2020-07-10target/i386: fix IEEE SSE floating-point exception raisingJoseph Myers
The SSE instruction implementations all fail to raise the expected IEEE floating-point exceptions because they do nothing to convert the exception state from the softfloat machinery into the exception flags in MXCSR. Fix this by adding such conversions. Unlike for x87, emulated SSE floating-point operations might be optimized using hardware floating point on the host, and so a different approach is taken that is compatible with such optimizations. The required invariant is that all exceptions set in env->sse_status (other than "denormal operand", for which the SSE semantics are different from those in the softfloat code) are ones that are set in the MXCSR; the emulated MXCSR is updated lazily when code reads MXCSR, while when code sets MXCSR, the exceptions in env->sse_status are set accordingly. A few instructions do not raise all the exceptions that would be raised by the softfloat code, and those instructions are made to save and restore the softfloat exception state accordingly. Nothing is done about "denormal operand"; setting that (only for the case when input denormals are *not* flushed to zero, the opposite of the logic in the softfloat code for such an exception) will require custom code for relevant instructions, or else architecture-specific conditionals in the softfloat code for when to set such an exception together with custom code for various SSE conversion and rounding instructions that do not set that exception. Nothing is done about trapping exceptions (for which there is minimal and largely broken support in QEMU's emulation in the x87 case and no support at all in the SSE case).

2020-07-06block/vpc: return ZERO block-status when appropriateVladimir Sementsov-Ogievskiy
In case when get_image_offset() returns -1, we do zero out the corresponding chunk of qiov. So, this should be reported as ZERO. Note that this changes visible output of "qemu-img map --output=json" and "qemu-io -c map" commands. For qemu-img map, the change is obvious: we just mark as zero what is really zero. For qemu-io it's less obvious: what was unallocated now is allocated. There is an inconsistency in understanding of unallocated regions in Qemu: backing-supporting format-drivers return 0 block-status to report go-to-backing logic for this area. Some protocol-drivers (iscsi) return 0 to report fs-unallocated-non-zero status (i.e., don't occupy space on disk, read result is undefined). BDRV_BLOCK_ALLOCATED is defined as something more close to go-to-backing logic. Still it is calculated as ZERO | DATA, so 0 from iscsi is treated as unallocated. It doesn't influence backing-chain behavior, as iscsi can't have backing file. But it does influence "qemu-io -c map". We should solve this inconsistency at some future point. Now, let's just make backing-not-supporting format drivers (vdi in the previous patch and vpc now) to behave more like backing-supporting drivers and not report 0 block-status. More over, returning ZERO status is absolutely valid thing, and again, corresponds to how the other format-drivers (backing-supporting) work. After block-status update, it never reports 0, so setting unallocated_blocks_are_zero doesn't make sense (as the only user of it is bdrv_co_block_status and it checks unallocated_blocks_are_zero only for unallocated areas). Drop it.

That the luks driver is present is little indication on whether it is actually working. Without the crypto libraries linked in, it does not work. So add this function, which tries to create a luks image to see whether that actually works.

2020-07-06iotests: Make _filter_img_create more activeMax Reitz
Right now, _filter_img_create just filters out everything that looks format-dependent, and applies some filename filters. That means that we have to add another filter line every time some format gets a new creation option. This can be avoided by instead discarding everything and just keeping what we know is format-independent (format, size, backing file, encryption information[1], preallocation) or just interesting to have in the reference output (external data file path). Furthermore, we probably want to sort these options. Format drivers are not required to define them in any specific order, so the output is effectively random (although this has never bothered us until now). We need a specific order for our reference outputs, though. Unfortunately, just using a plain "sort" would change a lot of existing reference outputs, so we have to pre-filter the option keys to keep our existing order (fmt, size, backing*, data, encryption info, preallocation). Finally, this makes it difficult for _filter_img_create to automagically work for QMP output. Thus, this patch adds a separate _filter_img_create_for_qmp function that echos every line verbatim that does not start with "Formatting", and pipes those "Formatting" lines to _filter_img_create. [1] Actually, the only thing that is really important is whether encryption is enabled or not. A patch by Maxim thus removes all other "encrypt.*" options from the output: https://lists.nongnu.org/archive/html/qemu-block/2020-06/msg00339.html But that patch needs to come later so we can get away with changing as few reference outputs in this patch here as possible.

