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.

Dependency Surface

• linux/module.h
• rdma/rdma_cm.h
• rds_single_path.h
• rdma_transport.h
• ib.h

Detected Declarations

• function rds_rdma_cm_event_handler_cmn
• function rds_rdma_cm_event_handler
• function rds6_rdma_cm_event_handler
• function rds_rdma_listen_init_common
• function rds_rdma_listen_init
• function rds_rdma_listen_stop
• function rds_rdma_init
• function rds_rdma_exit
• module init rds_rdma_init

Annotation

• Immediate include surface: `linux/module.h`, `rdma/rdma_cm.h`, `rds_single_path.h`, `rdma_transport.h`, `ib.h`.
• Detected declarations: `function rds_rdma_cm_event_handler_cmn`, `function rds_rdma_cm_event_handler`, `function rds6_rdma_cm_event_handler`, `function rds_rdma_listen_init_common`, `function rds_rdma_listen_init`, `function rds_rdma_listen_stop`, `function rds_rdma_init`, `function rds_rdma_exit`, `module init rds_rdma_init`.
• 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.
