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>
