Add SYSTEM_SECURITY access flag and use with smb2 when opening files for getting/setting SACLs. Add "system.cifs_ntsd_full" extended attribute to allow user-space access to the functionality. Avoid multiple server calls when setting owner, DACL, and SACL. Signed-off-by: Boris Protopopov <pboris@amazon.com> Signed-off-by: Steve French <stfrench@microsoft.com>
