Subject: [NET] Can not send icmp netunreach packet
Date: Mon, 25 Feb 2008 16:28:04 +0800 [thread overview]
Message-ID: <47C27C14.4010208@cn.fujitsu.com> (raw)
Hi Steven
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 latest kernel does not send a icmp netunreach packet
because of the fib_lookup
return value of -ESRCH when a route is not found.
I found a your patch about why
changes the "not found" error return for the
lookup function to -ESRCH. But I think this is not correct.
Your patch is as following:
