Bug Description

When using tunnelling, if one of the hosts changed the hostname and tries to sync tunnels to neutron-server, this will throw an exception due to an unnecessary constraint, breaking the network.

Hostname changes are something neutron-server may survive to. Probably a log warning is enough, and the old hostname endpoint should be deleted.

This was found in HA deployments with pacemaker, where the hostname is roamed to the active node, or it's set dynamically on the nodes based on the clone ID provided by pacemaker, that's used to allow architectures like A/A/A/P/P for neutron, where one of the active nodes could die, and a passive takes the resources of the old active by roaming it's hostname (which is the logical ID where neutron agent resources are tied to).

How to reproduce:

1) Install a single node AIO with tunnelling for tenant networks.
2) openstack-config --set /etc/neutron/neutron.conf DEFAULT host newhostname
3) service neutron-openvswitch-agent restart
4) The exceptions keep happening for neutron-server in a loop as the agent tries to sync the tunnel, and fail.

This new behaviour was introduced in Kilo by this patch:

Remove duplicated call to setup_coreplugin

    The test case for vlan_transparent was calling setup_coreplugin
    before calling the super setUp method which already calls
    setup_coreplugin. This was causing duplicate core plugin fixtures
    which resulted in patching the dhcp periodic check twice.

Remove ensure_dirs double-patch

    test_spawn_radvd called mock.patch on ensure_dirs after the
    setup method already patched it out. This causes issues when
    mock.patch.stopall() is called because the mocks are stored
    as a set and are unwound in a non-deterministic fashion.[1]
    So some of the time they will be undone correctly, but others
    will leave a monkey-patched in mock, causing the ensure_dir
    test to fail.

Provide work around for 0.0.0.0/0 ::/0 for ipset
    
    Previously, the ipset_manager would pass in 0.0.0.0/0 or ::/0 if
    these addresses were inputted as allowed address pairs. This causes
    ipset to raise an error as it does not work with zero prefix sizes.
    To solve this problem we use two ipset rules to represent this:
    
    Ipv4: 0.0.0.0/1 and 128.0.0.1/1
    IPv6: ::/1' and '8000::/1
    
    All of this logic is handled via _sanitize_addresses() in the ipset_manager
    which is called to convert the input.

Make DHCPv6 out of bounds API test deterministic
    
    The test_dhcp_stateful_fixedips_outrange API test was randomly
    picking an IP from last + 1 up to last + 10 in the allocation
    range. This made it fail randomly when there was an issue related
    to the subnet allocation having an off-by-one issue.
    
    This adjusts the test to just always test last +1 and +2.

Don't process network_delete events on OVS agent
    
    There is no reason to reclaim the local VLAN on a network_delete
    event since it will be reclaimed when the last port is deleted anyway.
    
    This method was racey with recent port creation events and lead to
    occasional traces when it would yank the local VLAN out from underneath
    an ongoing port wiring process.

Support oslo_db 1.12
    
    oslo_db 1.12[1] decorates oslo_context.context.RequestContext with
    session management[2][3] and add a read-only attribute 'session'. Such
    feature breaks Brocade plugin and its unittests because they define
    on RequestContext the 'session' attribute which now is a read-only
    property. This change uses neutron.context instead of
    oslo_context.context in order to delegate session management to the
    neutron.context and remove read-only attribute set.
    
    A follow-up change will refactor neutron.context in order to use oslo_db
    1.12 session management instead of homemade one.

    - _validate_subnet_cidr
    - _validate_network_subnetpools
    - _allocate_pools_for_subnet
    - _save_subnet

Optimize ipset usage in IptablesFirewallDriver
    
    Currently, IptablesFirewallDriver._update_ipset_members() iterates
    through a list of security group IDs and makes a call to
    IpsetManager.set_members() for each security group ID in the list. The
    problem is that set_members() is repeatedly called with the same
    arguments over and over again because the list of security group IDs
    contains duplicates. These duplicated calls are unnecessary because they
    are idempotent.
    
