Also in scsi_bus_legacy_handle_cmdline, report the error when initializing the if=scsi devices, before returning it, because in the callee, error_report is changed to error_setg.

2014-08-20runner: Kill a program under test by time-outMaria Kustova
If a program under test get frozen, the test should finish and report about its failure. In such cases the runner waits for 10 minutes until the program ends its execution. After this time-out the program will be terminated and the test will be marked as failed. For current limitation of test image size to 10 MB as a maximum an execution of each command takes about several seconds in general, so 10 minutes is enough to discriminate freeze, but not drastically increase an overall test duration.

2014-08-15image-fuzzer: Reduce number of generator functions in __init__Maria Kustova
Some issues can be found only when a fuzzed image has a partial structure, e.g. has L1/L2 tables but no refcount ones. Generation of an entirely defined image limits these cases. Now the Image constructor creates only a header and a backing file name (if any), other image elements are generated in the 'create_image' API.

2014-08-15image-fuzzer: Fuzzing functions for qcow2 imagesMaria Kustova
The fuzz submodule of the qcow2 image generator contains fuzzing functions for image fields. Each fuzzing function contains a list of constraints and a call of a helper function that randomly selects a fuzzed value satisfied to one of constraints. For now constraints include only known as invalid or potentially dangerous values. But after investigation of code coverage by fuzz tests they will be expanded by heuristic values based on inner checks and flows of a program under test. Now fuzzing of a header, header extensions and a backing file name is supported.

2014-08-15image-fuzzer: Tool for fuzz tests executionMaria Kustova

The test runner doesn't depend on an image format, so it can be used with any external image generator.

2014-08-15test-coroutine: add baseline test that times the cost of function callsPaolo Bonzini
This can be used to compute the cost of coroutine operations. In the end the cost of the function call is a few clock cycles, so it's pretty cheap for now, but it may become more relevant as the coroutine code is optimized. For example, here are the results on my machine: Function call 100000000 iterations: 0.173884 s Yield 100000000 iterations: 8.445064 s Lifecycle 1000000 iterations: 0.098445 s Nesting 10000 iterations of 1000 depth each: 7.406431 s One yield takes 83 nanoseconds, one enter takes 97 nanoseconds, one coroutine allocation takes (roughly, since some of the allocations in the nesting test do hit the pool) 739 nanoseconds: (8.445064 - 0.173884) * 10^9 / 100000000 = 82.7 (0.098445 * 100 - 0.173884) * 10^9 / 100000000 = 96.7 (7.406431 * 10 - 0.173884) * 10^9 / 100000000 = 738.9 Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2014-07-28acpi-dsdt: procedurally generate _PRTPaolo Bonzini
This replaces the _PRT constant with a method that computes it. The problem is that the DSDT+SSDT have grown from 2.0 to 2.1, enough to cross the 8k barrier (we align the ACPI tables to 4k before putting them in fw_cfg). This causes problems with migration and the pc-i440fx-2.0 machine type. The solution to the problem is to hardcode 64k as the limit, but this doesn't solve the bug with pc-i440fx-2.0. The fix will be for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the ACPI tables. First, however, we must make the actual AML equal or smaller; to do this, rewrite _PRT in a way that saves over 1k of bytecode.
