645414cc9f add 1 byte overflow tests 2022-01-03 21:20:15 -05:00
Daniel Micay
13a1f578cb use calculated size for overflow tests 
This greatly reduces how much these tests depend on hard-wired knowledge
about the size classes.

acda766e2c fix small allocation canary overwrite test 
Overwriting one byte of a canary with 0 has a 1/256 chance of not
triggering the expected failure.

c6af50d088 use unsigned for ffzl definition 
This makes more sense and avoids clang tidy conversion warnings.

8ae78237ae avoid unnecessarily mixing 32-bit and 64-bit ints 
It's ever so slightly faster to stick to stick to 64-bit arithmetic and
it avoids clang tidy being unhappy about the implicit widening.

3f8e9d3184 make MREMAP_MOVE_THRESHOLD into size_t constant 
This avoids a clang-tidy warning and is a bit cleaner.

1e526fc36b disable incredibly impractical clang-tidy check 
bugprone-easily-swappable-parameters is completely impractical for real
world usage. It's a reasonable thing to consider as part of API design
but it mostly applies to having APIs taking a lot of parameters. It's
unreasonable to disallow APIs simply taking 2 integer parameters even as
a loose guideline.

ffdf7b1ee1 Make the testsuite work for read-after-free 
This commit makes the testsuite fail if
the read-after-free tests are failing, instead
of simply printing some info.

de7a3b6e5a enable sized deallocation for sized deletion test 
Clang doesn't currently enable sized deallocation by default like GCC.

cff1d6d4b5 Add a test to prove that hardened_malloc handles too-large-to-be-true allocations 
This pattern, used by https://github.com/kaist-hacking/HardsHeap,
uncovered bugs in other memory allocators.

4ccd6f16df always enable C++17 
The safe_flag check doesn't work properly for C++ flags with Clang so
this wasn't getting enabled despite the conditional compilation being
removed from the code, leading to breaking Clang builds.

a33d2ca97d Fix CPPFLAGS in test Makefile 
In particular, the _GNU_SOURCE feature test macro needs to be set in
order to correctly define mmap(2) flags such as MAP_ANONYMOUS.
Otherwise, compilation of some test files fails when CPPFLAGS is not
defined in the initial user environment, as Make then does not export it
from the root Makefile to the sub-make.
