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

• linux/types.h

Detected Declarations

• struct xt_socket_mtinfo1
• struct xt_socket_mtinfo2
• struct xt_socket_mtinfo3

Annotated Snippet

struct xt_socket_mtinfo1 {
	__u8 flags;
};
#define XT_SOCKET_FLAGS_V1 XT_SOCKET_TRANSPARENT

struct xt_socket_mtinfo2 {
	__u8 flags;
};
#define XT_SOCKET_FLAGS_V2 (XT_SOCKET_TRANSPARENT | XT_SOCKET_NOWILDCARD)

struct xt_socket_mtinfo3 {
	__u8 flags;
};
#define XT_SOCKET_FLAGS_V3 (XT_SOCKET_TRANSPARENT \
			   | XT_SOCKET_NOWILDCARD \
			   | XT_SOCKET_RESTORESKMARK)

#endif /* _XT_SOCKET_H */

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct xt_socket_mtinfo1`, `struct xt_socket_mtinfo2`, `struct xt_socket_mtinfo3`.
• 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.
