* pkg/build: extract Rust build errorsAleksandr Nogikh2025-11-031-0/+1
| | | | Add a rust error regexp and a test to verify the resulting report.
* tools/docker: install bazelisk instead of bazelKonstantin Bogomolov2025-08-281-1/+4
| | | | | | | The needed Bazel version to build gVisor got bumped. However, instead of doing the same bump in two places whenever this happens, we can simply use bazelisk in syzkaller to determine which bazel version to use automatically.
* all: apply linter auto fixesTaras Madan2025-07-171-7/+8
| | | | ./tools/syz-env bin/golangci-lint run ./... --fix
* pkg/build: add build command for starnixLaura Peskin2024-10-301-0/+2

* pkg/build: share parameters sanitization between builds and cleansFlorent Revest2024-10-151-6/+11
| | | | | | | | | | When refactoring the Clean() function to share more code with Image(), there is logic I forgot to replicate, like setting a default number of CPUs to build/clean with. I imagine that not setting the default tracer could end up being a subtle issue in the future too. To avoid missing these cases in the future, refactor the parameters sanitization into a helper function called by both.
* pkg/build: use the build environment in clean() callsFlorent Revest2024-10-141-5/+5
| | | | | | This unifies the build() and clean() interfaces such that if a custom compiler or make binary is provided in the manager or bisection config, they can be taken into account by the clean() interface.
* pkg/build/linux: support building with a custom make binaryFlorent Revest2024-10-141-0/+1
| | | | | | Certain environments might need a specific make command or wrap make calls with extra logic. This lets users provide a path to a custom make binary.
* pkg/build: handle OOM-killed build errorSabyrzhan Tasbolatov2024-09-231-0/+20
| | | | | | | Handle SIGKILL (exit code = 137) on osutil.Run() during Linux kernel image building and return build.InfraError without reporting. Fixes: https://github.com/google/syzkaller/issues/5317
* all: rename build_jobs to build_cpusAleksandr Nogikh2024-08-221-3/+3
| | | | The latter is a better suitable name.
* pkg/build: introduce the build jobs parameterAleksandr Nogikh2024-08-221-0/+5
| | | | | This parameter defines the number of cores dedicated to the kernel build process. By default, it's equal to the number of available CPUs.
* sys/targets: add consts for gvisor/starnixDmitry Vyukov2024-05-271-1/+1
| | | | | Lint started warning about duplicate "gvisor" const in pkg/cover. Add gvisor/starnix consts to sys/targets package to avoid duplication.
* all: remove akaros supportDmitry Vyukov2024-04-151-1/+0
| | | | | | | Akaros support is unused, it was shutdown on syzbot for a while, the akaros development seems to be frozen for years as well. We have a bunch of hacks for Akaros since it supported only super old gcc and haven't supported Go. Remove it.
* all: use errors.As instead of .(type)Taras Madan2023-07-241-2/+3
|
* all: use special placeholder for errorsTaras Madan2023-07-241-2/+2
|
* pkg/build: added build configs for androidLiz Prucka2023-03-241-0/+2
| | | | | | | | Added config structure in build/Android to allow specifying specific Android targets. Build config is optional and extensible for individual build instances.
* pkg/build: add build code for Android devicesKris Alder2023-03-081-0/+2
| | | | | | | | | Booting physical Android devices requires building a few artifacts, as described at https://source.android.com/docs/setup/build/building-kernels. When a ProxyVM type is used, we need to differentiate whether or not to use the Android build logic, so we add an additional mapping which uses a different name but the same VM logic.
* pkg/build: rename android.go to cuttlefish.goKris Alder2023-02-131-1/+1
| | | | | | Building images for physical Android devices has different logic and options and should be in separate files. This makes it less ambiguous and frees up android.go for Android device code.
* pkg/build: be more lenient when parsing Bazel's build logTobias Werth2022-10-281-1/+1
| | | | | | | When Bazel is released with https://github.com/bazelbuild/bazel/commit/c9f9b0b84c486 the message on build failures changes. In general, we advise not to read the output but use the build protocol instead.