2020-07-06qcow2: Fix preallocation on images with unaligned sizesAlberto Garcia
When resizing an image with qcow2_co_truncate() using the falloc or full preallocation modes the code assumes that both the old and new sizes are cluster-aligned. There are two problems with this: 1) The calculation of how many clusters are involved does not always get the right result. Example: creating a 60KB image and resizing it (with preallocation=full) to 80KB won't allocate the second cluster. 2) No copy-on-write is performed, so in the previous example if there is a backing file then the first 60KB of the first cluster won't be filled with data from the backing file. This patch fixes both issues.

2020-06-26i386: Mask SVM features if nested SVM is disabledEduardo Habkost
QEMU incorrectly validates FEAT_SVM feature flags against GET_SUPPORTED_CPUID even if SVM features are being masked out by cpu_x86_cpuid(). This can make QEMU print warnings on most AMD CPU models, even when SVM nesting is disabled (which is the default). This bug was never detected before because of a Linux KVM bug: until Linux v5.6, KVM was not filtering out SVM features in GET_SUPPORTED_CPUID when nested was disabled. This KVM bug was fixed in Linux v5.7-rc1, on Linux commit a50718cc3f43 ("KVM: nSVM: Expose SVM features to L1 iff nested is enabled"). Fix the problem by adding a CPUID_EXT3_SVM dependency to all FEAT_SVM feature flags in the feature_dependencies table.

2020-06-26target/i386: reimplement fyl2xp1 using floatx80 operationsJoseph Myers
The x87 fyl2xp1 emulation is currently based around conversion to double. This is inherently unsuitable for a good emulation of any floatx80 operation, even before considering that it is a particularly naive implementation using double (adding 1 then using log rather than attempting a better emulation using log1p). Reimplement using the soft-float operations, as was done for f2xm1; as in that case, m68k has related operations but not exactly this one and it seemed safest to implement directly rather than reusing the m68k code to avoid accumulation of errors. A test is included with many randomly generated inputs. The assumption of the test is that the result in round-to-nearest mode should always be one of the two closest floating-point numbers to the mathematical value of y * log2(x + 1); the implementation aims to do somewhat better than that (about 70 correct bits before rounding). I haven't investigated how accurate hardware is. Intel manuals describe a narrower range of valid arguments to this instruction than AMD manuals. The implementation accepts the wider range (it's needed anyway for the core code to be reusable in a subsequent patch reimplementing fyl2x), but the test only has inputs in the narrower range so that it's valid on hardware that may reject or produce poor results for inputs outside that range. Code in the previous implementation that sets C2 for some out-of-range arguments is not carried forward to the new implementation; C2 is undefined for this instruction and I suspect that code was just cut-and-pasted from the trigonometric instructions (fcos, fptan, fsin, fsincos) where C2 *is* defined to be set for out-of-range arguments.

2020-06-26target/i386: reimplement f2xm1 using floatx80 operationsJoseph Myers
The x87 f2xm1 emulation is currently based around conversion to double. This is inherently unsuitable for a good emulation of any floatx80 operation, even before considering that it is a particularly naive implementation using double (computing with pow and then subtracting 1 rather than attempting a better emulation using expm1). Reimplement using the soft-float operations, including additions and multiplications with higher precision where appropriate to limit accumulation of errors. I considered reusing some of the m68k code for transcendental operations, but the instructions don't generally correspond exactly to x87 operations (for example, m68k has 2^x and e^x - 1, but not 2^x - 1); to avoid possible accumulation of errors from applying multiple such operations each rounding to floatx80 precision, I wrote a direct implementation of 2^x - 1 instead. It would be possible in principle to make the implementation more efficient by doing the intermediate operations directly with significands, signs and exponents and not packing / unpacking floatx80 format for each operation, but that would make it significantly more complicated and it's not clear that's worthwhile; the m68k emulation doesn't try to do that. A test is included with many randomly generated inputs. The assumption of the test is that the result in round-to-nearest mode should always be one of the two closest floating-point numbers to the mathematical value of 2^x - 1; the implementation aims to do somewhat better than that (about 70 correct bits before rounding).
