From 5f547391f5f25bb71f27860ad25bd1e4715f0752 Mon Sep 17 00:00:00 2001 From: Joe Stringer Date: Wed, 3 Feb 2016 10:00:10 -0800 Subject: [PATCH] netfilter: nf_defrag_ipv4: Drop redundant ip_send_check() Since commit 0848f6428ba3 ("inet: frags: fix defragmented packet's IP header for af_packet"), ip_send_check() would be called twice for defragmentation that occurs from netfilter ipv4 defrag hooks. Remove the extra call.
