LXCFS 5.0 LTS has been released¶
2022年3月10日
Introduction¶
The LXCFS team is pleased to announce the release of LXCFS 5.0.0!
This is the result of two years of work since the LXCFS 4.0.0 release and is the fourth LTS release for the LXCFS project. This release will be supported until June 2027.
Major changes¶
Switch to meson¶
With this release of LXCFS, autotools is being replaced by meson as the build tooling. Compatibility Makefile targets are provided for all, install and dist.
This is a change which is particularly relevant for packagers as it otherwise has no user visible impact.
CGroup2 support¶
LXCFS 5.0 properly detects and handles cgroup2, using the cgroup2 hierarchy to fetch the resource consumption information for the container. It also automatically disables the cgroup directory feature when run on a cgroup2 system.
/proc/slabinfo support¶
The per-cgroup slab allocation is now used to provide a container view of /proc/slabinfo.
/sys/devices/system/cpu/ support¶
In addition to the existing /sys/devices/system/cpu/online support, LXCFS will now virtualize the entire /sys/devices/system/cpu directory in order to hide CPUs which aren't available to the container.
Support and upgrade¶
LXCFS 5.0.0 will be supported until June 2027 and our current LTS release, LXCFS 4.0 will now switch to a slower maintenance pace, only getting critical bugfixes and security updates.
We strongly recommend all LXCFS users to plan an upgrade to the 5.0 branch.
