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

• linux/skbuff.h
• uapi/linux/in.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#ifndef _NF_DUP_IPV4_H_
#define _NF_DUP_IPV4_H_

#include <linux/skbuff.h>
#include <uapi/linux/in.h>

void nf_dup_ipv4(struct net *net, struct sk_buff *skb, unsigned int hooknum,
		 const struct in_addr *gw, int oif);

#endif /* _NF_DUP_IPV4_H_ */

Annotation

• Immediate include surface: `linux/skbuff.h`, `uapi/linux/in.h`.
• 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.
