Author: asomers Date: Sun Jun 17 15:22:27 2018 New Revision: 335284 URL: https://svnweb.freebsd.org/changeset/base/335284 Log: audit(4): add tests for extattr_get_file(2) and friends This commit includes extattr_{get_file, get_fd, get_link, list_file, list_fd, list_link}. It does not include any syscalls that modify, set, or delete extended attributes, as those are in a different audit class. Submitted by: aniketpt MFC after: 2 weeks Sponsored by: Google, Inc.
