getsockopt failed strangely: invalid argument
As an update, someone suggested that there might be an issue with EABI vs. OABI on the ARM platform, so I reconfigured iptables with --enable-static and --disable-dynamic, since I think that there is not an issue as long as iptables doesn't try to build linking to the EABI-built kernel libraries. After rebuilding, I tried to run "iptables -L" again and this time received a different error:
"getsockopt failed strangely: invalid argument"
As before, if anyone has any suggestions on how I might resolve this error to get iptables working, I'd be very appreciative.
