The documents is organized into the following sections: * TaaS Resources * API Reference * TaaS CLI Reference * Workflow TaaS Resources ============== TaaS consists of two resources, TapService and TapFlow. TapService ---------- TapService Represents the port on which the mirrored traffic is delivered. Any service (VM) that uses the mirrored data is attached to the port. .. code-block:: python 'tap_services': { 'id': {'allow_post': False, 'allow_put': False, 'validate': {'type:uuid': None}, 'is_visible': True, 'primary_key': True}, 'tenant_id': {'allow_post': True, 'allow_put': False, 'validate': {'type:string': None}, 'required_by_policy': True, 'is_visible': True}, 'name': {'allow_post': True, 'allow_put': True, 'validate': {'type:string': None}, 'is_visible': True, 'default': ''}, 'description': {'allow_post': True, 'allow_put': True, 'validate': {'type:string': None}, 'is_visible': True, 'default': ''}, 'port_id': {'allow_post': True, 'allow_put': False, 'validate': {'type:uuid': None}, 'is_visible': True}, } TapFlow ------- TapFlow Represents the port from which the traffic needs to be mirrored. .. code-block:: python 'tap_flows': { 'id': {'allow_post': False, 'allow_put': False, 'validate': {'type:uuid': None}, 'is_visible': True, 'primary_key': True}, 'tenant_id': {'allow_post': True, 'allow_put': False, 'validate': {'type:string': None}, 'required_by_policy': True, 'is_visible': True}, 'name': {'allow_post': True, 'allow_put': True, 'validate': {'type:string': None}, 'is_visible': True, 'default': ''}, 'description': {'allow_post': True, 'allow_put': True, 'validate': {'type:string': None}, 'is_visible': True, 'default': ''}, 'tap_service_id': {'allow_post': True, 'allow_put': False, 'validate': {'type:uuid': None}, 'required_by_policy': True, 'is_visible': True}, 'source_port': {'allow_post': True, 'allow_put': False, 'validate': {'type:uuid': None}, 'required_by_policy': True, 'is_visible': True}, 'direction': {'allow_post': True, 'allow_put': False, 'validate': {'type:values': direction_enum}, 'is_visible': True}, 'vlan_filter': {'allow_post': True, 'allow_put': False, 'validate': {'type:regex_or_none': RANGE_REGEX}, 'is_visible': True, 'default': None} } direction_enum = ['IN', 'OUT', 'BOTH'] Multiple TapFlow instances can be associated with a single TapService instance. API REFERENCE ============= https://docs.openstack.org/api-ref/network/v2/index.html#tap-as-a-service TaaS CLI Reference ================== Openstack CLI ------------- OpenStackClient provides `the basic network commands `__ and tap-as-a-service has an extension for taas related commands. * Create tap service: **openstack tap service create** --name --port * List tap services: **openstack tap service list** * Show tap service: **openstack tap service show** * Delete tap service: **openstack tap service delete** * Update tap service: **openstack tap service update** --name --description * Create tap flow: **openstack tap flow create** --name --port --tap-service --direction --vlan-filter * List tap flows **openstack tap flow list** * Show tap flow **openstack tap flow show** * Delete tap flow **openstack tap flow delete** * Update tap flow **openstack tap flow update** --name --description Workflow ========= In this section we describe a simple sequence of steps to use TaaS. Workflow Sequence ------------------ 1. Create a Neutron port with 'port_security_enabled' set to 'false'. 2. Launch a VM (VM on which you want to monitor/receive the mirrored data). Associate the Neutron port created in step 1 while creating the VM. 3. Using Neutron Client command for TaaS **neutron tap-service-create** or via REST APIs create a Tap Service instance by associating the port created in step 1. 