/* Summary */
This contains fixes for the current development cycle:
- libfs: Make readdir on tmpfs walk the offset tree in offset order
instead of d_children to avoid skipping entries or relisting the whole
directory.
It's faster too. Listing a million entries takes 114ms instead of
146ms, and 113ms instead of 470ms with four processes listing in
parallel.
- iomap: Finish the ->iomap_next() conversion that started in v7.3.
The nilfs2 and fuse ext_map iomap code added this merge window is
converted so now we can remove the ->iomap_begin()/->iomap_end()
fallback. We waited until the new iomap users from other trees were in
mainline otherwise this would have been very messy.
- errseq: Retry with the current value when the cmpxchg() in
errseq_check_and_advance() fails to avoid an old value coming back
later hiding the errors.
- aio: Hold an extra count for exit_aio() itself so it can't return
before the last free_ioctx_reqs() callback has called complete().
- pidfd: Fail the namespace ioctls with EREMOTE unless the target is
visible in the caller's pid namespace like PIDFD_GET_INFO does.
- eventpoll: Wake the next waiter when a woken waiter returns early
because of a fatal signal to avoid sleeping forever.
- backing-file: Pass RWF_NOAPPEND on to synchronous writes to the
backing file.
- initrd: Flush the deferred fput() of the ramdisk file before mounting
root.
- iov_iter: Take an unsigned long segment count in import_iovec(). The
upper 32 bits of the count passed to readv(), writev() and friends
were dropped before the UIO_MAXIOV check.
- splice: Advance the pipe tail before checking for a full bvec array
in splice_to_socket(). The last buffer was counted again, so MSG_MORE
was set although the pipe was empty and small TCP transfers waited
for the cork timeout.
- vfs:
* Reject negative offsets for SEEK_DATA and SEEK_HOLE in
default_llseek() and use must_set_pos() for its whence handling.
* Only clear tv_nsec in timestamp_truncate() when clamping changed
the seconds. Timestamps whose seconds were exactly at a filesystem
time limit lost their subsecond part.
* Don't leak the kernel-internal STATX_ATTR_CHANGE_MONOTONIC in
stx_attributes_mask.
* Clamp the FIONREAD result to the int range so a file with 4 GiB
left isn't reported as empty.
* Fix the SEEK_CUR f_lock check.
- selftests: Fix the statmount and mount_setattr tests on 32-bit and
s390, build the fchmodat2 and openat2 tests without sanitizers when
the toolchain lacks the runtimes and fix a clang warning in the
mount-notify test.
- docs: Fix a docutils warning in porting.rst.

Hey Linus,
As is the new normal, this is larger set of fixes for this cycle. I have
a bunch of fixes in the pipeline but no need to delay the current set
any longer than necessary.
/* Summary */
- writeback:
* Update dirtied_when instead of dirtied_time_when when a wb switch
puts an inode at the newest end of the target b_dirty list. The list
was left out of order so move_expired_inodes() could stop before
older inodes, and the lazytime expiration timestamp was reset.
* Clear the old wb's dirty-I/O state and bandwidth contribution when a
batch of inode switches leaves its dirty lists empty. An empty wb
stayed scheduled for periodic writeback and inflated
bdi->tot_write_bandwidth.
* Take wb_switch_rwsem across the inode scan of
cleanup_offline_cgwb(). The v7.3-rc5 fix that rotates scanned inodes
let a scan racing a sync()'s queue_io() move lazytime inodes past
the sync's cutoff, so sync() returned without persisting their
timestamps.
* Don't kick writeback for an IOCB_DONTCACHE write on an inode that
has no wb yet. With cgroup writeback an O_DIRECT RWF_DONTCACHE write
to a block device dereferenced NULL.
- statmount/listmount/listns:
* Refuse statmount() string requests with a buffer that isn't larger
than struct statmount.
* Don't wrap around with a U64_MAX cursor in listmount() and listns().
