[PATCH v1 0/6] testing/next (netbsd stuff)

[Alex Bennée]

Hi,

As we approach hard-freeze I'm trying to temper what comes in through
the testing/next tree. However it would be nice to get the NetBSD upto
speed with the other NetBSDs. Although the serial install is working
well for me this has had a rocky road so if others could also give it
a good testing that would be great. I've also disabled one of the
regular failing tests for non-Linux targets. There are other tests
that still fail however including the tests/test-aio-multithread which
asserts in the async utils around about 20% of the time:

  assertion "QSLIST_EMPTY(&ctx->scheduled_coroutines)" failed: file
    "/home/qemu/qemu-test.nS1czd/src/util/async.c", line 279, function
    "aio_ctx_finalize"

You can run:

  make vm-build-netbsd TARGET_LIST=x86_64-softmmu BUILD_TARGET=check-unit

on repeat to trigger it. If anyone has cycles to work out why please
have a look.

The following patches need review:
   05 - tests only run ipmi bt test if CONFIG_LINUX
   06 - tests vm support sites with sha512 checksums

Alex Bennée (2):
  tests: only run ipmi-bt-test if CONFIG_LINUX
  tests/vm: support sites with sha512 checksums

Gerd Hoffmann (4):
  tests/vm: netbsd autoinstall, using serial console
  tests/vm: add console_consume helper
  tests/vm: use console_consume for netbsd
  tests/vm: update netbsd to version 8.1

[PATCH v1 1/6] tests/vm: netbsd autoinstall, using serial console

[Alex Bennée]

From: Gerd Hoffmann <kraxel@redhat.com>

Instead of fetching the prebuilt image from patchew download the install
iso and prepare the image locally.  Install to disk, using the serial
console.  Create qemu user, configure ssh login.  Install packages
needed for qemu builds.

[PATCH v1 3/6] tests/vm: use console_consume for netbsd

[Alex Bennée]

Use new helper to read all pending console output,
not just a single char.  Unblocks installer boot.

[PATCH v1 5/6] tests: only run ipmi-bt-test if CONFIG_LINUX

[Alex Bennée]

This test has been unstable on NetBSD for awhile. It seems the
mechanism used to listen to a random port is a Linux-ism (although a
received wisdom Linux-ism rather than a well documented one). As
working around would add more hard to test complexity to the test I've
gone for the easier option of making it CONFIG_LINUX only.

Hmm.  I got reports of this issue and tried to reproduce, but I was
never able to.  I thought I had fixed it via other means, but I had no
idea this was the cause of the issue.

It's not a Linux-ism, I don't think, Richard Steven's "Unix Network
Programming" mentions that is how this works (at least on UDP), and that
is pre-Linux.  That's probably where I got this technique.  I've saw
some web pages mention that Solaris and Windows do it this way.

However, it's not specified, so it's probably a bad idea.  The only way
I can think to do it another way is to remove the bind() call, then it
should randomly assign the port (per the spec, I think).  The trouble
with that is the address will be INADDR_ANY, so it will be bound on
other interfaces besides the loopback, which make me slightly worried
from a security point of view.

I'm ok with this being linux-only, but I'd like to fix it so it works
everywhere.

The other option is to keep the bind but seed it ourselves with a random
port. However then you need to loop until you succeed and avoid locking
up if something fatal has gone wrong.

One option could be to use the glib networking stuff to set this up.
That has options for creating dynamic ports for incoming connections
although the docs are a bit light on details.
g_socket_listener_add_any_inet_port certainly seems to do the retry
approach (for a weirdly arbitrary 37 times). It leaves the fancy stuff
to a hopefully well tested library although I note QEMU's own use of
g_io APIs seems to be pretty sporadic.

[PATCH v1 6/6] tests/vm: support sites with sha512 checksums

This is unrelated to your NetBSD update in this series -- it's
one of the persistent intermittents I see on the BSDs:
https://lore.kernel.org/qemu-devel/20190916153312.GD25552@stefanha-x1.localdomain/t/

(though the failure rate I see is I think <20%, but I haven't
really carefully measured it.)

Does this patch rely on AIO API in the kernel? If so than this is
unreliable as of today on NetBSD. We plan to fix it, but there is no
expected time of accomplishment.

No, we use our own AIO implementation which puts fds into non-blocking
mode and uses a thread which polls them to identify when they're
ready to actually perform IO (plus a lot of coroutine magic).
