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 Derek Ditch 2014-01-15 02:33:41 UTC
Description of problem:
SELinux denying write access to rhsmcertd.

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


How reproducible: Unknown. AVC Denial alert popped up on desktop, presumably after a routine check-in process. I just changed desktop to Gnome 3, but I doubt that is the cause.


Steps to Reproduce:
1. Install RHEL 7
2. ...
3. Receive AVC Denial



Administrator bug output below:
SELinux is preventing /usr/bin/python2.7 from write access on the file /etc/yum.repos.d/redhat.repo.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow python2.7 to have write access on the redhat.repo file
Then you need to change the label on /etc/yum.repos.d/redhat.repo
Do
# semanage fcontext -a -t FILE_TYPE '/etc/yum.repos.d/redhat.repo'
where FILE_TYPE is one of the following: afs_cache_t, cert_t, initrc_tmp_t, puppet_tmp_t, rhsmcertd_lock_t, rhsmcertd_log_t, rhsmcertd_var_lib_t, rhsmcertd_var_run_t, system_conf_t, user_cron_spool_t, var_lock_t. 
Then execute: 
restorecon -v '/etc/yum.repos.d/redhat.repo'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that python2.7 should be allowed write access on the redhat.repo file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep rhsmcertd-worke /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 2 Bryan Kearney 2014-02-10 20:58:22 UTC
We believe this is due to

https://admin.fedoraproject.org/updates/FEDORA-2013-17722/selinux-policy-3.12.1-84.fc20

Moving it to selinux.
