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.
• 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/rxrpc.h
• linux/ktime.h

Detected Declarations

• struct key
• struct sock
• struct socket
• struct rxrpc_call
• struct rxrpc_peer

• Detected declarations: `struct key`, `struct sock`, `struct socket`, `struct rxrpc_call`, `struct rxrpc_peer`, `struct krb5_buffer`, `struct rxrpc_kernel_ops`, `enum rxrpc_abort_reason`, `enum rxrpc_interruptibility`, `enum rxrpc_oob_type`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: source 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.
