2f8b9d25f8428980e35ed8f8b2dc44324bc4566a (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (44b975a641c500c6d2ebdc7b7e3650ebba121d2d) \ N -- N -- N (51d2a33542064e8605302a22214f57f7886c703e) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=51d2a33542064e8605302a22214f57f7… commit 51d2a33542064e8605302a22214f57f7886c703e Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Mon Jun 12 19:09:43 2017 +0200 osmo-bsc: react on reset requests from MSC The bsc side currently can not receive reset commands from an MSC.

This is done before forcefully dropping the affected connection. This commit ports the feature to the new libosmo-sigtran implementation. NOTE: I do not know if this works and I also do not really understand how this is even possible. Sending an USSD notification would rquire the subscriber to be properly attached? When the MSC is lost this almost not possible since no backend to authenticate against is available. http://cgit.osmocom.org/openbsc/commit/?id=b64c23440e3f41c47269a3dc58ddddd7… commit b64c23440e3f41c47269a3dc58ddddd765f38c84 Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Mon Jun 12 13:22:59 2017 +0200 cosmetic: make function names in a_iface_bssap more expressive.

It also will not help against inconsitancies that may occour during runtime (e.g. an overheard DLCX during regular call teardown). This reverts commit b669ea94cb78fd9b56ee8dd9392538151349f8ba. http://cgit.osmocom.org/openbsc/commit/?id=7a36bbad99e4cdbd5c081a5db62663ac… commit 7a36bbad99e4cdbd5c081a5db62663aca3aee191 Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Mon Jun 12 11:39:41 2017 +0200 mgcp: Make sure endpoint is free on CRCX The MSC is aware of the assigned endpoints at all times, so it will not assign an occupied endpoint to someone else. However, if it has just restarted, there maybe lingering open endpoints. This patch introduces a fairly simple soultion. Before a new endpoint is seized (CRCX), a DLCX is send in advance. If the endpoint was still occupied with a dead connection, it will be freed. If it was free anyway, the DLCX will just have no effect. http://cgit.osmocom.org/openbsc/commit/?id=41c0e21364974d4dca2a28c3c70dec76… commit 41c0e21364974d4dca2a28c3c70dec76a1c9269e Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Thu Jun 8 17:22:07 2017 +0200 a_iface_bssap: clear lingering subscriber connections on reset When the BSC is vanishing, the subscriber connections will stay active until the MSC is instructed via tha A interface to clear the connections. Unfortunately, this will most likely not be the case because the BSC will most likeley have lost all its state and does not know about the old connections anymore. This patch fixes the problem by looping through the list with the active gsm subscriber connections and clearing them manually when the reset from the BSC is received. Only connections by the bsc who actually executes the reset are affected. Connections from other BSCs will not be touched. http://cgit.osmocom.org/openbsc/commit/?id=456d3c44d1adf0ffe0f9684f57bddf75… commit 456d3c44d1adf0ffe0f9684f57bddf7575479e5c Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Thu Jun 8 17:00:31 2017 +0200 cosmetic: fix typo http://cgit.osmocom.org/openbsc/commit/?id=9b5dee4e33fc432898ecfe490e28e074… commit 9b5dee4e33fc432898ecfe490e28e0748dea83c9 Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Thu Jun 8 15:36:14 2017 +0200 mgcp: make sure all endpoints are closed on startup If the MSC is crashing and restarting, it may leave some endpoints open.

The mgcpgw only has a limited amount of endpoint identifiers avaliable, this means we will run out of endpoints after only a few calls. This commit adds a mechanism to keep track of used endpoint identifiers so unused endpoint identifiers can be re-used http://cgit.osmocom.org/openbsc/commit/?id=b8012aad098444a83014d40a4a84b62a… commit b8012aad098444a83014d40a4a84b62a4be4c59a Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Thu Jun 8 12:21:07 2017 +0200 mgcp: use mgcp DLCX command to terminate endpoint after call is done Currently no DLCX command is sent to the mgcpgw when a call is over, this leaves the endpoint open. This means that the endpoint can not never be reused by other calls. This patch adds a DLCX that terminates the the endpoint when the call is done. http://cgit.osmocom.org/openbsc/commit/?id=188a804f6df55a66185054e664d6b3a9… commit 188a804f6df55a66185054e664d6b3a998e7a371 Author: Philipp Maier <pmaier(a)sysmocom.de> Date: Thu Jun 8 12:19:30 2017 +0200 mgcp: add DLCX command to mgcpgw client The mgcpgw client currently lacks support for DLCX.

Currently only a simple bool variable serves as a state holder. We set this variable to true when we receive the RESET-ACK message. Unfortunately no further checking is done.

The post communicated via the assignment request is now transmitted via RSL/IPACC to the BTS. The Response containing the RX-Port at the BTS side is communicated back to the MSC. Since we plan to add a private MGCPGW to each BSC, this has to be extended. Currently it only creates a direct connection to the BTS.

