2015-01-10sgsn/doc: Add protocol specification for remote subscriber updateJacob Erlbeck1-0/+385
This is the first version of the specification for the GPRS Subscriber Update Protocol. Sponsored-by: On-Waves ehf
2015-01-10sgsn: Fix VTY command error handling (Coverity)Jacob Erlbeck1-3/+3
Currently the result of the osmo_hexparse function in update_subscr_insert_auth_triplet is not handled correctly. There is a misplaced leading exclamation mark in a few conditional expressions. This effectively disables the error checks, as it is noticed by Coverity ("Missing parentheses" followed by "Logically dead code"). This patch removes the exclamation marks.

2015-01-10meas: Unbreak the build once moreHolger Hans Peter Freyther2-6/+13
The code assumes that sqlite3.h is in the standard include path. Maybe sqlite3 wasn't installed or resides in a non standard (/usr/local) location? Fix the build as it has been broken since 1st of January.

2015-01-05Don't return an error to caller if we are out of lchan on CHAN RQDHarald Welte1-1/+1
This is a normal situation under high load: The BTS is out of resources and the BSC cannot allocate any dedicated channel. We may send an IMM ASS REJECT back to the MS. All well within normal parameters, not an error that needs to be reported back to the caller, who propagates it all the way up to libosmo-abis.

2015-01-02logging: Only compare the subscr addressHolger Hans Peter Freyther7-33/+71
Move the "logging filter imsi IMSI" into the BTS/NITB code to allow to set the gsm_subscriber and only compare it. This way we simply compare the subscriber address and don't have to care if the subscriber data is still valid.

2015-01-02Partial revert "Fix most compiler warnings with gcc-4.9.2"Holger Hans Peter Freyther3-17/+17
Most of the "fixes" have nothing to do with gcc-4.9.2 but are a question of ABI/Architecture (e.g. x86 vs. AMD64). Revert these for now. This partially reverts commit 7b1d25a11e44bbc1cb0d2acd9f1a3d4a16ec7c90. abis_test.c: In function ‘test_simple_sw_config’: abis_test.c:68:2: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘int’ [-Wformat=] printf("Start: %ld len: %zu\n", descr[0].start - simple_config, descr[0].len); ^ abis_test.c: In function ‘test_dual_sw_config’: abis_test.c:111:2: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘int’ [-Wformat=] printf("Start: %ld len: %zu\n", descr[0].start - dual_config, descr[0].len); ^ abis_test.c:115:2: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘int’ [-Wformat=] printf("Start: %ld len: %zu\n", descr[1].start - dual_config, descr[1].len); ^ abis_test.c: In function ‘test_sw_selection’: abis_test.c:132:2: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘int’ [-Wformat=] printf("Start: %ld len: %zu\n", descr[0].start - load_config, descr[0].len); ^ abis_test.c:136:2: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 2 has type ‘int’ [-Wformat=] printf("Start: %ld len: %zu\n", descr[1].start - load_config, descr[1].len);
2015-01-01Merge branch 'laforge/meas_vis'Harald Welte13-4/+1172
I'm merging this code, as it is proven to be very useful. The only reason to keep it out of master was the fact that the UDP data structures it sends are non-portable, so you can only run it reliably on localhost or between identical systems (hardware/compiler/os). As this hasn't been fixed in the past >= 2 years, I am merging the code now anyway. We can still introduce a portable protocol by increasing the protocol version at a later point. There are two options: a) we make 'struct gsm_meas_rep' portable. This requires an ABI change with libosmocore, as it contains struct gsm_meas_rep_unidir :( b) we introduce a completely separate wire format with corresponding encoding and decoding functions.
2015-01-01meas_feed.c: Fix compiler warningHarald Welte1-1/+1
2015-01-01meas_feed: add osmo-meas-udp2db for realtime feed into databaseHarald Welte2-2/+129
This tool can save the meas_feed messages from UDP port 8888 directly to a sqlite3 database for further analysis.
2015-01-01meas_feed: Add tool to read meas_feed PCAP and write it to sqlite3Harald Welte4-2/+489
In fact, the DB write code has been split out so we could later also have a binary that would listen to realtime meas_feed packets and stuff them into a database without any intermediate PCAP step. The database schema contains a couple of convenience wrapper views, most notably the "overview" view.

