windows cdrom cache flush (Stefano Stabellini)
Windows only flushes its cache of a CDROM if it gets a
SENSE_UNIT_ATTENTION CHECK_CONDITION response to a REQUEST_SENSE
command.
Make sure it does so after we change the CD.

pxb: Restrict to x86
The PCI Expander Bridge (PXB) device is essentially a hack to allow
different PCIe devices to be assigned to different NUMA nodes on x86. Each
PXB is sort-of a separate PCI host bridge, except that its config space
is shared with the config space of the main PCI host bridge, rather than
being independent.
This is only necessary if the platform doesn't (easily) allow truly
independent PCI host bridges. AFAIK that's just x86.
This patch makes it possible to configure PXB out of the build, and adjusts
the default configs so it's only included on x86 targets.

nvdimm: add 'unarmed' option
Currently the only vNVDIMM backend can guarantee the guest write
persistence is device DAX on Linux, because no host-side kernel cache
is involved in the guest access to it. The approach to detect whether
the backend is device DAX needs to access sysfs, which may not work
with SELinux.
Instead, we add the 'unarmed' option to device 'nvdimm', so that users
or management utils, which have enough knowledge about the backend,
can control the unarmed flag in guest ACPI NFIT via this option. The
guest Linux NVDIMM driver, for example, will mark the corresponding
vNVDIMM device read-only if the unarmed flag in guest NFIT is set.
The default value of 'unarmed' option is 'off' in order to keep the
backwards compatibility.

i386: Change X86CPUDefinition::model_id to const char*
It is valid to have a 48-character model ID on CPUID, however the
definition of X86CPUDefinition::model_id is char[48], which can
make the compiler drop the null terminator from the string.
If a CPU model happens to have 48 bytes on model_id, "-cpu help"
will print garbage and the object_property_set_str() call at
x86_cpu_load_def() will read data outside the model_id array.
We could increase the array size to 49, but this would mean the
compiler would not issue a warning if a 49-char string is used by
mistake for model_id.
To make things simpler, simply change model_id to be const char*,
and validate the string length using an assert() on
x86_register_cpudef_type().

s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG)
s390_cpu_virt_mem_rw() must always return, so callers can react on
an exception (e.g. see ioinst_handle_stcrw()).
However, for TCG we always have to exit the cpu loop (and restore the
cpu state before that) if we injected a program interrupt. So let's
introduce and use s390_cpu_virt_mem_handle_exc() in code that is not
purely KVM.
Directly pass the retaddr we already have available in these functions.

qcow2: check_errors are fatal
When trying to repair a dirty image, qcow2_check() may apparently

from continuing), but if check_errors in the result object is non-zero,

ppc: fix VTB migration
Migration of a system under stress (for example, with
"stress-ng --numa 2") triggers on the destination
some kernel watchdog messages like:
NMI watchdog: BUG: soft lockup - CPU#0 stuck for 3489660870s!
NMI watchdog: BUG: soft lockup - CPU#1 stuck for 3489660884s!
This problem appears with the changes introduced by
42043e4 spapr: clock should count only if vm is running
I think this commit only triggers the problem.
Kernel computes the soft lockup duration using the
Virtual Timebase register (VTB), not using the Timebase
Register (TBR, the one 42043e4 stops).
It appears VTB is not migrated, so this patch adds it in
the list of the SPRs to migrate, and fixes the problem.
For the migration, I've tested a migration from qemu-2.8.0 and
pseries-2.8.0 to a patched master (qemu-2.11.0-rc1). The received
VTB is 0 (as is it not initialized by qemu-2.8.0), but the value
seems to be ignored by KVM and a non zero VTB is used by the kernel.
I have no explanation for that, but as the original problem appears
only with SMP system under stress I suspect some problems in KVM
(I think because VTB is shared by all threads of a core).

build: remove use of MAKELEVEL optimization in submodule handling
The Makefile attempts to optimize the handling of submodules by using MAKELEVEL
to only check the submodule status when running from the top level make
invokation. This causes problems for people who are using a makefile of their
own to in turn invoke QEMU's makefile, as MAKELEVEL is already set to 1 (or
more) when QEMU's makefile runs.
This optimization should not really be needed, since the git-submodule.sh
script is already used to detect if a submodule update is required. This by
removing the MAKELEVEL check, we at most add an extra 'git-submodule.sh status'
call to each make level, the overhead of which is lost in noise of building
QEMU.

