We explicitely set the Postion Independant Executlable (PIE) options in the extra CFLAGS and LDFLAGS that are passed to the QEMU configure script for all archs. This means that these options are used pretty much everywhere, including when building the sample plugins under the test directory. These cannot be linked with -pie and break the build, as experienced recently on ARM (see PR #2732). This only broke on ARM because other archs are configured with --disable-tcg : this disables plugins which are built by default otherwise. The --enable-pie option is all that is needed. The QEMU build system knows which binaries should be created as PIE, e.g. the important bits like QEMU and virtiofsd, and which ones should not, e.g. the sample plugins that aren't used in production. Rely on --enable-pie only, for all archs. This allows to drop the workaround that was put in place in PR #2732. Fixes: #2757 Signed-off-by: Greg Kurz <groug@kaod.org> |

Kata Containers
Welcome to Kata Containers!
This repository is the home of the Kata Containers code for the 2.0 and newer releases.
If you want to learn about Kata Containers, visit the main Kata Containers website.
Introduction
Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs.
Getting started
See the installation documentation.
Documentation
See the official documentation (including installation guides, the developer guide, design documents and more).
Community

Components
Main components
The table below lists the core parts of the project:
| Component | Type | Description |
|---|---|---|
| runtime | core | Main component run by a container manager and providing a containerd shimv2 runtime implementation. |
| agent | core | Management process running inside the virtual machine / POD that sets up the container environment. |
| documentation | documentation | Documentation common to all components (such as design and install documentation). |
| tests | tests | Excludes unit tests which live with the main code. |
Additional components
The table below lists the remaining parts of the project:
| Component | Type | Description |
|---|---|---|
| packaging | infrastructure | Scripts and metadata for producing packaged binaries (components, hypervisors, kernel and rootfs). |
| kernel | kernel | Linux kernel used by the hypervisor to boot the guest image. Patches are stored here. |
| osbuilder | infrastructure | Tool to create "mini O/S" rootfs and initrd images and kernel for the hypervisor. |
agent-ctl |
utility | Tool that provides low-level access for testing the agent. |
trace-forwarder |
utility | Agent tracing helper. |
ci |
CI | Continuous Integration configuration files and scripts. |

Packaging and releases
Kata Containers is now available natively for most distributions. However, packaging scripts and metadata are still used to generate snap and GitHub releases. See the components section for further details.
