Copy snapshots out of QCOW2 disk
In order to backup snapshots, created from QCOW2 iamge, we want to copy snapshots out of QCOW2 disk to a seperate storage.
The following patch adds a new option in "qemu-img": qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img.
Right now, it only supports to copy the full snapshot, delta snapshot is on the way.
Changes from V1: all the comments from Kevin are addressed:
Add read-only checking
Fix coding style
Change the name from bdrv_snapshot_load to bdrv_snapshot_load_tmp

The message "Truncating memory to %d MiB to fit SDRAM controller limits"

can't be represented by the PPC 4xx SDRAM controller (e.g. 129MB, which
would only be valid if the controller supports a bank size of 1MB).

alpha-linux-user: Fix sigprocmask.
Alpha passes oldset by value in a register, and returns the newset
as the return value; as compared to the standard implementation in
which both are passed by reference. This requires being able to
distinguish negative return values that are not errors. Do this in
the same way as the Alpha Linux kernel, by storing a zero in V0 in
the implementation of the syscall.
At the same time, fix a think-o in the regular sigprocmask path in
which we passed the target, rather than the host, HOW value.

more alarm timer cleanup
The timer_alarm_pending variable is related to the alarm timer but not
placed in the struct. Also, in qemu_mod_timer the wrong flag was being
tested: the timer is rearmed in the alarm timer "bottom half", so the
right flag to test there is the "pending" flag.
Finally, I hoisted the NULL checks from alarm_has_dynticks to
host_alarm_handler.

QMP: Introduce commands documentation
One of the most important missing feature in QMP today is its
supported commands documentation.
The plan is to make it part of self-description support, however
self-description is a big task we have been postponing for a
long time now and still don't know when it's going to be done.
In order not to compromise QMP adoption and make users' life easier,
this commit adds a simple text documentation which fully describes
all QMP supported commands.
This is not ideal for a number of reasons (harder to maintain,
text-only, etc) but does improve the current situation. To avoid at
least divering from the user monitor help and texi snippets, QMP bits
are also maintained inside qemu-monitor.hx, and hxtool is extended to
generate a single text file from them.

target-sh4: MMU: optimize UTLB accesses
With the current code, the QEMU TLB is setup to match the read/write
mode of the MMU fault. This means when read access is done, the page
is setup in read-only mode. When the page is later accessed in write
mode, an MMU fault happened, and the page is switch in write-only
mode. This flip-flop causes a lot of calls to the MMU code and slow
down the emulation.
This patch changes the MMU emulation, so that the QEMU TLB is setup
to match the UTLB protection key. This impressively increase the
speed of the emulation.

virtio-serial-bus: Add a port 'name' property for port discovery in guests
The port 'id' or number is internal state between the guest kernel and
our bus implementation. This is invocation-dependent and isn't part of
the guest-host ABI.
To correcly enumerate and map ports between the host and the guest, the
'name' property is used.
Example:
-device virtserialport,name=org.qemu.port.0
This invocation will get us a char device in the guest at:
/dev/virtio-ports/org.qemu.port.0
which can be a symlink to
/dev/vport0p3
This 'name' property is exposed by the guest kernel in a sysfs
attribute:
/sys/kernel/virtio-ports/vport0p3/name
A simple udev script can pick up this name and create the symlink
mentioned above.

VNC: Cache client info at connection time
When a disconnection happens the client's socket on QEMU
side may become invalid, this way it won't be possible
to query it to get client information, which is going to
be needed by the future QMP VNC_DISCONNECTED event.
To always have this information available we query the
socket at connection time and cache the client info in
struct VncState.
Two function are introduced to perform this job.
vnc_client_cache_addr() is called right when the connection
is made, however the authentication information is not
available at that moment so vnc_client_cache_auth() is
called from protocol_client_init() to get auth info.

default devices: core code & serial lines.
Qemu creates a default serial line for you in case you didn't specify
one on the command line. Right now this is tied to the '-serial
<chardev>' command line switch, which in turn causes trouble if you are
creating your serial line via '-device isa-serial,<props>'.
This patch adds a variable default_serial which says whenever a default
serial line should be added. It is enabled by default. It is cleared
when qemu finds '-serial' or '-device isa-serial' on the command line.
Part of the patch is some infrastructure for the '-device $driver'
checking (default_driver_check function) which will also be used by the
other patches of this series.

target-i386: add lock mov cr0 = cr8
AMD CPUs featuring a shortcut to access CR8 even from 32-bit mode.
If you use the LOCK prefix with "mov CR0", it accesses CR8 instead.
This behavior is guarded by the CR8_LEGACY CPUID bit
(Fn8000_0001:ECX[1]).

Introduce QEMU_CLOCK_HOST
Despite its name QEMU_CLOCK_REALTIME is (normally) not using
CLOCK_REALTIME / the host system time as base. In order to allow also
non-trivial RTC emulations (MC146818) to follow the host time instead of
the virtual guest time, introduce the new clock type QEMU_CLOCK_HOST. It
is unconditionally based on CLOCK_REALTIME, thus will follow system time
changes of the host.
The only limitation of its current implementation is that pending
host_clock timers may not fire early if the host time is pushed forward
beyond their expiry. So far no urgent need to overcome this limitation
was identified, so it's left as simple as it is (expiry on next alarm
timer tick).

Ignore -Waddress for alsaaudio.c
/usr/include/alsa/pcm.h contains:
#define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0)
The assert generates: "error: the address of 'sw_params' will always
evaluate as 'true'" which combined with -Werror prevents alsaaudio.o
from being built with certain versions of GCC.

raw-posix: refactor AIO support
Currently the raw-posix.c code contains a lot of knowledge about the
asynchronous I/O scheme that is mostly implemented in posix-aio-compat.c.
All this code does not really belong here and is getting a bit in the
way of implementing native AIO on Linux.
So instead move all the guts of the AIO implementation into
posix-aio-compat.c (which might need a better name, btw).
There's now a very small interface between the AIO providers and raw-posix.c:
- an init routine is called from raw_open_common to return an AIO context
for this drive. An AIO implementation may either re-use one context
for all drives, or use a different one for each as the Linux native
AIO support will do.
- an submit routine is called from the aio_reav/writev methods to submit
an AIO request
There are no indirect calls involved in this interface as we need to
decide which one to call manually. We will only call the Linux AIO native
init function if we were requested to by vl.c, and we will only call
the native submit function if we are asked to and the request is properly
aligned. That's also the reason why the alignment check actually does
the inverse move and now goes into raw-posix.c.
The old posix-aio-compat.h headers is removed now that most of it's
content is private to posix-aio-compat.c, and instead we add a new
block/raw-posix-aio.h headers is created containing only the tiny interface
between raw-posix.c and the AIO implementation.

target-i386: SVM: acknowledge interrupt only after it is taken
SVM specifies that the V_IRQ mask is only to be removed, if the
interrupt that is to be delivered actually is delivered.
As of the SVM rewrite, this mask is always unmasked when the main cpu
loop is processed, leaving a corner case where calling the interrupt
handler causes a #PF. In that case (booting Linux / starting gfxboot)
the current implementation tells the VMM the interrupt is taken, even
though it is not.
This patch modifies the VIRQ unmasking to occur after do_interrupt,
making gfxboot work again.

Allow to register a callback with fw_cfg_add_callback()

after masking the key with FW_CFG_ENTRY_MASK.
But as FW_CFG_ENTRY_MASK is ~(FW_CFG_WRITE_CHANNEL | FW_CFG_ARCH_LOCAL),
the bit is never set and function exits.
This patch corrects this by checking the bit before masking the value.

