2016-06-17ppc / sparc: Add a tester for checking whether OpenBIOS runs successfullyThomas Huth
Since the mac99 and g3beige PowerPC machines recently broke without being noticed, it would be good to have a tester for "make check" that detects such issues immediately. A simple way to test the firmware of these machines is to use the "-prom-env" parameter of QEMU. This parameter can be used to put some Forth code into the 'boot-command' firmware variable which then can signal success to the tester by writing a magic value to a known memory location. And since some of the Sparc machines are also using OpenBIOS, they are now tested with this prom-env-tester, too.

2016-06-17test: start vhost-user reconnect testMarc-André Lureau
This is a simple reconnect test, that simply checks if vhost-user reconnection is possible and restore the state. A more complete test would actually manipulate and check the ring contents (such extended testing would benefit from the libvhost-user proposed in QEMU list to avoid duplication of ring manipulations) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Victor Kaplansky <victork@redhat.com> Reviewed-by: Michael S.

2016-06-17tests/vhost-user-bridge: workaround stale vring baseMarc-André Lureau
This patch is a similar solution to what Yuanhan Liu/Huawei Xie have suggested for DPDK. When vubr quits (killed or crashed), a restart of vubr would get stale vring base from QEMU. That would break the kernel virtio net completely, making it non-work any more, unless a driver reset is done. So, instead of getting the stale vring base from QEMU, Huawei suggested we could get a proper one from used->idx. This works because the queues packets are processed in order.

2016-06-16block: drop support for using qcow[2] encryption with system emulatorsDaniel P. Berrange
Back in the 2.3.0 release we declared qcow[2] encryption as deprecated, warning people that it would be removed in a future release. commit a1f688f4152e65260b94f37543521ceff8bfebe4 Author: Markus Armbruster <armbru@redhat.com> Date: Fri Mar 13 21:09:40 2015 +0100 block: Deprecate QCOW/QCOW2 encryption The code still exists today, but by a (happy?) accident we entirely broke the ability to use qcow[2] encryption in the system emulators in the 2.4.0 release due to commit 8336aafae1451d54c81dd2b187b45f7c45d2428e Author: Daniel P.

preventing QEMU reading cipher text as if it were plain text, during startup and aborting QEMU to avoid bad usage of this data. For added fun this bug only happens if the encrypted qcow2 file happens to have data written to the first cluster, otherwise the cluster won't be allocated and so qcow2 would not try the decryption routines at all, just return all 0's. That no one even noticed, let alone reported, this bug that has shipped in 2.4.0, 2.5.0 and 2.6.0 shows that the number of actual users of encrypted qcow2 is approximately zero. So rather than fix the crash, and backport it to stable releases, just go ahead with what we have warned users about and disable any use of qcow2 encryption in the system emulators. qemu-img/qemu-io/qemu-nbd are still able to access qcow2 encrypted images for the sake of data conversion. In the future, qcow2 will gain support for the alternative luks format, but when this happens it'll be using the '-object secret' infrastructure for getting keys, which avoids this problematic scenario entirely.

2016-06-11qht: add qht-bench, a performance benchmarkEmilio G. Cota
This serves as a performance benchmark as well as a stress test for QHT. We can tweak quite a number of things, including the number of resize threads and how frequently resizes are triggered. A performance comparison of QHT vs CLHT[1] and ck_hs[2] using this same benchmark program can be found here: http://imgur.com/a/0Bms4 The tests are run on a 64-core AMD Opteron 6376, pinning threads to cores favoring same-socket cores. For each run, qht-bench is invoked with: $ tests/qht-bench -d $duration -n $n -u $u -g $range , where $duration is in seconds, $n is the number of threads, $u is the update rate (0.0 to 100.0), and $range is the number of keys. Note that ck_hs's performance drops significantly as writes go up, since it requires an external lock (I used a ck_spinlock) around every write. Also, note that CLHT instead of using a seqlock, relies on an allocator that does not ever return the same address during the same read-critical section. This gives it a slight performance advantage over QHT on read-heavy workloads, since the seqlock writes aren't there.

2016-06-08block: Switch bdrv_write_zeroes() to byte interfaceEric Blake

2016-06-08qcow2: Catch more unaligned write_zero into zero clusterEric Blake
is_zero_cluster() and is_zero_cluster_top_locked() are used only by qcow2_co_write_zeroes(). The former is too broad (we don't care if the sectors we are about to overwrite are non-zero, only that all other sectors in the cluster are zero), so it needs to be called up to twice but with smaller limits - rename it along with adding the neeeded parameter. The latter can be inlined for more compact code. The testsuite change shows that we now have a sparser top file when an unaligned write_zeroes overwrites the only portion of the backing file with data. Based on a patch proposal by Denis V. Lunev.

2016-06-08block: split write_zeroes alwaysDenis V. Lunev
We should split requests even if they are less than write_zeroes_alignment. For example we can have the following request: offset 62k size 4k write_zeroes_alignment 64k The original code sent 1 request covering 2 qcow2 clusters, and resulted in both clusters being allocated. But by splitting the request, we can cater to the case where one of the two clusters can be zeroed as a whole, for only 1 cluster allocated after the operation. Signed-off-by: Denis V.

2016-06-07docker: Don't use eval trick on MakefileEduardo Habkost
The eval trick for defining DOCKER_SRC_COPY doesn't do anything useful, as DOCKER_SRC_COPY is immediately expanded just after it is defined, and CUR_TIME is already defined using ":=". Simply define it using ":=" so it is evaluated only once. The eval trick was also triggering an weird error on Travis builds: qemu/tests/docker/Makefile.include:34: *** unterminated variable reference. Stop. The issue is not easily reproducible (maybe it's a bug in some versions of Make), but it is avoided if removing the eval trick.

In a similar vein to commit ee2bdc33c913b7d765baa5aa338c29fb30a05c9a ("throttle: refuse bps_max/iops_max without bps/iops") it is likely that the user made a configuration error if iops-size has been set but no iops limit has been set. Print an error message so the user can check their throttling configuration. They should either remove iops-size if they don't want any throttling or specify one of iops-total, iops-read, or iops-write.