4. Using Neutron Client command for TaaS **neutron tap-flow-create** or via REST APIs create a Tap Flow instance by associating the Tap Service instance created in step 3 and the target Neutron port from which you want to mirror traffic (assuming the Neutron port from which the traffic needs to be monitored already exists.) Mirroring can be done for both incoming and/or outgoing traffic from the target Neutron port. 5. Observe the mirrored traffic on the monitoring VM by running tools such as tcpdump. ././@PaxHeader0000000000000000000000000000002600000000000011453 xustar000000000000000022 mtime=1727867409.0 tap-as-a-service-14.0.0/AUTHORS0000664000175000017500000000427000000000000015733 0ustar00zuulzuul00000000000000Abhishek Raut Andrea Frittoli Andreas Jaeger Anh Tran Anil Rao Boden R Corey Bryant Deepak Tiwari Dongcan Ye Doug Hellmann Duong Ha-Quang Elod Illes Fawad Khaliq Felipe Figueroa Gary Kotton Ghanshyam Mann Hangdong Zhang Henry Gessau Henry Gessau Ian Wienand James Page Jeremy Stanley Juan Pablo Suazo Kazuhiro Suzuki Monty Taylor Nguyen Hung Phuong Ondřej Nový OpenStack Release Bot Reedip Reedip Reedip Reedip Banerjee Robert Simon Rodolfo Alonso Hernandez Rui Zang Slawek Kaplonski Takashi Kajinami Thomas Morin Trevor McCasland Viktor Krivak YAMAMOTO Takashi Yatin Kumbhare Yoichiro Iura bhavani.cr bk160f cheng daohanli elajkat ghanshyam huang.zhiping jessegler liyou01 reedip ricolin sunqingliang6 venkatamahesh vnyyad yatinkarel zitptan zoushilin ././@PaxHeader0000000000000000000000000000002600000000000011453 xustar000000000000000022 mtime=1727867378.0 tap-as-a-service-14.0.0/CONTRIBUTING.rst0000664000175000017500000000122600000000000017322 0ustar00zuulzuul00000000000000If you would like to contribute to the development of OpenStack, you must follow the steps in this page: https://docs.openstack.org/infra/manual/developers.html If you already have a good understanding of how the system works and your OpenStack accounts are set up, you can skip to the development workflow section of this documentation to learn how changes to OpenStack should be submitted for review via the Gerrit tool: https://docs.openstack.org/infra/manual/developers.html#development-workflow Pull requests submitted through GitHub will be ignored.

=================================== This is the installation guide for enabling Tap-as-a-Service(TaaS) feature in OpenStack Neutron We have tested TaaS with latest version DevStack running on Ubuntu 12.04 and 14.04. TaaS is currently under active development and we will update you of new features and capabilities as and when they become available. Feel free to approach us with any issues related to installing or using TaaS. Dependencies ============ TaaS requires the 'Port Security' Neutron ML2 extension.

Home-page: http://www.openstack.org/ Author: OpenStack Author-email: openstack-discuss@lists.openstack.org License: UNKNOWN Description: ================ Tap as a Service ================ Tap-as-a-Service (TaaS) is an extension to the OpenStack network service (Neutron). It provides remote port mirroring capability for tenant virtual networks. Port mirroring involves sending a copy of packets entering and/or leaving one port to another port, which is usually different from the original destinations of the packets being mirrored. This service has been primarily designed to help tenants (or the cloud administrator) debug complex virtual networks and gain visibility into their VMs, by monitoring the network traffic associated with them. TaaS honors tenant boundaries and its mirror sessions are capable of spanning across multiple compute and network nodes. It serves as an essential infrastructure component that can be utilized for supplying data to a variety of network analytics and security applications (e.g. IDS). * Free software: Apache license * API Reference: https://opendev.org/openstack/tap-as-a-service/src/branch/master/API_REFERENCE.rst * Source: https://opendev.org/openstack/tap-as-a-service/ * Bugs: https://bugs.launchpad.net/tap-as-a-service For installing Tap-as-a-Service with Devstack please read the INSTALL.rst file Platform: UNKNOWN Classifier: Environment :: OpenStack Classifier: Intended Audience :: Information Technology Classifier: Intended Audience :: System Administrators Classifier: License :: OSI Approved :: Apache Software License Classifier: Operating System :: POSIX :: Linux Classifier: Programming Language :: Python Classifier: Programming Language :: Python :: 3 Classifier: Programming Language :: Python :: 3.8 Classifier: Programming Language :: Python :: 3.9 ././@PaxHeader0000000000000000000000000000002600000000000011453 xustar000000000000000022 mtime=1727867378.0 tap-as-a-service-14.0.0/README.rst0000664000175000017500000000230100000000000016343 0ustar00zuulzuul00000000000000================ Tap as a Service ================ Tap-as-a-Service (TaaS) is an extension to the OpenStack network service (Neutron).

