Pull vfs fixes from Christian Brauner: - Fix fsnotify FMODE_NONOTIFY* handling. This also disables fsnotify on all pseudo files by default apart from very select exceptions. This carries a regression risk so we need to watch out and adapt accordingly. However, it is overall a significant improvement over the current status quo where every rando file can get fsnotify enabled. - Cleanup and simplify lockref_init() after recent lockref changes. - Fix vboxfs build with gcc-15. - Add an assert into inode_set_cached_link() to catch corrupt links. - Allow users to also use an empty string check to detect whether a given mount option string was empty or not. - Fix how security options were appended to statmount()'s ->mnt_opt field. - Fix statmount() selftests to always check the returned mask. - Fix uninitialized value in vfs_statx_path(). - Fix pidfs_ioctl() sanity checks to guard against ioctl() overloading and preserve extensibility. * tag 'vfs-6.14-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: vfs: sanity check the length passed to inode_set_cached_link() pidfs: improve ioctl handling fsnotify: disable pre-content and permission events by default selftests: always check mask returned by statmount(2) fsnotify: disable notification by default for all pseudo files fs: fix adding security options to statmount.mnt_opt fsnotify: use accessor to set FMODE_NONOTIFY_* lockref: remove count argument of lockref_init gfs2: switch to lockref_init(..., 1) gfs2: use lockref_init for gl_lockref statmount: let unset strings be empty vboxsf: fix building with GCC 15 fs/stat.c: avoid harmless garbage value problem in vfs_statx_path()

selftests: always check mask returned by statmount(2)

2025-02-07T09:27:26Z

STATMOUNT_MNT_OPTS can actually be missing if there are no options. This is a change of behavior since 75ead69a7173 ("fs: don't let statmount return empty strings"). The other checks shouldn't actually trigger, but add them for correctness and for easier debugging if the test fails.

selftests/seccomp: validate uretprobe syscall passes through seccomp

2025-02-06T21:19:14Z

The uretprobe syscall is implemented as a performance enhancement on x86_64 by having the kernel inject a call to it on function exit; User programs cannot call this system call explicitly. As such, this syscall is considered a kernel implementation detail and should not be filtered by seccomp. Enhance the seccomp bpf test suite to check that uretprobes can be attached to processes without the killing the process regardless of seccomp policy.

selftests: mptcp: connect: -f: no reconnect

2025-02-06T01:54:32Z

The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored. The recent modification only shown an existing issue: xdisconnect() doesn't need to be used here, only the shutdown() part is needed.
