[PATCH OLK-6.6] userfaultfd: don't BUG_ON() if khugepaged yanks our page table
by Liu Shixin 10 Oct '24

10 Oct '24

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v6.6.51 commit 4a594acc12d5954cdc71d4450a386748bf3d136a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9P2 CVE: CVE-2024-46838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4828d207dc5161dc7ddf9a4f6dcfd80c7dd7d20a upstream. Since khugepaged was changed to allow retracting page tables in file mappings without holding the mmap lock, these BUG_ON()s are wrong - get rid of them. We could also remove the preceding "if (unlikely(...))" block, but then we could reach pte_offset_map_lock() with transhuge pages not just for file mappings but also for anonymous mappings - which would probably be fine but I think is not necessarily expected.
