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 Ondrej Moriš 2015-01-22 15:44:44 UTC
Description of problem:

The following AVC appears when ipsec is restarted:

type=AVC msg=audit(1421941324.062:4592): avc:  denied  { write } for  pid=26818 comm="ip" path="/var/log/pluto.log" dev="dm-6" ino=147 scontext=system_u:system_r:ifconfig_t:s0-s15:c0.c1023 tcontext=system_u:object_r:ipsec_log_t:s0 tclass=file

The following rule solves the problem:

#============= init_t ==============
allow init_t ipsec_var_run_t:sock_file read;

Version-Release number of selected component (if applicable):

selinux-policy-3.13.1-19.el7.noarch

Comment 1 Miroslav Vadkerti 2015-01-22 15:52:44 UTC
The correct AVC, please ignore the one from the description

This module fixes the issue for us:

module whack 1.0;

require {
        type ipsec_var_run_t;
        type init_t;
        class sock_file read;
}

#============= init_t ==============
allow init_t ipsec_var_run_t:sock_file read;
