init_in_iov_from_pdu might not be able to allocate the full buffer size
requested, which comes from the client and could be larger than the
transport has available at the time of the request. Specifically, this
can happen with read operations, with the client requesting a read up to
the max allowed, which might be more than the transport has available at
the time.
Today the implementation of init_in_iov_from_pdu throws an error, both
Xen and Virtio.
Instead, change the V9fsTransport interface so that the size becomes a
pointer and can be limited by the implementation of
init_in_iov_from_pdu.
Change both the Xen and Virtio implementations to set the size to the
size of the buffer they managed to allocate, instead of throwing an
error. However, if the allocated buffer size is less than P9_IOHDRSZ
(the size of the header) still throw an error as the case is unhandable.

[groug: fix 32-bit build]
Signed-off-by: Greg Kurz <groug@kaod.org>
local_unlinkat_common() is supposed to always return -1 on error.
This is being done by jumps to the 'err_out' label, which is
a 'return ret' call, and 'ret' is initialized with -1.
Unfortunately there is a condition in which the function will
return 0 on error: in a case where flags == AT_REMOVEDIR, 'ret'
will be 0 when reaching
map_dirfd = openat_dir(...)
And, if map_dirfd == -1 and errno != ENOENT, the existing 'err_out'
jump will execute 'return ret', when ret is still set to zero
at that point.
This patch fixes it by changing all 'err_out' labels by
'return -1' calls, ensuring that the function will always
return -1 on error conditions. 'ret' can be left unintialized
since it's now being used just to store the result of 'unlinkat'
calls.

Migration is silently broken now with x2apic config like this:
-smp 200,maxcpus=288,sockets=2,cores=72,threads=2 \
-device intel-iommu,intremap=on,eim=on
After migration, the guest kernel could hang at anything, due to
x2apic bit not migrated correctly in IA32_APIC_BASE on some vcpus, so
any operations related to x2apic could be broken then (e.g., RDMSR on
x2apic MSRs could fail because KVM would think that the vcpu hasn't
enabled x2apic at all).
The issue is that the x2apic bit was never applied correctly for vcpus
whose ID > 255 when migrate completes, and that's because when we
migrate APIC we use the APICCommonState.id as instance ID of the
migration stream, while that's too short for x2apic.
Let's use the newly introduced initial_apic_id for that.

I've got a case where usbredir_write manages to call back into itself
via spice; this patch causes the recursion to fail (0 bytes) the write;
this seems to avoid the deadlock I was previously seeing.
I can't say I fully understand the interaction of usbredir and spice;
but there are a few similar guards in spice and usbredir
to catch other cases especially onces also related to spice_server_char_device_wakeup
This case seems to be triggered by repeated migration+repeated
reconnection of the viewer; but my debugging suggests the migration
finished before this hits.
The backtrace of the hang looks like:
reds_handle_ticket
reds_handle_other_links
reds_channel_do_link
red_channel_connect
spicevmc_connect
usbredir_create_parser
usbredirparser_do_write
usbredir_write
qemu_chr_fe_write

qemu_chr_write_buffer

spice_server_char_device_wakeup

usbredirparser_do_write
usbredir_write
qemu_chr_fe_write
qemu_chr_write
qemu_chr_write_buffer
qemu_mutex_lock_impl
and we fail as we lang through qemu_chr_write_buffer's lock
twice.

Here's another pull request for qemu-5.0 of ppc related changes.
Highlights are:
* First parts of support for POWER Secure VMs
* Rework to clean up how we pass context information to the various
components of the pnv machine (reduces usage of qdev_get_machine())
* Assorted cleanups and bugfixes

Provides a blocking call to read a character from the console using
semihosting.chardev, if specified. This takes some careful command
line options to use stdio successfully as the serial ports, monitor
and semihost all want to use stdio. Here's a sample set of command
line options which share stdio between semihost, monitor and serial
ports:
qemu \
-chardev stdio,mux=on,id=stdio0 \
-serial chardev:stdio0 \
-semihosting-config enable=on,chardev=stdio0 \
-mon chardev=stdio0,mode=readline
This creates a chardev hooked to stdio and then connects all of the
subsystems to it. A shorter mechanism would be good to hear about.

The Chardev events are listed in the QEMUChrEvent enum.
By using the enum in the IOEventHandler typedef we:
- make the IOEventHandler type more explicit (this handler
process out-of-band information, while the IOReadHandler
is in-band),
- help static code analyzers.
This patch was produced with the following spatch script:
@match@
expression backend, opaque, context, set_open;
identifier fd_can_read, fd_read, fd_event, be_change;
@@
qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event,
be_change, opaque, context, set_open);

identifier opaque, event;
identifier match.fd_event;
@@
static
-void fd_event(void *opaque, int event)
+void fd_event(void *opaque, QEMUChrEvent event)
{
...
}
Then the typedef was modified manually in
include/chardev/char-fe.h.

blk_getlength() returns an int64_t but the result is stored in a
uint32_t. Errors (negative values) won't be caught by the check in
pnv_pnor_realize() and blk_blockalign() will allocate a very large
buffer in such cases.

The proper way to do that would be to use device_class_set_parent_realize(),
but defining a Pnv8PsiClass and a Pnv9PsiClass types with a parent_realize
pointer adds a fair amount of code. Calling pnv_psi_realize() explicitely
is fine for now.
This should probably be achieved with a device realize hook in the
PSI base class and device_class_set_parent_realize() in the children
classes.

And call it from a QEMU reset handler. This allows each PNV child class to
override the reset hook if needed, eg. POWER8 doesn't but POWER9 does.

but defining a Pnv8PsiClass and a Pnv9PsiClass types with a parent_reset

A subsequent patch will consolidate the call to qemu_register_reset() in
