[M] Change in osmo-ttcn3-hacks[master]: GTPv2_Emulation: improve accessibility of unit-data (TEID0)
by laforge 04 Sep '23

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/34286?usp=email ) Change subject: GTPv2_Emulation: improve accessibility of unit-data (TEID0) ...................................................................... GTPv2_Emulation: improve accessibility of unit-data (TEID0) When GTPv2 unit-data is passed around, there is always the problem that it is routed to the MTC_CT (TEID0). The reason for this is that GTPv2_Emulation cannot determine a specific receiver component because unit-data does not contain any addressing fields that would identifiy a specific vc_conn. In GTPv2_Emulation there is already a mechanism implemented that detects responses by their sequence number. Untfortunately this does only work when the vc_conn has send a unit-data message before so that the sequence number of the response can be guessed. In case the first messages comes from the IUT, there is no way to determine the receiving vc_conn, so this message is then routed to the MCT_CT (TEID0). This can be a problem for testcases that run from inside a ConnHdlr componet. The solution that is proposed in this patch uses a mechanism that allows to create an expectation for a specific messageType. When the GTPv2_Emulation sees a unit-data message with the expected messageType, it will forward it to all ConnHdlr (vc_conn) components that have registered for this messageType previously.

[S] Change in osmo-ttcn3-hacks[master]: GTPv2_Emulation: make sure g_uecups_conn_id is populated.
by laforge 04 Sep '23

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/34265?usp=email ) Change subject: GTPv2_Emulation: make sure g_uecups_conn_id is populated. ...................................................................... GTPv2_Emulation: make sure g_uecups_conn_id is populated. In function f_init, we activate altstep as_uecups_ind at the end of the function. In as_uecups we use the template generator function tr_UECUPS_RecvFrom_R(). In this function we use g_uecups_conn_id, which is only populated when use_gtpu_daemon is set to true. When use_gtpu_daemon is false g_uecups_conn_id will be <unbound>, which leads into an error.
