Pull networking updates from David Miller:

 1) Support ipv6 checksum offload in sunvnet driver, from Shannon
    Nelson.

 2) Move to RB-tree instead of custom AVL code in inetpeer, from Eric
    Dumazet.

 3) Allow generic XDP to work on virtual devices, from John Fastabend.

 4) Add bpf device maps and XDP_REDIRECT, which can be used to build
    arbitrary switching frameworks using XDP. From John Fastabend.

 5) Remove UFO offloads from the tree, gave us little other than bugs.

 6) Remove the IPSEC flow cache, from Florian Westphal.

 7) Support ipv6 route offload in mlxsw driver.

 8) Support VF representors in bnxt_en, from Sathya Perla.

 9) Add support for forward error correction modes to ethtool, from
    Vidya Sagar Ravipati.

10) Add time filter for packet scheduler action dumping, from Jamal Hadi
    Salim.

11) Extend the zerocopy sendmsg() used by virtio and tap to regular
    sockets via MSG_ZEROCOPY. From Willem de Bruijn.

12) Significantly rework value tracking in the BPF verifier, from Edward
    Cree.

13) Add new jump instructions to eBPF, from Daniel Borkmann.

14) Rework rtnetlink plumbing so that operations can be run without
    taking the RTNL semaphore. From Florian Westphal.

15) Support XDP in tap driver, from Jason Wang.

16) Add 32-bit eBPF JIT for ARM, from Shubham Bansal.

17) Add Huawei hinic ethernet driver.

18) Allow to report MD5 keys in TCP inet_diag dumps, from Ivan
    Delalande.

+ * paths are already called with rtnl_lock() acquired in. There is also an
+ * ASSERT_RTNL() to ensure that we are calling with rtnl acquired. For
+ * dereference here, we will need to use rtnl_dereference(). Dev list writing
+ * needs to happen with rtnl_lock() acquired for netdev_master_upper_dev_link().
+ * For the reader path, the real_dev->rx_handler_data is called in the TX / RX
+ * path. We only need rcu_read_lock() for these scenarios. In these cases,
+ * the rcu_read_lock() is held in __dev_queue_xmit() and
+ * netif_receive_skb_internal(), so readers need to use rcu_dereference_rtnl()
+ * to get the relevant information. For dev list reading, we again acquire
+ * rcu_read_lock() in rmnet_dellink() for netdev_master_upper_dev_get_rcu().
+ * We also use unregister_netdevice_many() to free all rmnet devices in
+ * rmnet_force_unassociate_device() so we dont lose the rtnl_lock() and free in

+	---help---
+	  Say Y here if you want to build support for the IrDA (TM) protocols.
+	  The Infrared Data Associations (tm) specifies standards for wireless
+	  infrared communication and is supported by most laptops and PDA's.
+
+	  To use Linux support for the IrDA (tm) protocols, you will also need
+	  some user-space utilities like irattach.  For more information, see
+	  the file <file:Documentation/networking/irda.txt>.  You also want to
+	  read the IR-HOWTO, available at
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  If you want to exchange bits of data (vCal, vCard) with a PDA, you
+	  will need to install some OBEX application, such as OpenObex :
+	  <http://sourceforge.net/projects/openobex/>
+
+	  To compile this support as a module, choose M here: the module will
+	  be called irda.

