As a bonus, we "learn" the local/remote RTS from the S1GW, which can be used in new PFCP related testcases.

[M] Change in osmo-ttcn3-hacks[master]: s1gw: add testcases for impatient eNB during MME pool selection
by fixeria 18 Mar '26

18 Mar '26

fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/42359?usp=email ) Change subject: s1gw: add testcases for impatient eNB during MME pool selection ...................................................................... s1gw: add testcases for impatient eNB during MME pool selection Two new test cases covering scenarios where the eNB disconnects before S1 setup completes, targeting specific states of the enb_proxy FSM: * TC_mme_pool_enb_disc_wait_s1setup_req: eNB connects but disconnects before sending S1SetupReq (enb_proxy in wait_s1setup_req). No MME connection is ever attempted; S1GW must handle the disconnect cleanly. * TC_mme_pool_enb_disc_wait_s1setup_rsp: eNB sends S1SetupReq, S1GW forwards it to the first pool MME (enb_proxy in wait_s1setup_rsp), then eNB disconnects before the response arrives. S1GW must detect the eNB disconnect and close the open MME connection in response. A new helper S1GW_ConnHdlr.f_ConnHdlr_s1ap_close() is added for these tests: unlike f_ConnHdlr_s1ap_disconnect(), it closes the eNB-side socket without waiting for an S1APSRV_EVENT_CONN_DOWN from a pool server (since in these scenarios either no MME connection exists yet, or the CONN_DOWN is captured by the test body directly).

[L] Change in osmo-ttcn3-hacks[master]: s1gw: initial testcases for MME pooling
by fixeria 18 Mar '26

18 Mar '26

fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/42358?usp=email ) Change subject: s1gw: initial testcases for MME pooling ...................................................................... s1gw: initial testcases for MME pooling Three test cases covering the MME pool selection logic in OsmoS1GW: * TC_mme_pool_reject_fallback: S1GW falls back to the next pool entry when the first MME rejects S1SetupReq with S1SetupFailure. * TC_mme_pool_timeout_fallback: S1GW falls back when the first MME does not respond to S1SetupReq within the timeout. * TC_mme_pool_all_reject: all pool entries reject S1SetupReq; S1GW must send S1SetupFailure to the eNB and tear down the connection. Infrastructure added to support these tests: * S1AP_Server.ttcn: S1AP_ServerList type; directed register/unregister helpers (f_ConnHdlr_s1ap_register_to / _unregister_from) for use when multiple S1AP_Server_CT instances are active simultaneously. * S1GW_ConnHdlr.ttcn: f_ConnHdlr_s1ap_setup_pool() drives the pool setup sequence: pre-registers with all servers, sends S1SetupReq once (S1GW re-transmits it per-MME), then iterates through the expected behaviors (ACCEPT / REJECT / TIMEOUT) waiting for each server in turn. * S1GW_Tests.ttcn: f_init_s1ap_srv(N) starts N MME emulators on consecutive IP addresses; f_TC_exec_pool() orchestrates pool tests. * osmo-s1gw.config: a 'mme_pool' section with three entries is added alongside the existing sctp_client section. Older OsmoS1GW (without pooling support) will use sctp_client to connect to a single MME and the pool test cases will simply fail, as expected. Newer OsmoS1GW will use mme_pool and all three test cases will pass.

[M] Change in osmo-ttcn3-hacks[master]: s1gw: add tests for MME registry REST procedures
by fixeria 18 Mar '26

18 Mar '26

fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/42360?usp=email ) Change subject: s1gw: add tests for MME registry REST procedures ...................................................................... s1gw: add tests for MME registry REST procedures Add three test cases exercising the S1GW REST interface for MME pool management. The REST TCs are gated on the mp_rest_enable module parameter in the control block. TC_rest_mme_list: query the MME pool list via REST and verify it matches the three static entries from the 'mme_pool' section in osmo-s1gw.config (mme0/mme1/mme2 with their respective addresses). TC_rest_mme_add_del: add a new MME entry at runtime via REST, verify it appears in both the list and individual GET responses, then delete it and confirm it is gone. TC_rest_mme_del_fallback: delete mme0 from the pool at runtime and verify that a connecting eNB is routed directly to mme1, skipping the deleted entry. The pool is restored to its original state afterwards via f_REST_mme_pool_restore(). Also add: * {ts,tr}_MmeItem templates to S1GW_REST_Types.ttcn * f_REST_mme_find(): returns the integer index of a named entry in a MmeList, or -1 if not found; used for both presence and absence checks * f_REST_mme_pool_restore(): deletes all current entries and re-adds mme0/mme1/mme2 in original order to keep pool state predictable across test cases Change-Id: I260bc987ab8ae0ecb547d0b69b261fd97c5c9c23 Related: SYS#7052 --- M s1gw/S1GW_REST_Types.ttcn M s1gw/S1GW_Tests.ttcn M s1gw/expected-results.xml 3 files changed, 199 insertions(+), 1 deletion(-) Approvals: osmith: Looks good to me, but someone else must approve pespin: Looks good to me, but someone else must approve fixeria: Looks good to me, approved Jenkins Builder: Verified diff --git a/s1gw/S1GW_REST_Types.ttcn b/s1gw/S1GW_REST_Types.ttcn index f182ae9..696df3d 100644 --- a/s1gw/S1GW_REST_Types.ttcn +++ b/s1gw/S1GW_REST_Types.ttcn @@ -157,4 +157,30 @@ external function dec_ErabItem(in octetstring data) return ErabItem with { extension "prototype(convert) decode(JSON)" } + +template (value) MmeItem +ts_MmeItem(template (value) charstring name, + template (value) charstring raddr, + template (omit) charstring laddr := omit, + template (omit) Port rport := omit, + template (omit) TacList tac_list := omit) := { + name := name, + laddr := laddr, + raddr := raddr, + rport := rport, + tac_list := tac_list +} +template (present) MmeItem +tr_MmeItem(template (present) charstring name := ?, + template (present) charstring raddr := ?, + template charstring laddr := *, + template Port rport := *, + template TacList tac_list := *) := { + name := name, + laddr := laddr, + raddr := raddr, + rport := rport, + tac_list := tac_list +} + } with { encode "JSON" } diff --git a/s1gw/S1GW_Tests.ttcn b/s1gw/S1GW_Tests.ttcn index d870be8..f522406 100644 --- a/s1gw/S1GW_Tests.ttcn +++ b/s1gw/S1GW_Tests.ttcn @@ -1200,6 +1200,168 @@ { S1APSRV_SETUP_ACCEPT });
