Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct vip
• struct iptnl_info

Annotated Snippet

struct vip {
	union {
		__u32 v6[4];
		__u32 v4;
	} daddr;
	__u16 dport;
	__u16 family;
	__u8 protocol;
};

struct iptnl_info {
	union {
		__u32 v6[4];
		__u32 v4;
	} saddr;
	union {
		__u32 v6[4];
		__u32 v4;
	} daddr;
	__u16 family;
	__u8 dmac[6];
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct vip`, `struct iptnl_info`.
• Atlas domain: Support Tooling And Documentation / tools.
• 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.
