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 (320360e2a5f79585c86b5b4260c8266b3ee18d31)
\
N -- N -- N (798f3c247984a53ab8e5c68beff106b45a40b7ae)
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: Don't assign a new P-TMSI if one is pending (TODO)
Currently every time a RA Update Req or an Attach Req is processed, a
new P-TMSI is alocated. When an MS issues another of these messages
before it has completed the first procedure, old_ptmsi is replaced by
ptmsi (and thus lost) and ptmsi is replaced by the newly allocated
P-TMSI. This can confuse the gbproxy, which can loose track of the
logical link then. At least a blackberry emits a double set of RA Upd
Req messages from time to time which may be just 20ms apart.
This patch adds a check whether mm->ptmsi or mm->old_ptmsi are not
both set. If both are set, the P-TMSI is not re-allocated. This is
only the case, if the Complete message has not been received since
that resets old_ptmsi.

sgsn: Cleanup after RA Update Reject (TODO)
Currently, the LLME is not cleanup up after sending an RA Update
Reject. This happens after entering a routing area from outside,
since in that case the SGSN sends an RA Update Reject (implicitly
detached) which causes the MS to restart the attach procedure.
This patch changes gsm48_rx_gmm_ra_upd_req to unassign the LLME or
free the MM context (if available) after a Reject message has been
sent.

sgsn: Add 'acl-only' authentication policy
Currently the VTY 'auth-policy' command results in setting or clearing
the acl_enabled flag. This also enables the matching of the MCC/MNC
prefix of the IMSI.
This patch adds an additional policy 'acl-only' which disables the
MCC/MNC matching and relies on the ACL only.

sgsn: Make authorization asynchronous
Currently the authorization of an IMSI is done by checking ACLs
synchronously which is not feasible when the subscriber data has to
be retrieved from an external source.
This patch changes this by using a callback when the information is
available. This is also done when only ACL are checked, in this case
the callback is invoked from within sgsn_auth_request(). The callback
function sgsn_update_subscriber_data calls sgsn_auth_update which
in turn calls either gsm0408_gprs_access_granted or
gsm0408_gprs_access_denied. gsm48_gmm_authorize is extended by a call
to sgsn_auth_request when IMSI and IMEI are available but the
auth_state is unknown.
The change has been successfully tested with single phones (E71 and
IPhone 5c).

bsc: Fix use-after-free on OML NM messages from the BTS
Currently the sign_link pointer is dereferenced after a call to
osmo_signal_dispatch, which can indirectly call
e1inp_sign_link_destroy. If that happens, accessing *sign_link is
illegal and can lead to a segmentation violation.
Since only the bts pointer is needed from sign_link after the call to
osmo_signal_dispatch, this patch changes abis_nm_rcvmsg_fom to save
that pointer to a local variable earlier.

sgsn: Move IMSI authorization to gsm48_gmm_authorize
Currently the IMSI is only checked immediately when an Attach Request
is received that contains an IMSI IE. If it contains a P-TMSI
instead, access is always granted.
This commit moves the IMSI check to gsm48_gmm_authorize where it is
applied when IMSI and IMEI have been acquired. This fixes the
authorization when the Attach Accept doesn't contain an IMSI.

sgsn: Fix LLME leak when forcing a reattach
Currently when forceing a reattach by sending a Detach
Request (reattach), the SGSN waits for the Detach Accept until it
frees the MM context (if present) and the LLME. If that message gets
lost or isn't sent by the MS, the LLME is never freed if it isn't
bound to an MM context.
This patch adds code to free the MM context/LLME when forcing a
reattachment.

sgsn: Split gsm0408_gprs_force_reattach into 2 functions
This patch replaces gsm0408_gprs_force_reattach(msg, mmctx) by two
functions
- gsm0408_gprs_force_reattach(mmctx)
- gsm0408_gprs_force_reattach_oldmsg(msg)
The old function basically consists of the code of the two new
functions, where the code patch selected depends on mmctx == NULL,
which is harder to maintain, less obvious to use, and not consistent
with many other SGSN functions.

cleaned up if the MS reattaches.
This patch replaces all of these assignments by a call to
mm_ctx_cleanup_free.

sgsn: Cleanup GMM state transitions
Currently the GMM state is set to GMM-REGISTERED when an Attach
Accept or a RA Update Accept message is sent, even if a new P-TMSI is
included. In this case 04.08 requires (see 4.7.3.1.3 and 4.7.5.1.3),
that the state is set to GMM-COMMON-PROCEDURE-INITIATED when the
Accept is sent. When the Complete is received, the SGSN shall set
the state to GMM-REGISTERED.
This patch modifies the state updates accordingly.

sgsn: Reorganize and fix gsm48_gmm_authorize
Currently the order of the 'if' clauses in gsm48_gmm_authorize
doesn't match the order in which the conditional parts are entered.
This makes it difficult to maintain. In addition the t3350_mode is
not stored in every path, so that this information is lost when the
identification procedure is started. Since the default value
coincidentally is GMM_T3350_MODE_ATT, this doesn't hurt for Attach
Requests which are the only messages that initially trigger the
authentication yet.
This patch changes the order of the 'if' clause to match the
processing order, it removes the t3350_mode parameter entirely and
introduces a mm->pending_req field. The latter must be set when the
request that causes the authorization before calling
gsm48_gmm_authorize. The gprs_t3350_mode enum is extended by
GMM_T3350_MODE_NONE (value 0, which is the default) to make it
possible to detect related initialisation errors or race conditions.

gbproxy: Reset TLLIs when the link_info is found by IMSI/P-TMSI
Currently when the MS does a re-attach without doing a proper detach
first, the gbproxy uses the old local TLLI if patching and the keep

TLLI patching is also enabled.
This patch changes gbproxy_get_link_info_ul to reset all TLLIs within the
link_info if the message contains an unknown TLLI and an MI. This is
generally the case with Attach Request messages.
