There can be a more sophisticated security policy, but right now generic non-root user doesn't have any bits in there, so requiring them to be zero is a sane starting point. Signed-off-by:Pavel Emelyanov <xemul@parallels.com>

There's ... a number of places where we want to do something with /proc/self/fd/%d path. Each time we guess buffer size that is enough for this. Make standard constant for this and save some space on stack and drop args for some functions. Signed-off-by: -

CRIU puts wd-s for one inotify in one row (one after another), so when collecting next wd, we can find the ify to attach them to faster. Signed-off-by: -
Pavel Emelyanov authored
The inotify_add_watch generates wd-s one-by one. We cannot request for one, thus we call this syscall till the required wd is generated. Thus, if we want to restore several wd-s for an inotify, we have to put them in ascending order. Otherwise we may restore watch with higher wd earlier and will thus not be able to generate the lower wd in a reasonable time. Signed-off-by: -

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:
