Author: mm Date: Fri Dec 30 22:18:22 2016 New Revision: 310866 URL: https://svnweb.freebsd.org/changeset/base/310866 Log: MFV r310796, r310797: Sync libarchive with vendor. Vendor changes (relevant to FreeBSD): PR #771: Add NFSv4 ACL support to pax and restricted pax NFSv4 ACL information may now be stored to and restored from tar archives. ACL must be non-trivial and supported by the underlying filesystem, e.g. natively by ZFS or by UFS with the NFSv4 ACL enable flag set.
