Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20200221-1' into staging (2020-02-21 16:18:38 +0000) are available in the Git repository at: https://github.com/stefanha/qemu.git tags/block-pull-request for you to fetch changes up to e5c59355ae9f724777c61c859292ec9db2c8c2ab: fuzz: add documentation to docs/devel/ (2020-02-22 08:26:48 +0000) ---------------------------------------------------------------- Pull request This pull request contains a virtio-blk/scsi performance optimization, event loop scalability improvements, and a qtest-based device fuzzing framework. I am including the fuzzing patches because I have reviewed them and Thomas Huth is currently away on leave. ---------------------------------------------------------------- Alexander Bulekov (22): softmmu: move vl.c to softmmu/ softmmu: split off vl.c:main() into main.c module: check module wasn't already initialized fuzz: add FUZZ_TARGET module type qtest: add qtest_server_send abstraction libqtest: add a layer of abstraction to send/recv libqtest: make bufwrite rely on the TransportOps qtest: add in-process incoming command handler libqos: rename i2c_send and i2c_recv libqos: split qos-test and libqos makefile vars libqos: move useful qos-test funcs to qos_external fuzz: add fuzzer skeleton exec: keep ram block across fork when using qtest main: keep rcu_atfork callback enabled for qtest fuzz: support for fork-based fuzzing. fuzz: add support for qos-assisted fuzz targets fuzz: add target/fuzz makefile rules fuzz: add configure flag --enable-fuzzing fuzz: add i440fx fuzz targets fuzz: add virtio-net fuzz target fuzz: add virtio-scsi fuzz target fuzz: add documentation to docs/devel/ Denis Plotnikov (1): virtio: increase virtqueue size for virtio-scsi and virtio-blk Paolo Bonzini (1): rcu_queue: add QSLIST functions Stefan Hajnoczi (7): aio-posix: avoid reacquiring rcu_read_lock() when polling util/async: make bh_aio_poll() O(1) aio-posix: fix use after leaving scope in aio_poll() aio-posix: don't pass ns timeout to epoll_wait() qemu/queue.h: add QLIST_SAFE_REMOVE() aio-posix: make AioHandler deletion O(1) aio-posix: make AioHandler dispatch O(1) with epoll MAINTAINERS | 11 +- Makefile | 15 +- Makefile.objs | 2 - Makefile.target | 19 ++- block.c | 5 +- chardev/spice.c | 4 +- configure | 39 +++++ docs/devel/fuzzing.txt | 116 ++++++++++++++ exec.c | 12 +- hw/block/virtio-blk.c | 2 +- hw/core/machine.c | 2 + hw/scsi/virtio-scsi.c | 2 +- include/block/aio.h | 26 ++- include/qemu/module.h | 4 +- include/qemu/queue.h | 32 +++- include/qemu/rcu_queue.h | 47 ++++++ include/sysemu/qtest.h | 4 + include/sysemu/sysemu.h | 4 + qtest.c | 31 +++- scripts/checkpatch.pl | 2 +- scripts/get_maintainer.pl | 3 +- softmmu/Makefile.objs | 3 + softmmu/main.c | 53 +++++++ vl.c => softmmu/vl.c | 48 +++--- tests/Makefile.include | 2 + tests/qtest/Makefile.include | 72 +++++---- tests/qtest/fuzz/Makefile.include | 18 +++ tests/qtest/fuzz/fork_fuzz.c | 55 +++++++ tests/qtest/fuzz/fork_fuzz.h | 23 +++ tests/qtest/fuzz/fork_fuzz.ld | 37 +++++ tests/qtest/fuzz/fuzz.c | 179 +++++++++++++++++++++ tests/qtest/fuzz/fuzz.h | 95 +++++++++++ tests/qtest/fuzz/i440fx_fuzz.c | 193 ++++++++++++++++++++++ tests/qtest/fuzz/qos_fuzz.c | 234 +++++++++++++++++++++++++++ tests/qtest/fuzz/qos_fuzz.h | 33 ++++ tests/qtest/fuzz/virtio_net_fuzz.c | 198 +++++++++++++++++++++++ tests/qtest/fuzz/virtio_scsi_fuzz.c | 213 +++++++++++++++++++++++++ tests/qtest/libqos/i2c.c | 10 +- tests/qtest/libqos/i2c.h | 4 +- tests/qtest/libqos/qos_external.c | 168 ++++++++++++++++++++ tests/qtest/libqos/qos_external.h | 28 ++++ tests/qtest/libqtest.c | 119 ++++++++++++-- tests/qtest/libqtest.h | 4 + tests/qtest/pca9552-test.c | 10 +- tests/qtest/qos-test.c | 132 +--------------- tests/test-aio.c | 3 +- tests/test-rcu-list.c | 16 ++ tests/test-rcu-slist.c | 2 + util/aio-posix.c | 187 +++++++++++++++------- util/async.c | 237 ++++++++++++++++------------ util/module.c | 7 + 51 files changed, 2365 insertions(+), 400 deletions(-) create mode 100644 docs/devel/fuzzing.txt create mode 100644 softmmu/Makefile.objs create mode 100644 softmmu/main.c rename vl.c => softmmu/vl.c (99%) create mode 100644 tests/qtest/fuzz/Makefile.include create mode 100644 tests/qtest/fuzz/fork_fuzz.c create mode 100644 tests/qtest/fuzz/fork_fuzz.h create mode 100644 tests/qtest/fuzz/fork_fuzz.ld create mode 100644 tests/qtest/fuzz/fuzz.c create mode 100644 tests/qtest/fuzz/fuzz.h create mode 100644 tests/qtest/fuzz/i440fx_fuzz.c create mode 100644 tests/qtest/fuzz/qos_fuzz.c create mode 100644 tests/qtest/fuzz/qos_fuzz.h create mode 100644 tests/qtest/fuzz/virtio_net_fuzz.c create mode 100644 tests/qtest/fuzz/virtio_scsi_fuzz.c create mode 100644 tests/qtest/libqos/qos_external.c create mode 100644 tests/qtest/libqos/qos_external.h create mode 100644 tests/test-rcu-slist.c -- 2.24.1