2015-01-01Initial support for export + curses-visualization of measurementsHarald Welte8-4/+487
This extends osmo_nitb to offer a UDP feed of real-time measurement reports, which can be used by (a variety of) external tools for visualization or other processing. We also add a small ncurses based tool (meas_vis) which shows a baragraph display of the last few mobile stations that were active, indicating their uplink/downlink receive level and quality. <WARNING> This sends non-portable structures like gsm_meas_rep over UDP and assumes the receiver has identical alignment and endianness! Before this feature is merged, it either needs to be converted to a unix domain socket (but they don't do multicast, which would be nice) or the wire format needs to change into something portable with defined alignment and encoding </WARNING>
2015-01-01smscb: Prepare to fill in the info for CBCH in SI4Holger Hans Peter Freyther3-4/+4
Pass the number of bytes the rest octet for si4 should fill.
2015-01-01chan_alloc: remove ts_alloc() and ts_free()Harald Welte2-117/+1
The idea of ts_alloc()/ts_free() dates back to the very early days of OpenBSC, where we didn't yet have a fixed PCHAN type assigned for every lchan in a BTS. However, ever since, PCHAN types (channel combinations) are configured by OML in a certain way, and we only allocate LCHANs inside PCHANs of a matching type. There should be no PCHANs with type GSM_PCHAN_NONE, unless those that you don't want to use for administraive reasons or the like.

2015-01-01chan_alloc.c: Don't remove SDCCH/8 without CBCHHarald Welte1-0/+1
In commit 30f1f376383df3ae8d85e96542bf14d174c25d89 we wanted to add support for SDCCH/8+CBCH, not replace the existing SDCCH/8 with the new CBCH-enabled configuration.

2014-12-30Add basic support for CBCH / SMS-CB (Cell Brroadcast)Harald Welte7-21/+132
We can now configure the pyisical channel types for CBCH either in the CCCH+SDCCH4 or in the SDCCH8 chanel combination. Depending on whether a CBCH exists on the BTS, we also generate the SI4 with matching CBCH channel description to notify the phones of the existance of the CBCH. There is now a VTY command how a SMS-CB message can be sent to a given BTS. We do not yet have any logic at all for actual scheduling of multiple CBCH RSL messages towards one or multiple BTSs yet, though.
2014-12-25rtp: Remove the "correction" of timestampsHolger Hans Peter Freyther1-21/+0
We tend to comment out this code every XXC3, let's just get rid off it. The nanoBTS has a rather odd timing behavior. Jacob has spent hours this summer to trial/document/fix it in the MGCP code and this code is not getting close to working around the ip.access audio issues. If someobody still wants to use the nanoBTS then he should help to have the MGCP MGW use/share code with the rtp_proxy.c
2014-12-25db: Extend the test to mark a SMS as delivered and verify itHolger Hans Peter Freyther1-0/+7
Mark the SMS as delivered, then free it and try to get an undelivered SMS to that subscriber again and make sure it is failing.
2014-12-24sgsn: Add a subscriber based authentication phaseJacob Erlbeck7-82/+311
This implements the MAP way of subscriber validation when the MS tries to perform an Attach Request: 1. perform authentication (optionally invoke the sendAuthInfo procedure), starts the Auth & Ciph procedure 2. perform update location 3. insert subscriber data 4. finish the update location 5. Attach Accept / Attach Reject The authentication triplets are used and eventually updated if all of them have been used. This is currently accessible via the VTY interface by the following commands: - update-subscriber imsi IMSI update-auth-info - update-subscriber imsi IMSI update-location-result (ok|ERR-CAUSE) Sponsored-by: On-Waves ehf
2014-12-24sgsn: Add support for authentication tripletsJacob Erlbeck6-1/+189
This commit add data structures, functions, initialization, and VTY commands for per subscriber authentication triplets. The following VTY command is added: - update-subscriber imsi IMSI \ insert auth-triplet <1-5> sres SRES rand RAND kc KC Note that the triplets are not really used by the SGSN yet.

