This patch adds to the vubr test the scattering of incoming
packets to the chain of RX buffer. Also, this patch corrects the
size of the header preceding the packet in RX buffers.
Note that this patch doesn't add the support for mergeable
buffers.

This fixes file descriptor leakage in vhost-user-bridge
application. Whenever a new callfd or kickfd is set, the previous
one should be explicitly closed. File descriptors used to map
guest's memory are closed immediately after mmap call.

During migration devices continue writing to the guest's memory.
The writes has to be reported to QEMU. This change implements
minimal support in vhost-user-bridge required for successful

This patch basically reverts commit d1f8b30e.

The test existing in QEMU for vhost-user feature is good for
testing the management protocol, but does not allow actual
traffic. This patch proposes Vhost-User Bridge application, which
can serve the QEMU community as a comprehensive test by running
real internet traffic by means of vhost-user interface.
Essentially the Vhost-User Bridge is a very basic vhost-user
backend for QEMU. It runs as a standalone user-level process.
For packet processing Vhost-User Bridge uses an additional QEMU
instance with a backend configured by "-net socket" as a shared
VLAN. This way another QEMU virtual machine can effectively
serve as a shared bus by means of UDP communication.
For a more simple setup, the another QEMU instance running the
SLiRP backend can be the same QEMU instance running vhost-user
client.
This Vhost-User Bridge implementation is very preliminary. It is
missing many features. I has been studying vhost-user protocol
internals, so I've written vhost-user-bridge bit by bit as I
progressed through the protocol. Most probably its internal
architecture will change significantly.
To run Vhost-User Bridge application:
1. Build vhost-user-bridge with a regular procedure. This will
create a vhost-user-bridge executable under tests directory:
$ configure; make tests/vhost-user-bridge
2. Ensure the machine has hugepages enabled in kernel with
command line like:
default_hugepagesz=2M hugepagesz=2M hugepages=2048
3. Run Vhost-User Bridge with:
$ tests/vhost-user-bridge
The above will run vhost-user server listening for connections
on UNIX domain socket /tmp/vubr.sock, and will try to connect
by UDP to VLAN bridge to localhost:5555, while listening on
localhost:4444
Run qemu with a virtio-net backed by vhost-user:
$ qemu \
-enable-kvm -m 512 -smp 2 \
-object memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on \
-numa node,memdev=mem -mem-prealloc \
-chardev socket,id=char0,path=/tmp/vubr.sock \
-netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,netdev=mynet1 \
-net none \
-net socket,vlan=0,udp=localhost:4444,localaddr=localhost:5555 \
-net user,vlan=0 \
disk.img
vhost-user-bridge was tested very lightly: it's able to bringup a
linux on client VM with the virtio-net driver, and execute transmits
and receives to the internet. I tested with "wget redhat.com",
"dig redhat.com".
PS. I've consulted DPDK's code for vhost-user during Vhost-User
Bridge implementation.
