From b1217c88c3566c1bd726bce9203da591af564bcf Mon Sep 17 00:00:00 2001 From: Hannu Nyman Date: Thu, 5 Nov 2015 10:54:33 +0200 Subject: luci-mod-admin-full: limit interface name length to 15 chars Limit the name of a new interface to 15 characters. Add a note about the maximum length and the automatic protocol/bridge prefixes (br-, 6in4-, pppoe- etc.). Reference to: https://dev.openwrt.org/ticket/20380 https://github.com/openwrt/luci/issues/507 There is a 15 character limit to the "real" interface name, enforced both in the firewall and dnsmasq. The real interface name includes the possible prefix "br-", "6in4-" etc. Example of an error: interface name `br-lan_protected' must be shorter than IFNAMSIZ (15) Signed-off-by: Hannu Nyman --- .../luasrc/model/cbi/admin_network/iface_add.lua | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'modules/luci-mod-admin-full/luasrc') diff --git a/modules/luci-mod-admin-full/luasrc/model/cbi/admin_network/iface_add.lua b/modules/luci-mod-admin-full/luasrc/model/cbi/admin_network/iface_add.lua index da1e140de..e48e3b4bd 100644 --- a/modules/luci-mod-admin-full/luasrc/model/cbi/admin_network/iface_add.lua +++ b/modules/luci-mod-admin-full/luasrc/model/cbi/admin_network/iface_add.lua @@ -17,7 +17,12 @@ newnet = m:field(Value, "_netname", translate("Name of the new interface"), newnet:depends("_attach", "") newnet.default = arg[1] and "net_" .. arg[1]:gsub("[^%w_]+", "_") -newnet.datatype = "uciname" +newnet.datatype = "and(uciname,maxlength(15))" + +advice = m:field(DummyValue, "d1", translate("Note: interface name length"), + translate("Maximum length of the name is 15 characters including " .. + "the automatic protocol/bridge prefix (br-, 6in4-, pppoe- etc.)" + )) newproto = m:field(ListValue, "_netproto", translate("Protocol of the new interface")) -- cgit v1.2.3
