* add libpseudotalloc as super-simplistic talloc replacementHarald Welte2017-05-179-1/+145
| | | | | | | | | | | In tightly embedded builds (--enable-embedded), we want the ability to replace talloc with a very simple heap allocator to avoid the complexity of talloc without modifying all our code that assumes talloc. This will break the hierarchical notion of the allocator, but libosmo{core,gsm,coding,codec} don't rely on that anyway. Change-Id: Ie341034076f242a813f081919dd09d845775ad35

* sercomm: Better integration of driver interfaceHarald Welte2017-05-172-34/+24
| | | | | | | | | We cannot assume a certain UART API like uart_baudrate() which only exists in OsmocomBB. Rather, use generic function prototypes (sercomm_drv_*) which are to be provided by the application / environment to the sercomm core. Change-Id: I01ea3067baf1791000c1a7d537ccce496a1ab1ee

* sercomm: Rename sercomm_lock() to sercomm_drv_lock()Harald Welte2017-05-171-18/+15
| | | | | | | | The user of the code is supposed to provide a "driver" implementing those calls according to the specific target architecture/hardware. This only applies to non-host (i.e. embedded) builds Change-Id: I9a6848f23b70fc32f4de10149d857374f76f000d
* sercomm: remove unrequired helper functionsHarald Welte2017-05-172-15/+0
| | | | | | | | osmo_sercomm_{bind,get}_uart() are not really needed anymore, as sercomm_inst is public and thus the user can access the uart_id member directly. Change-Id: I6d57709c3764036046202f16a26c9eb87426c8d1
* sercomm: Move HDLC related defines into C fileHarald Welte2017-05-172-7/+7
| | | | | | | Those values are not relevant to the sercomm user, only to the implementation and thus can remain inside sercomm.c Change-Id: I5700a45985b7c119c6338932171aae62ee4e2d22

| | | | | | | | Rather than having one global instance, let's permit multiple instances of sercomm to co-exist, with all API functions extended by the instance as first argument. Change-Id: I0f3b53f464b119d65747bcb0be0af2d631e1cc05
* Import sercomm.c from osmocom-bbHarald Welte2017-05-172-0/+404
| | | | | | | | | This imports the file src/target/firmware/comm/sercomm.c from osmocom-bb.git without introducing any modifications. It will not even be built yet, as Makefile integration is intentionally left until it has been adapted to work inside libosmocore. Change-Id: I9ee199381c7b5986a9540d124836cdddd0f66c86

* gsm_04_08: Add missing GSM cause valueDaniel Willmann2017-05-122-0/+6
| | | | | | | | | | | | Table 10.5.157 in 10.5.6.6 of 3GPP TS 04.08 is badly formatted. The first value 0x19 "LLC or SNDCP failure" is in the same line as the heading and has not been included in the struct_value so far. Table 10.5.157 in 10.5.6.6 of 3GPP TS 24.008 fixes this formatting issue and also defines two more values 0x08 and 0x18 which are now added to the struct value_string.

* timer: add osmo_timer_setup()Pablo Neira Ayuso2017-05-0911-22/+26
| | | | | | | | | | | | | | | Add a new function timer function to set up the timer, similar to what we have in the Linux kernel. This patch also converts existing opencoded timer setup in the libosmocore tree as initial client of this new function. This patch implicitly removes function callback passed by reference that defeat compile time type validation. Compile-tested only, but I ran make check that reports success when testing timer infrastructure. Change-Id: I2fa49972ecaab3748b25168b26d92034e9145666

| | | | | | | | | | | | | | | | | | Coverity Scan reported a control flow issue in line 206: CID 166898: Control flow issues (DEADCODE) The second branch of the if statement can not be reached. The purpose of the second if branch was to filter out zero length elements if the header states that it is a non extended speech codec type. This makes no sense, since the header needs at least one byte. This patch removes the second if branch, zero length elements are catched by the already existing zero length check at the beginning of the function Change-Id: I89751fc0d598734c64ef1fdced75b7c4fa77c616
* configure.ac: check for __builtin_cpu_supports call supportVadim Yanitskiy2017-05-081-0/+27
| | | | | | | | | | | | The '__builtin_cpu_supports' is a GCC's built-in function which returns a positive integer if the run-time CPU supports specified SIMD feature and returns 0 otherwise. It is required for further SSE optimization of Viterbi decoder. This change adds a new check, whether compiler supports this call. See /gcc/X86-Built-in-Functions.html at gcc.gnu.org for reference.

* configure.ac: add SIMD detection capabilitiesVadim Yanitskiy2017-05-074-0/+173
| | | | | | | | | | | | | | | | | | | This change adds a check whether compiler supports some SIMD (Single Instruction, Multiple Data) instructions. It is enabled by default, and can be disabled by configure option --disable-simd. The check macro is based on the AX_EXT from autoconf-archive: www.gnu.org/software/autoconf-archive/ax_ext.html And depends on the ax_check_compile_flag macro: www.gnu.org/software/autoconf-archive/ax_check_compile_flag.html Currently only the following SIMD extensions are being checked: AVX2, SSE3, SSE4.1, but adding others is also possible. All found extensions are being defined in the 'config.h' header. Change-Id: Idf8fff984bd936a75c7c307338df88ba4b005817
* core/conv: strip unused memalign() callVadim Yanitskiy2017-05-071-10/+1
| | | | | | | | | The alligned memory allocation is only required for SSE, which is currently unsupported. Moreover, it's better to use dedicated _mm_malloc() and _mm_free() from xmmintrin.h instead, which are introduced by Intel specifically for SIMD computations.

* Fix broken ctrl commandsMax2017-05-031-1/+2
| | | | | | | | | | | Recent changes to libosmoctrl resulted in ctrl comands being broken because local lookup helper returned incorrect value for ROOT_NODE. Note: although this commit seems to fix it for me, I'm still not sure how the logic behind lookup function return values work. Would be nice to get it documented.

* tests/conv: add GSM 05.03 specific testVadim Yanitskiy2017-04-306-5/+355

* Uninitialized variable in ipa_ccm_make_id_resp_from_req()Harald Welte2017-04-271-0/+2
| | | | | | | | | | We are allocating a buffer on the stack without initializing it, and then passing it into ipa_ccm_make_id_resp(). There is no real danger from this, as the buffer is only uninitialized if num_ies is 0, but let's memset() it for good style Change-Id: If5761a47b8cba73ddcc02a88cfa5c87c1970c04e Fixes: coverity CID#167040
