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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/skbuff.h
• linux/rcupdate.h
• linux/udp.h
• net/sock.h
• net/tcp.h
• net/psp/types.h

Detected Declarations

• struct inet_timewait_sock
• function psp_enqueue_set_decrypted
• function __psp_skb_coalesce_diff
• function psp_is_allowed_nondata
• function psp_pse_matches_pas
• function __psp_sk_rx_policy_check
• function psp_sk_rx_policy_check
• function psp_twsk_rx_policy_check
• function psp_sk_overhead
• function psp_sk_assoc_free
• function psp_enqueue_set_decrypted

Annotation

• Immediate include surface: `linux/skbuff.h`, `linux/rcupdate.h`, `linux/udp.h`, `net/sock.h`, `net/tcp.h`, `net/psp/types.h`.
• Detected declarations: `struct inet_timewait_sock`, `function psp_enqueue_set_decrypted`, `function __psp_skb_coalesce_diff`, `function psp_is_allowed_nondata`, `function psp_pse_matches_pas`, `function __psp_sk_rx_policy_check`, `function psp_sk_rx_policy_check`, `function psp_twsk_rx_policy_check`, `function psp_sk_overhead`, `function psp_sk_assoc_free`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: source implementation candidate.

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.
