* fsm: factor out osmo_fsm_inst_term_children() from osmo_fsm_inst_term()Neels Hofmeyr2016-12-241-0/+13
| | | | | | | | | | | | | | | | | | | | osmo_fsm_inst_term() has code for safe child removal, publish that part as osmo_fsm_inst_term_children(); also use from osmo_fsm_inst_term(). As with osmo_fsm_inst_term(), add osmo_fsm_inst_term_children() macro to pass the caller's source file and line to new _osmo_fsm_inst_term_children(). Rationale: in openbsc's VLR, I want to discard child FSMs when certain events are handled. I could keep a pointer to each one, or simply iterate all children, making the code a lot simpler in some places. (Unfortunately, the patch may be displayed subobtimally. This really only moves the children-loop to a new function, replaces it with a call to _osmo_fsm_inst_term_children(fi, OSMO_FSM_TERM_PARENT, NULL, file, line) and drops two local iterator variables. No other code changes are made, even though the diff may show large removal + addition chunks) Change-Id: I8dac1206259cbd251660f793ad023aaa1dc705a2
* fsm: move LOGPFSMSRC and LOGPFSMLSRC to .hNeels Hofmeyr2016-12-241-0/+13
| | | | | | | | | | | LOGPFSM and LOGPFSML are in the header file, put the *SRC variants also there so users of the osmo_fsm_inst API may conveniently create own functions that log the caller's source file and line. Very useful if many action functions call the same event dispatching function, like foo_fsm_done(), and one needs to know which of the callers to debug.

* utils.h: add OSMO_STRINGIFY and OSMO_VALUE_STRING macrosNeels Hofmeyr2016-12-211-0/+4
| | | | | | | | | | | | | | OSMO_STRINGIFY particularly allows putting port numbers from a #define into VTY doc strings, like: #define FOO_PORT 2342 DEFUN(..., "Foo UDP port (default: " OSMO_STRINGIFY(FOO_PORT) ")\n") OSMO_VALUE_STRING creates value_string items with the string being exactly the enum value's name. Replaces a similar macro def in fsm.c Change-Id: I857af45ae602bb9a647ba26cf8b0d1b23403b54c

* fsm: log caller's source for events and state changes, not fsm.c linesNeels Hofmeyr2016-12-142-10/+58
| | | | | | | | | | | | | | | | | | | | | | | When looking at log output, it is not interesting to see that a state transition's petty details are implemented in fsm.c. Rather log the *caller's* source file and line that caused an event, state change and cascading events. To that end, introduce LOGPSRC() absorbing the guts of LOGP(), to be able to explicitly pass the source file and line information. Prepend an underscore to the function names of osmo_fsm_inst_state_chg(), osmo_fsm_inst_dispatch() and osmo_fsm_inst_term(), and add file and line arguments to them. Provide the previous names as macros that insert the caller's __BASE_FILE__ and __LINE__ constants for the new arguments. Hence no calling code needs to be changed. In fsm.c, add LOGPFSMSRC to call LOGPSRC, and add LOGPFSMLSRC, and use them in above _osmo_fsm_inst_* functions. In addition, in _osmo_fsm_inst_term(), pass the caller's source file and line on to nested event dispatches, so showing where a cascade originated from.

* fsm: add LOGPFSML to pass explicit logging levelNeels Hofmeyr2016-12-141-2/+5
| | | | | | | | | | | | | | Provide one central LOGPFSML to print FSM information, take the FSM logging subsystem from the FSM instance but use an explicitly provided log level instead of the FSM's default level. Use to replace some, essentially, duplications of the LOGPFSM macro. In effect, the fsm_test's expected error changes, since the previous code dup for logging events used round braces to indicate the fi's state, while the central macro uses curly braces.

* import oap message parsing / encoding from openbsc.git; AGPL->GPLHarald Welte2016-12-113-1/+75

* fix: DLGSUP logging category "unusable"Neels Hofmeyr2016-12-111-1/+1
| | | | | | | | | | | | | | | | | | | All DL* categories are typically negative, but DLGSUP isn't, and it's also not in libosmocore's internal_cat array. See: 3b6fb0880c3ab1e23a3d7d738d073b00c2a794c2 This means that a program using DLGSUP has to include DLGSUP in its own logging cat array (typically not needed for DL* categories), which means for osmo-nitb that DLGSUP (11) replaces DMGCP (also 11), and DMGCP becomes unusable. Fix this: make DLGSUP -11 and include in internal_cat. In gsup_test.c, no longer add DLGSUP to the logging categories array. External follow-ups are otherwise needed only in osmo-hlr.git and some pending patches for openbsc (Id3938267fa062e1a997d3704cd678874306f86ee). Change-Id: Id974c7be158e4d60421a98110f5c807aefd31119
* Implement GSMTAP log targetHarald Welte2016-12-091-0/+14

