Subject: sh: Do not use hyphen in exported variable names
arch/sh/Makefile defines and exports ld-bfd to be used by
arch/sh/boot/Makefile and arch/sh/boot/compressed/Makefile. However
some shells, including dash, will not pass through environment
variables whose name includes a hyphen. Usually GNU make does not use
a shell to recurse, but if e.g. $(srctree) contains '~' it will use a
shell here.
Rename the variable to ld_bfd.
(Another instance of this problem was fixed upstream by commit
82977af93a0d "sh: rename suffix-y to suffix_y".)

Subject: android: Enable building ashmem and binder as modules
Bug-Debian: https://bugs.debian.org/901492
We want to enable use of the Android ashmem and binder drivers to
support Anbox, but they should not be built-in as that would waste
resources and increase security attack surface on systems that don't
need them.
- Add a MODULE_LICENSE declaration to ashmem
- Change the Makefiles to build each driver as an object with the
"_linux" suffix (which is what Anbox expects)
- Change config symbol types to tristate
Update:
In upstream commit 721412ed3d titled "staging: remove ashmem" the ashmem
driver was removed entirely. Secondary commit message:
"The mainline replacement for ashmem is memfd, so remove the legacy
code from drivers/staging/"
Consequently, the ashmem part of this patch has been removed.

Subject: dccp: Disable auto-loading as mitigation against local exploits
Forwarded: not-needed
We can mitigate the effect of vulnerabilities in obscure protocols by
preventing unprivileged users from loading the modules, so that they
are only exploitable on systems where the administrator has chosen to
load the protocol.
The 'dccp' protocol is not actively maintained or widely used.
Therefore disable auto-loading.

Subject: firmware_loader: Log direct loading failures as info for d-i
Date: Thu, 30 May 2024 13:14:32 +0100
Forwarded: not-needed
On an installed Debian system, firmware packages will normally be
installed automatically based on a mapping of device IDs to firmware.
Within the Debian installer this has not yet happened and we need a
way to detect missing firmware.
Although many/most drivers log firmware loading failures, they do so
using many different formats. This adds a single log message to the
firmware loader, which the installer's hw-detect package will look
for. The log level is set to "info" because some failures are
expected and we do not want to confuse users with bogus error messages
(like in bug #966218).
NOTE: The log message format must not be changed without coordinating
this with the check-missing-firmware.sh in hw-detect.

From: Josh Poimboeuf <jpoimboe@redhat.com>
Date: Thu, 14 Jan 2021 16:32:42 -0600
Subject: objtool: Don't fail the kernel build on fatal errors
[ Upstream commit 655cf86548a3938538642a6df27dd359e13c86bd ]
This is basically a revert of commit 644592d32837 ("objtool: Fail the
kernel build on fatal errors").
That change turned out to be more trouble than it's worth. Failing the
build is an extreme measure which sometimes gets too much attention and
blocks CI build testing.
These fatal-type warnings aren't yet as rare as we'd hope, due to the
ever-increasing matrix of supported toolchains/plugins and their
fast-changing nature as of late.
Also, there are more people (and bots) looking for objtool warnings than
ever before, so even non-fatal warnings aren't likely to be ignored for
long.

Subject: [PATCH] mac80211: avoid crashing on invalid band info
Frequent crashes have been observed on MT7916 based platforms. While the
root of these crashes are currently unknown, they happen when decoding
rate information of connected STAs in AP mode. The rate-information is
associated with a band which is not available on the PHY.
Check for this condition in order to avoid crashing the whole system.
This patch should be removed once the roout cause has been found and
fixed.

Subject: [PATCH] mac80211: sta: randomize BA session dialog token allocator
We currently always start the dialog token generator at zero,
so the first dialog token we use is always 1. This would be
OK if we had a perfect guarantee that we always do a proper
deauth/re-auth handshake, but in IBSS mode this doesn't always
happen properly.
To make problems with block ack (aggregation) sessions getting
stuck less likely, randomize the dialog token so if we start a
new session but the peer still has old state for us, it can
better detect this.
This is really just a workaround to make things a bit more
robust than they are now - a better fix would be to do a full
authentication handshake in IBSS mode upon having discovered a
new station, and on the receiver resetting the state (removing
and re-adding the station) on receiving the authentication
packet.

