Subject: Segmentation fault in loading snat_plugin.so
Hi all,
Thanks for time.
I have adjusted snat nodes like below, then i got segmentation fault.
It seems that when node snat-det-out2in is registering himself, there is no
node snat-out2in.
But node snat-out2in was already registered before that, why ?
VLIB_NODE_FUNCTION_MULTIARCH (snat_out2in_fast_node, snat_out2in_fast_node_fn);
VLIB_REGISTER_NODE (snat_det_out2in_node) = {
.function = snat_det_out2in_node_fn,
.name = "snat-det-out2in",
.vector_size = sizeof (u32),
.format_trace = format_snat_out2in_trace,
.type = VLIB_NODE_TYPE_INTERNAL,
.n_errors = ARRAY_LEN(snat_out2in_error_strings),
.error_strings = snat_out2in_error_strings,
.runtime_data_bytes = sizeof (snat_runtime_t),
.n_next_nodes = 3,
/* edit / add dispositions here */
.next_nodes = {
[SNAT_OUT2IN_NEXT_DROP] = "error-drop",
[SNAT_OUT2IN_NEXT_LOOKUP] = "ip4-lookup",
[SNAT_OUT2IN_NEXT_SLOW_PATH] = "snat-out2in",
},
};
VLIB_NODE_FUNCTION_MULTIARCH (snat_det_out2in_node, snat_det_out2in_node_fn);
VLIB_REGISTER_NODE (snat_out2in_node) = {
.function = snat_out2in_node_fn,
.name = "snat-out2in",
.vector_size = sizeof (u32),
.format_trace = format_snat_out2in_trace,
.type = VLIB_NODE_TYPE_INTERNAL,
.n_errors = ARRAY_LEN(snat_out2in_error_strings),
.error_strings = snat_out2in_error_strings,
.runtime_data_bytes = sizeof (snat_runtime_t),
.n_next_nodes = 3,
/* edit / add dispositions here */
.next_nodes = {
[SNAT_OUT2IN_NEXT_DROP] = "error-drop",
[SNAT_OUT2IN_NEXT_LOOKUP] = "ip4-lookup",
[SNAT_OUT2IN_NEXT_ICMP_ERROR] = "ip4-icmp-error",
},
};
