* fsm: do not terminate child FSMs earlyPhilipp Maier2018-02-091-3/+4
| | | | | | | | | | | | The function _osmo_fsm_inst_term() terminates all child FSMs befor it calls fi->fsm_cleanup(). This prevnts the cleanup callback to perform last actions on the child FSMs (e.g. osmo_fsm_inst_unlink_parent()). move the function call to _osmo_fsm_inst_term_children() below the call to fi->fsm->cleanup().

* tlv_parser: Report *first* occurrence of repeated IEsHarald Welte2018-02-091-2/+7
| | | | | | | | | | Most GSM related specifications require the receiver to use the *first* occurrence of repeated IEs. The Osmocom TLV parser so far did the opposite: It reported only the *last* occurrence in case of repeated IEs. Let's change our implementation to be more in-line with relevant specs, such as 3GPP TS 24.008 8.6.3. Change-Id: Icde09e075f68c842a7a96cf7160c8e44b77cf82d
* tests: utils_test: Fix test failure when compiling with -O0Pau Espin Pedrol2018-02-081-0/+1
| | | | | | | | | It seems with default flags in_buf was being memzeroed by the compiler. When compiling with -O0, that's not the case anymore and printf prints after first 16 bytes, printing extra garbage which doesn't match the expected output. Change-Id: I736c1e4d625f647d3bb794fa717256e9dbf36e87
* tests: coding_test: Fix compilation with -O0Pau Espin Pedrol2018-02-081-2/+2
| | | | | | | | | | | | | | | | | inline keyword is a hint for the compiler to inline the function, but it's not mandatory. If no static or extern is specified, the definition is only visible in the current unit but the identifier still has external linkage. When running with -O0 it seems the compiler (gcc 7.2.1) decides to use the external linkage but at the same time it seems it's not generating the function symbol. Fix it by explicitly stating that we want to use static linking for this function. coding/coding_test.o: In function `test_xcch': libosmocore/tests/coding/coding_test.c:86: undefined reference to `dump_ubits' libosmocore/tests/coding/coding_test.c:87: undefined reference to `dump_sbits' Change-Id: I18018adec05ce1c2ddbca38653311d74c7454ce8

* vty: fix 'logging print file' outputNeels Hofmeyr2018-02-061-8/+11
| | | | | | | | | | | | | | In If1bd79026a3c680ccf7587d545d12f7759a998fc, an erratic logging output crept in for an earlier patch state and was merged by accident; fix 'logging print file (0|1|basename)' output. Add value string to map LOG_FILENAME_* enum to VTY args, use for both command evaluation as well as printing the vty config. The default is 'logging print file 1', hence we could omit an output when '1' is chosen. But for clarity, always output the current setting. Change-Id: I1c931bff1f1723aa82bead9dfe548e4cc5b685e0

* utils: add helper wrapper for osmo_strlcpy()Max2018-02-052-4/+6
| | | | | | | | | | Add wrapper for osmo_strlcpy() which uses sizeof() to automatically determine buffer's size and use it for GSMTAP logging. This is pretty common use case for osmo_strlcpy() so it's a good idea to save some typing by using generic define. Related: OS#2864 Change-Id: I03d0d3d32a8d572ad573d03c603e14cdc27a3f7b

* socket: use inet_ntop() instead of inet_ntoa() in osmo_sock_local_ip()Philipp Maier2018-01-221-2/+2
| | | | | | | | | | | | | | | The function inet_ntoa() stores its result in a static buffer and returns the pointer. When inet_ntoa() is called subsequently it overwrite the content of its static buffer with the new result. Since we osmo_sock_local_ip() is a library function we should use the more safe variant inet_ntop() in order to prevent unintentionally overwriting data that the caller might still need. Such an error would be hard to find. - Use the more safe inet_ntop() inestead of inet_ntoa() Change-Id: I9852b57736432032542bd96b6fdd4a2f08fc1f64

* tests/ussd: prevent uninitialized memory accessVadim Yanitskiy2018-01-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously an incorrect length value was passed to both gsm_7bit_decode_n_ussd() and gsm_7bit_encode_n_ussd() functions during test_7bit_ussd() execution, due to: octets_written = strlen(decoded); The problem is that a 7-bit encoded string takes less memory than its 8-bit equivalent. So, here strlen() returns one-byte bigger value, that octets_written is. This then causes the uninitialized memory access.

* logging: allow to log only the basename of each sourceNeels Hofmeyr2018-01-192-0/+15
| | | | | | | | | | | In the C API, add another enum log_file_type value, and when set print only the basename of the source file path. Rationale: especially when not building directly in the source dir, the paths to the source files can become rather long. Usually, just the basename of the file is sufficient to identify the source line. Change-Id: If3e4d5fb2066f8bf86e59c82d1752b1a843cf58e
* logging: separate the '<000b>' subsys from filename loggingNeels Hofmeyr2018-01-193-7/+74
| | | | | | | | | | | | | | | | | | | Add a separate flag and API to switch the category-in-hex output: log_set_print_category_hex(). Add log_set_print_filename2() to modify only the print_filename flag. The old log_set_print_filename() function still affects both flags. Explain the rationale in the comment for log_set_print_filename(). There is no need to deprecate log_set_print_filename(); it might cause compiler warnings and break strict builds unnecessarily. Add VTY command 'logging print category-hex (0|1)'. Since there is no VTY command to switch filename output, nothing needs to be adjusted there (a command will be added in a subsequent patch).

* cosmetic: logging: if color is disabled, don't print ""Neels Hofmeyr2018-01-171-5/+6
| | | | | | | | | | | | If color output is disabled, skip the empty snprintf() to (not) clear the ANSI color. Also, no need to use a format string of "%s", just pass the string constant directly.

* fix -Werror build: logging.c: always use literal with snprintfNeels Hofmeyr2018-01-171-1/+1
| | | | | | | | | | | | | | | | | | A recent commit added an snprintf that passes a pointer to a literal directly to snprintf. Since passing pointers to printf formats is a vulnerability in case user supplied data may be passed in the format, modern compilers warn against that, which breaks our -Werror builds. Even though this is just a pointer to a literal, it needs to be an actual literal to make compilers happy. Use printf("%s", c) instead of printf(c). Note that our current build slave's gcc does not enforce that yet, while newer compilers do. logging.c:338:4: warning: format not a string literal and no format arguments [-Wformat-security] ret = snprintf(buf + offset, rem, c_subsys); Change-Id: Ifa4eb8a9fab66dcd987986065351b4a06421f1ec