* gsmtap: Add defintions for GSMTAP based remote loggingHarald Welte2016-12-091-0/+19
| | | | | | | | | | | Often it is useful to have log statements from the osmocom programs synchronized with protocol traces. So rather than having to open the pcap file with GSMTAP or other protocol data side-by-side with the textual log of one or more network elements, we simply pass the log lines around as GSMTAP messages, which can then be displayed in-order and interspersed with the protocol messages inside wireshark.

* cosmetic: gsup comments: write 'Generic' for the G in GSUPNeels Hofmeyr2016-12-091-1/+1
| | | | | | | | The G used to mean GPRS, but the scope is larger now. To satisfy the curious reader, give the G a name in gsup files' header comments. BTW, logging.h and gsup_test.c already mentioned "Generic" before this. Change-Id: I6ac5cf94c215e156ceff6a58da3d9e520ca942d9

* logging: Extend log_target with call-back for un-formatted log lineHarald Welte2016-12-021-1/+17
| | | | | | | | | | | Some targets might not want to receive only an opaque, pre-formatted string, but rather the unformatted arguments with metadata like sub-system/level/file/line. We solve this by introducing a log_target->output_raw() function pointer. If a target specifies this function, it takes precedence over the regular log_target->output() function.

* gsm0480: add gsm0480_create_ussd_notify() and *_release_complete()Neels Hofmeyr2016-12-011-0/+2
| | | | | | | | | | | Add two functions to create USSD messages. Moves and generalizes code from openbsc. Pending: use the new functions in openbsc.

* Introduce osmo_strlcpy() function so we can stop using strncpy()Harald Welte2016-11-261-0/+2
| | | | | | | | | | | | | | | | I'm aware of the existing criticism on stlrcpy(), but I think it is still better than what we have now: stnrcpy(), sometimes with Coverity warnings and sometimes with a manual setting of the termination byte. The implementation follows the linux kernel strlcpy() which is claimed to be BSD compatible. We could of course link against libbsd on Linux instead, but I think it's reasonably small and simple to provide our own implementation. Future versions of libosmocore could use some autoconf magic and preprocessor macros to use the system-provided strlcpy() if it exists. Change-Id: Ifdc99b0e3b8631f1e771e58acaf9efb00a9cd493

* RSL: Add defines for ericsson systinfo SI13Philipp2016-11-161-0/+4
| | | | | | | | | | | | | | Ericsson uses non standard information element tags when setting up the SI13 system information configuration. This applies to RSL_SYSTEM_INFO_13, which is normally 0x28, instead Ericsson uses RSL_ERIC_SYSTEM_INFO_13, which is set to 0x0C. Furthermore, Ericsson adds a propritary field called BCCH-Mapping, which is tagged as 0xf2 (RSL_IE_ERIC_BCCH_MAPPING) This patch addes these two information element tags in gsm_08_58.h Change-Id: Idc27352e286b9b8bbcbf0b31bdb676c3d13487a9

* msgb: add msgb_talloc_ctx_init(), deprecate msgb_set_talloc_ctx()Neels Hofmeyr2016-09-271-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far each and every main() scope creates a msgb talloc context and either passes it to msgb_set_talloc_ctx() or sets tall_msgb_ctx directly (by defining it extern first). Remove some code duplication: add one central function that creates the "msgb" talloc context for all. Most users of msgb employ a talloc_named_const(), but osmo-bts uses a talloc_pool() instead. Offer both ways by means of the pool_size argument, and for both ways make sure the context is called "msgb". Suggest that msgb users should move to this new function: deprecate msgb_set_talloc_ctx(). To be able to do so, include core/defs.h in msgb.h. There's a tradeoff between hiding the msgb talloc context behind API that tries to guess all use cases versus avoiding code dup. This patch opts against code dup and boldly assumes that all future use is covered. Also, the new function suggests to not access tall_msgb_ctx directly, which can be considered a style improvement. It seems that not all main scopes that use msgb actually initialize the msgb ctx. As a fallback for these, explicitly initialize tall_msgb_ctx to NULL.
