesp_ies is set, which implies that beacon_ies is not set unless we
are connected to an AP that just did a channel switch. And, in that case
we should have found the BSS in the internal storage to begin with.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Iulia Tanasescu <iulia.tanasescu@nxp.com>
[ Upstream commit 9f150019f176078144b02c4b9b9dbe7fd5a2fcc3 ]
When a PA sync socket is closed, the associated hcon is also unlinked
and cleaned up. If there are no other hcons marked with the
HCI_CONN_PA_SYNC flag, HCI_OP_LE_PA_TERM_SYNC is sent to controller.
Between the time of the command and the moment PA sync is terminated
in controller, residual BIGInfo reports might continue to come.
This causes a new PA sync hcon to be added, and a new socket to be
notified to user space.
This commit fixs this by adding a flag on a Broadcast listening
socket to mark when the PA sync child has been closed.
This flag is checked when BIGInfo reports are indicated in
iso_connect_ind, to avoid recreating a hcon and socket if
residual reports arrive before PA sync is terminated.

From: Wen Gu <guwen@linux.alibaba.com>
[ Upstream commit c6b8b8eb49904018e22e4e4b1fa502e57dc747d9 ]
The system EID (SEID) is an internal EID used by SMC-D to represent the
s390 physical machine that OS is executing on. On s390 architecture, it
predefined by fixed string and part of cpuid and is enabled regardless
of whether underlay device is virtual ISM or platform firmware ISM.
However on non-s390 architectures where SMC-D can be used with virtual
ISM devices, there is no similar information to identify physical
machines, especially in virtualization scenarios. So in such cases, SEID
is forcibly disabled and the user-defined UEID will be used to represent
the communicable space.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lin Ma <linma@zju.edu.cn>
[ Upstream commit c2b2ee36250d967c21890cb801e24af4b6a9eaa5 ]
It appears that there is a typo in the code where the nlattr array is
being parsed with policy br_cfm_cc_ccm_tx_policy, but the instance is
being accessed via IFLA_BRIDGE_CFM_CC_RDI_INSTANCE, which is associated
with the policy br_cfm_cc_rdi_policy.
This problem was introduced by commit 2be665c3940d ("bridge: cfm: Netlink
SET configuration Interface.").
Though it seems like a harmless typo since these two enum owns the exact
same value (1 here), it is quite misleading hence fix it by using the
correct enum IFLA_BRIDGE_CFM_CC_CCM_TX_INSTANCE here.

From: Andrii Staikov <andrii.staikov@intel.com>
[ Upstream commit 31deb12e85c35ddd2c037f0107d05d8674cab2c0 ]
Currently, if a VF is disabled using the
'ip link set dev $ETHX vf $VF_NUM state disable' command, the VF is still
able to receive traffic.
Fix the behavior of the 'ip link set dev $ETHX vf $VF_NUM state disable'
to completely shutdown the VF's queues making it entirely disabled and
not able to receive or send any traffic.
Modify the behavior of the 'ip link set $ETHX vf $VF_NUM state enable'
command to make a VF do reinitialization bringing the queues back up.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vladimir Oltean <vladimir.oltean@nxp.com>
[ Upstream commit 68e1010cda7967cfca9c8650ee1f4efcae54ab90 ]
of_get_child_by_name() gives us an OF node with an elevated refcount,
which should be dropped when we're done with it. This is so that,
if (of_node_check_flag(node, OF_DYNAMIC)) is true, the node's memory can
eventually be freed.
There are 2 distinct paths to be considered in qca8k_mdio_register():
- devm_of_mdiobus_register() succeeds: since commit 3b73a7b8ec38 ("net:
mdio_bus: add refcounting for fwnodes to mdiobus"), the MDIO core
treats this well.
- devm_of_mdiobus_register() or anything up to that point fails: it is
the duty of the qca8k driver to release the OF node.
This change addresses the second case by making sure that the OF node
reference is not leaked.
The "mdio" node may be NULL, but of_node_put(NULL) is safe.

Let's check return value of f2fs_reserve_new_block() in do_recover_data()
rather than letting it fails silently.
Also refactoring check condition on return value of f2fs_reserve_new_block()
as below:
- trigger f2fs_bug_on() only for ENOSPC case;
- use do-while statement to avoid redundant codes;

From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit 26257869672fd4a06a60c2da841e15fb2cb47bbe ]
In a couple of loops over the all streams, we check the bitmap against
the loop counter. A more correct reference would be, however, the
index of each stream, instead.
This patch corrects the check of bitmaps to the stream index.
Note that this change doesn't fix anything for now; all existing
drivers set up the stream indices properly, hence the loop count is
always equal with the stream index. That said, this change is only
for consistency.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Al Viro <viro@zeniv.linux.org.uk>
[ Upstream commit 504e08cebe1d4e1efe25f915234f646e74a364a8 ]
If refcount is less than 1, we should just warn, unlock dentry and
return true, so that the caller doesn't try to do anything else.
Taking care of that leaves the rest of "lockref_put_return() has
failed" case equivalent to "decrement refcount and rejoin the
normal slow path after the point where we grab ->d_lock".
NOTE: lockref_put_return() is strictly a fastpath thing - unlike
the rest of lockref primitives, it does not contain a fallback.
Caller (and it looks like fast_dput() is the only legitimate one
in the entire kernel) has to do that itself. Reasons for
lockref_put_return() failures:
* ->d_lock held by somebody
* refcount <= 0
* ... or an architecture not supporting lockref use of
cmpxchg - sparc, anything non-SMP, config with spinlock debugging...
We could add a fallback, but it would be a clumsy API - we'd have
to distinguish between:
(1) refcount > 1 - decremented, lock not held on return
(2) refcount < 1 - left alone, probably no sense to hold the lock
(3) refcount is 1, no cmphxcg - decremented, lock held on return
(4) refcount is 1, cmphxcg supported - decremented, lock *NOT* held
on return.
We want to return with no lock held in case (4); that's the whole point of that
thing. We very much do not want to have the fallback in case (3) return without
a lock, since the caller might have to retake it in that case.
So it wouldn't be more convenient than doing the fallback in the caller and
it would be very easy to screw up, especially since the test coverage would
suck - no way to test (3) and (4) on the same kernel build.

------------------
From: Jan Kara <jack@suse.cz>
[ Upstream commit 9d618d19b29c2943527e3a43da0a35aea91062fc ]
The VFS will not be locking moved directory if its parent does not
change. Change ocfs2 rename code to avoid touching renamed directory if
its parent does not change as without locking that can corrupt the
filesystem.

From: Danylo Piliaiev <dpiliaiev@igalia.com>
[ Upstream commit 07e6de738aa6f0e873463e9ca88bdb7081c4bfd4 ]
KGSL doesn't support a690 so all reg values were the same as
on a660. Now we know the values and they are different from the
windows driver.
This fixes hangs on D3D12 games and some CTS tests.

From: Nicholas Susanto <nicholas.susanto@amd.com>
[ Upstream commit 2ce156482a6fef349d2eba98e5070c412d3af662 ]
[Why]
When switching to another HDMI mode, we are unnecesarilly
disabling/enabling FIFO causing both HPO and DIG registers to be set at
the same time when only HPO is supposed to be set.
This can lead to a system hang the next time we change refresh rates as
there are cases when we don't disable OTG/FIFO but FIFO is enabled when
it isn't supposed to be.
[How]
Removing the enable/disable FIFO entirely.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wenjing Liu <wenjing.liu@amd.com>
[ Upstream commit 08a32addf17317b9fac55be9b31275cbf6e41fb7 ]
Current implementation will choose to use refclk as dscclk. This is not
recommended by hardware team as refclk is a fixed value which could
cause unnecessary power consumption or it could be not enough for large
DSC timings. So we are adding new interfaces so we could switch to use
dynamically generated DSCCLK by DTO. So DSCCLK is programmable based on
current pixel clock and dispclk.

'supported_status' is only set in one code path. I'm not familiar with
the code to say if that path will always be ran in real life, but
whether that is the case or not, I think it is good to initialize
'supported_status' to 0 to silence the warning (and possibly fix a bug).

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 90d50b8d85834e73536fdccd5aa913b30494fef0 ]
It's been reported that DSI host driver's detach can be called without
the attach ever happening:
https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/
After reading the code, I think this is what happens:
We have a DSI host defined in the device tree and a DSI peripheral under
that host (i.e. an i2c device using the DSI as data bus doesn't exhibit
this behavior).
The host driver calls mipi_dsi_host_register(), which causes (via a few
functions) mipi_dsi_device_add() to be called for the DSI peripheral. So
now we have a DSI device under the host, but attach hasn't been called.
Normally the probing of the devices continues, and eventually the DSI
peripheral's driver will call mipi_dsi_attach(), attaching the
peripheral.
However, if the host driver's probe encounters an error after calling
mipi_dsi_host_register(), and before the peripheral has called
mipi_dsi_attach(), the host driver will do cleanups and return an error
from its probe function. The cleanups include calling
mipi_dsi_host_unregister().
mipi_dsi_host_unregister() will call two functions for all its DSI
peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister().
The latter makes sense, as the device exists, but the former may be
wrong as attach has not necessarily been done.
To fix this, track the attached state of the peripheral, and only detach
from mipi_dsi_host_unregister() if the peripheral was attached.
Note that I have only tested this with a board with an i2c DSI
peripheral, not with a "pure" DSI peripheral.
However, slightly related, the unregister machinery still seems broken.
E.g. if the DSI host driver is unbound, it'll detach and unregister the
DSI peripherals. After that, when the DSI peripheral driver unbound
it'll call detach either directly or using the devm variant, leading to
a crash. And probably the driver will crash if it happens, for some
reason, to try to send a message via the DSI bus.
But that's another topic.

printk, it is now replaced with printk_ratelimited.

