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 (cbfe8ef90a319af5d79b9daf71d2b9b7724b6b8e)
            \
             N -- N -- N (72b54994d68d89ff2cccf3e113d92ebbe0f7ca17)

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: Send PING and eventually reconnect
    
    Currently, the reconnect mechanism relies on gsup_client_updown_cb
    which in turn gets called based on the OS' view of connection state.
    
    This patch adds a timer based PING mechanism that regularly sends
    PING messages and forces a reconnect if a PONG message won't be
    received until the next PING message is scheduled. The current ping
    interval is 20s.

commit 8efcafd1bd5f825d2e88c8e0ded1e16e9107ca6b
Author: Jacob Erlbeck <jerlbeck at sysmocom.de>

    sgsn: Handle incoming IPA CCM message in gsup_client_read_cb
    
    Currently the IPA CCM messages are not handled by the GSUP client.
    This means, that the client doesn't answer to PING and ID_GET and
    logs notices when receiving PONG or ID_ACK. At least the PING
    functionality (remotely originated PING) shall be supported.
    
    This patch extends gsup_client_read_cb by a call to
    ipaccess_bts_handle_ccm. Only when the return code is 0, the message
    is processed further and checked for an OSMO/GSUP message. ID_GET
    messages are answered by a dummy description, where only the
    unit_name is set to 'SGSN'.

Author: Jacob Erlbeck <jerlbeck at sysmocom.de>
Date:   Fri Dec 19 19:00:56 2014 +0100

    sgsn: Handle return code of ipa_client_conn_open correctly
    
    The ipa_client_conn_open function does not distinguish between a
    connection being already established or waiting for establishment.
    In either case, the application gets informed about the connection
    state via the updown_cb. The 'up' parameter is only set, if
    poll/select consider the socket as writable.
    
    This patch handles both cases equally and fully relies on the
    updown_cb to adjust the gsupc obejct state.

commit cebc8b091949338b11c69b0d5ec090bc80773ac5
Author: Jacob Erlbeck <jerlbeck at sysmocom.de>
Date:   Fri Dec 19 18:50:05 2014 +0100

    sgsn: Avoid sending stale GSUP requests after reconnect
    
    Currently, messages are added to the tx queue even if the connection
    is down for some reason and all of these messages are eventually sent
    after a re-connect.  The MS has probably sent several Attach Requests
    while the connection was down and will continue doing so. Therefore
    these stored messages could be dropped.
    
    This patch clears the queue before re-connecting and also extends
    gprs_gsup_client_send to return immediately, when the connection is
    not established instead of calling ipa_client_conn_send.

commit e70c27ff1174bd43c95ce1f18e64b7ced20889f7
Author: Jacob Erlbeck <jerlbeck at sysmocom.de>
Date:   Thu Dec 18 15:00:29 2014 +0100

    sgsn: Add automatic re-connect if the GSUP connection is down
    
    Currently the GSUP connection to a server is not restarted if the
    connection cannot be established or is terminated during operation.
    
    This commit adds a timer based connection mechanism, basically
    consisting of a timer callback that calls gsup_client_connect. The
    timer is eventually triggered (up == 0) or cleared (up != 0) by
    gsup_client_updown_cb. It adds calls to osmo_timer_del() to
    gsup_client_connect and gprs_gsup_client_destroy. The latter is now
    called instead of talloc_free in gprs_gsup_client_create on error to
    be on the safe side.

    sgsn/test: Extend tests to simulate lost GSUP requests
    
    This patch extends test_gmm_attach to optionally resend Attach
    Requests until the SGSN responds to it instead of calling
    OSMO_ASSERT at a few places. The test_gmm_attach_subscr_gsup_auth
    test optionally uses this feature. It is called once in either mode.

    This patch replaces that flag by a global cfg.require_authentication

    every subscriber. The flag is set by the VTY, if and only if the
    authorization policy is 'remote'.

      - update-subscriber imsi IMSI insert authenticate <0-1>
    
    is removed.
