If you label the dir as audisp_var_run_t then this should work nicely with SELinux
# semanage fcontext -a -t audisp_var_run_t /var/run/xxx
# restorecon -Rv /var/run/xxx
The plugin should have its own policy. I don't think audisp_t
should be
broadened to allow things it shouldn't be doing. There are probably several
people on this list that can give you advice on creating a policy.
