* mwan3: make mwan3.user executableFlorian Eckert2022-12-19
| | | | | | | | | | | | | | | This is a fix for the the following change: https://github.com/openwrt/packages/commit/3d824ea288d907a31729c3629e884ea122c30da0 Before the change, it was only possible to execute a shell script. To remove this restriction, a binary or other script language can now also be used for 'mwan3.user'. Unfortunately, the old shell script was not executable for older mwan3 version. During a sysupgrade with config transfer, this 'mwan3.user' script could not be executed for newer mwan3 versions. To fix this, the calling script checks whether the 'mwan3.user' is executable, and if not, this executable bit is now set. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* mwan3: make it clearer who initiated the startFlorian Eckert2020-11-06
| | | | | | | | | It was somewhat opaque how the variable a is questioned. To show this better the variable is now a string and not a boolean. So you can see directly what should happen. With a boolean you always have to think about what it means when 0 or 1 is used. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: use procd for locking everywhereAaron Goodman2020-11-06
| | | | | | | | | | | | | | | | | | | Replace locks on /var/run/mwan3.lock with locks via procd. This fixes a deadlock issue where mwan3 stop would have a procd lock, but a hotplug script would have the /var/run/mwan3.lock Locking can be removed from mwan3rtmon since: 1) procd will have sent the KILL signal to the process during shutdown, so it will not add routes to already removed interfaces on mwan3 shutdown and 2) mwan3rtmon checks if an interface is active based on the mwan3_iface_in_<IFACE> entry in iptables, and the hotplug script always adds this before creating the route table and removes it before deleting the route table Fixes github issue #13704 (https://github.com/openwrt/packages/issues/13704)
* mwan3: reload unreachable/blackhole rules on hotplugAaron Goodman2020-11-06
| | | | | | | | | when the network procd service restarts, it flushes the ip rules. We need to add these rules back. Since hotplug events are triggered when the networks come back online, adding this call to the hotplug script is the most convenient place to refresh the rules.

| | | | | | | | | | | | | | | | | | | | | | improve startup and runtime performance by 1) moving common startup procedures out of hotplug script when called from mwan3 start 2) reducing calls to iptables to check status of rules 3) consolidating iptables updates and updating with iptables-restore 4) do not wait for kill if nothing was killed 5) running interface hotplug scripts in parallel 6) eliminate operations in hotplug script that check status on every single interface unnecessarily 7) consolidate how mwan3track makes hotplug calls 8) do not restart mwan3track on connected events This is a significant refactor, but should not result in any breaking changes or require users to update their configurations. version bump to 2.9.0 Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>

| | | | | | | | | With this change it is now possible to combine interface action events.

* 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: add custom address from ip tables to connected ipsetFlorian Eckert2018-10-23
| | | | | | | | | | | With the list param "rt_table_lookup" in the mwan3 section globals, it is now possible to add a additional routing table numbers which would get also parsed and will be added to the connected network. So mwan3 will treat them as they are directly connected to this device. This could be usefull if we use ipsec. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* net/mwan3: fix update on connected ip networksFlorian Eckert2018-05-30
| | | | | | | | | If an interface is not tracked by mwan3 or enabled and this interface is setup by netifd, then the connected ipset is not update by mwan3.

* 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.

* 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.

* 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>
