Description Danie de Jager 2019-07-28 17:47:38 UTC
Description of problem:
SELinux is preventing nutdrv_qx from using the 'signal' accesses on a process.

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

If you believe that nutdrv_qx should be allowed signal access on processes labeled unconfined_t 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 'nutdrv_qx' --raw | audit2allow -M my-nutdrvqx
# semodule -X 300 -i my-nutdrvqx.pp
