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 (6935e904ed0d76081ac26eebe7639ebb06ee8fa5)
             N -- N -- N (933fbe22c6679ea28730969f65abce438be31ad9)

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.

commit 099e36f03d7aa09220d9c79651f66a727cdd6be1
Author: Neels Hofmeyr <nhofmeyr at>
Date:   Tue May 10 13:28:18 2016 +0200

    move to libxsc: factor out gen of USSD notify and release complete -- TODO subscr_conn
    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.
    Future: both libbsc and libmsc will want to use the gsm0480_send_* functions,
    but using different subscriber connection structs. Hence move out the message
    generation guts and code-dup only thin shims to libbsc and libmsc.

    gsm_04_08: remove apply_codec_restrictions()
    This function is wrongly placed on the MSC level.
    Unfortunately I cannot remember the very plausible details that hwelte had
    back in the days to argue for this change. (Refactoring an old commit that
    fails to explain in more detail.)

    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.

    Move timezone settings up to network level
    Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS
    structures will be available on the MSC level. To simplify, drop the ability to
    manage several time zones in a core network and place the time zone config on
    the network VTY level, i.e. in gsm_network. If we are going to re-add fine
    grained time zone settings, it should probably be tied to the LAC.
    Adjust time zone VTY config code (to be moved to libxsc in subsequent commit).
    Adjust time zone Ctrl Interface 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.

    move to libxsc: 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 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 such callers 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.

    Put mncc_recv_cb_t in xsc.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 xsc.h (future knowledge). 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.

    gprs_gmm: Fix bit mask when determining update/attach type
    Bit 4 is reserved in 3GPP TS 04.08 so exclude it from the type.
    In 3GPP TS 24.008 it indicates if a follow-on request is pending by the
    MS, but only in Iu mode. According to the spec it is not required to
    react to that request with a follow-on proceed so this field can be
    ignored for now.
    See 3GPP TS 24.008 Ch. 4.4:
    "Unless it has specific permission from the network (follow-on proceed)
    the mobile station side should await the release of the RR connection
    used for a MM specific procedure before a new MM specific procedure or
    MM connection establishment is started."
    as well as Ch.
    "If the network wishes to prolong the RR connection to allow the mobile
    station to initiate MM connection establishment (for example if the
    mobile station has indicated in the LOCATION UPDATING REQUEST that it
    has a follow-on request pending) the network shall send "follow on
    proceed" in the LOCATION UPDATING ACCEPT and start timer T3255."

    osmo-sgsn: add libiu and libasn1c, libosmo-sigtran, libosmo-ranap
    The build will actually break until libiu is used by osmo-sgsn in a subsequent
    commit, because so far libiu is skipped by the linker, and thus at least
    talloc_asn1_ctx and asn1_xer_print are missing for libosmo-ranap.
    Add asn_debug impl ("extern" from libasn1c).

    gprs_gmm.c: Perform LLME operations only if we have one
    In case the GMM message did not arrive over a Gb interface, there is no
    LLME (and thus the associated pointer is NULL).  Don't try to perform
    operations on a NULL LLME.

    gprs_gmm.c: Make TLLI handling specific to Gb interface
    Soem of the operations we perform in the GMM layer are specific to the
    GPRS/EDGE radio access network and its Gb interface.  Let's make them
    conditional to that in preparation of supporting an Iu interface.

    gprs_gmm.c: Don't try to de-reference NULL mmctx
    There was a comment in the code that certain GMM messages require a
    valid mmctx pointer.  However, nothing actually checked if that pointer
    was in fact non-NULL.  We plainly crashed if a MS would send us the
    wrong message in the wrong state.
    Original patch by Harald Welte, but it broke message validity checking,
    resulting in sgsn_test failure. This re-implements the NULL check in a
    different way, as explained by in-code comment.
