2016-02-01device: Support multicast config optionHans Dedecker

2015-11-04device: Don't process link events anymore in device user specific callback ↵Hans Dedecker
handlers Set link_state for all device types via the device_set_link API as all devices are registered in the device tree list making it possible to always get the device via device_get. The decice link state parameter will now actually reflect the corresponding kernel device carrier state in all cases. Before this change a vlan/macvlan device could still have link_state enabled if an interface was brought down; this was the case when the parent vlan/macvlan device was still enabled as the netlink link_state event would be dropped for vlan/macvlan devices due to keep_link_state in the function cb_rtnl_event.

2015-08-25bridge: Allow setting multicast_router optionLinus Lüssing
The multicast_router option of a bridge allows to control the forwarding behaviour of multicast packets independant of the listener state: * 0: Only forward if specific listener is present * 1 (default): Forward if specific listener or a multicast router was detected (currently only learned via query messages, no MRD support yet) * 2: Always forward any multicast traffic on this port Since MRD is not mandated you might end up with silent multicast routers (e.g. if your link has more than one multicast router; only one can become the selected, "noisy" querier). Here you might need a manual configuration option like the "multicast_router" option. Other scenarios where this can be useful are for instance: * Segmentation of IGMP/MLD domains together with ebtables * Dedicated bridge port for monitoring/debugging purposes Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue>
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>

2015-05-12netifd: Support for configurable default packet steering behaviorHans Dedecker
The default packet steering behavior can be configured via the parameter default_ps in the global section; the default value is true to keep backwards compatibility. Device packet steering (rps/xps) config can still be used to override the default behavior. This allows you to disable packet steering for all devices without the need to define a device config list which disables receive/transmit packet steering Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2014-06-11Add vlan 802.1q/802.1ad support as netifd devicesGioacchino Mazzurco
At moment netifd supports just 802.1q vlan, you can configure them using a concise but "hacky" syntax using an interface config section, with this patch netifd acquire the capability of configuring 802.1ad and 802.1q vlan using config device sections, so you can define a vlan device plus interface with something like this: config device 'test' option type '8021ad' option name 'test' option ifname 'eth0' option vid '1000' config interface 'testif' option ifname 'test' option proto 'none' option auto '1' old syntax for 802.1q keeps working so no retrocompatibility problems, to keep retrocompatibility means also that user must not use name/ifname like eth0.2 for devices declared with the new style because this would trigger the "old style" when interface config section is parsed Signed-off-by: Gioacchino Mazzurco <gmazzurco89@gmail.com>
