RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Levente Farkas 2014-07-13 22:09:29 UTC 
i collect a few bug in the current rhel-7 policyes:

restorecond (from policycoreutils-restorecond) can't write it's own pid into restorecond.pid:
#============= restorecond_t ==============
allow restorecond_t var_run_t:file write;

postfix can't read local .forward files eg: /home/lfarkas/.forward even if i relabel the whole home:
#============= postfix_local_t ==============
allow postfix_local_t home_root_t:file getattr;

shorewall can't write it's log files shorewall-init.log:
#============= shorewall_t ==============
allow shorewall_t var_log_t:file { write setattr };

nsd can't patch it's zona files from /etc/cron.hourly/nsd:
#============= nsd_crond_t ==============
allow nsd_crond_t nsd_conf_t:file write;
allow nsd_crond_t nsd_var_run_t:file getattr;

Comment 4 Milos Malik 2014-10-23 11:59:49 UTC 
It seems that you have some mislabeled files on your machine, Please run following command:

# restorecon -Rv /var /run

Please attach AVCs which happen from now on:

# ausearch -m avc -m user_avc -m selinux_err -i -ts today
Comment 5 Miroslav Grepl 2014-10-24 11:12:30 UTC 
Also what does

$ restorecon -R -v /home
Comment 6 Levente Farkas 2014-10-31 20:56:54 UTC 
it;s been a long time ago. it was during the rhel7 beta period i no longer can check that system anymore.
