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 (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

    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.

    IuCS, IuPS: move flag to use X.213 NSAP addr into ue_conn_ctx
    
    The future perspective is to remember the preferred RAB Transport Layer Address
    encoding for each 3G cell that is connected, so store per UE conn instead of
    globally hardcoding.
    
    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.

    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.

    iu: sort out confusion around asn_debug and asn1_xer_print
    
    Before, I confused asn_debug with asn1_xer_print. 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.

    IuCS: rapidly release connections
    
    Do the same as we do in 2G: release the connection as soon as nothing else
    is pending for a given subscriber.
    
    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.

    IuCS: don't remove Iu conn until release
    
    Don't remove the gsm_subscriber_connection without an Iu Release.
    
    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.

    IuCS: implement msc_call_assignment() for IuCS
    
    Send IuCS RAB Activation upon MNCC_CALL_PROC_REQ.
    
    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

    libmgcp: add mgcpgw client API
    
    Add an API to send MGCP messages to an MGCP GW, from the perspective of
    an MSC instructing the GW to setup RTP streams.
    
    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).

    IuCS: send RANAP CommonID
    
    Add libiu function to send a CommonID message down a UE connection,
    iu_tx_common_id(); add also a corresponding stub to libiudummy for linking with
    tests.
    
    Add libmsc function msc_tx_common_id() to call the above. Add this mostly to
    clearly indicate in msc_ifaces.h that libmsc is calling out of the MSC; also
    to do conn->via_iface checking.
    
    Call msc_tx_common_id() after ciphering is established, in
    _gsm48_rx_mm_serv_req_sec_cb()'s GSM_SECURITY_SUCCEEDED case.

    LU counters: count completion and failure, not messages sent
    
    From a human admin viewpoint it doesn't make sense to count the messages sent:
    
    When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect
    the MS to respond with a TMSI Realloc Complete message. 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.

    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. So, after all pending requests have
    been discarded, also discard and free the unused connection.

    complete IuCS paging implementation
    
    Add paging timeout to struct gsm_subscriber. Previously, paging timeout was
    implemented only on BSC level, where each request has its own timeout value.
    The MSC will still send individual requests to BSC or RNC level, where they
    timeout individually. However, the MSC must also have an own timeout to be sure
    to discard stale pagings that the BSC or RNC never replied for.
    
    Add handle_paging_resp(), copying the few libmsc relevant parts of
    gsm48_handle_paging_resp().

    paging: actually verify subscriber authorization
    
    Before this, any paging response would be accepted by the CN, without
    checking the database whether the subscriber is in fact authorized.
    
    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.

    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.

    cut off libbsc paging, pending paging in libmsc
    
    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.

    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 relatd to msc_gsm0808_tx_cipher_mode() in two places.

    gsm_04_08, gsm_subscriber: decouple lac from bts
    
    The idea is to not have a direct pointer to a bts struct (into BSC land), but a
    LAC to resolve the BSC or RNC depending on the appropriate A or IuCS interface.
    
    subscr_update(): remove bts arg, add lac arg.
    
    Pass conn->lac to gsm48_generate_lai() instead of bts->location_area_code.

    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]").

    conn timeout: implement conn_fsm COMMUNICATING state
    
    When in the ACCEPTED state, if the MS never sent any message, the conn would
    stay open indefinitely. 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.

    fix segfault: when a conn is closed, clean up its trans
    
    From conn_fsm timeouts, it is possible that a subscriber connection gets
    discarded even though e.g. an SMS gsm_trans is still in the queue. Clean up all
    pending trans when the conn is closed, to prevent segfaults.

    vlr: get SMS working, by SMS recipient MSISDN round-robin
    
    The SQL based lookup of SMS for attached subscribers no longer works since the
    SQL database no longer has the subscriber data. 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 subscriber_connection ref-counting
    
    This introduces a reference count for gsm_subscriber_connection. 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).

    add struct bsc_subscr, separating libbsc from gsm_subscriber
    
    In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will
    not make sense to use vlr_subscr in libbsc. 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.
