libc0.3: ioctl() incorrectly decodes argument

[Samuel Thibault]

Package: libc0.3
Version: 2.3.2.ds1-22
Severity: normal
Tags: patch, upstream

Hi,

The following code was failing with error
ioctl: (ipc/mig) server type check failure

#include <sys/ioctl.h>
#include <stdio.h>
int main(void)
{
  if (ioctl(1, TIOCDRAIN) < 0)
    perror("ioctl");
  return 0;
}

And actually any ioctl with no parameter will trigger the same error. I
posted a bug and wrote the attached patch which corrects things. For
details, see upstream bts:

Regards,
Samuel
