* system-linux: make encaplimit configurable for ip6 tunnels (FS#1501)Hans Dedecker2018-05-301-0/+7
| | | | | | | | | | | | | Make encapsulation limit of IP6 tunnels configurable for the ds-lite/map proto shell handlers as not all ISPs support the destination option header containing the tunnel encapsulation limit value as reported in FS#1501. The IP6 tunnel specific setting encaplimit is parsed as a nested json data object; setting it to ignore disables the insertion of the destination option header while a value from 0 till 255 sets the tunnel encapsulation limit accordingly in the destination option header.

* system-linux: add VXLAN supportMatthias Schiffer2017-03-071-0/+10
| | | | | | | | | | | | VXLAN shares many attributes with the tunnel devices, so it is implemented as a new tunnel type. The 'remote' attribute can be used for an unicast peer or a multicast group. The IANA-assigned port 4789 is used by default, instead of the non-standard port Linux defaults to.

* device: add veth supportMatthias Schiffer2017-02-111-0/+18
| | | | | | | | | | | | | The veth config code mostly handles the primary interface of a veth pair, the secondary interface is not explicitly referenced and will be found as an unrelated interface after the pair has been created. This doesn't only allow us to keep the veth code simple (and similar to existing device handlers), but will also avoid complicating handling unnecessarily in case the secondary interface is moved into another network namespace.

| | | | | | | | | | | Route proto support is usefull when using route distribution via a routing daemon. The route proto parameter can be specified via the route proto uci config parameter, it can hold a numerical value or the string values unspec, kernel, boot, static or a string present in /etc/iproute2/rt_protos.

* bridge: multicast: Export some parameters RFCs suggest to be tunableLinus Lüssing2016-03-071-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | RFCs suggest some parameters of IGMP and MLD to be configurable by the administrator. With this patch the following parameters are configurable: * robustness (default: 2) * query_interval (default: 12500 [125s]) * query_response_interval (default: 1000 [10s]) * last_member_interval (default: 100 [1s]) Depending on the size and nature of the network topology administrators might want to increase or decrease these parameters. netifd will take care of configuring any other parameters which are dependant on the ones above and set them according to the formulas provided in the RFCs. These parameters of the bridge are membership_interval, querier_interval, startup_query_interval, startup_query_count and last_member_count. RFCs allow setting three more parameters to be configurable: startup_query_interval, startup_query_count and last_member_count. However this patch does not export them, as they can be indirectly tuned via the given, exported four parameters, too. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue>

* bridge: allow setting hash_max valueLinus Lüssing2015-05-271-0/+1
| | | | | | | | | | | | If the number of entries in the MDB exceeds hash_max then the multicast snooping capabilities of the bridge are disabled automatically. The default value for hash_max is 512 which is already exceeded by some wireless community mesh networks. They need to be able to set a higher value.

* bridge: allow enabling or disabling the multicast querier independently of ↵Matthias Schiffer2015-03-231-0/+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 device ifindex overwrite when processing netlink event messagesHans Dedecker2014-11-191-0/+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>

| | | | | | | | | | | 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.

* netifd: Route type supportHans Dedecker2014-06-181-0/+1
| | | | | | | | 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/+13
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

* add bridge priority optionNiels Boehm2013-04-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [netifd] add bridge priority option Using the bridge priority (lower numbers are higher in the hierarchy), one can ensure that the router is chosen as root bridge in a setup with spanning tree protocol. For instance, one can set the priority of network lan to 32767, causing the router to win over all directly and indirectly connected nodes that have a default priority of 32768. The reason for doing that is that otherwise it has a default priority 32768 as well and any other connected node could win and get root bridge. In a home setup, those nodes are often desktop or laptop boxes and get switched off from time to time. As a consequence, root bridges vanish or new root bridges get chosen relatively often, resulting in frequent topology changes to the STP network. While the new topology has not settled, packets can get lost, causing noticeable interruptions of network traffic. Setting the router's bridge on a lower numbered priority (and thus higher in the selection hierarchy) solves the problem in the vast majority of the cases by ensuring that the device that is most likely powered on 24/7 gets chosen as root and prevents topology changes.
