3db2bd5508c86a1605258bc77c9672d93b5c350e.
Since both ways of constructing the queue are now valid, this patch

block: Don't queue the same BDS twice in bdrv_reopen_queue_child()
bdrv_reopen_queue_child() assumes that a BlockDriverState is never
added twice to BlockReopenQueue.
That's however not the case: commit_start() adds 'base' (and its
children) to a new reopen queue, and then 'overlay_bs' (and its
children, which include 'base') to the same queue. The effect of this
is that the first set of options is ignored and overriden by the
second.
We fixed this by swapping the order in which both BDSs were added to
the queue in
3db2bd5508c86a1605258bc77c9672d93b5c350e. This patch
checks if a BDS is already in the reopen queue and keeps its options.

This adds the "read-only" option to the QDict. One important effect of

previously.
This addresses scenarios like this:

In this case, if we reopen [D] with read-only=off, and later reopen
[B], then [D] will not inherit read-only=on from its parent during the
bdrv_reopen_queue_child() stage.

block: Set BDRV_O_ALLOW_RDWR and snapshot_options before storing the flags
If an image is opened with snapshot=on, its flags are modified by
bdrv_backing_options() and then bs->open_flags is updated accordingly.
This last step is unnecessary if we calculate the new flags before
setting bs->open_flags.
Soon we'll introduce the "read-only" option, and then we'll need to
be able to modify its value in the QDict when snapshot=on. This is
more cumbersome if bs->options is already set. This patch simplifies
that. Other than that, there are no semantic changes. Although it
might seem that bs->options can have a different value now because
it is stored after calling bdrv_backing_options(), this call doesn't
actually modify them in this scenario.
The code that sets BDRV_O_ALLOW_RDWR is also moved for the same
reason.

qcow2: fix encryption during cow of sectors
Broken in previous commit:
commit
aaa4d20b4972bb1a811ce929502e6741835d584e
Author: Kevin Wolf <kwolf@redhat.com>
Date: Wed Jun 1 15:21:05 2016 +0200
qcow2: Make copy_sectors() byte based
The copy_sectors() code was originally using the 'sector'
parameter for encryption, which was passed in by the caller
from the QCowL2Meta.offset field (aka the guest logical
offset).
After the change, the code is using 'cluster_offset' which
was passed in from QCow2L2Meta.alloc_offset field (aka the
host physical offset).
This would cause the data to be encrypted using an incorrect
initialization vector which will in turn cause later reads
to return garbage.
Although current qcow2 built-in encryption is blocked from
usage in the emulator, one could still hit this if writing
to the file via qemu-{img,io,nbd} commands.

dma: xlnx-zynq-devcfg: Fix up XLNX_ZYNQ_DEVCFG_R_MAX
Whilst according to the Zynq TRM this device covers a register region of
0x000 - 0x120. The register region is also shared with XADCIF prefix
registers at 0x100 and above. Due to how the devcfg and the xadc devices
are implemented in QEMU these are separate models with individual mmio
regions. As such the region registered by the devcfg overlaps with the
xadc when initialized in a machine model (e.g. xilinx-zynq-a9).
This patch fixes up the incorrect region size, where
XLNX_ZYNQ_DEVCFG_R_MAX is missing its '/ 4' causing it to be 0x460 in
size. As well as setting the region size to the 0x0 - 0x100 region so
that an xadc device instance can be registered in the correct region to

which means we will not fail clone attempts which ask for features
that we can't implement. Add sanity checking of the flags to clone

linux-user: SIGSEGV from sigreturn need not be fatal
If the sigreturn syscall fails to read memory then this causes a
SIGSEGV, but this is not necessarily a fatal signal -- the guest
process can catch it.
We don't implement this correctly because the behaviour of QEMU's
force_sig() function has drifted away from the kernel function of the
same name -- ours now does "always do a guest core dump and abort
execution", whereas the kernel version simply forces the guest to
take a signal, which may or may not eventually cause a core dump.
Rename our force_sig() to dump_core_and_abort(), and provide a
force_sig() which acts more like the kernel version as the sigreturn
implementations expect it to. Since force_sig() now returns, we must
update all the callsites to return -TARGET_QEMU_ESIGRETURN so that
the main loop doesn't change the guest registers before the signal
handler is invoked.

down to a SHMLBA boundary

commit: get the overlay node before manipulating the backing chain
The 'block-commit' command has a 'top' parameter to specify the
topmost node from which the data is going to be copied.
[E] <- [D] <- [C] <- [B] <- [A]
In this case if [C] is the top node then this is the result:
[E] <- [B] <- [A]
[B] must be modified so its backing image string points to [E] instead
of [C]. commit_start() takes care of reopening [B] in read-write
mode, and commit_complete() puts it back in read-only mode once the
operation has finished.
In order to find [B] (the overlay node) we look for the node that has
[C] (the top node) as its backing image. However in commit_complete()
we're doing it after [C] has been removed from the chain, so [B] is
never found and remains in read-write mode.
This patch gets the overlay node before the backing chain is
manipulated.

blockdev: Add dynamic module loading for block drivers
Extend the current module interface to allow for block drivers to be
loaded dynamically on request. The only block drivers that can be
converted into modules are the drivers that don't perform any init
operation except for registering themselves.
In addition, only the protocol drivers are being modularized, as they
are the only ones which see significant performance benefits. The format
drivers do not generally link to external libraries, so modularizing
them is of no benefit from a performance perspective.
All the necessary module information is located in a new structure found
in module_block.h
This spoils the purpose of
5505e8b76f (block/dmg: make it modular).
Before this patch, if module build is enabled, block-dmg.so is linked to
libbz2, whereas the main binary is not. In downstream, theoretically, it
means only the qemu-block-extra package depends on libbz2, while the
main QEMU package needn't to. With this patch, we (temporarily) change
the case so that the main QEMU depends on libbz2 again.
