[PATCH v3 0/9] xfsprogs: support fscrypt API additions in xfs_io

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
