|
||||
* =============
|
||||
*
|
||||
* 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.
