I would probably label /usr/local/snmp/bin/ and anything below type
bin_t. This will atleast stop snmpd_t from executing generic usr files.
Example;
semanage fcontext -a -t bin_t "/usr/local/snmp/bin(/.*)?"
restorecon -R -v /usr/local/snmp/bin
Besides that i guess you would need to allow snmpd_t to
read /proc/mdstat files but you can use audit2allow for that as you did
below.
Thanks, I like it. My snmpScripts.te looks simpler now:
module snmpScripts 1.0;
require {
type snmpd_t;
type proc_mdstat_t;
class file { read ioctl open getattr };
}
#============= snmpd_t ==============
allow snmpd_t proc_mdstat_t:file { read ioctl open getattr };
I notice that I failed to include all of my previous snmpScripts.te. Two allow lines at
the bottom were missing - one for usr_t as you mentioned above and the one shown here for
proc_mdstat_t.
