Description Robert Scheck 2023-06-08 17:06:15 UTC
Description of problem:
While trying to package RIPE Atlas Probe/Anchor for Fedora and EPEL, I had to learn that SELinux labels RIPE Atlas Probe/Anchor's /usr/sbin/ripe-atlas process as zebra_t, which makes RIPE Atlas Probe/Anchor unusable as the SELinux Zebra policy forbids many things RIPE Atlas Probe/Anchor needs to work.

Fortunately, this seems to be an unintended side effect in the SELinux policy as shipped in Fedora and RHEL:

$ grep /usr/sbin/rip /etc/selinux/targeted/contexts/files/file_contexts
/usr/sbin/rip.* --      system_u:object_r:zebra_exec_t:s0
$ 

For the Zebra/FRR component 'rip' (Routing Information Protocol) a wildcard was placed which likely impacts all software starting with '/usr/sbin/rip', even if it's not related to Zebra/FRR at all. Thus I propose the following simple fix, that does not impact Zebra/FRR's 'rip' but unbreaks RIPE Atlas Probe/Anchor's /usr/sbin/ripe-atlas (and I explicitly added a wildcard to cover possible future sub-components as well):

/usr/sbin/ripe-atlas.* -- system_u:object_r:bin_t:s0

Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.14.3-117.el8.noarch

Actual Results:  
SELinux labels RIPE Atlas Probe/Anchor's /usr/sbin/ripe-atlas process as zebra_t when started via ripe-atlas.service

Expected Results:  
SELinux labels RIPE Atlas Probe/Anchor's /usr/sbin/ripe-atlas process as unconfined_t when started via ripe-atlas.service
