Nightly Test Tesults

Libreswan's testsuite is run nightly. The results are published here, with the most recent result here. The tests are categorized as:

  • good: these tests are expected to pass (unfortunately, some still have timing problems and occasionally fail)
  • wip: these tests require further work, for instance the result may not be deterministic, or the bug they demonstrate hasn't yet been fixed
  • skiptest: these tests require manual intervention to run

To run tests locally, read on.

Running tests

The libreswan tests, in testing/pluto, can be run using several different mechanisms:

Test Frameworks
Framework Speed Host OS Guest OS initsystem testing (systemd, rc.d, ...) Post-mortem Interop testing Notes
KVM slower Fedora, Debian
(BSD anyone?)
Alpine, Fedora, FreeBSD, NetBSD, OpenBSD, Debian yes shutdown, core, leaks, refcnt, selinux strongswan (Linux, FreeBSD), iked (OpenBSD), racoon (NetBSD), racoon2 (NetBSD) gold standard
ideal for BSD builds
idea for testing custom kernels
used by the Testing machine
requires 9p (virtio anyone?)
Namespaces fast linux uses host's libreswan, kernel, and utilities no core, leaks strongswan (linux)? ideal for quick tests
requires libreswan to be built/installed on the host
requires all dependencies to be installed on the host
test results sensitive differing kernel and utilities
Docker linux uses host's kernel
uses distro's utilities
? ? ? ideal for cross-linux builds (CentOS 6, 7, 8, Fedora 28 - rawhide, Debian, Ubuntu)
sensitive to differing kernel and utilities

How tests work

All the test cases involving VMs are located in the libreswan directory under testing/pluto/. The most basic test case is called basic-pluto-01. Each test case consists of a few files:

  • description.txt to explain what this test case actually tests
  • ipsec.conf files - for host west is called west.conf. This can also include configuration files for strongswan or racoon2 for interop testig
  • ipsec.secret files - if non-default configurations are used. also uses the host syntax, eg west.secrets, east.secrets.
  • An init.sh file for each VM that needs to start (eg westinit.sh, eastinit.sh, etc)
  • One run.sh file for the host that is the initiator (eg westrun.sh)
  • Known good (sanitized) output for each VM (eg west.console.txt, east.console.txt)
  • testparams.sh if there are any non-default test parameters

Once the test run has completed, you will see an OUTPUT/ directory in the test case directory:

$ ls OUTPUT/
east.console.diff  east.console.verbose.txt  RESULT       west.console.txt          west.pluto.log
east.console.txt   east.pluto.log            swan12.pcap  west.console.diff  west.console.verbose.txt
  • RESULT is a text file (whose format is sure to change in the next few months) stating whether the test succeeded or failed.
  • The diff files show the differences between this testrun and the last known good output.
  • Each VM's serial (sanitized) console log (eg west.console.txt)
  • Each VM's unsanitized verbose console output (eg west.console.verbose.txt)
  • A network capture from the bridge device (eg swan12.pcap)
  • Each VM's pluto log, created with plutodebug=all (eg west.pluto.log)
  • Any core dumps generated if a pluto daemon crashed
testing/baseconfigs/
configuration files installed on guest machines
testing/guestbin/
shell scripts used by tests, and run on the guest
testing/linux-system-roles.vpn/
???
testing/packaging/
???
testing/pluto/TESTLIST
list of tests, and their expected outcome
testing/pluto/*/
individual test directories
testing/programs/
executables used by tests, and run on the guest
testing/sanitizers/
filters for cleaning up the test output
testing/utils/
test drivers and other host tools
testing/x509/
certificates, scripts are run on a guest

Network Diagrams

Current Network Diagram

  • interface-0 (eth0, vio0, vioif0) is connected to SWANDEFAULT which has a NAT gateway to the internet
    • the exceptions are the Fedora test domains: EAST, WEST, ROAD, NORTH; should they?
    • the BSD domains always up inteface-0 so that /pool, /source, and /testing can be NFS mounted
    • NIC needs to run DHCP on eth0 manually; how?
    • transmogrify does not try to modify interface-0(SWANDEFAULT) (it breaks established network sessions such as NFS)
  • the interface names do not have consistent order (see comment above about Fedora's interface-0 not pointing at SWANDEFAULT)
    • Fedora has ethN
    • OpenBSD has vioN (different order)
    • NetBSD has vioifN (different order)
