[ Upstream commit5b0b9e4c2c] In tcp_create_openreq_child we adjust tcp_header_len for md5 using the remote address in newsk. But that address is still 0 in newsk at this point, and it is only set later by the callers (tcp_v[46]_syn_recv_sock). Use the address from the request socket instead. Fixes:cfb6eeb4c8("[TCP]: MD5 Signature Option (RFC2385) support.")

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.
