2013-02-13s390: Fix handling of iscs.Cornelia Huck
There are two ways to express an interruption subclass: - As a bitmask, as used in cr6. - As a number, as used in the I/O interruption word. Unfortunately, we have treated to I/O interruption word as if it contained the bitmask as well, which went unnoticed so far as - (queued-for-next) kvm made the same mistake, and - Linux guest kernels don't check the isc value in the I/O interruption word for subchannel interrupts.

2013-02-13s390: Keep I/O interrupts enabled for all iscs.Cornelia Huck
do_io_interrupt() would stop scanning further iscs if it found an I/O interrupt it could inject.

2013-02-12block-migration: fix pending() and iterate() return valuesStefan Hajnoczi
The return value of .save_live_pending() is the number of bytes remaining. This is just an estimate because we do not know how many blocks will be dirtied by the running guest. Currently our return value for .save_live_pending() is wrong because it includes dirty blocks but not in-flight bdrv_aio_readv() requests or unsent blocks. Crucially, it also doesn't include the bulk phase where the entire device is transferred - therefore we risk completing block migration before all blocks have been transferred! The return value of .save_live_iterate() is the number of bytes transferred this iteration. Currently we return whether there are bytes remaining, which is incorrect. Move the bytes remaining calculation into .save_live_pending() and really return the number of bytes transferred this iteration in .save_live_iterate(). Also fix the %ld format specifier which was used for a uint64_t argument. PRIu64 must be use to avoid warnings on 32-bit hosts.

2013-02-12block/raw-posix: detect readonly Linux block devices using BLKROGETStefan Hajnoczi
Linux block devices can be set read-only with "blockdev --setro <device>". The same thing can be done for LVM volumes using "lvchange --permission r <volume>". This read-only setting is independent of device node permissions. Therefore the device can still be opened O_RDWR but actual writes will fail. This results in odd behavior for QEMU. bdrv_open() is supposed to fail if a read-only image is being opened with BDRV_O_RDWR. By not failing for Linux block devices, the guest boots up but every write produces an I/O error. This patch checks whether the block device is read-only so that Linux block devices behave like regular files.

2013-02-11migration: restrict scope of incoming fd read handlerStefan Hajnoczi
The incoming migration is processed in a coroutine and uses an fd read handler to enter the yielded coroutine when data becomes available. The read handler was set too broadly, so that spurious coroutine entries were be triggered if other coroutine users yielded (like the block layer's bdrv_write() function). Install the fd read only only when yielding for more data to become available. This prevents spurious coroutine entries which break code that assumes only a specific set of places can re-enter the coroutine. This patch fixes crashes in block/raw-posix.c that are triggered with "migrate -b" when qiov becomes a dangling pointer due to a spurious coroutine entry that frees qiov early.

2013-02-08hw/virtio-net.c: set config size using host featuresJesse Larrew
Currently, the config size for virtio devices is hard coded. When a new feature is added that changes the config size, drivers that assume a static config size will break. For purposes of backward compatibility, there needs to be a way to inform drivers of the config size needed to accommodate the set of features enabled. aliguori: merged in - hw/virtio-net: use existing macros to implement endof - hw/virtio-net: fix config_size data type Signed-off-by: Jesse Larrew <jlarrew@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
