I guess Dominic beat me to it. Currently the allow_user booleans do not effect
guest_u or xguest_u, because I want them as locked down as possible.
The question is where to put the threshold
I recently revisited creating a restricted ssh login user from scratch:
https://84.245.5.136/wordpress/create-a-restricted-openssh-login-user-wit...
some stats:
Me (source):
sesearch -ASCT -s myrole_t | grep Found
Found 59 semantic av rules:
Found 4 semantic te rules:
Fedora (source):
sesearch -ASCT -s guest_t | grep Found
Found 620 semantic av rules:
Found 38 semantic te rules:
Found 82 named file transition filename_trans:
me (target):
sesearch -ASCT -t myrole_t | grep Found
Found 30 semantic av rules:
Fedora (target):
sesearch -ASCT -t guest_t | grep Found
Found 909 semantic av rules:
Granted, my policy is probably too locked down as is in many ways. But
it is easier to extend a policy than it is to remove rules from a policy
imho
The way to adjust their policy is through custom policy rules, or you
could
generate a new user type using sepolicy generate (selinux-polgengui)
guest_mysql_u.
