A channel change request from RRM while a reload_config is in progress cause the new CSA attempt fail. AP updated the UCI no matter if the CSA attempt failed or passed. This leads to the AP not re-trying the CSA again. Furthermore another issue is seen when an invalid channel/BW combination is configured. Solution is to update the Bandwidth as per channel change request is made via CSA. Example: BW already configured for 40MHz, and then the channel change attempt is made to 165. The channel change code takes care of downgrading the BW to 20MHz while sending the request down to the driver, but did not update the same in the UCI config. UCI config reads as 165/40. A reloadconfig thereafter causes this invalid combination 165/40 attempt which leads to radio stay disabled. Signed-off-by: ravi vaishnav <ravi.vaishnav@netexperience.com>
Setting up your build machine
Requires a recent linux installation. Older systems without python 3.7 will have trouble. See this link for details: https://openwrt.org/docs/guide-developer/quickstart-build-images
Install build packages: sudo apt install build-essential libncurses5-dev gawk git libssl-dev gettext zlib1g-dev swig unzip time rsync python3 python3-setuptools python3-yaml.
Plus specific for TIP: sudo apt-get install openvswitch-common
Doing a native build on Linux (OpenWrt 19.07 based)
First we need to clone and setup our tree. This will result in an openwrt/.
python3 setup.py --setup
Next we need to select the profile and base package selection. This setup will install the feeds, packages and generate the .config file. The available profiles are ap2220, ea8300, ecw5211, ecw5410.
cd openwrt
./scripts/gen_config.py ap2220 wlan-ap wifi
If you want to build an AX image you need to setup a different config. The available profiles are hawkeye, cypress, wallaby.
cd openwrt
./scripts/gen_config.py wallaby wifi-ax
Finally we can build the tree.
make -j X V=s
Builds for different profiles can co-exist in the same tree. Switching is done by simple calling gen_config.py again.
Doing a native build on Linux (OpenWrt 20.x based)
First we need to clone and setup our tree. This will result in an openwrt-20.x/.
python3 setup.py --setup --20x
Next we need to select the profile and base package selection. This setup will install the feeds, packages and generate the .config file. The available profiles are ap2220, ea8300, ecw5211, ecw5410. It is no longer required to add the wifi profile. Board profiles will now include their specific wifi flavour profile automatically.
cd openwrt
./scripts/gen_config.py ap2220 wlan-ap
Finally we can build the tree.
make -j X V=s
Builds for different profiles can co-exist in the same tree. Switching is done by simple calling gen_config.py again.
Doing a docker build
Start by installing docker.io on your host system and ensuring that you can run an unprivileged container. Once this is done edit the Dockerfile and choose the Ubuntu flavour. This might depend on your host installation. Then simple call (available targets are AP2220, EA8300, ECW5211, ECW5410)
TARGET=AP2200 make -j 8
