Harald Welte 455b4785b9 fix isup_party_nat00_internationalize() for empty number 
Avoid running into an exception in case the calling party is an empty
number "[]" (I guess call screening is applied).

Harald Welte e8b2173386 map_masq: Only one matching function for MO-ForwardSM-Arg 
We have both the smsCDA and the imsi_list translation in the
MO-ForwardSM-Arg, and have to put both in one matching function, as in
the case of multiple matching functions only one of them will be
executed.

Harald Welte 04bc9f8645 map_masq: Fix processing of MO-ForwardSM-Arg 2013-02-06 09:37:00 +01:00
Harald Welte 6675c74d37 map_masq: don't assume that imsi_list is a gb_tree anymore 
Introduce a imsi_list:num_entries/1 function to determine number of
entries.
 2013-02-06 09:14:37 +01:00
Harald Welte 7bd1d4ae4f map_masq/imsi_list: bi-directional mapping, also change MO-ForwardSM-Arg 
This introduces a second gb_tree of imsi mappings for the inverse
direction, in order to mangle MO-ForwardSM-Arg

Harald Welte 0be74df53e mgw_nat: Update to new xua_codec based m2ua parser 2013-01-26 16:41:59 +01:00
Harald Welte 8a7e6597c4 add mangle_tt_sri_sm to list of modules in mgw_nat application 2012-05-30 12:11:34 +02:00
Harald Welte cb190c278d add new mangle_tt_sri_sm module and associated eunit tests 
This module is able to match a SCCP message against a given
Destination-GT prefix and checks if the message contains an
Invoke(SRI-for-SM).  If both conditions are true, it alters the TT from
whatever it may currently be to 3.

This is used for SMS special routing cases at the STP.

Harald Welte fb222d9112 consistently license all files under AGPLv3 2012-04-16 13:19:15 +02:00
Harald Welte 0b452a8eb9 Add Erlang Public License compatibility notice 2012-04-16 13:18:04 +02:00
Harald Welte 3b10578cc3 sccp_masq: Fix config_reload / use named_tables 
we cannot store persistent/dynamically created state like the references
to our SCCP MASQ state tables in the application environment, as the
environment gets cleared and re-initialized by the
application_controller on osmo_util:reload_config().

So now we use named_tables instead to ensure persistency accross
config reload

Harald Welte fce6cf18dd IMSI rewrite: change from prefix rewrite to full N:M rewriting 2012-02-20 07:56:16 +01:00
Harald Welte 80743f8bab mgw_nat: As of 2012-02-14, MSC -> STP direction uses international format 
We used to convert from inetrnational format into national format on the
MSC->STP direction of ISUP messages.  This is no longer the case, we now
need to send exclusively international format.

Harald Welte 432ea566ff mgw_nat: add some more comments to the code 2012-02-14 09:49:51 +01:00
Harald Welte a53a63a8da mgw_nat: explicitly state application name in get/set_env() 
This makes sure that even if some function is called from a different
context, it still will use the correct configuration data.

Harald Welte 71d8833bbe vfuk test: fix 'terminate()' cleanup in eunit test 2012-02-13 20:55:15 +01:00
Harald Welte 9fe07294ff mgw_nat: add IMSI matching / prefix-rewrite for SRI-SM 
When the MSC responds with a SRI-SM-Response, we match against a
user-supplied list of IMSs.  If there is a match, we replace the
known prefix of the IMSI with a new known prefix.
 2012-02-13 20:54:17 +01:00
Harald Welte e6d3ea273d vfuk_onw_tests: use record syntax to be more robust 
We shouldn't make detailed assumptions about the tuple structure of the
underlying auto-geenrated records for the MAP protocol spec...

Harald Welte 594c2568d9 sctp_handler: Terminate process in case SCTP peer becomes unreachable 
This occurred in case of an IP network outage or MSC outage.  We need to
properly restart the mgw_nat_usr process in order to recover.
 2011-09-24 14:33:00 +02:00
Harald Welte 61d9a9eae0 sccp_masq: mark ets tables as "public" 
This is neccessary, as the code will execute in the context of various
mgw_nat_usr processes (one for each signalling link).
 2011-09-24 14:27:31 +02:00
Harald Welte 392ce05473 make sure sccp_masq is using the application environment for ets 2011-09-24 12:07:44 +02:00
Harald Welte 26647e0f4f make sure LoopDat really is only the loop date and not {ok, LoopDat} 2011-09-24 12:07:25 +02:00
Harald Welte ce995d3d30 mgw_nat: Add ability to translate multiple signalling links 
The mgw_nat_sup supervisor now starts one mgw_nat_usr process for each
MSC-STP link defined in the configuration file.  However, the actual
translation/mangling/masquerading configuration as well as runtime state
like allocated SCCP mappings is global/shared between all signalling
links.

Furthermore, a new mgw_nat_adm process is introduced to ensure config
file reloading (formerly handled by the single mgw_nat_usr) does not
have to run in the supervisor (and risk crashing it).

Harald Welte f83e20e307 map_masq: Fix copy+paste mistake causing 'end' structures in 'continue' 2011-05-23 12:41:14 +02:00
Harald Welte 71b158fca6 mgw_nat: Fix bug where we skipped the SCCP static mangling before masq 2011-05-23 12:39:36 +02:00
Harald Welte 097ad255f6 MGW_NAT: disable nagle on SCTP sockets 
This should cut down our latencies in forwarding the messages in
the mgw_nat.  Thanks to zecke for the hint...

Harald Welte 3607d36bd8 propagate reload_config() from app to usr to action handler 2011-04-14 17:46:53 +02:00
Harald Welte 99e92c2426 VFUK actor: Use new GTT matching code 
This allows us to use the osmo_ss7_gtt module for matching Sccp
addresses including GT ranges.

The eunit tests have been extended to test the new code.
 2011-04-06 17:22:30 +02:00
Harald Welte a227e76dff MGW NAT: Store a reference to the actor module, not the rewrite_actor/5 function 
By keeping a module reference, we can call multiple functions inside the
module, and not just one.  This will allow us to propagate a 'reload_config'
function call into the rewrite actors.

Harald Welte eea20e1e82 Use lists:keysearch() instead of lists:keyfind() for R12A compat

Harald Welte eee3eac368 [PATCH] ONW_VFUK / Camel Phase mangling: Add pcap-based testing 
And use the routines from osmo_ss7_pcap instead of our own local
copy.
