2017-07-12move openbsc/* to repos rootNeels Hofmeyr1-4304/+0
This is the first step in creating this repository from the legacy openbsc.git. Like all other Osmocom repositories, keep the autoconf and automake files in the repository root. openbsc.git has been the sole exception, which ends now. Change-Id: I9c6f2a448d9cb1cc088cf1cf6918b69d7e69b4e7
2017-06-18Add vty command "radio-link-timeout infinite" for uplink rx testingHarald Welte1-4/+25
When we are performing Rx sensitivity testing on a BTS, we want to deactivate the connection failure criterion / radio link timeout, i.e. no matter how many SACCH frames in uplink are failed to decode, the BTS should never close the channel. OsmoBTS Change-Id I736f21f6528db5c16fa80cdb905af20673797be5 covers a way how this behavior can be requested from the BTS via an OML attribute. This patch adds support to the BSC to actually set that attribute. Do not use this in production networks, as the BTS will keep open radio channels indefinitely even if the phone is gone and no longer transmitting anything. This is a pure testing feature.

2017-06-15Update SI data structures and generationMax1-48/+30
To support segmented SI2quater as per 3GPP TS 44.018 we'll have to support multiple SI messages (up to 16 for SI2q) for a given type in contrast to existing 1:1 mapping: * expand storage space to hold up to 16 SI messages (spec limit) * add assertions for budget calculations * generate multiple SI2q messages * adjust SI2q-related tests * use precise check for number of SIq messages instead of approximate estimation Change-Id: Ic516ec9f0b821557d9461ae9f1c0afdd786f3b05 Related: OS#1660

2017-05-29libbsc: Create pcu-socket only as specified in config fileHarald Welte1-0/+26
Since commit b4999b60d48bcbb5aa575973d068e07ab672e095 we created PCU sockets at hard-coded paths in the filesystem by default for all BTSs. This is inflexible and prevents the use of multiple BSC instances on a single filesystem, or the placement of the sockets in a more secure location than /tmp. The new approach with this patch is that * no PCU sockets are created by default * only for those BTSs where a 'pcu-socket' is configured via VTY, the socket will actually be created Change-Id: Ie9079470584777dcc31f85f9bf0808f479156ccb Closes: OS#2293
2017-05-28bsc_vty: Add command to manually issue IPAC MDCXHarald Welte1-1/+31
Using this command, one can modify the RTP stream associated with a given logical channel and (re)direct it to a specified IP:Port. Change-Id: I63e03b932038a4e2f6d51c5541b52e4a42df27bf
2017-05-27bsc_vty.c: Add command for manual [de]actiovation of logical channelsHarald Welte1-0/+119
Sometimes it is useful to manually activate (or decativate) a given logical channel from the VTY. Doing this on the BSC (rather than the BTS) ensures that the BSC knows that this timeslot / channel is allocated and there is no risk to have clashes between the BSC "owning" the resources and the BTS allocating some by itself.

2017-04-28Prepare for extended SI2quater supportMax1-5/+5
Supporting SI2quater as per 3GPP TS 44.018 will require chnages to the way System Information is stored because it uses 1:n instead of 1:1 mapping between SI type and generated SI content. This should not affect other SI types though. To facilitate this transition: * convert the code to always use GSM_BTS_SI helper instead of accessing buffer directly * make helper more robust by adding extra parenthesis * add similar helper for gsm_lchan * add function estimating number of SI2quater message to hold configured number of (U|E)ARFCNs * add SI2q index/count fields and pass them to rest_octets generator explicitly * internalize buffer access in generate_si* functions Change-Id: I74e4e3cb86364cec869a1472a41b4a95af0d50dd Related: RT#8792

2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr1-1/+11
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC subscriber: struct bsc_subscr. Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no longer have a backpointer to gsm_network (used to be via subscr->group). Create a separate logging filter for the new BSC subscriber. The implementation of adjusting the filter context is added in libbsc to not introduce bsc_subscr_get/_put() dependencies to libcommon. During Paging Response, fetch a bsc_subscr from the mobile identity, like we do for the gsm_subscriber. It looks like a duplication now, but will make sense for the VLR as well as for future MSC split patches. Naming: it was requested to not name the new struct bsc_sub, because 'sub' is too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast to type, relatively short, unambiguous, and the naming is consistent. Add bsc_subscr unit test. Related: OS#1592, OS#1594 Change-Id: Ia61cc00e8bb186b976939a4fc8f7cf9ce6aa3d8e
2017-02-24cosmetic: rename osmo_msc_data.h to bsc_msc_data.hNeels Hofmeyr1-1/+1
With the OsmoMSC program coming up, the name osmo_msc_data becomes even more confusing than it already is. Clearly indicate it as libbsc's data of a remote MSC by prefixing with bsc_. Also, the Osmocom community has in the meantime agreed to have the osmo_ prefix only in libosmocore, to avoid naming conflicts in case things are moved there. So while renaming anyway, also drop the osmo_ prefix. Change-Id: I13554563ce9289de126ba0d4cf329bafcda35607

2017-02-08vty: remove ignored logging parametersMax1-2/+2
Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores parameters to log_vty_command_* functions. Hence parameter of logging_vty_add_cmds() is ignored too. As we depend on much later libosmocore version anyway, we can simplify code somewhat by removing parameters which will be ignored anyway. Change-Id: I62f752fd88f1d8fefa563648f9864c7c31f87991

2017-01-26Implement VTY configuration to control Early Classmark SendingHarald Welte1-0/+24

2016-12-02Move timezone settings up to network levelNeels Hofmeyr1-32/+33
Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS structures will be available on the MSC level. To simplify, drop the ability to manage several time zones in a core network and place the time zone config on the network VTY level, i.e. in gsm_network. If we are going to re-add fine grained time zone settings, it should probably be tied to the LAC. Adjust time zone VTY config code (to be moved to libcommon-cs in subsequent commit). Adjust time zone Ctrl Interface code. Change-Id: I69848887d92990f3d6f969be80f6ef91f6bdbbe8

Keep only BSC specific bits of the 'network' VTY node in bsc_vty.c, move more general VTY commands to common_cs_vty.c. Add arg to common_cs_vty_init() to pass a config_write_net() function. Pass a libbsc specific config_write_net() function. Future: upcoming omso-cscn will re-use the VTY bits moved to libcommon-cs and pass a different config_write_net() function.

Move gsmnet_from_vty() and the bsc_gsmnet global to common_cs_vty.c. Rename bsc_gsmnet to vty_global_gsm_network and make it static to common_cs_vty.c, to clearly mark the global variable for VTY use only. Introduce common_cs_vty_init() to set vty_global_gsm_network.

2016-11-03bsc_vty: include dyn TS info in vty show lchanNeels Hofmeyr1-3/+53
Extend both 'show lchan <bts> <trx> <lchan>' and 'show lchan summary' to include information on dynamic timeslots. Have one common function that prints " as foo" or " switching foo -> bar" to the vty, use it in lchan_dump_full_vty() and lchan_dump_short_vty(). In lchan_dump_short_vty(), split the vty_out call in two in order to interleave the dyn ts info right after the pchan. The summary hence looks e.g. like this for osmocom style dyn ts: BTS 0, TRX 0, Timeslot 5 TCH/F_TCH/H_PDCH as PDCH, Lchan 0, Type NONE, State ACTIVE - L1 MS Power: 0 dBm RXL-FULL-dl: -110 dBm RXL-FULL-ul: -110 dBm or BTS 0, TRX 0, Timeslot 4 TCH/F_TCH/H_PDCH switching NONE -> PDCH, Lchan 0, Type NONE, State BROKEN UNUSABLE - L1 MS Power: 0 dBm RXL-FULL-dl: -110 dBm RXL-FULL-ul: -110 dBm Change-Id: I3eb72ac7f0a520a8eefe171b9fb357f149aa3fda
2016-09-28Revert "bts: extend bts_chan_load to allow counting tch only"Neels Hofmeyr1-1/+1
This reverts commit 308cb0719dca3ba8eed1eff2a2124d44f34d9a28. Problems in this commit: openbsc/src/libbsc/chan_alloc.c:523: case GSM_PCHAN_TCH_F_PDCH: This is actually wrong, GSM_PCHAN_TCH_F_PDCH use ts->flags, not ts->dyn below (due to historical reasons and could be unified). 560: if (only_count_tch && !chan_is_tch(ts)) This has exactly one effect: it excludes GSM_PCHAN_TCH_F_PDCH when in PDCH mode, because for all other PDCH (plain PDCH and TCH/F_TCH/H_PDCH in PDCH mode) below ts_subslots() returns 0 and skips the for() loop. I consider this a bug in TCH/F_PDCH, to be fixed in an upcoming commit. I don't see why we need the only_count_tch argument, because this should normally only count TCH, weren't it for the TCH/F_PDCH bug. If dyn TS should be counted differently, we should do this in a different way. Change-Id: I34dbbaf53a800115e3d03bd44028cad675f3b525

If IMSI match the regexp than MS is allowed to access the network. If subscriber is already marked as authorized in HLR than it'll be allowed regardless of IMSI matching. The same way we can decide whether to create subscribers on-demand basesd on IMSI regexp match. Similar to authorization this restriction can be overridden by manually creating subscriber via vty, ctrl interface or directly in HLR.
