When network transport abstraction layer initialises pkt, the maximum
fragmentation count is not checked. This could lead to an integer
overflow causing a NULL pointer dereference. Replace g_malloc() with
g_new() to catch the multiplication overflow.

Considering that features are converted to global properties and
global properties are automatically applied to every new instance
of created CPU (at object_new() time), there is no point in
parsing cpu_model string every time a CPU created. So move
parsing outside CPU creation loop and do it only once.
Parsing also should be done before any CPU is created so that
features would affect the first CPU a well.
This patch does that for all PowerPC machine types.
It is based on previous work from Bharata:

The virtio-console.c file handles both serial consoles
and interactive consoles, since they're backed by the
same device model.
Since serial devices are expected to be reliable and
need to notify the guest when the backend is opened
or closed, the virtio-console.c file wires up support
for chardev events. This affects both serial consoles
and interactive consoles, using a network connection
based chardev backend such as 'socket', but not when
using a PTY based backend or plain 'file' backends.
When the host side is not connected the handle_output()
method in virtio-serial-bus.c will drop any data sent
by the guest, before it even reaches the virtio-console.c
code. This means that if the chardev has a logfile
configured, the data will never get logged.
Consider for example, configuring a x86_64 guest with a
plain UART serial port
-chardev socket,id=charserial1,host=127.0.0.1,port=9001,server,nowait,logfile=console1.log,logappend=on
-device isa-serial,chardev=charserial1,id=serial1
vs a s390 guest which has to use the virtio-console port
-chardev socket,id=charconsole1,host=127.0.0.1,port=9000,server,nowait,logfile=console2.log,logappend=on
-device virtconsole,chardev=charconsole1,id=console1
The isa-serial one gets data written to the log regardless
of whether a client is connected, while the virtioconsole
one only gets data written to the log when a client is
connected.
There is no need for virtio-serial-bus.c to aggressively
drop the data for console devices, as the chardev code is
prefectly capable of discarding the data itself.
So this patch changes virtconsole devices so that they
are always marked as having the host side open. This
ensures that the guest OS will always send any data it
has (Linux virtio-console hvc driver actually ignores
the host open state and sends data regardless, but we
should not rely on that), and also prevents the
virtio-serial-bus code prematurely discarding data.
The behaviour of virtserialport devices is *not* changed,
only virtconsole, because for the former, it is important
that the guest OSknow exactly when the host side is opened
/ closed so it can do any protocol re-negotiation that may
be required.

vhost-user: Attempt to fix a race with set_mem_table.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

The set_mem_table command currently does not seek a reply. Hence, there is
no easy way for a remote application to notify to QEMU when it finished
setting up memory, or if there were errors doing so.
As an example:
(1) Qemu sends a SET_MEM_TABLE to the backend (eg, a vhost-user net
application). SET_MEM_TABLE does not require a reply according to the spec.
(2) Qemu commits the memory to the guest.
(3) Guest issues an I/O operation over a new memory region which was configured on (1).
(4) The application has not yet remapped the memory, but it sees the I/O request.
(5) The application cannot satisfy the request because it does not know about those GPAs.
While a guaranteed fix would require a protocol extension (committed separately),
a best-effort workaround for existing applications is to send a GET_FEATURES
message before completing the vhost_user_set_mem_table() call.
Since GET_FEATURES requires a reply, an application that processes vhost-user
messages synchronously would probably have completed the SET_MEM_TABLE before replying.

This introduces the VHOST_USER_PROTOCOL_F_REPLY_ACK.
If negotiated, client applications should send a u64 payload in
response to any message that contains the "need_reply" bit set
on the message flags. Setting the payload to "zero" indicates the
command finished successfully. Likewise, setting it to "non-zero"
indicates an error.
Currently implemented only for SET_MEM_TABLE.

Hard-coding the CPU alias names in the spapr_cores[] array has
two big disadvantages:
1) We register a real type with the CPU alias name in
spapr_cpu_core_register_types() - this prevents us from registering
a CPU family name in kvm_ppc_register_host_cpu_type() with the same
name (as we do it for the non-hotpluggable CPU types).
2) It's quite cumbersome to maintain the aliases here in sync with the
ppc_cpu_aliases list from target-ppc/cpu-models.c.
So let's simply add proper alias lookup to the spapr cpu core code,
too (by checking whether the given model can be used directly, and
if not by trying to look up the given model as an alias name instead).

When a TCE table (sPAPR IOMMU context) is in disabled state (which is true
by default for the 64-bit window), it has tcet->nb_table == 0 and
tcet->table == NULL. However, on system reset, spapr_tce_reset() executes,
which unconditionally calls
memset(tcet->table, 0, table_size);
We get away with this in practice, because it's a zero length memset(),
but memset() on a NULL pointer is undefined behaviour, so we should not
call it in this case.

Prior to c8721d3 "spapr: Error out when CPU hotplug is attempted on older
pseries machines", attempting to use query-hotpluggable-cpus on pseries-2.6
and earlier machine types would SEGV.
That change fixed that, but due to some unexpected interactions in init
order and a brown-paper-bag worthy failure to test, it accidentally
disabled query-hotpluggable-cpus for all pseries machine types, including
the current one which should allow it.
In fact, query_hotpluggable_cpus needs to be non-NULL when and only when
the dr_cpu_enabled flag in sPAPRMachineClass is set, which makes
dr_cpu_enabled itself redundant.
This patch removes dr_cpu_enabled, instead directly setting
query_hotpluggable_cpus from the machine class_init functions, and using
that to determine the availability of CPU hotplug when necessary.

Follow John Snow recommendation:
Everywhere else ncq_err is used, it is accompanied by a list cleanup
except for ncq_cb, which is the case you are fixing here.
Move the sglist destruction inside of ncq_err and then delete it from
the other two locations to keep it tidy.
Call dma_buf_commit in ide_dma_cb after the early return. Though, this
is also a little wonky because this routine does more than clear the
list, but it is at the moment the centralized "we're done with the
sglist" function and none of the other side effects that occur in
dma_buf_commit will interfere with the reset that occurs from
ide_restart_bh, I think

The broken Identify implementation in earlier Qemu versions means we
need to blacklist it from issueing the NVMe 1.1 Identify Namespace List
command. As we want to be able to use it in newer Qemu versions we need
a way to identify those. Bump the PCI revision as a guest visible
indicator of this bug fix.

NVMe 1.1 requires devices to implement a Namespace List subcommand of
the identify command. Qemu not only not implements this features, but
also misinterprets it as an Identify Controller request. Due to this
any OS trying to use the Namespace List will fail the probe.

Some old Linux kernels (upstream before v4.0), or any released RHEL
kernels has problem in sending APIC EOI when IR is enabled. Meanwhile,
many of them only support explicit EOI for IOAPIC, which is only
introduced in IOAPIC version 0x20. This patch provide a way to boost
QEMU IOAPIC to version 0x20, in order for QEMU to correctly receive EOI
messages.
Without boosting IOAPIC version to 0x20, kernels before commit d32932d
("x86/irq: Convert IOAPIC to use hierarchical irqdomain interfaces")
will have trouble enabling both IR and level-triggered interrupt devices
(like e1000).
To upgrade IOAPIC to version 0x20, we need to specify:
-global ioapic.version=0x20
To be compatible with old systems, 0x11 will still be the default IOAPIC
version. Here 0x11 and 0x20 are the only versions to be supported.
One thing to mention: this patch only applies to emulated IOAPIC. It
does not affect kernel IOAPIC behavior.
