2022-03-23erofs-utils: mkfs: rename ctime to mtimeDavid Anderson
Currently mkfs.erofs picks up whatever the system time happened to be when the input file structure was created. Since there's no (easy) way for userspace to control ctime, there's no way to control the per-file ctime that mkfs.erofs uses. In preparation for switching to mtime, rename the "ctime" members of the inode structure.

2022-01-31UPSTREAM: erofs-utils: add missing errors and normalize errors to lower-caseIgor Ostapenko
* Added useful error messages. * Most errors start with lower-case, let's make all non-summarizing error messages lower-case for better consistency. * Sorted default values in fsck's main function to match the struct.

2022-01-31UPSTREAM: erofs-utils: fsck: fix issues related to --extract=XIgor Ostapenko
* Added tar-like default behaviors for --[no-]preserve options: normal user - uses user's owner ID + umask on perms by default; root user - preserve original owner IDs + perms by default; and add appropriate error message when used without --extract=X. * "--[no-]same-owner" and "--[no-]same-permissions" were renamed to "--[no-]preserve-owner" and "--[no-]preserve-perms" to better represent what these options do, the word "same" is ambiguous and tells nothing to the user ("same" to what?). * Added "--[no-]preserve" as shortcuts for both options in one. * Fixed option descriptions as they had typos and were too ambiguous ("extract information" to where? separate file?). * Added --force option to allow extracting directly to root path.

2022-01-31UPSTREAM: erofs-utils: fsck: add --extract=X support to extract to path XIgor Ostapenko
Add support to extract directories, regular files and symlinks. Allocation for extract_path is done only once, then the buffer is reused. Raw and compressed data chunks are handled with a unified function to avoid code duplication, compressed data is verified linearly (with EROFS_GET_BLOCKS_FIEMAP) instead of lookback, as it's problematic to extract data when looking backwards.

2022-01-31UPSTREAM: erofs-utils: fsck: convert to use erofs_iterate_dir()Gao Xiang
No need to open code after erofs_iterate_dir() is finalized in liberofs. However, there are still some TODOs for fsck: - Avoid too deep recursive traversal, sceptically forming a loop; - Check link counts at runtime to keep consistency; - Check if any ftype / i_mode mismatches.
