d449513861 Add MUSL static binary build system using Alpine Docker
- Create Dockerfile.alpine-musl for truly portable static binaries
- Update build_static.sh to use Docker with sudo fallback
- Fix source code portability issues for MUSL:
  * Add missing headers in config.c, dm_admin.c
  * Remove glibc-specific headers in nip009.c, subscriptions.c
- Update nostr_core_lib submodule with fortification fix
- Add comprehensive documentation in docs/musl_static_build.md

Binary characteristics:
- Size: 7.6MB (vs 12MB+ for glibc static)
- Dependencies: Zero (truly portable)
- Compatibility: Any Linux distribution
- Build time: ~2 minutes with Docker caching

Resolves fortification symbol issues (__snprintf_chk, __fprintf_chk)
that prevented MUSL static linking.

- [x] NIP-50: Keywords filter
- [x] NIP-70: Protected Events
## Quick Start
Get your C-Relay up and running in minutes with a static binary (no dependencies required):
### 1. Download Static Binary
Download the latest static release from the [releases page](https://git.laantungir.net/laantungir/c-relay/releases):
```bash
# Static binary - works on all Linux distributions (no dependencies)
wget https://git.laantungir.net/laantungir/c-relay/releases/download/v0.6.0/c-relay-v0.6.0-linux-x86_64-static
chmod +x c-relay-v0.6.0-linux-x86_64-static
mv c-relay-v0.6.0-linux-x86_64-static c-relay
```
### 2. Start the Relay
Simply run the binary - no configuration files needed:
```bash
./c-relay
```
On first startup, you'll see:
- **Admin Private Key**: Save this securely! You'll need it for administration
- **Relay Public Key**: Your relay's identity on the Nostr network
- **Port Information**: Default is 8888, or the next available port
### 3. Access the Web Interface
Open your browser and navigate to:
```
http://localhost:8888/api/
```
The web interface provides:
- Real-time configuration management
- Database statistics dashboard
- Auth rules management
- Secure admin authentication with your Nostr identity
### 4. Test Your Relay
Test basic connectivity:
```bash
# Test WebSocket connection
curl -H "Accept: application/nostr+json" http://localhost:8888
# Test with a Nostr client
# Add ws://localhost:8888 to your client's relay list
```
### 5. Configure Your Relay (Optional)
Use the web interface or send admin commands to customize:
- Relay name and description
- Authentication rules (whitelist/blacklist)
- Connection limits
- Proof-of-work requirements
**That's it!** Your relay is now running with zero configuration required. The event-based configuration system means you can adjust all settings through the web interface or admin API without editing config files.
## Web Admin Interface

In addition to the above admin API, c-relay allows the administrator to direct message the relay to get information or control some settings. As long as the administrator is signed in with any nostr client that allows sending nip-17 direct messages (DMs), they can control the relay.

