If buf[-1] just happens to hold the byte 0x0A, then nread can wrap around to (size_t)-1, leading to invalid memory accesses. This has caused segmentation faults when trying to build the latest kernel snapshots for i686 in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1592374 Signed-off-by: Jerry James <loganjerry@gmail.com> [alexpl@fedoraproject.org: reformatted patch for submission] Signed-off-by: Alexander Ploumistos <alexpl@fedoraproject.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
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.