Adds a new TaaS Agent driver (i.e. SRIOV) for Intel i40e driver backend. * Neutron TaaS Agent is refactored to decouple its tight binding with ovs driver. This prepares the taas agent code-base for addition of a new TaaS Agent driver (SRIOV). * Adds a new API extension, i.e. taas-vlan-filter for adding a new attribute (vlan_filter) in tap-flow data model. ././@PaxHeader0000000000000000000000000000002600000000000011453 xustar000000000000000022 mtime=1727867378.0 tap-as-a-service-14.0.0/releasenotes/notes/clear-tap-resources-on-port-delete-9583cdd7cd6098ea.yaml0000664000175000017500000000064300000000000032420 0ustar00zuulzuul00000000000000--- prelude: > Deleting a port associated with some tap resources (tap service or tap flow) shall now cascade delete those associated tap resources as well.

This work is licensed under a Creative Commons Attribution 3.0 Unported License. http://creativecommons.org/licenses/by/3.0/legalcode ============================ Tap-as-a-Service for Neutron ============================ Launchpad blueprint: https://blueprints.launchpad.net/neutron/+spec/tap-as-a-service This spec explains an extension for the port mirroring functionality. Port mirroring involves sending a copy of packets ingressing and/or egressing one port (where ingress means entering a VM and egress means leaving a VM) to another port, (usually different from the packet's original destination). A port could be attached to a VM or a networking resource like router. While the blueprint describes the functionality of mirroring Neutron ports as an extension to the port object, the spec proposes to offer port mirroring as a service, which will enable more advanced use-cases (e.g. intrusion detection) to be deployed. The proposed port mirroring capability shall be introduced in Neutron as a service called "Tap-as-a-Service". Problem description =================== Neutron currently does not support the functionality of port mirroring for tenant networks. This feature will greatly benefit tenants and admins, who want to debug their virtual networks and gain visibility into their VMs by monitoring and analyzing the network traffic associated with them (e.g. IDS). This spec focuses on mirroring traffic from one Neutron port to another; future versions may address mirroring from a Neutron port to an arbitrary interface (not managed by Neutron) on a compute host or the network controller. Different usage scenarios for the service are listed below: 1. Tapping/mirroring network traffic ingressing and/or egressing a particular Neutron port. 2. Tapping/mirroring all network traffic on a tenant network. 3. Tenant or admin will be able to do tap/traffic mirroring based on a policy rule and set destination as a Neutron port, which can be linked to a virtual machine as normal Nova operations or to a physical machine via l2-gateway functionality. 4. Admin will be able to do packet level network debugging for the virtual network. 5. Provide a way for real time analytics based on different criteria, like tenants, ports, traffic types (policy) etc. Note that some of the above use-cases are not covered by this proposal, at least for the first step. Proposed change =============== The proposal is to introduce a new Neutron service plugin, called "Tap-as-a-Service", which provides tapping (port-mirroring) capability for Neutron networks; tenant or provider networks. This service will be modeled similar to other Neutron services such as the firewall, load-balancer, L3-router etc. The proposed service will allow the tenants to create a tap service instance to which they can add Neutron ports that need to be mirrored by creating tap flows. The tap service itself will be a Neutron port, which will be the destination port for the mirrored traffic. The destination Tap-as-a-Service Neutron port should be created beforehand on a network owned by the tenant who is requesting the service. The ports to be mirrored that are added to the service must be owned by the same tenant who created the tap service instance. Even on a shared network, a tenant will only be allowed to mirror the traffic from ports that they own on the shared network and not traffic from ports that they do not own on the shared network. The ports owned by the tenant that are mirrored can be on networks other than the network on which tap service port is created. This allows the tenant to mirror traffic from any port it owns on a network on to the same Tap-as-a-Service Neutron port. The tenant can launch a VM specifying the tap destination port for the VM interface (--nic port-id=tap_port_uuid), thus receiving mirrored traffic for further processing (dependent on use case) on that VM. The following would be the work flow for using this service from a tenant's point of view 0. Create a Neutron port which will be used as the destination port. This can be a part of ordinary VM launch. 