Instead of truncating replies, which is problematic, wait until the
client reads more data and frees bytes on the reply ring.
Do that by calling qemu_coroutine_yield(). The corresponding
qemu_coroutine_enter_if_inactive() is called from xen_9pfs_bh upon
receiving the next notification from the client.
We need to be careful to avoid races in case xen_9pfs_bh and the
coroutine are both active at the same time. In xen_9pfs_bh, wait until
either the critical section is over (ring->co == NULL) or until the
coroutine becomes inactive (qemu_coroutine_yield() was called) before
continuing. Then, simply wake up the coroutine if it is inactive.

Locking was introduced in QEMU 2.7 to address the deprecation of
readdir_r(3) in glibc 2.24. It turns out that the frontend code is
the worst place to handle a critical section with a pthread mutex:
the code runs in a coroutine on behalf of the QEMU mainloop and then
yields control, waiting for the fsdev backend to process the request
in a worker thread. If the client resends another readdir request for
the same fid before the previous one finally unlocked the mutex, we're
deadlocked.
This never bit us because the linux client serializes readdir requests
for the same fid, but it is quite easy to demonstrate with a custom
client.
A good solution could be to narrow the critical section in the worker
thread code and to return a copy of the dirent to the frontend, but
this causes quite some changes in both 9p.c and codir.c. So, instead
of that, in order for people to easily backport the fix to older QEMU
versions, let's simply use a CoMutex since all the users for this
sit in coroutines.

The command 0x00 is used by this model since its origin (commit
05ee37ebf6). In this commit the command is described with a
amusing '/* ??? */' comment, probably meaning 'FIXME'.
switch (cmd) {
case 0x00: /* ??? */
...
This comment survived 12 years because the 0x00 value is indeed
not specified by the CFI open standard (as of this commit).
The 'cmd' field is transfered during migration. To keep the
migration feature working with older QEMU version, we have to
take a lot of care with migrated field. We figured out it is
too late to remove a non-specified value from this model
(this would make migration review very complex). It is however
not too late to improve the documentation.
Add few comments to remember this is a special value related
to QEMU, and we won't find information about it on the CFI

For the typical case of stride > linesize (add padding) we error on the
safe side (calculated size is larger than actual size).
With stride < linesize (scanlines overlap) the calculated size is
smaller than the actual size though so our guest memory mapping might
end up being too small.
While being at it also fix ramfb_create_display_surface to use hwaddr

Same story as for object_property_add(): the only way
object_property_del() can fail is when the property with this name
does not exist. Since our property names are all hardcoded, failure
is a programming error, and the appropriate way to handle it is
passing &error_abort. Most callers do that, the commit before
previous fixed one that didn't (and got the error handling wrong), and
the two remaining exceptions ignore errors.

Devices may have component devices and buses.
Device realization may fail. Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).
When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far. If any of these unrealizes
failed, the device would be left in an inconsistent state. Must not
happen.
device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.
Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back? We'd have to
re-realize, which can fail. This design is fundamentally broken.
device_set_realized() does not roll back at all. Instead, it keeps
unrealizing, ignoring further errors.
It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.
bus_set_realized() does not roll back either. Instead, it stops
unrealizing.
Fortunately, no unrealize method can fail, as we'll see below.
To fix the design error, drop parameter @errp from all the unrealize
methods.
Any unrealize method that uses @errp now needs an update. This leads
us to unrealize() methods that can fail. Merely passing it to another
unrealize method cannot cause failure, though. Here are the ones that
do other things with @errp:
* virtio_serial_device_unrealize()
Fails when qbus_set_hotplug_handler() fails, but still does all the
other work. On failure, the device would stay realized with its
resources completely gone. Oops. Can't happen, because
qbus_set_hotplug_handler() can't actually fail here. Pass
&error_abort to qbus_set_hotplug_handler() instead.
* hw/ppc/spapr_drc.c's unrealize()
Fails when object_property_del() fails, but all the other work is
already done. On failure, the device would stay realized with its
vmstate registration gone. Oops. Can't happen, because
object_property_del() can't actually fail here. Pass &error_abort
to object_property_del() instead.
* spapr_phb_unrealize()
Fails and bails out when remove_drcs() fails, but other work is
already done. On failure, the device would stay realized with some
of its resources gone. Oops. remove_drcs() fails only when
chassis_from_bus()'s object_property_get_uint() fails, and it can't
here. Pass &error_abort to remove_drcs() instead.
Therefore, no unrealize method can fail before this patch.
device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool(). Can't drop @errp there, so pass
&error_abort.
We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors. Pass &error_abort instead.
Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.
One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().
Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

