[ Upstream commitf5f27b79ea] The header of the message to send can be changed if the response is longer than the request: - 1st word, the header is sent - the remaining words of the message are sent - the response is received asynchronously during the execution of the loop, changing the size field in the header - the for loop test the termination condition using the corrupted header It is the case for the API build_info which has just a header as request but 3 words in response. This issue is fixed storing the header locally instead of using a pointer on it.

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.
