Subject: pfinet crashs in tcp_close() because of missing schedule_timeout()

Package: hurd
Version: N/A
Severity: important

Hi,
with ssh I can easily trigger the following assertion failure in
pfinet:

pfinet: ../../pfinet/glue-include/linux/sched.h:156: schedule_timeout:
Assertion `!"schedule_timeout"' failed.

Here the function from sched.h:

static inline long
schedule_timeout (long timeout)
{
  /* XXX this is only ever called to do SO_LINGER, which we don't support */
  assert (!"schedule_timeout");
  return 0;
}

Marcus suggested to undefine SO_LINGER. That seems to be the right
solution, currently. Otherwise we would need to implement a
schedule_timeout() function. Linux' schedule_timeout() depends on a
lot of other functions, it can't be simply plugged into pfinet.

SO_LINGER doesn't crash the system anymore, although close() is not
synchronized yet.  But that is another issue, so I am closing this report.

Thanks,
Marcus
