2015-08-25bridge: Allow setting multicast_to_unicast optionLinus Lüssing
With this patch the multicast_to_unicast feature can be disabled for all wireless interfaces via an according option on the uci bridge interface. This patch also exports the setting information to wireless handler scripts. The hostapd script will need that information to determine whether to enable or disable ap-isolation, for instance.

2015-08-25bridge: Fix multicast_to_unicast feature by hairpin+isolateLinus Lüssing
All IGMP and MLD versions suffer from a specific limitation (from a snooping switch perspective): Report suppression. Once a listener hears an IGMPv2/3 or MLDv1 report for the same group itself participates in then it might (if this listener is an IGMPv3 or MLDv2 listener) or will (if this is an IGMPv1/2 or MLDv1 listener) refrain from sending its own report. Therefore we might currently miss such surpressing listeners as they won't receive the multicast packet with the mangled, unicasted destination. Fixing this by first isolating the STAs and giving the bridge more control over traffic forwarding. E.g. refraining to forward listener reports to other STAs. For broadcast and unicast traffic to an STA on the same AP, the hairpin feature of the bridge will reflect such traffic back to the AP interface. However, if the AP interface is actually configured to isolate STAs, then hairpin is kept disabled. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue>
2015-05-23proto-shell: allow running protocols without proto_task.Yousong Zhou
Adds a new config parameter "no-proto-task" for noting that no proto_task will be running for this protocol type. This is required since then change in commit "d0dcf74 proto-shell: retry setup if the proto handler script quits without changing the state or starting a process". The change is mainly for protocols like xl2tpd in which control commands are sent to another daemon xl2tpd to start L2TP negotiation and pppd process who is not under netifd's control as proto_task as is the case in other ppp related protocols like pppoe, pptp, etc. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
2015-04-03netifd: Interface last error supportHans Dedecker
Adds interface last error support which preserves the last reported error reported by the protocol handler till the interface is up; e.g. survives network reload and interface restarts. This is mainly usefull for tracking down why an interface fails to establish; eg auth failure/traffic limit for PPP interfaces Protocol handlers register last error support by setting lasterror=1 in the proto_init function Signed-off-by: Johan Peeters <johan.peeters111@gmail.com> Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2014-12-08Enable callers to pass the source IP of an IPv4 route when usingKristian Evensen
proto_add_ipv4_route(). This is useful with for example DHCP in a multihomed scenario, as it provides an easy way to match default routes with the correct IP address. One use case for this are applications that monitor the state of the WAN port, and the WAN port is assigned multiple addresses. Signed-off-by: Kristian Evensen <kristian.evensen at gmail.com>
