Tested on my local setup but lets see how CI goes. |
opkssh.te only grants permissions to the sshd_t domain, and install-linux.sh always builds/loads the module for sshd_t unconditionally. Some SELinux policies instead run sshd's AuthorizedKeysCommand under sshd_session_t, so on those systems the installed policy denies opkssh the access it needs. install-linux.sh now tries loading the module against sshd_session_t first; if the target's loaded policy doesn't define that type, the load fails and it falls back to the sshd_t module. The choice is based on what the loaded policy actually supports, so it works across distros/versions without hardcoding any of them.
