+# SSL Connection Error Handling Tests
+
+This directory contains comprehensive tests for SSL connection error handling, specifically addressing the "Bad file descriptor" errors that occur when nodes reboot while using client encryption.
+
+## Background
+
+### Issue
+When using client encryption and nodes reboot, the driver reported errors like:
+```
+cassandra.connection.ConnectionShutdown: [Errno 9] Bad file descriptor
+```
+
+The issue occurred because:
+1. A connection is forcefully closed (e.g., due to node reboot)
+2. Parallel operations attempt to read/write to the closed socket
+3. This results in "Bad file descriptor" errors
+4. The original cause of the connection closure could be lost
+
+See: https://github.com/scylladb/python-driver/issues/614
+
+### Solution
+The driver already has proper error handling via the `last_error` mechanism in the `Connection` class. When a connection becomes defunct, the error that caused it is stored in `last_error` and included in subsequent `ConnectionShutdown` exception messages.
+
+This test suite verifies that this mechanism works correctly across all SSL error scenarios.
+
+## Test Files
+
+### Unit Tests (`test_ssl_connection_errors.py`)
+14 unit tests that mock SSL connection failures:
+
+1. **Basic SSL Socket Errors**
+   - `test_ssl_socket_bad_file_descriptor_on_send`: Simulates EBADF during send
+   - `test_ssl_socket_bad_file_descriptor_on_recv`: Simulates EBADF during recv
+   - `test_ssl_socket_broken_pipe_error`: Simulates EPIPE (broken pipe)
+   - `test_ssl_socket_connection_aborted_error`: Simulates ECONNABORTED
+   - `test_ssl_socket_errno_enotconn`: Simulates ENOTCONN
+
+2. **SSL-Specific Errors**
+   - `test_ssl_connection_error_during_handshake`: SSL handshake failures
+   - `test_ssl_unwrap_error_on_close`: SSL unwrap errors during close
+
+3. **Race Condition Tests**
+   - `test_concurrent_operations_on_closed_ssl_socket`: Multiple threads using closed socket
+   - `test_parallel_send_on_defuncting_connection`: Thread trying to send while connection defuncts
+   - `test_node_reboot_scenario`: Complete node reboot simulation
+
+4. **Error Preservation Tests**
+   - `test_multiple_error_scenarios_last_error_preserved`: Verifies first error is preserved
+   - `test_wait_for_responses_includes_ssl_error`: Error included in wait_for_responses
+   - `test_ssl_error_on_closed_connection_send_msg`: Error included in send_msg
+
+### Integration Tests (`test_ssl_connection_failures.py`)
+4 integration tests with actual connection implementations:
+
+1. **AsyncioConnection Tests** (2 tests)
+   - Socket error preservation
+   - Connection reset handling
+
+2. **Error Message Quality Tests** (2 tests)
+   - Error message includes root cause
+   - Multiple errors preserve first error
+
+## Running the Tests
+
+### Unit Tests Only
+```bash
+pytest tests/unit/test_ssl_connection_errors.py -v
+```
+
+### Integration Tests (requires running cluster)
+```bash
+pytest tests/integration/standard/test_ssl_connection_failures.py -v
+```
+
+### All Connection Tests
+```bash
+pytest tests/unit/test_connection.py tests/unit/test_ssl_connection_errors.py -v
+```
+
+## Test Coverage
+
+The tests verify:
+- ✅ Original error is captured in `last_error` field
+- ✅ `ConnectionShutdown` exceptions include root cause
+- ✅ Concurrent operations see original error, not just "Bad file descriptor"
+- ✅ First error is preserved when multiple errors occur
+- ✅ Mechanism works across different error types (EBADF, EPIPE, ECONNRESET, etc.)
+- ✅ AsyncioConnection handles errors correctly
+
+## Code Changes
+
+**No driver code changes were needed**. The existing error handling mechanism was already correct. These tests document and verify the expected behavior.
+
+## Key Implementation Details
+
+When a connection error occurs:
+
+1. The error is caught in the reactor's `handle_error()`, `handle_write()`, or `handle_read()` method
+2. `defunct(exc)` is called with the exception
+3. `defunct()` stores the exception in `self.last_error`
+4. Subsequent operations check `is_defunct` and raise `ConnectionShutdown` with the original error
+
+Example from `connection.py`:
+```python
+def send_msg(self, msg, request_id, cb, ...):
+    if self.is_defunct:
+        msg = "Connection to %s is defunct" % self.endpoint
+        if self.last_error:
+            msg += ": %s" % (self.last_error,)  # Include original error
+        raise ConnectionShutdown(msg)
+```
+
+## Contributing
+
+When adding new connection error handling code:
+1. Add corresponding tests to `test_ssl_connection_errors.py`
+2. Ensure `last_error` is set when connections become defunct
+3. Verify error messages include the root cause
+4. Test concurrent operation scenarios