+	  Ultra allows to exchange data over IrDA with really simple devices
+	  (watch, beacon) without the overhead of the IrDA protocol (no handshaking,
+	  no management frames, simple fixed header).
+	  Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

+	  Say Y here if you want IrLMP to cache the last LSAP used.  This
+	  makes sense since most frames will be sent/received on the same
+	  connection.  Enabling this option will save a hash-lookup per frame.
+
+	  If unsure, say Y.
+
+config IRDA_FAST_RR
+	bool "Fast RRs (low latency)"
+	depends on IRDA
+	---help---
+	  Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
+	  when acting as a primary station.
+	  Disabling this option will make latency over IrDA very bad. Enabling
+	  this option will make the IrDA stack send more packet than strictly
+	  necessary, thus reduce your battery life (but not that much).
+
+	  Fast RR will make IrLAP send out a RR frame immediately when
+	  receiving a frame if its own transmit queue is currently empty. This
+	  will give a lot of speed improvement when receiving much data since
+	  the secondary station will not have to wait the max. turn around
+	  time (usually 500ms) before it is allowed to transmit the next time.
+	  If the transmit queue of the secondary is also empty, the primary will
+	  start backing-off before sending another RR frame, waiting longer
+	  each time until the back-off reaches the max. turn around time.
+	  This back-off increase in controlled via
+	  /proc/sys/net/irda/fast_poll_increase
+
+	  If unsure, say Y.
+

+	help
+	  Say Y here if you want the IrDA subsystem to write debug information
+	  to your syslog. You can change the debug level in
+	  /proc/sys/net/irda/debug .
+	  When this option is enabled, the IrDA also perform many extra internal
+	  verifications which will usually prevent the kernel to crash in case of
+	  bugs.
+
+	  If unsure, say Y (since it makes it easier to find the bugs).

+ *     Linux-IrDA now supports four different types of IrDA sockets:
+ *
+ *     o SOCK_STREAM:    TinyTP connections with SAR disabled. The
+ *                       max SDU size is 0 for conn. of this type
+ *     o SOCK_SEQPACKET: TinyTP connections with SAR enabled. TTP may
+ *                       fragment the messages, but will preserve
+ *                       the message boundaries
+ *     o SOCK_DGRAM:     IRDAPROTO_UNITDATA: TinyTP connections with Unitdata
+ *                       (unreliable) transfers
+ *                       IRDAPROTO_ULTRA: Connectionless and unreliable data

+
+	  The IrLAN protocol can be used to talk with infrared access points
+	  like the HP NetbeamIR, or the ESI JetEye NET.  You can also connect

