[M] Change in osmo-pcu[master]: Fix DL_TBF PACCH ass done on UL_TBF already scheduled to tx last PKT ...

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-pcu/+/32339 ) Change subject: Fix DL_TBF PACCH ass done on UL_TBF already scheduled to tx last PKT CTRL ACK ...................................................................... Fix DL_TBF PACCH ass done on UL_TBF already scheduled to tx last PKT CTRL ACK Dispatching TBF_EV_CONTENTION_RESOLUTION_MS_SUCCESS means the UL TBF is able to be used to assign DL TBFs over PACCH. However, there's an extra implicit restriction: if the PCU already sent the final UL ACK/NACK to that UL TBF, then whatever message sent after it cannot be reliably answered, since the MS will go back to idle state after issues the PKT CTRL ACK for that final UL ACK/NACK. This condition is already being checked in contention_resolution_success(): """ if (ms_need_dl_tbf(ms()) && !tbf_ul_ack_waiting_cnf_final_ack(this)) ms_new_dl_tbf_assigned_on_pacch(ms(), this); """ Since we are considering the UL TBF to have done contention resolution when we transmit the *first* UL ACK/NACK, it mans we are doing both things on the same code path iif the *first* UL ACK/NACK is at the same time the *final* UL ACK for that UL TBF. This can happen if the UL TBF is only sending 1 block, which will have CV=0. This can usually happen during GMM Attach Request. In this scenario, with current code goes into a situation where first the TBF_EV_CONTENTION_RESOLUTION_MS_SUCCESS is triggered and *afterwards* the UL_ACK/NACK state is updated. As a result, the code snippet check above (!tbf_ul_ack_waiting_cnf_final_ack()) will be true and the DL TBF be assigned, but afterwards in the same code path it figures out the final ack happens. In order to fix this, first update the ACK/NACK state and only afterwards trigger the Contention Resolution Success event.

[M] Change in libosmo-sccp[master]: Forbid partial VTY configurations of ASPs with name asp-clnt-*

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sccp/+/33325 ) Change subject: Forbid partial VTY configurations of ASPs with name asp-clnt-* ...................................................................... Forbid partial VTY configurations of ASPs with name asp-clnt-* A recent commit (83db938859428ce3835239e2692d93c557b750e1) changed the behavior of default "sctp-role" and "role" values of ASPs named asp-clnt-* which are used by osmo_sccp_simple_client_on_ss7_id(), in order to avoid having different default values when than function is used, which is totally confusing for end users. As it was already informed when submitting the mentioned commit, it changes the behavior on that specific case, and that made some users start having problems without a proper "your config is wrong!" error. This commit addresses it by basically forbiding that exact use case, that is, partially defining an asp-clnt-* ASP through VTY without explicitly configuring a "role" and "sctp-role". With this patch, function osmo_sccp_simple_client_on_ss7_id() will print a proper error informing the user and will return NULL, potentially triggering an early program exit which can then easily be fixed by using proper configuration.
