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 (7e7624cd5be3049b53d6e6735928281aa03bff68)
            \
             N -- N -- N (dd0659326ebbd4a9a2bdafbd9d3b9d6b492d851b)

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.

    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-cscn 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-cscn and
    osmo-sgsn. Add generic iu_vty_config_write() to write out the config.
    
    Call iu_vty_init() from cscn_vty_init(); cscn_vty_init() is in libmsc,
    hence linking of osmo-cscn 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.

    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-cscn 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-cscn 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-cscn 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: detect whether a conn is already secure
    
    If a CM Service Request is received on an already secure IuCS connection,
    we so far didn't notice and started to authenticate again. 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.

    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-cscn is going to use this to route RTP streams (for 3G at first).

    IuCS: cosmetic prep for msc_call_assignment()
    
    Rename gsm48_cc_tx_call_proc() to gsm48_cc_tx_call_proc_and_assign() to mark
    the place where the A-interface will send a BSSAP Assignment Request / where
    the IuCS-interface will send a RAB Assignment Request.
    
    Add function msc_call_assignment() to decide between A-iface and IuCS
    assignment, to be implemented in subsequent commit.

    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 CSCN is fully operational, paging will be controlled separately on
    the MSC level, and the BSC (RNC) level will be instructed over an IuCS or

    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.

    Pass conn->lac to gsm48_generate_lai() instead of bts->location_area_code.

    reinvent connection_for_subscr() and move to libmsc
    
    Implement connection_for_subscr() from a completely different angle: instead of
    looking up lchans in bts structs, look up the subscriber in the global list of
    gsm_subscriber_connection. static lchan_find() is thus obsoleted.
    
    All callers of connection_for_subscr() live in libmsc, so move to libmsc.
    
    The move and edit are done in a single commit since the old and new
    implementation have nothing in common.
    
    Future: osmo-cscn will use this, without bts being present.
    
    Remove implementation of connection_for_subscr() from channel_test.c -- it is
    possible that the abort() in there was intended for a regression test, but
    actually it seems the implementation was merely added for linking reasons, and
    the abort() added to guard against the NULL return value: no comment nor the
    commit log indicate that the abort() is test critical; the addition was the
    only change in channel_test.c for that commit; at the same time a
    connection_for_subscr() call was added in libmsc.

    global gsm_network: move allocation further up
    
    Now that bsc_network_alloc() is separate, move it to before the VTY init (a
    subsequent patch will pass the gsm_network instance as a parameter to
    vty_init()).
    
    bsc_hack.c: drop the comment that says about the VTY init: "This needs to
    precede handle_options()" -- it is not accurate. Actually move the
    handle_options() above both vty_init() and the bsc_network_alloc() calls, to be
    able to decide which mncc callback to pass to bsc_network_alloc. It would make
    sense to set this later on, but that would require further refactoring of the
    bsc_network_init() and gsm_network_init() signatures, so not in this patch.

    split bsc_bootstrap_network() in alloc and config
    
    For patch clarity, keep some code dup to be removed in a subsequent patch. In
    the same sense don't change the fact that mncc_sock_init()'s return value is
    ignored.
    
    The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY,
    and a future patch will "hide" that global in a vty .c file. In a nutshell, I
    want to
    
    - first allocate a gsm_network,
    - then initialize the VTY passing the gsm_network pointer,
    - and then read the config file using the initialized VTY.
    
    So far, bsc_bootstrap_network() allocates the gsm_network and reads the config
    file right away, which only works by sharing the extern bsc_gsmnet pointer,
    which I would like to uncouple.

    tests: drop unused libmsc, unneeded duplicate libbsc linking
    
    Because of libcommon-cs, tests/gsm0408,subscr,trau no longer need libmsc.

    sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counter
    
    libbsc and libmsc will have separate subscriber connection structs. 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.

    move to libcommon-cs: factor out gen of USSD notify and release complete
    
    Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and
    gsm0480_send_releaseComplete() functions, since there will be distinct
    subscriber connection structs.
    
    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 libcommon-cs.

    move to libcommon-cs: gsm48_create_mm_serv_rej(), gsm48_create_loc_upd_rej()
    
    Used by libbsc, libmsc as well as osmo-bsc and osmo-bsc_nat.
    
    Moving gsm48_create* to libcommon-cs affects linking of osmo-bsc_nat, resulting in
    undefined references to gsm48_extract_mi() and gsm48_paging_extract_mi(); fix
    that by placing libfilter.a left of libbsc.a upon linker invocation.

    move to libcommon-cs: net init 3: actual move
    
    Reincarnate gsm_network_init() as the parts not specific to libbsc.
    Move from bsc_network_init() those bits that are not BSC specific (and useful
    for upcoming osmo-cscn).
    
    Add libcommon-cs 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 libcommon-cs. The other items
    are kept out of libcommon-cs 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.

    move to libcommon-cs: net init 1: rename to bsc_network_init
    
    The gsm_network_init() function initializes a whole lot of BSC specific stuff.
    Aiming to move some of it to libcommon-cs, 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.

    define mncc_recv_cb_t to avoid code dup
    
    Put mncc_recv_cb_t in common_cs.h to avoid header include complications: if placing
    right above struct gsm_network, one must include gsm_data.h to use
    mncc_recv_cb_t as function parameter in a header, which will include
    gsm_data_shared.h, which will include common_cs.h (future knowledge). Since I will
    need to use mncc_recv_cb_t in common_cs.h, including gsm_data.h from there would
    introduce an #include loop. Avoid that and define mncc_recv_cb_t in common_cs.h to
    begin with.