------------------
From: Michael Tretter <m.tretter@pengutronix.de>
[ Upstream commit 9e7dc39260edac180c206bb6149595a40eabae3e ]
When using 32 bit RGB formats, the RGA on the rk3568 produces wrong
colors as the wrong color channels are read or written. The reason is
that the format description for the channel swizzeling is wrong and the
wrong bits are configured. For example, when converting ARGB32 to NV12,
the alpha channel is used as blue channel.. This doesn't happen if the
color format is the same on both sides.
Fix the color_swap settings of the formats to correctly handle 32 bit
RGB formats.
For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an
effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus,
it is removed from the list of supported formats.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74 ]
In all known platforms the ISP has dedicated IRQ lines, but for some
reason the driver uses IRQF_SHARED.
Supporting IRQF_SHARED properly requires handling interrupts even when
our device is disabled, and the driver does not handle this. To avoid
adding such code, and to be sure the driver won't accidentally be used
in a platform with shared interrupts, let's drop the IRQF_SHARED flag.

[ Upstream commit 3eb7910e1b16a2c136be26a8380f21469225b2f6 ]
The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.
Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
[ Upstream commit 870565f063a58576e8a4529f122cac4325c6b395 ]
In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.
This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.
It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
[ Upstream commit efa28efd9cba015f8c3d88123527c3c3cfcd13d0 ]
Supported media bus codes on the resizer sink pad are identical to the
ISP source pad. The .enum_mbus_code() handler thus delegates the
enumeration to the ISP's operation. This is problematic for two
reasons:
- Format enumeration on the ISP source pad is dependent on the format
configured on the ISP sink pad for the same subdev state (TRY or
ACTIVE), while format enumeration on the resizer sink pad should
return all formats supported by the resizer subdev, regardless of the
ISP configuration.
- Delegating the operation involves creating a fake v4l2_subdev_state on
the stack to pass to the ISP .enum_mbus_code() handler. This gets in
the way of evolution of both the ISP enumeration handler and, more
generally, the V4L2 subdev state infrastructure.
Fix those two issues by implementing format enumeration manually for the
resizer.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: James Seo <james@equiv.tech>
[ Upstream commit c9ba592580947b81f33f514320aeef02ddc001fd ]
The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its
BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is
evidently a valid way of representing a WMI data item as far as the
Microsoft ACPI-WMI mapper is concerned, but is preventing the driver from
loading.
This seems quite rare, but add support for such strings. Treating this as a
quirk pretty much means adding that support anyway.
Also clean up an oversight in update_numeric_sensor_from_wobj() in which
the result of hp_wmi_strdup() was being used without error checking.

------------------
From: Chao Yu <chao@kernel.org>
[ Upstream commit 4961acdd65c956e97c1a000c82d91a8c1cdbe44b ]
It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.
Similar issue was fixed by commit 2d1fe8a86bf5 ("f2fs: fix to tag
gcing flag on page during file defragment").

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit 16ac5b21b31b439f03cdf44c153c5f5af94fb3eb ]
Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time
and at driver unbind time. Among other things, this means that if a
panel is in use that it won't be cleanly powered off at system
shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart and at driver remove (or unbind) time comes
straight out of the kernel doc "driver instance overview" in
drm_drv.c.
A few notes about this fix:
- When adding drm_atomic_helper_shutdown() to the unbind path, I added
it after drm_kms_helper_poll_fini() since that's when other drivers
seemed to have it.
- Technically with a previous patch, ("drm/atomic-helper:
drm_atomic_helper_shutdown(NULL) should be a noop"), we don't
actually need to check to see if our "drm" pointer is NULL before
calling drm_atomic_helper_shutdown(). We'll leave the "if" test in,
though, so that this patch can land without any dependencies. It
could potentially be removed later.
- This patch also makes sure to set the drvdata to NULL in the case of
bind errors to make sure that shutdown can't access freed data.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Vacek <neelx@redhat.com>
[ Upstream commit 4f973e211b3b1c6d36f7c6a19239d258856749f9 ]
Releasing the `priv->lock` while iterating the `priv->multicast_list` in
`ipoib_mcast_join_task()` opens a window for `ipoib_mcast_dev_flush()` to
remove the items while in the middle of iteration. If the mcast is removed
while the lock was dropped, the for loop spins forever resulting in a hard
lockup (as was reported on RHEL 4.18.0-372.75.1.el8_6 kernel):
Task A (kworker/u72:2 below) | Task B (kworker/u72:0 below)
-----------------------------------+-----------------------------------
ipoib_mcast_join_task(work) | ipoib_ib_dev_flush_light(work)
spin_lock_irq(&priv->lock) | __ipoib_ib_dev_flush(priv, ...)

&priv->multicast_list, list) |

| list_add_tail(&mcast->list, &remove_list)
| spin_unlock_irqrestore(&priv->lock, flags)
spin_lock_irq(&priv->lock) |
| ipoib_mcast_remove_list(&remove_list)
(Here, `mcast` is no longer on the | list_for_each_entry_safe(mcast, tmcast,
`priv->multicast_list` and we keep | remove_list, list)
spinning on the `remove_list` of | >>> wait_for_completion(&mcast->done)
the other thread which is blocked |
and the list is still valid on |
it's stack.)
Fix this by keeping the lock held and changing to GFP_ATOMIC to prevent
eventual sleeps.
Unfortunately we could not reproduce the lockup and confirm this fix but
based on the code review I think this fix should address such lockups.

cmd has a monotonically increasing id, and cmds are executed
sequentially, so we can check the id of the last reponsed cmd, then
determine whether a command has been responded or not.

From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 3735228bbe3511f844e03dfcc4003fadb59dde23 ]
HTS must be more then width, so the 1080 value clearly is wrong,
this is then corrected with some weird math dividing clocks in
to_pixels_per_line() which results in the hts getting multiplied by 2,
resulting in 2160.
Instead just directly set hts to the correct value of 2160 and
drop to_pixels_per_line().

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alvin Lee <alvin.lee2@amd.com>
[ Upstream commit dd4e4bb28843393065eed279e869fac248d03f0f ]
[Description]
For mode programming we want to extend the prefetch as much as possible
(up to oto, or as long as we can for equ) if we're not already applying
the 60us prefetch requirement. This is to avoid intermittent underflow
issues during prefetch.
The prefetch extension is applied under the following scenarios:
1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank)
2. We're using subvp or drr methods of p-state switch, in which case we
we don't care if prefetch takes up more of the blanking time
Mode programming typically chooses the smallest prefetch time possible
(i.e. highest bandwidth during prefetch) presumably to create margin between
p-states / c-states that happen in vblank and prefetch. Therefore we only
apply this prefetch extension when p-state in vblank is not required (UCLK
p-states take up the most vblank time).

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

From: Alvin Lee <alvin.lee2@amd.com>
[ Upstream commit 9a902a9073c287353e25913c0761bfed49d75a88 ]
[Description]
- When we're in a no plane config, DCN is always asserting
P-State allow
- This creates a scenario where the P-State blackout can start
just as VUPDATE takes place and transitions the DCN config to
a one where one or more HUBP's are active which can result in
underflow
- To fix this issue, force p-state disallow and unforce after
the transition from no planes case -> one or more planes active

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonathan Kim <jonathan.kim@amd.com>
[ Upstream commit bd33bb1409b494558a2935f7bbc7842def957fcd ]
MES provides the driver a call to explicitly flush stale process memory
within the MES to avoid a race condition that results in a fatal
memory violation.
When SET_SHADER_DEBUGGER is called, the driver passes a memory address
that represents a process context address MES uses to keep track of
future per-process calls.
Normally, MES will purge its process context list when the last queue
has been removed. The driver, however, can call SET_SHADER_DEBUGGER
regardless of whether a queue has been added or not.
If SET_SHADER_DEBUGGER has been called with no queues as the last call
prior to process termination, the passed process context address will
still reside within MES.
On a new process call to SET_SHADER_DEBUGGER, the driver may end up
passing an identical process context address value (based on per-process
gpu memory address) to MES but is now pointing to a new allocated buffer
object during KFD process creation. Since the MES is unaware of this,
access of the passed address points to the stale object within MES and
triggers a fatal memory violation.
The solution is for KFD to explicitly flush the process context address
from MES on process termination.
Note that the flush call and the MES debugger calls use the same MES
interface but are separated as KFD calls to avoid conflicting with each
other.

