Description Dan Callaghan 2017-10-28 04:29:31 UTC
Description of problem:
Using NFSv4 with kerberos (automounted by systemd in case that makes any difference). The AVC denial appeared as soon as I touched something on the NFS filesystem.
SELinux is preventing gssproxy from 'read' accesses on the file unix.

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

If you believe that gssproxy should be allowed read access on the unix file 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 'gssproxy' --raw | audit2allow -M my-gssproxy
# semodule -X 300 -i my-gssproxy.pp
