      fsnotify: merge fanotify mark image into fanotify image (v3) · c4a8dd17
      Andrey Vagin authored 
      All marks are collected in a list and then they are written in
the fanotify image as a repeated field.

This images merge reduces the amount of image files criu
generates and may simplify the fix of mentioned above issue

v2: don't leak fe.mark_entry
v3: save the original order of marks

      fsnotify: merge inotify wd image into inotify image (v4) · a10907a1
      Andrey Vagin authored 
      All watch descriptors are collected in a list and then
they are written in inotify image as a repeated field.

This images merge reduces the amount of image files criu
generates and may simplify the fix of mentioned above issue.

v2: use free_inotify_wd_entry() instead of xfree in dump_one_inotify()
v3: don't leak ie.wd_entry
v4: save the original order of watchers

      service: Add ability to inherit page server socket · 7058714f
      Pavel Emelyanov authored 
      The swrk action is turning out to be a cool thing. We can
spawn criu with swrk action with some FD being open, then
ask for dump/pre-dump/page-server telling it that some
descriptor it needs is "out there".

This patch lets us specify that the page server communication
channel is already in criu's fdtable.

TODO: teach regular service to accept fd via service socket.

      plugin: Rework plugins API, v2 · 3146f583
      Cyrill Gorcunov authored 
      Here we define new api to be used in plugins.

 - Plugin should provide a descriptor with help of
   CR_PLUGIN_REGISTER macro, or in case if plugin require
   no init/exit functions -- with CR_PLUGIN_REGISTER_DUMMY.

 - Plugin should define a plugin hook with help of
   CR_PLUGIN_REGISTER_HOOK macro.

 - Now init/exit functions of plugins takes @stage
   argument which tells plugin which stage of criu
   it's been called on dump/restore. For exit it
   also takes @ret which allows plugin to know if
   something went wrong and it needs to cleanup
   own resources.

The idea behind is to not limit plugins authors with names
of functions they might need to use for particular hook.

Such new API deprecates olds plugins structure but to keep
backward compatibility we will provide a tiny layer of
additional code to support old plugins for at least a couple
of release cycles.

For example a trivial plugin might look like

 | #include <sys/types.h>
 | #include <sys/stat.h>
 | #include <fcntl.h>
 | #include <libgen.h>
 | #include <errno.h>
 |
 | #include <sys/socket.h>
 | #include <linux/un.h>
 |
 | #include <stdio.h>
 | #include <stdlib.h>
 | #include <string.h>
 | #include <unistd.h>
 |
 | #include "criu-plugin.h"
 | #include "criu-log.h"
 |
 | static int dump_ext_file(int fd, int id)
 | {
 |	pr_info("dump_ext_file: fd %d id %d\n", fd, id);
 |	return 0;
 | }
 |
 | CR_PLUGIN_REGISTER_DUMMY("trivial")
 | CR_PLUGIN_REGISTER_HOOK(CR_PLUGIN_HOOK__DUMP_EXT_FILE, dump_ext_file)

      criu: Version 1.3 · c716f6b8
      Pavel Emelyanov authored 
      It's been a long delay since 1.2, but we did it :)

The greatest new acheivement is finally support for Docker
and LXC on CRIU side. Some work is still to be don on the
other, but here in CRIU everything is ready.

Another notable things are AArch64 support and, of course,
a lot of bugfixes.

Further plan is to make releases be not so rare :)
