For this, python was chosen as a high level language +allowing rapid development with scapy_ providing the necessary tool for creating +and dissecting packets. + +Anatomy of a test case +###################### + +Python's unittest_ is used as the base framework upon which the VPP test +framework is built. A test suite in the |vtf| constists of multiple classes +derived from `VppTestCase`, which is itself derived from TestCase_. +The test class defines one or more test functions, which act as test cases. + +Function flow when running a test case is: + +1. `setUpClass `: + This function is called once for each test class, allowing a one-time test + setup to be executed. If this functions throws an exception, + none of the test functions are executed. +2. `setUp `: + The setUp function runs before each of the test functions. If this function + throws an exception other than AssertionError_ or SkipTest_, then this is + considered an error, not a test failure. +3. *test_*: + This is the guts of the test case. It should execute the test scenario + and use the various assert functions from the unittest framework to check + necessary. +4. `tearDown `: + The tearDown function is called after each test function with the purpose + of doing partial cleanup. +5. `tearDownClass `: + Method called once after running all of the test funnctions to perform + the final cleanup. + +Test temporary directory and VPP life cycle +################################################ + +Test separation is achieved by separating the test files and vpp instances. +Each test creates a temporary directory and it's name is used to create +a shared memory prefix which is used to run a VPP instance. +This way, there is no conflict between any other VPP instances running +on the box and the test VPP. Any temporary files created by the test case +are stored in this temporary test directory. + +Virtual environment +################### + +Virtualenv_ is a python module which provides a means to crate an environment +containing the dependencies required by the |vtf|, allowing a separation +from any existing system-wide packages. |vtf|'s Makefile automatically +creates a virtualenv_ inside build-root and installs the required packages +in that environment. The environment is entered whenever executing a test +via one of the make test targets. + +Naming conventions +################## + +Most unit tests do some kind of packet manipulation - sending and receiving +packets between VPP and virtual hosts connected to the VPP. Referring +to the sides, addresses, etc.. is always done as if looking from the VPP side, +thus: + +* *local_* prefix is used for the VPP side. + So e.g. `local_ip4 ` address is the IPv4 address + assigned to the VPP interface. +* *remote_* prefix is used for the virtual host side. + So e.g. `remote_mac ` address is the MAC address + assigned to the virtual host connected to the VPP. + +Packet flow in the |vtf| +######################## + +Test framework -> VPP +~~~~~~~~~~~~~~~~~~~~~ + +|vtf| doesn't send any packets to VPP directly. Traffic is instead injected +using packet-generator interfaces, represented by the `VppPGInterface` class. +Packets are written into a temporary .pcap file, which is then read by the VPP +and the packets are injected into the VPP world. + +VPP -> test framework +~~~~~~~~~~~~~~~~~~~~~ + +Similarly, VPP doesn't send any packets to |vtf| directly. Instead, packet +capture feature is used to capture and write traffic to a temporary .pcap file, +which is then read and analyzed by the |vtf|. + +Test framework objects +###################### + +The following objects provide VPP abstraction and provide a means to do +common tasks easily in the test cases. + +* `VppInterface`: abstract class representing generic VPP interface + and contains some common functionality, which is then used by derived classes +* `VppPGInterface`: class representing VPP packet-generator interface. + The interface is created/destroyed when the object is created/destroyed. +* `VppSubInterface`: VPP sub-interface abstract class, containing common + functionality for e.g. `VppDot1QSubint` and `VppDot1ADSubint` classes + +How VPP API/CLI is called +######################### + +Vpp provides python bindings in a python module called vpp-papi, which the test +framework installs in the virtual environment. A shim layer represented by +the `VppPapiProvider` class is built on top of the vpp-papi, serving these +purposes: + +1. Automatic return value checks: + After each API is called, the return value is checked against the expected + return value (by default 0, but can be overridden) and an exception + is raised if the check fails. +2. Automatic call of hooks: + + a. `before_cli ` and `before_api ` hooks + are used for debug logging and stepping through the test + b. `after_cli ` and `after_api ` hooks + are used for monitoring the vpp process for crashes +3. Simplification of API calls: + Many of the VPP APIs take a lot of parameters and by providing sane defaults + for these, the API is much easier to use in the common case and the code is + more readable. E.g. ip_add_del_route API takes ~25 parameters, of which + in the common case, only 3 are needed. + +Example: how to add a new test +############################## + +In this example, we will describe how to add a new test case which tests VPP... + +1.

