[PATCH 0/3] properly account for stack randomization and guard gap

2017-06-22 Thread riel
When RLIMIT_STACK is larger than the minimum gap enforced by mmap_base(), it is possible for the kernel to place the mmap area where the stack wants to grow, resulting in the stack not being able to use the space that should have been allocated to it through RLIMIT_STACK. This series ensures that
