For the statistics we do need to have an allocated config,
otherwise we will nicely crash.

|
We will reset the multiplex in a DLCX message and then
we can reset the multiplex as well...even if the MGCP
connection is staying open. or at least this is a theory.
The MSC likes to leave a connection open during CallControl
when hanging up early enough in the process.

This allows that we can print the Nr. next to the lac
and it allows us to change the lac at runtime without
reconnecting the BSC.

Remove the code to parse port as we need to discover the
BTS behind the nat and most likely it will have a different
port than the one advertised by the BTS.
This reverts commit c6a1fe773d16eb20d4cb1d3097761419436f4537.
|
|
No change needed to the code.
|
|
Fix the test to search for the original message instead
of the already patched one that should not find any items
anyway.
The remove is called on already patched connections so we
need to match it with the patch reference count.
|
|
Extract the port from the BSS's MGCP Gateway so we know
where to forward the data to.
|
|
The MGCP protocol parsing is adding '\0' to make sure we do not
parse beyond where we should parse. This does not mix with strtok
or similiar routines.
For now we will read the msg into a global array first, then copy
it to the msgb for mgcp protocol handling and if we are required
to forward it to the MGCP we have a untouched copy we will modify
into our own msgb.

Attempt to find the message by transaction id, then patch
the response and use the IP/PORT of the local network, update
the ci with the one from the BSC.
This is currently not tracking any state of the MGCP and will
not handle two bsc's... this will need to happen later.
With this in we should be feature complete and now enter the
mode of making all of this work reliable and fixing thinko's
and other bugs.

Add code to change the ip and port for audio data inside
MGCP messages. This is needed because the BSS might be
behind the NAT and can not reach the network directly and
might be behind a nat so the announced sourceport is not
the one as we see it.

This information will be needed when we are trying to forward
MGCP connections to and from the BSC through the IPA protocol.

* Return the SCCP connection. This will be needed to store the
assigned timeslot in there.
* Update code to work with this change
* This uncovered a bug in the CC handling, at the time the BSC was
passed it was still a null pointer and the code would have failed.

This test case tests connectiont tracking by sending
a CR, getting a CC, sending a DTAP, receiving a DTAP,
receiving a RLSD, sending a RLC. It verifies that the
messages are properly patched specially the references
at the BSC.

Do not run into the situation where we need to filter in one
direction but it should not be filtered..
|
|
Introduce a bsc_nat_parse method to parse a IP Access method
into various parts. Write out the IPA Proto, in case SCCP is used,
store the msg type, pointers to the source/dest local reference and
other information.
Use the result of bsc_nat_parse inside the bsc_nat_filter method
to decide if the message should be dropped or not.
In the future the bsc_nat_parse result will be used for patching
SCCP references and other parts of the message.
The filter language should be able to filter the msg type of SCCP
messages and gain the "NOT" word in the filter language.
