+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.

++You may also specify whitelist entries for the upstream interface. Only igmp membership reports
++for explicitely whitelisted multicast groups will be sent out on the upstream interface. This
++is useful if you want to use multicast groups only between your downstream interfaces, like SSDP

+Subject: [PATCH 4/4] use monotic clock instead of time of day
+
+The time of day might chance e.g. by daylight savings time during the
+runtime, which causes timers to fire repeatedly for a long time.
