2018-10-19clean up callback when del virtqueueliujunjie
Before, we did not clear callback like handle_output when delete the virtqueue which may result be segmentfault. The scene is as follows: 1. Start a vm with multiqueue vhost-net, 2. then we write VIRTIO_PCI_GUEST_FEATURES in PCI configuration to triger multiqueue disable in this vm which will delete the virtqueue. In this step, the tx_bh is deleted but the callback virtio_net_handle_tx_bh still exist. 3. Finally, we write VIRTIO_PCI_QUEUE_NOTIFY in PCI configuration to notify the deleted virtqueue. In this way, virtio_net_handle_tx_bh will be called and qemu will be crashed. Although the way described above is uncommon, we had better reinforce it.

2018-10-19savevm: split the process of different stages for loadvm/savevmZhang Chen
There are several stages during loadvm/savevm process. In different stage, migration incoming processes different types of sections. We want to control these stages more accuracy, it will benefit COLO performance, we don't have to save type of QEMU_VM_SECTION_START sections everytime while do checkpoint, besides, we want to separate the process of saving/loading memory and devices state. So we add three new helper functions: qemu_load_device_state() and qemu_savevm_live_state() to achieve different process during migration. Besides, we make qemu_loadvm_state_main() and qemu_save_device_state() public, and simplify the codes of qemu_save_device_state() by calling the wrapper qemu_savevm_state_header().

2018-10-19COLO: Flush memory data from ram cacheZhang Chen
During the time of VM's running, PVM may dirty some pages, we will transfer PVM's dirty pages to SVM and store them into SVM's RAM cache at next checkpoint time. So, the content of SVM's RAM cache will always be same with PVM's memory after checkpoint. Instead of flushing all content of PVM's RAM cache into SVM's MEMORY, we do this in a more efficient way: Only flush any page that dirtied by PVM since last checkpoint. In this way, we can ensure SVM's memory same with PVM's. Besides, we must ensure flush RAM cache before load device state.

2018-10-19COLO: Load dirty pages into SVM's RAM cache firstlyZhang Chen
We should not load PVM's state directly into SVM, because there maybe some errors happen when SVM is receving data, which will break SVM. We need to ensure receving all data before load the state into SVM. We use an extra memory to cache these data (PVM's ram). The ram cache in secondary side is initially the same as SVM/PVM's memory. And in the process of checkpoint, we cache the dirty pages of PVM into this ram cache firstly, so this ram cache always the same as PVM's memory at every checkpoint, then we flush this cached ram to SVM after we receive all PVM's state.

2018-10-19filter-rewriter: Add TCP state machine and fix memory leak in ↵Zhang Chen
connection_track_table We add almost full TCP state machine in filter-rewriter, except TCPS_LISTEN and some simplify in VM active close FIN states. The reason for this simplify job is because guest kernel will track the TCP status and wait 2MSL time too, if client resend the FIN packet, guest will resend the last ACK, so we needn't wait 2MSL time in filter-rewriter. After a net connection is closed, we didn't clear its related resources in connection_track_table, which will lead to memory leak. Let's track the state of net connection, if it is closed, its related resources will be cleared up.

2018-10-16tests: remove gcov-files- variablesPaolo Bonzini
Commit 31d2dda ("build-system: remove per-test GCOV reporting", 2018-06-20) removed users of the variables, since those uses can be replaced by a simple overall report produced by gcovr. However, the variables were never removed. Do it now.

2018-10-16tests: Prevent more accidental test disablingEric Blake
GNU make is perfectly happy to use 'check-FOO-y += bar' to initialize check-FOO-y. (GNU Automake strictly insists that you cannot use += until after an initial = per variable, but thankfully we aren't using automake). As we have had more than one instance where copy-and-paste of 'check-FOO-y = bar' from a first test under category FOO into an additional test, which ends up disabling the first (see commits 992159c7 and 4429532b), it's better to just always use the form that survives copy-and-paste, even for categories that don't currently add more than one test. Done with s/^\(check-[a-z]*-y \)=/\1+=/g Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2018-10-16target/cris/translate: Get rid of qemu_log_separate()Thomas Huth
The gen_BUG() function calls already cpu_abort(), which prints the information to stderr and the log already. So instead of additionally printing the dc->pc via fprintf() and qemu_log here, too, we can simply pass this information to cpu_abort() instead.
