58f7db26f2 KVM: x86: workaround invalid CPUID[0xD,9] info on some AMD processors
Some AMD processors expose the PKRU extended save state even if they do not have
the related PKU feature in CPUID.  Worse, when they do they report a size of
64, whereas the expected size of the PKRU extended save state is 8, therefore
the esa->size == eax assertion does not hold.

The state is already ignored by KVM_GET_SUPPORTED_CPUID because it
was not enabled in the host XCR0.  However, QEMU kvm_cpu_xsave_init()
runs before QEMU invokes arch_prctl() to enable dynamically-enabled
save states such as XTILEDATA, and KVM_GET_SUPPORTED_CPUID hides save
states that have yet to be enabled.  Therefore, kvm_cpu_xsave_init()
needs to consult the host CPUID instead of KVM_GET_SUPPORTED_CPUID,
and dies with an assertion failure.

When setting up the ExtSaveArea array to match the host, ignore features that
KVM does not report as supported.  This will cause QEMU to skip the incorrect
CPUID leaf instead of tripping the assertion.

cb48748af7 i386: Set MCG_STATUS_RIPV bit for mce SRAR error
In the physical machine environment, when a SRAR error occurs,
the IA32_MCG_STATUS RIPV bit is set, but qemu does not set this
bit. When qemu injects an SRAR error into virtual machine, the
virtual machine kernel just call do_machine_check() to kill the
current task, but not call memory_failure() to isolate the faulty
page, which will cause the faulty page to be allocated and used
repeatedly. If used by the virtual machine kernel, it will cause
the virtual machine to crash

0f37cf2f71 docs/tcg-plugins: document QEMU_PLUGIN behaviour
QEMU plugins can be loaded via command line arguments or via
the QEMU_PLUGIN environment variable. Currently, only the first method
is documented. Let's document QEMU_PLUGIN.

As drive-by cleanup, this patch fixes the path to the plugins
in the same section of the documentation.

309df6acb2 gitlab: disable accelerated zlib for s390x
There appears to be a bug in the s390 hardware-accelerated version of
zlib distributed with Ubuntu 20.04, which makes our test
/i386/migration/multifd/tcp/zlib hit an assertion perhaps one time in
10. Fortunately zlib provides an escape hatch where we can disable the
hardware-acceleration entirely by setting the environment variable
DFLTCC to 0. Do this on all our CI which runs on s390 hosts, both our
custom gitlab runner and also the Travis hosts.

80f0fe3a85 linux-user: Fix syscall parameter handling for MIPS n32
The MIPS n32 ABI is basically n64 with the address space (i.e. pointer
width) shrinked to 32 bits. Meanwhile the current code treats it as
o32-like based on TARGET_ABI_BITS, which causes problems with n32
syscalls utilizing 64-bit offsets, like pread64, affecting most (if not
all) recently built n32 binaries.

This partially solves issue #909 ("qemu-mipsn32(el) user mode emulator
fails to execute any recently built n32 binaries"); with this change
applied, the built qemu-mipsn32el is able to progress beyond the
pread64, and finish _dl_start_user for the "getting ld.so load libc.so"
case. The program later dies with SIGBUS, though, due to _dl_start_user
not maintaining stack alignment after removing ld.so itself from argv,
and qemu-user starting to enforce alignment recently, but that is
orthogonal to the issue here; the more common case of chrooting is
working, verified with my own-built Gentoo n32 sysroot. (Depending on
the exact ISA used, one may have to explicitly specify QEMU_CPU, which
is the case for my chroot.)

48f1fcd5c8 iotests/207: Filter host fingerprint
Commit e3296cc796 made the ssh block
driver's error message for fingerprint mismatches more verbose, so it
now prints the actual host key fingerprint and the key type.

iotest 207 tests such errors, but was not amended to filter that
fingerprint (which is host-specific), so do it now.  Filter the key
type, too, because I guess this too can differ depending on the host
configuration.

da9d88d8e6 iotests.py: Filters for VM.run_job()
Allow filters for VM.run_job(), and pass the filters given to
VM.blockdev_create() to it.

(Use this opportunity to annotate VM.run_job()'s parameter types;
unfortunately, for the filter, I could not come up with anything better
than Callable[[Any], Any] that would pass mypy's scrutiny.)

At one point, a plain string is logged, so the filters passed to it must
work fine with plain strings.  The only filters passed to it at this
point are the ones from VM.blockdev_create(), which are
filter_qmp_test_files() (by default) and 207's filter_hash().  Both
cannot handle plain strings yet, but we can make them by amending
filter_qmp() to treat them as plain values with a None key.

8f685ac391 iotests: make qemu_img_log and img_info_log raise on error
Add a `check: bool = True` parameter to both functions and make their
qemu_img() invocations raise on error by default.

users of img_info_log:
206, 207, 210, 211, 212, 213, 237, 242, 266, 274, 302

users of qemu_img_log:
044, 209, 274, 302, 304

iotests 242 and 266 need to use check=False for their negative tests.
iotests 206, 210, 211, 212, 213, 237, 274 and 302 continue working
normally.

As of this commit, all calls to QEMU_IMG made from iotests enforce a
return code of zero by default unless explicitly disabled or suppressed
by passing check=False or with an exception handler.

With the exceptional 'create' calls removed in the prior commit, change
qemu_img_log() and img_info_log() to call qemu_img() directly

For now, allow these calls to qemu-img to return non-zero on the basis
that any unusual output will be logged anyway. The very next commit
begins to enforce a successful exit code by default even for the logged
functions.
