From 96d9703050a0036a3360ec98bb41e107c90664fe Mon Sep 17 00:00:00 2001 From: Xin Long Date: Wed, 9 Aug 2017 18:15:19 +0800 Subject: net: sched: set xt_tgchk_param par.nft_compat as 0 in ipt_init_target Commit 55917a21d0cc ("netfilter: x_tables: add context to know if extension runs from nft_compat") introduced a member nft_compat to xt_tgchk_param structure. But it didn't set it's value for ipt_init_target. With unexpected value in par.nft_compat, it may return unexpected result in some target's checkentry. This patch is to set all it's fields as 0 and only initialize the non-zero fields in ipt_init_target. v1->v2: As Wang Cong's suggestion, fix it by setting all it's fields as 0 and only initializing the non-zero fields.
