Build tcpdirect packages from tree

[HFTrader]

I am running Ubuntu 20.04 LTS. It seems that kernels 5.15+ do not compile anymore with the standard packaged files from the official site https://www.xilinx.com/support/download/nic-software-and-drivers.html#tcpdirect.

The only way I got onload to install is from taking code from the Github master and compiling. However, while I am able to build and install onload with onload/scripts/onload_install, I am not able to install tcpdirect from sources with tcpdirect/scripts/zf_install.

How to build and package tcpdirect?

Hi @HFTrader,

The zf_install script is run from within a distributed package (e.g. binary tarball) not from the source tree, unlike onload_install which works in both contexts. So you would first create a package of some form.

The packaging scripts will be reworked in due course to support the first feature release from open source but this has not been done yet so I'm afraid this is a slightly fiddly process at the moment, sorry!

You can expect a production update release of Onload shortly that works with the CVE mitigation in recent kernels distributed by OS vendors: Xilinx-CNS/onload#216.

@HFTrader, the v8.1.3 releases of OpenOnload and TCPDirect are now out and available via the usual channel. These should deal with your build issue!
