2019-03-18qmp: common 'id' handling & make QGA conform to QMP specMarc-André Lureau
Let qmp_dispatch() copy the 'id' field. That way any qmp client will conform to the specification, including QGA. Furthermore, it simplifies the work for qemu monitor.

2019-03-12file-posix: Make auto-read-only dynamicKevin Wolf
Until now, with auto-read-only=on we tried to open the file read-write first and if that failed, read-only was tried. This is actually not good enough for libvirt, which gives QEMU SELinux permissions for read-write only as soon as it actually intends to write to the image. So we need to be able to switch between read-only and read-write at runtime. This patch makes auto-read-only dynamic, i.e. the file is opened read-only as long as no user of the node has requested write permissions, but it is automatically reopened read-write as soon as the first writer is attached. Conversely, if the last writer goes away, the file is reopened read-only again. bs->read_only is no longer set for auto-read-only=on files even if the file descriptor is opened read-only because it will be transparently upgraded as soon as a writer is attached. This changes the output of qemu-iotests 232. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2019-03-12file-posix: Fix bdrv_open_flags() for snapshot=onKevin Wolf
Using a different read-only setting for bs->open_flags than for the flags to the driver's open function is just inconsistent and a bad idea. After this patch, the temporary snapshot keeps being opened read-only if read-only=on,snapshot=on is passed. If we wanted to change this behaviour to make only the orginal image file read-only, but the temporary overlay read-write (as the comment in the removed code suggests), that change would have to be made in bdrv_temp_snapshot_options() (where the comment suggests otherwise). Addressing this inconsistency before introducing dynamic auto-read-only is important because otherwise we would immediately try to reopen the temporary overlay even though the file is already unlinked.

2019-03-12block/dirty-bitmap: add recording and busy propertiesJohn Snow

Locked: no successor, qmp_locked. may or may not be enabled. Disabled: Not frozen or locked, disabled. Active: Not frozen, locked, or disabled. The problem is that both "Frozen" and "Locked" mean nearly the same thing, and that both of them do not intuit whether they are recording guest writes or not.

2019-03-12ahci-test: Drop dependence on global_qtestEric Blake
Managing parallel connections to two different monitors via the implicit global_qtest makes it hard to copy-and-paste code to tests that are not aware of the implicit state; the management of global_qtest is even harder to follow because it was masked behind set_context(). Instead, explicitly pass QTestState* around (generally, by reusing the member already present in ahci->parent QOSState), and call explicit qtest_* functions on all places that interact with a monitor. We can assert that the conversion is correct by checking that global_qtest remains NULL throughout the test (a later patch that changes global_qtest to not be a public global variable will drop the assertions).

2019-03-12Suppress test warnings about missing Spectre/Meltdown mitigations with TCGDavid Gibson
The new pseries-4.0 machine type defaults to enabling Spectre/Meltdown mitigations. Unfortunately those mitigations aren't implemented for TCG because we're not yet sure if they're necessary or how to implement them. We don't fail fatally, but we do warn in this case, because it is quite plausible that Spectre/Meltdown can be exploited through TCG (at least for the guest to get access to the qemu address space). This create noise in our testcases though. So, modify the affected tests to explicitly disable the mitigations to suppress these warnings. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