Throw exception in old API if the capture does not exist, thus making it clear if the test expects packets to arrive or not. Improve performance by not doing sleeps after starting the packet generator, rather lazily deleting captures when needed. Fix wrong usage of packet.show() in various tests.

For this, python was chosen as a high level language -allowing rapid development with scapy_ providing the necessary tool for creating -and dissecting packets. - -Anatomy of a test case -###################### - -Python's unittest_ is used as the base framework upon which the VPP test -framework is built. A test suite in the |vtf| consists of multiple classes -derived from `VppTestCase`, which is itself derived from TestCase_. -The test class defines one or more test functions, which act as test cases. - -Function flow when running a test case is: - -1. `setUpClass `: - This function is called once for each test class, allowing a one-time test - setup to be executed. If this functions throws an exception, - none of the test functions are executed. -2. `setUp `: - The setUp function runs before each of the test functions. If this function - throws an exception other than AssertionError_ or SkipTest_, then this is - considered an error, not a test failure. -3. *test_*: - This is the guts of the test case. It should execute the test scenario - and use the various assert functions from the unittest framework to check - necessary. Multiple test_ methods can exist in a test case. -4. `tearDown `: - The tearDown function is called after each test function with the purpose - of doing partial cleanup. -5. `tearDownClass `: - Method called once after running all of the test functions to perform - the final cleanup. - -Logging -####### - -Each test case has a logger automatically created for it, stored in -'logger' property, based on logging_. Use the logger's standard methods -debug(), info(), error(), ... to emit log messages to the logger. - -All the log messages go always into a log file in temporary directory -(see below). - -To control the messages printed to console, specify the V= parameter. - -.. code-block:: shell - - make test # minimum verbosity - make test V=1 # moderate verbosity - make test V=2 # maximum verbosity - -Test temporary directory and VPP life cycle -########################################### - -Test separation is achieved by separating the test files and vpp instances. -Each test creates a temporary directory and it's name is used to create -a shared memory prefix which is used to run a VPP instance. -The temporary directory name contains the testcase class name for easy -reference, so for testcase named 'TestVxlan' the directory could be named -e.g. vpp-unittest-TestVxlan-UNUP3j. -This way, there is no conflict between any other VPP instances running -on the box and the test VPP. Any temporary files created by the test case -are stored in this temporary test directory. - -The test temporary directory holds the following interesting files: - -* log.txt - this contains the logger output on max verbosity -* pg*_in.pcap - last injected packet stream into VPP, named after the interface, - so for pg0, the file will be named pg0_in.pcap -* pg*_out.pcap - last capture file created by VPP for interface, similarly, - named after the interface, so for e.g. pg1, the file will be named - pg1_out.pcap -* history files - whenever the capture is restarted or a new stream is added, - the existing files are rotated and renamed, soo all the pcap files - are always saved for later debugging if needed -* core - if vpp dumps a core, it'll be stored in the temporary directory -* vpp_stdout.txt - file containing output which vpp printed to stdout -* vpp_stderr.txt - file containing output which vpp printed to stderr - -*NOTE*: existing temporary directories named vpp-unittest-* are automatically -removed when invoking 'make test*' or 'make retest*' to keep the temporary -directory clean. - -Virtual environment -################### - -Virtualenv_ is a python module which provides a means to create an environment -containing the dependencies required by the |vtf|, allowing a separation -from any existing system-wide packages. |vtf|'s Makefile automatically -creates a virtualenv_ inside build-root and installs the required packages -in that environment. The environment is entered whenever executing a test -via one of the make test targets. - -Naming conventions -################## - -Most unit tests do some kind of packet manipulation - sending and receiving -packets between VPP and virtual hosts connected to the VPP. Referring -to the sides, addresses, etc. is always done as if looking from the VPP side, -thus: - -* *local_* prefix is used for the VPP side. - So e.g. `local_ip4 ` address is the IPv4 address - assigned to the VPP interface. -* *remote_* prefix is used for the virtual host side. - So e.g. `remote_mac ` address is the MAC address - assigned to the virtual host connected to the VPP. - -Automatically generated addresses -################################# - -To send packets, one needs to typically provide some addresses, otherwise -the packets will be dropped. The interface objects in |vtf| automatically -provide addresses based on (typically) their indexes, which ensures -there are no conflicts and eases debugging by making the addressing scheme -consistent. - -The developer of a test case typically doesn't need to work with the actual -numbers, rather using the properties of the objects. The addresses typically -come in two flavors: '
' and '
n' - note the 'n' suffix. -The former address is a Python string, while the latter is translated using -socket.inet_pton to raw format in network byte order - this format is suitable -for passing as an argument to VPP APIs. - -e.g. for the IPv4 address assigned to the VPP interface: - -* local_ip4 - Local IPv4 address on VPP interface (string) -* local_ip4n - Local IPv4 address - raw, suitable as API parameter. - -These addresses need to be configured in VPP to be usable using e.g. -`config_ip4` API. Please see the documentation to `VppInterface` for more -details. - -By default, there is one remote address of each kind created for L3: -remote_ip4 and remote_ip6. If the test needs more addresses, because it's -simulating more remote hosts, they can be generated using -`generate_remote_hosts` API and the entries for them inserted into the ARP -table using `configure_ipv4_neighbors` API. - -Packet flow in the |vtf| -######################## - -Test framework -> VPP -~~~~~~~~~~~~~~~~~~~~~ - -|vtf| doesn't send any packets to VPP directly. Traffic is instead injected -using packet-generator interfaces, represented by the `VppPGInterface` class. -Packets are written into a temporary .pcap file, which is then read by the VPP -and the packets are injected into the VPP world. - -To add a list of packets to an interface, call the `add_stream` method on that -interface. Once everything is prepared, call `pg_start` method to start -the packet generator on the VPP side. - -VPP -> test framework -~~~~~~~~~~~~~~~~~~~~~ - -Similarly, VPP doesn't send any packets to |vtf| directly. Instead, packet -capture feature is used to capture and write traffic to a temporary .pcap file, -which is then read and analyzed by the |vtf|. - -The following APIs are available to the test case for reading pcap files. - -* `get_capture`: this API is suitable for bulk & batch style of test, where - a list of packets is prepared & sent, then the received packets are read - and verified. The API needs the number of packets which are expected to - be captured (ignoring filtered packets - see below) to know when the pcap - file is completely written by the VPP. If using packet infos for verifying - packets, then the counts of the packet infos can be automatically used - by `get_capture` to get the proper count (in this case the default value - None can be supplied as expected_count or ommitted altogether). -* `wait_for_packet`: this API is suitable for interactive style of test, - e.g. when doing session management, three-way handsakes, etc. This API waits - for and returns a single packet, keeping the capture file in place - and remembering context. Repeated invocations return following packets - (or raise Exception if timeout is reached) from the same capture file - (= packets arriving on the same interface). - -*NOTE*: it is not recommended to mix these APIs unless you understand how they -work internally. None of these