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 of problem:
I'm getting denials like this in /var/log/audit/audit.log, causing a bad rotation in the rabbitmq logs, because SELinux is preventing the postrotate of those logs.
In /var/log/audit/audit.log:
type=USER_AVC msg=audit(1494639849.391:137160): pid=21406 uid=0 auid=0 ses=10767 subj=system_u:system_r:logrotate_t:s0-s0:c0.c1023 msg='avc: denied { passwd } for scontext=system_u:system_r:logrotate_t:s0-s0:c0.c1023 tcontext=system_u:system_r:logrotate_t:s0-s0:c0.c1023 tclass=passwd exe="/usr/bin/su" sauid=0 hostname=? addr=? terminal=?'
Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-102.el7_3.16.noarch
How reproducible:
I'm seeing this only when logrotate is configured in /etc/cron.daily. You can probably see these denials trying to execute a postrotate that uses "su"
Additional info:
This was already reported and fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1354347 and https://bugzilla.redhat.com/show_bug.cgi?id=1283134 but I'm still seeing the problem.
In addition I have this custom module enabled (and it doesn't make any difference)
module local_rabbitmq_logrotate 1.0;
require {
type logrotate_t;
class passwd passwd;
}
#============= logrotate_t ==============
allow logrotate_t self:passwd passwd;

Luis,
Could you run:
# semodule -DB
And then try to reproduce the scenario. Some of the SELinux denials can be dontaudited.
Could you attach these denials?
Thanks.
I attached the audit.log with what I think they are the relevant logs. Let me know if you need anything else, or if you need more lines from the audit.log.
