Bug Description

If one or more interfaces in physical_interface_mappings does not exist for whatever reason, the Linux bridge agent fails badly rather than providing a useful error message.

I looked at making the code between the agents common for this, but it is different enough that it's not very feasible (OVS looks up bridges from OVSDB).

Neutron-Ironic integration patch

    This patch is in preparation for the integration
    of Ironic and Neutron. A new vnic_type is being
    added so that ML2 drivers can filter for all
    Ironic ports based upon match for 'baremetal'.
    Nova/Ironic will set this vnic_type when issuing
    port-create request to neutron.
    (e.g. binding:vnic_type = 'baremetal' )

DVR: fix router scheduling

    Fix scheduling of DVR routers to not stop scheduling once
    csnat portion was scheduled. See bug report for failing
    scenario.

    This partially reverts

Do not delete fip namespace during l3 dvr agent resync
    
    This was introduced by commit 46608806aa7a9c60214e28429ca5a8b87b2a15de
    which didn't take into account that fip namespace name is composed
    from external network id rather than router id.
    The fix is to ensure fip namespaces for the known routers are kept
    by namespace manager on agent resync.

Validate updated allocation pool before using it
    
    The allocation pool specified during subnet-update is being
    used in gateway validation checks before the allocation pool
    is ever validated.  Errors indicating that the gateway IP is
    invalid are returned when it is the allocation pool that is
    actually in error.
    
    Additional testing of the allocation pool is also being added
    to the subnet-update unit tests.

Remove quotes from subshell call in tools/split.sh
    
    Always no quotes for $() statement.
    
    We don't need quotes to hold blanks in result:
     # i=$(echo 1 2 3)
     # echo $i
     1 2 3
     #
    
    These quotes can make something wrong in some case:

    The extension driver is intercepted by driver manager currently. It will

    process will continue even if preceding extension driver get a wrong/useless

Broadcast service port's arp in DVR
    
    When creating VMs, DVR router will broadcast VM's arp details to all the
    l3 agents hosting it. that enable dvr can forwarding networking traffic
    in link layer, but when the port is attached to the service liking
    lbaas, their arp will not be broadcast, so the dvr do not know its mac,
    and will cause that vms in other subnet can not reach the service port
    through the dvr router.

Initialize ancillary_port_info dict as blank in OVS agent
    
    The first assignment of ancillary_port_info was from the scan_ancillary_ports
    function which could result in an exception and result in ancillary_port_info
    being unbound for the port stats scan below.
    
    This patch just initializes ancillary_port_info as an empty dict so the port

Enable fullstack multinode tests, add L3 HA test exemplar
    
    * Created a 'resources' subdir and moved all fixture files
      to it.
    * Split ML2ConfigFixture to the server-side ml2 configuration
      fixture, and the OVS agent configuration fixture.
    * Neutron process logs were using H:M:S format as their file name,
      but when starting multiple agents of the same type my machine
      was fast enough to do that in the same second so that different
      processes were outputting to the same log file. No good!
      Added ms to the log name format. I also changed the log time
      from UTC to local timezone.
    * Renamed and moved 'FullstackFixture' to neutron/tests/fullstack/
      resources/environment.Environment
    * Added a 'Host' abstraction that groups agents that report with
      the same 'host' value. Hosts may be interconnected by the
      environment via shared bridges.
    * The 'Environment' class will accept global

      a  list of host attributes (Configuration that may differ between
      hosts like the l3 agent mode [legacy, dvr, dvr_snat]).
    * Made OVS agent and L3 agent fixtures expose their bridges
      so that I could interconnect them.
    * Added a super simple L3 HA test to show that this entire thing
      works.

DB, IPAM & RPC changes for IPv6 Prefix Delegation
    
    This patch includes the DB, IPAM & RPC changes needed for the IPv6 Prefix
    Delegation feature.
    
    To enable this feature, the subnetpool_id attribute of subnets has been
    modified to allow for a special subnetpool identifier - "prefix_delegation".
    
    WORKFLOW:
    
    1. Admin sets default_ipv6_subnet_pool in neutron.conf to "prefix_delegation"
    2. User creates a new IPv6 subnet without a CIDR or subnetpool ID
    3. User creates an interface between this subnet and a router with an existing
    external interface
    
    The agent-side changes will follow in separate patches.
    
    A documentation patch is up for review here:
    
    https://review.openstack.org/#/c/178739
    
    Video guides for configuring and using this feature are available on
    YouTube:

Add oslo db retry decorator to the RPC handlers
    
    The decorator was previously added at the API layer
    (commit 4e77442d529d9803ff90de905b846af940eaf382,
    commit d04335c448aa15cf9e1902e22ed4cd17b6ed344b).
    However some RPC handlers are also dealing with port
    create/update/delete operations, like dhcp ports for example.
    We need to cover these cases too.
    
    Also remove db retry from ml2 plugin delete_port()
    as it's not needed once we retry at the API and RPC layers.
    (there is already a unit test on this)
    
    The patch also adds a unit test for checking deadlock
    handling during port creation at API layer.
    Though it's not directly related to the current fix,
    I decided to leave it for regression preventing purposes.

