Description Niki Guldbrand 2013-04-20 12:26:42 UTC
SELinux is preventing /usr/sbin/gpsd from using the sys_ptrace capability.

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

If you believe that gpsd should have the sys_ptrace capability 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 gpsd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Niki Guldbrand 2013-04-20 12:28:34 UTC
Disabled some of my old custom fixes to the policy, and this one shows up when I restart gpsd via systemctl

Comment 2 Daniel Walsh 2013-04-21 11:41:24 UTC
b93d96bbd97dd86c9a9956c06ae23c23c963867b adds a dontaudit in git.

I don't think gpsd actually needs this access.