Coverity warnings CID 1385146, 1385148 1385149 and 1385150 point that
xtensa_opcode_num_operands and xtensa_format_num_slots may return -1
even when xtensa_opcode_decode and xtensa_format_decode succeed. In that
case unsigned counters used to iterate through operands/slots will not
do the right thing.
Make counters and loop bounds signed to fix the warnings.

hw/intc/arm_gic: Prevent the GIC from signaling an IRQ when it's "active and pending"
In the GIC, when an IRQ is acknowledged, its state goes from "pending"
to:
- "active" if the corresponding IRQ pin has been de-asserted
- "active and pending" otherwise.
The GICv2 manual states that when a IRQ becomes active (or active and
pending), the GIC should either signal another (higher priority) IRQ to
the CPU if there is one, or de-assert the CPU IRQ pin.
The current implementation of the GIC in QEMU does not check if the
IRQ is already active when looking for pending interrupts with
sufficient priority in gic_update(). This can lead to signaling an
interrupt that is already active.
This usually happens when splitting priority drop and interrupt
deactivation. On priority drop, the IRQ stays active until deactivation.
If it becomes pending again, chances are that it will be incorrectly
selected as best_irq in gic_update().
This commit fixes this by checking if the IRQ is not already active when
looking for best_irq in gic_update().
Note that regarding the ARM11MPCore GIC version, the corresponding
manual is not clear on that point, but it has has no priority
drop/interrupt deactivation separation, so this case should not happen.

qapi: Implement boxed types for commands/events
Turn on the ability to pass command and event arguments in
a single boxed parameter, which must name a non-empty type
(although the type can be a struct with all optional members).
For structs, it makes it possible to pass a single qapi type
instead of a breakout of all struct members (useful if the
arguments are already in a struct or if the number of members
is large); for other complex types, it is now possible to use
a union or alternate as the data for a command or event.
The empty type may be technically feasible if needed down the
road, but it's easier to forbid it now and relax things to allow
it later, than it is to allow it now and have to special case
how the generated 'q_empty' type is handled (see commit 7ce106a9
for reasons why nothing is generated for the empty type). An
alternate type is never considered empty, but now that a boxed
type can be either an object or an alternate, we have to provide
a trivial QAPISchemaAlternateType.is_empty(). The new call to
arg_type.is_empty() during QAPISchemaCommand.check() requires
that we first check the type in question; but there is no chance
of introducing a cycle since objects do not refer back to commands.
We still have a split in syntax checking between ad-hoc parsing
up front (merely validates that 'boxed' has a sane value) and
during .check() methods (if 'boxed' is set, then 'data' must name
a non-empty user-defined type).
Generated code is unchanged, as long as no client uses the
new feature.

spapr: Treat Hardware Transactional Memory (HTM) as an optional capability
This adds an spapr capability bit for Hardware Transactional Memory. It is
enabled by default for pseries-2.11 and earlier machine types. with POWER8
or later CPUs (as it must be, since earlier qemu versions would implicitly
allow it). However it is disabled by default for the latest pseries-2.12
machine type.
This means that with the latest machine type, HTM will not be available,
regardless of CPU, unless it is explicitly enabled on the command line.
That change is made on the basis that:
* This way running with -M pseries,accel=tcg will start with whatever cpu
and will provide the same guest visible model as with accel=kvm.
- More specifically, this means existing make check tests don't have
to be modified to use cap-htm=off in order to run with TCG
* We hope to add a new "HTM without suspend" feature in the not too
distant future which could work on both POWER8 and POWER9 cpus, and
could be enabled by default.
* Best guesses suggest that future POWER cpus may well only support the
HTM-without-suspend model, not the (frankly, horribly overcomplicated)
POWER8 style HTM with suspend.
* Anecdotal evidence suggests problems with HTM being enabled when it
wasn't wanted are more common than being missing when it was.

vnc: make sure we finish disconnect
Added a check for vs->disconnecting at the very start of the
vnc_update_client method. This means that the very next "if"
statement check for !vs->disconnecting always evaluates true,
and is thus redundant. This in turn means the vs->disconnecting
check at the very end of the method never evaluates true, and
is thus unreachable code.

qemu-img: Add find_nonzero()
During 'qemu-img compare', when we are checking that an allocated
portion of one file is all zeros, we don't need to waste time
computing how many additional sectors after the first non-zero
byte are also non-zero. Create a new helper find_nonzero() to do
the check for a first non-zero sector, and rebase
check_empty_sectors() to use it.
The new interface intentionally uses bytes in its interface, even
though it still crawls the buffer a sector at a time; it is robust
to a partial sector at the end of the buffer.

