Bug Description

if L2 agent uses enhanced-security-group-rpc, in bellow case there will be a KeyError in neutron server:
1. Create security group with IPv6 ingress rule but no IPv4 ingress rule.
(or delete IPv4 ingress rule from default security group)
2. Launch a VM on an IPv4 subnet, making it member of sec group created earlier

Instance will not get its network info. Neutron server starts reporting following errors and sends them to agent on each request for devices info:

I was unable to reproduce this on devstack. After creating a port with IPv4 address in default security group and then deleting default IPv6 ingress rule from default security group I don't see any traces in q-svc. Can you please add more details on how to reproduce?

hi Oleg Bondarev, the port should be used by a VM, you can try it again:
1. create a port with 'IPv4' address in default security group
2. create a VM using this port
3. delete the default rule 'IPv6' ingress

I am so sorry for this bug, if you can reproduce, please help me to change 'Importance' to high, that can make other reviewer pay close attention to

the '_select_ips_for_remote_group' will select both IPv4 and IPv6 address in given remote security group id, if there is a port with IPv4 address in remote security group but no IPv4 rule,
sg_info['sg_member_ips'][sg_id][ethertype] will happen KeyError

Big Switch: Switch to TLSv1 in server manager

    Switch to TLSv1 for the connections to the backend
    controllers. The default SSLv3 is no longer considered
    secure.

    TLSv1 was chosen over .1 or .2 because the .1 and .2 weren't
    added until python 2.7.9 so TLSv1 is the only compatible option
    for py26.

Move disabling of metadata and ipv6_ra to _destroy_router_namespace

    I noticed that disable_ipv6_ra is called from the wrong place and that
    in some cases it was called with a bogus router_id because the code
    made an incorrect assumption about the context. In other case, it was
    never called because _destroy_router_namespace was being called
    directly. This patch moves the disabling of metadata and ipv6_ra in
    to _destroy_router_namespace to ensure they get called correctly and
    avoid duplication.

Moves the HA resource creations outside of transaction
    
    Currently the HA resources are created in the
    _create_router_db which includes calls to
    the plugin and generates RPC calls. Even if the
    resource creations are outside of any transaction
    from the _create_router_db point of view, this
    method is  called in a transaction from the
    create_router method.
    This patch moves the resource creations to the
    create_router method outside the transaction.
    The failures are handled as previously with
    a try/expect.

Remove superfluous except/re-raise
    
    This exception code catches all exceptions, and then always raises them
    again.
    
    More interestingly, it uses excutils.save_and_reraise_exception
    incorrectly (outside a `with` statement), which triggers the pylint test
    designed to catch exactly this.

Schema enhancement to support MultiSegment Network
    
    Description:
    Currently, there is nothing in the schema that ensures segments
    for a network are returned in the same order they were specified
    when the network was created, or even in a deterministic order.
    
    Solution:
    We need to add another field named 'segment_index' in
    'ml2_network_segment' table containing a numeric position index.
    With segment_index field we can retrieve the segments in the
    order in which user created.
    
    This patch set also fixes ML2 invalid unit test case in
    test_create_network_multiprovider().

Remove redundant initialization and check from DVR RPC mixin
    
    The initialization, as well as the recurrent checks on whether the agent
    is able to handle DVR requests, are not necessary; this is because the
    dvr_agent is going to be set at the time the L2 agent starts receiving
    RPC messages.

Improve performance of security group DB query
    
    The _select_ips_for_remote_group method was joining the
    IP allocation, port, allowed address pair, and security group tables
    together in a single query. Additionally, it was loading all of
    the port columns and using none of them. This resulted in a
    very expensive query with no benefit.
    
    This patch eliminates the unnecessary use of the port table by joining
    the IP allocation table directly to the security groups and allowed
    address pairs tables. In local testing of the method, this sped it up
    by an order of magnitude.

