Benoît Canet 12d3ba821d qmp: Allow to change password on named block driver states. 
Signed-off-by: Benoit Canet <benoit@irqsave.net>
Reviewed-by: Fam Zheng <famz@redhat.com>

There was two candidate ways to implement named node manipulation:

1)
{ 'command': 'block_passwd', 'data': {'*device': 'str',
                                      '*node-name': 'str', 'password': 'str'}
}

2)

{ 'command': 'block_passwd', 'data': {'device': 'str',
                                      '*device-is-node': 'bool',
                                      'password': 'str'} }

Luiz proposed 1 and says 2 was an abuse of the QMP interface and proposed to
rewrite the QMP block interface for 2.0.

Luiz does not like in 1 the fact that 2 fields are optional but one of them must
be specified leading to an abuse of the QMP semantic.

Kevin argumented that 2 what a clear abuse of the device field and would not be
practical when reading fast some log file because the user would read "device"
and think that a device is manipulated when it's in fact a node name.
Documentation of 1 make it pretty clear what to do for the user.

Kevin argued that all bs are node including devices ones so 2 does not make
sense.

Kevin also argued that rewriting the QMP block interface would not make disapear
the current one.

Kevin pushed the argument that making the QAPI generator compatible with the
semantic of the operation would need a rewrite that no one has done yet.

A vote has been done on the list to elect the version to use and 1 won.

For reference the complete thread is:
"[Qemu-devel] [PATCH V4 4/7] qmp: Allow to change password on names block driver
states."

# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.

# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.

# @dump-guest-memory
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take

# supported on i386 and x86_64.
#
# @paging: if true, do paging to get guest's memory mapping. This allows
# using gdb to process the core file.
#
# IMPORTANT: this option can make QEMU allocate several gigabytes
# of RAM. This can happen for a large guest, or a
# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:
#
# 1. The guest may be in a catastrophic state or can have corrupted
# memory, which cannot be trusted
# 2. The guest can be in real-mode even if paging is enabled. For
# example, the guest uses ACPI to sleep, and ACPI sleep state
# goes in real-mode
#
# @protocol: the filename or file descriptor of the vmcore. The supported
# protocols are:
#
# 1. file: the protocol starts with "file:", and the following
# string is the file's path.
# 2. fd: the protocol starts with "fd:", and the following string
# is the fd's name.
#
# @begin: #optional if specified, the starting physical address.
