[PATCH openEuler-1.0-LTS] mm: shmem: don't truncate page if memory failure happens
by Tong Tiangen 27 Dec '24

27 Dec '24

From: Yang Shi <shy828301(a)gmail.com> stable inclusion from stable-v5.15.80 commit 94fa250ea55cd4eea8049011ea4045343547ebd8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBE6C6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a7605426666196c5a460dd3de6f8dac1d3c21f00 upstream. The current behavior of memory failure is to truncate the page cache regardless of dirty or clean. If the page is dirty the later access will get the obsolete data from disk without any notification to the users. This may cause silent data loss. It is even worse for shmem since shmem is in-memory filesystem, truncating page cache means discarding data blocks. The later read would return all zero. The right approach is to keep the corrupted page in page cache, any later access would return error for syscalls or SIGBUS for page fault, until the file is truncated, hole punched or removed. The regular storage backed filesystems would be more complicated so this patch is focused on shmem. This also unblock the support for soft offlining shmem THP.
