Cross-filed case 01566784 on the Red Hat customer portal. Robert, Are you able to provide the raw audit messages when in permissive mode? logrotate -d -f /etc/logrotate.conf Unfortunately '-d' avoids that anything is being done. I just tried '-f' now, but this didn't bring any audit denied. Will check with my colleague tomorrow how to reproduce in a non-production environment best :) I believe that's the same problem as described in BZ#1283134. Any logrotate script which runs su directly or indirectly will trigger such AVC. *** This bug has been marked as a duplicate of bug 1283134 *** |
Description of problem: After installing the rabbitmq-server, the logrotate fails on RHEL 7 daily with an e-mail like this: --- snipp --- Date: Wed, 13 Jan 2016 03:38:10 +0100 (CET) From: Anacron <root.net> To: root.net Subject: Anacron job 'cron.daily' on tux.example.net Message-Id: <20160113023810.77068405B3.net> /etc/cron.daily/logrotate: su: avc.c:74: avc_context_to_sid_raw: Assertion `avc_running' failed. /usr/sbin/rabbitmqctl: line 44: 9328 Aborted su rabbitmq -s /bin/sh -c "/usr/lib/rabbitmq/bin/${SCRIPT} ${CMDLINE}" error: error running shared postrotate script for '/var/log/rabbitmq/*.log ' --- snapp --- type=AVC msg=audit(1452737286.080:2916): avc: denied { create } for pid=21548 comm="su" scontext=system_u:system_r:logrotate_t:s0-s0:c0.c1023 tcontext=system_u:system_r:logrotate_t:s0-s0:c0.c1023 tclass=netlink_selinux_socket type=SYSCALL msg=audit(1452737286.080:2916): arch=c000003e syscall=41 success=no exit=-13 a0=10 a1=80003 a2=7 a3=1 items=0 ppid=21536 pid=21548 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=74 comm="su" exe="/usr/bin/su" subj=system_u:system_r:logrotate_t:s0-s0:c0.c1023 key=(null) type=USER_AVC msg=audit(1452737286.080:2917): pid=21548 uid=0 auid=0 ses=74 subj=system_u:system_r:logrotate_t:s0-s0:c0.c1023 msg='avc: can't open netlink socket: 13 (Permission denied) exe="/usr/bin/su" sauid=0 hostname=? addr=? terminal=?' type=ANOM_ABEND msg=audit(1452737286.081:2918): auid=0 uid=0 gid=0 ses=74 subj=system_u:system_r:logrotate_t:s0-s0:c0.c1023 pid=21548 comm="su" reason="memory violation" sig=6 Version-Release number of selected component (if applicable): selinux-policy-targeted-3.13.1-60.el7.noarch rabbitmq-server-3.3.5-15.el7.noarch How reproducible: Everytime during logrotate, see above and below Actual results: Missing SELinux context transition from logrotate to RabbitMQ. Expected results: SELinux context transition from logrotate to RabbitMQ or some exception. Additional info: Above AVC denied messages where gathered while SELinux was enforced, it seems like the rabbitmq-server is still working without impact (as far as we can tell currently). Nevertheless the SELinux policy should address this one or the other way for the future.
