Most of the issues addressed are found by sashiko and other AI agents. It all started with me missing the report by Sashiko in [1]. Each round of fix expanded the AI scope of review and unearthed more issues.

The notification fixes make per-CPU notification work truly per-CPU, avoid running per-vCPU notification handling from IPI context, keep RX buffer release serialized under rx_lock, validate framework notification payload layout before copying from the shared RX buffer, and avoid dereferencing notifier entries after they may have been unregistered. The remaining fixes reject FF-A drivers without an ID table at registration time, avoid freeing an unallocated RX buffer after allocation failure, unregister the FF-A v1.0 bus notifier on teardown, bound register-based PARTITION_INFO_GET descriptor copies, align the stored RxTx buffer size with the size mapped to firmware, and fix sched-recv callback partition lookup on the circular partition list. ---------------------------------------------------------------- Sudeep Holla (11): firmware: arm_ffa: Check for NULL FF-A ID table while driver registration firmware: arm_ffa: Skip free_pages on RX buffer alloc failure firmware: arm_ffa: Avoid collapsing NPI work from different CPUs firmware: arm_ffa: Fix per-vcpu self notifications handling in workqueue firmware: arm_ffa: Unregister bus notifier on teardown for FF-A v1.0 firmware: arm_ffa: Bound PARTITION_INFO_GET_REGS copies firmware: arm_ffa: Keep framework RX release under lock firmware: arm_ffa: Validate framework notification message layout firmware: arm_ffa: Align RxTx buffer size before mapping firmware: arm_ffa: Snapshot notifier callbacks under lock firmware: arm_ffa: Fix sched-recv callback partition lookup drivers/firmware/arm_ffa/bus.c | 4 +- drivers/firmware/arm_ffa/driver.c | 144 ++++++++++++++++++++++++++------------ 2 files changed, 104 insertions(+), 44 deletions(-)
