* test: Kill qemu by pidfile rather than ^CDavid Gibson2022-08-201-8/+12
| | | | | | | | | | | | | Currently in at least some of the testcases we kill qemu processes we're done with by issuing a Control-C to the tmux panel it's running in. That makes things harder as we try to move towards allowing "headless" testing without tmux. So, instead always use an explicit kill on a pid derived from a pidfile for killing qemu. Note that we don't need to remove the pidfiles afterwards, because qemu does that itself when terminated. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Log debugging output from test scriptDavid Gibson2022-08-201-0/+2
| | | | | | | | | | | | | | | | | | | The test scripts run with sh -e, which means they will stop if any commands return an error. That's generally desirable, because we won't continue after things are hopeless due to an earlier step failing. Unfortunately, the tmux setup we run the script in means it's not obvious where any error messages related to such a failure will go. Depending on exactly where the error occurs they might go to the original terminal hidden behind tmux, or they might go to a tmux panel that's not visible in the normal layouts. To make it easier to find such error message, redirect direct output and errors from the test script itself to a 'script.log' file in the logs directory. When in DEBUG=1 mode, additionaly 'set -x' so we log all the commands we execute to that file. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Use shutdown test for pastaDavid Gibson2022-08-203-5/+4
| | | | | | | | | For the passt and passt_in_ns tests we have a "shutdown" testcase that checks for any errors from the passt process we were using (including valgrind warnings). Do the same for pasta tests, so that we catch any error codes from the pasta process. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Rename slightly misleading "valgrind" testsDavid Gibson2022-08-204-12/+13
| | | | | | | | | | | | | | | | | | | The "valgrind" test cases are designed to pick up errors reported when passt is running under valgrind. But what it actually does is just kill the passt process, then see if it had a non-zero exit code. That means it will equally well pick up any other problems which caused passt to exit with an error status: either something detected within passt or as a result of passt being killed by an unexpected signal. The fact that the "valgrind" test is actually responsible for shutting down the passt process is non-obvious and can lead to problems when selectively running tests during debugging. Rename the "valgrind" tests to "shutdown" tests and run it regardless of whether we're using valgrind or not. This allows us to remove an ugly speacial case in the passt_in_ns teardown code.

* test: Only select a single interface or gateway in testsDavid Gibson2022-08-204-7/+7
| | | | | | | | | | The queries we use in the test scripts to locate the external interface or gateway can return multiple results. We get away with this because the way we parse command output only looks at the last line. It's not really correct, though, and improvements to our handling of command output will mean it breaks.

* test: Split setup/teardown functions for build and distro testsDavid Gibson2022-08-202-0/+19
| | | | | | | | | | | | Currently the build tests and distro tests share a common setup function. That works for now, but changes we want to make will mean they need slightly different setup, so split the setup functions in preparation. Currently, neither build nor distro tests have any teardown function. Again, future changes are going to mean we need to do some teardown, so create some empty for now teardown functions in preparation. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | Both clang-tidy and cppcheck linting are handled by the same test file, test/build/static_checkers. The two linters are independent of each other though, and each one takes quite a long time.

* test: Convert distro tests to use socat instead of nc/ncatDavid Gibson2022-08-204-52/+74
| | | | | | | | | | | | | | | | | 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.

* Makefile: Ugly hack to get a "plain" Markdown version of READMEStefano Brivio2022-08-203-3/+3
| | | | | | | | | | | | | | | | | | Distribution packages reasonably expect to have a human-readable Markdown version of the README under /usr/share/doc/, but all we have right now is a heavily web-oriented version. Introduce a ugly hack to strip web-oriented parts from the current README and install it. It should probably work the other way around: a human-readable README could be used as a source for the web page. But cgit needs a file that's in the tree, not something that can be built, and https://passt.top/ is based on cgit. It should eventually be doable to work around this in cgit, instead.

* Separately locate external interfaces for IPv4 and IPv6David Gibson2022-07-304-5/+8
| | | | | | | | | | | | | | | | | Now that the back end allows passt/pasta to use different external interfaces for IPv4 and IPv6, use that to do the right thing in the case that the host has IPv4 and IPv6 connectivity via different interfaces. If the user hasn't explicitly chosen an interface, separately search for a suitable external interface for each protocol. As a bonus, this substantially simplifies the external interface probe. It also eliminates a subtle confusing case where in some circumstances we would pick the first interface in interface index order, and sometimes in order of routes returned from netlink. On some network configurations that could cause tests to fail, because the logic in the tests was subtly different (it always used route order).

* tests: Correct determination of host interface name in testsDavid Gibson2022-07-302-2/+2
| | | | | | | | | | | | | By default, passt itself attaches to the first host interface with a default route. However, when determining the host interface name the tests implicitly select the *last* host interface: they use a jq expression which will list all interfaces with default routes, but the way output detection works in the scripts, it will only pick up the last line. If there are multiple interfaces with default routes on the host, and they each have a different address, this can cause spurious test failures.

* 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: No need to retrieve host ifname in ndp/pastaDavid Gibson2022-07-221-3/+2
| | | | | | | | | With pasta, the namespace interface name is generally the same as the host interface name.

