syzkaller config

[Christoph Paasch <cpaasch@apple.com>]

Hello,

this is my syzkaller config:

{
        "target": "linux/amd64",
        "http": "127.0.0.1:56741",
        "workdir": "/home/cpaasch/gopath/src/github.com/google/syzkaller/workdir_kasan_net",
        "kernel_obj": "/mnt/tmp/build/",
        "kernel_src": "/mnt/tmp/mptcp_syzkaller/",
        "kernel_build_src": "/mnt/tmp/mptcp_syzkaller/",
        "image": "/home/cpaasch/syzkaller/tools/stretch.img",
        "sshkey": "/home/cpaasch/syzkaller/tools/stretch.id_rsa",
        "syzkaller": "/home/cpaasch/gopath/src/github.com/google/syzkaller",
        "disable_syscalls": ["perf_event_open", "syz_mount_image", "syz_read_part_table", "openat$ttyprintk", "mount", "mkdir", "openat$ptmx", "mq_open", "fsetxattr", "rt_tgsigqueueinfo", "ioctl$VT_RESIZE", "ioctl$TIOCVHANGUP", "get_robust_list", "openat$nullb", "ioctl$SCSI_IOCTL_SEND_COMMAND", "lremovexattr", "mknod$loop", "write$binfmt_script", "syz_open_dev$sg", "write$nbd", "prlimit64", "write$P9_RRENAMEAT", "fcntl$addseals", "finit_module", "ioctl$KDSETMODE", "write$FUSE_NOTIFY_STORE", "ioctl$TIOCL_SETVESABLANK", "fsmount", "socket$vsock_stream", "socketpair$unix", "socket$nl_audit", "connect$unix", "bind$unix"],
        "procs": 8,
        "type": "qemu",
        "vm": {
                "count": 24,
                "kernel": "/mnt/tmp/build/arch/x86/boot/bzImage",
                "cpu": 2,
                "mem": 4096
        }
}





The way I generate this list of disabled syscals is simply over time, when I
saw that syzkaller was spending all of its efforts in those syscalls, I
added it to the disable-list. That way now it is spending more time in
MPTCP/networking related code.
