462775c620 ata: libata-core: Add NOLPM quirk for PNY CS900 1TB SSD
The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus
after entering Device-Initiated Slumber during idle. With the default
med_power_with_dipm policy the link goes down (SStatus 1 SControl 300)
and does not recover, forcing the filesystem read-only. Forcing
max_performance keeps the link stable across prolonged idle.

Add a NOLPM quirk so link power management is disabled for this drive
specifically, leaving it intact for other devices on the host.

d1ceb2b232 platform/chrome: sensorhub: Fix memory overread in ring handler
`max_response` and `sensor_num` are read from different EC commands:

- `max_response` is from cros_ec_get_proto_info().
    ec_dev->max_response = info->max_response_packet_size -
                                    sizeof(struct ec_host_response);

- `sensor_num` is from cros_ec_get_sensor_count().
    sensor_num = cros_ec_get_sensor_count(ec);

With a malfunctioning EC firmware, it is possible that the `msg->insize`
(i.e., `fifo_info_length` in the context) could be clamped in
cros_ec_cmd_xfer() because `msg->insize` is greater than `max_response`.

    int fifo_info_length =
            sizeof(struct ec_response_motion_sense_fifo_info) +
            sizeof(u16) * sensorhub->sensor_num;

This means the number of read bytes could be less than expected.  As a
result, the subsequent memcpy() in cros_ec_sensorhub_ring_handler()
overreads the `resp->fifo_info` buffer.

Check the return value of cros_ec_cmd_xfer_status() and abort if the
number of bytes read does not match the expected length.

a1735eae55 nilfs2: reject invalid block index in GC ioctl
Syzbot reported list corruption caused by a double list_add_tail() call on
bh->b_assoc_buffers within nilfs_lookup_dirty_data_buffers().

Analysis revealed that the root cause was the insertion of a page/folio
with a page index of ULONG_MAX into the page cache via the GC ioctl.
filemap_get_folios_tag(), called by nilfs_lookup_dirty_data_buffers(),
repeatedly detects a dirty folio with a page index of ULONG_MAX due to
index wrap-around, leading to duplicate processing of dirty buffers.

As a preparatory step, the GC ioctl loads the page/folio of the block to
be moved during GC and inserts it into the page cache based on information
in the nilfs_vdesc structure passed as an argument.  Normally, this does
not cause issues because the user-space GC library configures the
nilfs_vdesc structure properly.  However, since there is no range check on
the parameters determining the page index, a request with artificially
crafted parameters -- such as those generated by Syzbot -- can result in a
page/folio being inserted with a page index of ULONG_MAX, triggering the
above problem.

This resolves the issue by checking the ranges of 'vd_offset' and
'vd_vblocknr' in the nilfs_vdesc structure that determine the page index,
thereby preventing the invalid page/folio insertions.

d7b2769f8d selftests/rseq: Replace glibc-specific __GNUC_PREREQ with portable check
Building the rseq selftests against musl libc fails because musl's
<features.h> does not provide the glibc-specific __GNUC_PREREQ macro:

  error: missing binary operator before token '('

Replace __GNUC_PREREQ(11, 1) with an equivalent check using __GNUC__
and __GNUC_MINOR__ directly.  This pattern is portable across all C
library implementations and is already used elsewhere in the tools/
tree (e.g., tools/include/linux/string.h).

This also allows removing the #include <features.h>, which was only
needed for __GNUC_PREREQ.

abb81e5ce7 csky: Fix a4/a5 restoration in syscall trace path
The syscall trace path reloads syscall arguments from pt_regs before
calling the syscall handler. On C-SKY ABIv2, the 5th and 6th syscall
arguments are prepared as stack arguments before invoking syscallid.

The current code adjusts sp before loading LSAVE_A4 and LSAVE_A5. Since
those offsets are relative to the original pt_regs base, loading them
after changing sp fetches the wrong slots. As a result, traced syscalls
that use the 5th or 6th argument may receive corrupted arguments.

This is visible with mmap2(), which takes six arguments. A small
PTRACE_SYSCALL reproducer opens a file and maps one page with:

  mmap(NULL, 4096, PROT_READ | PROT_EXEC, MAP_PRIVATE, fd, 0)

Before the fix, the traced child fails the mmap and exits with 12.
After the fix, the mapping succeeds and the child exits with 0.

Fix the trace path by loading a4/a5 from pt_regs before changing sp.

Tested on: ck860f, linux-4.19.15, C-SKY abiv2

e8d85672dd wifi: ath11k: fix NULL pointer dereference in ath11k_hal_srng_access_begin
In ATH11K_QMI_EVENT_FW_READY, ATH11K_FLAG_REGISTERED is set
unconditionally even when ath11k_core_qmi_firmware_ready() fails.
This leaves the driver in an inconsistent state where
initialization is considered complete although the firmware ready
handling did not finish successfully. During the subsequent SSR,
the driver enters the restart path based on this incorrect state
and dereferences uninitialized srng members, resulting in a NULL
pointer dereference.

