Hi ARM SoC Team, Please pull ! Regards, Sudeep -->8 The following changes since commit 1b929c02afd37871d5afb9d498426f83432e71c2: Linux 6.2-rc1 (2022-12-25 13:41:39 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-fixes-6.2 for you to fetch changes up to e325285de2cd82fbdcc4df8898e4c6a597674816: firmware: arm_scmi: Fix virtio channels cleanup on shutdown (2023-01-03 16:50:44 +0000) ---------------------------------------------------------------- Arm SCMI fixes for v6.2 Few fixes addressing: 1. Possible compromise with the shorter message size from a misbheaving SCMI platform firmware. The shmem accesses are now hardened to handle the same in fetch_notification and fetch_response. 2. Possible unsafe locking scenario which is solved by calling virtio_break_device() before getting hold of vioch->lock. 3. Possible stale error status reported from a previous message being used again as it is not cleared. ---------------------------------------------------------------- Cristian Marussi (4): firmware: arm_scmi: Clear stale xfer->hdr.status firmware: arm_scmi: Harden shared memory access in fetch_response firmware: arm_scmi: Harden shared memory access in fetch_notification firmware: arm_scmi: Fix virtio channels cleanup on shutdown drivers/firmware/arm_scmi/driver.c | 2 ++ drivers/firmware/arm_scmi/shmem.c | 9 ++++++--- drivers/firmware/arm_scmi/virtio.c | 7 ++++++- 3 files changed, 14 insertions(+), 4 deletions(-)
