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/random.h

Detected Declarations

• struct tipc_basic_hdr
• function tipc_hdr_rps_key

Annotated Snippet

struct tipc_basic_hdr {
	__be32 w[4];
};

static inline __be32 tipc_hdr_rps_key(struct tipc_basic_hdr *hdr)
{
	u32 w0 = ntohl(hdr->w[0]);
	bool keepalive_msg = (w0 & KEEPALIVE_MSG_MASK) == KEEPALIVE_MSG_MASK;
	__be32 key;

	/* Return source node identity as key */
	if (likely(!keepalive_msg))
		return hdr->w[3];

	/* Spread PROBE/PROBE_REPLY messages across the cores */
	get_random_bytes(&key, sizeof(key));
	return key;
}

Annotation

• Immediate include surface: `linux/random.h`.
• Detected declarations: `struct tipc_basic_hdr`, `function tipc_hdr_rps_key`.
• 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.
