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 (c14a3978c2b5aa476a698b4281ffbfb5778c11b2) \ N -- N -- N (5859963b3483f7bd584c659668e3e8046d676b23) 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=5859963b3483f7bd584c659668e3e804… commit 5859963b3483f7bd584c659668e3e8046d676b23 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 9 16:51:58 2017 +0100 vlr: allow setting assign_tmsi per-subscriber Change-Id: I7469da0ed19e1e8b292422aadfd3ae2ebc2afd57 http://cgit.osmocom.org/openbsc/commit/?id=83b33695d9628fb322c4d58a3e8ed48f… commit 83b33695d9628fb322c4d58a3e8ed48fc7c3a418 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 30 15:09:47 2016 +0200 temporary dev: set debug log level almost everywhere Change-Id: I0d5a36560e7edde27497de57e579f5b1d00eb525 http://cgit.osmocom.org/openbsc/commit/?id=72623354fb7eb13d1508e6447e90f70d… commit 72623354fb7eb13d1508e6447e90f70d9febf606 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Fri Mar 10 02:15:20 2017 +0100 log protocol discriminators and message types by name Depends: libosmocore change-id I0fca8e95ed5c2148b1a7440eff3fc9c7583898df Change-Id: If1c49faf6e1757cb16b383dd2db87b48bc94eee6 http://cgit.osmocom.org/openbsc/commit/?id=b428e7692a98a48de90a370597fa2ce1… commit b428e7692a98a48de90a370597fa2ce135eda83b Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 16 16:14:34 2017 +0100 mgcp: hack RAB success from nano3G: patch first RTP payload The ip.access nano3G needs the first RTP payload's first two bytes to read hex 'e400', or it will reject the RAB assignment.

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.

When that fails to come through, the LU actually ends in failure, even though a LU Accept was sent. In 3G, if a UE sends an Iu Release during LU (e.g. user enables flight mode), we cancel the LU without sending any reply at all, so nothing would be counted. Instead, count Location Updating results, i.e. completion and failures. http://cgit.osmocom.org/openbsc/commit/?id=a81fbf00918e742d9a4f5ac47eca8759… commit a81fbf00918e742d9a4f5ac47eca875918043c2f Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Wed Oct 12 02:53:55 2016 +0200 IuPS: cosmetic: explicitly check RAN type; move comment Change-Id: I8375ba42dd47d7ccd9ce9290767d6f8653a23b94 http://cgit.osmocom.org/openbsc/commit/?id=7a4632c67cd6abe114d4c4094272b749… commit 7a4632c67cd6abe114d4c4094272b7493cd3c57a Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Wed Oct 12 03:30:48 2016 +0200 sgsn init: pass sgsn_config pointer to sgsn_vty_init(), not sgsn_parse_config It makes sense semantically, and prepares for an upcoming commit that uses the internal global config pointer in sgsn_vty_init(), which would not be defined yet without this.

The unit test didn't catch that because its fake HLR message contained only one tuple. Adjust the test to send two tuples to catch this error. Fix the code to clear vlr_subscr->last_tuple whenever new auth tuples are received.

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.

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.

Every user of the connection needs to hold a reference until done. Once the reference count dorps to zero, the connection is cleared towards the BSC (which subsequently will clear any logical channels associated with it).
