Description Mikhail 2022-07-05 05:06:00 UTC
Description of problem:
clinfo is crashed
SELinux is preventing gdb from 'read' accesses on the chr_file kfd.

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

If you believe that gdb should be allowed read access on the kfd 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 1 Zdenek Pytela 2022-07-07 11:13:11 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.

Refer to abrt_handle_event_selinux(8) for more information.
