We don't set any, but we should use them if they are passed in the

On new Ubuntu 22.04 images, stopping systemd-resolved to get the
dhclient script override resolv.conf doesn't work anymore. I
originally used that hack to avoid introducing a delay which is
needed when running it on TCG.
Keep systemd-resolved running instead, and wait for it to be ready
by retrying to resolve a domain a few times before installing
packages, so that we don't add another ugly delay that might
unnecessarily slow down things even further.

Declaring them as required_argument in the longopts array specifies
validation, but doesn't affect how optind is increased after parsing
their values.
Currently, passing one of these options as last option causes pasta
to handle their own values as path to a binary to execute.

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.

When attaching to an existing namespace, pasta can take a PID or the name
or path of a network namespace as a non-option parameter. We disambiguate
based on what the parameter looks like. Make this more explicit by using
a --netns option for explicitly giving the path or name, and treating a
non-option argument always as a PID.

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.

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. This is not correct: as the name
suggests --nsrun-dir is (correctly) used only for *netns* resolution, not
*userns* resolution.

Both the -D (--dns) and -S (--search) options take an optional argument.
If the argument is omitted the option is disabled entirely. 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".

The --pcap or -p option can be used with or without an argument. If given,
the argument gives the name of the file to save a packet trace to. If
omitted, we generate a default name in /tmp.
Generating the default name isn't particularly useful though, since making
a suitable name can easily be done by the caller. Remove this feature.

Commit a951e0b9efcb ("conf: Add --runas option, changing to given UID

used to add supplementary groups corresponding to the user we'll

However, if the original user belongs to supplementary groups
(usually not the case, if started as root), we don't drop those,
now, and rpmlint says:

supplementary group we might currently have, before changing GID

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.
However, as the name suggests CLOEXEC closes on exec(), not on fork(). The
only place we exec() is either super early invoke the avx2 version of the
binary, or when we start a shell in pasta mode, which certainly *doesn't*
require the fds in question.
Add the CLOEXEC flag in those places, and remove the lint overrides.

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.

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.

For the passt and passt_in_ns tests we have a "shutdown" testcase that

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.

We've recently converted most of our tests to use socat instead of

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.

git_dir_changelog is useful in theory, but it requires pairs of
annotated tags, which should be generated by rpkg itself to make any
sense, implying a relatively heavyweight interaction whenever I want
to push a new package version.
Also, the default content of the changelog entries include the full
list of changes, but the Fedora Packaging Guidelines specifically
mention that:
[t]hey must never simply contain an entire copy of the source
CHANGELOG entries.
We don't have a CHANGELOG file, but the full git history is
conceptually equivalent for this purpose, I guess.
Introduce our own passt_git_changelog() rpkg macro, building
changelog entries, using tags in the form DATE-SHA, where DATE
is an ISO 8601 date representation, and SHA is a short (7-digits)
form of the head commit at a given moment (git push).
These changelog entries mention, specifically, changes to the
packaging information itself (entries under contrib/fedora), and
simply report a link to cgit for the ranges between tags.

It should probably work the other way around: a human-readable README

https://passt.top/ is based on cgit. It should eventually be doable
