39ce923732 gitlab: enable a very minimal build with the tricore container
Rather than base of the shared Debian 10 container which would require
us to bring in even more dependencies just bring in what is needed for
building tricore-softmmu in GitLab. We don't even remove the container
from the DOCKER_PARTIAL_IMAGES lest we cause more confusion.

c56f1ee668 tests/tcg/configure.sh: add handling for assembler only builds
Up until this point we only handled local compilers or assumed we had
everything in the container. This falls down when we are building QEMU
inside the container.

This special handling only affects tricore for now but I put it in a
case just in case we add any other "special" targets. Setting
CROSS_CC_GUEST is a bit of a hack just to ensure the test runs as we
gate on a detected compiler even though the Makefile won't actually
use it. It also means we display something sane in the configure
output.

18fa3ebc45 qapi: introduce forwarding visitor
This new adaptor visitor takes a single field of the adaptee, and exposes it
with a different name.

This will be used for QOM alias properties.  Alias targets can of course
have a different name than the alias property itself (e.g. a machine's
pflash0 might be an alias of a property named 'drive').  When the target's
getter or setter invokes the visitor, it will use a different name than
what the caller expects, and the visitor will not be able to find it
(or will consume erroneously).

The solution is for alias getters and setters to wrap the incoming
visitor, and forward the sole field that the target is expecting while
renaming it appropriately.

955171e441 qemu-img: Add --skip-broken-bitmaps for 'convert --bitmaps'
The point of 'qemu-img convert --bitmaps' is to be a convenience for
actions that are already possible through a string of smaller
'qemu-img bitmap' sub-commands.  One situation not accounted for
already is that if a source image contains an inconsistent bitmap (for
example, because a qemu process died abruptly before flushing bitmap
state), the user MUST delete those inconsistent bitmaps before
anything else useful can be done with the image.

We don't want to delete inconsistent bitmaps by default: although a
corrupt bitmap is only a loss of optimization rather than a corruption
of user-visible data, it is still nice to require the user to opt in
to the fact that they are aware of the loss of the bitmap.  Still,
requiring the user to check 'qemu-img info' to see whether bitmaps are
consistent, then use 'qemu-img bitmap --remove' to remove offenders,
all before using 'qemu-img convert', is a lot more work than just
adding a knob 'qemu-img convert --bitmaps --skip-broken-bitmaps' which
opts in to skipping the broken bitmaps.

After testing the new option, also demonstrate the way to manually fix
things (either deleting bad bitmaps, or re-creating them as empty) so
that it is possible to convert without the option.

74a4320f30 qemu-img: Fail fast on convert --bitmaps with inconsistent bitmap
Waiting until the end of the convert operation (a potentially
time-consuming task) to finally detect that we can't copy a bitmap is
bad, comparing to failing fast up front.  Furthermore, this prevents
us from leaving a file behind with a bitmap that is not marked as
inconsistent even though it does not have sane contents.

This fixes the problems exposed in the previous patch to the iotest:
it adds a fast failure up front, and even if we don't fail early, it
ensures that any bitmap we add but do not properly populate is removed
again rather than left behind incomplete.

94075c28ee iotests: Improve and rename test 291 to qemu-img-bitmap
Enhance the test to demonstrate existing less-than-stellar behavior of
qemu-img with a qcow2 image containing an inconsistent bitmap: we
don't diagnose the problem until after copying the entire image (a
potentially long time), and when we do diagnose the failure, we still
end up leaving an empty bitmap in the destination.  This mess will be
cleaned up in the next patch.

While at it, rename the test now that we support useful iotest names,
and fix a missing newline in the error message thus exposed.

d44dae1a7c block/mirror: fix active mirror dead-lock in mirror_wait_on_conflicts
It's possible that requests start to wait each other in
mirror_wait_on_conflicts(). To avoid it let's use same technique as in
block/io.c in bdrv_wait_serialising_requests_locked() /
bdrv_find_conflicting_request(): don't wait on intersecting request if
it is already waiting for some other request.

For details of the dead-lock look at testIntersectingActiveIO()
test-case which we actually fixing now.

e0f69d83d5 iotest 151: add test-case that shows active mirror dead-lock
There is a dead-lock in active mirror: when we have parallel
intersecting requests (note that non intersecting requests may be
considered intersecting after aligning to mirror granularity), it may
happen that request A waits request B in mirror_wait_on_conflicts() and
request B waits for A.

