  ipmi:smbus: Add a check around a memcpy

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

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.

  hw/nvme: do not enable ioeventfd by default
  hw/nvme: unregister the event notifier handler on the main loop
  hw/nvme: skip queue processing if notifier is cleared

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

In one case:

  memcpy(sid->inmsg + sid->inlen, buf, len);

if len == 0 then sid->inmsg + sig->inlen can point to one past the inmsg
array if the array is full.  We have to allow len == 0 due to some
vagueness in the spec, but we don't have to call memcpy.

Found by Coverity.  This is not a problem in practice, but the results
are technically (maybe) undefined.  So make Coverity happy.

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

How to control the booting of QEMU is often a source of confusion for
users. Bring the options that control this together in the manual
pages and add some verbiage to describe when each option is
appropriate. This attempts to codify some of the knowledge expressed

Currently QEMU exits with code 0 on both panic an shutdown. For tests
it is useful to return 1 on panic, so that it counts as a test
failure.

Introduce a new exit-failure PanicAction that makes main() return
EXIT_FAILURE. Tests can use -action panic=exit-failure option to
activate this behavior.

The TARGET_SYS_TMPNAM implementation has two bugs spotted by
Coverity:
 * confusion about whether 'len' has the length of the string
   including or excluding the terminating NUL means we
   lock_user() len bytes of memory but memcpy() len + 1 bytes
 * In the error-exit cases we forget to free() the buffer
   that asprintf() returned to us

The SET_ARG() macro returns an error indication; we check this in the
TARGET_SYS_GET_CMDLINE case but not when we use it in implementing
TARGET_SYS_ELAPSED.  Check for and handle the errors via the do_fault
codepath, and update the comment documenting the SET_ARG() and
GET_ARG() macros to note how they handle memory access errors.

The console_write() semihosting function outputs guest data from a
buffer; it doesn't update that buffer.  It therefore doesn't need to
pass a length value to unlock_user(), but can pass 0, meaning "do not
copy any data back to the guest memory".

The documentation comment for qemu_semihosting_console_write() says
 * Returns: number of bytes written -- this should only ever be short
 * on some sort of i/o error.

and the callsites rely on this.  However, the implementation code
path which sends console output to a chardev doesn't honour this,
and will return negative values on error.  Bring it into line with
the other implementation codepaths and the documentation, so that
it returns 0 on error.

Spotted by Coverity, because console_write() passes the return value
to unlock_user(), which doesn't accept a negative length.

The following error message was seen during the configure:

  "ln: failed to create symbolic link
  'x86_64-softmmu/qemu-system-x86_64.exe': No such file or directory"

By default the MSYS environment variable is not defined, so the runtime
behavior of winsymlinks is: if <target> does not exist, 'ln -s' fails.
At the configure phase, the qemu-system-x86_64.exe has not been built
so creation of the symbolic link fails hence the error message.

Set winsymlinks to 'native' whose behavior is most similar to the
behavior of 'ln -s' on *nix, that is:

  a) if native symlinks are enabled, and whether <target> exists
     or not, creates <destination> as a native Windows symlink;
  b) else if native symlinks are not enabled, and whether <target>
     exists or not, 'ln -s' creates as a Windows shortcut file.

At present winsymlinks is set to 'nativestrict', and its behavior is:

This causes the following error message was seen during the configure:

  "ln: failed to create symbolic link

Change winsymlinks to 'native' whose behavior is most similar to the

When tests fail meson just displays a summary and tells you to look at
the testlog.txt file for details. The native jobs on shared runners
publish testlog.txt as an artifact. For the Cirrus jobs and custom
runner jobs this is not currently possible. The best we can do is cat
the log contents on failure, to give maintainers a fighting chance
of diagnosing the problem.

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

probe_target_compiler returns nonempty $target_cc for installed toolchains
and $container_cross_cc for container-based toolchains.  In both cases
however the flags (coming from $cross_cc_cflags_${target_arch}) must be
in $target_cflags.

Therefore, do not clear them prior to returning from probe_target_compiler.

perror() is designed to append the decoded errno value to a
string. This, however, only makes sense if we called something that
actually sets errno prior to that.

For the callers that check for split irqchip support that is not the
case, and we end up with confusing error messages that end in
"success". Use error_report() instead.
