2016-09-19qapi: check invalid arguments on no-args commandsMarc-André Lureau
The generated marshal functions do not visit arguments from commands that take no arguments. Thus they fail to catch invalid members. Visit the arguments, if provided, to throw an error in case of invalid members. Currently, qmp_check_client_args() checks for invalid arguments and correctly catches this case. When switching to qmp_dispatch() we want to keep that behaviour. The commands using 'O' may have arbitrary arguments, and must have 'gen': false in the qapi schema to skip the generated checks. Old/new diff: void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp) { Error *err = NULL; + Visitor *v = NULL; - (void)args; + if (args) { + v = qmp_input_visitor_new(QOBJECT(args), true); + visit_start_struct(v, NULL, NULL, 0, &err); + if (err) { + goto out; + } + + if (!err) { + visit_check_struct(v, &err); + } + visit_end_struct(v, NULL); + if (err) { + goto out; + } + } qmp_stop(&err); + +out: error_propagate(errp, err); + visit_free(v); + if (args) { + v = qapi_dealloc_visitor_new(); + visit_start_struct(v, NULL, NULL, 0, NULL); + + visit_end_struct(v, NULL); + visit_free(v); + } } The new code closely resembles code for a command with arguments. Differences: - the visit of the argument and its cleanup struct don't visit any members (because there are none). - the visit of the argument struct and its cleanup are conditional.

2016-09-19qmp: Hack to keep commands configuration-specificMarc-André Lureau
We currently define QMP commands in two places: the QAPI schema and qmp-commands.hx. The latter is preprocessed, the former is not. We use the preprocessor to suppress configuration-specific commands. For instance, query-spice is only available #ifdef CONFIG_SPICE. QMP command dispatch and query-commands use the qmp-commands.hx definition, and thus obey the #ifdeffery there. Good, because it lets QMP clients probe for available features more easily. query-qmp-schema uses the QAPI schema, and thus lists the configuration-specific commands even when they're unavailable. Not so good. We're about to flip command dispatch and query-commands to the non-middle-mode command registry, which uses the QAPI schema, so we can ditch qmp-commands.hx. To avoid regressing query-commands, arrange for commands that are suppressed with the preprocessor now to be unregistered with that registry. This will keep them unavailable and out of query-commands when we flip command dispatch and query-commands to that registry, exactly as before. This is a hack. The proper solution is to support configuration-specific commands in the QAPI schema. Mark it FIXME.

2016-09-16tcg: Merge GETPC and GETRARichard Henderson
The return address argument to the softmmu template helpers was confused. In the legacy case, we wanted to indicate that there is no return address, and so passed in NULL. However, we then immediately subtracted GETPC_ADJ from NULL, resulting in a non-zero value, indicating the presence of an (invalid) return address. Push the GETPC_ADJ subtraction down to the only point it's required: immediately before use within cpu_restore_state_from_tb, after all NULL pointer checks have been completed. This makes GETPC and GETRA identical. Remove GETRA as the lesser used macro, replacing all uses with GETPC. Signed-off-by: Richard Henderson <rth@twiddle.net>

2016-09-15vfio/pci: Fix regression in MSI routing configurationDavid Gibson
d1f6af6 "kvm-irqchip: simplify kvm_irqchip_add_msi_route" was a cleanup of kvmchip routing configuration, that was mostly intended for x86. However, it also contains a subtle change in behaviour which breaks EEH[1] error recovery on certain VFIO passthrough devices on spapr guests. So far it's only been seen on a BCM5719 NIC on a POWER8 server, but there may be other hardware with the same problem. It's also possible there could be circumstances where it causes a bug on x86 as well, though I don't know of any obvious candidates. Prior to d1f6af6, both vfio_msix_vector_do_use() and vfio_add_kvm_msi_virq() used msg == NULL as a special flag to mark this as the "dummy" vector used to make the host hardware state sync with the guest expected hardware state in terms of MSI configuration. Specifically that flag caused vfio_add_kvm_msi_virq() to become a no-op, meaning the dummy irq would always be delivered via qemu. d1f6af6 changed vfio_add_kvm_msi_virq() so it takes a vector number instead of the msg parameter, and determines the correct message itself. The test for !msg was removed, and not replaced with anything there or in the caller. With an spapr guest which has a VFIO device, if an EEH error occurs on the host hardware, then the device will be isolated then reset. This is a combination of host and guest action, mediated by some EEH related hypercalls. I haven't fully traced the mechanics, but somehow installing the kvm irqchip route for the dummy irq on the BCM5719 means that after EEH reset and recovery, at least some irqs are no longer delivered to the guest. In particular, the guest never gets the link up event, and so the NIC is effectively dead. [1] EEH (Enhanced Error Handling) is an IBM POWER server specific PCI-* error reporting and recovery mechanism. The concept is somewhat similar to PCI-E AER, but the details are different.

I would do the following instead, just in case we have extra code looking at $glib_subprocess one day.

2016-09-15curl: Operate on zero-length fileTomáš Golembiovský
Another attempt to fix the bug 1596870. When creating new disk backed by remote file accessed via HTTPS and the backing file has zero length, qemu-img terminates with uniformative error message: qemu-img: disk.qcow2: CURL: Error opening file: While it may not make much sense to operate on empty file, other block backends (e.g. raw backend for regular files) seem to allow it. This patch fixes it for the curl backend and improves the reported error. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
