The branch, ciaby/rhizomatica-token has been updated discards b52338d4a9ef6442b2e23228f24cb62e49f8d978 (commit) via b33b50fdbc44f1d22584383df1018b28e80f50d8 (commit) via cc4f017034bce80516c09bf2347a094d36954500 (commit) 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 (b52338d4a9ef6442b2e23228f24cb62e49f8d978) \ N -- N -- N (b33b50fdbc44f1d22584383df1018b28e80f50d8) 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=b33b50fdbc44f1d22584383df1018b28… commit b33b50fdbc44f1d22584383df1018b28e80f50d8 Author: Ciaby <ciaby(a)rhizomatica.org> Date: Sun Nov 16 23:07:55 2014 -0600 Updated changelog, bumped version to +rhizo3. http://cgit.osmocom.org/openbsc/commit/?id=cc4f017034bce80516c09bf2347a094d… commit cc4f017034bce80516c09bf2347a094d36954500 Author: Ciaby <ciaby(a)rhizomatica.org> Date: Sun Nov 16 23:06:47 2014 -0600 Handover fix, needs to be tested. ----------------------------------------------------------------------- Summary of changes: debian/changelog | 3 ++- openbsc/src/libbsc/handover_logic.c | 4 ++++ 2 files changed, 6 insertions(+), 1 deletion(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

What is different is that the tag and length do not stop at byte boundaries. This commit introduces methods to msgb and tlv to be able to create such a tag/length header and a way to parse it using the tlv_parse routine. When it comes to parsing we have an issue that the new TLV_TYPE_T7L9V should not be mixed with the other types inside the same tlv definition. This is due the bitshifting required to identify the tag. The code likely requires work on big-endian machines but so does most of the other code as well. ----------------------------------------------------------------------- Summary of changes: .gitignore | 1 + include/osmocom/gsm/tlv.h | 14 ++++ src/gsm/tlv_parser.c | 19 +++++ tests/Makefile.am | 8 +- tests/testsuite.at | 6 ++ tests/tlv/tlv_test.c | 205 ++++++++++++++++++++++++++++++++++++++++++++++ tests/tlv/tlv_test.ok | 8 ++ 7 files changed, 259 insertions(+), 2 deletions(-) create mode 100644 tests/tlv/tlv_test.c create mode 100644 tests/tlv/tlv_test.ok hooks/post-receive -- An utility library for Open Source Mobile Communications

The MSC already uses a similar struct named gsm_subscriber whose implementation is split into a generic part (allocation, retrieval, reference counting, list maintenance) and MSC related parts. For GPRS, only the generic part will be used and specific fields may be added when needed. This patch adds a field mm to struct gsm_subscriber that will be used by the SGSN to store a reference to the current MM context (or NULL if there is none). This also adds a field subscr to struct sgsn_mm_ctx that reversely points to a gsm_subscriber (or NULL if there is none). Either both fields are NULL or both fields are non-NULL. Note that subscr is being reference counted.

Since then global sgsn variable is already being used in that file and since other parts of the SGSN related code also rely on a global sgsn singleton, these parameters pretend to provide a flexibility that is not really supported. Therefore this patch removes these parameters except for the ACL related functions, which do not call code that uses the sgsn variable.

This doesn't match the way remote authorization would work, so that there is a second call to sgsn_auth_state already present in sgsn_auth_update. This patch removes the autorization check completely from sgsn_auth_request which in turn calls sgsn_auth_update directly now.

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 set. If both are set, the P-TMSI is not re-allocated. This is only the case, when the Complete message has not been received yet, since that message will reset old_ptmsi.

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. The LLME is also not updated if an Attach Request with message errors (encoding, invalid MI type) is received or if an MM context cannot be allocated. This patch changes gsm48_rx_gmm_ra_upd_req and gsm48_rx_gmm_att_req to unassign the LLME or free the MM context (if available) after a Reject message has been sent.

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.

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).

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.

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.

This can lead to left-over MM contexts which are only cleaned up if the MS reattaches. This patch replaces all of these assignments by a call to mm_ctx_cleanup_free.

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. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=93eae8ec78d145cf87b7858ebee60c72… commit 93eae8ec78d145cf87b7858ebee60c72da7a2d20 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Oct 28 12:23:29 2014 +0100 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.

The MSC already uses a similar struct named gsm_subscriber whose implementation is split into a generic part (allocation, retrieval, reference counting, list maintenance) and MSC related parts. For GPRS, only the generic part will be used and specific fields may be added when needed. This patch adds a field mm to struct gsm_subscriber that will be used by the SGSN to store a reference to the current MM context (or NULL if there is none). This also adds a field subscr to struct sgsn_mm_ctx that reversely points to a gsm_subscriber (or NULL if there is none). Either both fields are NULL or both fields are non-NULL. Note that subscr is being reference counted.
