From a50243ea1f1fe28239a57283ef3a5ec6e8577dfb Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Thu, 3 Nov 2016 21:44:29 +0100 Subject: [PATCH] dnsmasq: Support add-mac option Adds the mac address of the DNS requestor to DNS queries which are forwarded upstream and can be used to do filtering by the upstream servers. This only works if the requestor is on the same subnet as the dnsmasq server The addmac parameter can hold the following values: 0 : mac address is not added 1 : mac address is added in binary format base64 : mac address is added base64 encoded text: : mac address is added in human readable format as hex and colons Signed-off-by: Hans Dedecker --- package/network/services/dnsmasq/Makefile | 2 +- package/network/services/dnsmasq/files/dnsmasq.init | 6 ++++++ 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/package/network/services/dnsmasq/Makefile b/package/network/services/dnsmasq/Makefile index 804242f4e1..861cda7fbe 100644 --- a/package/network/services/dnsmasq/Makefile +++ b/package/network/services/dnsmasq/Makefile @@ -9,7 +9,7 @@ include $(TOPDIR)/rules.mk PKG_NAME:=dnsmasq PKG_VERSION:=2.76 -PKG_RELEASE:=4 +PKG_RELEASE:=5 PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.xz PKG_SOURCE_URL:=http://thekelleys.org.uk/dnsmasq diff --git a/package/network/services/dnsmasq/files/dnsmasq.init b/package/network/services/dnsmasq/files/dnsmasq.init index 7612830103..b1f9e2e290 100644 --- a/package/network/services/dnsmasq/files/dnsmasq.init +++ b/package/network/services/dnsmasq/files/dnsmasq.init @@ -660,6 +660,12 @@ dnsmasq_start() append_bool "$cfg" dnsseccheckunsigned "--dnssec-check-unsigned" } + config_get addmac "$cfg" addmac 0 + [ "$addmac" != "0" ] && { + [ "$addmac" = "1" ] && addmac= + xappend "--add-mac${addmac:+="$addmac"}" + } + dhcp_option_add "$cfg" "" 0 xappend "--dhcp-broadcast=tag:needs-broadcast"
