Chris Richardson updated DISPATCH-40:
-------------------------------------
Description:
Using the following configuration on two nodes (designated "client" and
"server"), the client will segfault while connecting the server:
{code}
# Server config
container {
worker-threads: 4
container-name: Qpid.Dispatch.Router.Server
}
ssl-profile {
name: ssl-profile-name
}
listener {
addr: 0.0.0.0
port: amqp
sasl-mechanisms: ANONYMOUS
}
listener {
role: inter-router
addr: 0.0.0.0
port: 20000
sasl-mechanisms: ANONYMOUS
}
router {
mode: interior
router-id: Router.Server
}
{code}
{code}
# Client config
container {
worker-threads: 4
container-name: Qpid.Dispatch.Router.A
}
ssl-profile {
name: ssl-profile-name
}
listener {
addr: 0.0.0.0
port: amqp
sasl-mechanisms: ANONYMOUS
}
connector {
role: inter-router
addr: 192.168.0.12 # Address of server node
port: 20000
sasl-mechanisms: ANONYMOUS
}
router {
mode: standalone
router-id: Router.A
}
{code}
Note the the client router mode is standalone. Changing this to "interior"
fixes the problem.
The segfault takes place at router_node.c:70,
{code}
DEQ_INSERT_TAIL(*ref_list, ref);
{code}
and is caused by the attempt to dereference the "ref_list" pointer, which
appears to be uninitialised or dangling.
The router mode "standalone" may be invalid in this configuration (?), the
process should not segfault!

The segfault takes place at router_node.c:70,
{code}
DEQ_INSERT_TAIL(*ref_list, ref);
{code}
and is caused by the attempt to de-reference the "ref_list" variable, which
appears to be uninitialised or dangling.
The router mode "standalone" may be invalid in this configuration (?), the
process should not segfault!
