[PATCH openBSC] libmgcp: add enum mgcp_type
by pablo＠gnumonks.org 06 Jul '13

06 Jul '13

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> This patch replaces the field 'is_transcoded' in the mgcp_endpoint structure by the enum mgcp_type, that can be further extended with new types. --- openbsc/include/openbsc/mgcp_internal.h | 7 ++++++- openbsc/src/libmgcp/mgcp_network.c | 34 +++++++++++++++++++++++-------- openbsc/src/libmgcp/mgcp_protocol.c | 8 ++++---- 3 files changed, 36 insertions(+), 13 deletions(-) diff --git a/openbsc/include/openbsc/mgcp_internal.h b/openbsc/include/openbsc/mgcp_internal.h index 455bb53..d5bd3dd 100644 --- a/openbsc/include/openbsc/mgcp_internal.h +++ b/openbsc/include/openbsc/mgcp_internal.h @@ -96,6 +96,11 @@ struct mgcp_rtp_tap { struct sockaddr_in forward; }; +enum mgcp_type { + MGCP_RTP_DEFAULT = 0, + MGCP_RTP_TRANSCODED, +}; + struct mgcp_endpoint { int allocated; uint32_t ci; @@ -119,7 +124,7 @@ struct mgcp_endpoint { */ struct mgcp_rtp_end trans_bts; struct mgcp_rtp_end trans_net; - int is_transcoded; + enum mgcp_type type; /* sequence bits */ struct mgcp_rtp_state net_state; diff --git a/openbsc/src/libmgcp/mgcp_network.c b/openbsc/src/libmgcp/mgcp_network.c index a2cfc23..7eaacf5 100644 --- a/openbsc/src/libmgcp/mgcp_network.c +++ b/openbsc/src/libmgcp/mgcp_network.c @@ -371,10 +371,19 @@ static int rtp_data_net(struct osmo_fd *fd, unsigned int what) endp->net_end.octets += rc; forward_data(fd->fd, &endp->taps[MGCP_TAP_NET_IN], buf, rc); - if (endp->is_transcoded) - return send_transcoder(&endp->trans_net, endp->cfg, proto == PROTO_RTP, &buf[0], rc); - else - return send_to(endp, DEST_BTS, proto == PROTO_RTP, &addr, &buf[0], rc); + + switch (endp->type) { + case MGCP_RTP_DEFAULT: + return send_to(endp, DEST_BTS, proto == PROTO_RTP, &addr, + buf, rc); + case MGCP_RTP_TRANSCODED: + return send_transcoder(&endp->trans_net, endp->cfg, + proto == PROTO_RTP, buf, rc); + default: + LOGP(DMGCP, LOGL_ERROR, "Bad MGCP type %u on endpoint %u\n", + endp->type, ENDPOINT_NUMBER(endp)); + } + return 0; } static void discover_bts(struct mgcp_endpoint *endp, int proto, struct sockaddr_in *addr) @@ -450,10 +459,19 @@ static int rtp_data_bts(struct osmo_fd *fd, unsigned int what) endp->bts_end.octets += rc; forward_data(fd->fd, &endp->taps[MGCP_TAP_BTS_IN], buf, rc); - if (endp->is_transcoded) - return send_transcoder(&endp->trans_bts, endp->cfg, proto == PROTO_RTP, &buf[0], rc); - else - return send_to(endp, DEST_NETWORK, proto == PROTO_RTP, &addr, &buf[0], rc); + + switch (endp->type) { + case MGCP_RTP_DEFAULT: + return send_to(endp, DEST_NETWORK, proto == PROTO_RTP, &addr, + buf, rc); + case MGCP_RTP_TRANSCODED: + return send_transcoder(&endp->trans_bts, endp->cfg, + proto == PROTO_RTP, buf, rc); + default: + LOGP(DMGCP, LOGL_ERROR, "Bad MGCP type %u on endpoint %u\n", + endp->type, ENDPOINT_NUMBER(endp)); + } + return 0; } static int rtp_data_transcoder(struct mgcp_rtp_end *end, struct mgcp_endpoint *_endp, diff --git a/openbsc/src/libmgcp/mgcp_protocol.c b/openbsc/src/libmgcp/mgcp_protocol.c index dc5e0f9..1e1841a 100644 --- a/openbsc/src/libmgcp/mgcp_protocol.c +++ b/openbsc/src/libmgcp/mgcp_protocol.c @@ -500,7 +500,7 @@ static int allocate_ports(struct mgcp_endpoint *endp) } /* remember that we have set up transcoding */ - endp->is_transcoded = 1; + endp->type = MGCP_RTP_TRANSCODED; } return 0; @@ -1014,7 +1014,7 @@ void mgcp_free_endp(struct mgcp_endpoint *endp) mgcp_rtp_end_reset(&endp->net_end); mgcp_rtp_end_reset(&endp->trans_net); mgcp_rtp_end_reset(&endp->trans_bts); - endp->is_transcoded = 0; + endp->type = MGCP_RTP_DEFAULT; memset(&endp->net_state, 0, sizeof(endp->net_state)); memset(&endp->bts_state, 0, sizeof(endp->bts_state)); @@ -1118,7 +1118,7 @@ static void create_transcoder(struct mgcp_endpoint *endp) int in_endp = ENDPOINT_NUMBER(endp); int out_endp = endp_back_channel(in_endp); - if (!endp->is_transcoded) + if (endp->type != MGCP_RTP_TRANSCODED) return; send_msg(endp, in_endp, endp->trans_bts.local_port, "CRCX", "sendrecv"); @@ -1140,7 +1140,7 @@ static void delete_transcoder(struct mgcp_endpoint *endp) int in_endp = ENDPOINT_NUMBER(endp); int out_endp = endp_back_channel(in_endp); - if (!endp->is_transcoded) + if (endp->type != MGCP_RTP_TRANSCODED) return; send_dlcx(endp, in_endp); -- 1.7.10.4

