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 (102ed77e45d3146bf9f0d293819df8c4fe6e37d7) \ N -- N -- N (de0cd696cf5af9a42a79ca5bd6d639f9259b351f) 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=de0cd696cf5af9a42a79ca5bd6d639f9… commit de0cd696cf5af9a42a79ca5bd6d639f9259b351f Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Sep 26 02:24:53 2016 +0200 CID 148863 Change-Id: I4c5d9ff7dcf1532bbfce137c552ccd768412b17b http://cgit.osmocom.org/openbsc/commit/?id=a2eee43b4b271c0eab8d25af824a5c39… commit a2eee43b4b271c0eab8d25af824a5c39138f1291 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon Apr 25 15:40:54 2016 +0200 RAB Assignment: IuPS + IuCS: use shorter 32 bit IP address format This is needed for the ip.access nano3G femto cell.

Implement function msc_call_assignment(): decide between sending A-iface BSSMAP Assignment Request or IuCS RAB Assignment Request. Implement iu_rab_act_cs() to send the IuCS RAB Assignment Request. The IP address and port of the MGCPGW sent in the RAB Assignment are still hardcoded. The A-interface extension is not implemented yet. Declare ranap_new_msg_rab_assign_voice() to avoid including ranap_msg_factory.h, which would require adding ASN1 CFLAGS to Makefile.am. The mgcpgw_client as well as some more osmo-iuh functions are now linked from libmsc, hence add some dummy stubs to libiudummy and db_test.c.

The mgcp_protocol.h is mostly for the MGCP GW itself, other implementations forward incoming MGCP messages. So a simpler approach for an MGCP GW client is useful. osmo-cscn is going to use this to route RTP streams (for 3G).

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=5929d9c9520f6686b8c54746c6786615… commit 5929d9c9520f6686b8c54746c6786615ef141f65 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 30 15:21:52 2016 +0200 remove handle_abisip_signal() Change-Id: I9cf80f9c2c8a53a29e42f000029e680a9922cb41 http://cgit.osmocom.org/openbsc/commit/?id=eee41f1b7b554264e7dfaf0c913d3a88… commit eee41f1b7b554264e7dfaf0c913d3a88fac5126e Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Wed May 4 15:35:37 2016 +0200 gsm0408_clear_request(): actually free the released conn By having conn->in_release == 1, calling msc_release_connection() has no effect and thus never frees the conn.

When a paging response arrives, we always want to first secure the connection, thus a fixed subscr_rx_paging_response() function is more appropriate and avoids having to store a cbfn. The actual actions to be taken upon successful paging are of course still in callback functions stored with each subscriber. Remove paging_request_stop() call from subscr_paging_dispatch(), which stops paging on all BTSs, which is not the responsibility of libmsc.

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

Hence don't rely on gsm_subscriber_connection, but work on a direct pointer to the counter for the next RP reference. The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop the entire file.

The current functions live in libmsc, so add the same in libbsc in new file gsm_04_80_utils.c. To avoid too much code dup, move the message generation part of gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() to new functions gsm0480_gen_ussdNotify() and gsm0480_gen_releaseComplete(), placed in libxsc.

Move from bsc_network_init() those bits that are not BSC specific (and useful for upcoming osmo-cscn). Add libxsc to all linkages that use gsm_network_init(). Note: the only requirement to allow linking gsm_network_init() without libbsc is to keep the call to gsm_net_update_ctype() out of libxsc. The other items are kept out of libxsc because it makes sense semantically. But the separation is not strong in that the BSC specific data members are of course still omnipresent in struct gsm_network. If bsc_network_init() is not called, these are not initialized properly -- for now no users of uninitialized members exist. So this is just a first step towards a sensible split of the BSC and MSC gsm_network structs. The long term aim should be to have entirely separate structs with some common general items. http://cgit.osmocom.org/openbsc/commit/?id=da55fbd7593fa0fa617b576f799d8b04… commit da55fbd7593fa0fa617b576f799d8b04f34fa411 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Sat May 14 00:57:04 2016 +0200 move to libxsc: net init 2: move bsc_network_init decl to osmo_bsc.h bsc_network_init() is more fit to live in a BSC specific header.

Aiming to move some of it to libxsc, first rename it to bsc_network_init(). This will retain the BSC specific stuff when the move is done. Adjust all callers. Future: osmo-cscn will call the more generic part and not the BSC specific part.

Since I will need to use mncc_recv_cb_t in xsc.h, including gsm_data.h from there would introduce an #include loop. Avoid that and define mncc_recv_cb_t in xsc.h to begin with.
