From: Jiri Slaby Date: Wed, 24 Oct 2018 12:36:28 +0200 Subject: netfilter: bridge: define INT_MIN & INT_MAX in userspace MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Patch-mainline: submitted on 2018/10/24 References: 4.19 fixes With 4.19, programs like ebtables fail to build when they include "linux/netfilter_bridge.h". It is caused by commit 94276fa8a2a4 which added a use of INT_MIN and INT_MAX to the header: : In file included from /usr/include/linux/netfilter_bridge/ebtables.h:18, : from include/ebtables_u.h:28, : from communication.c:23: : /usr/include/linux/netfilter_bridge.h:30:20: error: 'INT_MIN' undeclared here (not in a function) : NF_BR_PRI_FIRST = INT_MIN, : ^~~~~~~ Define these constants by including "limits.h" when !__KERNEL__ (the same way as for other netfilter_* headers).
