It looked good to me but I was getting different number of types when I
searched for `port_type` attribute method and for `portcon` (seinfo
--portcon).
So I compared lists and checked differences and it turned out that this
would break using `semanage port -a ...` for all policies based on
refpolicy.
In refpolicy there are types with `port_type` attribute but without any
`portcon` statement, see this commit
https://github.com/SELinuxProject/refpolicy/commit/a108d9db60747a887f626b99cce37738462dd3cd
SELinux notebook uses `port_type` attribute too -
https://github.com/SELinuxProject/selinux-notebook/blob/main/src/network_support.md#socket-controls-access-control-for-network-ports
I.e. using this change it would not be possible to add a new port mapping for
types like `stunnel_port_t`:
# seinfo -aport_type -x | grep stunnel
stunnel_port_t
# semanage port -a -t stunnel_port_t -p tcp 12345
ValueError: Type stunnel_port_t is invalid, must be a port type
Thanks,
Petr
