Message-ID: <4663A561.7070300@cn.fujitsu.com> Date: Mon, 04 Jun 2007 13:38:41 +0800 From: Wei Yongjun <yjwei@...fujitsu.com> To: Herbert Xu <herbert@...dor.apana.org.au> CC: netdev@...r.kernel.org Subject: Re: [PATCH] Fix bug of update IPv4 PMTU when received ICMP Fragmentation Needed message I know, I misunderstand the iph->tot_len, the ICMP payload is not contained a valid ipv4 packet. I do this under IPv6, it has no problem because IPv6 does not check this. ^_^ Thank you very much. > But this is not the old_mtu field that we were talking about. The > old_mtu field comes from iph->tot_len which is the length of field > in the *original* IP header.
