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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• net/netlabel.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

/*
 * The following NetLabel payloads are supported by the Unlabeled subsystem.
 *
 * o STATICADD
 *   This message is sent from an application to add a new static label for
 *   incoming unlabeled connections.
 *
 *   Required attributes:
 *
 *     NLBL_UNLABEL_A_IFACE
 *     NLBL_UNLABEL_A_SECCTX
 *
 *   If IPv4 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV4ADDR
 *     NLBL_UNLABEL_A_IPV4MASK
 *
 *   If IPv6 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV6ADDR
 *     NLBL_UNLABEL_A_IPV6MASK
 *
 * o STATICREMOVE
 *   This message is sent from an application to remove an existing static
 *   label for incoming unlabeled connections.
 *
 *   Required attributes:
 *
 *     NLBL_UNLABEL_A_IFACE
 *
 *   If IPv4 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV4ADDR
 *     NLBL_UNLABEL_A_IPV4MASK
 *
 *   If IPv6 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV6ADDR
 *     NLBL_UNLABEL_A_IPV6MASK
 *
 * o STATICLIST
 *   This message can be sent either from an application or by the kernel in
 *   response to an application generated STATICLIST message.  When sent by an
 *   application there is no payload and the NLM_F_DUMP flag should be set.
 *   The kernel should response with a series of the following messages.
 *
 *   Required attributes:
 *
 *     NLBL_UNLABEL_A_IFACE
 *     NLBL_UNLABEL_A_SECCTX
 *
 *   If IPv4 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV4ADDR
 *     NLBL_UNLABEL_A_IPV4MASK
 *
 *   If IPv6 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV6ADDR
 *     NLBL_UNLABEL_A_IPV6MASK
 *
 * o STATICADDDEF
 *   This message is sent from an application to set the default static
 *   label for incoming unlabeled connections.
 *
 *   Required attribute:
 *
 *     NLBL_UNLABEL_A_SECCTX
 *
 *   If IPv4 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV4ADDR
 *     NLBL_UNLABEL_A_IPV4MASK
 *
 *   If IPv6 is specified the following attributes are required:
 *
 *     NLBL_UNLABEL_A_IPV6ADDR
 *     NLBL_UNLABEL_A_IPV6MASK
 *
 * o STATICREMOVEDEF
 *   This message is sent from an application to remove the existing default
 *   static label for incoming unlabeled connections.
 *
 *   If IPv4 is specified the following attributes are required:

Annotation

• Immediate include surface: `net/netlabel.h`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• 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.
