When developing the next version of "[PATCH 00/16] memory: Stop piggybacking on memory region owners*", I faced multiple memory region leaks and use-after-finalization. This series extracts their fixes so that the number of Cc: won't explode.
Patch "qdev: Automatically delete memory subregions" and the succeeding patches are for refactoring, but patch "vfio-user: Do not delete the subregion" does fix use-after-finalization. * https://lore.kernel.org/qemu-devel/20250901-mr-v1-0-dd7cb6b14...@rsg.ci.i.u-tokyo.ac.jp/ Signed-off-by: Akihiko Odaki <od...@rsg.ci.i.u-tokyo.ac.jp> --- Akihiko Odaki (22): docs/devel: Do not unparent in instance_finalize() vfio/pci: Do not unparent in instance_finalize() hw/pci-bridge: Do not assume immediate MemoryRegion finalization target/mips: Fix AddressSpace exposure timing target/xtensa: Fix AddressSpace exposure timing auxbus: Fix AddressSpace exposure timing hw/pci-host/raven: Fix AddressSpace exposure timing sun4m: Fix AddressSpace exposure timing sun4u: Fix AddressSpace exposure timing qdev: Automatically delete memory subregions vfio-user: Do not delete the subregion hw/char/diva-gsp: Do not delete the subregion hw/char/serial-pci-multi: Do not delete the subregion secondary-vga: Do not delete the subregions cmd646: Do not delete the subregions hw/ide/piix: Do not delete the subregions hw/ide/via: Do not delete the subregions hw/nvme: Do not delete the subregion pci: Do not delete the subregions hw/ppc/spapr_pci: Do not delete the subregions hw/usb/hcd-ehci: Do not delete the subregions hw/usb/hcd-xhci: Do not delete the subregions MAINTAINERS | 1 + docs/devel/memory.rst | 19 +++------ include/hw/pci/pci.h | 1 + include/hw/qdev-core.h | 1 + hw/char/diva-gsp.c | 1 - hw/char/serial-pci-multi.c | 1 - hw/core/qdev.c | 14 +++++++ hw/display/vga-pci.c | 8 ---- hw/ide/cmd646.c | 12 ------ hw/ide/piix.c | 13 ------- hw/ide/via.c | 12 ------ hw/misc/auxbus.c | 2 +- hw/nvme/ctrl.c | 2 - hw/pci-host/raven.c | 27 ++++++------- hw/pci/pci.c | 22 +---------- hw/pci/pci_bridge.c | 96 +++++++++++++++++++++++++--------------------- hw/ppc/spapr_pci.c | 22 ----------- hw/sparc/sun4m_iommu.c | 9 ++++- hw/sparc64/sun4u_iommu.c | 9 ++++- hw/usb/hcd-ehci.c | 4 -- hw/usb/hcd-xhci.c | 10 ----- hw/vfio-user/pci.c | 6 --- hw/vfio/pci.c | 4 -- stubs/memory.c | 9 +++++ target/mips/cpu.c | 9 ++++- target/xtensa/cpu.c | 8 ++-- stubs/meson.build | 1 + 27 files changed, 129 insertions(+), 194 deletions(-) --- base-commit: e101d33792530093fa0b0a6e5f43e4d8cfe4581e change-id: 20250906-use-37ecc903a9e0 Best regards, -- Akihiko Odaki <od...@rsg.ci.i.u-tokyo.ac.jp>
