2025-03-20libfs: Fix duplicate directory entry in offset_dir_lookupYongjian Sun1-1/+1
There is an issue in the kernel: In tmpfs, when using the "ls" command to list the contents of a directory with a large number of files, glibc performs the getdents call in multiple rounds. If a concurrent unlink occurs between these getdents calls, it may lead to duplicate directory entries in the ls output. One possible reproduction scenario is as follows: Create 1026 files and execute ls and rm concurrently: for i in {1..1026}; do echo "This is file $i" > /tmp/dir/file$i done ls /tmp/dir rm /tmp/dir/file4 ->getdents(file1026-file5) ->unlink(file4) ->getdents(file5,file3,file2,file1) It is expected that the second getdents call to return file3 through file1, but instead it returns an extra file5. The root cause of this problem is in the offset_dir_lookup function. It uses mas_find to determine the starting position for the current getdents call. Since mas_find locates the first position that is greater than or equal to mas->index, when file4 is deleted, it ends up returning file5. It can be fixed by replacing mas_find with mas_find_rev, which finds the first position that is less than or equal to mas->index.

2025-03-19fuse: fix possible deadlock if rings are never initializedLuis Henriques1-1/+1
When mounting a user-space filesystem using io_uring, the initialization of the rings is done separately in the server side. If for some reason (e.g. a server bug) this step is not performed it will be impossible to unmount the filesystem if there are already requests waiting. This issue is easily reproduced with the libfuse passthrough_ll example, if the queue depth is set to '0' and a request is queued before trying to unmount the filesystem. When trying to force the unmount, fuse_abort_conn() will try to wake up all tasks waiting in fc->blocked_waitq, but because the rings were never initialized, fuse_uring_ready() will never return 'true'.

2025-03-19netfs: Fix collection of results during pause when collection offloadedDavid Howells1-8/+10
A netfs read request can run in one of two modes: for synchronous reads writes, the app thread does the collection of results and for asynchronous reads, this is offloaded to a worker thread. This is controlled by the NETFS_RREQ_OFFLOAD_COLLECTION flag. Now, if a subrequest incurs an error, the NETFS_RREQ_PAUSE flag is set to stop the issuing loop temporarily from issuing more subrequests until a retry is successful or the request is abandoned. When the issuing loop sees NETFS_RREQ_PAUSE, it jumps to netfs_wait_for_pause() which will wait for the PAUSE flag to be cleared - and whilst it is waiting, it will call out to the collector as more results acrue... But this is the wrong thing to do if OFFLOAD_COLLECTION is set as we can then end up with both the app thread and the work item collecting results simultaneously. This manifests itself occasionally when running the generic/323 xfstest against multichannel cifs as an oops that's a bit random but frequently involving io_submit() (the test does lots of simultaneous async DIO reads). Fix this by only doing the collection in netfs_wait_for_pause() if the NETFS_RREQ_OFFLOAD_COLLECTION is not set.

2025-03-19fuse: fix uring race condition for null dereference of fcJoanne Koong1-2/+2
There is a race condition leading to a kernel crash from a null dereference when attemping to access fc->lock in fuse_uring_create_queue(). fc may be NULL in the case where another thread is creating the uring in fuse_uring_create() and has set fc->ring but has not yet set ring->fc when fuse_uring_create_queue() reads ring->fc. There is another race condition as well where in fuse_uring_register(), ring->nr_queues may still be 0 and not yet set to the new value when we compare qid against it. This fix sets fc->ring only after ring->fc and ring->nr_queues have been set, which guarantees now that ring->fc is a proper pointer when any queues are created and ring->nr_queues reflects the right number of queues if ring is not NULL. We must use smp_store_release() and smp_load_acquire() semantics to ensure the ordering will remain correct where fc->ring is assigned only after ring->fc and ring->nr_queues have been assigned.

2025-03-18efivarfs: fix NULL dereference on resumeJames Bottomley1-2/+48
LSMs often inspect the path.mnt of files in the security hooks, and this causes a NULL deref in efivarfs_pm_notify() because the path is constructed with a NULL path.mnt. Fix by obtaining from vfs_kern_mount() instead, and being very careful to ensure that deactivate_super() (potentially triggered by a racing userspace umount) is not called directly from the notifier, because it would deadlock when efivarfs_kill_sb() tried to unregister the notifier chain. [ Al notes: Umm... That's probably safe, but not as a long-term solution - it's too intimately dependent upon fs/super.c internals. The reasons why you can't run into ->s_umount deadlock here are non-trivial... ] Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Link: https://lore.kernel.org/r/e54e6a2f-1178-4980-b771-4d9bafc2aa47@tnxip.de Link: https://lore.kernel.org/r/3e998bf87638a442cbc6864cdcd3d8d9e08ce3e3.camel@HansenPartnership.com Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

However, squashfs_cache_delete() only checks for a NULL cache, and attempts to dereference the invalid pointer.

We just had a report of the assert for "btree in write buffer for non-write buffer btree" popping during the 6.14 upgrade. - 150TB filesystem, after a reboot the upgrade was able to continue from where it left off, so no major damage. But with 6.14 about to come out we want to get this tracked down asap, and need more data if other users hit this. Convert the BUG_ON() to an emergency read-only, and print out btree, the key itself, and stack trace from the original write buffer update (which did not have this check before).

2025-03-11vboxsf: Add __nonstring annotations for unterminated stringsKees Cook1-2/+1
When a character array without a terminating NUL character has a static initializer, GCC 15's -Wunterminated-string-initialization will only warn if the array lacks the "nonstring" attribute[1]. Mark the arrays with __nonstring to and correctly identify the char array as "not a C string" and thereby eliminate the warning. This effectively reverts the change in 4e7487245abc ("vboxsf: fix building with GCC 15"), to add the annotation that has other uses (i.e. warning if the string is ever used with C string APIs).

2025-03-10afs: Fix afs_atcell_get_link() to handle RCU pathwalkDavid Howells4-10/+22
The ->get_link() method may be entered under RCU pathwalk conditions (in which case, the dentry pointer is NULL). This is not taken account of by afs_atcell_get_link() and lockdep will complain when it tries to lock an rwsem. Fix this by marking net->ws_cell as __rcu and using RCU access macros on it and by making afs_atcell_get_link() just return a pointer to the name in RCU pathwalk without taking net->cells_lock or a ref on the cell as RCU will protect the name storage (the cell is already freed via call_rcu()).
