Hi,
The return value from the getFlags() method in NetworkInterface.c is
interpreted in 2 ways.
- If the value is negative an Exception is thrown
- Else the return value is considered as the flag mask obtained via the
ioctl call.
In rare cases is it possible the value in the ifr_flags could be
negative. One such case is VIPA interfaces. any calls like isUp() on
such network interfaces would end up in a Socket Exception.
I have patch for this. Anyone would like to take a look ?
