[PATCH 2/9] Use helper function to check if an MNCC frame is data (speech/traffic)

Rename method mncc_rcv_tchf() to mncc_rcv_data(), because the check applies to all types of data frames, not only TCH/F data. --- openbsc/include/openbsc/mncc.h | 8 ++++++++ openbsc/src/libmsc/mncc_builtin.c | 22 ++++++++-------------- openbsc/src/libmsc/mncc_sock.c | 3 +-- 3 files changed, 17 insertions(+), 16 deletions(-) diff --git a/openbsc/include/openbsc/mncc.h b/openbsc/include/openbsc/mncc.h index c61f6b8..ffac7fd 100644 --- a/openbsc/include/openbsc/mncc.h +++ b/openbsc/include/openbsc/mncc.h @@ -191,4 +191,12 @@ int mncc_sock_from_cc(struct gsm_network *net, struct msgb *msg); int mncc_sock_init(struct gsm_network *gsmnet); +#define mncc_is_data_frame(msg_type) \ + (msg_type == GSM_TCHF_FRAME \ + || msg_type == GSM_TCHF_FRAME_EFR \ + || msg_type == GSM_TCHH_FRAME \ + || msg_type == GSM_TCH_FRAME_AMR \ + || msg_type == GSM_BAD_FRAME) + + #endif diff --git a/openbsc/src/libmsc/mncc_builtin.c b/openbsc/src/libmsc/mncc_builtin.c index be35454..a5a463b 100644 --- a/openbsc/src/libmsc/mncc_builtin.c +++ b/openbsc/src/libmsc/mncc_builtin.c @@ -273,8 +273,8 @@ static int mncc_rel_cnf(struct gsm_call *call, int msg_type, struct gsm_mncc *re return 0; } -/* receiving a TCH/F frame from the BSC code */ -static int mncc_rcv_tchf(struct gsm_call *call, int msg_type, +/* receiving a (speech) traffic frame from the BSC code */ +static int mncc_rcv_data(struct gsm_call *call, int msg_type, struct gsm_data_frame *dfr) { struct gsm_trans *remote_trans; @@ -339,16 +339,14 @@ int int_mncc_recv(struct gsm_network *net, struct msgb *msg) DEBUGP(DMNCC, "(call %x) Call created.\n", call->callref); } - switch (msg_type) { - case GSM_TCHF_FRAME: - case GSM_TCHF_FRAME_EFR: - break; - default: - DEBUGP(DMNCC, "(call %x) Received message %s\n", call->callref, - get_mncc_name(msg_type)); - break; + if (mncc_is_data_frame(msg_type)) { + rc = mncc_rcv_data(call, msg_type, arg); + goto out_free; } + DEBUGP(DMNCC, "(call %x) Received message %s\n", call->callref, + get_mncc_name(msg_type)); + switch(msg_type) { case MNCC_SETUP_IND: rc = mncc_setup_ind(call, msg_type, arg); @@ -408,10 +406,6 @@ int int_mncc_recv(struct gsm_network *net, struct msgb *msg) call->callref, data->cause.value); rc = mncc_tx_to_cc(net, MNCC_RETRIEVE_REJ, data); break; - case GSM_TCHF_FRAME: - case GSM_TCHF_FRAME_EFR: - rc = mncc_rcv_tchf(call, msg_type, arg); - break; default: LOGP(DMNCC, LOGL_NOTICE, "(call %x) Message unhandled\n", callref); break; diff --git a/openbsc/src/libmsc/mncc_sock.c b/openbsc/src/libmsc/mncc_sock.c index cf4bca8..dd0a44f 100644 --- a/openbsc/src/libmsc/mncc_sock.c +++ b/openbsc/src/libmsc/mncc_sock.c @@ -54,8 +54,7 @@ int mncc_sock_from_cc(struct gsm_network *net, struct msgb *msg) if (net->mncc_state->conn_bfd.fd < 0) { LOGP(DMNCC, LOGL_ERROR, "mncc_sock receives %s for external CC app " "but socket is gone\n", get_mncc_name(msg_type)); - if (msg_type != GSM_TCHF_FRAME && - msg_type != GSM_TCHF_FRAME_EFR) { + if (!mncc_is_data_frame(msg_type)) { /* release the request */ struct gsm_mncc mncc_out; memset(&mncc_out, 0, sizeof(mncc_out)); -- 1.8.1.5 --------------060708050209070502020504 Content-Type: text/x-diff; name="0006-Adding-traffic-forwarding-via-RTP-to-remote-applicat.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename*0="0006-Adding-traffic-forwarding-via-RTP-to-remote-applicat.pa"; filename*1="tch"
