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 (363a67f814b5864ec6e28fda525a59da129792ea) \ N -- N -- N (5b4c44f4f0f902fa3762793b9a10b3392031f140) 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=5b4c44f4f0f902fa3762793b9a10b339… commit 5b4c44f4f0f902fa3762793b9a10b3392031f140 Author: Jacob Erlbeck &lt;jerlbeck(a)sysmocom.de&gt; Date: Thu Dec 18 15:00:29 2014 +0100 sgsn: GSUP client reconnect (WIP) TODO: - basically works - commit text - when requests are lost, the SGSN is (sometimes?) in a state, where when it receives repeated Attach Req message, it sends Update Location via GSUP, receives the Res but doesn't continue with the procedure.

This patch replaces that flag by a global cfg.require_authentication flag that enables/disables the use of the Auth & Ciph procedure for every subscriber. The flag is set by the VTY, if and only if the authorization policy is 'remote'. The VTY command - update-subscriber imsi IMSI insert authenticate <0-1> is removed.

In addition they are named like libosmocore's TLV parser functions and do not have a proper name prefix. Since it is planned to use them for other protocols, they need to be globally accessible. This patch moves them to gprs_utils.c and renames them. The new names are: lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed In the long term, these functions should be moved to libosmocore (and renamed again).
