From 2ee0d3c80fdb7974cfa1c7e25b5048e9fcaf69b6 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 28 Dec 2013 00:59:38 +0100 Subject: [PATCH] netfilter: nf_tables: fix wrong datatype in nft_validate_data_load() This patch fixes dictionary mappings, eg. add rule ip filter input meta dnat set tcp dport map { 22 => 1.1.1.1, 23 => 2.2.2.2 } The kernel was returning -EINVAL in nft_validate_data_load() since the type of the set element data that is passed was the real userspace datatype instead of NFT_DATA_VALUE.
