* mwan3: fix logical/typo bug in mwan3rtmonChen Minqiang2019-03-22
| | | | | | | | This bug was introduced since dd206b7d0bc4a7de739b6dbccbac5b5ffcae9024 mwan3_remon_ipv4 and mwan3_remon_ipv6 is command to run not a variable I add some comments on them hopefully people will notice it Signed-off-by: Chen Minqiang <ptpt52@gmail.com>
* mwan3: fix disconnected event generation in mwan3trackFlorian Eckert2019-02-27
| | | | | | | | | | Before this change two disconnected events were generated. This is wrong! The disconnected event is impliciet generated by the hotplug script on ifdown event. The mwan3track script is notified by a USR1 signal which generates the disconnectd event. The additional "disconnectd" event on ifdown is not required. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* net/mwan3: add online_metric for local_source noneFlorian Eckert2018-10-23
| | | | | | | | | | | | | | | | | | | | | If we set the option "local_source" in the globals mwan3 section to "none", traffic generated by the router it self will always use the default route from the wan interface with the lowest metric. If this interface is down the router traffic still uses the connection with the lowest metric but this is disconnected. Load balancing and failover from the lan site is still possible. Only router generated traffic is not load balanced and could not use failover. To solve this issue with router initiated traffic add the additional option "online_metric" to the mwan3 interface section. If the interface is connected then this lower "online metric" is set in the default routing table. With this change we have at least a failover with router initiated traffic.

* net/mwan3: deviate max interface value from mmx_mask valueFlorian Eckert2018-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need always three of the firewall mask value for * default routing table * blackhole * unreachable the other will be used for the interfaces. * If we have set the mmx_mask to max 0xFF00 (8 bit set) we could use max 252 interfaces. * If we have set the mmx_mask to min 0x0E00 (3 bit set) we could use max 4 interfaces. Only the ones are counting from the firewall mask value. Minimal three firewall mask bit vaules must be set. Maximal eight firewall mask bit vaules could be set.

* mwan3: fix interface-bound traffic when interface is offlineMarcin Jurkowski2017-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixed what 6d99b602 was supposed to fix without affecting interface-bound traffic. Before 6d99b602 interface-bound traffic was working normally as long as at least one interface was online. However when the last interface went offline, it was impossible to ping and such state was unrecoverable. Commit 6d99b602 fixed unrecoverable offline state problem (it was possible to ping -I iface) but messed inteface-bound traffic. Traffic with interface source address was not working if the interface was in "offline" state, even if another interface was online. The problem was caused by an inconsistent "offline" interface state: iptables-related rules were kept while routing table and policy were deleted. The idea behind this commit is to: 1. Keep all the rules for each interface (iptables, routing table, policy) regardless of its state. This ensures consistency, 2. Make interface state hotplug events affect only iptables' mwan3_policy_* rules. Interface-related iptables, routing table and policy is removed only when mwan3 is manually stopped. To make such changes possible, it's necessary to change the way mwan3_policy_* rule generator keeps track of interface state hotplug events. Until now, it checked for the existence of custom interface-related routing table (table id 1, 2, 3, ...). Clearly we can no longer rely on that so each interface state is stored explicitly in file.

* mwan3: fix bugs introduced in 815e83d4Marcin Jurkowski2017-08-17
| | | | | | | | | | Fixes the following bugs introduced in commit 815e83d4: - hotplug: invalid parameter order when initial interface state is "online", mwan3track expects initial state to be the third argument - hotplug: missing source ip address when initial interface state is "offline" - mwan3track: source ip address should be the fourth argument Signed-off-by: Marcin Jurkowski <marcin1j@gmail.com>

* net/mwan3: expand ubus to show when last mwan3track check was doneFlorian Eckert2017-08-10
| | | | | | | To know how old the ubus output is, add an age parameter which indicats how old the check informations on the interface are. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* net/mwan3: on startup mark interface online only if track_ip are reachableFlorian Eckert2017-08-10
| | | | | | | | | | | | | | | | Add new interface config option "inital_state". If interface comeing up the first time(mwan3 start, boot), there are now two option for interface behaviour: - online (default as is now) Set up interface regardless wether tracking ip are reachable or not. - offline Set up interface first to ping tracking ip and if they are reachable set up the interface completely.

* net/mwan3: fix ping issue if last interface recovers from failureFlorian Eckert2017-08-10
| | | | | | | | | | | Even though error was fixed the interface checks still fails, if last_resort was set to blackhole or unreachable. To fix this issue do not remove failure interface from iptables change on down event. Reported-by: Colby Whitney <colby.whitney@luxul.com> Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* net/mwan3: fix mwan3track kill executionFlorian Eckert2017-08-10
| | | | | | | | | If two interface have the same prefix "wan" for example "wan" and "wan1" pgrep returns the PID for wan1 also "pgrep -f mwan3track wan". Before this fix "wan1" was also killed! This is not what we want. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* mwan3: support various interface tracking methodsMarcin Jurkowski2017-08-02
| | | | | | | | | | | | Adds support for interface tracking using either ping, arping or httping. This allows to track interface status on networks with filtered ICMP traffic or simply to monitor data link layer etc. To facilitate binding to a specified interface its IP address is passed as a new mwan3track parameter. It's currently required by httping and possibly by other tools that may be added in the future. Signed-off-by: Marcin Jurkowski <marcin1j@gmail.com>
