Its my 1st mail to the list. I m doing research on osmocom-bb from couple of days. Still m unable to understand what this software EXACTLY do. i.e. what are its applications. Can anyone help me out or share a much useful link which will help me understand the use/applications of this software? I'll be greatful

[PATCH] Add generic LE/BE load/store uint type convertors and use them in msgb
by ☎ 10 Mar '14

10 Mar '14

Attached is simple patch which adds little-endian & big-endian macro to move bytes to and from multibyte integer types like uint16_t, uint32_t etc. Some of this code is used right away in msgb.h but it will also be used in kasumi implementation later on. -- best regards, Max, http://fairwaves.ru

[PATCH] RFC - change GPRS cipher API
by ☎ 07 Mar '14

07 Mar '14

Hello. Attached is a trivial patch which breaks existing GPRS cipher API of libosmocore by switching from fixed 64-bit length Kc to variable-length. There are several justifications for that: - compliance with ETSI TS 155.22 (GEA4 - 128 bits Kc) and all further versions - similarity to existing auth api (osmocom/crypt/auth.h uses 128 bits as well) - nobody uses this API anyway (except my other patches with GEA) - patch breaks nothing within libosmocore (make check succeeds) and openbsc (uses gea0 only) That's why I think next libosmocore version should apply this patch and change unused API before someone actually start using it and makes transition more difficult. -- best regards, Max, http://fairwaves.ru
