[Dnsmasq-discuss] server option interface name don't work

[MURASE Katsunori]

Hello.

I am using dnsmasq 2.47.
"server" option with *long* interface name don't work.

This is my configuration file.
    server=/example.jp/10.0.0.1 at eth10

Dnsmasq say following message.
    dnsmasq: ignoring nameserver 10.0.0.1 - cannot make/bind socket: No such device

My patch. Replase to strlen from sizeof.

diff -ruNp org/dnsmasq-2.47/src/network.c dnsmasq-2.47/src/network.c

Thanks.
