syzkaller is an unsupervised coverage-guided kernel fuzzer

Update descriptions to be compatible with latest linux-next (next-20190715), which in theory will match v5.3-rc1 when the merge window closes. - KEYCTL_GRANT_PERMISSION was reverted. So remove its description. - CRYPTO_ALG_TYPE_DIGEST was removed. So remove its description. - IB_QP_CREATE_SIGNATURE_EN was renamed to IB_QP_CREATE_INTEGRITY_EN. Also remove the sys/linux/rdma_*.const files which were incorrectly checked into git. The real copies of those files are in sys/linux/dev_infiniband_rdma_*.const. For now I did *not* check for other new APIs that need to be described. |

syzkaller is an unsupervised coverage-guided kernel fuzzer.
Supported OSes: Akaros, FreeBSD, Fuchsia, gVisor, Linux, NetBSD, OpenBSD, Windows.
Mailing list: syzkaller@googlegroups.com (join on web or by email).
Found bugs: Akaros, Darwin/XNU, FreeBSD, Linux, NetBSD, OpenBSD, Windows.
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, Darwin/XNU, FreeBSD, Fuchsia, NetBSD, OpenBSD, Windows, gVisor.
