[Android]unknown field 'vmlinux' in config

[$rik@nth]

Hi Dmitry,

Yesterday i switched to tip of syzkaller to try some new changes. The config which i am using is been tried on tip and getting error. Is something wrong? or changed the config parameters?

2018/08/08 10:28:01 unknown field 'vmlinux' in config

My config looks like this

{
    "cover": true,
     "http": "localhost:50001",
      "ignores": [
       "DEBUG:*",
        "INFO:*",
        "ODEBUG: object is on stack, but not annotated",
        "WARNING:.*",
        "KASAN: slab-out-of-bounds in dsi_link_lp_clk_start",
        "KASAN: double-free or invalid-free in*.*"
    ],
    "Kernel_Src": "$HOME/kernel/msm-4.9",
    "procs": 8,
    "sandbox": "none",
    "reproduce": true,
    "syzkaller": "$HOME/syzkaller_08082018/src/github.com/google/syzkaller",
    "target": "linux/arm64",
    "type": "adb",
    "vm": {
        "devices": [
            "a443jk3"
        ]
    },
    "vmlinux": "$HOME/Kernel/obj/KERNEL_OBJ/vmlinux",
    "workdir": "$HOME/syzkaller.7.8_2.0_06222018"
}

Yes, it was deprecated a while ago with a warning message, then
removed, docs are updated.

https://github.com/google/syzkaller/blob/12c7428ad27a7abbcb1dbf342af448021e8cd372/docs/linux/setup_ubuntu-host_android-device_arm32-kernel.md this is still having the vmlinux entry in the example config. 

How syzkaller will point to the vmlinux if relative path is not provided in the config?

You are looking at the old version of the doc. The old fixed version
will stay as it is forever. Look at HEAD.
