Address issues where DMSG client utilities would not respond to Ctrl+C: - Use signal-aware context for dmsgC.Serve() instead of context.Background() in internal/cli, pkg/direct, and dmsgpty-host - Add context cancellation check in dmsg-socks5 accept loop to properly exit on signal - Implement graceful HTTP server shutdown with 5-second timeout in dmsghttp - Ensure dmsgC.Close() is called via defer in dmsgpty-host for proper cleanup - Add WaitGroup wait in direct client stop function for clean goroutine shutdown - Document temporary kill.go workaround for verification testing These changes ensure client utilities properly respond to interrupt signals without requiring multiple Ctrl+C presses.
Protect concurrent access to sm.yamux and sm.smux fields with sm.mutx lock to prevent data races when Close() or Ping() are called while session is being initialized. The race occurred when: - handleSession() writes to dSes.sm.yamux (server.go:242) while holding the lock - Close() reads sc.sm.yamux (session_common.go:187-188) without holding the lock - A goroutine can call Close() concurrently during session setup Changes: - Add sm.mutx.Lock() protection in Close() method - Add sm.mutx.RLock() protection in Ping() method for consistency