For YUV cases, setting the required format bits was missed
out in the register programming. Lets fix it now in preparation
of adding YUV formats support for writeback.
changes in v2:

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paloma Arellano <quic_parellan@quicinc.com>
[ Upstream commit 45284ff733e4caf6c118aae5131eb7e7cf3eea5a ]
Add a mutex lock to control vblank irq to synchronize vblank
enable/disable operations happening from different threads to prevent
race conditions while registering/unregistering the vblank irq callback.
v4: -Removed vblank_ctl_lock from dpu_encoder_virt, so it is only a
parameter of dpu_encoder_phys.
-Switch from atomic refcnt to a simple int counter as mutex has
now been added
v3: Mistakenly did not change wording in last version. It is done now.
v2: Slightly changed wording of commit message

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang, Beyond <Wang.Beyond@amd.com>
[ Upstream commit 94aeb4117343d072e3a35b9595bcbfc0058ee724 ]
Issue: during evict or validate happened on amdgpu_bo, the 'from' and
'to' is always same in ftrace event of amdgpu_bo_move
where calling the 'trace_amdgpu_bo_move', the comment says move_notify
is called before move happens, but actually it is called after move
happens, here the new_mem is same as bo->resource
Fix: move trace_amdgpu_bo_move from move_notify to amdgpu_bo_move

From: Kuan-Wei Chiu <visitorckw@gmail.com>
[ Upstream commit bfbea9e5667cfa9552c3d88f023386f017f6c308 ]
In cases where kcalloc() fails for the 'clk_data->clks' allocation, the
code path does not handle the failure gracefully, potentially leading
to a memory leak. This fix ensures proper cleanup by freeing the
allocated memory for 'clk_data' before returning.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Werner Fischer <devlists@wefi.net>
[ Upstream commit d12971849d71781c1e4ffd1117d4878ce233d319 ]
WDTCTRL bit 3 sets the mode choice for the clock input of IT8784/IT8786.
Some motherboards require this bit to be set to 1 (= PCICLK mode),
otherwise the watchdog functionality gets broken. The BIOS of those
motherboards sets WDTCTRL bit 3 already to 1.
Instead of setting all bits of WDTCTRL to 0 by writing 0x00 to it, keep
bit 3 of it unchanged for IT8784/IT8786 chips. In this way, bit 3 keeps
the status as set by the BIOS of the motherboard.
Watchdog tests have been successful with this patch with the following
systems:
IT8784: Thomas-Krenn LES plus v2 (YANLING YL-KBRL2 V2)
IT8786: Thomas-Krenn LES plus v3 (YANLING YL-CLU L2)
IT8786: Thomas-Krenn LES network 6L v2 (YANLING YL-CLU6L)

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alvin Lee <alvin.lee2@amd.com>
[ Upstream commit dff45f03f508c92cd8eb2050e27b726726b8ae0b ]
[Description]
There is a corner case where the symclk otg flag is cleared
when disabling the phantom pipe for subvp (because the phantom
and main pipe share the same link). This is undesired because
we need the maintain the correct symclk otg flag state for
the main pipe.
For now only clear the flag only for HDMI signal type, since
it's only set for HDMI signal type (phantom is virtual). The
ideal solution is to not clear it if the stream is phantom but
currently there's a bug that doesn't allow us to do this. Once
this issue is fixed the proper fix can be implemented.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuan-Wei Chiu <visitorckw@gmail.com>
[ Upstream commit 21c0efbcb45cf94724d17b040ebc03fcd4a81f22 ]
In cases where imx_clk_is_resource_owned() returns false, the code path
does not handle the failure gracefully, potentially leading to a memory
leak. This fix ensures proper cleanup by freeing the allocated memory
for 'clk_node' before returning.

From: Stanley.Yang <Stanley.Yang@amd.com>
[ Upstream commit a32c6f7f5737cc7e31cd7ad5133f0d96fca12ea6 ]
The ecc_irq is disabled while GPU mode2 reset suspending process,
but not be enabled during GPU mode2 reset resume process.
Changed from V1:
only do sdma/gfx ras_late_init in aldebaran_mode2_restore_ip
delete amdgpu_ras_late_resume function
Changed from V2:
check umc ras supported before put ecc_irq

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meenakshikumar Somasundaram <meenakshikumar.somasundaram@amd.com>
[ Upstream commit aa5dc05340eb97486a631ce6bccb8d020bf6b56b ]
[Why]
Fix minor issues in BW Allocation Phase2.
[How]
- In set_usb4_req_bw_req(), link->dpia_bw_alloc_config.response_ready
flag should be reset before writing DPCD REQUEST_BW.
- Fix the granularity for value of 2 in get_bw_granularity().
- Removed bandwidth allocation support display fw boot option as
the fw would read feature enable status from bios.
- Clean up DPIA_EST_BW_CHANGED and DPIA_BW_REQ_SUCCESS cases in
dpia_handle_bw_alloc_response().
- Removed allocate_usb4_bw and deallocate_usb4_bw.
- Optimized loop in get_lowest_dpia_index().
- Updated link_dp_dpia_allocate_usb4_bandwidth_for_stream() and
set_usb4_req_bw_req() to always issue request bw.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Kuehling <Felix.Kuehling@amd.com>
[ Upstream commit ec9ba4821fa52b5efdbc4cdf0a77497990655231 ]
Change the rules for amdgpu_sync_resv to let KFD synchronize with VM
fences on page table reservations. This fixes intermittent memory
corruption after evictions when using amdgpu_vm_handle_moved to update
page tables for VM mappings managed through render nodes.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Lipski <ivlipski@amd.com>
[ Upstream commit d6398866a6b47e92319ef6efdb0126a4fbb7796a ]
This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5.
Since, it causes a regression in which eDP displays with PSR support,
but no Replay support (Sink support <= 0x03), fail to enable PSR and
consequently all IGT amd_psr tests fail. So, revert this until a more
suitable fix can be found.
This got brought back accidently with the backmerge.

From: Alex Deucher <alexander.deucher@amd.com>
[ Upstream commit 16783d8ef08448815e149e40c82fc1e1fc41ddbf ]
These chips needs the same fix. This was previously not seen
on then since the AGP aperture expanded the system aperture,
but this showed up again when AGP was disabled.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: bo liu <bo.liu@senarytech.com>
[ Upstream commit 7aeb259086487417f0fecf66e325bee133e8813a ]
When OMTP headset plugin the headset jack of CX8070 and SN6160 sound cards,
the headset type detection circuit will recognize the headset type as CTIA.
At this point, plugout and plugin the headset will get the correct headset
type as OMTP.
The reason for the failure of headset type recognition is that the sound
card creation will enable the VREF voltage of the headset mic, which
interferes with the headset type automatic detection circuit. Plugout and
plugin the headset will restart the headset detection and get the correct
headset type.
The patch is disable the VREF voltage when the headset is not present, and
will enable the VREF voltage when the headset is present.

[ Upstream commit 236f9fe39b02c15fa5530b53e9cca48354394389 ]
The threads allocated inside the kernel have only a single page of
stack. Unfortunately, the vfprintf function in standard glibc may use
too much stack-space, overflowing it.
To make os_info safe to be used by helper threads, use the kernel
vscnprintf function into a smallish buffer and write out the information
to stderr.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit 7d748f60a4b82b50bf25fad1bd42d33f049f76aa ]
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
warning in clang aims to catch these at compile time, which reveals:
arch/um/drivers/net_kern.c:353:21: warning: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Wincompatible-function-pointer-types-strict]
353 | .ndo_start_xmit = uml_net_start_xmit,
| ^~~~~~~~~~~~~~~~~~
1 warning generated.
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of uml_net_start_xmit()
to match the prototype's to resolve the warning. While UML does not
currently implement support for kCFI, it could in the future, which
means this warning becomes a fatal CFI failure at run time.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit abe4eaa8618bb36c2b33e9cdde0499296a23448c ]
In 'basic' time-travel mode (without =inf-cpu or =ext), we
still get timer interrupts. These can happen at arbitrary
points in time, i.e. while in timer_read(), which pushes
time forward just a little bit. Then, if we happen to get
the interrupt after calculating the new time to push to,
but before actually finishing that, the interrupt will set
the time to a value that's incompatible with the forward,
and we'll crash because time goes backwards when we do the
forwarding.
Fix this by reading the time_travel_time, calculating the
adjustment, and doing the adjustment all with interrupts

From: Harshit Shah <harshitshah.opendev@gmail.com>
[ Upstream commit 374c13f9080a1b9835a5ed3e7bea93cf8e2dc262 ]
As per the Cadence IP document fixed the I2C clock divider value limit from
16 bits instead of 10 bits. Without this change setting up the I2C clock to
low frequencies will not work as the prescaler value might be greater than
10 bit number.
I3C clock divider value is 10 bits only. Updating the macro names for both.

------------------
From: Ben Mayo <benny1091@gmail.com>
[ Upstream commit d2aaf19965045f70bb2ece514399cdc6fcce2e73 ]
Asus Vivobook E1504GA and E1504GAB notebooks are affected by bug #216158
(DSDT specifies the kbd IRQ as level active-low and using the override
changes this to rising edge, stopping the keyboard from working).
Users of these notebooks do not have a working keyboard unless they add
their DMI information to the struct irq1_level_low_skip_override array
and compile a custom kernel.
Add support for these computers to the Linux kernel without requiring
the end-user to recompile the kernel.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Maltsev <mekosko@projectyo.network>
[ Upstream commit e315e8692f7922cd1b2a26bd7a1741cc8ce77085 ]
Like the ASUS ExpertBook B1502CBA and various ASUS laptops, the
ASUS ExpertBook B1502CGA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.
$ sudo dmesg | grep DMI
[ 0.000000] DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CGA_B1502CGA/B1502CGA, BIOS B1502CGA.303 06/05/2023
$ grep -A 40 PS2K dsdt.dsl | grep IRQ -A 1
IRQ (Level, ActiveLow, Exclusive, )
{1}
This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

XIP_FIXUP and a wrong page_offset value. A superfluous XIP_FIXUP
has also been removed.

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>
[ Upstream commit 2d2db7d40254d5fb53b11ebd703cd1ed0c5de7a1 ]
DO NOT access the underlying struct page of an sg table exported
by DMA-buf in dmabuf_imp_to_refs(), this is not allowed.
Please see drivers/dma-buf/dma-buf.c:mangle_sg_table() for details.
Fortunately, here (for special Xen device) we can avoid using
pages and calculate gfns directly from dma addresses provided by
the sg table.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xiaowu.ding <xiaowu.ding@jaguarmicro.com>
[ Upstream commit ee01c0b4384d19ecc5dfa7db3fd4303f965c3eba ]
Message Handling Unit version is v2.1.
When arm_mhuv2 working with the data protocol transfer mode.
We have split one mhu into two channels, and every channel
include four channel windows, the two channels share
one gic spi interrupt.
There is a problem with the sending scenario.
The first channel will take up 0-3 channel windows, and the second
channel take up 4-7 channel windows. When the first channel send the
data, and the receiver will clear all the four channels status.
Although we only enabled the interrupt on the last channel window with
register CH_INT_EN,the register CHCOMB_INT_ST0 will be 0xf, not be 0x8.
Currently we just clear the last channel windows int status with the
data proctol mode.So after that,the CHCOMB_INT_ST0 status will be 0x7,
not be the 0x0.
Then the second channel send the data, the receiver read the
data, clear all the four channel windows status, trigger the sender
interrupt. But currently the CHCOMB_INT_ST0 register will be 0xf7,
get_irq_chan_comb function will always return the first channel.
So this patch clear all channel windows int status to avoid this interrupt
confusion.

