Fedora 35: 2021-0cda131052 Moderate: Keepalived D-Bus Access Control Fix

Keepalived provides simple and robust facilities for load balancing

and high availability to Linux system and Linux based infrastructures.

The load balancing framework relies on well-known and widely used

Linux Virtual Server (IPVS) kernel module providing Layer4 load

balancing. Keepalived implements a set of checkers to dynamically and

adaptively maintain and manage load-balanced server pool according

their health. High availability is achieved by VRRP protocol. VRRP is

a fundamental brick for router failover. In addition, keepalived

implements a set of hooks to the VRRP finite state machine providing

low-level and high-speed protocol interactions. Keepalived frameworks

can be used independently or all together to provide resilient

infrastructures.
