libcriu.so used to have the SONAME
$ readelf -d lib/c/libcriu.so | grep SONAME
0x000000000000000e (SONAME) Library soname: [libcriu.so.1]
The recent changes to libcriu (removed and added functions, changes from
`char *`-args to `const char *`) are breaking ABI and API. This requires
a new SONAME of 2. This patch changes the SONAME to 2:
$ readelf -d lib/c/libcriu.so | grep SONAME
0x000000000000000e (SONAME) Library soname: [libcriu.so.2]

So here it is -- the release with lots of new stuff and bugfixes.
Mainly, the new code is for integration with Docker and to support
modern hardware.

We've slowed down a little, but still new features and bugfixes appear.
This time we've improved lazy migration, completed SCM messages support,
added nesting netns support (now we have two of them -- net and mnt)
and did many small fixes here and there.

This time we shifted the update one month, due to the amount of
changes not being very big. And got pretty big update, including
a set of bugfixes and new functionality.

As usually -- many bugfixes and several new features. The s390x stuff
goes well too. The most tempting new feature is the ability to dump
and restore files sent over unix sockets (SCM_RIGHTS).

So, the long-running task with lazy restore is (almost) finished :) Some
issues are still to be resolved, but the heaviest lift has been done.
Another notable thing is VDSO C/R rework. It's now more robust and fast.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
The biggest new thing this time is s390x arch support!
Also we have several improvements and a set of bugfixes
as usual.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
Most of the changes this time are preparation for future
new features and optimizations, that hasn't yet been well
tested and polished.
However, we have several new features. The most important
one is the --tcp-close option to help migration of Docker
containers, that constantly change their IP address.
And, as usually, a set of bugfixes.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
This is a hot-fix with a regression fix and an urgent
support for the latest-n-greatest kernel API change.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
This is the no-new-features release :) We have several bugfixes,
memory restore optimization and a little bit more.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, we've done a HUUGE rework in this release, that's why it's 3.0.
Two biggest changes are:
* Compel library -- the framwork for parasite code injection.
* 32bit x86 support. Note, that it's neither x32 support, not 32-bit
criu. It's purely the ability to dump 32-bit tasks on 64-bit host.
With compel at hands the 'criu exec' is removed.
Main set of kudos go to Cyrill and Dima for this heavy lifting :)
Other things include shutdown-ed UDP sockets, bind-mounts to external
bind mounts, ASAN, extentions to RPC, rework of SysVIPC shmem dump
format and some bugfixes and beautifications in CRIT.

The compel component is a replacement for several aspects of CRIU
functionality: binary blobs generation for PIE parasite/restore code,
and a library for parasite code injection and execution (to be implemented).
In the commit we rather shuffle compel into own directory and
use it for
1) Fetching cflags when compiling PIE blobs
2) Use its "piegen" functionality to generate blobs themselves.

- page-server start via RPC
- Fedora build

This is a bugfix-mostly release. Interesting new features include
the huge rework of files restoring engine which fixed us bugs we
haven't seen in reality :) but have proven they exist. Als this
rework opens the way for scm-rigts c/r we need for nginx.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, this time we had TCP transitional states support, but it was
in semi-finished libsoccr library :) And in order to have the TCP
C/R fixed we fixed the library and are now ready to release them
both.
Said that, two main features of the Waxwing release are
* libsoccr -- the library for TCP sockets C/R
* TCP transitional states C/R
Also we have a set of bugfixes, caught performance issue on Xen
and a little bit more.

For now build the .a library not to produce criu wrappers.
Next version should include the .so library as well.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
This is quite a tiny bigfix mostly release.
One interesting thing, though, is that CRIU can now be built with
clang on all the supported architectures :)
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, this time we've mostly have a lot of code rework for
compel. A big portion of it is still in criu-dev, but
some has been merged into master.
Other than this and a bunch of bugfixes -- .config file,
support for Tun-Tap devices and deprecation of several
CLI and RPC options by the --external one.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
Not a lot this time, just a bunch of bugfixes and improvements.
A lot has happened in -dev branch around compel, hopefully the
next release will have it.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, this time we have quite a lot of new features for a monthly
release cadence, including --leave-stopped on restore, TMEM for
PPC and shmem changes tracking.
Also bugfixes, of course, and a little bit more deprecations.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
Bug-fix mostly release.
We've also came very close in -dev branch to having x86 32bit
support, so hopefully we'll have it in 2.6/2.7. Lazy restore
now in test-able state, but still we want kernel patches to
leave maintainer's tree, so we still wait.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
This time we have a bunch of new features, such as more
cgroup stuff, AutoFS, coredump out of images, etc.
Virtuozzo guys have released vz7-rtm, and fixed a lot
of bugs in criu while doing it :)
Plus some ancient stuff removed.
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, we have some nice new features, again aimed at better integration,
also have massive restorer blob preparation rework and several nasty
bugfixes in mounts code.

We use in our PCS7 packaging and I think it's
suitable for everything else as well.

This is bugfix mostly release again.
Also did some tunes for better integration with OpenVZ (action scripts),
updated to support newer kernels improvements and removed pagemap greedy
mode and --namespaces option.

Here's the first once-a-month release with whatever is there in
the master branch. We have quite a few new features, but a lot of
bugifxes :)
Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
So, here it is. We planned not only to re-shuffle the code, but
also to provide compel thing to people, but have only managed to
do the former. OK, the compel then would go in 2.1 :)
But, we also change the dev-n-release model, so from now on we
have 2 branches and release stable one every month to show new
stuff earlier.
Have fun!
