Hi Carol,
This is Samir Kumar Mishra from India.
I was just looking at this bug -6490935.(passwd does not handle
Control-D input correctly)
I think we can make the fix by doing the following changes in getresponse():
**************************************************************************************************
char *getresponse(char *oldval)
{
char resp[MAX_INPUT_LEN];
char *retval = NULL;
int resplen;
char c;
if(c==-2) {
retval=&c;
fprintf(stderr,MSG_CTRL,c);
passwd_exit(CTRL);
} else {
(void) fgets(resp, sizeof (resp) - 1, stdin);
resplen = strlen(resp) - 1;
if (resp[resplen] == '\n')
resp[resplen] = '\0';
if (*resp != '\0' && strcmp(resp, oldval) != 0)
retval = strdup(resp);
return (retval);
}
}
***************************************************************************************************
In the above MSG_CTRL is a macro defined under the messages column as
#define MSG_CTRL "You have typed %c (or Ctrl-D) which is unacceptable\n"
And CTRL is a macro defined under the exit values column as
#define CTRL 11 /*Exit value for typing Ctrl-D*/
***************************************************************************************************
Now we include this CTRL macro under the switch-case block of
passwd-_exit() function
before the default block:
case CTRL:
(void) fprintf(stderr, "%s\n", gettext(MSG_SHELL_UNCHANGED));
break;
****************************************************************************************************
Now when we type 'passwd -e' in the shell and when prompted for a new
shell, we type
Ctrl-D, the output is
You have pressed #(or Ctrl-D) which is unacceptable.
Login shell unchanged.
***************************************************************************************************
Note: # in the above refers to a unwanted character
I have used c == -2 because when i wanted to test what number
corresponds to the character
generated by pressing Ctrl-D.
Here is another idea.If we could know what signal is generated when
Ctrl-D is pressed then we can do it more easily.
I hope this works out. I would be happier if i can work as your
team-member also.
