Looks like some changes were made in the policy:
rhel72# sesearch -s cockpit_session_t -t cockpit_session_t -c process -A
Found 4 semantic av rules:
allow cockpit_session_t cockpit_session_t : process { fork sigchld sigkill sigstop signull signal getsched setsched getsession getcap getattr setexec setrlimit setkeycreate } ;
allow login_pgm domain : process sigkill ;
allow cockpit_session_t cockpit_session_t : process setfscreate ;
allow cockpit_session_t cockpit_session_t : process setfscreate ;
rhel73# sesearch -s cockpit_session_t -t cockpit_session_t -c process -A
Found 4 semantic av rules:
allow login_pgm domain : process sigkill ;
allow cockpit_session_t cockpit_session_t : process { fork sigchld sigkill sigstop signull signal getsched setsched getcap setexec setkeycreate } ;
allow cockpit_session_t cockpit_session_t : process setfscreate ;
allow cockpit_session_t cockpit_session_t : process setfscreate ;
f22 and f25 looks the same like rhel73