target-arm: Don't check for "Thumb2 or M profile" for not-Thumb1
The code which implements the Thumb1 split BL/BLX instructions
is guarded by a check on "not M or THUMB2". All we really need
to check here is "not THUMB2" (and we assume that elsewhere too,
eg in the ARCH(6T2) test that UNDEFs the Thumb2 insns).
This doesn't change behaviour because all M profile cores
have Thumb2 and so ARM_FEATURE_M implies ARM_FEATURE_THUMB2.
(v6M implements a very restricted subset of Thumb2, but we
can cross that bridge when we get to it with appropriate
feature bits.)

target-arm: Simplify insn_crosses_page()
Recent changes have left insn_crosses_page() more complicated
than it needed to be:
* it's only called from thumb_tr_translate_insn() so we know
for certain that we're looking at a Thumb insn
* the caller's check for dc->pc >= dc->next_page_start - 3
means that dc->pc can't possibly be 4 aligned, so there's
no need to check that (the check was partly there to ensure
that we didn't treat an ARM insn as Thumb, I think)
* we now have thumb_insn_is_16bit() which lets us do a precise
check of the length of the next insn, rather than opencoding
an inaccurate check
Simplify it down to just loading the first half of the insn
and calling thumb_insn_is_16bit() on it.

nvic: Handle v8M changes in nvic_exec_prio()
Update nvic_exec_prio() to support the v8M changes:
* BASEPRI, FAULTMASK and PRIMASK are all banked
* AIRCR.PRIS can affect NS priorities
* AIRCR.BFHFNMINS affects FAULTMASK behaviour
These changes mean that it's no longer possible to
definitely say that if FAULTMASK is set it overrides
PRIMASK, and if PRIMASK is set it overrides BASEPRI
(since if PRIMASK_NS is set and AIRCR.PRIS is set then
whether that 0x80 priority should take effect or the
priority in BASEPRI_S depends on the value of BASEPRI_S,
for instance). So we switch to the same approach used
by the pseudocode of working through BASEPRI, PRIMASK
and FAULTMASK and overriding the previous values if
needed.

limit to the number of VPs. In this case, Windows Server 2012
guest VMs may use more than 64 VPs, up to the maximum supported
number of processors applicable to the specific Windows
version being used.
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs
For compatibility, Let's introduce a new property for X86CPU,
named "x-hv-max-vps" as Eduardo's suggestion, and set it
to 0x40 before machine 2.10.
(The "x-" prefix indicates that the property is not supposed to
be a stable user interface.)

nvic: Add cached vectpending_prio state
Instead of looking up the pending priority
in nvic_pending_prio(), cache it in a new state struct
field. The calculation of the pending priority given
the interrupt number is more complicated in v8M with
the security extension, so the caching will be worthwhile.
This changes nvic_pending_prio() from returning a full
(group + subpriority) priority value to returning a group
priority. This doesn't require changes to its callsites
because we use it only in comparisons of the form
execution_prio > nvic_pending_prio()
and execution priority is always a group priority, so
a test (exec prio > full prio) is true if and only if
(execprio > group_prio).
(Architecturally the expected comparison is with the
group priority for this sort of "would we preempt" test;
we were only doing a test with a full priority as an
optimisation to avoid the mask, which is possible
precisely because the two comparisons always give the
same answer.)

qlit: Tighten QLit list vs QList comparison
We check that all members of the QLit list are also in the QList. We
neglect to check the other direction. Fix that.
While there, use QLIST_FOREACH_ENTRY() to simplify the code and break
the loop on the first mismatch.

block/qapi: Remove redundant NULL check to silence Coverity
When skipping implicit nodes in bdrv_block_device_info(), we know that
bs0 is always non-NULL; initially, because it's taken from a BdrvChild
and a BdrvChild never has a NULL bs, and after the first iteration
because implicit nodes always have a backing file.
Remove the NULL check and add an assertion that the implicit node does
indeed have a backing file.

