Yes strict no longer exists, so remove any reference to it

You policy should have no require{} in the .te file, everything should
have an api that you can use instead
Only type transition on what you need to type transition on, instead of
everything (you type transition on everything)
corecmd_bin_entry_type(gogoc_t) <- this doesnt make sense as you do not
domain type transition on bin_t anywhere
radvd_admin(gogoc_t, system_r) <- this one isnt appropriate here
systemd_exec_systemctl(gogoc_t) <- why is this needed?
allow gogoc_t radvd_exec_t:file { read execute open execute_no_trans };
<-- depending on why gogoc runs dadvd you may want to run radvd with a
domain transition instead. If it turns out that you should have ran
radvd with a domain transition ,then it is encouraged you start over
with your policy because, one should always take care of type
transitions first before adding any other rules. because type
transitions can greatly impact access your process needs
There are duplicate rules in your policy
For example:
sysnet_dns_name_resolve(gogoc_t)
and
files_read_etc_files(gogoc_t)
are already enclosed with:
auth_use_nsswitch(gogoc_t)
Theres probably a bit moreroom for improvement other than above but this
is a start
