DVR:Removing an interface from router with multiple interfaces and with ext gw set does not remove interface from SNAT namespace

Bug #1479130 reported by Hardik Italia on 2015-07-28

This bug affects 3 people

Affects		Status	Importance	Assigned to	Milestone
	neutron	Fix Released	High	Swaminathan Vasudevan	neutron 7.0.0 "liberty"

Bug Description

Steps to reproduce:
1) Create one private and one public network.
2) Create DVR Router.
3) Add internal interface to router.
4) Set gateway to router. (qrouter & snat namespace should be created).
5) Remove internal interface from router (by port or by subnet)
6) Notice that corresponding SNAT interface for the internal network from SNAT namespace is still there.

So if we add internal interface again to a router then 2 SNAT interfaces for internal network will be there in the SNAT Namespace, which breaks external traffic for private subnet.

The internal CSNAT ports are not cached in the agent anymore and so the "get_snat_ports_for_the_internal_port" function fails, since it could not retrieve any CSNAT ports for the given subnet.

No network devices on network attached qos policies

Network devices, like internal router legs, or dhcp ports
should not be affected by bandwidth limiting rules.

This patch disables application of network attached policies

Use tempest-lib's token_client

    Now tempest-lib provides token_client modules as library and the
    interface is stable. So neutron repogitory doesn't need to contain
    these modules.
    This patch makes neutron use tempest-lib's token_client and removes
    the own modules for the maintenance.

Fix establishing UDP connection

    Previously, in establish_connection() for UDP protocol data were sent
    but never read on peer socket. That lead to successful read on peer side
    if this connection was filtered. Having constant testing string masked
    this issue as we can't distinguish to which test of connectivity data
    belong.

    This patch makes unique data string per test_connectivity() and
    also makes establish_connection() to create an ASSURED entry in
    conntrack table. Finally, in last test after firewall filter was
    removed, connection is re-established in order to avoid troubles with
    terminated processes or TCP continuing sending packets which weren't
    successfully delivered.

Prevent full sync in dhcp_agent when possible
    
    If an exception occurs in sync_state method, we try for a full sync
    even in the case where we have fewer networks to resync for.
    
    This turns out to be pretty costly in scaled environments.
    
    This patch addresses the above behavior by resyncing only for the
    eariler set of failed networks.

    one(AGENT_TYPE_NEC) is only used in out-of-tree networking-nec repo.
    This changes removes out-of-tree AGENT_TYPE_NEC constant (dependant
    change defines it in networking-nec repo).

func: Don't use private method of AsyncProcess
    
    In functional test we simulate crash of AsyncProcess by calling
    _kill_process(). This method is a private method and such usage
    introduced a race where process was respawned prior to calling wait() of
    killed process, leading to infinite wait on newly spawned process.
    
    This patch adds manual send of kill and then active waiting for process
    to be respawned, similarly like done with recent keepalived patch [1].

    Per [1] we are using a better way to keep tunnel connectivity,
    so reset_bridge isn't used anymore. Bug in [2] was caused by
    using method reset_bridge which will delete and recreate bridge.
    For [1] makes method reset_bridge deprecated, it makes sense to
    remove this method, and make [2] no longer produce.

Switch scheduler drivers to load based schedulers
    
    Cloud deployed at scale most likely will use these scheduler
    drivers because they allow a fairer resource allocation compared
    to chance schedulers (which randomly place resources on the hosts).
    
    Because of their importance, it's only wise to test them in
    the gate on a continuous basis, so that we do not get surprised
    by accidental regressions.
    
    Rather than pushing this down through devstack-gate/project-config
    patches, this chance alters the default of the scheduler
    drivers, so that users can also pick these up out of the box.
    
    This means that after an upgrade they would observe a change in
    the scheduling behavior, if they relied on the default config.

Fix BadRequest error on add_router_interface for DVR
    
    This operation for DVR is made of multiple steps, some of
    which are not within the same DB transaction. For this
    reason, if a failure occurs, the rollback will be partial.
    
