26f603d4f8 travis.yml: Drop libcap-dev
Commit 7e46261368 converted virtfs-proxy-helper to using libcap-ng. There
aren't any users of libcap anymore. No need to install libcap-dev.

24e15a0b69 ci: Use libcap-ng
We currently enable libcap-dev in build-clang to pick up the 9p proxy
helper.  Paolo's patch changes (commit 7e46261368) that to use
libcap-ng, so switch to using it.  This also means we'll be testing the
scsi pr manager and the bridge helper.

  block/qcow2-bitmap: fix crash bug in qcow2_co_remove_persistent_dirty_bitmap

f56281abd9 block/qcow2-bitmap: fix crash bug in qcow2_co_remove_persistent_dirty_bitmap
Here is double bug:

First, return error but not set errp. This may lead to:
qmp block-dirty-bitmap-remove may report success when actually failed

block-dirty-bitmap-remove used in a transaction will crash, as
qmp_transaction will think that it returned success and will call
block_dirty_bitmap_remove_commit which will crash, as state->bitmap is
NULL

Second (like in anecdote), this case is not an error at all. As it is
documented in the comment above bdrv_co_remove_persistent_dirty_bitmap
definition, absence of bitmap is not an error, and similar case handled
at start of qcow2_co_remove_persistent_dirty_bitmap, it returns 0 when
there is no bitmaps at all.

But when there are some bitmaps, but not the requested one, it return
error with errp unset.

Fix that.

Trigger:
1. create persistent bitmap A
2. shutdown vm  (bitmap A is synced)
3. start vm
4. create persistent bitmap B
5. remove bitmap B - it fails (and crashes if in transaction)

Potential workaround (rather invasive to ask clients to implement it):
1. create persistent bitmap A
2. shutdown vm
3. start vm
4. create persistent bitmap B
5. remember, that we want to remove bitmap B after vm shutdown
...
  some other operations
...
6. vm shutdown
7. start vm in stopped mode, and remove all bitmaps marked for removing
8. stop vm

This is a last minute pull request for ppc-for-4.2.  I know it's very
 late in freeze, but this does fix a regression: a bad interaction
 between the new qemu and SLOF device tree construction code means that
 SLOF will crash if PCI to PCI bridges are included in the system.
 
 This PR supersedes ppc-for-4.2-20191206.  This one has only a more
 minimal change to the firmware addressed only at fixing this bug and
 not incorporating some other unrelated changes that happened in the
 meantime.

cb09104ea8 block/file-posix: Fix laio_init() error handling crash bug
raw_aio_attach_aio_context() passes uninitialized Error *local_err by
reference to laio_init() via aio_setup_linux_aio().  When laio_init()
fails, it passes it on to error_setg_errno(), tripping error_setv()'s
assertion unless @local_err is null by dumb luck.

Fix by initializing @local_err properly.

5a0948d36c net/virtio: Fix failover error handling crash bugs
Functions that take an Error ** parameter to pass an error to the
caller expect the parameter to point to null.
failover_replug_primary() violates this precondition in several
places:

* After qemu_opts_from_qdict() failed, *errp is no longer null.
  Passing it to error_setg() is wrong, and will trip the assertion in
  error_setv().  Messed up in commit 150ab54aa6 "net/virtio: fix
  re-plugging of primary device".  Simply drop the error_setg().

* Passing @errp to qemu_opt_set_bool(), hotplug_handler_pre_plug(),
  and hotplug_handler_plug() is wrong.  If one of the first two fails,
  *errp is no longer null.  Risks tripping the same assertion.
  Moreover, continuing after such errors is unsafe.  Messed up in
  commit 9711cd0dfc "net/virtio: add failover support".  Fix by
  handling each error properly.

failover_replug_primary() crashes when passed a null @errp.  Also
messed up in commit 9711cd0dfc.  This bug can't bite as no caller
actually passes null.  Fix it anyway.

4dbac1aed2 net/virtio: Drop useless n->primary_dev not null checks
virtio_net_handle_migration_primary() returns early when it can't
ensure n->primary_dev is non-null.  Checking it again right after that
early return is redundant.  Drop.

If n->primary_dev is null on entering failover_replug_primary(), @pdev
will become null, and pdev->partially_hotplugged will crash.  Checking
n->primary_dev later is useless.  It can't actually be null, because
its caller virtio_net_handle_migration_primary() ensures it isn't.
Drop the useless check.

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")

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).

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.

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.

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.

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.

ad54dbd89d vfio/pci: Split vfio_intx_update()
This splits the vfio_intx_update() function into one part doing the actual
reconnection with the KVM irqchip (vfio_intx_update(), now taking an
argument with the new routing) and vfio_intx_routing_notifier() which
handles calls to the pci device intx routing notifier and calling
vfio_intx_update() when necessary.  This will make adding support for the
irqchip change notifier easier.
