irda: move net/irda/ to drivers/staging/irda/net/

It's time to get rid of IRDA.  It's long been broken, and no one seems
to use it anymore.  So move it to staging and after a while, we can
delete it from there.

To start, move the network irda core from net/irda to
drivers/staging/irda/net/

-	tristate "IrDA (infrared) subsystem support"
-	select CRC_CCITT
-	---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.

-	help
-	  Say Y here to support the connectionless Ultra IRDA protocol.
-	  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);

-config IRDA_CACHE_LAST_LSAP
-	bool "Cache last LSAP"
-	depends on IRDA
-	help
-	  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.
-
-config IRDA_DEBUG

-	depends on IRDA
-	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).

- *
- *     o SOCK_STREAM:    TinyTP connections with SAR disabled. The
- *                       max SDU size is 0 for conn. of this type

- *                       the message boundaries
- *     o SOCK_DGRAM:     IRDAPROTO_UNITDATA: TinyTP connections with Unitdata
- *                       (unreliable) transfers
- *                       IRDAPROTO_ULTRA: Connectionless and unreliable data

-	 * by a process and the socket layer already prevent the
-	 * socket to go away while a process is holding it, through
-	 * sockfd_put() and fput()...

-	 * 3) This may include deferred TSAP closure. In particular,

-	  Say Y here if you want to build support for the IrLAN protocol.
-	  To compile it as a module, choose M here: the module will be called
-	  irlan.  IrLAN emulates an Ethernet and makes it possible to put up
-	  a wireless LAN using infrared beams.
-
-	  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
-	  to another Linux machine running the IrLAN protocol for ad-hoc
-	  networking!

-/************************** 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.

- * NOTE :

- *	o most users have only a few elements (== overhead)
- *	o most users never use search, so don't benefit from hashing

- * 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.

- * And reduce wrapper.o by ~900B in the process ;-)

- * Then, we have the addition of ZeroCopy, which is optional
- * (i.e. the driver must initiate it) and improve final processing.
- * (2005 B frame + EOF on P6 200MHz, without 30 to 50 us, with 10 to 25 us)

- * We can also choose where we want to do the CRC calculation. We can

- * From those numbers, it's not clear which is the best strategy, because
