* 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: fix balanced default configFlorian Eckert2022-09-14
| | | | | | | The metrics and weight need to be the same. A 50% balanced would be require member policies of the same metric and weight value. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: add sleep to release ipset referenceFlorian Eckert2022-03-14
| | | | | | | | It turns out that under high system load, ipsets cannot be deleted. This is because there is still a reference in iptables. A short sleep should give the system time to clean this up. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* mwan3: Split ipsets into separate ipv4 and ipv6 setsFlorian Eckert2022-03-14
| | | | | | | | | | Nft does not directly support ipsets, nft sets must be used instead. The mwan3 uses ipsets for certain tasks. They can be combinded. So called an ipset of ipsets. This list type is not available in nft. So that mwan3 could be ported to nft in the feature, the ipset handling should be split. So we have for each ipset an iptables rule.

* 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>

* 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.
