Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• net/ip.h
• linux/ipv6.h
• uapi/linux/errqueue.h

Detected Declarations

• struct sock_exterr_skb

Annotated Snippet

struct sock_exterr_skb {
	union {
		struct inet_skb_parm	h4;
#if IS_ENABLED(CONFIG_IPV6)
		struct inet6_skb_parm	h6;
#endif
	} header;
	struct sock_extended_err	ee;
	u16				addr_offset;
	__be16				port;
	u8				opt_stats:1,
					unused:7;
};

Annotation

• Immediate include surface: `net/ip.h`, `linux/ipv6.h`, `uapi/linux/errqueue.h`.
• Detected declarations: `struct sock_exterr_skb`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
