[v7,00/10] NTFS read-write driver GPL implementation by Paragon Software

Message

Konstantin Komarov Sept. 25, 2020, 3:55 p.m. UTC

This patch adds NTFS Read-Write driver to fs/ntfs3.

Having decades of expertise in commercial file systems development and huge
test coverage, we at Paragon Software GmbH want to make our contribution to
the Open Source Community by providing implementation of NTFS Read-Write
driver for the Linux Kernel.

This is fully functional NTFS Read-Write driver. Current version works with
NTFS(including v3.1) and normal/compressed/sparse files and supports journal replaying.

We plan to support this version after the codebase once merged, and add new
features and fix bugs. For example, full journaling support over JBD will be
added in later updates.

v2:
 - patch splitted to chunks (file-wise)
 - build issues fixed
 - sparse and checkpatch.pl errors fixed
 - NULL pointer dereference on mkfs.ntfs-formatted volume mount fixed
 - cosmetics + code cleanup

v3:
 - added acl, noatime, no_acs_rules, prealloc mount options
 - added fiemap support
 - fixed encodings support
 - removed typedefs
 - adapted Kernel-way logging mechanisms
 - fixed typos and corner-case issues

v4:
 - atomic_open() refactored
 - code style updated
 - bugfixes

v5:
- nls/nls_alt mount options added
- Unicode conversion fixes
- Improved very fragmented files operations
- logging cosmetics

v6:
- Security Descriptors processing changed
  added system.ntfs_security xattr to set
  SD
- atomic_open() optimized
- cosmetics

v7:
- Security Descriptors validity checks added (by Mark Harmstone)
- atomic_open() fixed for the compressed file creation with directio
  case
- remount support
- temporarily removed readahead usage
- cosmetics

Hi Joe. Thanks a lot! Added both Anton and linux-ntfs-dev to the v8 cc list.
Hi Anton. Did you have a chance to look at NTFS3 code?

Thanks.
