beb5270034 fix I2C slave addressing
With the recent device handling changes the I2C slave addressing code
was broken. With current code, if a slave with the correct address is

not found on the bus the last scanned slave on the bus will be
addressed. This is wrong. Please find attached a patch to fix it.

3e01c7b93d net: disable draining tap queue in one go
If qemu_send_packet_async() returns zero, it means the packet has been
queued and the sent callback will be invoked once it has been flushed.

This is only possible where the NIC's receive() handler returns zero
and promises to notify the networking core that room is available in its
queue again.

In the case where the receive handler does not have this capability
(and its queue fills up) it returns -1 and the networking core does not
queue up the packet. This condition is indicated by a -1 return from
qemu_send_packet_async().

Currently, tap handles this condition simply by dropping the packet. It
should do its best to avoid getting into this situation by checking such
NIC's have room for a packet before copying the packet from the tap
interface.

tap_send() used to achieve this by only reading a single packet before
returning to the mainloop. That way, tap_can_send() is called before
reading each packet.

tap_send() was changed to completely drain the tap interface queue
without taking into account the situation where the NIC returns an
error and the packet is not queued. Let's start fixing this by
reverting to the previous behaviour of reading one packet at a time.

babd03fde6 usb-linux.c: fix buffer overflow
In usb-linux.c:usb_host_handle_control, we pass a 1024-byte buffer and
length to the kernel.  However, the length was provided by the caller
of dev->handle_packet, and is not checked, so the kernel might provide
too much data and overflow our buffer.

For example, hw/usb-uhci.c could set the length to 2047.
hw/usb-ohci.c looks like it might go up to 4096 or 8192.

This causes a qemu crash, as reported here:
  http://www.mail-archive.com/kvm@vger.kernel.org/msg18447.html

This patch increases the usb-linux.c buffer size to 2048 to fix the
specific device reported, and adds a check to avoid the overflow in
any case.

621cc70bfb RTC polling mode broken
The RTC emulation does not set the IRQ flags independent of the IRQ enable bits.

The original MC146818A datasheet from 1984 notes:
        "flag bits in Register C [...] are set independent of the
        state of the corresponding enable bits in Register B"
Similar sections can be found in newer documentation e.g. in rtc82885.

Qemu and Bochs set the IRQ flags only if they are enabled,
which breaks drivers polling on them.

The following patch corrects this for the update-ended-flag in Qemu only.
It does not fix the handling of the other flags.

ebeab049b0 qcow2: Order concurrent AIO requests on the same unallocated cluster
When two AIO requests write to the same cluster, and this cluster is
unallocated, currently both requests allocate a new cluster and the second one
merges the first one when it is completed. This means an cluster allocation, a
read and a cluster deallocation which cause some overhead. If we simply let the
second request wait until the first one is done, we improve overall performance
with AIO requests (specifially, qcow2/virtio combinations).

This patch maintains a list of in-flight requests that have allocated new
clusters. A second request touching the same cluster is limited so that it
either doesn't touch the allocation of the first request (so it can have a
non-overlapping allocation) or it waits for the first request to complete.

currently the vga screen_dump code doesn't use the DisplayState

52668cf7b3 sdl.c: support 32 bpp cursors
Hello,
currently when a 32 bpp cursor gets defined the result is all-black in
the areas that are not transparent (you'll get a 32 bpp cursor if you
use my previous patch to allow vmware_vga to use a 32 bpp framebuffer).
This is because the switch in sdl.c lacks a 32 bpp case.
The thing I am unsure about though is which byte is the unused one and
should be skipped, the first or the last - for the black-and-white
cursors I tested it doesn't make a difference...

for what I can tell, there is no way for vmware_vga to work correctly

with the current version of DisplaySurface.

b0f6d6c744 make windows notice media change
Windows seems to be very stupid about cdrom media change. It polls
cdrom status and if status goes ready->media not present->ready
it assumes that media was changed. If "media not present" step doesn't
happen even if "medium may have changed" was seen it assumes media
haven't changed. Fake "media not present" step.

