1114864 – SELinux prevents asterisk logrotate script from doing its job

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 Milos Malik 2014-07-01 07:41:38 UTC

Description of problem:
 * asterisk package contains a logrotate script which is regularly processed by logrotate cron job
 * SELinux prevents some of the actions written in the /etc/logrotate.d/asterisk file

Version-Release number of selected component (if applicable):
asterisk-11.10.2-2.fc19.x86_64
logrotate-3.8.6-4.el7.x86_64
selinux-policy-3.12.1-155.el7.noarch
selinux-policy-devel-3.12.1-155.el7.noarch
selinux-policy-doc-3.12.1-155.el7.noarch
selinux-policy-minimum-3.12.1-155.el7.noarch
selinux-policy-mls-3.12.1-155.el7.noarch
selinux-policy-sandbox-3.12.1-155.el7.noarch
selinux-policy-targeted-3.12.1-155.el7.noarch

How reproducible:
always

Steps to Reproduce:
1. get a RHEL-7.0 machine with active targeted policy
2. install asterisk RPM
3. start and stop the asterisk service at least once (to have something in asterisk log files)
4. wait for logrotate cron job to finish or force its execution
5. search for AVCs

Actual results in enforcing mode:

Comment 1 Miroslav Grepl 2014-07-01 08:21:16 UTC

Any idea why abrt-cli is started?

Comment 2 Jakub Filak 2014-09-18 19:05:11 UTC

I presume something sources /etc/profile.d/abrt-console-notification.sh which runs "abrt-cli status --since=$last_login" to notify users about new crashes. I have pushed a patch to the upstream repository which disables this profile.d script if STDOUT is not connected to a terminal:
https://github.com/abrt/abrt/commit/592b7e19a20b38547c5b3c5d81add27ed79e05a9

Milosi, could you please replace your /etc/profile.d/abrt-console-notification.sh with https://github.com/abrt/abrt/blob/master/src/cli/abrt-console-notification.sh, retest and report the results here?