Look at the test for details. Test now dead-locks, that's why it's
disabled. Next commit will fix mirror and enable the test.

a0c7b99bf7 qapi: Fix crash on missing enum member name
New test case enum-dict-no-name.json crashes:

    $ python3 scripts/qapi-gen.py tests/qapi-schema/enum-dict-no-name.json
    Traceback (most recent call last):
    [...]
      File "/work/armbru/qemu/scripts/qapi/expr.py", line 458, in check_enum
	member_name = member['name']
    KeyError: 'name'

Root cause: we try to retrieve member 'name' before we check for
missing members.  With that fixed, we get the expected error "'data'
member misses key 'name'".

e2bcd3ad09 tests/tcg: make test-mmap a little less aggressive
The check_aligned_anonymous_unfixed_mmaps and
check_aligned_anonymous_unfixed_colliding_mmaps do a lot of mmap's and
copying of data. This is especially unfriendly to targets like hexagon
which have quite large pages and need to do sanity checks on each
memory access.

While we are at it clean-up the white space and style issues from the
legacy code. As we no longer do quite so much needless memory access
we can also remove the hexagon timeout hack.

librados-dev is not required by QEMU directly, only librbd-dev.

glusterfs-common is not directly needed by QEMU.

QEMU uses ncursesw only on non-Windows hosts.

The clang package is clang 10.

flex and bison are not required by QEMU.

Standardize on nmap ncat implementation to match Fedora/CentOS.

Remove vim since it is not a build pre-requisite and no other containers
include it.

888673bbb9 tests/docker: remove FEATURES env var from templates
In preparation for switching to auto-generated dockerfiles, remove the
FEATURES env variable. The equivalent functionality can be achieved in

The cases which don't correspond to binaries are simply dropped because
configure/meson will probe for any requested feature anyway.

1ae2786c7c tests/docker: use explicit docker.io registry
It is good practice to use an explicit registry for referencing the base
image. This is because some distros will inject their own registries
into the search path. For example registry.fedoraproject.org comes ahead
of docker.io. Using an explicit registry avoids wasting time querying
multiple registries for images that they won't have.

102cd5c294 tests/docker: use project specific container registries
Since Docker Hub has started to enforce pull rate limits on clients, it
is preferrable to use project specific container registries where they
are available. Fedora and OpenSUSE projects provide registries.

The images in these registries are also refreshed on a more regular
basis than the ones in docker hub, so the package update should
generally be faster.

While CentOS also has a registry it is considerably outdated compared
to docker.io, and also only provides x86 images, while docker.io images
are multi-arch.

927fae0eb9 tests/migration: fix unix socket migration
The test aborts and error message as the following be throwed:
"No such file or directory: '/var/tmp/qemu-migrate-{pid}.migrate",
when the unix socket migration test nearly done. The reason is
qemu removes the unix socket file after migration before
guestperf.py script do it. So pre-check if the socket file exists
when removing it to prevent the guestperf program from aborting.

See also commit f9cc00346d ("tests/migration: fix unix socket batch
migration").

83bee4b51f crypto: replace 'des-rfb' cipher with 'des'
Currently the crypto layer exposes support for a 'des-rfb'
algorithm which is just normal single-DES, with the bits
in each key byte reversed. This special key munging is
required by the RFB protocol password authentication
mechanism.

Since the crypto layer is generic shared code, it makes
more sense to do the key byte munging in the VNC server
code, and expose normal single-DES support.

Replacing cipher 'des-rfb' by 'des' looks like an incompatible
interface change, but it doesn't matter.  While the QMP schema
allows any QCryptoCipherAlgorithm for the 'cipher-alg' field
in QCryptoBlockCreateOptionsLUKS, the code restricts what can
be used at runtime. Thus the only effect is a change in error
message.

Original behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-rfb
 qemu-img: demo.luks: Algorithm 'des-rfb' not supported

New behaviour:

 $ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
 Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-fish
 qemu-img: demo.luks: Invalid parameter 'des-rfb'

f8157e100c crypto: add crypto tests for single block DES-ECB and DES-CBC
The GNUTLS crypto provider doesn't support DES-ECB, only DES-CBC.
We can use the latter to simulate the former, if we encrypt only
1 block (8 bytes) of data at a time, using an all-zeros IV. This
is a very inefficient way to use the QCryptoCipher APIs, but
since the VNC authentication challenge is only 16 bytes, this
is acceptable. No other part of QEMU should be using DES. This
test case demonstrates the equivalence of ECB and CBC for the
single-block case.