Filip Navara did a great job debugging this issue in Windows and this is
what he found out:

BINGO! ... The media present notifications were broken ever since
Windows 2000 it seems. The media change is detected properly and it's
passed to ClassSetMediaChangeState function which in turn calls
ClasspInternalSetMediaChangeState. This function is responsible for
changing some internal state of the device object and sending the PnP
events which later result in application notifications. It has this
tiny bit of code (not copied byte for byte):

if (oldMediaState == NewState) {
  // Media is in the same state it was before.
  return;
}

so the end result is that for the case of UNIT NEEDS ATTENTION /
MEDIUM MAY HAVE CHANGED without NOT READY in-between is really broken.
It results in the internal media change counter incremented, so the
media contents are re-read when necessary, instead of relying on the
cache, but the notifications to applications are never sent.

cfd28938fc e1000.c doesn't properly emulate EERD and ICS registers
Once again, the emulation of the EERD and ICS registers in e1000.c is
incorrect. Nobody has noticed this before because none of the Intel-written
e1000 drivers use these registers, and all of the independently written open
source drivers copy Intel's example, so they don't use them either.
Regardless, these registers are documented in the programmer's manuals, and
their emulated behavior doesn't match the verified behavior of real hardware,
so any software that does use them doesn't function correctly.

9d61a50bdd Fix VM state change handlers running out of order
When a VM state change handler changes VM state, other VM state change
handlers can see the state transitions out of order.

bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state
change handlers to restart DMA.  These handlers can vm_stop() by
running into a write error on a drive with werror=stop.  This throws
the VM state change handler callback into disarray.  Here's an example
case I observed:

0. The virtual IDE drive goes south.  All future writes return errors.

1. Something encounters a write error, and duly stops the VM with
   vm_stop().

2. vm_stop() calls vm_state_notify(0).

3. vm_state_notify() runs the callbacks in list vm_change_state_head.
   It contains ide_dma_restart_cb() installed by bmdma_map().  It also
   contains audio_vm_change_state_handler() installed by audio_init().

4. audio_vm_change_state_handler() stops audio stuff.

5. User continues VM with monitor command "c".  This runs vm_start().

6. vm_start() calls vm_state_notify(1).

7. vm_state_notify() runs the callbacks in vm_change_state_head.

8. ide_dma_restart_cb() happens to come first.  It does its work, runs
   into a write error, and duly stops the VM with vm_stop().

9. vm_stop() runs vm_state_notify(0).

10. vm_state_notify() runs the callbacks in vm_change_state_head.

11. audio_vm_change_state_handler() stops audio stuff.  Which isn't
   running.

12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's
   vm_state_notify() resumes running handlers.

13. audio_vm_change_state_handler() starts audio stuff.  Oopsie.

Fix this by moving the actual write from each VM state change handler
into a new bottom half (suggested by Gleb Natapov).

96bc323100 target-mips: fix conditional moves off fp condition codes
Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code.  However,
get_fp_bit returns the bit number of the condition code, not a
bitmask.  (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)

Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

b87d79698d HPET fixes for reg writes
This patch addresses the problems found by Andriy Gapon:

- The code was incorrectly overwriting the high order 32
  bits of the timer and hpet config registers. This didn't show up
  in testing because linux and windows use hpet in legacy mode,
  where the high order 32 bits (advertising available interrupts)
  of the timer config register are ignored, and the high order 32
  bits of the hpet config register are reserved and unused.

- The mask for level-triggered interrupts was off by a bit. (hpet
  doesn't currently support level-triggered interrupts).

In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
windows use hpet in legacy mode where available interrupts are ignored.

QEMU Monitor Protocol
=====================
Introduction
-------------
The QEMU Monitor Protocol (QMP) allows applications to communicate with
QEMU's Monitor.
QMP is JSON[1] based and has the following features:
- Lightweight, text-based, easy to parse data format
- Asynchronous events support
- Stability
For more information, please, refer to the following files:
o qmp-spec.txt QEMU Monitor Protocol current specification
o qmp-commands.txt QMP supported commands
o qmp-events.txt List of available asynchronous events
There are also two simple Python scripts available:
o qmp-shell A shell
o vm-info Show some information about the Virtual Machine
[1] http://www.json.org
Usage
-----
To enable QMP, QEMU has to be started in "control mode". There are
two ways of doing this, the simplest one is using the the '-qmp'
command-line option.
For example:
$ qemu [...] -qmp tcp:localhost:4444,server
Will start QEMU in control mode, waiting for a client TCP connection
on localhost port 4444.
It is also possible to use the '-mon' command-line option to have
more complex combinations. Please, refer to the QEMU's manpage for
more information.
Simple Testing
--------------
To manually test QMP one can connect with telnet and issue commands:
$ telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

QEMU Monitor Protocol Specification - Version 0.1
1. Introduction
===============
This document specifies the QEMU Monitor Protocol (QMP), a JSON-based protocol
which is available for applications to control QEMU at the machine-level.
To enable QMP support, QEMU has to be run in "control mode". This is done by
starting QEMU with the appropriate command-line options. Please, refer to the
QEMU manual page for more information.
2. Protocol Specification
=========================
This section details the protocol format. For the purpose of this document
"Client" is any application which is communicating with QEMU in control mode,
and "Server" is QEMU itself.
JSON data structures, when mentioned in this document, are always in the
following format:
json-DATA-STRUCTURE-NAME
Where DATA-STRUCTURE-NAME is any valid JSON data structure, as defined by
the JSON standard:
http://www.ietf.org/rfc/rfc4627.txt
For convenience, json-object members and json-array elements mentioned in
this document will be in a certain order. However, in real protocol usage
they can be in ANY order, thus no particular order should be assumed.
2.1 General Definitions
-----------------------
2.1.1 All interactions transmitted by the Server are json-objects, always
terminating with CRLF
2.1.2 All json-objects members are mandatory when not specified otherwise
2.2 Server Greeting
-------------------
Right when connected the Server will issue a greeting message, which signals
that the connection has been successfully established and that the Server is
ready for capabilities negotiation (for more information refer to section
'4. Capabilities Negotiation').
The format is:
{ "QMP": { "version": json-object, "capabilities": json-array } }
Where,
- The "version" member contains the Server's version information (the format
is the same of the 'query-version' command)
- The "capabilities" member specify the availability of features beyond the
baseline specification
2.3 Issuing Commands
--------------------
The format for command execution is:
{ "execute": json-string, "arguments": json-object, "id": json-value }
Where,
- The "execute" member identifies the command to be executed by the Server
- The "arguments" member is used to pass any arguments required for the
execution of the command, it is optional when no arguments are required
- The "id" member is a transaction identification associated with the
command execution, it is optional and will be part of the response if
provided
2.4 Commands Responses
----------------------
There are two possible responses which the Server will issue as the result
of a command execution: success or error.
2.4.1 success
-------------
The success response is issued when the command execution has finished
without errors.
The format is:
{ "return": json-object, "id": json-value }
Where,
- The "return" member contains the command returned data, which is defined
in a per-command basis or an empty json-object if the command does not
return data
- The "id" member contains the transaction identification associated
with the command execution (if issued by the Client)
2.4.2 error
-----------
The error response is issued when the command execution could not be
completed because of an error condition.
The format is:
{ "error": { "class": json-string, "data": json-object, "desc": json-string },
"id": json-value }
Where,
- The "class" member contains the error class name (eg. "ServiceUnavailable")
- The "data" member contains specific error data and is defined in a
per-command basis, it will be an empty json-object if the error has no data
- The "desc" member is a human-readable error message. Clients should
not attempt to parse this message.
- The "id" member contains the transaction identification associated with
the command execution (if issued by the Client)
NOTE: Some errors can occur before the Server is able to read the "id" member,
in these cases the "id" member will not be part of the error response, even
if provided by the client.
2.5 Asynchronous events
-----------------------
As a result of state changes, the Server may send messages unilaterally
to the Client at any time. They are called 'asynchronous events'.
The format is:
{ "event": json-string, "data": json-object,
"timestamp": { "seconds": json-number, "microseconds": json-number } }
Where,
- The "event" member contains the event's name
- The "data" member contains event specific data, which is defined in a
per-event basis, it is optional
- The "timestamp" member contains the exact time of when the event occurred
in the Server. It is a fixed json-object with time in seconds and
microseconds
For a listing of supported asynchronous events, please, refer to the
qmp-events.txt file.
3. QMP Examples
===============
This section provides some examples of real QMP usage, in all of them
'C' stands for 'Client' and 'S' stands for 'Server'.
3.1 Server greeting
-------------------
S: {"QMP": {"version": {"qemu": "0.12.50", "package": ""}, "capabilities": []}}
3.2 Simple 'stop' execution
---------------------------
C: { "execute": "stop" }
S: {"return": {}}
3.3 KVM information
-------------------
C: { "execute": "query-kvm", "id": "example" }
S: {"return": {"enabled": true, "present": true}, "id": "example"}
3.4 Parsing error
------------------
C: { "execute": }
S: {"error": {"class": "JSONParsing", "desc": "Invalid JSON syntax", "data":
{}}}
3.5 Powerdown event
-------------------
S: {"timestamp": {"seconds": 1258551470, "microseconds": 802384}, "event":
"POWERDOWN"}
4. Capabilities Negotiation
----------------------------
When a Client successfully establishes a connection, the Server is in
Capabilities Negotiation mode.
In this mode only the 'qmp_capabilities' command is allowed to run, all
other commands will return the CommandNotFound error. Asynchronous messages
are not delivered either.
Clients should use the 'qmp_capabilities' command to enable capabilities
advertised in the Server's greeting (section '2.2 Server Greeting') they
support.
When the 'qmp_capabilities' command is issued, and if it does not return an
error, the Server enters in Command mode where capabilities changes take
effect, all commands (except 'qmp_capabilities') are allowed and asynchronous
messages are delivered.
5 Compatibility Considerations
------------------------------
All protocol changes or new features which modify the protocol format in an
incompatible way are disabled by default and will be advertised by the
capabilities array (section '2.2 Server Greeting'). Thus, Clients can check
that array and enable the capabilities they support.
Additionally, Clients must not assume any particular:
- Size of json-objects or length of json-arrays
- Order of json-object members or json-array elements
- Amount of errors generated by a command, that is, new errors can be added
to any existing command in newer versions of the Server
6. Downstream extension of QMP
------------------------------
We recommend that downstream consumers of QEMU do *not* modify QMP.
Management tools should be able to support both upstream and downstream
versions of QMP without special logic, and downstream extensions are
inherently at odds with that.
However, we recognize that it is sometimes impossible for downstreams to
avoid modifying QMP. Both upstream and downstream need to take care to
preserve long-term compatibility and interoperability.
To help with that, QMP reserves JSON object member names beginning with
'__' (double underscore) for downstream use ("downstream names"). This
means upstream will never use any downstream names for its commands,
arguments, errors, asynchronous events, and so forth.
Any new names downstream wishes to add must begin with '__'. To
ensure compatibility with other downstreams, it is strongly
recommended that you prefix your downstram names with '__RFQDN_' where
RFQDN is a valid, reverse fully qualified domain name which you
control. For example, a qemu-kvm specific monitor command would be:
(qemu) __org.linux-kvm_enable_irqchip
Downstream must not change the server greeting (section 2.2) other than
to offer additional capabilities. But see below for why even that is
discouraged.
Section '5 Compatibility Considerations' applies to downstream as well
as to upstream, obviously. It follows that downstream must behave
exactly like upstream for any input not containing members with
downstream names ("downstream members"), except it may add members
with downstream names to its output.
Thus, a client should not be able to distinguish downstream from
upstream as long as it doesn't send input with downstream members, and
properly ignores any downstream members in the output it receives.
Advice on downstream modifications:
1. Introducing new commands is okay. If you want to extend an existing
command, consider introducing a new one with the new behaviour
instead.
2. Introducing new asynchronous messages is okay. If you want to extend
an existing message, consider adding a new one instead.
3. Introducing new errors for use in new commands is okay. Adding new
errors to existing commands counts as extension, so 1. applies.
4. New capabilities are strongly discouraged. Capabilities are for
evolving the basic protocol, and multiple diverging basic protocol
dialects are most undesirable.