[Two semantic rebase conflicts resolved]
Both qdev_connect_gpio_out_named() and device_set_realized() put
objects without a parent into the "/machine/unattached/" orphanage.
qdev_connect_gpio_out_named() needs a lengthy comment to explain how
it works. It exploits that object_property_add_child() can fail only
when we got a parent already, and ignoring that error does what we
want. True. If it failed due to "duplicate property", we'd be in
trouble, but that would be a programming error.
device_set_realized() is cleaner: it checks whether we need a parent,
then calls object_property_add_child(), aborting on failure. No need
for a comment, and programming errors get caught.

QEMU's local 9pfs server passes through O_NOATIME from the client. If
the QEMU process doesn't have permissions to use O_NOATIME (namely, it
does not own the file nor have the CAP_FOWNER capability), the open will
fail. This causes issues when from the client's point of view, it
believes it has permissions to use O_NOATIME (e.g., a process running as
root in the virtual machine). Additionally, overlayfs on Linux opens
files on the lower layer using O_NOATIME, so in this case a 9pfs mount
can't be used as a lower layer for overlayfs (cf.
dabfe19719/vmtest/onoatimehack.c
and https://github.com/NixOS/nixpkgs/issues/54509).
Luckily, O_NOATIME is effectively a hint, and is often ignored by, e.g.,
network filesystems. open(2) notes that O_NOATIME "may not be effective
on all filesystems. One example is NFS, where the server maintains the

hw/tpm: fix usage of bool in tpm-tis.c
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Clean up wrong usage of FALSE and TRUE in places that use "bool" from stdbool.h.
FALSE and TRUE (with capital letters) are the constants defined by glib for
being used with the "gboolean" type of glib. But some parts of the code also use
TRUE and FALSE for variables that are declared as "bool" (the type from <stdbool.h>).

This is a boot stub that is similar to the code u-boot runs, allowing
the kernel to boot the secondary CPU.
u-boot works as follows:
1. Initialises the SMP mailbox area in the SCU at 0x1e6e2180 with default values
2. Copies a stub named 'mailbox_insn' from flash to the SCU, just above the
mailbox area
3. Sets AST_SMP_MBOX_FIELD_READY to a magic value to indicate the
secondary can begin execution from the stub
4. The stub waits until the AST_SMP_MBOX_FIELD_GOSIGN register is set to
a magic value
5. Jumps to the address in AST_SMP_MBOX_FIELD_ENTRY, starting Linux
Linux indicates it is ready by writing the address of its entrypoint
function to AST_SMP_MBOX_FIELD_ENTRY and the 'go' magic number to
AST_SMP_MBOX_FIELD_GOSIGN. The secondary CPU sees this at step 4 and
breaks out of it's loop.
To be compatible, a fixed qemu stub is loaded into the mailbox area. As
qemu can ensure the stub is loaded before execution starts, we do not
need to emulate the AST_SMP_MBOX_FIELD_READY behaviour of u-boot. The
secondary CPU's program counter points to the beginning of the stub,
allowing qemu to start secondaries at step four.
Reboot behaviour is preserved by resetting AST_SMP_MBOX_FIELD_GOSIGN
when the secondaries are reset.
This is only configured when the system is booted with -kernel and qemu
does not execute u-boot first.

The restrictions here (which are checked at pre-plug time) are PAPR

Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
The pseries machine does not support NVDIMM modules without label.
Attempting to do so, even if the overall block size is aligned with
256MB, will seg fault the guest kernel during NVDIMM probe. This
can be avoided by forcing 'label-size' to always be present for
sPAPR NVDIMMs.
The verification was put before the alignment check because the
presence of label-size affects the alignment calculation, so
it's not optimal to warn the user about an alignment error,
then about the lack of label-size, then about a new alignment
error when the user sets a label-size.

Currently, we can't properly handle unplug of NVLink2 devices, because we
don't have code to tear down their special memory resources. There's not
a lot of impetus to implement that: since hardware NVLink2 devices can't
be hot unplugged, the guest side drivers don't usually support unplug
anyway.
Therefore, simply prevent unplug of NVLink2 devices.

