[gentoo-hardened] Incorrect contexts in /run revisited

[Ben Pritchard]

Hello all

In March, I reported some issues with SELinux contexts in /run. (I seem
to have misplaced the email -- archive at
http://article.gmane.org/gmane.linux.gentoo.hardened/6180).

It look like Sven added the functionality a few months ago, and it is
available in version 2.20140311-r5 (currently ~arch).

Note 1: There are a few pacakges that need this implemented. Fail2ban
is one on my machine. Should I file a bug report (probably against
sec-policy/selinux-fail2ban)?

Note 2: There's possibly a bug in the new tmpfiles module
(policy/modules/system/tmpfiles.fc). I'm not so sure /lib/rc/bin/checkpath
should have context tmpfiles_exec_t. Again, this seems to make several
directories (and maybe files) in /run have context var_run_t.

What I think is happening is that init_daemon_pid_file() only allows
transitions for the initrc_t domain, and checkpath is no longer running in
that domain. Therefore, the file transition from var_run_t to whatever
type is specified as the first argument in init_daemon_pid_file is
not done.

Changing the context of /lib/rc/bin/checkpath to bin_t makes many more
of the files in /run have the correct context again on boot.

(perhaps this belongs on the selinux mailing list?)

Thanks
