Hi! Added "has_log_level = true" to test.c, so "log_level = 4" would have effect. Also added log_level to test.py, for symmetry with test.c. Signed-off-by:

The maximal size which may be used in the kernel for sending TCP data on restore is varies depending on how many memory installed on the system, moreover the memory allocated for "read queue" is bigger than used for "write queue". Thus when we checkpointed a big slab of data we need to figure out which size is allowed for sending data on restore. For this we read /proc/sys/net/ipv4/tcp_[wmem|rmem] on restore and calculate the size needed, then we simply chop data to segements and send it in a loop. Typical output on restore is something like | (00.013001) 30110: TCP queue memory limits are 2097152:3145728 https://bugzilla.openvz.org/show_bug.cgi?id=2751 [xemul: moved stuff to kerndat.c] Reported-by:

We need to detect parasite crashes to not hangs on socket operations. CRIU ptraces parasite. So if it crashes, SIGCHLD is received. If a parasite daemon crashed, we can to do nothing. The state of current process can't be restored, because we can't to drop the signal. The state of other processes are consistent. Probably the best choise in this case is to exit. Signed-off-by:

We are going to detect parasite crashes. For that we are goint to check all unwaited processes in SIGCHLD handler. cr_system blocks SIGCHLD and unblocks it after waiting a target process. Signed-off-by:
