Add new UPG E2E tests (travelping#23)
* e2e: quick and dirty prototype of 'captive VPP' * e2e: use http.Client for downloading * e2e: add framework package * e2e: copy netns stuff from CNI plugins * e2e: refactor netns usage a bit * e2e: add hs_proxy based test and remove main.go for now * e2e: make VPP config more flexible * e2e: add basic PFCP Association test * e2e: store PCAPs * e2e: establish PFCP session * e2e: update base image name * e2e: add names for namespaces * e2e: add routes * e2e: add ping to the image * e2e: download some data through UPG * e2e: disable offload for veths This gives a substantial speed boost so we also increase download size * e2e: disable http_static use for now as it breaks on Mac Docker * e2e: use gopacket instead of tcpdump to capture the packets * e2e: use patched go-pfcp from github * e2e: fix method name * e2e: improve docker env Specify base image as a build arg. Also, use dumb-init to avoid having zombies. * e2e: add README.md * e2e: reduce noise from NetNS.disableOffloading() * e2e: improve TrafficGen config and skip VPP WS test on Mac Docker * e2e: issue SessionModificationRequests with QueryURR and handle responses * e2e: refactor PFCPConnection * e2e: reproduce the crash on bad pdr_idx in the frame * e2e: fail when VPP dies * e2e: add a separate test case for PDR replacement crash * e2e: use saner PFCPConnection interface that suports multiple sessions * e2e: add PDR replacement test Crashes UPG if `idBase ^= 9` is uncommented * e2e: fix stopping upon VPP crash * e2e: fix traffic volume checks * e2e: make VPP binary and plugin paths configurable This helps with running the tests against VPP built using its 'make' * e2e: add UDP test cases * e2e: do actually change PDR Ids in TestPDRReplacement * e2e: remove obsolete comments * e2e: test app detection * e2e: test switching proxy on/off * e2e: refactor and add UPG_TEST_QUICK env var * e2e: add redirect test * e2e: switch to Ginkgo/Gomega * e2e: switch to govpp master to avoid panics upon VPP crash * e2e: update README.md after switching to Ginkgo/Gomega * e2e: add PGW mode * e2e: make PGW tests pass and enable PDR replacement for PGW * e2e: port newer uplane changes from sgwsimulator This fixes some of the unneeded error logging (that wasn't causing any test failures, though). * e2e: fix handling GTPU issues * e2e: fix silly sleep * e2e: fix kernel GTPU and re-do GTPU close fix Some of the things need to be done inside the respective network namespaces. Previous "GTPU issues" fix was a red herring, what we really have here is net conn's File() method breaking things after Fd() is retrieved from it. Ref: golang/go#29277 https://github.com/golang/go/blob/2291cae2af659876e93a3e1f95c708abb1475d02/src/os/file_unix.go#L76-L80 * e2e: add IPv6 tests * e2e: fix logging * e2e: fix SEID logging * e2e: add extra checks to ensure proper netns for Dial/Listen * e2e: support running tests in parallel * e2e: split framework package * e2e: add conn flood (+netem) tests * e2e: relax UDP content checks when retries are enabled * e2e: add icmp ping test * e2e: add session deletion loop and fix conn flood test * e2e: add MTU test * e2e: add artifacts dir * e2e: add junit reporting * Integrate new e2e tests with the rest of UPG * e2e: fix ICMP test name * e2e: make tests lighter (especially http) * e2e: use Ginkgo --flakeAttempts (mis)feature to cope with flakes Apparently, CI environment is not powerful enough to handle the tests atm. * e2e: fix http trafficgen flakes in persist mode * e2e: fix excessive resource consumption Had to tune down 'excessive' tests for now. Eventually, need to update trafficgen routines so that they don't allocate a new buffer for each goroutine. * e2e: fix compat with earlier UPF builds * e2e: try using 8 parallel nodes for e2e * e2e: add minimal docs * e2e: use Tomb for easier goroutine lifecycle control
