staging: irda: remove the irda network stack and drivers

No one has publicly stepped up to maintain this broken codebase for
devices that no one uses anymore, so let's just drop the whole thing.

If someone really wants/needs it, we can revert this and they can fix
the code up to work properly.

- *			    IMPORTANT NOTE
- *			    --------------
- *
- * As of kernel 2.5.20, this is the state of compliance and testing of
- * this driver (irda-usb) with regards to the USB low level drivers...
- *
- * This driver has been tested SUCCESSFULLY with the following drivers :
- *	o usb-uhci-hcd	(For Intel/Via USB controllers)
- *	o uhci-hcd	(Alternate/JE driver for Intel/Via USB controllers)
- *	o ohci-hcd	(For other USB controllers)
- *
- * This driver has NOT been tested with the following drivers :
- *	o ehci-hcd	(USB 2.0 controllers)
- *
- * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly,
- * so we don't have to worry about that anymore.
- * One common problem is the failure to set the address on the dongle,
- * but this happens before the driver gets loaded...
- *
- * Jean II

-/*
- * This is my current (2007-04-25) understanding of how this dongle is supposed
- * to work. This is based on reverse-engineering and examination of the packet
- * data sent and received by the WinXP driver using USBSnoopy. Feel free to
- * update here as more of this dongle is known:
- *
- * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
- * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
- * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
- * order to receive data.
- * Transmission: Just like stir4200, this dongle uses a raw stream of data,
- * which needs to be wrapped and escaped in a similar way as in stir4200.c.
- * Reception: Poll-based, as in stir4200. Each read returns the contents of a
- * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
- * (1-7) of valid data contained within the remaining 7 bytes. For example, if
- * the buffer had the following contents:
- *  06 ff ff ff c0 01 04 aa
- * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
- * end is garbage (left over from a previous reception) and is discarded.
- * If a read returns an "impossible" value as the length of valid data (such as
- * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
- * first plug-in) and its contents should be discarded. There is currently no
- * evidence that the top 5 bits of the 1st byte of the buffer can have values
- * other than 0 once reception begins.
- * Once valid bytes are collected, the assembled stream is a sequence of
- * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
- * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
- * a successful read from the host, which means that in absence of further
- * reception, repeated reads from the dongle will return the exact same
- * contents repeatedly. Attempts to be smart and cache a previous read seem
- * to result in corrupted packets, so this driver depends on the unwrap logic
- * to sort out any repeated reads.
- * Speed change: no commands observed so far to change speed, assumed fixed
- * 9600bps (SIR).

