configname: CONFIG_ARCH_MMAP_RND_COMPAT_BITS
Linux Kernel Configuration
└─>General architecture-dependent options
└─>Number of bits to use for ASLR of mmap base address for compatible applications
In linux kernel since version 4.1 (release Date: 2015-06-21)
This value can be used to select the number of bits to use to
determine the random offset to the base address of vma regions
resulting from mmap allocations for compatible applications This
value will be bounded by the architecture's minimum and maximum
supported values.
This value can be changed after boot using the
/proc/sys/vm/mmap_rnd_compat_bits tunable
