VMDK disk data is stored in extents, which may or may not be separate
from bs->file. VmdkExtent.file points to where they are stored. Each
that is stored in bs->file will simply reuse the exact pointer value of
bs->file.
(That is why vmdk_free_extents() will unref VmdkExtent.file (e->file)
only if e->file != bs->file.)
Reopen operations can change bs->file (they will replace the whole
BdrvChild object, not just the BDS stored in that BdrvChild), and then
we will need to change all .file pointers of all such VmdkExtents to
point to the new BdrvChild.
In vmdk_reopen_prepare(), we have to check which VmdkExtents are
affected, and in vmdk_reopen_commit(), we can modify them. We have to
split this because:
- The new BdrvChild is created only after prepare, so we can change
VmdkExtent.file only in commit
- In commit, there no longer is any (valid) reference to the old
BdrvChild object, so there would be nothing to compare VmdkExtent.file
against to see whether it was equal to bs->file before reopening
(There is BDRVReopenState.old_file_bs, but the old bs->file
BdrvChild's .bs pointer will be NULL-ed when the new BdrvChild is
created, and so we cannot compare VmdkExtent.file->bs against
BDRVReopenState.old_file_bs)

qcow2_co_invalidate_cache() closes and opens the qcow2 file, by calling
qcow2_close() and qcow2_do_open(). These two functions must thus be
usable from both a global-state and an I/O context.
As they are, they are not safe to call in an I/O context, because they
use bdrv_unref_child() and bdrv_open_child() to close/open the data_file
child, respectively, both of which are global-state functions. When
used from qcow2_co_invalidate_cache(), we do not need to close/open the
data_file child, though (we do not do this for bs->file or bs->backing
either), and so we should skip it in the qcow2_co_invalidate_cache()
path.
To do so, add a parameter to qcow2_do_open() and qcow2_close() to make
them skip handling s->data_file, and have qcow2_co_invalidate_cache()
exempt it from the memset() on the BDRVQcow2State.
(Note that the QED driver similarly closes/opens the QED image by
invoking bdrv_qed_close()+bdrv_qed_do_open(), but both functions seem
safe to use in an I/O context.)

The spec clarifies now that QEMU should not send a file descriptor in a
request to remove a memory region. Change it accordingly.
For libvhost-user, this is a bug fix that makes it compatible with
rust-vmm's implementation that doesn't send a file descriptor. Keep
accepting, but ignoring a file descriptor for compatibility with older
QEMU versions.

Outside of postcopy mode, neither VHOST_USER_ADD_MEM_REG nor
VHOST_USER_REM_MEM_REG are supposed to send a reply unless explicitly
requested with the need_reply flag. Their current implementation always
sends a reply, even if it isn't requested. This confuses the master
because it will interpret the reply as a reply for the next message for
which it actually expects a reply.
need_reply is already handled correctly by vu_dispatch(), so just don't
send a reply in the non-postcopy part of the message handler for these
two commands.

The specification for VHOST_USER_ADD/REM_MEM_REG messages is unclear
in several points, which has led to clients having incompatible
implementations. This changes the specification to be more explicit
about them:
* VHOST_USER_ADD_MEM_REG is not specified as receiving a file
descriptor, though it obviously does need to do so. All
implementations agree on this one, fix the specification.
* VHOST_USER_REM_MEM_REG is not specified as receiving a file
descriptor either, and it also has no reason to do so. rust-vmm does
not send file descriptors for removing a memory region (in agreement
with the specification), libvhost-user and QEMU do (which is a bug),
though libvhost-user doesn't actually make any use of it.
Change the specification so that for compatibility QEMU's behaviour
becomes legal, even if discouraged, but rust-vmm's behaviour becomes
the explicitly recommended mode of operation.
* VHOST_USER_ADD_MEM_REG doesn't have a documented return value, which
is the desired behaviour in the non-postcopy case. It also implemented
like this in QEMU and rust-vmm, though libvhost-user is buggy and
sometimes sends an unexpected reply. This will be fixed in a separate
patch.
However, in postcopy mode it does reply like VHOST_USER_SET_MEM_TABLE.
This behaviour is shared between libvhost-user and QEMU; rust-vmm
doesn't implement postcopy mode yet. Mention it explicitly in the
spec.
* The specification doesn't mention how VHOST_USER_REM_MEM_REG
identifies the memory region to be removed. Change it to describe the
existing behaviour of libvhost-user (guest address, user address and
size must match).

The qemu_*block() functions are meant to be be used with sockets (the
win32 implementation expects SOCKET)
Over time, those functions where used with Win32 SOCKET or
file-descriptors interchangeably. But for portability, they must only be
used with socket-like file-descriptors. FDs can use
g_unix_set_fd_nonblocking() instead.
Rename the functions with "socket" in the name to prevent bad usages.
This is effectively reverting commit f9e8cacc55 ("oslib-posix:

An expression in aspeed_gpio_set_pin_level was using a logical NOT

value &= !pin_mask;
The original author probably intended to make a bitwise NOT expression
"~", but mistakenly used a logical NOT operator "!" instead. Some
programming languages like Rust use "!" for both purposes.
