2016-08-19test-logging: don't hard-code paths in /tmpSascha Silbe
Since f6880b7f [qemu-log: support simple pid substitution for logs], test-logging creates files with hard-coded names in /tmp. In the best case, this prevents multiple developers from running "make check" on the same machine. In the worst case, it allows for symlink attacks, enabling an attacker to overwrite files that are writable to the developer running "make check". Instead of hard-coding the paths, create a temporary directory using g_dir_make_tmp() and clean it up afterwards.

2016-08-09timer: set vm_clock disabled defaultGonglei
(commit 80dcfb8532ae76343109a48f12ba8ca1c505c179) Upon migration, the code use a timer based on vm_clock for 1ns in the future from post_load to do the event send in case host_connected differs between migration source and target. However, it's not guaranteed that the apic is ready to inject irqs into the guest, and the irq line remained high, resulting in any future interrupts going unnoticed by the guest as well. That's because 1) the migration coroutine is not blocked when it get EAGAIN while reading QEMUFile. 2) The vm_clock is enabled default currently, it doesn't rely on the calling of vm_start(), that means vm_clock timers can run before VCPUs are running. So, let's set the vm_clock disabled default, keep the initial intention of design for vm_clock timers. Meanwhile, change the test-aio usecase, using QEMU_CLOCK_REALTIME instead of QEMU_CLOCK_VIRTUAL as the block code does.

2016-08-08iotests: fix 109Vladimir Sementsov-Ogievskiy
109 iotest is broken for raw after 0965a41e998ab820b5 [mirror: double performance of the bulk stage if the disc is full] The problem is with finishing block-job with error: before specified patch mirror was not very async and it created one big request at disk start, this request finished with error and qemu produced BLOCK_JOB_COMPLETED with zero progress. After 0965a41, mirror starts several smaller requests in parallel, when BLOCK_JOB_COMPLETED emited we have some successful non-zero progress. This patch solves the issue by filtering out progress from 109 test output. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2016-08-05tests: Rename qtests which have names ending "error"Peter Maydell
We have three qtest tests which have test names ending with "error". This is awkward because the output of verbose test runs looks like /crypto/task/error: OK /crypto/task/thread_error: OK which gives false positives if you are grepping build logs for errors by looking for "error:". Since there are only three tests with this problem, just rename them all to 'failure' instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Daniel P.

2016-08-02qht: do not segfault when gathering stats from an uninitialized qhtEmilio G. Cota
So far, QHT functions assume that the passed qht has previously been initialized--otherwise they segfault. This patch makes an exception for qht_statistics_init, with the goal of simplifying calling code. For instance, qht_statistics_init is called from the 'info jit' dump, and given that under KVM the TB qht is never initialized, we get a segfault. Thus, instead of complicating the 'info jit' code with additional checks, let's allow passing an uninitialized qht to qht_statistics_init. While at it, add a test for this to test-qht. Before the patch (for $ qemu -enable-kvm [...]): (qemu) info jit [...] direct jump count 0 (0%) (2 jumps=0 0%) Program received signal SIGSEGV, Segmentation fault. After the patch the "TB hash buckets", "TB hash occupancy" and "TB hash avg chain" lines are omitted.

