Revision cf92251dc52d2dfae6c6adaeae8b12ea50686946 authored by Rik van Riel on 12 July 2017, 21:36:36 UTC, committed by Linus Torvalds on 12 July 2017, 23:26:03 UTC
When RLIMIT_STACK is, for example, 256MB, the current code results in a gap between the top of the task and mmap_base of 256MB, failing to take into account the amount by which the stack address was randomized. In other words, the stack gets less than RLIMIT_STACK space. Ensure that the gap between the stack and mmap_base always takes stack randomization and the stack guard gap into account. Obtained from Daniel Micay's linux-hardened tree.
