Fwd: [Bug 2170630] New: SELinux is preventing zabbix_agentd from 'getattr' accesses on the file /proc/kcore.

[Orion Poplawski]

I would really appreciate some SELinux expertise with this issue.  There 
is a little more discussion in the report.

Thanks,

Orion

Description of problem:
SELinux is preventing zabbix_agentd from 'getattr' accesses on the file
/proc/kcore.

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

If you believe that zabbix_agentd should be allowed getattr access on 
the kcore
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 'zabbix_agentd' --raw | audit2allow -M my-zabbixagentd
# semodule -X 300 -i my-zabbixagentd.pp
