commit a71d0908e32f3dd41e355d83eeadd44d94811fd6 upstream.
The helper waiting for a listener port can match any socket whose
hexadecimal representation of source or destination addresses
matches that of the given port.
Additionally, any socket state is accepted.
All the above can let the helper return successfully before the
relevant listener is actually ready, with unexpected results.
So far I could not find any related failure in the netdev CI, but
the next patch is going to make the critical event more easily
reproducible.
Address the issue matching the port hex only vs the relevant socket
field and additionally checking the socket state for TCP sockets.

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.