From: Guilherme G. Piccoli <gpiccoli@igalia.com>
[ Upstream commit e585a37e5061f6d5060517aed1ca4ccb2e56a34c ]
By running a Van Gogh device (Steam Deck), the following message
was noticed in the kernel log:
pci 0000:04:00.3: PCI class overridden (0x0c03fe -> 0x0c03fe) so dwc3 driver can claim this instead of xhci
Effectively this means the quirk executed but changed nothing, since the
class of this device was already the proper one (likely adjusted by newer
firmware versions).
Check and perform the override only if necessary.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Stodden <dns@arista.com>
[ Upstream commit df25461119d987b8c81d232cfe4411e91dcabe66 ]
A PCI device hot removal may occur while stdev->cdev is held open. The call
to stdev_release() then happens during close or exit, at a point way past
switchtec_pci_remove(). Otherwise the last ref would vanish with the
trailing put_device(), just before return.
At that later point in time, the devm cleanup has already removed the
stdev->mmio_mrpc mapping. Also, the stdev->pdev reference was not a counted
one. Therefore, in DMA mode, the iowrite32() in stdev_release() will cause
a fatal page fault, and the subsequent dma_free_coherent(), if reached,
would pass a stale &stdev->pdev->dev pointer.
Fix by moving MRPC DMA shutdown into switchtec_pci_remove(), after
stdev_kill(). Counting the stdev->pdev ref is now optional, but may prevent
future accidents.
Reproducible via the script at

------------------
From: James Clark <james.clark@arm.com>
[ Upstream commit 2dbba30fd69b604802a9535b74bddb5bcca23793 ]
Since commit d927ef5004ef ("perf cs-etm: Add exception level consistency
check"), the exception that was added to Perf will be triggered unless
the following bugfix from OpenCSD is present:
- _Version 1.2.1_:
- __Bugfix__:
ETM4x / ETE - output of context elements to client can in some
circumstances be delayed until after subsequent atoms have been
processed leading to incorrect memory decode access via the client
callbacks. Fixed to flush context elements immediately they are
committed.
Rather than remove the assert and silently fail, just increase the
minimum version requirement to avoid hard to debug issues and
regressions.

From: Mathias Nyman <mathias.nyman@linux.intel.com>
[ Upstream commit e2e2aacf042f52854c92775b7800ba668e0bdfe4 ]
There is a short gap between urb being submitted and actually added to the
endpoint queue (linked). If the device is disconnected during this time
then usb core is not yet aware of the pending urb, and device may be freed
just before xhci_urq_enqueue() continues, dereferencing the freed device.
Freeing the device is protected by the xhci spinlock, so make sure we take
and keep the lock while checking that device exists, dereference it, and
add the urb to the queue.
Remove the unnecessary URB check, usb core checks it before calling
xhci_urb_enqueue()

------------------
From: Hardik Gajjar <hgajjar@de.adit-jv.com>
[ Upstream commit 855d75cf8311fee156fabb5639bb53757ca83dd4 ]
There is a potential delay in notifying Linux USB drivers of downstream
USB bus activity when connecting a high-speed or superSpeed device via the
Microchip USB491x hub. This delay is due to the fixed bInterval value of
12 in the silicon of the Microchip USB491x hub.
Microchip requested to ignore the device descriptor and decrease that
value to 9 as it was too late to modify that in silicon.
This patch speeds up the USB enummeration process that helps to pass
Apple Carplay certifications and improve the User experience when utilizing
the USB device via Microchip Multihost USB491x Hub.
A new hub quirk HUB_QUIRK_REDUCE_FRAME_INTR_BINTERVAL speeds up
the notification process for Microchip USB491x hub by limiting
the maximum bInterval value to 9.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Reber <areber@redhat.com>
[ Upstream commit e0f25b8992345aa5f113da2815f5add98738c611 ]
The capability CAP_CHECKPOINT_RESTORE was introduced to allow non-root
users to checkpoint and restore processes as non-root with CRIU.
This change extends CAP_CHECKPOINT_RESTORE to enable the CRIU option
'--shell-job' as non-root. CRIU's man-page describes the '--shell-job'
option like this:
Allow one to dump shell jobs. This implies the restored task will
inherit session and process group ID from the criu itself. This option
also allows to migrate a single external tty connection, to migrate
applications like top.
TIOCSLCKTRMIOS can only be done if the process has CAP_SYS_ADMIN and
this change extends it to CAP_SYS_ADMIN or CAP_CHECKPOINT_RESTORE.
With this change it is possible to checkpoint and restore processes
which have a tty connection as non-root if CAP_CHECKPOINT_RESTORE is
set.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Max Kellermann <max.kellermann@ionos.com>
[ Upstream commit 5133bee62f0ea5d4c316d503cc0040cac5637601 ]
Handling of S_ISGID is usually done by inode_init_owner() in all other
filesystems, but kernfs doesn't use that function. In kernfs, struct
kernfs_node is the primary data structure, and struct inode is only
created from it on demand. Therefore, inode_init_owner() can't be
used and we need to imitate its behavior.
S_ISGID support is useful for the cgroup filesystem; it allows
subtrees managed by an unprivileged process to retain a certain owner
gid, which then enables sharing access to the subtree with another
unprivileged process.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yu-Che Cheng <giver@chromium.org>
[ Upstream commit e821d50ab5b956ed0effa49faaf29912fd4106d9 ]
The pmif driver data that contains the clocks is allocated along with
spmi_controller.
On device remove, spmi_controller will be freed first, and then devres
, including the clocks, will be cleanup.
This leads to UAF because putting the clocks will access the clocks in
the pmif driver data, which is already freed along with spmi_controller.
This can be reproduced by enabling DEBUG_TEST_DRIVER_REMOVE and
building the kernel with KASAN.
Fix the UAF issue by using unmanaged clk_bulk_get() and putting the
clocks before freeing spmi_controller.

Fix the issue of returning the -ENOSYS error code when an error occurs.
The error code of -ENOSYS indicates Invalid system call number, but
there is not system call error. So replace -ENOSYS error code by the
return -EINVAL error code.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Helgaas <bhelgaas@google.com>
[ Upstream commit 1291b716bbf969e101d517bfb8ba18d958f758b8 ]
When a device with AER detects an error, it logs error information in its
own AER Error Status registers. It may send an Error Message to the Root
Port (RCEC in the case of an RCiEP), which logs the fact that an Error
Message was received (Root Error Status) and the Requester ID of the
message source (Error Source Identification).
aer_print_port_info() prints the Requester ID from the Root Port Error
Source in the usual Linux "bb:dd.f" format, but when find_source_device()
finds no error details in the hierarchy below the Root Port, it printed the
raw Requester ID without decoding it.
Decode the Requester ID in the usual Linux format so it matches other
messages.
Sample message changes:
- pcieport 0000:00:1c.5: AER: Correctable error received: 0000:00:1c.5
- pcieport 0000:00:1c.5: AER: can't find device of ID00e5
+ pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5
+ pcieport 0000:00:1c.5: AER: found no error details for 0000:00:1c.5

From: David Howells <dhowells@redhat.com>
[ Upstream commit 9546ac78b232bac56ff975072b1965e0e755ebd4 ]
The 9p filesystem is calling netfs_inode_init() in v9fs_init_inode() -
before the struct inode fields have been initialised from the obtained file
stats (ie. after v9fs_stat2inode*() has been called), but netfslib wants to
set a couple of its fields from i_size.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt (Google) <rostedt@goodmis.org>
[ Upstream commit 8186fff7ab649085e2c60d032d9a20a85af1d87c ]
Instead of walking the dentries on mount/remount to update the gid values of
all the dentries if a gid option is specified on mount, just update the root
inode. Add .getattr, .setattr, and .permissions on the tracefs inode
operations to update the permissions of the files and directories.
For all files and directories in the top level instance:
/sys/kernel/tracing/*
It will use the root inode as the default permissions. The inode that
represents: /sys/kernel/tracing (or wherever it is mounted).
When an instance is created:
mkdir /sys/kernel/tracing/instance/foo
The directory "foo" and all its files and directories underneath will use
the default of what foo is when it was created. A remount of tracefs will
not affect it.
If a user were to modify the permissions of any file or directory in
tracefs, it will also no longer be modified by a change in ownership of a
remount.
The events directory, if it is in the top level instance, will use the
tracefs root inode as the default ownership for itself and all the files and
directories below it.
For the events directory in an instance ("foo"), it will keep the ownership
of what it was when it was created, and that will be used as the default
ownership for the files and directories beneath it.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yinbo Zhu <zhuyinbo@loongson.cn>
[ Upstream commit 6d6887c42e946f43bed2e64571a40c8476a1e4a9 ]
The xhci retaining bogus hardware states cause usb disconnect devices
connected before hibernation(s4) and refer to the commit 'f3d478858be
("usb: ohci-platform: fix usb disconnect issue after s4")' which set
flag "hibernated" as true when resume-from-hibernation and that the
drivers will reset the hardware to get rid of any existing state and
make sure resume from hibernation re-enumerates everything for xhci.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit b1b9f7a494400c0c39f8cd83de3aaa6111c55087 ]
The lis3lv02d_i2c driver was missing a line to set the lis3_dev's
reg_ctrl callback.
lis3_reg_ctrl(on) is called from the init callback, but due to
the missing reg_ctrl callback the regulators where never turned off
again leading to the following oops/backtrace when detaching the driver:

properly get turned off again when not used.