Don't set msg->lchan nor msg->dst. Don't use lchan in libmsc. Decouple lac from bts. Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication: Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to different interfaces depending on the actual subscriber connection. While iu_tx() is going to be functional fairly soon, the a_tx() is going to be just a dummy for some time (see comment). Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer and an indicator for the Integrity Protection status on Iu (to be fully implemented in later commits). Add lac member to gsm_subscriber_connection, to allow decoupling from bts->location_area_code. The conn->lac will actually be set in iu.c in an upcoming commit ("add iucs.[hc]"). move to libcommon-cs: gsm48_extract_mi(), gsm48_paging_extract_mi(). libmsc: duplicate gsm0808 / gsm48 functions (towards BSC). In osmo-nitb, libmsc would directly call the functions on the BSC level, not always via the bsc_api. When separating libmsc from libbsc, some functions are missing from the linkage. Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also add a _tx to gsm0808_cipher_mode(): * add msc_gsm0808_tx_cipher_mode() (dummy/stub) * add msc_gsm48_tx_mm_serv_ack() * add msc_gsm48_tx_mm_serv_rej() Call these from libmsc instead of * gsm0808_cipher_mode() * gsm48_tx_mm_serv_ack() * gsm48_tx_mm_serv_rej() Also add a comment related to msc_gsm0808_tx_cipher_mode() in two places. Temporarily disable all paging to be able to link libmsc without libbsc. Skip the paging part of channel_test because the paging is now disabled. In osmo-nitb, paging is done on BSC level and MSC level "at the same time". When the new MSC is fully operational, paging will be controlled separately on the MSC level, and the BSC (RNC) level will be instructed over an IuCS or A-interface to negotiate paging with the MS (UE). This MSC level paging does not yet exist and will be added in subsequent commits. msc_compl_l3(): publish in .h, tweak return value. Use new libmsc enum values for return val, to avoid dependency on libbsc headers. Make callable from other scopes: publish in osmo_msc.h and remove 'static' in osmo_msc.c add gsm_encr to subscr_conn move subscr_request to gsm_subscriber.h subscr_request_channel() -> subscr_request_conn() move to libmsc: osmo_stats_vty_add_cmds() gsm_04_08: remove apply_codec_restrictions() gsm0408_test: use NULL for root ctx move to libbsc: gsm_bts_neighbor() move to libbsc: lchan_next_meas_rep() move vty config for t3212 to network level (periodic lu) remove unneccessary linking from some tests remove handle_abisip_signal() abis_rsl.c: don't use libvlr from libbsc Change-Id: I9cf80f9c2c8a53a29e42f000029e680a9922cb41 http://cgit.osmocom.org/openbsc/commit/?id=fd01ea2b6a778b8f610203b8de38d167… commit fd01ea2b6a778b8f610203b8de38d1677d7f02ac Author: Harald Welte <laforge(a)gnumonks.org> Date: Mon May 2 08:34:57 2016 +0200 IuPS adjustments SGSN: Don't indicate GERAN in Iu mode PDP CTX ACT REQ to GGSN sgsn_ranap_iu_event: handle some events without valid MM context sgsn init: pass sgsn_config pointer to sgsn_vty_init(), not sgsn_parse_config IuPS: cosmetic: explicitly check RAN type; move comment Change-Id: I8375ba42dd47d7ccd9ce9290767d6f8653a23b94 http://cgit.osmocom.org/openbsc/commit/?id=4d8d3fed5daf7c342c773883a6611a2f… commit 4d8d3fed5daf7c342c773883a6611a2fb10a8ea6 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Wed Mar 29 15:17:55 2017 +0200 osmo-nitb: change default config file name to osmo-nitb.cfg Since the VLR development marks a move away from the 'openbsc' name, now is a good opportunity to also change the default config file name to the more accurate and obvious 'osmo-nitb.cfg'.

Replace with a round-robin on the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the subscriber is currently attached. If there are many SMS for not-attached subscribers in the SMS database, this will become inefficient: a DB hit returns a pending SMS, the RAM lookup will reveal that the subscriber is not attached, after which the DB is hit for the next SMS. It would become more efficient e.g. by having an MSISDN based hash list for the VLR subscribers and by marking non-attached SMS recipients in the SMS database so that they can be excluded with the SQL query already. There is a sanity limit to do at most 100 db hits per attempt to find a pending SMS. So if there are more than 100 stored SMS waiting for their recipients to actually attach to the MSC, it may take more than one SMS queue trigger to deliver SMS for subscribers that are actually attached. This is not very beautiful, but is merely intended to carry us over to a time when we have a proper separate SMSC entity. Introduce gsm_subscriber_connection ref-counting in libmsc.

This is a long series of development collapsed in one patch. The original history may still be available as branch neels/vlr_orig.

Pass explicit unit name from each gsup client user, so that OsmoMSC is "MSC" and OsmoSGSN is "SGSN". Hence the HLR can properly route the messages. Todo: also set some values instead of the zeros. Unrelated cosmetic change while editing the arguments: gsup_client_create()'s definition's oap client config arg name mismatched the one used in the declaration. Use oapc_config in both.