1. Create a tap service instance, specifying the Neutron port. 2. If you haven't yet, launch a monitoring or traffic analysis VM and connect it to the destination port for the tap service instance. 3. Associate Neutron ports with a tap service instance if/when they need to be monitored. 4. Disassociate Neutron ports from a tap service instance if/when they no longer need to be monitored. 5. Destroy a tap-service instance when it is no longer needed. 6. Delete the destination port when it is no longer neeeded. Please note that the normal work flow of launching a VM is not affected while using TaaS. Alternatives ------------ As an alternative to introducing port mirroring functionality under Neutron services, it could be added as an extension to the existing Neutron v2 APIs.

{'allow_post': False, 'allow_put': False, 'is_visible': True}, } } Security impact --------------- A TaaS instance comprises a collection of source Neutron ports (whose ingress and/or egress traffic are being mirrored) and a destination Neutron port (where the mirrored traffic is received). Security Groups will be handled differently for these two classes of ports, as described below: Destination Side: Ingress Security Group filters, including the filter that prevents MAC-address spoofing, will be disabled for the destination Neutron port. This will ensure that all of the mirrored packets received at this port are able to reach the monitoring VM attached to it. Source Side: Ideally it would be nice to mirror all packets entering and/or leaving the virtual NICs associated with the VMs that are being monitored. This means capturing ingress traffic after it passes the inbound Security Group filters and capturing egress traffic before it passes the outbound Security Group filters. However, due to the manner in which Security Groups are currently implemented in OpenStack (i.e. north of the Open vSwitch ports, using Linux IP Tables) this is not possible because port mirroring support resides inside Open vSwitch. Therefore, in the first version of TaaS, Security Groups will be ignored for the source Neutron ports; this effectively translates into capturing ingress traffic before it passes the inbound Security Group filters and capturing egress traffic after it passes the outbound Security Group filters. In other words, port mirroring will be implemented for all packets entering and/or leaving the Open vSwitch ports associated with the respective virtual NICs of the VMs that are being monitored. There is a separate effort that has been initiated to implement Security Groups within OpenvSwitch. A later version of TaaS may make use of this feature, if and when it is available, so that we can realize the ideal behavior described above. It should be noted that such an enhancement should not require a change to the TaaS data model. Keeping data privacy aspects in mind and preventing the data center admin from snooping on tenant's network traffic without their knowledge, the admin shall not be allowed to mirror traffic from any ports that belong to tenants. Hence creation of 'Tap_Flow' is only permitted on ports that are owned by the creating tenant. If an admin wants to monitor tenant's traffic, the admin will have to join that tenant as a member. This will ensure that the tenant is aware that the admin might be monitoring their traffic. Notifications impact -------------------- A set of new RPC calls for communication between the TaaS server and agents are required and will be put in place as part of the reference implementation. IPv6 impact -------------------- None Other end user impact --------------------- Users will be able to invoke and access the TaaS APIs through python-neutronclient. Performance Impact ------------------ The performance impact of mirroring traffic needs to be examined and quantified. The impact of a tenant potentially mirroring all traffic from all ports could be large and needs more examination. Some alternatives to reduce the amount of mirrored traffic are listed below. 1. Rate limiting on the ports being mirrored. 2. Filters to select certain flows ingressing/egressing a port to be mirrored. 