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 (b27b963b644790c8c5893b99c146523779a25c80) \ N -- N -- N (66c5ad1bba04788be9b2ae139cc78b5b6a986658) 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=66c5ad1bba04788be9b2ae139cc78b5b6... commit 66c5ad1bba04788be9b2ae139cc78b5b6a986658 Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Fri Oct 21 01:32:10 2016 +0200 mgcp: log payload type change Change-Id: Iee5fa667dece12174b1933345c1ed640a264ed97 http://cgit.osmocom.org/openbsc/commit/?id=c4cd09995d4c18d95571ef198f97611ae... commit c4cd09995d4c18d95571ef198f97611ae0ac2bd5 Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Mon Jan 23 16:56:02 2017 +0100 comment: fixme: rab failure Change-Id: I6e21f2d7dd560ab15675f3e432c37a13c4ab6792 http://cgit.osmocom.org/openbsc/commit/?id=8ac4b7226b34cebe58c91fab029e31900... commit 8ac4b7226b34cebe58c91fab029e31900224b3e1 Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Tue Oct 18 20:20:51 2016 +0200 mgcp parsing, set port from mgcp response Change-Id: I90e2c1aa7575d5fa6e0374f5022cbb25fc3f7699 http://cgit.osmocom.org/openbsc/commit/?id=45341527600afe4a044b33130d281c662... commit 45341527600afe4a044b33130d281c6622351861 Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Tue Oct 18 18:38:59 2016 +0200 mgcp parsing, mgcp test Change-Id: Ibe2ab17b3fa3a506a2e841ba979ea4175e3a21e8 http://cgit.osmocom.org/openbsc/commit/?id=590a90534240ee2d8c2515db5687489fa... commit 590a90534240ee2d8c2515db5687489fade290fa Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Fri Oct 14 17:56:17 2016 +0200 mgcp: handle responses from the MGCP GW Change-Id: I5c0493feaec775461b5a017c36b93cc2ad63c896 http://cgit.osmocom.org/openbsc/commit/?id=84c1275aec91183c2205d5ec786903635... commit 84c1275aec91183c2205d5ec786903635507b4c5 Author: Neels Hofmeyr <nhofmeyr@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=2eec16ff27f701a6aef172aa7121153d0... commit 2eec16ff27f701a6aef172aa7121153d0021a27e Author: Neels Hofmeyr <nhofmeyr@sysmocom.de> Date: Wed Oct 12 01:39:25 2016 +0200 IuCS and IuPS: add VTY config for RAB Assignment address kind To accomodate the ip.access nano3G without having to recompile, make the RAB Assignment's Transport Layer Address IE's format configurable, in both osmo-msc and osmo-sgsn. The long term perspective is to somehow detect which address encoding a given 3G cell prefers, but for the time being just configure it globally and set each ue_conn_ctx to the global setting upon creation. Add VTY command to iu_vty.c, with args passed to iu_vty_init() to insert at an arbitrary VTY node, so that it can be used both for osmo-msc and osmo-sgsn. Add generic iu_vty_config_write() to write out the config. Call iu_vty_init() from msc_vty_init(); msc_vty_init() is in libmsc, hence linking of osmo-msc now needs libiu to come after libmsc, so move that further down.

Add rab_assign_addr_enc member to ue_conn_ctx. Thus the iu_rab_act_cs() and iu_rab_act_ps() functions no longer need the explicit use_x213_nsap argument. Add include/openbsc/common.h in order to define the enum nsap_addr_enc, in a separate file to be able to easily include it in all of libmsc, libiu and gprs/* without creating include cycles. Set the rab_assign_addr_enc when an MM ctx is created for iu, and whenever the ue_conn_ctx for an Iu MM ctx is updated. This looks a bit clumsy so far, the hope is that there will be a nice way to setup the ue_conn_ctx prior to that.

Since they are globally defined, don't pass a pointer to iu_vty_init() but just use it directly. Might be considered less clean, but is also less bloat.

Before, osmo-msc would wait for the UE "to get bored" and send an Iu release. But the CN should stay lean on connections. Also, 25.413[1] in section 7, 6th point states: "While the Iu release is managed from the CN, the RNC has the capability to request the release of all Iu connection resources from the corresponding Iu connection." So far we did not manage Iu release from osmo-msc at all. Use the same mechanism we use in 2G: from msc_release_connection(), just before freeing the gsm_subscriber_conn, invoke a CN initiated Iu Release command to the UE. This works around OS#1816 ("USSD only works when IuCS is released", on nano3G), because the Iu conn is now released right after every signalling, so that typically no two requests will use the same conn. In iu.h/iu.c, add iu_tx_release(), absorbing almost all of the code from ranap_handle_co_iu_rel_req(). Add stub to db_test.c, necessary to build it without linking libiu.

From the 2G paradigm to close a subscriber connection as soon as nothing else is pending, osmo-msc frequently calls msc_release_connection() to see whether a conn has anything pending, or discards it. In 3G however, we so far don't actively release IuCS connections from the MSC side, but wait until the IuCS is released from the UE side. So the conn is often discarded even though the IuCS stays open and valid, which confuses the situation: before the UE releases a bit later, we would try to page the subscriber unsuccessfully, because the UE expects to already be connected. To first fix the discrepancy of Iu vs. subscr release, never discard gsm_subscriber_connections when msc_release_connection() is called. This creates a "lazy" CN that keeps connections open as long as the UE will tolerate. It is really fast in sending many SMS in close succession, but is certainly a bad CN design choice: we should rather stay lean on connections. A subsequent commit will change this, but I decided to keep this commit as a reference, for when we'd like to test situations that should re-use an established connection.

The UE would readily renew its authentication, but then our state got stuck since ciphering was already established. Instead, don't authenticate again when integrity protection is already established.

Rationale: 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. Add general VTY commands that can be used to configure mgcpgw_client. osmo-msc is going to use this to route RTP streams (for 3G at first).

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.

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.

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 via_iface marker to gsm_subscriber_connection with enum values IFACE_A and IFACE_IU so far. Add Iu specific fields in a sub-struct: 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]").

So let's avoid doing it twice, and avoid having more dependency of the MSC down into the lchan details.
