Hi Stefano, Here's another batch of fixes for the passt/pasta tests. With this lot I'm now able to get the build and pasta tests passing on my Fedora workstation. The passt and distro tests still fail or crash, I'm continuing to look at those (it looks like there are some very fragile behaviours in qrap which means they're not even getting started). David Gibson (5): tests: Use more explicit netcat options for distro/fedora tests Don't abbreviate ip(8) arguments in examples and tests Tweak dhclient arguments for readability Use dhclient instead of udhcpc tests: Use nmap-ncat instead of openbsd netcat for pasta tests contrib/kata-containers/README.md | 2 +- doc/demo.sh | 8 ++--- passt.1 | 16 +++------ test/README.md | 2 +- test/demo/passt | 16 ++++----- test/demo/pasta | 24 ++++++------- test/demo/podman | 20 +++++------ test/dhcp/passt | 24 ++++++------- test/dhcp/pasta | 26 +++++++------- test/distro/fedora | 14 ++++---- test/distro/ubuntu | 4 +-- test/icmp/passt_in_ns | 4 +-- test/lib/setup | 12 +++---- test/ndp/passt | 12 +++---- test/ndp/pasta | 12 +++---- test/perf/passt_tcp | 8 ++--- test/perf/passt_udp | 8 ++--- test/perf/pasta_tcp | 6 ++-- test/perf/pasta_udp | 6 ++-- test/tcp/passt | 6 ++-- test/tcp/passt_in_ns | 22 ++++++------ test/tcp/pasta | 60 +++++++++++++++---------------- test/two_guests/basic | 26 +++++++------- test/udp/passt | 6 ++-- test/udp/passt_in_ns | 14 ++++---- test/udp/pasta | 35 +++++++++--------- 26 files changed, 193 insertions(+), 200 deletions(-) -- 2.36.1
distro/fedora contains two versions of the basic tests, used for different Fedora versions. One uses explicit listening address for netcat in some extra places, the other does not. Apparently the older netcat versions didn't require the explicit addresses. Not supplying addresses doesn't test anything useful though, just a detail in netcat's behaviour. So, it's cleaner to just always supply explicit addresses. In addition, we're explicitly expecting the nmap version of ncat, also known as "ncat". So, it's more explicit what we're after if we invoke it via that name rather than "nc", which will go via an /etc/alternatives link.

ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't
make
for very readable scripts and examples when shown that way.

2.36.1
A number of tests and examples use dhclient in both IPv4 and IPv6 modes.
We use "dhclient -6" for IPv6, but usually just "dhclient" for IPv4.
Add
an explicit "-4" argument to make it more clear and explicit.
In addition, when dhclient is run from within pasta it usually won't be
"real" root, and so will not have access to write the default global pid
file. This results in a mostly harmless but irritating error:
Can't create /var/run/dhclient.pid: Permission denied
We can avoid that by using the --no-pid flag to dhclient.

2.36.1
For some reason, the passt/pasta tests and examples use dhclient for
DHCPv6, but in most cases use udhcpc for DHCPv4. Change it to use dhclient
for both DHCPv4 and DHCPv6. This means one less tool we need for testing,
plus dhclient is easily available on Fedora whereas udhcpc is not.
Note that the passt tests still rely on udhcpc indirectly because mbuto
wants to put it into the guest images it generates.

So I think we could potentially restore that kind of testing, but move it into tests with specifically constructed guests (or container images) where we can choose the distro and get udhcpc (or other clients to test those to.

A number of the testcases use options specific the OpenBSD version of
netcat. That's available in Debian, but not easily available in Fedora.
Switch the pasta tests to using the nmap version of netcat (a.k.a. ncat).
This is easily available in both Debian and Fedora, and appears to be a
bit more modern and maintained as well.
ncat generally requires explicit listen addresses (which is good for
clarity anywhere). Its default options appear to remove the need for the
-N and -q options.

That's available in Debian, but not easily available in Fedora. Switch the pasta tests to using the nmap version of netcat (a.k.a. ncat). This is easily available in both Debian and Fedora, and appears to be a bit more modern and maintained as well. ncat generally requires explicit listen addresses (which is good for clarity anywhere). Its default options appear to remove the need for the -N and -q options.

With this lot I'm now able to get the build and pasta tests passing on my Fedora workstation. The passt and distro tests still fail or crash, I'm continuing to look at those (it looks like there are some very fragile behaviours in qrap which means they're not even getting started).Thanks a lot! The entire series looks good to me, I'm currently running the tests with it, I'll apply once they complete. -- Stefano
