Running hpacucli from snmpd blocked by SElinux

Hi

I've got RHEL6 server with the targeted SElinux enabled. I'm running a
script /usr/local/sbin/check-hp-smartarray.pl from snmpd. The script
executes and tries to invoke /usr/sbin/hpacucli and that's where the
problems begin.

First of all /usr/sbin/hpacucli runs /opt/compaq/hpacucli/bld/.hpacucli
- that failed because the context of the file was
system_u:object_r:usr_t:s0 - I changed that to bin_t and got a bit
further. Now hpacucli fails because it can't write some temporary files.
Probably because it runs under snmpd_t that isn't allowed to write there.

I don't want to turn off SELinux completely and I don't really agree
with the solutions suggested by audit2allow (essentially it lets snmpd_t
execute everything and write everywhere).

I tried "sudo /usr/sbin/hpacucli" with this sudoers line:

root ALL=(ALL) TYPE=unconfined_t ROLE=unconfined_r NOPASSWD: ALL

but when that is ran from snmpd it fails with "sudo: unable to open
audit system: Permission denied"

Then I tried "runcon root:system_r:unconfined_t:s0-s0:c0.c1023
/usr/bin/hpacucli" and although from the shell it runs fine from snmp
script it fails with:
"runcon: invalid context: root:system_r:unconfined_t:s0-s0:c0.c1023:
Permission denied"

Is there any way to run /usr/sbin/hpacucli as unconfined_t from snmpd or
somehow disable selinux for just that one program?

Thanks!

Michael
