[osmo-bts] Review of jolly/trx jolly/l1sap
by Harald Welte 12 Mar '13

12 Mar '13

Hi Andreas, I've found some time to review the trx and l1sap branches you have created in the osmo-bts.git repository. Let me start by mentioning that I support and encourage your work. However, I think we have to set some general rules before we can merge the code. For us, the most important factor is that we do not loose features or introduce regressions with more or less every new commit to osmo-bts. Furthermore, we would like to stay with 'one commit, one feature/fix'. I understand your primary goal ist go generalize some code and then create a working solution for the OpenBTS or OsmocomBB based transceiver. However, for the way to get the changes are integrated is to first introduce all the infrastructure/core changes while keeping osmo-bts-sysmo functional and that with all existing features. Once those core/infrastructure changes are merged, we can easily include support the extra code for the osmo-bts-trx and in fact even do all development commits to master, as long as they don't touch the core code. Looking at your commits: http://cgit.osmocom.org/cgit/osmo-bts/commit/?h=jolly/trx&id=a82995738303d7… is fine, as it just removes old code. http://cgit.osmocom.org/cgit/osmo-bts/commit/?h=jolly/trx&id=9be2099855532c… looks fine to me, too, we should be able to merge that. My only comment would be: Are you sure this should not be configured via OML from the BSC? I think TS 12.21 Chapter 9.4.14 should be the proper way to configure it. Do you agree? If yes, please use OML configuration and remove the VTY option. http://cgit.osmocom.org/cgit/osmo-bts/commit/?h=jolly/trx&id=7322254e68b7d5… seems fine to me. Can you pleaes confirm from your side that it _should_ not alter/remove any existing code/behavior, but just introduce that L1SAP intermediate interface? Have you tested it with osmo-bts-sysmo? http://cgit.osmocom.org/cgit/osmo-bts/commit/?h=jolly/trx&id=1c3712962195d1… seems to not just remove the direct handling of primitives, but also add some code, particularly the gsmtap_ip command line argument. Can you please split that in a separate patch? Also, have you tested osmo-bts-sysmo after this commit?

Do you remember your test setup and the results of it? There appears to be an issue with iPhone4s and iPhone5 phones (and PCS). It appears to me that there are at least three issues with the generation: * The SI1 rest_octets indicated DCS while PCS was used (this is fixed) * The Ext-Ind claims that SI2 carries the complete BA even if SI2ter/2bis are scheduled. * The BA-Ind is the same for SDCCH/BCCH. We should use 0/1. Could you have a look at it? thanks holger

[PATCH] Added a ring buffer log target to store the last N log messages.
by Katerina Barone-Adesi 11 Mar '13

