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.
- Allocates kernel memory; connect allocation flags and lifetime to context constraints.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Immediate include surface: `linux/bitfield.h`, `linux/list.h`, `linux/netdevice.h`, `linux/xarray.h`, `net/net_namespace.h`, `net/psp.h`, `net/udp.h`, `psp.h`.
- Detected declarations: `function psp_dev_check_access`, `function psp_dev_create`, `function psp_dev_free`, `function psp_dev_unregister`, `function list_for_each_entry_safe`, `function psp_key_size`, `function psp_write_headers`, `function udp_flow_src_port`, `function psp_dev_encapsulate`, `function psp_dev_rcv`.
- 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.
