2020-12-19qobject: Change qobject_to_json()'s value to GStringMarkus Armbruster1-15/+7
qobject_to_json() and qobject_to_json_pretty() build a GString, then covert it to QString. Just one of the callers actually needs a QString: qemu_rbd_parse_filename(). A few others need a string they can modify: qmp_send_response(), qga's send_response(), to_json_str(), and qmp_fd_vsend_fds(). The remainder just need a string. Change qobject_to_json() and qobject_to_json_pretty() to return the GString. qemu_rbd_parse_filename() now has to convert to QString. All others save a QString temporary. to_json_str() actually becomes a bit simpler, because GString provides more convenient modification functions.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake4-71/+21
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-11-16qga: update schema for guest-get-disks 'dependents' fieldMichael Roth2-8/+10
The recently-added 'guest-get-disk' command returns a list of GuestDiskInfo entries, which in turn have a 'dependents' field which lists devices these entries are dependent upon. Thus, 'dependencies' is a better name for this field. Address this by renaming the field accordingly. Additionally, 'dependents' is specified as non-optional, even though it's not implemented for w32. This is misleading, since it gives users the impression that a particular disk might not have dependencies, when in reality that information is simply not known to the guest agent. Address this by making 'dependents' an optional field, and only marking it as in-use when the facilities to obtain this information are available to the guest agent.

2020-11-02qga-win: Fix guest-get-devices error API violationsMarkus Armbruster1-3/+2
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. qmp_guest_get_devices() is wrong that way: it calls error_setg() in a loop. If no iteration fails, the function returns a value and sets no error. Okay. If exactly one iteration fails, the function returns a value and sets an error. Wrong. If multiple iterations fail, the function trips error_setv()'s assertion. Fix it to return immediately on error. Perhaps the failure to convert the driver version to UTF-8 should not be an error. We could simply not report the botched version string instead. Drop a superfluous continue while there.

2020-11-02qga: Rename guest-get-devices return member 'address' to 'id'Markus Armbruster2-16/+17
Member 'address' is union GuestDeviceAddress with a single branch GuestDeviceAddressPCI, containing PCI vendor ID and device ID. This is not a PCI address. Type GuestPCIAddress is. Messed up in recent commit 2e4211cee4 "qga: add command guest-get-devices for reporting VirtIO devices". Rename type GuestDeviceAddressPCI to GuestDeviceIdPCI, type GuestDeviceAddress to GuestDeviceId, and member 'address' to 'id'. Document the member properly while there.

Add some section headings to the QGA json; this is purely so that we have some H1 headings, as otherwise each command ends up being visible in the interop/ manual's table of contents.

2020-09-29docs/interop: Convert qemu-ga-ref to rSTPeter Maydell1-2/+1
Convert qemu-ga-ref to rST format. This includes dropping the plain-text, pdf and info format outputs for this document; as with all our other Sphinx-based documentation, we provide HTML and manpage only. The qemu-ga-ref.rst is somewhat more stripped down than the .texi was, because we do not (currently) attempt to generate indexes for the commands, events and data types being documented. As the GA ref is now part of the Sphinx 'interop' manual, we can delete the direct link from index.html.in.

2020-09-23qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi1-6/+6
clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

Add command for reporting devices on Windows guest. The intent is not so much to report the devices but more importantly the driver (and its version) that is assigned to the device. This gives caller the information whether VirtIO drivers are installed and/or whether inadequate driver is used on a device (e.g. QXL device with base VGA driver). Example: [ { "driver-date": "2019-08-12", "driver-name": "Red Hat VirtIO SCSI controller", "driver-version": "100.80.104.17300", "address": { "type": "pci", "data": { "device-id": 4162, "vendor-id": 6900 } } }, ... ] Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> *remove redundant glib autoptr declaration for GuestDeviceInfo Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
