cuttlefish signaling server responds with malformed headers on GET /devices Bug: 213124544 Test: launch webrtc_operator, make a request with browser and observer response data. 1. HOME=$PWD bin/webrtc_operator -assets_dir=$PWD/usr/share/webrtc/assets -certs_dir=$PWD/usr/share/webrtc/certs -http_server_port=8080 -use_secure_http=false 2. start `sudo tcpdump -i ens4 port 8080 -vv`, use fiddler or owasp ZAP to observe raw request/response data 3. Use a browser to access signaling server (http://127.0.0.1:8080) 4. Check headers of GET /devices response, paying attention to mandatory colon separating header name and value Change-Id: Ied8c0183bf863d07dbe7909a37dc0d3ccde927fa
Make sure virtualization with KVM is available.
grep -c -w "vmx\|svm" /proc/cpuinfo
This should return a non-zero value. If running on a cloud machine, this may take cloud-vendor-specific steps to enable. For Google Compute Engine specifically, see the GCE guide.
ARM specific steps:
/dev/kvm. Note that this method can also be used to confirm support of KVM on any environment.Download, build, and install the host debian package:
sudo apt install -y git devscripts config-package-dev debhelper-compat git clone https://github.com/google/android-cuttlefish cd android-cuttlefish debuild -i -us -uc -b sudo dpkg -i ../cuttlefish-common_*_*64.deb || sudo apt-get install -f sudo usermod -aG kvm,cvdnetwork $USER sudo reboot
The reboot will trigger installing additional kernel modules and applying udev rules.
Go to http://ci.android.com/
Enter a branch name. Start with aosp-master if you don‘t know what you’re looking for
Navigate to aosp_cf_x86_64_phone and click on userdebug for the latest build
Click on Artifacts
Scroll down to the OTA images. These packages look like aosp_cf_x86_64_phone-img-xxxxxx.zip -- it will always have img in the name. Download this file
Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.
On your local system, combine the packages:
mkdir cf cd cf tar xvf /path/to/cvd-host_package.tar.gz unzip /path/to/aosp_cf_x86_64_phone-img-xxxxxx.zip
Launch cuttlefish with:
$ HOME=$PWD ./bin/launch_cvd
$ HOME=$PWD ./bin/stop_cvd
You can use adb to debug it, just like a physical device:
$ ./bin/adb -e shell
When launching with ---start_webrtc (the default), you can see a list of all available devices at https://localhost:8443 . For more information, see the WebRTC on Cuttlefish documentation.
