Since we now build with -Wvla, any use of VLA throws a warning. Including this test, so... maybe we should just remove the test? lib/test_ubsan.c: In function 'test_ubsan_vla_bound_not_positive': lib/test_ubsan.c:48:2: warning: ISO C90 forbids variable length array 'buf' [-Wvla] For the out-of-bounds test, switch to non-VLA setup. lib/test_ubsan.c: In function 'test_ubsan_out_of_bounds': lib/test_ubsan.c:64:2: warning: ISO C90 forbids variable length array 'arr' [-Wvla] Link: http://lkml.kernel.org/r/20190113183210.56154-1-olof@lixom.net Signed-off-by: Olof Johansson <olof@lixom.net> Acked-by: Dmitry Vyukov <dvyukov@google.com> Cc: Colin Ian King <colin.king@canonical.com> Cc: Jinbum Park <jinb.park7@gmail.com> Cc: Andrey Ryabinin <aryabinin@virtuozzo.com> Cc: Kees Cook <keescook@chromium.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.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.
