- * @dev_root: Default device to use as the parent.
- * @bus_groups: Default attributes of the bus.
- * @dev_groups: Default attributes of the devices on the bus.
- * @drv_groups: Default attributes of the device drivers on the bus.
- * @match: Called, perhaps multiple times, whenever a new device or driver
- * is added for this bus. It should return a positive value if the
- * given device can be handled by the given driver and zero
- * otherwise. It may also return error code if determining that
- * the driver supports the device is not possible. In case of
- * -EPROBE_DEFER it will queue the device for deferred probing.
- * @uevent: Called when a device is added, removed, or a few other things
- * that generate uevents to add the environment variables.
- * @probe: Called when a new device or driver add to this bus, and callback
- * the specific driver's probe to initial the matched device.
- * @sync_state: Called to sync device state to software state after all the
- * state tracking consumers linked to this device (present at
- * the time of late_initcall) have successfully bound to a
- * driver. If the device has no consumers, this function will
- * be called at late_initcall_sync level. If the device has
- * consumers that are never bound to a driver, this function
- * will never get called until they do.
- * @remove: Called when a device removed from this bus.
- * @shutdown: Called at shut-down time to quiesce the device.
- *
- * @online: Called to put the device back online (after offlining it).
- * @offline: Called to put the device offline for hot-removal. May fail.
- *
- * @suspend: Called when a device on this bus wants to go to sleep mode.
- * @resume: Called to bring a device on this bus out of sleep mode.
- * @num_vf: Called to find out how many virtual functions a device on this
- * bus supports.
- * @dma_configure: Called to setup DMA configuration on a device on
- * this bus.
- * @pm: Power management operations of this bus, callback the specific
- * device driver's pm-ops.
- * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
- * driver implementations to a bus and allow the driver to do
- * bus-specific setup
- * @p: The private data of the driver core, only the driver core can
- * touch this.
- * @lock_key: Lock class key for use by the lock validator
- * @need_parent_lock: When probing or removing a device on this bus, the
- * device core should lock the device's parent.
- *
- * A bus is a channel between the processor and one or more devices. For the
- * purposes of the device model, all devices are connected via a bus, even if
- * it is an internal, virtual, "platform" bus. Buses can plug into each other.
- * A USB controller is usually a PCI device, for example. The device model
- * represents the actual connections between buses and the devices they control.
- * A bus is represented by the bus_type structure. It contains the name, the
- * default attributes, the bus' methods, PM operations, and the driver core's
- * private data.

- * @dev_kobj: The kobject that represents this class and links it into the hierarchy.

- * few other things that generate uevents to add the environment
- * variables.
- * @devnode: Callback to provide the devtmpfs.
- * @class_release: Called to release this class.
- * @dev_release: Called to release the device.
- * @shutdown_pre: Called at shut-down time before driver shutdown.
- * @ns_type: Callbacks so sysfs can detemine namespaces.
- * @namespace: Namespace of the device belongs to this class.
- * @get_ownership: Allows class to specify uid/gid of the sysfs directories
- * for the devices belonging to the class. Usually tied to
- * device's namespace.
- * @pm: The default device power management operations of this class.
- * @p: The private data of the driver core, no one other than the
- * driver core can touch this.
- *
- * A class is a higher-level view of a device that abstracts out low-level
- * implementation details. Drivers may see a SCSI disk or an ATA disk, but,
- * at the class level, they are all simply disks. Classes allow user space
- * to work with devices based on what they do, rather than how they are
- * connected or how they work.

