[S] Change in osmo-sgsn[master]: Announce SGSN own TEID during UpdatePDPCtxReq after UE goes PMM-IDLE
by pespin 31 Jul '24

31 Jul '24

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-sgsn/+/37644?usp=email ) Change subject: Announce SGSN own TEID during UpdatePDPCtxReq after UE goes PMM-IDLE ...................................................................... Announce SGSN own TEID during UpdatePDPCtxReq after UE goes PMM-IDLE When the UE/RNC closes the Iu conn (while keeping the PDP Context activated), the SGSN updates the GGSN to point the GTPU tunnel to itself. Unfortunately, only the IP address was being updated while the TEID was kept the same (the one from the RNC). As a result, when new MT data arrived at the GGSN, it would forward it over GTPU to the SGSN using the incorrect RNC TEID, which the libgtp stack at osmo-sgsn would silently drop due to not being known (because it was >PDP_MAX=1024). The issue can be triggered in test SGSN_Tests_Iu.TC_pmm_idle_rx_mt_data.