+/************************** DOCUMENTATION ***************************/
+/*
+ * What is IrNET
+ * -------------
+ * IrNET is a protocol allowing to carry TCP/IP traffic between two
+ * IrDA peers in an efficient fashion. It is a thin layer, passing PPP
+ * packets to IrTTP and vice versa. It uses PPP in synchronous mode,
+ * because IrTTP offer a reliable sequenced packet service (as opposed
+ * to a byte stream). In fact, you could see IrNET as carrying TCP/IP
+ * in a IrDA socket, using PPP to provide the glue.
+ *
+ * The main difference with traditional PPP over IrCOMM is that we
+ * avoid the framing and serial emulation which are a performance
+ * bottleneck. It also allows multipoint communications in a sensible
+ * fashion.
+ *
+ * The main difference with IrLAN is that we use PPP for the link
+ * management, which is more standard, interoperable and flexible than
+ * the IrLAN protocol. For example, PPP adds authentication,
+ * encryption, compression, header compression and automated routing
+ * setup. And, as IrNET let PPP do the hard work, the implementation
+ * is much simpler than IrLAN.
+ *
+ * The Linux implementation
+ * ------------------------
+ * IrNET is written on top of the Linux-IrDA stack, and interface with
+ * the generic Linux PPP driver. Because IrNET depend on recent
+ * changes of the PPP driver interface, IrNET will work only with very
+ * recent kernel (2.3.99-pre6 and up).
+ *
+ * The present implementation offer the following features :
+ *	o simple user interface using pppd
+ *	o efficient implementation (interface directly to PPP and IrTTP)
+ *	o addressing (you can specify the name of the IrNET recipient)
+ *	o multipoint operation (limited by IrLAP specification)
+ *	o information in /proc/net/irda/irnet
+ *	o IrNET events on /dev/irnet (for user space daemon)
+ *	o IrNET daemon (irnetd) to automatically handle incoming requests
+ *	o Windows 2000 compatibility (tested, but need more work)
+ * Currently missing :
+ *	o Lot's of testing (that's your job)
+ *	o Connection retries (may be too hard to do)
+ *	o Check pppd persist mode
+ *	o User space daemon (to automatically handle incoming requests)
+ *
+ * The setup is not currently the most easy, but this should get much
+ * better when everything will get integrated...
+ *
+ * Acknowledgements
+ * ----------------
+ * This module is based on :
+ *	o The PPP driver (ppp_synctty/ppp_generic) by Paul Mackerras
+ *	o The IrLAN protocol (irlan_common/XXX) by Dag Brattli
+ *	o The IrSock interface (af_irda) by Dag Brattli
+ *	o Some other bits from the kernel and my drivers...
+ * Infinite thanks to those brave souls for providing the infrastructure
+ * upon which IrNET is built.
+ *
+ * Thanks to all my colleagues in HP for helping me. In particular,
+ * thanks to Salil Pradhan and Bill Serra for W2k testing...
+ * Thanks to Luiz Magalhaes for irnetd and much testing...
+ *
+ * Thanks to Alan Cox for answering lot's of my stupid questions, and
+ * to Paul Mackerras answering my questions on how to best integrate
+ * IrNET and pppd.
+ *
+ * Jean II
+ *
+ * Note on some implementations choices...
+ * ------------------------------------
+ *	1) Direct interface vs tty/socket
+ * I could have used a tty interface to hook to ppp and use the full
+ * socket API to connect to IrDA. The code would have been easier to
+ * maintain, and maybe the code would have been smaller...
+ * Instead, we hook directly to ppp_generic and to IrTTP, which make
+ * things more complicated...
+ *
+ * The first reason is flexibility : this allow us to create IrNET
+ * instances on demand (no /dev/ircommX crap) and to allow linkname
+ * specification on pppd command line...
+ *
+ * Second reason is speed optimisation. If you look closely at the
+ * transmit and receive paths, you will notice that they are "super lean"
+ * (that's why they look ugly), with no function calls and as little data
+ * copy and modification as I could...
+ *
+ *	2) irnetd in user space
+ * irnetd is implemented in user space, which is necessary to call pppd.
+ * This also give maximum benefits in term of flexibility and customability,
+ * and allow to offer the event channel, useful for other stuff like debug.
+ *
+ * On the other hand, this require a loose coordination between the
+ * present module and irnetd. One critical area is how incoming request
+ * are handled.
+ * When irnet receive an incoming request, it send an event to irnetd and
+ * drop the incoming IrNET socket.
+ * irnetd start a pppd instance, which create a new IrNET socket. This new
+ * socket is then connected in the originating node to the pppd instance.
+ * At this point, in the originating node, the first socket is closed.
+ *
+ * I admit, this is a bit messy and waste some resources. The alternative
+ * is caching incoming socket, and that's also quite messy and waste
+ * resources.
+ * We also make connection time slower. For example, on a 115 kb/s link it
+ * adds 60ms to the connection time (770 ms). However, this is slower than
