[Proposal] Don't attach cgroup hooks when no pname routing + nonzero so_mark_from_dae

1

### Proposal Cgroup hooks are primarily used for pname-based routing (e.g., pname(NetworkManager) -> direct). If no pname-based routing rules are defined, there is little justification for attaching cgroup hooks. Another...

ringbuf: add zero-copy consumer APIs

The current ringbuf consumer APIs Read/ReadInto always copy samples into a user-provided buffer, see https://github.com/cilium/ebpf/blob/v0.20.0/ringbuf/ring.go#L96. For callers that consume data synchronizely, this extra copy is unnecessary. This change adds a...

Cannot compile backwards jump

5

libpcap in some cases generates "backwards jump" in cbpf, e.g. `tcpdump -d ip6 protochain 17`: ``` ~ $ tcpdump -d ip6 protochain 17 Warning: assuming Ethernet (000) ldh [12] (001)...

Fix jump calculation

Currently, an error is triggered when calling ToEBPF() on cBPF instructions generated by the filter "ip6 protochain 58": $ tcpdump -dd ip6 protochain 58 | cat -n Warning: assuming Ethernet...