* all: add support for custom linkerAleksandr Nogikh2022-10-121-7/+9
| | | | | Add this as an option to syz-ci and syz-build tools. Otherwise we cannot use clang + ld.lld for kernel builds.
* pkg/build: extract fuchsia build errors betterDmitry Vyukov2022-09-131-1/+2
|
* pkg/build: support debug tracingDmitry Vyukov2022-06-241-0/+5
| | | | | | Add ability to trace build process and save debug artefacts. Add tracing of ELF signature calculation. Useful for debugging of #2297.
* pkg/build: return error on errorDmitry Vyukov2022-06-241-1/+2
| | | | Currenlty we shadow err variable and return nil if found no builder.
* pkg/build: build Android kernel and embed in Cuttlefish imageKris Alder2022-05-061-2/+6
| | | | | | | | | Android uses some config files (specified with the BUILD_CONFIG environment variable) to configure kernel builds. KASan configurations already exist. We want to mount the image, install a new Cuttlefish emulator binary (using fetch_cvd) and copy over the kernel that we've built.
* pkg/build: simplify the codeAleksandr Nogikh2022-04-081-29/+14
| | | | | | | With very few exceptions, the building code remains essentially the same, so there's no need to explicity specify all possible combinations. Refactor the code.
* pkg/build: increse timeout for bazelDmitry Vyukov2021-09-211-3/+4
| | | | | | | | | We've just got a timeout failure for TestCompilerIdentity test: --- FAIL: TestCompilerIdentity (0.00s) --- FAIL: TestCompilerIdentity/bazel (60.19s) build_test.go:24: failed: timedout ["bazel" ""] FAIL
* all: try to query compiler id even when a build failsAleksandr Nogikh2021-09-161-6/+8
| | | | | | | | Currently syzkaller leaves an empty CompilerID, when it has failed to build a kernel. However, in almost all cases this is possible to do. Query compiler information irregardless of whether the build process is successful.
* pkg/build: modify builder interfaceAleksandr Nogikh2021-07-201-12/+2
| | | | | | | | | Modify the `builder` interface in such a way that build method also returns a struct containing extra information about the build process. This allows to fetch compiler ID from individual builders. Also, this makes the `signer` interface obsolete, as this information can also go into that structure.
* all: capture compiler id during the build processAleksandr Nogikh2021-07-201-15/+31
| | | | | | | | | Default compilers are specified in the OS- and platform-dependent logic. It is more convenient to extract info about them during the kernel build itself, rather than during the manager object initialization. Apply the necessary changes throughout the code that is involved in building the kernels and processing information about this process.
* all: remove pointers to pkg.build.ParamsAleksandr Nogikh2021-07-201-3/+3
| | | | | | | | | | The struct pkg.build.Params is currently primarily passed on as a pointer, which leads make it hard to see the places, where it can (and should) actually be modified. Make it all more explicit by only passing pointer references to objects of this type when the object is expected to be modified by the function. In fact, at this moment there are no such situations.
* pkg/build: recognize make's "No rule to make target" errorDmitry Vyukov2021-06-151-0/+1

* pkg/build: extract another build error root causeDmitry Vyukov2021-01-051-12/+13
|
* sys/targets: add OS/Arch name constsDmitry Vyukov2020-10-261-12/+13
| | | | | | | | | | | | We use strings to identify OS/Arch. These strings are duplicated throughout the code base massively. golangci-lint points to possiblity of typos and duplication. We already had to define these names in pkg/csource and disable checking for prog package. A future change triggers such warnings in another package. Add OS/Arch name consts to sys/targets so that they can be used to refer to OS/Arch. Use the consts everywhere.