[PATCH] Fix IE lengths in the sgsn code
by Alexander Chemeris 04 Jul '13

04 Jul '13

Hi all, Attached patch fixes lengths of MS Network Capability and MS Radio Access Capability elements. Original code was inconsistent about lengths and could lead to out of bounds write. Lengths were also inconsistent with the TS 24.008. -- Regards, Alexander Chemeris. CEO, Fairwaves LLC / ООО УмРадио http://fairwaves.ru

Nokia InSite configuration check
by Sipos Csaba 30 Jun '13

30 Jun '13

Dear members, In connection with the problem I found, I kindly ask someone, to please check my configuration, because I want to rule out any configuration related issue, don't want to waste anyones time with sending false bug reports. Currently I am using a GSM1800 Nokia InSite unit with a Dahdi E1 card and OpenBSC, the DAHDI card is the timing source. /etc/dahdi/system.conf span=1,0,0,ccs,hdb3,crc4 bchan=2-31 dchan=1 OpenBSC conf: password foo line vty no login e1_input e1_line 0 driver dahdi network network country code 1 mobile network code 1 short name OpenBSC long name OpenBSC mm info 1 timer t3101 10 timer t3113 60 bts 0 type nokia_site band GSM1800 cell_identity 1 location_area_code 1 base_station_id_code 63 training_sequence_code 7 ms max power 40 periodic location update 10 oml e1 line 0 timeslot 5 sub-slot full oml e1 tei 1 trx 0 arfcn 885 nominal power 22 max_power_red 0 rsl e1 line 0 timeslot 4 sub-slot full rsl e1 tei 1 timeslot 0 phys_chan_config CCCH+SDCCH4 e1 line 0 timeslot 2 sub-slot 0 timeslot 1 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 1 timeslot 2 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 2 timeslot 3 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 3 timeslot 4 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 0 timeslot 5 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 1 timeslot 6 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 2 timeslot 7 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 3 My main concern is about the OML and RSL TEI addresses. If I understand it correctly, OML TEI identifies the BTS, RSL TEI identifies the TRX of that BTS. So if I have 2 BTSs and 2-2 TRXs, then the correct configuration would be looking like this: BTS0: oml: te1 1 trx0: tei 1 trx1: tei 2 trx2: tei 3 .... BTS1: oml: tei 2 trx0: tei 1 trx1: tei 2 trx2: tei 3 ... ? Even the Nokia BTS commissioning documentation is unclear about the specifics: sapi =Service access point identifier. (62 for OMUSIG, 0 for TRXSIG.) tei =Terminal end point identifier. Must the same as defined in the BTS. Usually the same as the TRX number. For OMU link, the value is 1. According to this, every OML TEI of every BTS should be "1" ? The other funny part is, that it sais it must be the same as defined in the BTS, but Nokia BTS Manager does not have any parameter for TEI or SAPI to set. My other concerns are BSIC and Training Sequence Code (TSC). As I know, BSIC identifies the BTS in a location and/or routing area, it means that a location/routing area can have 64 BTSs at top (BSIC=0-63), and every BTS have to use unique BSIC in the same LAC? TSC is another mystery. Nokia Docs sais: train_seq = Training sequence code. (eg. BCC value of the BSIC, eg. 7) This has to be 7 all the time, or if I have more than one BTS (in the same LAC and on the same E1)I have to change this? Finally, DAHDI configuration: How many D channels should I specify? For example if I have 2 BTSs on the same E1, I have to specify two D channels for every OMUSIG timeslots? Or I have to specify D channels for every timeslots I use for signalling (OMUSIG and TRXSIG for all BTSs)? Or maybe I don't have to allocate even one D channel, because I dedicate separate signalling and TCH timeslots for every BTS? I searched a lot about this topic, but the information available is limited, not specific and most of the time lead to more questions... I hope someone can enlighten me in this topic. BR, Csaba

[PATCH] contrib: A shell script to send command(s) to osmo-nitb/osmo-bts live instances.
by Alexander Chemeris 30 Jun '13

30 Jun '13

Hi all, Attached is a shell script I found useful for monitoring a live installation of OsmoNITB. I hope it'll be useful for someone else and propose to check it into the 'contrib' directory of the OpenBSC repository. Actually I believe that Holger's zecke/features/nitb-ctrl-interface branch should be merged into the master, as it makes such monitoring much easier and failsafe. PS I think it would be useful create a wiki-page with cheat-sheet of useful commands during the OpenBSC operation. I could start putting something together if there are no objections to that. I would appreciate recommendations for the wiki page name and location too. -- Regards, Alexander Chemeris. CEO, Fairwaves LLC / ООО УмРадио http://fairwaves.ru

(e.g. handling of many measurement reports) one solution is to have an own thread for the audio processing. this thread must access different interfaces independently from the rest of the openbsc code: - RTP sockets - MNCC socket - TRAU sockets of E1 timeslots MNCC socket could be split into two sockets: one for signalling, one for audio traffic. this way it is not required to use queues and signals between main thread and audio thread. a problem in case of multithreading is osmo_select_main(). it uses global list of file descriptors and global rb-tree for timers. one solution would be having multiple lists and trees for each thread id. this way it is not required to change timer and file descriptor api. another solution could be a seperate process, which handles audio only. i don't really like a sepeate process, since it requires some interface to openbsc and makes everything more complex. even though i don't like threads, multithreading seems to be the best solution to me at the moment. was there any effort to solve the problem or to handle audio? are there any suggestions about it? regard, andreas
