Setting importance to low, as far as I could tell there is no impact apart from a scary TRACE error in the log.

Ignore exception when deleting linux bridge if doesn't exist

    Linux bridge is not handling RuntimeError exception when it is trying
    to delete network's bridge, which is deleted in parallel by nova.
    Fullstack test has similar scenario, it creates network's bridge for
    agent and deletes the bridge after the test, like nova.

Linux bridge agent has to ignore RuntimeError exception if the bridge
doesn't exist.

Clear DVR MAC on last agent deletion from host

    Once all agents are deleted from a host, the DVR MAC generated
    for that host should be deleted as well to prevent a buildup of

Add an option for WSGI pool size

    this can cause requests to wait within one process
    for available database connection while other processes
    remain available.

    By adding a wsgi_default_pool_size option functionally
    identical to that of Nova, we can lower the number of
    greenlets per process to be more in line with a typical

    after the initial flows are set back up.

Fix deprecation warning for external_network_bridge
    
    We only want this to warn when a deployer has set anything other
    than a blank string. The olso cfg would warn whenever it was set
    so it was incorrectly warning on the value we want operators to
    set it to.
    
    This changes the cfg option to not use deprecated for removal and
    the L3 agent config validation to emit a warning if its not set
    to the value we are suggesting.

Add ALLOCATING state to routers
    
    This patch adds a new ALLOCATING status to routers
    to indicate that the routers are still being built on the
    Neutron server. Any routers in this state are excluded in
    router retrievals by the L3 agent since they are not yet
    ready to be wired up.
    
    This is necessary when a router is made up of several
    distinct Neutron resources that cannot all be put
    into a single transaction. This patch applies this new
    state to HA routers while their internal HA ports and
    networks are being created/deleted so the L3 HA agent
    will never retrieve a partially formed HA router. It's
    important to note that the ALLOCATING status carries over
    until after the scheduling is done, which ensures that
    routers that weren't fully scheduled will not be sent to
    the agents.
    
    An HA router is placed in this state only when it is being
    created or converted to/from the HA state since this is
    disruptive to the dataplane.
    
    This patch also reverts the changes introduced in
    Iadb5a69d4cbc2515fb112867c525676cadea002b since they will
    be handled by the ALLOCATING logic instead.

Cleanup stale OVS flows for physical bridges
    
    Perform deletion of the stale flows in physical bridges consistently with
    br-int and br-tun, respecting drop_flows_on_start configuration option.
    Added tests for auxiliary bridge and functional tests for the physical
    bridge using VLAN/flat external network. Fixes part of the bug 1514056;
    together with [1] and [2], the bug should be considered fixed.
    
    The commit also fixes inconsistency between netmask of allocated IP
    addresses assigned in _create_test_port_dict and ip_len in _plug_ports
    of base.py.

Notify resource_versions from agents only when needed
    
    resource_versions were included into agent state reports recently to
    support rolling upgrades (commit 97a272a892fcf488949eeec4959156618caccae8)
    The downside is that it brought additional processing when handling state
    reports on server side: update of local resources versions cache and
    more seriously rpc casts to all other servers to do the same.
    All this led to a visible performance degradation at scale with hundreds
    of agents constantly sending reports. Under load (rally test) agents
    may start "blinking" which makes cluster very unstable.
    
    In fact there is no need to send and update resource_versions in each state
    report. I see two cases when it should be done:
     1) agent was restarted (after it was upgraded);
     2) agent revived - which means that server was not receiving or being able
        to process state reports for some time (agent_down_time). During that
        time agent might be upgraded and restarted.
    
    So this patch makes agents include resource_versions info only on startup.
    After agent revival server itself will update version_manager with
    resource_versions taken from agent DB record - this is to avoid
    version_manager being outdated.

ADDRESS_SCOPE_MARK_IDS should not be global for L3 agent
    
    Otherwise agent becomes unable to handle more than 1024 routers
    (including deleted routers) and starts failing.
    
    It should be enough to distinguish address scopes inside router namespace,
    so this patch moves ADDRESS_SCOPE_MARK_IDS set to the RouterInfo class.

    Commit 9ec466cd42de94c2fad091edfd7583a5f47eb87a was not enough
    since it checked l3 agents in the same transaction that was used
    to fetch down bindings - so agents always were down even if actually
    they went back online.

    we use new transaction and fetch up-to-date info for the agent.

firewall: don't warn about a driver that does not accept bridge
    
    Drivers that do not need the bridge parameter are safe to ignore it.
    Actually, the base abstract interface for those drivers does not allow
    to pass the new parameter.
    
    Ideally, the base class __init__ signature would change to accept the
    argument, but we can't do it without breaking API.
    
    So instead, just handle both types of drivers - those that accept the
    additional argument, and those that don't. And don't assume the latter
    are somehow wrong.

Iptables firewall prevent IP spoofed DHCP requests
    
    The DHCP rules in the fixed iptables firewall rules were too permissive.
    They permitted any UDP traffic with a source port of 68 and destination
    port of 67. Care must be taken since these rules return before the IP
    spoofing prevention rules. This patch splits the fixed DHCP rules into
    two, one for the discovery and request messages which take place before
    the instance has bound an IP address and a second to permit DHCP
    renewals.

Fix race conditions in IP availability API tests
    
    DHCP port creation is asynchronous with subnet creation.
    Therefore there is a time window where, depending on how fast
    the DHCP agent honors the request, the DHCP port IP allocation
    may or may not be accounted for in the total number of used IP
    for the network. To kill the race, do not run dhcp on the
    created subnets at all.

