This patch fixes a bug where the sequence numbers of a socket created using TCP repair functionality are lower than set after connect is called. This occurs when the repair socket overlaps with a TIME-WAIT socket and triggers the re-use code. The amount lower is equal to the number of times that a particular IP/port set is re-used and then put back into TIME-WAIT. Re-using the first time the sequence number is 1 lower, closing that socket and then re-opening (with repair) a new socket with the same addresses/ports puts the sequence number 2 lower than set via setsockopt. The third time is 3 lower, etc. I have not tested what the limit of this acrewal is, if any. The fix is, if a socket is in repair mode, to respect the already set sequence number and timestamp when it would have already re-used the TIME-WAIT socket.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
