Currently the packet class in SELinux is not checked if there are no
SECMARK rules in the security or mangle netfilter tables. Similarly, the
peer class is not checked if there is no NetLabel or labeled IPSEC. Some
systems prefer that these classes are always checked, for example, to
protect the system should the netfilter rules fail to load or if the
nefilter rules were maliciously flushed.
Add the always_check_network policy capability which, when enabled, treats
these mechanisms as enabled, even if there are no labeling rules.
