 2015-12-03 09:37:58 +01:00
Daniel Willmann 56f6273430 hnbgw: Add VTY commands to show info about connected HNBs and UEs 2015-12-02 12:58:42 +01:00
Daniel Willmann 9a12a4b992 test-helpers: Also print out hexdump of encoded bit string 2015-11-30 16:27:11 +01:00
Daniel Willmann b2548fb1e8 asn1helpers, test-helpers: Use ntoh/hton* to convert integers 
Since the asn1_u32/24_to_bitstring functions need to change the source
variable change the signature to clarify that the uint32_t * will be
modified.
 2015-11-30 16:24:57 +01:00
Daniel Willmann e2956431e8 test-hnbap: Check CID and Identity Info as well 2015-11-30 16:05:51 +01:00
Daniel Willmann 23c86e38bc test-hnbap: Use different types for UE request and accept IEs 2015-11-30 16:03:36 +01:00
Daniel Willmann e3adf0edc3 asn1helpers: Fix asn1str_to_uX functions 
The values are stored big-endian so convert them
 2015-11-27 17:53:19 +01:00
Daniel Willmann ea4c088e78 test-hnbap: Test decoding of the hnbap registration request

Daniel Willmann 8ea918d772 tests: Test cropping of string still is NULL-terminated 2015-11-23 15:59:02 +01:00
Daniel Willmann 53018e937c asn1helpers: Ensure that string is NULL-terminated 
The buf in an OCTET_STRING_t is not (necessarily) NULL-terminated, so
make sure there is a terminating NULL byte at the end in the resulting
string.
 2015-11-23 15:55:46 +01:00
Daniel Willmann ec0e50e148 tests: Test asn1_strncpy function 2015-11-23 15:48:59 +01:00
Daniel Willmann 6e59d413a2 asn1helpers.c: Fix asn1bitstr_to_u32 function 
The value in buf is kept in host byte order so no need to swap it
around.
 2015-11-23 14:03:04 +01:00
Daniel Willmann 54a9a143f0 tests: Test asn1_u32_to_bitstring and asn1bitstr_to_u32 2015-11-23 14:02:38 +01:00
Daniel Willmann cc5f7cafa2 src/Makefile: Change order of dependencies so a clean checkout builds 
There still seem to be some issues with the _decode.o dependencies, but
this will eventually build through.
 2015-11-20 19:52:00 +01:00
Harald Welte 0bb1261239 add asn1_u24_to_bitstring() 
Sometimes we have a native uint32_t, but we don't want to encode
it to a 4-byte long ASN1 BITSTRING, but rather to one that is only
24 bits.
 2015-10-06 22:08:54 +02:00
Harald Welte 4dd16b9643 make asn1bitstr_to_u32() work for sub-32bit bit-strings 
IF the ASN1 Bit-string is only 24 bits or even less long,
we might still want to retrieve it as an uint32_t.
 2015-10-06 22:08:10 +02:00
Harald Welte 77847ad020 add copyright statement and AGPLv3 headers to source code files 2015-10-06 22:07:04 +02:00
Harald Welte 6286880caa the Context ID is a 24bit number, we cannot use len = 4 bytes! 2015-09-18 01:23:55 +02:00
Harald Welte 1c2ada0e7f ranap: receive/parse DirectTransfer 2015-09-11 20:10:17 +02:00
Harald Welte 80401adcb0 ranap: Parse InitialUE message and hex-print NAS PDU 2015-09-11 19:48:06 +02:00
Harald Welte 0f0ea8112f RUA: hand off RANAP from all PDU types, not just UnitDataTransfer 
Also, we now offer a ranap_tx_dt() message for connection-oriented
RANAP transfers.  A far as I understand the RUA spec, on RUA layer,
all operations are Class 2, i.e. without any response/confirmation.
 2015-09-11 18:58:28 +02:00
Harald Welte cc27bebd30 ranap: prepare decoding of InitialUE message 2015-09-11 18:45:39 +02:00

Harald Welte 3af1db87ed hnbap: Print error messages in error cases 2015-09-11 17:03:16 +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
../pcap/20150911-hnbap-ue_register.pcap
 2015-09-11 01:36:44 +02:00

Harald Welte b534e5c085 introduce ue_context management 
We keep one 'ue_context' structure for every UE that we see
a UE REGISTER REQUEST for.
 2015-09-11 00:15:54 +02:00
Harald Welte e2e5d4dd53 Back RUA/RANAP integration until RANAP Reset works for cs+ps 
The hNodeB is now actively transmitting and we are getting up to the
HNBAP UE-REGISTER.req with the IMSI of the MS.
 2015-09-10 23:49:45 +02:00
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 :(
 2015-09-10 22:32:15 +02:00
Harald Welte ac9c024432 ranap: Add more manual definitions to RANAP-PDUs 
It seems that individual IEs contain nested containers, and
asn1c is not generating code for that unless we help it by some
hand-crafted additional definitions. *sigh*
 2015-09-10 21:18:16 +02:00

Harald Welte 2204f9d43d hnbgw: zero-initialize the output struct before aper_decode()

zero-initialized.
 2015-09-07 22:25:35 +02:00

Harald Welte d523a69dbe import ans1c generated C sources for HNBAP 
TODO: split the HNBAP specific code from the core runtime code
and use libosmo-asn1c instead.  This is required as we will be

executable.
