Zach Riggle 0eca949a6c RFC: android: Add support for untrusted_app sandboxing (#697) 
executor: add support for android_untrusted_app sandbox

This adds a new sandbox type, 'android_untrusted_app', which restricts
syz-executor to the privileges which are available to third-party applications,
e.g. those installed from the Google Play store.

In particular, this uses the UID space reserved for applications (instead of
the 'setuid' sandbox, which uses the traditional 'nobody' user / 65534)
as well as a set of groups which the Android-specific kernels are aware of,
and finally ensures that the SELinux context is set appropriately.

Dependencies on libselinux are avoided by manually implementing the few
functions that are needed to change the context of the current process,
and arbitrary files.  The underlying mechanisms are relatively simple.

Fixes google/syzkaller#643

syzkaller - kernel fuzzer

Build Status Go Report Card License

syzkaller is an unsupervised coverage-guided kernel fuzzer. Linux kernel fuzzing has the most support, akaros, freebsd, fuchsia, netbsd, windows and gvisor are supported to varying degrees.

The project mailing list is syzkaller@googlegroups.com. You can subscribe to it with a google account or by sending an email to syzkaller+subscribe@googlegroups.com.

List of found bugs.

Documentation

Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Most of the documentation at this moment is related to the Linux kernel. For other OS kernels check: Akaros, FreeBSD, Fuchsia, NetBSD, Windows, gVisor.