+ * the time it takes to fire up pppd on my P133...
+ *
+ *
+ * History :
+ * -------
+ *
+ * v1 - 15.5.00 - Jean II
+ *	o Basic IrNET (hook to ppp_generic & IrTTP - incl. multipoint)
+ *	o control channel on /dev/irnet (set name/address)
+ *	o event channel on /dev/irnet (for user space daemon)
+ *
+ * v2 - 5.6.00 - Jean II
+ *	o Enable DROP_NOT_READY to avoid PPP timeouts & other weirdness...
+ *	o Add DISCONNECT_TO event and rename DISCONNECT_FROM.
+ *	o Set official device number alloaction on /dev/irnet
+ *
+ * v3 - 30.8.00 - Jean II
+ *	o Update to latest Linux-IrDA changes :
+ *		- queue_t => irda_queue_t
+ *	o Update to ppp-2.4.0 :
+ *		- move irda_irnet_connect from PPPIOCATTACH to TIOCSETD
+ *	o Add EXPIRE event (depend on new IrDA-Linux patch)
+ *	o Switch from `hashbin_remove' to `hashbin_remove_this' to fix
+ *	  a multilink bug... (depend on new IrDA-Linux patch)
+ *	o fix a self->daddr to self->raddr in irda_irnet_connect to fix
+ *	  another multilink bug (darn !)
+ *	o Remove LINKNAME_IOCTL cruft
+ *
+ * v3b - 31.8.00 - Jean II
+ *	o Dump discovery log at event channel startup
+ *
+ * v4 - 28.9.00 - Jean II
+ *	o Fix interaction between poll/select and dump discovery log
+ *	o Add IRNET_BLOCKED_LINK event (depend on new IrDA-Linux patch)
+ *	o Add IRNET_NOANSWER_FROM event (mostly to help support)
+ *	o Release flow control in disconnect_indication
+ *	o Block packets while connecting (speed up connections)
+ *
+ * v5 - 11.01.01 - Jean II
+ *	o Init self->max_header_size, just in case...
+ *	o Set up ap->chan.hdrlen, to get zero copy on tx side working.
+ *	o avoid tx->ttp->flow->ppp->tx->... loop, by checking flow state
+ *		Thanks to Christian Gennerat for finding this bug !
+ *	---
+ *	o Declare the proper MTU/MRU that we can support
+ *		(but PPP doesn't read the MTU value :-()
+ *	o Declare hashbin HB_NOLOCK instead of HB_LOCAL to avoid
+ *		disabling and enabling irq twice
+ *
+ * v6 - 31.05.01 - Jean II
+ *	o Print source address in Found, Discovery, Expiry & Request events
+ *	o Print requested source address in /proc/net/irnet
+ *	o Change control channel input. Allow multiple commands in one line.
+ *	o Add saddr command to change ap->rsaddr (and use that in IrDA)
+ *	---
+ *	o Make the IrDA connection procedure totally asynchronous.
+ *	  Heavy rewrite of the IAS query code and the whole connection
+ *	  procedure. Now, irnet_connect() no longer need to be called from
+ *	  a process context...
+ *	o Enable IrDA connect retries in ppp_irnet_send(). The good thing
+ *	  is that IrDA connect retries are directly driven by PPP LCP
+ *	  retries (we retry for each LCP packet), so that everything
+ *	  is transparently controlled from pppd lcp-max-configure.
+ *	o Add ttp_connect flag to prevent rentry on the connect procedure
+ *	o Test and fixups to eliminate side effects of retries
+ *
+ * v7 - 22.08.01 - Jean II
+ *	o Cleanup : Change "saddr = 0x0" to "saddr = DEV_ADDR_ANY"
+ *	o Fix bug in BLOCK_WHEN_CONNECT introduced in v6 : due to the
+ *	  asynchronous IAS query, self->tsap is NULL when PPP send the
+ *	  first packet.  This was preventing "connect-delay 0" to work.
+ *	  Change the test in ppp_irnet_send() to self->ttp_connect.
+ *
+ * v8 - 1.11.01 - Jean II
+ *	o Tighten the use of self->ttp_connect and self->ttp_open to
+ *	  prevent various race conditions.
+ *	o Avoid leaking discovery log and skb
+ *	o Replace "self" with "server" in irnet_connect_indication() to
+ *	  better detect cut'n'paste error ;-)
+ *
+ * v9 - 29.11.01 - Jean II
+ *	o Fix event generation in disconnect indication that I broke in v8
+ *	  It was always generation "No-Answer" because I was testing ttp_open
+ *	  just after clearing it. *blush*.
+ *	o Use newly created irttp_listen() to fix potential crash when LAP
+ *	  destroyed before irnet module removed.
+ *
+ * v10 - 4.3.2 - Jean II
+ *	o When receiving a disconnect indication, don't reenable the
+ *	  PPP Tx queue, this will trigger a reconnect. Instead, close
+ *	  the channel, which will kill pppd...
+ *
+ * v11 - 20.3.02 - Jean II
+ *	o Oops ! v10 fix disabled IrNET retries and passive behaviour.
+ *	  Better fix in irnet_disconnect_indication() :
+ *	  - if connected, kill pppd via hangup.
+ *	  - if not connected, reenable ppp Tx, which trigger IrNET retry.
+ *
+ * v12 - 10.4.02 - Jean II
+ *	o Fix race condition in irnet_connect_indication().
+ *	  If the socket was already trying to connect, drop old connection
+ *	  and use new one only if acting as primary. See comments.
+ *
+ * v13 - 30.5.02 - Jean II
+ *	o Update module init code
+ *
+ * v14 - 20.2.03 - Jean II
+ *	o Add discovery hint bits in the control channel.
+ *	o Remove obsolete MOD_INC/DEC_USE_COUNT in favor of .owner
+ *
+ * v15 - 7.4.03 - Jean II
+ *	o Replace spin_lock_irqsave() with spin_lock_bh() so that we can
+ *	  use ppp_unit_number(). It's probably also better overall...
+ *	o Disable call to ppp_unregister_channel(), because we can't do it.

