Subject: [PATCH] Restrict igmp reports for downstream interfaces (wrt #2833339)
atm all igmp membership reports are forwarded to the upstream interface.
Unfortunately some ISP Providers restrict some multicast groups (esp. those
that are defined as local link groups and that are not supposed to be
forwarded to the wan, i.e 224.0.0.0/24). Therefore there should be some
kind of black oder whitelisting.
As whitelisting can be accomplished quite easy I wrote a litte patch, which
is attached to this request.

+.B whitelist
+.I networkaddr
+.RS
+Defines a whitelist for multicast groups. The network address must be in the following
+format 'a.b.c.d/n'. If you want to allow one single group use a network mask of /32,
+i.e. 'a.b.c.d/32'.
+
+By default all multicast groups are allowed on any downstream interface. If at least one
+whitelist entry is defined, all igmp membership reports for not explicitly whitelisted
+multicast groups will be ignored and therefore not be served by igmpproxy. This is especially
+useful, if your provider does only allow a predefined set of multicast groups. These whitelists
+are only obeyed by igmpproxy itself, they won't prevent any other igmp client running on the
+same machine as igmpproxy from requesting 'unallowed' multicast groups.
+
+You may specify as many whitelist entries as needed. Although you should keep it as simple as
+possible, as this list is parsed for every membership report and therefore this increases igmp
+response times. Often used or large groups should be defined first, as parsing ends as soon as
+a group matches an entry.

Subject: [PATCH] Restrict igmp reports forwarding to upstream interface
Utilize the new "whitelist" keyword also on the upstream interface definition.
If specified then only whitelisted multicast groups will be forwarded upstream.
This can be used to avoid publishing private multicast groups to the world,
e.g. SSDP from a UPnP server on the internal network.
