If the end position of a GETFSMAP query overlaps an allocated space and we're using the free space info to generate fsmap info, the akeys information gets fed into the fsmap formatter with bad results. Zero-init the space. Reported-by: syzbot+090ae72d552e6bd93cfe@syzkaller.appspotmail.com Signed-off-by: Darrick J. Wong <djwong@kernel.org>
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.
