2015-05-11qobject: Clean up around qtype_codeMarkus Armbruster
QTYPE_NONE is a sentinel value. No QObject has this type code. Document it properly. Fix dump_qobject() to abort() on QTYPE_NONE, just like for any other invalid type code. Fix to_json() to abort() on all invalid type codes, not just QTYPE_MAX. Clean up Property member qtype's type: it's a qtype_code.

2015-05-11QJSON: Use OBJECT_CHECKEduardo Habkost
The QJSON code used casts to (QJSON*) directly, instead of OBJECT_CHECK. There were even some functions using object_dynamic_cast() calls followed by assert(), which is exactly what OBJECT_CHECK does (by calling object_dynamic_cast_assert()).

2015-05-08qemu-nbd: only send a limited number of errno codes on the wirePaolo Bonzini
Right now, NBD includes potentially platform-specific error values in the wire protocol. Luckily, most common error values are more or less universal: in particular, of all errno values <= 34 (up to ERANGE), they are all the same on supported platforms except for 11 (which is EAGAIN on Windows and Linux, but EDEADLK on Darwin and the *BSDs). So, in order to guarantee some portability, only keep a handful of possible error codes and squash everything else to EINVAL. This patch defines a limited set of errno values that are valid for the NBD protocol, and specifies recommendations for what error to return in specific corner cases. The set of errno values is roughly based on the errors listed in the read(2) and write(2) man pages, with some exceptions: - ENOMEM is added for servers that implement copy-on-write or other formats that require dynamic allocation. - EDQUOT is not part of the universal set of errors; it can be changed to ENOSPC on the wire format. - EFBIG is part of the universal set of errors, but it is also changed to ENOSPC because it is pretty similar to ENOSPC or EDQUOT. Incoming values will in general match system errno values, but not on the Hurd which has different errno values (they have a "subsystem code" equal to 0x10 in bits 24-31). The Hurd is probably not something to which QEMU has been ported, but still do the right thing and reverse-map the NBD errno values to the system errno values. The corresponding patch to the NBD protocol description can be found at http://article.gmane.org/gmane.linux.drivers.nbd.general/3154. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-05-08rules.mak: Force CFLAGS for all objects in DSOFam Zheng
Because of the trick of process-archive-undefs, all .mo objects, even with --enable-modules, are dependencies of executables. This breaks CFLAGS propogation because the compiling of module object will happen too early before building for DSO. With GCC 5, the linking would fail because .o doesn't have -fPIC. Also, BUILD_DSO will be missed. (module-common.o will have it, so the stamp symbol was still liked in .so). Fix the problem by forcing the CFLAGS on individual .o-cflags during unnest-vars.

The dev->config pointer isn't set until guest system initializes usb devices (via usb_desc_set_config). However qemu networking can go through some motions prior to that, e.g.: #0 is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653 #1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315 #2 0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470 #3 0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101 #4 0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470 #5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172 The command to reproduce most reliably was: qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0 This wasn't strictly a problem with tap.

A new ioctl KVM_S390_IRQ is available which allows us to inject all local interrupts as defined in the Principles of Operation. It takes a struct kvm_s390_irq as a parameter which can store interrupt payload data for all interrupts. Let's use the new ioctl for injecting vcpu interrupts.

2015-05-08virtio-ccw: change realization sequenceCornelia Huck
virtio-ccw has an odd sequence of realizing devices: first the device-specific relization (net, block, ...), then the generic realization. It feels less odd to have the generic realization callback trigger the device-specific realization instead (and this also matches what virtio-pci does). One thing to note: We need to defer initializing the cu model in the sense id data until after the device-specific realization has been performed, as we need to refer to the virtio device's device_id.

2015-05-08s390-virtio: clear {used,avail}_event_idx on reset as wellChristian Borntraeger

2015-05-08s390-virtio: use common featuresCornelia Huck
We used to avoid enabling event_idx for virtio-blk devices via s390-virtio, but we now have a workaround in place for guests trying to use the device before setting DRIVER_OK. Therefore, let's add DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get those common features - and make s390-virtio use the same mechanism as the other transports do.

2015-05-08s390-virtio: Accommodate guests using virtqueues too earlyChristian Borntraeger
Feature updates are not a synchronuous operation for the legacy s390-virtio transport. This transport syncs the guest feature bits (those from finalize) on the set_status hypercall. Before that qemu thinks that features are zero, which means QEMU will misbehave, e.g. it will not write the event index, even if the guest asks for it. Let's detect the case where a kick happens before the driver is ready and force sync the features. With this workaround, it is now safe to switch to the common feature bit handling code as used by all other transports.
