 1.23  30-May-2020  rmind 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.
 1.22  23-Jul-2019  rmind branches: 1.22.2;
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.
 1.21  29-Oct-2018  christos We need to have rump tests work in two modes:

1. npf unit tests. In this case only the npf subsystem is created
and dictionaries are passed directly.
2. kernel system tests (like the ipsec natt test). In this case, npf is
instantiated regularly as part of the kernel and dictionaries are
passed via ioctl.

We differentiate between the two cases by checking the "mbufops" member
which is NULL, regularly and non-NULL in the npf unit tests. Previously
this was done using an ifdef which obviously can't work for both cases.
 1.20  26-Oct-2018  christos enable the sampling function for _NPF_RUMP
 1.19  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.
 1.18  26-Dec-2016  christos branches: 1.18.14; 1.18.16;
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@)
 1.17  20-Jul-2014  rmind branches: 1.17.4; 1.17.8;
NPF: add nbuf_t * into npf_cache_t and remove unnecessary carrying by argument.
 1.16  19-Jul-2014  rmind NPF: partially rewrite the connection tracking mechanism:
- Separate the tracking interface from the storage (state table)
and thus prepare to use a new data structure for the storage.
- Fix some race conditions in NAT association logic.
 1.15  04-Nov-2013  rmind branches: 1.15.2;
npf_generic_fsm and npf_tcp_fsm: use uint8_t and make the arrays more dense.
 1.14  09-Feb-2013  rmind branches: 1.14.2;
NPF:
- Implement dynamic NPF rules. Controlled through npf(3) library of via
npfctl rule command. A rule can be removed using a unique identifier,
returned on addition, or using a key which is SHA1 hash of the rule.
Adjust npftest and add a regression test.
- Improvements to rule inspection mechanism.
- Initial BPF support as an alternative to n-code.
- Minor fixes; bump the version.
 1.13  24-Dec-2012  rmind - Rework NPF's nbuf interface: use advancing and ensuring as a main method.
Eliminate unnecessary copy and simplify. Adapt regression tests.
- Simplify ICMP ALG a little. While here, handle ICMP ECHO for traceroute.
- Minor fixes, misc cleanup.
 1.12  15-Aug-2012  rmind branches: 1.12.2;
Add npf_state_setsampler() for _NPF_TESTING case. This also fixes the build.
 1.11  12-Aug-2012  rmind - Extend npftest: add ruleset inspection testing from the config generated
by npfctl debug functionality. Auto-create npftest interfaces for this.
- NPF sessions: combine protocol and interface into a separate substructure,
share between the entries and thus fix the handling of them. Constify.
- npftest: add regression tests for NAT policies.
- npf_build_nat: simplify and fix bi-NAT regression.
- Bump yacc stack size for npfctl.
 1.10  21-Jul-2012  rmind - npf_fetch_tcpopts: fix off-by-one when validating TCP option length
against the maximum allowed.
- npf_tcp_inwindow: be more liberal with npf_fetch_tcpopts().
- Few minor improvements to npftest.
 1.9  01-Jul-2012  rmind NPF improvements:
- Add NPF_OPCODE_PROTO to match the address and/or protocol only.
- Update parser to support arbitrary "pass proto <name/number>".
- Fix IPv6 address and protocol handling (add a regression test).
- Fix few theorethical races in session handling module.
- Misc fixes, simplifications and some clean up.
 1.8  22-Jun-2012  rmind NPF:
- Rename some functions for consistency and de-inline them.
- Fix few invalid asserts (add regressoin test).
- Use pserialize(9) for ALG interface.
- Minor fixes, sprinkle many comments.
 1.7  30-May-2012  rmind npftest: add a stream processor, which prints out the TCP state information.
A tool for debugging connection tracking from tcpdump -w captured data.
 1.6  29-Nov-2011  rmind branches: 1.6.2; 1.6.4;
- Rework and improve TCP state tracking.
- Fix regressions after IPv6 patch merge.

