* gsm0808: add encoder for cause codes and use itPhilipp Maier2018-12-081-0/+1
| | | | | | | | | | | | | | | | At the moment the all gsm0808 cause codes are encoded directly using the tlv API directly to put a one byte TLV field. This works ok for most situations where the cause code consists of a single byte. However, gsm0808 specifies a two byte cause code model where cause codes may be extended up to two bytes. Instead of implementing the encoding over and over and again, let's rather have an encoder function we can call. - Add an encoder function that can generate single byte and extended cause codeds and makes the length decision automatically. - Use only this function to append cause codes Change-Id: I71d58fad89502a43532f60717ca022c15c73f8bb

Make osmo_sockaddr_to_str_and_uint() into wrapper around new function and make sure to check for address family before typecasting. Also use proper return type.

* gsm: Deprecate buggy gsm_arfcn2band API and introduce gsm_arfcn2band_rcPau Espin Pedrol2018-11-201-1/+2
| | | | | | | | | | | | | | | | | | | ARFCNs are values in well defined ranges. Until this patch, ARFCNs not belonging to any band were blindly assigned to DCS1800 by gsm_arfcn2band, causing unnoticed bugs and misconfigurations in osmo-bsc. Previous API gsm_arfcn2band cannot accomodate this kind of check easily, so let's deprecate it to tell people to use a new API gsm_arfcn2band_rc which performs this kind of checks and allows callers to log failures, misconfigurations, etc. At the same time, modify implementation of gsm_arfcn2band to abort if an invalid ARFCN is passed, this way users of this API can notice they are passing wrong data to it that most probably will produce unexpected results.

* logging vty: rewrite 'logging level' vty cmd generationNeels Hofmeyr2018-09-132-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Completely drop the implementations of log_vty_command_{str,description}(). These functions have been public API once, marked as deprecated since c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7 (March 2017). I considered to keep them, or reduce them to useless stubs, but it is quite silly, really. These functions are completely and utterly useless outside of libosmocore. Any program linking these deserves to fail. Re-implement vty logging level command gen, in logging_vty.c. logging.c is simply the wrong place for that. Introduce logging_internal.h to share logging definitions to logging_vty.c without publishing as API. Introduce static gen_logging_level_cmd_strs() to compose a list of category arguments with their descriptions for VTY commands. Use osmo_talloc_asprintf() instead of the previous error prone and chaotic strlen() counting method. Do not dynamically generate log level arguments, just keep static strings. We are super unlikely to ever change the log levels we have. No changes in logging_vty_test.vty: proves that there is no functional change. All of this, besides introducing basic sanity, is cosmetic preparation to be able to re-use the generic command generation code for arbitrary commands with category or level args (for deprecated and new keywords). Rationale: I want to hide 'all' and 'everything' from the VTY command documentation, by means of deprecating. I first tried to simply define a deprecated 'logging level CAT everything' command: logging level (all|rsl|rr|...) (debug|info|notice|error|fatal) logging level CAT everything # <- deprecated and hidden But unfortunately, command matching doesn't work as intended when the CAT argument reflects a valid category; I want it to invoke the deprecated function as soon as the 'everything' keyword follows, but it stays stuck to the "valid" command when the category argument matches an explicit keyword in that list, and will throw an error on the following 'everything' keyword. I.e.: logging level rsl everything % Unknown command # <-- leads to config file parse error logging level unknown_string everything % Ignoring deprecated 'everything' # <-- works only for invalid categories So I need to define 'everything' separately, again with a list of each valid category instead of a generic CAT arg.

| | | | | | | | | | | | | | | | | | | | | | | | | We already have osmo_str2lower() and osmo_str2upper(), but these lack: * proper destination buffer bounds checking, * ability to call directly as printf() argument.

Introduce osmo_str_tolower_buf(), osmo_str_toupper_buf() to provide bounds-safe conversion, also able to safely convert a buffer in-place. Introduce osmo_str_tolower(), osmo_str_toupper() that call the above _buf() equivalents using a static buffer[128] and returning the resulting string directly, convenient for direct printing. Possibly truncated but always safe. Add unit tests to utils_test.c. Replace all libosmocore uses of now deprecated osmo_str2lower(). Naming: the ctype.h API is called tolower() and toupper(), so just prepend 'osmo_str_' and don't separate 'to_lower'. Change-Id: Ib0ee1206b9f31d7ba25c31f8008119ac55440797
