In the process, also:
* Change the license from AGPLv3 to GPLv2-or-later;
* correct spelling of 'sysmocom' to lowercase;
* add '2016' to the copyright;
* rename to osmo_*;
* add API docs;
* add logging category DLOAP: define id and add to internal_cat;
* redirect all oap.c logging to DLOAP.
A unit test will follow in a subsequent patch, since it needs a minor tweak for
decoding of boolean values.

Add two functions to create USSD messages. Moves and generalizes code from
openbsc. Pending: use the new functions in openbsc.
It looks like _release_complete() should also set trans_id and direction flag;
but since this is moving code from openbsc that is apparently working, just
place a fixme comment and don't change the functionality.

Context: in osmo-bts, I want to look up an RSL message name in rsl_msgt_names
and fall back to rsl_ipac_msgt_names if not found, because the IPAC PDCH ACT
and DEACT messages are sent in a standard ABIS_RSL_MDISC_DED_CHAN.

Move those routines from OpenBSC to libosmogsm, so they can be
re-used from other programs. I think it was a mistake to add them only
inside the openbsc repository in the first place. We need to pay more
attention to this in the future.
|
|
|
|
|
| |
These routines have nothing to do with specifically the BSC, so import
them to the TLV parser we keep in libosmogsm.

Add python utility to generate .c code with convolutional
encoder/decoder based on polynomial description of the code. If argument
given it'll be interpreted as intended output directory, otherwise
current working directory is used.
Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual
implementations are removed from tests. This introduce build-time
dependency on python.
The main work for this patch was generously contributed by Sylvain
Munaut.

For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/
gsm48_decode_lai(). Those functions also handle a trivial extra
member (lac) which I don't need in this way for 3G.
So create new functions to take on the MCC+MNC BCD handling and call those
from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code
in openbsc can use only the BCD functionality without code duplication.

These patches enhance the Supplementary Service (SS) processing from
only being able to handle USSD to other SS, specifically activation,
deactivation and interrogation of those SS. Registration is not yet
implemented.
include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed
values for SS.
Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI
stability.

As we are breaking builds by moving functions from libosmo-abis to
libosmocore anyway, we might as well give functions more appropriate
names. ipaccess is a company, while IPA is the multiplex protocol, and
CCM is the protocol used for establishing identities on the IPA
multiplex.

Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which
makes it more clear that this is an osmcoom specific attribute.
Also, we cannot simply overload 0x01 as an already defined OML
attribute. The problem is quite simple: When we use abis_nm_att_tlvdef
during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL,
which is defined as { TLV_TYPE_FIXED, 3 }.
So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[],
which has to be patched into abis_nm_att_tlvdef[] by the means of
tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific
attributes.
I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA
specific attribues (and we might want to combine/merge the 12.21 plus
IPA plus osmocom spefici attributes)

The 7bit<->8bit encoding/decoding functions didn't check whether
there is still enough space in the destination buffer. Therefore a
buffer size parameter has been added to each of the functions which
is used to truncate the output if the buffer is too small.
In addition, the return value of the decoding functions has been
changed to number of characters written (excluding \0), so this
value is always equal to strlen(decoded).
The old functions are still available as wrapper functions.

Handling 7-bit coding is a little different for USSD, as TS 03.38
states:
To avoid the situation where the receiving entity confuses 7 binary
zero pad bits as the @ character, the carriage return or <CR>
character shall be used for padding in this situation [...].
If <CR> is intended to be the last character and the message
(including the wanted <CR>) ends on an octet boundary, then another
<CR> must be added together with a padding bit 0. The receiving entity
will perform the carriage return function twice, but this will not
result in misoperation as the definition of <CR> [...] is identical to
the definition of <CR><CR>.
The receiving entity shall remove the final <CR> character where the
message ends on an octet boundary with <CR> as the last character.
Jacob has verified the fix with fakeBTS and the wireshark dissector.

This new TLV type is specific to TS 44.318. Contrary to the TvLV type
of TS 08.16/08.18, it has an inverted meaning of the extension (0x80)
bit:
* if the extension bit is not set, 1-byte length
* if the extension bit is set, 2-byte length
Futhermore, it has support for variable-length tags, where the tag part
can be optionally two bytes in length. As this esoteric option hasn't
been seen in the wild yet, we only add encoding support but skip
decoding for now.
