Merge tag 'vfs-6.17-rc6.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
"fuse:
- Prevent opening of non-regular backing files.
Fuse doesn't support non-regular files anyway.
- Check whether copy_file_range() returns a larger size than
requested.
- Prevent overflow in copy_file_range() as fuse currently only
supports 32-bit sized copies.
- Cache the blocksize value if the server returned a new value as
inode->i_blkbits isn't modified directly anymore.
- Fix i_blkbits handling for iomap partial writes.
By default i_blkbits is set to PAGE_SIZE which causes iomap to mark
the whole folio as uptodate even on a partial write. But fuseblk
filesystems support choosing a blocksize smaller than PAGE_SIZE
risking data corruption. Simply enforce PAGE_SIZE as blocksize for
fuseblk's internal inode for now.
- Prevent out-of-bounds acces in fuse_dev_write() when the number of
bytes to be retrieved is truncated to the fc->max_pages limit.
virtiofs:
- Fix page faults for DAX page addresses.
Misc:
- Tighten file handle decoding from userns.
Check that the decoded dentry itself has a valid idmapping in the
user namespace.
- Fix mount-notify selftests.
- Fix some indentation errors.
- Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability.
This will be moved to an FOP_* flag with a bit more rework needed
for that to happen not suitable for a fix.
- Don't silently ignore metadata for sync read/write.
- Don't pointlessly log warning when reading coredump sysctls"
