From 16230023e5afcb0b42b8d01207e3449d22772c31 Mon Sep 17 00:00:00 2001

Subject: [PATCH] setfacl: changing owner and when S_ISUID should be set --restore fix
Fix a problem in setfacl --restore when the owner or group is changed
and the S_ISUID and S_ISGID are to be set.
The root of the problem is that chown() can clear the S_ISUID and
S_ISGID bits as described in chown(2):
When the owner or group of an executable file are changed by a
non- superuser, the S_ISUID and S_ISGID mode bits are cleared. POSIX
does not specify whether this also should happen when root does the
chown(); the Linux behavior depends on the kernel version. In case of
a non- group-executable file (i.e., one for which the S_IXGRP bit is
not set) the S_ISGID bit indicates mandatory locking, and is not
cleared by a chown().
To fix the issue re-stat() the file after chown() so that the logic
surrounding the chmod() has the updated mode of the file.

Subject: [PATCH 1/2] libacl: Add acl_extended_file_nofollow()
This function calls lgetxattr() instead of getxattr(), which helps ls(1)
to prevent unnecessary automatic mounts, which acl_extended_file()
triggers. See the following bug report for more details:
https://bugzilla.redhat.com/692982

Subject: [PATCH 2/2] Minor fixes to the previous commit
* Assign the new libacl version ACL_1.2 to acl_extended_file_nofollow
so that package managers will end up with the appropriate
dependencies.
* Add a manpage entry for acl_extended_file_nofollow which sources
("links to") the acl_extended_file manpage.
* Remove the prototype for getxattr/lgetxattr.
* Whitespace cleanups.
