* bridge: allow enabling or disabling the multicast querier independently of ↵Matthias Schiffer2015-03-231-1/+1
| | | | | | | | | | | | | | IGMP snooping In larger networks, especially big batman-adv meshes, it may be desirable to enable IGMP snooping on every bridge without enabling the multicast querier to specifically put the querier on a well-connected node. This patch adds a new UCI option 'multicast_querier' for bridges which allows this. The default is still the value of the 'igmp_snooping' option to maintain backwards compatiblity.

* netifd: Fix restore of original device settingsHans Dedecker2014-12-081-1/+2
| | | | | | | | Don't restore original device settings based on the device settings flags in system_if_down as device flags are already reset when the device config is deleted. Therefore move the masking of the relevant original device settings to system_if_up. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd v2: Fix source routing for IPv4Kristian Evensen2014-11-271-2/+6
| | | | | | | | | | | | | | | | | According to the OpenWRT Network documentation for route, the 'source' option is "The preferred source address when sending to destinations covered by the target". However, netifd currently stores this value in RTA_SRC on NEWROUTE/DELROUTE. RTA_SRC is not used by kernel when handling NEWROUTE nor DELROUTE for IPv4 routes. When adding a new IPv4 route, the source is stored in RTA_PREFSRC and the option works as specified in documentation. For IPv6, the address is still stored in RTA_SRC as to not break source-destination routing for IPv6. v2: Limit patch to IPv4, to prevent breaking IPv6 configurations (thanks Steven Barth) Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com>

* netifd: Remove superfluous system_if_resolve callsHans Dedecker2014-11-191-10/+2
| | | | | | | | Don't resolve the ifindex of the parent device again when adding vlandev and macvlan devices as the ifindex has already been resolved. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd: Fix device ifindex overwrite when processing netlink event messagesHans Dedecker2014-11-191-7/+2
| | | | | | | | | | | When a device with the same name is deleted and created again in the kernel the ifindex changes. A race condition will occur when netlink event messages linked to the old device are processed and will thus overwrite the correct ifindex of the new device. Further make sure a valid ifindex is in place for both external and internal devices when setting the state to enabled. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd: Read current link state when processing netlink eventHans Dedecker2014-10-241-6/+13
| | | | | | | | | | | | | | | | | Netifd commit b2dcb02570939d98b92c7c55db1c328693a5d52a introduces a race condition resulting into infinite toggling interfaces (eg static interfaces with linksensing enabled, vlan interfaces with proto none (#18106)) when linksensing is enabled resulting into a crash. As netlink event messages will be queued on the netlink event socket the included lower up interface flag will not always represent the current link state when netifd processes the netlink messages; by reading the current link state when a netlink event message is parsed the correct info is passed to the device layer. This will avoid continuous interface toggling (down/up) triggered by link state changes based on outdated netlink interface info. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: IPIP tunnel supportHans Dedecker2014-10-021-29/+82
| | | | | | | | | | | | | | Adds IPIP tunnel support to netifd. Following IPIP tunnel parameters can be configured : -peeraddr (IPv4 remote address) -ipaddr (IPv4 local address) -mtu (IPIP tunnel mtu) -ttl (time to live of encapsulting packets) -tos (type of service either inherit (outer header inherits the value of the inner header) or hex value) -df (don't fragment flag of encapsulating packets) -tunlink (bind tunnel to this interface) Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

| | | | | | | | | | | Do not treat RT_TABLE_MAIN as RT_TABLE_UNSPEC in system_resolve_rt_table() in order to allow ip rules with lookup main to work as expected. Provide a new function system_is_default_rt_table() to allow calling code to specifically test for RT_TABLE_MAIN, this is going to be needed for the backwards compatible handling of the table attribute in route objects.

| | | | | | | | Patch adds route type support in netifd by means of the route parameter type.

* Add vlan 802.1q/802.1ad support as netifd devicesGioacchino Mazzurco2014-06-111-0/+77
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