    For instance, with a security group of 50 rules created in this manner:
        neutron security-group-rule-create $SECGRP --remote_group_id $SECGRP
            --protocol tcp --port_range_min $i --port_range_max $i
    
    Adding a server to that security group will cause 50 calls to
    IpsetManager.set_members() because the list of security group IDs is 50 of
    the same ID. Only one call to IpsetManager.set_members() is necessary
    per security group ID.
    
    This patch converts that list of security group IDs into a set, which
    eliminates the duplicate idempotent calls to
    IpsetManager.set_members() with the same arguments. This will affect
    performance by reducing the amount of file locking around ipset when
    adding servers to security groups.

Decompose DVR CSNAT L3 Agent from Compute Node L3 Agent
    
    Currently the same dvr router class is used both by the L3 Agent
    in the compute nodes that is responsible for the virtual routers
    namespace and the fip namespace and also used by the centralized
    SNAT L3 Agent in the network node.
    This is the first step to decompose the two into different
    classes.
    
    The above means that we have one class of DVR router which is used
    for two jobs (the virtual router namespace wiring and the fips wiring
    in the compute node in one hand and the centralized snat wiring in the other)
    The end goal of this patch is to separate the two into different classes
    which will also help maintaining it and also help projects that want
    to use one but not the other (for example only use the centralized
    SNAT behaviour with there own DVR implementation)

Fix l3 agent to not create already deleted router
    
    In case router is deleted during l3 agent resync,
    the "deleted" event is processed with higher priority, then
    resync event for the router may be processed which will recreate
    already deleted router.
    This happens due to timestamp not being properly updated for deleted
    router in router processor.
    The fix adds timestamp update for deleted router.
    
    Functional test will be updated in a follow-up patch
    
    Logging was improved to make debugging a bit easier.

Add request factory for pluggable IPAM
    
    Pluggable IPAM implementation requires separation between requesting
    address/subnet and it's actual allocation, which can happen on
    third-party IPAM servers. Request factory stands for simplifying
    building right request from input.
    
    Added AddressRequestFactory and SubnetRequestFactory.
    
    AddressRequestFactory creates instance of AnyAddressRequest or
    SpecificAddressRequest depending on presence of ip address in input.
    SubnetRequestFactory creates instance of AnySubnetRequest or
    SpecificSubnetRequest depending on input.
    
    get_subnet_request_factory and get_address_request_factory can be
    redefined on driver level to use custom request factories.

    Ironic expects neutron to have an "ipxe" tag for the option 175 which is

Add deadlock retry to API and ML2 RPC port update
    
    With the switch to the pymsql SQL driver, eventlet will now yield
    during database transactions. This greatly increased our probability
    of multiple coroutines running transactions on the same table that
    result in deadlocks.
    
    These deadlocks could result from many things including the following:
    * a coroutine holding a pessimistic "SELECT for UPDATE" lock when
      another tries to update the locked records
    * two coroutines both issue update statements using a WHERE clause
      invalidated by the other update (e.g. from a compare and swap approach)
    * two coroutines insert records that, when combined, violate a unique
      constraint on the table in a master-master Galera deployment
    * any two workers using "SELECT for UPDATE" in a master-master Galera
      deployment (write-set certification failure translates to deadlock)
    
    This problem is exacerbated by the switch to multiple API and RPC
    workers, each of which can lead to most of the errors above even
    without the switch to pymysql.
    
    This patch adds a deadlock retry decorator to the delete, create,
    and update methods at the HTTP API layer. Additionally, it adds a
    decorator to the update_port_status AMQP API in ML2 since it updates
    the port table, which is a heavily locked table by ML2 making it a
    prime candidate for deadlocks.
    
    Nova has had relied on the deadlock retry mechanism for quite some
    time now. We were limping along by not using additional workers and
    by relying on the unyielding nature of the MySQL C driver to
    serialize everything.

Remove duplicated debug logging around locking
    
    Currently, iptables_manager.py does extra unnecessary logging about lock
    acquisition and release. It uses lockutils.lock() which passes
    do_log=True by default, which causes lockutils.lock() to do debug
    logging about lock acquisition/release. IptablesManager itself also writes
    debug log info about lock acquisition and release.
    
    This change will eliminate unnecessary duplicate logging in order to
    reduce log noise about locking. This change is also related to
    https://github.com/harlowja/fasteners/commit/f88f2fea7fe250b7d26cdcbc84633ccbbc68eeee
    which reduces the logging level in the underlying lock implementation
    used by oslo.concurrency. That change along with this one will remove
    the duplicate debug logging about locking in iptables_manager.py and also in
    ipset_manager.py.

Refactor update_port in db_base_plugin_v2
    
    This commit is a preparation step for using pluggable IPAM.
    - moved validations into _validate_port_for_update;
    - updating ip addresses for port is backend specific, so
      moved into _update_port_with_ips in ipam_non_pluggable_backend;
    - writing port changes to db is common for both backends, so
      moved into _update_db_port in ipam_backend_mixin;
    - updated to use namedtuple to track add/original/remove ips;
    - added _make_fixed_ip_dict to exclude keys other than
      ip_address and subnet_id;

Refactor _update_ips_for_port
    
    This commit is a preparation step for using pluggable IPAM.
    _update_ips_for_port was refactored and split into two methods:
    - _get_changed_ips_for_port
      This method contains calculations common for pluggable and
      non-pluggable IPAM implementation, was moved to ipam_backend_mixin.
    - _update_ips_for_port
      This method is specific for non-pluggable IPAM implementation, so it
      was moved to ipam_non_pluggable_backend_common.
    
    Other changes:
    - _update_ips_for_port now returns namedtuple with added, removed, original
      ips (previously added and original ips were returned).
      List of removed ips is required by pluggable IPAM implementaion
      to apply rollback-on-failure logic;
    - removed unused port_id argument from _update_ips_for_port argument list;

Ensure no "db" related functional/fullstack tests are skipped in the gate
    
    Currently neutron uses MySQLTestCase[1] and
    PostgreSQLOpportunisticTestCase[2] for functional and fullstack tests
    using a real MySQL/PostgreSQL database. These classes skip tests when
    the db is unavailable (db not installed/configured, missing packages,
    etc.) which is fine when tests are runned by developers but not when
    runned by the gate jobs.
    
    This change updates MySQLTestCase[1] and defines PostgreSQLTestCase[1]
    as PostgreSQL oslo.db test class wrapper: when the db is unavailable,
    these classes ensure tests will:
    
    * fail in the gate (dsvm-functional, dsvm-fullstack jobs),
    * be skipped by default otherwise (functional, fullstack jobs).

Use PyMySQL in MySQL related functional/fullstack tests
    
    mysql-python driver has been replaced by PyMySQL driver[1] in neutron
    code but MySQL related functional/fullstack tests try to use
    mysql-python driver because of MySQLOpportunisticTestCase[2] and tests
    are skipped because mysql-python driver is no more available.
    
    This change provides a backend implementation for mysql+pymysql, a base
    base testcase MySQLTestCase[2] using mysql+pymysql implementation
    (currently oslo.db provides none of them but will in the future) and
    replaces MySQLOpportunisticTestCase with MySQLTestCase.

Stop sending gratuitous arp when ip version is 6
    
    This fix prevents calls to the arping utility for IPv6
    addresses, thereby eliminating errors reported by arping
    for IPv6 addresses.
    
    The assumption is that NDP, DAD, and RAs are sufficient
    for address resolution and duplicate address detection
    for IPv6, and that unsolicited Neighbor Advertisements (NAs)
    are not required for OpenStack services. If this turns out
    not to be the case for some service/feature, then a separate
    bug should be filed to add support for unsolicited NAs for
    that service.

Fix Enum usage in 589f9237ca0e_cisco_n1kv_ml2_driver_tables
    
    PostgreSQL is more sensitive with types than MySQL, it creates a

    type profile_type is trying to be created, but the type with such
    name was already created in havana_initial migration.
    
