Harald Welte 51c4b5c279 map_masq: Fix patching of IMSI and SC-Addr in SRI-RES and MO-FW-SM 2013-04-24 12:44:17 +05:30
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.

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 fce6cf18dd IMSI rewrite: change from prefix rewrite to full N:M rewriting 2012-02-20 07:56:16 +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 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.

Harald Welte d1410ae677 MAP MASQ: Ensure process can respawn without errors 
We re-generate the SCCP GT translation table at respawn, and in that
case the tuples already include the list-converted global titles,
which used to cause a function_clause error.

Harald Welte 6009f6e5fe MAP MASQ: Fix config file reload 
As config file reload may be triggered from a process elsewhere, we need
to explicitly specify the Application name 'mgw_nat' to access the
application environment.

Harald Welte e78474eeb9 MAP MASQ: Translate the source G-MSC address in SRI request 
We translate the same way as we did the SCCP CallingPartyAddr
in sccp_masq, by utilizing the sccp_masq:lookup_masq_addr() function.
