dvyukov sys: check that target consts are defined
Currently when we get target consts with target.ConstMap["name"]
during target initialization, we just get 0 for missing consts.
This is error-prone as we can mis-type a const, or a const may
be undefined only on some archs (as we have common unix code
shared between several OSes).
Check that all the consts are actually defined.
The check detects several violations, to fix them:
1. move mremap to linux as it's only defined on linux
2. move S_IFMT to openbsd, as it's only defined and used on openbsd
3. define missing MAP_ANONYMOUS for freebsd and netbsd
4. fix extract for netbsd

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.

List of found bugs.


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, OpenBSD, Windows, gVisor.
