* 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: don't call rpcd on 'mwan3 interfaces'Aaron Goodman2020-11-16
| | | | | | | Allow `mwan3 interfaces` to get uptime via an internal function and thus remove the dependency on rpcd for `mwan3 interface` calls. Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>

* 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: 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: use procd for mwan3rtmon and mwan3trackAaron Goodman2020-10-16
| | | | | | | | | | | start all mwan3mon and mwan3track instances on mwan3 start if an interface is down when mwan3track starts, it waits for a signal from the hotplug script to start procd can then handle stopping all of the scripts when mwan3 is halted Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>

* 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>

* treewide: replace `which` with `command -v`Paul Spooren2020-08-09
| | | | | | | | | | Fix shellcheck SC2230 > which is non-standard. Use builtin 'command -v' instead. Once applied to everything concerning OpenWrt we can disable the busybox feature `which` and save 3.8kB. Signed-off-by: Paul Spooren <mail@aparcar.org>

* mwan3: Fix mwan3 start not doing anythingMichiel Blokzijl2020-07-03
| | | | | | | | | Due to a missing config load function call, mwan3 start runs ifup for an empty list of interfaces, thus not calling ifup at all. This commit introduces the missing config_load call. Signed-off-by: Michiel Blokzijl <code@m01.eu>

* 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>
