2020-04-14interface: allow renaming interface when moving to jail netnsDaniel Golle
Introduce jail_ifname option to define the name of a Linux network interface when moved into a jail's network namespace. This is useful for containers which expect the network interface to have a specific name (eg. 'host0' in case of systemd). While at it, clean-up and fix bugs in jail interface up/down routines.

2020-01-18add basic support for jail network namespacesDaniel Golle
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>

2019-04-15interface: add neighbor config supportmeurisa
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>

2017-06-17ubus: remove superfluous error check in netifd_add_dynamicHans Dedecker
Check for main device and main device having default config for a dynamic interface was orginally added in commit 266d92dd83bd5bfe520f3e2838794bf9bb827c07 with as purpose to set the device config. The latter was later removed in commit 4bf89afc22b43d5bd155d32d3998348a77179c1a which makes the device checks superfluous. Also not all interfaces have a main device (eg tunnel interfaces) resulting into netifd_add_dynamic returning an error code when such interfaces are added. As an example 6rd interfaces dynamically added by the DHCP script the log messages are cluttered with the trace 'wan (7803): Command failed: Unknown error' after each DHCP renew.

2017-04-22ubus: add interface method to trigger renew eventMatthias Schiffer
Not all topology or connectivity changes may be detected by netifd, depending on the underlying technology (e.g. VPN software); this adds a way to explicitly trigger a renew. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> Acked-by: Hans Dedecker <dedeckeh@gmail.com>
2017-04-05netifd: propagate error code on netifd_reload()Alexandru Ardelean
The context is that we generate some of the UCI config for netifd via scripts/programs. Every once in a while, there's a goof when doing that UCI generation, and netifd prints out the error at stderr, but returns 0 (success) err-code. This change will fail the ubus call if UCI config is invalid or missing for /etc/config/network.

2017-02-11interface: add prefix assignment priority supportHans Dedecker
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]

2017-01-25interface-ip: route proto config support (FS#170)Hans Dedecker
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.

2016-12-12ubus: Display the IPv6 prefix assigned addressHans Dedecker

2016-11-22ubus: Use device_find to find a device when displaying device infoHans Dedecker
Replace device_get by device_find in netifd_dev_status as device_get will fail to find the device if it's created via config as an aliased vlan device in dotted notation (eg @iface.200). In such case get_vlan_device_chain will figure out the layer3 device but get_vlan_device will not find the vlan device in the dependency list of the layer 3 device as it has been created as a dependency of the aliased device.

2016-09-14interface-ip: DNS name server sorting support in resolv.conf.autoHans Dedecker
Interface name servers when being written to resolv.conf.auto are sorted based on the following parameters: -Primary sorting key is interface dns_metric; name servers having lowest interface dns_metric are listed first -Secondary sorting key is interface metric; in case of equal interface dns_metric name servers having lowest interface metric are listed first -Finally alphabetical order of the interface names in case of equal interface dns_metric and metric In case the resolver queries the multiple servers in the order listed; sorting is usefull in the following scenarios : -Name resolving over a main and backup interface -Assign priority to IPv6 name servers over IPv4 or vice versa Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2014-06-18netifd: Route type supportHans Dedecker
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>

2014-04-24netifd: Mark interface as dynamic after it has been added in the interface listHans Dedecker
Adding an interface in the interface list in case of a config update will override the node version of the old interface and thus overriding the dynamic interface marker. In case of config update interface_set_dynamic is done on an invalid interface pointer as the new interface pointer has been freed. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
