6c45a5a7e1 platform/x86: intel_telemetry: Fix PSS event register mask
[ Upstream commit 39e9c376ac ]

The PSS telemetry info parsing incorrectly applies
TELEM_INFO_SRAMEVTS_MASK when extracting event register
count from firmware response. This reads bits 15-8 instead
of the correct bits 7-0, causing misdetection of hardware
capabilities.

The IOSS path correctly uses TELEM_INFO_NENABLES_MASK for
register count. Apply the same mask to PSS parsing for
consistency.

f93ae43780 platform/x86: toshiba_haps: Fix memory leaks in add/remove routines
[ Upstream commit 1284974567 ]

toshiba_haps_add() leaks the haps object allocated by it if it returns
an error after allocating that object successfully.

toshiba_haps_remove() does not free the object pointed to by
toshiba_haps before clearing that pointer, so it becomes unreachable
allocated memory.

Address these memory leaks by using devm_kzalloc() for allocating
the memory in question.

245ff08e26 Revert "drm/amd/display: pause the workload setting in dm"
[ Upstream commit f377ea0561 ]

This reverts commit bc6d54ac7e.

The workload profile needs to be in the default state when
the dc idle optimizaion state is entered.  However, when
jobs come in for video or GFX or compute, the profile may
be set to a non-default profile resulting in the dc idle
optimizations not taking affect and resulting in higher
power usage.  As such we need to pause the workload profile
changes during this transition.  When this patch was originally
committed, it caused a regression with a Dell U3224KB display,
but no other problems were reported at the time.  When it
was reapplied (this patch) to address increased power usage, it
seems to have caused additional regressions.  This change seems
to have a number of side affects (audio issues, stuttering,
etc.).  I suspect the pause should only happen when all displays
are off or in static screen mode, but I think this call site
gets called more often than that which results in idle state
entry more often than intended.  For now revert.

98bf5bc8cb tracing: Avoid possible signed 64-bit truncation
[ Upstream commit 00f13e28a9 ]

64-bit truncation to 32-bit can result in the sign of the truncated
value changing. The cmp_mod_entry is used in bsearch and so the
truncation could result in an invalid search order. This would only
happen were the addresses more than 2GB apart and so unlikely, but
let's fix the potentially broken compare anyway.

6dd87f6afe ALSA: hda/realtek: ALC269 fixup for Lenovo Yoga Book 9i 13IRU8 audio
[ Upstream commit 64e0924ed3 ]

The amp/speakers on the Lenovo Yoga Book 9i 13IRU8 laptop aren't
fully powered up, resulting in horrible tinny sound by default.

The kernel has an existing quirk for PCI SSID 0x17aa3843 which
matches this machine and several others. The quirk applies the
ALC287_FIXUP_IDEAPAD_BASS_SPK_AMP fixup, however the fixup does not
work on this machine.

This patch modifies the existing quirk by adding a check for the
subsystem ID 0x17aa3881. If present, ALC287_FIXUP_TAS2781_I2C will
be applied instead of ALC287_FIXUP_IDEAPAD_BASS_SPK_AMP. With this
change the TAS2781 amp is powered up, firmware is downloaded and
recognised by HDA/SOF - i.e. all is good, and we can boogie.

Code is re-used from alc298_fixup_lenovo_c940_duet7(), which fixes a
similar problem with two other Lenovo laptops.

Cross checked against ALSA cardinfo database for potential clashes.
Tested against 6.18.5 kernel built with Arch Linux default options.
Tested in HDA mode and SOF mode.

Note: Possible further work required to address quality of life issues
caused by the firmware's agressive power saving, and to improve ALSA
control mappings.

Since rescue mount options will mark the full fs read-only, there should
be no new transaction triggered.

But during unmount we will evict all inodes, which can trigger a new
transaction, and triggers warnings on a heavily corrupted fs.

[CAUSE]
Btrfs allows new transaction even on a read-only fs, this is to allow
log replay happen even on read-only mounts, just like what ext4/xfs do.

However with rescue mount options, the fs is fully read-only and cannot
be remounted read-write, thus in that case we should also reject any new
transactions.

