and even establish connection-oriented RUA using
'channel cs lu imsi 12345'

Harald Welte f9c9aa5f20 ranap_msg_factory.c: Fix compiler warnings 2015-12-24 15:39:00 +01:00
Harald Welte 57d873392c ranap_msg_factory: use OCTET_STRING_fromBuf() in ranap_new_msg_dt() 
When using asn1c, we cannot use buffers allocated elsewhere and/or on
the stack as input into encoding.
 2015-12-24 15:33:21 +01:00
Harald Welte ea98b6f6d6 ranap: New ranap_new_msg_initial_ue() funcition 
for testing, it is useful if we can also generate an InitialUE
message - even though a HNB-GW only needs to receive it.
 2015-12-24 15:09:06 +01:00
Harald Welte afcaac08ee asn1helpers.h: Add missing declarations of functions in asn1helpers.c 2015-12-24 15:03:11 +01:00
Harald Welte b0de90639b hnbgw_rua.c: Incoming context IDs are 24bit wide according to spec 
so don't try to decode them to u32, which expects 32bit input values.
 2015-12-24 14:10:17 +01:00
Harald Welte c89c2a6e6a RANAP: Replace the last remainng TBCD-STRING with OCTET STRING 
in order to work around a bug in asn1c.  When we keep the original
TBCD-STRING, the APER-encoded PLMNidentity always has an extra leading
length byte that the decoder doesn't expect.

Harald Welte 37166a27ca improve logging, remove obsolete FIXMEs, return of non-void functions 2015-12-24 10:12:09 +01:00
Harald Welte bc4560cf18 Implement forwarding of RANAP PAGING from CN to all HNBs 2015-12-24 08:46:58 +01:00
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 cd5e981490 hnbgw_rua: Don't use msgb as imput, allow more parameters 2015-12-23 22:14:16 +01:00
Harald Welte 90256bad58 Add a context mapper to map RUA ContextIDs <-> SUA Connection IDs 2015-12-23 22:13:53 +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.

register accept message.
 2015-12-22 16:40:46 +01:00
Daniel Willmann d174e76f1d asn1tostruct.py: Fix memory leaks in generated code 
The decode_*ies functions did not clean up after them. This change is
taken from changes made to asn1tostruct.py in openair-cn repository.
 2015-12-22 16:40:46 +01:00
Neels Hofmeyr 8aac21a5e8 Remove obsolete ffasn1c files. 
The ffasn1c files from early trials are obsolete, we're using asn1c now.
 2015-12-22 13:02:42 +01:00
Neels Hofmeyr c51f735b35 really fix src/Makefile.am 
Add BUILT_SOURCES to src/Makefile.am.