    This inconsistent state leads the retry logic to fail with
    BadRequest, because the router is believed to be already
    connected to the subnet.
    
    To fix this condition, it is necessary to delete the port
    should the DB deadlock occur.

Tweak test_keepalived_respawns test logic
    
    This test initial design is problematic: it spawns keepalived,
    it asserts the process is up, then it attempts to kill it.
    
    However, this is when problems may arise:
    
    a) it does so by using the disable method on the process - we
       should be more rude than that if we want to simulate a crash!
    
    b) keepalived may be forking while it is starting and it is
       possible that for a moment the ppid changes and the process
       owner invoking the kill has no rights to kill the spawned
       process. This is the most plausible explaination I could find
       as to why kill returns 1 with no standard error
    
    c) it does not verify that the process has indeed disappeared
       (what if the pm.disable didn't work?) - this means that the
       test can pass, and yet the monitor may not work.
    
    Bottom line: this test relied on the correctness of the very code
    that was meant to validate...and that's not cool. To this aim, we
    wait for the process to be active, kill the process with a kill -9
    and verify that the process after the kill is indeed different.

Configure gw_iface for RAs only in Master HA Router
    
    For an HA Router which does not have any IPv6 subnets in the external network
    and when ipv6_gateway is not set, Neutron configures the gateway interface of
    the router to receive Router Advts for default route. In an HA router, only
    the Master instance has the IP addresses while the Backup instance does not
    have any addresses (including LLA). In Kernel version 3.10, when the last
    IPv6 address is removed from the interface, IPv6 proc entries corresponding
    to the iface are also deleted. This is however reverted in the later versions
    of kernel code.
    
    This patch addresses this issue by configuring the proc entry only for the
    Master HA Router instance instead of doing it un-conditionally.

Add tunneling support to full stack tests
    
    * EnvironmentDescription class now accepts 'network_type'.
      It sets the ML2 segmentation type, passes it to the OVS agents
      configuration files, and sets up the host configuration. If
      tunnelling type is selected, it sets up a veth pair with an IP
      address from the 240.0.0.1+ range. The addressed end of
      this pair is configured as the local_ip for tunneling purposes
      in each of the OVS agents. If network type is not tunnelled, it
      sets up provider bridges instead and interconnects them.
    * For now we run the basic L3 HA test with VLANs and tunneling just
      so we have something to show for.
    * I started using scenarios in fullstack tests to run the same test
      with VLANs or tunneling, and because test names are used for log
      dirs, and testscenarios changes test names to include characters
      that are not shell friendly (Space, parenthesis), I 'sanitized'
      some of those characters.

Descheduling DVR routers when ports are unbound from VM
    
    When a VM is deleted, the DVR port used by the VM could be unbound
    from the compute node. When it is unbounded, it is no longer
    in use on the node. Currently the unbind doesn't trigger a check
    to determine whether the DVR router can be unscheduled from the
    L3-agent running on the compute node. This patch makes the check
    and unschedule the router, if necessary.

Allow passing arbitrary ip route parameters to add/delete_route
    
    There are arguments to ip route like scope and dev that will need to
    be passed to add_route and delete_route.  This patch allows them to be
    passed using kwargs.

Make ip address optional to add_route and delete_route
    
    The add_route and delete_route methods require that the ip (actually
    "via" in ip route terms) be passed.  Some routes don't require this.
    This patch makes it optional while maintaining the position for those
    callers who do pass it by position.

Fix dvr update for subnet attach multi subnets
    
    Fix method dvr_update_router_addvm to notify every
    router attached to subnet where the vm will boot
    on.
    
    In dvr case, when a subnet only attaches to one router,
    the subnet will only have one distributed router interface,
    which device_owner is "network:router_interface_distributed".
    So in this case, get_ports in this method will only get
    one port, and it should be unnecessary to break in for loop.
    
    But when a subnet attaches multiple routers, get_ports in
    this method will return all distributed router interfaces
    and the routers hold those interfaces should be notified
    when an instance booted on the subnet. So it should also
    be unnecessary to break in for loop.

