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 (b829af3332a9c22ee6ecdf9eb38ae491ba2b5372)
             N -- N -- N (88fc20c7ed1cc5e6db40e930e3079d77bbc10d70)

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 fae2eb23be1fe3aff2540b44e21f54953dcad270
Author: Daniel Willmann <dwillmann at>
Date:   Mon Jan 25 16:49:53 2016 +0100

    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).

    sgsn_mm_ctx_cleanup_free(): clean up LLME iff present (Gb, not Iu)
    Assert that llme is unused for non-Gb (Iu) connections, and clean up otherwise.
    Make sure the cleanup is left below the sgsn_mm_ctx_free() call, as the comment

    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.

    rename gsm0408_gprs_rcvmsg() to gsm0408_gprs_rcvmsg_gb()
    This is the entry point for GMM from Gb.  We will create a new one
    for Iu, so let's be explicit rather than implicit.
