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 Lukas Vrabec 2016-09-02 10:56:24 UTC 
+++ This bug was initially created as a clone of Bug #1371512 +++

Description of problem:
I tried to build a Docker image with a Dockerfile that uses makepkg, from ArchLinux.
SELinux is preventing makepkg from 'send' accesses on the message Unknown.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that makepkg should be allowed send access on the Unknown msg 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:
# ausearch -c 'makepkg' --raw | audit2allow -M my-makepkg
# semodule -X 300 -i my-makepkg.pp

The end of logs of the build attempt was:

==> Entering fakeroot environment...
libfakeroot, when sending message: Permission denied

https://github.com/fedora-selinux/selinux-policy/pull/151

We need to get this fix into all Fedora and RHEL7 packages.

--- Additional comment from Daniel Walsh on 2016-08-30 15:47:55 EDT ---

Laurent add this permissions by hand for now using audit2allow.

grep msg /var/log/audit/audit.log | audit2allow -M mymsg
semodule -i mymsg.pp
