* Clean up and rename conf_ns_open()David Gibson2022-09-133-71/+68
| | | | | | | | | | | | | | conf_ns_open() opens file descriptors for the namespaces pasta needs, but it doesnt really have anything to do with configuration any more. For better clarity, move it to pasta.c and rename it pasta_open_ns(). This makes the symmetry between it and pasta_start_ns() more clear, since these represent the two basic ways that pasta can operate, either attaching to an existing namespace/process or spawning a new one. Since its no longer validating options, the errors it could return shouldn't cause a usage message. Just exit directly with an error instead. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Consolidate validation of pasta namespace optionsDavid Gibson2022-09-131-41/+42
| | | | | | | | | | | | | | | | | | | | There are a number of different ways to specify namespaces for pasta to use. Some combinations are valid and some are not. Currently validation for these is spread across several places: conf_ns_pid() validates PID options specifically. Near its callsite in conf() several other checks are made. Some additional checks are made in conf_ns_open() and finally theres a check just before the call to pasta_start_ns(). This is quite hard to follow. Make it easier by putting all the validation logic together in a new conf_pasta_ns() function, which subsumes conf_ns_pid(). This reveals that some of the checks were redundant with each other, so remove those. For good measure, rename conf_netns() to conf_netns_opt() to make it clearer its handling just the --netns option specifically, not overall configuration of the netns.

* Move self-isolation code into a separate fileDavid Gibson2022-09-138-169/+189
| | | | | | | | passt/pasta contains a number of routines designed to isolate passt from the rest of the system for security. These are spread through util.c and passt.c. Move them together into a new isolation.c file. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Safer handling if we can't open /proc/self/uid_mapDavid Gibson2022-09-131-2/+6
| | | | | | | | | | | | | | | | | passt is allowed to run as "root" (UID 0) in a user namespace, but notas real root in the init namespace. We read /proc/self/uid_map to determine if we're in the init namespace or not. If we're unable to open /proc/self/uid_map we assume we're ok and continue running as UID 0. This seems unwise. The only instances I can think of where uid_map won't be available are if the host kernel doesn't support namespaces, or /proc is not mounted. In neither case is it safe to assume we're "not really" root and continue (although in practice we'd likely fail for other reasons pretty soon anyway). Therefore, fail with an error in this case, instead of carrying on. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Consolidate determination of UID/GID to run asDavid Gibson2022-09-133-59/+73
| | | | | | | | | | | | Currently the logic to work out what UID and GID we will run as is spread across conf(). If --runas is specified it's handled in conf_runas(), otherwise it's handled by check_root(), which depends on initialization of the uid and gid variables by either conf() itself or conf_runas(). Make this clearer by putting all the UID and GID logic into a single conf_ugid() function. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Split checking for root from dropping root privilegeDavid Gibson2022-09-134-7/+33
| | | | | | | | | | | | | | | | | | check_root() both checks to see if we are root (in the init namespace), and if we are drops to an unprivileged user. To make future cleanups simpler, split the checking for root (now in check_root()) from the actual dropping of privilege (now in drop_root()). Note that this does slightly alter semantics. Previously we would only setuid() if we were originally root (in the init namespace). Now we will always setuid() and setgid(), though it won't actually change anything if we weren't privileged to begin with. This also means that we will now always attempt to switch to the user specified with --runas, even if we aren't (init namespace) root to begin with. Obviously this will fail with an error if we weren't privileged to start with. --help and the man page are updated accordingly. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* test: Rewrite test_iperf3David Gibson2022-09-074-44/+31
| | | | | | | | | | | | | | | test_iperf3() is a pretty inscrutable mess of nested background processes. It has a number of ugly sleeps needed to wait for things to complete. Rewrite it to be cleaner: * Use the construct (a & b & wait) to run 'a' and 'b' in parallel, but then wait for them both to complete before continuing * This allows us to wait for both the server and client to finish, rather than sleeping * Use jq to do all the math we need to get the final result, rather than jq followed by some complicated 'bc' mangling Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* test: Combine iperf3c and iperf3s into a single DSL commandDavid Gibson2022-09-075-197/+122
| | | | | | | | | | | | | | | | | These two commands in the DSL to run an iperf client and server are always used together, and some of the parameters must match between them. The iperf3s must also be run more or less immediately after iperf3c, since iperf3c will run a client in the background after a sleep and requires a server to be running before it will work. A bunch of things can be made cleaner if we make a single DSL command that runs both sides of the test. For now make the combined command work exactly like the two commands together did, warts and all. This does lose the ability for the DSL scripts to give additional options to the iperf3 server, but we weren't using that anyway. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

I originally used that hack to avoid introducing a delay which is needed when running it on TCG.

* Allow pasta to take a command to executeDavid Gibson2022-08-304-25/+51
| | | | | | | | | | | | | | When not given an existing PID or network namspace to attach to, pasta spawns a shell. Most commands which can spawn a shell in an altered environment can also run other commands in that same environment, which can be useful in automation. Allow pasta to do the same thing; it can be given an arbitrary command to run in the network and user namespace which pasta creates. If neither a command nor an existing PID or netns to attach to is given, continue to spawn a default shell, as before. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* More deterministic detection of whether argument is a PID, PATH or NAMEDavid Gibson2022-08-301-82/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pasta takes as its only non-option argument either a PID to attach to the namespaces of, a PATH to a network namespace or a NAME of a network namespace (relative to /run/netns). Currently to determine which it is we try all 3 in that order, and if anything goes wrong we move onto the next. This has the potential to cause very confusing failure modes. e.g. if the argument is intended to be a network namespace name, but a (non-namespace) file of the same name exists in the current directory. Make behaviour more predictable by choosing how to treat the argument based only on the argument's contents, not anything else on the system: - If it's a decimal integer treat it as a PID - Otherwise, if it has no '/' characters, treat it as a netns name (ip-netns doesn't allow '/' in netns names) - Otherwise, treat it as a netns path If you want to open a persistent netns in the current directory, you can use './netns'. This also allows us to split the parsing of the PID|PATH|NAME option from the actual opening of the namespaces. In turn that allows us to put the opening of existing namespaces next to the opening of new namespaces in pasta_start_ns. That makes the logical flow easier to follow and will enable later cleanups. Caveats: - The separation of functions mean we will always generate the basename and dirname for the netns_quit system, even when using PID namespaces. This is pointless, since the netns_quit system doesn't work for non persistent namespaces, but is harmless. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* Move ENOENT error message into conf_ns_opt()David Gibson2022-08-301-2/+1

* Remove --nsrun-dir optionDavid Gibson2022-08-302-26/+4
| | | | | | | | | | | | | pasta can identify a netns as a "name", which is to say a path relative to (usually) /run/netns, which is the place that ip(8) creates persistent network namespaces. Alternatively a full path to a netns can be given. The --nsrun-dir option allows the user to change the standard path where netns names are resolved. However, there's no real point to this, if the user wants to override the location of the netns, they can just as easily use the full path to specify the netns.

| | | | | | | | | The man page states that the --userns option can be given either as a path or as a name relative to --nsrun-dir.

However, handling the optional argument requires some ugly special case handling if it's the last option on the command line, and has potential ambiguity with non-option arguments used with pasta. It can also make it more confusing to read command lines. Simplify the logic here by replacing the non-argument versions with an explicit "-D none" or "-S none".

| | | | | | | | | | | | | | | | There are several places in the passt code where we have lint overrides because we're not adding CLOEXEC flags to open or other operations. Comments suggest this is because it's before we fork() into the background but we'll need those file descriptors after we're in the background.

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.

| | | | | | | | | | | | | | | | | | | 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: 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.
