2013-07-29target-mips: fix mipsdsp_mul_q31_q31Petar Jovanovic
Multiplication of two fractional word elements is not correct when sign extension/promotion is needed. This change fixes it by adding correct casts from unsigned to signed values. In addition, the tests (dpaq_sa_l_w.c and dpsq_sa_l_w.c) have been extended to trigger the current issue.

Multiplication of Q15 fractional halfword vectors was incorrect in the previous implementation of mipsdsp_rndq15_mul_q15_q15. It failed to take element signs into account. This change fixes it, and it adds a test case for it. The change also removes unnecessary cast in the function mipsdsp_mul_q15_q15_overflowflag21().

2013-07-15block: Don't parse protocol from file.filenameKevin Wolf
One of the major reasons for doing something new for -blockdev and blockdev-add was that the old block layer code parses filenames instead of just taking them literally. So we should really leave it untouched when it's passing using the new interfaces (like -drive file.filename=...). This allows opening relative file names that contain a colon.

2013-07-15blockdev: add sync mode to drive-backup QMP commandStefan Hajnoczi
The drive-backup command is similar to the drive-mirror command, except no guest data written after the command executes gets copied. Add a sync mode argument which determines whether the entire disk is copied, just allocated clusters, or only clusters being written to by the guest. Currently only sync mode 'full' is supported - it copies the entire disk. For read-only point-in-time snapshots we may only need sync mode 'none' since the target can be a qcow2 file using the guest's disk as its backing file (no need to copy the entire disk). Finally, sync mode 'top' is useful if we wish to preserve the backing chain. Note that this patch just adds the sync mode argument to drive-backup. It does not implement sync modes 'top' or 'none'. This patch is necessary so we can add a drive-backup HMP command that behaves like the existing drive-mirror HMP command and takes a sync mode.

2013-06-14ide-test: fix failure for test_flushMichael Roth
bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY flag is set when a flush request is in flight. It does this by setting a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE. It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset. The actual unsetting of BSY does not occur until ide_flush_cb gets called in a bh, however, so in some cases this check will race with the actual completion. Fix this by polling the ide status register until BSY flag gets unset before we do our final sanity checks. According to f68ec8379e88502b4841a110c070e9b118d3151c this is in line with how a guest would determine whether or not the device is still busy.

2013-05-30qapi: pad GenericList value fields to 64 bitsMichael Roth
With the introduction of native list types, we now have types such as int64List where the 'value' field is not a pointer, but the actual 64-bit value. On 32-bit architectures, this can lead to situations where 'next' field offset in GenericList does not correspond to the 'next' field in the types that we cast to GenericList when using the visit_next_list() interface, causing issues when we attempt to traverse linked list structures of these types. To fix this, pad the 'value' field of GenericList and other schema-defined/native *List types out to 64-bits. This is less memory-efficient for 32-bit architectures, but allows us to continue to rely on list-handling interfaces that target GenericList to simply visitor implementations. In the future we can improve efficiency by defaulting to using native C array backends to handle list of non-pointer types, which would be more memory efficient in itself and allow us to roll back this change.

2013-05-29tests: set MALLOC_PERTURB_ to expose memory bugsStefan Hajnoczi
glibc wipes malloc(3) memory when the MALLOC_PERTURB_ environment variable is set. The value of the environment variable determines the bit pattern used to wipe memory. For more information, see http://udrepper.livejournal.com/11429.html. Set MALLOC_PERTURB_ for gtester and qemu-iotests. Note we pick a random value from 1 to 255 to expose more bugs. If you need to reproduce a crash use 'show environment' in gdb to extract the MALLOC_PERTURB_ value from a core dump. Both make check and qemu-iotests pass with MALLOC_PERTURB_ enabled.
