Description of problem: Base policy contains no file context is defined for /var/agentx/master unix domain socket. This is the default socket for establishing master<->subagent communications. Version-Release number of selected component (if applicable): net-snmp-5.3.1-24.el5 selinux-policy-targeted-2.4.6-137.el5 How reproducible: Steps to Reproduce: Method A: 1. disable SELinux 2. Configure snmpd with subagents. 3. Verify snmpd is working correctly 4. change SELinux enforcement to "enforcing" 5. reboot to put changes into effect. 6. Note SELinux exception. Method B: 1. Configure snmpd with subagents 2. service snmpd stop 3. restorecon -r /var/agentx 4. service snmpd start 5. Note SELinux exception. Actual results: Relabeling places a var_t label on /var/agentx/master snmpd is prevented from communicating with its subagents Expected results: Relabeling places a snmpd_var_lib_t label on /var/agentx/master Additional info:
There must be something wrong in the policy - snmpd creates /var/agentx/master correctly with user_u:object_r:snmpd_var_lib_t context, but restorecon sets it to 'system_u:object_r:var_t', which is wrong.
Adding /var/agentx(/.*)? gen_context(system_u:object_r:snmpd_var_lib_t,s0) To File Context Fixed in selinux-policy-2.4.6-157
