Description Rob Riggs 2019-06-21 03:23:28 UTC
Description of problem:
This happens frequently when using RFCOMM devices from Python.  I do not know the exact cause of the problem.
SELinux is preventing ps from 'search' accesses on the directory 31981.

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

If you believe that ps should be allowed search access on the 31981 directory 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 'ps' --raw | audit2allow -M my-ps
# semodule -X 300 -i my-ps.pp

Something is blueman is running a 'ps' process that is prevented from from accessing /proc entries.  This is causing AVC denials -- hundreds of them -- frequently when using the Bluetooth RFCOMM from Python.