Move 1c844d1677f7 expand migration to appropriate branch
    
    Commit cb60d0bb4e0cc0cba68f59fdf5f4e89d6ec52950 added an expand
    migration. Howewer it indicated a contract migration as its
    ancestor (2a16083502f3). As a result the migration was treated
    by alembic as a contract one, even if it was defined in the
    'expand' directory.
    
    This patch 'rebases' this migration on top of the expand branch
    HEAD. This might impact trunk chasers which have already executed
    migration 1c844d1677f7 as a part of the contract branch.

Introduce get_ports_attributes in OVSBridge
    
    OVSBridge was inheriting db_list from BaseOVS, which was
    returning the information of all the ports on the machine,
    not only the ones belonging to the bridge.
    The OVSNeutronAgent was using that method with the assumption
    that ports were filtered by bridge.
    To avoid confusion, this patch add a new method to OVSBridge
    get_ports_attributes to query the info for all the ports
    belonging to the bridge.
    db_list is removed from BaseOVS since that method is already
    available in ovsdb/api.py
    ovs_lib methods that use db_list are refactored accordingly.

Ensure non-overlapping cidrs in subnetpools with galera
    
    This change enables galera support in _lock_subnetpool[1]. It uses an
    update to disallow 2 transactions performing concurrent subnet
    allocation in the same subnetpool to succeed: the 2 transactions will
    conflict because they update the same row so the db (including Galera
    multi-writer cluster) will discard the last transaction and
    Controller.create[2] will catch and retry the "discarded" allocation.
    
    This change adds the "hash" attribute in "subnetpools" table to enable
    previous update.

Prevent update alloc pool over existing gateway ip
    
    The gateway IP for a subnet is not allowed to be listed in the
    allocation pool for that subnet. This restriction is checked and
    enforced at subnet-create time.
    
    During subnet-update, it is only partially checked. An
    exception is returned if the update request tries to place the gateway
    IP in an existing allocation pool OR if both gateway and allocation
    pool are being changed and the gateway is located in the new pool.
    
    If only the allocation pool is being updated, no check is made to
    verify that the new allocation pool does not contain the existing
    gateway IP.

Extend vxlan_group option to allow a range of group addresses
    
    If vxlan_group is specified in CIDR notation, it is interpreted as a
    range of group addresses. VXLAN VNIs are mapped to group addresses in
    a many-to-one round robin fashion, or one-to-one if a large enough
    range is provided. Since VNIs are 24 bits, a /8 such as 239.0.0.0/8
    allows each VNI to use a unique multicast group. (239.0.0.0/8 also
    happens to be the "site-local" multicast range.)
    
    With multiple VNIs on a single multicast group, it is likely that
    VTEPs will unnecessarily receive broadcast/unknown/multicast
    datagrams for VNIs in which they do not participate. Using a range of
    groups mitigates or eliminates this issue. It is thus an alternative
    to the l2_population extension and driver for environments where both
    multicast and linuxbridge are used.
    
    The default setting is unchanged, but the comments in the ini file
    suggest 239.0.0.0/8 as an alternative. Administrators are free to use
    any valid multicast range that can be expressed in CIDR notation, and
    should choose a size and starting address that make sense for their
    environment.

Update port bindings for master router
    
    An HA port needs to point to the correct host (where the master router
    is running) in order for L2Population to work.
    
    Hence, this patch introduces two fixes:
    * When a port owned by an HA router is up we make sure it points to the
      right node where the master is running, or a random node if there is
      no master yet (This corner case is fixed by the 2nd bullet point).
    
    * When a L3 agent reports it's hosting a master, we need to update the
      port binding to the host the master is now running on. This fixes
      both routers with no elected master (Yet) and failovers.
    
    This patch also changes the L3 HA failover test to use l2pop.
    Note that the test does not pass when using l2pop without this patch.

Update dhcp host portbinding on failover
    
    When a dhcp server is moved to new host on failover,
    tunnel is not created.
    
    When a dhcp server is moved to new host,
    1) network-hostagent binding is updated(properly i.e with new host).
    2) dhcp port-hostagent binding is not updated
       ( dhcp port is still bound to old host)
    If dhcp port-bound agent is different from the new dhcp agent
    (which is now taking care of this dhcp port), neutron plugin won't
     notify the l2pop, and hence tunnel is not created.
    
    As after failover, the new agent is taking care of this dhcp port,
    update portbinding with the new host. This will allow neutron plugin
    to notify l2pop(which will create tunnel).

Make '_create_router' function handle Boolean kwargs correctly
    
    The function allows arbitrary kw arguments to be specificed.
    Those kw arguments whose key is specified in the function
    parameter 'arg_list' are then passed in the create router REST
    API call.
    
    The code line that checks if a kw argument key is included in
    'arg_list' does not work with Boolean kw arguments. Nor does it
    work with None kw argument values. This is a limitation as
    tests in inheriting classes may need such kw arguments.
    
    This patch fixes the faulty 'if' clause so that it simply
    checks that the kw argument key is in 'arg_list'. This makes it
    support Boolean kw arguments and kw arguments with value None.
