2011-07-19scsi-disk: Mask out serial number EVPDHannes Reinecke
If the serial number is not set we should mask it out in the list of supported VPD pages and mark it as not supported. Signed-off-by: Hannes Reinecke <hare@suse.de> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-07-19scsi: Add 'hba_private' to SCSIRequestHannes Reinecke
'tag' is just an abstraction to identify the command from the driver. So we should make that explicit by replacing 'tag' with a driver-defined pointer 'hba_private'. This saves the lookup for driver handling several commands in parallel. 'tag' is still being kept for tracing purposes.

2011-07-18iov: Update parameter usage in iov_(to|from)_buf()Hannes Reinecke
iov_to_buf() has an 'offset' parameter, iov_from_buf() hasn't. This patch adds the missing parameter to iov_from_buf(). It also renames the 'offset' parameter to 'iov_off' to emphasize it's the offset into the iovec and not the buffer.

2011-07-12esp: cancel current request only if some request is in flightHervé Poussineau
This bug was introduced in 94d3f98a3f3caddd7875f9a11776daeb84962a7b: scsi_cancel_io was checking if some request was pending before trying to cancel it, while scsi_req_cancel always cancels the request. This may lead to a crash of Qemu due to dereferencing a NULL pointer, as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.

2011-07-05ide: Initialise buffers with zerosKevin Wolf
Just in case there's still a way how a guest can read out buffers when it's not supposed to, let's zero the buffers during initialisation so that we don't leak information to the guest. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
2011-07-05ide: Ignore reads during PIO in and writes during PIO outKevin Wolf
This fixes https://bugs.launchpad.net/qemu/+bug/786209: When the DRQ_STAT bit is set, the IDE core permits both data reads and data writes, regardless of whether the current transfer was initiated as a read or write. This potentially leaks uninitialized host memory into the guest, if, before doing anything else to an IDE device, the guest begins a write transaction (e.g. WIN_WRITE), but then *reads* from the IO port instead of writing to it.

2011-06-27virtio-serial: Fix segfault on guest bootLuiz Capitulino
If I start qemu with: # qemu -hda disks/test.img -enable-kvm -m 1G -snapshot \ -device virtio-serial \ -chardev socket,host=localhost,port=1234,server,nowait,id=foo \ -device virtserialport,chardev=foo,name=org.qemu.guest_agent I get a segfault when booting a Fedora 14 guest. The backtrace says: Program terminated with signal 11, Segmentation fault. #0 0x0000000000420850 in handle_control_message (vser=0x3732bd0, buf=0x2c173e0, len=8) at /home/lcapitulino/src/qmp-unstable/hw/virtio-serial-bus.c:335 335 info = DO_UPCAST(VirtIOSerialPortInfo, qdev, port->dev.info); What's happening is VIRTIO_CONSOLE_DEVICE_READY is a message for the whole device, not for an individual port. So port is NULL. This bug was introduced by commit a15bb0d6a981de749452a5180fc8084d625671da. This commit fixes that by making the port returned by find_port_by_id() be used only by the VIRTIO_CONSOLE_PORT_READY and VIRTIO_CONSOLE_PORT_OPEN messages.

2011-06-23usb: Add a speedmask to devicesHans de Goede
This is used to indicate at which speed[s] the device can operate, so that this can be checked to match the ports capabilities when it gets attached to a bus. Note that currently all usb1 emulated device claim to be fullspeed, this seems to not cause any problems, but still seems wrong, because with real hardware keyboards, mice and tablets usually are lo-speed, so reporting these as fullspeed devices seems wrong.

2011-06-23ehci: add freq + maxframes propertiesGerd Hoffmann
Add properties for the wakeup rate and the max number of frames ehci will process at once. The wakeup rate defaults to 1000 which equals the usb frame rate. This can be reduced to make qemu wake up less often when ehci is active. In case the wakeup rate is reduced or the ehci timer is delayed due to latency issues elsewhere in qemu ehci will process multiple frames at once. The maxframes property specifies the upper limit for this. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
