If DMA's owning thread cancels the IO while the bounce buffer's owning thread
is notifying the "cpu client list", a use-after-free happens:
continue_after_map_failure dma_aio_cancel

aio_bh_new
qemu_bh_delete
qemu_bh_schedule (use after free)
Also, the old code doesn't run the bh in the right AioContext.

Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread. There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec. Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.
Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.
This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.
User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

Users of virtio-serial may want to know when a port becomes writable. A
port can stop accepting writes if the guest port is open but not being
read from. In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.
When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.
This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.
This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.
This removes unused qemu_time_start and tlb_flush_time.

More and more virtual machine specifics between kvm and qemu will be
transferred with vm attributes.
So we encapsulate the common logic in a generic function.
Additionally we need only to check during initialization if kvm supports
virtual machine attributes.

This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.
Note that the code generating backends still manipulate labels as int.
With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.
Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg. Unfortunately, this only works
if the second argument is a local or thread-local variable.
If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims. If the latter happens, the race can
happen. A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison. This causes a wrong
failure, and then two threads are using "elm" at the same time. In the
case discovered by Christian, the sequence was likely something like this:
thread 1 | thread 2
QSLIST_INSERT_HEAD_ATOMIC |
atomic_cmpxchg succeeds |
elm added to list |
| steal release_pool
| QSLIST_REMOVE_HEAD
| elm removed from list
| ...
| QSLIST_INSERT_HEAD_ATOMIC
| (overwrites sle_next)
spurious failure |
atomic_cmpxchg succeeds |
elm added to list again |
|
steal release_pool |
QSLIST_REMOVE_HEAD |
elm removed again |
The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:
- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
memory was 16G just to err on the safe side (the host has 64G, but hey
at least you need no s390)
- the guest has 24 null-aio virtio-blk devices using dataplane
(-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
-device virtio-blk-pci,iothread=ioN,drive=blkN)
- the guest also has a single network interface. It's only doing loopback
tests so slirp vs. tap and the model doesn't matter.
- the guest is running fio with the following script:

QEMU wants to use virtio scsi structures with

This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.
blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise

Three kinds of callers:
1. On failure, report the error and abort
Passing &error_abort does the job. No functional change.
2. On failure, report the error and exit()
This is qdev_prop_set_drive_nofail(). Error reporting moves from
qdev_prop_set_drive() to its caller. Because hiding away the error
in the monitor right before exit() isn't helpful, replace
qerror_report_err() by error_report_err(). Shouldn't make a
difference, because qdev_prop_set_drive_nofail() should never be
used in QMP context.
3. On failure, report the error and recover
This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error
reporting and freeing the error object moves from
qdev_prop_set_drive() to its callers.
Because usb_msd_init() can't run in QMP context, replace
qerror_report_err() by error_report_err() there.
No functional change.
scsi_bus_legacy_add_drive() calling qerror_report_err() is of
course inappropriate, but this commit merely makes it more obvious.

The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:
* RTAS calls are received in spapr_pci.c, sanity check is done
there.
* RTAS handlers handle what they can. If there is something it
cannot handle and the corresponding sPAPRPHBClass callback is
defined, it is called.
* Those callbacks are only implemented for VFIO now. They do ioctl()
to the IOMMU container fd to complete the calls. Error codes from
that ioctl() are transferred back to the guest.

The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.
This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused
"rtc_offset" field from the new version of the spapr migration
stream

At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code. This
becomes inconvenient as we extend it in various ways.
This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).

The virtual RTC time is used in two places in the pseries machine. First
is in the RTAS get-time-of-day function which returns the RTC time to the
guest. Second is in the spapr events code which is used to timestamp
event messages from the hypervisor to the guest.
Currently both call qemu_get_timedate() directly, but we want to change
that so we can properly handle the various -rtc options. In preparation,
create a helper function to return the virtual RTC time.

The mc146818rtc driver exposes the current RTC date and time via the "date"

do this.
This patch introduces new helpers to the QOM core to expose struct tm

At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.
SLOF change is required to utilize this extension.

pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.
This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.

The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.

Disabling MMAP support uses the slower read/write accesses but allows to

Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).
In all this time, nobody reported the loss. I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.
Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.

Even if the caller has both the old and the new AioContext's, there can
be a deadlock, due to the leading bdrv_drain_all.
Suppose there are four io threads (A, B, A0, B0) with A and B owning a
BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and
B wants to move bs_b to B0, at the same time:
iothread A iothread B

aio_context_acquire(A0) /* OK */ aio_context_acquire(B0) /* OK */

-> acquire A /* OK */ -> acquire A /* blocked */
-> acquire B /* blocked */ -> acquire B

Deadlock happens because A is waiting for B, and B is waiting for A.

img_convert() and img_amend() use qemu_opts_do_parse(), which reports
errors with qerror_report_err(). Its error messages aren't helpful
here, the caller reports one that actually makes sense. Reproducer:
$ qemu-img convert -o backing_format=raw in.img out.img
qemu-img: Invalid parameter 'backing_format'
qemu-img: Invalid options for file format 'raw'
To fix, propagate errors through qemu_opts_do_parse(). This lifts the
error reporting into callers. Drop it from img_convert() and
img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create().

it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.
Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.
Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.
impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.
PS:
Later Windows editions seem to be fine with above
conditions.

Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

Add virtio_{add,clear}_feature helper functions for manipulating a
feature bits variable. This has some benefits over open coding:
- add check that the bit is in a sane range
- make it obvious at a glance what is going on
- have a central point to change when we want to extend feature bits
Convert existing code manipulating features to use the new helpers.

The only user of this function was virtio-ccw, and it should use
virtio_set_features() like everybody else: We need to make sure
that bad features are masked out properly, which this function did
not do.

/i.e. matches ACPI tables blob in source/
if guest is migrated during RSDP reading or
has been already shadowed by firmware.
Fix applies only to new machine types starting
from 2.3, so it won't break migration for old
machine types.

Memory and CPU hot unplug are both asynchronous procedures.
When the unplug operation happens, unplug request cb is called first.
And when guest OS finished handling unplug, unplug cb will be called
to do the real removal of device.
This patch adds hotunplug cb to ich9, which memory and CPU
hot unplug will use it.

-global lets you set a nice booby-trap for yourself:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
Not nice. Until commit 3196270 we even abort()ed.
The same error triggers if you manage to screw up a machine type's
compat_props. To demonstrate, change HW_COMPAT_2_1's entry to
.driver = "usb-mouse",\
.property = "usb_version",\
.value = "1", \
Then run
$ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
One of our creatively cruel error messages.
Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.
But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user. Looks like this:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
(qemu)
This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().
You could argue that the error should make device_add fail. Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.