* tests: Clean up better after iperf testsDavid Gibson2022-07-221-1/+1
| | | | | | | | | | | | | The iperf based test commands create a bunch of .bw and .pid files for each iperf client and server. The server side .bw files are cleaned up afterwards, but the pid files are not, and none of the client side files are cleaned up. The latter doesn't really matter when the client is run on ephemeral guests, but sometimes we run it in a namespace that shares the filesystem with the host. Clean up all of these files after the tests. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Use dhclient --no-pid for namespaces in two_guests testsDavid Gibson2022-07-221-4/+4
| | | | | | | | | | Before starting the guests, these tests configure addresses in a pasta namespace using dhclient. However, because it's a user namespace, it's not running as "real" root and can't write to the dhclient pid file. This doesn't stop it working, but causes an ugly error message which we can avoid by using the --no-pid option. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Remove unnecessary truncation of temporary files in udp testsDavid Gibson2022-07-223-18/+0
| | | | | | | | | All the UDP tests use :> to truncate some temporary data files. This appears to be so that they're empty before writing data to them with tee.

* tests: Remove unnecessary ^D in passt_in_ns teardownDavid Gibson2022-07-221-2/+0
| | | | | | | | | | | | | | | | | teardown_passt_in_ns() sends a ^D to the NS pane, which appears to be intended to terminate the nsenter running there, leaving the namespace. However, we've also sent a ^D to the PASST pane which will exit the pasta instance which created the namespace. With the namespace destroyed the nsenter in the NS pane will be killed, so it does not need to be exited explicitly. In fact sending the extra ^D can be harmful, since it will exit the shell in which the nsenter was run, causing the whole pane to be closed. That can then mean that the "pane_wait NS" hangs indefinitely. I believe this will sometimes work, because there's a race between the various options here, but it should be more reliable without the extra ^D.

For some upcoming changes, however, we'll be wanting to use socat.

* tests: Fix detection of empty 'hout' responses in passt{,_in_ns} testsDavid Gibson2022-07-221-0/+14
| | | | | | | | | | | | | | The dhcp/passt and dhcp/passt_in_ns tests at least, and maybe others use 'hout' commands that need to be able to detect empty output. However, we don't set PS1, which means the screen-scraping logic which detects this may not be reliable. In addition, if the host is using a recent bash, it will have bracketed paste mode enabled which will also add escape codes which will mess up the empty output detection. Set the prompt and disable bracketed paste mode from the passt and passt_in_ns setups to avoid these problems. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Correctly handle domain search list in dhclient-scriptDavid Gibson2022-07-221-3/+3
| | | | | | | | | | | Currently our small custom dhclient-script only handles the 'domain-name' option, which can just list a single domain, not the 'domain-search' option, which can handle several. Correct it to handle both. We also weren't emptying the resolv.conf file before we began, which could lead to surprising contents after multiple DHCP transactions.

* tests: Handle the case of a nameserver on host localhostDavid Gibson2022-07-221-2/+2
| | | | | | | | | | | | We previously introduced a change to passt to handle the case where the host machine is its own nameserver - so resolv.conf points to 127.0.0.1. In this case we advertize the gateway as the DNS server for the guest, which in turn will be redirected back to the host by existing passt logic.

* tests: More robust parsing of resolv.conf for DHCP testsDavid Gibson2022-07-221-8/+8
| | | | | | | | | | | | | | | | | To check publishing of DNS information via DHCP, we need to extract a list of nameservers and/or search domains from resolv.conf in the test script. The current version (usually) leaves the result with a trailing ','. That's usually ok because it happens on both guest and host sides. However it's kind of confusing, and might stop working if the host had a resolv.conf without a trailing \n on the last line. It also makes some later changes we'll need more difficult. So, normalize the output from resolv.conf a bit further, removing any trailing ','. It turns out we can do this with a slightly less complex sed expression than the one we already have.

| | | | | | | | | | | | Modern Fedora (and RHEL) systems have /sbin as a symlink to /usr/sbin (along with a number of similar links).

| | | | | | | | | | | | AFAICT the symlink we created in mbuto from /usr/bin/bash to /bin/sh was for the benefit of a dhclient-script which used /usr/bin/bash as its interpreter (e.g. in Fedora).

| | | | | | | | | | | | | | | | | | 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 Gibson2022-07-146-325/+69
| | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | Currently test/run uses wildcards to run all of the tests in a directory. However, that wildcard list is filtered down by the "onlyfor" directives in the test files... usually to a single file. Therefore, just explicitly list the files we *really* want to run for this test mode. This makes it easier to see at the top level what tests will be executed, and to change that list temporarily while debugging specific failures. This means the "onlyfor" directive no longer has any purpose, and we can remove it. "onlyfor" was also the only used of the $MODE variable, so we can remove that too.

| | | | | | | | | | | | | | | The top level listing control of which tests to run is in test/run, however it uses the test() function which runs an entire directory of test files, filtered by some criteria. This makes it awkward to narrow down to a subset of tests when debugging a specific failure. To make this easier, have test() take an explicit list of test files to run, and have the caller in test/run handle the directory traversal. The construct we use for this is pretty awkward to handle the fact that we're in the source tree root directory rather than test/ at this point in test/run. Later cleanups will improve that.

It turns out we only use this functionality in one place - to make the "make install" test run after the plain "make" test. We also already have a simpler way of making sure tests run in a specific order: just put them into the same test script file.

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 Gibson2022-07-146-31/+40
| | | | | | | | | | | | | | | | | | | | | | 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).

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>