Make ip rule comparison more robust
    
    I found that ip rules would be added multiple times in new address
    scopes code because the _exists method was unable to reliably
    determine if the rule already existed.  This commit improves this by
    more robustly canonicalizing what it reads from the ip rule command so
    that like rules always compare the same.

Cleanup the fip agent gateway port delete routines
    
    Based on the parent patch, right now the Floatingip
    agent gateway ports will only be deleted when the
    last gateway port associated with the external
    network is deleted.
    
    The Floatingip agent gateway port will not be deleted
    for every floatingip dis-association and deletion.
    
    The Floatingip agent gateway port was created on all
    nodes as a substitute for the gateway port. So it
    makes sense to delete those ports only when the last
    gateway port on the external network is deleted.
    
    The agent should be able to delete the floatingip agent
    gateway port on a given external network when it is not
    required.
    
    This would substantially reduce the burden on the server
    to validate, read and delete the port form the DB.

Add RPC command and delete if last FIP on Agent
    
    Today FloatingIP Agent gateway port is deleted and
    re-created for DVR based routers based on floatingip
    association and disassociation with VMs on compute
    nodes by the plugin.
    
    This introduces lot more strain on the plugin to
    create and delete these ports when VMs come up and
    get deleted that are associated with FloatingIps.
    
    This patch will introduce an RPC call for the agent
    to initiate a agent gateway port delete.
    
    Also the agent will look for the last floatingip that
    it manages, and if condition satisfies, the agent will
    request the server to remove the FloatingIP Agent
    Gateway port.

Delete FIP agent gateway port with external gw port
    
    FIP agent gateway ports are associated with external
    networks and specific host.
    
    Today FIP agent gateway ports are deleted for
    every floatingip associate and disassociate. This
    introduces race conditions in the port delete and also
    un-necessary access to the db.
    
    This patch will delete the FIP agent gateway port when
    the last gateway port of the external network is deleted.
    
    The child patch linked to this parent patch will clean
    up the FIP agent gateway port delete when associate,
    disassociate and delete of floatingip happens.
    
    This should also cover the case when an agent for some
    reason was unable to request agent gw port delete.

Stop device_owner from being set to 'network:*'
    
    This patch adjusts the FieldCheck class in the policy engine to
    allow a regex rule. It then leverages that to prevent users from
    setting the device_owner field to anything that starts with
    'network:' on networks which they do not own.
    
    This policy adjustment is necessary because any ports with a
    device_owner that starts with 'network:' will not have any security
    group rules applied because it is assumed they are trusted network
    devices (e.g. router ports, DHCP ports, etc). These security rules
    include the anti-spoofing protection for DHCP, IPv6 ICMP messages,
    and IP headers.
    
    Without this policy adjustment, tenants can abuse this trust when
    connected to a shared network with other tenants by setting their
    VM port's device_owner field to 'network:<anything>' and hijack other
    tenants' traffic via DHCP spoofing or MAC/IP spoofing.

ovs agent resync may miss port remove event
    
    In OVS Agent rpc_loop() resync mechanism clears the registered ports and
    rescans them again, and it might result in missing some "port removed"
    event and treat_devices_removed will not be called.
    
    This fix rescans the newly updated ports when resync mechanism called,
    without clearing the current registered ports.
    
    The registered ports will be cleared only if there are too many
    consecutive resyncs to avoid resycing forever because of the same
    faulty port.

Retry metadata request on connection refused error
    
    This testcase may fail intermittently on 'Connection refused' error.
    This could be due to the fact that the metadata proxy setup is not exactly
    complete at the time the request is issued; in fact there is no
    synchronization between the router being up and the metadata request being
    issued, and clearly this may be the reason of accidental but seldom failures.
    
    In order to rule out this possibility and stabilize the test, let's retry
    on connection refused only. If we continue to fail, then the next step would
    be to dump the content of iptables to figure out why the error occurs.

