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.

Expected results:
* each file that was processed by logrotate should be labelled the same way as before it was processed by logrotate

Comment 2 Miroslav Grepl 2012-04-05 14:45:12 UTC 
Well these log files are created by logrotate. SO you are saying to have

/var/log/zarafa/server.log system_u:object_r:zarafa_server_log_t:s0

/var/log/zarafa/server.log-20120318.gz system_u:object_r:var_log_t:s0

with the same label? If I am right, no way how to do it. Also I believe it does not cause any issues?
Comment 3 Milos Malik 2012-04-05 17:48:59 UTC 
It depends how logrotate is configured, but usually logrotate renames the existing file and new file is created by the program which produces the log messages. Important thing is that logrotate keeps the label untouched. So these log files are labelled correctly until somebody runs "restorecon -R /var/log". Once somebody does that restorecon screws up the labelling. Because restorecon changes labels to var_log_t.

Here are 2 definitions which I believe are correct. No matter what is appended to the filename the file will always be labelled correctly.

/var/log/cluster/dlm_controld\.log.*	--	system_u:object_r:dlm_controld_var_log_t:s0
/var/log/cluster/gfs_controld\.log.*	--	system_u:object_r:gfs_controld_var_log_t:s0

Basically my idea is: if the path pattern ends with "\.log" we should modify it to "\.log.*".
Comment 4 Daniel Walsh 2012-04-09 19:57:20 UTC 
That seems reasonable to me.
Comment 5 Miroslav Grepl 2012-04-10 07:27:50 UTC 
Yes, now it makes sense also for me.
Comment 7 RHEL Program Management 2012-07-10 08:20:12 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 8 RHEL Program Management 2012-07-11 01:55:32 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 9 Miroslav Grepl 2012-07-17 11:02:06 UTC 
We added fixes to Fedora. Will backport.
Comment 12 Miroslav Grepl 2012-11-27 14:44:09 UTC 
Fixed in selinux-policy-3.7.19-182.el6
