6a54ac2a97 tests/unit: fix a -Wformat-truncation warning
../tests/test-qobject-input-visitor.c: In function ‘test_visitor_in_list’:

Rather than trying to be clever, since this is called 3 times during
tests, let's simply use g_strdup_printf().

10dcb08b03 target/loongarch: Remove cpu_fcsr0
All of the fpu operations are defined with TCG_CALL_NO_WG, but they
all modify FCSR0.  The most efficient way to fix this is to remove
cpu_fcsr0, and instead use explicit load and store operations for the
two instructions that manipulate that value.

1bca64a3f0 tests/qtest/migration-test: Run the dirty ring tests only with the x86 target
kvm_dirty_ring_supported() only checks whether the dirty ring support
is available on the x86 host, but it ignores whether the target QEMU
architecture is x86 or not. Thus the test_vcpu_dirty_limit() test
currently fails with the assert((strcmp(arch, "x86_64") == 0)) statement
in dirtylimit_start_vm() if the users run e.g. "make check-qtest-aarch64"
on their x86 host. Fix it by only executing the tests when we're running
with a x86_64 target QEMU binary with KVM.

Thomas reported that auto-converge test will timeout on MacOS CI gatings.
Use the migrate_ensure_converge() helper too in the auto-converge as when
Daniel reworked the other test cases.

Since both max_bandwidth / downtime_limit will not be used for converge
calculations, make it simple by removing the remaining check, then we can
completely remove both variables altogether, since migrate_ensure_converge
is used the remaining check won't make much sense anyway.

test_socket hangs randomly in connect(), especially when run without

feb6cb9369 tests: refresh to latest libvirt-ci module
Notable changes:

  - libvirt-ci source tree was re-arranged, so the script we
    run now lives in a bin/ sub-dir

  - opensuse 15.2 is replaced by opensuse 15.3

  - libslirp is temporarily dropped on opensuse as the
    libslirp-version.h is broken

     https://bugzilla.opensuse.org/show_bug.cgi?id=1201551

  - The incorrectly named python3-virtualenv module was
    changed to python3-venv, but most distros don't need
    any package as 'venv' is a standard part of python

  - glibc-static was renamed to libc-static, to reflect
    fact that it isn't going to be glibc on all distros

  - The cmocka/json-c deps that were manually added to
    the centos dockerfile and are now consistently added
    to all targets

15fc6badbd Hexagon (target/hexagon) fix bug in mem_noshuf load exception
The semantics of a mem_noshuf packet are that the store effectively
happens before the load.  However, in cases where the load raises an
exception, we cannot simply execute the store first.

This change adds a probe to check that the load will not raise an
exception before executing the store.

If the load is predicated, this requires special handling.  We check
the condition before performing the probe.  Since, we need the EA to
perform the check, we move the GET_EA portion inside CHECK_NOSHUF_PRED.

Test case added in tests/tcg/hexagon/mem_noshuf_exception.c

cab86dea1d Hexagon (target/hexagon) fix store w/mem_noshuf & predicated load
Call the CHECK_NOSHUF macro multiple times: once in the
fGEN_TCG_PRED_LOAD() and again in fLOAD().

Before this commit, a packet with a store and a predicated
load with mem_noshuf that gets encoded like this:

    { P0 = cmp.eq(R17,#0x0)
      memw(R18+#0x0) = R2
      if (!P0.new) R3 = memw(R17+#0x4) }

... would end up generating a branch over both the load
and the store like so:

    ...
    brcond_i32 loc17,$0x0,eq,$L1
    mov_i32 loc18,store_addr_1
    qemu_st_i32 store_val32_1,store_addr_1,leul,0

c4f8ce24de tests/unit: Replace g_memdup() by g_memdup2()
Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538

  The old API took the size of the memory to duplicate as a guint,
  whereas most memory functions take memory sizes as a gsize. This
  made it easy to accidentally pass a gsize to g_memdup(). For large
  values, that would lead to a silent truncation of the size from 64
  to 32 bits, and result in a heap area being returned which is
  significantly smaller than what the caller expects. This can likely
  be exploited in various modules to cause a heap buffer overflow.

Replace g_memdup() by the safer g_memdup2() wrapper.

The fedora container has since been split apart, so there's no suitable
nearby target that would support "test-mingw" as it requires both x32

eaf46a65ab tests/vm: add 1GB extra memory per core
If you try to run a 16 or 32 threaded test, you're going to run out of
memory very quickly with qom-test and a few others. Bump the memory
limit to try to scale with larger-core machines.

Granted, this means that a 16 core processor is going to ask for 16GB,
but you *probably* meet that requirement if you have such a machine.

512MB per core didn't seem to be enough to avoid ENOMEM and SIGABRTs in
the test cases in practice on a six core machine; so I bumped it up to
1GB which seemed to help.

Add this magic in early to the configuration process so that the
config file, if provided, can still override it.

This is listed twice by accident; we require genisoimage to run the
test, so remove the unconditional entry.

5e658729b6 tests/vm: remove ubuntu.i386 VM test
Ubuntu 18.04 is out of our support window, and Ubuntu 20.04 does not
support i386 anymore. The debian project does, but they do not provide
any cloud images for it, a new expect-style script would have to be
written.

Since we have i386 cross-compiler tests hosted on GitLab CI, we don't
need to support this VM test anymore.

47f71f8912 tests/vm: upgrade Ubuntu 18.04 VM to 20.04
18.04 has fallen out of our support window, so move ubuntu.aarch64
forward to ubuntu 20.04, which is now our oldest supported Ubuntu
release.

Notes:

This checksum changes periodically; use a fixed point image with a known
checksum so that the image isn't re-downloaded on every single
invocation. (The checksum for the 18.04 image was already incorrect at
the time of writing.)

Just like the centos.aarch64 test, this test currently seems very
flaky when run as a TCG test.

5d8e7da891 tests/vm: switch centos.aarch64 to CentOS 8 Stream
Switch this test over to using a cloud image like the base CentOS8 VM
test, which helps make this script a bit simpler too.

Note: At time of writing, this test seems pretty flaky when run without
KVM support for aarch64. Certain unit tests like migration-test,
virtio-net-failover, test-hmp and qom-test seem quite prone to fail
under TCG. Still, this is an improvement in that at least pure build
tests are functional.

The old CentOS image didn't work anymore because it was already EOL at
the beginning of 2022.

1ab330eae5 tests/vm: use 'cp' instead of 'ln' for temporary vm images
If the initial setup fails, you've permanently altered the state of the
downloaded image in an unknowable way. Use 'cp' like our other test
setup scripts do.
