Description Jacques Garrigue 2002-11-26 14:50:00 UTC 
Sun's linux jdk1.4.1 implements java.net.NetworkInterface.getNetworkInterfaces
by first calling SIOCGIFCONF with a NULL buffer, expecting the buffer size as
result.
This call pattern was not implemented /sys/compat/linux/linux_ioctl.c.
The following patch appears to solve the problem.

Fix: Apply the following patch
How-To-Repeat: Calling java.net.NetworkInterface.getNetworkInterfaces() returns null.