[FIX]
If we find the fs has rescue mount options, we should treat the fs as
error, so that no new transaction can be started.

b4b065a880 wifi: mac80211: don't increment crypto_tx_tailroom_needed_cnt twice
[ Upstream commit 3f3d8ff314 ]

In reconfig, in case the driver asks to disconnect during the reconfig,
all the keys of the interface are marked as tainted.
Then ieee80211_reenable_keys will loop over all the interface keys, and
for each one it will
a) increment crypto_tx_tailroom_needed_cnt
b) call ieee80211_key_enable_hw_accel, which in turn will detect that
this key is tainted, so it will mark it as "not in hardware", which is
paired with crypto_tx_tailroom_needed_cnt incrementation, so we get two
incrementations for each tainted key.
Then we get a warning in ieee80211_free_keys.

To fix it, don't increment the count in ieee80211_reenable_keys for
tainted keys

ccb3c75d57 btrfs: sync read disk super and set block size
[ Upstream commit 3f29d661e5 ]

When the user performs a btrfs mount, the block device is not set
correctly. The user sets the block size of the block device to 0x4000
by executing the BLKBSZSET command.
Since the block size change also changes the mapping->flags value, this
further affects the result of the mapping_min_folio_order() calculation.

Let's analyze the following two scenarios:

Scenario 1: Without executing the BLKBSZSET command, the block size is
0x1000, and mapping_min_folio_order() returns 0;

Scenario 2: After executing the BLKBSZSET command, the block size is
0x4000, and mapping_min_folio_order() returns 2.

do_read_cache_folio() allocates a folio before the BLKBSZSET command
is executed. This results in the allocated folio having an order value
of 0. Later, after BLKBSZSET is executed, the block size increases to
0x4000, and the mapping_min_folio_order() calculation result becomes 2.

This leads to two undesirable consequences:

1. filemap_add_folio() triggers a VM_BUG_ON_FOLIO(folio_order(folio) <
mapping_min_folio_order(mapping)) assertion.

2. The syzbot report [1] shows a null pointer dereference in
create_empty_buffers() due to a buffer head allocation failure.

Synchronization should be established based on the inode between the
BLKBSZSET command and read cache page to prevent inconsistencies in
block size or mapping flags before and after folio allocation.

3835e49e14 scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()
[ Upstream commit 9411a89e9e ]

In iscsit_dec_conn_usage_count(), the function calls complete() while
holding the conn->conn_usage_lock. As soon as complete() is invoked, the
waiter (such as iscsit_close_connection()) may wake up and proceed to free
the iscsit_conn structure.

If the waiter frees the memory before the current thread reaches
spin_unlock_bh(), it results in a KASAN slab-use-after-free as the function
attempts to release a lock within the already-freed connection structure.

Fix this by releasing the spinlock before calling complete().

c65a1a72a4 riscv: Use 64-bit variable for output in __get_user_asm
[ Upstream commit bdce162f2e ]

After commit f6bff7827a ("riscv: uaccess: use 'asm_goto_output' for
get_user()"), which was the first commit that started using asm goto
with outputs on RISC-V, builds of clang built with assertions enabled
start crashing in certain files that use get_user() with:

  clang: llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp:12743: Register FollowCopyChain(MachineRegisterInfo &, Register): Assertion `MI->getOpcode() == TargetOpcode::COPY && "start of copy chain MUST be COPY"' failed.

Internally, LLVM generates an addiw instruction when the output of the
inline asm (which may be any scalar type) needs to be sign extended for
ABI reasons, such as a later function call, so that basic block does not
have to do it.

Use a temporary 64-bit variable as the output of the inline assembly in
__get_user_asm() and explicitly cast it to truncate it if necessary,
avoiding the addiw that triggers the assertion.

[ Upstream commit 84dc603739 ]

In iscsit_dec_session_usage_count(), the function calls complete() while
holding the sess->session_usage_lock. Similar to the connection usage count
logic, the waiter signaled by complete() (e.g., in the session release
path) may wake up and free the iscsit_session structure immediately.

