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.

Annotation

• Immediate include surface: `linux/netdevice.h`, `linux/notifier.h`, `linux/rtnetlink.h`, `net/busy_poll.h`, `net/net_namespace.h`, `net/netdev_queues.h`, `net/netdev_rx_queue.h`, `net/sock.h`.
• Detected declarations: `struct netdev_nl_dump_ctx`, `function netdev_nl_dev_fill`, `function netdev_genl_dev_notify`, `function netdev_nl_dev_get_doit`, `function netdev_nl_dev_get_dumpit`, `function for_each_netdev_lock_scoped`, `function netdev_nl_napi_fill_one`, `function netdev_nl_napi_get_doit`, `function netdev_nl_napi_dump_one`, `function netdev_nl_napi_get_dumpit`.
• 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.
