The sources for x86_64 are shared in the i386 directory which will be included thanks to TARGET_BASE_ARCH. However not all sources build so we need to filter out the ones we can't build in the 64 bit world and those that can't be built for 32 bit.

While you can construct a compile command that does work using the x86_64 host compiler that most people use this is flakey. Different distros handle this is different ways so we default to using a known good i386 compiler via docker.

2018-06-20tests/tcg/multiarch: don't hard code paths/ports for linux-testAlex Bennée
The fixed path and ports get in the way of running our tests and builds in parallel. Instead of using TESTPATH we use mkdtemp() and instead of a fixed port we allow the kernel to assign one and query it afterwards. Ideally test directory creation should be common functionally across all TCG tests but this could complicate an already huge patch series so we mark it as a TODO for next time.

2018-06-20tests/tcg/multiarch: enable additional linux-test testsAlex Bennée
Un-comment the remaining tests. I removed the itimer value tests because I'm fairly sure a re-arming timer will always have a different value in it when you grab it. I've also fixed up the clone thread flags as QEMU will only allow a clone to use flags which match glibc. However the test is still racey so it remains disabled by default - it can be run by passing any additional parameters on the command line.

2018-06-18block/mirror: Add active mirroringMax Reitz
This patch implements active synchronous mirroring. In active mode, the passive mechanism will still be in place and is used to copy all initially dirty clusters off the source disk; but every write request will write data both to the source and the target disk, so the source cannot be dirtied faster than data is mirrored to the target. Also, once the block job has converged (BLOCK_JOB_READY sent), source and target are guaranteed to stay in sync (unless an error occurs). Active mode is completely optional and currently disabled at runtime. A later patch will add a way for users to enable it.

2018-06-18test-hbitmap: Add non-advancing iter_next testsMax Reitz
Add a function that wraps hbitmap_iter_next() and always calls it in non-advancing mode first, and in advancing mode next. The result should always be the same. By using this function everywhere we called hbitmap_iter_next() before, we should get good test coverage for non-advancing hbitmap_iter_next().

2018-06-18block: Generalize should_update_child() ruleMax Reitz
Currently, bdrv_replace_node() refuses to create loops from one BDS to itself if the BDS to be replaced is the backing node of the BDS to replace it: Say there is a node A and a node B. Replacing B by A means making all references to B point to A. If B is a child of A (i.e. A has a reference to B), that would mean we would have to make this reference point to A itself -- so we'd create a loop. bdrv_replace_node() (through should_update_child()) refuses to do so if B is the backing node of A. There is no reason why we should create loops if B is not the backing node of A, though. The BDS graph should never contain loops, so we should always refuse to create them. If B is a child of A and B is to be replaced by A, we should simply leave B in place there because it is the most sensible choice. A more specific argument would be: Putting filter drivers into the BDS graph is basically the same as appending an overlay to a backing chain. But the main child BDS of a filter driver is not "backing" but "file", so restricting the no-loop rule to backing nodes would fail here.

2018-06-18block/mirror: Use source as a BdrvChildMax Reitz
With this, the mirror_top_bs is no longer just a technically required node in the BDS graph but actually represents the block job operation. Also, drop MirrorBlockJob.source, as we can reach it through mirror_top_bs->backing.

2018-06-18block/mirror: Use CoQueue to wait on in-flight opsMax Reitz
Attach a CoQueue to each in-flight operation so if we need to wait for any we can use it to wait instead of just blindly yielding and hoping for some operation to wake us. A later patch will use this infrastructure to allow requests accessing the same area of the virtual disk to specifically wait for each other.
