* 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.

| | | | | | | | Use common function to toggle ip address in /var/state/mwan3. Change also to use toggle function and not set function. If ip address is often changed every change is saved to /var/state/mwan3. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* 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: add hotplug script for hidden self interface generationFlorian Eckert2017-08-10
| | | | | | | | | | | | | | Add new globals config section with option local_source. With this config option the self interface generation will be done now automatically on hotplug event. You can specify which interface (ip) sould be used for router traffic. To replace the self intereface in the config set local_source to "lan". The default option is none, so it will not change default behavior if a "self" interface is configured in the network section. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

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

| | | | | | | | | 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>

* net/mwan3: remove pid file use pgrep to get pidFlorian Eckert2017-05-12
| | | | | | | | | | | | | | | If mwan3track will not stop immediately after sending the kill signal, the clean_up handler will delete the pid file later while the new mwan3track is already running. This could result in a situation that mwan3track is running more then once because the old mwan3track service could not be killed, because the pid file is missing. Using pgrep to kill all mwan3track for the tracked interface and not using pid file should fix this issue. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

It will also generate an additional down event when he notice does his tracking interface is offline. Mwan3track will now be informed by a signal (trap) USR1 during down event that the interface is already down. An additional down event will not be generated.

* net/mwan3: add failure and recovery intervalFlorian Eckert2017-03-27
| | | | | | | | | | | | | If mwan3track detects a failure the interval check will change to "failure_interval" value until this interface is declared "offline". After interface gets "offline" normal "interval" value is used again. If interface ping is successful again "recovery_interval" value is used until interface is declared "online" again. Using the different intervals will accelerate the wan line detections on failure and recovery. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