At the moment "ibm,client-architecture-support" ("CAS") is implemented
in SLOF and QEMU assists via the custom H_CAS hypercall which copies
an updated flatten device tree (FDT) blob to the SLOF memory which
it then uses to update its internal tree.
When we enable the OpenFirmware client interface in QEMU, we won't need
to copy the FDT to the guest as the client is expected to fetch
the device tree using the client interface.
This moves FDT rebuild out to a separate helper which is going to be
called from the "ibm,client-architecture-support" handler and leaves
writing FDT to the guest in the H_CAS handler.
This should not cause any behavioral change.

The guest can select the MMU mode by setting bits 0-1 of byte 24
in OV5 to to 0b00 for hash or 0b01 for radix. As required by the
architecture, we terminate the boot process if any other value
is found there.
The usual way to negotiate features in OV5 is basically ANDing
the bitfield provided by the guest and the bitfield of features
supported by QEMU, previously populated at machine init.
For some not documented reason, MMU is treated differently : bit 1
of byte 24 (the radix/hash bit) is cleared from the guest OV5 and
explicitely set in the final negotiated OV5 if radix was requested.
Since the only expected input from the guest is the radix/hash bit
being set or not, it seems more appropriate to handle this like we
do for XIVE.
Set the radix bit in spapr->ov5 at machine init if it has a chance
to work (ie. power9, either TCG or a radix capable KVM) and rely
exclusively on spapr_ovec_intersect() to set the radix bit in
spapr->ov5_cas.

We currently check if some capability in OV5 was removed by the guest
since the previous CAS, and we trigger a CAS reboot in that case. This
was required because it could call for a device-tree property or node
removal, that we didn't support until recently (see commit 6787d27b04
"spapr: add option vector handling in CAS-generated resets" for details).
Now that we render a full FDT at CAS and that SLOF is able to handle
node removal, we don't need to do a CAS reset in this case anymore.
Also, this check can only return true if the guest has already called
CAS since the last full system reset (otherwise spapr->ov5_cas is
empty). Linux doesn't do that so this can be considered as dead code
for the vast majority of existing setups.
Drop the check. Since the only use of the ov5_cas_old variable is
precisely the check itself, drop the variable as well.

Microsoft introduced this ACPI table to avoid Windows guests performing
various workarounds for device erratas. As the virtual device emulated
by VMM may not have the errata.
Currently, WAET allows hypervisor to inform guest about two
specific behaviors: One for RTC and the other for ACPI PM timer.
Support for WAET have been introduced since Windows Vista. This ACPI
table is also exposed by other common hypervisors by default, including:
VMware, GCP and AWS.
This patch adds WAET ACPI Table to QEMU.
We set "ACPI PM timer good" bit in "Emualted Device Flags" field to
indicate that the ACPI PM timer has been enhanced to not require
multiple reads to obtain a reliable value.
This results in improving the performance of Windows guests that use
ACPI PM timer by avoiding unnecessary VMExits caused by these multiple
reads.

vhost_user_set_mem_table() and vhost_user_set_mem_table_postcopy() have
gotten convoluted, and have some identical code.
This change moves the logic populating the VhostUserMemory struct and
fds array from vhost_user_set_mem_table() and
vhost_user_set_mem_table_postcopy() to a new function,
vhost_user_fill_set_mem_table_msg().

As per ACPI spec 6.3, Table 19-419 Object Conversion Rules, if
the Buffer Field <= to the size of an Integer (in bits), it will
be treated as an integer. Moreover, the integer size depends on
DSDT tables revision number. If revision number is < 2, integer
size is 32 bits, otherwise it is 64 bits. Current NVDIMM common
DSM aml code (NCAL) uses CreateField() for creating DSM output
buffer. This creates an issue in arm/virt platform where DSDT
revision number is 2 and results in DSM buffer with a wrong
size(8 bytes) gets returned when actual length is < 8 bytes.
This causes guest kernel to report,
"nfit ACPI0012:00: found a zero length table '0' parsing nfit"
In order to fix this, aml code is now modified such that it builds
the DSM output buffer in a byte by byte fashion when length is
smaller than Integer size.

With virtio-vga, pci bar are reordered. Bar #2 is used for compatibility
with stdvga. By default, bar #2 is used by virtio modern io bar.
This bar is the last one introduce in the virtio pci bar layout and it's
crushed by the virtio-vga reordering. So virtio-vga and
modern-pio-notify are incompatible because virtio-vga failed to
initialize with this option.
This fix sets the modern io bar to the bar #5 to avoid conflict.
