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 (dd15d7cf6c51f254c8356fca8dd47af000bc8cab)
             N -- N -- N (4193f174dd6cdaabf2d4319faec463261a37d5af)

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.

    sgsn: Added TODOs (TODO)
      - fix and remove TODOs
      - add test cases for Detach(reattach)
      - add test cases for PDP context deletion (OW#1311)
      - add test cases for Cancel pending timer in sgsn_mm_ctx_free
      - remove this commit

commit 95f84db2402d458fd5b3d899f08cb33ec9cd3212
Author: Jacob Erlbeck <jerlbeck at>
Date:   Tue Nov 4 12:44:15 2014 +0100

    sgsn: Notify an affected MM context if an ACL rule is removed (TODO)
    Currently if an ACL access rule is removed, MS already attached are
    not affected until they try to reattach to the SGSN.
    This patch adds sgsn_auth_update_all() that iterates through allMM
    contexts and calls sgsn_auth_update() on each of them. This function
    is then called when 'imsi-acl del IMSI' is executed after the ACL has
    been removed.
     - decide, whether ito replace that by a dedicated update command in
       the VTY ENABLE node

    sgsn: Do not die in _bssgp_tx_dl_ud on TLLI mismatch (TODO)
    Currently an OSMO_ASSERT fails, if the message's and the mmctx's
    TLLIs do not match.
    This commit turns the assertion into an ERROR log message and uses
    the default values for IMSI, DRX, and RA CAP instead of the MM
    context values in this case.
      - find the real source for the problem
      - add test cases derived from what is being described in the ticket
    Ticket: OW#1322

    sgsn: Add VTY commands to manage subscriber cache
    This adds the following commands to the ENABLE node:
      - show subscriber cache
      - update-subscriber imsi IMSI insert authorized (0|1)
      - update-subscriber imsi IMSI cancel
    These commands are mainly testing tools and maintenance helpers. The
    update commands work asynchronously and can be used to complete a
    pending update request or to terminate an existing connection.
    Note that the subscriber cache is not stored persistently and will
    always be empty after an SGSN restart.

    sgsn: Add gsm0408_gprs_access_cancelled (TODO)
    This function is called to delete an established MM context
    without invoking a detach procedure that could disable the GPRS
    functionality of the MS until the next power cycle.
    It is called when a subscriber is cancelled.

    sgsn: Integrate subscriber handling into the SGSN (TODO)
    This commit adds a new authorization policy 'remote' and uses
    the subscriber cache for authorization when this policy is being used.
    Note that there is no remote backend implemented yet.
     - tests
     - decide, whether 'remote' could be named better, e.g. sth based on

commit a374e69d392dc4cfccf7a367c74961b2786bbc90
Author: Jacob Erlbeck <jerlbeck at>
Date:   Wed Nov 12 10:12:11 2014 +0100

    sgsn: Add gprs_subscriber.c
    This patch adds GPRS specific functions for gsm_subscriber objects
    (allocation, retrieval, deletion) and subscriber data
    requests/updates. The sgsn_update_subscriber_data callback is used to
    notify the sgsn about updates and is extended by a parameter that
    passes a reference to a gsm_subscriber.
