Running tests

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

Test Frameworks
Framework Speed Host Guest Modifies / Notes
Namespaces fast linux linux yes results are host dependent (for instance the host's kernel version)
requires all dependencies, including libreswan, to be installed on /
no systemd tests
KVM slower generic? Fedora, FreeBSD, NetBSD, OpenBSD no in theory it can be run on any system supporting libvirt/KVM (but only Linux has ever been used)
Docker linux Linux centric using host kernel.
Ideal for build tests.
Can build using various Linux Distributions : CentOS 6, 7, 8, Fedora 28 - rawhide, Debian, Ubuntu.
Also for run tests using systemd.

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

Network Diagrams

Fine Print

  • 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)