-/*
- * Following is my most current (2007-07-17) understanding of how the Kingsun
- * KS-959 dongle is supposed to work. This information was deduced by
- * reverse-engineering and examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * My most sincere thanks must go to Domen Puncer <domen@coderock.org> for
- * invaluable help in cracking the obfuscation and padding required for this
- * dongle.
- *
- * General: This dongle exposes one interface with one interrupt IN endpoint.
- * However, the interrupt endpoint is NOT used at all for this dongle. Instead,
- * this dongle uses control transfers for everything, including sending and
- * receiving the IrDA frame data. Apparently the interrupt endpoint is just a
- * dummy to ensure the dongle has a valid interface to present to the PC.And I
- * thought the DonShine dongle was weird... In addition, this dongle uses
- * obfuscation (?!?!), applied at the USB level, to hide the traffic, both sent
- * and received, from the dongle. I call it obfuscation because the XOR keying
- * and padding required to produce an USB traffic acceptable for the dongle can
- * not be explained by any other technical requirement.
- *
- * Transmission: To transmit an IrDA frame, the driver must prepare a control
- * URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          <length of valid data before padding, little endian>
- *    wIndex          0x0000
- *    wLength         <length of padded data>
- * The payload packet must be manually wrapped and escaped (as in stir4200.c),
- * then padded and obfuscated before being sent. Both padding and obfuscation
- * are implemented in the procedure obfuscate_tx_buffer(). Suffice to say, the
- * designer/programmer of the dongle used his name as a source for the
- * obfuscation. WTF?!
- * Apparently the dongle cannot handle payloads larger than 256 bytes. The
- * driver has to perform fragmentation in order to send anything larger than
- * this limit.
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with control URBs and the following as a setup packet:
- *    bRequestType    USB_DIR_IN | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x01
- *    wValue          0x0200
- *    wIndex          0x0000
- *    wLength         0x0800 (size of available buffer)
- * If there is data to be read, it will be returned as the response payload.
- * This data is (apparently) not padded, but it is obfuscated. To de-obfuscate
- * it, the driver must XOR every byte, in sequence, with a value that starts at
- * 1 and is incremented with each byte processed, and then with 0x55. The value
- * incremented with each byte processed overflows as an unsigned char. The
- * resulting bytes form a wrapped SIR frame that is unwrapped and unescaped
- * as in stir4200.c The incremented value is NOT reset with each frame, but is
- * kept across the entire session with the dongle. Also, the dongle inserts an
- * extra garbage byte with value 0x95 (after decoding) every 0xff bytes, which
- * must be skipped.
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          0x0200
- *    wIndex          0x0001
- *    wLength         0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- *     __u32 baudSpeed;
- *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
- *    unsigned int : 1;
- *    unsigned int stopBits : 1;
- *    unsigned int parityEnable : 1;
- *    unsigned int parityType : 1;
- *    unsigned int : 1;
- *    unsigned int reset : 1;
- *    unsigned char reserved[3];    // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 57600 bps. Although the
- * package announces support for up to 4MBps, tests with a Sony Ericcson K300
- * phone show corruption when receiving large frames at 115200 bps, the highest
- * speed announced by the phone. However, transmission at 115200 bps is OK. Go
- * figure. Since I don't know whether the phone or the dongle is at fault, max
- * announced speed is 57600 bps until someone produces a device that can run
- * at higher speeds with this dongle.

-/*
- * Following is my most current (2007-07-26) understanding of how the Kingsun
- * 07D0:4100 dongle (sometimes known as the MA-660) is supposed to work. This
- * information was deduced by examining the USB traffic captured with USBSnoopy
- * from the WinXP driver. Feel free to update here as more of the dongle is
- * known.
- *
- * General: This dongle exposes one interface with two interrupt endpoints, one
- * IN and one OUT. In this regard, it is similar to what the Kingsun/Donshine
- * dongle (07c0:4200) exposes. Traffic is raw and needs to be wrapped and
- * unwrapped manually as in stir4200, kingsun-sir, and ks959-sir.
- *
- * Transmission: To transmit an IrDA frame, it is necessary to wrap it, then
- * split it into multiple segments of up to 7 bytes each, and transmit each in
- * sequence. It seems that sending a single big block (like kingsun-sir does)
- * won't work with this dongle. Each segment needs to be prefixed with a value
- * equal to (unsigned char)0xF8 + <number of bytes in segment>, inside a payload
- * of exactly 8 bytes. For example, a segment of 1 byte gets prefixed by 0xF9,
- * and one of 7 bytes gets prefixed by 0xFF. The bytes at the end of the
- * payload, not considered by the prefix, are ignored (set to 0 by this
- * implementation).
- *
- * Reception: To receive data, the driver must poll the dongle regularly (like
- * kingsun-sir.c) with interrupt URBs. If data is available, it will be returned
- * in payloads from 0 to 8 bytes long. When concatenated, these payloads form
- * a raw IrDA stream that needs to be unwrapped as in stir4200 and kingsun-sir
- *
- * Speed change: To change the speed of the dongle, the driver prepares a
- * control URB with the following as a setup packet:
- *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
- *    bRequest        0x09
- *    wValue          0x0200
- *    wIndex          0x0001
- *    wLength         0x0008 (length of the payload)
- * The payload is a 8-byte record, apparently identical to the one used in
- * drivers/usb/serial/cypress_m8.c to change speed:
- *     __u32 baudSpeed;
- *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
- *    unsigned int : 1;
- *    unsigned int stopBits : 1;
- *    unsigned int parityEnable : 1;
- *    unsigned int parityType : 1;
- *    unsigned int : 1;
- *    unsigned int reset : 1;
- *    unsigned char reserved[3];    // set to 0
- *
- * For now only SIR speeds have been observed with this dongle. Therefore,
- * nothing is known on what changes (if any) must be done to frame wrapping /
- * unwrapping for higher than SIR speeds. This driver assumes no change is
- * necessary and announces support for all the way to 115200 bps.

