I have no objection to having Slirp code in QEMU be licensed under
the 3-clause BSD license.
slirp/COPYRIGHT's initial version in 2004 (commit 5fafdf24) listed
only 3 clauses BUT used the poisonous advertising clause for clause 3
which is the controversial clause of non-free 4-clause (that is, it
appears that the BSD-4 license was copied, and then the WRONG clause
was deleted, when creating COPYRIGHT. Perhaps explained as an easy
mistake to make since 3-clause was created by removing clause 3 of the
4-clause, where you sometimes see the three-clause version with
clauses 1, 2, 4; but more commonly see a renumbered version with
clauses 1, 2, 3 to close the gap. If you pay attention only to clause
numbers instead of content, it can be easy to confuse which clause to
delete to go from 4-clause to 3-clause).
Commit 2f5f89963 removed the poisonous wrong clause on
the grounds of moving from 4-clause to 3-clause; but did not add the
missing clause, which makes it LOOK like the 2-clause version. But I
think we have a decent enough trail showing the intent for 3-clause.

This happens because OSPKE was never returned by
GET_SUPPORTED_CPUID or x86_cpu_get_supported_feature_word().
OSPKE is a runtime flag automatically set by the KVM module or by
TCG code, was always cleared by x86_cpu_filter_features(), and
was not supposed to appear on the CPU model table.
Remove the OSPKE flag from the CPU model table entries, to avoid
the bogus warning and avoid returning invalid feature data on
query-cpu-* QMP commands. As OSPKE was always cleared by
x86_cpu_filter_features(), this won't have any guest-visible
impact.
Include a test case that should detect the problem if we introduce
a similar bug again.

i386: kvm: Disable arch_capabilities if MSR can't be set
KVM has two bugs in the handling of MSR_IA32_ARCH_CAPABILITIES:
1) Linux commit commit 1eaafe91a0df ("kvm: x86: IA32_ARCH_CAPABILITIES
is always supported") makes GET_SUPPORTED_CPUID return
arch_capabilities even if running on SVM. This makes "-cpu
host,migratable=off" incorrectly expose arch_capabilities on CPUID on
AMD hosts (where the MSR is not emulated by KVM).
2) KVM_GET_MSR_INDEX_LIST does not return MSR_IA32_ARCH_CAPABILITIES if
the MSR is not supported by the host CPU. This makes QEMU not
initialize the MSR properly at kvm_put_msrs() on those hosts.
Work around both bugs on the QEMU side, by checking if the MSR
was returned by KVM_GET_MSR_INDEX_LIST before returning the
feature flag on kvm_arch_get_supported_cpuid().
This has the unfortunate side effect of making arch_capabilities
unavailable on hosts without hardware support for the MSR until bug #2
is fixed on KVM, but I can't see another way to work around bug #1
without that side effect.

mirror: Confirm we're quiesced only if the job is paused or cancelled
While child_job_drained_begin() calls to job_pause(), the job doesn't
actually transition between states until it runs again and reaches a
pause point. This means bdrv_drained_begin() may return with some jobs
using the node still having 'busy == true'.
As a consequence, block_job_detach_aio_context() may get into a
deadlock, waiting for the job to be actually paused, while the coroutine
servicing the job is yielding and doesn't get the opportunity to get
scheduled again. This situation can be reproduced by issuing a
'block-commit' immediately followed by a 'device_del'.
To ensure bdrv_drained_begin() only returns when the jobs have been
paused, we change mirror_drained_poll() to only confirm it's quiesced
when job->paused == true and there aren't any in-flight requests, except
if we reached that point by a drained section initiated by the
mirror/commit job itself.
The other block jobs shouldn't need any changes, as the default

RISC-V Patches for 4.0-rc0, Part 2
This patch set contains three major sources of bug fixes:
* Jim has added support for GDB XML files, as well as fixing access to
CSRs via the GDB stub.
* Alistair has rebased a large set of fixes from Michael that were still
in his patch queue. These fix bugs all over our tree, including:
* Logging of PMP errors.
* User ABI cleanups and fixes, most notably on RVE guests.
* Fixes for interrupt emulation fidelity.
* Improvements to the emulation fidelity of the sifive_u machine.
* Bin Meng has improved the emulation fidelity of the SiFive UART, which
now supports both TX and RX interrupts (as well as setting the correct
interrupt line).

