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 > diff --git a/python/sepolicy/sepolicy-bash-completion.sh b/python/sepolicy/sepolicy-bash-completion.sh > index 13638e4d..467333b8 100644 > --- a/python/sepolicy/sepolicy-bash-completion.sh > +++ b/python/sepolicy/sepolicy-bash-completion.sh > @@ -52,7 +52,7 @@ __get_all_classes () { > seinfo -c 2> /dev/null | tail -n +2 > } > __get_all_port_types () { > - seinfo -aport_type -x 2> /dev/null | tail -n +2 > + sepolicy network -l > } > __get_all_domain_types () { > seinfo -adomain -x 2> /dev/null | tail -n +2 > diff --git a/python/sepolicy/sepolicy/__init__.py b/python/sepolicy/sepolicy/__init__.py > index c177cdfc..9d3b640b 100644 > --- a/python/sepolicy/sepolicy/__init__.py > +++ b/python/sepolicy/sepolicy/__init__.py > @@ -989,7 +989,7 @@ def get_all_port_types(): > global port_types > if port_types: > return port_types > - port_types = list(sorted(info(ATTRIBUTE, "port_type"))[0]["types"]) > + port_types = [x["type"] for x in info(PORT)] > return port_types > > > -- > 2.39.2
