29 * Functions to handle ACLs for bacula.
31 * Currently we support the following OSes:
32 * - AIX (pre-5.3 and post 5.3 acls, acl_get and aclx_get interface)
34 * - FreeBSD (POSIX and NFSv4/ZFS acls)
38 * - Solaris (POSIX and NFSv4/ZFS acls)
41 * Next to OS specific acls we support AFS acls using the pioctl interface.
43 * We handle two different types of ACLs: access and default ACLS.
44 * On most systems that support default ACLs they only apply to directories.
46 * On some systems (eg. linux and FreeBSD) we must obtain the two ACLs
47 * independently, while others (eg. Solaris) provide both in one call.
49 * The Filed saves ACLs in their native format and uses different streams
50 * for all different platforms. Currently we only allow ACLs to be restored
51 * which were saved in the native format of the platform they are extracted
52 * on. Later on we might add conversion functions for mapping from one
53 * platform to an other or allow restores of systems that use the same
56 * Its also interesting to see what the exact format of acl text is on
57 * certain platforms and if they use they same encoding we might allow
58 * different platform streams to be decoded on an other similar platform.
