feat: Add experimental eBPF support for enhanced socket tracking (#11)

* feat: Add experimental eBPF support for enhanced socket tracking - Implement eBPF-based socket tracker for Linux with CO-RE support - Add minimal vmlinux header (5.5KB) instead of full 3.4MB file - Create graceful fallback mechanism to procfs when eBPF unavailable - Add comprehensive eBPF build documentation - Integrate libbpf-rs for eBPF program loading and management - Support both IPv4 and IPv6 socket tracking - Add capability checking for required permissions The eBPF feature is optional and disabled by default. When enabled, it provides faster and more accurate process-to-socket mapping on Linux systems with appropriate permissions.

+
+We use a **minimal vmlinux header** (`vmlinux_min.h`) instead of the full kernel headers. This approach has trade-offs that should be considered:
+
+**Benefits of minimal vmlinux_min.h:**
+
+- **Small size**: 5.5KB (203 lines) vs 3.4MB (100K+ lines) full vmlinux.h
+- **Git-friendly**: Small file size, manageable diffs, easier to review
+- **Portable**: Works across kernel versions with CO-RE/BTF
+- **Clear dependencies**: Shows exactly which kernel structures we depend on
+
+**Drawbacks of minimal vmlinux_min.h:**
+
+- **Manual maintenance**: Need to update when adding new eBPF features that access different kernel structures
+- **Potential for missing definitions**: Easy to forget required types when extending functionality
+- **Development overhead**: Requires understanding of kernel internals to extract correct definitions
+
+**Alternative approach (full vmlinux.h):**
+
+- **Pros**: Complete kernel definitions, auto-generated, no manual maintenance, never missing types
+- **Cons**: Very large file (3.4MB), but can be gitignored and generated during build process
+
+## How to Generate Full vmlinux.h (if needed)
+
+If you need to generate a complete vmlinux.h file for your kernel:
+
+```bash
+# Method 1: Using bpftool (requires root/CAP_BPF)
+sudo bpftool btf dump file /sys/kernel/btf/vmlinux format c > vmlinux.h
+
+# Method 2: Using pahole (if available)
+pahole -J /boot/vmlinux-$(uname -r)
+pahole --btf_encode_detached vmlinux.btf /boot/vmlinux-$(uname -r)
+bpftool btf dump file vmlinux.btf format c > vmlinux.h
+
+# Method 3: From kernel source
+cd /path/to/kernel/source
+make scripts_gdb
+bpftool btf dump file vmlinux format c > vmlinux.h
+```
+
+## How to Create Minimal Headers from Full vmlinux.h
+
+### 1. Identify Required Structures
+
+First, analyze your eBPF program to find which kernel structures you access:
+
+```bash
+# Find all struct references in your eBPF code
+grep -E "struct [a-zA-Z_]+" socket_tracker.bpf.c
+
+# Find BPF_CORE_READ usage to see field accesses
+grep -E "BPF_CORE_READ.*\\..*" socket_tracker.bpf.c
+
+# Common structures for socket tracking:
+# - struct sock (contains __sk_common)
+# - struct sock_common (network fields)
+# - struct msghdr (for sendmsg calls)
+# - struct sockaddr_in (IPv4 addresses)
+# - struct pt_regs (kprobe context)
+```
+
+### 2. Extract Definitions from Full vmlinux.h
+
+Use these commands to extract specific structures:
+
+```bash
+# Extract a specific struct (e.g., sock_common)
+awk '/^struct sock_common {/,/^}/' vmlinux.h
+
+# Extract type definitions
+grep "typedef.*__u[0-9]*\|typedef.*__be[0-9]*" vmlinux.h
+
+# Extract multiple related structures
+grep -A 50 "struct sock_common {" vmlinux.h
+grep -A 20 "struct sock {" vmlinux.h
+grep -A 10 "struct msghdr {" vmlinux.h
+```
+
+### 3. Create Minimal Header
+
+Create a new header file with:
+
+1. **Header guards and CO-RE pragma**:
+   ```c
+   #ifndef __VMLINUX_MIN_H__
+   #define __VMLINUX_MIN_H__
+
+   #ifndef BPF_NO_PRESERVE_ACCESS_INDEX
+   #pragma clang attribute push (__attribute__((preserve_access_index)), apply_to = record)
