This is still not enough. Since the build kind of assumes Ubuntu as the only distro and enables XDP everywhere except Ubuntu 20.04: https://github.com/microsoft/msquic/blob/5052f346237bd53907b227aa7a10cd638be9dcf3/src/platform/CMakeLists.txt#L38

Which leads to:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
BPF_LIB
    linked by target "platform" in directory /tmp/msquic/src/platform
NL_LIB
    linked by target "platform" in directory /tmp/msquic/src/platform
NL_ROUTE_LIB
    linked by target "platform" in directory /tmp/msquic/src/platform
XDP_LIB
    linked by target "platform" in directory /tmp/msquic/src/platform

on Alpine.

Thanks for the change. As far as I remember, our docker environment doesn't have /etc/os-release. let me double check

[ami-GS]

Exists!😵‍💫

[ManickaP]

I renamed the parameter, updated the pipeline (hopefully in the right place) and removed QUIC_CARGO_BUILD, PTAL.

Everything looks good to me, but @ami-GS can you please take a look? I noticed netperf failed, but I wonder if this is because of something else being broken? I know you're working on that in a parallel PR.

[nibanks]

What should we do for the Official, OneBranch builds? Enabled or disabled?

[ami-GS]

rerunning BVT xdp test...

[ami-GS]

Could you update Linux XDP documentation? I believe build.ps1 requires additional parameter

BTW, I don't have rights to merge this, so unless there is more feedback to address (let me know if there still something is), feel free to merge on my behalf. And thanks all for help with this!