    The solution for this is not to create type in 589f9237ca0e

Ensure no "agent" functional tests are skipped in the gate
    
    Some "agent" functional tests[1] can be skipped if some requirements are
    not satisfied in order to allow developers to run functional tests on
    various environments. These tests should not be skipped in the gate.
    
    This change defines the decorator no_skip_on_missing_deps[2] to ensure
    no "agent" functional tests are skipped in the gate. More precisely
    no_skip_on_missing_deps transforms a skipTest into an error in:
    
    * dsvm-functional and dsvm-fullstack jobs,
    * functional and fullstack jobs when OS_FAIL_ON_MISSING_DEPS is
      evaluated as True.
    
    The change enlarges OS_FAIL_ON_MISSING_DEPS environment variable scope
    (ie: missing dependencies + system requirements).

Handle SIGHUP: neutron-server (multiprocess) and metadata agent
    
    All launchers implemented in common.service require each service to
    implement reset method because it is called in case a process
    receives a SIGHUP.
    
    This change adds the reset method to neutron.service.RpcWorker and
    neutron.wsgi.WorkerService which are used to wrap rpc and api
    workers correspondingly.
    
    Now neutron-server running in multiprocess mode (api_workers > 0 and
    rpc_workers > 0) and metadata agent don't die on receiving SIGHUP and support
    reloading policy_path and logging options in config.
    
    Note that reset is called only in case a service is running in daemon mode.
    
    Other changes made in the scope of this patch that need to be mentioned:
    
    * Don't empty self._servers list in RpcWorker's stop method
    
      When a service is restarted all services are gracefully shutdowned,
      resetted and started again (see openstack.common.service code).
      As graceful shutdown implies calling service.stop() and then
      service.wait() we don't want to clean self._servers list because
      it would be impossible to wait for them to stop processing
      requests and cleaning up their resources.
      Otherwise, this would lead to problems with rpc after starting
      the rpc server again.
    
    * Create a duplicate socket each time WorkerService starts
    
      When api worker is stopped it kills the eventlet wsgi server
      which internally closes the wsgi server socket object. This server
      socket object becomes not usable which leads to "Bad file
      descriptor" errors on service restart.
    
    Added functional and unit tests.

Remove get_admin_roles and associated logic
    
    get_admin_roles was introduced so that contextes generated from
    within plugins could be used for policy checks. This was the case
    up to the Havana release as several plugins invoked the policy
    engine directly to authorize requests.
    
    This was an incorrect behaviour and has now been fixed, meaning
    that get_admin_roles is no longer need and can be safely removed.
    This will result in a leaner and more reliable codebase. Indeed the
    function being removed here was the cause of several bugs where the
    policy engine was initialized too early in the server bootstrap
    process.
    While this patch removes the feature it does not remove the
    load_admin_roles parameter from context.get_admin_context. Doing so
    will break other projects such as neutron-lbaas. The parameter is
    deprecated by this patch and an appropriate warning emitted.
    
    As a consequence neutron's will now no longer perform policy checks
    when context.is_admin=True. This flag is instead set either when
    a context is explicitly created for granting admin privileges, or
    when Neutron is operating in noauth mode. In the latter case every
    request is treated by neutron as an admin request, and get_admin_roles
    is simply ensuring the appropriate roles get pushed into the context
    so that the policy engine will grant admin rights to the request.
    This behaviour is probably just a waste of resource; also it is not
    adding anything from a security perspective.
    
    On the other hand not performing checks when context.is_admin is
    True should not pose a security threat either in noauth mode or
    with the keystone middleware. In the former case the software keeps
    operating assuming admin rights for every requests, whereas in the
    latter case the keystone middleware will always supply a context
    with the appropriate roles, and there is no way for an attacker
    to trick keystonemiddleware into generating a context for which
    is_admin=True.
    
    Finally, this patch also does some non-trivial changes in test_l3.py
    as some tests were mocking context.to_dict ignoring the is_admin flag.

