2013-03-08virtio-serial: make flow control explicit in virtio-consoleAmit Shah
virtio-console.c used to return a value less than the number of bytes asked to be written out to a chardev backend in case the backend is not writable. virtio-serial-bus.c then implicitly enabled flow control for that port.

2013-03-07hw/nand.c: correct the sense of the BUSY/READY status bitKuo-Jung Su
The BIT6 of Status Register(SR): SR[6] behaves the same as R/B# pin SR[6] = 0 indicates the device is busy; SR[6] = 1 means the device is ready Some NAND flash controller (i.e. ftnandc021) relies on the SR[6] to determine if the NAND flash erase/program is success or error timeout.

2013-03-05scsi-disk: handle io_canceled uniformly and correctlyPaolo Bonzini
Always check it immediately after calling bdrv_acct_done, and always do a "goto done" in case the "done" label has to free some memory---as is the case for scsi_unmap_complete in the previous patch. This patch could fix problems that happen when a request is split into multiple parts, and one of them is canceled. Then the next part is fired, but the HBA's cancellation callbacks have fired already. Whether this happens or not, depends on how the block/ driver implements AIO cancellation. It it does a simple bdrv_drain_all() or similar, then it will not have a problem. If it only cancels the given AIOCB, this scenario could happen.

2013-03-05iscsi: look for pkg-config file tooPaolo Bonzini
Due to library conflicts, Fedora will have to put libiscsi in /usr/lib/iscsi. Simplify configuration by using a pkg-config file.

2013-03-05iscsi: add iscsi_truncate supportPeter Lieven
this patch adds iscsi_truncate which effectively allows for online resizing of iscsi volumes. for this to work you have to resize the volume on your storage and then call block_resize command in qemu which will issue a readcapacity16 to update the capacity. v4: - factor out complete readcapacity logic into a separate function - handle capacity change check condition in readcapacity function (this happens if the block_resize cmd is the first iscsi task executed after a resize on the storage) v3: - remove switch statement in iscsi_open - create separate patch for brdv_drain_all() in bdrv_truncate() v2: - add a general bdrv_drain_all() before bdrv_truncate() to avoid in-flight AIOs while the device is truncated - since no AIOs are in flight we can use a sync libiscsi call to re-read the capacity - factor out the readcapacity16 logic as it is redundant to iscsi_open() and iscsi_truncate(). Signed-off-by: Peter Lieven <pl@kamp.de> [allow any type of unit attention check condition in iscsi_readcapacity_sync(), as in Message-ID: <51263A2A.6070304@dlhnet.de> - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-03-05iscsi: retry read, write, flush and unmap on unit attention check conditionsPeter Lieven
the storage might return a check condition status for various reasons.
