kata-containers Changes

In this release we're posting the shortlog between 3.2.0-alpha0 and 3.2.0-alpha3,
as the -alpha1 and -alpha2 releases couldn't be finished due to issues in our
release pipeline.

The most notorious changes that are worth mentioning are:

  • The addition of device manager for runtime-rs
  • Several improvements related to GPU usage with Kata Containers
  • Several improvements to the kata-ctl tool
  • Addition of artefacts and specific runtime classes for x86_64 TEEs
    • SEV, SNP, and TDX are the ones being tested, built, and shipped for now
  • Multi-architecture release, including:
  • Several other bug fixes happened all over the code

Libseccomp Notices

The kata-agent binaries inside the Kata Containers images provided with this release are
statically linked with the following GNU LGPL-2.1 licensed libseccomp library.

The kata-agent uses the libseccomp v2.5.4 which is not modified from the upstream version.
However, in order to comply with the LGPL-2.1 (§6(a)), we attach the complete source code for the library.

If you want to use the kata-agent which is not statically linked with the library, you can build
a custom kata-agent that does not use the library from sources.
For the details, please check the developer guide.