- * Belkin is selling a dongle called the SmartBeam.
- * In fact, there is two hardware version of this dongle, of course with
- * the same name and looking the exactly same (grrr...).
- * I guess that I've got the old one, because inside I don't have
- * a jumper for IrDA/ASK...
- *
- * As far as I can make it from info on their web site, the old dongle 
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
- * Note : this driver was written without any info/help from Belkin,
- * so a lot of info here might be totally wrong. Blame me ;-)

-
-/*
- * This driver has currently only been tested on the IRWave IR320ST-2
- *
- * PROTOCOL:
- *
- * The protocol for talking to the TOIM3232 is quite easy, and is
- * designed to interface with RS232 with only level convertors. The
- * BR/~D line on the chip is brought high to signal 'command mode',
- * where a command byte is sent to select the baudrate of the RS232
- * interface and the pulse length of the IRDA output. When BR/~D
- * is brought low, the dongle then changes to the selected baudrate,
- * and the RS232 interface is used for data until BR/~D is brought
- * high again. The initial speed for the TOIMx323 after RESET is
- * 9600 baud.  The baudrate for command-mode is the last selected
- * baud-rate, or 9600 after a RESET.
- *
- * The  dongle I have (below) adds some extra hardware on the front end,
- * but this is mostly directed towards pariasitic power from the RS232
- * line rather than changing very much about how to communicate with
- * the TOIM3232.
- *
- * The protocol to talk to the TOIM4232 chipset seems to be almost
- * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
- * so this code will probably work on that as well, although I haven't
- * tested it on that hardware.
- *
- * Target dongle variations that might be common:
- *
- * DTR and RTS function:
- *   The data sheet for the 4232 has a sample implementation that hooks the
- *   DTR and RTS lines to the RESET and BaudRate/~Data lines of the
- *   chip (through line-converters). Given both DTR and RTS would have to
- *   be held low in normal operation, and the TOIMx232 requires +5V to
- *   signal ground, most dongle designers would almost certainly choose
- *   an implementation that kept at least one of DTR or RTS high in
- *   normal operation to provide power to the dongle, but will likely
- *   vary between designs.
- *
- * User specified command bits:
- *  There are two user-controllable output lines from the TOIMx232 that
- *  can be set low or high by setting the appropriate bits in the
- *  high-nibble of the command byte (when setting speed and pulse length).
- *  These might be used to switch on and off added hardware or extra
- *  dongle features.
- *
- *
- * Target hardware: IRWave IR320ST-2
- *
- * 	The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
- * 	TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transceiver.
- * 	It uses a hex inverter and some discrete components to buffer and
- * 	line convert the RS232 down to 5V.
- *
- * 	The dongle is powered through a voltage regulator, fed by a large
- * 	capacitor. To switch the dongle on, DTR is brought high to charge
- * 	the capacitor and drive the voltage regulator. DTR isn't associated
- * 	with any control lines on the TOIM3232. Parisitic power is also taken
- * 	from the RTS, TD and RD lines when brought high, but through resistors.
- * 	When DTR is low, the circuit might lose power even with RTS high.
- *
- * 	RTS is inverted and attached to the BR/~D input pin. When RTS
- * 	is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
- * 	RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
- * 	mode'.
- *
- * 	For some unknown reason, the RESET line isn't actually connected
- * 	to anything. This means to reset the dongle to get it to a known
- * 	state (9600 baud) you must drop DTR and RTS low, wait for the power
- * 	capacitor to discharge, and then bring DTR (and RTS for data mode)
- * 	high again, and wait for the capacitor to charge, the power supply
- * 	to stabilise, and the oscillator clock to stabilise.
- *
- * 	Fortunately, if the current baudrate is known, the chipset can
- * 	easily change speed by entering command mode without having to
- * 	reset the dongle first.
- *