usb: Fix build with newer gcc
gcc 7 is pickier about our sources:
hw/usb/bus.c: In function ‘usb_port_location’:
hw/usb/bus.c:410:66: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size between 0 and 15 [-Werror=format-truncation=]
snprintf(downstream->path, sizeof(downstream->path), "%s.%d",
^~
hw/usb/bus.c:410:9: note: ‘snprintf’ output between 3 and 28 bytes into a destination of size 16
snprintf(downstream->path, sizeof(downstream->path), "%s.%d",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
upstream->path, portnr);
~~~~~~~~~~~~~~~~~~~~~~~
But we know that there are at most 5 levels of USB hubs, with at
most two digits per level; that plus the separating dots means we
use at most 15 bytes (including trailing NUL) of our 16-byte field.
Adding an assertion to show gcc that we checked for truncation is
enough to shut up the false-positive warning.
Inspired by an idea by Dr. David Alan Gilbert <[email protected]>.

s390x/css: check ccw address validity
According to the PoP channel command words (CCW) must be doubleword
aligned and 31 bit addressable for format 1 and 24 bit addressable for
format 0 CCWs.
If the channel subsystem encounters a ccw address which does not satisfy
this alignment requirement a program-check condition is recognised.
The situation with 31 bit addressable is a bit more complicated: both the
ORB and a format 1 CCW TIC hold the address of (the rest of) the channel
program, that is the address of the next CCW in a word, and the PoP
mandates that bit 0 of that word shall be zero -- or a program-check
condition is to be recognized -- and does not belong to the field holding
the ccw address.
Since in code the corresponding fields span across the whole word (unlike
in PoP where these are defined as 31 bit wide) we can check this by
applying a mask. The 24 addressable case isn't affecting TIC because the
address is composed of a halfword and a byte portion (no additional zero
bit requirements) and just slightly complicates the ORB case where also
bits 1-7 need to be zero.
The same requirements (especially n-bit addressability) apply to the
ccw addresses generated while chaining.
Let's make our CSS implementation follow the AR more closely.

For a backend change, a number of ioctls has to be replayed to sync
the current setup of a frontend to a backend tty. This is hopefully
enough so we don't have to track, store and replay the whole original
control byte sequence.

checkpatch: should not use signal except for SIG_DFL or SIG_IGN
Using signal to establish a signal handler is not portable; on
SysV systems, the signal handler would be reset to SIG_DFL after
delivery, while BSD preserves the signal handler. Daniel Berrange
reported that (to complicate matters further) the signal system call
has SysV behavior, but glibc signal() actually calls the sigaction
system call to provide BSD behavior.
However, using signal() to set a signal's disposition to SIG_DFL
or SIG_IGN is portable and is a relatively common occurrence in
QEMU source code, so allow that.

The original ready < nhandles - 1 can be re-written as ready + 1 <

WAIT_OBJECT_0 was not subtracted from ready; it worked because
WAIT_OBJECT_0 is zero. After subtracting WAIT_OBJECT_0,
the result is the same condition that we are checking on the first
itteration of the for loop. This means we can remove the if statement
and let the for loop check the code.

virtio-9p: message header is 7-byte long
The 9p spec at http://man.cat-v.org/plan_9/5/intro reads:
"Each 9P message begins with a four-byte size field specify-
ing the length in bytes of the complete message including
the four bytes of the size field itself. The next byte is
the message type, one of the constants in the enumeration in
the include file <fcall.h>. The next two bytes are an iden-
tifying tag, described below."
ie, each message starts with a 7-byte long header.
The core 9P code already assumes this pretty much everywhere. This patch
does the following:
- makes the assumption explicit in the common 9p.h header, since it isn't
related to the transport
- open codes the header size in handle_9p_output() and hardens the sanity
check on the space needed for the reply message

xics: setup cpu at realize time
Until recently, spapr used to allocate ICPState objects for the lifetime
of the machine. They would only be associated to vCPUs in xics_cpu_setup()
when plugging a CPU core.
Now that ICPState objects have the same lifecycle as vCPUs, it is
possible to associate them during realization.
This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU
is passed as a property. Note that vCPU now needs to be realized first
for the IRQs to be allocated. It also needs to resetted before ICPState
realization in order to synchronize with KVM.
Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't
needed anymore and can be safely dropped.

target/s390x: rework PGM interrupt psw.addr handling
We can tell from the program interrupt code, whether a program interrupt
has to forward the address in the PGM new PSW
(suppressing/terminated/completed) to point at the next instruction, or
if it is nullifying and the PSW address does not have to be incremented.
So let's not modify the PSW address outside of the injection path and
handle this internally. We just have to handle instruction length
auto detection if no valid instruction length can be provided.
This should fix various program interrupt injection paths, where the
PSW was not properly forwarded.

sockets: improve error reporting if UNIX socket path is too long
The 'struct sockaddr_un' only allows 108 bytes for the socket
path.
If the user supplies a path, QEMU uses snprintf() to silently
truncate it when too long. This is undesirable because the user
will then be unable to connect to the path they asked for.
If the user doesn't supply a path, QEMU builds one based on
TMPDIR, but if that leads to an overlong path, it mistakenly
uses error_setg_errno() with a stale errno value, because
snprintf() does not set errno on truncation.
In solving this the code needed some refactoring to ensure we
don't pass 'un.sun_path' directly to any APIs which expect
NUL-terminated strings, because the path is not required to
be terminated.

target/s390x: fix COMPARE LOGICAL LONG EXTENDED
There are multiple issues with the COMPARE LOGICAL LONG EXTENDED
instruction:
- The test between the two operands is inverted, leading to an inversion
of the cc values 1 and 2.
- The address and length of an operand continue to be decreased after
reaching the end of this operand. These values are then wrong write
back to the registers.
- We should limit the amount of bytes to process, so that interrupts can
be served correctly.
At the same time rename dest into src1 and src into src3 to match the
operand names and make the code less confusing.

gluster: add support for PREALLOC_MODE_FALLOC
Add missing support for "preallocation=falloc" to the Gluster block
driver. This change bases its logic on that of block/file-posix.c and
removed the gluster_supports_zerofill() and qemu_gluster_zerofill()
functions in favour of #ifdef checks in an easy to read
switch-statement.
Both glfs_zerofill() and glfs_fallocate() have been introduced with
GlusterFS 3.5.0 (pkg-config glusterfs-api = 6). A #define for the
availability of glfs_fallocate() has been added to ./configure.

memory: tune last param of iommu_ops.translate()
This patch converts the old "is_write" bool into IOMMUAccessFlags. The
difference is that "is_write" can only express either read/write, but
sometimes what we really want is "none" here (neither read nor write).
Replay is an good example - during replay, we should not check any RW
permission bits since thats not an actual IO at all.

sockets: Limit SocketAddressLegacy to external interfaces
SocketAddressLegacy is a simple union, and simple unions are awkward:
they have their variant members wrapped in a "data" object on the
wire, and require additional indirections in C. SocketAddress is the
equivalent flat union. Convert all users of SocketAddressLegacy to
SocketAddress, except for existing external interfaces.

pseries: Don't expose PCIe extended config space on older machine types
bb9986452 "spapr_pci: Advertise access to PCIe extended config space"
allowed guests to access the extended config space of PCI Express devices
via the PAPR interfaces, even though the paravirtualized bus mostly acts
like plain PCI.
However, that patch enabled access unconditionally, including for existing
machine types, which is an unwise change in behaviour. This patch limits
the change to pseries-2.9 (and later) machine types.

disas/microblaze: Avoid unintended sign extension
In read_insn_microblaze() we assemble 4 bytes into an 'unsigned
long'. If 'unsigned long' is 64 bits and the high byte has its top
bit set, then C's implicit conversion from 'unsigned char' to 'int'
for the shift will result in an unintended sign extension which sets
the top 32 bits in 'inst'. Add casts to prevent this. (Spotted by
Coverity, CID 1005401.)

machine: Convert abstract typename on compat_props to subclass names
Original problem description by Greg Kurz:
> Since commit "9a4c0e220d8a hw/virtio-pci: fix virtio
