* Introduce osmo_strlcpy() function so we can stop using strncpy()Harald Welte2016-11-261-0/+22
| | | | | | | | | | | | | | | | I'm aware of the existing criticism on stlrcpy(), but I think it is still better than what we have now: stnrcpy(), sometimes with Coverity warnings and sometimes with a manual setting of the termination byte. The implementation follows the linux kernel strlcpy() which is claimed to be BSD compatible. We could of course link against libbsd on Linux instead, but I think it's reasonably small and simple to provide our own implementation. Future versions of libosmocore could use some autoconf magic and preprocessor macros to use the system-provided strlcpy() if it exists. Change-Id: Ifdc99b0e3b8631f1e771e58acaf9efb00a9cd493
* osmo_gsup_encode(): Make coverity happy by invariant checkingHarald Welte2016-11-261-0/+1
| | | | | | | | | gsm48_encode_bcd_number() can theoretically return a length in excess of the size of the bcd_buf, but only in case an overly-long IMSI is passed into the function (which would be illegal in the first place).

* bitcomp: Remove the t4 decoding from libosmocoreHolger Hans Peter Freyther2016-11-101-128/+0
| | | | | | | | | | | | As outlined by mail on the 13th of July the tree based approach to decoding in the PCU is faster by order of magnitude. Instead of having a slow implementation in the library and a quick one in the PCU, let's only have a quick one in the PCU and at some point in the future move it to libosmocore. Execute the plan and remove t4_decode. Change-Id: I021424444625a097560d086c217c81eac4a5ee44

* utils/conv_gen.py: generate a single fileVadim Yanitskiy2016-10-231-7/+5
| | | | | | | | | | | | | | | | Instead of generating every convolutional code into a separate file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to have a single file, containing all definitions, because as many convolutional codes we add, as many entries we will have to add into 'src/gsm/Makefile.am'. This approach increases readability of the Makefile.am, and also makes us able to share some data between some convolutional code definitions. For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use the same *_state[][2] and *_output[][2] arrays within a single file. This optimization is currently WIP.

* fix USSD: SS message type mask should be 0x3f, not 0xbfNeels Hofmeyr2016-10-121-1/+1
| | | | | | | | | | | | | | See 04.80[1], section 3.4: the highest two bits are used as counter or ignored and do not contribute to the SS "Miscellaneous message group". Previous mask of 0xbf included the highest bit, fix to 0x3f. Observed a value of 0xbb that should mean 0x3b="Register" during testing of 3G USSD requests, which seem to be the first to send a nonzero highest bit to our code. The erratic mask of 0xbf lead to an unhandled message type of 0xbb. [1] 3GPP TS 24.080 version 7.2.0 Release 7 / ETSI TS 124 080 V7.2.0 (2006-09) Change-Id: I299001a9e36c16f55622a0acd5d4a55ca49d0055
* osmo_select_main(): drop useless call to osmo_timers_check()Neels Hofmeyr2016-09-281-2/+0
| | | | | | | osmo_timers_check() does nothing more than counting the active timers. It is of no use to count them when not using the return value in any way. Change-Id: I8d35ca90a4c16d6f1c7f9793d663e5479783efed
* msgb: add msgb_talloc_ctx_init(), deprecate msgb_set_talloc_ctx()Neels Hofmeyr2016-09-271-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far each and every main() scope creates a msgb talloc context and either passes it to msgb_set_talloc_ctx() or sets tall_msgb_ctx directly (by defining it extern first). Remove some code duplication: add one central function that creates the "msgb" talloc context for all. Most users of msgb employ a talloc_named_const(), but osmo-bts uses a talloc_pool() instead. Offer both ways by means of the pool_size argument, and for both ways make sure the context is called "msgb". Suggest that msgb users should move to this new function: deprecate msgb_set_talloc_ctx(). To be able to do so, include core/defs.h in msgb.h. There's a tradeoff between hiding the msgb talloc context behind API that tries to guess all use cases versus avoiding code dup. This patch opts against code dup and boldly assumes that all future use is covered. Also, the new function suggests to not access tall_msgb_ctx directly, which can be considered a style improvement. It seems that not all main scopes that use msgb actually initialize the msgb ctx. As a fallback for these, explicitly initialize tall_msgb_ctx to NULL.
