Description Mikhail 2021-05-20 13:13:04 UTC
Description of problem:
SELinux is preventing gdb from read, open access on the chr_file /dev/dri/renderD128.

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

If you believe that gdb should be allowed read open access on the renderD128 chr_file 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 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

This bug appears to have been reported against 'rawhide' during the Fedora 35 development cycle.
Changing version to 35.