Fix KeyError in dhcp_rpc when plugin.port_update raise exception
    
    KeyError exception is seen because of following reasons
    
    * DhcpRpcCallback._port_action() is called by two functions
       -  DhcpRpcCallback.create_dchp_port()
       -  DhcpRpcCallback.update_dhcp_port()
    
    * When create_dhcp_port() function calls _port_action(), the
      function argument 'port' will have the body as
      {'port': {'network_id': foo_network_id, 'fixed_ips': [..] ...}
    
    * When update_dhcp_port() function calls _port_action(), the
      function argument 'port' will have the body as
      {'id': port_id, 'port': {{'port': {'network_id': foo_network_id,
    			            'fixed_ips': [..] ...}}
    
    * If an exception occurs when _port_action() calls plugin.create_port(),
      network id is accessed as
      net_id = port['port']['network_id']
    
    * If an exception occurs when _port_action() calls plugin.update_port(),
      network id is accessed as
      net_id = port['port']['network_id']
      which is causing the KeyError. network_id should have been accessed as
      net_id = port['port']['port']['network_id']
    
    This patch fixes the issue by making the _port_action() take the
    same port body. update_dhcp_port() insteading of passing the port_id
    and port information in a single argument, it now adds port_id
    in the port body itself.

Call DVR VMARP notify outside of transaction
    
    The dvr vmarp table update notification was being called inside
    of the delete_port transaction in ML2, which can cause a yield
    and lead to the glorious mysql/eventlet deadlock.
    
    This patch moves it outside the transaction and adjusts it to
    use an existing port dictionary rather than re-looking it up since
    the port is now gone from the DB by the time it is called.

Race for l2pop when ports go up/down on same host
    
    With l2pop enabled, race exists in delete_port_postcommit
    when both create/update_port and delete_port deal with
    different ports on the same host, where such ports are
    either the first (or) last on same network for that host.
    This race happens outside the DB locking zones in
    the respective methods of ML2 plugin.
    
    To fix this, we have moved determination of
    fdb_entries back to delete_port_postcommit and removed
    delete_port_precommit altogether from l2pop mechanism
    driver.  In order to accomodate dvr interfaces, we
    are storing and re-using the mechanism-driver context
    which hold dvr-port-binding information while
    invoking delete_port_postcommit.  We loop through
    dvr interface bindings invoking delete_port_postcommit
    similar to delete_port_precommit.

Use EUI64 for IPv6 SLAAC when subnet is specified
    
    This commit uses EUI64 for SLAAC and stateless IPv6 address
    when subnet id in fixed_ip is specified.
    
    After this patch, all the ports created on a subnet which has
    ipv6_address_mod=slaac or ipv6_address_mod=dhcpv6-stateless
    will use EUI64 as the address.
    This patch also checks if fixed IP address is specified
    for a IPv6 subnet with address mode slaac or dhcpv6-stateless
    during creating or updating a port. If yes, raise InvalidInput
    error to stop the port creation or update.

    fixed_ip should not be specified for a slaac subnet.

Reduce security group db calls to neutron server
    
    Within ovs agent daemon loop, prepare_devices_filter will impose heavy workloads
    to neutron server in order to retrieve the security groups message to apply
    firewall rules. If agent is configured to use Noopfirewall driver or security
    groups are disabled, there is no need for loading the rules from server and
    refreshing the firewalls. This will reduce the number of db calls and improve
    performance for neutron server in this case.

NSX: drop support to deprecated dist-router extension
    
    The NSX plugin originally implemented its own 'dist-router' extension.
    During the Juno timeframe the DVR extension was introduced and the NSX
    plugin was ported to support both. At the same time 'dist-router' was
    marked for removal in Kilo.
    
    Now that Kilo opened, we can drop the deprecated one.

Refactor _process_routers to handle a single router
    
    The method _process_routers no longer handles multiple routers.  The
    only caller of this method would construct a list of exactly one
    router in order to make the call.  This made the for loop unnecessary.
    The method's logic is too heavy for its current purpose.  This commit
    removes much of the weight.
    
