2017-11-01VPP Object Model (VOM)Neale Ranns1-0/+30
The VOM is a C++ library for use by clients/agents of VPP for programming state. It uses the binary APIs to do so. Various other common client side functions are also provided. Please see om.hpp for a more detailed description.

2017-09-29make test: fix/disable VAPI tests on centosKlement Sekera1-0/+9
Workaround old `check' library on centos. Disable building/running of C++ VAPI test as centos's gcc can't compile our C++ code (vapi.hpp) due to bug. Change-Id: If9da9c7f1bc076f7cdfb9bd3016dfe60a08afa36 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2017-08-17make test: collect symlinks to failed testsKlement Sekera1-1/+21
Compress files in temporary directories of failed tests and symlink the directories under /tmp/vpp-failed-unittests location - preparation for jenkins archivation. Automatically cleanup the directory at start of test run. The compression is performed only when environment variable COMPRESS_FAILED_TEST_LOGS is set to one of "yes", "y", "1". This is set in verify target, but left unset by default, so when invoking make test by hand, files won't be compressed.

2017-08-10make test: detect hung testsKlement Sekera1-2/+40
Run tests in a forked process with a set of pipes to communicate keep-alives and overall result. This allows us to detect when e.g. vpp dies mid-API call causing the test to hang waiting for response (which will never come since vpp died). Support setting a (per test case) TIMEOUT make test option to set timeout, with a default timeout of 120 seconds. Example - fail the test suite if any test-case fails to finish within 300s: make TIMEOUT=300 test Change-Id: I0d04f26a7232968f4bf043adf5d5b508f5018717 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2017-04-10make test: automatic "vpp finishes startup" checkKlement Sekera1-13/+28
Add code which checks if vpp doesn't crash/exit immediately after startup to aid debugging stuff like mistyped graph node name or so. Refuse to run tests if the vpp is unable to start, complain loudly and print vpp's stderr at critical log level if this happens to make spotting these problems in jenkins easy.

2017-04-06BFD-FIB interactionsNeale Ranns1-1/+1
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

2017-03-08make test: split into basic and extended testsKlement Sekera1-3/+27
Implement plumbing to allow decorating tests as extended, e.g.: @unittest.skipUnless(running_extended_tests(), "part of extended tests") both methods and classes can be decorated this way. Change make test and make test-debug to run only non-extended tests. Introduce make test-all and make test-all-debug to run the full suite. Run full suite as part of make verify. Decorate most BFD tests as extended. Change-Id: I3bc64f59e9fe238f7f767d7e043dc165d03e9dfa Signed-off-by: Klement Sekera <ksekera@cisco.com>

2017-02-09make test: work around scapy truncated packetsKlement Sekera1-0/+32
Under stress, it's possible to hit a race condition, when the packet header is fully written to pcap, but not all packet data - yet. Scapy is stupid enough to: 1. not detect and report this error, truncating the packet instead 2. continue munching more data from wrong offset The work around is to scan the file ahead, parse the packet header, figure out how much data we need, wait for the file to be big enough, then restore the file position back to where it was and finally let scapy parse the packet.

Add authentication support to BFD feature. Out of three existing authentication types, implement SHA1 (sole RFC requirement). Simple password is insecure and MD5 is discouraged by the RFC, so ignore those. Add/change APIs to allow configuring BFD authentication keys and their usage with BFD sessions.

2016-12-23make test: improve handling of packet capturesKlement Sekera1-21/+32
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2016-12-16make test: improve robustness and performanceKlement Sekera1-11/+30
Introduce an API which asserts empty capture for interface. 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.
