2018-02-15fsm: Add a function to change the FSM instance ID laterDaniel Willmann1-0/+2
Sometimes we want to create an FSM instance before we know its name. In that case we should be able to update the id later. Change-Id: Ic216e5b11d4440f8e106a297714f4f06c1152945

2018-02-05utils: add helper wrapper for osmo_strlcpy()Max1-0/+3
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

2018-01-19logging: allow to log only the basename of each sourceNeels Hofmeyr1-0/+1
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
2018-01-19logging: separate the '<000b>' subsys from filename loggingNeels Hofmeyr1-1/+13
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). Change-Id: Iba03a2b7915853c6dccaf6c393c31405320538b4
2018-01-17logging: add ability to log the log-level with API and vtyNeels Hofmeyr1-0/+4

2018-01-17gsm0480: fix USSD OCTET STRING length confusionVadim Yanitskiy1-2/+22
According to the GSM 04.80 (version 5.0.0) specification Annex A "Expanded ASN.1 Module "SS-Protocol", the maximum size of a USSD OCTET STRING is 160 bytes. Thus according to ETSI TS 123 038 (version 10.0.0) specification 6.1.2.3 "USSD packing of 7 bit characters", in 160 octets, it's possible to pack (160 * 8) / 7 = 182.8, that is 182 characters. The remaining 6 bits are set to zero. This change defines both mentioned values: - GSM0480_USSD_OCTET_STRING_LEN 160 - GSM0480_USSD_7BIT_STRING_LEN 182 keeping the old MAX_LEN_USSD_STRING 'as is' due to compatibility reasons. Now the new value is used for ss_request structure, while old one is still used for deprecated ussd_request structure. Change-Id: I6dead74f9ecea079752ff2400cdaf7c30187784e
2018-01-15libosmocodec: implement ECU (Error Concealment Unit) for FRPhilipp Maier1-0/+15

This change implements a functionality to craft a replacement frame from the last known good frame. Currently, only FR is supported, support for other codecs may be added latter.

2018-01-08Add function to properly encode RAIMax2-0/+2
Add gsm48_encode_ra() which takes appropriate struct as [out] parameter instead of generic buffer. Using uint8_t buffer instead of proper struct type prooved to be error-prone - see Coverity CID57877, CID57876. Old gsm48_construct_ra() is made into tiny wrapper around new function. The test output is adjusted because of the change in function return value which was constant and hence ignored anyway. Related: OS#1640 Change-Id: I31f9605277f4945f207c2c44ff82e62399f8db74

2017-12-18add ctrl_cmd_parse2() to return parsing errorsNeels Hofmeyr1-0/+1
If a control command fails to parse, we so far discard specific error messages and instead send just "Command parser error". In ctrl_cmd_parse() we actually compose detailed error replies, but in the end simply talloc_free() them and return NULL. A first step to report these errors to the ctrl command issuer is to not return NULL and instead return the cmd with type = CTRL_TYPE_ERROR. Add ctrl_cmd_parse2() to return such instead of NULL. To stay API compatible, provide ctrl_cmd_parse2() to return a cmd on errors. ctrl_cmd_parse() retains identical behavior but becomes just a simple wrapper around ctrl_cmd_parse2() which discards the cmd on error. No need really to deprecate ctrl_cmd_parse() yet; especially as long as compiler warnings might break jenkins builds. Change-Id: I5047c9f977d70b03eea77cbcfd2b96d43ea46880
2017-12-18ctrl: prep test: separate new ctrl_handle_msg() from handle_control_read()Neels Hofmeyr1-0/+2

2017-12-18utils: add osmo_escape_str()Neels Hofmeyr1-0/+3
To report invalid characters in identifiers, it is desirable to escape any weird characters. Otherwise we might print stray newlines or control characters in the log output. ctrl_test.c already uses a print_escaped() function, which will be replaced by osmo_escape_str() in a subsequent patch. control_cmd.c will use osmo_escape_str() to log invalid identifiers.

2017-12-18add osmo_auth_c3() (separate from gsm_milenage())Neels Hofmeyr1-0/+2
To send a Ciphering Mode Command, we may need to derive a Kc from UMTS AKA tokens. gsm_milenage() derives Kc from 3G tokens, but also derives an SRES. For SRES, it requires an OPC, which may need to be derived from OP first. All we need is a Kc, so we could feed a zero OPC ... but to simplify the function call for cases where just a Kc is required, separate the c3 function out from gsm_milenage(), as osmo_auth_c3(). Obviously call osmo_auth_c3() from gsm_milenage() (meaning that osmo-hlr's 55.205 derived auc tests still cover exactly that implementation).

2017-11-20tlv_put: guard against NULL val and 0 lenNeels Hofmeyr1-2/+13
For example encode_auth_info() from gsup.c calls msgb_tlv_put(msg, iei, 0, NULL) to put a tag and len with content data following later. However, this would cause a memcpy() from a NULL pointer, in tlv_put(). Allow passing NULL and len = 0 for cases like the above: If val is NULL, use memset(0) instead of memcpy(). If len is zero, do not copy nor memset anything. Hence make tlv_put() behave in a well-defined and valid way for any and all input args; no negative fallout is possible from this patch. Add proper API doc comment. Fixes a sanitizer build failure in gsup_test: ../../../../src/libosmocore/include/osmocom/gsm/tlv.h:99:2: runtime error: null pointer passed as argument 2, which is declared to never be null Helps fix sanitizer build on debian 9.
