This is version 20 of the Wireless Extensions. This is the completion of the RtNetlink work I started early 2004, it enables the full Wireless Extension API over RtNetlink. Few comments on the patch : o totally driver transparent, no change in drivers needed. o iwevent were already RtNetlink based since they were created (around 2.5.7). This adds all the regular SET and GET requests over RtNetlink, using the exact same mechanism and data format as iwevents. o This is a Kconfig option, as currently most people have no need for it. Surprisingly, patch is actually small and well encapsulated. o Tested on SMP, attention as been paid to make it 64 bits clean. o Code do probably too many checks and could be further optimised, but better safe than sorry. o RtNetlink based version of the Wireless Tools available on my web page for people inclined to try out this stuff. I would also like to thank Alexey Kuznetsov for his helpful suggestions to make this patch better. Signed-off-by: Jean Tourrilhes <jt@hpl.hp.com> Signed-off-by: John W.

/************************** DOCUMENTATION **************************/
|
|
/*
|
|
* Initial APIs (1996 -> onward) :
|
|
* -----------------------------
|
|
* Basically, the wireless extensions are for now a set of standard ioctl
|
|
* call + /proc/net/wireless
|
|
*
|
|
* The entry /proc/net/wireless give statistics and information on the
|
|
* driver.
|
|
* This is better than having each driver having its entry because
|
|
* its centralised and we may remove the driver module safely.
|
|
*
|
|
* Ioctl are used to configure the driver and issue commands. This is
|
|
* better than command line options of insmod because we may want to
|
|
* change dynamically (while the driver is running) some parameters.
|
|
*
|
|
* The ioctl mechanimsm are copied from standard devices ioctl.
|
|
* We have the list of command plus a structure descibing the
|
|
* data exchanged...
|
|
* Note that to add these ioctl, I was obliged to modify :
|
|
* # net/core/dev.c (two place + add include)
|
|
* # net/ipv4/af_inet.c (one place + add include)
|
|
*
|
|
* /proc/net/wireless is a copy of /proc/net/dev.
|
|
* We have a structure for data passed from the driver to /proc/net/wireless
|
|
* Too add this, I've modified :
|
|
* # net/core/dev.c (two other places)
|
|
* # include/linux/netdevice.h (one place)
|
|
* # include/linux/proc_fs.h (one place)
|
|
*
|
|
* New driver API (2002 -> onward) :
|
|
* -------------------------------
|
|
* This file is only concerned with the user space API and common definitions.
|
|
* The new driver API is defined and documented in :
|
|
* # include/net/iw_handler.h
|
|
*
|
|
* Note as well that /proc/net/wireless implementation has now moved in :
|
|
* # net/core/wireless.c
|
|
*
|
|
* Wireless Events (2002 -> onward) :
|
|
* --------------------------------
|
|
* Events are defined at the end of this file, and implemented in :
|
|
* # net/core/wireless.c
|
|
*
|
|
* Other comments :
|
|
* --------------
|
|
* Do not add here things that are redundant with other mechanisms
|
|
* (drivers init, ifconfig, /proc/net/dev, ...) and with are not
|
|
* wireless specific.
|
|
*
|
|
* These wireless extensions are not magic : each driver has to provide
|
|
* support for them...
|
|
*
|
|
* IMPORTANT NOTE : As everything in the kernel, this is very much a
|
|
* work in progress. Contact me if you have ideas of improvements...
