Commit 9ef2e93f introduced the concept of tagging ATAPI commands as
NONDATA, but this introduced a regression for certain commands better
described as CONDDATA. read_cd is such a command that both requires
a non-zero BCL if a transfer size is set, but is perfectly content to
accept a zero BCL if the transfer size is 0.
This test adds a regression test for the case where BCL and nb_sectors
are both 0.
Flesh out the CDROM tests by:
(1) Allowing the test to specify a BCL
(2) Allowing the buffer comparison test to compare a 0-size buffer
(3) Fix the BCL specification in libqos (It is LE, not BE)
(4) Add a nice human-readable message for future SCSI command additions

We make sure that the size is aligned to sector length to prevent any
round ups. Otherwise we could end up reading/writing data outside the
area specified by user. This is only needed when user supplies the size
option to avoid any surprises. It is not necessary when only offset is
set.
More over, the check made it difficult to use the offset option without
size option. The check puts unneeded restriction on the offset which had
to be aligned too. Because bdrv_getlength() returns aligned value having
unaligned offset would make the check fail.

When only offset is specified but no size and the offset is greater than
the real size of the containing device an overflow occurs when parsing
the options. This overflow is harmless because we do check for this
exact situation little bit later, but it leads to an error message with
weird values. It is better to do the check is sooner and prevent the

A job ID is always required in order to create a block job on a
non-root node. The default ID (obtained with bdrv_get_device_name())
is otherwise empty in this scenario and the job cannot be created.
The HMP block_stream command doesn't set a job ID and therefore it
doesn't allow streaming to intermediate nodes. One solution is to add
an extra parameter to set a job ID. The other solution is to simply
use the node name passed to block_stream as job ID. This won't work
if it's automatically generated (because it contains a '#') but is
otherwise simple enough for all other cases.
This way 'block_stream node3' will create a job with the ID 'node3'
and the good old 'block_stream virtio0' will keep the previous
behaviour and use 'virtio0' for the job ID.

The printscreen/sysrq and pause/break keys currently don't work for guests
using -usbdevice keyboard when accessed through vnc with a gtk-vnc based
client.
The reason for this is a mismatch between gtk-vnc and qemu in how these keys
should be mapped to XT keycodes.
On the original IBM XT these keys behaved differently than other keys.
Quoting from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html:
The keys PrtSc/SysRq and Pause/Break are special. The former produces
scancode e0 2a e0 37 when no modifier key is pressed simultaneously, e0 37
together with Shift or Ctrl, but 54 together with (left or right) Alt. (And
one gets the expected sequences upon release. But see below.) The latter
produces scancode sequence e1 1d 45 e1 9d c5 when pressed (without modifier)
and nothing at all upon release. However, together with (left or right)
Ctrl, one gets e0 46 e0 c6, and again nothing at release. It does not
repeat.
Gtk-vnc supports the 'QEMU Extended Key Event Message' RFB extension to send
raw XT keycodes directly to qemu, but the specification doesn't explicitly
specify how to map such long/complicated keycode sequences. From the spec
(https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#qemu-extended-key-event-message)
The keycode is the XT keycode that produced the keysym. An XT keycode is an
XT make scancode sequence encoded to fit in a single U32 quantity. Single
byte XT scancodes with a byte value less than 0x7f are encoded as is.
2-byte XT scancodes whose first byte is 0xe0 and second byte is less than
0x7f are encoded with the high bit of the first byte set
hid.c currently expects the keycode sequence with shift/ctl for sysrq (e0 37
-> 0xb7 in RFB), whereas gtk-vnc uses the sequence with alt (0x54).
Likewise, hid.c expects the code without modifiers (e1 1d 45 -> 0xc5 in
RFB), whereas gtk-vnc sends the keycode sequence with ctrl for pause (e0 46
-> 0xc6 in RFB).
See keymaps.cvs in gtk-vnc for the mapping used:
https://git.gnome.org/browse/gtk-vnc/tree/src/keymaps.csv#n150
Now, it isn't obvious to me which sequence is really "right", but as the
0x54/0xc6 keycodes are currently unused in hid.c, supporting both seems like
the pragmatic solution to me. The USB HID keyboard boot protocol used by
hid.c doesn't have any other mapping applicable to these keys.
The other guest keyboard interfaces (ps/2, virtio, ..) are not affected,
because they handle these keys differently.

Commit 7d3123e converted a single read_sync() into a while loop
that assumed that read_sync() would either make progress or give
an error. But when the server hangs up early, the client sees
EOF (a read_sync() of 0) and never makes progress, which in turn
caused qemu-iotest './check -nbd 83' to go into an infinite loop.
Rework the loop to accomodate reads cut short by EOF.

With current code, pid file is open after various
sockets, chardevs, fsdevs and the like. This causes
interesting effects, for example when monitor is a

running, new qemu first "damages" the socket and
next complain that it can't acquire the pid file and
exits, making running qemu unreachable.
Move pid file creation earlier, right after the call
to os_daemonize(), where we know our process id (pid).

Commit 3ff2f67a changed bdrv_co_flush() so that no flush is issues if
the image hasn't been dirtied since the last flush. This is not quite
correct: The condition should be that the image hasn't been dirtied
since the last _successful_ flush. This patch changes the logic
accordingly.
Without this fix, subsequent bdrv_co_flush() calls would return success
without actually doing anything even though the image is still dirty.
The difference is visible in some blkdebug test cases where error
messages incorrectly disappeared after commit 3ff2f67a.

Commit 14e6fe12a ("*_run_on_cpu: introduce run_on_cpu_data type")
attempted to convert all users of run_on_cpu to use the new
run_on_cpu_data type. It missed to change the called sigp_* routines,
however. Fix that.

If the guest attempts to talk to a nonexistent device over i2c,
the i2c_start_transfer() function will return non-zero, indicating
that the bus is signalling a NACK. Similarly, if the i2c_send()
function returns nonzero then the target device returned a NACK.
Handle this possibility in the bitbang_i2c code, by returning
the state machine to the STOPPED state and returning the NACK
bit to the guest.
This bit of missing functionality was spotted by Coverity
(it noticed that we weren't checking the return value from
i2c_start_transfer()).
