test-logging: don't hard-code paths in /tmp
Since
f6880b7f [qemu-log: support simple pid substitution for logs],
test-logging creates files with hard-coded names in /tmp. In the best
case, this prevents multiple developers from running "make check" on
the same machine. In the worst case, it allows for symlink attacks,
enabling an attacker to overwrite files that are writable to the
developer running "make check".
Instead of hard-coding the paths, create a temporary directory using
g_dir_make_tmp() and clean it up afterwards.

block: fix possible reorder of flush operations
This patch reduce CPU usage of flush operations a bit. When we have one
flush completed we should kick only next operation. We should not start
all pending operations in the hope that they will go back to wait on
wait_queue.
Also there is a technical possibility that requests will get reordered
with the previous approach. After wakeup all requests are removed from
the wait queue. They become active and they are processed one-by-one
adding to the wait queue in the same order. Though new flush can arrive
while all requests are not put into the queue.

block: ignore flush requests when storage is clean
has introduced a regression.
There is a problem that it is still possible for 2 requests to execute
in non sequential fashion and sometimes this results in a deadlock
when bdrv_drain_one/all are called for BDS with such stalled requests.
1. Current flushed_gen and flush_started_gen is 1.
2. Request 1 enters bdrv_co_flush to with write_gen 1 (i.e. the same
as flushed_gen). It gets past flushed_gen != flush_started_gen and
sets flush_started_gen to 1 (again, the same it was before).
3. Request 1 yields somewhere before exiting bdrv_co_flush
4. Request 2 enters bdrv_co_flush with write_gen 2. It gets past
flushed_gen != flush_started_gen and sets flush_started_gen to 2.
5. Request 2 runs to completion and sets flushed_gen to 2
6. Request 1 is resumed, runs to completion and sets flushed_gen to 1.
However flush_started_gen is now 2.
From here on out flushed_gen is always != to flush_started_gen and all
further requests will wait on flush_queue. This change replaces
flush_started_gen with an explicitly tracked active flush request.

linux-user: Fix llseek with high bit of offset_low set
The llseek syscall takes two 32-bit arguments, offset_high
and offset_low, which must be combined to form a single
64-bit offset. Unfortunately we were combining them with
(uint64_t)arg2 << 32) | arg3
and arg3 is a signed type; this meant that when promoting
arg3 to a 64-bit type it would be sign-extended. The effect
was that if the offset happened to have bit 31 set then
this bit would get sign-extended into all of bits 63..32.

Since commit

so vhost-user could wait until a backend started successfully. In
vhost-user case, the chr socket must be plain unix, and the chr+vhost
setup happens synchronously during qemu startup.
However, with TLS and telnet socket, initial socket setup happens
asynchronously, and s->connected is not set after the socket is
accepted. In order for tcp_chr_wait_connected() to not keep accepting

check for s->ioc instead.

pc-bios/optionrom: Fix OpenBSD build with better detection of linker emulation
The various host OSes are irritatingly variable about the name
of the linker emulation we need to pass to ld's -m option to
build the i386 option ROMs. Instead of doing this via a
CONFIG ifdef, check in configure whether any of the emulation
names we know about will work and pass the right answer through
to the makefile. If we can't find one, we fall back to not trying
to build the option ROMs, in the same way we would for a non-x86
host platform.
This is in particular necessary to unbreak the build on OpenBSD,
since it wants a different answer to FreeBSD and we don't have
an existing CONFIG_ variable that distinguishes the two.

xen: handle inbound migration of VMs without ioreq server pages
VMs created on older versions on Xen will not have been provisioned with
pages to support creation of non-default ioreq servers. In this case
the ioreq server API is not supported and QEMU's only option is to fall
back to using the default ioreq server pages as it did prior to
commit
3996e85c ("Xen: Use the ioreq-server API when available").
This patch therefore changes the code in xen_common.h to stop considering
a failure of xc_hvm_create_ioreq_server() as a hard failure but simply
as an indication that the guest is too old to support the ioreq server
API. Instead a boolean is set to cause reversion to old behaviour such
that the default ioreq server is then used.

virtio-console: set frontend open permanently for console devs
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.

