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.

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 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.

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 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 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.

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.

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 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.

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 :(
