 1.12  01-Jul-2025  joe Rump testing for layer 2 filtering in NPF

reviewed by christos@
 1.11  23-Jul-2019  rmind NPF improvements:
- Add support for dynamic NETMAP algorithm (stateful net-to-net).
- Add most of the support for the dynamic NAT rules; a little bit more
userland work is needed to finish this up and enable.
- Replace 'stateful-ends' with more permissive 'stateful-all'.
- Add various tunable parameters and document them, see npf-params(7).
- Reduce the memory usage of the connection state table (conndb).
- Portmap rewrite: use memory more efficiently, handle addresses dynamically.
- Bug fix: add splsoftnet()/splx() around the thmap writers and comment.
- npftest: clean up and simplify; fix some memleaks to make ASAN happy.
 1.10  19-Jan-2019  rmind Major NPF improvements:
- Convert NPF connection table to thmap. State lookup is now lock-free.
- Improve connection state G/C: it is now incremental and tunable.
- Add support for dynamic NAT address. Translation addresses can now be
selected from a pool of addresses. There are two selection algorithms,
"ip-hash" and "round-robin" (see the man page).
- Translation address can be specified as e.g. ifaddrs(wm0) in npf.conf
to dynamically choose an IP from the interface address(es).
- Add support for the NETMAP algorithm with static NAT for net-to-net
translation (it is equivalent to iptables NETMAP logic).
- Convert 'ipset' tables to use thmap; the table lookup is now lock-free.
- Misc improvements, bug fixes and more unit tests.
- Bump NPF_VERSION (will also bump libnpf).
 1.9  29-Sep-2018  rmind NPF: Major rework -- migrate NPF to the libnv library.
- This conversion significantly simplifies the code and moves NPF to
a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
previous versions. Also, different serialisation format means NPF
connection/config saving and loading is not compatible with the
previous versions either.

Thanks to christos@ for extra testing.
 1.8  26-Dec-2016  christos branches: 1.8.12; 1.8.14;
Sync NPF with the version on github: backport standalone NPF changes,
which allow us to create and run separate NPF instances. Minor fixes.
(from rmind@)
 1.7  20-Jul-2014  rmind branches: 1.7.4; 1.7.8;
NPF: add nbuf_t * into npf_cache_t and remove unnecessary carrying by argument.
 1.6  25-Jun-2014  rmind Adjust NPF to the recent BPF / BPF JIT changes and make it work again.
All regression tests are happy now (hi alnsn!).
 1.5  24-Jun-2014  alnsn Implement copfuncs and external memory in bpfjit.
 1.4  23-Nov-2013  rmind branches: 1.4.2; 1.4.4;
npftest: adjust for the npf_bpf_filter() change.
 1.3  16-Nov-2013  rmind Enable bpfjit for npftest.
 1.2  08-Nov-2013  rmind NPF: add support for specifying the interfaces before they are attached.
If an interface is or gets detached, all associated rules and connections
will be deactivated (it might be useful to have an option to invalidate
the associated connections). Once the interface is reattached they will
become active.

Bump NPF_VERSION.
 1.1  19-Sep-2013  rmind - Convert NPF to use BPF byte-code by default. Compile BPF byte-code in
npfctl(8) and generate separate marks to describe the filter criteria.
- Rewrite 'npfctl show' functionality and fix some of the bugs.
- npftest: add a test for BPF COP.
- Bump NPF_VERSION.
