The current 'tipc_wait_for_connect()' function does a wait-loop for the condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket connecting has done. However, when the condition is met, it returns '0' even in the case the connecting is actually failed, the socket state is set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..). This results in a wrong return code for the 'connect()' call from user, making it believe that the connection is established and go ahead with building, sending a message, etc. but finally failed e.g. '-EPIPE'. This commit fixes the issue by changing the wait condition to the 'tipc_sk_connected(sk)', so the function will return '0' only when the connection is really established. Otherwise, either the socket 'sk_err' if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
