memory corruption with udhcpc

[Thomas Andrews]

Hi,

I've made the following addition to networking/udhcp/options.c

    {"staticrte",   OPTION_IP_PAIR | OPTION_LIST | OPTION_REQ, 0x021},

When I get the DHCP server to supply one IP:gateway pair there is no
problem, but when I supply two pairs I get the following error:

    *** glibc detected *** malloc(): memory corruption: 0x0806ee48 ***

0x21 is DHCP option 33 which is "static routes", and is expected to look
something like this: host-ip, gateway-ip eg:

    10.5.5.1, 10.1.1.1

I am using dnsmasq as the DHCP server, and I can see that the packets
are correctly formatted using ethereal. (In both cases.)

If I use OPTION_IP instead of OPTION_IP_PAIR, I do not have any problems
at all, no matter whether I have a single pair or more.

What can be the problem here ?

FYI this line is added to dnsmasq.conf to get dnsmasq to supply routes:

    dhcp-option=33,10.5.5.1,10.1.1.1,10.5.5.2,10.11.11.1

Many thanks,
Thomas
