2017-02-14target/openrisc: Tidy ppc/npc implementationRichard Henderson
The NPC SPR is really only supposed to be used for FPGA debugging. It contains the same contents as PC, unless one plays games. Follow the or1ksim implementation in flushing delayed branch state when it is changed. The PPC SPR need not be updated every instruction, merely when we exit the TB or attempt to read its contents.

2017-02-14target/openrisc: Fix exception handling status registersStafford Horne
I am working on testing instruction emulation patches for the linux kernel. During testing I found these 2 issues: - sets DSX (delay slot exception) but never clears it - EEAR for illegal insns should point to the bad exception (as per openrisc spec) but its not This patch fixes these two issues by clearing the DSX flag when not in a delay slot and by setting EEAR to exception PC when handling illegal instruction exceptions. After this patch the openrisc kernel with latest patches boots great on qemu and instruction emulation works.

2017-02-12qemu-img: Use qemu_strtoul() rather than raw strtoul()Peter Maydell
Some of the argument parsing in qemu-img uses strtoul() to parse integer arguments. This is tricky to get correct and in fact the code does not get it right, because it assigns the result of strtoul() to an 'int' variable and then tries to check for > INT_MAX. Coverity correctly complains that the comparison is always false. Rewrite to use qemu_strtoul(), which has a saner convention for reporting conversion failures.

2017-02-12qemu-io: don't allow I/O operations larger than BDRV_REQUEST_MAX_BYTESAlberto Garcia
Passing a request size larger than BDRV_REQUEST_MAX_BYTES to any of the I/O commands results in an error. While 'read' and 'write' handle the error correctly, 'aio_read' and 'aio_write' hit an assertion: blk_aio_read_entry: Assertion `rwco->qiov->size == acb->bytes' failed. The reason is that the QEMU I/O code cannot handle request sizes larger than BDRV_REQUEST_MAX_BYTES, so this patch makes qemu-io check that all values are within range.

2017-02-12qcow2: Optimize the refcount-block overlap checkAlberto Garcia
The metadata overlap checks introduced in a40f1c2add help detect corruption in the qcow2 image by verifying that data writes don't overlap with existing metadata sections. The 'refcount-block' check in particular iterates over the refcount table in order to get the addresses of all refcount blocks and check that none of them overlap with the region where we want to write. The problem with the refcount table is that since it always occupies complete clusters its size is usually very big. With the default values of cluster_size=64KB and refcount_bits=16 this table holds 8192 entries, each one of them enough to map 2GB worth of host clusters. So unless we're using images with several TB of allocated data this table is going to be mostly empty, and iterating over it is a waste of CPU. If the storage backend is fast enough this can have an effect on I/O performance. This patch keeps the index of the last used (i.e. non-zero) entry in the refcount table and updates it every time the table changes. The refcount-block overlap check then uses that index instead of reading the whole table. In my tests with a 4GB qcow2 file stored in RAM this doubles the amount of write IOPS.

2017-02-12block: check full backing filename when searching protocol filenamesJeff Cody
In bdrv_find_backing_image(), if we are searching an image for a backing file that contains a protocol, we currently only compare unmodified paths. However, some management software will change the backing filename to be a relative filename in a path. QEMU is able to handle this fine, because internally it will use path_combine to put together the full protocol URI. However, this can lead to an inability to match an image during a QAPI command that needs to use bdrv_find_backing_image() to find the image, when it is searched by the full URI. When searching for a protocol filename, if the straight comparison fails, this patch will also compare against the full backing filename to see if that is a match.

2017-02-12block/vmdk: Fix the endian problem of buf_len and lbaQingFeng Hao
The problem was triggered by qemu-iotests case 055. It failed when it was comparing the compressed vmdk image with original test.img. The cause is that buf_len in vmdk_write_extent wasn't converted to little-endian before it was stored to disk. But later vmdk_read_extent read it and converted it from little-endian to cpu endian. If the cpu is big-endian like s390, the problem will happen and the data length read by vmdk_read_extent will become invalid! The fix is to add the conversion in vmdk_write_extent, meanwhile, repair the endianness problem of lba field which shall also be converted to little-endian before storing to disk.

2017-02-12qapi: Tweak error message of bdrv_query_image_infoFam Zheng
@bs doesn't always have a device name, such as when it comes from "qemu-img info". Report file name instead. Signed-off-by: Fam Zheng <famz@redhat.com> Message-id: 20170119130759.28319-2-famz@redhat.com Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Max Reitz <mreitz@redhat.com>
2017-02-12qemu-img: Improve commit invalid base messageMax Reitz
When trying to invoke qemu-img commit with a base image file name that is not part of the top image's backing chain, the user receives a rather plain "Base not found" error message. This is not really helpful because it does not explain what "not found" means, potentially leaving the user wondering why qemu cannot find a file despite it clearly existing in the file system. Improve the error message by clarifying that "not found" means "not found in the top image's backing chain".

2017-02-12iotests: Fix a problem in common.filterQingFeng Hao
If TEST_DIR is set to /tmp, test case 144 will fail. The reason is that TEST_DIR resembles 144's test image name tmp.qcow2. When 144 is testing $TEST_DIR/tmp.qcow2, it wants to replace $TEST_DIR/tmp.qcow2 to TEST_DIR/tmp.qcow2, but actually it will fail and get TEST_DIRTEST_DIR.qcow2 in this case. The fix is just to modify the code to replace $TEST_DIR/ with TEST_DIR/.

2017-02-10hw/vfio: Add CONFIG switches for calxeda-xgmac and amd-xgbeThomas Huth
Both devices seem to be specific to the ARM platform. It's confusing for the users if they show up on other target architectures, too (e.g. when the user runs QEMU with "-device ?" to get a list of supported devices). Thus let's introduce proper configuration switches so that the devices are only compiled and included when they are really required.
