QoS: db models and migration rules This patch includes db models and migration rules for initial QoS objects. Comparing to the spec, it adds two more service tables to maintain links between networks and ports and their respective policies. We maintain uniqueness as a unique constraint. In some parallel world, we could have an additional field for networks and ports that could be nullable to point to a policy. That said, it breaks qos isolation a bit, and will also be a bit more painful if and when we decide to spin out qos service pieces outside the tree. blueprint quantum-qos-api Co-Authored-By: Ramanjaneya Co-Authored-By: vikram.choudhary Co-Authored-By: Ihar Hrachyshka Co-Authored-By: Miguel Angel Ajo Change-Id: I55a7dac602e2e770c21b6c7957430cb7115e5bdc --- .../versions/48153cb5f051_qos_db_changes.py | 79 ++++++++++++++++++ .../alembic_migrations/versions/HEAD | 2 +- neutron/db/migration/models/head.py | 1 + neutron/db/qos/__init__.py | 0 neutron/db/qos/models.py | 81 +++++++++++++++++++ 5 files changed, 162 insertions(+), 1 deletion(-) create mode 100755 neutron/db/migration/alembic_migrations/versions/48153cb5f051_qos_db_changes.py create mode 100644 neutron/db/qos/__init__.py create mode 100755 neutron/db/qos/models.py diff --git a/neutron/db/migration/alembic_migrations/versions/48153cb5f051_qos_db_changes.py b/neutron/db/migration/alembic_migrations/versions/48153cb5f051_qos_db_changes.py new file mode 100755 index 00000000000..7f79253d177 --- /dev/null +++ b/neutron/db/migration/alembic_migrations/versions/48153cb5f051_qos_db_changes.py @@ -0,0 +1,79 @@ +# Copyright 2015 Huawei Technologies India Pvt Ltd, Inc +# +# Licensed under the Apache License, Version 2.0 (the "License"); you may +# not use this file except in compliance with the License.

We can revisit this in a floow up patch if the whole notification logic should be moved somewhere else as this merits further discussion which is out of scope for a mere patch.

Any update would come in a single message, +doing only a single oslo versioned objects deserialization on each receiving +agent. + +This publishing/subscription mechanism is highly dependent on the format +of the resources passed around.

Old agents receive the updates on the old version + topic, new agents receive updates on the new version topic. + When the whole system upgraded, we un-pin the compatible version fanout. + + A variant of this could be using a single fanout queue, and sending the + pinned version of the object to all. Newer agents can deserialize to the + latest version and upgrade any fields internally. Again at the end, we + unpin the version and restart the service. + +b) The subscriber will rpc call the publisher to start publishing also a downgraded + version of the object on every update on a separate queue. The complication + of this version, is the need to ignore new version objects as long as we keep + receiving the downgraded ones, and otherwise resend the request to send the + downgraded objects after a certain timeout (thinking of the case where the + request for downgraded queue is done, but the publisher restarted). + This approach is more complicated to implement, but more automated from the + administrator point of view.

We need to reset changes, otherwise an object that is constructed and .create()d is different from the one that is .get_by_id()d from database (for primitive serialization contains list of changed fields for versioned objects). Added initial sql test case for objects (just create-fetch for policy for now, but can be easily extended to other types).

Also, expanded test_create() test to check all basic operations: get_by_id, create, update, and delete. To facilitate update() check, introduced a new field for objects called fields_to_update that stores names of fields that are not expected to be updated in an object. This allows us to keep the above mentioned test untangled from specific object type. Also made get_by_id() behave correctly (returning None) if the object does not exist.

A policy is then applied to a +network or a port, making all rules of the policy applied to the corresponding +Neutron resource (for a network, applying a policy means that the policy will +be applied to all ports that belong to it). + +From database point of view, following objects are defined in schema: + +* QosPolicy: directly maps to the conceptual policy resource. +* QosNetworkPolicyBinding, QosPortPolicyBinding: defines attachment between a + Neutron resource and a QoS policy. +* QosRule: defines common rule fields for all supported rule types. +* QosBandwidthLimitRule: defines rule fields that are specific to + bandwidth_limit type (the only type supported by the service as of time of + writing). + +There is a one-to-one relationship between QosRule and type specific +QosRule database objects. We represent the single object with two tables +to avoid duplication of common fields. (That introduces some complexity in +neutron objects for rule resources, but see below). + +All database models are defined under: + +* neutron.db.qos.models + +There is a long history of passing database dictionaries directly into business +logic of Neutron. This path is not the one we wanted to take for QoS effort, so +we've also introduced a new objects middleware to encapsulate the database logic +from the rest of the Neutron code that works with QoS resources. For this, we've +adopted oslo.versionedobjects library and introduced a new NeutronObject class +that is a base for all other objects that will belong to the middle layer. +There is an expectation that Neutron will evolve into using objects for all +resources it handles, though that part is obviously out of scope for the QoS +effort. + +Every NeutronObject supports the following operations: + +* get_by_id: returns specific object that is represented by the id passed as an + argument. +* get_objects: returns all objects of the type, potentially with a filter + applied. +* create/update/delete: usual persistence operations. + +Base object class is defined in: + +* neutron.objects.base + +For QoS, new neutron objects were implemented: + +* QosPolicy: directly maps to the conceptual policy resource, as defined above. +* QosBandwidthLimitRule: class that represents the only rule type supported by + initial QoS design. + +Those are defined in: + +* neutron.objects.qos.policy +* neutron.objects.qos.rule + +For QosPolicy neutron object, the following public methods were implemented: + +* get_network_policy/get_port_policy: returns a policy object that is attached + to the corresponding Neutron resource. +* attach_network/attach_port: attach a policy to the corresponding Neutron + resource. +* detach_network/detach_port: detach a policy from the corresponding Neutron + resource. + +In addition to the fields that belong to QoS policy database object itself, +synthetic fields were added to the object that represent lists of rules, +per-type, that belong to the policy. For example, to get a list of all +bandwidth_limit rules for a specific policy, a consumer of the object can just +access corresponding attribute via: + +* policy.bandwidth_limit_rules + +Implementation is done in a way that will allow adding a new rule list field +with little or no modifications in the policy object itself. This is achieved +by smart introspection of existing available rule object definitions and +automatic definition of those fields on the policy class. + +Note that synthetic fields are lazily loaded, meaning there is no hit into +the database if the field is not inspected by consumers. + +For QosRule objects, an extendable approach was taken to allow easy +addition of objects for new rule types. To accomodate this, all the methods +that access the database were implemented in a base class called QosRule that +is then inherited into type-specific rule implementations that, ideally, only +define additional fields and some other minor things. + +Note that the QosRule base class is not registered with oslo.versionedobjects +registry, because it's not expected that 'generic' rules should be +instantiated (and to enforce just that, the base rule class is marked as ABC). + +QoS objects rely on some primitive database API functions that are added in: + +* neutron.db.api +* neutron.db.qos.api + + +Callback changes +---------------- + +TODO(QoS): We're changing strategy here to not rely on AFTER_READ callbacks, + and foster discussion about how to do decouple core resource + extension in the community. So, update next phrase when that + happens. + +To extend ports and networks with qos_policy_id field, AFTER_READ callback +event is introduced. + +Note: a better mechanism is being built by @armax to make resource extensions +more explicit and under control. We will migrate to that better mechanism as +soon as it's available. + + +RPC communication +----------------- +Details on RPC communication implemented in reference backend driver are +discussed in `a separate page `_. + +One thing that should be mentioned here explicitly is that RPC callback +endpoints communicate using real versioned objects (as defined by serialization +for oslo.versionedobjects library), not vague json dictionaries. Meaning, +oslo.versionedobjects are on the wire and not just used internally inside a +component. + +There is expectation that after RPC callbacks are introduced in Neutron, we +will be able to migrate propagation from server to agents for other resources +(f.e. security groups) to the new mechanism. This will need to wait until those +resources get proper NeutronObject implementations. + + +Agent side design +================= + +To facilitate code reusability between agents and agent extensions without +patching the agent code itself, agent extensions were introduced.

Specific test classes can +obviously extend the set of test cases as they see needed (f.e. you need to +define new test cases for those additional methods that you may add to your +object implementations on top of base semantics common to all neutron objects). + From 0a33e355bcfb0a44ad3617f659ab452a04abdbdb Mon Sep 17 00:00:00 2001 From: Ihar Hrachyshka Date: Fri, 10 Jul 2015 18:00:34 +0200 Subject: [PATCH 036/112] objects.qos.policy: support per type rule lists as synthetic fields This is a significant piece of work. It enables neutron objects to define fields that are lazily loaded on field access. To achieve that, - field should be mentioned in cls.synthetic_fields - obj_load_attr should be extended to lazily fetch and cache the field Based on this work, we define per type rule fields that are lists of appropriate neutron objects. (At the moment, we have only single type supported, but I tried hard to make it easily extendable, with little or no coding needed when a new rule type object definition is added to rule.py: for example, we inspect object definitions based on VALID_RULE_TYPES, and define appropriate fields for the policy object). To implement lazy loading for those fields, I redefined get_by_id for rules that now meld fields from both base and subtype db models into the corresponding neutron object. Added a simple test that checks bandwidth_rules attribute behaves for policies. Some objects unit test framework rework was needed to accomodate synthetic fields that are not propagated to db layer.

