33badfd1e3 io: use case insensitive check for Connection & Upgrade websock headers
When checking the value of the Connection and Upgrade HTTP headers
the websock RFC (6455) requires the comparison to be case insensitive.
The Connection value should be an exact match not a substring.

3a3f870596 io: include full error message in websocket handshake trace
When the websocket handshake fails it is useful to log the real
error message via the trace points for debugging purposes.

f69a8bde29 io: send proper HTTP response for websocket errors
When any error occurs while processing the websockets handshake,
QEMU just terminates the connection abruptly. This is in violation
of the HTTP specs and does not help the client understand what they
did wrong. This is particularly bad when the client gives the wrong
path, as a "404 Not Found" would be very helpful.

Refactor the handshake code so that it always sends a response to
the client unless there was an I/O error.

11748ba72e kvm: check KVM_CAP_NR_VCPUS with kvm_vm_check_extension()
On a modern server-class ppc host with the following CPU topology:

Architecture:          ppc64le
Byte Order:            Little Endian
CPU(s):                32
On-line CPU(s) list:   0,8,16,24
Off-line CPU(s) list:  1-7,9-15,17-23,25-31
Thread(s) per core:    1

If both KVM PR and KVM HV loaded and we pass:

        -machine pseries,accel=kvm,kvm-type=PR -smp 8

We expect QEMU to warn that this exceeds the number of online CPUs:

Warning: Number of SMP cpus requested (8) exceeds the recommended
 cpus supported by KVM (4)
Warning: Number of hotpluggable cpus requested (8) exceeds the
 recommended cpus supported by KVM (4)

but nothing is printed...

This happens because on ppc the KVM_CAP_NR_VCPUS capability is VM
specific  ndreally depends on the KVM type, but we currently use it
as a global capability. And KVM returns a fallback value based on
KVM HV being present. Maybe KVM on POWER shouldn't presume anything
as long as it doesn't have a VM, but in all cases, we should call
KVM_CREATE_VM first and use KVM_CAP_NR_VCPUS as a VM capability.

This patch hence changes kvm_recommended_vcpus() accordingly and
moves the sanity checking of smp_cpus after the VM creation.

It is okay for the other archs that also implement KVM_CAP_NR_VCPUS,
ie, mips, s390, x86 and arm, because they don't depend on the VM
being created or not.

62dd4edaaf kvm: check KVM_CAP_SYNC_MMU with kvm_vm_check_extension()
On a server-class ppc host, this capability depends on the KVM type,
ie, HV or PR. If both KVM are present in the kernel, we will always
get the HV specific value, even if we explicitely requested PR on
the command line.

This can have an impact if we're using hugepages or a balloon device.

Since we've already created the VM at the time any user calls
kvm_has_sync_mmu(), switching to kvm_vm_check_extension() is
enough to fix any potential issue.

It is okay for the other archs that also implement KVM_CAP_SYNC_MMU,
ie, mips, s390, x86 and arm, because they don't depend on the VM being
created or not.

While here, let's cache the state of this extension in a bool variable,
since it has several users in the code, as suggested by Thomas Huth.

f0df84c6c4 watchdog: Allow setting action on the fly
Currently, the only time that users can set watchdog action is at
the start as all we expose is this -watchdog-action command line
argument. This is suboptimal when users want to plug the device
later via monitor. Alternatively, they might want to change the
action for already existing device on the fly.

299d296ea9 docker: Fix test-mingw
Feature "dtc" is explicitly required by test-mingw, but is not detected
by the run script since we switched to archive-source.sh in b7f404201e.
Since it isn't available in the Fedora image which runs this test on
patchew, the way we get dtc is still from submodule.

archive-source.sh takes care of bundling the submodule files already, so
what we need to do is just checking if files are there. Makefile is
chosen because it is one that is unlikely to get renamed in the future.

44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

9ac78b6171 migration: disable auto-converge during bulk block migration
auto-converge and block migration currently do not play well together.
During block migration the auto-converge logic detects that ram
migration makes no progress and thus throttles down the vm until
it nearly stalls completely. Avoid this by disabling the throttling
logic during the bulk phase of the block migration.

These fields were used to manually handle IO requests that weren't aligned
to a sector boundary before this feature was supported by the block API.

Once the block API changed to support byte-aligned IO requests, the macio
controller was switched over to use it in commit be1e343 but these fields
were accidentally left behind. Remove them, including the initialisation
in DBDMA_init().

1ec26c757d spapr: fix the value of SDR1 in kvmppc_put_books_sregs()
When running with KVM PR, if a new HPT is allocated we need to inform
KVM about the HPT address and size. This is currently done by hacking
the value of SDR1 and pushing it to KVM in several places.

Also, migration breaks the guest since it is very unlikely the HPT has
the same address in source and destination, but we push the incoming
value of SDR1 to KVM anyway.

This patch introduces a new virtual hypervisor hook so that the spapr
code can provide the correct value of SDR1 to be pushed to KVM each
time kvmppc_put_books_sregs() is called.

It allows to get rid of all the hacking in the spapr/kvmppc code and
it fixes migration of nested KVM PR.

30b3bc5aa9 spapr_pci: make index property mandatory
PHBs can be created with an index property, in which case the machine
code automatically sets all the MMIO windows at addresses derived from
the index. Alternatively, they can be manually created without index,
but the user has to provide addresses for all MMIO windows.

The non-index way happens to be more trouble than it's worth: it's
difficult to use, keeps requiring (potentially incompatible) changes
when some new parameter needs adding, and is awkward to check for
collisions. It currently even has a bug that prevents to use two
non-index PHBs because their child DRCs are all derived from the
same index == -1 value, and, thus, collide.

This patch hence makes the index property mandatory. As a consequence,
the PHB's memory regions and BUID are now always configured according
to the index, and it is no longer possible to set them from the command
line.

This DOES BREAK backwards compat, but we don't think the non-index
PHB feature was used in practice (at least libvirt doesn't) and the
simplification is worth it.

5261158d21 ppc/pnv: Improve macro parenthesization
Although none of the existing macro call-sites were broken,
it's always better to write macros that properly parenthesize
arguments that can be complex expressions, so that the intended
order of operations is not broken.