This creates a race condition where the current thread may attempt to
execute spin_unlock_bh() on a session structure that has already been
deallocated, resulting in a KASAN slab-use-after-free.

To resolve this, release the session_usage_lock before calling complete()
to ensure all dereferences of the sess pointer are finished before the
waiter is allowed to proceed with deallocation.

8a7ef96e6a wifi: cfg80211: Fix bitrate calculation overflow for HE rates
[ Upstream commit a3034bf074 ]

An integer overflow occurs in cfg80211_calculate_bitrate_he() when
calculating bitrates for high throughput HE configurations.
For example, with 160 MHz bandwidth, HE-MCS 13, HE-NSS 4, and HE-GI 0,
the multiplication (result * rate->nss) overflows the 32-bit 'result'
variable before division by 8, leading to significantly underestimated
bitrate values.

The overflow occurs because the NSS multiplication operates on a 32-bit
integer that cannot accommodate intermediate values exceeding
4,294,967,295. When overflow happens, the value wraps around, producing
incorrect bitrates for high MCS and NSS combinations.

Fix this by utilizing the 64-bit 'tmp' variable for the NSS
multiplication and subsequent divisions via do_div(). This approach
preserves full precision throughout the entire calculation, with the
final value assigned to 'result' only after completing all operations.

7d4c9c448c spi: hisi-kunpeng: Fixed the wrong debugfs node name in hisi_spi debugfs initialization
[ Upstream commit b062a899c9 ]

In hisi_spi_debugfs_init, spi controller pointer is calculated
by container_of macro, and the member is hs->dev. But the host
cannot be calculated offset directly by this. (hs->dev) points
to (pdev->dev), and it is the (host->dev.parent) rather than
(host->dev) points to the (pdev->dev), which is set in
__spi_alloc_controller.

In this patch, this issues is fixed by getting the spi_controller
data from pdev->dev by dev_get_drvdata() directly. (dev->driver_data)
points to the spi controller data in the probe stage.

for rate 22050 / pps 1000, and packsize[0] 22 packsize[1] 23. The buffer
size for each data URB is maxpacksize * packets, which in this example
is 40 * 6 = 240; When the user performs a write operation to send audio
data into the ALSA PCM playback stream, the calculated number of frames
is packsize[0] * packets = 264, which exceeds the allocated URB buffer
size, triggering the out-of-bounds (OOB) issue reported by syzbot [1].

e810b29092 nvme-fc: release admin tagset if init fails
[ Upstream commit d1877cc727 ]

nvme_fabrics creates an NVMe/FC controller in following path:

    nvmf_dev_write()
      -> nvmf_create_ctrl()
        -> nvme_fc_create_ctrl()
          -> nvme_fc_init_ctrl()

nvme_fc_init_ctrl() allocates the admin blk-mq resources right after
nvme_add_ctrl() succeeds.  If any of the subsequent steps fail (changing
the controller state, scheduling connect work, etc.), we jump to the
fail_ctrl path, which tears down the controller references but never
frees the admin queue/tag set.  The leaked blk-mq allocations match the
kmemleak report seen during blktests nvme/fc.

Check ctrl->ctrl.admin_tagset in the fail_ctrl path and call
nvme_remove_admin_tag_set() when it is set so that all admin queue
allocations are reclaimed whenever controller setup aborts.

61fa85497c ASoC: davinci-evm: Fix reference leak in davinci_evm_probe
[ Upstream commit 5b577d214f ]

The davinci_evm_probe() function calls of_parse_phandle() to acquire
device nodes for "ti,audio-codec" and "ti,mcasp-controller". These
functions return device nodes with incremented reference counts.

However, in several error paths (e.g., when the second of_parse_phandle(),
snd_soc_of_parse_card_name(), or devm_snd_soc_register_card() fails),
the function returns directly without releasing the acquired nodes,
leading to reference leaks.

This patch adds an error handling path 'err_put' to properly release
the device nodes using of_node_put() and clean up the pointers when
an error occurs.

[ Upstream commit a143545855 ]

Add proper locking in mmp_pdma_residue() to prevent use-after-free when
accessing descriptor list and descriptor contents.

The race occurs when multiple threads call tx_status() while the tasklet
on another CPU is freeing completed descriptors:

CPU 0                              CPU 1
-----                              -----
mmp_pdma_tx_status()
mmp_pdma_residue()
  -> NO LOCK held
     list_for_each_entry(sw, ..)
                                   DMA interrupt
                                   dma_do_tasklet()
                                     -> spin_lock(&desc_lock)
                                        list_move(sw->node, ...)
                                        spin_unlock(&desc_lock)
  |                                     dma_pool_free(sw) <- FREED!
  -> access sw->desc <- UAF!

This issue can be reproduced when running dmatest on the same channel with
multiple threads (threads_per_chan > 1).

Fix by protecting the chain_running list iteration and descriptor access
with the chan->desc_lock spinlock.

b1f8285bc8 riscv: trace: fix snapshot deadlock with sbi ecall
[ Upstream commit b0d7f5f0c9 ]

If sbi_ecall.c's functions are traceable,

echo "__sbi_ecall:snapshot" > /sys/kernel/tracing/set_ftrace_filter

may get the kernel into a deadlock.

(Functions in sbi_ecall.c are excluded from tracing if
CONFIG_RISCV_ALTERNATIVE_EARLY is set.)

__sbi_ecall triggers a snapshot of the ringbuffer. The snapshot code
raises an IPI interrupt, which results in another call to __sbi_ecall
and another snapshot...

All it takes to get into this endless loop is one initial __sbi_ecall.
On RISC-V systems without SSTC extension, the clock events in
timer-riscv.c issue periodic sbi ecalls, making the problem easy to
trigger.

Always exclude the sbi_ecall.c functions from tracing to fix the
potential deadlock.

sbi ecalls can easiliy be logged via trace events, excluding ecall
functions from function tracing is not a big limitation.

151589d15e ring-buffer: Avoid softlockup in ring_buffer_resize() during memory free
[ Upstream commit 6435ffd6c7 ]

When user resize all trace ring buffer through file 'buffer_size_kb',
then in ring_buffer_resize(), kernel allocates buffer pages for each
cpu in a loop.

If the kernel preemption model is PREEMPT_NONE and there are many cpus
and there are many buffer pages to be freed, it may not give up cpu
for a long time and finally cause a softlockup.

To avoid it, call cond_resched() after each cpu buffer free as Commit
f6bd2c9248 ("ring-buffer: Avoid softlockup in ring_buffer_resize()")
does.

cd7ff7fd3e drm/amd/pm: Disable MMIO access during SMU Mode 1 reset
[ Upstream commit 0de604d035 ]

During Mode 1 reset, the ASIC undergoes a reset cycle and becomes
temporarily inaccessible via PCIe. Any attempt to access MMIO registers
during this window (e.g., from interrupt handlers or other driver threads)
can result in uncompleted PCIe transactions, leading to NMI panics or
system hangs.

To prevent this, set the `no_hw_access` flag to true immediately after
triggering the reset. This signals other driver components to skip
register accesses while the device is offline.

A memory barrier `smp_mb()` is added to ensure the flag update is
globally visible to all cores before the driver enters the sleep/wait
state.

2124279f1f HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()
[ Upstream commit 2497ff38c5 ]

`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.

The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).

The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.

Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.

The impact is low since access to hidraw devices requires root.

6456713771 drm/amd/display: Reduce number of arguments of dcn30's CalculatePrefetchSchedule()
[ Upstream commit f54a91f533 ]

After an innocuous optimization change in clang-22,
dml30_ModeSupportAndSystemConfigurationFull() is over the 2048 byte
stack limit for display_mode_vba_30.c.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (2096) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
        |      ^

With clang-21, this function was already close to the limit:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (1912) exceeds limit (1586) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
        |      ^

CalculatePrefetchSchedule() has a large number of parameters, which must
be passed on the stack. Most of the parameters between the two callsites
are the same, so they can be accessed through the existing mode_lib
pointer, instead of being passed as explicit arguments. Doing this
reduces the stack size of dml30_ModeSupportAndSystemConfigurationFull()
from 2096 bytes to 1912 bytes with clang-22.

eb5d6dedad netfilter: replace -EEXIST with -EBUSY
[ Upstream commit 2bafeb8d2f ]

The -EEXIST error code is reserved by the module loading infrastructure
to indicate that a module is already loaded. When a module's init
function returns -EEXIST, userspace tools like kmod interpret this as
"module already loaded" and treat the operation as successful, returning
0 to the user even though the module initialization actually failed.

