* 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. The dhcp/passt doesn't handle this case correctly, so add some logic to account for it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* 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.

* tests: Add some extra dhclient support directories to mbuto.imgDavid Gibson2022-07-221-1/+1
| | | | | | | | Although it can operate without them, dhclient can issue errors if it doesn't have /var/run to write a pid file and /var/lib to write a leases file. Create those in mbuto.img to stop it complaining. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* tests: Let Fedora find dhclient-script in /usr/sbinDavid Gibson2022-07-221-0/+1
| | | | | | | | | | | | Modern Fedora (and RHEL) systems have /sbin as a symlink to /usr/sbin (along with a number of similar links). Along with that it expects to find dhclient-script in /usr/sbin/dhclient-script rather than /sbin/dhclient-script. Link them together in our mbuto image so that the Fedora build of dhclient can find it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Remove no longer needed /usr/bin/bash linkDavid Gibson2022-07-221-2/+1
| | | | | | | | | | | | 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). That was a bit risky if the script really did require bash and we linked it to dash or another shell. We now supply our own custom dhclient-script, so we don't need the link any more.

If qrap sends an ARP request as a probe in that case, it will receive no answer and move on, trying to find another instance. Add a second probe frame, a hardcoded neighbour solicitation, so that we get a neighbour advertisement if IPv6 is enabled. Without this change, IPv6-only operation is completely broken.

| | | | | | | | | | | | | | | | | | | | | This is useful in environments where we want to forward a large number of ports, or all non-ephemeral ones, and some other service running on the host needs a few selected ports. I'm using ~ as prefix for the specification of excluded ranges and ports to avoid the need for explicit command line quoting. Ranges and ports can be excluded from given ranges by adding them in the comma-separated list, prefixed by ~. Some quick examples: -t 5000-6000,~5555: forward ports 5000 to 6000, but not 5555 -t ~20000-20010: forward all non-ephemeral, allowed ports, except for ports 20000 to 20010 ...more details in usage message and man page.

* conf: Fix initialisation of IPv6 unicast and link-local addressesStefano Brivio2022-07-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | In commit 675174d4ba25 ("conf, tap: Split netlink and pasta functions, allow interface configuration"), I broke the initial setting of the observed IPv6 addresses in two ways: - the size copied from the configured addresses corresponds to an IPv4 address, not to an IPv6 address - the observed link-local address is initialised to the configured unicast address, not the link-local one If we haven't seen the guest using some type of addresses yet, we should default to the configured values, hence these initial settings: fix both. This resulted in UDP flows to the guest from a unique local address on the network not working before the guest shows passt a valid address itself, as reported by Alona.

* tests: Remove unused DNS6 calculation from fedora testsDavid Gibson2022-07-143-4/+3
| | | | | | | | | | | | | | | | | | 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>

* tests: Explicitly list test files in test/run, remove "onlyfor" supportDavid Gibson2022-07-1423-67/+31
| | | | | | | | | | | | | | | | | 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.

* tests: Don't automatically traverse directories of test filesDavid Gibson2022-07-142-26/+26
| | | | | | | | | | | | | | | 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.

* tests: Remove not-very-useful "req" directiveDavid Gibson2022-07-143-53/+31
| | | | | | | | | | | | | | | | | The test scripts support a "req" directive which requires one test script to be run before another. It's implemented by doing a topological sort based on these directives in the runner scripts, which is about as awkward as you'd expect in Bourne shell. 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. So, remove support for the "req" directive and just fold the build/all and build/install test scripts together. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* tests: Search multiple places for aarch64 EDK2 bios imageDavid Gibson2022-07-146-13/+30
| | | | | | | | | | | | | | | | | 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.

