As of the below commit, udp sockets bound to a specific address can
coexist with one bound to the any addr for the same port.
The commit also phased out the use of socket hashing based only on
port (hslot), in favor of always hashing on {addr, port} (hslot2).
The change broke the following behavior with disconnect (AF_UNSPEC):
server binds to 0.0.0.0:1337
server connects to 127.0.0.1:80
server disconnects
client connects to 127.0.0.1:1337
client sends "hello"
server reads "hello" // times out, packet did not find sk
On connect the server acquires a specific source addr suitable for
routing to its destination. On disconnect it reverts to the any addr.
The connect call triggers a rehash to a different hslot2. On
disconnect, add the same to return to the original hslot2.
Skip this step if the socket is going to be unhashed completely.

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.
