This repository is part of the Joyent Triton project. See the contribution guidelines -- Triton does not use GitHub PRs -- and general documentation at the main Triton project page.

This contains shared code for manipulating Triton firewall rules. There are two parts to this package:

  • A Jison grammar (src/fwrule.jison) that specifies a DSL for writing firewall rules. This is used to generate the parser (lib/parser.js)
  • A rule object that wraps the parser and provides various convenience and serialization methods.

The parser is currently checked in to avoid requiring jison to be installed in order to use this package.

After making changes to this repo, repos which depend on it should be updated and tested appropriately:

  • sdc-fwapi should have the fwrule dependency bumped as needed in its package.json. When a new version of the rule language is released, FWRULE_VERSION should be bumped as needed.
  • smartos-live contains a copy in src/fw/tools/fwrule which gets copied into other locations in the repo by the src/fw/tools/bin/rebuild-node-modules script.
  • sdc-firewaller-agent keeps a checked-in copy of fwadm and therefore fwrule in deps/fw which should be kept in sync with fwadm.

Development

If you update the jison grammar, run the following to regenerate the parser:

make parser

Before checking in, please run:

make check

and fix any warnings. Note that jsstyle will stop after the first file with an error, so you may need to run this multiple times while fixing.

For non-trivial changes, please add a unit test that covers the functionality of the change. If this is a syntax change, update docs/rules.md.in and docs/examples.md.in accordingly.

Testing

To run all tests:

make test

To run an individual test:

./node_modules/.bin/nodeunit <path to test file>
