2015-09-03s390x: Dump storage keys qmp commandJason J. Herne
Provide a dump-skeys qmp command to allow the end user to dump storage keys. This is useful for debugging problems with guest storage key support within Qemu and for guest operating system developers.

2015-09-03s390x: Enable new s390-storage-keys deviceJason J. Herne
s390 guest initialization is modified to make use of new s390-storage-keys device. Old code that globally allocated storage key array is removed. The new device enables storage key access for kvm guests. Cache storage key QOM objects in frequently used helper functions to avoid a performance hit every time we use one of these functions.

2015-09-01Makefile: qemu-ga: fix msi target error messageMichael Roth
'msi' target reports error if we attempt to use it when QEMU hasn't been ./configure'd to enable it. The parenthesis cause an interpreter error if we don't enclose the error in quotes.

2015-09-01build: qemu-ga: fix VSS dependenciesMichael Roth
Currently VSS dll/tlb files for use in w32 builds are only built as a result of having been added to the general 'tools' target alongside qemu-ga. This is fine for default make target, but if we build qemu-ga directly via `make qemu-ga.exe`, the VSS files are not created. Fix this by moving the VSS dependencies to qemu-ga.exe directly. With this move we can move the VSS files back out of 'tools', and drop the extra handling from MSI target in Makefile. Now we can build qemu-ga MSI package with: ./configure ... make qemu-ga.exe make msi or simply: ./configure ... make msi and no longer need to do a full build beforehand.

2015-09-01configure: qemu-ga: explicitly enable qemu-ga MSI support when probedMichael Roth
Currently, if we don't explicitly disable support for MSI installer via --disable-guest-agent-msi, the configure variable that tracks the flag, 'guest_agent_msi', never gets set unless one of the probes fails. Subsequent code then treats this unset value the same as if it were a "yes" value (via != "no" style checks). Instead, set the default "yes" value explicitly after the probes, then make subsequent code expect the values to be set. This makes it easier to report on whether or not MSI support was enabled via probe by looking at the ./configure summary. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2015-09-01configure: qemu-ga: move MSI installer probe after qga probeMichael Roth
MSI probe assumes that qemu-ga support has been probed already, but in cases where --enable-guest-agent/--disable-guest-agent have not been passed to configure, qemu-ga support may end up getting enabled later, as is the case with w32 builds. This leads to MSI probe prematurely reporting error due to lack of qemu-ga support. Fix this by moving MSI installer probe after the final qga probes.

2015-09-01qemu-ga: Prevent QEMU-GA VSS provider from being unregistered on MSI reinstallLeonid Bloch
Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered. Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

2015-08-26vnc: fix memory corruption (CVE-2015-5225)Gerd Hoffmann
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential memory corruption issues" can become negative. Result is (possibly exploitable) memory corruption. Reason for that is it uses the stride instead of bytes per scanline to apply limits. For the server surface is is actually fine. vnc creates that itself, there is never any padding and thus scanline length always equals stride. For the guest surface scanline length and stride are typically identical too, but it doesn't has to be that way. So add and use a new variable (guest_ll) for the guest scanline length. Also rename min_stride to line_bytes to make more clear what it actually is. Finally sprinkle in an assert() to make sure we never use a negative _cmp_bytes again.

2015-08-25target-arm: Wire up AArch64 EL2 and EL3 address translation opsPeter Maydell
Wire up the AArch64 EL2 and EL3 address translation operations (AT S12E1*, AT S12E0*, AT S1E2*, AT S1E3*), and correct some errors in the ats_write64() function in previously unused code that would have done the wrong kind of lookup for accesses from EL3 when SCR.NS==0.

2015-08-25target-arm: there is no TTBR1 for 32-bit EL2 stage 1 translationsPeter Maydell
For EL2 stage 1 translations, there is no TTBR1. We were already handling this for 64-bit EL2; add the code to take the 'no TTBR1' code path for 64-bit EL2 as well.
