commit 337343d159888886eaa68476b70dbe19db93845b Merge: 3815942 d26b8fc Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun May 3 22:34:01 2015 +0200

Merge branch 'zecke/features/acc-list'

Integrate the change and see how it is going. The unit tests for the NAT look good so we might not have regressions.

commit d26b8fcbe22eb4a56c87f0114a0e826551243511 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 22:45:32 2015 +0200

bsc: Send a LU Reject in case it has been filtered

In case we filter the request and it was a Location Updating Procedure we should reject it.

http://cgit.osmocom.org/openbsc/commit/?id=ec0cb7c64d5d42e8d0d599b209a3eabac...

commit ec0cb7c64d5d42e8d0d599b209a3eabacfceba60 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 20:53:42 2015 +0200

bsc: Add access list filtering to the BSC

http://cgit.osmocom.org/openbsc/commit/?id=d6332809d8313903c65ccd28646f41b7c...

commit d6332809d8313903c65ccd28646f41b7c1aa6b99 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 19:46:20 2015 +0200

bsc: Add access lists to the MSC and the BSC

It is a bit arbitary to decide which one is the global and which one is the local one. We might change it around. I don't think we want to introduce it based on BTS.

http://cgit.osmocom.org/openbsc/commit/?id=c652913674ecc30f8d234878a17baa623...

commit c652913674ecc30f8d234878a17baa623cbacf99 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 21:03:49 2015 +0200

filter: Move the con_type into the filter_state

http://cgit.osmocom.org/openbsc/commit/?id=06a88fa0ae1f86cef0a23a1462bfef950...

commit 06a88fa0ae1f86cef0a23a1462bfef950418ea36 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 19:34:12 2015 +0200

filter: Move from DNAT to DFILTER category

http://cgit.osmocom.org/openbsc/commit/?id=4e8176d0c9c9a98f32cb4541b4f986de0...

commit 4e8176d0c9c9a98f32cb4541b4f986de0011d4b9 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 19:20:09 2015 +0200

filter: Remove bsc_connection from the filter API

Remove the last occurence of NAT datastructures in the filtering module and add the ctx to the filter request structure.

http://cgit.osmocom.org/openbsc/commit/?id=c09f8a3b7fb94ccef41e33c32bfe2bff1...

commit c09f8a3b7fb94ccef41e33c32bfe2bff1ffe0e44 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 19:13:27 2015 +0200

filter: Remove nat_sccp_connection from public API

http://cgit.osmocom.org/openbsc/commit/?id=81dbfe412c8196df443f38bf4fbea4f98...

commit 81dbfe412c8196df443f38bf4fbea4f9897607ef Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 18:58:55 2015 +0200

filter: Remove the bsc_connection from the internal functions

http://cgit.osmocom.org/openbsc/commit/?id=71857d72426c75e4bb71c3843a9eeeff5...

commit 71857d72426c75e4bb71c3843a9eeeff53eca37d Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 18:48:27 2015 +0200

filter: Put all the parameters in a struct to avoid order issues

With the "local" and "global" list name we might pick the wrong argument. Avoid it by passing them as a struct.

http://cgit.osmocom.org/openbsc/commit/?id=a0478814bc1c56a9e5648ffecd7c11671...

commit a0478814bc1c56a9e5648ffecd7c11671804e6ff Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 18:42:45 2015 +0200

filter: Remove NAT knowledge from auth_imsi

Push back the parameters we need to pass. auth_imsi doesn't know anything about the nat now.

http://cgit.osmocom.org/openbsc/commit/?id=4ba947bf4b80b553a3411ec1fd29c4543...

commit 4ba947bf4b80b553a3411ec1fd29c45430bd6c40 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 18:07:45 2015 +0200

filter: Separate SCCP/BSSAP extraction and gsm48 code

For the BSC we will have the gsm48_hdr and don't need to find data within SCCP. For legacy reasons we need to initialize con_type, imsi, reject causes early on and need to do the same in the filter method.

commit c36a6d5705830a6fd6e41e684dc031db35165e04 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 16:55:28 2015 +0200

filter: More renaming and remove of "NAT" from it

http://cgit.osmocom.org/openbsc/commit/?id=14b2cd9f321974e211f3291a6ccc2d1aa...

commit 14b2cd9f321974e211f3291a6ccc2d1aaaf948d1 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sun Apr 5 16:50:34 2015 +0200

filter: Rename BSC to LOCAL and NAT to GLOBAL

http://cgit.osmocom.org/openbsc/commit/?id=a1e6bd6768e61828823da3ba774e55b6f...

commit a1e6bd6768e61828823da3ba774e55b6f89559fc Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 22:40:12 2015 +0200

filter: Remove nat from bsc_nat_acc_lst and replace with msg

http://cgit.osmocom.org/openbsc/commit/?id=d7e04b9956bb7d579697604fff6ba67fc...

commit d7e04b9956bb7d579697604fff6ba67fc6b9e52d Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 22:28:32 2015 +0200

filter: Cease out "struct bsc_nat" from the API

This means we need to require a talloc context and simply operate on the list. I had considered creating a structure to hold the list head but I didn't find any other members so omitted it for now.

http://cgit.osmocom.org/openbsc/commit/?id=d04d009f473d89a426c16dd24e5a4c692...

commit d04d009f473d89a426c16dd24e5a4c692caf0017 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 22:14:34 2015 +0200

filter: Move VTY code into the filter module

http://cgit.osmocom.org/openbsc/commit/?id=4579bb1ed7464d66343d84846314ec66e...

commit 4579bb1ed7464d66343d84846314ec66e6f8cccd Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 21:55:08 2015 +0200

filter: Move the access list management around

http://cgit.osmocom.org/openbsc/commit/?id=973dbaeebdbdbd8fed417cdfd16964409...

commit 973dbaeebdbdbd8fed417cdfd169644093389d05 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 20:47:03 2015 +0200

filter: Move the method definition to the filter module

Move the filter methods to the filter module. This is still only usable for the NAT and the _dt/_cr filter routines need to move back to the bsc_nat in the long run.

http://cgit.osmocom.org/openbsc/commit/?id=4247cead2b77b2ad8ae2a6c1b48a45030...

commit 4247cead2b77b2ad8ae2a6c1b48a450309185bb3 Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Sat Apr 4 18:42:46 2015 +0200

filter: Move the gsm 04.08 filter to a common place

For customer requirements we want to be able to do filtering on the BSC as well. The same messages need to be scanned and the same access-lists will be looked at. In the future we might even split traffic based on the IMSI. Begin with moving the code to a new top level directory and then renaming and removing the nat dependency.
