Fedora 34: FEDORA-2021-eb2742b148 Critical: Containerd and Moby-Engine Fix

The latest patch for Fedora 34 resolves a critical vulnerability in containerd and moby-engine attributed to CVE-2021-41190.
Update containerd and moby-engine - Security fix for CVE-2021-41190

Summary

GRPC for low-memory environments.

The existing grpc-go project requires a lot of memory overhead for importing

packages and at runtime. While this is great for many services with low density

requirements, this can be a problem when running a large number of services on a

single machine or on a machine with a small amount of memory.

Using the same GRPC definitions, this project reduces the binary size and

protocol overhead required. We do this by eliding the net/http, net/http2 and

grpc package used by grpc replacing it with a lightweight framing protocol. The

result are smaller binaries that use less resident memory with the same ease of

use as GRPC.