From: Ian Rogers <irogers@google.com>
[ Upstream commit ad30469a841b50dbb541df4d6971d891f703c297 ]
uniq() will write one command name over another causing the overwritten
string to be leaked. Fix by doing a pass that removes duplicates and a
second that removes the holes.

From: ChiYuan Huang <cy_huang@richtek.com>
[ Upstream commit 415d10ccef712f3ec73cd880c1fef3eb48601c3a ]
To enable TDM mode, the current control flow limits the function
calling order should be 'set_tdm_slot->set_dai_fmt'. But not all
platform sound card like as simeple card to follow this design.
To bypass this limit, adjust the DAI format setting in runtime
'hw_param' callback.

Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&svms->lock);
lock(&mm->mmap_lock);
lock(&svms->lock);
lock((work_completion)(&svm_bo->eviction_work));
I believe this cannot really lead to a deadlock in practice, because
svm_range_evict_svm_bo_worker only takes the mmap_read_lock if the BO
refcount is non-0. That means it's impossible that svm_range_bo_release
is running concurrently. However, there is no good way to annotate this.
To avoid the problem, take a BO reference in
svm_range_schedule_evict_svm_bo instead of in the worker. That way it's
impossible for a BO to get freed while eviction work is pending and the
cancel_work_sync call in svm_range_bo_release can be eliminated.
v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also
removed redundant checks that are already done in
amdkfd_fence_enable_signaling.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Lei <ming.lei@redhat.com>
[ Upstream commit 5266caaf5660529e3da53004b8b7174cab6374ed ]
In blk_mq_mark_tag_wait(), __add_wait_queue() may be re-ordered
with the following blk_mq_get_driver_tag() in case of getting driver
tag failure.
Then in __sbitmap_queue_wake_up(), waitqueue_active() may not observe
the added waiter in blk_mq_mark_tag_wait() and wake up nothing, meantime
blk_mq_mark_tag_wait() can't get driver tag successfully.
This issue can be reproduced by running the following test in loop, and
fio hang can be observed in < 30min when running it on my test VM
in laptop.
modprobe -r scsi_debug
modprobe scsi_debug delay=0 dev_size_mb=4096 max_queue=1 host_max_queue=1 submit_queues=4
dev=`ls -d /sys/bus/pseudo/drivers/scsi_debug/adapter*/host*/target*/*/block/* | head -1 | xargs basename`
fio --filename=/dev/"$dev" --direct=1 --rw=randrw --bs=4k --iodepth=1 \
--runtime=100 --numjobs=40 --time_based --name=test \
--ioengine=libaio
Fix the issue by adding one explicit barrier in blk_mq_mark_tag_wait(), which
is just fine in case of running out of tag.

From: Venky Shankar <vshankar@redhat.com>
[ Upstream commit f48e0342a74d7770cdf1d11894bdc3b6d989b29e ]
Following along the same lines as per the user-space fix. Right
now this isn't really an issue with the ceph kernel driver because
of the feature bit laginess, however, that can change over time
(when the new snaprealm info type is ported to the kernel driver)
and depending on the MDS version that's being upgraded can cause
message decoding issues - so, fix that early on.

From: Xiubo Li <xiubli@redhat.com>
[ Upstream commit b493ad718b1f0357394d2cdecbf00a44a36fa085 ]
The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.
But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wenchao Hao <haowenchao2@huawei.com>
[ Upstream commit 0f4cf64eabc6e16cfc2704f1960e82dc79d91c8d ]
This issue is reported by smatch that get_quota_realm() might return
ERR_PTR but we did not handle it. It's not a immediate bug, while we
still should address it to avoid potential bugs if get_quota_realm()
is changed to return other ERR_PTR in future.
Set ceph_snap_realm's pointer in get_quota_realm()'s to address this
issue, the pointer would be set to NULL if get_quota_realm() failed
to get struct ceph_snap_realm, so no ERR_PTR would happen any more.

In 'struct phm_ppm_table *ptr' allocation using kzalloc, an incorrect
structure type is passed to sizeof() in kzalloc, larger structure types
were used, thus using correct type 'struct phm_ppm_table' fixes the
below:

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>
[ Upstream commit fac4ebd79fed60e79cccafdad45a2bb8d3795044 ]
The amdgpu_gmc_vram_checking() function in emulation checks whether
all of the memory range of shared system memory could be accessed by
GPU, from this aspect, -EIO is returned for error scenarios.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/gmc_v6_0.c:919 gmc_v6_0_hw_init() warn: missing error code? 'r'
drivers/gpu/drm/amd/amdgpu/gmc_v7_0.c:1103 gmc_v7_0_hw_init() warn: missing error code? 'r'

From: Peter Zijlstra <peterz@infradead.org>
[ Upstream commit 388a1fb7da6aaa1970c7e2a7d7fcd983a87a8484 ]
Thomas reported that commit 652ffc2104ec ("perf/core: Fix narrow
startup race when creating the perf nr_addr_filters sysfs file") made
the entire attribute group vanish, instead of only the nr_addr_filters
attribute.
Additionally a stray return.
Insufficient coffee was involved with both writing and merging the
patch.

commit 66f1e6809397 ("riscv: Make XIP bootable again") restricted page
offset to the sv39 page offset instead of the default sv57, which makes
sense since probably the platforms that target XIP kernels do not
support anything else than sv39 and we do not try to find out the
largest address space supported on XIP kernels (ie set_satp_mode()).
But PAGE_OFFSET_L3 is not defined for rv32, so fix the build error by
restoring the previous behaviour which picks CONFIG_PAGE_OFFSET for rv32.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marco Pagani <marpagan@redhat.com>
[ Upstream commit a1af6a2bfa0cb46d70b7df5352993e750da6c79b ]
Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in
kunit_free_suite_set()") fixed a wild-memory-access bug that could have
happened during the loading phase of test suites built and executed as
loadable modules. However, it also introduced a problematic side effect
that causes test suites modules to crash when they attempt to register
fake devices.
When a module is loaded, it traverses the MODULE_STATE_UNFORMED and
MODULE_STATE_COMING states before reaching the normal operating state
MODULE_STATE_LIVE. Finally, when the module is removed, it moves to
MODULE_STATE_GOING before being released. However, if the loading
function load_module() fails between complete_formation() and
do_init_module(), the module goes directly from MODULE_STATE_COMING to
MODULE_STATE_GOING without passing through MODULE_STATE_LIVE.
This behavior was causing kunit_module_exit() to be called without
having first executed kunit_module_init(). Since kunit_module_exit() is
responsible for freeing the memory allocated by kunit_module_init()
through kunit_filter_suites(), this behavior was resulting in a
wild-memory-access bug.
Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in
kunit_free_suite_set()") fixed this issue by running the tests when the
module is still in MODULE_STATE_COMING. However, modules in that state
are not fully initialized, lacking sysfs kobjects. Therefore, if a test
module attempts to register a fake device, it will inevitably crash.
This patch proposes a different approach to fix the original
wild-memory-access bug while restoring the normal module execution flow
by making kunit_module_exit() able to detect if kunit_module_init() has
previously initialized the tests suite set. In this way, test modules
can once again register fake devices without crashing.
This behavior is achieved by checking whether mod->kunit_suites is a
virtual or direct mapping address. If it is a virtual address, then
kunit_module_init() has allocated the suite_set in kunit_filter_suites()
using kmalloc_array(). On the contrary, if mod->kunit_suites is still
pointing to the original address that was set when looking up the
.kunit_test_suites section of the module, then the loading phase has
failed and there's no memory to be freed.
v4:
- rebased on 6.8
- noted that kunit_filter_suites() must return a virtual address
v3:
- add a comment to clarify why the start address is checked
v2:
- add include <linux/mm.h>

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Romain Naour <romain.naour@skf.com>
[ Upstream commit a67e1f0bd4564b485e0f0c3ed7f6bf17688be268 ]
We can't use devm_platform_ioremap_resource_byname() to remap the
interrupt register that can be shared between
regulator-abb-{ivahd,dspeve,gpu} drivers instances.
The combined helper introduce a call to devm_request_mem_region() that
creates a new busy resource region on PRM_IRQSTATUS_MPU register
(0x4ae06010). The first devm_request_mem_region() call succeeds for
regulator-abb-ivahd but fails for the two other regulator-abb-dspeve
and regulator-abb-gpu.
# cat /proc/iomem | grep -i 4ae06
4ae06010-4ae06013 : 4ae07e34.regulator-abb-ivahd int-address
4ae06014-4ae06017 : 4ae07ddc.regulator-abb-mpu int-address
regulator-abb-dspeve and regulator-abb-gpu are missing due to
devm_request_mem_region() failure (EBUSY):
[ 1.326660] ti_abb 4ae07e30.regulator-abb-dspeve: can't request region for resource [mem 0x4ae06010-0x4ae06013]
[ 1.326660] ti_abb: probe of 4ae07e30.regulator-abb-dspeve failed with error -16
[ 1.327239] ti_abb 4ae07de4.regulator-abb-gpu: can't request region for resource [mem 0x4ae06010-0x4ae06013]
[ 1.327270] ti_abb: probe of 4ae07de4.regulator-abb-gpu failed with error -16
>From arm/boot/dts/dra7.dtsi:
The abb_mpu is the only instance using its own interrupt register:
(0x4ae06014) PRM_IRQSTATUS_MPU_2, ABB_MPU_DONE_ST (bit 7)
The other tree instances (abb_ivahd, abb_dspeve, abb_gpu) share
PRM_IRQSTATUS_MPU register (0x4ae06010) but use different bits
ABB_IVA_DONE_ST (bit 30), ABB_DSPEVE_DONE_ST( bit 29) and
ABB_GPU_DONE_ST (but 28).
The commit b36c6b1887ff ("regulator: ti-abb: Make use of the helper
function devm_ioremap related") overlooked the following comment
implicitly explaining why devm_ioremap() is used in this case:
/*
* We may have shared interrupt register offsets which are
* write-1-to-clear between domains ensuring exclusivity.
*/
Fixes and partially reverts commit b36c6b1887ff ("regulator: ti-abb:
Make use of the helper function devm_ioremap related").
Improve the existing comment to avoid further conversion to
devm_platform_ioremap_resource_byname().

