compiler for PF does not need to generate protocol match "proto {tcp
udp icmp}" when service object used in the NAT rule is "any". The
reason this was done this way is lost in the mist of time; it's been
like this since very early versions of fwbuilder.
should use "(interface)" syntax to the right of "->" in NAT rules.
This now works for all interfaces, including those that have ip
addresses in fwbuilder configuration, when interface object appears in
"Translated Source" in a nat rule. When firewall object appears in
"Translated Source", it gets replaced with a set of its interfaces
which also get translated into "-> (interface)".
single object negation in "Inbound Interface" and "Outbound
Interface" columns in compiler for iptables.
* NATCompiler_pf.cpp (compile): see #2456 Added support for single
object negation in "Interface" rule element of PF NAT rules. Now
compiler can produce PF commands such as "nat on ! em0 ... " (for
PF <4.7) or "match on ! em0 ..." (for PF >= 4.7)
* Compiler.cpp (singleObjectNegation::processNext): moved rule
processor that processes single object negation in any rule
element to the base class Compiler.
rule element by name after group is expanded, this helps ensure
stable ordering of objects in generated configuration.
* Compiler.cpp (replaceClusterInterfaceInItfRE::processNext):
sorting objects in rule element after cluster interfaces have been
replaced, this helps ensure stable ordering of objects in generated
configuration.
* FWObject.h (FWObjectNameCmpPredicate): moved this class from
gui-specific module to libfwbuilder as it is universally useful.
It can compare FWObject objects by name and can optionally can
follow references; it can be used with std::sort() to sort lists
of FWObject pointers or directly sort rule elements.
