Description nightly 2023-03-26 11:09:40 UTC
Description of problem:
SELinux is preventing gdb from 'read' accesses on the chr_file nvidiactl.

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

If you believe that gdb should be allowed read access on the nvidiactl 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

Comment 3 Zdenek Pytela 2023-03-30 18:27:14 UTC
It is required to turn this boolean on to allow abrt execute its gdb handler and be able to troubleshoot further:

  # setsebool -P abrt_handle_event on

and subsequently report another bug for the affected component.

This boolean will be turned on by default in the future Fedora releases.
Refer to abrt_handle_event_selinux(8) for more information.
