From bbf31bf18d34caa87dd01f08bf713635593697f2 Mon Sep 17 00:00:00 2001 From: David Ford Date: Sun, 29 Nov 2009 23:02:22 -0800 Subject: ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined previously patched into 2.6.29. Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched, changing from dev_net(dev) to container_of(...). Unfortunately the goto section (out_fail) on oversized packets inside ip_frag_reasm() didn't get touched up as well. Oversized IP packets cause a NULL pointer dereference and immediate hang. I discovered this running openvasd and my previous email on this is titled: NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566 Signed-off-by: David Ford Signed-off-by: David S.
