* Doxygen: fix documentation of rate_ctr_for_each_counter()Vadim Yanitskiy2019-03-271-4/+0
| | | | | | | | | | Doxygen was confused by duplicated documentation for both definition and declaration of rate_ctr_for_each_counter(). Moreover, both variants contained some mistakes. Let's avoid this duplication and keep the only (corrected) one. Change-Id: Icca2d4a95bd5f96ae85a86909ec90fb8677cacf3

* core/msgb.h: drop meaningless parameter of msgb_eq_* helpersVadim Yanitskiy2019-03-271-5/+5
| | | | | | | | | | | | | | | | | | | Thanks to the following Doxygen warning: msgb.h:XXX: warning: The following parameters of msgb_eq_l2(msg1, msgb2, len) are not documented: parameter 'msgb2' parameter 'len' it was discovered that parameter 'len' is not required at all. It basically doesn't make any sense to pass any length value, because it can be calculated using msgb_length(). Let's drop this parameter. Given that this part of the API was broken so far (see I1079d629abdb8770eef6be7341e586a933cd9cca), it should be more or less safe to do this. Change-Id: Icd9b72eb6bfa9628ff1ed2f948b57058551a4328
* core/msgb.h: fix dead msgb2 reference in msgb_eq_* helpersVadim Yanitskiy2019-03-271-5/+5
| | | | | | | | | | | | | | | | | | | | | | Neither Doxygen documentation of the msgb data comparison helpers, nor their actual definitions does refer msgb2. Instead, 'msg2' is referenced in both cases. This was discovered while investigating the following Doxygen warnings: msgb.h:XXX: warning: argument 'msg2' of command @param is not found in the argument list of msgb_eq(msg1, msgb2, len) msgb.h:XXX: warning: The following parameters of msgb_eq_l2(msg1, msgb2, len) are not documented: parameter 'msgb2' parameter 'len' Due to this bug it was impossible to use the affected macros, because 'msg2' was not listed in their parameters. Having the unit test coverage would spot this bug at the beginning! Change-Id: I1079d629abdb8770eef6be7341e586a933cd9cca

* select: Rename BSC_FD_* constants to OSMO_FD_*Harald Welte2019-03-211-5/+10
| | | | | | | | | | | | The naming of these constants dates back to when the code was private within OpenBSC. Everything else was renamed (bsc_fd -> osmo_fd) at the time, but somehow the BSC_FD_* defines have been missed at the time. Keep compatibility #defines around, but allow us to migrate the applications to a less confusing naming meanwhile. Change-Id: Ifae33ed61a7cf0ae54ad487399e7dd2489986436

* fsm: add osmo_fsm_inst_state_chg_keep_or_start_timer()Neels Hofmeyr2019-03-071-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | During FSM design for osmo-msc, I noticed that the current behavior that keep_timer=true doesn't guarantee a running timer can make FSM design a bit complex, especially when using osmo_tdef for timeout definitions. A desirable keep_timer=true behavior is one that keeps the previous timer running, but starts a timer if no timer is running yet. The simplest example is: a given state repeatedly transitions back to itself, but wants to set a timeout only on first entering, avoiding to restart the timeout on re-entering. Another example is a repeated transition between two or more states, where the first time we enter this group a timeout should start, but it should not restart from scratch on every transition. When using osmo_tdef timeout definitions for this, so far separate meaningless states have to be introduced that merely set a fixed timeout. To simplify, add osmo_fsm_inst_state_chg_keep_or_start_timer(), and use this in osmo_tdef_fsm_inst_state_chg() when both keep_timer == true *and* T != 0. In tdef_test.ok, the changes show that on first entering state L, the previous T=1 is now kept with a large remaining timeout. When entering state L from O, where no timer was running, this time L's T123 is started. Change-Id: Id647511a4b18e0c4de0e66fb1f35dc9adb9177db
* represent negative T-timers as Osmocom-specific X-timersNeels Hofmeyr2019-03-062-3/+11
| | | | | | | | | | | | | | | | | | | | fi->T values are int, i.e. can be negative. Do not log them as unsigned, but define a distinct timer class "Xnnnn" for negative T values: i.e. for T == -1, print "Timeout of X1" instead of "Timeout of T4294967295". The negative T timer number space is useful to distinguish freely invented timers from proper 3GPP defined T numbers. So far I was using numbers like T993210 or T9999 for invented T, but X1, X2 etc. is a better solution. This way we can make sure to not accidentally define an invented timer number that actually collides with a proper 3GPP specified timer number that the author was not aware of at the time of writing. Add OSMO_T_FMT and OSMO_T_FMT_ARGS() macros as standardized timer number print format. Use that in fsm.c, tdef_vty.c, and adjust vty tests accordingly. Mention the two timer classes in various API docs and VTY online-docs. Change-Id: I3a59457623da9309fbbda235fe18fadd1636bff6
* log: fsm: allow logging the timeout on state changeNeels Hofmeyr2019-02-261-0/+1
| | | | | | | | | | | | | | | | Add a flag that adds timeout info to osmo_fsm_inst state change logging. To not affect unit testing, make this an opt-in feature that is disabled by default -- mostly because osmo_fsm_inst_state_chg_keep_timer() will produce non-deterministic logging depending on timing (logs remaining time). Unit tests that don't verify log output and those that use fake time may also enable this feature. Do so in fsm_test.c. The idea is that in due course we will add osmo_fsm_log_timeouts(true) calls to all of our production applications' main() initialization. Change-Id: I089b81021a1a4ada1205261470da032b82d57872