Given the freeze status, these are all bugfixes, with two exceptions: * There's some final rework of the vcpu hotplug model. Specifically we add spapr specific code on the generic basis Igor established to make cpu_index stable for pseries-2.7 and later machine types. - This allows us to remove the limitation that cpu cores had to be inserted in linear order, and removed in LIFO order. - This is worth merging this late in 2.7 because it will avoid considerable future grief with management layers needing to discover whether out-of-order hotplug is possible, amongst other things. - For now we do add a constraint that the initial cpu cannot be unplugged. * We add two extra testcases to make check, for postcopy and drive_del on ppc64. - Not strictly bugfixes, but safe, because they don't affect the actual code, and increase test coverage. # gpg: Signature made Fri 29 Jul 2016 05:50:02 BST # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: WARNING: This key is not certified with sufficiently trusted signatures! # gpg: It is not certain that the signature belongs to the owner. # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.7-20160729: tests: add drive_del-test to ppc/ppc64 spapr: Prevent boot CPU core removal ppc: Fix fault PC reporting for lve*/stve* VMX instructions test: port postcopy test to ppc64 Revert "spapr: Ensure CPU cores are added contiguously and removed in LIFO order" spapr: init CPUState->cpu_index with index relative to core-id Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2016-07-22tests: introduce a framework for testing migration performanceDaniel P. Berrange
This introduces a moderately general purpose framework for testing performance of migration. The initial guest workload is provided by the included 'stress' program, which is configured to spawn one thread per guest CPU and run a maximally memory intensive workload. It will loop over GB of memory, xor'ing each byte with data from a 4k array of random bytes. This ensures heavy read and write load across all of guest memory to stress the migration performance. While running the 'stress' program will record how long it takes to xor each GB of memory and print this data for later reporting. The test engine will spawn a pair of QEMU processes, either on the same host, or with the target on a remote host via ssh, using the host kernel and a custom initrd built with 'stress' as the /init binary. Kernel command line args are set to ensure a fast kernel boot time (< 1 second) between launching QEMU and the stress program starting execution. None the less, the test engine will initially wait N seconds for the guest workload to stablize, before starting the migration operation. When migration is running, the engine will use pause, post-copy, autoconverge, xbzrle compression and multithread compression features, as well as downtime & bandwidth tuning to encourage completion. If migration completes, the test engine will wait N seconds again for the guest workooad to stablize on the target host. If migration does not complete after a preset number of iterations, it will be aborted. While the QEMU process is running on the source host, the test engine will sample the host CPU usage of QEMU as a whole, and each vCPU thread. While migration is running, it will record all the stats reported by 'query-migration'. Finally, it will capture the output of the stress program running in the guest. All the data produced from a single test execution is recorded in a structured JSON file. A separate program is then able to create interactive charts using the "plotly" python + javascript libraries, showing the characteristics of the migration. The data output provides visualization of the effect on guest vCPU workloads from the migration process, the corresponding vCPU utilization on the host, and the overall CPU hit from QEMU on the host. This is correlated from statistics from the migration process, such as downtime, vCPU throttling and iteration number. While the tests can be run individually with arbitrary parameters, there is also a facility for producing batch reports for a number of pre-defined scenarios / comparisons, in order to be able to get standardized results across different hardware configurations (eg TCP vs RDMA, or comparing different VCPU counts / memory sizes, etc). To use this, first you must build the initrd image $ make tests/migration/initrd-stress.img To run a a one-shot test with all default parameters $ ./tests/migration/guestperf.py > result.json This has many command line args for varying its behaviour. For example, to increase the RAM size and CPU count and bind it to specific host NUMA nodes $ ./tests/migration/guestperf.py \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 \ > result.json Using mem + cpu binding is strongly recommended on NUMA machines, otherwise the guest performance results will vary wildly between runs of the test due to lucky/unlucky NUMA placement, making sensible data analysis impossible. To make it run across separate hosts: $ ./tests/migration/guestperf.py \ --dst-host somehostname > result.json To request that post-copy is enabled, with switchover after 5 iterations $ ./tests/migration/guestperf.py \ --post-copy --post-copy-iters 5 > result.json Once a result.json file is created, a graph of the data can be generated, showing guest workload performance per thread and the migration iteration points: $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu result.json To further include host vCPU utilization and overall QEMU utilization $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu \ --qemu-cpu --vcpu-cpu result.json NB, the 'guestperf-plot.py' command requires that you have the plotly python library installed. eg you must do $ pip install --user plotly Viewing the result.html file requires that you have the plotly.min.js file in the same directory as the HTML output. This js file is installed as part of the plotly python library, so can be found in $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js The guestperf-plot.py program can accept multiple json files to plot, enabling results from different configurations to be compared. Finally, to run the entire standardized set of comparisons $ ./tests/migration/guestperf-batch.py \ --dst-host somehost \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 --output tcp-somehost-4gb-2cpu will store JSON files from all scenarios in the directory named tcp-somehost-4gb-2cpu Signed-off-by: Daniel P.

2016-07-20tests/docker/dockerfiles: new debian-bootstrap.dockerAlex Bennée
Together with the debian-bootstrap.pre script can now build an arbitrary architecture of Debian using debootstrap. This allows debootstrap to set up its first stage before the container is built. To build a container you need a command line like: DEB_ARCH=armhf DEB_TYPE=testing \ ./tests/docker/docker.py build \ --include-executable=arm-linux-user/qemu-arm debian:armhf \ ./tests/docker/dockerfiles/debian-bootstrap.docker Although a number of non-debian systems package the debootstrap script it is fairly portable in itself. Assuming we have some sort of fakeroot implementation we can just clone the upstream repository and use the script from there.

2016-07-19qapi: Implement boxed types for commands/eventsEric Blake
Turn on the ability to pass command and event arguments in a single boxed parameter, which must name a non-empty type (although the type can be a struct with all optional members). For structs, it makes it possible to pass a single qapi type instead of a breakout of all struct members (useful if the arguments are already in a struct or if the number of members is large); for other complex types, it is now possible to use a union or alternate as the data for a command or event. The empty type may be technically feasible if needed down the road, but it's easier to forbid it now and relax things to allow it later, than it is to allow it now and have to special case how the generated 'q_empty' type is handled (see commit 7ce106a9 for reasons why nothing is generated for the empty type). An alternate type is never considered empty, but now that a boxed type can be either an object or an alternate, we have to provide a trivial QAPISchemaAlternateType.is_empty(). The new call to arg_type.is_empty() during QAPISchemaCommand.check() requires that we first check the type in question; but there is no chance of introducing a cycle since objects do not refer back to commands. We still have a split in syntax checking between ad-hoc parsing up front (merely validates that 'boxed' has a sane value) and during .check() methods (if 'boxed' is set, then 'data' must name a non-empty user-defined type). Generated code is unchanged, as long as no client uses the new feature.

