Paolo Bonzini 7e46261368 virtfs-proxy-helper: switch from libcap to libcap-ng
virtfs-proxy-helper is the only user of libcap; everyone else is using
the simpler libcap-ng API.  Switch and remove the configure code to
detect libcap.

Claudio Imbrenda f24ec9fead pc-bios/s390-ccw: fix sclp_get_loadparm_ascii
The existing s390 bios gets the LOADPARM information from the system using
an SCLP call that specifies a buffer length too small to contain all the
output.

The recent fixes in the SCLP code have exposed this bug, since now the
SCLP call will return an error (as per architecture) instead of
writing partially and completing successfully.

The solution is simply to specify the full page length as the SCCB
length instead of a smaller size.

Fixes: 832be0d8a3 ("s390x: sclp: Report insufficient SCCB length")
Fixes: 9a22473c70 ("pc-bios/s390-ccw: get LOADPARM stored in SCP Read Info")

   * Changes to make VFIO devices interact properly with change of irq
     chip caused by PAPR feature negotiation.  This is more involved
     than I would like, but it's a problem in real use cases and I
     can't see an easier way to handle it.
   * Fix an error with ms6522 counters for the g3beige machine

Marc Zyngier 6a4ef4e5d1 target/arm: Honor HCR_EL2.TID3 trapping requirements
HCR_EL2.TID3 mandates that access from EL1 to a long list of id
registers traps to EL2, and QEMU has so far ignored this requirement.

This breaks (among other things) KVM guests that have PtrAuth enabled,
while the hypervisor doesn't want to expose the feature to its guest.
To achieve this, KVM traps the ID registers (ID_AA64ISAR1_EL1 in this
case), and masks out the unsupported feature.

QEMU not honoring the trap request means that the guest observes
that the feature is present in the HW, starts using it, and dies
a horrible death when KVM injects an UNDEF, because the feature
*really* isn't supported.

Do the right thing by trapping to EL2 if HCR_EL2.TID3 is set.

Note that this change does not include trapping of the MVFR
registers from AArch32 (they are accessed via the VMRS
instruction and need to be handled in a different way).

Marc Zyngier 7cf95aed53 target/arm: Fix ISR_EL1 tracking when executing at EL2
The ARMv8 ARM states when executing at EL2, EL3 or Secure EL1,
ISR_EL1 shows the pending status of the physical IRQ, FIQ, or
SError interrupts.

Unfortunately, QEMU's implementation only considers the HCR_EL2
bits, and ignores the current exception level. This means a hypervisor
trying to look at its own interrupt state actually sees the guest
state, which is unexpected and breaks KVM as of Linux 5.3.

Instead, check for the running EL and return the physical bits
if not running in a virtualized context.

David Gibson b14848f5d7 spapr: Work around spurious warnings from vfio INTx initialization
Traditional PCI INTx for vfio devices can only perform well if using
an in-kernel irqchip.  Therefore, vfio_intx_update() issues a warning
if an in kernel irqchip is not available.

We usually do have an in-kernel irqchip available for pseries machines
on POWER hosts.  However, because the platform allows feature
negotiation of what interrupt controller model to use, we don't
currently initialize it until machine reset.  vfio_intx_update() is
called (first) from vfio_realize() before that, so it can issue a
spurious warning, even if we will have an in kernel irqchip by the
time we need it.

To workaround this, make a call to spapr_irq_update_active_intc() from
spapr_irq_init() which is called at machine realize time, before the
vfio realize.  This call will be pretty much obsoleted by the later
call at reset time, but it serves to suppress the spurious warning
from VFIO.

David Gibson e532e1d93c spapr: Handle irq backend changes with VFIO PCI devices
pseries machine type can have one of two different interrupt controllers in
use depending on feature negotiation with the guest.  Usually this is
invisible to devices, because they route to a common set of qemu_irqs which
in turn dispatch to the correct back end.

VFIO passthrough devices, however, wire themselves up directly to the KVM
irqchip for performance, which means they are affected by this change in
interrupt controller.  To get them to adjust correctly for the change in
irqchip, we need to fire the kvm irqchip change notifier.

David Gibson c5478fea27 vfio/pci: Respond to KVM irqchip change notifier
VFIO PCI devices already respond to the pci intx routing notifier, in order
to update kernel irqchip mappings when routing is updated.  However this
won't handle the case where the irqchip itself is replaced by a different
model while retaining the same routing.  This case can happen on
the pseries machine type due to PAPR feature negotiation.

To handle that case, add a handler for the irqchip change notifier, which
does much the same thing as the routing notifier, but is unconditional,
rather than being a no-op when the routing hasn't changed.

David Gibson 3607715a30 kvm: Introduce KVM irqchip change notifier
Awareness of an in kernel irqchip is usually local to the machine and its
top-level interrupt controller.  However, in a few cases other things need
to know about it.  In particular vfio devices need this in order to
accelerate interrupt delivery.

If interrupt routing is changed, such devices may need to readjust their
connection to the KVM irqchip.  pci_bus_fire_intx_routing_notifier() exists
to do just this.

However, for the pseries machine type we have a situation where the routing
remains constant but the top-level irq chip itself is changed.  This occurs
because of PAPR feature negotiation which allows the guest to decide
between the older XICS and newer XIVE irq chip models (both of which are
paravirtualized).

To allow devices like vfio to adjust to this change, introduce a new
notifier for the purpose kvm_irqchip_change_notify().

Zhuang, Siwei (Data61, Kensington NSW) 6478dd745d hw/riscv: Add optional symbol callback ptr to riscv_load_kernel()
This patch adds an optional function pointer, "sym_cb", to
riscv_load_kernel() which provides the possibility to access the symbol
table during kernel loading.

The pointer is ignored, if supplied with Image or uImage file.

The Spike board requires the access to locate the HTIF symbols.

Palmer Dabbelt 9c0fb20c4b RISC-V: virt: This is a "sifive,test1" test finisher
The test finisher implements the reset command, which means it's a
"sifive,test1" device.  This is a backwards compatible change, so it's
also a "sifive,test0" device.  I copied the odd idiom for adding a
two-string compatible field from the ARM virt board.

Jens Freimann 150ab54aa6 net/virtio: fix re-plugging of primary device
failover_replug_primary was returning true on failure which lead to
re-plug not working when a migration failed.  Fix this by returning
success when hotplug worked.  This is a bug that was missed in last
round of testing but was tested succesfully with this version.  Also
make sure we don't pass NULL to qdev_set_parent_bus().

This fixes CID 1407224.

Jens Freimann 284f42a520 net/virtio: fix dev_unplug_pending
.dev_unplug_pending is set up by virtio-net code indepent of failover
support was set for the device or not. This gives a wrong result when
we check for existing primary devices in migration code.

Fix this by actually calling dev_unplug_pending() instead of just
checking if the function pointer was set. When the feature was not
negotiated dev_unplug_pending() will always return false. This prevents
us from going into the wait-unplug state when there's no primary device
present.