+/*
+ * Notes on the concurrent access to hashbin and other SMP issues
+ * -------------------------------------------------------------
+ *	Hashbins are very often in the IrDA stack a global repository of
+ * information, and therefore used in a very asynchronous manner following
+ * various events (driver calls, timers, user calls...).
+ *	Therefore, very often it is highly important to consider the
+ * management of concurrent access to the hashbin and how to guarantee the
+ * consistency of the operations on it.
+ *
+ *	First, we need to define the objective of locking :
+ *		1) Protect user data (content pointed by the hashbin)
+ *		2) Protect hashbin structure itself (linked list in each bin)
+ *
+ *			     OLD LOCKING
+ *			     -----------
+ *
+ *	The previous locking strategy, either HB_LOCAL or HB_GLOBAL were
+ * both inadequate in *both* aspect.
+ *		o HB_GLOBAL was using a spinlock for each bin (local locking).
+ *		o HB_LOCAL was disabling irq on *all* CPUs, so use a single
+ *		  global semaphore.
+ *	The problems were :
+ *		A) Global irq disabling is no longer supported by the kernel
+ *		B) No protection for the hashbin struct global data
+ *			o hashbin_delete()
+ *			o hb_current
+ *		C) No protection for user data in some cases
+ *
+ *	A) HB_LOCAL use global irq disabling, so doesn't work on kernel
+ * 2.5.X. Even when it is supported (kernel 2.4.X and earlier), its
+ * performance is not satisfactory on SMP setups. Most hashbins were
+ * HB_LOCAL, so (A) definitely need fixing.
+ *	B) HB_LOCAL could be modified to fix (B). However, because HB_GLOBAL
+ * lock only the individual bins, it will never be able to lock the
+ * global data, so can't do (B).
+ *	C) Some functions return pointer to data that is still in the
+ * hashbin :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *	As the data is still in the hashbin, it may be changed or free'd
+ * while the caller is examinimg the data. In those case, locking can't
+ * be done within the hashbin, but must include use of the data within
+ * the caller.
+ *	The caller can easily do this with HB_LOCAL (just disable irqs).
+ * However, this is impossible with HB_GLOBAL because the caller has no
+ * way to know the proper bin, so don't know which spinlock to use.
+ *
+ *	Quick summary : can no longer use HB_LOCAL, and HB_GLOBAL is
+ * fundamentally broken and will never work.
+ *
+ *			     NEW LOCKING
+ *			     -----------
+ *
+ *	To fix those problems, I've introduce a few changes in the
+ * hashbin locking :
+ *		1) New HB_LOCK scheme
+ *		2) hashbin->hb_spinlock
+ *		3) New hashbin usage policy
+ *
+ * HB_LOCK :

