Description Lukas Slebodnik 2015-04-18 11:21:25 UTC
Description of problem:
systemctl start dnssec-triggerd
SELinux is preventing /usr/bin/python3.4 from 'search' accesses on the directory .local.

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

If you believe that python3.4 should be allowed search access on the .local 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:
# grep dnssec-trigger- /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Lukas Slebodnik 2015-04-18 11:22:23 UTC
I could not see AVC in permissive mode.

Comment 2 Lukas Slebodnik 2015-04-18 12:06:33 UTC
What does dnssec-triggerd want to do /root/.local?
Could you use different directory? /var/lib/dnssec-trigger/ ...

Comment 3 Miroslav Grepl 2015-04-27 17:06:00 UTC
This is caused by python. The following should be added

-E     Ignore environment variables like PYTHONPATH and PYTHONHOME that modify
the behavior of the interpreter.

- s     Don't add user site directory to sys.path.

Thank you for the clue.
