Description "FeRD" (Frank Dana) 2021-11-23 05:36:42 UTC
Description of problem:
Occurred on first boot into Fedora 35 after a `dnf system-upgrade` from F34.
SELinux is preventing gst-plugin-scan from 'open' accesses on the file /proc/sys/vm/mmap_min_addr.

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

If you believe that gst-plugin-scan should be allowed open access on the mmap_min_addr file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'gst-plugin-scan' --raw | audit2allow -M my-gstpluginscan
# semodule -X 300 -i my-gstpluginscan.pp