Ensure netfilter is enabled for bridges
    
    Since security-groups use iptables rules on Linux bridges, we need to
    ensure that netfilter is enabled for bridges.  Unfortunately, there
    seems to be a long history of distributions having differing defaults
    for this, best described in [1].
    
    It seems at the moment everyone has to discover this for themselves;
    packstack found it in Ia8c86dcb31810a8d6b133a161388604fde9bead4, then
    fuel found the same thing in I8582c24706c3a7253e00569eef275f116d765bca
    and then finally someone else hit it and put it into documentation
    with I4ed3cec03a1b3a7d56dfe18394154ec1b2db6791.  I just spent a long
    time figuring it out too when deploying with devstack.
    
    Rather than having yet another fix in devstack, I don't see why
    neutron shouldn't be ensuring the setting is correct when it starts up
    -- without these settings enabled, security-groups are silently
    broken.  This does that, and modifies test-cases to check we make the

Ensure non-overlapping cidrs in subnetpools without galera
    
    _get_allocated_cidrs[1] locks only allocated subnets in a subnetpool
    (with mysql/postgresql at least). It ensures we don't allocate a cidr
    overlapping with existent cidrs but nothing disallows a concurrent
    subnet allocation to create a subnet in the same subnetpool.
    
    This change replaces the lock on subnetpool subnets by a lock on the
    subnetpool itself. It disallows to allocate concurrently 2 subnets in
    the same subnetpool and ensure non-overlapping cidrs in the same
    subnetpool.
    
    Moreover this change solves a trouble with postgresql which disallows
    to lock an empty select with an outer join: it happens on first subnet
    allocation in a subnetpool when no specific cidr is provided. Moving
    the lock ensures the lock is done on a non-empty select.
    
    But this change does not ensure non-overlapping cidrs in subnetpools
    with galera because galera doesn't support SELECT FOR UPDATE locks. A
    follow-up change will (try to?) remove locks from subnet allocation[1]
    in order to ensure non-overlapping cidrs in subnetpools also with galera.

Don't resync on DHCP agent setup failure
    
    There are various cases where the DHCP agent will try to
    create a DHCP port for a network and there will be a failure.
    This has primarily been caused by a lack of available IP addresses
    in the allocation pool. Trying to fix all availability corner cases
    on the server side will be very difficult due to race conditions between
    multiple ports being created, the dhcp_agents_per_network parameter, etc.
    
    This patch just stops the resync attempt on the agent side if a failure
    is caused by an IP address generation problem. Future updates to the subnet
    will cause another attempt so if the tenant does fix the issue they will
    get DHCP service.

tests: confirm that _output_hosts_file does not log too often
    
    I3ad7864eeb2f959549ed356a1e34fa18804395cc didn't include any regression unit
    tests to validate that the method won't ever log too often again,
    reintroducing performance drop in later patches. It didn't play well
    with stable backports of the fix, where context was lost when doing the
    backport, that left the bug unfixed in stable/juno even though the patch
    was merged there [1].
    
    The patch adds an explicit note in the code that suggests not to add new
    log messages inside the loop to avoid regression, and a unit test was
    added to capture it.
    
    Once the test is merged in master, it will be proposed for stable/juno
    inclusion, with additional changes that would fix the regression again.

Restrict subnet create/update to avoid DHCP resync
    
    As we know, IPs in subnet CIDR are used for
    1) Broadcast port
    2) Gateway port
    3) DHCP port if enable_dhcp is True, or update to True
    4) Others go into allocation_pools
    Above 1) to 3) are created by default, which means if CIDR doesn't
    have that much of IPs, subnet create/update will cause a DHCP resync.
    
    This fix is to add some restricts to the issue:
    A) When subnet create, if enable_dhcp is True, /31 and /32
       cidrs are forbidden for IPv4 subnets while /127 and /128 cidrs are
       forbidden for IPv6 subnets.
    B) When subnet update, if enable_dhcp is changing to True and there are no
       more IPs in allocation_pools, the request should be denied.