+ *	HB_LOCK is a locking scheme intermediate between the old HB_LOCAL
+ * and HB_GLOBAL. It uses a single spinlock to protect the whole content
+ * of the hashbin. As it is a single spinlock, it can protect the global
+ * data of the hashbin and not only the bins themselves.
+ *	HB_LOCK can only protect some of the hashbin calls, so it only lock
+ * call that can be made 100% safe and leave other call unprotected.
+ *	HB_LOCK in theory is slower than HB_GLOBAL, but as the hashbin
+ * content is always small contention is not high, so it doesn't matter
+ * much. HB_LOCK is probably faster than HB_LOCAL.
+ *
+ * hashbin->hb_spinlock :
+ * --------------------
+ *	The spinlock that HB_LOCK uses is available for caller, so that
+ * the caller can protect unprotected calls (see below).
+ *	If the caller want to do entirely its own locking (HB_NOLOCK), he
+ * can do so and may use safely this spinlock.
+ *	Locking is done like this :
+ *		spin_lock_irqsave(&hashbin->hb_spinlock, flags);
+ *	Releasing the lock :
+ *		spin_unlock_irqrestore(&hashbin->hb_spinlock, flags);
+ *
+ * Safe & Protected calls :
+ * ----------------------
+ *	The following calls are safe or protected via HB_LOCK :
+ *		o hashbin_new()		-> safe
+ *		o hashbin_delete()
+ *		o hashbin_insert()
+ *		o hashbin_remove_first()
+ *		o hashbin_remove()
+ *		o hashbin_remove_this()
+ *		o HASHBIN_GET_SIZE()	-> atomic
+ *
+ *	The following calls only protect the hashbin itself :
+ *		o hashbin_lock_find()
+ *		o hashbin_find_next()
+ *
+ * Unprotected calls :
+ * -----------------
+ *	The following calls need to be protected by the caller :
+ *		o hashbin_find()
+ *		o hashbin_get_first()
+ *		o hashbin_get_next()
+ *
+ * Locking Policy :
+ * --------------
+ *	If the hashbin is used only in a single thread of execution
+ * (explicitly or implicitely), you can use HB_NOLOCK
+ *	If the calling module already provide concurrent access protection,
+ * you may use HB_NOLOCK.
+ *
+ *	In all other cases, you need to use HB_LOCK and lock the hashbin
+ * every time before calling one of the unprotected calls. You also must
+ * use the pointer returned by the unprotected call within the locked
+ * region.
+ *
+ * Extra care for enumeration :
+ * --------------------------
+ *	hashbin_get_first() and hashbin_get_next() use the hashbin to
+ * store the current position, in hb_current.
+ *	As long as the hashbin remains locked, this is safe. If you unlock
+ * the hashbin, the current position may change if anybody else modify
+ * or enumerate the hashbin.
+ *	Summary : do the full enumeration while locked.
+ *
+ *	Alternatively, you may use hashbin_find_next(). But, this will
+ * be slower, is more complex to use and doesn't protect the hashbin
+ * content. So, care is needed here as well.
+ *
+ * Other issues :
+ * ------------
+ *	I believe that we are overdoing it by using spin_lock_irqsave()
+ * and we should use only spin_lock_bh() or similar. But, I don't have
+ * the balls to try it out.
+ *	Don't believe that because hashbin are now (somewhat) SMP safe
+ * that the rest of the code is. Higher layers tend to be safest,
+ * but LAP and LMP would need some serious dedicated love.

+ * (2005 B frame + EOF on P6 200MHz, without 30 to 50 us, with 10 to 25 us)
