From: Marc-André Lureau <marcandre.lur...@redhat.com> Hi,
Thanks to AddressSanitizer (ASAN), I found a number of direct leaks worth fixing. Note that there are probably many indirect leaks left (I am adding some here), I haven't investigated much yet. There are still a number of direct leaks remaining, in particular in the tests, but my libc doesn't give me good backtraces. In order to easily switch to asan-enabled build, I make use of make CFLAGS argument, which is why the first patch is also there. The series is also available for convenience in https://github.com/elmarco/qemu leak branch. v1->v2: - split "pci-bus: do not allocate and leak bsel" as a seperate patch, since the direct leak looks like a bug - hook virtio_input_finalize to the abstract base class - use mkdtemp in test-io-channel-command - fix pc-cpu-test commit message - move the sglist destruction inside of ncq_err, call dma_buf_commit in ide_dma_cb, as suggested by John Snow - fix build with glib 2.22 - add the given reviewed-by tags (22/37, 15 left) Marc-André Lureau (37): build-sys: use an override for CFLAGS filter tests: fix test-qga leaks qga: free the whole blacklist qga: free remaining leaking state tests: fix test-cutils leaks tests: fix test-vmstate leaks tests: fix test-iov leaks qdist: fix entries memory leak tests: fix check-qom-interface leaks tests: fix check-qom-proplist leaks tests: fix small leak in test-io-channel-command tests: fix leak in test-string-input-visitor portio: keep references on portio numa: do not leak NumaOptions pc: simplify passing qemu_irq pc: don't leak a20_line machine: use class base init generated name acpi-build: fix array leak char: disconnect peer when qemu_chr_free() char: free MuxDriver when closing tests: fix qom-test leaks pc: free i8259 pc: keep gsi reference ahci: free irqs array sd: free timer qjson: free str virtio-input: free config list ipmi: free extern timer usb: free USBDevice.strings tests: free a bunch of qmp responses usb: free leaking path bus: simplify name handling tests: add qtest_add_data_func_full tests: pc-cpu-test leaks fixes tests: fix rsp leak in postcopy-test ahci: fix sglist leak on retry tests: fix postcopy-test leaks hw/audio/gus.c | 9 ++++++--- hw/audio/sb16.c | 4 +++- hw/block/fdc.c | 4 +++- hw/char/parallel.c | 3 ++- hw/core/bus.c | 21 ++++++--------------- hw/core/machine.c | 1 + hw/display/vga-isa.c | 8 ++++++-- hw/dma/i8257.c | 6 ++++-- hw/i386/acpi-build.c | 4 ++-- hw/i386/pc.c | 9 +++++---- hw/i386/pc_piix.c | 17 ++++++++--------- hw/i386/pc_q35.c | 15 ++++++++------- hw/ide/ahci.c | 4 ++-- hw/ide/core.c | 7 +++++-- hw/input/pckbd.c | 4 ++-- hw/input/virtio-input.c | 11 +++++++++++ hw/ipmi/ipmi_bmc_extern.c | 9 +++++++++ hw/isa/isa-bus.c | 14 +++++--------- hw/sd/sd.c | 9 +++++++++ hw/usb/bus.c | 7 +++++++ hw/usb/desc.c | 1 + include/hw/boards.h | 2 +- include/hw/i386/pc.h | 4 ++-- include/hw/ide/internal.h | 2 ++ include/hw/isa/i8257.h | 2 ++ include/hw/isa/isa.h | 5 ++++- include/hw/qdev-core.h | 2 +- migration/qjson.c | 1 + numa.c | 15 ++++++++------- pc-bios/optionrom/Makefile | 4 ++-- qemu-char.c | 10 ++++++++++ qga/guest-agent-command-state.c | 7 +++++++ qga/guest-agent-core.h | 1 + qga/main.c | 14 ++++++++------ tests/check-qom-interface.c | 1 + tests/check-qom-proplist.c | 16 ++++++++++++++++ tests/libqos/usb.c | 1 + tests/libqtest.c | 15 ++++++++++++++- tests/libqtest.h | 7 ++++++- tests/pc-cpu-test.c | 24 +++++++++++++++++++----- tests/postcopy-test.c | 9 ++++++--- tests/pvpanic-test.c | 1 + tests/qom-test.c | 5 +++-- tests/test-cutils.c | 24 ++++++++++++++++-------- tests/test-filter-mirror.c | 4 +++- tests/test-filter-redirector.c | 8 ++++++-- tests/test-io-channel-command.c | 20 +++++++++++++------- tests/test-iov.c | 7 +++++++ tests/test-qga.c | 5 +++++ tests/test-string-input-visitor.c | 1 + tests/test-vmstate.c | 8 ++++++-- tests/virtio-blk-test.c | 19 +++++++++++++------ tests/virtio-net-test.c | 10 +++++++--- util/qdist.c | 3 ++- 54 files changed, 300 insertions(+), 124 deletions(-) -- 2.9.0