11 Mar '13

The log target can be used via log alarms and show alarms. Why? This feature was proposed/requested at http://openbsc.osmocom.org/trac/wiki/Tasks/ErrorLogTarget All messages use the same amount of space, prioritizing simplicity. Renames as per tnt's request. UI changed to reflect number of usable messages, as per zecke's request. --- .gitignore | 2 + include/osmocom/core/logging.h | 5 + include/osmocom/core/loggingrb.h | 40 +++++++ include/osmocom/core/strrb.h | 58 ++++++++++ src/Makefile.am | 4 +- src/loggingrb.c | 98 +++++++++++++++++ src/strrb.c | 170 +++++++++++++++++++++++++++++ src/vty/logging_vty.c | 85 ++++++++++++++- tests/Makefile.am | 13 ++- tests/loggingrb/logging_test.err | 3 + tests/loggingrb/logging_test.ok | 0 tests/loggingrb/loggingrb_test.c | 83 +++++++++++++++ tests/strrb/strrb_test.c | 225 +++++++++++++++++++++++++++++++++++++++ tests/strrb/strrb_test.ok | 1 + tests/testsuite.at | 13 +++ 15 files changed, 792 insertions(+), 8 deletions(-) create mode 100644 include/osmocom/core/loggingrb.h create mode 100644 include/osmocom/core/strrb.h create mode 100644 src/loggingrb.c create mode 100644 src/strrb.c create mode 100644 tests/loggingrb/logging_test.err create mode 100644 tests/loggingrb/logging_test.ok create mode 100644 tests/loggingrb/loggingrb_test.c create mode 100644 tests/strrb/strrb_test.c create mode 100644 tests/strrb/strrb_test.ok diff --git a/.gitignore b/.gitignore index 24ca677..aedd9fd 100644 --- a/.gitignore +++ b/.gitignore @@ -69,6 +69,8 @@ tests/gb/bssgp_fc_test tests/gsm0408/gsm0408_test tests/logging/logging_test tests/fr/fr_test +tests/loggingrb/loggingrb_test +tests/ringbuf/ringbuf_test utils/osmo-arfcn utils/osmo-auc-gen diff --git a/include/osmocom/core/logging.h b/include/osmocom/core/logging.h index 54262b7..fa3365a 100644 --- a/include/osmocom/core/logging.h +++ b/include/osmocom/core/logging.h @@ -114,6 +114,7 @@ enum log_target_type { LOG_TGT_TYPE_SYSLOG, /*!< \brief syslog based logging */ LOG_TGT_TYPE_FILE, /*!< \brief text file logging */ LOG_TGT_TYPE_STDERR, /*!< \brief stderr logging */ + LOG_TGT_TYPE_STRRB, /*!< \brief osmo_strrb-backed logging */ }; /*! \brief structure representing a logging target */ @@ -154,6 +155,10 @@ struct log_target { struct { void *vty; } tgt_vty; + + struct { + void *rb; + } tgt_rb; }; /*! \brief call-back function to be called when the logging framework diff --git a/include/osmocom/core/loggingrb.h b/include/osmocom/core/loggingrb.h new file mode 100644 index 0000000..a6f377b --- /dev/null +++ b/include/osmocom/core/loggingrb.h @@ -0,0 +1,40 @@ +#ifndef _LOGGINGRB_H +#define _LOGGINGRB_H + +/* (C) 2012-2013 by Katerina Barone-Adesi <kat.obsc(a)gmail.com> + * All Rights Reserved + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

rtp handling for all speech codecs
by jolly 11 Mar '13

11 Mar '13

hi, long time ago i had these patches at a seperate "rtpmux" branch. now i added them to a new branch (jolly/trx). they are very well tested now, and i think they should get merged after some review. it is my aim to support all speech codecs at osmo-nitb (built-in call handling, as well as MNCC socket interface). these patches are essential for patches that will follow during next weeks. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=f029472c1e4… Adding traffic forwarding via RTP to remote application Instead of forwarding traffic through MNCC interface, traffic can now be forwarded to a given RTP destination. A special MNCC message is used for that. The traffic can still be forwarded through MNCC interface when this special MNCC message is not used. It also works with E1 based BTSs. In conjunction with LCR's "rtp-bridge" feature, the RTP traffic can be directly exchanged with a remote SIP endpoint, so that the traffic is not forwarded by LCR itself. This way the performance of handling traffic only depends on OpenBSC and the remote SIP endpoint. Also the traffic is exchanged with the SIP endpoint without transcoding, to have maximum performance. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=eb333169ae0… Adding handling of BFI (Bad Frame Indicatior) of received TRAU frames If a bad TRAU frame is received, it is forwarded to MNCC application as GSM_TCHF_BAD_FRAME. The application can now handle the GAP of missing audio. (e.g. with extrapolation) If TRAU frames are forwarded via RTP, bad frames are dropped, but frame counter and timestamp of RTP sender state is increased. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=7fb2bf09ec2… Allow dynamic RTP payload types between application and MNCC interface Since EFR/AMR/HR codecs use dynamic RTP payload, the payload type can be set. If it is set, the frame type must be set also, so OpenBSC knows what frame types are received via RTP. This modification only affects traffic beween application and MNCC interface, not the RTP traffic between OpenBSC and BTS. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=42eb7251b96… Fixed delay problems, if RTP stream jitters too much The RTP stream is generated or forwarded by OpenBSC to nanoBTS. Due to switching of streams (hold/retrieve call), packet loss or even stalling of sender's process, the time stamp must be corrected. If outdated packets are received, they get dropped. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=ee20ef2691f… Finished support for all codecs (RTP bridge and MNCC interface) The code is not yet tested. AMR rate is currently fixed to 5.9k. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=5140fa39898… Fixed problem of mute audio on some calls When reading from RTP socket, the first read() may fail right after connecting to remote socket. Subsequent read() will work as it should. I have not checked why this read fails, but I don't see any reason why we should stop reading, just because one read() fails at the beginning. http://cgit.osmocom.org/cgit/openbsc/commit/?h=jolly/testing&id=82e1a17ecb7… Fix: TCHH/HR payloads are 15 bytes (ToC + 14 bytes of speech data) note: this last fix can be applied to the patches above, rather than merged seperately. any suggestions? andreas

