eBPF table shouldn't drop packets if there is no match

Open osinstom opened this issue 3 years ago • 2 comments

The standard P4 semantics is to implicitly invoke NoAction and continue packet processing. However, eBPF tables for ebpf_model.p4 drop packets if there is no match. We should make the eBPF implementation compliant with the spec.

+1. Has this issue been resolved? I see a linked PR #3129 but do not know whether it is intended to fix this issue, or not.

No one has been working on it - at least not in the simple ebpf backend. Perhaps the PSA backend does it properly.