* An AsyncContext protects the callbacks of AIO requests and Bottom Halves

* synchronous bdrv_read/write that doesn't trigger any callbacks.
*
* However, these functions are often emulated using AIO which means that AIO
* callbacks must be run - but at the same time we must not run callbacks of
* other requests as they might start to modify metadata and corrupt the
* internal state of the caller of bdrv_read/write.
*
* To achieve the desired semantics we switch into a new AsyncContext.
* Callbacks must only be run if they belong to the current AsyncContext.
* Otherwise they need to be queued until their own context is active again.
* This is how you can make qemu_aio_wait() wait only for your own callbacks.

*
* Reference:
* http://forums.virtualbox.org/viewtopic.php?t=8046
*
* This driver supports create / read / write operations on VDI images.
*
* Todo (see also TODO in code):
*
* Some features like snapshots are still missing.
*
* Deallocation of zero-filled blocks and shrinking images are missing, too
* (might be added to common block layer).
*
* Allocation of blocks could be optimized (less writes to block map and
* header).
*
* Read and write of adjacents blocks could be done in one operation
* (current code uses one operation per block (1 MiB).
*
* The code is not thread safe (missing locks for changes in header and
* block table, no problem with current QEMU).
*
* Hints:
*
* Blocks (VDI documentation) correspond to clusters (QEMU).
* QEMU's backing files could be implemented using VDI snapshot files (TODO).
* VDI snapshot files may also contain the complete machine state.
* Maybe this machine state can be converted to QEMU PC machine snapshot data.
*
* The driver keeps a block cache (little endian entries) in memory.
* For the standard block size (1 MiB), a 1 TiB disk will use 4 MiB RAM,
* so this seems to be reasonable.
