The data byte count(DBC) read from the description information is defined for
bits 21:00. Bits 30:22 are reserved and bit 31 is the Interrupt on Completion
(I) flag.
Completion interrupts are triggered after every transaction instead of on
I-flag in QEMU. tbl_entry_size is a signed integer and improperly reading the
DBC leads to a negative offset that causes sglist allocation to fail.

CVE-2013-4526
Within hw/ide/ahci.c, VARRAY refers to ports which is also loaded. So
we use the old version of ports to read the array but then allow any
value for ports. This can cause the code to overflow.
There's no reason to migrate ports - it never changes.
So just make sure it matches.

Non-PCI AHCI support is broken due to assertion failures when trying
to convert AHCIState to a PCIDevice pointer as AHCIState can have
different container structs. Fix this by using the non-asserting object
cast and checking the returned pointer is not NULL.
The AddressSpace pointer is also being initialized to NULL and causing
dma_memory_map call to fail. Fix this by initializing to
address_space_memory for sysbus instances.

[PMM: added linebreaks to fix overlong lines]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
When AHCI executes an asynchronous IDE command, it checked DRDY without
checking either DRQ or BSY. This sometimes caused interrupt to be sent
before command is actually completed.
This resulted in a race condition: if guest then managed to access the
device before command has completed, it would hang waiting for an
interrupt.
This was observed with windows 7 guests.
To fix, check for DRQ or BSY in additiona to DRDY, if set,
the command is asynchronous so delay the interrupt until
asynchronous done callback is invoked.

AHCI couldn't cope with asynchronous commands that aren't doing DMA, it
simply wouldn't complete them. Due to the bug fixed in commit f68ec837,
FLUSH commands would seem to have completed immediately even if they
were still running on the host. After the commit, they would simply hang
and never unset the BSY bit, rendering AHCI unusable on any OS sending
flushes.
This patch adds another callback for the completion of asynchronous
commands. This is what AHCI really wants to use for its command
completion logic rather than an DMA completion callback.

While testing q35, I found that windows 7 (specifically, windows 7 ultimate
with sp1 x64), wouldn't install because it can't find the cdrom or disk drive.
The failure message is: 'A required cd/dvd device driver is missing. If you
have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.'
This can also be reproduced on piix by adding an ahci controller, and
observing that windows 7 does not see any devices behind it.
The problem is that when windows issues a HBA reset, qemu does not reset the
individual ports' PxCMD register. Windows 7 then reads back the PxCMD register
and presumably assumes that the ahci controller has already been initialized.
Windows then never sets up the PxIE register to enable interrupts, and thus it
never gets irqs back when it sends ata device inquiry commands.
This change brings qemu into ahci 1.3 specification compliance.
Section 10.4.3 HBA Reset:
"
When GHC.HR is set to '1', GHC.AE, GHC.IE, the IS register, and all port
register fields (except PxFB/PxFBU/PxCLB/PxCLBU) that are not HwInit in the
HBA's register memory space are reset.
"

While testing q35, which has its cdrom attached to the ahci controller, I found
that the Fedora 17 install would panic on boot. The panic occurs while
squashfs is trying to read from the cdrom. The errors are:
[ 8.622711] SQUASHFS error: xz_dec_run error, data probably corrupt
[ 8.625180] SQUASHFS error: squashfs_read_data failed to read block
0x20be48a
I was also able to produce corrupt data reads using an installed piix based
qemu machine, using 'dd'. I found that the corruptions were only occuring when
then read size was greater than 128k. For example, the following command
results in corrupted reads:
dd if=/dev/sr0 of=/tmp/blah bs=256k iflag=direct
The > 128k size reads exercise a different code path than 128k and below. In
ide_atapi_cmd_read_dma_cb() s->io_buffer_size is capped at 128k. Thus,
ide_atapi_cmd_read_dma_cb() is called a second time when the read is > 128k.
However, ahci_dma_rw_buf() restart the read from offset 0, instead of at 128k.
Thus, resulting in a corrupted read.
To fix this, I've introduced 'io_buffer_offset' field in IDEState to keep
track of the offset. I've also modified ahci_populate_sglist() to take a new
3rd offset argument, so that the sglist is property initialized.
I've tested this patch using 'dd' testing, and Fedora 17 now correctly boots
and installs on q35 with the cdrom ahci controller.

dma-helpers.c contains a number of helper functions for doing

these directly access guest memory using cpu_physical_memory_*(),
assuming no IOMMU translation.
This patch updates this code to use the new universal DMA helper
functions. qemu_sglist_init() now takes a DMAContext * to describe
the DMA address space in which the scatter/gather will take place.
We minimally update the callers qemu_sglist_init() to pass NULL
(i.e. no translation, same as current behaviour). Some of those
callers should pass something else in some cases to allow proper IOMMU
translation in future, but that will be fixed in later patches.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in

The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,

Before commit 622b520f, index=12 meant bus=1,unit=5.
Since the commit, it means bus=0,unit=12. The drive is created, but
not the guest device. That's because the controllers we use with
if=scsi drives (lsi53c895a and esp) support only 7 units, and
scsi_bus_legacy_handle_cmdline() ignores drives with unit numbers
exceeding that limit.
Changing the mapping of index to bus, unit is a regression. Breaking
-drive invocations that used to work just makes it worse.
