* Fix embedded (arm-none-eabi) buildsHarald Welte2018-06-281-0/+2
| | | | | | | | | Due to OS#3360, build testing for arm-none-eabi was unfortunately skipped for a long time. This is a number of fixes that make the compile test pass again. Related: OS#3360 Change-Id: I88e3c8e1a8786ca2a6a023b0d27c74be200a8588
* ctrl: Add doxygen API documentation; generate html from itHarald Welte2018-05-261-0/+1

* ctrl: Introduce libosmoctrl.map to avoid unintended exportsHarald Welte2018-05-261-0/+2
| | | | | | | | There are some symbols for use between control_cmd.c and control_if.c, which are not supposed to be exported publicly. Let's make sure we keep those symbols local. Change-Id: Ia85f36a9c4b2ebf4003718e0a230959638370320
* Add osmo_timerfd_* functions for osmo_fd-wrapped timerfdHarald Welte2018-05-101-1/+1
| | | | | | | | | | | | | | | Linux offers file descriptor based periodic (interval) timers, which can achieve a higher precision than our userspace based timers and which can be slave'd to CLOCK_MONOTINIC or other clock sources. Let's add some code for osmo_fd wrapped versions that integrate well with our select() abstraction. The code has been used in osmo-bts-trx since June 2017 (change-id I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming and moving it to libosmocore here. After a merge, the osmo-bts implementations can be removed in favor if this one. Change-Id: Ibeffba7c997252c003723bcd5d14122c4ded2fe7
* configure: Check separately for lib implementing dlopen and dlsymPau Espin Pedrol2018-05-041-2/+4
| | | | | | | | | | Sometimes the library probiding dlopen is not the same one providing dlsym. This is the case when compiling with AddressSanitizer enabled. In this case, AC_SEARCH_LIBS([dlopen]...) reports no lib is required, but tests using dlsym still require to link against -ldl. Change-Id: Ic619b0885688066b60c97caf1e2c7e5402c1d9f7
* configure: add --enable-werrorNeels Hofmeyr2018-03-131-0/+21
| | | | | | | | | | | | | | | | | Provide a sane means of adding the -Werror compiler flag. Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"', but that actually *overwrites* all the other CFLAGS we might want to have set. Maintain these exceptions from -Werror: a) deprecation (allow upstream to mark deprecation without breaking builds); b) "#warning" pragmas (allow to remind ourselves of errors without breaking builds) As a last configure step before generating the output files, print the complete CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

* Embedded: add sercomm stubsMax2018-01-211-0/+2
| | | | | | | The sercomm functions are unavailable in case of embedded build. Add stub and link the tests against it. Change-Id: I9bc5cb2f822b1a3ffdc6ec29f46b6bac8288314e
* Embedded: disable stats testMax2018-01-211-0/+4
| | | | | | | | As of 67bdd80a96bdfc49d1aadbd32cca2b53f123d180 the stats.c is effectively disable so we should disable the corresponding tests as well. Change-Id: I42ff7a6619c0a5926fdc2ec779cf04689c567e15
* conv_acc: Our code requires SSSE3, not just SSE3Harald Welte2017-11-171-1/+1
| | | | | | | | | | | | | | | The accelerated convolutional decoder uses SSSE3 instructions such as PSIGNW (via _mm_sign_epi16) which go beyond what SSE3 offers. So let's make sure we use the right compiler flag (-mssse3) and also the right runtime check. Without this patch, we would use illegal instructions e.g. on Opteron Gen3 such as Opteron 2427, which are also used as build.opensuse.org build hosts (build31 through build36) where we wouldn't pass "make check" as a result. Change-Id: I2754164384109f2821fd98ffb48f625893f2923d Fixes: OS#2386
* Enable GnuTLS fallbackMax2017-11-021-0/+17
| | | | | | | | | | | | | | | | On systems with GNU/Linux kernel older than 3.17 (Debian 8 "jessie" for example) the osmo_get_rand_id() would always return failure due to missing getrandom() syscall. To support such systems, let's add fallback code which uses GnuTLS library. It can be disabled explicitly via '--disable-gnutls' option at compile-time, otherwise ./configure will fail if both getrandom() and GnuTLS are not available. When building with '--enable-embedded' the fallback is disabled automatically. Related: OS#1694 Change-Id: Ic77866ce65acf524b768882c751a4f9c0635740b
* Add function to generate random identifierMax2017-10-091-0/+3
| | | | | | | | | | | | | | | | | The function is a wrapper on top of getrandom() (if available via glibc) or corresponding syscall. If neither is available than failure is always returned. It's intended to generate small random data good enough for session identifiers and keys. To generate long-term cryptographic keys it's better to use special crypto libraries (like GnuTLS for example) instead. As an example it's used to replace old insecure random number generator in osmo-auc-gen utility. Change-Id: I0241b814ea4c4ce1458f7ad76e31d390383c2048 Related: OS#1694
* Makefile.am: fix missing LTLDFLAGS for libosmocodingVadim Yanitskiy2017-08-311-0/+1
| | | | | | | | Despite the libosmocoding.map is preset since the library release, one was not used in a proper way. The LTLDFLAGS were missing, so let's add them. Change-Id: Idf677825ff642d50bea43c7f970810783e864fdd
* Add release target to MakefileMax2017-08-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add simple helper target to automate basic release steps: * version bump * prepare release commit * git commit, tag and sign For library projects: * update debian/changelog from TODO-RELEASE * cleanup TODO-RELEASE For non-library projects: * update debian/changelog from git log Note: it requires bumpversion package to be installed, debian/control is adjusted accordingly. The helper itself is installed to facilitate reuse by other libraries. N. B: you still have to manually adjust LIBVERSION in previous commit - see TODO-RELEASE header for details. Use it as follows: make REL=minor release The REL parameter defines which component of the version [1] to bump and can be any of { major, minor, patch }.

* configure.ac: Add --disable-doxygen flagPau Espin Pedrol2017-07-061-1/+7
| | | | | | | This flag, when set, allows to unconditionally disable doxygen documentation generation, even if doxygen command is found. Change-Id: Iba1440292116af27b267c7a1fbec1c2336784efe
* configure.ac: Fix C(PP)FLAGS for BSD buildPau Espin Pedrol2017-06-231-4/+4
| | | | | | | | | | | | | | If we pass CFLAGS params to configure, then the CFLAGS set inside configure.ac are not applied and the build fails if -Werror is enabled because then BUILDING_LIBOSMOCORE is not defined. Seeing the following output at configure time in FreeBSD build: ./configure: CFLAGS+= -fsanitize=address -fsanitize=undefined: not found ./configure: CPPFLAGS+= -fsanitize=address -fsanitize=undefined: not found ./configure: CFLAGS+= -DBUILDING_LIBOSMOCORE -Wall: not found ./configure: CPPFLAGS+= -DBUILDING_LIBOSMOCORE -Wall: not found Change-Id: I692bbc66e5343998eec360a02a3a1fe73478c5c6

* Fix compilation warning on deprecated macroPau Espin Pedrol2017-06-181-0/+3
| | | | | | | | | A warning was printed even if the deprecation didn't apply to libosmocore because it is still allowed to use it internally. This patch fixes this case while still printing a warning if external projects build using libosmocore headers. Change-Id: I32212f20756f828af1017482a71e29e4b3adbad4
* add libpseudotalloc as super-simplistic talloc replacementHarald Welte2017-05-171-0/+10
| | | | | | | | | | | 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
* 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 Yanitskiy2017-05-071-0/+16
| | | | | | | | | | | | | | | | | | | 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
* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | There are some projects, such as GR-GSM and OsmocomBB, which would benefit from using one shared implementation of GSM 05.03 code. So, this commit introduces a new sub-library called libosmocoding, which (for now) provides GSM, GPRS and EDGE transcoding routines, migrated from OsmoBTS. The original GSM 05.03 code from OsmoBTS was relicensed under GPLv2-or-later with permission of copyright holders (Andreas Eversberg, Alexander Chemeris and Tom Tsou). The following data types are currently supported: - xCCH - PDTCH (CS 1-4 and MCS 1-9) - TCH/FR - TCH/HR - TCH/AFS - RCH/AHS - RACH - SCH Change-Id: I0c3256b87686d878e4e716d12393cad5924fdfa1
* configure.ac: Disable PCSC related code on EMBEDDEDHarald Welte2017-01-151-0/+1
| | | | | | | The EMBEDDED conditional is used for building inside 'bare iron' embedded devices like OsmocomBB phones. There's no PC/SC in them. Change-Id: I2ef7561d7fdb1ef1c060f8ac73d8588fc0f8eb3f

