ni_fname_name called ntfs_cmp_names_cpu which assumes that the first string is in CPU byte order and the second one in little endian. In this case both strings are little endian so ntfs_cmp_names is the correct function to call. Signed-off-by:

When PAGE_SIZE is 64K, if read_log_page is called by log_read_rst for the first time, the size of *buffer would be equal to DefaultLogPageSize(4K).But for *buffer operations like memcpy, if the memory area size(n) which being assigned to buffer is larger than 4K (log->page_size(64K) or bytes(64K-page_off)), it will cause an out of boundary error. Call trace: [...] kasan_report+0x44/0x130 check_memory_region+0xf8/0x1a0 memcpy+0xc8/0x100 ntfs_read_run_nb+0x20c/0x460 read_log_page+0xd0/0x1f4 log_read_rst+0x110/0x75c log_replay+0x1e8/0x4aa0 ntfs_loadlog_and_replay+0x290/0x2d0 ntfs_fill_super+0x508/0xec0 get_tree_bdev+0x1fc/0x34c [...] Fix this by setting variable r_page to NULL in log_read_rst.

Daniel Pinto authored
NTFS-3G provides the system.ntfs_attrib_be extended attribute, which has the same value as system.ntfs_attrib but represented in big-endian. Some utilities rely on the existence of this extended attribute. Improves compatibility with NTFS-3G by adding the system.ntfs_attrib_be extended attribute. Signed-off-by:

The hidedotfiles mount option provides the same functionality as the NTFS-3G hide_dot_files mount option. As such, it should be named the same for compatibility with NTGS-3G. Rename the hidedotfiles to hide_dot_files for compatbility with NTFS-3G. Signed-off-by:

Add documentation for the hidedotfiles mount option. Signed-off-by:
-
Daniel Pinto authored
Currently, the ntfs3 driver does return the hidedotfiles mount option in the list of enabled mount options. This can confuse users who may doubt they enabled the option when not seeing in the list provided by the mount command. Add hidedotfiles mount option to the list of enabled options provided by the mount command when it is enabled. Signed-off-by:
-
Daniel Pinto authored
Currently, the hidedotfiles mount option only has an effect when creating new files. Removing or adding the starting dot when moving or renaming files does not update the hidden attribute. Make hidedotfiles also set or uset the hidden attribute when a file gains or loses its starting dot by being moved or renamed. Signed-off-by:
-
Daniel Pinto authored
Currently, the hidedotfiles mount option is behaving in the reverse way of what would be expected: enabling it disables setting the hidden attribute on files or directories with names starting with a dot and disabling it enables the setting. Reverse the behaviour of the hidedotfiles mount option so it matches what is expected. Signed-off-by:

When enabled, the windows_names mount option prevents the creation of files or directories with names not allowed by Windows. Use the same option name as NTFS-3G for compatibility. Signed-off-by:

The data_size and valid_size fields of non resident attributes should be less than the its alloc_size field, but this is not checked in ntfs_read_mft function. Syzbot reports a allocation order warning due to a large unchecked value of data_size getting assigned to inode->i_size which is then passed to kcalloc. Add sanity check for ensuring that the data_size and valid_size fields are not larger than alloc_size field.

Syzbot reports an out of bound access in ntfs_trim_fs. The cause of this is using a loop termination condition that compares window index (iw) with wnd->nbits instead of wnd->nwnd, due to which the index used for wnd->free_bits exceeds the size of the array allocated. Fix the loop condition.

Yet the problem is that during enumerating attributes in record, kernel doesn't check whether run_off field loading from the disk is a valid value. To be more specific, if attr->nres.run_off is larger than attr->size, kernel will passes an invalid argument run_buf_size in run_unpack_ex(), which having an integer overflow. Then this invalid argument will triggers the slab-out-of-bounds Read bug as above.

Although the attribute name length is checked before comparing it to some common names (e.g., $I30), the offset isn't. This adds a sanity check for the attribute name offset, guarantee the validity and prevent possible out-of-bound memory accesses.

This adds a sanity check for the i_op pointer of the inode which is returned after reading Root directory MFT record. We should check the i_op is valid before trying to create the root dentry, otherwise we may encounter a NPD while mounting a image with a funny Root directory MFT record.