Subject: [PATCH] mac80211: minstrel_ht: reduce fluctuations in rate
probability stats
In some scenarios when there is a lot of fluctuation in packet error rates,
rate switching can be amplified when the statistics get skewed by time slots
with very few tries.
Make the input data to the moving average more smooth by adding the
success/attempts count from the last stats window as well. This has the
advantage of smoothing the data without introducing any extra lag to sampling
rates.
This significantly improves rate stability on a strong test link subjected to
periodic noise bursts generated with a SDR

Subject: [PATCH] mac80211: minstrel_ht: rework rate downgrade code and
max_prob rate selection
The current fallback code for fast rate switching on potentially failing rates
is triggering too often if there is some strong noise on the channel. This can
lead to wild fluctuations in the rate selection.
Additionally, switching down to max_prob_rate can create a significant gap down
in throughput, especially when using only 2 spatial streams, because max_prob_rate
is limited to using fewer streams than the max_tp rates.
In order to improve throughput without reducing reliability too much, use the
rate downgrade code for the max_prob_rate only, and allow the non-downgraded
max_prob_rate to use as many spatial streams as the max_tp rates

Subject: [PATCH] sched: sch_cake: fix bulk flow accounting logic for host
fairness
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In sch_cake, we keep track of the count of active bulk flows per host,
when running in dst/src host fairness mode, which is used as the
round-robin weight when iterating through flows. The count of active
bulk flows is updated whenever a flow changes state.
This has a peculiar interaction with the hash collision handling: when a
hash collision occurs (after the set-associative hashing), the state of
the hash bucket is simply updated to match the new packet that collided,
and if host fairness is enabled, that also means assigning new per-host
state to the flow. For this reason, the bulk flow counters of the
host(s) assigned to the flow are decremented, before new state is
assigned (and the counters, which may not belong to the same host
anymore, are incremented again).
Back when this code was introduced, the host fairness mode was always
enabled, so the decrement was unconditional. When the configuration
flags were introduced the *increment* was made conditional, but
the *decrement* was not. Which of course can lead to a spurious
decrement (and associated wrap-around to U16_MAX).
AFAICT, when host fairness is disabled, the decrement and wrap-around
happens as soon as a hash collision occurs (which is not that common in
itself, due to the set-associative hashing). However, in most cases this
is harmless, as the value is only used when host fairness mode is
enabled. So in order to trigger an array overflow, sch_cake has to first
be configured with host fairness disabled, and while running in this
mode, a hash collision has to occur to cause the overflow. Then, the
qdisc has to be reconfigured to enable host fairness, which leads to the
array out-of-bounds because the wrapped-around value is retained and
used as an array index. It seems that syzbot managed to trigger this,
which is quite impressive in its own right.
This patch fixes the issue by introducing the same conditional check on
decrement as is used on increment.
The original bug predates the upstreaming of cake, but the commit listed
in the Fixes tag touched that code, meaning that this patch won't apply
before that.
Fixes: 712639929912 ("sch_cake: Make the dual modes fairer")

Subject: cpufreq/amd-pstate: Remove the unnecessary cpufreq_update_policy call
The update_limits callback is only called in two conditions.
* When the preferred core rankings change. In which case, we just need to
change the prefcore ranking in the cpudata struct. As there are no changes
to any of the perf values, there is no need to call cpufreq_update_policy()
* When the _PPC ACPI object changes, i.e. the highest allowed Pstate
changes. The _PPC object is only used for a table based cpufreq driver
like acpi-cpufreq, hence is irrelevant for CPPC based amd-pstate.
Hence, the cpufreq_update_policy() call becomes unnecessary and can be
removed.

Subject: cpufreq/amd-pstate: Remove the unncecessary driver_lock in
amd_pstate_update_limits
There is no need to take a driver wide lock while updating the
highest_perf value in the percpu cpudata struct. Hence remove it.

Subject: cpufreq/amd-pstate: Fix the clamping of perf values
The clamping in freq_to_perf() is broken right now, as we first typecast
(read wraparound) the overflowing value into a u8 and then clamp it down.
So, use a u32 to store the >255 value in certain edge cases and then clamp
it down into a u8.
Also, use a "explicit typecast + clamp" instead of just a "clamp_t" as the
latter typecasts first and then clamps between the limits, which defeats
our purpose.

