- Include upstream patches designated as stable material and reviewed for applicability to include here. NOTE that the PIIX4 patch has migration implications: the change will also be applied to the SLE-15-SP2 qemu, and a live migration from that version to this SLE-15-SP3 qemu would require this patch to be applied for a successful migration if PIIX4 southbridge is used in the machine emulation (x86 i440fx) block-rbd-fix-memory-leak-in-qemu_rbd_co.patch block-rbd-Fix-memory-leak-in-qemu_rbd_co.patch cpu-core-Fix-help-of-CPU-core-device-typ.patch hw-arm-virt-acpi-build-Fix-GSIV-values-o.patch hw-block-fdc-Fix-fallback-property-on-sy.patch hw-isa-Kconfig-Add-missing-dependency-VI.patch hw-isa-piix4-Migrate-Reset-Control-Regis.patch hw-virtio-pci-Added-AER-capability.patch hw-virtio-pci-Added-counter-for-pcie-cap.patch s390x-css-report-errors-from-ccw_dstream.patch target-xtensa-fix-meson.build-rule-for-x.patch util-fix-use-after-free-in-module_load_o.patch virtio-pci-compat-page-aligned-ATS.patch OBS-URL: https://build.opensuse.org/request/show/885459 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=634

Subject: block/rbd: Fix memory leak in qemu_rbd_co_create_opts()
|
|
|
|
Git-commit: b084b420d9d6347dede328fbcf18c8e4c695f7e8
|
|
|
|
When we allocate 'q_namespace', we forgot to set 'has_q_namespace'
|
|
to true. This can cause several issues, including a memory leak,
|
|
since qapi_free_BlockdevCreateOptions() does not deallocate that
|
|
memory, as reported by valgrind:
|
|
|
|
13 bytes in 1 blocks are definitely lost in loss record 7 of 96

Fix setting 'has_q_namespace' to true when we allocate 'q_namespace'.
