On Virtuozzo7 jenkins we see a fail of criu-dev zdtm: ===================== Run zdtm/static/pthread_timers in ns ===================== Start test ./pthread_timers --pidfile=pthread_timers.pid --outfile=pthread_timers.out Run criu dump =[log]=> dump/zdtm/static/pthread_timers/112/1/dump.log ------------------------ grep Error ------------------------ (00.004817) netlink: Collect netlink sock 0x1cad6e21 (00.004821) netlink: Collect netlink sock 0x1cad6e22 (00.004831) Collecting pidns 9/112 (00.004886) No parent images directory provided (00.004903) Warn (criu/lsm.c:328): don't know how to suspend LSM 0 ------------------------ ERROR OVER ------------------------ Run criu restore 4: Old maps lost: set([]) 4: New maps appeared: set([u'7fe4c54ca000-7fe4c54cb000 ---p', u'7fe4c0000000-7fe4c0021000 rw-p', u'7fe4c0021000-7fe4c4000000 ---p', u'7fe4c54cb000-7fe4c5ccb000 rw-p']) ############# Test zdtm/static/pthread_timers FAIL at maps compare ############# https://ci.openvz.org/job/CRIU/job/CRIU-virtuozzo/job/criu-dev/8032/consoleFull First thing to mention is that this is not related to criu. I can manage to reproduce it with "--nocr", problem is that some mapping appears a bit later when we do pre-cr get_visible_state(). By debugging SIGEV_THREAD thread with gdb I can see that addresses from this unexpectedly appearing mapping are used by glibc here as "struct pthread *pd": clone() start_thread() timer_helper_thread() __pthread_create_2_1() So the mapping looks allocated by allocate_stack(), and it is only gets done after first timer trigger (we have glibc-2.17 on vz7): https://github.com/bminor/glibc/blob/release/2.17/master/nptl/sysdeps/unix/sysv/linux/timer_routines.c#L92 So let's wait at least 1 timer trigger so that memory outfit of the test become permanent and our check_visible_state zdtm check would not be false negative.
