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 (70c53a622635f1770b2eef375c260ac731d40780) \ N -- N -- N (0e1f5ad735ca326c34fd7758e1f1304341eacde7) 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=0e1f5ad735ca326c34fd7758e1f130434... commit 0e1f5ad735ca326c34fd7758e1f1304341eacde7 Author: Jacob Erlbeck <jerlbeck@sysmocom.de> Date: Fri Nov 28 14:55:25 2014 +0100 sgsn: Work on 2 phase authorization (WIP) This implements the MAP way of subscriber validation when the MS tries an Attach Request: 1. perform authentication (optionally invoke the sendAuthInfo procedure), starts the AuthAndCiph procedure 2. perform update location 3. insert subscriber data 4. finish the update location 5.

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.

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.

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.

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.

This patch adds sgsn_auth_update_all() that iterates through allMM contexts and calls sgsn_auth_update() on each of them.

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.

This adds a dependency on gsm_network even if only the function defined in gsm_subscriber_base.c are used. This patch adds a new struct gsm_subscriber_group which contains the keep_subscr flag and a back reference to the network object. The latter is not dereferenced in gsm_subscriber_base.c, so it can safely be set to NULL when only that part of the gsm_subscriber API is being used. It also changes that API to use gsm_subscriber_group instead of gsm_network parameters. Since there are some places where a pointer to the gsm_network is needed but where only a gsm_subscriber is available, a 'net' back pointer is added to the group struct, too. Nevertheless subscr group and network could be separated completely, but this is not the topic of this commit.
