Currently, when using a true R/O NVDIMM (ROM memory backend) with a label
area, the VM can easily crash QEMU by trying to write to the label area,
because the ROM memory is mmap'ed without PROT_WRITE.
[root@vm-0 ~]# ndctl disable-region region0
disabled 1 region
[root@vm-0 ~]# ndctl zero-labels nmem0
-> QEMU segfaults
Let's remember whether we have a ROM memory backend and properly
reject the write request:
[root@vm-0 ~]# ndctl disable-region region0
disabled 1 region
[root@vm-0 ~]# ndctl zero-labels nmem0
zeroed 0 nmem
In comparison, on a system with a R/W NVDIMM:
[root@vm-0 ~]# ndctl disable-region region0
disabled 1 region
[root@vm-0 ~]# ndctl zero-labels nmem0
zeroed 1 nmem
For ACPI, just return "unsupported", like if no label exists. For spapr,
return "H_P2", similar to when no label area exists.
Could we rely on the "unarmed" property? Maybe, but it looks cleaner to
only disallow what certainly cannot work.
After all "unarmed=on" primarily means: cannot accept persistent writes. In
theory, there might be setups where devices with "unarmed=on" set could
be used to host non-persistent data (temporary files, system RAM, ...); for
example, in Linux, admins can overwrite the "readonly" setting and still
write to the device -- which will work as long as we're not using ROM.
Allowing writing label data in such configurations can make sense.

x86_cpu_get_supported_cpuid() is generic and handles the different
accelerators. Use it instead of kvm_arch_get_supported_cpuid().
That fixes a link failure introduced by commit 3adce820cf
("target/i386: Remove unused KVM stubs") when QEMU is configured
as:
$ ./configure --cc=clang \
--target-list=x86_64-linux-user,x86_64-softmmu \
--enable-debug
We were getting:
[71/71] Linking target qemu-x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
For the record, this is because '--enable-debug' disables
optimizations (CFLAGS=-O0).
While at this (un)optimization level GCC eliminate the
following dead code (CPP output of mentioned build):
static void x86_cpu_get_supported_cpuid(uint32_t func, uint32_t index,
uint32_t *eax, uint32_t *ebx,
uint32_t *ecx, uint32_t *edx)
{
if ((0)) {
*eax = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EAX);
*ebx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EBX);
*ecx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_ECX);
*edx = kvm_arch_get_supported_cpuid(kvm_state, func, index, R_EDX);
} else if (0) {

*ebx = 0;
*ecx = 0;
*edx = 0;
} else {
*eax = 0;
*ebx = 0;

}
Clang does not (see commit 2140cfa51d "i386: Fix build by
providing stub kvm_arch_get_supported_cpuid()").

x86_cpu_get_supported_cpuid() already checks for KVM/HVF
accelerators, so it is not needed to manually check it via
a call to accel_uses_host_cpuid() before calling it.

qemu 8.1.0 breaks on illumos platforms due to _XOPEN_SOURCE and others no longer being set correctly, leading to breakage such as:
https://us-central.manta.mnx.io/pkgsrc/public/reports/trunk/tools/20230908.1404/qemu-8.1.0/build.log
This is a result of meson conversion which incorrectly matches against 'solaris' instead of 'sunos' for uname.
First time submitting a patch here, hope I did it correctly. Thanks.

Instead of using a variable-length array in nvme_map_prp(),
allocate on the stack with a g_autofree pointer.
The codebase has very few VLAs, and if we can get rid of them all we
can make the compiler error on new additions. This is a defensive
measure against security bugs where an on-stack dynamic allocation
isn't correctly size-checked (e.g. CVE-2021-3527).

In nvme_map_sgl() we create an array segment[] whose size is the
'const int SEG_CHUNK_SIZE'. Since this is C, rather than C++, a
"const int foo" is not a true constant, it's merely a variable with a
constant value, and so semantically segment[] is a variable-length
array. Switch SEG_CHUNK_SIZE to a #define so that we can make the
segment[] array truly fixed-size, in the sense that it doesn't
trigger the -Wvla warning.

can make the compiler error on new additions. This is a defensive

Enabling AP-passthrough(AP-pt) for PV-guest by using the new CPU
features for PV-AP-pt of KVM.
As usual QEMU first checks which CPU features are available and then
sets them if available and selected by user. An additional check is done
to verify that PV-AP can only be enabled if "regular" AP-pt is enabled
as well. Note that KVM itself does not enforce this restriction.

kvm_s390_set_attr() is a misleading name as it only sets attributes for
the KVM_S390_VM_CRYPTO group. Therefore, rename it to
kvm_s390_set_crypto_attr().
Add new functions ap_available() and ap_enabled() to avoid code
duplication later.

Bound APQNs have to be reset before tearing down the secure config via
s390_machine_unprotect(). Otherwise the Ultravisor will return a error
code.
So let's do a subsystem_reset() which includes a AP reset before the
unprotect call. We'll do a full device_reset() afterwards which will
reset some devices twice. That's ok since we can't move the
device_reset() before the unprotect as it includes a CPU clear reset
which the Ultravisor does not expect at that point in time.