+ * @dev_root: Default device to use as the parent.
+ * @bus_groups: Default attributes of the bus.
+ * @dev_groups: Default attributes of the devices on the bus.
+ * @drv_groups: Default attributes of the device drivers on the bus.
+ * @match: Called, perhaps multiple times, whenever a new device or driver
+ * is added for this bus. It should return a positive value if the
+ * given device can be handled by the given driver and zero
+ * otherwise. It may also return error code if determining that
+ * the driver supports the device is not possible. In case of
+ * -EPROBE_DEFER it will queue the device for deferred probing.
+ * @uevent: Called when a device is added, removed, or a few other things
+ * that generate uevents to add the environment variables.
+ * @probe: Called when a new device or driver add to this bus, and callback
+ * the specific driver's probe to initial the matched device.
+ * @sync_state: Called to sync device state to software state after all the
+ * state tracking consumers linked to this device (present at
+ * the time of late_initcall) have successfully bound to a
+ * driver. If the device has no consumers, this function will
+ * be called at late_initcall_sync level. If the device has
+ * consumers that are never bound to a driver, this function
+ * will never get called until they do.
+ * @remove: Called when a device removed from this bus.
+ * @shutdown: Called at shut-down time to quiesce the device.
+ *
+ * @online: Called to put the device back online (after offlining it).
+ * @offline: Called to put the device offline for hot-removal. May fail.
+ *
+ * @suspend: Called when a device on this bus wants to go to sleep mode.
+ * @resume: Called to bring a device on this bus out of sleep mode.
+ * @num_vf: Called to find out how many virtual functions a device on this
+ * bus supports.
+ * @dma_configure: Called to setup DMA configuration on a device on
+ * this bus.
+ * @pm: Power management operations of this bus, callback the specific
+ * device driver's pm-ops.
+ * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
+ * driver implementations to a bus and allow the driver to do
+ * bus-specific setup
+ * @p: The private data of the driver core, only the driver core can
+ * touch this.
+ * @lock_key: Lock class key for use by the lock validator
+ * @need_parent_lock: When probing or removing a device on this bus, the
+ * device core should lock the device's parent.
+ *
+ * A bus is a channel between the processor and one or more devices. For the
+ * purposes of the device model, all devices are connected via a bus, even if
+ * it is an internal, virtual, "platform" bus. Buses can plug into each other.
+ * A USB controller is usually a PCI device, for example. The device model
+ * represents the actual connections between buses and the devices they control.
+ * A bus is represented by the bus_type structure. It contains the name, the
+ * default attributes, the bus' methods, PM operations, and the driver core's

- * depends on the full plaintext. (Note that ciphertext stealing causes the

- * unlikely: just a 1 in 2^128 chance for two filenames to collide even if they
- * share the same filesystem-specific hashes.
- *
- * However, this scheme isn't immune to intentional collisions, which can be
- * created by anyone able to create arbitrary plaintext filenames and view them
- * without the key. Making the "digest" be a real cryptographic hash like
- * SHA-256 over the full ciphertext would prevent this, although it would be
- * less efficient and harder to implement, especially since the filesystem would

