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.

rmind | branches: 1.20.2;
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.

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.

| 26-Dec-2016 |
rmind | branches: 1.18.14; 1.18.16;
npf_tcp_fsm: fix for the NPF_TCPS_SYN_RECEIVED state.
SYN re-transmission after SYN-ACK was seen by NPF should not terminate
the connection. Thanks to: Alexander Kiselev <kiselev99 at gmail com>
|
| 1.17 |
| 26-Dec-2016 |
christos | 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@)
|
| 1.16 |
| 25-Jul-2014 |
rmind | branches: 1.16.4; 1.16.8;

|
| 1.15 |
| 20-Jul-2014 |
rmind | NPF: add nbuf_t * into npf_cache_t and remove unnecessary carrying by argument.
|
| 1.14 |
| 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.
|
| 1.13 |
| 04-Nov-2013 |
rmind | branches: 1.13.2;
npf_generic_fsm and npf_tcp_fsm: use uint8_t and make the arrays more dense.

- Simplify ICMP ALG a little. While here, handle ICMP ECHO for traceroute.
- Minor fixes, misc cleanup.
|
| 1.11 |
| 06-Oct-2012 |
rmind | npf_tcp_inwindow: inspect the sequence numbers even if the packet contains no
data, fixing up only the RST to the initial SYN. This makes off-path attacks
more difficult. For the reference, see "Reflection Scan: an Off-Path Attack
on TCP" by Jan Wrobel.
|
| 1.10 |

|
| 1.9 |
| 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.
|
| 1.8 |
| 01-Jul-2012 |
rmind | npf_state_tcp: fix for FIN retransmission and out-of-order ACK case.
|
| 1.7 |
| 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.
|
| 1.6 |
| 05-Jun-2012 |
rmind | npf_state_tcp: add an assert; fix some comments while here.
|
| 1.5 |
| 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.
|
| 1.4 |
| 03-Apr-2012 |
rmind | branches: 1.4.2;
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.
|
| 1.3 |
| 08-Dec-2011 |
rmind | branches: 1.3.2;
- Explain the magic in npf_tcpfl2case().
- Use __unused instead of (void)cast; fix comment.
|
| 1.2 |
| 05-Dec-2011 |
rmind | - Add npf_tcpfl2case() and make TCP state table more compact.
- Adjust the state for FIN case on sim-SYN and SYN-RECEIVED.
|
| 1.1 |
| 29-Nov-2011 |
rmind | branches: 1.1.2;
- Rework and improve TCP state tracking.
- Fix regressions after IPv6 patch merge.
Note: npfctl(8) rework will come soon.

- 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.

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.
remove extra rule that got merged...

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.
