Puppetmaster denial for node.rb

Description
I am getting this one:
type=AVC msg=audit(1401094926.717:390): avc: denied { execute } for pid=15328 comm="ruby" name="node.rb" dev=dm-0 ino=2102058 scontext=unconfined_u:system_r:passenger_t:s0 tcontext=system_u:object_r:puppet_etc_t:s0 tclass=file
type=AVC msg=audit(1401094926.717:390): avc: denied { execute_no_trans } for pid=15328 comm="ruby" path="/etc/puppet/node.rb" dev=dm-0 ino=2102058 scontext=unconfined_u:system_r:passenger_t:s0 tcontext=system_u:object_r:puppet_etc_t:s0 tclass=file
I think I saw that previously.

Ok it looks like this was not resolved (see the related bug). We need a rule for this.

Ok the problem appears when node.rb has puppet_etc_t. After we call foreman-selinux-relabel the context is corrected. It looks like we deploy node.rb via puppet, therefore the relabel step is called BEFORE (during foreman-selinux rpm transaction). Thus it has wrong context.

Ignore all the lines except the node.rb - this is bug in RHEL6 which will likely never be fixed: if a context is an alias, then restorecon restores to original context rather than alias.
Rather than relabeling this, I have decided to drop foreman_enc_t and use puppet_etc_t instead. It is not big deal since there are none dangerous executable files with this domain.
Putting the fix into: https://github.com/theforeman/foreman-selinux/pull/18
- Project changed from SELinux to Installer
- Category deleted (
Packaging)
Instead of dropping the type, I will make sure that installer sets proper selinux file label.
- Target version changed from 1.8.2 to 1.8.1
- Status changed from Ready For Testing to Assigned
This issue was NOT fixed in the PR menioned. I need to do seltype in Puppet.
- Status changed from Assigned to Ready For Testing
- Target version changed from 1.8.1 to 1.8.0
Seen on a second run of the installer:
# [ WARN 2014-07-07 14:37:02 verbose] /File[/etc/puppet/node.rb]/seltype: seltype changed 'puppet_etc_t' to 'foreman_enc_t'
This agrees with the theory presented in the PR comments, which is that it's ordering related (node.rb being evaled before foreman-selinux is installed).
- Target version changed from 1.8.0 to 1.7.5
- Status changed from Ready For Testing to Closed
- % Done changed from 0 to 100
- translation missing: en.field_release set to 10