2016-07-19qapi: Plumb in 'boxed' to qapi generator lower levelsEric Blake
The next patch will add support for passing a qapi union type as the 'data' of a command. But to do that, the user function for implementing the command, as called by the generated marshal command, must take the corresponding C struct as a single boxed pointer, rather than a breakdown into one parameter per member. Even without a union, being able to use a C struct rather than a list of parameters can make it much easier to handle coding with QAPI. This patch adds the internal plumbing of a 'boxed' flag associated with each command and event. In several cases, this means adding indentation, with one new dead branch and the remaining branch being the original code more deeply nested; this was done so that the new implementation in the next patch is easier to review without also being mixed with indentation changes. For this patch, no behavior or generated output changes, other than the testsuite outputting the value of the new flag (always False for now).

2016-07-19qapi: Require all branches of flat union enum to be coveredEric Blake
We were previously enforcing that all flat union branches were found in the corresponding enum, but not that all enum values were covered by branches. The resulting generated code would abort() if the user passes the uncovered enum value. We don't automatically treat non-present branches in a flat union as empty types, for symmetry with simple unions (there, the enum type is generated from the list of all branches, so there is no way to omit a branch but still have it be part of the union). A later patch will add shorthand so that branches that are empty in flat unions can be declared as 'branch':{} instead of 'branch':'Empty', to avoid the need for an otherwise useless explicit empty type. [Such shorthand for simple unions is a bit harder to justify, since we would still have to generate a wrapper type that parses 'data':{}, rather than truly being an empty branch with no additional siblings to the 'type' member.] Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <1468468228-27827-3-git-send-email-eblake@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2016-07-18block: ignore flush requests when storage is cleanEvgeny Yakovlev
Some guests (win2008 server for example) do a lot of unnecessary flushing when underlying media has not changed. This adds additional overhead on host when calling fsync/fdatasync. This change introduces a write generation scheme in BlockDriverState. Current write generation is checked against last flushed generation to avoid unnessesary flushes. The problem with excessive flushing was found by a performance test which does parallel directory tree creation (from 2 processes). Results improved from 0.424 loops/sec to 0.432 loops/sec. Each loop creates 10^3 directories with 10 files in each. This affected some blkdebug testcases that were expecting error logs from failure-injected flushes which are now skipped entirely (tests 026 071 089). This also affects the performance of block jobs and thus BLOCK_JOB_READY events for driver-mirror and active block-commit commands now arrives faster, before QMP send successfully returns to caller (tests 141 144).

2016-07-13coroutine: move entry argument to qemu_coroutine_createPaolo Bonzini
In practice the entry argument is always known at creation time, and it is confusing that sometimes qemu_coroutine_enter is used with a non-NULL argument to re-enter a coroutine (this happens in block/sheepdog.c and tests/test-coroutine.c). So pass the opaque value at creation time, for consistency with e.g. aio_bh_new. Mostly done with the following semantic patch: @ entry1 @ expression entry, arg, co; @@ - co = qemu_coroutine_create(entry); + co = qemu_coroutine_create(entry, arg); ... - qemu_coroutine_enter(co, arg); + qemu_coroutine_enter(co); @ entry2 @ expression entry, arg; identifier co; @@ - Coroutine *co = qemu_coroutine_create(entry); + Coroutine *co = qemu_coroutine_create(entry, arg); ... - qemu_coroutine_enter(co, arg); + qemu_coroutine_enter(co); @ entry3 @ expression entry, arg; @@ - qemu_coroutine_enter(qemu_coroutine_create(entry), arg); + qemu_coroutine_enter(qemu_coroutine_create(entry, arg)); @ reentry @ expression co; @@ - qemu_coroutine_enter(co, NULL); + qemu_coroutine_enter(co); except for the aforementioned few places where the semantic patch stumbled (as expected) and for test_co_queue, which would otherwise produce an uninitialized variable warning.

2016-07-13blockjob: Add 'job_id' parameter to block_job_create()Alberto Garcia
When a new job is created, the job ID is taken from the device name of the BDS. This patch adds a new 'job_id' parameter to let the caller provide one instead. This patch also verifies that the ID is always unique and well-formed. This causes problems in a couple of places where no ID is being set, because the BDS does not have a device name. In the case of test_block_job_start() (from test-blockjob-txn.c) we can simply use this new 'job_id' parameter to set the missing ID. In the case of img_commit() (from qemu-img.c) we still don't have the API to make commit_active_start() set the job ID, so we solve it by setting a default value. We'll get rid of this as soon as we extend the API.
