Changed the password prompting code to no longer require the EAP methods to maintain their own stale frame buffer.  (Frame buffer pointers should be moved out of generic_eap_data before a final release.)  Instead, EAP methods should set need_password in generic_eap_data to 1, along with the variables that identify the eap type being used, and the challenge data (if any -- only interesting to OTP/GTC at this point).  Also fixed up xsup_set_pwd.c, and got it back in CVS.  (For some reason, it was in limbo.)  Added xsup_monitor under gui_tools/cli.  xsup_monitor will eventually be a cli program that will monitor XSupplicant (running as a daemon) and display status information, and request passwords when they are not in the config. * * Revision 1.5  2004/03/17 21:21:39  chessing * * Hopefully xsup_set_pwd is in the right place now. ;)  Added the functions needed for xsupplicant to request a password from a GUI client.  (Still needs to be tested.)  Updated TTLS and PEAP to support password prompting.  Fixed up curState change in statemachine.c, so it doesn't print [ALL] in front of the current state. * * Revision 1.1  2004/03/17 21:16:07  chessing * * Moved xsup_set_pwd.c to it's new location. * * Revision 1.3  2004/02/13 05:51:32  chessing * * Removed pieces from sha1.c that were duplicates for OpenSSL calls.  Hopefully this will resolve the TLS issues that have been under discussion on the list.  Added support for a default path for the config file.  If a config file is not specified on the command line, xsupplicant will attempt to read it from /etc/xsupplicant.conf.  Moved code to request a password from each of the EAP types to interface.c/h.  Currently this change is only implemented in the EAP-SIM module.  The changes to the GUI prompt code now make more sense, and are easier to follow.  It will be updated in other EAP types soon. * * Revision 1.2  2004/01/20 00:07:06  chessing * * EAP-SIM fixes. * * Revision 1.1  2004/01/18 06:31:19  chessing * * A few fixes here and there.  Added support in EAP-TLS to wait for a password to be entered from a "GUI" interface.  Added a small CLI utility to pass the password in to the daemon. (In gui_tools/cli)  Made needed IPC updates/changes to support passing in of a generic password to be used. * * *******************************************************************/#include <stdio.h>#include <unistd.h>#include <strings.h>#include <stdlib.h>#include "../../common/gui_interface.h"void usage(char *pname){  printf("Usage: %s -i <interface_name>\n\n\n", pname);  printf("   The interface specified by <interface_name> should be the "	 "interface that you wish to set a password for.\n");}int main(int argc, char *argv[]){  char *theOpts = "i:";  char *passwd, buffer[1520], result[256];  char *intname;  char myint[17];  struct ipc_interface ipcint;  int bufptr, dlen, op;  intname = NULL;  if (is_xsup_running() == FALSE)    {      printf("Error!