- *      This function resets the toim3232 dongle. Warning, this function

- * What we should do is:
- * 	0. Pull RESET high
- * 	1. Wait for at least 7us
- * 	2. Pull RESET low
- * 	3. Wait for at least 7us
- * 	4. Pull BR/~D high
- * 	5. Wait for at least 7us
- * 	6. Send control byte to set baud rate
- * 	7. Wait at least 1us after stop bit
- * 	8. Pull BR/~D low
- * 	9. Should then be in data mode
- *
- * Because the IR320ST-2 doesn't have the RESET line connected for some reason,
- * we'll have to do something else.
- *
- * The default speed after a RESET is 9600, so lets try just bringing it up in
- * data mode after switching it off, waiting for the supply capacitor to
- * discharge, and then switch it back on. This isn't actually pulling RESET
- * high, but it seems to have the same effect.
- *
- * This behaviour will probably work on dongles that have the RESET line connected,
- * but if not, add a flag for the IR320ST-2, and implment the above-listed proper
- * behaviour.
- *
- * RTS is inverted and then fed to BR/~D, so to put it in programming mode, we
- * need to have pull RTS low

-F01 Oct/02/02: Modify code for V0.11(move out back to back transfer)
-F02 Oct/28/02: Add SB device ID for 3147 and 3177.
- Comment :
-       jul/09/2002 : only implement two kind of dongle currently.
-       Oct/02/2002 : work on VT8231 and VT8233 .
-       Aug/06/2003 : change driver format to pci driver .
-
-2004-02-16: <sda@bdit.de>
-- Removed unneeded 'legacy' pci stuff.
-- Make sure SIR mode is set (hw_init()) before calling mode-dependent stuff.
-- On speed change from core, don't send SIR frame with new speed. 
-  Use current speed and change speeds later.
-- Make module-param dongle_id actually work.
-- New dongle_id 17 (0x11): TDFS4500. Single-ended SIR only. 
-  Tested with home-grown PCB on EPIA boards.
-- Code cleanup.

-	 *
-	 * We select to operate using fixed MSTRPAGE=0, use ISA DMA
-	 * address restrictions to make the PCI BM api aware of this,
-	 * but ensure the hardware is dealing with real 32bit access.
-	 *
-	 * In detail:
-	 * The chip executes normal 32bit busmaster cycles, i.e.
-	 * drives all 32 address lines. These addresses however are
-	 * composed of [0:23] taken from various busaddr-pointers
-	 * and [24:31] taken from the MSTRPAGE register in the VLSI82C147
-	 * config space. Therefore _all_ busmastering must be
-	 * targeted to/from one single 16MB (busaddr-) superpage!
-	 * The point is to make sure all the allocations for memory
-	 * locations with busmaster access (ring descriptors, buffers)
-	 * are indeed bus-mappable to the same 16MB range (for x86 this
-	 * means they must reside in the same 16MB physical memory address
-	 * range). The only constraint we have which supports "several objects
-	 * mappable to common 16MB range" paradigma, is the old ISA DMA
-	 * restriction to the first 16MB of physical address range.
-	 * Hence the approach here is to enable PCI busmaster support using
-	 * the correct 32bit dma-mask used by the chip. Afterwards the device's
-	 * dma-mask gets restricted to 24bit, which must be honoured somehow by
-	 * all allocations for memory areas to be exposed to the chip ...
-	 *
-	 * Note:
-	 * Don't be surprised to get "Setting latency timer..." messages every
-	 * time when PCI busmastering is enabled for the chip.
-	 * The chip has its PCI latency timer RO fixed at 0 - which is not a
-	 * problem here, because it is never requesting _burst_ transactions.

-	---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).

-	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.

-	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).

-	tristate "IrCOMM protocol"
-	depends on IRDA && TTY
-	help
-	  Say Y here if you want to build support for the IrCOMM protocol.
-	  To compile it as modules, choose M here: the modules will be
-	  called ircomm and ircomm_tty.
-	  IrCOMM implements serial port emulation, and makes it possible to
-	  use all existing applications that understands TTY's with an
-	  infrared link.  Thus you should be able to use application like PPP,
-	  minicom and others.

-
-	  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.

-/*
- * 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.
