Quoting Oren Laadan (orenl@xxxxxxxxxxxxxxx): > Basic checkpoint-restart [C/R]: v8 adds support for "external" checkpoint > and improves documentation. Older announcements below. The following test-program seems to reliably trigger a bug. Run it in a new set of namespaces, i.e. ns_exec -cmpiuU ./runme > /tmp/o then control-c it. The second time I do that, I get the dcache.c:666 BUG(). #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <unistd.h> #include <sys/syscall.h> #define __NR_checkpoint 333 int main (int argc, char *argv[]) { pid_t pid = getpid(); int ret; close(0); close(2); ret = syscall (__NR_checkpoint, pid, STDOUT_FILENO, 0); if (ret < 0) perror ("checkpoint"); else printf ("checkpoint id %d\n", ret); sleep(200); return (ret > 0 ? 0 : 1); } -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
