[S] Change in libosmo-sccp[master]: fix sccp_scoc state S_WAIT_CONN_CONF out_state_mask

by neels

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmo-sccp/+/32035 ) Change subject: fix sccp_scoc state S_WAIT_CONN_CONF out_state_mask ...................................................................... fix sccp_scoc state S_WAIT_CONN_CONF out_state_mask In sccp_scoc_states, allow the state transitions present in S_WAIT_CONN_CONF's event handler function scoc_fsm_wait_conn_conf(), and thus fix handling of N-DISCONNECT while waiting for SCCP Conn Confirm. Fixes this error: DLSCCP ERROR SCCP-SCOC(1016){WAIT_CONN_CONF}: transition to state IDLE not permitted! (sccp_scoc.c:1213) S_WAIT_CONN_CONF happens when the caller sends an N-DISCONNECT during S_CONN_PEND_OUT -- that means, while we are waiting for a CC from the peer, the caller ends the conn. SCCP-SCOC still waits for the CC first. When S_WAIT_CONN_CONF expires, the intended path is state change to S_IDLE, which then deallocates the connection. Allow this state transition from S_WAIT_CONN_CONF to S_IDLE. When S_WAIT_CONN_CONF receives a CC, the intended path is to send a RELRE and state change to S_DISCONN_PEND. Allow this state transition from S_WAIT_CONN_CONF to S_DISCONN_PEND.

[M] Change in libosmocore[master]: codec: add osmo_efr_check_sid() function

by falconia

falconia has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/32034 ) Change subject: codec: add osmo_efr_check_sid() function ...................................................................... codec: add osmo_efr_check_sid() function Previously existing code provides osmo_fr_check_sid() and osmo_hr_check_sid() functions for FR1 and HR1 codecs; these functions are used by various RTP-touching programs in the Osmocom CNI suite when they need to differentiate between speech and SID frames. However, there was no corresponding function of this form for EFR codec, with the result being that the same programs that handle speech vs SID distinction correctly for FR1 and HR1 fail to do so for EFR. The present change adds an osmo_efr_check_sid() function to libosmocodec that fully mirrors previously existing osmo_fr_check_sid() and osmo_hr_check_sid(), providing the first step toward more correct EFR handling in programs where a SID check may be needed.
