2015-06-10virtio-net: enable virtio 1.0Cornelia Huck
virtio-net (non-vhost) now should have everything in place to support virtio 1.0: let's enable the feature bit for it. Note that VIRTIO_F_VERSION_1 is technically a transport feature; once every device is ready for virtio 1.0, we can move setting this feature bit out of the individual devices.

2015-06-10pcnet: force the buffer access to be in bounds during txPetr Matousek
4096 is the maximum length per TMD and it is also currently the size of the relay buffer pcnet driver uses for sending the packet data to QEMU for further processing. With packet spanning multiple TMDs it can happen that the overall packet size will be bigger than sizeof(buffer), which results in memory corruption. Fix this by only allowing to queue maximum sizeof(buffer) bytes. This is CVE-2015-3209.

2015-06-05q35: implement high SMRAMPaolo Bonzini
When H_SMRAME is 1, low memory at 0xa0000 is left alone by SMM, and instead the chipset maps the 0xa0000-0xbffff window at 0xfeda0000-0xfedbffff.

This region is exported at /machine/smram. It is "empty" if SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will enable/disable it as it enters or exits SMRAM. While touching nearby code, the existing memory region setup was slightly inconsistent. The smram_region is *disabled* in order to open SMRAM (because the smram_region shows the low VRAM instead of the RAM at 0xa0000). Because SMRAM is closed at startup, the smram_region must be enabled when creating the i440fx or q35 devices. Acked-by: Michael S.

2015-06-05framebuffer: check memory_region_is_loggingPaolo Bonzini
framebuffer.c expects DIRTY_MEMORY_VGA logging to be always on, but that will not be the case soon. Because framebuffer.c computes the memory region on the fly for every update (with memory_region_find), it cannot enable/disable logging by itself. Instead, always treat updates as invalidations if dirty logging is not enabled, assuming that the board will enable logging on the RAM region that includes the framebuffer.

2015-06-05memory: prepare for multiple bits in the dirty log maskPaolo Bonzini
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA, some listeners may be interested in the overall zero/non-zero value of the dirty log mask; others may be interested in the value of single bits. For this reason, always call log_start/log_stop if bits have respectively appeared or disappeared, and pass the old and new values of the dirty log mask so that listeners can distinguish the kinds of change. For example, KVM checks if dirty logging used to be completely disabled (in log_start) or is now completely disabled (in log_stop). On the other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed, since that is the only bit it cares about.

2015-06-05memory: differentiate memory_region_is_logging and ↵Paolo Bonzini
memory_region_get_dirty_log_mask For now memory regions only track DIRTY_MEMORY_VGA individually, but this will change soon. To support this, split memory_region_is_logging in two functions: one that returns a given bit from dirty_log_mask, and one that returns the entire mask. memory_region_is_logging gets an extra parameter so that the compiler flags misuse. While VGA-specific users (including the Xen listener!) will want to keep checking that bit, KVM and vhost check for "any bit except migration" (because migration is handled via the global start/stop listener callbacks).
