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.
- Touches IRQ or DMA behavior; this matters for the representative real-device path.
- 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/types.h`, `linux/kernel.h`, `linux/string.h`, `linux/errno.h`, `linux/slab.h`, `linux/skbuff.h`, `linux/init.h`, `linux/kmod.h`.
- Detected declarations: `struct tc_act_pernet_id`, `function tcf_dev_queue_xmit`, `function tcf_action_goto_chain_exec`, `function tcf_free_cookie_rcu`, `function tcf_set_action_cookie`, `function tcf_action_check_ctrlact`, `function free_tcf`, `function offload_action_hw_count_set`, `function offload_action_hw_count_inc`, `function offload_action_hw_count_dec`.
- 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.
- IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.
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.
