 1.12 01-Jun-2025  joe testing for NPF user/group filtering: reviewed by christos@
 1.11 30-May-2020  rmind branches: 1.11.8;
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.

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.

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.

reviewed by christos@
 1.11 23-Jul-2019  rmind branches: 1.11.12;
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.

"ip-hash" and "round-robin" (see the man page).

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.

 1.4 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.
 1.3 11-Aug-2019  rmind Adjust some internal NPF APIs:

connection/config saving and loading is not compatible with the
previous versions either.

- 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.
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.

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.

 1.13 11-Aug-2019  rmind Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.
 1.12 23-Jul-2019  rmind branches: 1.12.2;
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.
 1.11 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).

as per RFC 6296. Add a unit test. Also, bump NPF_VERSION.

Thanks to S.P.Zeidler for the help with NPTv6 work!
 1.7 07-Feb-2014  rmind NPF: add support for static (stateless) NAT.
 1.6 05-Feb-2014  rmind npftest: fix previous harder - pass and use libc's random(3).
 1.5 05-Feb-2014  rmind npftest: fix the failure of NAT test -- adjust for RUMP's conversion to
the in-kernel CPRNG (hi pooka!).
 1.4 24-Sep-2013  rmind npftest: add some concurrency testing code.
 1.3 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.
 1.2 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.

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.

npf-params(7): add more bpf.jit details.
From David H. Gutteridge.

Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.

npf.7: add xref to npf-params.7
(Adding directly here since this particular file isn't included in
rmind@'s upstream GitHub repo at present.)
 1.10 21-Aug-2019  rmind - npftest: fix a memleak in a unit test (standalone path only).
- Minor style fixes. No functional change.
 1.9 25-Jul-2019  rmind branches: 1.9.2;
npftest: fix double-free in npf_nbuf_test().
 1.8 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.
 1.7 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).
 1.6 26-Dec-2016  christos branches: 1.6.12; 1.6.14;
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@)
 1.5 08-Nov-2013  rmind branches: 1.5.8;
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.
 1.4 20-Jan-2013  rmind - 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.
 1.3 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.
 1.2 21-Aug-2012  rmind branches: 1.2.2;
npftest:
- Do not stop running other tests, if some tests fail.
- Fix some endianness bugs in the test cases.

Tested on sparc64 by martin@, all tests pass.
 1.1 14-Apr-2012  rmind branches: 1.1.2; 1.1.4;
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@.

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.

- npftest: fix a memleak in a unit test (standalone path only).
- Minor style fixes. No functional change.
npfkern/libnpf: Add support for the table replace/swap operation.
Contributed by Timshel Knoll-Miller.
 1.9 11-Aug-2019  rmind Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.
 1.8 23-Jul-2019  rmind branches: 1.8.2;
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.
 1.7 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).
 1.6 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.
 1.5 26-Dec-2016  christos branches: 1.5.12; 1.5.14;
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@)
 1.4 25-Jun-2014  rmind branches: 1.4.4; 1.4.8;
npftest: add an example in the README, fix the total in npf_test_conc().
 1.3 24-Sep-2013  joerg branches: 1.3.2; 1.3.4;
Add missing dead.
 1.2 24-Sep-2013  rmind npftest: add a choice of "rule" or "state" for -b option.
 1.1 24-Sep-2013  rmind npftest: add some concurrency testing code.

- 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.
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.

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.

when extracting variables for filtering in NPF, allow the handler to
recursively extract all variables that might be present in the parent variable
to fully get all the filter elements present in them. this issue poses a security risk
as intruders can find their way into your machine if you intend to block them
but have their IPs in a nested variable with other IPs as well.

so this needs to be pulled up to 9, 10, 11

PR bin/55403: npfctl miscompiles IPv6 rules
 1.19 25-Aug-2019  rmind branches: 1.19.8; 1.19.10;
- npfctl_load_nvlist: simplify the config loading logic.
- Fix a small race condition in npf_nat_getaddr().
- Rework pserialize/EBR wrappers, make it easier to maintain.
 1.18 11-Aug-2019  rmind Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.
 1.17 23-Jul-2019  rmind branches: 1.17.2;
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.
 1.16 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).
 1.15 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.

 1.11 01-Jul-2025  joe Rump testing for layer 2 filtering in NPF

reviewed by christos@
 1.10 30-May-2020  rmind branches: 1.10.8;
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.
 1.9 23-Jul-2019  rmind branches: 1.9.2;
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.
 1.8 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).
 1.7 26-Dec-2016  christos branches: 1.7.12; 1.7.14;
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@)
 1.6 20-Jul-2014  rmind branches: 1.6.6;
NPF: add nbuf_t * into npf_cache_t and remove unnecessary carrying by argument.
 1.5 08-Nov-2013  rmind branches: 1.5.2;
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.
 1.4 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.
 1.3 21-Aug-2012  rmind branches: 1.3.2; 1.3.4;
npftest:
- Do not stop running other tests, if some tests fail.
- Fix some endianness bugs in the test cases.

Tested on sparc64 by martin@, all tests pass.
 1.2 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.
 1.1 04-Jun-2012  rmind branches: 1.1.2;

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.

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.
 1.10.8.1 02-Aug-2025  perseant Sync with HEAD
 1.12 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.
 1.11 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).
 1.10 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.
 1.9 26-Dec-2016  christos branches: 1.9.12; 1.9.14;
Sync NPF with the version on github: backport standalone NPF changes,

 1.4 15-Jul-2012  rmind - Rework NPF tables and fix support for IPv6. Implement tree table type
using radix / Patricia tree. Universal IPv4/IPv6 comparator for ptree(3)
was contributed by Matt Thomas.
- NPF tables: update regression tests, improve npfctl(8) error messages.
- Fix few bugs when using kernel modules and handle module autounloader.
- Few other fixes and misc cleanups.
- Bump the version.
 1.3 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.
 1.2 22-Jun-2012  rmind branches: 1.2.2;
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.

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.

 1.21 30-May-2020  rmind branches: 1.21.8;
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.

 1.19 23-Jul-2019  rmind branches: 1.19.2;
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.
 1.18 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).
 1.17 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.

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.

Add npf_state_setsampler() for _NPF_TESTING case. This also fixes the build.
Call pserialize_init() during rump start-up, since librump/net/npf

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 portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.
 1.15 23-Jul-2019  rmind branches: 1.15.2;
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.
 1.14 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).
 1.13 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.
 1.12 26-Dec-2016  christos branches: 1.12.12; 1.12.14;
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@)
 1.11 10-Aug-2014  tls branches: 1.11.6;
Merge tls-earlyentropy branch into HEAD.
 1.10 23-Jul-2014  rmind NPF: rework of the connection saving and restoring:
- Add support for saving a snapshot of the current connections together
with a full configuration. Support a reverse load operation. Eliminate
the old 'sess-save' and 'sess-load' in favour of the new mechanism.
- Share code between load and reload operations: the latter performs
load from npf.conf without affecting the connections.
- Simplify and fix races with connection loading.
- Bump NPF_VERSION.
 1.9 13-Feb-2014  rmind branches: 1.9.2;
NPF: add support for IPv6-to-IPv6 Network Prefix Translation (NPTv6),
as per RFC 6296. Add a unit test. Also, bump NPF_VERSION.

Thanks to S.P.Zeidler for the help with NPTv6 work!
 1.8 05-Feb-2014  rmind npftest: fix previous harder - pass and use libc's random(3).
 1.7 05-Feb-2014  rmind npftest: fix the failure of NAT test -- adjust for RUMP's conversion to
the in-kernel CPRNG (hi pooka!).
 1.6 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.
 1.5 24-Sep-2013  rmind npftest: add some concurrency testing code.
 1.4 15-Aug-2012  rmind branches: 1.4.2; 1.4.4;

Call pserialize_init() during rump start-up, since librump/net/npf

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.

npf-params(7): add more bpf.jit details.
From David H. Gutteridge.

Adjust some internal NPF APIs:
* npfkern: use the npfk_ prefix.
* NPF portmap: amend the API so it could be used elsewhere.
* Make npf_connkey_t public.

npf.7: add xref to npf-params.7