RISC-V: Add support for vectored interrupts
If vectored interrupts are enabled (bits[1:0]
of mtvec/stvec == 1) then use the following
logic for trap entry address calculation:
pc = mtvec + cause * 4
In addition to adding support for vectored interrupts
this patch simplifies the interrupt delivery logic
by making sync/async cause decoding and encoding
steps distinct.
The cause code and the sign bit indicating sync/async
is split at the beginning of the function and fixed
cause is renamed to cause. The MSB setting for async
traps is delayed until setting mcause/scause to allow
redundant variables to be eliminated. Some variables
are renamed for conciseness and moved so that decls
are at the start of the block.

RISC-V: Allow interrupt controllers to claim interrupts
We can't allow the supervisor to control SEIP as this would allow the
supervisor to clear a pending external interrupt which will result in
lost a interrupt in the case a PLIC is attached. The SEIP bit must be
hardware controlled when a PLIC is attached.
This logic was previously hard-coded so SEIP was always masked even
if no PLIC was attached. This patch adds riscv_cpu_claim_interrupts
so that the PLIC can register control of SEIP. In the case of models
without a PLIC (spike), the SEIP bit remains software controlled.
This interface allows for hardware control of supervisor timer and
software interrupts by other interrupt controller models.

spapr: Correctly set LPCR[GTSE] in H_REGISTER_PROCESS_TABLE
176dccee "target/ppc/spapr: Clear partition table entry when allocating

unfortunately due to a small error no longer correctly sets the LPCR[GTSE]
bit which allows the guest to directly execute (some types of) tlbie (TLB
flush) instructions without involving the hypervisor.
We got away with this, initially, because POWER9 did not have hypervisor
mode enabled in its msr_mask, which meant we didn't actually run hypervisor
privilege checks in TCG at all. However, da874d90 "target/ppc: add HV
support for POWER9" turned on HV support on POWER9 for the benefit of the
powernv machine type.
This exposed the earlier bug in H_REGISTER_PROCESS_TABLE, and causes guests
which rely on LPCR[GTSE] (i.e. basically all of them) to crash during early
boot when their first tlbie instruction causes an unexpected trap.

qga-win: fix VSS build breakage due to unintended gnu99 C++ flag
Commit 7be41675f7c set -std=gnu99 for C code via QEMU_CFLAGS. Currently
we generate a "custom" QEMU_CXXFLAGS for VSS DLL C++ build by
filtering out some options from QEMU_CFLAGS and adding some others.
Since we don't filter out -std=gnu99 currently this breaks builds when
VSS support is enabled.
We could keep the existing approach, filter out -std=gnu99 from
QEMU_CFLAGS, and add -std=gnu++98, like configure currently does for
QEMU_CXXFLAGS, but as it turns out our resulting QEMU_CXXFLAGS would
be exactly what configure already generates, just with these filtered
out:
-fstack-protector-all -fstack-protector-strong
and these added:
-Wno-unknown-pragmas -Wno-delete-non-virtual-dtor

just handling these specific changes.

qga-win: include glib when building VSS DLL
Commit 3ebee3b191e defined assert() as g_assert(), but when we build
the VSS DLL component of QGA (to handle fsfreeze) we do not include
glib, which results in breakage when building with VSS support enabled.
Fix this by including glib (along with the -lintl and -lws2_32
dependencies it brings).
Since the VSS DLL is built statically, this introduces an additional
dependency on static glib and supporting libs for the mingw environment
(possibly why we didn't include glib originally), but VSS support
already has very specific prerequisites so it shouldn't affect too many
build environments.
Since the VSS DLL code does use qemu/osdep.h, this should also help
avoid future breakages and possibly allow for some clean ups in current
VSS code.

qga-win: Adding support for Windows Server 2019 get-osinfo command
Since Windows Server 2016, Microsoft stopped upgrading the major and minor
versions of their new Windows Server product, so, the current functionality
of checking major and minor version numbers to determine the Windows Server
version wont work as expected.
The implemented solution here is to use the build number in addition to the
major and minor version numbers of the product to determine the Windows
Server product version.
The final build number of Windows Server 2016 is 14939, and
the final build number of Windows Server 2019 is 17764, so any Windows
Server product that has the major version of 10 and minor version of 0
with a build number lower or equal to 14939 will resemble 2016 and if the
build number is lower or equal to 17763 will resemble 2019.

hw/pvrdma: Fix zero-initialization of resp in {query/modify}_qp
Make sure to zero-initialize only the pvrdma_cmd_query_qp_resp and not
the whole pvrdma_cmd_resp for query_qp, in modify_qp the resp isn't used
so remove it.
