Comment (by jackburton):
I found out that the KDL doesn't happen if I remove the ipv6 module.
After having a look at the code, I suspect that the culprit is the
function
ipv6_setsockopt() in src/add-ons/kernel/network/protocols/ipv6.cpp
at line 1240 it calls sDatalinkModule->get_interface_with_address() but,
unlike the ipv4 equivalent code, it does not call
sDatalinkModule->put_interface(interface).
ipv6:
{{{
struct net_interface* interface
= sDatalinkModule->get_interface_with_address(
(sockaddr*)address);
if (interface == NULL) {
delete address;
return EADDRNOTAVAIL;
}
delete protocol->multicast_address;
protocol->multicast_address = (struct sockaddr*)address;
return B_OK;
}}}
cf. ipv4:
{{{
struct net_interface* interface
= sDatalinkModule->get_interface_with_address(
(sockaddr*)address);
if (interface == NULL) {
delete address;
return EADDRNOTAVAIL;
}
delete protocol->multicast_address;
protocol->multicast_address = (struct sockaddr*)address;
sDatalinkModule->put_interface(interface);
return B_OK;
}}}
I don't have a development system at hand, but maybe somebody can comment
on this, or even commit the fix.