Improve DB operations for quota reservation
    
    This patch deals with the lock wait timeout and the deadlock errors
    observed under high concurrency (api_workers >= 4) with the pymysql
    driver. It includes the following changes:
    
    - Stop setting dirty status for resource usage when creating
      reservation, as usage of reserved resources is not tracked anymore;
    - Add a variable, increasing delay when retrying make_reservation
      upon a DBDeadlock error in order to reduce the chances of further
      collisions;
    - Enable transaction retry upon DBDeadlock errors for set_quota_usage;
    - Do not resync quota usage while making reservation. This puts a lot
      of stress on the database and is also wasteful since resource usage
      is very likely to change again once the transaction is committed;
    - Use autonested_transaction to simplify logic around when the
      nested flag should be used.

Qos SR-IOV: Refactor extension delete to get mac and pci slot
    
    When calling delete we need the pci slot details to reset the VF rate. The problem
    is that when the VM is deleted libvirt return the VF to the hypervisor and eswitch
    manager will mark the pci_slot as unassigned so can't know from the mac which pci slot (VF)
    to reset. Also newer libvirt version reset the mac when deleteing VM, so than it is
    not possible at all.
    The solution is to keep pci slot details locally in the agent since upon removal event
    you cannot get pci_slot from the neutron server as it is for create/update since port
    is already removed from neutron.
    
    This patch pairs the mac and pci_slot for a device (VF) so when calling the extension
    port delete api we can have the pci_slot and reset the VF rate.
    
    It is also add a mapping between mac to port_id so we can pass the port_id
    when calling the extention port delete api.

OVS agent: handle deleted ports on each rpc_loop iteration
    
    Currently rpc loop processes ports only in case polling is required
    (message from ovsdb monitor) or there are port_updated notifications from
    server or security group notifications.
    In case of just port_deleted notifications port processing is not
    triggered during rpc loop.
    This may lead to agent accumulating a big amount of deleted ports
    and processing all of them at once during next iteration when polling is
    required or any notification from server, which might be quite tough for
    the agent. Tough means agent will be irresponsive while processing deleted
    ports.
    The patch makes port deletion processing more gradual.

Fix RBAC filter query for negative case
    
    The query to find networks that aren't shared to the querier was
    broken. It was querying for the inverse of RBAC entries that shared
    to the querier, so it would return the network for each other tenant
    it was shared to. This meant that if a network had multiple RBAC
    entries, a shared=False filter wouldn't work in the API.
    
    This patch corrects the behavior by adjusting the query that looks
    for objects not shared to the caller to make sure the object ID doesn't
    appear in the shared subquery.
    
    This patch also adds a test that reliably reproduces the original issue.
    The sporadically failing filter test that revealed this issue depended
    on a race to have a network be shared to another tenant and to the wildcard
    at the same time.

Fixed functional test that validates graceful ovs agent restart
    
    The async_ping function returns a callable that returns True when all ping
    futures are done. Since those futures are running for 10 secs, there was no
    chance that the result of the callable was True.
    
    The test was bailing out without calling bridge reset even a single time,
    effectively leaving the feature untested in gate.
    
    Another thing to note is that for some reason the patch fixed oslo rootwrap
    errors in the test when executed locally. Since I still don't understand how
    it's possible that it fixes the issue for me, I mark the bug as related only,
    and will track logstash after it's merged to see whether it applies unknown
    magic to gate jobs too.

Stop logging deadlock tracebacks
    
    The oslo db retry decorator logs a traceback everytime a deadlock
    is encountered even though it is being retried. With multiple workers
    and a Galera cluster, deadlocks are common occurences due to our use
    of with_lockmode update so we should not be polluting the logs.
    
    This patch adjusts our usage of the retry decorator to catch deadlocks
    with the exception checker which does not log them until the retries
    are exhausted.

sriov: update port state even if ip link fails
    
    Some SRIOV drivers/devices don't support link state setting,
    meaning that 'ip link' fails like this when trying to set state:
    
     # ip l set dev p2p1 vf 6 state disable
     RTNETLINK answers: Operation not supported
    
    The sriov-nic-agent tries to do that in
    SriovNicSwitchAgent.treat_device() and fails because of non-zero
    exit status from 'ip link' and, therefore, doesn't reach the code
    that updates the actual port status, so port could hang in a BUILD
    state even if binding was successful.
    
