Michał Cłapiński 70c8c12c64 compel: don't mmap parasite as RWX ... Some kernels have W^X mitigation, which means they won't execute memory blocks if that memory block is also writable or ever was writable. This patch enables CRIU to run on such kernels. 1. Align .data section to a page. 2. mmap a memory block for parasite as RX. 3. mprotect everything after .text as RW. Signed-off-by: Michał Cłapiński <mclapinski@google.com>		2021-09-03 10:31:00 -07:00
