[ Upstream commit 744375343662058cbfda96d871786e5a5cbe1947 ] Mark ntfs dirty in this case. Rename ntfs_filldir to ntfs_dir_emit. Signed-off-by: Konstantin Komarov Signed-off-by: Sasha Levin

fs/ntfs3: One more reason to mark inode bad

2024-09-12T09:12:51Z

[ Upstream commit a0dde5d7a58b6bf9184ef3d8c6e62275c3645584 ] In addition to returning an error, mark the node as bad. Signed-off-by: Konstantin Komarov Signed-off-by: Sasha Levin

fs/ntfs3: Do copy_to_user out of run_lock

[ Upstream commit d57431c6f511bf020e474026d9f3123d7bfbea8c ] In order not to call copy_to_user (from fiemap_fill_next_extent) we allocate memory in the kernel, fill it and copy it to user memory after up_read(run_lock).

fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed

2024-08-03T07:00:45Z

commit 2fef55d8f78383c8e6d6d4c014b9597375132696 upstream. If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page().

fs/ntfs3: Keep runs for $MFT::$ATTR_DATA and $MFT::$ATTR_BITMAP

2024-08-03T07:00:25Z

[ Upstream commit eb95678ee930d67d79fc83f0a700245ae7230455 ] We skip the run_truncate_head call also for $MFT::$ATTR_BITMAP. Otherwise wnd_map()/run_lookup_entry will not find the disk position for the bitmap parts.

fs/ntfs3: Missed error return

fs/ntfs3: Fix the format of the "nocase" mount option

2024-08-03T07:00:25Z

[ Upstream commit d392e85fd1e8d58e460c17ca7d0d5c157848d9c1 ] The 'nocase' option was mistakenly added as fsparam_flag_no with the 'no' prefix, causing the case-insensitive mode to require the 'nonocase' option to be enabled.
