I believe the logic in testing the file_contexts fc regular
expression against
candidate home directory listed in /etc/passwd for non-system user may
have a problem.
For example,
I have postgresql installed under /opt/pgsql, database at /pgsql/pgdb
and have a username pgsql, setting the home directory to /pgsql/home.
Currently, FC5 selinux policy has serveral fc rules like this:
/var/lib/pgsql/data/*
Due to the way python's re.search is called, instead of using all
possible
fc rules in file_context to try match the candidate home directory,
it does
it the other way. Resulting in erroneously flagging rule conflict.
Have I confused myself? If not, the following patch will fix the
problem,
which it did for me.
Note that if you do not place home directories away from /home, you may
never experience this problem, and hence has no need for this patch.
