afa1cf4329 docker: remove unused debian8 partial image
debian8 partial base is also not consumed by any image, so remove it.
For QEMU's development cycle, we only support debian9 (stretch) and
debian10 (buster).

b9fe0063b7 tests/tcg: add simple record/replay smoke test for aarch64
This adds two new tests that re-use the memory test to check basic
record replay functionality is still working. We have to define our
own runners rather than using the default pattern as we want to change
the test name but re-use the memory binary.

We declare the test binaries as PHONY as they don't really exist.

[AJB: A better test would output some sort of timer value or other
otherwise variable value so we could compare the record and replay
outputs and ensure they match]

b059a62bb6 tests/tcg: add generic version of float_convs
This is broadly similar to the existing fcvt test for ARM but using
the generic float testing framework. We should be able to pare down
the ARM fcvt test case to purely half-precision with or without the
Alt HP provision.

a4f3ed629e tests/tcg: add float_madds test to multiarch
This is a generic floating point multiply and accumulate test for
single precision floating point values. I've split of the common float
functions into a helper library so additional tests can use the same
common code.

As I don't have references for all architectures I've allowed some
flexibility for tests to pass without reference files. They can be
added as we get collect them.

There was in the clean-up code caused by attempting to inspect images
which finished before we got there. Clean up the clean up code by:

  - only track the one instance at a time
  - use --filter for docker ps instead of doing it by hand
  - just call docker rm -f to be done with it
  - use uuid.uuid4() for a random uid

1b5c15cebd nbd/client: Add hint when TLS is missing
I received an off-list report of failure to connect to an NBD server
expecting an x509 certificate, when the client was attempting something
similar to this command line:

$ ./x86_64-softmmu/qemu-system-x86_64 -name 'blah' -machine q35 -nodefaults \
  -object tls-creds-x509,id=tls0,endpoint=client,dir=$path_to_certs \
  -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pcie.0,addr=0x6 \
  -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0 \
  -device scsi-hd,id=image1,drive=drive_image1,bootindex=0
qemu-system-x86_64: -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0: TLS negotiation required before option 7 (go)
server reported: Option 0x7 not permitted before TLS

The problem?  As specified, -drive is trying to pass tls-creds to the
raw format driver instead of the nbd protocol driver, but before we
get to the point where we can detect that raw doesn't know what to do
with tls-creds, the nbd driver has already failed because the server
complained.  The fix to the broken command line?  Pass
'...,file.tls-creds=tls0' to ensure the tls-creds option is handed to
nbd, not raw.  But since the error message was rather cryptic, I'm
trying to improve the error message.

With this patch, the error message adds a line:

qemu-system-x86_64: -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0: TLS negotiation required before option 7 (go)
Did you forget a valid tls-creds?
server reported: Option 0x7 not permitted before TLS

And with luck, someone grepping for that error message will find this
commit message and figure out their command line mistake.  Sadly, the
only mention of file.tls-creds in our docs relates to an --image-opts
use of PSK encryption with qemu-img as the client, rather than x509
certificate encryption with qemu-kvm as the client.

887a2069f7 qapi: Fix broken discriminator error messages
check_union() checks the discriminator exists in base and makes sense.
Two error messages mention the base.  These are broken for anonymous
bases, as demonstrated by tests flat-union-invalid-discriminator and
flat-union-invalid-if-discriminator.err.  The third one doesn't
bother.

First broken when commit ac4338f8eb "qapi: Allow anonymous base for
flat union" (v2.6.0) neglected to adjust the "not a member of base"
error message.  Commit ccadd6bcba "qapi: Add 'if' to implicit struct
members" (v4.0.0) then cloned the flawed error message.

Dumb them down not to mention the base.

9d55380b5a qapi: Remove null from schema language
We represent the parse tree as OrderedDict.  We fetch optional dict
members with .get().  So far, so good.

We represent null literals as None.  .get() returns None both for
"absent" and for "present, value is the null literal".  Uh-oh.

Test features-if-invalid exposes this bug: "'if': null" is
misinterpreted as absent "if".

We added null to the schema language to "allow [...] an explicit
default value" (commit e53188ada5 "qapi: Allow true, false and null in
schema json", v2.4.0).  Hasn't happened; null is still unused except
as generic invalid value in tests/.

To fix, we'd have to replace .get() by something more careful, or
represent null differently.  Feasible, but we got more and bigger fish
to fry right now.  Remove the null literal from the schema language.
Replace null in tests by another invalid value.

Test features-if-invalid now behaves as it should.

cd346bdc46 tests/qapi-schema: Demonstrate misleading optional tag error
Test flat-union-optional-discriminator declares its union tag as
'*switch': 'Enum', and points to it with 'discriminator': '*switch'.
This gets rejected as "discriminator of flat union 'MyUnion' uses
invalid name '*switch'".  Correct; member 'discriminator' doesn't
accept a '*' prefix.

However, this merely tests name validity checking, which we already
cover elsewhere.  More interesting is testing the valid name 'switch'.
This reports "discriminator 'switch' is not a member of base struct
'Base'", which is misleading.

Copy the existing 'discriminator': '*switch' test to
flat-union-discriminator-bad-name, and rewrite its comment.  Change
flat-union-optional-discriminator to test 'discriminator': 'switch',
and mark it FIXME.

Absent flat union branches default to the empty struct (since commit

A union or alternate without branches makes no sense and doesn't work:
it can't be instantiated.  A union or alternate with just one branch
works, but is degenerate.  We accept the former, but reject the
latter.  Weird.  docs/devel/qapi-code-gen.txt doesn't mention the
difference.  It claims an alternate definition is "is similar to a
simple union type".

The QAPI schema parser accepts both less and more than JSON: it
accepts only ASCII with \u (less), and accepts control characters
other than LF (new line) unescaped.  How it treats unescaped non-ASCII
input differs between Python 2 and Python 3.

Make it accept strictly less: require printable ASCII.  Drop support

b22e86585b qapi: Drop support for boxed alternate arguments
Commands and events can define their argument type inline (default) or
by referring to another type ('boxed': true, since commit c818408e44
"qapi: Implement boxed types for commands/events", v2.7.0).  The
unboxed inline definition is an (anonymous) struct type.  The boxed
type may be a struct, union, or alternate type.

The latter is problematic: docs/interop/qemu-spec.txt requires the
value of the 'data' key to be a json-object, but any non-degenerate
alternate type has at least one branch that isn't.

Fortunately, we haven't made use of alternates in this context outside
tests/.  Drop support for them.

QAPISchemaAlternateType.is_empty() is now unused.  Drop it, too.

This replaces paramiko with avocado.utils.ssh module, which is based
on a (open)ssh binary, supposedly more ubiquitous.

07d647b261 tests/acceptance: Refactor and improve reporting in linux_ssh_mips_malta.py
This patch restructures code organization around the test case
executions. At the same time, rather than outputing a cryptic message:

FAIL: True not found in [False],

the following will be reported too, if the command output does not meet
specified expectations:

'lspci -d 11ab:4620' output doesn't contain the word 'GT-64120'

7219c2e842 Acceptance test x86_cpu_model_versions: split into smaller tests
The justifications being automatic destruction of the vm instances
when no longer needed and more compact test naming under a common
class.

Besides those, a smaller test makes the one and only assertion rather
obvious, which suggests that we could even get rid of the more verbose
(and manual) error messages (to be decided).

Naming of the tests tries to follow the following pattern:

 test_($cpu_version)_($no_arch_capabitilies_set_or_unset)_($machine_version)

The presence of each naming component is optional, depending on
whether the test manually sets it or not.
