vma_entry contains shmid and all shared memory are dumped in own files. The most interesting thing is restore. A maping is restored by process with the smallest pid. The mamping is created before executing restorer. We map a full mapping and restore it's conten, then we open a file from /proc/pid/map_files and store a descriptor in vma_info. The mapping is unmaped. Now we can map any region of this mapping in the restorer. We use this trick, because a target process may have this mapping in some places and the restorer has not function to open proc files. v2: fix error hangling xemul: Fixed static-s and args for cr_dump_shmem Signed-off-by: Andrey Vagin <avagin@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com> |
