Sometimes it's necessary to configure SELinux before it's enabled on the
system. There's `ignore_selinux_state` which should allow it. Before
this change `seboolean` module failed on SELinux disabled system even
with `ignore_selinux_state: true` and SELinux policy installed while
`semanage boolean` worked as expected:
$ ansible -i 192.168.121.153, -m seboolean -a "name=ssh_sysadm_login state=on ignore_selinux_state=true" all
192.168.121.153 | FAILED! => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python3"
},
"changed": false,
"msg": "Failed to get list of boolean names"
}
$ ssh root@192.168.121.153 semanage boolean -l | grep ssh_sysadm_login
ssh_sysadm_login (off , off) Allow ssh to sysadm login
It's caused by `selinux.security_get_boolean_names()` and
`selinux.security_get_boolean_active(name)` which required SELinux
enabled system.
This change adds a fallback to semanage API which works in SELinux
disabled system when SELinux targeted policy is installed:
ANSIBLE_LIBRARY=plugins/modules ansible -i 192.168.121.153, -m seboolean -a "name=ssh_sysadm_login state=on persistent=true ignore_selinux_state=true" all
192.168.121.153 | CHANGED => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python3"
},
"changed": true,
"name": "ssh_sysadm_login",
"persistent": true,
"state": true
}
$ ssh root@192.168.121.153 semanage boolean -l | grep ssh_sysadm_login
ssh_sysadm_login (on , on) Allow ssh to sysadm login
Note that without `persistent=true` this module is effectively NO-OP now.

In modern systems (RHEL8+) with python3 default the library requirement is `python3-libsemanage`.
Updated `libsemanage-python` to `python3-libsemanage`.
