2015-07-16crypto: avoid undefined behavior in nettle callsRadim Krčmář
Calling a function pointer that was cast from an incompatible function results in undefined behavior. 'void *' isn't compatible with 'struct XXX *', so we can't cast to nettle_cipher_func, but have to provide a wrapper. (Conversion from 'void *' to 'struct XXX *' might require computation, which won't be done if we drop argument's true type, and pointers can have different sizes so passing arguments on stack would bug.) Having two different prototypes based on nettle version doesn't make this solution any nicer.

In nettle 3, cbc_encrypt() accepts 'nettle_cipher_func' instead of 'nettle_crypt_func' and these two differ in 'const' qualifier of the first argument.

2015-07-16memory: fix refcount leak in memory_region_presentPaolo Bonzini
memory_region_present() leaks a reference to a MemoryRegion in the case "mr == container". While fixing it, avoid reference counting altogether for memory_region_present(), by using RCU only. The return value could in principle be already invalid immediately after memory_region_present returns, but presumably the caller knows that and it's using memory_region_present to probe for devices that are unpluggable, or something like that. The RCU critical section is needed anyway, because it protects as->current_map. Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-07-15target-i386: emulate CPUID level of real hardwareRadim Krčmář
W10 insider has a bug where it ignores CPUID level and interprets CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported instructions. While it's a Windows bug, there is no reason to emulate incorrect level. I used http://instlatx64.atw.hu/ as a source of CPUID and checked that it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M, and Haswell i5-4670T. kvm64 and qemu64 were bumped to 0xD to allow all available features for them (and to avoid the same Windows bug).

2015-07-15hw/arm/boot: Increase fdt alignmentAlexander Graf
The Linux kernel on aarch64 creates a page table entry at early bootup that spans the 2MB range on memory spanning the fdt start address: [ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ] This means that when our current 4k alignment happens to fall at the end of the aligned region, Linux tries to access memory that is not mapped. The easy fix is to instead increase the alignment to 2MB, making Linux's logic always succeed. We leave the existing 4k alignment for 32bit kernels to not cause any regressions due to space constraints.

2015-07-15target-arm: Fix broken SCTLR_EL3 resetPeter Maydell
The SCTLR_EL3 cpreg definition was implicitly resetting the register state to 0, which is both wrong and clashes with the reset done via the SCTLR definition (since sctlr[3] is unioned with sctlr_s). This went unnoticed until recently, when an unrelated change (commit a903c449b41f105aa) happened to perturb the order of enumeration through the cpregs hashtable for reset such that the erroneous reset happened after the correct one rather than before it. Fix this by marking SCTLR_EL3 as an alias, so its reset is left up to the AArch32 view. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.

When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU currently reports the aligned address in CP0 BadVAddr, while the Windows NT kernel expects the unaligned address. This patch adds a byte access with the unaligned address at the beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page fault and fill the QEMU TLB.

2015-07-15linux-user: Fix MIPS N64 trap and break instruction bugAndrew Bennett
For the MIPS N64 ABI when QEMU reads the break/trap instruction so that it can inspect the break/trap code it reads 8 rather than 4 bytes which means it finds the code field from the instruction after the break/trap instruction. This then causes the break/trap handling code to fail because it does not understand the code number. The fix forces QEMU to always read 4 bytes of instruction data rather than deciding how much to read based on the ABI.

2015-07-14block/curl: Don't lose original error when a connection fails.Richard W.M. Jones
Currently if qemu is connected to a curl source (eg. web server), and the web server fails / times out / dies, you always see a bogus EIO "Input/output error". For example, choose a large file located on any local webserver which you control: $ qemu-img convert -p http://example.com/large.iso /tmp/test Once it starts copying the file, stop the webserver and you will see qemu-img fail with: qemu-img: error while reading sector 61440: Input/output error This patch does two things: Firstly print the actual error from curl so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a POSIX.1 compatible errno which more accurately reflects that there was a protocol error, rather than some kind of hardware failure. After this patch is applied, the error changes to: $ qemu-img convert -p http://example.com/large.iso /tmp/test qemu-img: curl: transfer closed with 469989 bytes remaining to read qemu-img: error while reading sector 16384: Protocol error Signed-off-by: Richard W.M.

2015-07-14blockdev: no need to drain in qmp_block_commitPaolo Bonzini
Draining is not necessary, I/O can happen as soon as the commit coroutine yields. Draining can be necessary before reopening the file for read/write, or while modifying the backing file chain, but that is done separately in bdrv_reopen_multiple or bdrv_close; this particular bdrv_drain_all does nothing for that.

2015-07-14block/mirror: Sleep periodically during bitmap scanningFam Zheng
Before, we only yield after initializing dirty bitmap, where the QMP command would return. That may take very long, and guest IO will be blocked. Add sleep points like the later mirror iterations.

2015-07-14watchdog/diag288: correctly register for system reset requestsXu Wang
The diag288 watchdog is no sysbus device, therefore it doesn't get triggered on resets automatically using dc->reset. Let's register the reset handler manually, so we get correctly notified again when a system reset was requested. Also reset the watchdog on subsystem resets that don't trigger a full system reset.

2015-07-14rbd: fix ceph settings precedenceJosh Durgin
Apply the ceph settings from a config file before any ceph settings from the command line. Since the ceph config file location may be specified on the command line, parse it once to read the config file, and do a second pass to apply the rest of the command line ceph options.

2015-07-14rbd: make qemu's cache setting override any ceph settingJosh Durgin
To be safe, when cache=none is used ceph settings should not be able to override it to turn on caching. This was previously possible with rbd_cache=true in the rbd device configuration or a ceph configuration file. Similarly, rbd settings could have turned off caching when qemu requested it, although this would just be a performance problem. Fix this by changing rbd's cache setting to match qemu after all other ceph settings have been applied.