2014-12-23sgsn: Be more tolerant with state and SUSPEND/RESUMEJacob Erlbeck1-2/+4
Currently, when a BSSGP SUSPEND is received and the corresponding MM context is already in the state GMM_REGISTERED_SUSPENDED, a SUSPEND_NACK is returned which is not covered by GSM 08.18, 7.4.1. The same goes for RESUME in the state GMM_REGISTERED_NORMAL. This commit changes gprs_gmm_rx_suspend and gprs_gmm_rx_resume to not complain (and thus answer a NACK) when the MM context is either in GMM_REGISTERED_SUSPENDED or GMM_REGISTERED_NORMAL. Note that GSM 08.18, 7.4.1 and 7.5.1 only mention to send an NACK if the MS is not known. Even with this patch, the SGSN returns a NACK if either the MS is unknown _or_ the MM context ist not in one of the state GMM_REGISTERED_SUSPENDED and GMM_REGISTERED_NORMAL.

2014-12-23gprs: Add gprs_shift_tlv functionJacob Erlbeck3-9/+42
This function is similar to gprs_match_tlv with the exception, that the tag is not compared but returned in *tag instead. Sponsored-by: On-Waves ehf
2014-12-23gprs: Move TLV parser functions to gprs_utils.c and rename themJacob Erlbeck7-381/+384
Currently the parser functions for single information elements are defined within gprs_gb_parse.c and not exported explicitely. In addition they are named like libosmocore's TLV parser functions and do not have a proper name prefix. Since it is planned to use them for other protocols, they need to be globally accessible. This patch moves them to gprs_utils.c and renames them. The new names are: lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed In the long term, these functions should be moved to libosmocore (and renamed again).

2014-12-18ho: Copy the multirate config to the new lchanHolger Hans Peter Freyther1-0/+1
The new lchan will be in speech mode already but for AMR we will need to provide a working multirate config in the channel activation, otherwise the channel act might be nacked. Copy the config from the current lchan into the new lchan. The abis code simply added the mrconf if the speech mode was amr. Before this commit the invalidate mrconf with all zeroes was copied/sent.
2014-12-17ho: Make sure the timer is always stoppedHolger Hans Peter Freyther1-14/+16
In case of a ho_chan_activ_nack (sent due another bug inside both sysmobts and openbsc) the code would not stop the timer but free the datastructure. This can lead to a clear segfault when the timer has expired. Create a "free" function which is responsible to detach the handover structure, stop the timer (which is idempotent) and free the structure.
2014-12-17bts: When one link drops.. check what needs to be droppedHolger Hans Peter Freyther3-1/+18
In case a BTS is dropped, iterate over the list of BTS and check if a dependency is now missing and then drop the BTS. This check could lead to check of 256*256 checks (e.g. all BTS on each other in the chain and the master is being dropped). The performance aspect of it doesn't matter for our usecase. We expect to have pairs of BTS right now.
2014-12-17bts: Add some simple dependency between different BTSHolger Hans Peter Freyther5-0/+136
E.g. for the sysmoBTS2050 we have the requirement that the first board connects before the second due clocking. The easiest point to enforce this is the BSC. Add a simple bitmask based system to allow to express dependencies for IP based systems.

2014-12-10sgsn: Support subscriber based authenticationJacob Erlbeck5-5/+70
This commit mainly extends sgsn_auth.c to use and support the auth_state SGSN_AUTH_AUTHENTICATE. It will be activated when IMSI and IMEI are available, authentication is required (subscr->sgsn_data->authenticate is set), but the MM context is not marked as authenticated. If the state has been set to SGSN_AUTH_AUTHENTICATE and sgsn_auth_update() is called, the GMM layer will be informed by invoking gsm0408_gprs_authenticate(). Sponsored-by: On-Waves ehf
2014-12-10sgsn: Integrate Auth & Ciph into gsm48_gmm_authorizeJacob Erlbeck3-1/+29
Currently the Authentication and Ciphering procedure is not yet invoked by the GMM layer. This patch starts this procedure from within gsm48_gmm_authorize when the mm->auth_state has been set to SGSN_AUTH_AUTHENTICATE and a call to gsm0408_gprs_authenticate has been issued directly or indirectly by the call to sgsn_auth_request.
