* pkg/instance: clean up temp fileDmitry Vyukov2019-03-171-0/+1
|
* pkg/instance: use -fpermissive -w when building old syzkallerDmitry Vyukov2019-03-171-0/+5
| | | | | | | | | Since we can be building very old revisions for bisection here, make the build as permissive as possible. Newer compilers tend to produce more warnings also kernel headers may be broken, e.g.: ebtables.h:197:19: error: invalid conversion from ‘void*’ to ‘ebt_entry_target*’ Update #501
* pkg/instance: use gmake on FreeBSD as on OpenBSDEd Maste2019-02-261-1/+1
|
* pkg/instance: test coverage during instance testingDmitry Vyukov2019-02-131-1/+1
| | | | | | Currently we always pass cover=false during instance testing and as the result covereage is not tested. This can result in broken images. Pass the actual value of coverage for testing.
* vm: allow fine-grained control over program exit conditionsDmitry Vyukov2018-12-241-3/+4
| | | | | | | | | Currently we only support canExit flag. However there are actually 3 separate conditions: - program can exit normally - program can timeout (e.g. fuzzer test or runtest can't) - program can exit with error (e.g. C test can) Allow to specify these 3 conditions separately.
* pkg/instance: make kernel reboot detection portableDmitry Vyukov2018-12-161-11/+9
| | | | The current code is linux specific, generalize it to other OSes.
* syz-ci: use gmake instead of make on openbsdDmitry Vyukov2018-09-131-1/+9
| | | | Update #712
* pkg/instance: support injected boot for vmmDmitry Vyukov2018-09-111-8/+8
| | | | | | | If pkg/build produces a kernel, inject it into vmm config too. This will allow continuous build with vmm VM type. Update #712
* syz-ci: de-hardcode list of VMs that support overcommitDmitry Vyukov2018-09-111-4/+2
| | | | | | | | We currently have this list in multiple places (somewhat diverged). Specify this "overcommit" property in VM implementations. In particular, we also want to allow overcommit for "vmm" type. Update #712
* pkg/instance: fix gometalinter warningsDmitry Vyukov2018-08-291-8/+9
|
* pkg/instance: fix job testingDmitry Vyukov2018-08-292-2/+140
| | | | | New FuzzerCmd generates flags that can't be parsed by an old fuzzer. Fix that and add a test.
* tools/syz-runtest: add tool for program unit testingDmitry Vyukov2018-08-031-4/+4
| | | | | | | | | | | The tool is run as: $ syz-runtest -config manager.config This runs all programs from sys/*/test/* in different modes on actual VMs and checks results. Fixes #603
* pkg/mgrconfig: move from syz-manager/mgrconfigDmitry Vyukov2018-08-021-1/+1
| | | | | | | | mgrconfig was used only by syz-manager initially, but now it's used by a dozen of packages and it's weird to import from under a binary dir. pkg/ is much more reasonable dir for a widely used helper package.
* pkg/instance: pass -os to execprog/fuzzer only for akarosDmitry Vyukov2018-07-061-6/+38
| | | | | | Only akaros needs OS, because the rest assume host OS. But speciying OS for all OSes breaks patch testing on syzbot because old execprog does not have os flag.
* pkg/instance: pass os flag to execprog/fuzzerDmitry Vyukov2018-07-051-4/+4
|
* pkg/instance: fix Accept error checkDmitry Vyukov2018-06-291-1/+1
|
* pkg/build: support fuchsia buildsDmitry Vyukov2018-06-281-1/+35
|
* pkg/vcs: pave way for multi-vcs supportDmitry Vyukov2018-06-271-1/+1
| | | | | Wrap current git interface in abstract interface. Provide constructor that create repo interface for the given os/vm.
* pkg/vcs: move from pkg/gitDmitry Vyukov2018-06-271-2/+2
| | | | Rename pkg/git to pkg/vcs because we need to support not only git.
* syz-fuzzer: partially revert "syz-fuzzer: fix gvisor testing"Dmitry Vyukov2018-06-261-14/+2
| | | | This breaks patch testing on syz-ci as it can use older version of syz-fuzzer.
* syz-fuzzer: fix gvisor testingDmitry Vyukov2018-06-261-3/+15
| | | | | | Testing code wasn't ready to dial stdin. Make it use the same logic rpc package uses to connecto to host.
* pkg/instance: say that gvisor can create instances out of thin airDmitry Vyukov2018-06-231-1/+1
|
* pkg/build: pave way for multi-OS supportDmitry Vyukov2018-06-221-9/+8
| | | | | | Unify kernel and image build, that distinction is really uninteresting. Define interface that each OS needs to implement. Add gvisor stub.
* pkg/build: move from pkg/kernelDmitry Vyukov2018-06-221-3/+3
| | | | Rename pkg/kernel to pkg/build and prepare for multi-OS support.
* pkg/report: allow to specify suppressions per OSDmitry Vyukov2018-06-221-5/+3
| | | | | | | | | | | | | Currently all (linux-specific) suppressions are hardcoded in mgrconfig. This is very wrong. Move them to pkg/report and allow to specify per OS. Add gvisor-specific suppressions. This required a bit of refactoring. Introduce mgrconfig.KernelObj finally. Make report.NewReporter and vm.Create accept mgrconfig directly instead of passing it as multiple scattered args. Remove tools/syz-parse and it always did the same as tools/syz-symbolize. Simplify global vars in syz-manager/cover.go. Create reporter eagerly in manager. Use sort.Slice more. Overall -90 lines removed.
* pkg/report: pass vm type to NewReporterDmitry Vyukov2018-06-221-2/+2
| | | | | For the case when VM type affects output. Will be needed for gvisor. It is kinda linux, but kinda not.
* vm: pass instance to MonitorExecutionDmitry Vyukov2018-06-221-2/+2
| | | | | It may need it later to try to obtain additional diagnostic from hanged instances.
* pkg/instance: more robust instance testingDmitry Vyukov2018-06-111-5/+6
| | | | | | | Strictly saying, we may not get the connection when the fuzzer process exits. The accepting goroutine may have not been scheduled yet. For the connection for up to 10 seconds.
* pkg/csource: allow to build source fom memoryDmitry Vyukov2018-06-061-5/+1
| | | | | | In most cases we have source in memory, so provide a function to build right from memory without creating temp files.
* pkg/kernel: allow to split full make outputDmitry Vyukov2018-05-171-2/+2
| | | | | | | | | | | Currently kernel build failures are insanely verbose (contain full kernel build output) and there is no way to separate short descriptions from full output. Make it possible. Also try to extract failure root cause froom build log. Use this in pkg/bisect to not pollute log on build failures. Update #501
* tools/create-gce-image.sh: support both nbd and loopDmitry Vyukov2018-05-171-6/+7
| | | | | Pass target OS/arch and VM type to kernel.CreateImage. Use nbd for gce and loop for qemu VM type.
* pkg/instance: relax syzkaller path checkDmitry Vyukov2018-05-141-14/+13
| | | | | | Only check that syzkaller path is in GOPATH if we are going to build it. syz-ci image testing does not have syzkaller path in GOPATH, but it also does not build syzkaller.
* pkg/instance: add package for testing of images/patches/bisectionDmitry Vyukov2018-05-141-0/+337
Move helper image/patch testing code from syz-ci/testing.go to a separate package so that it can be reused during bisection. Update #501
