runc v1.2.0 -- "できるときにできることをやるんだ。それが今だ。"

This is the long-awaited release of runc 1.2.0! The primary changes from rc3 are general improvements and fixes for minor regressions related to the new /proc/self/exe cloning logic in runc 1.2, follow-on patches related to CVE-2024-45310, as well as some other minor changes.

• In order to alleviate the remaining concerns around the memory usage and (arguably somewhat unimportant, but measurable) performance overhead of memfds for cloning /proc/self/exe, we have added a new protection using overlayfs that is used if you have enough privileges and the running kernel supports it. It has effectively no performance nor memory overhead (compared to no cloning at all). (#4448)
• The original fix for CVE-2024-45310 was intentionally very limited in scope to make it easier to review, however it also did not handle all possible os.MkdirAll cases and thus could lead to regressions. We have switched to the more complete implementation in the newer versions of github.com/cyphar/filepath-securejoin. (#4393, #4400, #4421, #4430)
• In certain situations (a system with lots of mounts or racing mounts) we could accidentally end up leaking mounts from the container into the host. This has been fixed. (#4417)
• The fallback logic for O_TMPFILE clones of /proc/self/exe had a minor bug that would cause us to miss non-noexec directories and thus fail to start containers on some systems. (#4444)
• Sometimes the cloned /proc/self/exe file descriptor could be placed in a way that it would get clobbered by the Go runtime. We had a fix for this already but it turns out it could still break in rare circumstances, but it has now been fixed. (#4294, #4452)
• It is not possible for runc kill to work properly in some specific configurations (such as rootless containers with no cgroups and a shared pid namespace). We now output a warning for such configurations. (#4398)
• memfd-bind: update the documentation and make path handling with the systemd unit more idiomatic. (#4428)
• We now use v0.16 of Cilium's eBPF library, including fixes that quite a few downstreams asked for. (#4397, #4396)
• Some internal runc init synchronisation that was no longer necessary (due to the /proc/self/exe cloning move to Go) was removed. (#4441)

Changelog

Sourced from github.com/opencontainers/runc's changelog.

[1.2.1] - 2024-11-01

No existe una escuela que enseñe a vivir.

Fixed

• Became root after joining an existing user namespace. Otherwise, runc won't have permissions to configure some mounts when running under SELinux and runc is not creating the user namespace. (#4466, #4477)

Removed

• Remove dependency on golang.org/x/sys/execabs from go.mod. (#4480)
• Remove runc-dmz, that had many limitations, and is mostly made obsolete by the new protection mechanism added in v1.2.0. Note that runc-dmz was only available only in the 1.2.0 release and required to set an environment variable to opt-in. (#4488)

Added

• The script/check-config.sh script now checks for overlayfs support. (#4494)
• When using cgroups v2, allow to set or update memory limit to "unlimited" and swap limit to a specific value. (#4501)
