Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

bdrv_truncate() is an operation that can block (even for a quite long time, depending on the PreallocMode) in I/O paths that shouldn't block. Convert it to a coroutine_fn so that we have the infrastructure for drivers to make their .bdrv_co_truncate implementation asynchronous. This change could potentially introduce new race conditions because bdrv_truncate() isn't necessarily executed atomically any more. Whether this is a problem needs to be evaluated for each block driver that supports truncate: * file-posix/win32, gluster, iscsi, nfs, rbd, ssh, sheepdog: The protocol drivers are trivially safe because they don't actually yield yet, so there is no change in behaviour. * copy-on-read, crypto, raw-format: Essentially just filter drivers that pass the request to a child node, no problem. * qcow2: The implementation modifies metadata, so it needs to hold s->lock to be safe with concurrent I/O requests. In order to avoid double locking, this requires pulling the locking out into preallocate_co() and using qcow2_write_caches() instead of bdrv_flush(). * qed: Does a single header update, this is fine without locking.

The previous commit fixed -blockdev breakage due to misuse of the qobject input visitor's keyval flavor in bdrv_file_open().

They are even marked FIXME.

Configuration flows through the block subsystem in a rather peculiar way. Configuration made with -drive enters it as QemuOpts. Configuration made with -blockdev / blockdev-add enters it as QAPI type BlockdevOptions. The block subsystem uses QDict, QemuOpts and QAPI types internally. The precise flow is next to impossible to explain (I tried for this commit message, but gave up after wasting several hours). What I can explain is a flaw in the BlockDriver interface that leads to this bug: $ qemu-system-x86_64 -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234 qemu-system-x86_64: -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234: Internal error: parameter user invalid QMP blockdev-add is broken the same way. Here's what happens. The block layer passes configuration represented as flat QDict (with dotted keys) to BlockDriver methods .bdrv_file_open(). The QDict's members are typed according to the QAPI schema. nfs_file_open() converts it to QAPI type BlockdevOptionsNfs, with qdict_crumple() and a qobject input visitor. This visitor comes in two flavors. The plain flavor requires scalars to be typed according to the QAPI schema. That's the case here. The keyval flavor requires string scalars. That's not the case here. nfs_file_open() uses the latter, and promptly falls apart for members @user, @group, @tcp-syn-count, @readahead-size, @page-cache-size, @debug. Switching to the plain flavor would fix -blockdev, but break -drive, because there the scalars arrive in nfs_file_open() as strings. The proper fix would be to replace the QDict by QAPI type BlockdevOptions in the BlockDriver interface. Sadly, that's beyond my reach right now. Next best would be to fix the block layer to always pass correctly typed QDicts to the BlockDriver methods. Also beyond my reach. What I can do is throw another hack onto the pile: have nfs_file_open() convert all members to string, so use of the keyval flavor actually works, by replacing qdict_crumple() by new function qdict_crumple_for_keyval_qiv(). The pattern "pass result of qdict_crumple() to qobject_input_visitor_new_keyval()" occurs several times more: * qemu_rbd_open() Same issue as nfs_file_open(), but since BlockdevOptionsRbd has only string members, its only a latent bug. Fix it anyway. * parallels_co_create_opts(), qcow_co_create_opts(), qcow2_co_create_opts(), bdrv_qed_co_create_opts(), sd_co_create_opts(), vhdx_co_create_opts(), vpc_co_create_opts() These work, because they create the QDict with qemu_opts_to_qdict_filtered(), which creates only string scalars. The function sports a TODO comment asking for better typing; that's going to be fun. Use qdict_crumple_for_keyval_qiv() to be safe.

There are numerous QDict functions that have been introduced for and are used only by the block layer. Move their declarations into an own header file to reflect that. While qdict_extract_subqdict() is in fact used outside of the block layer (in util/qemu-config.c), it is still a function related very closely to how the block layer works with nested QDicts, namely by sometimes flattening them. Therefore, its declaration is put into this header as well and util/qemu-config.c includes it with a comment stating exactly which function it needs.

We have too many driver callback interfaces; simplify the mess somewhat by merging the flags parameter of .bdrv_co_writev_flags() into .bdrv_co_writev(). Note that as long as a driver doesn't set .supported_write_flags, the flags argument will be 0 and behavior is identical. Also note that the public function bdrv_co_writev() still lacks a flags argument; so the driver signature is thus intentionally slightly different. But that's not the end of the world, nor the first time that the driver interface differs slightly from the public interface. Ideally, we should be rewriting all of these drivers to use modern byte-based interfaces. But that's a more invasive patch to write and audit, compared to the simplification done here.

The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *.

We would like to use a same QObject type to represent numbers, whether they are int, uint, or floats. Getters will allow some compatibility between the various types if the number fits other representations. Add a few more tests while at it.

SocketAddressLegacy is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. SocketAddress is the equivalent flat union. Convert all users of SocketAddressLegacy to SocketAddress, except for existing external interfaces. See also commit fce5d538..9445673e and 85a82e85..c5f1ae3a.

The next commit will rename SocketAddressFlat to SocketAddress, and the commit after that will replace most uses of SocketAddressLegacy by SocketAddress, replacing most of this commit's renames right back. Note that checkpatch emits a few "line over 80 characters" warnings. The long lines are all temporary; the SocketAddressLegacy replacement will shorten them again.
