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 module_signature
• enum module_signature_type

Annotated Snippet

struct module_signature {
	__u8	algo;		/* Public-key crypto algorithm [0] */
	__u8	hash;		/* Digest algorithm [0] */
	__u8	id_type;	/* Key identifier type [enum module_signature_type] */
	__u8	signer_len;	/* Length of signer's name [0] */
	__u8	key_id_len;	/* Length of key identifier [0] */
	__u8	__pad[3];
	__be32	sig_len;	/* Length of signature data */
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct module_signature`, `enum module_signature_type`.
• 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.