(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.

ppc/kvm: Register also a generic spapr CPU core family type
There is a regression with the "-cpu" parameter introduced by
the spapr CPU hotplug code: We used to allow to specify a
"CPU family" name with the "-cpu" parameter when running on KVM so
that the user does not need to know the gory details of the exact
CPU version of the host CPU. For example, it was possible to
use "-cpu POWER8" on a POWER8E host CPU. This behavior does not
work anymore with the new hot-pluggable spapr-cpu-core types.
Since libvirt already heavily depends on the old behavior, this
is quite a severe regression in the QEMU parameter interface.
Let's fix it by supporting a CPU family type for the spapr-cpu-core
on KVM, too.

two big disadvantages:
1) We register a real type with the CPU alias name in

a CPU family name in kvm_ppc_register_host_cpu_type() with the same

2) It's quite cumbersome to maintain the aliases here in sync with the
ppc_cpu_aliases list from target-ppc/cpu-models.c.

This dump cannot be read by crash:

Page_size is used to determine the dumpfile's block size. The

timer: set vm_clock disabled default
(commit
80dcfb8532ae76343109a48f12ba8ca1c505c179)
Upon migration, the code use a timer based on vm_clock for 1ns
in the future from post_load to do the event send in case host_connected
differs between migration source and target.
However, it's not guaranteed that the apic is ready to inject irqs into
the guest, and the irq line remained high, resulting in any future interrupts
going unnoticed by the guest as well.
That's because 1) the migration coroutine is not blocked when it get EAGAIN
while reading QEMUFile. 2) The vm_clock is enabled default currently, it doesn't
rely on the calling of vm_start(), that means vm_clock timers can run before
VCPUs are running.
So, let's set the vm_clock disabled default, keep the initial intention of
design for vm_clock timers.
Meanwhile, change the test-aio usecase, using QEMU_CLOCK_REALTIME instead of
QEMU_CLOCK_VIRTUAL as the block code does.

linuxboot_dma: avoid guest ABI breakage on gcc vs. clang compilation
Recent GCC compiles linuxboot_dma.c to 921 bytes, while CentOS 6 needs
1029 and clang needs 1527. Because the size of the ROM, rounded to the
next 512 bytes, must match, this causes the API to break between a <1K
ROM and one that is bigger.
We want to make the ROM 1.5 KB in size, but it's better to make clang
produce leaner ROMs, because currently it is worryingly close to the limit.
To fix this prevent clang's happy inlining (which -Os cannot prevent).
This only requires adding a noinline attribute.
Second, the patch makes sure that the ROM has enough padding to prevent
ABI breakage on different compilers. The size is now hardcoded in the file
that is passed to signrom.py, as was the case before commit
6f71b77
("scripts/signrom.py: Allow option ROM checksum script to write the size
header.", 2016-05-23); signrom.py however will still pad the input to
the requested size. This ensures that the padding goes beyond the
next multiple of 512 if necessary, and also avoids the need for
-fno-toplevel-reorder which clang doesn't support. signrom.py can then
error out if the requested size is too small for the actual size of the
compiled ROM.

audio: clean up before monitor clean up
Since
aa5cb7f5e, the chardevs are being cleaned up when leaving qemu,
before the atexit() handlers. audio_cleanup() may use the monitor to
notify of changes. For compatibility reasons, let's clean up audio
before the monitor so it keeps emitting monitor events.
The audio_atexit() function is made idempotent (so it can be called
multiple times), and renamed to audio_cleanup(). Since coreaudio
backend is using a 'isAtexit' code path, change it to check
audio_is_cleaning_up() instead, so the path is taken during normal
exit.

BLOCK_JOB_COMPLETED with zero progress.
After
