PR_SET_MM_START_DATA, PR_SET_MM_END_DATA - modify kernel memory
map descriptor fields
Standard C library (libc, -lc)
#include <linux/prctl.h> /* Definition of PR_* constants */
#include <sys/prctl.h>
int prctl(PR_SET_MM, PR_SET_MM_START_DATA, unsigned long addr, 0L, 0L);
int prctl(PR_SET_MM, PR_SET_MM_END_DATA, unsigned long addr, 0L, 0L);
PR_SET_MM_START_DATA
Set the address above which initialized and uninitialized
(bss) data are placed. The corresponding memory area must
be readable and writable, but not executable or shareable.
PR_SET_MM_END_DATA
Set the address below which initialized and uninitialized
(bss) data are placed. The corresponding memory area must
be readable and writable, but not executable or shareable.
On success, 0 is returned. On error, -1 is returned, and errno
is set to indicate the error.
EINVAL addr is greater than TASK_SIZE (the limit on the size of
the user address space for this architecture).
EINVAL The permissions of the corresponding memory area are not
as required.
