From 89cee8b1cbb9dac40c92ef1968aea2b45f82fd18 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Dec 2005 23:14:27 -0800 Subject: [IPV4]: Safer reassembly Another spin of Herbert Xu's "safer ip reassembly" patch for 2.6.16. (The original patch is here: http://marc.theaimsgroup.com/?l=linux-netdev&m=112281936522415&w=2 and my only contribution is to have tested it.) This patch (optionally) does additional checks before accepting IP fragments, which can greatly reduce the possibility of reassembling fragments which originated from different IP datagrams.
