What were you trying to do that didn't work?
Run regression tests for SBD component on RHEL 10 Beta.
Please provide the package NVR for which bug is seen:
selinux-policy-40.13.1-1.el10.noarch
How reproducible:
always
Steps to reproduce
Set up and use SBD as a fencing method in the cluster - see for example test job https://beaker.cluster-qe.lab.eng.brq.redhat.com/bkr/jobs/157679.
Looks like the functionality itself is not endangered (test passed), however AVC denials are generated.
SBD package has the same version as in RHEL9.4 (sbd-1.5.2-1.el9.x86_64), where no AVCs were present.
Expected results
No AVC denials
Actual results
