CVE-2014-0077 [MEDIUM] vhost: fix total length when packets are too short
vhost: fix total length when packets are too short
When mergeable buffers are disabled, and the
incoming packet is too large for the rx buffer,
get_rx_bufs returns success.
This was intentional in order for make recvmsg
truncate the packet and then handle_rx would
detect err != sock_len and drop it.
Unfortunately we pass the original sock_len to
recvmsg - which means we use parts of iov not fully
validated.
Fix this up by detecting this overrun and doing packet drop
immediately.

A flaw was found in the way handle_rx() function handled big packets when mergeable buffers were disabled.
A privileged user in the guest could use this flaw to crash the host, or, potentially, escalate their privileges to the ones of the hosting qemu process by corrupting qemu memory.
