The definitions in this header file (and associated strings in the
c file) are generic about the GPRS Layer3 signalling protocols, and
thus should be part of the library.

The script does not work with python3:
$ python3 utils/conv_gen.py
File "utils/conv_gen.py", line 124
def _print_term(self, fi, num_states, pack = False):
Second there is no 'python' on FreeBSD and one needs to select
the major version to use.
GEN conv_cs3_gen.c
GEN conv_xcch_gen.c
GEN conv_cs2_gen.c
python: not found

By using python2 we solve both issues. On Debian python2 is located
inside the python-minimal package.

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.

Shipping our own private copy of talloc was a good idea in 2008,
when it was not readily available on most target platforms. Today,
the situation is quite different, as it is a standard library on
major Linux distributions.

When using configure --disable-static, no libosmogsm.a will be
created, and the tests fail to link because symbols like _a5_3 and
_a5_4 are not exported through the only remaining libosmogsm.so.
A method to overcome this is an intermediate private non-distributed
library, examples of which are present in e.g. libabc, kmod and
systemd.
With this, disable-static can now be the default and practical compile
time be halved.

The current functions are used to 'qualify' an APN from the
user-supplied APN name (name identifier) towards the fully-qualified
APN name which is used in the .grps DNS zone.

Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the

the bits/crc files are not inside the sourcedirectory but will end
in the build directory. Go and look there as well. This somehow
doesn't fail with make distcheck but when building for Yocto Dizzy.

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.

libosmo-abis is about forming A-bis interfaces/lines by means
of E1 or the IPA multiplex (or possibly other link layers).
The IPA multiplex is used in other contexts, such as the Control
interface, or the A interface. In that context, it makes sense to
have generic IPA related functions in libosmocore.

Only the Gb library relies on having undefined references to a
symbol that needs to be provided by the host application. For
all other libraries we can link with -no-undefined.

This actually allows for the user to override the decision and at the
same time supports compilers that might not be able to use -fPIC at
all.

There is now a "libosmogsm.map" file containing an explicit list of
to-be-exported symbols. This should prevent us from leaking non-static
symbols into the global namespace.
A similar scheme should be adopted by all other osmocom libraries
|

|
| |
|
|

... and add integration into the osmo_auth core.

Indiidual algorithms can be implemented as plugins. libosmogsm itself
only provides COMP128v1 via this generic interface.

The SMR process is used to transfer SMS TPDUs. It is now extracted from
OpenBSC. It includes a real state machine now for easier debugging.
Also it implements the TR1M and TR2M timers. The memory notification
procedure is missing, but not required for network side.

Instead of mixing together the GSM layer 1 interface and RSL interface
with the implementation of LAPD, the core function of LAPD is now
extracted from LAPDm. The core implementation is now in lapd_core.c
and lapd_core.h respectively.
The lapd_core.c implements exactly one datalink instance for one SAP.
The surrounding implementation "lapdm.c" codes/decodes the layer 2
headers and handles multiplexing and datalink instances, as well as
translates primitives from/to RSL layer.
lapd_core.c can now be used for other LAPD implementations. (ISDN/ABIS)

I have also moved generate_backtrace() to backtrace.c instead
of gsm_utils.c, otherwise the timer and msgfile tests depend on
libosmogsm.
