[PATCH v2] clocksource: clps711x: Fix resource leaks in error paths

by Zhen Ni

The current implementation of clps711x_timer_init() has multiple error paths that directly return without releasing the base I/O memory mapped via of_iomap(). Fix of_iomap leaks in err paths.

[PATCH] RDMA/rxe: Fix race in do_task() when draining

by Gui-Dong Han

When do_task() exhausts its RXE_MAX_ITERATIONS budget, it unconditionally sets the task state to TASK_STATE_IDLE to reschedule. This overwrites the TASK_STATE_DRAINING state that may have been concurrently set by rxe_cleanup_task() or rxe_disable_task(). This race condition breaks the cleanup and disable logic, which expects the task to stop processing new work. The cleanup code may proceed while do_task() reschedules itself, leading to a potential use-after-free. This bug was introduced during the migration from tasklets to workqueues, where the special handling for the draining case was lost. Fix this by restoring the original behavior. If the state is TASK_STATE_DRAINING when iterations are exhausted, continue the loop by setting cont to 1. This allows new iterations to finish the remaining work and reach the switch statement, which properly transitions the state to TASK_STATE_DRAINED and stops the task as intended.

[PATCH] scsi: hptiop: Add check for device-provided context pointer in ITL callback

by Guangshuo Li

An untrusted device may return a NULL context pointer in the request header. hptiop_iop_request_callback_itl() dereferences that pointer unconditionally to write result fields and to invoke arg->done(), which can cause a NULL pointer dereference. Add a NULL check for the reconstructed context pointer. If it is NULL, acknowledge the request by writing the tag to the outbound queue and return early.

Actually the race happens regardless of wait_for_completion_timeout() exit status, e.g. the waiting side may hit a timeout and the concurrent completing side is still able to free the skb. Skbs which are sent by rtw89_core_tx_kick_off_and_wait() are owned by the driver. They don't come from core ieee80211 stack so no need to pass them to ieee80211_tx_status_ni() on completing side. Introduce a work function which will act as a garbage collector for rtw89_tx_wait_info objects and the associated skbs. Thus no potentially heavy locks are required on the completing side.

CMN S3's DTM offset is different between r0px and r1p0, and it turns out this was not a error in the earlier documentation, but does actually exist in the design. Lovely.
