  • Patch Set #1, Line 183: uint32_t tlli = 0xe1c5d364;

    I still need to find out how to identify a given MS in the SN SAP of SNDCP. […]

    I think I can retrieve it in the hook/forward of SNSM-ACTIVATE.ind/cnf in sndcp.c
    In there I get NSAPI, SAPI, and TLLI, check 3GPP TS 44.065.

    our libosmo-gprs-sm seems to be wrong and passing PTMSI instead:
    gprs_sm_submit_snsm_act_ind() {
    ...
    	sndcp_prim_tx = osmo_gprs_sndcp_prim_alloc_snsm_activate_ind(
    				sme->ms->gmm.ptmsi,
    				sme->nsapi,
    				sme->llc_sapi);
    ...
    }

    Actually the whole SM layer seems to still use PTMSI vs TLLI the wrong way?
    """
    struct gprs_sm_ms *gprs_sm_find_ms_by_tlli(uint32_t tlli)
    {
    	struct gprs_sm_ms *ms;

    	llist_for_each_entry(ms, &g_sm_ctx->ms_list, list) {
    		if (ms->gmm.ptmsi == tlli)
    			return ms;
    	}
    	return NULL;
    }
