From 23dfe136e2bf8d9ea1095704c535368a9bc721da Mon Sep 17 00:00:00 2001 From: Phil Oester Date: Sat, 16 Nov 2013 20:37:46 -0800 Subject: netfilter: fix wrong byte order in nf_ct_seqadj_set internal information In commit 41d73ec053d2, sequence number adjustments were moved to a separate file. Unfortunately, the sequence numbers that are stored in the nf_ct_seqadj structure are expressed in host byte order. The necessary ntohl call was removed when the call to adjust_tcp_sequence was collapsed into nf_ct_seqadj_set. This broke the FTP NAT helper. Fix it by adding back the byte order conversions.