 1.4  25-Apr-2011  yamt branches: 1.4.4;
fix module build
 1.3  18-Jan-2011  rmind branches: 1.3.4;
NPF checkpoint:
- Add the concept of rule procedure: separate normalization, logging and
potentially other functions from the rule structure. Rule procedure can be
shared amongst the rules. Separation is both at kernel level (npf_rproc_t)
and configuration ("procedure" + "apply").
- Fix portmap sharing for NAT policy.
- Update TCP state tracking logic. Use TCP FSM definitions.
- Add if_byindex(), OK by matt@. Use in logging for the lookup.
- Fix traceroute ALG and many other bugs; misc clean-up.
 1.2  18-Dec-2010  rmind branches: 1.2.2;
NPF checkpoint:
- Add support for session saving/restoring.
- Add packet logging support (can tcpdump a pseudo-interface).
- Support reload without flushing of sessions; rework some locking.
- Revisit session mangement, replace linking with npf_sentry_t entries.
- Add some counters for statistics, using percpu(9).
- Add IP_DF flag cleansing.
- Fix various bugs; misc clean-up.
 1.1  11-Nov-2010  rmind NPF checkpoint:
- Add proper TCP state tracking as described in Guido van Rooij paper,
plus handle TCP Window Scaling option.
- Completely rework npf_cache_t, reduce granularity, simplify code.
- Add npf_addr_t as an abstraction, amend session handling code, as well
as NAT code et al, to use it. Now design is prepared for IPv6 support.
- Handle IPv4 fragments i.e. perform packet reassembly.
- Add support for IPv4 ID randomization and minimum TTL enforcement.
- Add support for TCP MSS "clamping".
- Random bits for IPv6. Various fixes and clean-up.

Eliminate unnecessary copy and simplify. Adapt regression tests.
- Simplify ICMP ALG a little. While here, handle ICMP ECHO for traceroute.
- Minor fixes, misc cleanup.
Silence gcc in npf_recache().
Add m_ensure_contig() routine, which is equivalent to m_pullup, but does not
destroy the mbuf chain on failure (it is kept valid).
- nbuf_ensure_contig: rework to use m_ensure_contig(9), which will not free
the mbuf chain on failure. Fixes some corner cases. Improve regression
test and sprinkle some asserts.
- npf_reassembly: clear nbuf on IPv6 reassembly failure path (partial fix).
The problem was found and fix provided by Anthony Mallet.

Move and rename librumpdev_npf to librumpnet_npf.
Enable the build of librumpnet_npf.
Add npf_state_setsampler() for _NPF_TESTING case. This also fixes the build.
Call pserialize_init() during rump start-up, since librump/net/npf
uses it.
It helps to include the declaration of the routine being called.
We also need kcpuset_init() now.
Use correct routine name - kcpuset_sysinit() vs kcpuset_init()

npf_tcp_inwindow: in a case of negative skew, bump the maximum seen value of
SEQ+LEN in the receiver's side correctly (using ACK from the sender's side).
PR/46265 from Changli Gao.
rumpnet_net: add pfil.c
Update rumpdev_npf; use WARNS=4.
Add initial NPF regression tests integrated with RUMP framework (running the
kernel part of NPF in userland). Other tests will be added once converted to
RUMP framework. All tests are in the public domain.
Some Makefile fixes from christos@.
- Fix double-free case on ICMP return case.
- npf_pfil_register: handle kernels without INET6 option correctly.
- Reduce some #ifdefs.
npfctl(8): add show-config command. Also, update syntax.
npftest: add a stream processor, which prints out the TCP state information.
A tool for debugging connection tracking from tcpdump -w captured data.
npftest: add a module for TCP state tracking and add few test cases.
npf_state_tcp: add an assert; fix some comments while here.
- Rework NPF NAT syntax to be more structured and support future additions
of different types and configurations of NAT.
- npfctl: improve disassemble and show-config command functionality.
- Fix custom ICMP code and type filtering.
make this compile again.
remove error(1) output
Remove superfluous Pp
- make each element of a variable hold a type
- change get_type to take an index, so we can get the individual types of
each element (since primitive elements can be in lists)
- make port_range primitive
- add a routine to convert a variable of primitives to a variable containing
- only port ranges.

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.

npf_worker_sys{init,fini}: initialize/destroy the exit_cv condvar.

npftest -- npf_test_init(): add a workaround for NetBSD.

npf-params(7): fix the state.key defaults.

npf-params.7: s/filer/filter/

Adjust to "npfctl debug" command line changes, from rmind@.

Use more markup.
