[ Upstream commit 22a8118d329334833cd30f2ceb36d28e8cae8a4f ]
After allocation, output and decomp_output both point to memory chunks of
size COMP_BUF_SIZE. Then, only the first bytes are zeroed out using
sizeof(COMP_BUF_SIZE) as parameter to memset(), because
sizeof(COMP_BUF_SIZE) provides the size of the constant and not the size of
allocated memory.
Instead, the whole allocated memory is meant to be zeroed out. Use
COMP_BUF_SIZE as parameter to memset() directly in order to accomplish
this.

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.
