+Subject: [PATCH] virtio-net: correctly drop truncated packets
+
+When packet is truncated during receiving, we drop the packets but
+neither discard the descriptor nor add and signal used
+descriptor. This will lead several issues:
+
+- sg mappings are leaked
+- rx will be stalled if a lots of packets were truncated
+
+In order to be consistent with vhost, fix by discarding the descriptor
+in this case.

+ size(CVE-2015-7504)
+
+In loopback mode, pcnet_receive routine appends CRC code to the
+receive buffer. If the data size given is same as the buffer size,
+the appended CRC code overwrites 4 bytes after s->buffer. Added a
+check to avoid that.

+Subject: [PATCH] ide: ahci: reset ncq object to unused on error
+
+When processing NCQ commands, AHCI device emulation prepares a
+NCQ transfer object; To which an aio control block(aiocb) object
+is assigned in 'execute_ncq_command'. In case, when the NCQ
+command is invalid, the 'aiocb' object is not assigned, and NCQ
+transfer object is left as 'used'. This leads to a use after
+free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
+Reset NCQ transfer object to 'unused' to avoid it.

+
+When IDE AHCI emulation uses Frame Information Structures(FIS)
+engine for data transfer, the mapped FIS buffer address is stored
+in a static 'bounce.buffer'. When a request is made to map another
+memory region, address_space_map() returns NULL because
+'bounce.buffer' is in_use. It leads to a null pointer dereference
+error while doing 'dma_memory_unmap'. Add a check to avoid it.

+USB Ehci emulation supports host controller capability registers.
+But its mmio '.write' function was missing, which lead to a null
+pointer dereference issue. Add a do nothing 'ehci_caps_write'
+definition to avoid it; Do nothing because capability registers
+are Read Only(RO).
