[Qemu-devel] [PATCH v5 00/10] Fix device introspection regressions

[Markus Armbruster <armbru@redhat.com>]

QMP command device-list-properties regressed in 2.1: it can crash or
leave dangling pointers behind.

-device FOO,help regressed in 2.2: it no longer works for
non-pluggable devices.  I tried to fix that some time ago[*], but my
fix failed review.  This is my second, more comprehensive try.

PATCH 1-3 fixes one class of bugs involved in the regressions, PATCH
4-5 are libqtest preliminaries, PATCH 6 adds tests to demonstrate the
bugs, PATCH 7-9 fix them to a degree (see PATCH 8 for limitations),
and PATCH 10 cleans up.

v5:
* Prepend Paolo's "[PATCH 0/3] Fix dangling pointers from
  memory_region_init_*" series
* PATCH 2: Add fix for hw/pcmcia/pxa2xx.c
* PATCH 6: Document caller should g_free() return values [Thomas]
* PATCH 7: Drop devices fixed by Paolo from the blacklist
* PATCH 9: Rename cannot_even_create_with_object_new_yet to
  cannot_destroy_with_object_finalize_yet [Andreas],
  don't mark devices fixed by Paolo

v4:
* PATCH 4: Run "info qom-tree", refine blacklist, tweak commit
  message.
* PATCH 6: Mark "cgthree", "cuda", "integrator_debug", "macio",
  "pxa2xx-fir", "SUNW,tcx"; do not mark "spapr-rng" [Thomas]. tweak
  comments and commit message [Eduardo]

v3:
* PATCH 6: Mark "tilegx-cpu" [Eduardo] and new "spapr-rng", clean up
  whitespace

v2:
* PATCH 1: New, made from old PATCH 7 and relevant Makefile parts of
  old PATCH 3, with a much improved commit message [Andreas]
* PATCH 3: Fix hmp() [Eric]
* PATCH 4: Tweak commit message and comments [Eric]
* PATCH 6: Mark only the CPUs that are actually broken [Eduardo]

[*] [PATCH] qdev: Make -device FOO,help help again when FOO is not
pluggable
