Harald Welte 462db35426 hnbap_common: Fix copy+paste mistake (use hnbap msgb allocator) 2015-12-16 23:06:59 +01:00
Harald Welte d328c1a3ac WIP: add some early code for generating required RANAP messages 2015-12-16 23:04:21 +01:00
Harald Welte c16117a22c Add ranap_generate_outcome() function 
Ranap has not only successsful and unsuccessful outcome, but also
an unqualified general 'outcome'.

Harald Welte 8dacb07baf {hnbap,rua,ranap}_common.c: Reduce code duplicatioon 
There used to be a lot of code duplication between the code to generate
initiating, successfulOutcome and unsuccessfulOutcome messages.  Try to
reduce that by callign a generic function.

Harald Welte cbaaeefe00 {rua,hnbap,ranap}_common: Add missing encoding functions 
We used to only have those generator functions that we needed for
the existing hnbgw code; Implement the missing encoders
 2015-12-16 20:17:26 +01:00
Harald Welte 08d5da6647 hnbgw: Use the now-compiling RANAP encoder+decoder code 
So far, we copy-pasted/cherry-picked individual encoder/decoder
functions as the overall ranap_{encode,decode} didn't compile yet.

As the latter is now finally compiling, we can remove those copies and
link in ranap_{encode,decode}.o

Harald Welte 49695572ba One further RANAP hacking session 
This is not development, it is random trial and error hacking.  I really
hate the fact that we have no useful asn.1 code generator and need to
work with hacks like asn1tostruct.py and asn1c without information
object classes :/

This commit is a one-day-long iteration of trial+error, manually editing
and adding the .asn source of RANAP until we get something that in the
end at least compiles and links.  Do I trust the resulting code? No.
But we have no alternative :(

Harald Welte a0c74240fa asn1tostruct: Avoid erroneous double-underscores 
We shouldn't generate names like
RANAP_RAB_SetupList_EnhancedRelocCompleteReq__t when creating the
_encode() and _decode() functiosn, as the '-IEs' at the end must be
stripped before converting all '-' to '_'.

Harald Welte 1c4d4bc233 Make .gitignore aware of autoconf artefacts 2015-12-16 13:17:22 +01:00
Harald Welte 1989913ba2 RANAP: Add more types/IEs to RANAP-PDU.asn and re-generate C 
As asn1c cannot understand information object classes, we cannot compile
RANAP-PDU-Contents.asn but instead need to manually add the respective
infrmation elements to RANAP-PDU.asn.

Harald Welte fd5db064cb Re-add the 'regen' targets lost in the automake transition 
This might need a lot of cleanup for out-of-source-tree builds and the
like, but let's not spend time on this now.  The old Makefile also
didn't support that.  But loosing the ability to regenerate the C source
is not an option either.
 2015-12-16 13:14:10 +01:00
Harald Welte 3297dbaaa7 rename ASN_MODULE_FILES to ASN_MODULE_SOURCES 
... brings us closer to the Makefile.am.sampl generated by asn1c,
facilitating copy+paste.

Daniel Willmann 29b9e00355 Autotoolize the build 
Use Autoconf/make for building and autotest for tests

Daniel Willmann a7b02405be hnb-test: Parse UE register accept 2015-12-14 10:37:26 +01:00
Daniel Willmann 9224731379 asn1helpers: Fix 24 bit conversion function and use it in hnbgw_hnbap 
The 32 bit int needs to be shifted left one byte so the correct bytes
end up at the beginning of the bit string buffer.
 2015-12-14 10:36:36 +01:00
Daniel Willmann 4e31250367 hnb-test: Send UE register request 2015-12-14 10:36:36 +01:00
Daniel Willmann 479cb300ce hnb-test: Send HNB register request and parse the accept 2015-12-14 10:36:36 +01:00
Daniel Willmann 4abdee0803 hnb-test: setsockopt SCTP_EVENTS is needed to get the sctp_sndrcvinfo 2015-12-14 10:36:36 +01:00
Daniel Willmann d6a45b402c asn1helpers: Add 28 bit conversion function and use it for Cell ID 
The padding bits in the bit string are at the end and the byte-order is
MSB-first. This means the number needs to be shifted left so the padding
bits are the least significant.

Daniel Willmann 0e8ef67b7a hnbap_common: Add function to HNBAP generate initiating message 
An earlier version was commented out, this function now works like
hnbap_generate_successful_outcome()

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.

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 9614d9aea7 add more relevant/related specs 2015-10-07 15:59:45 +02:00
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.

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.
