hw/virtio: fix crash in processing balloon stats
...
balloon_stats_get_all will iterate over guest stats upto the max
VIRTIO_BALLOON_S_NR value, calling visit_type_uint64 to populate
the QObject dict. The dict keys are obtained from the static
array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size.
Unfortunately the way that array is declared results in any
unassigned stats getting a NULL name, which will then cause
visit_type_uint64 to trigger an assert in qobject_output_add_obj.
The balloon_stat_names array was fortunately fully populated with
names until recently:
commit 0d2eeef77a
Author: Bibo Mao <maobibo@loongson.cn>
Date: Mon Oct 28 10:38:09 2024 +0800
linux-headers: Update to Linux v6.12-rc5
pulled a change to include/standard-headers/linux/virtio_balloon.h
which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new
names to balloon_stat_names.
This commit fills in the missing names, and uses a static assert to
guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause
a build failure until balloon_stat_names is updated.
This problem was detected by the Cockpit Project's automated
integration tests on QEMU 9.2.0-rc1.