3. Having a quota on the number of TaaS Flows that can be defined by the tenant. Other deployer impact --------------------- Configurations for the service plugin will be added later. A new bridge (br-tap) mentioned in Implementation section. Developer impact ---------------- This will be a new extension API, and will not affect the existing API. Community impact ---------------- None Follow up work -------------- Going forward, TaaS would be incorporated with Service Insertion [2]_ similar to other existing services like FWaaS, LBaaS, and VPNaaS. While integrating Tap-as-a-Service with Service Insertion the key changes to the data model needed would be the removal of 'network_id' and 'port_id' from the 'Tap_Service' data model. Some policy based filtering rules would help alleviate the potential performance issues. We might want to ensure exclusive use of the destination port. We might want to create the destination port automatically on tap-service creation, rather than specifying an existing port. In that case, network_id should be taken as a parameter for tap-service creation, instead of port_id. We might want to allow the destination port be used for purposes other than just launching a VM on it, for example the port could be used as an 'external-port' [1]_ to get the mirrored data out from the tenant virtual network on a device or network not managed by openstack. We might want to introduce a way to tap a whole traffic for the specified network. We need a mechanism to coordinate usage of various resources with other agent extensions. E.g. OVS flows, tunnel IDs, VLAN IDs. Implementation ============== The reference implementation for TaaS will be based on Open vSwitch. In addition to the existing integration (br-int) and tunnel (br-tun) bridges, a separate tap bridge (br-tap) will be used. The tap bridge provides nice isolation for supporting more complex TaaS features (e.g. filtering mirrored packets) in the future. The tapping operation will be realized by adding higher priority flows in br-int, which duplicate the ingress and/or egress packets associated with specific ports (belonging to the VMs being monitored) and send the copies to br-tap. Packets sent to br-tap will also be tagged with an appropriate VLAN id corresponding to the associated TaaS instance (in the initial release these VLAN ids may be reserved from highest to lowest; in later releases it should be coordinated with the Neutron service). The original packets will continue to be processed normally, so as not to affect the traffic patterns of the VMs being monitored. Flows will be placed in br-tap to determine if the mirrored traffic should be sent to br-tun or not. If the destination port of a Tap-aaS instance happens to reside on the same host as a source port, packets from that source port will be returned to br-int; otherwise they will be forwarded to br-tun for delivery to a remote node. Packets arriving at br-tun from br-tap will get routed to the destination ports of appropriate TaaS instances using the same GRE or VXLAN tunnel network that is used to pass regular traffic between hosts. Separate tunnel IDs will be used to isolate different TaaS instances from one another and from the normal (non-mirrored) traffic passing through the bridge. This will ensure that proper action can be taken on the receiving end of a tunnel so that mirrored traffic is sent to br-tap instead of br-int. Special flows will be used in br-tun to automatically learn about the location of the destination ports of TaaS instances. Packets entering br-tap from br-tun will be forwarded to br-int only if the destination port of the corresponding TaaS instance resides on the same host. Finally, packets entering br-int from br-tap will be delivered to the appropriate destination port after the TaaS instance VLAN id is replaced with the VLAN id for the port.

Home-page: http://www.openstack.org/ Author: OpenStack Author-email: openstack-discuss@lists.openstack.org License: UNKNOWN Description: ================ Tap as a Service ================ Tap-as-a-Service (TaaS) is an extension to the OpenStack network service (Neutron). It provides remote port mirroring capability for tenant virtual networks. Port mirroring involves sending a copy of packets entering and/or leaving one port to another port, which is usually different from the original destinations of the packets being mirrored. This service has been primarily designed to help tenants (or the cloud administrator) debug complex virtual networks and gain visibility into their VMs, by monitoring the network traffic associated with them. TaaS honors tenant boundaries and its mirror sessions are capable of spanning across multiple compute and network nodes. It serves as an essential infrastructure component that can be utilized for supplying data to a variety of network analytics and security applications (e.g. IDS). * Free software: Apache license * API
