Hello, This patchset updates xfs_io to support the new fscrypt ioctls that were merged for 5.4 (https://git.kernel.org/torvalds/c/734d1ed83e1f9b7b). New commands are added to wrap the new ioctls to manage filesystem encryption keys: 'add_enckey', 'rm_enckey', and 'enckey_status'. Also, the existing 'get_encpolicy' and 'set_encpolicy' commands are updated to support getting/setting v2 encryption policies. The purpose of all this is to allow xfstests to test these new APIs. Note: currently only ext4, f2fs, and ubifs support encryption. But I was told previously that since the fscrypt API is generic and may be supported by XFS in the future, the command-line wrappers for the fscrypt ioctls should be in xfs_io rather than in xfstests directly (https://marc.info/?l=fstests&m=147976255831951&w=2). This patchset applies to the latest "for-next" branch of xfsprogs (commit ac8b6c380865). It can also be retrieved from tag "fscrypt-key-mgmt-improvements_2019-09-27" of https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/xfsprogs-dev.git Changes v2 => v3: - Generate the encryption modes for 'help set_encpolicy'. - Mention '-a' in all relevant places in the help for rm_enckey. - Mark strings for translation. No changes v1 => v2.
