[M] Change in libosmo-sccp[master]: ipa: Use ASP name as ipa_unit_name on dynamic ASPs
pespin has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sccp/+/35348?usp=email ) Change subject: ipa: Use ASP name as ipa_unit_name on dynamic ASPs .. ipa: Use ASP name as ipa_unit_name on dynamic ASPs A recent patch fixed a long problem where the ASP name (instead of expected AS name) was used as ipa_unit_name in IPA based ASPs. For server side it doesn't matter much, sense anyway the ipa_unit_name is actually restored on the struct with what's received in IPA GET_RESP message (see ipa_asp_fsm_wait_id_resp()). So the fix was actually for the client side in the scenario where a non-dynamic ASP with an assigned AS was configured in the VTY. However, dynamic ASPs usually have no assigned AS (because in general it is really not created/configured, as the ASP is created on the flight). As a result, the recent patch (see "Fixes" below), broke dynamic ASPs case because from then one ipa_asp_fsm_start() would fail and terminate the FSM because ipa_find_as_for_asp() was returning NULL. So improve the recent patch by applying the previous logic for dynamic ASPs: * On the server side, it really doesn't matter since as mentioned, the field will be repopulated later on, but allows the code to avoid terminating the FSM and hence be brought up and be ready to receive clients. * On the client case, this is how dynamic IPA ASPs were ment to be used when they were introduced anyway (use ASP as ipa_unit_id, meaning "AS name" == "ASP name"). Furthermore, on the client side, the non-dynamic IPA ASPs need their bring up be delayed until assigned to an AS, because the AS name is sent in ipa_unit_name field in Tx IPA ID RESP. This usually happens at a later point than ASP (FSM) creation, because first the ASP object is created (through VTY or API) and then assigned to an AS through osmo_ss7_as_add_asp() usually from a later "asp" vty command in the "as" node.

[M] Change in libosmo-sccp[master]: ipa: Use ASP name as ipa_unit_name on dynamic ASPs
Attention is currently required from: laforge, pespin. Hello Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-sccp/+/35348?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Code-Review-1 by pespin, Verified+1 by Jenkins Builder Change subject: ipa: Use ASP name as ipa_unit_name on dynamic ASPs .. ipa: Use ASP name as ipa_unit_name on dynamic ASPs A recent patch fixed a long problem where the ASP name (instead of expected AS name) was used as ipa_unit_name in IPA based ASPs. For server side it doesn't matter much, sense anyway the ipa_unit_name is actually restored on the struct with what's received in IPA GET_RESP message (see ipa_asp_fsm_wait_id_resp()). So the fix was actually for the client side in the scenario where a non-dynamic ASP with an assigned AS was configured in the VTY. However, dynamic ASPs usually have no assigned AS (because in general it is really not created/configured, as the ASP is created on the flight). As a result, the recent patch (see "Fixes" below), broke dynamic ASPs case because from then one ipa_asp_fsm_start() would fail and terminate the FSM because ipa_find_as_for_asp() was returning NULL. So improve the recent patch by applying the previous logic for dynamic ASPs: * On the server side, it really doesn't matter since as mentioned, the field will be repopulated later on, but allows the code to avoid terminating the FSM and hence be brought up and be ready to receive clients. * On the client case, this is how dynamic IPA ASPs were ment to be used when they were introduced anyway (use ASP as ipa_unit_id, meaning "AS name" == "ASP name").
