| | | | | | | | Commit 7573880ac042c6e5c8d48b1ad83d357b5e02743b added support for 6rd attributes as a nested json data object which makes the attributes TUNNEL_ATTR_6RD_PREFIX and TUNNEL_ATTR_6RD_RELAY_PREFIX unused Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd: allow negative neighlocktime valuesAlin Năstac2017-08-172-3/+3
| | | | | | | | | When -1 is written in /proc/sys/net/ipv4/neigh/<iface>/locktime, kernel disables ARP trashing protection. A value of 0 does not completely disable this protection, a second ARP update being discarded if it is processed during the same jiffie as the first update.

* ubus: remove superfluous error check in netifd_add_dynamicHans Dedecker2017-06-171-5/+0
| | | | | | | | | | | | | | | | 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.

* iprule: Add option to suppress unspecific routing lookupsStefan Tomanek2017-06-113-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After applying this patch, policy routing rules can be employed that ignore parts of a routing table. The following config snippet ignores routing lookups from the specified main routing table yielding the default route, passing the lookup process on to the next rule (that might provide a special default route for marked packets): config rule option priority 10 # check main routing table first, but ignore default route result option lookup main option suppress_prefixlength 0 config rule option priority 11 # use special routing table for marked packets # (unless already consumed by previous rule) option mark 0xFF option lookup 100 The result is a ruleset like this (only visible using the full 'ip' binary): # ip rule 0: from all lookup local 10: from all lookup main suppress_prefixlength 0 11: from all fwmark 0xff lookup 100 32766: from all lookup main 32767: from all lookup default # Signed-off-by: Stefan Tomanek <stefan.tomanek@wertarbyte.de>

* netifd: propagate error code on netifd_reload()Alexandru Ardelean2017-04-055-8/+16
| | | | | | | | | | | | | | | 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.

* interface-ip: fix device name for IPv6 link-local DNS serverHans Dedecker2017-04-051-2/+3
| | | | | | | | | | Commit 235a02424c3ab1b59308895c4f00395dacf2557c adds support for IPv6 link-local DNS server by appending the device name; however the interface ifname parameter does not always contain the layer 3 device name (e.g it can hold the aliased interface name) Fix this by passing the device name of the referenced layer 3 device.

* system-linux: add VXLAN supportMatthias Schiffer2017-03-073-1/+181
| | | | | | | | | | | | 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.

* netifd: Add option to configure locktime for each deviceAlin Năstac2017-02-113-0/+33
| | | | | | | | | | | The UCI parameter neighlocktime allows to control the hardware address to IP mapping lock time in the IPv4 neighbour table. The IPv6 lock time was not set because it is not used at all in any kernel versions, hardware address override being controlled in this case by the override flag present in the NA packet.

* interface: add prefix assignment priority supportHans Dedecker2017-02-115-17/+52
| | | | | | | | | | | | | | | | | | | | | | | | | 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]
* device: add veth supportMatthias Schiffer2017-02-115-1/+337
| | | | | | | | | | | | | 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.

* netifd: Add sendredirects config supportDaniel Golle2017-01-103-0/+31
| | | | | | | | | | | | | | | | | | | | | | Setting /proc/sys/net/ipv4/conf/*/send_redirects is useful if a single layer-2 domain is shared among routed subnets. Sending redirects will prevents traffic from taking unnessesary detours through a gateway in cases where direct connectivity on layer 2 exists. This is commonly the case if an existing LAN infratructure with dump switches is used to additionally carry routing protocols like OLSR which are supported only by some nodes on the network. It's important to note that the default value for send_redirects differs for interface types (it's enabled on physical ethernet interfaces, but disabled e.g. on VLANs) due to olsrd changing /proc/sys/net/ipv4/conf/default/send_redirects during boot, thus the default differs also depending e.g. on the way an on-board switch is integrated on specific boards (as eth0 exists before olsrd is started, eth0.1 gets created by netifd later on...) Having a way to explicitely enable or disable send_redirects is thus desireable also to unify the default behaviour among different, but seemingly similar devices supported.

* proto: allow configuring deprecated static IPv6 addressesMatthias Schiffer2016-12-241-5/+14

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

* interface: Fix triggering of interface update eventHans Dedecker2016-11-043-8/+10
| | | | | | | | | | | | | | | | | In case the keep flag is set in proto_shell_update_link no interface update event is triggered when IPv4/6 addresses/routes/... are updated as the proto_event callback is not called due to keep being set. Unconditionally call the proto_event callback handler in proto_shell_update_link but let the proto_event callback handler; in this case interface_proto_event_cb, decide which actions need to be taken dependant on the interface state. In case the interface is already in the up state trigger an update event only if the interface updated flag actually indicates either an IP address/ route/data change; before interface update events were actually sent wihtout any parameter change.

* bridge: Don't use device name as bridge member nameHans Dedecker2016-11-041-7/+12
| | | | | | | | | | | The bridge name is a copy of the device name; but the device name can change which is the case when an aliased interface is used as bridge member.

* device: Drop device down event during device release if device gets active againHans Dedecker2016-09-261-0/+4
| | | | | | | | | | | | Fixes a race condition as the device can be active again; due to a device_claim; by the logic behind the set_state device type function. In this case the down event cannot be sent anymore as it would bring down the interface(s) referencing the device. This can be the case for an aliased device when the underlying device is switched during a reload; the alias_set_device function can add a new dependency on the new active device which will put the aliased device in active mode again as the aliased device is already claimed by the interface using it.