    This patch fixes problem of nova not being able to successfully bind
    or cleanup such a port. It does not fix a case when user manually
    updates admin_state_up for a port via API, it's subject to a separate
    fix.
    
    Also, replace LOG.exception with LOG.warning for set_device_state()
    as the exception would be logged by PciDeviceIPWrapper.set_vf_state()
    anyway.

Add support for PluginWorker and Process creation notification
    
    There are several cases where plugin initialization should be
    handled after neutron-server forks API/RPC workers. For example,
    starting a client connection to an SDN controller before forking
    copies the fd of the socket to the child process, but then you have
    multiple processes trying to read/write the same socket connection.
    
    It is also useful for a plugin to be able to do something in only
    one process, regardless of how many workers are forked. One example
    would be handling syncing from an external system to the neutron
    database.
    
    This patch does 3 things:
    1) Treats rpc_workers=0 as = 1. This simplifies the code for
       handling notification that forking has completed. In the
       existing code, calling the notification in the Worker object's
       start() method would happen twice in the case where both api
       and rpc workers were 0, despite there being only one process.
       An earlier patch already changed the default api_workers to be
       the number of processors.
    2) Adds notification of forking via the callbacks mechanism.
       Plugins can subscribe to resources.PROCESS, event.AFTER_CREATE
       and do any post-fork initialization that needs to be done for
       every spawned process.
    3) Adds core/service plugin calls to get_workers() which defaults
       to returning (). Plugins that need additional processes to spawn
       should just return an iterable of NeutronWorkers that will be
       spawned in their own process.

Add tenant_id to flavor service profiles attributes
    
    Neutron v2 base.py auto populates a 'tenant_id' attribute on
    calls if the attribute is not passed.  This causes a POST
    to create a flavor service binding to fail when verifying
    attributes with:
    Unrecognized attribute(s) 'tenant_id'
    
    Solution is to add tenant_id as expected attribute in the
    attribute map as done in other sub resources like QOS.
    
    Fix unit test for non-keystone case.

Remove implicit registration of *-aas service providers
    
    Implicit registration can be dropped when explicit registration
    for load balancer and vpn is implemented. Firewall does not
    use service providers and the ServiceTypeManager, so the
    precautionary step can be dropped altogether.
    
    Support for configuring providers via the service_providers section
    in neutron.conf, is no longer available, hence clear the stale
    entry points.

Process user iptables rules before INVALID
    
    Process user-defined iptables rules before the INVALID DROP
    rule. This is to allow scenarios where the VMs need to
    legitimately receive packets that conntrack doesn't have an
    entry for (e.g. SYN-ACK where the SYN wasn't sent by the VM).
    A user can accomplish this by adding an allow rule that matches
    the headers of these INVALID packets so they get permitted before
    they hit the INVALID DROP rule.

OVS-agent: Introduce Ryu based OpenFlow implementation
    
    Introduce an alternative OpenFlow implementation, "native",
    implemented using Ryu ofproto python library from Ryu SDN Framework.
    Make it selectable with of_driver=native agent option.
    The aim is to replace the existing ovs-ofctl based implementation
    eventually.
    
    It introduces node-local OpenFlow controller embedded in
    OVS agent.  Benefits include:
    * Reduce the overhead of invoking ovs-ofctl command (and associated
      rootwrap)
    * Make future uses of OpenFlow asynchronous messages (e.g. Packet-In,
      Port-Status, etc) easier
    * Make XenAPI integration simpler
    
    Highlights:
    * Switch to OpenFlow 1.3.
    * Make OVS-agent act as an OpenFlow controller
    * Configure OVS on the node to connect to the controller

Deprecate external_network_bridge option in L3 agent
    
    This option provides another way to attach to a specific bridge
    that is not quite equivalent with how bridge_mappings work in the
    L2 agent. This creates inconsistencies between how the L3 agent
    behaves when configured with a bridge_mapping and provider properties
    of the Neutron network vs. when it just ignores all L2 stuff and
    plugs itself directly into the bridge.
    
