Talk:PackagingDrafts/SELinux Independent Policy

general questions

• can the reasons for %defattr 755 be explained?
  • No, it was a leftover from selinux-policy.spec and will be removed
• what if one package aims foo-selinux wants to generate foo-selinux-targeted and foo-selinux-mls? (e.g. see copr-selinux) answer: all the %selinux_* macros provide -s option
  • There would be two new .tars and most changes to the spec file would appear twice (once for each package).
  • The naming convention is up to the maintainer. It would probably be best to use "foo-selinux" for the "targeted" policy and "foo-selinux-mls" for "mls"
• shouldn't we move %selinux_relabel_post to %post (instead of %posttrans) or move the %selinux_relabel_pre into %pretrans? The former is much more flexible, but probably a lot less optimal.
  • The selinux_relabel_pre macro takes effect only once per transaction (the first package to use it copies current file_contexts file)
  • This is why selinux_relabel_post is called in posttrans (it evaluates all policy changes in the transaction and relabels files accordingly)
• should packages Recommend/Require the 'foo-selinux' packages? (consider selinux is enforcing, and people install foo-bar package, but forgot to install foo-selinux), edit: I do think that we should use Requires: (foo-selinux-targeted if selinux-policy-targeted), WDYT?
  • Yes, they should. We already started using the rich dependency syntax in one package to test it properly. I'll add it into the guidelines
• can anyone from selinux team review this POC https://pagure.io/copr/copr/pull-request/301 (no matter when)
  • I created a ticket for it in our Jira (it will be assigned during our next planning meeting) https://projects.engineering.redhat.com/browse/SELINUX-1434

policy to sync with global selinux policy?

• do we have to maintain all the .fc paths, also related to e.g. debian (as is done in selinux-policy-targeted)
  • Not sure if I understand the question, but the .fc file is necessary because it completely overrides the .fc contained in selinux-policy-targeted
    • Check e.g. ./policy/modules/services/postgresql.fc, and the line "ifdef(`distro_debian'," ... do we have to cross-sync those parts between postgresql-selinux and selinux-policy-targeted?
• if something changes in say mysql-selinux, do we have to backport it to selinux-policy-targeted upstream?
  • changes should be backported to selinux-policy-targeted
• should we maintain paths for SCLs? Or should each SCL have it's own '*-selinux' package with custom paths?
  • each SCL should have it's own *-selinux package with files stored in the selinux store (/var/lib/selinux)
• should there be e.g. separated policy for mariadb vs. mysql?
  • this is a special case and should be consulted with the SELinux team (in this case there would probably be a shared database-selinux package)
