When we can't stat socket name with ENOENT errno this means, that the socket is bound and unlinked. Don't drop the whole socket info, just treat it as nameless. Signed-off-by:Pavel Emelyanov <xemul@parallels.com>

This test does a few operation in a loop * create a mapping with random flags * touch a few pages in a new mapping, if it's writable This test has two processes. The second process goes a predefined value of steps behind the first one. When we need to check the result, we stop the first process, wait until the second process come to the same point and compare these processes. The processes are dumped in different states, but at the end both processes must be in the same state. bash -x test/zdtm.sh -s -i 5 -r transition/maps007 ...

If we write a page into image and punch it from parnet, checking only one level down is not enough -- the iovec can reside deeper. That said, make the hole punching be recursive. Signed-off-by:

The bugfix period after 1.1-rc1 seems to be over. With this version we pin down the API to plugins and libcriu.so. Next steps will be tied with live-migration usecase for CRIU :) Signed-off-by:

When writing pagemaps to page-server we want both page-*.img and pagemap-*.img to be on remote host. But the subsequent pre-dump/dump with parent images will try to access pagemap-*img-s to check for hole dumped being present in it. To handle this, move checks for hole being backed by something in parent into page-local-xfer. In case of page-server dump it will be page-server who will check the holes when writing them.

because eof in restore means that we don't have "must have" data, so it mean error exit, but in dedup, it's ok not to have data we seek, so we continue returning normally also it's used that if off < pr-cvaddr then no eof happened and if eof happened then off >= pr-cvaddr(then return of seek_pagemap_page is 0) Signed-off-by:

The feedback we got helped us to improve several issues all over the criu code. And we have some more stuff to get fixed before we can make a good release. That said, let's go ahead with the -rc2. Signed-off-by: -

While doing pre-dump we don't do proper VDSO fixups, thus at this stage we may fail the should_dump_page() checks -- it will tread VDSO pages are 'regular' and may skip dumping some of them. This is not bad as is, but the subsequent dump will properly spot VDSO are and will try to dump _all_ pages from it. And if checks for soft-dirty will report that some pages are clean, dump will try to locate those in parent images and would fail. Acked-by:

If we're doing the pre-dump command we don't have the tasks' IDs collected, so we have the current_ns_mask uninitilized. Thus we create parasite transport socket in criu's namespace always and pre-dump of task, sitting in foreing net namespace may hang. From the "performance" point of view, it's easier to always create transport socket in victim's namespace, rahter than getting the current_ns_mask. Signed-off-by:

There is no way in options to make page server send data to another page server -- the address/port ones would apply to local page server. Thus there is no need to open generic xfer in page server, just go to local one and avoid confusion Signed-off-by: -

While timestamps can be handy, they clutter output for normal users. Let's print them only when verbosity (-v) is increased from default. Currently, default is 2 (-vv) so for timestamps one should use -vvv or -v3. Alternatively, we could introduce a separate --timestamps option. Personally, I find it more handy for timestamps to be tied to log level. Signed-off-by:

This is a slight refactoring of commit 7de96526, which just simplifies initialization of 'off' variable, and adds the comment why we do so. Should make the next patch easier to read. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

Current description of -v[vvv] was taken from criu-log.h comments and describes specific log levels used by pr_* functions. The problem is -vX includes all previous X-1, X-2... levels. Say, -vvvv description says "debug only", while in fact it is not "only". Fix accordingly. Also, removed -v0 description as it is useless. What -v0 in fact does is it sets the log level to default -- same as if -vXXX is not used. In addition, change a delimiter between option alternatives from comma to a vertical bar in criu --help output, to be in line with the rest of usage output. Signed-off-by:
