The function get_fd extract context from the received MAD message and
uses it as a key to fetch the destination fd from the mapping table.
A context can be dgid in case of CM request message or comm_id in case
of CM SIDR response message.
When MAD message with a smaller size as expected for the message type
received we are hitting out-of-bounds where we are looking for the
context out of message boundaries.
Fix it by validating the message size.

Most list head structs need not be given a name. In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed. In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct. So clean up everything, not giving a
name except in the rare case where it is necessary.

RDMA MAD kernel module (ibcm) disallow more than one MAD-agent for a
given MAD class.
This does not go hand-by-hand with qemu pvrdma device's requirements
where each VM is MAD agent.
Fix it by adding implementation of RDMA MAD multiplexer service which on
one hand register as a sole MAD agent with the kernel module and on the
other hand gives service to more than one VM.
Design Overview:
Reviewed-by: Shamir Rabinovitch <shamir.rabinovitch@oracle.com>
----------------
A server process is registered to UMAD framework (for this to work the
rdma_cm kernel module needs to be unloaded) and creates a unix socket to
listen to incoming request from clients.
A client process (such as QEMU) connects to this unix socket and
registers with its own GID.
TX:
----
When client needs to send rdma_cm MAD message it construct it the same
way as without this multiplexer, i.e. creates a umad packet but this
time it writes its content to the socket instead of calling umad_send().
The server, upon receiving such a message fetch local_comm_id from it so
a context for this session can be maintain and relay the message to UMAD
layer by calling umad_send().
RX:
----
The server creates a worker thread to process incoming rdma_cm MAD
messages. When an incoming message arrived (umad_recv()) the server,
depending on the message type (attr_id) looks for target client by
either searching in gid->fd table or in local_comm_id->fd table. With
the extracted fd the server relays to incoming message to the client.

This is a QEMU specific version of a gitdm config for generating
reports on the contributor base of the project. I've added enough
group maps and domain aliases to ensure the current top ten is as
reflective as it can be. As of this commit running:

elf2dmp is a converter from ELF dump (produced by 'dump-guest-memory') to
Windows MEMORY.DMP format (also know as 'Complete Memory Dump') which can be
opened in WinDbg.
This tool can help if VMCoreInfo device/driver is absent in Windows VM and
'dump-guest-memory -w' is not available but dump can be created in ELF format.
The tool works as follows:
1. Determine the system paging root looking at GS_BASE or KERNEL_GS_BASE
to locate the PRCB structure and finds the kernel CR3 nearby if QEMU CPU
state CR3 is not suitable.
2. Find an address within the kernel image by dereferencing the first
IDT entry and scans virtual memory upwards until the start of the
kernel.
3. Download a PDB matching the kernel from the Microsoft symbol store,
and figure out the layout of certain relevant structures necessary for
the dump.
4. Populate the corresponding structures in the memory image and create
the appropriate dump header.

Read only feature shouldn't be negotiable, because if the
backend device reported Read only feature supported, QEMU
host driver shouldn't change backend's RO attribute. While
here, also enable the vhost-user-blk test utility to test
RO feature.
