Fedora update notification for grout addresses denial of service issues, ensuring a stable network application for users.
New version of frr and grout

Summary

grout stands for Graph Router. In English, "grout" refers to thin mortar that

hardens to fill gaps between tiles.

grout is a DPDK based network processing application. It uses the rte_graph

library for data path processing.

Its main purpose is to simulate a network function or a physical router for

testing/replicating real (usually closed source) VNF/CNF behavior with an

open-source tool.

It comes with a client library to configure it over a standard UNIX socket and

a CLI that uses that library. The CLI can be used as an interactive shell, but

also in scripts one command at a time, or by batches.

Update Information:

New version of frr and grout. I am keeping libyang to version 3 at the moment due to recommendations from https://github.com/FRRouting/frr/blob/master/doc/developer/building-libyang.rst. Once changes to build with libyang5 land, I will rebase libyang as well.