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Lei <ming.lei@redhat.com>
[ Upstream commit 4373534a9850627a2695317944898eb1283a2db0 ]
Inside scsi_eh_wakeup(), scsi_host_busy() is called & checked with host
lock every time for deciding if error handler kthread needs to be waken up.
This can be too heavy in case of recovery, such as:
- N hardware queues
- queue depth is M for each hardware queue
- each scsi_host_busy() iterates over (N * M) tag/requests
If recovery is triggered in case that all requests are in-flight, each
scsi_eh_wakeup() is strictly serialized, when scsi_eh_wakeup() is called
for the last in-flight request, scsi_host_busy() has been run for (N * M -
1) times, and request has been iterated for (N*M - 1) * (N * M) times.
If both N and M are big enough, hard lockup can be triggered on acquiring
host lock, and it is observed on mpi3mr(128 hw queues, queue depth 8169).
Fix the issue by calling scsi_host_busy() outside the host lock. We don't
need the host lock for getting busy count because host the lock never
covers that.

From: Paolo Abeni <pabeni@redhat.com>
[ Upstream commit 98cb12eb52a780e682bea8372fdb2912c08132dd ]
Several net tests requires an XDP program build under the ebpf
directory, and error out if such program is not available.
That makes running successful net test hard, let's duplicate into the
net dir the [very small] program, re-using the existing rules to build
it, and finally dropping the bogus dependency.

From: Paolo Abeni <pabeni@redhat.com>
[ Upstream commit 4acffb66630a0e4800880baa61a54ef18047ccd3 ]
The UDP GRO forwarding test still hard-code an arbitrary pause
to wait for the UDP listener becoming ready in background.
That causes sporadic failures depending on the host load.
Replace the sleep with the existing helper waiting for the desired
port being exposed.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gaurav Jain <gaurav.jain@nxp.com>
[ Upstream commit c5a2f74db71a849f3a60bc153d684d6d28a0c665 ]
ahash_alg->setkey is updated to ahash_nosetkey in ahash.c
so checking setkey() function to determine hmac algorithm is not valid.
to fix this added is_hmac variable in structure caam_hash_alg to determine
whether the algorithm is hmac or not.
Fixes: 2f1f34c1bf7b ("crypto: ahash - optimize performance when wrapping shash")

------------------
From: Paolo Abeni <pabeni@redhat.com>
[ Upstream commit fcf67d82b8b878bdd95145382be43927bce07ec6 ]
The big_tcp test-case requires a few kernel knobs currently
not specified in the net selftests config, causing the
following failure:
# selftests: net: big_tcp.sh
# Error: Failed to load TC action module.
# We have an error talking to the kernel
...
# Testing for BIG TCP:
# CLI GSO | GW GRO | GW GSO | SER GRO
# ./big_tcp.sh: line 107: test: !=: unary operator expected
...
# on on on on : [FAIL_on_link1]
Add the missing configs

------------------
From: Paolo Abeni <pabeni@redhat.com>
[ Upstream commit 89abe628375301fedb68770644df845d49018d8b ]
The gro.sh test-case relay on the gro_flush_timeout to ensure
that all the segments belonging to any given batch are properly
aggregated.
The other end, the sender is a user-space program transmitting
each packet with a separate write syscall. A busy host and/or
stracing the sender program can make the relevant segments reach
the GRO engine after the flush timeout triggers.
Give the GRO flush timeout more slack, to avoid sporadic self-tests
failures.

The original packet in ipmr_cache_report() may be queued and then forwarded
with ip_mr_forward(). This last function has the assumption that the skb
dst is set.
After the below commit, the skb dst is dropped by ipv4_pktinfo_prepare(),
which causes the oops.

In case the interface between the MAC and the PHY is SGMII, then the bit
GIGA_MODE on the MAC side needs to be set regardless of the speed at
which it is running.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 577e4432f3ac810049cb7e6b71f4d96ec7c6e894 ]
TCP rx zerocopy intent is to map pages initially allocated
from NIC drivers, not pages owned by a fs.
This patch adds to can_map_frag() these additional checks:
- Page must not be a compound one.
- page->mapping must be NULL.
This fixes the panic reported by ZhangPeng.
syzbot was able to loopback packets built with sendfile(),
mapping pages owned by an ext4 file to TCP rx zerocopy.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jacob Keller <jacob.e.keller@intel.com>
[ Upstream commit f1f6a6b1830a8f1dc92ee26fae76333f446b0663 ]
The e1000e driver supports hardware with a variety of different clock
speeds, and thus a variety of different increment values used for
programming its PTP hardware clock.
The values currently programmed in e1000e_ptp_init are incorrect. In
particular, only two maximum adjustments are used: 24000000 - 1, and
600000000 - 1. These were originally intended to be used with the 96 MHz
clock and the 25 MHz clock.
Both of these values are actually slightly too high. For the 96 MHz clock,
the actual maximum value that can safely be programmed is 23,999,938. For
the 25 MHz clock, the maximum value is 599,999,904.
Worse, several devices use a 24 MHz clock or a 38.4 MHz clock. These parts
are incorrectly assigned one of either the 24million or 600million values.
For the 24 MHz clock, this is not a significant issue: its current
increment value can support an adjustment up to 7billion in the positive
direction. However, the 38.4 KHz clock uses an increment value which can
only support up to 230,769,157 before it starts overflowing.
To understand where these values come from, consider that frequency
adjustments have the form of:
new_incval = base_incval + (base_incval * adjustment) / (unit of adjustment)
The maximum adjustment is reported in terms of parts per billion:
new_incval = base_incval + (base_incval * adjustment) / 1 billion
The largest possible adjustment is thus given by the following:
max_incval = base_incval + (base_incval * max_adj) / 1 billion
Re-arranging to solve for max_adj:
max_adj = (max_incval - base_incval) * 1 billion / base_incval
We also need to ensure that negative adjustments cannot underflow. This can
be achieved simply by ensuring max_adj is always less than 1 billion.
Introduce new macros in e1000.h codifying the maximum adjustment in PPB for
each frequency given its associated increment values. Also clarify where
these values come from by commenting about the above equations.
Replace the switch statement in e1000e_ptp_init with one which mirrors the
increment value switch statement from e1000e_get_base_timinica. For each
device, assign the appropriate maximum adjustment based on its frequency.
Some parts can have one of two frequency modes as determined by
E1000_TSYNCRXCTL_SYSCFI.
Since the new flow directly matches the assignments in
e1000e_get_base_timinca, and uses well defined macro names, it is much
easier to verify that the resulting maximum adjustments are correct. It
also avoids difficult to parse construction such as the "hw->mac.type <
e1000_phc_lpt", and the use of fallthrough which was especially confusing
when combined with a conditional block.
Note that I believe the current increment value configuration used for
24MHz clocks is sub-par, as it leaves at least 3 extra bits available in
the INCVALUE register. However, fixing that requires more careful review of
the clock rate and associated values.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jedrzej Jagielski <jedrzej.jagielski@intel.com>
[ Upstream commit 6c1b4af8c1b20c70dde01e58381685d6a4a1d2c8 ]
Currently ixgbe driver is notified of overheating events
via internal IXGBE_ERR_OVERTEMP error code.
Change the approach for handle_lasi() to use freshly introduced
is_overtemp function parameter which set when such event occurs.
Change check_overtemp() to bool and return true if overtemp
event occurs.

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit bbc404d20d1b46d89b461918bc44587620eda200 ]
All error handling paths, except this one, go to 'out' where
release_swfw_sync() is called.
This call balances the acquire_swfw_sync() call done at the beginning of
the function.
Branch to the error handling path in order to correctly release some
resources in case of error.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Vokáč <michal.vokac@ysoft.com>
[ Upstream commit c44fc98f0a8ffd94fa0bd291928e7e312ffc7ca4 ]
When working with GPIO, its direction must be set either when the GPIO is
requested by gpiod_get*() or later on by one of the gpiod_direction_*()
functions. Neither of this is done here which results in undefined
behavior on some systems.
As the reset GPIO is used right after it is requested here, it makes sense
to configure it as GPIOD_OUT_HIGH right away. With that, the following
gpiod_set_value_cansleep(1) becomes redundant and can be safely
removed.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@kernel.org>
[ Upstream commit 60365049ccbacd101654a66ddcb299abfabd4fc5 ]
On a parisc64 kernel I sometimes notice this kernel warning:
Kernel unaligned access to 0x40ff8814 at ndisc_send_skb+0xc0/0x4d8
The address 0x40ff8814 points to the in6addr_linklocal_allrouters
variable and the warning simply means that some ipv6 function tries to
read a 64-bit word directly from the not-64-bit aligned
in6addr_linklocal_allrouters variable.
Unaligned accesses are non-critical as the architecture or exception
handlers usually will fix it up at runtime. Nevertheless it may trigger
a performance penality for some architectures. For details read the
"unaligned-memory-access" kernel documentation.
The patch below ensures that the ipv6 loopback and router addresses will
always be naturally aligned. This prevents the unaligned accesses for
all architectures.

