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 (13713264aa539ce1343ad6c7dd0f8308b242a892)
\
N -- N -- N (a43e25b50c1ad30a597e336c8f47e274a9911186)
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: 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.
TODO:
- find the real source for the problem
- add test cases derived from what is being described in the ticket
Ticket: OW#1322

gprs: Pass GMM causes related to the MSC connection
Currently the error causes MSC_TEMP_NOTREACH, NET_FAIL, and
CONGESTION are silently dropped to force the MS to continue. On the
other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5,
require the MS to retry the attachment procedure for cause codes
above 15 instead of disabling GPRS. All of the mentioned GMM causes
have codes above 15, so using a REJECT message including the cause
code is a better choice. This way, the retry algorithm based on T3311
(15s, 5 times) and T3302 (default 12min) could be used.
This patch modifies gprs_subscr_handle_gsup_auth_err and
gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access
has beed denied, except that the corresponding subscriber's
information fields are not cleared.
This has been successfully tested which an iphone which enters a
retry loop as it is being described in the specification.

gprs: Use LOGMMCTX for logging in gprs_susbcriber.c
To unify the layout of the logging messages, this patch replaces some
calls to LOGP by calls to LOGMMCTXP.

gprs: Let GSUP parser functions return GMM causes on errors
Currently the GSUP message handling function in gprs_subscriber.c and
the functions in gprs_gsup_messages.c are not consistent with respect
to the return codes if an error happens. Albeit all error return
codes are negative, the semantics of the absolute value are not
clearly defined. In addition, some return codes are not passed to the
calling function.
This path changes these functions to always return a negated GMM
cause value in case of errors. Return values of called parser
functions are not longer ignored.

gprs: Use the cause value in GSUP error messages
Currently always a cause with the meaning of 'access denied' is
assumed. gprs_subscr_handle_gsup_auth_err just clears the auth
triplets and the authorized flag before calling the update function.
gprs_subscr_handle_gsup_upd_loc_err only clears the authorized flag
and calls the update function. This means, that an MS will not retry
to attach even on temporary network errors.
This patch changes these functions to use the GSUP error cause value
to decide, whether to clear the corresponding subscriber fields, to
just continue with the corresponding update function, or to log,
ignore and not pass the cause to the MS in case the error is directly
related to the GSUP protocol. The subscriber's error_cause field is
updated, if the update function is going to be called. The
error_cause fielt is reset on non-error GSUP messages.
