qemu-dm buffer overrun in MSI-X handling

ISSUE DESCRIPTION "qemu-xen-traditional" aka qemu-dm tracks state for each MSI-X table entry of a passed through device. This is used/updated on intercepted accesses to the pages containing the MSI-X table. There may be space on the final page not covered by any MSI-X table entry, but memory for...

Long latency MMIO mapping operations are not preemptible

ISSUE DESCRIPTION The XENDOMCTLmemorymapping hypercall allows long running operations without implementing preemption. This hypercall is used by the device model as part of the emulation associated with configuration of PCI devices passed through to HVM guests and is therefore indirectly exposed ...