    The use of the sets in this method is also no longer necessary.  It
    became clear that all of it boiled down to "if the router is not
    compatible with with this agent but it is known in router_info from
    before then we need to remove it."  This is an exceptional condition
    that shouldn't be handled in this method so I raise an exception and
    handle it in process_router_update where other router removal is
    handled.  Logging was added for this exceptional condition.
    
    The eventlet pool was also obsolete.  It was used to spawn two methods
    and there was a waitall at the end.  The other refactoring made it
    clear that the two spawns were mutually exclusive.  There was only one
    thread spawned for any given invocation of the method and the eventlet
    pool is overkill.

Disable PUT for IPv6 subnet attributes
    
    In Juno we are not ready for allowing the IPv6 attributes on a subnet
    to be updated after the subnet is created, because:
    - The implementation for supporting updates is incomplete.
    - Perceived lack of usefulness, no good use cases known yet.
    - Allowing updates causes more complexity in the code.
    - Have not tested that radvd, dhcp, etc. behave OK after update.
    
    Therefore, for now, we set 'allow_put' to False for the two IPv6
    attributes, ipv6_ra_mode and ipv6_address_mode. This prevents the
    modes from being updated via the PUT:subnets API.

Big Switch: Don't clear hash before sync
    
    This patch removes the step of clearing the consistency
    hash from the DB before a topology sync. This will ensure
    that inconsistency will be detected if the topology sync
    fails.
    
    This logic was originally there to make sure the hash header
    was not present on the topology sync call to the backend.
    However, the hash header is ignored by the backend in a sync
    call so it wasn't necessary.

L3 Agent should generate ns_name in a single place

    unification of this creation code with a property which lives in

L3 agent should always use a unique CONF object
    
    The l3 agent accepts an oslo configuration in its constructor and uses
    it throughout the code, but there are some references to the global
    configuration object held by the oslo library. Since HA functional
    tests need to create two agents, the configuration should be consistent
    throughout the code.
    
    The important difference between the agents is their 'host' value so
    that they create different namespaces, and 'state_path' value so the
    agents get their own filesystem root.

Iterate over same port_id if more than one exists
    
    In certain cases where multiple ports can have the same
    external_ids:iface_id property, the ovs agent will arbitrarily choose
    one and ignore the rest. In case the chosen port isn't on the
    integration bridge the ovs agent is managing, an error is returned to
    the calling function. This is faulty since one of the other ports may
    belong to the correct bridge and it should be chosen instead.
    
    This is interesting for future L3 HA integration tests, where 2
    different instances of l3 agents are needed to run on the same machine.
    In this case, both agents will register ports which have the same
    iface_id property, but obviously only one of the ports is relevant for
    each agent.

Don't fail when trying to unbind a router
    
    If a router is already unbound from an l3 agent, don't fail.  Log
    the condition and go on.  This is harmless since it can happen
    due to a delete race condition between multiple neutron-server
    processes.  One delete request can determine that it needs to
    unbind the router.  A second process may also determine that it
    needs to unbind the router.  The exception thrown will result
    in a port delete failure and cause nova to mark a deleted instance
    as ERROR.

remove linuxbridge plugin
    
    This changeset removes the linuxbridge plugin, but retains the agent for ML2.
    The database models were not removed since operators will need to migrate the
    data.
    
    Additionally, the ml2 migration script was altered to support Juno.  For
    testing, a user must either run the migration against the icehouse
    scheme or run the update, manually change alembic_version to juno and
    then run the migration script.  Once the juno migration is added, this
    manually step will not be required.

Add admin tenant name to nova notifier
    
    This change introduces the ability to use the nova admin
    tenant name with the nova notifier in place of the nova
    admin tenant id which may not be available when the neutron
    service is being configured as is the case with tripleo
    installations where the neutron service is configured and
    started before the nova admin tenant has been configured in
    keystone and thus does not have a known id.
    
