Q1 and Q2 are numbers with *maximum* length of 384 bytes. If the
calculated length of Q1 and Q2 is less than 384 bytes, things will
go wrong.
E.g. if Q2 is 383 bytes, then
1. The bytes of q2 are copied to sigstruct->q2 in calc_q1q2().
2. The entire sigstruct->q2 is reversed, which results it being
256 * Q2, given that the last byte of sigstruct->q2 is added
to before the bytes given by calc_q1q2().
Either change in key or measurement can trigger the bug. E.g. an
unmeasured heap could cause a devastating change in Q1 or Q2.
Reverse exactly the bytes of Q1 and Q2 in calc_q1q2() before returning
to the caller.

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.
