fs/ntfs3: Break dir enumeration if directory contents error

2024-05-24T09:50:12Z

If we somehow attempt to read beyond the directory size, an error is supposed to be returned. However, in some cases, read requests do not stop and instead enter into a loop. To avoid this, we set the position in the directory to the end. Signed-off-by: Konstantin Komarov Cc: stable@vger.kernel.org

ntfs3: add legacy ntfs file operations

fs/ntfs3: Add ioctl operation for directories (FITRIM)

2024-01-29T09:05:09Z

While ntfs3 supports discards, FITRIM ioctl() command has defined only for regular files. This may confuse users trying to invoke `fstrim` utility with the directory argument (for example, call `fstrim ` which is the common practice). In this case, ioctl() returns -ENOTTY without any error messages in kernel ring buffer, this may be easily interpreted as no support for discards in ntfs3 driver. Currently only FITRIM command implemented in ntfs_ioctl() and passed inode used only for dereferencing NTFS superblock, so no need for separate ioctl() handler for directories, just add existing ntfs_ioctl() handler to ntfs_dir_operations.

fs/ntfs3: Modified fix directory element type detection

2023-12-06T14:46:07Z

Unfortunately reparse attribute is used for many purposes (several dozens). It is not possible here to know is this name symlink or not. To get exactly the type of name we should to open inode (read mft). getattr for opened file (fstat) correctly returns symlink. Signed-off-by: Konstantin Komarov
