test/lib: Wait for DHCPv4 before starting DHCPv6 client in two_guests test

2022-09-23T00:46:24+00:00

I'm not sure why, but dhclient hangs otherwise. This reflects what we
do in the passt_in_ns setup steps.

Eventually, this whole block could go away if we let pasta configure
this network namespace with --config-net.

test: Move pidfiles and nsholder sockets into state directory

2022-09-13T09:12:41+00:00

Currently they go in the passt source tree with a fixed names, which means
their presence can mess with subsequent test runs.

test: Store pcap files in $LOGDIR instead of /tmp

2022-09-13T09:12:41+00:00

The capture files are more or less a different form of log output from the
tests, so place them in $LOGDIR.

test: Create common state directories for temporary files

2022-09-13T09:12:41+00:00

The test scripts create a bunch of temporary files to keep track of
internal state.  Some are made in /tmp with individual mktemp calls, some
go in the passt source directory, and some go in $LOGDIR.  This can
sometimes make it messy to clean up after failed test runs.

Start cleaning this up by creating a single "state" directory ($STATEBASE)
in /tmp for all the state or temporary files used by a single test run.
Clean it up automatically in cleanup() - except when DEBUG==1, because
those files can be useful for debugging test script failures.

We create subdirectories under $STATEBASE for each setup function, exposed
as $STATESETUP.  We also create subdirectories for each test script and
expose those to the scripts as __STATEDIR__.

test: Use new-style command issue for passt_in_ns tests

2022-09-13T03:32:00+00:00

Put the pieces together to use the new style context based dispatch for
the passt_in_pasta tests.

test: Use context system for two_guests tests

2022-09-13T03:32:00+00:00

Now that we have all the pieces we need for issuing commands both into
namespaces and into guests, we can use those to convert the two_guests to
using only the new style context command issue.

test: Use context system for guest commands

2022-09-13T03:32:00+00:00

Extends the context system in the test scripts to allow executing commands
within a guest.  Do this without requiring an existing network in the guest
by using socat to run ssh via a vsock connection.

We do need some additional "sleep"s in the tests, because the new
faster dispatch means that sometimes we attempt to connect before
socat has managed to listen.

For now, only use this for the plain "passt" tests.  The "passt_in_ns" and
other tests have additional complications we still need to deal with.

test: Extend context system to run commands in namespace for pasta tests

2022-09-13T03:32:00+00:00

Extend the context system to allow commands to be run in a namespace
created with unshare, and use it for the namespace used in the pasta tests.

test: Use new-style contexts for passt pane in the pasta and passt tests

2022-09-13T03:32:00+00:00

Convert the pasta and passt tests to use new-style context execution
for the things that run in the "passt" frame.  Don't touch the
passt_in_ns or two_guests tests yet, because they run passt inside a
namespace which introduces some additional complications we have yet
to handle.

test: Issue host commands via context for most tests

2022-09-13T03:32:00+00:00

Convert most of the tests to use the new-style system for issuing commands
for all host commands.  We leave the distro tests for now: they use
the same pane for both host and guest commands which we'll need some more
things to deal with.