    DocImpact
    Introduces the nova_admin_tenant_name configuration entry as
    an optional configurable value in neutron.conf.  If the
    nova_admin_tenant_name is configured and the nova_admin_tenanat_id
    is not configured, a performance impact may be seen because
    keystone will become involved in communication between neutron
    and nova.

ML2: move L3 cleanup out of network transaction
    
    Move _process_l3_delete out of the delete_network
    transaction to eliminate the semaphore deadlock that
    occurs when it tries to delete the ports associated
    with existing floating IPs.
    
    It makes more sense to live outside of the transaction
    anyway because the operations it performs cannot be
    rolled back only in the database if the L3 plugin makes
    external calls for floating IP creation/deletion.
    e.g. if delete_floatingip is successful, it may have
    deleted external resources and restoring the DB records
    would make things inconsistent.
    
    If a failure to delete the network does occur, any cleanup
    done by _process_l3_delete will not be reversed.

    A regular user can reset an admin-only attribute to its default

    Now, in the case of update, the function should not pay attention

    port. That is, there may be a race for the creation of the default
    security group for the tenant.
    The problem was introduced by commit acf44dba26ca8dca47bfb5fb2916807f9f4e2060

Stop admin using other tenants unshared rules
    
    If the firewall rules are not shared and if they belong to different
    tenants, then admin should not be able to create a policy using
    these rules and he should not be able to insert such rules into
    policies. An exception should be raised in such case. Added new
    exception “FirewallRuleConflict” to handle such conditions.

Eliminate OrderedDict from test_api_v2.py
    
    Neutron cannot possibly be passing tests under Python 2.6, as
    neutron/tests/unit/test_api_v2.py is referencing
    collections.OrderedDict, which does not exist in Python 2.6.
    Since there is no reason to use an OrderedDict in this case,
    this replaces it with a simple dict.

Mock out all RPC calls with a fixture
    
    Mock out the rpc proxy calls used by various agents to
    prevent unit tests from blocking for 10+ seconds while waiting
    for a timeout. This happened with the OVS agent unit tests
    recently in Change-ID Idd770a85a9eabff112d9613e75d8bb524020234a.
    
    This change results in a reduction from 330.8 seconds to 2.7 seconds
    for the neutron.tests.unit.openvswitch.test_ovs_neutron_agent
    test module.

Add logging for enforced policy rules
    
    There are a lot of policy rules which should not necessarily
    be explicitly specified in policy.json to be checked while enforcement.
    There should be a way for an operator to know which policy rules are
    actually being enforced for each action.
    
    Added a unit test.

DVR to delete router namespaces for service ports

Rework and enable VPNaaS UT for Cisco CSR REST
    
    The Cisco CSR REST client library unit tests were developed in
    Icehouse, using the httmock library. However, the community did
    not want to add this library to global requirements, as there was
    a similar httpretty library available (albeit with some short-
    comings). As a result, the test module was renamed with a "no"
    prefix, to prevent inclusion in automated tests.
    
    Since then, a new library, requests-mock, has been added to global
    requirements, to replace httpretty, and is being used on several
    other projects.
    
    This commit reworks the unit test to use requests-mock, instead of
    httmock. The functionality is the same, but the mechanism (a
    fixture with URI registration vs context manager) is different.
    
    This commit provides coverage for the REST client code, by using a
    mock for the Cisco CSR VM. The unit test module can be subclassed,
    and used with a real CSR VM, for 3rd party CI testing, in the
    future.

Delete DB records instead of tables to speedup UT
    
    Now that the schema is fixed for all of the plugins,
    there isn't a need to delete and recreate the entire
    schema for every unit test.
    
    This patch clears the tables at the end of each test
    instead of deleting them. This eliminated overhead seems
    to save 10%+ execution time of the entire set of unit
    tests.
    
    Example of performance gain from tox -epy27 tests.unit.ml2:
    Before: Ran 2495 tests in 284.186s
    After: Ran 2495 tests in 223.299s
