+/*
+ * 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...

+ * --------
+ * Alan Cox start some incompatibles changes. I've integrated a bit more.
+ * - Encryption renamed to Encode to avoid US regulation problems
+ * - Frequency changed from float to struct to avoid problems on old 386
+ *
+ * V3 to V4
+ * --------
+ * - Add sensitivity
+ *
+ * V4 to V5
+ * --------
+ * - Missing encoding definitions in range
+ * - Access points stuff
+ *
+ * V5 to V6
+ * --------
+ * - 802.11 support (ESSID ioctls)
+ *
+ * V6 to V7
+ * --------
+ * - define IW_ESSID_MAX_SIZE and IW_MAX_AP
+ *
+ * V7 to V8
+ * --------
+ * - Changed my e-mail address
+ * - More 802.11 support (nickname, rate, rts, frag)
+ * - List index in frequencies
+ *
+ * V8 to V9
+ * --------

+SHA-1 in C

+100% Public Domain
+
+-----------------
+Modified 7/98
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+ void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+ void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it. This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'
