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.
- Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Immediate include surface: `linux/types.h`, `linux/socket.h`, `linux/kernel.h`, `linux/module.h`, `linux/skbuff.h`, `linux/mm.h`, `net/sock.h`, `net/genetlink.h`.
- Detected declarations: `function Copyright`, `function handshake_nl_accept_doit`, `function handshake_nl_done_doit`, `function handshake_net_init`, `function handshake_net_exit`, `function handshake_init`, `function handshake_exit`, `module init handshake_init`, `export handshake_genl_put`.
- Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
- Implementation status: integration implementation candidate.
- Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
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.