ML2: Change port status only when it's bound to the host
    
    Currently, nothing prevents the port status to be changed to BUILD
    state when get_device_details() is sent by a host that doesn't own
    the port.
    In some cases the port might stay in BUILD state.
    This could happen during a live-migration, or for multi-hosted ports
    such as HA ports.
    This commit allows the port status modification only if the port
    is bound to the host that is asking for it.

Fixes race condition and boosts the scheduling performance
    
    This patch fixes a race-condition that occurs when the
    scheduler tries to check for dvr serviceable ports before
    it schedules a router when a subnet is associated with
    a router.
    
    Sometimes the dhcp port creation is delayed and so the
    router is not scheduled to the l3-agent.
    
    Also it boosts the scheduling performance on dvr-snat
    node for scheduling a router.
    
    This patch will provide a work around to fix this race
    condition and to boost the scheduling performance
    by scheduling a router on a dvr-snat when
    dhcp is enabled on the provided subnet, instead of checking
    all the available ports on the subnet.

Set IPset hash type to 'net' instead of 'ip'
    
    The previous hash type was 'ip' and this caused a major
    issue with the allowed address pairs extension since it
    results in CIDRs being passed to ipset. When the hash type
    is 'ip', a CIDR is completely enumerated into all of its
    addresses so 10.100.0.0/16 results in ~65k entries. This
    meant a single allowed_address_pairs entry could easily
    exhaust an entire set.
    
    This patch changes the hash type to 'net', which is designed
    to handle a CIDRs as a single entry.
    
    This patch also changes the names of the ipsets because
    creating an ipset with different parameters will cause an
    error and our ipset manager code isn't robust enough to handle
    that at this time. There is another ongoing patch to fix
    that but it won't be ready in time.[1]
    
    The related bug was closed by increasing the set limit, which
    did alleviate the problem. However, this change would also
    address the issue because the gate tests run an allowed address
    pairs extension test with the CIDR mentioned above.

    - and a naive `apt-get install python-tox; tox -epep8` fails with
    py3-related errors on Debian.
    
    This change explicitly sets `basepython = python2.7` in several testing
    environments that would otherwise have used the default basepython.

Ran into this issue as well in Kilo where my node initially came up with the hostname "localhost.localdomain", and then I corrected it to the proper name.

These are the steps I did to correct my setup, but may not be complete, so use with caution.

I first ran "neutron agent-list" and then "neutron agent-delete $id" of the id associated with localhost.localdomain.
That didn't correct it fully, and not sure if this step was needed.

So I then accessed the neutron database and ran

this was the incorrect entry mapping the ip to localhost.localdomain instead of the correct entry.

So i ran
delete from ml2_gre_endpoints where host='localhost.localdomain';

Next, on the bad compute node did " systemctl restart neutron-openvswitch-agent.service"

And that made everything work for me. The database table was updated after the restart by openstack to contain the new correct entry.

You may have to look in ml2_vxlan_endpoints, depending on your setup.

Hi,

Thanks Keith!

I confirmed that your solution works for me too. I had "NULL" in the table and once I set the correct host name its working fine.

Thanks for your suggestion.

Regards..
Salman.

Hello,

FWIW, I can confirm this worked using ml2_vxlan_endpoints also on Kilo with CentOS 7.1

Thanks for the fix.

Fix hostname roaming for ml2 tunnel endpoints.

    Change I75c6581fcc9f47a68bde29cbefcaa1a2a082344e introduced
    a bug where host name changes broke tunneling endpoint updates.
    Tunneling endpoint updates roaming a hostname from IP to IP
    are a common method for active/passive HA with pacemaker and
    should happen automatically without the need for API/CLI calls [1].

    delete_endpoint_by_host_or_ip is introduced to allow cleanup of
    endpoints that potentially belonged to the newly registered agent,
    while preventing the race condition found when deleting ip1 & ip2
    in the next situation at step 4:

    1) we have hostA: ip1
    2) hostA goes offline
    3) hostB goes online, with ip1, and registers
    4) hostA goes online, with ip2, and registers

We're also seeing this on Kilo - a backport of the fix would be hugely appreciated.
