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

• function dctcp_ece_ack_cwr
• function dctcp_ece_ack_update

Annotated Snippet

if (inet_csk(sk)->icsk_ack.pending & ICSK_ACK_TIMER) {
			dctcp_ece_ack_cwr(sk, *ce_state);
			__tcp_send_ack(sk, *prior_rcv_nxt, 0);
		}
		inet_csk(sk)->icsk_ack.pending |= ICSK_ACK_NOW;
	}
	*prior_rcv_nxt = tcp_sk(sk)->rcv_nxt;
	*ce_state = new_ce_state;
	dctcp_ece_ack_cwr(sk, new_ce_state);

Annotation

• Detected declarations: `function dctcp_ece_ack_cwr`, `function dctcp_ece_ack_update`.
• 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.