------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit aa2b2eb3934859904c287bf5434647ba72e14c1c ]
syzbot reported an interesting trace [1] caused by a stale sk->sk_wq
pointer in a closed llc socket.
In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after
calling proto_ops::release()") Eric Biggers hinted that some protocols
are missing a sock_orphan(), we need to perform a full audit.
In net-next, I plan to clear sock->sk from sock_orphan() and
amend Eric patch to add a warning.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit b40f873a7c80dbafbb6f4a7a569f2dcaf969d283 ]
One of the test cases in the test_bridge_backup_port.sh selftest relies
on a matchall classifier to drop unrelated traffic so that the Tx drop
counter on the VXLAN device will only be incremented as a result of
traffic generated by the test.
However, the configuration option for the matchall classifier is
missing from the configuration file which might explain the failures we
see in the netdev CI [1].
Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

# Backup nexthop ID - invalid IDs
# -------------------------------

# TEST: Forwarding out of vx0 [ OK ]
# TEST: No forwarding using backup nexthop ID [ OK ]

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Lüssing <linus.luessing@c0d3.blue>
[ Upstream commit f5c3eb4b7251baba5cd72c9e93920e710ac8194a ]
The original idea of the delay_time check was to not apply multicast
snooping too early when an MLD querier appears. And to instead wait at
least for MLD reports to arrive before switching from flooding to group
based, MLD snooped forwarding, to avoid temporary packet loss.
However in a batman-adv mesh network it was noticed that after 248 days of
uptime 32bit MIPS based devices would start to signal that they had
stopped applying multicast snooping due to missing queriers - even though
they were the elected querier and still sending MLD queries themselves.
While time_is_before_jiffies() generally is safe against jiffies
wrap-arounds, like the code comments in jiffies.h explain, it won't
be able to track a difference larger than ULONG_MAX/2. With a 32bit
large jiffies and one jiffies tick every 10ms (CONFIG_HZ=100) on these MIPS
devices running OpenWrt this would result in a difference larger than
ULONG_MAX/2 after 248 (= 2^32/100/60/60/24/2) days and
time_is_before_jiffies() would then start to return false instead of
true. Leading to multicast snooping not being applied to multicast
packets anymore.
Fix this issue by using a proper timer_list object which won't have this
ULONG_MAX/2 difference limitation.
Fixes: b00589af3b04 ("bridge: disable snooping if there is no querier")

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Parav Pandit <parav@nvidia.com>
[ Upstream commit 1a89e24f8bfd3e3562d69709c9d9cd185ded869b ]
When port function state change is requested, and when the driver
does not support it, it refers to the hw address attribute instead
of state attribute. Seems like a copy paste error.
Fix it by referring to the port function state attribute.
Fixes: c0bea69d1ca7 ("devlink: Validate port function request")

[ Upstream commit c9ec85153fea6873c52ed4f5055c87263f1b54f9 ]
l2_tos_ttl_inherit.sh verifies the inheritance of tos and ttl
for GRETAP, VXLAN and GENEVE.
Before testing it checks if the required module is available
and if not skips the tests accordingly.
Currently only GRETAP and VXLAN are tested because the GENEVE
module is missing.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryan Schaefer <ryanschf@amazon.com>
[ Upstream commit fb366fc7541a1de521ab3df58471746aa793b833 ]
commit c7aab4f17021 ("netfilter: nf_conntrack_tcp: re-init for syn packets
only") introduces a bug where SYNs in ORIGINAL direction on reused 5-tuple
result in incorrect window scale negotiation. This commit merged the SYN
re-initialization and simultaneous open or SYN retransmits cases. Merging
this block added the logic in tcp_init_sender() that performed window scale
negotiation to the retransmitted syn case. Previously. this would only
result in updating the sender's scale and flags. After the merge the
additional logic results in improperly clearing the scale in ORIGINAL
direction before any packets in the REPLY direction are received. This
results in packets incorrectly being marked invalid for being
out-of-window.
This can be reproduced with the following trace:
Packet Sequence:
> Flags [S], seq 1687765604, win 62727, options [.. wscale 7], length 0
> Flags [S], seq 1944817196, win 62727, options [.. wscale 7], length 0
In order to fix the issue, only evaluate window negotiation for packets
in the REPLY direction. This was tested with simultaneous open, fast
open, and the above reproduction.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jozsef Kadlecsik <kadlec@netfilter.org>
[ Upstream commit 97f7cf1cd80eeed3b7c808b7c12463295c751001 ]
The patch "netfilter: ipset: fix race condition between swap/destroy
and kernel side add/del/test", commit 28628fa9 fixes a race condition.
But the synchronize_rcu() added to the swap function unnecessarily slows
it down: it can safely be moved to destroy and use call_rcu() instead.
Eric Dumazet pointed out that simply calling the destroy functions as
rcu callback does not work: sets with timeout use garbage collectors
which need cancelling at destroy which can wait. Therefore the destroy
functions are split into two: cancelling garbage collectors safely at
executing the command received by netlink and moving the remaining
part only into the rcu callback.

[ Upstream commit 259eb32971e9eb24d1777a28d82730659f50fdcb ]
Module reference is bumped for each user, this should not ever happen.
But BUG_ON check should use rcu_access_pointer() instead.
If this ever happens, do WARN_ON_ONCE() instead of BUG_ON() and
consolidate pointer check under the rcu read side lock section.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
[ Upstream commit 4d322dce82a1d44f8c83f0f54f95dd1b8dcf46c9 ]
syzbot reported a lockdep splat [1].
Blamed commit hinted about the possible lockdep
violation, and code used unix_state_lock_nested()
in an attempt to silence lockdep.
It is not sufficient, because unix_state_lock_nested()
is already used from unix_state_double_lock().
We need to use a separate subclass.
This patch adds a distinct enumeration to make things
more explicit.
Also use swap() in unix_state_double_lock() as a clean up.
v2: add a missing inline keyword to unix_state_lock_nested()

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit d9407ff11809c6812bb84fe7be9c1367d758e5c8 ]
The PCIe reset handlers can run at the same time as the
health thread. This can cause the health thread to
stomp on the PCIe reset. Fix this by preventing the
health thread from running while a PCIe reset is happening.
As part of this use timer_shutdown_sync() during reset and
remove to make sure the timer doesn't ever get rearmed.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit d321067e2cfa4d5e45401a00912ca9da8d1af631 ]
There is a small window where pdsc_work_thread()
calls pdsc_process_adminq() and pdsc_process_adminq()
passes the PDSC_S_STOPPING_DRIVER check and starts
to process adminq/notifyq work and then the driver
starts a fw_down cycle. This could cause some
undefined behavior if the notifyqcq/adminqcq are
free'd while pdsc_process_adminq() is running. Use
cancel_work_sync() on the adminqcq's work struct
to make sure any pending work items are cancelled
and any in progress work items are completed.
Also, make sure to not call cancel_work_sync() if
the work item has not be initialized. Without this,
traces will happen in cases where a reset fails and
teardown is called again or if reset fails and the
driver is removed.

From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit 951705151e50f9022bc96ec8b3fd5697380b1df6 ]
The initial design for the adminq interrupt was done based
on client drivers having their own adminq and adminq
interrupt. So, each client driver's adminq isr would use
their specific adminqcq for the private data struct. For the
time being the design has changed to only use a single
adminq for all clients. So, instead use the struct pdsc for
the private data to simplify things a bit.
This also has the benefit of not dereferencing the adminqcq
to access the pdsc struct when the PDSC_S_STOPPING_DRIVER bit
is set and the adminqcq has actually been cleared/freed.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit 7e82a8745b951b1e794cc780d46f3fbee5e93447 ]
There are multiple paths that can result in using the pdsc's
adminq.
[1] pdsc_adminq_isr and the resulting work from queue_work(),
i.e. pdsc_work_thread()->pdsc_process_adminq()
[2] pdsc_adminq_post()
When the device goes through reset via PCIe reset and/or
a fw_down/fw_up cycle due to bad PCIe state or bad device
state the adminq is destroyed and recreated.
A NULL pointer dereference can happen if [1] or [2] happens
after the adminq is already destroyed.
In order to fix this, add some further state checks and
implement reference counting for adminq uses. Reference
counting was used because multiple threads can attempt to
access the adminq at the same time via [1] or [2]. Additionally,
multiple clients (i.e. pds-vfio-pci) can be using [2]
at the same time.
The adminq_refcnt is initialized to 1 when the adminq has been
allocated and is ready to use. Users/clients of the adminq
(i.e. [1] and [2]) will increment the refcnt when they are using
the adminq. When the driver goes into a fw_down cycle it will
set the PDSC_S_FW_DEAD bit and then wait for the adminq_refcnt
to hit 1. Setting the PDSC_S_FW_DEAD before waiting will prevent
any further adminq_refcnt increments. Waiting for the
adminq_refcnt to hit 1 allows for any current users of the adminq
to finish before the driver frees the adminq. Once the
adminq_refcnt hits 1 the driver clears the refcnt to signify that
the adminq is deleted and cannot be used. On the fw_up cycle the
driver will once again initialize the adminq_refcnt to 1 allowing
the adminq to be used again.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit e96094c1d11cce4deb5da3c0500d49041ab845b8 ]
During reset the BARs might be accessed when they are
unmapped. This can cause unexpected issues, so fix it by
clearing the cached BAR values so they are not accessed
until they are re-mapped.
Also, make sure any places that can access the BARs
when they are NULL are prevented.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brett Creeley <brett.creeley@amd.com>
[ Upstream commit bc90fbe0c3182157d2be100a2f6c2edbb1820677 ]
Currently the teardown/setup flow for driver probe/remove is quite
a bit different from the reset flows in pdsc_fw_down()/pdsc_fw_up().
One key piece that's missing are the calls to pci_alloc_irq_vectors()
and pci_free_irq_vectors(). The pcie reset case is calling
pci_free_irq_vectors() on reset_prepare, but not calling the
corresponding pci_alloc_irq_vectors() on reset_done. This is causing
unexpected/unwanted interrupt behavior due to the adminq interrupt
being accidentally put into legacy interrupt mode. Also, the
pci_alloc_irq_vectors()/pci_free_irq_vectors() functions are being
called directly in probe/remove respectively.
Fix this inconsistency by making the following changes:
1. Always call pdsc_dev_init() in pdsc_setup(), which calls
pci_alloc_irq_vectors() and get rid of the now unused
pds_dev_reinit().
2. Always free/clear the pdsc->intr_info in pdsc_teardown()
since this structure will get re-alloced in pdsc_setup().
3. Move the calls of pci_free_irq_vectors() to pdsc_teardown()
since pci_alloc_irq_vectors() will always be called in
pdsc_setup()->pdsc_dev_init() for both the probe/remove and
reset flows.
4. Make sure to only create the debugfs "identity" entry when it
doesn't already exist, which it will in the reset case because
it's already been created in the initial call to pdsc_dev_init().