    See the bug report for more info.

Do not track active reservations
    
    Reservations have a transient nature: a reservation lifespan
    typically begins and ends with a single request.
    Therefore tracking reserved amounts for each tenant and resource
    is not nearly as efficient as tracking resource usage.
    Indeed it is fairly easy to verify that the overhead for tracking
    reserved amounts is much greater than the one needed for counting
    active reservations for each tenant and resource.
    
    This patch removes the logic for tracking reservations, and
    replaces it with an explicit count of active reservations.
    
    Please note that this patch does not adjust accordingly the
    ResourceUsage DB model. This will be done in a separate patch with
    an expand migration; this should avoid most merge conflicts before
    the final patch for restoring reservation logic merges.

Deprecate --service option for neutron-db-manage
    
    Now that https://review.openstack.org/198542 has merged we can
    deprecate the --service option. From now on instead of
      --service fwaas
    we should instead use
      --subproject neutron-fwaas
    
    This puts the *aas subprojects on equal footing with the other
    projects in the Neutron Stadium for neutron-db-manage.
    
    In the Liberty release the --service option will be marked as
    deprecated. It will be removed in Mitaka.

Add constraint target to tox.ini
    
    This adds a pip install command to tox.ini that is only used when the
    tox env is passed with the 'constraints' factor appended onto it.
    As such this will not effect developer workflows or current unit tests.
    
    The initial use of this will be in a non-voting job, to verify that the
    constrained checks with tox are stable.  DevStack is already running
    constrained jobs, as such problems are no expected.
    
    To run a tox with pip using constraints on a developer system a
    developer should run the desired tox environment with -constraints.
    For example: $(tox -epy27-constraints)
    Pip will pull the current version of the upper-constraints.txt file down
    from the git.openstack.org, however this method can be overriden to use
    a local file setting the environment variable "UPPER_CONSTRAINTS_FILE"
    to the local path or a different URL, it is passed directly to pip.
    
    This is currently not enabled in the default tox run, however it is
    possible to enable it as a default by adding it to 'envlist' in tox.ini

DHCP agent: allow using gateway IPs instead of uniquely allocated
    
    In each place where the DHCP agent runs, and for each subnet for which
    DHCP is handing out IP addresses, the DHCP port needs - at the Linux
    level - to have an IP address within that subnet.  Generally this
    needs to be a unique Neutron-allocated IP address, because the
    subnet's underlying L2 domain is bridged across multiple compute hosts
    and network nodes, and for HA there may be multiple DHCP agents
    running on that same bridged L2 domain.
    
    However, if the DHCP ports - on multiple compute/network nodes but for
    the same network - are _not_ bridged to each other, they do not need
    each to have a unique IP address.  Instead they can all share the same
    address from the relevant subnet.  This works, without creating any
    ambiguity, because those ports are not all present on the same L2
    domain, and because no data within the network is ever sent to that
    address.  (DHCP requests are broadcast, and it is the network's job to
    ensure that such a broadcast will reach at least one of the available
    DHCP servers.  DHCP responses will be sent _from_ the DHCP port
    address.)
    
    Specifically, for some networking backends it makes sense to allow all
    DHCP ports to use the subnet's gateway IP address, and thereby to
    completely avoid any unique IP address allocation.
    
    This change therefore enhances the DHCP agent code to be able to use
    gateway IPs as an alternative to uniquely allocated ones, with the
    choice between those being made by a new interface driver property,
    'use_gateway_ips'.  The back-compatible default is to use unique IPs.
    An interface driver that wants the DHCP agent to use gateway IPs can
    achieve that by overriding as follows:
    
        @property
        def use_gateway_ips(self):
            return True
