Eric Paris a8a36f88c2 sepolgen: audit2allow: one role/type pair per line
audit2allow was generating rules which would not compile.  We can only
do one per line, not tons of types at one time.

Manoj Srivastava 98455c5524 sepolgen: fix detection of policy loads
I am running into an issue with sepolgen. Debian ships more
than one version of the refpolicy, a default one, and a MLS enabled
one. So, the include files live in either
/usr/share/selinux/{default,mls}/include sepolgen (in
src/sepolgen/defaults.py) sets refpolicy_devel() to a single
location -- and thus, only one version of the security policy may be
supported. So, sepolgen-ifgen from policycoreutils can only work
with one policy, which may not be the one installed on the target
machine. Could this be made configurable, somehow? As far as I can
see, sepolgen's python library does not offer any way to set the
value. This change fixes that. Now you may set the path to look for
development headers in /etc/selinux/sepolgen.conf, in the variable
SELINUX_DEVEL_PATH. The builtin default will have it work on Debian
and fedora machines out of the box.

Dan Walsh 9cbd404ceb sepolgen: Ignore permissive qualifier if found in an interface
During Rawhide releases we change all "unconfined_domains" to
permissive domains in order to find new AVC messages without breaking
rawhide boxes.  The way we do this is changing the unconfined_domain
interface and putting permissive $1; in it.  sepolgen does not like
this and blows up the build.  This patch tells sepolgen to ignore the
permissive in an interface.

Ok this one only adds a flag to the policygenerator to tell it to

Originally audit2allow used the avc: allowed message generated by
auditallow statement for load_policy to identify policy reloads.  Later
it was switched to use the MAC_POLICY_LOAD events generated by the audit
framework.  Those events should still get logged via printk if auditd is
not running, but it appears that the code (audit_printk_skb) will then
log the type= field as an integer rather than a string, and
audit2allow/sepolgen only looks for the string MAC_POLICY_LOAD.

So I suspect that this would be resolved by modifying sepolgen/audit.py
to also match on type=1403 for load messages.  Try this:
