used as the basis for flow-based tunnelling. The
tun_key includes and replaces the tun_id in both struct

However, when the userspace code is updated to make use of the new
tun_key, the old behaviour will be deprecated and removed.

NOTE: With these changes, the tunneling code no longer assumes input and

reject port number 0.) intentionally prohibited using port 0, which is not
a valid OpenFlow port number, in OpenFlow commands and actions.  However,
since then we have discovered that the NVP controller uses port 0 in
"resubmit" actions and hence in flow matches as well.  This seems like a
valid enough use case; after all, the port number in a resubmit action is
really just an arbitrary number that need not (and preferably does not)
refer to an actual OpenFlow port.  Therefore, this commit restores the
ability to use port 0.

(Only functions that parse OpenFlow commands and actions from strings, not
those that interpret binary OpenFlow coming in on OpenFlow connections,

NOTE: This occurs intermittently depending on how ovsdb-server runs.
      Running ovsdb-client on a remote machine increases the possibility.

This is because ovsdb-server closes newly accepted tcp connection.
The following changesets caused it. struct jsonrpc_session::dscp isn't set
based on listening socket's dscp value.
- ovsdb-server creates passive connection and listens on it.
- ovsdb-server accepts connection by ovsdb_jsonrpc_server_run().
  The accepted socket inherits from the listening sockets.
  ovsdb_jsonrpc_server_run() creates json session, but leaves dscp of
  struct jsonrpc_session zero.
- On calling reconfigure_from_db(), it resets dscp value to
  all jsonrpc sessions. Eventually jsonrpc_session_set_dscp() is called.
  Then jsonrpc_session_force_reconnect() closes the connection.

With this patch,
- struct jsonrpc_session::dscp is correctly set based on
  listening sockets dscp value.
- dscp of listening socket is changed dynamically by setsockopt.
  This leaves a window where accepted socket may have old dscp.

of OpenFlow 1.1+ actions, so the two sets of actions have to be

ovsdb-server: Fix null pointer deref when bool "is_connected" is empty.

The ovsdb-server supports obtaining its remote connection targets from a
database table and updating that table with connection status information.
One of the supported connection status columns is a boolean column named
"is_connected".  The code in ovsdb-server blindly assigned a bool into
this column without checking that it actually had space allocated for one.
This was and is fine with the ovs-vswitchd schema, which always has exactly
one value in this column.  However, if a database schema makes this column
optional, and there are actually no values in it, then this assignment
dereferences a null pointer.

This commit fixes the problem by allocating space for a bool if none has
yet been allocated.

Noticed while adding an extra test for the connection status feature.

0xffffffff and allows the OF1.0 range to be used for ordinary ("physical")
switch ports.  This means that, naively, the meaning of a port number in
the range 0xfff8 to 0xffff given on the ovs-ofctl command line depends on
the protocol in use.  This commit implements something a little smarter:

    - Accept keyword names (e.g. LOCAL) for special reserved ports

      were only accepted in some places).

    - Translate 0xfff8...0xffff to 0xfffffff8...0xffffffff for now, since
      OF1.1+ isn't in widespread use and those particular ports aren't
      likely to be in use in OF1.1+ anyway.

    - Log warnings about those ports when they are specified by number, to
      allow users to fix their invocations.

Also:

    - Accept the OF1.1+ port numbers for these ports, without warning, for
      compatibility with the upcoming OF1.1+ support.

    - Stop accepting port number 0, which has never been a valid port
      number in OpenFlow 1.0 and later.  (This required fixing some tests
