The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).
We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.

The patch adds a flag to the qmp/hmp drive-backup command which enables

to enable this feature.
There are some limitations of the format driver to allow compressed writes.
We can write data only once. Though for backup this is perfectly fine.
These limitations are maintained by the driver and the error will be

This patch adds a way to specify multiple volfile servers to the gluster
block backend of QEMU with tcp|rdma transport types and their port numbers.
Problem:
Currently VM Image on gluster volume is specified like this:
file=gluster[+tcp]://host[:port]/testvol/a.img
Say we have three hosts in a trusted pool with replica 3 volume in action.
When the host mentioned in the command above goes down for some reason,
the other two hosts are still available. But there's currently no way
to tell QEMU about them.
Solution:
New way of specifying VM Image on gluster volume with volfile servers:
(We still support old syntax to maintain backward compatibility)
Basic command line syntax looks like:
Pattern I:
-drive driver=gluster,
volume=testvol,path=/path/a.raw,[debug=N,]
server.0.type=tcp,
server.0.host=1.2.3.4,
server.0.port=24007,
server.1.type=unix,
server.1.socket=/path/socketfile
Pattern II:
'json:{"driver":"qcow2","file":{"driver":"gluster",
"volume":"testvol","path":"/path/a.qcow2",["debug":N,]
"server":[{hostinfo_1}, ...{hostinfo_N}]}}'
driver => 'gluster' (protocol name)
volume => name of gluster volume where our VM image resides
path => absolute path of image in gluster volume
[debug] => libgfapi loglevel [(0 - 9) default 4 -> Error]
{hostinfo} => {{type:"tcp",host:"1.2.3.4"[,port=24007]},
{type:"unix",socket:"/path/sockfile"}}
type => transport type used to connect to gluster management daemon,
it can be tcp|unix
host => host address (hostname/ipv4/ipv6 addresses/socket path)
port => port number on which glusterd is listening.
socket => path to socket file
Examples:
1.
-drive driver=qcow2,file.driver=gluster,
file.volume=testvol,file.path=/path/a.qcow2,file.debug=9,
file.server.0.type=tcp,
file.server.0.host=1.2.3.4,
file.server.0.port=24007,
file.server.1.type=unix,
file.server.1.socket=/var/run/glusterd.socket
2.
'json:{"driver":"qcow2","file":{"driver":"gluster","volume":"testvol",
"path":"/path/a.qcow2","debug":9,"server":
[{"type":"tcp","host":"1.2.3.4","port":"24007"},
{"type":"unix","socket":"/var/run/glusterd.socket"}
]}}'
This patch gives a mechanism to provide all the server addresses, which are in
replica set, so in case host1 is down VM can still boot from any of the
active hosts.
This is equivalent to the backup-volfile-servers option supported by
mount.glusterfs (FUSE way of mounting gluster volume)

We want to eventually stick request_alignment alongside other
BlockLimits, but first, we must ensure it is populated at the
same time as all other limits, rather than being a special case
that is set only when a block is first opened.
Note that when the user does not provide "align", then we were
defaulting to bs->request_alignment - but at this stage in the
initialization, that was always 512. We were also rejecting an
explicit "align":0 from the user; this patch now allows that,
as an explicit request for the default alignment (which may not
always be 512 in the future).
qemu-iotests 77 is particularly sensitive to the fact that we
can specify an artificial alignment override in blkdebug, and
that override must continue to work even when limits are
refreshed on an already open device.

Add a block driver that is capable of supporting any full disk
encryption format. This utilizes the previously added block
encryption code, and at this time supports the LUKS format.
The driver code is capable of supporting any format supported
by the QCryptoBlock module, so it registers one block driver
for each format. This patch only registers the "luks" driver
since the "qcow" driver is there only for back-compatibility
with existing qcow built-in encryption.
New LUKS compatible volumes can be formatted using qemu-img
with defaults for all settings.
$ qemu-img create --object secret,data=123456,id=sec0 \
-f luks -o key-secret=sec0 demo.luks 10G
Alternatively the cryptographic settings can be explicitly
set
$ qemu-img create --object secret,data=123456,id=sec0 \
-f luks -o key-secret=sec0,cipher-alg=aes-256,\
cipher-mode=cbc,ivgen-alg=plain64,hash-alg=sha256 \
demo.luks 10G
And query its size
$ qemu-img info demo.img
image: demo.img
file format: luks
virtual size: 10G (10737418240 bytes)
disk size: 132K
encrypted: yes
Note that it was not necessary to provide the password
when querying info for the volume. The password is only
required when performing I/O on the volume
All volumes created by this new 'luks' driver should be
capable of being opened by the kernel dm-crypt driver.
The only algorithms listed in the LUKS spec that are
not currently supported by this impl are sha512 and
ripemd160 hashes and cast6 cipher.

Oddly enough, this change does not affect the resulting
