From 38cf8379b0bc991cda914c0a5c96d1dac3cff73b Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Sat, 19 May 2012 20:17:54 +0000 Subject: [PATCH] dnsmasq: add support for set: and tag: pairs On my network, I have a variety of machines and appliances, some of which need different configuration issues than the default options. For example: config host option name 'client' option mac '00:01:02:03:04:05' option ip '192.168.1.20' option tag 'acme' config tag acme option force '1' list dhcp_option 'option:router,192.168.1.253' list dhcp_option 'option:domain-name,acme.com' list dhcp_option 'option:domain-search,acme.com,redfish-solutions.com' which allows me to override the default router for my client's host, as well as its domain-name, and its domain-search. this causes the following config lines: dhcp-host=00:01:02:03:04:05,set:acme,192.168.1.20,client dhcp-option-force=tag:acme,option:router,192.168.1.253 dhcp-option-force=tag:acme,option:domain-name,acme.com dhcp-option-force=tag:acme,option:domain-search:acme.com,redfish-solutions.com This could be useful elsewhere, for instance, if you have an IP CCTV that you don't want to have a default-route, etc. Signed-off-by: Philip Prindeville SVN-Revision: 31815 --- package/dnsmasq/files/dnsmasq.init | 23 +++++++++++++++++++++-- 1 file changed, 21 insertions(+), 2 deletions(-) diff --git a/package/dnsmasq/files/dnsmasq.init b/package/dnsmasq/files/dnsmasq.init index 33fc177d06..f3d438e209 100644 --- a/package/dnsmasq/files/dnsmasq.init +++ b/package/dnsmasq/files/dnsmasq.init @@ -224,14 +224,32 @@ dhcp_host_add() { config_get name "$cfg" name config_get ip "$cfg" ip - [ -n "$ip" ] || [ -n "$name" ] || return 0 + [ -n "$ip" -o -n "$name" ] || return 0 macs="" config_get mac "$cfg" mac for m in $mac; do append macs "$m" ","; done [ -n "$macs" ] || return 0 - xappend "--dhcp-host=$macs${networkid:+,net:$networkid}${ip:+,$ip}${name:+,$name}" + config_get tag "$cfg" tag + + xappend "--dhcp-host=$macs${networkid:+,net:$networkid}${tag:+,set:$tag}${ip:+,$ip}${name:+,$name}" +} + +dhcp_tag_add() { + local cfg="$1" + + tag="$cfg" + + [ -n "$tag" ] || return 0 + + config_get_bool force "$cfg" force 0 + [ "$force" = "0" ] && force= + + config_get option "$cfg" dhcp_option + for o in $option; do + xappend "--dhcp-option${force:+-force}=tag:$tag,$o" + done } dhcp_mac_add() { @@ -435,6 +453,7 @@ start() { echo >> $CONFIGFILE config_foreach dhcp_boot_add boot config_foreach dhcp_mac_add mac + config_foreach dhcp_tag_add tag config_foreach dhcp_vendorclass_add vendorclass config_foreach dhcp_userclass_add userclass config_foreach dhcp_circuitid_add circuitid -- 2.30.2