From: Jakub Kicinski <kuba@kernel.org>
[ Upstream commit 59c93583491ab15db109f9902524d241c4fa4c0b ]
Modern OSes use iptables implementation with nf_tables as a backend,
e.g.:
$ iptables -V
iptables v1.8.8 (nf_tables)
Pablo points out that we need CONFIG_NFT_COMPAT to make that work,
otherwise we see a lot of:
Warning: Extension DNAT revision 0 not supported, missing kernel module?
with DNAT being just an example here, other modules we need
include udp, TTL, length etc.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@redhat.com>
[ Upstream commit e4e4b6d568d2549583cbda3f8ce567e586cb05da ]
The pmtu.sh test tries to detect the tunnel protocols available
in the running kernel and properly skip the unsupported cases.
In a few more complex setup, such detection is unsuccessful, as
the script currently ignores some intermediate error code at
setup time.
Before:
# which: no nettest in (/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)
# TEST: vti6: PMTU exceptions (ESP-in-UDP) [FAIL]
# PMTU exception wasn't created after creating tunnel exceeding link layer MTU
# ./pmtu.sh: line 931: kill: (7543) - No such process
# ./pmtu.sh: line 931: kill: (7544) - No such process
After:
# xfrm4 not supported
# TEST: vti4: PMTU exceptions [SKIP]
Fixes: ece1278a9b81 ("selftests: net: add ESP-in-UDP PMTU test")

[ Upstream commit bc0970d5ac1d1317e212bdf55533935ecb6ae95c ]
When running the pmtu.sh via the kselftest infra, accessing
/dev/stdout gives unexpected results:

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geetha sowjanya <gakula@marvell.com>
[ Upstream commit 04f647c8e456fcfabe9c252a4dcaee03b586fa4f ]
XDP queues are created/destroyed when a XDP program
is attached/detached. In current driver xdp_queues are not
getting destroyed on program exit due to incorrect xdp_queue
and tot_tx_queue count values.
This patch fixes the issue by setting tot_tx_queue and xdp_queue
count to correct values. It also fixes xdp.data_hard_start address.

------------------
From: Benjamin Poirier <bpoirier@nvidia.com>
[ Upstream commit 7b6fb3050d8f5e2b6858eef344e47ac1f5442827 ]
Similar to commit dd2d40acdbb2 ("selftests: bonding: Add more missing
config options"), add more networking-specific config options which are
needed for team device tests.
For testing, I used the minimal config generated by virtme-ng and I added
the options in the config file. Afterwards, the team device test passed.

[ Upstream commit 8cc063ae1b3dbe416ce62a15d49af4c2314b45fe ]
The purpose of the test_LAG_cleanup() function is to check that some
hardware addresses are removed from underlying devices after they have been
unenslaved. The test function simply checks that those addresses are not
present at the end. However, if the addresses were never added to begin
with due to some error in device setup, the test function currently passes.
This is a false positive since in that situation the test did not actually
exercise the intended functionality.
Add a check that the expected addresses are indeed present after device
setup. This makes the test function more robust.
I noticed this problem when running the team/dev_addr_lists.sh test on a
system without support for dummy and ipv6:
tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh
Error: Unknown device type.
Error: Unknown device type.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pavan Kumar Linga <pavan.kumar.linga@intel.com>
[ Upstream commit f0588b157f48b9c6277a75c9f14650e86d969e03 ]
In the arm random config file, kconfig option 'CONFIG_AEABI' is
disabled which results in adding the compiler flag '-mabi=apcs-gnu'.
This causes the compiler to add padding in virtchnl2_ptype
structure to align it to 8 bytes, resulting in the following
size check failure:
include/linux/build_bug.h:78:41: error: static assertion failed: "(6) == sizeof(struct virtchnl2_ptype)"
78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg)

| ^~~~~~~~~~~~~~~~~~~~~~~~~~
Avoid the compiler padding by using "__packed" structure
attribute for the virtchnl2_ptype struct. Also align the
structure by using "__aligned(2)" for better code optimization.

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

From: Huang Shijie <shijie@os.amperecomputing.com>
commit 7b1a09e44dc64f4f5930659b6d14a27183c00705 upstream.
The init_irq_stacks() has been changed to use the correct node:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=75b5e0bf90bf
The init_irq_scs() has the same issue with init_irq_stacks():
cpu_to_node() is not initialized yet, it does not work.
This patch uses early_cpu_to_node() to set the init_irq_scs()
with the correct node.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marco Elver <elver@google.com>
commit f6564fce256a3944aa1bc76cb3c40e792d97c1eb upstream.
Alexander Potapenko writes in [1]: "For every memory access in the code
instrumented by KMSAN we call kmsan_get_metadata() to obtain the metadata
for the memory being accessed. For virtual memory the metadata pointers
are stored in the corresponding `struct page`, therefore we need to call
virt_to_page() to get them.
According to the comment in arch/x86/include/asm/page.h,
virt_to_page(kaddr) returns a valid pointer iff virt_addr_valid(kaddr) is
true, so KMSAN needs to call virt_addr_valid() as well.
To avoid recursion, kmsan_get_metadata() must not call instrumented code,
therefore ./arch/x86/include/asm/kmsan.h forks parts of
arch/x86/mm/physaddr.c to check whether a virtual address is valid or not.
But the introduction of rcu_read_lock() to pfn_valid() added instrumented
RCU API calls to virt_to_page_or_null(), which is called by
kmsan_get_metadata(), so there is an infinite recursion now. I do not
think it is correct to stop that recursion by doing
kmsan_enter_runtime()/kmsan_exit_runtime() in kmsan_get_metadata(): that
would prevent instrumented functions called from within the runtime from
tracking the shadow values, which might introduce false positives."
Fix the issue by switching pfn_valid() to the _sched() variant of
rcu_read_lock/unlock(), which does not require calling into RCU. Given
the critical section in pfn_valid() is very small, this is a reasonable
trade-off (with preemptible RCU).
KMSAN further needs to be careful to suppress calls into the scheduler,
which would be another source of recursion. This can be done by wrapping
the call to pfn_valid() into preempt_disable/enable_no_resched(). The
downside is that this sacrifices breaking scheduling guarantees; however,
a kernel compiled with KMSAN has already given up any performance
guarantees due to being heavily instrumented.
Note, KMSAN code already disables tracing via Makefile, and since mmzone.h
is included, it is not necessary to use the notrace variant, which is
generally preferred in all other cases.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konrad Dybcio <konrad.dybcio@linaro.org>
commit 6ab502bc1cf3147ea1d8540d04b83a7a4cb6d1f1 upstream.
Some devices power the DSI PHY/PLL through a power rail that we model
as a GENPD. Enable runtime PM to make it suspendable.

6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonghong Song <yonghong.song@linux.dev>
commit 56925f389e152dcb8d093435d43b78a310539c23 upstream.
With previous patch, one of subtests in test_btf_id becomes
flaky and may fail. The following is a failing example:
Error: #26 btf
Error: #26/174 btf/BTF ID
Error: #26/174 btf/BTF ID
btf_raw_create:PASS:check 0 nsec
btf_raw_create:PASS:check 0 nsec
test_btf_id:PASS:check 0 nsec
...
test_btf_id:PASS:check 0 nsec
test_btf_id:FAIL:check BTF lingersdo_test_get_info:FAIL:check failed: -1
The test tries to prove a btf_id not available after the map is closed.
But btf_id is freed only after workqueue and a rcu grace period, compared
to previous case just after a rcu grade period.
Depending on system workload, workqueue could take quite some time
to execute function bpf_map_free_deferred() which may cause the test failure.
Instead of adding arbitrary delays, let us remove the logic to
check btf_id availability after map is closed.

As suggested by Paolo in link[1], if the memory allocation fails, the mm
layer will emit a lot warning comprising the backtrace, so remove the
print.

Same problems as reported with 6.1, but something else happening on Arm (32-bits):
-----8<-----
Error: /builds/linux/arch/arm/boot/dts/qcom/qcom-msm8960-cdp.dts:91.1-10 Label or path pmicintc not found
FATAL ERROR: Syntax error parsing input tree

make[4]: Target 'arch/arm/boot/dts/qcom/' not remade because of errors.
----->8-----
This is seen with Clang (17 and nightly) and GCC-8.
Bisection here points to:
commit 4fed142bbe3ca920810eba12fe96800cfd094d0c

On my Zen2-based Thinkpad I now get the trace below on boot; this never
happened before. The boot continues and the system seems usable.
It's out-of-order because apparently there's a workqueue involved,
but most of the information points to the patch called
"xhci-fix-possible-null-pointer-deref-during-xhci-urb.patch".

Looks good to me
This patch depends on 53f3811dfd5e39507ee3aaea1be09aabce8f9c98 "sysctl:
Use ctl_table_size as stopping criteria for list macro" and
1e887723545e037b5e200e77edf79802f58fc818 "sysctl: Add ctl_table_size to
ctl_table_header" which are both in 6.7 and 6.6.
Best
