Call qemu_notify_event() after updating events. Otherwise, If we add

may be a delay before the event callback is actually triggered.
Those delays would in particular hurt performance during BIOS boot and
when the GRUB bootloader reads the kernel and initrd.
But first call out to the socket write functions directly, and only set up
the write event if the socket is full. This will happen very rarely and

virtio-blk: always enable VIRTIO_BLK_F_SCSI
VIRTIO_BLK_F_SCSI is supposed to mean whether the host can *parse*

that no one ever invoked QEMU with scsi=off.

- new QEMU, scsi=on -> old QEMU, scsi=on

virtio-blk: report non-zero status when failing SG_IO requests
Linux really looks only at scsi->errors for SG_IO requests; it does
not look at the virtio request status at all. Because of this, when
a SG_IO request is failed early with virtio_blk_req_complete(req,
VIRTIO_BLK_S_UNSUPP), without writing hdr.status, it will look like
a success to the guest.
This is their bug, but we can make it safe for older guests now by
forcing scsi->errors to have a non-zero value whenever a request
has to be failed.
But if we fix the bug in the guest driver, we will have another problem
because QEMU returns VIRTIO_BLK_S_IOERR if the status is non-zero, and
Linux translates that to -EIO. Rather, the guest should succeed the
request and pass the non-zero status via the userspace-provided SG_IO
structure. So, remove the case where virtio_blk_handle_scsi can
return VIRTIO_BLK_S_IOERR.

qemu-ga: guest-suspend: make the API synchronous
Currently, qemu-ga has a SIGCHLD handler that automatically reaps terminated
children processes. The idea is to avoid having qemu-ga commands blocked
waiting for children to terminate.
That approach has two problems:
1. qemu-ga is unable to detect errors in the child, meaning that qemu-ga
returns success even if the child fails to perform its task
2. if a command does depend on the child exit status, the command has to
play tricks to bypass the automatic reaper
Case 2 impacts the guest-suspend-* API, because it has to execute an external
program to check for suspend support. Today, to bypass the automatic reaper,
suspend code has to double fork and pass exit status information through a
pipe. Besides being complex, this is prone to race condition bugs. Indeed,
the current code does have such bugs.
Making the guest-suspend-* API synchronous (ie. by dropping the SIGCHLD
handler and calling waitpid() from commands) is a much simpler approach,
which fixes current race conditions bugs and enables commands to detect
errors in the child.
This commit does just that. There's a side effect though, guest-shutdown
will generate zombies if shutting down fails. This will be fixed by the
next commit.

qemu-ga: become_daemon(): reopen standard fds to /dev/null
This fixes a bug where qemu-ga doesn't suspend the guest because it
fails to detect suspend support even when the guest does support
suspend. This happens because of the way qemu-ga fds are managed in
daemon mode.
When starting qemu-ga with --daemon, become_daemon() will close all
standard fds. This will cause qemu-ga to end up with the following
fds (if started with 'qemu-ga --daemon'):
0 -> /dev/vport0p1
3 -> /run/qemu-ga.pid
Then a guest-suspend-* function is issued. They call bios_supports_mode(),
which will call pipe(), and qemu-ga's fd will be:
0 -> /dev/vport0p1
1 -> pipe:[16247]
2 -> pipe:[16247]
3 -> /run/qemu-ga.pid
bios_supports_mode() forks off a child and blocks waiting for the child
to write something to the pipe. The child, however, closes its reading
end of the pipe _and_ reopen all standard fds to /dev/null. This will
cause the child's fds to be:
0 -> /dev/null
1 -> /dev/null
2 -> /dev/null
3 -> /run/qemu-ga.pid
In other words, the child's writing end of the pipe is now /dev/null.
It writes there and exits. The parent process (blocked on read()) will
get an EOF and interpret this as "something unexpected happened in
the child, let's assume the guest doesn't support suspend". And suspend
will fail.
To solve this problem we have to reopen standard fds to /dev/null
in become_daemon(), instead of closing them.

target-i386: Defer MCE init
Commit
de024815e3b523addf58f1f79846b7fe74643678 (target-i386: QOM'ify
CPU init) moved mce_init() call from helper.c:cpu_x86_init() into
X86CPU's cpu.c:x86_cpu_initfn().
mce_init() checks for a family >= 6 though, so we could end up with a
sequence such as for -cpu somecpu,family=6:
x86_cpu_initfn => X86CPU::family == 5
mce_init => no-op
cpu_x86_register => X86CPU::family = 6
=> MCE unexpectedly not init'ed
or for -cpu someothercpu,family=5:
x86_cpu_initfn => X86CPU::family == 6
mce_init => init'ed
cpu_x86_register => X86CPU::family = 5
=> MCE unexpectedly init'ed
Therefore partially revert the above commit. To avoid moving
mce_init() back into helper.c, foresightedly move it into a
new x86_cpu_realize() function and, in lack of ObjectClass::realize,
call it directly from cpu_x86_init().
While at it, move the qemu_init_vcpu() call that used to follow
mce_init() in cpu_x86_init() into the new realizefn as well.

In addition, until commit c5bd4f3 -nodefaults would not disable the device

target-arm/cpu.h: Make cpu_init("nonexistent cpu") return NULL
The macro definition of cpu_init meant that if cpu_arm_init()
returned NULL this wouldn't result in cpu_init() itself returning
NULL. This had the effect that "-cpu foo" for some unknown CPU
name 'foo' would cause ARM targets to segfault rather than
generating a useful error message. Fix this by making cpu_init
a simple inline function.

kvm: Fix dirty tracking with large kernel page size
If the kernel page size is larger than TARGET_PAGE_SIZE, which
happens for example on ppc64 with kernels compiled for 64K pages,

stream: do not copy unallocated sectors from the base
Unallocated sectors should really never be accessed by the guest,
so there's no need to copy them during the streaming process.
If they are read by the guest during streaming, guest-initiated
copy-on-read will copy them (we're in the base == NULL case, which
enables copy on read). If they are read after we disconnect the
image from the base, they will read as zeroes anyway.

stream: fix ratelimiting corner case
This fixes inability to make progress in streaming if the quota is set
to less than the amount of data that an I/O operation has to write.
In this case, limit->dispatched + n will always be above the quota and,
due to the "goto retry" to recheck cancellation and allocation, streaming
will livelock.
This can be reproduced with "block_job_set_speed ide0-hd0 1b". Of course,
with this patch the requested limit will not be obeyed. That could be
done with another patch that caps is_allocated's n argument by the slice
quota.

stream: pass new base image format to bdrv_change_backing_file
When an image is modified to point to the new backing file, the backing
file format is set to NULL, which means auto-probe. This is wrong, in
fact it is a small security problem.
