Why This File Exists

Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.

• Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• struct bpf_nf_ctx
• function bpf_nf_link_attach

Annotated Snippet

struct bpf_nf_ctx {
	const struct nf_hook_state *state;
	struct sk_buff *skb;
};

#if IS_ENABLED(CONFIG_NETFILTER_BPF_LINK)
int bpf_nf_link_attach(const union bpf_attr *attr, struct bpf_prog *prog);
#else
static inline int bpf_nf_link_attach(const union bpf_attr *attr, struct bpf_prog *prog)
{
	return -EOPNOTSUPP;
}
#endif

Annotation

• Detected declarations: `struct bpf_nf_ctx`, `function bpf_nf_link_attach`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
