Harald Welte bdf3fd1dc4 don't include hnbgw.h from ranap header files 
To use libosmo-ranap from outside of this repository, we need to
eliminated all dependencies to local header files

Harald Welte c4338deee9 hnbgw: Bring all parts together 
We now have the RUA and SUA parts interconnected by the
context ID mapper, and should be able to pass messages back and forward
between both sides.

Unfortunately this touches a bit of everything, but the structures are
all still very much in flux.  Hopefully they will start to stabilize at
some point soon...

Harald Welte 90256bad58 Add a context mapper to map RUA ContextIDs <-> SUA Connection IDs 2015-12-23 22:13:53 +01:00
Harald Welte f42317ba9c Introduce DRANAP/DRUA log categories to separate logging 2015-12-23 15:37:17 +01:00
Harald Welte ffa7c0ad39 use msgb_sctp_ppid() from libosmo-netif, remove local declaration 2015-12-23 00:04:05 +01:00
Harald Welte 75a4e65f52 hnbgw: Add SUA client socket towards localhost 
This socket doesn't do much yet except to connect to localhost:14001

The host/port needs to be made configurable, and the RUA<->SUA
interfacing needs to be implemented.

Also, we'll need two SUA sockets, one for MSC and one for SGSN.

Daniel Willmann 269b8ac7ee hnbgw: Free msgb when connection is closed 2015-12-22 16:40:46 +01:00
Daniel Willmann 28b9ec1473 Enable vty command to output talloc report 
I don't think I can print this into a string and thus output it via VTY.
In that case it might be smarte to do in a signal handler

Daniel Willmann bded9841b5 hnbgw: Change logging priorities and add HNBAP category 
Log hnbap messages to the HNBAP category. Change MAIN category to only
log INFO and above and change SCTP notification message to debug.

Daniel Willmann 4267a29ee0 hnbgw: Handle closed connections correctly 
We still need to clean up the HNB data structures after the connection
is closed

Harald Welte 1d2c39d83b various cleanups (compiler warnings, coding style) 2015-09-11 17:49:37 +02:00
Harald Welte 10dfc5a97d respond to HNBAP UE REGISTER REQ withe correspnding ACCEPT 
The Accept incudes the IMSI that the phone presented, but
somehow we fail to encode the Context ID as bitstring,  see

Harald Welte b534e5c085 introduce ue_context management 
We keep one 'ue_context' structure for every UE that we see
a UE REGISTER REQUEST for.

Harald Welte 350814a5cb first dispatch of RUA into RANAP 
This is becoming more and more of a hack, as asn1c + asn1tostruct.py
don't really deal well with the RANAP syntax :(
