mmap(2) states:
'offset' must be a multiple of the page size as returned
by sysconf(_SC_PAGE_SIZE).
Add an assertion to be sure we don't break this contract.

The QEMU_VFIO_DEBUG definition is only modifiable at build-time.
Trace events can be enabled at run-time. As we prefer the latter,
convert qemu_vfio_dump_mappings() to use trace events instead
of fprintf().

We sometime get kernel panic with some devices on Aarch64
hosts. Alex Williamson suggests it might be broken PCIe
root complex. Add trace event to record the latest I/O
access before crashing. In case, assert our accesses are
aligned.

Currently, when using "nvme://" for a block device, like
-drive file=nvme://0000:01:00.0/1,if=none,id=drive0 \
-device virtio-blk,drive=drive0 \
VFIO may pin all guest memory, and discarding of RAM no longer works as
expected. I was able to reproduce this easily with my
01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
NVMe SSD Controller SM981/PM981/PM983
Similar to common VFIO, we have to disable it, making sure that:
a) virtio-balloon won't discard any memory ("silently disabled")
b) virtio-mem and nvme:// run mutually exclusive

pc,pci,vhost,virtio: fixes
Lots of fixes all over the place.
virtio-mem and virtio-iommu patches are kind of fixes but
it seems better to just make them behave sanely than
try to educate users about the limitations ...

Make it possible to compile out the vhost-user-blk server. It is enabled
by default on Linux.
Note that vhost-user-server.c depends on libvhost-user, which requires
CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that
option controls vhost-user frontends (previously known as "master") and
not device backends (previously known as "slave").

OptsVisitor, StringInputVisitor and the keyval visitor have
three different ideas of how a human could write the value of
a boolean option. Pay homage to the backwards-compatibility
gods and make the new common helper accept all four sets (on/off,
true/false, y/n and yes/no), but remove case-insensitivity.
Since OptsVisitor is supposed to match qemu-options, adjust
it as well.

Memory returned by get_relocated_path must be freed with
free or g_free depending on the path that the function
took; Coverity takes exception to this practice. The
fix lets caller use g_free as is standard in QEMU.
While at it, mention the requirements on the caller in
the doc comment.

The assert() was added in commit b681a1c73e15 ("block: Repair the
throttling code."), when the qemu_co_queue_do_restart() function
required to be running in a coroutine. It was later made unnecessary in
commit a9d9235567e7 ("coroutine-lock: reschedule coroutine on the
AioContext it was running on").

Commit 9ce44e2ce2 "qmp: Move dispatcher to a coroutine" modified
aio_poll() in util/aio-posix.c to avoid an assertion failure. This
change is missing in util/aio-win32.c.
Apply the changes to util/aio-posix.c to util/aio-win32.c too.
This fixes an assertion failure on Windows whenever QEMU exits.

The abstract socket namespace is a non-portable Linux extension. An
attempt to use it elsewhere should fail with ENOENT (the abstract
address looks like a "" pathname, which does not resolve). We report
this failure like
Failed to connect socket abc: No such file or directory
Tolerable, although ENOTSUP would be better.
However, introspection lies: it has @abstract regardless of host
support. Easy enough to fix: since Linux provides them since 2.2,
'if': 'defined(CONFIG_LINUX)' should do.
The above failure becomes
Parameter 'backend.data.addr.data.abstract' is unexpected
I consider this an improvement.

unix_listen_saddr() replaces empty @path by unique value. It obtains
the value by creating and deleting a unique temporary file with
mkstemp(). This is racy, as the comment explains. It's also entirely
undocumented as far as I can tell. Goes back to commit d247d25f18
"sockets: helper functions for qemu (Gerd Hoffman)", v0.10.0.
Since abstract socket addresses have no connection with filesystem
pathnames, making them up with mkstemp() seems inappropriate. Bypass
the replacement of empty @path.

Commit 776b97d360 "qemu-sockets: add abstract UNIX domain socket
support" neglected to update socket_sockaddr_to_address_unix(). The
function returns a non-abstract socket address for abstract
sockets (wrong) with a null @path (also wrong; a non-optional QAPI str
member must never be null).
The null @path is due to confused code going back all the way to
commit 17c55decec "sockets: add helpers for creating SocketAddress
from a socket".
Add the required special case, and simplify the confused code.

An optional bool member of a QAPI struct can be false, true, or absent.
The previous commit demonstrated that socket_listen() and
socket_connect() are broken for absent @tight, and indeed QMP chardev-
add also defaults absent member @tight to false instead of true.
In C, QAPI members are represented by two fields, has_MEMBER and MEMBER.
We have:
has_MEMBER MEMBER
false true false
true true true
absent false false/ignore
When has_MEMBER is false, MEMBER should be set to false on write, and
ignored on read.
For QMP, the QAPI visitors handle absent @tight by setting both
@has_tight and @tight to false. unix_listen_saddr() and
unix_connect_saddr() however use @tight only, disregarding @has_tight.
This is wrong and means that absent @tight defaults to false whereas it
should default to true.
The same is true for @has_abstract, though @abstract defaults to
false and therefore has the same behavior for all of QMP, HMP and CLI.
Fix unix_listen_saddr() and unix_connect_saddr() to check
@has_abstract/@has_tight, and to default absent @tight to true.
However, this is only half of the story. HMP chardev-add and CLI
-chardev so far correctly defaulted @tight to true, but defaults to
false again with the above fix for HMP and CLI. In fact, the "tight"
and "abstract" options now break completely.
Digging deeper, we find that qemu_chr_parse_socket() also ignores
@has_tight, leaving it false when it sets @tight. That is also wrong,
but the two wrongs cancelled out. Fix qemu_chr_parse_socket() to set
@has_tight and @has_abstract; writing testcases for HMP and CLI is left
for another day.

Reporting "Failed to connect socket" is essentially useless for a user
attempting to diagnose failure. It needs to include the target address
details. Similarly when failing to create a socket we should include the
socket family info, so the user understands what particular feature was
missing in their kernel build (IPv6, VSock in particular).

With upstream commit#ea1edcd7da1a "vl: relocate paths to data
directories", the data dir logic was unified between POSIX &
Win32. That patch moved to using 'get_relocated_path()', to
find the data dir. There is a latent bug in get_relocated_path
which can cause it to spin indefinitely, when the bind dir is
the same as the passed in dir (in this case, it was the data
dir).

Use the new QAPI block exports API instead of defining our own QOM
objects.
This is a large change because the lifecycle of VuBlockDev needs to
follow BlockExportDriver. QOM properties are replaced by QAPI options
objects.
VuBlockDev is renamed VuBlkExport and contains a BlockExport field.
Several fields can be dropped since BlockExport already has equivalents.
The file names and meson build integration will be adjusted in a future
patch. libvhost-user should probably be built as a static library that
is linked into QEMU instead of as a .c file that results in duplicate
compilation.
The new command-line syntax is:
$ qemu-storage-daemon \
--blockdev file,node-name=drive0,filename=test.img \
--export vhost-user-blk,node-name=drive0,id=export0,unix-socket=/tmp/vhost-user-blk.sock
Note that unix-socket is optional because we may wish to accept chardevs
too in the future.
Markus noted that supported address families are not explicit in the
QAPI schema. It is unlikely that support for more address families will
be added since file descriptor passing is required and few address
families support it. If a new address family needs to be added, then the
QAPI 'features' syntax can be used to advertize them.

This adds a special meaning for 'help' and '?' as options to the keyval
parser. Instead of being an error (because of a missing value) or a
value for an implied key, they now request help, which is a new boolean
output of the parser in addition to the QDict.
A new parameter 'p_help' is added to keyval_parse() that contains on
return whether help was requested. If NULL is passed, requesting help
results in an error and all other cases work like before.
Turning previous error cases into help is a compatible extension. The
behaviour potentially changes for implied keys: They could previously
get 'help' as their value, which is now interpreted as requesting help.
This is not a problem in practice because 'help' and '?' are not a valid
values for the implied key of any option parsed with keyval_parse():
* audiodev: union Audiodev, implied key "driver" is enum AudiodevDriver,
"help" and "?" are not among its values
* display: union DisplayOptions, implied key "type" is enum
DisplayType, "help" and "?" are not among its values
* blockdev: union BlockdevOptions, implied key "driver is enum
BlockdevDriver, "help" and "?" are not among its values
* export: union BlockExport, implied key "type" is enum BlockExportType,
"help" and "?" are not among its values
* monitor: struct MonitorOptions, implied key "mode" is enum MonitorMode,

The previous commit demonstrated documentation and code disagree on
parsing of ',' in the value of an implied key. Fix the code to match
the documentation.
This breaks uses of keyval_parse() that pass an implied key and accept
a value containing ','. None of the existing uses does:
* audiodev: implied key "driver" is enum AudiodevDriver, none of the
values contains ','
* display: implied key "type" is enum DisplayType, none of the values
contains ','
* blockdev: implied key "driver is enum BlockdevDriver, none of the
values contains ','
* export: implied key "type" is enum BlockExportType, none of the

* monitor: implied key "mode" is enum MonitorMode, none of the values