Replace -EEXIST with -EBUSY to ensure correct error reporting in the module
initialization path.

Affected modules:
  * ebtable_broute ebtable_filter ebtable_nat arptable_filter
  * ip6table_filter ip6table_mangle ip6table_nat ip6table_raw
  * ip6table_security iptable_filter iptable_mangle iptable_nat

Hence, remove L0s support from the Root Port Link Capabilities in this SoC.

Since qcom_pcie_clear_aspm_l0s() is now used by more than one SoC config,
call it from qcom_pcie_host_init() instead.

5b9bbe3d7b x86/sev: Disable GCOV on noinstr object
[ Upstream commit 9efb74f84b ]

With Debian clang version 19.1.7 (3+build5) there are calls to
kasan_check_write() from __sev_es_nmi_complete(), which violates noinstr.  Fix
it by disabling GCOV for the noinstr object, as has been done for previous
such instrumentation issues.

Note that this file already disables __SANITIZE_ADDRESS__ and
__SANITIZE_THREAD__, thus calls like kasan_check_write() ought to be nops
regardless of GCOV. This has been fixed in other patches. However, to avoid
any other accidental instrumentation showing up, (and since, in principle GCOV
is instrumentation and hence should be disabled for noinstr code anyway),
disable GCOV overall as well.

747b9a7d4c HID: playstation: Center initial joystick axes to prevent spurious events
[ Upstream commit e9143268d2 ]

When a new PlayStation gamepad (DualShock 4 or DualSense) is initialized,
the input subsystem sets the default value for its absolute axes (e.g.,
ABS_X, ABS_Y) to 0.

However, the hardware's actual neutral/resting state for these joysticks
is 128 (0x80). This creates a mismatch.

When the first HID report arrives from the device, the driver sees the
resting value of 128. The kernel compares this to its initial state of 0
and incorrectly interprets this as a delta (0 -> 128). Consequently, it
generates EV_ABS events for this initial, non-existent movement.

This behavior can fail userspace 'sanity check' tests (e.g., in
Android CTS) that correctly assert no motion events should be generated
from a device that is already at rest.

This patch fixes the issue by explicitly setting the initial value of the
main joystick axes (e.g., ABS_X, ABS_Y, ABS_RX, ABS_RY) to 128 (0x80)
in the common ps_gamepad_create() function.

This aligns the kernel's initial state with the hardware's expected
neutral state, ensuring that the first report (at 128) produces no
delta and thus, no spurious event.

7ae5b35148 HID: intel-ish-hid: Reset enum_devices_done before enumeration
[ Upstream commit 56e230723e ]

Some systems have enabled ISH without any sensors. In this case sending
HOSTIF_DM_ENUM_DEVICES results in 0 sensors. This triggers ISH hardware
reset on subsequent enumeration after S3/S4 resume.

The enum_devices_done flag was not reset before sending the
HOSTIF_DM_ENUM_DEVICES command. On subsequent enumeration calls (such as
after S3/S4 resume), this flag retains its previous true value, causing the
wait loop to be skipped and returning prematurely to hid_ishtp_cl_init().
If 0 HID devices are found, hid_ishtp_cl_init() skips getting HID device
descriptors and sets init_done to true. When the delayed enumeration
response arrives with init_done already true, the driver treats it as a bad
packet and triggers an ISH hardware reset.

Set enum_devices_done to false before sending the enumeration command,
consistent with similar functions like ishtp_get_hid_descriptor() and
ishtp_get_report_descriptor() which reset their respective flags.
