[PATCH v2 00/12] Fixes for 11.1

Posted by Marc-André Lureau 2 months ago

Hi

Here are some assorted patches worth considering for the 11.1 freeze
bug-fix period.

Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>
---
Changes in v2, after Akihiko comments:
- split the "Fix many -Werror=maybe-uninitialized" patch
- qdev-monitor: add drain_rcu parameter to avoid deadlock from virtio-net
- rewrite WITH_QEMU_LOCK_GUARD/WITH_RCU_READ_LOCK_GUARD macros to suppress
  GCC false-positive warnings (new patch)
- block/blkio: use QEMU_LOCK_GUARD instead of WITH_QEMU_LOCK_GUARD in
  getlength() to avoid false-positive (new patch)
- hw/cxl: split invalid-free fix into its own patch
- hw/i3c: fix default return value of d2_i3c_send() (new patch)
- hw/ppc: fix dangling machine->fdt reference after spapr fdt updates (new patch)
- Link to v1: https://lore.kernel.org/qemu-devel/20260725-fix2-v1-0-5c9a6ce7b96a@redhat.com
