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 (e0eb96d6a712a0278ecd00b7a1a9ba9685c306bf) \ N -- N -- N (47c7031e8374c7f62fee4302ea4542db337dd805) 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. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=47c7031e8374c7f62fee4302ea4542db… commit 47c7031e8374c7f62fee4302ea4542db337dd805 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Sep 30 13:53:26 2014 +0200 sgsn: Added TODOs (TODO) 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 - implement age based MM context expiry - remove this commit Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=a6f76044db12fad60f40df8711d54059… commit a6f76044db12fad60f40df8711d5405956c9d121 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Oct 17 10:08:02 2014 +0200 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.

Therefore there is no lower limit of the distance between 2 identical P-TMSI. This patch changes the implementation to discard any random value above 2^30 and to generate a new random number in that case until a fitting number is found (or a repetition limit is reached). This way, all number below 2^30 within the PRNG's period are used.

This patch adds the missing message and put the whole request handling of this procedure into a separate function.

This behaviour is not compliant to GSM 09.02, 20.3.3.2 (Subscriber data management/SGSN) where it is defined, that an error ("Unidentified subscriber") shall be returned. This patch removes the case distinction, so that an existing subscriber entry is required for all incoming GSUP messages.

This patch adds GSUP error replies for these requests (and only for requests). It also adds tests for these cases. Note that several of these tests check for GMM_CAUSE_MSGT_NOTEXIST_NOTIMPL, which will have to be changed, when the features are implemented.

This patch implements this by adding corresponding state and checks to gprs_subscr_purge, gprs_subscr_location_update, and gprs_subscr_update_auth_info. If an Update Location or a Send Auth Info Req procedure is not started because of blocking, the retry mechanism is aborted to shorten the blocking time. The outstanding Purge MS procedure itself is not aborted.
