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

• net/iw_handler.h

Detected Declarations

• struct net
• function wext_handle_ioctl
• function compat_wext_handle_ioctl
• function wext_proc_init
• function wext_proc_exit

Annotation

• Immediate include surface: `net/iw_handler.h`.
• Detected declarations: `struct net`, `function wext_handle_ioctl`, `function compat_wext_handle_ioctl`, `function wext_proc_init`, `function wext_proc_exit`.
• 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.
