The branch, master has been updated via de4bbc714600b9db0b913705efc3064defacae18 (commit) via aec03a1f136abcd9bf59f4ec7cce9bd490fe8c81 (commit) via 59ac49dc1fd3b1435ef2eeb0b5daf555a946cde6 (commit) from 175a240285897317fff4a94e4f9b62408797b4b6 (commit) 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=de4bbc714600b9db0b913705efc3064d… commit de4bbc714600b9db0b913705efc3064defacae18 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Nov 24 15:04:15 2014 +0100 sgsn/test: Add test case for unexpected Detach Accepts The commit "sgsn: Don't send XID reset after Detach Accept" fixed the SGSN to not respond to a Detach Accept message when there is no MM context. This patch adds a test case to verify, that there is really no message sent in that case. The test fails when the commit mentioned aboved is reverted.

This adds a dependency on the implementation of rand() and thus the libc used. This breaks the test e.g. on FreeBSD. This patch modifies test_gmm_attach() to srand(1) first, generate the P-TMSI, and finally srand(1) again before starting the test.

This leads to a failing attachment procedure when TLLI patching is also enabled. This patch changes gbproxy_update_link_state_ul to reset all TLLIs within the link_info if the message contains an unknown TLLI and an MI. This is generally the case with Attach Request messages. The gbproxy_get_link_info_ul gets an additional tlli_is_valid output parameter that is set, when a TLLI was present and found. This flag is then used instead of checking tlli.current == 0 to set TLLI/P-TMSI e.g. Attach Requests when a link_info was already present for the P-TMSI/IMSI used in such a request.
