Note: run the command as subscription-manager config --rhsmcertd.certcheckinterval=3 --rhsmcertd.splay=0 or edit /etc/rhsm/rhsm.conf Commit: 795a04994 Allow subscription-manager execute ip Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: We (subscription-manager team) are working to change how subscription-manager collects network facts, making use of `ip` from the iproute package. When a first draft of the change was tested with QE's help, the result was that rhsmcertd-worker (spawned by rhsmcertd) does now allow this execution -- for example: type=AVC msg=audit(1684773208.054:13797): avc: denied { execute } for pid=57312 comm="rhsmcertd-worke" name="ip" dev="vda1" ino=12803826 scontext=system_u:system_r:rhsmcertd_t:s0 tcontext=system_u:object_r:ifconfig_exec_t:s0 tclass=file permissive=0 The `ip` usage seems to not trigger denials when run from the subscription-manager CLI, e.g. when registering using `subscription-manager register` or a simpler `subscription-manager facts` (to trigger the facts collection). Hence, please allow rhsmcertd-worker to execute/run `ip`. How reproducible: All the time. Steps to Reproduce: 1. Install a version of subscription-manager that uses `ip` to collect network facts 2. Shorten the check-in time of rhsmcertd to e.g. 5 minutes & disable the splay (the randomization of the check-in time within the interval), so you can see the problem quicker than waiting for the default check-in time (which is ~4h): # subscription-manager config --rhsmcertd.certCheckInterval=5 --rhsmcertd.splay=0 3. Restart rhsmcertd: `systemctl restart rhsmcertd.service` 4. Register a system: `subscription-manager register` 5. Wait for 5 minutes Actual results: SELinux denials for the execution of "ip" as shown above. Expected results: No denials.
