Merge tag 'vfs-7.2-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull misc vfs updates from Christian Brauner: "Features: - Reduce pipe->mutex contention by pre-allocating pages outside the lock in anon_pipe_write(). anon_pipe_write() called alloc_page() once per page while holding pipe->mutex. The allocation can sleep doing direct reclaim and runs memcg charging, which extends the critical section and stalls any concurrent reader on the same mutex. Now up to 8 pages are pre-allocated before the mutex is taken, leftovers are recycled into the per-pipe tmp_page[] cache before unlock, and any remainder is released after unlock, keeping the allocator out of the critical section on both sides. On a writers x readers sweep with 64KB writes against a 1 MB pipe throughput improves 6-28% and average write latency drops 5-22%; under memory pressure - when the cost of holding the mutex across reclaim is highest - throughput improves 21-48% and latency drops 17-33%. The microbenchmark is added to selftests. - uaccess/sockptr: fix the ignored_trailing logic in copy_struct_to_user() to behave as documented and the usize check in copy_struct_from_sockptr() for user pointers, and add copy_struct_{from,to}_bounce_buffer() and copy_struct_to_sockptr() helpers for upcoming users (IPPROTO_SMBDIRECT, IPPROTO_QUIC). - bpf: add a sleepable bpf_real_inode() kfunc that resolves the real inode backing a dentry via d_real_inode(). On overlayfs the inode attached to the dentry doesn't carry the underlying device information; this is used by the filesystem restriction BPF program that was merged into systemd. - docs: add guidelines for submitting new filesystems, motivated by the maintenance burden abandoned and untestable filesystems impose on VFS developers, blocking infrastructure work like folio conversions and iomap migration. Fixes: - libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo() and drop the now-redundant assignments in callers. This began as a one-line dma-buf fix for a path_noexec() warning; a pseudo filesystem has no reason not to set SB_I_NOEXEC. All init_pseudo() callers were audited: the only visible effect is on dma-buf where SB_I_NOEXEC silences the warning. - Handle set_blocksize() failures in legacy filesystems (bfs, hpfs, qnx4, jfs, befs, affs, isofs, minix, ntfs3, omfs). Mounting a device with a sector size > PAGE_SIZE crashed roughly half of them; the rest had the same missing error handling pattern. Plus a follow-up releasing the superblock buffer_head when setting the minix v3 block size fails. - mount: honour SB_NOUSER in the new mount API. - fs/fcntl: fix a SOFTIRQ-unsafe lock order in fasync signaling by switching the process-group paths of send_sigio() and send_sigurg() from read_lock(&tasklist_lock) to RCU, matching the single-PID path. - vfs: add an FS_USERNS_DELEGATABLE flag and set it for NFS, fixing delegated NFS mounts (fsopen() in a container with the mount performed by a privileged daemon) that broke when non-init s_user_ns was tied to FS_USERNS_MOUNT. - selftests/namespaces: fix a hang in nsid_test where an unreaped grandchild kept the TAP pipe write-end open, a waitpid(-1) race in listns_efault_test, and a false FAIL on kernels without listns() where the tests should SKIP. - filelock: fix the break_lease() stub signature for CONFIG_FILE_LOCKING=n. - init/initramfs_test: wait for the async initramfs unpacking before running; the test and do_populate_rootfs() share the parser state. - fs/coredump: reduce redundant log noise in validate_coredump_safety(). - iomap: pass the correct length to fserror_report_io() in __iomap_write_begin(). - backing-file: fix the backing_file_open() kerneldoc. Cleanups: - initramfs: refactor the cpio hex header parsing to use hex2bin() instead of the hand-rolled simple_strntoul() which is reverted, and extend the initramfs KUnit tests to cover header fields with 0x prefixes. - Replace __get_free_pages() and friends with kmalloc()/kzalloc() across quota, proc, ocfs2/dlm, nilfs2, nfs, nfsd, libfs, jfs, jbd2, isofs, fuse, select, namespace, configfs, binfmt_misc, bfs, and the do_mounts init code - part of the larger work of replacing page allocator calls with kmalloc(). - Use clear_and_wake_up_bit() in unlock_buffer() and journal_end_buffer_io_sync() instead of open-coding the sequence. - Drop unused VFS exports: unexport drop_super_exclusive(), remove start_removing_user_path_at(), and fold __start_removing_path() into start_removing_path(). - fs/read_write: narrow the __kernel_write() export with EXPORT_SYMBOL_FOR_MODULES(). - vfs: uapi: retire octal and hex constants in favor of (1 << n) for the O_ flags. Finding a free bit for a new flag across the architectures was needlessly hard with the mixed bases. - dcache: add extra sanity checks of dead dentries in dentry_free() via a new DENTRY_WARN_ONCE() that also prints d_flags. - iov_iter: use kmemdup_array() in dup_iter() to harden the allocation against multiplication overflow. - fs/pipe: write to ->poll_usage only once. - vfs: remove an always-taken if-branch in find_next_fd(). - dcache: use kmalloc_flex() for struct external_name in __d_alloc(). - namei: use QSTR() instead of QSTR_INIT() in path_pts(). - sync_file_range: delete dead S_ISLNK code. - Comment fixes: retire a stale comment in fget_task_next() and fix assorted spelling mistakes"* tag 'vfs-7.2-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (73 commits) backing-file: fix backing_file_open() kerneldoc parameter iomap: pass the correct len to fserror_report_io in __iomap_write_begin vfs: add FS_USERNS_DELEGATABLE flag and set it for NFS filelock: fix break_lease() stub signature for CONFIG_FILE_LOCKING=n vfs: uapi: retire octal and hex numbers in favor of (1 << n) for O_ flags bpf: add bpf_real_inode() kfunc fs/read_write: Do not export __kernel_write() to the entire world libfs: drop redundant SB_I_NOEXEC/SB_I_NODEV in init_pseudo() callers libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo() mount: honour SB_NOUSER in the new mount API fs/fcntl: fix SOFTIRQ-unsafe lock order in fasync signaling selftests/pipe: add pipe_bench microbenchmark fs/pipe: pre-allocate pages outside pipe->mutex in anon_pipe_write fs: retire stale comment in fget_task_next() fs: fix spelling mistakes in comment bfs: replace get_zeroed_page() with kzalloc() binfmt_misc: replace __get_free_page() with kmalloc() configfs: replace __get_free_pages() with kzalloc() fs/namespace: use __getname() to allocate mntpath buffer fs/select: replace __get_free_page() with kmalloc() ...

