Make sure that the memory allocators are behaving as expected in the face of overflows of multiplied arguments or when using the array_size()-family helpers. Example output of new tests (with the expected __alloc_pages_slowpath and vmalloc warnings about refusing giant allocations removed): [ 93.062076] test_overflow: kmalloc detected saturation [ 93.062988] test_overflow: kmalloc_node detected saturation [ 93.063818] test_overflow: kzalloc detected saturation [ 93.064539] test_overflow: kzalloc_node detected saturation [ 93.120386] test_overflow: kvmalloc detected saturation [ 93.143458] test_overflow: kvmalloc_node detected saturation [ 93.166861] test_overflow: kvzalloc detected saturation [ 93.189924] test_overflow: kvzalloc_node detected saturation [ 93.221671] test_overflow: vmalloc detected saturation [ 93.246326] test_overflow: vmalloc_node detected saturation [ 93.270260] test_overflow: vzalloc detected saturation [ 93.293824] test_overflow: vzalloc_node detected saturation [ 93.294597] test_overflow: devm_kmalloc detected saturation [ 93.295383] test_overflow: devm_kzalloc detected saturation [ 93.296217] test_overflow: all tests passed Signed-off-by: Kees Cook <keescook@chromium.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.
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.
