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 (758c6c478d787a59983c80896c4fabb69b679fd1) \ N -- N -- N (4e380dc32315f378fecd359ec666f5e0a9639f33) 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=4e380dc32315f378fecd359ec666f5e0… commit 4e380dc32315f378fecd359ec666f5e0a9639f33 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 2 20:39:17 2017 +0100 wip Change-Id: Ife95dfebe4cea20bb61c9216991e964b2d51d07b http://cgit.osmocom.org/openbsc/commit/?id=32cdcebdc84b620f5af681dd43f526d3… commit 32cdcebdc84b620f5af681dd43f526d39532e841 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 2 02:37:39 2017 +0100 wip Change-Id: I4101b102145a011cec1eb8b92863f38ff7db57b2 http://cgit.osmocom.org/openbsc/commit/?id=6094dd282e6c35ca7e7792e793e564d2… commit 6094dd282e6c35ca7e7792e793e564d27c588a79 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Thu Mar 2 02:22:58 2017 +0100 mark fixme: rate counters Change-Id: I45651fd4cf3f4da8ad67251bbb3b627888e76d9c http://cgit.osmocom.org/openbsc/commit/?id=5afbec9502e32e93dcf2778ca9f4d031… commit 5afbec9502e32e93dcf2778ca9f4d031a7a1be57 Author: Neels Hofmeyr <nhofmeyr(a)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=4e3123bd1adb95a62cb0bee68b79692b… commit 4e3123bd1adb95a62cb0bee68b79692b291751fc Author: Neels Hofmeyr <nhofmeyr(a)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=ff41dece6e4a1d9969336af7db5dcac3… commit ff41dece6e4a1d9969336af7db5dcac3dd918114 Author: Neels Hofmeyr <nhofmeyr(a)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=99cc75d94be980f0a1663ffb585de4cc… commit 99cc75d94be980f0a1663ffb585de4ccbae94033 Author: Neels Hofmeyr <nhofmeyr(a)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=f08c91d8f91ec23a6b7ab5faee0e39f6… commit f08c91d8f91ec23a6b7ab5faee0e39f6d5150011 Author: Neels Hofmeyr <nhofmeyr(a)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=faaeab07dabcf2e3c3f347eb2cce6268… commit faaeab07dabcf2e3c3f347eb2cce626896649e94 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=b0cbedc45df75e5a64cc952340098f96… commit b0cbedc45df75e5a64cc952340098f96e99bfbff Author: Neels Hofmeyr <nhofmeyr(a)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.

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.

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. Instead, count Location Updating results, i.e. completion and failures. http://cgit.osmocom.org/openbsc/commit/?id=3c33cf8f698850766f28a5ded8150153… commit 3c33cf8f698850766f28a5ded8150153a9f530cf 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=c53d824e04af21eb2412229ee02e38d3… commit c53d824e04af21eb2412229ee02e38d3bf8c4ad7 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.

Introduce a new state COMMUNICATING, so that the ACCEPTED state can timeout. COMMUNICATING starts as soon as the MS first replies with a message for CC, SMS or USSD negotiation. The CC/SMS/USSD code is then expected to handle timeouts and BUMP the conn_fsm as appropriate. Add new test in msc_vlr_test_ms_timeout.c to verify that a CM Service Request and Paging Response without replies from the MS time out. Explicitly test for the COMMUNICATING state in msc_vlr_test_no_authen.c, but in the other tests just rely on the test output validation to ensure that the new state is entered in the right places.

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.

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.

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.

Have two distinct VTY commands and fix documentation. Put the asn_debug and asn1_xer_print implementations in iu.c. 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 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.

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).

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=1d5f0f50f28d03f813def41d605a75d0… commit 1d5f0f50f28d03f813def41d605a75d09a5557eb 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=a0928566ae0cefa0f16b39d2fa518d99… commit a0928566ae0cefa0f16b39d2fa518d991272c007 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.

The probability that a subscriber would be able to take unauthorized action is slim, nevertheless checking authorization status with the database should happen before we accept a connection. http://cgit.osmocom.org/openbsc/commit/?id=771d3bb82f60cd18c5d6f1c24f9c4e9b… commit 771d3bb82f60cd18c5d6f1c24f9c4e9bf87f8662 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:55:22 2016 +0200 paging: change subscr_paging_cb() into subscr_rx_paging_response() Remove one layer of callback indirection in paging. 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.

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.

Introduce a new state COMMUNICATING, so that the ACCEPTED state can timeout. COMMUNICATING starts as soon as the MS first replies with a message for CC, SMS or USSD negotiation. The CC/SMS/USSD code is then expected to handle timeouts and BUMP the conn_fsm as appropriate. Add new test in msc_vlr_test_ms_timeout.c to verify that a CM Service Request and Paging Response without replies from the MS time out. Explicitly test for the COMMUNICATING state in msc_vlr_test_no_authen.c, but in the other tests just rely on the test output validation to ensure that the new state is entered in the right places.

Clean up all pending trans when the conn is closed, to prevent segfaults.

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).

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.

Prepares for Iu, but also for libvlr to decide between GSM or UMTS Auth. Until actual Iu support is merged to master, this indicator will aid VLR unit testing. At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to clearly distinguish the names if we want to add it, explicitly name the ones we have RAN_GERAN_A and RAN_UTRAN_IU.