Sun, 24 May 2026 16:44:59 +0200

selftests/pipe: add pipe_bench microbenchmarkAdd a small selftest that stresses pipe->mutex contention by spawning Nwriter threads that hammer a single pipe with multi-page writes, plus Mreader threads that drain. Each writer records its own write() latencysamples into a log2-bucketed histogram; main aggregates and printstotal writes, throughput, average and percentile (p50/p99) latencies,and the maximum observed latency.Pass --memory-pressure to fork stress-ng (--vm 4 --vm-bytes 80%--vm-method all) for the duration of the run, so alloc_page() inanon_pipe_write() routinely hits direct reclaim. The flag failsfast if stress-ng is not on $PATH.Program print something like the following, for different writes,readers, msgsizes and memory pressure: config: writers=X readers=Y msgsize=Z duration=3 pipe_size=1048576 memory_pressure=[no|yes] writes: total=54451 rate=18150/s throughput_MBps: 1134.40 lat_avg_ns: 275355 lat_p50_ns_upper: 262143 lat_p99_ns_upper: 1048575 lat_max_ns: 2145633Reviewed-by: Jeff Layton Signed-off-by: Breno Leitao Link: https://patch.msgid.link/20260524-fix_pipe-v3-2-bb4a75d23a90@debian.orgSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/Makefile

