Wang Long 6b4a35fc19 lib/test_kasan.c: make kmalloc_oob_krealloc_less more correctly
In kmalloc_oob_krealloc_less, I think it is better to test
the size2 boundary.

If we do not call krealloc, the access of position size1 will still cause
out-of-bounds and access of position size2 does not.  After call krealloc,
the access of position size2 cause out-of-bounds.  So using size2 is more
correct.

Andrey Ryabinin 3f15801cdc lib: add kasan test module
This is a test module doing various nasty things like out of bounds
accesses, use after free.  It is useful for testing kernel debugging
features like kernel address sanitizer.

It mostly concentrates on testing of slab allocator, but we might want to
add more different stuff here in future (like stack/global variables out
of bounds accesses and so on).
