reiserfs: fix uninit-value in comp_keys

2024-08-19T04:04:26+00:00

[ Upstream commit dd8f87f21dc3da2eaf46e7401173f935b90b13a8 ] The cpu_key was not initialized in reiserfs_delete_solid_item(), which triggered this issue.

quota: Properly annotate i_dquot arrays with __rcu

2024-03-26T22:19:46+00:00

[ Upstream commit ccb49011bb2ebfd66164dbf68c5bff48917bb5ef ] Dquots pointed to from i_dquot arrays in inodes are protected by dquot_srcu. Annotate them as such and change .get_dquots callback to return properly annotated pointer to make sparse happy.

reiserfs: Avoid touching renamed directory if parent does not change

2024-02-05T20:14:26+00:00

[ Upstream commit 49db9b1b86a82448dfaf3fcfefcf678dee56c8ed ] The VFS will not be locking moved directory if its parent does not change. Change reiserfs rename code to avoid touching renamed directory if its parent does not change as without locking that can corrupt the filesystem.

reiserfs: Replace 1-element array with C99 style flex-array

2023-09-11T12:07:46+00:00

UBSAN found the following issue: ================================================================================ UBSAN: array-index-out-of-bounds in fs/reiserfs/journal.c:4166:22 index 1 is out of range for type '__le32 [1]' This is because struct reiserfs_journal_desc uses 1-element array for dynamically sized array member, j_realblock. This patch fixes this issue by replacing the 1-element array member with C99 style flex-array. This patch also fixes the same issue in struct reiserfs_journal_commit as the same manner.

Pull misc vfs updates from Christian Brauner: "This contains the usual miscellaneous features, cleanups, and fixes for vfs and individual filesystems. Features: - Block mode changes on symlinks and rectify our broken semantics - Report file modifications via fsnotify() for splice - Allow specifying an explicit timeout for the "rootwait" kernel command line option. This allows to timeout and reboot instead of always waiting indefinitely for the root device to show up - Use synchronous fput for the close system call Cleanups: - Get rid of open-coded lockdep workarounds for async io submitters and replace it all with a single consolidated helper - Simplify epoll allocation helper - Convert simple_write_begin and simple_write_end to use a folio - Convert page_cache_pipe_buf_confirm() to use a folio - Simplify __range_close to avoid pointless locking - Disable per-cpu buffer head cache for isolated cpus - Port ecryptfs to kmap_local_page() api - Remove redundant initialization of pointer buf in pipe code - Unexport the d_genocide() function which is only used within core vfs - Replace printk(KERN_ERR) and WARN_ON() with WARN() Fixes: - Fix various kernel-doc issues - Fix refcount underflow for eventfds when used as EFD_SEMAPHORE - Fix a mainly theoretical issue in devpts - Check the return value of __getblk() in reiserfs - Fix a racy assert in i_readcount_dec - Fix integer conversion issues in various functions - Fix LSM security context handling during automounts that prevented NFS superblock sharing" * tag 'v6.6-vfs.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (39 commits) cachefiles: use kiocb_{start,end}_write() helpers ovl: use kiocb_{start,end}_write() helpers aio: use kiocb_{start,end}_write() helpers io_uring: use kiocb_{start,end}_write() helpers fs: create kiocb_{start,end}_write() helpers fs: add kerneldoc to file_{start,end}_write() helpers io_uring: rename kiocb_end_write() local helper splice: Convert page_cache_pipe_buf_confirm() to use a folio libfs: Convert simple_write_begin and simple_write_end to use a folio fs/dcache: Replace printk and WARN_ON by WARN fs/pipe: remove redundant initialization of pointer buf fs: Fix kernel-doc warnings devpts: Fix kernel-doc warnings doc: idmappings: fix an error and rephrase a paragraph init: Add support for rootwait timeout parameter vfs: fix up the assert in i_readcount_dec fs: Fix one kernel-doc comment docs: filesystems: idmappings: clarify from where idmappings are taken fs/buffer.c: disable per-CPU buffer_head cache for isolated CPUs vfs, security: Fix automount superblock LSM init problem, preventing NFS sb sharing ...

fs: add CONFIG_BUFFER_HEAD

2023-08-02T15:13:09+00:00

Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.

reiserfs: Replace one-element array with flexible-array member

2023-07-12T19:09:46+00:00

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in direntry_uarea structure, and refactor the rest of the code, accordingly. Worth mentioning is that before these changes, the original implementation was returning two-too many bytes in function direntry_create_vi(): fs/reiserfs/item_ops.c:464: int size = sizeof(struct direntry_uarea); ... fs/reiserfs/item_ops.c-490- size += (dir_u->entry_count * sizeof(short)); ... fs/reiserfs/item_ops.c-517- return size; Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/290 Reviewed-by: Kees Cook Signed-off-by: Gustavo A.