Call trace:
  ath11k_hal_srng_access_begin+0xc/0x60 [ath11k] (P)
  ath11k_ce_cleanup_pipes+0x17c/0x180 [ath11k]
  ath11k_core_restart+0x40/0x168 [ath11k]

Fix this by:
- skipping firmware_ready if ATH11K_FLAG_REGISTERED is already set
- setting ATH11K_FLAG_REGISTERED only when firmware_ready succeeds
- setting ATH11K_FLAG_QMI_FAIL and aborting the FW_READY handling
on error

ba7debb4dd wifi: ath6kl: fix use-after-free in aggr_reset_state()
The aggr_reset_state() function uses timer_delete() (non-synchronous)
for the aggregation timer before proceeding to delete TID state and
before the structure is freed by callers like aggr_module_destroy().

If the timer callback (aggr_timeout) is executing when aggr_reset_state()
is called, the callback will continue to access aggr_conn fields like
rx_tid[] and stat[] which may be freed immediately after by
kfree(aggr_info->aggr_conn) in aggr_module_destroy().

Additionally, the timer callback can re-arm itself via mod_timer() while
aggr_reset_state() is running, creating a more complex race condition.

Use timer_delete_sync() instead to ensure any running timer callback
has completed before returning.

dad9f96945 wifi: ath9k: hif_usb: don't dereference hif_dev after re-arming firmware request
ath9k_hif_request_firmware() re-arms an asynchronous firmware load via
request_firmware_nowait(), passing hif_dev as the completion context, and
then still dereferences hif_dev:

	dev_info(&hif_dev->udev->dev, "ath9k_htc: Firmware %s requested\n",
		 hif_dev->fw_name);

The re-armed callback ath9k_hif_usb_firmware_cb() runs on the "events"
workqueue and, when the firmware is missing, walks the retry chain into
ath9k_hif_usb_firmware_fail() -> complete_all(&hif_dev->fw_done). That
releases the wait_for_completion(&hif_dev->fw_done) in a concurrent
ath9k_hif_usb_disconnect(), which then kfree()s hif_dev. The trailing
dev_info() in the frame that re-armed the request can therefore read freed
memory (hif_dev->udev, the first field of struct hif_device_usb):

  BUG: KASAN: slab-use-after-free in ath9k_hif_request_firmware
  Read of size 8 ... by task kworker/...
   ath9k_hif_request_firmware
   ath9k_hif_usb_firmware_cb           drivers/net/wireless/ath/ath9k/hif_usb.c:1247

  Freed by ...:
   ath9k_hif_usb_disconnect -> kfree   drivers/net/wireless/ath/ath9k/hif_usb.c

The fw_done barrier only makes disconnect wait for the firmware chain to
*terminate*; it does not protect the outer ath9k_hif_request_firmware()
frame that re-armed the request and keeps touching hif_dev afterwards.

Drop the post-request dev_info(): it is the only use of hif_dev after the
async request is armed, and it is purely informational (the dev_err() on the
failure path runs only when request_firmware_nowait() did not arm a callback,
so hif_dev is still alive there).

This was first reported by syzbot as a single, non-reproduced crash that was
later auto-obsoleted, and was independently rediscovered by the reFuzz fuzzer,
which produced a C reproducer (USB-gadget connect/disconnect of an ath9k_htc
device whose firmware download fails). The vulnerable code is unchanged and
still present in v7.1-rc6, where the slab-use-after-free reproduces under KASAN
once the (sub-microsecond) race window is widened.

39def6d250 futex/requeue: Revert "Prevent NULL pointer dereference in remove_waiter() on self-deadlock""
The commit cited below should not have been merged. It attemted to fix an
existing problem ansd thereby introduced new problems by keeping the
pi_state in state Q_REQUEUE_PI_IN_PROGRESS and leaking it.

Based on the commit description the intention was to handle the case
when task_blocks_on_rt_mutex() returns -EDEADLK and the following
remove_waiter() dereferences the NULL pointer in waiter->task.

That is already handled by Davidlohr in commit 40a25d59e8
("locking/rtmutex: Skip remove_waiter() when waiter is not enqueued") and
requires no further acting.

Revert the commit breaking the "waiter == owner" case again.

The default msi-map from sm8550.dtsi is deleted for both pcie0 and
pcie1. The QPS615 PCIe switch on each port exposes more than two
devices (1 USP + 3 DSPs), but Gunyah currently limits ITS device
mappings to two per root complex to save memory. With msi-map
present, the ITS MAPD command times out.

