- 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.
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.
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.
- 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.
dynamically loaded module (.so) supplementing npfctl(8) and a kernel
module. Move normalisation and logging functionality into their own
extensions. More improvements to come.
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.
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.
- 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.
- Enable checking for zero mask in IP{4,6}MATCH after npfctl changes.
- Make locking symmetric for npf_ruleset_inspect().
- Sync function prototypes in npf(3) man page with reality.
- Rename NPF_TABLE_RBTREE to NPF_TABLE_TREE.
- Add libnpf(3) - a library to control NPF (configuration, ruleset, etc).
- Add NPF support for ftp-proxy(8).
- Add rc.d script for NPF.
- Convert npfctl(8) to use libnpf(3) and thus make it less depressive.
Note: next clean-up step should be a parser, once dholland@ will finish it.
- Add more documentation.
- Various fixes.