APIs rotate the pcap capture file, so calling -e.g. `get_capture` after `wait_for_packet` will return already read packets. -It is safe to switch from one API to another after calling `enable_capture` -as that API rotates the capture file. - -Automatic filtering of packets: -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Both APIs (`get_capture` and `wait_for_packet`) by default filter the packet -capture, removing known uninteresting packets from it - these are IPv6 Router -Advertisments and IPv6 Router Alerts. These packets are unsolicitated -and from the point of |vtf| are random. If a test wants to receive these -packets, it should specify either None or a custom filtering function -as the value to the 'filter_out_fn' argument. - -Common API flow for sending/receiving packets: -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -We will describe a simple scenario, where packets are sent from pg0 to pg1 -interface, assuming that the interfaces were created using -`create_pg_interfaces` API. - -1. Create a list of packets for pg0:: - - packet_count = 10 - packets = create_packets(src=self.pg0, dst=self.pg1, - count=packet_count) - -2. Add that list of packets to the source interface:: - - self.pg0.add_stream(packets) - -3. Enable capture on the destination interface:: - - self.pg1.enable_capture() - -4. Start the packet generator:: - - self.pg_start() - -5. Wait for capture file to appear and read it:: - - capture = self.pg1.get_capture(expected_count=packet_count) - -6. Verify packets match sent packets:: - - self.verify_capture(send=packets, captured=capture) - -Test framework objects -###################### - -The following objects provide VPP abstraction and provide a means to do -common tasks easily in the test cases. - -* `VppInterface`: abstract class representing generic VPP interface - and contains some common functionality, which is then used by derived classes -* `VppPGInterface`: class representing VPP packet-generator interface. - The interface is created/destroyed when the object is created/destroyed. -* `VppSubInterface`: VPP sub-interface abstract class, containing common - functionality for e.g. `VppDot1QSubint` and `VppDot1ADSubint` classes - -How VPP APIs/CLIs are called -############################ - -Vpp provides python bindings in a python module called vpp-papi, which the test -framework installs in the virtual environment. A shim layer represented by -the `VppPapiProvider` class is built on top of the vpp-papi, serving these -purposes: - -1. Automatic return value checks: - After each API is called, the return value is checked against the expected - return value (by default 0, but can be overridden) and an exception - is raised if the check fails. -2. Automatic call of hooks: - - a. `before_cli ` and `before_api ` hooks - are used for debug logging and stepping through the test - b. `after_cli ` and `after_api ` hooks - are used for monitoring the vpp process for crashes -3. Simplification of API calls: - Many of the VPP APIs take a lot of parameters and by providing sane defaults - for these, the API is much easier to use in the common case and the code is - more readable. E.g. ip_add_del_route API takes ~25 parameters, of which - in the common case, only 3 are needed. - -Utility methods -############### - -Some interesting utility methods are: - -* `ppp`: 'Pretty Print Packet' - returns a string containing the same output - as Scapy's packet.show() would print -* `ppc`: 'Pretty Print Capture' - returns a string containing printout of - a capture (with configurable limit on the number of packets printed from it) - using `ppp` - -*NOTE*: Do not use Scapy's packet.show() in the tests, because it prints -the output to stdout. All output should go to the logger associated with -the test case. - -Example: how to add a new test -############################## - -In this example, we will describe how to add a new test case which tests -basic IPv4 forwarding. - -1. Add a new file called test_ip4_fwd.py in the test directory, starting - with a few imports:: - - from framework import VppTestCase - from scapy.layers.l2 import Ether - from scapy.packet import Raw - from scapy.layers.inet import IP, UDP - from random import randint - -2.

