Merge tag 'ntfs3_for_7.2' of https://github.com/Paragon-Software-Group/linux-ntfs3
Pull ntfs3 updates from Konstantin Komarov:
"Added:
- depth limit to indx_find_buffer() to prevent stack overflow
- validate split-point offset in indx_insert_into_buffer()
- bounds check to run_get_highest_vcn()
- fileattr_get() and fileattr_set() support
- zero stale pagecache beyond valid data length
- handle delayed allocation overlap in run lookup
- validate lcns_follow in log_replay() conversion
- cap RESTART_TABLE free-chain walker at rt->used
- resize log->one_page_buf when adopting on-disk page size
- reject direct userspace writes to reserved $LX* xattrs
Fixed:
- out-of-bounds read in decompress_lznt()
- avoid -Wmaybe-uninitialized warnings
- hold ni_lock across readdir metadata walk
- preserve non-DOS attribute bits in system.dos_attrib
- validate index entry key bounds
- syncing wrong inode on DIRSYNC cross-directory rename
- validate Dirty Page Table capacity in log_replay() copy_lcns
- wrong LCN in run_remove_range() when splitting a run
- allocate iomap inline_data using alloc_page
- mount failure on 64K page-size kernels
- out-of-bounds read in ntfs_dir_emit() and hdr_find_e()
- bound attr_off in UpdateResidentValue against data_off
- bound DeleteIndexEntryAllocation memmove length
- bound copy_lcns dp->page_lcns[] index in analysis pass
- bound NTFS_DE view.data_off in UpdateRecordData{Root,Allocation}
- prevent potential lcn remains uninitialized
Changed:
- bound to_move in indx_insert_into_root() before hdr_insert_head()
- call _ntfs_bad_inode() when failing to rename
- fold resident writeback into writepages loop
- force waiting for direct I/O completion
- fold file size handling into ntfs_set_size()
- reject SEEK_DATA and SEEK_HOLE past EOF early
- format code, add descriptive comments and remove non-useful"
