When monitor_flush() is invoked repeatedly outside the monitor_unblocked()
callback, for example from tlb_info() -> ... -> print_pte(), several
watches may be added for the same event.
This is no problem per se because the extra monitor_unblocked() callbacks
are harmless if mon->outbuf is empty, the watches will be removed
gradually. However a big number of watches can grow "gpollfds" without
limit in glib_pollfds_fill(), triggering a -1/EINVAL condition in
g_poll().
Keep at most one such watch, by following the pattern observable in eg.
commits c874ea97 and c3d6b96e. The change has no effect when
monitor_unblocked() calls monitor_flush() (when the watch can either be
removed or renewed 1-for-1), but non-callback contexts won't create an
additional watch when the monitor already has one.

io_channel_send() could lose such bytes before.
Furthermore, the (status == G_IO_STATUS_EOF) condition used to evaluate to

In qmp-marshal.c the dealloc visitor calls use the same errp
pointer of the input visitor calls. This means that if any of
the input visitor calls fails, then the dealloc visitor will
return early, before freeing the object's memory.
Here's an example, consider this code:
int qmp_marshal_input_block_passwd(Monitor *mon, const QDict *qdict, QObject **ret)
{
[...]
char * device = NULL;
char * password = NULL;
mi = qmp_input_visitor_new_strict(QOBJECT(args));
v = qmp_input_get_visitor(mi);
visit_type_str(v, &device, "device", errp);
visit_type_str(v, &password, "password", errp);
qmp_input_visitor_cleanup(mi);
if (error_is_set(errp)) {
goto out;
}
qmp_block_passwd(device, password, errp);
out:
md = qapi_dealloc_visitor_new();
v = qapi_dealloc_get_visitor(md);
visit_type_str(v, &device, "device", errp);
visit_type_str(v, &password, "password", errp);
qapi_dealloc_visitor_cleanup(md);
[...]
return 0;
}
Consider errp != NULL when the out label is reached, we're going
to leak device and password.
This patch fixes this by always passing errp=NULL for dealloc
visitors, meaning that we always try to free them regardless of
any previous failure. The above example would then be:
out:
md = qapi_dealloc_visitor_new();
v = qapi_dealloc_get_visitor(md);
visit_type_str(v, &device, "device", NULL);
visit_type_str(v, &password, "password", NULL);
qapi_dealloc_visitor_cleanup(md);

Add support for error containment when a VFIO device assigned to a KVM
guest encounters an error. This is for PCIe devices/drivers that support AER
functionality. When the host OS is notified of an error in a device either
through the firmware first approach or through an interrupt handled by the AER
root port driver, the error handler registered by the vfio-pci driver gets
invoked. The qemu process is signaled through an eventfd registered per
VFIO device by the qemu process. In the eventfd handler, qemu decides on
what action to take. In this implementation, guest is brought down to
contain the error.
The kernel patches for the above functionality has been already accepted.
This is a refresh of the QEMU patch which was reviewed earlier.
http://marc.info/?l=linux-kernel&m=136281557608087&w=2
This patch has the same contents and has been built after refreshing
to latest upstream and after the linux headers have been updated in qemu.
- Create eventfd per vfio device assigned to a guest and register an
event handler
- This fd is passed to the vfio_pci driver through the SET_IRQ ioctl
- When the device encounters an error, the eventfd is signalled
and the qemu eventfd handler gets invoked.
- In the handler decide what action to take. Current action taken
is to stop the guest.

Old qemu versions required that 1st s/g entry is the header.
Since QEMU 1.5, patchset titled "virtio-net: iovec handling cleanup"
removed this limitation but a feature bit is needed so guests know it's
safe to lay out header differently.
This patch applies on top and adds such a feature bit to QEMU.
It is set by default for virtio-net.
virtio net header inline with the data is beneficial
for latency and small packet bandwidth - guest driver
code utilizing this feature has been acked but missed 3.11
by a narrow margin, it's pending for 3.12.
This feature bit is cleared by default when compatibility with old
machine types is requested.
Other performance-sensitive devices (blk and scsi)
don't yet support arbitrary s/g layouts, so
we only set this bit for virtio-net for now.
There are plans to allow arbitrary layouts there, but
no code has been posted yet.

Currently macvtap based macvlan device is working in promiscuous
mode, we want to implement mac-programming over macvtap through
Libvirt for better performance.
Design:
QEMU notifies Libvirt when rx-filter config is changed in guest,
then Libvirt query the rx-filter information by a monitor command,
and sync the change to macvtap device. Related rx-filter config
of the nic contains main mac, rx-mode items and vlan table.
This patch adds a QMP event to notify management of rx-filter change,
and adds a monitor command for management to query rx-filter
information.
Test:
If we repeatedly add/remove vlan, and change macaddr of vlan
interfaces in guest by a loop script.
Result:
The events will flood the QMP client(management), management takes
too much resource to process the events.
Event_throttle API (set rate to 1 ms) can avoid the events to flood
QMP client, but it could cause an unexpected delay (~1ms), guests
guests normally expect rx-filter updates immediately.
So we use a flag for each nic to avoid events flooding, the event
is emitted once until the query command is executed. The flag
implementation could not introduce unexpected delay.
There maybe exist an uncontrollable delay if we let Libvirt do the
real change, guests normally expect rx-filter updates immediately.
But it's another separate issue, we can investigate it when the
work in Libvirt side is done.
Michael S. Tsirkin: tweaked to enable events on start
Michael S. Tsirkin: fixed not to crash when no id

LPAE CPUs have more potentially valid bits in the TTBCR, and so the
simple masking out of invalid bits is no longer sufficient to obtain
the base address width field of the register, which is what we use to
precalculate c2_mask and c2_base_mask. Explicitly extract the
relevant register field rather than simply shifting by the register
value.
This bug would have had no ill effects in practice, since if the
EAE bit (TTBCR bit 31) is set then we don't use the precalculated
masks, and if EAE is zero then bits 30..3 are all UNK/SBZP, so
well-behaved guests won't set them. However the shift is undefined
behaviour, so we should avoid it.