If this functions throws an exception, + none of the test functions are executed. +2. `setUp `: + The setUp function runs before each of the test functions. If this function + throws an exception other than AssertionError_ or SkipTest_, then this is + considered an error, not a test failure. +3. *test_*: + This is the guts of the test case. It should execute the test scenario + and use the various assert functions from the unittest framework to check + necessary. Multiple test_ methods can exist in a test case. +4. `tearDown `: + The tearDown function is called after each test function with the purpose + of doing partial cleanup. +5. `tearDownClass `: + Method called once after running all of the test functions to perform + the final cleanup. + +Logging +####### + +Each test case has a logger automatically created for it, stored in +'logger' property, based on logging_. Use the logger's standard methods +debug(), info(), error(), ... to emit log messages to the logger. + +All the log messages go always into a log file in temporary directory +(see below). + +To control the messages printed to console, specify the V= parameter. + +.. code-block:: shell + + make test # minimum verbosity + make test V=1 # moderate verbosity + make test V=2 # maximum verbosity + +Test temporary directory and VPP life cycle +########################################### + +Test separation is achieved by separating the test files and vpp instances. +Each test creates a temporary directory and it's name is used to create +a shared memory prefix which is used to run a VPP instance. +The temporary directory name contains the testcase class name for easy +reference, so for testcase named 'TestVxlan' the directory could be named +e.g. vpp-unittest-TestVxlan-UNUP3j. +This way, there is no conflict between any other VPP instances running +on the box and the test VPP. Any temporary files created by the test case +are stored in this temporary test directory. + +The test temporary directory holds the following interesting files: + +* log.txt - this contains the logger output on max verbosity +* pg*_in.pcap - last injected packet stream into VPP, named after the interface, + so for pg0, the file will be named pg0_in.pcap +* pg*_out.pcap - last capture file created by VPP for interface, similarly, + named after the interface, so for e.g. pg1, the file will be named + pg1_out.pcap +* history files - whenever the capture is restarted or a new stream is added, + the existing files are rotated and renamed, soo all the pcap files + are always saved for later debugging if needed +* core - if vpp dumps a core, it'll be stored in the temporary directory +* vpp_stdout.txt - file containing output which vpp printed to stdout +* vpp_stderr.txt - file containing output which vpp printed to stderr + +*NOTE*: existing temporary directories named vpp-unittest-* are automatically +removed when invoking 'make test*' or 'make retest*' to keep the temporary +directory clean. + +Virtual environment +################### + +Virtualenv_ is a python module which provides a means to create an environment +containing the dependencies required by the |vtf|, allowing a separation +from any existing system-wide packages. |vtf|'s Makefile automatically +creates a virtualenv_ inside build-root and installs the required packages +in that environment. The environment is entered whenever executing a test +via one of the make test targets. + +Naming conventions +################## + +Most unit tests do some kind of packet manipulation - sending and receiving +packets between VPP and virtual hosts connected to the VPP. Referring +to the sides, addresses, etc. is always done as if looking from the VPP side, +thus: + +* *local_* prefix is used for the VPP side. + So e.g. `local_ip4 ` address is the IPv4 address + assigned to the VPP interface. +* *remote_* prefix is used for the virtual host side. + So e.g. `remote_mac ` address is the MAC address + assigned to the virtual host connected to the VPP. + +Automatically generated addresses +################################# + +To send packets, one needs to typically provide some addresses, otherwise +the packets will be dropped. The interface objects in |vtf| automatically +provide addresses based on (typically) their indexes, which ensures +there are no conflicts and eases debugging by making the addressing scheme +consistent. + +The developer of a test case typically doesn't need to work with the actual +numbers, rather using the properties of the objects. The addresses typically +come in two flavors: '
' and '
n' - note the 'n' suffix. +The former address is a Python string, while the latter is translated using +socket.inet_pton to raw format in network byte order - this format is suitable +for passing as an argument to VPP APIs. + +e.g. for the IPv4 address assigned to the VPP interface: + +* local_ip4 - Local IPv4 address on VPP interface (string) +* local_ip4n - Local IPv4 address - raw, suitable as API parameter. + +These addresses need to be configured in VPP to be usable using e.g. +`config_ip4` API. Please see the documentation to `VppInterface` for more +details. + +By default, there is one remote address of each kind created for L3: +remote_ip4 and remote_ip6. If the test needs more addresses, because it's +simulating more remote hosts, they can be generated using +`generate_remote_hosts` API and the entries for them inserted into the ARP +table using `configure_ipv4_neighbors` API. + +Packet flow in the |vtf| +######################## + +Test framework -> VPP +~~~~~~~~~~~~~~~~~~~~~ + +|vtf| doesn't send any packets to VPP directly. Traffic is instead injected +using packet-generator interfaces, represented by the `VppPGInterface` class. +Packets