[PATCH] VTY enable then write crashed gproxy; this patch fixes it.
by Katerina Barone-Adesi 03 Mar '13

03 Mar '13

The previous code made gprs_categories have 18 entries, rather than the 3 a glance would suggest. The first 15 were all-0, as per implicit initialization of static objects in the c standard. This caused problems for code in libosmocore which expected actual data. There are three potential solutions: a) Define a new enum for gprs_categories b) Change libosmocore to not crash on all-zero input categories. c) Simply use log_info, which has a superset of the information. This patch implements c, the simplest. sgsn_main.c had a similar problem; it implicitly had 20 categories. (see readelf -s gprs/osmo-sgsn | grep gprs_categories). --- openbsc/src/gprs/gb_proxy_main.c | 28 ++---------------- openbsc/src/gprs/sgsn_main.c | 62 ++-------------------------------------- 2 files changed, 4 insertions(+), 86 deletions(-) diff --git a/openbsc/src/gprs/gb_proxy_main.c b/openbsc/src/gprs/gb_proxy_main.c index b5b11fd..0a96527 100644 --- a/openbsc/src/gprs/gb_proxy_main.c +++ b/openbsc/src/gprs/gb_proxy_main.c @@ -200,30 +200,6 @@ static struct vty_app_info vty_info = { .is_config_node = bsc_vty_is_config_node, }; -/* default categories */ -static struct log_info_cat gprs_categories[] = { - [DGPRS] = { - .name = "DGPRS", - .description = "GPRS Packet Service", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, - [DNS] = { - .name = "DNS", - .description = "GPRS Network Service (NS)", - .enabled = 1, .loglevel = LOGL_INFO, - }, - [DBSSGP] = { - .name = "DBSSGP", - .description = "GPRS BSS Gateway Protocol (BSSGP)", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, -}; - -static const struct log_info gprs_log_info = { - .filter_fn = gprs_log_filter_fn, - .cat = gprs_categories, - .num_cat = ARRAY_SIZE(gprs_categories), -}; int main(int argc, char **argv) { @@ -239,11 +215,11 @@ int main(int argc, char **argv) signal(SIGUSR2, &signal_handler); osmo_init_ignore_signals(); - osmo_init_logging(&gprs_log_info); + osmo_init_logging(&log_info); vty_info.copyright = openbsc_copyright; vty_init(&vty_info); - logging_vty_add_cmds(&gprs_log_info); + logging_vty_add_cmds(&log_info); gbproxy_vty_init(); handle_options(argc, argv); diff --git a/openbsc/src/gprs/sgsn_main.c b/openbsc/src/gprs/sgsn_main.c index 08e0a85..e5161b4 100644 --- a/openbsc/src/gprs/sgsn_main.c +++ b/openbsc/src/gprs/sgsn_main.c @@ -227,64 +227,6 @@ static void handle_options(int argc, char **argv) } } -/* default categories */ -static struct log_info_cat gprs_categories[] = { - [DMM] = { - .name = "DMM", - .description = "Layer3 Mobility Management (MM)", - .color = "\033[1;33m", - .enabled = 1, .loglevel = LOGL_NOTICE, - }, - [DPAG] = { - .name = "DPAG", - .description = "Paging Subsystem", - .color = "\033[1;38m", - .enabled = 1, .loglevel = LOGL_NOTICE, - }, - [DMEAS] = { - .name = "DMEAS", - .description = "Radio Measurement Processing", - .enabled = 0, .loglevel = LOGL_NOTICE, - }, - [DREF] = { - .name = "DREF", - .description = "Reference Counting", - .enabled = 0, .loglevel = LOGL_NOTICE, - }, - [DGPRS] = { - .name = "DGPRS", - .description = "GPRS Packet Service", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, - [DNS] = { - .name = "DNS", - .description = "GPRS Network Service (NS)", - .enabled = 1, .loglevel = LOGL_INFO, - }, - [DBSSGP] = { - .name = "DBSSGP", - .description = "GPRS BSS Gateway Protocol (BSSGP)", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, - [DLLC] = { - .name = "DLLC", - .description = "GPRS Logical Link Control Protocol (LLC)", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, - [DSNDCP] = { - .name = "DSNDCP", - .description = "GPRS Sub-Network Dependent Control Protocol (SNDCP)", - .enabled = 1, .loglevel = LOGL_DEBUG, - }, -}; - -static const struct log_info gprs_log_info = { - .filter_fn = gprs_log_filter_fn, - .cat = gprs_categories, - .num_cat = ARRAY_SIZE(gprs_categories), -}; - - int main(int argc, char **argv) { struct gsm_network dummy_network; @@ -299,11 +241,11 @@ int main(int argc, char **argv) signal(SIGUSR2, &signal_handler); osmo_init_ignore_signals(); - osmo_init_logging(&gprs_log_info); + osmo_init_logging(&log_info); vty_info.copyright = openbsc_copyright; vty_init(&vty_info); - logging_vty_add_cmds(&gprs_log_info); + logging_vty_add_cmds(&log_info); sgsn_vty_init(); handle_options(argc, argv); -- 1.8.1.2

