* CI: update list of compilers (#2223)Ivan Nardi2023-12-20
| | | | | Try using latest gcc and clang versions. We still care about RHEL7: since handling a RHEL7 runner on GitHub is quite complex, let try to use a similar version of gcc, at least
* Move from PCRE to PCRE2 (#2134)Christian Marangi2023-11-01
| | | | | | | | | | Move from PCRE to PCRE2. PCRE is EOL and won't receive any security updates anymore. Convert to PCRE2 by converting any function PCRE2 new API. Also update every entry in github workflows and README to point to the new configure flag. (--with-pcre2) Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

* Fix compilation with GCC-7 and latest RoaringBitmap code (#1886)Ivan Nardi2023-02-13
| | | | | | | | | | | | | | | | | | | | | | | Latest RoaringBitmap version (introduced with bf413afb) triggers a new warning with GCC-7: ``` ivan@ivan-Latitude-E6540:~/svnrepos/nDPI(dev)$ CC=gcc-7 CXX=g++-7 ./autogen.sh && make -s autoreconf: Entering directory `.' [...] third_party/src/roaring.c:1815:1: warning: ‘no_sanitize’ attribute directive ignored [-Wattributes] static inline int array_container_cardinality(const array_container_t *array) { ^~~~~~ third_party/src/roaring.c:1964:5: warning: ‘no_sanitize’ attribute directive ignored [-Wattributes] const array_container_t *container2) { [..] ``` The core issue is that `no_sanitize` attribute is defined only for GCC >= 8. That breaks the CI since we still use GCC-7 and `-Werror`: add a simple workaround. Fix compilation on Windows

* fuzz: add fuzzer testing nDPI (initial) configurations (#1830)Ivan Nardi2022-12-23
| | | | | | | | | | | | | | | | | The goal of this fuzzer is to test init and deinit of the library, with different configurations. In details: * random memory allocation failures, even during init phase * random `ndpi_init_prefs` parameter of `ndpi_init_detection_module()` * random LRU caches sizes * random bitmask of enabled protocols * random parameters of `ndpi_set_detection_preferences()` * random initialization of opportunistic TLS * random load/don't load of configuration files This new fuzzer is a C++ file, because it uses `FuzzedDataProvider` class (see https://github.com/google/fuzzing/blob/master/docs/split-inputs.md). Note that the (existing) fuzzers need to be linked with C++ compiler anyway, so this new fuzzer doesn't add any new requirements.
* Add support for LTO and Gold linker (#1812)Ivan Nardi2022-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit add (optional) support for Link-Time-Optimization and Gold linker. This is the first, mandatory step needed to make nDPI compliant with "introspector" sanitizer requirements in OSS-Fuzz: see https://github.com/google/oss-fuzz/issues/8939 Gold linker is not supported by Windows and by macOS, so this feature is disabled by default. It has been enable in CI in two linux targets ("latest" gcc and clang). Fix some warnings triggered by LTO. The changes in `src/lib/ndpi_serializer.c` seams reasonable. However, the change in `tests/unit/unit.c` is due to the following warning, which seems to be a false positive. ``` unit.c: In function ‘serializerUnitTest’: ndpi_serializer.c:2258:13: error: ‘MEM[(struct ndpi_private_serializer *)&deserializer].buffer.size’ may be used uninitialized in this function [-Werror=maybe-uninitialized] unit.c:67:31: note: ‘MEM[(struct ndpi_private_serializer *)&deserializer].buffer.size’ was declared here 67 | ndpi_serializer serializer, deserializer; | ^ ndpi_serializer.c:2605:10: error: ‘MEM[(struct ndpi_private_serializer *)&deserializer].status.buffer.size_used’ may be used uninitialized in this function [-Werror=maybe-uninitialized] unit.c:67:31: note: ‘MEM[(struct ndpi_private_serializer *)&deserializer].status.buffer.size_used’ was declared here 67 | ndpi_serializer serializer, deserializer; ``` Since this warning is triggered only with an old version of gcc and `tests/unit/unit.c` is used only during the tests, the easiest fix has been applied. Some (unknown to me) combinations of OS and compiler trigger the following warnings at linker time (with sanitizer and gold linker) ``` /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_load1_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_load2_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_load4_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_load8_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_load16_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_store1_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_store2_asm' /usr/bin/ld.gold: warning: Cannot export local symbol '__asan_report_store4_asm' [..] ``` I have not found any references to this kind of message, with the only exception of https://sourceware.org/bugzilla/show_bug.cgi?id=25975 which seems to suggest that these messages can be safely ignored. In any case, the compilation results are sound. Fix `clean` target in the Makefile in the `example` directory. In OSS-Fuzz enviroments, `fuzz_ndpi_reader` reports a strange link error (as always, when the gold linker is involved...). It's come out that the culprit was the `tempnam` function: the code has been changed to use `tmpfile` instead. No sure why... :( Fuzzing target `fuzz_ndpi_reader.c` doesn't use `libndpiReader.a` anymore: this way we can use `--with-only-libndpi` flag on Oss-Fuzz builds as workaround for the "missing dependencies errors" described in https://github.com/google/oss-fuzz/issues/8939

* configure: fix usage of libgpg-error with `--with-local-libgcrypt` (#1472)Ivan Nardi2022-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, using external libgcrypt, nDPI is not linked to libgpg-error because configure script never checks for it. ``` ivan@ivan-Latitude-E6540:~/svnrepos/nDPI(dev)$ CC=gcc-11 CXX=g++-11 CFLAGS="-O3 -g -Werror" ./autogen.sh --enable-debug-messages --with-pcre --with-local-libgcrypt && make -s -j [...] checking for numa_available in -lnuma... yes checking for pcap_open_live in -lpcap... yes checking for pthread_setaffinity_np in -lpthread... yes checking for gcry_cipher_checktag in -lgcrypt... yes <------- missing check for libgpg-error checking for pcre_compile in -lpcre... yes checking that generated files are newer than configure... done [...] ivan@ivan-Latitude-E6540:~/svnrepos/nDPI(dev)$ grep HAVE_LIBGPG_ERROR src/include/ndpi_config.h /* #undef HAVE_LIBGPG_ERROR */ ``` Make both libgcrypt and libgpg-error mandatory if `--with-local-libgcrypt` is used. Technically speaking, libgpg-error might be optional, because it is used only for debug messages. However having both libraries mandatory slightly simplified the logic. In most environments, libgpg-error is a dependency of libgcrypt anyway, so having both libraries should be the standard case.
