full diff: https://github.com/opencontainers/runc/compare/v1.0.0-rc92...v1.0.0-rc93 release notes: https://github.com/opencontainers/runc/releases/tag/v1.0.0-rc93 Release notes for runc v1.0.0-rc93 ------------------------------------------------- This is the last feature-rich RC release and we are in a feature-freeze until 1.0. 1.0.0~rc94 will be released in a few weeks with minimal bug fixes only, and 1.0.0 will be released soon afterwards. - runc's cgroupv2 support is no longer considered experimental. It is now believed to be fully ready for production deployments. In addition, runc's cgroup code has been improved: - The systemd cgroup driver has been improved to be more resilient and handle more systemd properties correctly. - We now make use of openat2(2) when possible to improve the security of cgroup operations (in future runc will be wholesale ported to libpathrs to get this protection in all codepaths). - runc's mountinfo parsing code has been reworked significantly, making container startup times significantly faster and less wasteful in general. - runc now has special handling for seccomp profiles to avoid making new syscalls unusable for glibc. This is done by installing a custom prefix to all seccomp filters which returns -ENOSYS for syscalls that are newer than any syscall in the profile (meaning they have a larger syscall number). This should not cause any regressions (because previously users would simply get -EPERM rather than -ENOSYS, and the rule applied above is the most conservative rule possible) but please report any regressions you find as a result of this change -- in particular, programs which have special fallback code that is only run in the case of -EPERM. - runc now supports the following new runtime-spec features: - The umask of a container can now be specified. - The new Linux 5.9 capabilities (CAP_PERFMON, CAP_BPF, and CAP_CHECKPOINT_RESTORE) are now supported. - The "unified" cgroup configuration option, which allows users to explicitly specify the limits based on the cgroup file names rather than abstracting them through OCI configuration. This is currently limited in scope to cgroupv2. - Various rootless containers improvements: - runc will no longer cause conflicts if a user specifies a custom device which conflicts with a user-configured device -- the user device takes precedence. - runc no longer panics if /sys/fs/cgroup is missing in rootless mode. - runc --root is now always treated as local to the current working directory. - The --no-pivot-root hardening was improved to handle nested mounts properly (please note that we still strongly recommend that users do not use --no-pivot-root -- it is still an insecure option). - A large number of code cleanliness and other various cleanups, including fairly large changes to our tests and CI to make them all run more efficiently. For packagers the following changes have been made which will have impact on your packaging of runc: - The "selinux" and "apparmor" buildtags have been removed, and now all runc builds will have SELinux and AppArmor support enabled. Note that "seccomp" is still optional (though we very highly recommend you enable it). - make install DESTDIR= now functions correctly. Signed-off-by: Sebastiaan van Stijn <github@gone.nl> |

About
This directory contains a collection of scripts used to build and manage this repository. If there are any issues regarding the intention of a particular script (or even part of a certain script), please reach out to us. It may help us either refine our current scripts, or add on new ones that are appropriate for a given use case.
DinD (dind.sh)
DinD is a wrapper script which allows Docker to be run inside a Docker container. DinD requires the container to be run with privileged mode enabled.
Generate Authors (generate-authors.sh)
Generates AUTHORS; a file with all the names and corresponding emails of individual contributors. AUTHORS can be found in the home directory of this repository.
Make
There are two make files, each with different extensions. Neither are supposed
to be called directly; only invoke make. Both scripts run inside a Docker
container.
make.ps1
- The Windows native build script that uses PowerShell semantics; it is limited
unlike
hack\make.shsince it does not provide support for the full set of operations provided by the Linux counterpart,make.sh. However,make.ps1does provide support for local Windows development and Windows to Windows CI. More information is found withinmake.ps1by the author, @jhowardmsft
make.sh
- Referenced via
make testwhen running tests on a local machine, or directly referenced when running tests inside a Docker development container. - When running on a local machine,
make testto run all tests found intest,test-unit,test-integration, andtest-docker-pyon your local machine. The default timeout is set inmake.shto 60 minutes (${TIMEOUT:=60m}), since it currently takes up to an hour to run all of the tests. - When running inside a Docker development container,
hack/make.shdoes not have a single target that runs all the tests. You need to provide a single command line with multiple targets that performs the same thing. An example referenced from Run targets inside a development container:root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration test-docker-py - For more information related to testing outside the scope of this README, refer to Run tests and test documentation
Vendor (vendor.sh)
A shell script that is a wrapper around Vndr. For information on how to use this, please refer to vndr's README