cad6f32665cbff8e556a1da035e55261f7374ebd - selftests: Deescalate error reporting

Thu, 16 Apr 2026 15:19:24 +0200

selftests: Deescalate error reportingCommit 7e47389142b8 ("selftests: Preserve subtarget failures inall/install") updated the propagation of errors from indivdual kselftesttargets to be similar to that seen with FORCE_TARGETS. While it wouldbe really nice to be in a position to do this currently it is prematureto do this as the default behaviour.At present we default to trying to build all selftests but a combinationof code quality issues and build dependencies mean that it is almostcertain that at least one of them will fail to build (for example,several depend on clang so don't work in a GCC container) and a toplevel failure in the kselftest build reported. Further, the resultingfailures mean that the install target does not run at all so any buildproblem is escallated to a complete failure to produce a kselftesttarball so CI systems that run into issues loose all selftests coverage.This has been causing disruption to a range of CI systems includingKernelCI, mine and Arm's internal one.Revert the commit, users who need this behaviour should be able to useFORCE_TARGETS for the time being. At present users that do this (suchas linux-next) are most likely building a subset of targets known tosucceed in their environments.Link: https://lore.kernel.org/r/20260416-selftests-deescalate-error-reporting-v1-1-38e7c0536227@kernel.orgFixes: 7e47389142b8 ("selftests: Preserve subtarget failures in all/install")Signed-off-by: Mark Brown Signed-off-by: Shuah Khan List of files: /linux/tools/testing/selftests/Makefile

Wed, 15 Apr 2026 04:59:25 +0200

Merge tag 'vfs-7.1-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull vfs mount updates from Christian Brauner: - Add FSMOUNT_NAMESPACE flag to fsmount() that creates a new mount namespace with the newly created filesystem attached to a copy of the real rootfs. This returns a namespace file descriptor instead of an O_PATH mount fd, similar to how OPEN_TREE_NAMESPACE works for open_tree(). This allows creating a new filesystem and immediately placing it in a new mount namespace in a single operation, which is useful for container runtimes and other namespace-based isolation mechanisms. This accompanies OPEN_TREE_NAMESPACE and avoids a needless detour via OPEN_TREE_NAMESPACE to get the same effect. Will be especially useful when you mount an actual filesystem to be used as the container rootfs. - Currently, creating a new mount namespace always copies the entire mount tree from the caller's namespace. For containers and sandboxes that intend to build their mount table from scratch this is wasteful: they inherit a potentially large mount tree only to immediately tear it down. This series adds support for creating a mount namespace that contains only a clone of the root mount, with none of the child mounts. Two new flags are introduced: - CLONE_EMPTY_MNTNS (0x400000000) for clone3(), using the 64-bit flag space - UNSHARE_EMPTY_MNTNS (0x00100000) for unshare() Both flags imply CLONE_NEWNS. The resulting namespace contains a single nullfs root mount with an immutable empty directory. The intended workflow is to then mount a real filesystem (e.g., tmpfs) over the root and build the mount table from there. - Allow MOVE_MOUNT_BENEATH to target the caller's rootfs, allowing to switch out the rootfs without pivot_root(2). The traditional approach to switching the rootfs involves pivot_root(2) or a chroot_fs_refs()-based mechanism that atomically updates fs->root for all tasks sharing the same fs_struct. This has consequences for fork(), unshare(CLONE_FS), and setns(). This series instead decomposes root-switching into individually atomic, locally-scoped steps: fd_tree = open_tree(-EBADF, "/newroot", OPEN_TREE_CLONE | OPEN_TREE_CLOEXEC); fchdir(fd_tree); move_mount(fd_tree, "", AT_FDCWD, "/", MOVE_MOUNT_BENEATH | MOVE_MOUNT_F_EMPTY_PATH); chroot("."); umount2(".", MNT_DETACH); Since each step only modifies the caller's own state, the fork/unshare/setns races are eliminated by design. A key step to making this possible is to remove the locked mount restriction. Originally MOVE_MOUNT_BENEATH doesn't support mounting beneath a mount that is locked. The locked mount protects the underlying mount from being revealed. This is a core mechanism of unshare(CLONE_NEWUSER | CLONE_NEWNS). The mounts in the new mount namespace become locked. That effectively makes the new mount table useless as the caller cannot ever get rid of any of the mounts no matter how useless they are. We can lift this restriction though. We simply transfer the locked property from the top mount to the mount beneath. This works because what we care about is to protect the underlying mount aka the parent. The mount mounted between the parent and the top mount takes over the job of protecting the parent mount from the top mount mount. This leaves us free to remove the locked property from the top mount which can consequently be unmounted: unshare(CLONE_NEWUSER | CLONE_NEWNS) and we inherit a clone of procfs on /proc then currently we cannot unmount it as: umount -l /proc will fail with EINVAL because the procfs mount is locked. After this series we can now do: mount --beneath -t tmpfs tmpfs /proc umount -l /proc after which a tmpfs mount has been placed beneath the procfs mount. The tmpfs mount has become locked and the procfs mount has become unlocked. This means you can safely modify an inherited mount table after unprivileged namespace creation. Afterwards we simply make it possible to move a mount beneath the rootfs allowing to upgrade the rootfs. Removing the locked restriction makes this very useful for containers created with unshare(CLONE_NEWUSER | CLONE_NEWNS) to reshuffle an inherited mount table safely and MOVE_MOUNT_BENEATH makes it possible to switch out the rootfs instead of using the costly pivot_root(2).* tag 'vfs-7.1-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests/namespaces: remove unused utils.h include from listns_efault_test selftests/fsmount_ns: add missing TARGETS and fix cap test selftests/empty_mntns: fix wrong CLONE_EMPTY_MNTNS hex value in comment selftests/empty_mntns: fix statmount_alloc() signature mismatch selftests/statmount: remove duplicate wait_for_pid() mount: always duplicate mount selftests/filesystems: add MOVE_MOUNT_BENEATH rootfs tests move_mount: allow MOVE_MOUNT_BENEATH on the rootfs move_mount: transfer MNT_LOCKED selftests/filesystems: add clone3 tests for empty mount namespaces selftests/filesystems: add tests for empty mount namespaces namespace: allow creating empty mount namespaces selftests: add FSMOUNT_NAMESPACE tests selftests/statmount: add statmount_alloc() helper tools: update mount.h header mount: add FSMOUNT_NAMESPACE mount: simplify __do_loopback() mount: start iterating from start of rbtree List of files: /linux/tools/testing/selftests/Makefile

