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 (0e1f5ad735ca326c34fd7758e1f1304341eacde7)
\
N -- N -- N (85a3619c1ce96d9a81776b7e3776a952ee61fb54)
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: Integrate Auth & Ciph into gsm48_gmm_authorize
Currently the Authentication and Ciphering procedure is not yet
invoked by the GMM layer.
This patch starts this procedure from within gsm48_gmm_authorize when
the mm->auth_state has been set to SGSN_AUTH_AUTHENTICATE and a call
to gsm0408_gprs_authenticate has been issued directly or indirectly
by the call to sgsn_auth_request.

sgsn: Do authentication based on SRES values
Currently the SRES value in the Auth & Ciph Response is ignored.
This patch checks the SRES value in response against the value stored
in mm->auth_triplet.sres. If they don't match, an Auth & Ciph Reject
message is sent to the MS. If they match, the mm->is_authenticated
flag is set.
Note that the procedure will not be started yet.

sgsn: Change Auth&Ciph timer handling
Currently mmctx_timer_start is called from within
gsm48_tx_gmm_auth_ciph_req which differs from the way e.g. the
identification procedure is implemented. It also makes it more
difficult to restart the procedure after timeout, which is not
implemented yet. In addition, the timer is not properly stopped when
an AUTH & CIPH response is received.
This patch removes this timer start from gsm48_tx_gmm_auth_ciph_req,
adds the retransmission of Auth & Ciph requests to the timer callback
function, and properly stops the timer in
gsm48_rx_gmm_auth_ciph_resp.

sgsn: Fix and enable auth/ciph message generation
Currently gsm48_tx_gmm_auth_ciph_req/_rej are commented out. In
addition, gsm48_tx_gmm_auth_ciph_req uses a wrong encoding (two byte TV instead of two nibbles TV) of the CKSN information element.
This patch fixes the encoding of the CKSN IE and enables the
functions mentioned above.

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
This function is called to delete an established MM context
silently without invoking a detach procedure.
It is called when a subscriber is cancelled by the HLR. This
generally happens, when an MS has moved to another routing area and
has to use another SGSN.

sgsn: Integrate subscriber handling into the SGSN
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. After the
IMSI/IMEI have been acquired, a request would be sent to the remote
peer. The attach/auth-ciph procedure continues when authorization
info has been received from the peer. This means, that
gprs_subscr_update() must be called then to tell the GMM layer
that it can proceed. A later commit will add VTY commands to do this
manually.

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.

msc: Add per subscriber keep_in_ram flag
Currently the keep_subscr flag in gsm_subscriber_group refers to a
whole group of subscribers which makes it difficult to really delete
single entries if the flag is set.
This patch adds a keep_in_ram field to gsm_subscriber which allows for
keeping subscriber objects in RAM while deleting others.
Note that really deleting an entry requires that both flags
(subscr_group->keep_subscr and subscr->keep_in_ram) are set to 0. So
only the latter should be used if a specification requires the
deletion of a subscriber entry.

msc: Add net parameter to trans_alloc
The trans_alloc function still uses the subscr object to access the
network object.
This patch adds an explicit net parameter to this function and
removes the access to subscr to obtain it.