are written into a temporary .pcap file, which is then read by the VPP +and the packets are injected into the VPP world. + +To add a list of packets to an interface, call the `add_stream` method on that +interface. Once everything is prepared, call `pg_start` method to start +the packet generator on the VPP side. + +VPP -> test framework +~~~~~~~~~~~~~~~~~~~~~ + +Similarly, VPP doesn't send any packets to |vtf| directly. Instead, packet +capture feature is used to capture and write traffic to a temporary .pcap file, +which is then read and analyzed by the |vtf|. + +The following APIs are available to the test case for reading pcap files. + +* `get_capture`: this API is suitable for bulk & batch style of test, where + a list of packets is prepared & sent, then the received packets are read + and verified. The API needs the number of packets which are expected to + be captured (ignoring filtered packets - see below) to know when the pcap + file is completely written by the VPP. If using packet infos for verifying + packets, then the counts of the packet infos can be automatically used + by `get_capture` to get the proper count (in this case the default value + None can be supplied as expected_count or ommitted altogether). +* `wait_for_packet`: this API is suitable for interactive style of test, + e.g. when doing session management, three-way handsakes, etc. This API waits + for and returns a single packet, keeping the capture file in place + and remembering context. Repeated invocations return following packets + (or raise Exception if timeout is reached) from the same capture file + (= packets arriving on the same interface). + +*NOTE*: it is not recommended to mix these APIs unless you understand how they +work internally. None of these APIs rotate the pcap capture file, so calling +e.g. `get_capture` after `wait_for_packet` will return already read packets. +It is safe to switch from one API to another after calling `enable_capture` +as that API rotates the capture file. + +Automatic filtering of packets: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Both APIs (`get_capture` and `wait_for_packet`) by default filter the packet +capture, removing known uninteresting packets from it - these are IPv6 Router +Advertisments and IPv6 Router Alerts. These packets are unsolicitated +and from the point of |vtf| are random. If a test wants to receive these +packets, it should specify either None or a custom filtering function +as the value to the 'filter_out_fn' argument. + +Common API flow for sending/receiving packets: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +We will describe a simple scenario, where packets are sent from pg0 to pg1 +interface, assuming that the interfaces were created using +`create_pg_interfaces` API. + +1. Create a list of packets for pg0:: + + packet_count = 10 + packets = create_packets(src=self.pg0, dst=self.pg1, + count=packet_count) + +2. Add that list of packets to the source interface:: + + self.pg0.add_stream(packets) + +3. Enable capture on the destination interface:: + + self.pg1.enable_capture() + +4. Start the packet generator:: + + self.pg_start() + +5. Wait for capture file to appear and read it:: + + capture = self.pg1.get_capture(expected_count=packet_count) + +6. Verify packets match sent packets:: + + self.verify_capture(send=packets, captured=capture) + +Test framework objects +###################### + +The following objects provide VPP abstraction and provide a means to do +common tasks easily in the test cases. + +* `VppInterface`: abstract class representing generic VPP interface + and contains some common functionality, which is then used by derived classes +* `VppPGInterface`: class representing VPP packet-generator interface. + The interface is created/destroyed when the object is created/destroyed. +* `VppSubInterface`: VPP sub-interface abstract class, containing common + functionality for e.g. `VppDot1QSubint` and `VppDot1ADSubint` classes + +How VPP APIs/CLIs are called +############################ + +Vpp provides python bindings in a python module called vpp-papi, which the test +framework installs in the virtual environment. A shim layer represented by +the `VppPapiProvider` class is built on top of the vpp-papi, serving these +purposes: + +1. Automatic return value checks: + After each API is called, the return value is checked against the expected + return value (by default 0, but can be overridden) and an exception + is raised if the check fails. +2. Automatic call of hooks: + + a. `before_cli ` and `before_api ` hooks + are used for debug logging and stepping through the test + b. `after_cli ` and `after_api ` hooks + are used for monitoring the vpp process for crashes +3. Simplification of API calls: + Many of the VPP APIs take a lot of parameters and by providing sane defaults + for these, the API is much easier to use in the common case and the code is + more readable. E.g. ip_add_del_route API takes ~25 parameters, of which + in the common case, only 3 are needed. + +Utility methods +############### + +Some interesting utility methods are: + +* `ppp`: 'Pretty Print Packet' - returns a string containing the same output + as Scapy's packet.show() would print +* `ppc`: 'Pretty Print Capture' - returns a string containing printout of + a capture (with configurable limit on the number of packets printed from it) + using `ppp` + +*NOTE*: Do not use Scapy's packet.show() in the tests, because it prints +the output to stdout. All output should go to the logger associated with +the test case. + +Example: how to add a new test +############################## + +In this example, we will describe how to add a new test case which tests +basic IPv4 forwarding. + +1.

