fix RCSIDs.

Major NPF improvements (merge from upstream):

- Switch to the C11-style atomic primitives using atomic_loadstore(9).

- npfkern: introduce the 'state.key.interface' and 'state.key.direction'
settings. Users can now choose whether the connection state should be
strictly per-interface or global at the configuration level. Keep NAT
logic to be always per-interface, though.

- npfkern: rewrite the G/C worker logic and make it self-tuning.

- npfkern and libnpf: multiple bug fixes; add param exporting; introduce
more parameters. Remove npf_nvlist_{copyin,copyout}() functions and
refactor npfctl_load_nvlist() with others; add npfctl_run_op() to have
a single entry point for operations. Introduce npf_flow_t and clean up
some code.

- npfctl: lots of fixes for the 'npfctl show' logic; make 'npfctl list'
more informative; misc usability improvements and more user-friendly
error messages.

- Amend and improve the manual pages.

Backport selected NPF fixes from the upstream (to be pulled up):

- npf_conndb_lookup: protect the connection lookup with pserialize(9),
instead of incorrectly assuming that the handler always runs at IPL_SOFNET.
Should fix crashes reported on high load (PR/55182).

- npf_config_destroy: handle partially initialized config; fixes crashes
with some invalid configurations.

- NAT policy creation / destruction: set the initial reference and do not
wait for reference draining on destruction; destroy the policy on the
last reference drop instead. Fixes a lockup with the dynamic NAT rules.

- npf_nat_{export,import}: fix a regression since dynamic NAT rules.

- npfctl: fix a regression and restore the default group behaviour.

- Add npf_cache_tcp() and validate the TCP data offset (from maxv@).

PR/54670: Azuma OKAMOTO: Consistently use 'W' for TH_CWN, and bump buffer
size.

npfctl show/validate: fix couple bugs in multiple table/port representation.
Fixes PR/54122.

branches: 1.28.2;
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.

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).

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.

npfctl_build_code: generate TCP/UDP check for ports case when other blocks
do not imply L4 check; add an assert in npfctl_bpf_proto() and elsewhere.

branches: 1.13.2; 1.13.4;
NPF: add support for "stateful-ends".

npfctl_print_nat: fix the byte-order of the port.

npfctl_print_table: add a "cdb" type.

NPF:
- Adjust the syntax - remove "inet" keyword in favour of more explicit
"inet4" for the address family. Consistent with "inet6" for IPv6.
- Adjust and improve the man page a little bit.

NPF: add support for static (stateless) NAT.

npfctl: need to rewind the list after calling print_table(). XXX libnpf.

Add npf_tableset_syncdict() to sync the table IDs in the proplib dictionary,
as they can change on reload now. Also, fix table name checking in npfctl.

CID 1129614: dereference after null

Simplify parsing of npf.conf elements, create the npfvar_t when a value is
parsed (to be used as a general structured for variables and inlined values),
few misc improvements.

NPF: add support for table naming and remove NPF_TABLE_SLOTS (there is
just an arbitrary sanity limit of NPF_MAX_TABLES currently set to 128).

Few misc fixes. Bump NPF_VERSION.

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.

- NPF: change the group/ruleset syntax - simplify. Update npf.conf(5) manual.
- Add support for the inline pcap-filter(7) syntax in the rule, e.g.:
block out final pcap-filter "tcp and dst 10.1.1.252"

- 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.

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.

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).

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.

branches: 1.25.2; 1.25.4;
npfctl: add support for the 'no-ports' flag in the 'map' statements.
This allows us to create a NAT policy without the port translation.

Always print the rule id associated with a rule.

Sync NPF with the version on github: backport standalone NPF changes,
which allow us to create and run separate NPF instances. Minor fixes.
