Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+/*
+ * 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 collegues 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.
