* interface-ip: add support for excluding interfaces in host route lookupFelix Fietkau2022-05-191-1/+2
| | | | | | | | When adding host routes needed for an interface to communicate, it may be necessary to skip the interface itself, in case it provides a default route. This helps with avoiding accidental loops Signed-off-by: Felix Fietkau <nbd@nbd.name>

* add basic support for jail network namespacesDaniel Golle2020-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare netifd for handling procd service jails having their own network namespace. Intefaces having the jail attribute will only be brought inside the jail's network namespace by procd calling the newly introduced ubus method 'netns_updown'. Currently proto 'static' is supported and configuration changes are not yet being handled (ie. you'll have to restart the jailed service for changes to take effect). Example /etc/config/network snippet: config device 'veth0' option type 'veth' option name 'vhost0' option peer_name 'virt0' config interface 'virt' option type 'bridge' list ifname 'vhost0' option proto 'static' option ipaddr '10.0.0.1' option netmask '255.255.255.0' config interface 'virt0' option ifname 'virt0' option proto 'static' option ipaddr '10.0.0.2' option netmask '255.255.255.0' option gateway '10.0.0.1' option dns '10.0.0.1' option jail 'transmission' Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* interface: add neighbor config supportmeurisa2019-04-151-1/+19
| | | | | | | | | | | | | | | | | | The neighbor or neighbor6 network section makes neighbours configurable via UCI or proto shell handlers. It allows to install neighbor proxy entries or static neighbor entries The neighbor or neighbor6 section has the following types: interface : declares the logical OpenWrt interface ipaddr : the ip address of the neighbor mac : the mac address of the neighbor proxy : specifies whether the neighbor ia a proxy entry (can be 1 or 0) router : specifies whether the neighbor is a router (can be 1 or 0) Signed-off-by: Alexander Meuris <meurisalexander@gmail.com> Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* interface: add prefix assignment priority supportHans Dedecker2017-02-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In case of prefix delegation prefixes are assigned to one or more configured downstream interfaces. The delegated prefix length in combination with the assignment length of the downstream interfaces determines the number of subnets which can be allocated from the delegated prefix. The interface ip6weight parameter allows to prioritize the allocation of subnets to interfaces in case of multiple configured downstream interfaces. The order of interface prefix assignment from a delegated prefix is based on the following parameters: - Primary key is prefix assignment based on the configured interface ip6hint - Secondary key is the requested downstream interface prefix length, interfaces configured with the smallest ip6hint will be assigned first - Third key is the assigned interface ip6weight in case of equal prefix assignment length; interfaces having the highest ip6weight will be assigned first - Finally the alphabetical order of the interfaces in case of equal ip6weight Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> [cleanup]
* interface-ip: route proto config support (FS#170)Hans Dedecker2017-01-251-2/+3
| | | | | | | | | | | 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.

* interface-ip: fix subnet route handlingFelix Fietkau2015-12-151-0/+2
| | | | | | | | | | | | When the kernel subnet route has to be replaced, the cleanup call needs to match the properties of the replacement route exactly, mainly the metric and the routing table. Fix handling this by embedding the device_route for the subnet in the device_addr struct and using it in the cleanup path. This fixes issues on config reload with changes to the routing table Signed-off-by: Felix Fietkau <nbd@openwrt.org>

* netifd: Make interface identifier of delegated IPv6 address configurableHans Dedecker2015-01-191-0/+1
| | | | | | | | | | | | | The ip6ifaceid UCI interface parameter makes the interface identifier of the delegated IPv6 address configurable. The parameter can have the following values: eui64 : Interface identifier is generated from the interface's MAC address random : Interface identifier is generated randomly fixed value : Interface identifier is a fixed value (eg ::1:2) The latter is the default value with a fixed value of ::1 for backwards compatibility Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> Signed-off-by: Joeri Barbarien <joeri.barbarien@gmail.com>
* netifd: Route type supportHans Dedecker2014-06-181-0/+4
| | | | | | | | Patch adds route type support in netifd by means of the route parameter type. By default the route type was unicast; the parameter adss support for local/broadcast/multicast/unicast routes which will be put into the appropriate routing table. If route type parameter is unset the route type will be unicast as before. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