* build: make check: disable sim_test when built with --disable-pcscNeels Hofmeyr2016-11-161-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Numerous issues caused sim_test to be attempted even though libosmosim was not built: In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported. Furthermore in configure.ac, no value 'yes'/'no' was assigned to the ENABLE_PCSC variable, only to the enable_pcsc value. In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have no effect, regardless (not even when using a variable that should be defined accurately). So fix with these steps, similarly to how we do it in openbsc: In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'. Export the same using AC_SUBST(). Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add atlocal to AC_OUTPUT and distclean). Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to indicate skipping the test if enable_sim_test isn't 'yes'. Change-Id: I9e8740c7d2dfbd272e22fee85972ef3fda7184a8
* configure: add --enable-sanitize, use in jenkins.shNeels Hofmeyr2016-10-121-0/+12
| | | | | | | | | | | | | --enable-sanitize adds address sanitizer CFLAGS/CPPFLAGS to the entire build. Also pass UBSAN_OPTIONS to the test suite run (only has effect during runtime). Add this flag to jenkins.sh's configure step. To ensure that we get the sanitize results, add 'make check' to jenkins to catch sanitize failures; Keep 'make distcheck' without ASAN; it has its own configure which omits --enable-sanitize. This way we test both with and without ASAN. Change-Id: Idf7f46fa048608c2951f2473cb528f6c8dc2681d

To reproduce the error avoided by this patch: rm install-sh # in case it was already generated. touch ../install-sh # yes, outside this source tree autoreconf -fi This will produce an error like ... configure.ac:16: error: required file '../ltmain.sh' not found configure.ac:5: installing '../missing' src/Makefile.am: installing '../depcomp' autoreconf: automake failed with exit status: 1 See also automake (vim `which automake`) and look for 'sub locate_aux_dir'.

* configure: check for pkg-config presenceNeels Hofmeyr2016-08-091-0/+15
| | | | | | | | | | | On a fresh installation, I was puzzled by a configure.ac 'syntax error' for PKG_CHECK_MODULES(TALLOC). It took me some time to figure out that merely pkg-config was missing. Add a check for pkg-config, which isn't as straightforward as I would wish, so comment generously. Change-Id: I2e7cdc37eb59f9947a45fbc5baddbaf71b655bc0
* remove our internal copy of talloc, use system libtallocHarald Welte2015-12-051-53/+2
| | | | | | | 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.
* configure: It should be --with-system-talloc, not --enable-system-tallocHarald Welte2015-11-211-8/+8
| | | | | | As we are making a decision whether we should use an existing system library, we call it --with-system-talloc, rather than --enable-system-talloc.

* use system-wide libtalloc with --enable-system-tallocHarald Welte2015-11-211-1/+44
| | | | | | | | | This introduces a new configure flag by which the libosmocore-internal talloc code is not compiled, but rather a system-wide libtalloc is used. When we started openbsc/libosmocore in 2008, libtalloc was not widely present on systems yet. This has changed meanwhile, and we should simply use the system-wide library
* build: have a disable-static build succeedJan Engelhardt2015-09-161-1/+1
| | | | | | | | | | | | | 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.
* build: Enable subdir-objectsSylvain Munaut2015-08-191-1/+1
