Matthieu Baerts f4480eaad4 selftests: mptcp: add missing join check
commit 857898eb4b upstream.

This function also writes the name of the test with its ID, making clear
a new test has been executed.

Without that, the ADD_ADDR results from this test was appended at the
end of the previous test causing confusions. Especially when the second
test was failing, we had:

  17 signal invalid addresses     syn[ ok ] - synack[ ok ] - ack[ ok ]
                                  add[ ok ] - echo  [ ok ]
                                  add[fail] got 2 ADD_ADDR[s] expected 3

In fact, this 17th test was OK but not the 18th one.

Now we have:

  17 signal invalid addresses     syn[ ok ] - synack[ ok ] - ack[ ok ]
                                  add[ ok ] - echo  [ ok ]
  18 signal addresses race test   syn[fail] got 2 JOIN[s] syn expected 3
   - synack[fail] got 2 JOIN[s] synack expected
   - ack[fail] got 2 JOIN[s] ack expected 3
                                  add[fail] got 2 ADD_ADDR[s] expected 3

[ Conflict in mptcp_join.sh, because commit 86e39e0448 ("mptcp: keep
  track of local endpoint still available for each msk") is not in this
  version and changed the context. The same line can still be applied at
  the same place. ]

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.
