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 v8: - Compressed files operations fixed v9: - Further cosmetics applied as suggested by Joe Perches v10: - operations with compressed/sparse files on very fragmented volumes improved - reduced memory consumption for above cases v11: - further compressed files optimizations: reads/writes are now skipping bufferization - journal wipe to the initial state optimized (bufferization is also skipped) - optimized run storage (re-packing cluster metainformation) - fixes based on Matthew Wilcox feedback to the v10 - compressed/sparse/normal could be set for empty files with 'system.ntfs_attrib' xattr Konstantin Komarov (10): fs/ntfs3: Add headers and misc files fs/ntfs3: Add initialization of super block fs/ntfs3: Add bitmap fs/ntfs3: Add file operations and implementation fs/ntfs3: Add attrib operations fs/ntfs3: Add compression fs/ntfs3: Add NTFS journal fs/ntfs3: Add Kconfig, Makefile and doc fs/ntfs3: Add NTFS3 in fs/Kconfig and fs/Makefile fs/ntfs3: Add MAINTAINERS Documentation/filesystems/ntfs3.rst | 112 + MAINTAINERS | 7 + fs/Kconfig | 1 + fs/Makefile | 1 + fs/ntfs3/Kconfig | 23 + fs/ntfs3/Makefile | 11 + fs/ntfs3/attrib.c | 1400 +++++++ fs/ntfs3/attrlist.c | 463 +++ fs/ntfs3/bitfunc.c | 135 + fs/ntfs3/bitmap.c | 1504 ++++++++ fs/ntfs3/debug.h | 61 + fs/ntfs3/dir.c | 610 ++++ fs/ntfs3/file.c | 1153 ++++++ fs/ntfs3/frecord.c | 2696 ++++++++++++++ fs/ntfs3/fslog.c | 5221 +++++++++++++++++++++++++++ fs/ntfs3/fsntfs.c | 2565 +++++++++++++ fs/ntfs3/index.c | 2665 ++++++++++++++ fs/ntfs3/inode.c | 2030 +++++++++++ fs/ntfs3/lznt.c | 452 +++ fs/ntfs3/namei.c | 576 +++ fs/ntfs3/ntfs.h | 1262 +++++++ fs/ntfs3/ntfs_fs.h | 988 +++++ fs/ntfs3/record.c | 613 ++++ fs/ntfs3/run.c | 1190 ++++++ fs/ntfs3/super.c | 1479 ++++++++ fs/ntfs3/upcase.c | 77 + fs/ntfs3/xattr.c | 1069 ++++++ 27 files changed, 28364 insertions(+) create mode 100644 Documentation/filesystems/ntfs3.rst create mode 100644 fs/ntfs3/Kconfig create mode 100644 fs/ntfs3/Makefile create mode 100644 fs/ntfs3/attrib.c create mode 100644 fs/ntfs3/attrlist.c create mode 100644 fs/ntfs3/bitfunc.c create mode 100644 fs/ntfs3/bitmap.c create mode 100644 fs/ntfs3/debug.h create mode 100644 fs/ntfs3/dir.c create mode 100644 fs/ntfs3/file.c create mode 100644 fs/ntfs3/frecord.c create mode 100644 fs/ntfs3/fslog.c create mode 100644 fs/ntfs3/fsntfs.c create mode 100644 fs/ntfs3/index.c create mode 100644 fs/ntfs3/inode.c create mode 100644 fs/ntfs3/lznt.c create mode 100644 fs/ntfs3/namei.c create mode 100644 fs/ntfs3/ntfs.h create mode 100644 fs/ntfs3/ntfs_fs.h create mode 100644 fs/ntfs3/record.c create mode 100644 fs/ntfs3/run.c create mode 100644 fs/ntfs3/super.c create mode 100644 fs/ntfs3/upcase.c create mode 100644 fs/ntfs3/xattr.c -- 2.25.4
