Pros of BCC

• More mature and widely adopted in the eBPF community
• Extensive collection of pre-built tools for various use cases
• Supports multiple programming languages (Python, Lua, C++)

Cons of BCC

• Heavier dependency footprint, requiring LLVM and kernel headers
• Steeper learning curve for beginners
• Less suitable for production environments due to compilation overhead

Code Comparison

BCC example (Python):

from bcc import BPF

program = """
int hello(void *ctx) {
    bpf_trace_printk("Hello, World!\\n");
    return 0;
}
"""

b = BPF(text=program)
b.attach_kprobe(event="sys_clone", fn_name="hello")
b.trace_print()

Cilium eBPF example (Go):

import "github.com/cilium/ebpf"

prog, err := ebpf.NewProgram(&ebpf.ProgramSpec{
    Name:    "hello",
    Type:    ebpf.Kprobe,
    Instructions: ebpf.Instructions{
        ebpf.FnTracePrintk.Call().Const("Hello, World!\n"),
        ebpf.Return(),
    },
})

Both libraries provide eBPF functionality, but Cilium eBPF offers a more lightweight and production-ready approach, while BCC excels in rapid prototyping and provides a rich set of pre-built tools for various use cases.

Pros of libbpf

• Written in C, providing low-level access and potentially better performance
• Closer to the kernel, offering more direct control over eBPF functionality
• Widely used and supported by the Linux kernel community

Cons of libbpf

• Steeper learning curve, especially for developers not familiar with C
• Less abstraction, requiring more manual management of eBPF programs
• Limited cross-platform support compared to higher-level libraries

Code Comparison

libbpf example:

#include <bpf/bpf.h>
#include <bpf/libbpf.h>

int main() {
    struct bpf_object *obj = bpf_object__open("program.o");
    bpf_object__load(obj);
    // Additional setup and usage
}

ebpf example:

import "github.com/cilium/ebpf"

func main() {
    spec, _ := ebpf.LoadCollectionSpec("program.o")
    coll, _ := ebpf.NewCollection(spec)
    // Additional setup and usage
}

The ebpf library provides a higher-level abstraction, making it easier to work with eBPF programs in Go. It offers a more user-friendly API and handles many low-level details automatically. However, libbpf provides more fine-grained control and is closer to the kernel, which can be advantageous for certain use cases or when maximum performance is required.

Pros of Tracee

• Focused on runtime security and threat detection
• Provides a higher-level abstraction for eBPF-based tracing
• Includes pre-built detection rules and event types

Cons of Tracee

• More specialized for security use cases
• Less flexible for general-purpose eBPF programming
• Steeper learning curve for customization

Code Comparison

Tracee (event definition):

events.RegisterEventType("file_write", &events.RegisterEventTypeParams{
    Name:     "file_write",
    Desc:     "File write operation",
    Origin:   "tracee",
    IsSyscall: true,
})

eBPF (program loading):

spec, err := ebpf.LoadCollectionSpec("path/to/bpf.o")
if err != nil {
    log.Fatalf("failed to load BPF spec: %v", err)
}

Summary

Tracee is a specialized tool for runtime security and threat detection using eBPF, while eBPF is a more general-purpose library for working with eBPF programs. Tracee offers higher-level abstractions and pre-built security features, making it easier to implement security monitoring. However, eBPF provides more flexibility for various eBPF use cases beyond security. The choice between the two depends on the specific requirements of your project and your familiarity with eBPF programming.

Pros of Falco

• Comprehensive security monitoring and threat detection for cloud-native environments
• Out-of-the-box rules and configurations for common security scenarios
• Integration with popular alerting and notification systems

Cons of Falco

• Steeper learning curve for customizing rules and configurations
• Higher resource consumption compared to lightweight eBPF libraries
• More focused on security monitoring, less versatile for general-purpose eBPF programming

Code Comparison

Falco rule example:

- rule: Detect Suspicious File Access
  desc: Detect access to sensitive files
  condition: open_read and sensitive_files
  output: "Sensitive file opened for reading (user=%user.name file=%fd.name)"
  priority: WARNING

eBPF program using cilium/ebpf:

const source string = `
#include <linux/bpf.h>
#include <bpf/bpf_helpers.h>

SEC("kprobe/sys_open")
int kprobe_open(void *ctx) {
    bpf_trace_printk("sys_open called\\n");
    return 0;
}
`

Summary

Falco provides a more comprehensive security monitoring solution with pre-built rules, while cilium/ebpf offers a lower-level library for general-purpose eBPF programming. Falco is better suited for security-focused use cases, while cilium/ebpf provides more flexibility for custom eBPF applications across various domains.

Pros of bpftrace

• High-level language for writing eBPF programs, making it easier for users to create tracing scripts
• Extensive built-in functions and probes for common tracing scenarios
• Supports one-liners for quick debugging and analysis

Cons of bpftrace

• Limited to tracing and observability use cases
• May have higher overhead for complex programs compared to lower-level eBPF implementations

Code Comparison

bpftrace example:

#!/usr/bin/env bpftrace
BEGIN {
    printf("Tracing TCP connects. Hit Ctrl-C to end.\n");
}
kprobe:tcp_connect {
    printf("TCP connect: %s\n", comm);
}

ebpf example (using Go):

prog := &ebpf.Program{
    Type:    ebpf.Kprobe,
    Name:    "tcp_connect",
    License: "GPL",
    Instructions: asm.Instructions{
        // eBPF instructions here
    },
}

Summary

bpftrace provides a high-level, user-friendly approach to eBPF tracing, while ebpf offers a more flexible, low-level API for broader eBPF applications. bpftrace is ideal for quick tracing tasks, while ebpf is better suited for complex, performance-critical eBPF programs across various use cases.
