-From fb0b47fecc2ca9a36ce3a8e05ab501e2f338d81a Mon Sep 17 00:00:00 2001
-From: "J. Bruce Fields" <bfields@fieldses.org>
-Date: Fri, 1 Sep 2006 18:59:12 -0400
-Subject: [PATCH 01/17] Add nfsv4<->posix acl translation
-
-Add nfs4<->posix acl translation to libacl, so we can present a posix
-acl interface to nfs4 filesystems, which only understand v4 acls.
-
-Original implementation due to Nate Gallaher, based on implementation by
-Marius Eriksen and others, subsequently maintained by Bruce Fields.
-
-Changes:
- - update interface versions and library exports. (Not sure this
- is really right; do we really want to export allo thosesymbols??)
- - Rely on libnfsidmap's notion of a default domain instead of
- hardwiring "CITI.UMICH.EDU".
- - We check whether the filesystem we're on supports nfs4 acl's by
- trying to fe the system.nfs4_acl xattr before falling back on
- posix. Our check was sligh wrong--we should be checking for
- an EOPNOTSUPP as well as an ENOATTR.
- - Call nfs4_init_name_mapping() to read idmapd.conf and set
- defaults before mapping names. (XXX: We're calling it before
- every single mapping, when we should only have to call it once.)
- - Set to zero all bits in the bitmask that aren't assigned a meaning
- by the protocol.
- - Allow default acls of zero length. (We were returning an error
- when the default acl on a directory was length 0, which is actually
- a perfectly normal occurance.)
- - Ignore WRITE_OWNER bit and named attr bits
- - Set DELETE_CHILD on directories with write permissions. (Thanks
- to Simon Vallet <svallet@genoscope.cns.fr> for identifying the
- bug and suggesting this solution.
- - Remove some needless accessor functions.
- - support the acl_extended_file function, so "ls -l" can show that
- neat plus sign after the unix permissions if additional ACLs are
- set (from Christophe Saout <christophe@saout.de>)
- - Remove all native-nfsv4 acl getting/setting code (and all nfsv4
- acl printing code, only used for that); we're doing the native
- NFSv4 ACL stuff in a separate package now.
- - Fix some style problems.
- - Fix handling of inherited aces: the calculated ACL mustn't
- completely replace the existing ACL: instead, setting the default
- ACL should only replace the iherited ACEs (leaving any effective
- permissions untouched), and setting the access ACL should only
- modify effective ACEs (leaving any inherited stuff alone).
