avc for gpsd and ntpd use of shm

[Skunk Worx]

Sup,

I am using EPEL 6 and a garmin 18 LVC on a serial port with gpsd. I am 
fairly new to the selinux environment.

ntpd is supposed to be able to access a couple of shm locations to get 
time from the gps daemon.

In /var/log/messages I see :

Mar 18 00:10:11 localhost ntpd[8899]: SHM shmget (unit 0): Permission denied
Mar 18 00:10:11 localhost ntpd[8899]: configuration of 127.127.28.0 failed
Mar 18 00:10:11 localhost ntpd[8899]: SHM shmget (unit 1): Permission denied
Mar 18 00:10:11 localhost ntpd[8899]: configuration of 127.127.28.1 failed

Also avc messages :

Here's some direction from audit2allow :

# grep ntpd /var/log/audit/audit.log | audit2allow
#============= ntpd_t ==============
allow ntpd_t unconfined_t:shm { unix_read unix_write };

Should I use audit2allow and create a policy package to fix this or is 
there a better way?

Thanks,
John
