Hi all,
When I create a GRE tunnel using the API, and then try to look at an API
trace to see exactly how it was added, the gre_tunnel_add_del message
requesting the tunnel creation does not show up in the output. Neither do
subsequent gre_tunnel_dump messages. The tunnels are successfully created
and when I send a gre_tunnel_dump I receive a gre_tunnel_details, so I know
the messages are being received and processed.
I'm retrieving the trace by running:
vppctl api trace save foo
vppctl api trace dump /tmp/foo
The build I'm seeing this on is from a copy of master from wednesday. This
is the last commit:
fd77f8c00 quic: remove cmake --target
I poked around and tracked this down to api_global_main.api_trace_cfg
having trace_enable set to 0 on the entries for the GRE messages:
(gdb) p api_global_main.msg_names[1253]
$23 = 0x7f95985ed677 "gre_tunnel_add_del"
(gdb) p api_global_main.api_trace_cfg[1253]
$24 = {size = 0, trace_enable = 0, replay_enable = 0}
(gdb) p api_global_main.msg_names[1255]
$27 = 0x7f95985ed6a3 "gre_tunnel_dump"
(gdb) p api_global_main.api_trace_cfg[1255]
$28 = {size = 0, trace_enable = 0, replay_enable = 0}
Are the GRE messages intentionally excluded from being traced? Or is this
an oversight?
Thanks!
-Matt