block: Allow NULL file for bdrv_get_block_status()
Not all callers care about which BDS owns the mapping for a given
range of the file. This patch merely simplifies the callers by
consolidating the logic in the common call point, while guaranteeing
a non-NULL file to all the driver callbacks, for no semantic change.
The only caller that does not care about pnum is bdrv_is_allocated,
as invoked by vvfat; we can likewise add assertions that the rest
of the stack does not have to worry about a NULL pnum.
Furthermore, this will also set the stage for a future cleanup: when
a caller does not care about which BDS owns an offset, it would be
nice to allow the driver to optimize things to not have to return
BDRV_BLOCK_OFFSET_VALID in the first place. In the case of fragmented
allocation (for example, it's fairly easy to create a qcow2 image
where consecutive guest addresses are not at consecutive host
addresses), the current contract requires bdrv_get_block_status()
to clamp *pnum to the limit where host addresses are no longer
consecutive, but allowing a NULL file means that *pnum could be
set to the full length of known-allocated data.

block: Convert bdrv_get_block_status_above() to bytes
We are gradually moving away from sector-based interfaces, towards
byte-based. In the common case, allocation is unlikely to ever use
values that are not naturally sector-aligned, but it is possible
that byte-based values will let us be more precise about allocation
at the end of an unaligned file that can do byte-based access.
Changing the name of the function from bdrv_get_block_status_above()
to bdrv_block_status_above() ensures that the compiler enforces that
all callers are updated. Likewise, since it a byte interface allows
an offset mapping that might not be sector aligned, split the mapping
out of the return value and into a pass-by-reference parameter. For
now, the io.c layer still assert()s that all uses are sector-aligned,
but that can be relaxed when a later patch implements byte-based
block status in the drivers.
For the most part this patch is just the addition of scaling at the
callers followed by inverse scaling at bdrv_block_status(), plus
updates for the new split return interface. But some code,
particularly bdrv_block_status(), gets a lot simpler because it no
longer has to mess with sectors. Likewise, mirror code no longer
computes s->granularity >> BDRV_SECTOR_BITS, and can therefore drop
an assertion about alignment because the loop no longer depends on
alignment (never mind that we don't really have a driver that
reports sub-sector alignments, so it's not really possible to test
the effect of sub-sector mirroring). Fix a neighboring assertion to
use is_power_of_2 while there.
For ease of review, bdrv_get_block_status() was tackled separately.

ppc: pnv: use generic cpu_model parsing
use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.
Beside of switching to generic infrastructure it solves several
issues.
* ppc_cpu_class_by_name() is used to deal with lower/upper case
and alias translations into actual cpu type, which fixes
'-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
usecases which error out with:
'invalid CPU model 'FOO' for powernv machine'
* allows to switch to lower-case typenames in pnv chip/core name
(by convention typnames should be lower-case)
* replace aliased names /power8, power9, .../ with exact cpu model
names (i.e. typenames should be stable but aliases might decide to
point to other cpu model withi family or changed by kvm). It will
also help to simplify pnv_chip/core code and get rid of dependency
on cpu_model parsing.

dirty-bitmap: Change bdrv_dirty_bitmap_*serialize*() to take bytes
Right now, the dirty-bitmap code exposes the fact that we use
a scale of sector granularity in the underlying hbitmap to anything
that wants to serialize a dirty bitmap. It's nicer to uniformly
expose bytes as our dirty-bitmap interface, matching the previous
change to bitmap size. The only caller to serialization is currently
qcow2-cluster.c, which becomes a bit more verbose because it is still
tracking sectors for other reasons, but a later patch will fix that
to more uniformly use byte offsets everywhere. Likewise, within
dirty-bitmap, we have to add more assertions that we are not
truncating incorrectly, which can go away once the internal hbitmap
is byte-based rather than sector-based.

qcow2: Switch store_bitmap_data() to byte-based iteration
Now that we have adjusted the majority of the calls this function
makes to be byte-based, it is easier to read the code if it makes
passes over the image using bytes rather than sectors.
iotests 165 was rather weak - on a default 64k-cluster image, where
bitmap granularity also defaults to 64k bytes, a single cluster of
the bitmap table thus covers (64*1024*8) bits which each cover 64k
bytes, or 32G of image space. But the test only uses a 1G image,
so it cannot trigger any more than one loop of the code in
store_bitmap_data(); and it was writing to the first cluster. In
order to test that we are properly aligning which portions of the
bitmap are being written to the file, we really want to test a case
where the first dirty bit returned by bdrv_dirty_iter_next() is not
aligned to the start of a cluster, which we can do by modifying the
test to write data that doesn't happen to fall in the first cluster
of the image.