Fix zuul_cloner errors during tox job setup
    
    Since [1], Tempest is a pip installable package, and that prevents zuul_cloner
    to work correctly. This change moves away from the existing logic in tox_install,
    and adds tempest as an explicit requirement for the api job. This is in fact
    the only tox target that needs Tempest to work.
    
    tox_install.sh has become less important now, but cleanup is left as follow
    up, to speed up gate salvation.

Add IPAllocation object to session info to stop GC
    
    This adds the IPAllocation object created in the _store_ip_allocation
    method to the session info dictionary to prevent it from being
    immediately garbage collected. This is necessary because otherwise a
    new persistent object will be created when the fixed_ips relationship
    is referenced during the rest of the port create/update opertions.
    This persistent object will then interfere with a retry operation
    that uses the same session if it tries to create a conflicting record.
    
    By preventing the object from being garbage collected, the reference
    to fixed IPs will re-use the newly created sqlalchemy object instead
    which will properly be cleaned up on a rollback.
    
    This also removes the 'passive_delete' option from the fixed_ips
    relationship on ports because IPAllocation objects would now be
    left in the session after port deletes. At first glance, this might
    look like a performance penalty because fixed_ips would be looked
    up before port deletes; however, we already do that in the IPAM
    code as well as the ML2 code so this relationship is already being
    loaded on the delete_port operation.

DVR: Increase the link-local address pair range
    
    The current dvr_fip_ns.py file has FIP_LL_SUBNET configured
    with a subnet prefixlen of /23 which only allows 255 pairs of
    link-local addresses to be generated. If the number of routers
    per-node increases beyond the 255 limit it raises an assertion.
    
    This patch increases the link-local address cidr to be a /18
    to allow for 8K routers. The new range was chosen to not
    overlap with the original, allowing for in-place upgrades
    without affecting existing routers.

SG protocol validation to allow numbers or names
    
    SG rule protocol provided is validated against the DB rules'
    protocols for both number and name. The filter provided to DB
    is modified so that it is queried for records with both the
    protocol name and number, instead of exactly the type provided
    with the input. The returned DB rule record's protocol field is
    validated against the supplied SG protocol field for both name
    or number.
    This way, user is still allowed to enter protocol name or number
    to create a rule, and API compatibility is maintained.

port security: gracefully handle resources with no bindings
    
    Resources could be created before the extension was enabled in the
    setup. In that case, no bindings are created for them. In that case, we
    should gracefully return default (True) value when extracting the value
    using the mixin; and we should also create binding model on update
    request, if there is no existing binding model for the resource.
    
    While at it, introduced a constant to store the default value for port
    security (True) and changed several tests to use the constant instead of
    extracting it from extension resource map.

Ignore exception when deleting linux bridge if doesn't exist
    
    Linux bridge is not handling RuntimeError exception when it is trying
    to delete network's bridge, which is deleted in parallel by nova.
    Fullstack test has similar scenario, it creates network's bridge for
    agent and deletes the bridge after the test, like nova.
    
    Linux bridge agent has to ignore RuntimeError exception if the bridge
    doesn't exist.

Don't delete br-int to br-tun patch on startup
    
    When starting up, we don't want to delete the patch port between br-int
    and br-tun unless we're also dropping the flows..  In liberty both of
    these bridges were switched to not dump flows on startup and to put the
    bridges in secure mode so that default flood flows are not installed
    when the bridge is created.
    
    Without this patch the patch port is torn down and not reinstalled until
    br-tun is setup again.

ovs-fw: Mark conntrack entries invalid if no rule is matched
    
    This patch makes sure that existing connection breaks once security
    group rule that allowed such connection is removed. Due to correctly
    track connections on the same hypervisor, zones were changed from
    per-port to per-network (based on port's vlan tag). This information is
    now stored in register 6. Also there was added a test for RELATED
    connections to avoid marking such connection as invalid by REPLY rules.

Close XenAPI sessions in neutron-rootwrap-xen-dom0
    
    Neutron with XenServer properly doesn't close XenAPI sessions.
    If it creates these sessions so rapidly, the XenServer host eventually
    exceeds its maximum allowed number of connections.
    This patch adds a close process for session.

Watch for 'new' events in ovsdb monitor for ofport
    
    This adjusts the event handling logic in the ovs interface
    monitor to watch for 'new' events as well because this is
    when ofports are assigned to the interface. Previously we
    were only watching for 'insert' events, which would never
    include the ofport so this led to every port being skipped
    initially by the OVS agent and then picked up on the next
    polling interval.

Removes host file contents from DHCP agent logs
    
    The change I3ad7864eeb2f959549ed356a1e34fa18804395cc addressed a
    performance impact by removing logging calls from inside the loop that
    creates the hosts file in memory. However, it also introduced the
    dumping of said hosts file to the logs.
    
    On deployments with a very high number of ports(>5K), this increases the
    load of the node substantially. The problem is worse when a high number
    of port updates is received in a short amount of time.
    
    There is also the administrative burden caused by the sheer amount of
    data being logged.
    
    If the content of the host file is required for debugging purposes, it
    can be found at /opt/stack/data/neutron/dhcp/<net-id>/host
    
    This patch is trivial and only removes the logging of the file contents.
    The 'building'/'done building' logging calls may still provide useful
    information.