Deleting msi-map causes the DWC controller to fall back to its
internal iMSI-RX module, which handles MSIs without this limitation.

board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.

Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:

3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.

batman-adv: fix VLAN priority offset
The batadv_skb_set_priority() receives an SKB with the inner ethernet
header at position "offset". When it tries to extract the IPv4 and IPv6
header, it needs to skip the ethernet header to get access to the IP
header.

But for VLAN header, it performs the access with the struct vlan_ethhdr.
This struct contains both both the ethernet header and the VLAN header. It
is therefore incorrect to skip over the whole vlan_ethhdr size to get
access to the vlan_ethhdr.

993555b547 arm64: dts: rockchip: Add AP6275S support for 9Tripod X3568 v4
Add the missing Broadcom Wi-Fi and Bluetooth child nodes for the
9Tripod X3568 v4 board.

The Bluetooth subnode is attached to uart8 with hardware flow control
enabled via RTS/CTS pins.

The Wi-Fi subnode is connected via the sdmmc2 bus.

Additionally, change the status of the i2s3_2ch node to "disabled"
since the required rk3568-codec-digital driver for Bluetooth audio
is currently unavailable in the mainline tree.

ASoC: rsnd: src: Add missing scu_supply clock to suspend/resume
scu_supply is enabled alongside scu and scu_x2 during normal SRC
operation, but rsnd_src_suspend() and rsnd_src_resume() only disable
and re-enable scu and scu_x2. The supply clock is left enabled across
a system suspend and its prepare/enable refcount becomes unbalanced
after a suspend/resume cycle.

Disable scu_supply in rsnd_src_suspend() and re-enable it in
rsnd_src_resume() so the SRC clocks are managed consistently across
system PM transitions.

The 'gpio' property for fixed regulators has been deprecated in favor
of the plural 'gpios' form according to the regulator-fixed binding.

Update the USB host and USB OTG fixed regulators for the 9Tripod X3568 v4

regulator: max8998_pmic_dt_parse_pdata: of_node_put on reg_np after ownership transferred to rdata
In max8998_pmic_dt_parse_pdata(), of_get_child_by_name() acquires a
reference on reg_np which is then stored in rdata->reg_node, transferring
ownership to the regulator data array. The subsequent of_node_put(reg_np)
at the end of the function releases the last matched regulator node's
reference, leaving rdata->reg_node as a dangling pointer for the last
entry.

Remove the spurious of_node_put(reg_np) call.

bb27fcc67c RDMA/siw: publish QP after initialization
siw_create_qp() currently calls siw_qp_add() before the queues, CQ
pointers, state, completion, and device list entry are ready. A QPN
lookup can therefore reach a QP that is still being constructed.

Move siw_qp_add() to the end of siw_create_qp(), after QP
initialization and before adding the QP to the siw device list.

63bbf9ac5d accel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap()
When vm_insert_pages() fails, the error path calls vma->vm_ops->close(vma)
which internally calls drm_gem_vm_close() → drm_gem_object_put(),
releasing the GEM object reference acquired at the start of the function.
However, the close_vma label then falls through to put_obj, which calls
drm_gem_object_put() a second time on the same object.

If the first put releases the last reference, the object is freed and the
second put accesses freed memory, causing a use-after-free.

Fix by returning directly from close_vma instead of falling through to
put_obj, since the close handler already performs all necessary cleanup
including the object put.

9f0f2d2121 RDMA/hns: Fix potential integer overflow in mhop hem cleanup
In hns_roce_cleanup_mhop_hem_table(), the expression:

    obj = i * buf_chunk_size / table->obj_size;

is evaluated using 32-bit unsigned arithmetic because
'buf_chunk_size' is u32 and the usual arithmetic conversions convert
'i' to unsigned int. The result is assigned to a u64 variable, but the
multiplication may overflow before the assignment.

For sufficiently large HEM tables, this produces an incorrect object
index passed to hns_roce_table_mhop_put().

Cast 'i' to u64 before the multiplication so that the intermediate
calculation is performed with 64-bit arithmetic.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

b9b0889071 RDMA/irdma: Prevent user-triggered null deref on QP create
Previously, the user QP creation path would only attempt to
populate iwqp->iwpbl if the user-provided req.user_wqe_bufs
field was non-zero. The problem is that iwqp->iwpbl is
unconditionally dereferenced later on in irdma_setup_virt_qp.

While there was a check for iwqp->iwpbl != NULL, this check
would only occur if req.user_wqe_bufs was non-zero. The end
result is that a user could send a zero user_wqe_bufs value
and trigger a null ptr deref.

Fix this by unconditionally calling irdma_get_pbl and bailing
if it fails, similar to the CQ and SRQ paths.
