2021-05-13tests: move test source to vpp/testDave Wallace1-3662/+0
- Generate copyright year and version instead of using hard-coded data Type: refactor Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Change-Id: I6058f5025323b3aa483f5df4a2c4371e27b5914e
2021-04-21nat: fix multi worker scenariosKlement Sekera1-20/+105
Properly select worker from hash table in out2in direction, increase number of worker threads in MW test to 4 to test these cases. Type: fix Change-Id: I76eda5761ff497b85b031dd913a64b7fcb53b33a Signed-off-by: Klement Sekera <ksekera@cisco.com>

2021-04-06tests: remove wrappersKlement Sekera1-75/+53
Improve the code by removing another kind of wrappers. Type: improvement Change-Id: I5292ef6c1761e3c6c2edd15f2aa625dac26c3732 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2021-03-20tests: add support for worker awarenessKlement Sekera1-1/+1
VppTestCase now has vpp_worker_count property set to number of workers. This can be overriden by child classes. Also overriden by VPP_WORKER_CONFIG variable for legacy reasons. Type: improvement Change-Id: Ic328bacb9003ddf9e92815767653bd362aa7f086 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2021-03-01nat: pick outside addr based on local addrKlement Sekera1-0/+39
Use outside addresses more evenly by using local address to pick from pool of addresses. This ensures stability from POV of remote host - an internal host always gets translated using the same outside address, so it doesn't appear to be "hopping". Also, this avoids all hosts being translated using the first address, which helps avoid needless recaptchas and the like. Exact assignment depends on internal ordering of addresses - local address is used to pick an offset into internal vector. If that address cannot be used, a linear search is performed as a fallback mechanism to find a possible translation.

2021-02-24nat: Final NAT44 EI/ED split patchFilip Varga1-59/+35
This patch achieves complete separation of endpoint-dependent and endpoint-independent IPv4 NAT features. Some common stuff is also moved to NAT library. Type: refactor Change-Id: I52468b7e2b5ac28958a2baf8e2ea01787322e801 Signed-off-by: Filip Varga <fivarga@cisco.com>
2021-02-18tests: re-enable NAT44ED tests for multiworkerAndrew Yourtchenko1-1/+0
Re-enable the test for 2-worker config test Change-Id: Ie108c5d244c6704ffa152177ca77f6b6055fe38e Type: test Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2021-02-11tests: tag the tests that do not work with multi-worker configurationAndrew Yourtchenko1-0/+3
If the multi-worker default VPP configuration is triggered by setting VPP_WORKER_CONFIG="workers 2", some of the tests fail for various reasons. It's a substantial number, so this change marks all of the testsets that have this issue, such that they can be addressed later independently.

2021-01-18nat: deal with flows instead of sessionsKlement Sekera1-4/+4
This change introduces flow concept to endpoint-dependent NAT. Instead of having a session and a plethora of special cases in code for e.g. hairpinning, twice-nat and others, figure all this out and store it in flow logic. Every flow has a match and a rewrite part. This unifies all the NAT packet processing cases into one - match a flow and rewrite the packet based on that flow. It also provides a cure for hairpinning dilemma where one part of the flow is on one worker and another on a different one. These cases are also sped up by not requiring destination adress lookup every single time to be able to rewrite source nat as this is now part of flow rewrite logic.
