This is useful for other VSOCK transport implemented outside the
net/vmw_vsock/ directory to use these headers.

If we mod with VSOCK_HASH_SIZE -1, we get 0, 1, .... 249. Actually, we
have vsock_bind_table[0 ... 250] and vsock_connected_table[0 .. 250].
In this case the last entry will never be used.
We should mod with VSOCK_HASH_SIZE instead.

Most conflicts were minor overlapping stuff.
The be2net driver brought in some fixes that added __vlan_put_tag
calls, which in net-next take an additional argument.

If gcc (e.g. 4.1.2) decides not to inline vsock_init_tables(), this will
cause a section mismatch:
WARNING: net/vmw_vsock/vsock.o(.text+0x1bc): Section mismatch in reference from the function __vsock_core_init() to the function .init.text:vsock_init_tables()
The function __vsock_core_init() references
the function __init vsock_init_tables().
This is often because __vsock_core_init lacks a __init
annotation or the annotation of vsock_init_tables is wrong.
This may cause crashes if VSOCKETS=y and VMWARE_VMCI_VSOCKETS=m.

When we call vsock_core_init to init VSOCK the second time,
vsock_device.minor still points to the old dynamically allocated minor
number. misc_register will allocate it for us successfully as if we were
asking for a static one. However, when other user call misc_register to
allocate a dynamic minor number, it will give the one used by
vsock_core_init(), causing this:
[ 405.470687] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0xcc/0xf0()
[ 405.470689] Hardware name: OptiPlex 790
[ 405.470690] sysfs: cannot create duplicate filename '/dev/char/10:54'
Always set vsock_device.minor to MISC_DYNAMIC_MINOR before we
register.

The code misses to update the msg_namelen member to 0 and therefore
makes net/socket.c leak the local, uninitialized sockaddr_storage
variable to userland -- 128 bytes of kernel stack memory.

In case we received no data on the call to skb_recv_datagram(), i.e.
skb->data is NULL, vmci_transport_dgram_dequeue() will return with 0
without updating msg_namelen leading to net/socket.c leaking the local,
uninitialized sockaddr_storage variable to userland -- 128 bytes of
kernel stack memory.
Fix this by moving the already existing msg_namelen assignment a few
lines above.

The VMCI context ID of a virtual machine may change at any time. There
is a VMCI event which signals this but datagrams may be processed before
this is handled. It is therefore necessary to be flexible about the
destination context ID of any datagrams received. (It can be assumed to
be correct because it is provided by the hypervisor.) The context ID on
existing sockets should be updated to reflect how the hypervisor is
currently referring to the system.

The resource ID used for VM socket control packets (0) is already
used for the VMCI_GET_CONTEXT_ID hypercall so a new ID (15) must be
used when the guest sends these datagrams to the hypervisor.
The hypervisor context ID must also be removed from the internal
blacklist.

VM Sockets allows communication between virtual machines and the hypervisor.
User level applications both in a virtual machine and on the host can use the
VM Sockets API, which facilitates fast and efficient communication between
guest virtual machines and their host. A socket address family, designed to be
compatible with UDP and TCP at the interface level, is provided.
Today, VM Sockets is used by various VMware Tools components inside the guest
for zero-config, network-less access to VMware host services. In addition to
this, VMware's users are using VM Sockets for various applications, where
network access of the virtual machine is restricted or non-existent. Examples
of this are VMs communicating with device proxies for proprietary hardware
running as host applications and automated testing of applications running
within virtual machines.
The VMware VM Sockets are similar to other socket types, like Berkeley UNIX
socket interface. The VM Sockets module supports both connection-oriented
stream sockets like TCP, and connectionless datagram sockets like UDP. The VM
Sockets protocol family is defined as "AF_VSOCK" and the socket operations
split for SOCK_DGRAM and SOCK_STREAM.
For additional information about the use of VM Sockets, please refer to the
VM Sockets Programming Guide available at:
