      mnt: Carry run-time device ID in mount_info · 6217a84a
      Cyrill Gorcunov authored 
      When we're restoring fsnotify watchees we need to resolve
path to a handle at some mountpoint referred by @s_dev
member (device ID) which is saved inside image. This
ID actually may be changed at the every mount (say
one restores container after machine reboot) or in
case of container's migration.

Thus the test for overmounting in __open_mountpoint
will fail and we get an error.

Lets do a trick: introduce @s_dev_rt member which
is supposed to carry run-time device ID. When dumping
this member simply equal to traditional @s_dev fetched
from the procfs, but when restoring we fetch it from
stat call once mountpoint become alive.

https://jira.sw.ru/browse/PSBM-41610

v2:
 - predefine MOUNT_INVALID_DEV
 - use fetch_rt_stat instead of assigning device in restore_shared_options
 - copy @s_dev_rt in propagate_siblings and propagate_mount

      zdtm.py: The groups_test class for running groups · 0b0f40ec
      Pavel Emelyanov authored 
      So here's the new test class that handles the test from
groups set. The class is inherited from zdtm_test one as
what it does is -- starts the pseudo-init in ns/uns flavors
and asks one to spawn() the sub-tests from the list.

All groups tests can only be run inside ns flavor, so if
the host flavor is asked, just the pseudo-init is spawned.
This is because using ns flavor is the easiest way to spawn
all the sub tests under this init (however, h flavor can be
supported by marking the pseudo-init as sub-reaper).

On stop this pseudo-init is signalled to stop, it in turn
stops all the sub-tests and then exits. When the pid
namespace destruction is complete, the sub-tests .out-s are
checked.

      zdtm.py: Generator of groups of tests · 41296aaf
      Pavel Emelyanov authored 
      Introduce yet another tests set called 'groups'. Each test
in this set is a list of existing zdtm tests that can be
started side-by-side in an ns flavor.

To 'create' such a test the zdtm.py group action is used,
which lists tests and semi-randomly groups them together.
The grouping possibility is checked by comparing the .desc
files of those -- desc-s should coincide. One exception is
test dependencies, these are just merged together.

After running the group action there appears groups/ dir
with tests each containing just the list of zdtm tests
that are in a group. The respective .desc file is also
generated and this one matches the .desc for tests inside.

      zdtm.py: Prepare zdtm_test and flavors for mass test start · 23898bf1
      Pavel Emelyanov authored 
      This is -- add ability to pull more than one binary into
mntns root and ability to start zdtm test with more stuff
in the environment than generated in start method itself.

      zdtm: Remove unneeded re-exec · b9697482
      Pavel Emelyanov authored 
      When starting inside ns flavor the test_init() routine prepares
the binary to be run inside namespaces. In particular this routine
fork()-s an init, execve()-s one to pick up mappings and exe from
the new mntns and then fork()-s the test itself. In order to go
back to test_init() for test initialization the execve() is done
again, but it's actually not required and confuses the reader.

      zdtm: Introduce explicit prepare_namespaces() routine · 0ecd6c33
      Pavel Emelyanov authored 
      This one is to set up uids for userns, do ip l s lo up for netns
and do the prepare_mntns(). BTW, the latter's code is shifted one
tab left as this is where it should be.

      zdtm: Add socket_close_data01 test · 70b0e161
      Kirill Tkhai authored 
      This test is for unix sockets open in DGRAM mode.
Server opens a socket, binds it and waits for a signal.
Client connects to the socket and sends a message.

After the signal server checks that data is readable,
and that it's still possible to connect to the bound
socket.
