Hey Linus,
the fixes tree was filled before Link: tags were ousted. Only one of
the patches in the series carries a Link: tag and that one actually has
a useful discussion attached to it.
Please also be aware that patches in the various branches for the v6.18
merge window will have Link: tags applied and I don't want to rebase
them all just to drop them. I'll mention that during the merge window
once more as a reminder.
Going forward no tags are applied to individual commits. But I will
continue adding tags to the cover letter in the merge message for patch
series as I often modify the merge message so they point back to the
original cover letter.
/* Summary */
This contains a few fixes for this cycle:
# 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.
