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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/module.h`, `linux/vmalloc.h`, `linux/hyperv.h`, `net/sock.h`, `net/af_vsock.h`, `hyperv/hvhdk.h`.
• Detected declarations: `struct vmpipe_proto_header`, `struct hvs_recv_buf`, `struct hvs_send_buf`, `struct hvsock`, `function is_valid_srv_id`, `function get_port_by_srv_id`, `function hvs_addr_init`, `function hvs_set_channel_pending_send_size`, `function hvs_channel_readable`, `function hvs_channel_readable_payload`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: integration 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.
