I missed the snark of @quinnypig.com because I wanted to yell about containerd and cgroups at Apple. The sacrifices we make at #kubecon.

Główny problem pojawił się na styku Containerd z AppArmor (system bezpieczeństwa, coś jak SELinux, ale prostszy).

Oficjalna porada od developerów? "Wyłącz systemy Apparmor i po problemie!". Wyłączenie systemów bezpieczeństwa w celu umożliwienia działania patcha bezpieczeństwa... 🤔

Tysiące zaktualizowanych Dockerów.

Szybko (w kilka godzin) ogarnęliśmy hotfixa polegającego na obniżeniu containerd do poprzedniej, działającej wersji. Działało super na Ubuntu 24.04, ale kiepsko na starych Debianach i Ubuntu 22.04, bo tam upgrade pakietów był szerszy.

5 listopada wyszła jednak nowa wersja Dockera (28.5.2), a wraz z nią aktualizacje dla ContainerD (zarządza cyklem życia kontenerów) oraz Runc (uruchamia realny kontener).

Po co ta aktualizacja? Aby załatać 3 krytyczne podatności, które umożliwiały ucieczkę z kontenera.

CPU quota calculation mismatch between containerd and runc causes container creation failure · Issue #4982 · opencontainers/runc · GitHub
✨ Check out this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: Description When using the systemd cgroup driver with a CPU limit of 4096m, pod creation fails intermittently because containerd non-deterministically calculates either 409600 or 410000 microseconds for the parent cgroup, while runc consistently calculates 410000 for child cgroups. When they mismatch, the Linux kernel rejects the child cgroup creation with "invalid argument".

this is the first issue I've had with it and it wasn't even its fault. It's something to do with the latest containerd version and running an LXC container on Proxmox. A net.ipv4 permission broke with this combination.
