Can not send icmp netunreach packet
Last modified: 2008-03-19 12:47:56 EDT
Description of problem:
There is a bug about icmp netunreach.
If the kernel does not find a route for a packet,
it must send a icmp netunreach packet to the source host,
and discard the packet. But the kernel does not send
a icmp netunreach packet because of the fib_lookup
return value of -ESRCH when a route is not found.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. TN send a echo request to a unknown dest address to NUT
TN can not receive netunreach packet packet
TN can receive netunreach packet packet
