* test: Convert distro tests to use socat instead of nc/ncatDavid Gibson2022-08-201-14/+14
| | | | | | | | | | | | | | | | | We've recently converted most of our tests to use socat instead of nc/netcat/ncat, because socat is more powerful and we don't need to deal with the several possible variants of netcat. We still use nc or ncat for the distro tests. Because there we control the guest environment and can pick our tools, there isn't the same reason to switch to socat. However, using socat here as well makes the tests a bit easier to read, and doesn't require people reading or modifying them to become familiar with an additional tool.

* test: Expand root partition of Debian sid amd64 and aarch64 imagesStefano Brivio2022-07-291-0/+12
| | | | | | | | | | | | | | | A couple of days ago, we started running out of space there as we're about to install gcc -- about 50 MiB are missing. Given that virt-resize (which could be conveniently invoked by the Makefile for tests) reorders partitions if we expand the first one, resize the image using qemu-img from the test script itself, and then take care of expanding root partition and filesystem online later. This is probably a temporary hack, so I'm not looking for a more generic or elegant solution at the moment. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* tests: Remove unused DNS6 calculation from fedora testsDavid Gibson2022-07-141-1/+1
| | | | | | | | | | | | | | | | | | The Fedora test file extracts some information from the host resolv.conf into a DNS6 variable which is then never used. Remove this unnecessary step, which is presumably a leftover from an earlier iteration. This was the only user of 'head' and 'sed' in the test file, so those can also be removed from the required tools. The debian and ubuntu test files also listed 'head' and 'sed' as tools, although they don't use them, I'm guessing because of an earlier version which had the same DNS6 code. Remove those as well. The opensuse test file still actually uses DNS6, so leave it there for now. The DNS handling and network config handling for SuSE looks to be kind of broken, but fixing that is a job for another day.

* tests: Prepare distro images during asset build phaseDavid Gibson2022-07-141-113/+12
| | | | | | | | | | | | | | | | | | | | | | | 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 Gibson2022-07-141-12/+13
| | | | | | | | | | | | 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.

* tests: Search multiple places for aarch64 EDK2 bios imageDavid Gibson2022-07-141-3/+3
| | | | | | | | | | | | | | | | | Apparently qemu's ARM virt machine needs to be explicitly given a firmware image, rather than just supplying a sane default. Unfortunately the EDK2 firmware image we need isn't in the same place on all host distros. Currently the test scripts hardcode the Debian location, meaning it will break on hosts that have it somewhere else. This patch searches multiple locations for the firmware, and creates a local link during the asset build phase, which the tests can then use. For now it only searches the locations used by Debian and Fedora, but that's a small improvement in robustness already, and can be later improved further if we need to.

* Invoke specific qemu-system-* binariesDavid Gibson2022-07-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | 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 Gibson2022-07-141-4/+4
| | | | | | | | | | | | 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.

* tests: Simplify explicit checks for command successDavid Gibson2022-05-191-22/+11
| | | | | | | | | A number of individual test cases use '*out' commands to check for success of specific commands they've issued.

* test: Add distribution tests for several architectures and kernel versionsStefano Brivio2022-01-281-0/+343
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.
