cc5b484c2b semanage: correct fcontext auditing
For modify action actually audit the selinux type, i.e. use setype
variable.

For deleting equal fcontext rules do not audit ftype, as the ftype value
for equal rules makes little sense.

7f34831c7b semanage: default to "s0" if serange empty for port modify
In case serange is empty, but the record is beeing modified
(setype was supplied), use default "s0" range. With the original
code the audit event would be printed with no range (i.e.
"system_u:object_r:ssh_port_t:")

Note that default "s0" is currently used in other places
of seobject.py.

Modify setfiles and restorecon to make use of the libselinux
selinux_restorecon* set of functions.

The output from these commands should be much the same as before
with some minor wording changes, the only exceptions being that for
setfiles(8) and restorecon(8) the following options have been added:
1) -I to ignore checking the directory digests.
2) -m to ignore reading /proc/mounts.
These additional options are described in the updated man pages.

671f83b42b policycoreutils/sepolicy: Check get_rpm_nvr_list() return value
get_rpm_nvr_list can fail to get the version of selinux-policy rpm
package, which leads to error during spec file creation (attempt to
invoke __getitem__ of "None" object).

This patch sets the policy number to "0.0.0" in case rpm failed to
get it. This change should be safe because it affects only an example
of spec file.

Variable "POLICYCOREUTILSVER" was removed (unused).

2e60a2c80e policycoreutils: Don't use subprocess.getstatusoutput() in Python 2 code
The commit 7574a50f tried to improve compatibility with Python 3. It changed
the code to use subprocess.getstatusoutput() instead of
commands.getstatusoutput(). Unfortunately subprocess.getstatusoutput() is not
available in Python 2. This patch changes how getstatusoutput() is imported so
the code works on Python 2 and Python 3.

4c5b8a9568 semanage: add auditing of changes in records
Common Criteria requirement FMT_MSA.1 needs any configuration change
that affect enforcement of policy to be audited. This patch adds
auditing of changes in security context mappings for network ports,
interfaces, nodes and file contexts.

A new function log_change is introduced that audits additions,
modification and removal of the mappings via the USER_MAC_CONFIG_CHANGE
audit event.

The format of the audit events was discussed with the audit userspace
maintainer.

This patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=829175

  struct list_node *curr = (*attr_list)->head;

Usages of attr_list_destroy() were called when list_init()
fails.

stack_init() and stack_destroy() also suffered from the
aforementioned issue.

To correct the issue, initialize stack and list variables to

7a137eb75f libsepol/cil: Ignore object_r in userrole mappings when creating policy binary
Commit 77779d2ca, which added support for userattributes in CIL,
accidentally removed code that ignored object_r when adding userrole
mappings to the policydb. This meant that running commands like
`semanage user -l` would incorrectly show object_r. This patch adds that
code back in. Note that CIL requires that these mappings exist to
properly validate file contexts, so pp2cil's behavior of creating these
mappings is not modified.
