* mwan3: support latest iputils pingAaron Goodman2020-11-16
| | | | | | | | | | | iputils upstream changed build params with version s20200821 Latest OpenWRT iputils ping now appears to report the openwrt version tag, rather than iputils date tag This commit sends a test ping to localhost to evaluate the capabilities of iputils ping.

* 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. Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* mwan3: fix boundaryFlorian Eckert2020-11-06
| | | | | | | | he line is too long. For the future it is better to split it into several lines and make it more clearly arranged. In case of a future change, not the whole line will be marked as a change. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: use common makefile install wrappersFlorian Eckert2020-11-06

| | | | | | | | | - support trailing route space from iproute2 - add routes even when iface is down - fix source_routing argument check - add quotes in logging to better detect issues with trailing spaces Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* mwan3: fix reload handlingFlorian Eckert2020-10-23

* 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". Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* 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).

| | | | | | | | | | | 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: fix bug when one interface is a prefix of anotherAaron Goodman2020-10-16

| | | | | | | | | | | | | | | | | | handle creation of routing tables in mwan3rtmon to avoid race conditions and potentially missing routes handle ipv6 routes that have expiry update directly connected ipset when routes are added or deleted add fall through rules so that the default routing table is not used if no rule in the interface-specific routing table matches add option to comply with mwan3 source based routing get default route parameters from main routing table 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>
* mwan3: use ip monitor route to detect routing changesAaron Goodman2020-08-15
| | | | | | | | | | | use only committed uci changes for updating routing table use functions.sh functions rather than uci command line tool to find interfaces for routing table. consolidate rtmon_ipv4 and rtmon_ipv6 functions into a single function Signed-off-by: Aaron Goodman <aaronjg@stanford.edu>
* treewide: replace `which` with `command -v`Paul Spooren2020-08-09

* mwan3: revert: also cleanup lock on mwan3 stopFlorian Eckert2020-07-28
| | | | | | | | | | | | This reverts commit cde2a77ed3b3b0df9e693e121dccdc97ef163156. Applying this change has shown that it is even quicker to provoke the race condtition on simultan mwan3 commands execution. By reversing the change we have the same behaviour as before. But the race condition on mwan3 execute at the same time still exists. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* mwan3: fix race condition on mwan3 restartFlorian Eckert2020-07-28
