Total patches: 134 Fixes: tags: 86 cc:stable patches: 52 Reviews/patch: 0.73 Reviewed rate: 59% Summary of patch series in this merge: - "ocfs2: exit recovery thread on mount error path" (Joseph Qi): Stop OCFS2 recovery before freeing failed-mount state and replay slots, closing use-after-free and double-free races. Defer suballocator reclaim to break a transaction-lock deadlock with dismount. - "ocfs2: validate suballoc slot and bit of metadata blocks" (Joseph Qi): Validate OCFS2 metadata suballocator slots, bits and directory index block locations. Reject corrupt metadata with filesystem errors instead of BUGs or out-of-bounds accesses. - "ocfs2: deal with legacy signed name hash values" (Joseph Qi): Restore OCFS2 lookups for non-ASCII names stored with legacy signed hashes. Use stored xattr hashes during bucket splits to avoid duplicate entries and spurious ENOSPC failures. - "ocfs2: stabilize dentry names in file and setattr traces" (Cen Zhang): Snapshot OCFS2 names during file and setattr tracing to prevent rename races using freed storage or mismatched names and lengths. Preserve trace formats and the locked release open-count sample. - "panic: fix panic_force_cpu= redirect races and NMI bypass" (Bradley Morgan): Fix panic_force_cpu races and NMI redirection so crash-kernel CPU selection is honored. Preserve variable arguments on failed redirects and use a static message buffer. - "fat: allocate multiple clusters in fallocate" (Matheus Alves de Almeida): Allocate FAT clusters in batches for FALLOC_FL_KEEP_SIZE and batch FAT updates. This removes repeated single-cluster allocation overhead, particularly on synchronous mounts. - "scripts/gdb: fix radix tree lookup and stack depot diagnostic" (Ting-Han Hou): Fix GDB radix-tree lookup and its handling of XArray sibling, retry and zero entries. Also repair the stack-depot diagnostic for an out-of-range pool index. - "hung_task: Improve warning budget handling and task reporting" (Aaron Tomlin): Reset the hung-task warning budget after recovery so later hangs remain visible. Keep the configured limit intact and emit one summary per scan when detailed reports exhaust the budget. - "bootconfig: Reject unexpected data after null character and cleanups" (Masami Hiramatsu (Google)): Reject bootconfig data after an embedded null while accepting trailing padding. Validate the full input in the userspace tool, and retain internal tree sanity checks there rather than in the kernel. - "kbuild: GCOV cleanups following the prefer-atomic fix" (Konstantin Khorenko): Use the actual GCOV build flags in the prefer-atomic compiler probe. Move flag setup into scripts/Makefile.gcov and skip the probe when GCOV is disabled. - "ocfs2: xattr bucket validation fixes" (Joseph Qi): Accept valid OCFS2 xattr buckets spanning 512-byte blocks, avoiding false read-only remounts. Reject misaligned buckets and return errors instead of panicking on corrupt defrag metadata. - "ocfs2: fix metadata reservation for xattr value trees" (Joseph Qi): Reserve enough OCFS2 metadata for new and relocated xattr value trees. Fix shortfalls which could cause ENOSPC, dropped entries and leaked clusters on fragmented filesystems; remove duplicate reservations. - "Introduce arch_do_panic" (Mete Durlu): Add arch_do_panic() and move s390 and sparc handling out of generic panic code. The architecture-specific actions now follow the end-of-panic marker. - "checkpatch: userspace improvements" (Petr Vorel): Improve checkpatch's userspace detection and suppress kernel-only checks. Recognize standard inttypes macros and add explicit --userspace and --no-userspace overrides. - "ocfs2: validate dr_fs_generation of dir index root blocks" (Joseph Qi): Check OCFS2 directory index generations and leaf block numbers. Reject stale or misplaced blocks instead of using metadata left by a previously formatted filesystem. - "selftests/membarrier: Skip an unregistered memory barrier test on Musl" (Chris Gellermann): Skip the unregistered membarrier test when libc has already registered the command. Musl does this during thread creation, causing false failures in the multithreaded test. - "init: fix array boundary bugs in boot parameter parsing" (Wilson Felipe Pereira): Fix boot argument boundary cases which leave stale arguments in init's command line or panic when replacing the final environment variable. Clear the last slot and check duplicates before the limit. Summary of the 87 singletons in this merge: The OCFS2 singletons fix deadlocks between xattr updates and inline truncation, and during inode reclaim. Corrupt quota and extent metadata could also crash the kernel or corrupt memory; these paths now check the layout before using it. Other fixes close use-after-free and publication races around cluster reconfiguration, node failure, quota remount errors and shared refcount trees. New files now retain security labels from all stacked LSMs instead of silently dropping all but one. Valid xattr insertions also stop tripping FORTIFY on builds with counted arrays. Elsewhere, a lost wakeup could leave hardware-monitoring reads stuck in unkillable sleep and block further I2C traffic. That is fixed, as are kernel memory leaks in POSIX message-queue notifications and tmpfs casefold setup which could grow until memory is exhausted. A driver removal race which could crash the kernel is fixed too. The hibernation command through reboot() also stops taking the same mutex twice, avoiding a deadlock before suspension. On the boot side, bzip2 decoding now accepts valid full blocks emitted by lbzip2, fixing failures to boot those compressed kernels. Malformed bzip2 streams can no longer overflow the decode buffer, and LZ4 initrds are checked before the decoder can read past their end. FAT rejects geometry which overflows the data-area calculation on 32-bit systems, and rolls back entries when inode setup fails, preventing failed creations from reappearing after remount. The x86 XOR and RAID6 AVX paths also avoid imposing a slowdown on subsequent SSE code. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCat57YgAKCRDdBJ7gKXxA jofGAQDBRlA6AI/WIWAuSb9FH4RIMe16EU3klIYoNqgY3eMbLwD/f8J1rm4gBpBl eXV7nwZMb8Ackw1+2CuBtbvpLfjQUA4= =JLjf -----END PGP SIGNATURE----- Merge tag 'mm-nonmm-stable-2026-10-25-14-57' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull non-MM updates from Andrew Morton: - "ocfs2: exit recovery thread on mount error path" (Joseph Qi): Stop OCFS2 recovery before freeing failed-mount state and replay slots, closing use-after-free and double-free races.
