Description Shawn Kovalchick 2015-08-12 19:39:08 UTC
I am switching from strict to targeted profile.  I have POLICYTYPES="strict targeted" in /etc/portage/make.conf (Used to be strict only)  While reemerging my policy ebuilds, I received the following error during the squid policy build:  

WARN: postinst
SELinux module load failed. Trying full reload...
Failed to reload SELinux policies.

semodule -b base.pp -i $(ls *.pp | grep -v base.pp | grep -v unconfined.pp)

yields the following error message:

Unable to resolve name: httpd_squid_script_exec_t
Failed to resolve filecon statement at 3 of /var/lib/selinux/targeted/tmp/modules/400/squid/cil
Failed to resolve ast
semodule:  Failed!

Reproducible: Always

Steps to Reproduce:
1. emerge -1v sec-policy/selinux-squid
2.
3.
Actual Results:  
Error on install

Expected Results:  
Package installs correctly

Uninstalling package, rebuilding sec-policy/selinux-apache (which is a dependency), then reinstalling fixed the problem.

I would resolve this, but I would like to leave it open in case this is an issue that could be handled programmatically.  Anyway, I'll leave that decision to you learned scholars.

Uninstalling is probably not required, just emerge selinux-apache first then do selinux-squid.

As for why this was not automatic ... I have no idea. The ebuilds have had 
DEPEND="${DEPEND}
	sec-policy/selinux-apache
"
RDEPEND="${RDEPEND}
	sec-policy/selinux-apache
"
in them ever since release 2.20141203-r1 so portage *should* emerge it first.

Did you only "emerge -1v selinux-squid" and hit this error or did you re-emerge all of them with: "emerge -v1 $(qlist -IC sec-policy)"? the latter will re-emerge all of them and should thus do selinux-apache before selinux-squid.
Comment 3 Shawn Kovalchick 2015-08-14 06:55:43 UTC
I don't think the problem was with the dependency.  My theory is that after switching from the strict to the targeted policy, the apache policy bits had not yet been included in whatever was needed for the squid policy to compile. (I'm referring to the semodule command in my initial comment.)  So even though the apache module had been built, the semodule part had not yet run (or maybe it had failed previously and I didn't notice).  Running the semodule command with squid still installed would fail.  After uninstalling squid and rerunning the semodule command, the squid policy installed correctly.

To answer your later question, I ran emerge -1v <<ls from /var/db/whatever/.../sec-policy>>. (I'll note that qlist line for next time).  I thought it rebuilt the apache module first, but I can't be certain.
Comment 4 Sven Vermeulen (RETIRED) gentoo-dev 2015-08-16 16:57:09 UTC
I *think* that the problem is that Portage rebuilds does not honor the dependency tree in the same sense as when the dependency has not been built yet.

When you change POLICY_TYPES="strict" to POLICY_TYPES="strict targeted" and then rebuild the policies, Portage will think that selinux-apache is already installed (when building selinux-squid) so does not 'push' that dependency up the tree. It'll just rebuild it as part of the large rebuild you've done.

Perhaps we should update the documentation to first rebuild the dependency-sensitive ones (i.e. those that are dependencies of others).

From a quick grep this would be:
  sec-policy/selinux-daemontools
  sec-policy/selinux-dbus
  sec-policy/selinux-inetd
  sec-policy/selinux-java
  sec-policy/selinux-kerberos
  sec-policy/selinux-lpd
  sec-policy/selinux-milter
  sec-policy/selinux-remotelogin
  sec-policy/selinux-ucspitcp
  sec-policy/selinux-virt
  sec-policy/selinux-xserver

But it would be even better if this was dynamically calculated in the command.

Perhaps there is even a way to trigger Portage to think the packages are not installed yet?
Comment 5 Shawn Kovalchick 2015-08-16 19:21:24 UTC
Maybe a flag (use flag, feature flag, etc.) could be set instead of a make.conf option.  If the use flag changed, the it would trigger a recompile?

Also, I noticed that selinux-apache was not in your list of dependencies.