Subject: cpufreq/amd-pstate: Show a warning when a CPU fails to setup
I came across a system that MSR_AMD_CPPC_CAP1 for some CPUs isn't
populated. This is an unexpected behavior that is most likely a
BIOS bug. In the event it happens I'd like users to report bugs
to properly root cause and get this fixed.

Use the perf_to_freq helpers to calculate this on the fly.

amd_pstate_epp_update_limit() to avoid unnecessary calls in
amd_pstate_update_min_max_limit().

Subject: cpufreq/amd-pstate: Move perf values into a union
By storing perf values in a union all the writes and reads can
be done atomically, removing the need for some concurrency protections.
While making this change, also drop the cached frequency values,
using inline helpers to calculate them on demand from perf value.

Subject: cpufreq/amd-pstate: Overhaul locking
amd_pstate_cpu_boost_update() and refresh_frequency_limits() both
update the policy state and have nothing to do with the amd-pstate
driver itself.
A global "limits" lock doesn't make sense because each CPU can have
policies changed independently. Each time a CPU changes values they
will atomically be written to the per-CPU perf member. Drop per CPU
locking cases.
The remaining "global" driver lock is used to ensure that only one
entity can change driver modes at a given time.

Subject: cpufreq/amd-pstate-ut: Drop SUCCESS and FAIL enums
Enums are effectively used as a boolean and don't show
the return value of the failing call.
Instead of using enums switch to returning the actual return
code from the unit test.

Subject: cpufreq/amd-pstate-ut: Run on all of the correct CPUs
If a CPU is missing a policy or one has been offlined then the unit test
is skipped for the rest of the CPUs on the system.
Instead; iterate online CPUs and skip any missing policies to allow
continuing to test the rest of them.

Subject: cpufreq/amd-pstate: Cache CPPC request in shared mem case too
In order to prevent a potential write for shmem_update_perf()
cache the request into the cppc_req_cached variable normally only
used for the MSR case.
This adds symmetry into the code and potentially avoids extra writes.

Subject: cpufreq/amd-pstate: Move all EPP tracing into *_update_perf and
*_set_epp functions
The EPP tracing is done by the caller today, but this precludes the
information about whether the CPPC request has changed.
Move it into the update_perf and set_epp functions and include information
about whether the request has changed from the last one.
amd_pstate_update_perf() and amd_pstate_set_epp() now require the policy
as an argument instead of the cpudata.

Subject: cpufreq/amd-pstate: Rework CPPC enabling
The CPPC enable register is configured as "write once". That is
any future writes don't actually do anything.
Because of this, all the cleanup paths that currently exist for
CPPC disable are non-effective.
Rework CPPC enable to only enable after all the CAP registers have
been read to avoid enabling CPPC on CPUs with invalid _CPC or
unpopulated MSRs.
As the register is write once, remove all cleanup paths as well.

Subject: cpufreq/amd-pstate: Stop caching EPP
EPP values are cached in the cpudata structure per CPU. This is needless
though because they are also cached in the CPPC request variable.
Drop the separate cache for EPP values and always reference the CPPC
request variable when needed.

Subject: cpufreq/amd-pstate: Drop actions in amd_pstate_epp_cpu_offline()
When the CPU goes offline there is no need to change the CPPC request
because the CPU will go into the deepest C-state it supports already.
Actually changing the CPPC request when it goes offline messes up the
cached values and can lead to the wrong values being restored when
it comes back.
Instead drop the actions and if the CPU comes back online let
amd_pstate_epp_set_policy() restore it to expected values.

Subject: crypto: x86/aes-xts - make the fast path 64-bit specific
Remove 32-bit support from the fast path in xts_crypt(). Then optimize
it for 64-bit, and simplify the code, by switching to sg_virt() and
removing the now-unnecessary checks for crossing a page boundary.
The result is simpler code that is slightly smaller and faster in the
case that actually matters (64-bit).

Subject: Kunit to check the longest symbol length
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The longest length of a symbol (KSYM_NAME_LEN) was increased to 512
in the reference [1]. This patch adds kunit test suite to check the longest
symbol length. These tests verify that the longest symbol length defined
is supported.
This test can also help other efforts for longer symbol length,
like [2].
The test suite defines one symbol with the longest possible length.
The first test verify that functions with names of the created
symbol, can be called or not.
The second test, verify that the symbols are created (or
not) in the kernel symbol table.

After commit c104c16073b7 ("Kunit to check the longest symbol length"),
there is a warning when building with clang because there is now a
definition of unlikely from compiler.h in tools/include/linux, which
conflicts with the one in the instruction decoder selftest:
arch/x86/tools/insn_decoder_test.c:15:9: warning: 'unlikely' macro redefined [-Wmacro-redefined]
Remove the second unlikely() definition, as it is no longer necessary,
clearing up the warning.

Subject: mm/khugepaged: fix race with folio split/free using temporary
reference
hpage_collapse_scan_file() calls is_refcount_suitable(), which in turn
calls folio_mapcount(). folio_mapcount() checks folio_test_large() before
proceeding to folio_large_mapcount(), but there is a race window where the
folio may get split/freed between these checks, triggering:
VM_WARN_ON_FOLIO(!folio_test_large(folio), folio)
Take a temporary reference to the folio in hpage_collapse_scan_file().
This stabilizes the folio during refcount check and prevents incorrect
large folio detection due to concurrent split/free. Use helper
folio_expected_ref_count() + 1 to compare with folio_ref_count() instead
of using is_refcount_suitable().

Subject: wifi: ath12k: Abort scan before removing link interface to prevent
duplicate deletion
Currently, when ath12k performs the remove link interface operation, if
there is an ongoing scan operation on the arvif, ath12k may execute the
remove link interface operation multiple times on the same arvif. This
occurs because, during the remove link operation, if a scan operation is
present on the arvif, ath12k may receive a WMI_SCAN_EVENT_COMPLETED event
from the firmware. Upon receiving this event, ath12k will continue to
execute the ath12k_scan_vdev_clean_work() function, performing the remove
link interface operation on the same arvif again.
To address this issue, before executing the remove link interface
operation, ath12k needs to check if there is an ongoing scan operation on
the current arvif. If such an operation exists, it should be aborted.

Subject: Kconfig: switch CONFIG_SYSFS_SYCALL default to n
This odd system call will be removed in the future. Let's decouple it
from CONFIG_EXPERT and switch the default to n as a first step.

Subject: mm: add folio_expected_ref_count() for reference count calculation
Patch series " JFS: Implement migrate_folio for jfs_metapage_aops" v5.
This patchset addresses a warning that occurs during memory compaction due
to JFS's missing migrate_folio operation. The warning was introduced by
commit 7ee3647243e5 ("migrate: Remove call to ->writepage") which added
explicit warnings when filesystem don't implement migrate_folio.
The syzbot reported following [1]:
jfs_metapage_aops does not implement migrate_folio

To fix this issue, this series implement metapage_migrate_folio() for JFS
which handles both single and multiple metapages per page configurations.
While most filesystems leverage existing migration implementations like
filemap_migrate_folio(), buffer_migrate_folio_norefs() or
buffer_migrate_folio() (which internally used folio_expected_refs()),
JFS's metapage architecture requires special handling of its private data
during migration. To support this, this series introduce the
folio_expected_ref_count(), which calculates external references to a
folio from page/swap cache, private data, and page table mappings.
This standardized implementation replaces the previous ad-hoc
folio_expected_refs() function and enables JFS to accurately determine
whether a folio has unexpected references before attempting migration.
Implement folio_expected_ref_count() to calculate expected folio reference
counts from:
- Page/swap cache (1 per page)
- Private data (1)
- Page table mappings (1 per map)
While originally needed for page migration operations, this improved
implementation standardizes reference counting by consolidating all
refcount contributors into a single, reusable function that can benefit
any subsystem needing to detect unexpected references to folios.
The folio_expected_ref_count() returns the sum of these external
references without including any reference the caller itself might hold.
Callers comparing against the actual folio_ref_count() must account for
their own references separately.

Subject: drm/i915/snps_hdmi_pll: Fix 64-bit divisor truncation by using
div64_u64
DIV_ROUND_CLOSEST_ULL uses do_div(), which expects a 32-bit divisor.
When passing a 64-bit constant like CURVE2_MULTIPLIER, the value is
silently truncated to u32, potentially leading to incorrect results
on large divisors.
Replace DIV_ROUND_CLOSEST_ULL with div64_u64(), which correctly
handles full 64-bit division. Since the result is clamped between
1 and 127, rounding is unnecessary and truncating division
is sufficient.