# MUSL Static Binary Build Guide
## Overview
This guide explains how to build truly portable MUSL-based static binaries of c-relay using Alpine Linux Docker containers. These binaries have **zero runtime dependencies** and work on any Linux distribution.
## Why MUSL?
### MUSL vs glibc Static Binaries
**MUSL Advantages:**
- **Truly Static**: No hidden dependencies on system libraries
- **Smaller Size**: ~7.6MB vs ~12MB+ for glibc static builds
- **Better Portability**: Works on ANY Linux distribution without modification
- **Cleaner Linking**: No glibc-specific extensions or fortified functions
- **Simpler Deployment**: Single binary, no library compatibility issues
**glibc Limitations:**
- Static builds still require dynamic loading for NSS (Name Service Switch)
- Fortified functions (`__*_chk`) don't exist in MUSL
- Larger binary size due to glibc's complexity
- May have compatibility issues across different glibc versions
## Build Process
### Prerequisites
- Docker installed and running
- Sufficient disk space (~2GB for Docker layers)
- Internet connection (for downloading dependencies)
### Quick Start
```bash
# Build MUSL static binary
./build_static.sh
# The binary will be created at:
# build/c_relay_static_musl_x86_64 (on x86_64)
# build/c_relay_static_musl_arm64 (on ARM64)
```
### What Happens During Build
1. **Alpine Linux Base**: Uses Alpine 3.19 with native MUSL support
2. **Static Dependencies**: Builds all dependencies with static linking:
- libsecp256k1 (Bitcoin cryptography)
- libwebsockets (WebSocket server)
- OpenSSL (TLS/crypto)
- SQLite (database)
- curl (HTTP client)
- zlib (compression)
3. **nostr_core_lib**: Builds with MUSL-compatible flags:
- Disables glibc fortification (`-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0`)
- Includes required NIPs: 001, 006, 013, 017, 019, 044, 059
- Produces static library (~316KB)
4. **c-relay Compilation**: Links everything statically:
- All source files compiled with `-static` flag
- Fortification disabled to avoid `__*_chk` symbols
- Results in ~7.6MB stripped binary
5. **Verification**: Confirms binary is truly static:
- `ldd` shows "not a dynamic executable"
- `file` shows "statically linked"
- Binary executes successfully
## Technical Details
### Dockerfile Structure
The build uses a multi-stage Dockerfile (`Dockerfile.alpine-musl`):
```dockerfile
# Stage 1: Builder (Alpine Linux)
FROM alpine:3.19 AS builder
- Install build tools and static libraries
- Build dependencies from source
- Compile nostr_core_lib with MUSL flags
- Compile c-relay with full static linking
- Strip binary to reduce size
# Stage 2: Output (scratch)
FROM scratch AS output
- Contains only the final binary
```
### Key Compilation Flags
**For nostr_core_lib:**
```bash
CFLAGS="-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -Wall -Wextra -std=c99 -fPIC -O2"
```
**For c-relay:**
```bash
gcc -static -O2 -Wall -Wextra -std=c99 \
-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 \
[source files] \
-lwebsockets -lssl -lcrypto -lsqlite3 -lsecp256k1 \
-lcurl -lz -lpthread -lm -ldl
```
### Fortification Issue
**Problem**: GCC's `-O2` optimization enables fortification by default, replacing standard functions with `__*_chk` variants (e.g., `__snprintf_chk`, `__fprintf_chk`). These are glibc-specific and don't exist in MUSL.
**Solution**: Explicitly disable fortification with:
- `-U_FORTIFY_SOURCE` (undefine any existing definition)
- `-D_FORTIFY_SOURCE=0` (set to 0)
This must be applied to **both** nostr_core_lib and c-relay compilation.
### NIP Dependencies
The build includes these NIPs in nostr_core_lib:
- **NIP-001**: Basic protocol (event creation, signing)
- **NIP-006**: Key derivation from mnemonic
- **NIP-013**: Proof of Work validation
- **NIP-017**: Private Direct Messages
- **NIP-019**: Bech32 encoding (nsec/npub)
- **NIP-044**: Modern encryption
- **NIP-059**: Gift Wrap (required by NIP-017)
## Verification
### Check Binary Type
```bash
# Should show "statically linked"
file build/c_relay_static_musl_x86_64
# Should show "not a dynamic executable"
ldd build/c_relay_static_musl_x86_64
# Check size (should be ~7.6MB)
ls -lh build/c_relay_static_musl_x86_64
```
### Test Execution
```bash
# Show help
./build/c_relay_static_musl_x86_64 --help
# Show version
./build/c_relay_static_musl_x86_64 --version
# Run relay
./build/c_relay_static_musl_x86_64 --port 8888
```
### Cross-Distribution Testing
Test the binary on different distributions to verify portability:
```bash
# Alpine Linux
docker run --rm -v $(pwd)/build:/app alpine:latest /app/c_relay_static_musl_x86_64 --version
# Ubuntu
docker run --rm -v $(pwd)/build:/app ubuntu:latest /app/c_relay_static_musl_x86_64 --version
# Debian
docker run --rm -v $(pwd)/build:/app debian:latest /app/c_relay_static_musl_x86_64 --version
# CentOS
docker run --rm -v $(pwd)/build:/app centos:latest /app/c_relay_static_musl_x86_64 --version
```
## Troubleshooting
### Docker Permission Denied
**Problem**: `permission denied while trying to connect to the Docker daemon socket`
**Solution**: Add user to docker group:
```bash
sudo usermod -aG docker $USER
newgrp docker # Or logout and login again
```
### Build Fails with Fortification Errors
**Problem**: `undefined reference to '__snprintf_chk'` or `'__fprintf_chk'`
**Solution**: Ensure fortification is disabled in both:
1. nostr_core_lib build.sh (line 534)
2. c-relay compilation flags in Dockerfile
### Binary Won't Execute
**Problem**: Binary fails to run on target system
**Checks**:
1. Verify it's truly static: `ldd binary` should show "not a dynamic executable"
2. Check architecture matches: `file binary` should show correct arch
3. Ensure execute permissions: `chmod +x binary`
### Missing NIP Functions
**Problem**: `undefined reference to 'nostr_nip*'` during linking
**Solution**: Add missing NIPs to the build command:
```bash
./build.sh --nips=1,6,13,17,19,44,59
```
## Deployment
### Single Binary Deployment
```bash
# Copy binary to server
scp build/c_relay_static_musl_x86_64 user@server:/opt/c-relay/
# Run on server (no dependencies needed!)
ssh user@server
cd /opt/c-relay
./c_relay_static_musl_x86_64 --port 8888
```
### SystemD Service
```ini
[Unit]
Description=C-Relay Nostr Relay (MUSL Static)
After=network.target
[Service]
Type=simple
User=c-relay
WorkingDirectory=/opt/c-relay
ExecStart=/opt/c-relay/c_relay_static_musl_x86_64

[Install]
WantedBy=multi-user.target
```
## Performance Comparison
| Metric | MUSL Static | glibc Static | glibc Dynamic |
|--------|-------------|--------------|---------------|
| Binary Size | 7.6 MB | 12+ MB | 2-3 MB |
| Startup Time | ~50ms | ~60ms | ~40ms |
| Memory Usage | Similar | Similar | Similar |
| Portability | ✓ Any Linux | ⚠ glibc only | ✗ Requires libs |
| Dependencies | None | NSS libs | Many libs |
## Best Practices
1. **Always verify** the binary is truly static before deployment
2. **Test on multiple distributions** to ensure portability
3. **Keep Docker images updated** for security patches
4. **Document the build date** and commit hash for reproducibility
5. **Store binaries** with architecture in filename (e.g., `_x86_64`, `_arm64`)