* Don't end listns() at an inactive namespace.
* Only add init_ipc_ns and init_net to the namespace trees if
CONFIG_IPC_NS and CONFIG_NET_NS are enabled.
- iomap:
* Only mark blocks uptodate in __iomap_write_begin() after reading
them and let __iomap_write_end() mark the zeroed blocks uptodate
once the copy from userspace succeeded.
* Check a chunk against max_integrity_io_size() on its own before the
bio size check.
* Only enforce block alignment for direct I/O into holes and
unwritten extents if IOMAP_DIO_FSBLOCK_ALIGNED is set.
- backing-file:
* Check S_APPEND and S_IMMUTABLE on the backing inode. FUSE
passthrough opens the backing file with vfs_open() which skips
may_open(), so anyone who may open the FUSE file for writing could
overwrite an append-only backing file anywhere or write to an
immutable one. Open, mmap and writes now check the backing inode
the way may_open() and do_mmap() do.
* Always call kiocb_end_write() for a queued write
* Let backing files inherit FMODE_NONOTIFY from the user file. The
event fds fanotify creates for permission events on a stacked
filesystem raised FS_OPEN_PERM on the real path from inside the
listener's read() and deadlocked listeners with marks on both
layers.
- pidfs:
* Look the task up before checking for exit information in
PIDFD_GET_INFO and start over if the task no longer owns the pid
once all fields have been read. A caller racing release_task() got
neither PIDFD_INFO_PID nor PIDFD_INFO_EXIT or ESRCH although the
exit information was available, and a caller racing a sub-thread's
exec reported that thread's tid as the pid.
* Clear the mask bits of fields that lie beyond the struct size the
caller passed. The uapi header promises that the mask names no such
field but a caller passing PIDFD_INFO_SIZE_VER0 got the coredump and
supported mask bits set for fields that were never written.
- aio:
* Give the aio ring a ->read_folio that fails with EIO so a fault on a
ring whose file was truncated gets SIGBUS instead of jumping to
NULL.
* Check nr_events against the ring size before doubling it in
ioctx_alloc().
- splice:
* Only write back an implicit file position in do_splice() when the
splice helper succeeded. splice doesn't take f_pos_lock so a failed
splice restored a stale snapshot over a position that a concurrent
getdents() had moved. On ext2 the next readdir then trusted an
offset inside a directory entry.
* Retry tee() when the input pipe was emptied or the output pipe
filled between the prep steps and link_pipe() instead of returning 0
while the input pipe still has writers, as splice_pipe_to_pipe()
does.
- ucount:
* Take the reference that pins a ucounts level on the 0 -> 1
transition before checking the rlimit.
* Read the parent ucounts before dropping the rlimit count in
do_dec_rlimit_put_ucounts().
- inode:
* Rotate inodes whose page cache couldn't be dropped to the tail of
the LRU.
* Skip inodes that another LRU walker is isolating.
- setns:
* Set nsset->flags before anything in prepare_nsset() can fail so the
error path drops the cred prepared for CLONE_NEWUSER. A failing
setns() with CLONE_NEWUSER and CLONE_NEWNS leaked it together with
its user namespace.
* Refuse setns(CLONE_NEWNS) for a task that shares its fs_struct again
when more namespaces are requested.
- minix:
* Restore uptodate on the pinned bitmap buffers before redirtying them
after a failed writeback instead of tripping the warning in
mark_buffer_dirty(), as ext2 and ext4 do for their superblock
buffers.
* Reject rmdir() of a directory with a corrupted link count with
EFSCORRUPTED instead of hitting the drop_nlink() warning.
- userns: Keep the exec securebits and their locks when creating or
joining a user namespace. set_cred_user_ns() reset all securebits to
SECUREBITS_DEFAULT so anyone who may create a user namespace could
shed SECBIT_EXEC_RESTRICT_FILE and SECBIT_EXEC_DENY_INTERACTIVE with a
single unshare(CLONE_NEWUSER).
