Subject: [PATCH net 0/5] vsock: Transport reassignment and error handling
 issues

Series deals with two issues:
- socket reference count imbalance due to an unforgiving transport release
  (triggered by transport reassignment);
- unintentional API feature, a failing connect() making the socket
  impossible to use for any subsequent connect() attempts.

      vsock: Keep the binding until socket destruction
      vsock: Allow retrying on connect() failure
      vsock/test: Introduce vsock_bind()
      vsock/test: Add test for UAF due to socket unbinding
      vsock/test: Add test for connect() retries
