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.
In Red Hat Enterprise Linux 7.4, an SELinux allow rule for the keepalived utility was missing. Consequently, SELinux denial occurred when keepalived had been run. With this update, the missing rule has been added, and keepalived is now working with SELinux in Enforcing mode.
Description of problem:
In RHEL 7.4, keepalived was rebased to version 1.3.5. After upgrade from RHEL 7.3 with keepalived-1.2.13-9, avc denials started to appear.
Version-Release number of selected component (if applicable):
keepalived-1.3.5-1.el7.x86_64
selinux-policy-3.13.1-166.el7.noarch
How reproducible:
always
Steps to Reproduce:
1. Upgrade to keepalived-1.3.5-1.el7
2. Run keepalived
Actual results:
type=AVC msg=audit(1504016429.630:5751): avc: denied { setpgid } for pid=10662 comm="keepalived" scontext=system_u:system_r:keepalived_t:s0 tcontext=system_u:system_r:keepalived_t:s0 tclass=process
Expected results:
no avc denial
Additional info:
downgrading keepalived to 1.2.13-9 makes the software working again
custom policy based on the avc helps as well
