Subject: [PATCH v2 00/10] mpi3mr: Few Enhancements and minor fixes
Date: Thu, 9 Jul 2026 00:02:55 +0530 [thread overview]
Message-ID: <20260708183305.244485-1-ranjan.kumar@broadcom.com> (raw)
Few Enhancements and minor fixes of mpi3mr driver.
Changes since v1:
- Fixed test robot build warning.
- Patch 1: Added le32_to_cpu() conversion for driver_pg1.flags to prevent
incorrect logic on big-endian architectures.
- Patch 4: Added bounds checking for firmware-provided NVMe page size to
prevent undefined shift behavior and potential divide-by-zero panics.
- Patch 5: Added missing dma_rmb() memory barriers in reply queue
processing loops to prevent weakly ordered architectures from
processing stale data.
- Patch 6: Hardened operational queue error handling to prevent
NULL pointer dereferences and deferred kernel panics
during driver cleanup.
- Patch 7: Fixed a TOCTOU Use-After-Free race condition and reference leak
during firmware event cleanup by safely acquiring the event reference
under a spinlock.
- Patch 8: Added missing NULL pointer checks for rphy allocations and
handled sas_rphy_add() failures to prevent NULL pointer dereferences
and resource leaks.
- Patch 9: Added return value check for mpi3mr_add_host_phy() to prevent
a NULL pointer dereference during device addition events.
