2015-03-16pc: Disable vmdesc submission for old machinesAlexander Graf2-0/+2
Older PC machine types might by accident be backwards live migration compatible, but with the new vmdesc self-describing blob in our live migration stream we would break that compatibility. Also users wouldn't expect massive behaviorial differences when updating to a new version of QEMU while retaining their old machine type, especially not potential breakage in tooling around live migration. So disable vmdesc submission for old PC machine types.

2015-03-16migration: Allow to suppress vmdesc submissionAlexander Graf4-4/+34
We now always send a JSON blob describing the migration file format as part of the migration stream. However, some tools built around QEMU have proven to stumble over this. This patch gives the user the chance to disable said self-describing part of the migration stream. To disable vmdesc submission, just add -machine suppress-vmdesc=on to your QEMU command line.

2015-03-16migration: Read JSON VM description on incoming migrationAlexander Graf1-1/+21
One of the really nice things about the VM description format is that it goes over the wire when live migration is happening. Unfortunately QEMU today closes any socket once it sees VM_EOF coming, so we never give the VMDESC the chance to actually land on the wire. This patch makes QEMU read the description as well. This way we ensure that anything wire tapping us in between will get the chance to also interpret the stream. Along the way we also fix virt tests that assume that number_bytes_sent on the sender side is equal to number_bytes_read which was true before the VMDESC patches and is true again with this patch.

2015-03-16linux-user: Access correct register for get/set_tls syscalls on ARM TZ CPUsMikhail Ilyin2-2/+15
When support was added for TrustZone to ARM CPU emulation, we failed to correctly update the support for the linux-user implementation of the get/set_tls syscalls. This meant that accesses to the TPIDRURO register via the syscalls were always using the non-secure copy of the register even if native MRC/MCR accesses were using the secure register. This inconsistency caused most binaries to segfault on startup if the CPU type was explicitly set to one of the TZ-enabled ones like cortex-a15. (The default "any" CPU doesn't have TZ enabled and so is not affected.) Use access_secure_reg() to determine whether we should be using the secure or the nonsecure copy of TPIDRURO when emulating these syscalls.

2015-03-16target-arm: Ignore low bit of PC in M-profile exception returnPeter Maydell1-0/+10
For the ARM M-profile cores, exception return pops various registers including the PC from the stack. The architecture defines that if the lowest bit in the new PC value is set (ie the PC is not halfword aligned) then behaviour is UNPREDICTABLE. In practice hardware implementations seem to simply ignore the low bit, and some buggy RTOSes incorrectly rely on this. QEMU's behaviour was architecturally permitted, but bringing QEMU into line with the hardware behaviour allows more guest code to run. We log the situation as a guest error. This was reported as LP:1428657. Reported-by: Anders Esbensen <anders@lyes.dk> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-03-16target-arm: Fix handling of STM (user) with r15 in register listPeter Maydell1-6/+12
The A32 encoding of LDM distinguishes LDM (user) from LDM (exception return) based on whether r15 is in the register list. However for STM (user) there is no equivalent distinction. We were incorrectly treating "r15 in list" as indicating exception return for both LDM and STM, with the result that an STM (user) involving r15 went into an infinite loop. Fix this; note that the value stored for r15 in this case is the current PC regardless of our current mode.

2015-03-16target-arm: get_phys_addr_lpae: more xn controlAndrew Jones1-30/+100
This patch makes the following changes to the determination of whether an address is executable, when translating addresses using LPAE. 1. No longer assumes that PL0 can't execute when it can't read. It can in AArch64, a difference from AArch32. 2. Use va_size == 64 to determine we're in AArch64, rather than arm_feature(env, ARM_FEATURE_V8), which is insufficient. 3. Add additional XN determinants - NS && is_secure && (SCR & SCR_SIF) - WXN && (prot & PAGE_WRITE) - AArch64: (prot_PL0 & PAGE_WRITE) - AArch32: UWXN && (prot_PL0 & PAGE_WRITE) - XN determination should also work in secure mode (untested) - XN may even work in EL2 (currently impossible to test) 4. Cleans up the bloated PAGE_EXEC condition - by removing it. The helper get_S1prot is introduced. It may even work in EL2, when support for that comes, but, as the function name implies, it only works for stage 1 translations.

2015-03-16target-arm: fix get_phys_addr_v6/SCTLR_AFE access checkAndrew Jones1-7/+42
Introduce simple_ap_to_rw_prot(), which has the same behavior as ap_to_rw_prot(), but takes the 2-bit simple AP[2:1] instead of the 3-bit AP[2:0]. Use this in get_phys_addr_v6 when SCTLR_AFE is set, as that bit indicates we should be using the simple AP format. It's unlikely this path is getting used. I don't see CR_AFE getting used by Linux, so possibly not. If it had been, then the check would have been wrong for all but AP[2:1] = 0b11. Anyway, this should fix it up, in case it ever does get used.

More and more virtual machine specifics between kvm and qemu will be transferred with vm attributes. So we encapsulate the common logic in a generic function. Additionally we need only to check during initialization if kvm supports virtual machine attributes.

2015-03-16s390x/kvm: Guest Migration TOD clock synchronizationJason J. Herne4-0/+129
Synchronizes the guest TOD clock across a migration by sending the guest TOD clock value to the destination system. If the guest TOD clock is not preserved across a migration then the guest's view of time will snap backwards if the destination host clock is behind the source host clock. This will cause the guest to hang immediately upon resuming on the destination system. Reviewed-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: Jason J.

2015-03-16s390x: Replace unchecked qdev_init() by qdev_init_nofail()Markus Armbruster1-5/+1
s390_flic_init() is a helper to create and realize either "s390-flic-kvm" or "s390-flic-qemu". When qdev_init() fails, it complains to stderr and succeeds. Except it can't actually fail, because the "s390-flic-qemu" is a dummy without a realize method, and "s390-flic-kvm"'s realize can't fail, even when the kernel device is really unavailable. Odd. Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally obvious, and get rid of the unreachable error reporting.