+   #endif
+   ```
+
+2. **Basic types** (only what you need):
+   ```c
+   typedef unsigned char __u8;
+   typedef unsigned int __u32;
+   typedef __u32 __be32;
+   // etc.
+   ```
+
+3. **Required structures** with **only the fields you access**:
+   ```c
+   struct sock_common {
+       // Only include fields accessed by BPF_CORE_READ
+       __be32 skc_daddr;
+       __be32 skc_rcv_saddr;
+       __be16 skc_dport;
+       __u16 skc_num;
+       // ... other fields you actually use
+   };
+   ```
+
+4. **Footer**:
+   ```c
+   #ifndef BPF_NO_PRESERVE_ACCESS_INDEX
+   #pragma clang attribute pop
+   #endif
+   #endif
+   ```
+
+### 4. Automated Extraction Script
+
+For complex projects, you can create a script to automate extraction:
+
+```bash
+#!/bin/bash
+# extract_minimal_vmlinux.sh
+
+FULL_VMLINUX="vmlinux.h"
+OUTPUT="vmlinux_min.h"
+BPF_SOURCE="socket_tracker.bpf.c"
+
+# Find structs used in BPF program
+STRUCTS=$(grep -oE "struct [a-zA-Z_]+" "$BPF_SOURCE" | sort -u | cut -d' ' -f2)
+
+echo "Extracting structures: $STRUCTS"
+
+# Start minimal header
+cat > "$OUTPUT" << 'EOF'
+#ifndef __VMLINUX_MIN_H__
+#define __VMLINUX_MIN_H__
+
+#ifndef BPF_NO_PRESERVE_ACCESS_INDEX
+#pragma clang attribute push (__attribute__((preserve_access_index)), apply_to = record)
+#endif
+
+/* Basic types */
+EOF
+
+# Extract basic types
+grep "typedef.*__u[0-9]*\|typedef.*__be[0-9]*\|typedef.*__kernel" "$FULL_VMLINUX" | head -20 >> "$OUTPUT"
+
+echo "" >> "$OUTPUT"
+echo "/* Network structures */" >> "$OUTPUT"
+
+# Extract each required struct
+for struct in $STRUCTS; do
+    echo "Extracting struct $struct..."
+    awk "/^struct $struct \{/,/^}/" "$FULL_VMLINUX" >> "$OUTPUT"
+    echo "" >> "$OUTPUT"
+done
+
+# Close header
+cat >> "$OUTPUT" << 'EOF'
+
+#ifndef BPF_NO_PRESERVE_ACCESS_INDEX
+#pragma clang attribute pop
+#endif
+
+#endif /* __VMLINUX_MIN_H__ */
+EOF
+
+echo "Minimal vmlinux header created: $OUTPUT"
+```
+
+## Testing Your Minimal Header
+
+After creating your minimal header:
+
+```bash
+# Test compilation
+cargo build --features ebpf
+
+# If compilation fails, check for missing definitions
+# and add them to your minimal header
+
+# Verify eBPF program loads (requires root)
+sudo cargo run --features ebpf
+```
+
+## Best Practices
+
+1. **Start minimal**: Only include structures and fields you actually access
+2. **Use CO-RE**: Always include the preserve_access_index pragma for portability
+3. **Document sources**: Note which kernel version/source your definitions came from
+4. **Test across kernels**: Verify your program works on different kernel versions
+5. **Keep synchronized**: Update minimal headers when your eBPF program changes
+
+## Troubleshooting
+
+### Compilation Errors
+
+- **Missing struct definition**: Add the struct to your minimal header
+- **Missing field**: Include the specific field in your struct definition
+- **Type errors**: Ensure all referenced types are defined
+
+### Runtime Errors
+
+- **BTF verification failed**: Check that field names match kernel structures
+- **Access violations**: Ensure you're accessing fields that exist in target kernel
+
+### Field Access Issues
+
+- **Wrong offset**: Make sure struct layout matches target kernel
+- **Missing CO-RE relocations**: Verify preserve_access_index pragma is present
+
+## Why Not Use Full vmlinux.h?
+
+While using the full vmlinux.h works, it has downsides:
+
+- **Huge file size** (3+ MB): Slows down compilation and git operations
+- **Unclear dependencies**: Hard to see what your program actually needs
+- **Kernel-specific**: Generated for one specific kernel version
+- **Review complexity**: Impossible to review 100K+ lines in PRs
+
+The minimal approach gives you the benefits of vmlinux.h (CO-RE support, exact field layouts) without the downsides.

