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.
• Touches user memory; correctness depends on fault-safe copying and privilege boundary handling.
• 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/module.h`, `linux/kthread.h`, `linux/file.h`, `linux/etherdevice.h`, `linux/unaligned.h`, `net/bluetooth/bluetooth.h`, `net/bluetooth/l2cap.h`, `net/bluetooth/hci_core.h`.
• Detected declarations: `function __bnep_link_session`, `function __bnep_unlink_session`, `function bnep_send`, `function bnep_send_rsp`, `function bnep_set_default_proto_filter`, `function bnep_ctrl_set_netfilter`, `function bnep_ctrl_set_mcfilter`, `function bnep_rx_control_cmd`, `function bnep_rx_control`, `function bnep_rx_extension`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: integration implementation candidate.
• This snippet crosses the user/kernel memory boundary; validate fault handling and access checks before translating the pattern.
• 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.