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.

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.

The existing code will do the right thing for v7M cores because

won't attempt to trap, but when we start setting ARM_FEATURE_V8
for v8M cores the v8A handling of SCTLR.nTWE and .nTWI will not

This is the first piece of code which implements "switch to the

switch the stack pointers around, which is the only complicated
part of switching security state.
BLXNS is more complicated than just "BXNS but set the link register",
so we leave it for a separate commit.

target/s390x: use "core-id" for cpu number/address/id handling
Some time ago we discussed that using "id" as property name is not the
right thing to do, as it is a reserved property for other devices and
will not work with device_add.
Switch to the term "core-id" instead, and use it as an equivalent to
"CPU address" mentioned in the PoP. There is no such thing as cpu number,
so rename env.cpu_num to env.core_id. We use "core-id" as this is the
common term to use for device_add later on (x86 and ppc).
We can get rid of cpu->id now. Keep cpu_index and env->core_id in sync.
cpu_index was already implicitly used by e.g. cpu_exists(), so keeping
both in sync seems to be the right thing to do.
cpu_index will now no longer automatically get set via
cpu_exec_realizefn(). For now, we were lucky that both implicitly stayed
in sync.
Our new cpu property "core-id" can be a static property. Range checks can
be avoided by using the correct type and the "setting after realized"
check is done implicitly.
device_add will later need the reserved "id" property. Hotplugging a CPU
on s390x will then be: "device_add host-s390-cpu,id=cpu2,core-id=2".

configure: enable --s390-pgste linker option
KVM guests on s390 need a different page table layout than normal
processes (2kb page table + 2kb page status extensions vs 2kb page table
only). As of today this has to be enabled via the vm.allocate_pgste
sysctl.
Newer kernels (>= 4.12) on s390 check for an S390_PGSTE program header
and enable the pgste page table extensions in that case. This makes the
vm.allocate_pgste sysctl unnecessary. We enable this program header for
the s390 system emulation (qemu-system-s390x) if we build on s390
- for s390 system emulation
- the linker supports --s390-pgste (binutils >= 2.29)
- KVM is enabled
This will allow distributions to disable the global vm.allocate_pgste
sysctl, which will improve the page table allocation for non KVM
processes as only 2kb chunks are necessary.

vdi: make it thread-safe
The VirtualBox driver is using a mutex to order all allocating writes,
but it is not protecting accesses to the bitmap because they implicitly
happen under the AioContext mutex. Change this to use a CoRwlock
explicitly.

configure: Define NCURSES_WIDECHAR if we're using curses
We want the wide character functions from the ncurses header.
Unfortunately it doesn't provide them by default, but only
if either:
* NCURSES_WIDECHAR is defined (for ncurses 20111030 and up)
* _XOPEN_SOURCE/_XOPEN_SOURCE_EXTENDED are suitably defined
So far we have been implicitly relying on the latter, because
for GNU libc when we define _GNU_SOURCE this causes libc
to define the _XOPEN_SOURCE macros for us. Unfortunately
this doesn't work on all libcs, because some (like OSX and
musl libc) do not define _XOPEN_SOURCE when _GNU_SOURCE
is defined.
We can't fix this by defining _XOPEN_SOURCE ourselves, because
that also means "and don't provide any functions that aren't in
that standard", and not all libcs provide any way to override
that to also get the non-standard functions. In particular
FreeBSD has no such mechanism, and OSX's _DARWIN_C_SOURCE
doesn't reenable everything (for instance getpagesize()
is still not prototyped if _DARWIN_C_SOURCE and _XOPEN_SOURCE
are both defined).
So we have to define NCURSES_WIDECHAR. (This will only work
if your ncurses is at least 20111030, as older versions
don't honour this macro.)
