Malicious ICMP packet causes panic

A network security scan here caused all the RTEMS machines on the network to
RTEMS: icmp_error: bad length
RTEMS: fatal error, exiting
I think that the fix is fairly simple. It's so simple, in fact, that I wonder if I'm missing something. Why did the original authors make the error condition a panic?


Anything using the network stack

Have the Department of Energy probe your network . :-)
