* test: Add Podman system test with bats for pasta2023_09_07.ee58f37Stefano Brivio2023-09-073-2/+27
| | | | | | | | | | | | | | | | | | | Ugly as hell, but we keep breaking things otherwise, and I keep forgetting to run this manually (as long as it's based on my local Podman setup, that's the only alternative). We need to clone the Podman repository as distribution packages don't contain test scripts, typically. While at it, build the latest version which is what really matters. As we're planning anyway to revamp the test framework, I'd be inclined to just add this without too many thoughts, and have it as a nice-to-have requirement reminder for the new framework.

* test/nstool: Fix fd leak in accept() loopDavid Gibson2023-05-231-0/+2

* test/nstool: Provide useful error if given a path that's too longDavid Gibson2023-05-231-8/+14
| | | | | | | | | | | | | Normal filesystem paths can be very long (PATH_MAX is around 8k), however Unix domain sockets can only use relatively short paths (UNIX_PATH_MAX is 108 on Linux). Currently nstool will simply truncate paths that are too long, leading to difficult to understand failures. Make such failures clearer, with an explicit error message if given a path that's too long.

| | | | | | | | | | If we enter a mount namespace with nstool exec our working directory will be changed to / in the new mount ns.

* test: Remove race between commands run in the same contextDavid Gibson2023-04-081-2/+2
| | | | | | | | | | | | | context_run() has a race condition if two commands are run in close proximity (generally involving at least one in the background). Because we always use the same name for the temporary fifo files, if another command is issued while the fifos for the first still exist, mkfifo will fail, typically causing the entire test script to jam.

* passt: Relicense to GPL 2.0, or any later versionStefano Brivio2023-04-0647-47/+47
| | | | | | | | | | | | | | | | | | | In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas.

| | | | | | | | | | | | | | | | | | | | On shell 'exit' commands, running shells from pasta, we might get: Cannot set tty process group (No such process) as some TTY devices might be unaccessible. This is harmless, but after commit "pasta: propagate exit code from child command", we'll get test failures there, at least with dash. Ignore those explicitly with a ugly workaround: we can't simply do something like: exit || : because the failure is reported by the shell itself once it exits, regardless of the command evaluation.

* test: Wait for network before starting passt in two_guests setupStefano Brivio2022-11-041-0/+2
| | | | | | | | | | | | | As pasta now configures that target network namespace with --config-net, we need to wait for addresses and routes to be actually present. Just sending netlink messages doesn't mean this is done synchronously. A more elegant alternative, which probably makes sense regardless of this test setup, would be to query, from pasta, addresses and routes we added, and wait until they're there, before proceeding.

* test: Add memory/passt test casesStefano Brivio2022-11-046-1/+289
| | | | | | | | | | | | | | | | | | | | | | | | These show a summary of memory usage in kernel and userspace with different port forwarding configurations, details of userspace usage using 'nm' (passt only uses statically allocated memory), and details of kernel memory from slab reporting facilities. This adds a new test image, mbuto.mem.img, with harcoded IPv4 and IPv6 addresses and routes, and just the tools we need to start and stop passt, to report from /proc/slabinfo, /proc/meminfo, and to print and parse symbol sizes using nm(1). passt can't pivot_root() for sandboxing purposes on ramfs, so we need to create another filesystem and chroot into it, first. We don't want to use pane context functions, as we're checking memory usage for sockets: resort to screen-scraping.

* test: Add log file tests for pasta plus corresponding layout and setupStefano Brivio2022-10-265-1/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To test log files on a tmpfs mount, we need to unshare the mount namespace, which means using a context for the passt pane is not really practical at the moment, as we can't open a shell there, so we would have to encapsulate all the commands under 'unshare -rUm', plus the "inner" pasta command, running in turn a tcp_rr server. It might be worth fixing this by e.g. detecting we are trying to spawn an interactive shell and adding a special path in the context setup with some form of stdin redirection -- I'm not sure it's doable though. For this reason, add a new layout, using a context only for the host pane, while keeping the old command dispatch mechanism for the passt pane. We also need a new setup function that doesn't start pasta: we want to start and restart it with different options. Further, we need a 'pint' directive, to send an interrupt to the passt pane: add that in lib/test. All the tests before the one involving tmpfs and a detached mount namespace were also tested with the context mechanism. To make an eventual conversion easier, pass tcp_crr directly as a command on pasta's command line where feasible. While at it, fix the comment to the teardown_pasta() function. The new test set can be semi-conveniently run as: ./run pasta_options/log_to_file and it checks basic log creation, size of the log file after flooding it with debug entries, rotations, and basic consistency after rotations, on both an existing filesystem and a tmpfs, chosen as it doesn't support collapsing data ranges via fallocate(), hence triggering the fall-back mechanism for logging rotation.

| | | | | | | | | | The distro and performance tests are by far the slowest part of the passt testsuite.

For example: ./run passt/ndp will trigger the 'passt' setup and teardown functions.

* test: Simplify data handling for transfer testsDavid Gibson2022-09-2910-294/+214
| | | | | | | | | | | | | | | | | | | | | | | | | | Many of our tests are based around performing transfers of sample data across passt/pasta created links. The data flow here can be a bit hard to follow since, e.g. we create a file transfer it to the guest, then transfer it back to the host across several different tests. This also means that the test cases aren't independent of each other. Because we don't have the original file available at both ends in some cases, we compare them by generating md5sums at each end and comparing them, which is a bit complicated. Make a number of changes to simplify this: 1. Pre-generate the sample data files as a test asset, rather than building them on the fly during the tests proper 2. Include the sample data files in the mbuto guest image 3. Because we have good copies of the original data available in all contexts, we can now simply use 'cmp' to check if the transfer has worked, avoiding md5sum complications. 4. Similarly we can always use the original copy of the sample data on the send side of each transfer, meaning that the tests become more independent of each other.

This isn't really part of the tests, just necessary for the operations later. We can simplify and speed this up a bit by using pasta's '--config-net' option to configure the networking for us.

We have a number of semi-arbitrary fixed sleeps to account for this.
