2017-01-26aio-posix: honor is_external in AioContext pollingStefan Hajnoczi1-1/+2
AioHandlers marked ->is_external must be skipped when aio_node_check() fails. bdrv_drained_begin() needs this to prevent dataplane from submitting new I/O requests while another thread accesses the device and relies on it being quiesced. This patch fixes the following segfault: Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00005577f6127dad in bdrv_io_plug (bs=0x5577f7ae52f0) at qemu/block/io.c:2650 2650 bdrv_io_plug(child->bs); [Current thread is 1 (Thread 0x7ff5c4bd1c80 (LWP 10917))] (gdb) bt #0 0x00005577f6127dad in bdrv_io_plug (bs=0x5577f7ae52f0) at qemu/block/io.c:2650 #1 0x00005577f6114363 in blk_io_plug (blk=0x5577f7b8ba20) at qemu/block/block-backend.c:1561 #2 0x00005577f5d4091d in virtio_blk_handle_vq (s=0x5577f9ada030, vq=0x5577f9b3d2a0) at qemu/hw/block/virtio-blk.c:589 #3 0x00005577f5d4240d in virtio_blk_data_plane_handle_output (vdev=0x5577f9ada030, vq=0x5577f9b3d2a0) at qemu/hw/block/dataplane/virtio-blk.c:158 #4 0x00005577f5d88acd in virtio_queue_notify_aio_vq (vq=0x5577f9b3d2a0) at qemu/hw/virtio/virtio.c:1304 #5 0x00005577f5d8aaaf in virtio_queue_host_notifier_aio_poll (opaque=0x5577f9b3d308) at qemu/hw/virtio/virtio.c:2134 #6 0x00005577f60ca077 in run_poll_handlers_once (ctx=0x5577f79ddbb0) at qemu/aio-posix.c:493 #7 0x00005577f60ca268 in try_poll_mode (ctx=0x5577f79ddbb0, blocking=true) at qemu/aio-posix.c:569 #8 0x00005577f60ca331 in aio_poll (ctx=0x5577f79ddbb0, blocking=true) at qemu/aio-posix.c:601 #9 0x00005577f612722a in bdrv_flush (bs=0x5577f7c20970) at qemu/block/io.c:2403 #10 0x00005577f60c1b2d in bdrv_close (bs=0x5577f7c20970) at qemu/block.c:2322 #11 0x00005577f60c20e7 in bdrv_delete (bs=0x5577f7c20970) at qemu/block.c:2465 #12 0x00005577f60c3ecf in bdrv_unref (bs=0x5577f7c20970) at qemu/block.c:3425 #13 0x00005577f60bf951 in bdrv_root_unref_child (child=0x5577f7a2de70) at qemu/block.c:1361 #14 0x00005577f6112162 in blk_remove_bs (blk=0x5577f7b8ba20) at qemu/block/block-backend.c:491 #15 0x00005577f6111b1b in blk_remove_all_bs () at qemu/block/block-backend.c:245 #16 0x00005577f60c1db6 in bdrv_close_all () at qemu/block.c:2382 #17 0x00005577f5e60cca in main (argc=20, argv=0x7ffea6eb8398, envp=0x7ffea6eb8440) at qemu/vl.c:4684 The key thing is that bdrv_close() uses bdrv_drained_begin() and virtio_queue_host_notifier_aio_poll() must not be called.

2017-01-259pfs: fix offset error in v9fs_xattr_read()Greg Kurz1-3/+3
The current code tries to copy `read_count' bytes starting at offset `offset' from a `read_count`-sized iovec. This causes v9fs_pack() to fail with ENOBUFS. Since the PDU iovec is already partially filled with `offset' bytes, let's skip them when creating `qiov_full' and have v9fs_pack() to copy the whole of it. Moreover, this is consistent with the other places where v9fs_init_qiov_from_pdu() is called. This fixes commit "bcb8998fac16 9pfs: call v9fs_init_qiov_from_pdu before v9fs_pack".

2017-01-259pfs: fix off-by-one error in PDU free listGreg Kurz1-1/+1
The server can handle MAX_REQ - 1 PDUs at a time and the virtio-9p device has a MAX_REQ sized virtqueue. If the client manages to fill up the virtqueue, pdu_alloc() will fail and the request won't be processed without any notice to the client (it actually causes the linux 9p client to hang). This has been there since the beginning (commit 9f10751365b2 "virtio-9p: Add a virtio 9p device to qemu"), but it needs an agressive workload to run in the guest to show up. We actually allocate MAX_REQ PDUs and I see no reason not to link them all into the free list, so let's fix the init loop.

2017-01-24gdbstub.c: fix GDB connection segfault caused by empty machinesZiyue Yang1-0/+7
This patch is to fix the segmentation fault caused by attaching GDB to a QEMU instance initialized with "-M none" option. The bug can be reproduced by > ./qemu-system-x86_64 -M none -nographic -S -s and attach a GDB to it by > gdb -ex 'target remote :1234 The segmentation fault was originally caused by trying to read the information about CPU when communicating with GDB. However, it's impossible for any control flow to exist on an empty machine, nor can CPU's be hot plugged to an empty machine later by QOM commands. So I think simply disabling GDB connections on empty machines makes sense.

(See also related bug https://bugzilla.gnome.org/show_bug.cgi?id=764415) It is desirable to use the glib version instead of qemu copy, since it provides more debugging facilities (G_MAIN_POLL_DEBUG etc), and hopefully has a better maintainance.

2017-01-24migration/tracing: Add tracing on saveDr. David Alan Gilbert2-5/+14
Add some tracing to vmstate_subsection_save and vmstate_save_state to help in debugging when you're not sure if a conditional piece of data is being saved. In vmstate_subsection_save I renamed the inner vmsd to avoid the aliasing and be able to print both names.

2017-01-24PCI/migration merge vmstate_pci_device and vmstate_pcie_deviceDr. David Alan Gilbert10-41/+26
The vmstate_pci_device and vmstate_pcie_devices differ just in the size of one buffer; combine the two using a _TEST macro. I think this is safe as long as everywhere which currently uses either of these two uses the right type. One thing that concerns me is that some places use pci_device_load/save which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE macro - how are they getting the same irq mangling? This passes a smoke test migrate of: ./x86_64-softmmu/qemu-system-x86_64 -M pc,accel=kvm -m 1024 ./littlefed20.img -device e1000e -device virtio-net -device e1000 -device virtio-rng -device megasas -device megasas-gen2 -device ioh3420 -device nec-usb-xhci to an unmodified qemu.
