2015-12-24fix build if depenedencies are in distinct directoriesAlexander Huemer6-5/+6
2015-12-24add rua_helper.[ch] missing from previous commitHarald Welte2-0/+166
2015-12-24hnb-test: Add VTY to manually issue Iuh messagesHarald Welte3-26/+231
We can now send Iuh messages with commands like 'hnbap hnb register', 'hnbap ue regiter imsi 12345', 'ranap reset cs', 'ranap reset ps', and even establish connection-oriented RUA using 'channel cs lu imsi 12345'
2015-12-24ranap_msg_factory.c: Fix compiler warningsHarald Welte1-6/+6
2015-12-24ranap_msg_factory: use OCTET_STRING_fromBuf() in ranap_new_msg_dt()Harald Welte1-2/+1
When using asn1c, we cannot use buffers allocated elsewhere and/or on the stack as input into encoding.
2015-12-24ranap: New ranap_new_msg_initial_ue() funcitionHarald Welte3-3/+63
for testing, it is useful if we can also generate an InitialUE message - even though a HNB-GW only needs to receive it.
2015-12-24asn1helpers.h: Add missing declarations of functions in asn1helpers.cHarald Welte1-0/+3
2015-12-24hnbgw_rua.c: Incoming context IDs are 24bit wide according to specHarald Welte1-3/+3
so don't try to decode them to u32, which expects 32bit input values.
2015-12-24RANAP: Replace the last remainng TBCD-STRING with OCTET STRINGHarald Welte3-37/+41
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.
2015-12-24improve logging, remove obsolete FIXMEs, return of non-void functionsHarald Welte2-12/+25
2015-12-24Implement forwarding of RANAP PAGING from CN to all HNBsHarald Welte1-9/+19
2015-12-24hnbgw: Bring all parts togetherHarald Welte12-119/+946
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...
2015-12-23hnbgw_rua: Don't use msgb as imput, allow more parametersHarald Welte2-11/+63
2015-12-23Add a context mapper to map RUA ContextIDs <-> SUA Connection IDsHarald Welte5-13/+294
2015-12-23Introduce DRANAP/DRUA log categories to separate loggingHarald Welte7-23/+35
2015-12-23fix copy/paste mistake in src/Makefile.amAlexander Huemer1-1/+1
2015-12-23use msgb_sctp_ppid() from libosmo-netif, remove local declarationHarald Welte4-5/+7
2015-12-23hnbgw: Add SUA client socket towards localhostHarald Welte4-2/+48
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.
2015-12-23remove sigtran code, now part of libosmo-sccpHarald Welte10-2095/+0
2015-12-22hnbgw: Free msgb when connection is closedDaniel Willmann1-2/+4
2015-12-22hnbgw_hnbap.c: Clean up after encoding a UE register acceptDaniel Willmann1-0/+4
Need to free the ASN.1 structs after using them to encode the UE register accept message.
2015-12-22asn1tostruct.py: Fix memory leaks in generated codeDaniel Willmann1-2/+9
The decode_*ies functions did not clean up after them. This change is taken from changes made to asn1tostruct.py in openair-cn repository.
2015-12-22Remove obsolete ffasn1c files.Neels Hofmeyr6-58879/+0
The ffasn1c files from early trials are obsolete, we're using asn1c now.
2015-12-22really fix src/Makefile.amNeels Hofmeyr1-1/+3
Add BUILT_SOURCES to src/Makefile.am. (And remove a stray space.)
2015-12-22fix Makefile.amAlexander Huemer1-9/+0
2015-12-22README, .gitignoreNeels Hofmeyr2-4/+25
Update building instructions and add tests/atconfig to .gitignore.
2015-12-21SUA: Ensure osmo_ prefix is used on all global symbolsHarald Welte6-50/+51
2015-12-21SUA: More FIXMEsHarald Welte2-2/+3
2015-12-21Add WIP code for SCCP User Adaptation (SUA) and SCCP User SAPHarald Welte10-0/+2093
The idea of this code is to * provide a SCCP User SAP as boundary between the User of SCCP or SCCP-like transport like SUA * implement the minimum subset of SUA to transport RANAP messages betweene HNB-GW and MSC/SGSN At this point * we don't yet implement the proper state machines and timer * we don't imp[lement the SCCP RESET procedure * we don't implement AS/ASP management The code is full of FIXMEs whihc hopefully will get fixed gradually. After some cleanup + verification, it should move to a library, possibly either replacing/renaming libomo-sccp, or adding it to libosmo-netif?
2015-12-21move COPYING file to root directoryHarald Welte1-0/+0
2015-12-21Makefile.am: Try to model the asn1tostruct.py generation dependenciesHarald Welte1-0/+5
2015-12-19add TS 25.412 specHarald Welte3-0/+2
2015-12-19Add various RANAP packet captures (pcap files) found on the netHarald Welte7-0/+0
2015-12-19ranap ASN.1: Define IMSI as OCTET STRING to work around asn1c bugHarald Welte3-37/+41
When IMSI is a TBCD-STRING type, and TBCD-STRING is defined as OCTET STRING, we end up encoding the IMSI the wrong way. I don't knwo why that is, but changing it fixed the problem, as described below: before this commit: 00 17 PeranentNAS-UE-ID 40 criticality ignore 0a (length) 00 presence = IMSI 08 BUG: why the additional length field? 46 23 91 34 70 77 80 f3 IMSI (643219430777083) after this commit: 00 17 PeranentNAS-UE-ID 40 criticality ignore 09 (length) 50 presence = IMSI 46 23 91 34 70 77 80 f3 IMSI (643219430777083)
