+ * 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.

+	@
+	@ Trivia.
+	@
+	@ Result of multiplication of n-bit number by m-bit number is
+	@ n+m bits wide. However! Even though 2^n is a n+1-bit number,
+	@ m-bit number multiplied by 2^n is still n+m bits wide.
+	@
+	@ Sum of two n-bit numbers is n+1 bits wide, sum of three - n+2,
+	@ and so is sum of four. Sum of 2^m n-m-bit numbers and n-bit
+	@ one is n+1 bits wide.
+	@
+	@ >>+ denotes Hnext += Hn>>26, Hn &= 0x3ffffff. This means that
+	@ H0, H2, H3 are guaranteed to be 26 bits wide, while H1 and H4
+	@ can be 27. However! In cases when their width exceeds 26 bits
+	@ they are limited by 2^26+2^6. This in turn means that *sum*
+	@ of the products with these values can still be viewed as sum
+	@ of 52-bit numbers as long as the amount of addends is not a
+	@ power of 2. For example,
+	@
+	@ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4,
+	@
+	@ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or
+	@ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than
+	@ 8 * (2^52) or 2^55. However, the value is then multiplied by
+	@ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12),
+	@ which is less than 32 * (2^52) or 2^57. And when processing
+	@ data we are looking at triple as many addends...
+	@
+	@ In key setup procedure pre-reduced H0 is limited by 5*4+1 and
+	@ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the
+	@ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while
+	@ 5*H4 by 5*5*3, or 59[!] bits. How is this relevant? vmlal.u32
+	@ instruction accepts 2x32-bit input and writes 2x64-bit result.
+	@ This means that result of reduction have to be compressed upon
+	@ loop wrap-around. This can be done in the process of reduction
+	@ to minimize amount of instructions [as well as amount of
+	@ 128-bit instructions, which benefits low-end processors], but
+	@ one has to watch for H2 (which is narrower than H0) and 5*H4
+	@ not being wider than 58 bits, so that result of right shift
+	@ by 26 bits fits in 32 bits. This is also useful on x86,
+	@ because it allows to use paddd in place for paddq, which
+	@ benefits Atom, where paddq is ridiculously slow.

+	  WireGuard is a secure, fast, and easy to use replacement for IPSec
+	  that uses modern cryptography and clever networking tricks. It's
+	  designed to be fairly general purpose and abstract enough to fit most
+	  use cases, while at the same time remaining extremely simple to
+	  configure. See www.wireguard.com for more info.
+
+	  It's safe to say Y or M here, as the driver is very lightweight and
+	  is only in use when an administrator chooses to add an interface.
+
+config WIREGUARD_DEBUG
+	bool "Debugging checks and verbose messages"
+	depends on WIREGUARD
+	---help---
+	  This will write log messages for handshake and other events
+	  that occur for a WireGuard interface. It will also perform some
+	  extra validation checks and unit tests at various points. This is
+	  only useful for debugging.
+
+	  Say N here unless you know what you're doing.