* pkg/build: detect errors due to missing filesDmitry Vyukov2020-10-211-0/+1

* pkg/bisect: add ccache optionJouni Hogander2020-09-211-0/+1
| | | | | | Add option to use ccache in kernel builds. Signed-off-by: Jouni Hogander <jouni.hoegander@partner.bmw.de>
* pkg/build: support Linux s390xAlexander Egorenkov2020-09-091-0/+1
| | | | Signed-off-by: Alexander Egorenkov <Alexander.Egorenkov@ibm.com>
* pkg: get and store Maintainers dataPedro Lopes2020-07-311-5/+6
| | | | | | Create a struct on pkg/vcs to store data of syzkaller email recipients and update its users. The struct contains default name, email, and a label to divide user into To and Cc when sending the emails.
* pkg/build: extract "multiple definition" linker errorsDmitry Vyukov2020-06-141-5/+17
|
* pkg/build: chmod output ssh keyDmitry Vyukov2020-05-291-0/+6
| | | | | ssh is very picky about ssh key permissions. Let's enforce the right persmissions without bothering user with this.
* pkg/build: find maintainers for build errorsDmitry Vyukov2020-05-091-11/+60
| | | | | | | Extract build error source file and obtain maintainers so that we can mail the report to the right people. Update #1667
* pkg/build: improve extraction of build errorsDmitry Vyukov2019-12-111-11/+33
| | | | | | | | | 1. Extract multiple error lines (up to 10). Gives more complete picture, maybe the first one is not the most indicative one. 2. Replace weird unicode quotes with normal quotes. These may be mishandled by some systems that don't understand utf-8.
* pkg/build: add build signaturesDmitry Vyukov2019-11-061-5/+24
| | | | | | | Add optional build signature for images, currently only implemented for linux. This can be used in bisection process to detect changes that does not affect kernel. Update #1271
* pkg/build: refactor Image function argumentsDmitry Vyukov2019-11-061-14/+26
| | | | | | | Image takes too many arguments, so we need to do lots of forwarding, adding new argumnets is painful and most OSes are not interested in lots of arguments. Combine all arguments into a params struct.
* pkg/vcs: make EnvForCommit return full compiler pathDmitry Vyukov2019-10-221-1/+1
| | | | | | | All callers of EnvForCommit need the compiler path, so move this logic into EnvForCommit to avoid duplication. Also simplifies tests because test impl can now return an empty compiler (which should be unused).
* pkg/bisect: add initial testing support for cause bisectionZubin Mithra2019-10-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | (note: incomplete change) Refactor existing code as follows: * Move reusable test utility functions from git_repo_test.go to pkg/vcs/test_util.go and make them exported. * Split Run() into Run()+runImpl(). * Change type of bisect.go:env.inst to `instance.BuilderTester`. Change usage inside syz-testbuild/testbuild.go accordingly. * Move most of linux.PreviousReleaseTags() into vcs/git.go as git.previousReleaseTags(). * Allow build.CompilerIdentity to be mocked. Introduce the following changes: * instance.BuilderTester is an interface with methods BuildSyzkaller() BuildKernel() Test() NewEnv() now returns this interface. * type testEnv implements instance.BuilderTester. * type testBuilder implements builder interface. Add a entry into table inside pkg/build/build.go:getBuilder() to return testBuilder object.
* pkg/build: Add ppc64le Linux as a supported configurationAndrew Donnellan2019-05-031-0/+1
| | | | | | | | | | | Enable the Linux builder for ppc64le. For ppc64le, we use zImage rather than bzImage as our kernel target. Pass through the target architecture to buildKernel() so we can pick the right target based on arch. Closes: #1084 ("pkg/build: Support building Linux on ppc64le") Signed-off-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com>
* pkg/build: detect "Permission denied" as build errorDmitry Vyukov2019-04-091-0/+1
| | | | This happens when compiler has bad permissions.
* pkg/build: extract first build error instead of lastDmitry Vyukov2019-04-051-1/+4
| | | | | The first error is usually more informative and significant. Extract first error instead of last.
