Merge tag 'ntfs-for-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfsPull ntfs updates from Namjae Jeon: "This contains improvements to compression support, metadata handling, error propagation, and filesystem robustness. New feature: - Add optional read support for Windows System Compression (WOF) Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading WOF-compressed files through the NTFS page-read path. This includes parsing REPARSE_TAG_WOF, handling resident and non-resident WOF metadata and compressed chunks, and adding kernel-side XPRESS 4K/8K/16K and LZX 32K decompressors. The codecs use a common transparent compression interface shared with LZNT1. WOF support is read-only and disabled unless explicitly enabled. Other changes: - Harden malformed filesystem handling and error paths. Add bounds and consistency checks for mapping pairs, run lengths, MFT locations, update-sequence offsets, non-resident attributes, compressed attributes, index roots, and bitmap scans. Prevent out-of-bounds accesses in decompression, MFT allocation, and index conversion paths, clean up MFT mappings and attribute search contexts on failure, and propagate attribute and inode initialization errors correctly. - Improve compressed-file I/O path. Fix compressed writes on large-page and highmem systems, reuse compression contexts and output workspaces, avoid unnecessary reads for full-unit overwrites, and submit one bio per compressed write unit. Write replacement data before publishing the new mapping, correctly handle zero-filled compressed blocks, and fix initialized-size and folio state updates after compressed writes. - Synchronize resident reads with MFT record updates. - Validate the final EA stream size before modifying existing data, rewrite the stream safely when replacing entries, restore the previous state when metadata updates fail, and remove the EA attribute pair when the last entry is deleted. - Apply Windows filename restrictions only when windows_names is enabled. - Allow index roots to relocate to extent MFT records when the base record lacks sufficient space. - Move non-resident attribute payload data before shrinking its record. - Correct resident-to-non-resident conversion when compression or sparse flags are enabled. - Prepare file allocation and initialized-size updates before buffered or direct I/O submission, and use pagecache_isize_extended() when extending the file size. - Fix highmem and page/folio access in compressed I/O paths by using the correct local mappings and page helpers. - Apply per-file $LXMOD permissions instead of mount masks when available, and prevent unprivileged writes to reserved $LX* attributes - Update the NTFS maintainer mailing list - Small cleanups"* tag 'ntfs-for-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs: (52 commits) ntfs: support resident WOF decompression ntfs: add non-resident WOF decompression ntfs: implement codec ops for LZX and XPRESS ntfs: port lzx/xpress decompressors from ntfs-3g-system-compression ntfs: return errors from inode initialization ntfs: parse REPARSE_TAG_WOF ntfs: return errors from ntfs_attr_readall ntfs: add WOF compression config option ntfs: define LZNT1 codec ops under transparent codec interface ntfs: introduce transparent compression codec interface ntfs: reject invalid empty mapping pairs ntfs: fix resource leak in ntfs_new_attr_flags ntfs: validate usa_ofs before preserving the update sequence number ntfs: fix off-by-one page overflow in ntfs_decompress() ntfs: do not update ctime when setxattr fails ntfs: reject invalid MFT LCNs from boot sector ntfs: serialize resident iomap reads with mrec_lock ntfs: verify run length exceeding volume boundary ntfs: allow index root relocation ntfs: validate non-resident attribute offsets ...

Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfsPull ntfs resurrection from Namjae Jeon: "Ever since Kari Argillander’s 2022 report [1] regarding the state of the ntfs3 driver, I have spent the last 4 years working to provide full write support and current trends (iomap, no buffer head, folio), enhanced performance, stable maintenance, utility support including fsck for NTFS in Linux. This new implementation is built upon the clean foundation of the original read-only NTFS driver, adding: - Write support: Implemented full write support based on the classic read-only NTFS driver. Added delayed allocation to improve write performance through multi-cluster allocation and reduced fragmentation of the cluster bitmap. - iomap conversion: Switched buffered IO (reads/writes), direct IO, file extent mapping, readpages, and writepages to use iomap. - Remove buffer_head: Completely removed buffer_head usage by converting to folios. As a result, the dependency on CONFIG_BUFFER_HEAD has been removed from Kconfig. - Stability improvements: The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3. All tests passed by ntfs3 are a complete subset of the tests passed by this implementation. Added support for fallocate, idmapped mounts, permissions, and more. xfstests Results report: Total tests run: 787 Passed : 326 Failed : 38 Skipped : 423 Failed tests breakdown: - 34 tests require metadata journaling - 4 other tests: 094: No unwritten extent concept in NTFS on-disk format 563: cgroup v2 aware writeback accounting not supported 631: RENAME_WHITEOUT support required 787: NFS delegation test"Link: https://lore.kernel.org/all/da20d32b-5185-f40b-48b8-2986922d8b25@stargateuniverse.net/ [1][ Let's see if this undead filesystem ends up being of the "Easter miracle" kind, or the "Nosferatu of filesystems" kind... ]* tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs: (46 commits) ntfs: remove redundant out-of-bound checks ntfs: add bound checking to ntfs_external_attr_find ntfs: add bound checking to ntfs_attr_find ntfs: fix ignoring unreachable code warnings ntfs: fix inconsistent indenting warnings ntfs: fix variable dereferenced before check warnings ntfs: prefer IS_ERR_OR_NULL() over manual NULL check ntfs: harden ntfs_listxattr against EA entries ntfs: harden ntfs_ea_lookup against malformed EA entries ntfs: check $EA query-length in ntfs_ea_get ntfs: validate WSL EA payload sizes ntfs: fix WSL ea restore condition ntfs: add missing newlines to pr_err() messages ntfs: fix pointer/integer casting warnings ntfs: use ->mft_no instead of ->i_ino in prints ntfs: change mft_no type to u64 ntfs: select FS_IOMAP in Kconfig ntfs: add MODULE_ALIAS_FS ntfs: reduce stack usage in ntfs_write_mft_block() ntfs: fix sysctl table registration and path ...