+ * =============
+ *
+ * The below enums and macros are for interfacing with WireGuard, using generic
+ * netlink, with family WG_GENL_NAME and version WG_GENL_VERSION. It defines two
+ * methods: get and set. Note that while they share many common attributes,
+ * these two functions actually accept a slightly different set of inputs and
+ * outputs.
+ *
+ * WG_CMD_GET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST | NLM_F_DUMP. The command should contain
+ * one but not both of:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ *
+ * The kernel will then return several messages (NLM_F_MULTI) containing the
+ * following tree of nested items:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ * WGDEVICE_A_PRIVATE_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ * WGDEVICE_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ * WGDEVICE_A_LISTEN_PORT: NLA_U16
+ * WGDEVICE_A_FWMARK: NLA_U32
+ * WGDEVICE_A_PEERS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGPEER_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ * WGPEER_A_PRESHARED_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ * WGPEER_A_ENDPOINT: NLA_MIN_LEN(struct sockaddr), struct sockaddr_in or struct sockaddr_in6
+ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
+ * WGPEER_A_LAST_HANDSHAKE_TIME: NLA_EXACT_LEN, struct __kernel_timespec
+ * WGPEER_A_RX_BYTES: NLA_U64
+ * WGPEER_A_TX_BYTES: NLA_U64
+ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGALLOWEDIP_A_FAMILY: NLA_U16
+ * WGALLOWEDIP_A_IPADDR: NLA_MIN_LEN(struct in_addr), struct in_addr or struct in6_addr
+ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+ * 0: NLA_NESTED
+ * ...
+ * 0: NLA_NESTED
+ * ...
+ * ...
+ * WGPEER_A_PROTOCOL_VERSION: NLA_U32
+ * 0: NLA_NESTED
+ * ...
+ * ...
+ *
+ * It is possible that all of the allowed IPs of a single peer will not
+ * fit within a single netlink message. In that case, the same peer will
+ * be written in the following message, except it will only contain
+ * WGPEER_A_PUBLIC_KEY and WGPEER_A_ALLOWEDIPS. This may occur several
+ * times in a row for the same peer. It is then up to the receiver to
+ * coalesce adjacent peers. Likewise, it is possible that all peers will
+ * not fit within a single message. So, subsequent peers will be sent
+ * in following messages, except those will only contain WGDEVICE_A_IFNAME
+ * and WGDEVICE_A_PEERS. It is then up to the receiver to coalesce these
+ * messages to form the complete list of peers.
+ *
+ * Since this is an NLA_F_DUMP command, the final message will always be
+ * NLMSG_DONE, even if an error occurs. However, this NLMSG_DONE message
+ * contains an integer error code. It is either zero or a negative error
+ * code corresponding to the errno.
+ *
+ * WG_CMD_SET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST. The command should contain the
+ * following tree of nested items, containing one but not both of
+ * WGDEVICE_A_IFINDEX and WGDEVICE_A_IFNAME:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ * WGDEVICE_A_FLAGS: NLA_U32, 0 or WGDEVICE_F_REPLACE_PEERS if all current
+ * peers should be removed prior to adding the list below.
+ * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN, all zeros to remove
+ * WGDEVICE_A_LISTEN_PORT: NLA_U16, 0 to choose randomly
+ * WGDEVICE_A_FWMARK: NLA_U32, 0 to disable
+ * WGDEVICE_A_PEERS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+ * WGPEER_A_FLAGS: NLA_U32, 0 and/or WGPEER_F_REMOVE_ME if the
+ * specified peer should not exist at the end of the
+ * operation, rather than added/updated and/or
+ * WGPEER_F_REPLACE_ALLOWEDIPS if all current allowed
+ * IPs of this peer should be removed prior to adding
+ * the list below and/or WGPEER_F_UPDATE_ONLY if the
+ * peer should only be set if it already exists.
+ * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN, all zeros to remove
+ * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16, 0 to disable
+ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGALLOWEDIP_A_FAMILY: NLA_U16
+ * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
+ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+ * 0: NLA_NESTED
+ * ...
+ * 0: NLA_NESTED
+ * ...
+ * ...
+ * WGPEER_A_PROTOCOL_VERSION: NLA_U32, should not be set or used at
+ * all by most users of this API, as the
+ * most recent protocol will be used when
+ * this is unset. Otherwise, must be set
+ * to 1.
+ * 0: NLA_NESTED
+ * ...
+ * ...
+ *
+ * It is possible that the amount of configuration data exceeds that of
+ * the maximum message length accepted by the kernel. In that case, several
+ * messages should be sent one after another, with each successive one
+ * filling in information not contained in the prior. Note that if
+ * WGDEVICE_F_REPLACE_PEERS is specified in the first message, it probably
+ * should not be specified in fragments that come after, so that the list
+ * of peers is only cleared the first time but appended after. Likewise for
+ * peers, if WGPEER_F_REPLACE_ALLOWEDIPS is specified in the first message
+ * of a peer, it likely should not be specified in subsequent fragments.
+ *
+ * If an error occurs, NLMSG_ERROR will reply containing an errno.
