After commita88c9e4969("mptcp: do not block subflows creation on errors"), if a signal address races with a failing subflow creation, the subflow creation failure control path can trigger the selection of the next address to be announced while the current announced is still pending. The above will cause the unintended suppression of the ADD_ADDR announce. Fix the issue skipping the to-be-suppressed announce before it will mark an endpoint as already used. The relevant announce will be triggered again when the current one will complete.

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.
