2017-07-10qemu-img: drop -e and -6 options from the 'create' & 'convert' commandsDaniel P. Berrange
The '-e' and '-6' options to the 'create' & 'convert' commands were "deprecated" in favour of the more generic '-o' option many years ago: commit eec77d9e712bd4157a4e1c0b5a9249d168add738 Author: Jes Sorensen <Jes.Sorensen@redhat.com> Date: Tue Dec 7 17:44:34 2010 +0100 qemu-img: Deprecate obsolete -6 and -e options Except this was never actually a deprecation, which would imply giving the user a warning while the functionality continues to work for a number of releases before eventual removal. Instead the options were immediately turned into an error + exit. Given that the functionality is already broken, there's no point in keeping these psuedo-deprecation messages around any longer.

2017-07-10block: Guarantee that *file is set on bdrv_get_block_status()Eric Blake
We document that *file is valid if the return is not an error and includes BDRV_BLOCK_OFFSET_VALID, but forgot to obey this contract when a driver (such as blkdebug) lacks a callback. Messed up in commit 67a0fd2 (v2.6), when we added the file parameter. Enhance qemu-iotest 177 to cover this, using a sequence that would print garbage or even SEGV, because it was dererefencing through uninitialized memory. [The resulting test output shows that we have less-than-ideal block status from the blkdebug driver, but that's a separate fix coming up soon.] Setting *file on all paths that return BDRV_BLOCK_OFFSET_VALID is enough to fix the crash, but we can go one step further: always setting *file, even on error, means that a broken caller that blindly dereferences file without checking for error is now more likely to get a reliable SEGV instead of randomly acting on garbage, making it easier to diagnose such buggy callers. Adding an assertion that file is set where expected doesn't hurt either.

2017-07-10qemu-io: Don't die on second openEric Blake
Most callback commands in qemu-io return 0 to keep the interpreter loop running, or 1 to quit immediately. However, open_f() just passed through the return value of openfile(), which has different semantics of returning 0 if a file was opened, or 1 on any failure. As a result of mixing the return semantics, we are forcing the qemu-io interpreter to exit early on any failures, which is rather annoying when some of the failures are obviously trying to give the user a hint of how to proceed (if we didn't then kill qemu-io out from under the user's feet): $ qemu-io qemu-io> open foo qemu-io> open foo file open already, try 'help close' $ echo $? 0 In general, we WANT openfile() to report failures, since it is the function used in the form 'qemu-io -c "$something" no_such_file' for performing one or more -c options on a single file, and it is not worth attempting $something if the file itself cannot be opened. So the solution is to fix open_f() to always return 0 (when we are in interactive mode, even failure to open should not end the session), and save the return value of openfile() for command line use in main(). Note, however, that we do have some qemu-iotests that do 'qemu-io -c "open file" -c "$something"'; such tests will now proceed to attempt $something whether or not the open succeeded, the same way as if the two commands had been attempted in interactive mode. As such, the expected output for those tests has to be modified. But it also means that it is now possible to use -c close and have a single qemu-io command line operate on more than one file even without using interactive mode. Although the '-c open' action is a subtle change in behavior, remember that qemu-io is for debugging purposes, so as long as it serves the needs of qemu-iotests while still being reasonable for interactive use, it should not be a problem that we are changing tests to the new behavior. This has been awkward since at least as far back as commit e3aff4f, in 2009.

2017-07-05virtio-scsi-ccw: use ioeventfd even when KVM is disabledQingFeng Hao
This patch is based on a similar patch from Stefan Hajnoczi - commit c324fd0a39c ("virtio-pci: use ioeventfd even when KVM is disabled") Do not check kvm_eventfds_enabled() when KVM is disabled since it always returns 0. Since commit 8c56c1a592b5092d91da8d8943c17777d6462a6f ("memory: emulate ioeventfd") it has been possible to use ioeventfds in qtest or TCG mode. This patch makes -device virtio-scsi-ccw,iothread=iothread0 work even when KVM is disabled. Currently we don't have an equivalent to "memory: emulate ioeventfd" for ccw yet, but that this doesn't hurt and qemu-iotests 068 can pass with skipping iothread arguments. I have tested that virtio-scsi-ccw works under tcg both with and without iothread. This patch fixes qemu-iotests 068, which was accidentally merged early despite the dependency on ioeventfd.

The response for query-cpu-definitions didn't include the unavailable-features field, which is used by libvirt to figure out whether a certain cpu model is usable on the host. The unavailable features are now computed by obtaining the host CPU model and comparing it against the known CPU models. The comparison takes into account the generation, the GA level and the feature bitmaps. In the case of a CPU generation/GA level mismatch a feature called "type" is reported to be missing. As a result, the output of virsh domcapabilities would change from something like ... <mode name='custom' supported='yes'> <model usable='unknown'>z10EC-base</model> <model usable='unknown'>z9EC-base</model> <model usable='unknown'>z196.2-base</model> <model usable='unknown'>z900-base</model> <model usable='unknown'>z990</model> ... to ... <mode name='custom' supported='yes'> <model usable='yes'>z10EC-base</model> <model usable='yes'>z9EC-base</model> <model usable='no'>z196.2-base</model> <model usable='yes'>z900-base</model> <model usable='yes'>z990</model> ...

2017-07-05s390x: fix realize inheritance for kvm-flicHalil Pasic
Commit f6f4ce4211 ("s390x: add property adapter_routes_max_batch", 2016-12-09) introduces a common realize (intended to be common for all the subclasses) for flic, but fails to make sure the kvm-flic which had its own is actually calling this common realize. This omission fortunately does not result in a grave problem. The common realize was only supposed to catch a possible programming mistake by validating a value of a property set via the compat machine macros. Since there was no programming mistake we don't need this fixed for stable. Let's fix this problem by making sure kvm flic honors the realize of its parent class. Let us also improve on the error message we would hypothetically emit when the validation fails.

Let's vmstatify virtio_ccw_save_config and virtio_ccw_load_config for flexibility (extending using subsections) and for fun. To achieve this we need to hack the config_vector, which is VirtIODevice (that is common virtio) state, in the middle of the VirtioCcwDevice state representation. This is somewhat ugly, but we have no choice because the stream format needs to be preserved. Almost no changes in behavior. Exception is everything that comes with vmstate like extra bookkeeping about what's in the stream, and maybe some extra checks and better error reporting.

Add CONFIG_TCG around TLB-related functions and structure declarations. Some of these functions are defined in ./accel/tcg/cputlb.c, which will not be linked in if TCG is disabled, and have no stubs; therefore, their callers will also be compiled out for --disable-tcg.

2017-07-04cpu: move interrupt handling out of translate-common.cPaolo Bonzini
translate-common.c will not be available anymore with --disable-tcg, so we cannot leave cpu_interrupt_handler there. Move the TCG-specific handler to accel/tcg/tcg-all.c, and adopt KVM's handler as the default one, since it works just as well for Xen and qtest. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