> behaviour", passing -device virtio-blk-pci.disable-modern=off
> has no effect on 2.6 machine types because the internal
> virtio-pci.disable-modern=on compat property always prevail.
The same bug also affects other abstract type names mentioned on
compat_props by machine-types: apic-common, i386-cpu, pci-device,
powerpc64-cpu, s390-skeys, spapr-pci-host-bridge, usb-device,
virtio-pci, x86_64-cpu.
The right fix for this problem is to make sure compat_props and
-global options are always applied in the order they are
registered, instead of reordering them based on the type
hierarchy. But changing the ordering rules of -global is risky
and might break existing configurations, so we shouldn't do that
on a stable branch.
This is a temporary hack that will work around the bug when
registering compat_props properties: if we find an abstract class
on compat_props, register properties for all its non-abstract
subtypes instead. This will make sure -global won't be overridden
by compat_props, while keeping the existing ordering rules on
-global options.
Note that there's one case that won't be fixed by this hack:
"-global spapr-pci-vfio-host-bridge.<option>=<value>" won't be
able to override compat_props, because spapr-pci-host-bridge is
not an abstract class.

This seems to have worked just fine so far on weakly-ordered
architectures, but I don't see anything that prevents the
reordering from:
store 1 to exit_request
store 1 to tcg_exit_req
load tcg_exit_req
store 0 to tcg_exit_req
load exit_request
store 0 to exit_request
store 1 to exit_request
store 1 to tcg_exit_req
to this:
store 1 to exit_request
store 1 to tcg_exit_req
load tcg_exit_req
load exit_request
store 1 to exit_request
store 1 to tcg_exit_req
store 0 to tcg_exit_req
store 0 to exit_request
therefore losing a request. It's possible that other memory barriers
(e.g. in rcu_read_unlock) are hiding it, but better safe than
sorry.

coroutine-lock: reschedule coroutine on the AioContext it was running on
As a small step towards the introduction of multiqueue, we want
coroutines to remain on the same AioContext that started them,
unless they are moved explicitly with e.g. aio_co_schedule. This patch
avoids that coroutines switch AioContext when they use a CoMutex.
For now it does not make much of a difference, because the CoMutex
is not thread-safe and the AioContext itself is used to protect the
CoMutex from concurrent access. However, this is going to change.

target/ppc: Add Instruction Authority Mask Register Check
The instruction authority mask register (IAMR) can be used to restrict
permissions for instruction fetch accesses on a per key basis for each
of 32 different key values. Access permissions are derived based on the
specific key value stored in the relevant page table entry.
The IAMR was introduced in, and is present in processors since, POWER8
(ISA v2.07). Thus introduce a function to check access permissions based
on the pte key value and the contents of the IAMR when handling a page
fault to ensure sufficient access permissions for an instruction fetch.
A hash pte contains a key value in bits 2:3|52:54 of the second double word
of the pte, this key value gives an index into the IAMR which contains 32
2-bit access masks. If the least significant bit of the 2-bit access mask
corresponding to the given key value is set (IAMR[key] & 0x1 == 0x1) then
the instruction fetch is not permitted and an ISI is generated accordingly.
While we're here, add defines for the srr1 bits to be set for the ISI for
clarity.
e.g.
pte:
dw0 [XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]
dw1 [XX01XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX010XXXXXXXXX]
^^ ^^^
key = 01010 (0x0a)
IAMR: [XXXXXXXXXXXXXXXXXXXX01XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]
^^
Access mask = 0b01
Test access mask: 0b01 & 0x1 == 0x1
Least significant bit of the access mask is set, thus the instruction fetch
is not permitted. We should generate an instruction storage interrupt (ISI)
with bit 42 of SRR1 set to indicate access precluded by virtual page class
key protection.

hw/i386: check if nvdimm is enabled before plugging
The missing of 'nvdimm' in the machine type option '-M' means NVDIMM
is disabled. QEMU should refuse to plug any NVDIMM device in this case
and report the misconfiguration.
The behavior of NVDIMM on unsupported platform (HW/FW) is vendor
specific. For some vendors, it's undefined and the platform may do
anything. Thus, I think QEMU is free to choose the implementation.
Aborting QEMU (i.e. refusing to boot) is the easiest one.