- fs: Honor FOP_UNSIGNED_OFFSET in sys_llseek() and in the pread64(),
pwrite64(), preadv() and pwritev() wrappers.
- proc/kcore: Advance the vmalloc retry in read_kcore_iter() by the
last vread_iter() copy instead of the running total.
- eventpoll: Return the error when the wakeup source for EPOLLWAKEUP
can't be created in EPOLL_CTL_MOD instead of reporting success
without suspend protection.
- coredump: Mark do_coredump() noinline_for_stack.
- nsfs: Check the trailing bytes of a namespace file handle in bytes
instead of words.
- netfs: Restore the per-level and per-point decoding of the debug
mask.
- exportfs: Release the directory file get_name() opened with
__fput_sync(). From nfsd's kernel threads the deferred fputs arrived
faster than delayed_fput retired them and each pinned the directory's
readdir state, growing unreclaimable slab by about 90 MB per second
under a parallel tree walk.
- fs: Call ramfs_kill_sb() for a ramfs rootfs. Since rootfs can be
unmounted as of v7.0 its struct ramfs_fs_info was leaked.
- signal: Check the blocked mask for every entry
dequeue_synchronous_signal() looks at. The scan could select a blocked
synchronous signal and deliver it while blocked.
- super: Convert the superblock device table from an rhltable to a
plain hashtable under a spinlock. This fixes a bug from v7.3 where
fs_bdev_freeze() froze a btrfs filesystem through a stale member that
open_ctree() had already released while the freeze was waiting for SB_BORN.
- fork: Leave rcu_users at zero until copy_process() can't fail anymore.
bpf_task_acquire() handed out trusted references to the new task from
the task_alloc LSM hook and sched_ext's ops.init_task() and a failing
fork freed the task behind them.
- xattr: Always run cap_convert_nscap() for a security.capability write.
A zero-length setxattr() skipped it and let an unprivileged caller
without CAP_SETFCAP or write permission on the file plant an empty
security.capability xattr that made every execve() of the binary fail
with EINVAL.
- namei: Skip the S_ISDIR assertion in
- proc: Refuse to mount on entries below /proc/<pid>/net like fd/,
fdinfo/ and map_files/. proc_net_d_revalidate() always fails so the
first lookup by anyone with search permission ran d_invalidate() on
the dentry and detached every mount on it, locked mounts included.
- libfs: Hold one mount reference for all pins instead of one per pin.
The pin count is what keeps the mount alive, so the per-pin reference
only cost a mntget() and a mntput() through
mntput_no_expire_slowpath() for every debugfs, tracefs, securityfs or
configfs file that comes and goes.
- iov_iter: Return 0 from iov_iter_alignment() for an empty iterator of
any type.
- watch_queue: Give info_id its own storage instead of overlaying it
with rcu_head.
- filelock: Take an active superblock reference while waiting for a
delegation break. After a lazy umount closing the delegation holder
could shut down the superblock under the waiter whose final iput()
then ran shmem_evict_inode() on freed state.
- fs: Skip the copy_file_range() write limit checks when there is no
data to copy.
- bpf: Allow bpf_d_path() from fentry on filp_close_sync(). Since
close_range() became synchronous this cycle close(), close_range()
and the closes on exec and exit no longer go through filp_close().
fexit stays rejected since the file may be gone by then.
- fs_pin: Dequeue the wait entry unconditionally in pin_kill(). A
spuriously woken waiter kept its on-stack entry queued, took that as
proof that the pin was alive and used the freed acct structure when
umount() of the accounting file raced acct(2).
- dcache: Don't fail __d_obtain_alias() for an inode without links and
aliases. The ESTALE check added this cycle broke open_by_handle_at()
and nfsd file handle decoding on NFS and FUSE where i_nlink is just
what the server last reported and the handle may well still be valid.
- selftests/ovl: Fix the mountinfo expectations of the detached layer
test which has failed since it was added.
