* docs: add KFuzzTest documentationEthan Graham2025-09-222-0/+255
| | | | | | | Add documentation for syzkaller's KFuzzTest integration, and a separate documentation file for the syz-kfuzztest program. Signed-off-by: Ethan Graham <ethangraham@google.com>
* kfuzztest: introduce syz_kfuzztest_run pseudo-syscallEthan Graham2025-09-221-0/+1
| | | | | | | | | | | | | Add syz_kfuzztest_run pseudo-syscall, KFuzzTest attribute, and encoding logic. KFuzzTest targets, which are invoked in the executor with the new syz_kfuzztest_run pseudo-syscall, require specialized encoding. To differentiate KFuzzTest calls from standard syzkaller calls, we introduce a new attribute called KFuzzTest or "kfuzz_test" in syzkaller descriptions that can be used to annotate calls.

* prog: pkg/compiler: docs: introduce the `no_squash` attributeAlexander Potapenko2025-09-091-0/+3
| | | | | | | | | | | | | | | | | The `no_squash` per-syscall attribute prevents the fuzzer from generating squashed arguments to a particular syscall. This is particularly helpful for pseudo-syscalls with elaborate arguments that are hard to reason about when they are squashed - e.g. for syz_kvm_add_vcpu() that takes a SYZOS program as an input. I've considered an alternative solution that prohibits ANY for all pseudo-syscalls. But there is a bunch of existing programs (both the tests and the repros) for syscalls like syz_mount_image() for which the benefit of not passing ANY is not immediately obvious. I therefore decided to go with an explicit attribute that can later be enforced for every pseudo-syscall at compile time.

* prog: annotate image assets with fsck logsFlorent Revest2024-12-091-1/+4
| | | | | | | | | | | | | | | | | | Syscall attributes are extended with a fsck command field which lets file system mount definitions specify a fsck-like command to run. This is required because all file systems have a custom fsck command invokation style. When uploading a compressed image asset to the dashboard, syz-manager also runs the fsck command and logs its output over the dashapi. The dashboard logs these fsck logs into the database. This has been requested by fs maintainer Ted Tso who would like to quickly understand whether a filesystem is corrupted or not before looking at a reproducer in more details. Ultimately, this could be used as an early triage sign to determine whether a bug is obviously critical.
* tools/syz-env: add local build optionStefan Wiehler2024-11-291-0/+6
| | | | Useful for testing local Dockerfile changes that have not been pushed yet.
* docs: update reproduction instructionsAleksandr Nogikh2024-11-299-92/+84
| | | | | | | 1. Get rid of executing_syzkaller_programs.md as it now mostly overlaps with reproducing_crashes.md. 2. Update the instructions on building the kernel with syzbot compilers. 3. Update the links throughout the documentation.
* docs: rewrite reproducing_crashes.mdAleksandr Nogikh2024-11-251-25/+169
| | | | | | | | | | Let's list all the possible ways of reproducing syzkaller crashes locally and keep the instructions of how to manually craft a reproducer at the bottom. Add information about the ktest tooling - now it also automates the reproduction of syzbot bugs. See the discussion at: https://groups.google.com/g/syzkaller/c/UTPrWcJfS8Q/m/K1YXz-f1AQAJ

* dashboard: allow multiple allowed authentication domainsFlorent Revest2024-10-101-1/+1
| | | | | | | In some situations, it could be useful to share access to the dashboard to multiple authentication domains. The current GlobalConfig format doesn't really allow it so this deprecates the existing field and add a new slice of allowed authentication domains.

* all: add npm package to syz-envJoey Jiao2024-08-291-0/+13
| | | | | | | | | | act(https://github.com/nektos/act) is used to build github workflow locally. When running `act -j build` in local host, it reports: exec failed: unable to start container process: exec: "node": executable file not found in $PATH: unknown. Adding nodejs package can fix the build error. Updated docs with act usage too.