The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests.

The common code is the same: vpp = VPP(...) vpp.connect(...) Calling VPP API is different, instead of deprecated: vpp.show_version() # deprecated one should write vpp.api.show_version() this allows VPP messages like "connect" and "disconnect" to be used, once the old API is dropped (in 17.07). Also part of this patch is a check for name conflict, to prevent VPP object overwriting its own functionality with generated code based on json files.

This allows the 'emulation' of bridging. That is hosts in one sub-net reachable via differenet interfaces. Introducate a new API command: ip6 nd proxy this indicates 2 things; 1) that host is reachable out of interface . VPP will thus install that route. 2) NS requests sent to will be responeded to (i.e. proxied).

In promiscuous mode, L3 interface need to verify DMAC of packet to match that of the interface and drop if not. This check was done on sub-interface only and now also added to main interface path. Fix incorrect MAC addresses in the flow-per-pkt plugin test, which caused it to fail. Fix MAC address usage in BFD tests.

This allows to change the behavior to permit the fragmented packets for the default "permit specific rules" ruleset, but also gives the flexibility to block the non-initial fragments by inserting into the begining a bogus rule which would deny the L4 traffic. Also, add a knob which allows to potentially turn this behavior off in case of a dire need (and revert to dropping all non-initial fragments), via a debug CLI.

Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

the flow hash config is (and was) cached on the load-balance object so the fib_table_t struct is not used a switch time. Therefore changes to the table's flow hash config need to be propagated to all load-balances and hance all FIB entries in the table. - enable API for setting the IPv6 table flow hash config - use only the hash config in the fib_table_t object and not on the ipX_fib_t - add tests.

lookup Add a bihash-based ACL lookup mechanism and make it a new default. This changes the time required to lookup a 5-tuple match from O(total_N_entries) to O(total_N_mask_types), where "mask type" is an overall mask on the 5-tuple required to represent an ACE. For testing/comparison there is a temporary debug CLI "set acl-plugin use-hash-acl-matching {0|1}", which, when set to 0, makes the plugin use the "old" linear lookup, and when set to 1, makes it use the hash-based lookup. Based on the discussions on vpp-dev mailing list, prevent assigning the ACL index to an interface, when the ACL with that index is not defined, also prevent deleting an ACL if that ACL is applied. Also, for the easier debugging of the state, there are new debug CLI commands to see the ACL plugin state at several layers: "show acl-plugin acl [index N]" - show a high-level ACL representation, used for the linear lookup and as a base for building the hashtable-based lookup. Also shows if a given ACL is applied somewhere. "show acl-plugin interface [sw_if_index N]" - show which interfaces have which ACL(s) applied. "show acl-plugin tables" - a lower-level debug command used to see the state of all of the related data structures at once. There are specifiers possible, which make for a more focused and maybe augmented output: "show acl-plugin tables acl [index N]" show the "bitmask-ready" representations of the ACLs, we well as the mask types and their associated indices. "show acl-plutin tables mask" show the derived mask types and their indices only. "show acl-plugin tables applied [sw_if_index N]" show the table of all of the ACEs applied for a given sw_if_index or all interfaces. "show acl-plugin tables hash [verbose N]" show the 48x8 bihash used for the ACL lookup.

treated as transient (VPP-932) The packet that was creating the session was not tracked, consequently the TCP flags seen within the session record never got the value for the session to get treated as being in the established state. Test-escape, so add the TCP tests which test the three phases of the TCP session life and make them all pass.

Date: Tue, 15 Aug 2017 05:33:11 -0700 Subject: Support proxy ARP on mirrored TAP interfaces When VPP has an interface whose address is also applied to a TAP interface on the host, then VPP's TAP interface will be unnumbered to the 'real' interface and do proxy ARP from the host. the curious aspect of this setup is that ARP requests from the host will come from the VPP's own address.

This is a simple wrapper around a sw_if_index. enhance DPO stacking functions to allow per-instance next-nodes and hence allow children to stack onto the interface per-instance tx node and not on 'interface-output'. 2) update PPPoE code to use ta midchain stack on a interface-tx DPO of the encap-interface. This remove the need for pppoe_encap node (which is replaced by the adj-midchain-tx) and interface-output node is no longer used (see above). Since PPPoE encap node is no longer needed, the PPPoE seesion does not need to be retrieved in the data-path, hence the cahce misses are removed.
