Allow opt.tcache_max to accept small size classes. Previously all the small size classes were cached. However this has downsides -- particularly when page size is greater than 4K (e.g. iOS), which will result in much higher SMALL_MAXCLASS. This change allows tcache_max to be set to lower values, to better control resources taken by tcache. 2020-10-22 10:47:57 +08:00			`#!/bin/sh`

Implement use-after-free detection using junk and stash. On deallocation, sampled pointers (specially aligned) get junked and stashed into tcache (to prevent immediate reuse). The expected behavior is to have read-after-free corrupted and stopped by the junk-filling, while write-after-free is checked when flushing the stashed pointers. 2021-10-19 08:33:15 +08:00			`export MALLOC_CONF="tcache_max:1024,lg_san_uaf_align:-1"`
