* qosify: add package for simple qos based on ebpf+cakeFelix Fietkau2021-11-01
| | | | | | | | | | | | | | qosify is simple daemon for setting up and managing CAKE along with a custom eBPF based classifier that sets DSCP fields of packets. It is configured via UCI and it supports the following features: - simple TCP/UDP port based mapping - IP address based mapping - priority boosting based on average packet size - bulk flow detection based on number of packets per second - dynamically add IP entries with timeout Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ltq-vdsl-app: add error vector counters to the ubus metricsAndre Heider2021-10-21
| | | | | | | | | | | | | | | These are useful stats to debug vector related line deteriorations, see [0]. Example output: "erb": { "sent": 169925, "discarded": 0 } [0] https://forum.openwrt.org/t/vectoring-on-lantiq-vrx200-vr9-missing-callback-for-sending-error-samples/104046 Signed-off-by: Andre Heider <a.heider@gmail.com>
* ltq-vdsl-app: prepare for multiple mei ioctlsAndre Heider2021-10-21
| | | | | | | | | | | | Refactor so that the outer function opens and closes the mei fd and passes it around, just as with the main fd. That also allows us to use the IOCTL macro in get_vector_status() and clean up accordingly. Switch to AUTORELEASE while at it. Signed-off-by: Andre Heider <a.heider@gmail.com>

* ltq-vdsl/ltq-vdsl-app: clean up configure argsJan Hoffmann2021-08-21
| | | | | | | | | | | | | | | | | | | | | The userspace application now uses the model=full option to match the configuration of the kernel module. The source no longer contains SOAP support, which was the primary reason to build only typical instead of full before. This makes several CLI commands, which were already supported in the kernel module, available in the userspace application. For example, this includes bbsg which allows to get information about VDSL2 bands. Some previously applied build options were redundant. Disabling ADSL MIB support is unnecessary, as it only applies to Danube. ADSL LED support is no longer included in the source. ReTx counters are already included with model type full. This increases the size of the userspace application by approximately 15 kB (uncompressed). The kernel module does not change at all. Signed-off-by: Jan Hoffmann <jan@3e8.eu>

Since the MEI driver doesn't provide an autogenerated header with compile flags, the flags are hardcoded for the vdsl app. Set them for the MEI driver as well, to indicate a relation to the values used for the vdsl app and to be not surprised by a changed default in case the MEI driver gets updated.

This helps in setups where a wan ip or prefix changes. This corresponse to setting up an vxlan tunnel with: proto vxlan6: # ip link add vx0 type vxlan id ID local :: ... proto vxlan: # ip link add vx0 type vxlan id ID local 0.0.0.0 ... While it is possible to not specify a source ip at all, the kernel will default to setting up a ipv4 tunnel. The kernel will take any hint from source and peer ips to figure out, what tunnel type to use. To make sure we setup an ipv6 tunnel for proto vxlan6, this workaround is needed. This will not change the behaviour of currently working configurations. However this will allow former broken configurations, namely those not specifying both a source address and tunnel interface, to setup a tunnel interface. Previously those configurations weren't reporting an error and were stueck in a setup loop like in Bug FS#3426. This change lifts the currently very strict behaviour and should fix the following bug: Fixes: FS#3426 Ref: https://bugs.openwrt.org/index.php?do=details&task_id=3426 Signed-off-by: Johannes Kimmel <fff@bareminimum.eu>
