OCaml embedded eBPF assembler.

eBPF.mli

Assuming R1 points to packet data - check if it is an ARP packet :

let arp =
[
  ldx H R2 (R1,12);
  movi R0 1;
  jmpi `Exit R2 `EQ 0x806;
  movi R0 0;
label `Exit;
  ret
]

See src/test.ml for more examples.

Build status

Results of building bpf with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
