* enum net_device_flags - &struct net_device flags
*
* These are the &struct net_device flags, they can be set by drivers, the
* kernel and some can be triggered by userspace. Userspace can query and
* set these flags using userspace utilities but there is also a sysfs
* entry available for all dev flags which can be queried and set. These flags
* are shared for all types of net_devices. The sysfs entries are available
* via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
* are annotated below, note that only a few flags can be toggled and some
* other flags are always preserved from the original net_device flags
* even if you try to set them via sysfs. Flags which are always preserved
* are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
* are annotated below as such.
*
* You should have a pretty good reason to be extending these flags.
*
* @IFF_UP: interface is up. Can be toggled through sysfs.
* @IFF_BROADCAST: broadcast address valid. Volatile.
* @IFF_DEBUG: turn on debugging. Can be toggled through sysfs.
* @IFF_LOOPBACK: is a loopback net. Volatile.
* @IFF_POINTOPOINT: interface is has p-p link. Volatile.
* @IFF_NOTRAILERS: avoid use of trailers. Can be toggled through sysfs.
* Volatile.
* @IFF_RUNNING: interface RFC2863 OPER_UP. Volatile.
* @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
* @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
* @IFF_ALLMULTI: receive all multicast packets. Can be toggled through
* sysfs.
* @IFF_MASTER: master of a load balancer. Volatile.
* @IFF_SLAVE: slave of a load balancer. Volatile.
* @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
* @IFF_PORTSEL: can set media type. Can be toggled through sysfs.
* @IFF_AUTOMEDIA: auto media select active. Can be toggled through sysfs.
* @IFF_DYNAMIC: dialup device with changing addresses. Can be toggled
* through sysfs.
* @IFF_LOWER_UP: driver signals L1 up. Volatile.
* @IFF_DORMANT: driver signals dormant. Volatile.
* @IFF_ECHO: echo sent packets. Volatile.

/*
* Compatibility interface for userspace libc header coordination:
*
* Define compatibility macros that are used to control the inclusion or
* exclusion of UAPI structures and definitions in coordination with another
* userspace C library.
*
* This header is intended to solve the problem of UAPI definitions that
* conflict with userspace definitions. If a UAPI header has such conflicting
* definitions then the solution is as follows:
*
* * Synchronize the UAPI header and the libc headers so either one can be
* used and such that the ABI is preserved. If this is not possible then
* no simple compatibility interface exists (you need to write translating
* wrappers and rename things) and you can't use this interface.
*
* Then follow this process:
*
* (a) Include libc-compat.h in the UAPI header.
* e.g. #include <linux/libc-compat.h>
* This include must be as early as possible.
*
* (b) In libc-compat.h add enough code to detect that the comflicting
* userspace libc header has been included first.
*
* (c) If the userspace libc header has been included first define a set of
* guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
* set their values to 0.
*
* (d) Back in the UAPI header with the conflicting definitions, guard the
* definitions with:
* #if __UAPI_DEF_FOO
* ...
* #endif
*
* This fixes the situation where the linux headers are included *after* the
* libc headers. To fix the problem with the inclusion in the other order the
* userspace libc headers must be fixed like this:
*
* * For all definitions that conflict with kernel definitions wrap those
* defines in the following:
* #if !__UAPI_DEF_FOO
* ...
* #endif
*
* This prevents the redefinition of a construct already defined by the kernel.

*
* Documentation
* =============
*
* 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 IFNAMESIZ - 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 IFNAMESIZ - 1
* WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN
* WGDEVICE_A_PUBLIC_KEY: 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: len WG_KEY_LEN
* WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN
* WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
* WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
* WGPEER_A_LAST_HANDSHAKE_TIME: 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: 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 IFNAMESIZ - 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 be removed rather than
* added/updated and/or WGPEER_F_REPLACE_ALLOWEDIPS

*
* Documentation
* =============
*
* 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 IFNAMESIZ - 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 IFNAMESIZ - 1
* WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN
* WGDEVICE_A_PUBLIC_KEY: 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: len WG_KEY_LEN
* WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN
* WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
* WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
* WGPEER_A_LAST_HANDSHAKE_TIME: struct 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: struct in_addr or struct in6_addr
* WGALLOWEDIP_A_CIDR_MASK: NLA_U8
* 1: NLA_NESTED
* ...
* 2: NLA_NESTED
* ...
* ...
* 1: 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 IFNAMESIZ - 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 be removed 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.
* 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
* 1: NLA_NESTED
* ...
* 2: NLA_NESTED
* ...
* ...
* 1: 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 appened 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.
