* mwan3: reset score to up+down on connectedFlorian Eckert2023-05-08
| | | | | | | | | | Set the score value to the maximum value when the connected function is called. The same happens with a disconnected event, the score value is there set to zero.

* mwan3: refactoring mwan3track action handlingFlorian Eckert2023-05-08
| | | | | | | | Refactoring the score handling, so that only one action could take place during run. The behaviour should be more comprehensible, since several score actions are not processed at the same time. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: only send disconnected event if interface was connected beforeFlorian Eckert2022-10-17
| | | | | | | | Up to now on every interface down event a mwan3 disconnected event was send. This is wrong because if the interface was never connected, then a disconnected event should not get generated. This commit fixes this bug. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: add connecting and disconnecting event to mwan3trackFlorian Eckert2021-03-16
| | | | | | | | | | | | | If the interface goes into failure state (is disconnecting) then with this change one hotplug.d event is generated. The same is true for the recovery state (is connecting), when the interface comes back from a failure state. In both cases, a hotplug.d event for the iface is triggered. Once with the $ACTION=disconnecting and once for the $ACTION=connecting. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: disable DNS lookups for ping checksFlorian Eckert2021-03-01
| | | | | | | | | | | | | | | | | By default, ping does a reverse DNS of the IP that you are pinging. When you have a network issue (such as when a link has just gone down and you haven't yet marked it down), this lookup can cause failures on tests for links that are still good. This option only works for iputils ping. For busybox the option is not evaluated, but it is accepted without throwing an error.

* mwan3: add back support for iputils pingAaron Goodman2020-10-16
| | | | | | | With the new wrapper code, we can override the broken binding behavior of iputils ping v20101006. Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* mwan3: add "use" function to mwan3 utilsAaron Goodman2020-10-16
| | | | | | | | | | | | | | | Use "mwan3 use" to wrap a command with interface bindings so that you can avoid the mwan3 rules and test behavior on a specific interface. eg "mwan3 use wan ping -c1 1.1.1.1" Additional binding arguments to the command will have their system calls intercepted and ignored. eg "mwan3 use wan ping -c1 -I tun0 1.1.1.1" will use the device associated with "wan", rather than "tun0".

* mwan3: use helper library for mwan3trackAaron Goodman2020-10-16
| | | | | | | | | | | | | | | | | Rather than using a special mwan3 user to manage mwan3track's tracking packets, this commit implements a small helper library to bind to device and to set a fwmark so that the tracking packets can be routed out of the correct interface. This provides a consistent method for binding to a device rather than relying on various packages potentially buggy implementations. For example: #8139 and #12836 This helper issue also allows for more tracking methods to be added even if they do not have a command line option to bind to device, such as iperf3 (eg #13050).

* mwan3: improve startup performance; version 2.9.0Aaron Goodman2020-08-17
| | | | | | | | | | | | | | | | | | | | | | 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>

* mwan3: force busybox pingAaron Goodman2020-05-22
| | | | | | | | | | | | | | | openwrt 19.07 uses iputils 20101006-1 This ancient version of iputils has a bug where the -I option is not respected. https://github.com/iputils/iputils/issues/55 https://github.com/iputils/iputils/issues/56 https://bugs.openwrt.org/index.php?do=details&task_id=1486 Thus, we should force using busybox ping at "/bin/ping" until the iputils version gets an upgrade in the next major release Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* mwan3: Don't use /128 address for ping sourceBrian J. Murrell2020-04-30
| | | | | | | | An interface can have both a /64 and a /128 from a provider. In such a case, use the address from the /64 to do the ping check, not the /128. Signed-off-by: Brian J. Murrell <brian@interlinx.bc.ca>

| | | | | | | | | | Pinging IPv6 hosts using an interface as a source specifier seems troublesome. See https://bugs.openwrt.org/index.php?do=details&task_id=2897 for more detail. Use the desired source interface's IP address instead. Signed-off-by: Brian J. Murrell <brian@interlinx.bc.ca>

* 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>
