double fault trap at ipsp_spd_lookup, expected iked triggered

Brad DeMorrow-3
>Synopsis: double fault trap at ipsp_spd_lookup, expected iked triggered
>Category: kernel
>Environment:
        System      : OpenBSD 6.4
        Details     : OpenBSD 6.4 (GENERIC.MP) #8: Thu Mar 21 14:26:24 CET 2019
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64
>Description:
        I was connecting to iked over the internet with my phone repeatedly
        in order to test it out.  Suddenly the host stopped responding and
        I found it had crashed.
       
        I keep a serial cable hooked up to it, so I was able to get a good
        trace.
>How-To-Repeat:
        Configure iked as follows:
        >>>iked.conf
ikev2 "Road Warrior - PSK" passive ipcomp esp \
        from 0.0.0.0/0 to 10.0.1.0/24 \
        from 10.0.0.0/24 to 10.0.1.0/24 \
        local egress peer any \
        srcid "host.domain.com" \
        psk "shared_secret" \
        config protected-subnet 0.0.0.0/0 \
        config address 10.0.1.0/24 \
        config netmask 255.255.255.0 \
        config dhcp-server 10.200.0.1 \
        config name-server 10.200.0.1 \
        tag "IKED" \
        tap enc0

        Repeatedly connect and disconnect from iked until it crashes.

       

>Fix:
        Honestly I just disable iked for the time being.
