Previously copy-on-read could only be enabled for all requests to a block device. This means requests coming from the guest as well as QEMU's internal requests would perform copy-on-read when enabled. For image streaming we want to support finer-grained behavior than just populating the image file from its backing image. Image streaming supports partial streaming where a common backing image is preserved. In this case guest requests should not perform copy-on-read because they would indiscriminately copy data which should be left in a backing image from the backing chain. Introduce a per-request flag for copy-on-read so that a block device can process both regular and copy-on-read requests. Overlapping reads and writes still need to be serialized for correctness when copy-on-read is happening, so add an in-flight reference count to track this.

Long-running block operations like block migration and image streaming must have continual access to their block device. It is not safe to perform operations like hotplug, eject, change, resize, commit, or external snapshot while a long-running operation is in progress. This patch adds the missing bdrv_in_use() checks so that block migration and image streaming never have the rug pulled out from underneath them.

Currently on the pseries machine the SLOF firmware is used normally, but we bypass it when -kernel is specified. Having these two different boot paths can cause some confusion. In particular at present we need to "probe" the (emulated) PCI bus and produce device tree nodes for the PCI devices in qemu, for the -kernel case. In the SLOF case, it takes the device tree from qemu adds some stuff to it then passes it on to the kernel. It's been decided that a better approach is to always boot through SLOF, even when using -kernel. WIth this approach we can leave PCI probing and device node creation to SLOF in all cases which removes a bunch of code in qemu, and avoids iterating the PCI devices from the machine specific init code which we're not supposed to do. This patch changes qemu to always boot through SLOF, and not to create PCI nodes. Simultaneously it updates the included version of SLOF (submodule and binary image) to one which supports (and requires) the new approach. The new SLOF version also includes a number of unrelated enhancements: support for booting from virtio-pci devices and e1000, greatly improved FCode support and many bugfixes. It also makes SLOF ready to be used even when specifying a kernel on the qemu command line.

The pseries machine expects a para-virtualized guest and so supplies RTAS functions (via a hypercall) for performing PCI config space access. Currently the implementation of these calls into pci_default_{read,write}_config(). However this would be incorrect for any PCI device which overrides the default config read/write functions. AFAICT there's only one such device today, but we should still get it right. In addition the pci_host_config_{read,write}_common() functions which do correctly do this dispatch, perform bounds checking on the config space address, lack of which currently leads to an exploitable bug. This patch corrects the problem. Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NAlexander Graf <agraf@suse.de>

The kvm_get_dirty_pages_log_range() function uses two address variables to step through the monitored memory region to update the dirty log. However, these variables have type unsigned long, which can overflow if running a 64-bit guest with a 32-bit qemu binary.

When accessing the device specific virtio config space, we memcpy the data into a variable in QEMU. At that point we're basically pulling host endianness into the game which is a really bad idea. So instead, let's use the target specific load/store helpers for memory pointers which fetch things in target endianness. The whole array is already populated in target endianness anyways (see virtio-blk). Signed-off-by: NAlexander Graf <agraf@suse.de> Reviewed-by: NAnthony Liguori <aliguori@us.ibm.com>

The virtio config area in PIO space is a bit special. The initial header is little endian but the rest (device specific) is guest native endian. The PIO accessors for PCI on machines that don't have native IO ports assume that all PIO is little endian, which works fine for everything except the above. A complicated way to fix it would be to split the BAR into two memory regions with different endianess settings, but this isn't practical to do, besides, the PIO code doesn't honor region endianness anyway (I have a patch for that too but it isn't necessary at this stage). So I decided to go for the quick fix instead which consists of reverting the swap in virtio-pci in selected places, hoping that when we eventually do a "v2" of the virtio protocols, we sort that out once and for all using a fixed endian setting for everything.