For ML2 this means that that extend_{network,port}_dict functions will handle the extension of resources by calling QosExtensionHandler. This logic can easily be reused by other plugins. Note: we should make sure that resource extension does not require db access, otherwise we see DBDeadLock errors and random tempest failures. To achieve this, we define a new SQLAlchemy joined relationship on policy bindings to make networks and ports receive those bindings on their fetch from database. After that, the only work to do left for resource extension handler is to copy the fetched policy into resource dictionary. === Also enable new qos ml2 extension until we configure it in gate via project-config and devstack-gate to make sure it's enabled and tested.

This also contains 2 (very) simple tests which test creation and deletion of both policies and bandwidth rules, as well as list/show for both resources. While creation is done explicitly, deletion is done implicitly (all resources are deleted after the test, during tearDown) Minor fixes to the QoS plugin are included as well.

This is because for get_info(), we cannot propagate a class thru RPC but only a string that uniquely identifies the class. So it would be not optimal to require the server to discover the corresponding class from the type name passed from the agent. Also updated some comments in api/rpc/callbacks directory to reflect that we handle NeutronObjects, not dicts. Finally, killed the rule resource registration from QoS plugin and the rule type from supported resources since it's YAGNI at least now.

For ml2, determine supported qos rule types as a subset of rule types supported by all drivers. (In the future, we may expand the list to include all types supported by at least one of enabled drivers. This would require synchronized work with nova scheduler though.) For ml2, tests are limited, and should be expanded to check that common subset of qos rules is calculated properly when intersection != the list of each plugins.

This completes the CRUD tests and leaves the association/disassociation for a later patch. Note that deleting a rule isn't tested explicitly because of a bug with the rule delete logic on the server side. Once that code is fixed, the test should be added. to_dict() for policies should also convert any rules inside rule lists to dicts too, otherwise API layer receives rule object __repr__ strings instead of actual dicts. This patch introduces a fix to the existing to_dict() code to properly support policies. This patch also modifies the base infra to create policies and rules for admins and not for tenant.

Previously, policies that were created using the 'shared=True' flag were not accessible to other tenants, since the context used to search the policies was not elevated. This patch elevates the context prior to retrieving the policy, and if a match was found, makes sure that the user has permissions to access it (either the policy is shared or it's from the same tenant id). 2. Tests for both associations and disassociations of policies to both networks and ports are added in this patch, to make sure coverage is good and that the problem is fixed.

Both id fields point to qos_*_rules and qos_policies objects. Type is redundant since qos_rule and qos_*_rule objects maintain 1-to-1 relationship. Keeping a separate table just to link qos_*_rule and qos_policy objects has no meaning. At the same time, it complicates the code for rule objects significantly. So instead of copying with all those issues, we just squash the tables into single one. It allows us to reuse all base methods from NeutronObject for rules. LOC stats for the patch clearly shows the point: 65 insertions(+), 267 deletions(-) And no actual functionality is lost. While at it, the following changes were applied: - some base tests are reimplemented to test objects in a more explicit way; - fields_no_update class attribute is now actually enforced in base object class.

It also adds validation that the rules that are sent by the neutron-server are actually supported by the backend. Finally, port dict was not really enough to determine the name of the port in ovsdb. 'name' field is not really present in all port dicts, and does not reflect what is known to ovs anyway. So instead, we should rely on vif_port object to determine the ovs port name. Since ovs agent only added the vif_port value to details dict when binding was desired, I made adding the vif_port object unconditional, and covered that fact with unit tests. With this patch in place, I was able to get policy rules applied to a port in devstack installation. Functional tests will belong to a follow-up.

Better terms are chosen for two RPC APIs we have: - pull when a component actively requests a new object state; - push when a component updates anyone interested about an object change. Also, for callback registration, the following terms are used: - subscribe when a component is registered in consumer registry; - provide when a component is registered in provider registry. Covered the registries with some unit tests. Lots of existing tests utilize the registries now, and need to be isolated from other tests that mess with the managers (that are singletons), so introduced a common qos base test class to mock the manager with per-test instance of it).

Miguel Angel Ajo Date: Tue, 11 Aug 2015 13:51:16 +0200 Subject: [PATCH 111/112] Fix the low level OVS driver to really do egress It seems that the Queue + QoS + linux-htb implementation was really limiting ingress by default. So this patch switches the implementation to the ovs ingress_policing_rate and ingress_policing_burst parameters of the Interface table. Later in time we may want to revise this, to make TC & queueing possible, but this is good enough for egress limiting. Also, removed the _update_bandwidth_limit del+set on OvS QoS driver for the bandwidth limit rule update, since that's not needed anymore.
