dd9b11acbc ctdb-protocol: Add missing push support for new controls
CTDB_CONTROL_TCP_CLIENT_DISCONNECTED and
CTDB_CONTROL_TCP_CLIENT_PASSED were added in commits
c6602b686b and
037e8e449d.  They were missing test
support for the packet push/pull.  While adding the testing (for
completeness, before adding another new control) I noticed that the
push functionality was absent.  This adds that, along with the test
support.

037e8e449d ctdb: add/implement CTDB_CONTROL_TCP_CLIENT_PASSED
With multichannel a tcp connection is registered first with
a temporary smbd process, that calls CTDB_CONTROL_TCP_CLIENT
first and then passes the tcp connection to the longterm smbd
that already handles all connections belonging to the specific
client_guid. That smbd process calls CTDB_CONTROL_TCP_CLIENT
again, but the 'tickle' information is already there.
When the temporary smbd process exists/disconnects from ctdb
or calls CTDB_CONTROL_TCP_CLIENT_DISCONNECTED, the 'tickle'
information is removed, while the longterm smbd process
still serves the tcp connection.

0d8084ed62 ctdb-protocol: CID 1499395: Uninitialized variables (UNINIT)
Issue is reported here:

853     	case CTDB_CONTROL_DB_VACUUM: {
854     		struct ctdb_db_vacuum db_vacuum;
855
>>>     CID 1499395:  Uninitialized variables  (UNINIT)
>>>     Using uninitialized value "db_vacuum.full_vacuum_run" when calling "ctdb_db_vacuum_len".
856     		CHECK_CONTROL_DATA_SIZE(ctdb_db_vacuum_len(&db_vacuum));
857     		return ctdb_control_db_vacuum(ctdb, c, indata, async_reply);
858     	}

The problem is that ctdb_bool_len() unnecessarily dereferences its
argument, which in this case is &db_vacuum.full_vacuum_run.  Not a
security issue because the value copied by dereferencing is not used.

RFC5952 says the existing style is not recommended and the [] style

There are more optimised ways of adding the square brackets but they
tend to be uglier.

Parsing IPv6 sockets without [] is now tested indirectly by parsing

49dc5d8cd2 ctdb-protocol: Add new controls to disable and enable nodes
These are CTDB_CONTROL_DISABLE_NODE and CTDB_CONTROL_ENABLE_NODE.

For consistency these match CTDB_CONTROL_STOP_NODE and
CTDB_CONTROL_CONTINUE_NODE.  It would be possible to add a single
control but it would need to take data.

The aim is to finally fix races in flag handling.  Previous fixes have
improved the situation but they have only narrowed the race window.
The problem is that the recovery daemon on the master node pushes
flags to nodes the same way that disable and enable are implemented.
So the following sequence is still racy:

1. Node A is disabled
2. Recovery master pulls flags from all nodes including A
3. Node A is enabled
4. Recovery master notices A is disabled and pushes a flag update to
   all nodes including node A
5. Node A is erroneously marked disabled

Node A can not tell if the MODIFY_FLAGS control is from a "ctdb
disable" command or a flag update from the recovery master.

The solution is to use a different mechanism for disable/enable and
for a node to ignore MODIFY_FLAGS controls for their own flags.
