* tests: Prepare distro images during asset build phaseDavid Gibson2022-07-141-22/+3
| | | | | | | | | | | | | | | | | | | | | | | Before booting the guest images, the distro test cases need to modify the guest images, using virt-edit and guestfish, to boot in the way we need. At present this gets repeated on every test run, even though it's not really doing anything we want to test for. In addition many of the images have the same preparation steps leading to a lot of duplicated stages in the tests. A number of additional images can be prepared using common steps, even if the ones used now have small differences. Therefore move the preparation of most of the guest images to the asset build phase, where they can be done a single time for multiple test runs, using a common preparation script. We can even avoid making a copy of the disk image for booting, by using qemu's -snapshot option. A few of the distros (openSUSE and older Ubuntu) do need different steps. For now we don't chage how they are run, they could possibly be handled more like this in future. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Move distro image download to asset build makefileDavid Gibson2022-07-141-7/+7
| | | | | | | | | | | | Rather than directly download distro images from the test scripts, handle all the downloads during the test asset build, then just clone them for the tests themselves. This avoids repeated downloads which can be very slow when debugging failing tests.

* Invoke specific qemu-system-* binariesDavid Gibson2022-07-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | A lot of tests and examples invoke qemu with the command "kvm". However, as far as I can tell, "kvm" being aliased to the appropriate qemu system binary is Debian specific. The binary names from qemu upstream - qemu-system-$ARCH - also aren't universal, but they are more common (they should be good for both Debian and Fedora at least). In order to still get KVM acceleration when available, we use the option "-M accel=kvm:tcg" to tell qemu to try using either KVM or TCG in that order A number of the places we invoked "kvm" are expecting specifically an x86 guest, and so it's also safer to explicitly invoke qemu-system-x86_64. Some others appear to be independent of the target arch (just wanting the same arch as the host to allow KVM acceleration). Although I suspect there may be more subtle x86 specific options in the qemu command lines, attempt to preserve arch independence by using $(uname -m).

* tests: qemu-system-ppc64le isn't a thingDavid Gibson2022-07-141-2/+2
| | | | | | | | | | | | Several tests run pp64le guests using "qemu-system-ppc64le". But, at the system level there's no difference between ppc64 and ppc64le - it's the same hardware, just placed into different endian modes by OS early boot code. Reflecting that, qemu only supplies a single "qemu-system-ppc64". Some distros alias qemu-system-ppc64le to qemu-system-ppc64 (Debian does), but it's best not to count on this (Fedora doesn't, for example). Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Makefile: Use $(BIN) and $(MANPAGES) variable to simplify several targetsDavid Gibson2022-06-181-1/+1
| | | | | | | | | | | | | | There are several places which explicitly list the various generated binaries, even though a $(BIN) variable already lists them. There are several more places that list all the manpage files, introduce a $(MANPAGES) variable to remove that repetition as well. Tweak the generation of pasta.1 as a link to passt.1 so it's not just made as a side effect of the pasta target.

* Tweak dhclient arguments for readabilityDavid Gibson2022-06-151-2/+2
| | | | | | | | | | | | | | A number of tests and examples use dhclient in both IPv4 and IPv6 modes. We use "dhclient -6" for IPv6, but usually just "dhclient" for IPv4. Add an explicit "-4" argument to make it more clear and explicit. In addition, when dhclient is run from within pasta it usually won't be "real" root, and so will not have access to write the default global pid file. This results in a mostly harmless but irritating error: Can't create /var/run/dhclient.pid: Permission denied We can avoid that by using the --no-pid flag to dhclient.

* tests: Simplify explicit checks for command successDavid Gibson2022-05-191-10/+5
| | | | | | | | | A number of individual test cases use '*out' commands to check for success of specific commands they've issued. Now that the test harness is testing for success of all issued commands as a matter of course, we no longer need to do this. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test/distro/ubuntu: Use DEBIAN_FRONTEND=noninteractive for apt on 22.04Stefano Brivio2022-02-211-0/+1
| | | | | | | | | Removing the needrestart package doesn't seem to work anymore, and I'm getting again prompts to restart services after installing gcc and make: export DEBIAN_FRONTEND=noninteractive before installing packages to avoid that. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test/distro/ubuntu: Skip apt-get update for 16.04 on powerpcStefano Brivio2022-01-301-1/+3
| | | | | | | | Some recent change to xenial-updates broke dependencies for gcc, it can't be installed anymore. Skipping apt-get update leaves gcc dependencies in a consistent state, though. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test/distro: Avoid race between display of ns_msg and netcat exitingStefano Brivio2022-01-301-0/+1
| | | | | | | | | The shell might report 'nc -6 -l -p 9999 > /tmp/ns_msg' as done even after the subsequent 'echo' is done: wait one second before reading out /tmp/ns_msg, to ensure we read that instead of the "Done" message. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test: Add distribution tests for several architectures and kernel versionsStefano Brivio2022-01-281-0/+208
The new tests check build and a simple case with pasta sending a short message in both directions (namespace to init, init to namespace). Tests cover a mix of Debian, Fedora, OpenSUSE and Ubuntu combinations on aarch64, i386, ppc64, ppc64le, s390x, x86_64. Builds tested starting from approximately glibc 2.19, gcc 4.7, and actual functionality approximately from 4.4 kernels, glibc 2.25, gcc 4.8, all the way up to current glibc/gcc/kernel versions.
