On a clean build, after generating trace.h, make would recurse into *-*-user without a clue how to build ../trace.o (added to $(obj-y) in Makefile.target) since its generation rule is in the main Makefile. The softmmus are seemingly unaffected because the $(TOOLS), which each have a dependency on $(trace-obj-y), are built first for the build-all target. Add a dependency on $(trace-obj-y) for %-user, as done for the qemu-* tools. Let's be paranoid and do the same for %-softmmu while at it, just in case someone messes with $(TOOLS) or calls the Makefile target directly.

The blkverify block driver makes investigating image format data corruption much easier. A raw image initialized with the same contents as the test image (e.g. qcow2 file) must be provided. The raw image mirrors read/write operations and is used to verify that data read from the test image is correct. See docs/blkverify.txt for more information.

qcow2 used to use bounce buffers for any AIO requests. This does not only imply unnecessary copying, but also unbounded allocations which should be avoided. This patch removes bounce buffers from the normal AIO write path. Encrypted images continue to use a bounce buffer, however with constant size. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

IDE is a bit ugly in this respect. For one it doesn't really keep track of a sector size - most of the protocol is in units of 512 bytes, and we assume 2048 bytes for CDROMs which is correct most of the time. Second IDE allocates an I/O buffer long before we know if we're dealing with a CDROM or not, so increase the alignment for the io_buffer unconditionally.

Allocation and deallocation of bs->opaque is not in the control of a block driver. Therefore it should not set bs->opaque to a data structure used by another bs, or closing the image will lead to a double free. Signed-off-by: NKevin Wolf <mail@kevin-wolf.de>

vvfat tries to set the readonly flag in its open function, but nowadays this is overwritted with the readonly=... command line option. Check in bdrv_write if the vvfat was opened read-only and return an error in this case. Without this check, vvfat tries to access the qcow bs, which is NULL without enabled write support.

The OpenIndiana (Solaris) e1000g driver drops frames that are too long or too short. It expects to receive frames of at least the Ethernet minimum size. ARP requests in particular are small and will be dropped if they are not padded appropriately, preventing a Solaris VM from becoming visible on the network.

The signedness of enum types depend on the compiler implementation. Therefore the check for negative values may or may not be meaningful. Fix by explicitly casting to a signed integer. Since the values are also checked earlier against event_names table, this is an internal error. Change the 'if' to 'assert'. This also avoids a warning with GCC flag -Wtype-limits.
