Package: dnsmasq

Severity: serious

I've got this nasty bugs, when I connect using my nokia n97
dnsmasq crashes, after a lot of trials/debugs
I've found that the place where it crashes is only a side effect
even if the code looks a bit 'obscure':
645. if (config)
646. {
647. struct dhcp_netid_list *list;
648.
649. for (list = config->netid; list; list = list->next)
650. {
651.> list->list->next = netid;
652. netid = list->list;
653. }
654. }
src/rfc2131.c
list->list->next seems to be bogus but looks like it's a circular list
the bt:
0x08065aed in dhcp_reply (context=0x807fbc0, iface_name=0xbffff39c "eth0",
int_index=2, sz=300, now=1275819570, unicast_dest=0, is_inform=0xbffff360,
pxe=0) a
t rfc2131.c:651
(gdb) bt

(gdb) p list->list
$6 = (struct dhcp_netid *) 0x57e58955
(gdb) p list->list->next
Cannot access memory at address 0x57e58959
anyway disabling i18n the problem does not happens,
looks like canonicalise() in utils.c has something to do with the problem
the linked list code was added in 2.53
