Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
As things are, rhnsd in RHEL-6.4 runs as rhsmcertd_t (Why rhsmcertd_t anyway?
rhnsd and rhsm are different things really) and produces the following
denial when attempting to install a package (previously scheduled action):
type=AVC msg=audit(1347930972.794:18394): avc: denied { transition } for pid=6780 comm="rhn_check" path="/bin/bash" dev=dm-0 ino=29780 scontext=unconfined_u:system_r:rhsmcertd_t:s0 tcontext=unconfined_u:system_r:rpm_script_t:s0 tclass=process
Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-162.el6
How reproducible:
Always
Steps to Reproduce:
1. RHEL-6.4, registered to RHN / RHN Satellite, running rhnsd
2. Schedule a package installation
3. Wait for rhnsd to wake up and run rhn_check
Actual results:
The SELinux denial above.
Expected results:
No denials.
Additional info:
N/A

I believe confining rhnsd is not a RHEL 6.4 material and the labelling should be reverted in selinux-policy. We should see the change in Fedora for some time before potentially breaking the way our customers deploy package updates to their RHEL machines.
unconfined_domain(rhsmcertd_t)
Is in RHEL6.4
/usr/bin/rhsmcertd -- gen_context(system_u:object_r:rhsmcertd_exec_t,s0)
Must be running rhn_check.
Miroslav we should have
rpm_domtrans(rhsmcertd_t)
I still don't understand -- and would very much like to have it answered --
why rhnsd (part of rhn-client-tools) should run under rhsmcertd_t (judging
by the name a type created for subscription-manager -- a different package
doing different things).
/usr/bin/rhsmcertd certainly does not execute rhn_check as comment #2 suggests.
It's the rhnsd daemon that executes rhn_check. In the current setup, adding
rpm_domtrans(rhsmcertd_t)
would allow it for both rhnsd and subscription-manager, even if the later one
may not need it at all.
Thanks.
We have already discussed this issue.
The original bug is
https://bugzilla.redhat.com/show_bug.cgi?id=834994
I decided to treat rhnsd policy with rhsmcertd policy.
Now I see we should have the rhnsd policy and this policy should have
rpm_domtrans(rhnsd_t)
This is also reason why we have "TestOnly bugs"
https://bugzilla.redhat.com/show_bug.cgi?id=846002
to find these issues in this RHEL6 phase when we have a time to fix it.
Thank you guys for testing. Will do a new RHEL6 build with a new policy soon.
Now just execute
# chcon -t bin_t /usr/sbin/rhnsd
