# 🎯 eBPF Integration Complete with Security Validation
|
|
|
|
## ✅ Implementation Summary
|
|
|
|
Your Linux diagnostic agent now has **comprehensive eBPF monitoring capabilities** with **robust security validation**:
|
|
|
|
### 🔒 **Security Checks Implemented**
|
|
|
|
1. **Root Privilege Validation**
|
|
- ✅ `checkRootPrivileges()` - Ensures `os.Geteuid() == 0`
|
|
- ✅ Clear error message with explanation
|
|
- ✅ Program exits immediately if not root
|
|
|
|
2. **Kernel Version Validation**
|
|
- ✅ `checkKernelVersion()` - Requires Linux 4.4+ for eBPF support
|
|
- ✅ Parses kernel version (`uname -r`)
|
|
- ✅ Validates major.minor >= 4.4
|
|
- ✅ Program exits with detailed error for old kernels
|
|
|
|
3. **eBPF Subsystem Validation**
|
|
- ✅ `checkEBPFSupport()` - Validates BPF syscall availability
|
|
- ✅ Tests debugfs mount status
|
|
- ✅ Verifies eBPF kernel support
|
|
- ✅ Graceful warnings for missing components
|
|
|
|
### 🚀 **eBPF Capabilities**
|
|
|
|
- **Cilium eBPF Library Integration** (`github.com/cilium/ebpf`)
|
|
- **Dynamic Program Compilation** via bpftrace
|
|
- **AI-Driven Program Selection** based on issue analysis
|
|
- **Real-Time Kernel Monitoring** (tracepoints, kprobes, kretprobes)
|
|
- **Automatic Program Cleanup** with time limits
|
|
- **Professional Diagnostic Integration** with TensorZero
|
|
|
|
### 🧪 **Testing Results**
|
|
|
|
```bash
|
|
# Non-root execution properly blocked ✅
|
|
$ ./nannyagent-ebpf
|
|
❌ ERROR: This program must be run as root for eBPF functionality.
|
|
Please run with: sudo ./nannyagent-ebpf
|
|
|
|
# Kernel version validation working ✅
|
|
Current kernel: 6.14.0-29-generic
|
|
✅ Kernel meets minimum requirement (4.4+)
|
|
|
|
# eBPF subsystem detected ✅
|
|
✅ bpftrace binary available
|
|
✅ perf binary available
|
|
✅ eBPF syscall is available
|
|
```
|
|
|
|
## 🎯 **Updated System Prompt for TensorZero**
|
|
|
|
The agent now works with the enhanced system prompt that includes:
|
|
|
|
- **eBPF Program Request Format** with `ebpf_programs` array
|
|
- **Category-Specific Recommendations** (Network, Process, File I/O, Performance)
|
|
- **Enhanced Resolution Format** with `ebpf_evidence` field
|
|
- **Comprehensive eBPF Guidelines** for AI model
|
|
|
|
## 🔧 **Production Deployment**
|
|
|
|
### **Requirements:**
|
|
- ✅ Linux kernel 4.4+ (validated at startup)
|
|
- ✅ Root privileges (validated at startup)
|
|
- ✅ bpftrace installed (auto-detected)
|
|
- ✅ TensorZero endpoint configured
|
|
|
|
### **Deployment Commands:**
|
|
```bash
|
|
# Basic deployment with root privileges
|
|
sudo ./nannyagent-ebpf
|
|
|
|
# With TensorZero configuration
|
|
sudo NANNYAPI_ENDPOINT='http://tensorzero.internal:3000/openai/v1' ./nannyagent-ebpf
|
|
|
|
# Example diagnostic session
|
|
echo "Network connection timeouts to database" | sudo ./nannyagent-ebpf
|
|
```
|
|
|
|
### **Safety Features:**
|
|
- 🔒 **Privilege Enforcement** - Won't run without root
|
|
- 🔒 **Version Validation** - Ensures eBPF compatibility
|
|
- 🔒 **Time-Limited Programs** - Automatic cleanup (10-30 seconds)
|
|
- 🔒 **Read-Only Monitoring** - No system modifications
|
|
- 🔒 **Error Handling** - Graceful fallback to traditional diagnostics
|
|
|
|
## 📊 **Example eBPF-Enhanced Diagnostic Flow**
|
|
|
|
### **User Input:**
|
|
> "Application randomly fails to connect to database"
|
|
|
|
### **AI Response with eBPF:**
|
|
```json
|
|
{
|
|
"response_type": "diagnostic",
|
|
"reasoning": "Database connection issues require monitoring TCP connections and DNS resolution",
|
|
"commands": [
|
|
{"id": "db_check", "command": "ss -tlnp | grep :5432", "description": "Check database connections"}
|
|
],
|
|
"ebpf_programs": [
|
|
{
|
|
"name": "tcp_connect_monitor",
|
|
"type": "kprobe",
|
|
"target": "tcp_connect",
|
|
"duration": 20,
|
|
"filters": {"comm": "myapp"},
|
|
"description": "Monitor TCP connection attempts from application"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
### **Agent Execution:**
|
|
1. ✅ Validates root privileges and kernel version
|
|
2. ✅ Runs traditional diagnostic commands
|
|
3. ✅ Starts eBPF program to monitor TCP connections
|
|
4. ✅ Collects real-time kernel events for 20 seconds
|
|
5. ✅ Returns combined traditional + eBPF results to AI
|
|
|
|
### **AI Resolution with eBPF Evidence:**
|
|
```json
|
|
{
|
|
"response_type": "resolution",
|
|
"root_cause": "DNS resolution timeouts causing connection failures",
|
|
"resolution_plan": "1. Configure DNS servers\n2. Test connectivity\n3. Restart application",
|
|
"confidence": "High",
|
|
"ebpf_evidence": "eBPF tcp_connect traces show 15 successful connections to IP but 8 failures during DNS lookup attempts"
|
|
}
|
|
```
|
|
|
|
