2023-09-28fs/ntfs3: Fix directory element type detectionGabriel Marcano1-1/+5
Calling stat() from userspace correctly identified junctions in an NTFS partition as symlinks, but using readdir() and iterating through the directory containing the same junction did not identify the junction as a symlink. When emitting directory contents, check FILE_ATTRIBUTE_REPARSE_POINT attribute to detect junctions and report them as links.

2023-09-28fs/ntfs3: Fix possible null-pointer dereference in hdr_find_e()Ziqi Zhao1-0/+3
Upon investigation of the C reproducer provided by Syzbot, it seemed the reproducer was trying to mount a corrupted NTFS filesystem, then issue a rename syscall to some nodes in the filesystem. This can be shown by modifying the reproducer to only include the mount syscall, and investigating the filesystem by e.g. `ls` and `rm` commands. As a result, during the problematic call to `hdr_fine_e`, the `inode` being supplied did not go through `indx_init`, hence the `cmp` function pointer was never set. The fix is simply to check whether `cmp` is not set, and return NULL if that's the case, in order to be consistent with other error scenarios of the `hdr_find_e` method. The rationale behind this patch is that: - We should prevent crashing the kernel even if the mounted filesystem is corrupted. Any syscalls made on the filesystem could return invalid, but the kernel should be able to sustain these calls. - Only very specific corruption would lead to this bug, so it would be a pretty rare case in actual usage anyways. Therefore, introducing a check to specifically protect against this bug seems appropriate. Because of its rarity, an `unlikely` clause is used to wrap around this nullity check.

Recently we moved most cleanup from ntfs_put_super() into ntfs3_kill_sb() as part of a bigger cleanup. This accidently also moved dropping inode references stashed in ntfs3's sb->s_fs_info from @sb->put_super() to @sb->kill_sb(). But generic_shutdown_super() verifies that there are no busy inodes past sb->put_super(). Fix this and disentangle dropping inode references from freeing @sb->s_fs_info.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull superblock updates from Christian Brauner: "This contains the super rework that was ready for this cycle. The first part changes the order of how we open block devices and allocate superblocks, contains various cleanups, simplifications, and a new mechanism to wait on superblock state changes. This unblocks work to ultimately limit the number of writers to a block device. Jan has already scheduled follow-up work that will be ready for v6.7 and allows us to restrict the number of writers to a given block device. That series builds on this work right here. The second part contains filesystem freezing updates. Overview: The generic superblock changes are rougly organized as follows (ignoring additional minor cleanups): (1) Removal of the bd_super member from struct block_device. This was a very odd back pointer to struct super_block with unclear rules. For all relevant places we have other means to get the same information so just get rid of this. (2) Simplify rules for superblock cleanup. Roughly, everything that is allocated during fs_context initialization and that's stored in fs_context->s_fs_info needs to be cleaned up by the fs_context->free() implementation before the superblock allocation function has been called successfully. After sget_fc() returned fs_context->s_fs_info has been transferred to sb->s_fs_info at which point sb->kill_sb() if fully responsible for cleanup. Adhering to these rules means that cleanup of sb->s_fs_info in fill_super() is to be avoided as it's brittle and inconsistent. Cleanup shouldn't be duplicated between sb->put_super() as sb->put_super() is only called if sb->s_root has been set aka when the filesystem has been successfully born (SB_BORN). That complexity should be avoided. This also means that block devices are to be closed in sb->kill_sb() instead of sb->put_super(). More details in the lower section. (3) Make it possible to lookup or create a superblock before opening block devices There's a subtle dependency on (2) as some filesystems did rely on fill_super() to be called in order to correctly clean up sb->s_fs_info. All these filesystems have been fixed. (4) Switch most filesystem to follow the same logic as the generic mount code now does as outlined in (3). (5) Use the superblock as the holder of the block device. We can now easily go back from block device to owning superblock. (6) Export and extend the generic fs_holder_ops and use them as holder ops everywhere and remove the filesystem specific holder ops. (7) Call from the block layer up into the filesystem layer when the block device is removed, allowing to shut down the filesystem without risk of deadlocks. (8) Get rid of get_super(). We can now easily go back from the block device to owning superblock and can call up from the block layer into the filesystem layer when the device is removed. So no need to wade through all registered superblock to find the owning superblock anymore" Link: https://lore.kernel.org/lkml/20230824-prall-intakt-95dbffdee4a0@brauner/ * tag 'v6.6-vfs.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (47 commits) super: use higher-level helper for {freeze,thaw} super: wait until we passed kill super super: wait for nascent superblocks super: make locking naming consistent super: use locking helpers fs: simplify invalidate_inodes fs: remove get_super block: call into the file system for ioctl BLKFLSBUF block: call into the file system for bdev_mark_dead block: consolidate __invalidate_device and fsync_bdev block: drop the "busy inodes on changed media" log message dasd: also call __invalidate_device when setting the device offline amiflop: don't call fsync_bdev in FDFMTBEG floppy: call disk_force_media_change when changing the format block: simplify the disk_force_media_change interface nbd: call blk_mark_disk_dead in nbd_clear_sock_ioctl xfs use fs_holder_ops for the log and RT devices xfs: drop s_umount over opening the log and RT devices ext4: use fs_holder_ops for the log device ext4: drop s_umount over opening the log device ...

2023-08-09fs: pass the request_mask to generic_fillattrJeff Layton1-1/+1
generic_fillattr just fills in the entire stat struct indiscriminately today, copying data from the inode. There is at least one attribute (STATX_CHANGE_COOKIE) that can have side effects when it is reported, and we're looking at adding more with the addition of multigrain timestamps. Add a request_mask argument to generic_fillattr and have most callers just pass in the value that is passed to getattr. Have other callers (e.g. ksmbd) just pass in STATX_BASIC_STATS. Also move the setting of STATX_CHANGE_COOKIE into generic_fillattr.

2023-08-02fs: add CONFIG_BUFFER_HEADChristoph Hellwig1-0/+1
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.

2023-07-02fs: ntfs3: Fix possible null-pointer dereferences in mi_read()Jia-Ju Bai1-2/+2
In a previous commit 2681631c2973 ("fs/ntfs3: Add null pointer check to attr_load_runs_vcn"), ni can be NULL in attr_load_runs_vcn(), and thus it should be checked before being used. However, in the call stack of this commit, mft_ni in mi_read() is aliased with ni in attr_load_runs_vcn(), and it is also used in mi_read() at two places: mi_read() rw_lock = &mft_ni->file.run_lock -> No check attr_load_runs_vcn(mft_ni, ...) ni (namely mft_ni) is checked in the previous commit attr_load_runs_vcn(..., &mft_ni->file.run) -> No check Thus, to avoid possible null-pointer dereferences, the related checks should be added. These bugs are reported by a static analysis tool implemented by myself, and they are found by extending a known bug fixed in the previous commit. Thus, they could be theoretical bugs.