Forexample, with `TARGETS=net`, the implicit `net/lib` dependency runs after`net`, so a failed `net` build can be followed by a successful `net/lib`build and reset the final result to success.Set `ret` to 1 on any non-zero sub-make exit code and keep it sticky, sothe top-level make returns failure when any selected selftest targetfails.Signed-off-by: Ricardo B.

80bab43f6f235664fff2d3518b3901ba9c4ac5a3 - selftests/liveupdate: add userspace API selftests

Tue, 25 Nov 2025 17:58:46 +0100

selftests/liveupdate: add userspace API selftestsIntroduce a selftest suite for LUO. These tests validate the coreuserspace-facing API provided by the /dev/liveupdate device and itsassociated ioctls.The suite covers fundamental device behavior, session management, and thefile preservation mechanism using memfd as a test case. This providesregression testing for the LUO uAPI.The following functionality is verified:Device Access: Basic open and close operations on /dev/liveupdate. Enforcement of exclusive device access (verifying EBUSY on a second open).Session Management: Successful creation of sessions with unique names. Failure to create sessions with duplicate names.File Preservation: Preserving a single memfd and verifying its content remains intact post-preservation. Preserving multiple memfds within a single session, each with unique data. A complex scenario involving multiple sessions, each containing a mix of empty and data-filled memfds.Note: This test suite is limited to verifying the pre-kexec functionalityof LUO (e.g., session creation, file preservation). The post-kexecrestoration of resources is not covered, as the kselftest framework doesnot currently support orchestrating a reboot and continuing execution inthe new kernel.Link: https://lkml.kernel.org/r/20251125165850.3389713-17-pasha.tatashin@soleen.comSigned-off-by: Pasha Tatashin Reviewed-by: Pratyush Yadav Reviewed-by: Mike Rapoport (Microsoft) Tested-by: David Matlack Cc: Aleksander Lobakin Cc: Alexander Graf Cc: Alice Ryhl Cc: Andriy Shevchenko Cc: anish kumar Cc: Anna Schumaker Cc: Bartosz Golaszewski Cc: Bjorn Helgaas Cc: Borislav Betkov Cc: Chanwoo Choi Cc: Chen Ridong Cc: Chris Li Cc: Christian Brauner Cc: Daniel Wagner Cc: Danilo Krummrich Cc: Dan Williams Cc: David Hildenbrand Cc: David Jeffery Cc: David Rientjes Cc: Greg Kroah-Hartman Cc: Guixin Liu Cc: "H.