+### eBPF Enhanced Process Identification (Experimental)
+
+When built with the `ebpf` feature on Linux, RustNet uses kernel eBPF programs for enhanced performance and lower overhead process identification. However, this comes with important limitations:
+
+**Process Name Limitations:**
+- eBPF uses the kernel's `comm` field, which is limited to 16 characters
+- Shows the task/thread command name, not the full executable path
+- Multi-threaded applications often show thread names instead of the main process name
+
+**Real-world Examples:**
+- **Firefox**: May appear as "Socket Thread", "Web Content", "Isolated Web Co", or "MainThread"
+- **Chrome**: May appear as "ThreadPoolForeg", "Chrome_IOThread", "BrokerProcess", or "SandboxHelper"
+- **Electron apps**: Often show as "electron", "node", or internal thread names
+- **System processes**: Show truncated names like "systemd-resolve" → "systemd-resolve"
+
+**Fallback Behavior:**
+- When eBPF fails to load or lacks sufficient permissions, RustNet automatically falls back to standard procfs-based process identification
+- Standard mode provides full process names but with higher CPU overhead

+eBPF is an experimental feature that requires additional capabilities for kernel program loading and performance monitoring:
+
+```bash
+# Build with eBPF support
+cargo build --release --features ebpf
+
+# Grant full capability set for eBPF (modern kernels with CAP_BPF support)
+sudo setcap 'cap_net_raw,cap_net_admin,cap_bpf,cap_perfmon+eip' ./target/release/rustnet

+
+# Run without sudo - eBPF programs will load automatically if capabilities are sufficient
+./target/release/rustnet
+```
+
+**Capability requirements for eBPF:**
+- `CAP_NET_RAW` - Raw socket access for packet capture
+- `CAP_NET_ADMIN` - Network administration 
+- `CAP_BPF` - BPF program loading (Linux 5.8+, preferred)
+- `CAP_PERFMON` - Performance monitoring (Linux 5.8+, preferred)  
+- `CAP_SYS_ADMIN` - System administration (fallback for older kernels)
+
+The application will automatically detect available capabilities and fall back to procfs-only mode if eBPF cannot be loaded.

 ## Platform Support

- **Windows Support**: ✅ Basic functionality working with Npcap SDK and runtime. Process identification not yet implemented for Windows
+- **Windows Support**: Basic functionality working with Npcap SDK and runtime. Process identification not yet implemented for Windows
 - **BSD Support**: Add support for FreeBSD, OpenBSD, and NetBSD
- **Linux Process Identification Enhancement**: Investigate using **eBPF** (Extended Berkeley Packet Filter) for direct kernel-level process identification similar to macOS PKTAP. This would provide more accurate and efficient process-to-connection mapping than the current `/proc` filesystem approach, especially for high-throughput scenarios.
+- **Linux Process Identification**: **Experimental eBPF Support Implemented** - Basic eBPF-based process identification now available with `--features ebpf`. Provides efficient kernel-level process-to-connection mapping with lower overhead than procfs. Currently has limitations (see eBPF Improvements section below).
+
+## eBPF Improvements (Linux)
+
+The experimental eBPF support provides efficient process identification but has several areas for improvement:
+
+### Current Limitations
+- **Process Names Limited to 16 Characters**: Uses kernel `comm` field, causing truncation (e.g., "Firefox" → "Socket Thread")
+- **Thread Names vs Process Names**: Shows thread command names instead of full executable names
+- **Minimal vmlinux.h Maintenance**: Current approach requires manual updates when adding new kernel structure access
+
+### Planned Improvements
+- **Hybrid eBPF + Procfs Approach**: Use eBPF for connection tracking, selectively lookup full process names via procfs for better accuracy
+- **Full Executable Path Resolution**: Investigate accessing full process executable path from eBPF programs
+- **Better Process-Thread Mapping**: Improve mapping from thread IDs to parent process information
+- **vmlinux.h Strategy**: Consider switching to full auto-generated vmlinux.h for easier maintenance vs current minimal approach
+- **Enhanced BTF Support**: Better compatibility across different kernel versions and distributions
+- **Performance Optimizations**: Reduce eBPF map lookups and improve connection-to-process matching efficiency
+
+### Future Enhancements
+- **Real-time Process Updates**: Track process name changes and executable updates
+- **Container Support**: Better process identification within containerized environments
+- **Security Context**: Include process security attributes (capabilities, SELinux context, etc.)