* tests: Move mbuto download and execution to asset buildDavid Gibson2022-07-143-19/+16
| | | | | | | | | | | | Move the download of mbuto and using it to create a sample initramfs to the asset build makefile, rather than embedding it in the test scripts themselves. The two_guests tests used to use two separate copies of the mbuto image. As an initramfs the mbuto image is strictly readonly though, so that's not necessary. So, also use the same image for both guests. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* tests: Introduce makefile for building test assetsDavid Gibson2022-07-142-1/+28
| | | | | | | | | | | | | | A number of passt/pasta testcases have initial steps which are just about building images or other assets we need for the test proper. Repeating these for each test run can be quite costly. This patch makes a start on moving this sort of test asset building to a separate phase before running the tests proper. For now just add a Makefile to handle the asset building (although it doesn't build anything yet), and make the path where we'll be building the assets available to the tests.

* Invoke specific qemu-system-* binariesDavid Gibson2022-07-147-34/+43
| | | | | | | | | | | | | | | | | | | | | | 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 Gibson2022-07-142-6/+6
| | | | | | | | | | | | 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>
* Handle the case of a DNS server on localhostDavid Gibson2022-07-141-0/+16
| | | | | | | | | | | | | | | | | | By default, passt detects the nameserver used by the host system by reading /etc/resolv.conf, and advertises that to the guest via DHCP. However this breaks down if the host's nameserver is local (on 127.0.0.1 or ::1); connecting to localhost on the guest won't reach the host's nameserver. Using a local nameserver is a reasonably common case when using dnsmasq or similar to merge name resolution on a home network with name resolution from an organization-private VPN. We already have the gateway mapping support to allow reaching host-local services from the guest via the address of the default gateway. Add code to detect the case of a local DNS server and use the gateway mapping to advertise it usefully to the guest. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | | | | | | | | | | | | | | | | David reports that dhclient-script(8) on Fedora needs a number of binaries that are not included in PROGS of the current mbuto profile, and we would also need to include hostnamectl(1) there, which will fail without a systemd init. Embed a minimal script for dhclient(8) in the profile itself, written to /sbin/dhclient-script at boot, to just check what we need to check out of DHCP and DHCPv6 functionality. While at it, drop busybox and logger from PROGS, as we don't need them, and add hostname(1). While DHCP option 12 isn't supported yet by the DHCP implementation in passt, we should probably add it soon.

| | | | | | | | | | | | | | | | | | In commit fca5e11773d0 ("qrap: Add probe retry on connection reset from passt for KubeVirt integration") I just used errno to check if the connection was reset on recv(), but perror() might set it to EINVAL if e.g. an underlying logging mechanism fails, so we won't actually catch the connection reset. And in case recv() returns 0, errno won't be set, but we're still using it without resetting it first, which leads to unpredictable results in that case. Reset errno before probing with connect(), send() and recv(), and save it for later checks before calling perror().

* Add cleaner line-by-line reading primitivesDavid Gibson2022-07-063-4/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Two places in passt need to read files line by line (one parsing resolv.conf, the other parsing /proc/net/*. They can't use fgets() because in glibc that can allocate memory. Instead they use an implementation line_read() in util.c. This has some problems: * It has two completely separate modes of operation, one buffering and one not, the relation between these and how they're activated is subtle and confusing * At least in non-buffered mode, it will mishandle an empty line, folding them onto the start of the next non-empty line * In non-buffered mode it will use lseek() which prevents using this on non-regular files (we don't need that at present, but it's a surprising limitation) * It has a lot of difficult to read pointer mangling Add a new cleaner implementation of allocation-free line-by-line reading in lineread.c. This one always buffers, using a state structure to keep track of what we need. This is larger than I'd like, but it turns out handling all the edge cases of line-by-line reading in C is surprisingly hard. This just adds the code, subsequent patches will change the existing users of line_read() to the new implementation. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | pasta, pasta.avx2 and pasta.1 are all generated as a link to the corresponding passt file. We can consolidate the 3 rules for these targets into a single pattern rule. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Makefile: Use $(BIN) and $(MANPAGES) variable to simplify several targetsDavid Gibson2022-06-185-18/+16
| | | | | | | | | | | | | | 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.