[PATCH] Stub changes for vty documentation
by Katerina Barone-Adesi 03 Mar '13

03 Mar '13

contrib/dump_all_data.py showed several (null) documentation messages. This patch aims to show what needs to be documented. Please do not apply this patch as-is: this is stub documentation, which needs to be edited by someone familiar with the particular VTY commands. --- openbsc/src/libbsc/bsc_vty.c | 4 ++-- openbsc/src/libmgcp/mgcp_vty.c | 4 ++-- openbsc/src/libmsc/vty_interface_layer3.c | 6 ++++-- openbsc/src/osmo-bsc/osmo_bsc_vty.c | 7 ++++--- 4 files changed, 12 insertions(+), 9 deletions(-) diff --git a/openbsc/src/libbsc/bsc_vty.c b/openbsc/src/libbsc/bsc_vty.c index ec92c18..29ec065 100644 --- a/openbsc/src/libbsc/bsc_vty.c +++ b/openbsc/src/libbsc/bsc_vty.c @@ -2644,7 +2644,7 @@ DEFUN(cfg_ts, DEFUN(cfg_ts_pchan, cfg_ts_pchan_cmd, "phys_chan_config PCHAN", /* dynamically generated! */ - "Physical Channel configuration (TCH/SDCCH/...)") + "Physical Channel configuration (TCH/SDCCH/...)\n" "PCHAN\n") { struct gsm_bts_trx_ts *ts = vty->index; int pchanc; @@ -2663,7 +2663,7 @@ DEFUN(cfg_ts_pchan, DEFUN_HIDDEN(cfg_ts_pchan_compat, cfg_ts_pchan_compat_cmd, "phys_chan_config PCHAN", - "Physical Channel configuration (TCH/SDCCH/...)") + "Physical Channel configuration (TCH/SDCCH/...)\n" "PCHAN\n") { struct gsm_bts_trx_ts *ts = vty->index; int pchanc; diff --git a/openbsc/src/libmgcp/mgcp_vty.c b/openbsc/src/libmgcp/mgcp_vty.c index 88d793f..9e3051d 100644 --- a/openbsc/src/libmgcp/mgcp_vty.c +++ b/openbsc/src/libmgcp/mgcp_vty.c @@ -327,7 +327,7 @@ ALIAS_DEPRECATED(cfg_mgcp_rtp_ip_dscp, cfg_mgcp_rtp_ip_tos_cmd, DEFUN(cfg_mgcp_sdp_fmtp_extra, cfg_mgcp_sdp_fmtp_extra_cmd, "sdp audio fmtp-extra .NAME", - "Add extra fmtp for the SDP file\n") + "Add extra fmtp for the SDP file\n" "Audio\n" "Fmtp-extra\n" "Name\n") { char *txt = argv_concat(argv, argc, 0); if (!txt) @@ -508,7 +508,7 @@ static int config_write_trunk(struct vty *vty) DEFUN(cfg_trunk_sdp_fmtp_extra, cfg_trunk_sdp_fmtp_extra_cmd, "sdp audio fmtp-extra .NAME", - "Add extra fmtp for the SDP file\n") + "Add extra fmtp for the SDP file\n" "Audio\n" "Fmtp-extra\n" "Name\n") { struct mgcp_trunk_config *trunk = vty->index; char *txt = argv_concat(argv, argc, 0); diff --git a/openbsc/src/libmsc/vty_interface_layer3.c b/openbsc/src/libmsc/vty_interface_layer3.c index 