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:
