imcom / gobgp-fuzz

A fuzz tool to test robustness of GoBGP's gRPC server implementation

Purpose

This project is intended to be used as a gobgpd gRPC fuzzing test tool.

Usage

Currently only remote command is available:

Usage:
  gobgp-fuzz [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  local       A brief description of your command
  remote      Add and remove prefixes to the specified GoBGPd instance while keep dumping the global RIB

Example:

-> % go run main.go remote --help
This command lanuches goroutines to concurrently add, remove and dump prefixes.

Usage:
  gobgp-fuzz remote [flags]

Flags:
  -a, --addr string      gobgpd grpc addr (default "127.0.0.1:50051")
  -s, --cidrs strings    CIDR pool to generate prefixes (default [10.0.0.0/8])
  -c, --concurrent int   concurrent callers (default 4)
  -h, --help             help for remote

git clone [e-mail]:imcom/gobgp-fuzz.git
cd gobgp-fuzz
go mod download
go run main.go remote -a 127.0.0.1:50051 -s 10.0.0.0/8 -c 2

The command will take the CIDR and randomly remove a range from it in order to randomly generate some prefixes for the fuzz. It then starts concurrent goroutines to add, remove and dump the global rib.
