The firewall-logger-agent (cfwlogd) is a userland daemon that is responsible
for translating firewall events into newline separated json logs. It does so
by attaching to the kernel device found at /dev/ipfev on a SmartOS system
and reading in a buffer of bytes. Cfwlogd is then responsible for parsing the
buffer into cloud firewall (cfw) logs that will be serialized out to disk. It
is then the job of hermes to upload these logs into the customer's manta
storage.
For more information see rfd-163
In order to build firewall-logger-agent you will need a development zone that has rust 1.33. The component is built by a 2019Q4 image but it is also possible to use 2018Q4 which is an LTS release and also contains rust 1.33.
This will build a debug build with less optimization but faster build times.
cargo build
This will build a release build that generally takes much longer to compile but
results in much faster code. This is what is actually deployed. It's worth
noting that .cargo/config and Cargo.toml include some extra options such as
requiring frame pointers and including debug symbols which are applied in this
mode.
cargo build --release
To run the included tests run the following from the top level directory:
cargo test
One can also run just the individual tests per crate in the workspace by first changing into the subcrate's directory.
Docs can be generated by running:
cargo doc
This project is using the standard rust style guidelines and one should run the following to have formatting applied automatically:
cargo fmt
It's also nice to run the rust clippy tool which will catch a bunch of lints and common mistakes that generally improve the rust code.
cargo clippy
