This change adds an internal function to store/retrieve local addrs announced by userspace PM implementations to/from its kernel context. The function addresses the requirements of three scenarios: 1) ADD_ADDR announcements (which require that a local id be provided), 2) retrieving the local id associated with an address, and also where one may need to be assigned, and 3) reissuance of ADD_ADDRs when there's a successful match of addr/id. The list of all stored local addr entries is held under the MPTCP sock structure. Memory for these entries is allocated from the sock option buffer, so the list of addrs is bounded by optmem_max. The list if not released via REMOVE_ADDR signals is ultimately freed when the sock is destructed.

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.
