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/unaligned.h

Detected Declarations

• function eir_precalc_len
• function eir_append_data
• function eir_append_le16
• function eir_skb_put_data

Annotated Snippet

if (eir[1] != type) {
			eir += field_len + 1;
			continue;
		}

		/* Zero length data */
		if (field_len == 1)
			return NULL;

		if (data_len)
			*data_len = field_len - 1;

		return &eir[2];
	}

	return NULL;
}

void *eir_get_service_data(u8 *eir, size_t eir_len, u16 uuid, size_t *len);

Annotation

• Immediate include surface: `linux/unaligned.h`.
• Detected declarations: `function eir_precalc_len`, `function eir_append_data`, `function eir_append_le16`, `function eir_skb_put_data`.
• 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.
