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 (0cdb711b5716f0149a92e054e446f271e21d061a) \ N -- N -- N (99f2477653c1a1bff85cf0d5f823c4845fb46dc3) 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=99f2477653c1a1bff85cf0d5f823c484… commit 99f2477653c1a1bff85cf0d5f823c4845fb46dc3 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 19:50:37 2016 +0200 cosmetic: IuCS logging http://cgit.osmocom.org/openbsc/commit/?id=a9791df3b90e7458d0356a486df795a1… commit a9791df3b90e7458d0356a486df795a1226b046a Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 19:49:58 2016 +0200 add enum iu_event_type to string conversion http://cgit.osmocom.org/openbsc/commit/?id=d9202b342c996c56a7e10dbc744e50d5… commit d9202b342c996c56a7e10dbc744e50d56a933b2c Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 16:19:29 2016 +0200 comments and debug log for paging response http://cgit.osmocom.org/openbsc/commit/?id=c902bd40327643c161aefbd71bbf8c55… commit c902bd40327643c161aefbd71bbf8c5583051f17 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:59:10 2016 +0200 msc_paging_request(): remove unused parameters The network is known from subscr; the type is not applicable after MSCSPLIT; cbfn and data are obsoleted by explicit subscr_rx_paging_response(). http://cgit.osmocom.org/openbsc/commit/?id=ad21c3b8e384f9dcfd6ee8becb15fe2f… commit ad21c3b8e384f9dcfd6ee8becb15fe2f9d1869ba Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:58:43 2016 +0200 msc_paging_request(): make static it is never called outside of gsm_subscriber.c http://cgit.osmocom.org/openbsc/commit/?id=28fdbdcd539004958c8ae4077ed28307… commit 28fdbdcd539004958c8ae4077ed28307edf9c747 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Wed Apr 27 02:08:07 2016 +0200 msc: paging: use gsm_subscriber API to add Integrity Protection for IuCS During peliminary paging response testing, I introduced some code duplication. Remove that and instead call the code that was there before 63b99ced83773d923 ("add preliminary paging response handling, incomplete"). By calling the gsm_subscriber API, the connection is also secured and hence Integrity Protection is enabled for IuCS. http://cgit.osmocom.org/openbsc/commit/?id=903ad2e135f5d6358042e60ab0f1288f… commit 903ad2e135f5d6358042e60ab0f1288ff2e1f393 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 16:40:42 2016 +0200 cosmetic: msc: handle_paging_resp() tweaks Tweak debug logging, use paging category DPAG.

The probability that a subscriber would be able to take unauthorized action is slim, nevertheless checking authorization status with the database should happen before we accept a connection. http://cgit.osmocom.org/openbsc/commit/?id=3a9c52a5dc8a625b916193b7bea90254… commit 3a9c52a5dc8a625b916193b7bea90254af0e04f1 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:55:22 2016 +0200 paging: change subscr_paging_cb() into subscr_rx_paging_response() Remove one layer of callback indirection in paging. When a paging response arrives, we always want to first secure the connection, thus a fixed subscr_rx_paging_response() function is more appropriate and avoids having to store a cbfn. The actual actions to be taken upon successful paging are of course still in callback functions stored with each subscriber. http://cgit.osmocom.org/openbsc/commit/?id=c6580c5b2c11ca6bbc22676866c5cfe4… commit c6580c5b2c11ca6bbc22676866c5cfe4dc36596f Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:35:07 2016 +0200 Allow paging even though is_paging is false It doesn't really hurt to see whether we have paging responses queued for a given subscriber. Possibly a subscriber replied with a paging response later than we assumed the paging to be valid. http://cgit.osmocom.org/openbsc/commit/?id=fb845bb1df34170f841b330ee858016b… commit fb845bb1df34170f841b330ee858016bf6a09f5f Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:33:18 2016 +0200 cosmetic: subscr_paging_dispatch() comments/indent http://cgit.osmocom.org/openbsc/commit/?id=6f4e83beb05b7e4fd615504a7bf6a71a… commit 6f4e83beb05b7e4fd615504a7bf6a71afe15064d Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:32:32 2016 +0200 subscr_paging_dispatch(): use conn->subscr instead of separate param http://cgit.osmocom.org/openbsc/commit/?id=214302b306d6806605e1bec123dc9793… commit 214302b306d6806605e1bec123dc97934f9f6504 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:31:05 2016 +0200 cosmetic: subscr_paging_dispatch() comments/indent http://cgit.osmocom.org/openbsc/commit/?id=defe78f1e17cf34da0e602ad1a07c021… commit defe78f1e17cf34da0e602ad1a07c0214a7a81c9 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:27:26 2016 +0200 add comments on MSCSPLIT and paging http://cgit.osmocom.org/openbsc/commit/?id=061787878ceac939ed6b6882f4d810b5… commit 061787878ceac939ed6b6882f4d810b53774d24b Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:10:36 2016 +0200 gsm_04_08 mscsplit: subscr_request_channel() -> subscr_request_conn() Rename subscr_request_channel() to _conn() and remove the channel_type arg. The "channel" is a term from closely tied MSC+BSC code, after separation we shall call it a "connection", i.e. over IuCS or A. The channel_type arg is already unused from a previous MSCSPLIT commit. http://cgit.osmocom.org/openbsc/commit/?id=00007897d42232db0c29ebe543b24833… commit 00007897d42232db0c29ebe543b2483311e56785 Author: Neels Hofmeyr <nhofmeyr(a)sysmocom.de> Date: Mon May 2 15:02:32 2016 +0200 gsm_04_08: factor out subscr authorization check Add function subscr_authorized(), absorbing the guts of static authorize_subscriber() from gsm_04_08.c, except the parts specific to Location Updating. subscr_authorized() is a check that is to be added to validation of a paging response. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gsm_04_08.h | 2 + openbsc/include/openbsc/gsm_subscriber.h | 2 + openbsc/include/openbsc/iu.h | 6 ++ openbsc/src/libbsc/gsm_04_08_utils.c | 1 + openbsc/src/libbsc/paging.c | 6 ++ openbsc/src/libiu/iu.c | 11 +++- openbsc/src/libmsc/gsm_04_08.c | 94 ++------------------------------ openbsc/src/libmsc/gsm_subscriber.c | 29 ++++++++-- openbsc/src/libmsc/iu_cs.c | 2 + openbsc/src/libmsc/silent_call.c | 5 +- openbsc/src/osmo-cscn/cscn_main.c | 3 +- openbsc/src/osmo-cscn/iucs_ranap.c | 2 +- 12 files changed, 65 insertions(+), 98 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
