RDMA/bnxt_re: Fix OOB write in bnxt_re_copy_err_stats()

Commit ef56081d1864 ("RDMA/bnxt_re: RoCE related hardware counters
update") added three new counters and placed them after
BNXT_RE_OUT_OF_SEQ_ERR.

BNXT_RE_OUT_OF_SEQ_ERR acts as a boundary marker for allocating hardware
statistics with different num_counters values on chip_gen_p5_p7 devices.

As a result, BNXT_RE_NUM_STD_COUNTERS are used when allocating
hw_stats, which leads to an out-of-bounds write in
bnxt_re_copy_err_stats().

The counters BNXT_RE_REQ_CQE_ERROR, BNXT_RE_RESP_CQE_ERROR, and
BNXT_RE_RESP_REMOTE_ACCESS_ERRS are applicable to generic hardware, not
only p5/p7 devices.

Fix this by moving these counters before BNXT_RE_OUT_OF_SEQ_ERR so they
are included in the generic counter set.

multiple flags (e.g. IB_SEND_SIGNALED | IB_SEND_IP_CSUM), while the
existing code uses a switch() statement that only matches when
send_flags is exactly IB_SEND_IP_CSUM.

As a result, checksum offload is not enabled when additional SEND
flags are present.

Replace the switch() with a bitmask test:

    if (wr->send_flags & IB_SEND_IP_CSUM)

RDMA/rxe: let rxe_reclassify_recv_socket() call sk_owner_put()

On kernels build with CONFIG_PROVE_LOCKING, CONFIG_MODULES
and CONFIG_DEBUG_LOCK_ALLOC 'rmmod rdma_rxe' is no longer
possible.

For the global recv sockets rxe_net_exit() is where we
call rxe_release_udp_tunnel-> udp_tunnel_sock_release(),
which means the sockets are destroyed before 'rmmod rdma_rxe'
finishes, so there's no need to protect against
rxe_recv_slock_key and rxe_recv_sk_key disappearing
while the sockets are still alive.

x86/irqflags: Use ASM_OUTPUT_RM in native_save_fl()

clang is generating very inefficient code for native_save_fl() which is
used for local_irq_save() in critical spots.

Allowing the "pop %0" to use memory:

 1) forces the compiler to add annoying stack canaries when
    CONFIG_STACKPROTECTOR_STRONG=y in many places.

 2) Almost always is followed by an immediate "move memory,register"

count before completing the failed request. However, that commit
optimized __ublk_fail_req() to call __ublk_complete_rq() directly
without decrementing the request reference count.
The leaked reference count incorrectly allows user copy and zero copy
operations on the completed ublk request. It also triggers the
WARN_ON_ONCE(refcount_read(&io->ref)) warnings in ublk_queue_reinit()
and ublk_deinit_queue().
Commit c5c5eb24ed61 ("ublk: avoid ublk_io_release() called after ublk
char dev is closed") already fixed the issue for ublk devices using
UBLK_F_SUPPORT_ZERO_COPY or UBLK_F_AUTO_BUF_REG. However, the reference
count leak also affects UBLK_F_USER_COPY, the other reference-counted
data copy mode. Fix the condition in ublk_check_and_reset_active_ref()
to include all reference-counted data copy modes. This ensures that any
ublk requests still owned by the ublk server when it exits have their
reference counts reset to 0.

reset on subsequent enumeration after S3/S4 resume.

The enum_devices_done flag was not reset before sending the

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

Siarhei Vishniakou [Tue, 11 Nov 2025 23:45:19 +0000 (15:45 -0800)] 
HID: playstation: Center initial joystick axes to prevent spurious events

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.

The function save_v_state() served two purposes. First, it saved

extension header if there was no fault. The second part is independent

header for that extension. The kernel skips an extension if it does
not exist, or if the saving fails for some reasons. The error code is

Input: apple_z2 - fix reading incorrect reports after exiting sleep

Under certain conditions (more prevalent after a suspend/resume cycle),
the touchscreen controller can send the "boot complete" interrupt before
it actually finished booting. In those cases, attempting to read touch
data resuls in a stream of "not ready" messages being read and
interpreted as a touch report. Check that the response is in fact a
touch report and discard it otherwise.
