This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)".

The branch, jerlbeck/wip/gprs-patching has been updated discards d4e5342b0f3b28caaf10bc51e916904572074e25 (commit) discards c6abb6e5708fb85bdcba0e02b06f4d4bdc246fbe (commit) discards 279b012bd62518c45a4fa300a94cd9bfe5219665 (commit) via 320360e2a5f79585c86b5b4260c8266b3ee18d31 (commit) via bfe6df93178cc46c317edb4aa53cd5643a30896b (commit) via 2d193dc608e8cd15482ca477f04fa24762136707 (commit) via a1f9bd765cda631ddcd7c0f6700b6ad013f5c31a (commit) via 3edce24bbad14d2c205678df1373e23d639eaf65 (commit) via d63d2bbe52d4cd789559cd18fa4d01548b8a6e3f (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 (d4e5342b0f3b28caaf10bc51e916904572074e25) \ N -- N -- N (320360e2a5f79585c86b5b4260c8266b3ee18d31)

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

sgsn: Notify an affected MM context if an ACL rule is removed

Currently if an ACL access rule is removed, MS already attached are not affected until they try to reattach to the SGSN.

This patch extends sgsn_acl_del to re-authenticate an MM context if it matches the IMSI.

sgsn: Add 'acl-only' authentication policy

Currently the VTY 'auth-policy' command results in setting or clearing the acl_enabled flag. 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.

sgsn/test: Add VTY tests for the SGSN

sgsn: Make authorization asynchronous

Currently the authorization of an IMSI is done by checking ACLs synchronously which is not feasible when the subscriber data has to be retrieved from an external source.

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).
