Unnamed unix sockets created with socketpair() systemcall can be dumped and restored.
For dump socketpair put inode of this socket in <code>--ext-unix-sk</code> option, for example:
<code>
criu dump -D images -o dump.log -v4 --ext-unix-sk=11890815 -t 16528
</code>
For restore socketpair the server should create new pair and call criu restore asking it to [[Inheriting FDs on restore|inherit]] one. Example of command:
<code>
criu restore -d -D images -o restore.log --pidfile restore.pid -v4 -x --inherit-fd fd[3]:socket:[11890815]
</code>
test source code also available for this feature and can be found in criu source tree under test/socketpairs.
