Fri, 05 Dec 2025 05:46:20 +0000

dm pcache: fix segment info indexingSegment info indexing also used sizeof(struct) instead of the4K metadata stride, so info_index could point between slots andsubsequent writes would advance incorrectly. Derive info_indexfrom the pointer returned by the segment meta search usingPCACHE_SEG_INFO_SIZE and advance to the next slot for futureupdates.Signed-off-by: Li Chen Signed-off-by: Dongsheng Yang Signed-off-by: Mikulas Patocka Reviewed-by: Zheng Gu Cc: stable@vger.kernel.org # 6.18 List of files: /linux/drivers/md/dm-pcache/cache_segment.c

ebbb90344a7da2421e4b54668b94e81828b8b308 - dm-pcache: advance slot index before writing slot

Fri, 05 Dec 2025 05:46:18 +0000

dm-pcache: advance slot index before writing slotIn dm-pcache, in order to ensure crash-consistency, a dual-copy schemeis used to alternately update metadata, and there is a slot index thatrecords the current slot. However, in the write path the currentimplementation writes directly to the current slot indexed by slotindex, and then advances the slot — which ends up overwriting theexisting slot, violating the crash-consistency guarantee.This patch fixes that behavior, preventing metadata from beingoverwritten incorrectly.In addition, this patch add a missing pmem_wmb() after memcpy_flushcache().Signed-off-by: Dongsheng Yang Signed-off-by: Mikulas Patocka Reviewed-by: Zheng Gu Cc: stable@vger.kernel.org # 6.18 List of files: /linux/drivers/md/dm-pcache/cache_segment.c
