Thanks; I've provided it for Gentoo users already.

Yesterday I got notified about a vulnerability in libcap-ng & seunshare:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3215

I found quite a lot of chatter on RedHat's bugzilla and several potential
solutions; can we expect that the "proper" solution will be pushed to
policycoreutils soon as well?

The seunshare.c file hasn't been touched in a while so I assume it isn't in
yet.

Wkr,

I will send the patches for seunshare, although the fix was actually in
libcap-ng, which caused seunshare to break.

I had a few issues while getting this release in Gentoo.


https://bugs.gentoo.org/show_bug.cgi?id=467258

- libselinux does not provide selinux_current_policy_path() but this method is
  used in policycoreutils in a number of locations.

I had to take the definition from this method from
http://svnweb.mageia.org/packages/cauldron/libselinux/current/SOURCES/libselinux-rhat.patch?revision=400400&view=co&pathrev=400400
(only included the definition in Gentoo for now). Seems that this is a
much-needed function (otherwise tools like semanage just break).


https://bugs.gentoo.org/show_bug.cgi?id=467264

- using semanage permissive fails with stacktrace referring to a Makefile on
  a non-existing location (/usr/share/selinux/default/Makefile)

I have yet to find the culprit of this (getting late so that'll be for
tomorrow evening).


https://bugs.gentoo.org/show_bug.cgi?id=467268

- policycoreutils' sepolicy command requires yum python bindings

Since yum is not available on Gentoo, is this really necessary?

I suppose this is what I get for testing on Fedora with everything
already installed...

semanage permissive builds a module to make a permissive domain. On
Fedora there is an out-of-tree policy build environment in
/usr/share/selinux. Without this environment it can't build a module.
Does Gentoo have it in a different place or just not at all?

Unfortunate. I'd exclude it for now and hopefully we can work out
making it more distro independent.

In the previous release it worked so I probably need to find where the
location is coded and have that point to
/usr/share/selinux/$SELINUXTYPE/include/Makefile or so. That is the
Makefile used to build (refpolicy-style) policy modules here.

Certainly. I'll see if I can draft up something when I get more familiar
with the required functionalities.

I've been able to get this to work by creating a /etc/selinux/sepolgen.conf
file that contains the following:

SELINUX_DEVEL_PATH=/usr/share/selinux/strict/include

Well, I removed the yum dependency and the __extract_rpms method (+ the
call towards it). But trying to use sepolicy still gives me stacktraces that
I am having difficulties with to debug:

OK, I'll wait for a while more.

In addition, I've forgottn to note the patch.
