 1.63  20-Aug-2025  joe enclose NPF_VAR_ID case in braces to fix linter build
 1.62  20-Aug-2025  joe PR bin/59511

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


this fix has been reviewed by christos@ and martin@ and tests have been included.
 1.61  12-Aug-2025  mlelstv pcap rules don't pass filter options. Provide default filter opts
(layer 3 for compat with previous behaviour) to prevent npfctl from
crashing.
 1.60  12-Aug-2025  joe PR bin/59581

set layer bit in dynamic rule attributes
effectively use it when listing either layer 2 or 3 rules

This fixes it

npfctl: adapt to new libpcap API
 1.55  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.
 1.54  23-May-2020  rmind 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@).
 1.53  30-Sep-2019  rmind libnpf/npfctl: support dynamic NAT rulesets using a name prefix.

 1.50  25-Jul-2019  rmind branches: 1.50.2;
npfctl: fix the bpf.jit parameter handling.
 1.49  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.
 1.48  17-Apr-2019  tih Summary: Ensure default TCP flags are applied to rules like 'pass stateful all'

The documented default "flags S/SAFR" for stateful rules that affect
TCP packets but don't specify any flags, doesn't actually get applied
to a rule like "pass stateful out all". The big problem with this is
that when you then do a "block return-rst" for an incoming packet, the
generated RST packet will create state for the connection attempt it's
blocking, so that a second attempt from the same source will pass.

This change makes the default flags actually apply to such simple
rules. It also fixes a related bug in the code generation for the
flag matching, where part of the action could erroneously be omitted.

 1.47  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).
 1.46  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.

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.
 1.37  15-May-2014  rmind NPF: imply SYN-only check for the stateful rules by default (when inspecting
TCP packets). Many users trip here. This behaviour can be overriden with the
explicit "flags" keyword, but other configuration does not really make sense.

of different types and configurations of NAT.
- npfctl: improve disassemble and show-config command functionality.
- Fix custom ICMP code and type filtering.
 1.6  26-Feb-2012  christos branches: 1.6.2;
- 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.
 1.5  20-Feb-2012  rmind - Add NPF_DECISION_BLOCK and NPF_DECISION_PASS. Be more defensive in the
packet handler. Change the default policy to block when the config is
loaded and set it to pass when flush operation is performed.
- Use kmem_zalloc(9) instead of kmem_alloc(9) in few places.
- npf_rproc_{create,release}: use kmem_intr_{alloc,free} as the destruction
of rule procedure might happen in the interrupt handler (under a very rare
condition, if config reload races with the handler).

asserts, bump the version.
 1.2  15-Jan-2012  rmind - Expire all sessions on flush.
- Enable checking for zero mask in IP{4,6}MATCH after npfctl changes.

- Sync function prototypes in npf(3) man page with reality.
- Rename NPF_TABLE_RBTREE to NPF_TABLE_TREE.
 1.1  08-Jan-2012  rmind Full rewrite of npfctl(8) parser and rework of n-code generation part.
Fixes most of the known bugs and issues with the utility. Note: rule
procedures are not yet (as we want to make them fully modular).

Huge thanks to Martin Husemann who wrote the parser and Christos Zoulas
who wrote intermediate structures and helped to complete the work.

Implement dynamic NPF extensions interface. An extension consists of
dynamically loaded module (.so) supplementing npfctl(8) and a kernel
module. Move normalisation and logging functionality into their own
extensions. More improvements to come.
Add /usr/lib/npf.
Add ./usr/libdata/debug/usr/lib/npf for rmind
Fix MKDEBUG set lists
ext_ops does not change during the life cycle and can be fetched without
the mutex held. This avoids confusion in the compiler about an uninitialized
variable ext_ops.

- 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.

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.

- Add NPF_DECISION_BLOCK and NPF_DECISION_PASS. Be more defensive in the
packet handler. Change the default policy to block when the config is
loaded and set it to pass when flush operation is performed.
- Use kmem_zalloc(9) instead of kmem_alloc(9) in few places.
- npf_rproc_{create,release}: use kmem_intr_{alloc,free} as the destruction
of rule procedure might happen in the interrupt handler (under a very rare
condition, if config reload races with the handler).
- npf_session_establish: check whether layer 3 and 4 are cached.
- npfctl_build_group: do not make groups as passing rules.
- Remove some unecessary header inclusion.
Simplify slightly: merge iface into addr_or_iface, use it in filt_addr.
Add a small disassembler.

- better printing of type/code flags/mask
- pass the instruction start pointer, instead of subtracting 1 to account for it
- Save active config in proplib dictionary; add GETCONF ioctl to retrieve.

NPF: replace the TAILQ of the dynamic rules with a linked list and fix the
inheriting of the active dynamic rules during the reload; also, fix a bug
in the insert path by putting a memory barrier in the right place.

- Fix the filter criteria when to/from is omitted but port used.
- Print more user-friendly error if an NPF table has a duplicate entry.

Summary: Ensure default TCP flags are applied to rules like 'pass stateful all'

The documented default "flags S/SAFR" for stateful rules that affect
TCP packets but don't specify any flags, doesn't actually get applied
to a rule like "pass stateful out all". The big problem with this is
that when you then do a "block return-rst" for an incoming packet, the
generated RST packet will create state for the connection attempt it's
blocking, so that a second attempt from the same source will pass.

This change makes the default flags actually apply to such simple
rules. It also fixes a related bug in the code generation for the
flag matching, where part of the action could erroneously be omitted.

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.

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@).