441ee1e..efd1e9b 100644 --- a/openbsc/src/libmsc/vty_interface_layer3.c +++ b/openbsc/src/libmsc/vty_interface_layer3.c @@ -231,7 +231,7 @@ DEFUN(subscriber_send_pending_sms, DEFUN(subscriber_send_sms, subscriber_send_sms_cmd, "subscriber " SUBSCR_TYPES " ID sms sender " SUBSCR_TYPES " SENDER_ID send .LINE", - SUBSCR_HELP "SMS Operations\n" "Send SMS\n" "Actual SMS Text") + SUBSCR_HELP "SMS Operations\n" SUBSCR_HELP "Actual SMS Text\n" "LINE\n") { struct gsm_network *gsmnet = gsmnet_from_vty(vty); struct gsm_subscriber *subscr = get_subscr_by_argv(gsmnet, argv[0], argv[1]); @@ -911,11 +911,13 @@ DEFUN(mnccint_def_codec_h, return CMD_SUCCESS; } +#define OBSOLETE_MSG "Obsolete\n" /* this is just for backwards compatibility as the sms code moved into * libosmocore and old config files no longer parse... */ DEFUN_DEPRECATED(log_level_sms, log_level_sms_cmd, "logging level sms (everything|debug|info|notice|error|fatal)", - ".HIDDEN") + ".HIDDEN\n" OBSOLETE_MSG OBSOLETE_MSG OBSOLETE_MSG OBSOLETE_MSG + OBSOLETE_MSG OBSOLETE_MSG OBSOLETE_MSG OBSOLETE_MSG) { vty_out(vty, "%% 'logging level sms' is now called 'logging level " "lsms', please update your config %s", VTY_NEWLINE); diff --git a/openbsc/src/osmo-bsc/osmo_bsc_vty.c b/openbsc/src/osmo-bsc/osmo_bsc_vty.c index fb38848..ff235e7 100644 --- a/openbsc/src/osmo-bsc/osmo_bsc_vty.c +++ b/openbsc/src/osmo-bsc/osmo_bsc_vty.c @@ -180,7 +180,7 @@ static int config_write_bsc(struct vty *vty) DEFUN(cfg_net_bsc_token, cfg_net_bsc_token_cmd, "token TOKEN", - "A token for the BSC to be sent to the MSC") + "A token for the BSC to be sent to the MSC\n" "A token\n") { struct osmo_msc_data *data = osmo_msc_data(vty); @@ -335,7 +335,8 @@ DEFUN(cfg_net_msc_no_dest, DEFUN(cfg_net_msc_ping_time, cfg_net_msc_ping_time_cmd, "timeout-ping NR", - "Set the PING interval, negative for not sending PING") + "Set the PING interval, negative for not sending PING.\n" + "Timeout in seconds\n") { struct osmo_msc_data *data = osmo_msc_data(vty); data->ping_timeout = atoi(argv[0]); @@ -345,7 +346,7 @@ DEFUN(cfg_net_msc_ping_time, DEFUN(cfg_net_msc_pong_time, cfg_net_msc_pong_time_cmd, "timeout-pong NR", - "Set the time to wait for a PONG.") + "Set the time to wait for a PONG.\n" "Timeout in seconds\n") { struct osmo_msc_data *data = osmo_msc_data(vty); data->pong_timeout = atoi(argv[0]); -- 1.8.1.2
