Description Eugene Mah 2022-01-18 11:15:51 UTC 
Description of problem:
started getting sealert reports after installing the latest selinux-policy-35.10-1.fc35
SELinux is preventing pmdakvm from 'search' accesses on the directory /sys/kernel/tracing.

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

If you believe that pmdakvm should be allowed search access on the tracing directory 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 'pmdakvm' --raw | audit2allow -M my-pmdakvm
# semodule -X 300 -i my-pmdakvm.pp
