The code that made aligned_alloc work with the 4-byte heap headers was requesting a block of the correctly padded size, and correctly aligning the output buffer within that memory, but it was using the UNALIGNED chunk size for the buffer as the final size of the block with splitting off the unused suffix. So the final chunk in the buffer was could be incorrectly returned to the heap and reused, leading to overlap. Compute the chunk size of the output buffer based on the already-aligned output pointer instead. Initial investigation and fix from Andy Ross <andrew.j.ross@intel.com>. I reworked his fix, created a test case, and stolen his commit log. Signed-off-by: Nicolas Pitre <npitre@baylibre.com> |