* add osmo_tdef API, originally adopted from osmo-bsc T_defNeels Hofmeyr2019-02-041-0/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move T_def from osmo-bsc to libosmocore as osmo_tdef. Adjust naming to be more consistent. Upgrade to first class API: - add timer grouping - add generic vty support - add mising API doc - add C test - add VTY transcript tests, also as examples for using the API From osmo_fsm_inst_state_chg() API doc, cross reference to osmo_tdef API. The root reason for moving to libosmocore is that I want to use the mgw_endpoint_fsm in osmo-msc for inter-MSC handover, and hence want to move the FSM to libosmo-mgcp-client. This FSM uses the T_def from osmo-bsc. Though the mgw_endpoint_fsm's use of T_def is minimal, I intend to use the osmo_tdef API in osmo-msc (and probably elsewhere) as well. libosmocore is the most sensible place for this. osmo_tdef provides: - a list of Tnnnn (GSM) timers with description, unit and default value. - vty UI to allow users to configure non-default timeouts. - API to tie T timers to osmo_fsm states and set them on state transitions. - a few standard units (minute, second, millisecond) as well as a custom unit (which relies on the timer's human readable description to indicate the meaning of the value). - conversion for standard units: for example, some GSM timers are defined in minutes, while our FSM definitions need timeouts in seconds. Conversion is for convenience only and can be easily avoided via the custom unit. By keeping separate osmo_tdef arrays, several groups of timers can be kept separately. The VTY tests in tests/tdef/ showcase different schemes: - tests/vty/tdef_vty_test_config_root.c: Keep several timer definitions in separately named groups: showcase the osmo_tdef_vty_groups*() API. Each timer group exists exactly once. - tests/vty/tdef_vty_test_config_subnode.c: Keep a single list of timers without separate grouping. Put this list on a specific subnode below the CONFIG_NODE. There could be several separate subnodes with timers like this, i.e. continuing from this example, sets timers could be separated by placing timers in specific config subnodes instead of using the global group name. - tests/vty/tdef_vty_test_dynamic.c: Dynamically allocate timer definitions per each new created object. Thus there can be an arbitrary number of independent timer definitions, one per allocated object. T_def was introduced during the recent osmo-bsc refactoring for inter-BSC handover, and has proven useful: - without osmo_tdef, each invocation of osmo_fsm_inst_state_chg() needs to be programmed with the right timeout value, for all code paths that invoke this state change. It is a likely source of errors to get one of them wrong. By defining a T timer exactly for an FSM state, the caller can merely invoke the state change and trust on the original state definition to apply the correct timeout. - it is helpful to have a standardized config file UI to provide user configurable timeouts, instead of inventing new VTY commands for each separate application of T timer numbers.

* add osmo_hexdump_buf() and testNeels Hofmeyr2019-01-281-0/+3
| | | | | | | | | | | | | | | | | | Add osmo_hexdump_buf() as an all-purpose hexdump function, which all other osmo_hexdump_*() implementations now call. It absorbs the static _osmo_hexdump(). Add tests for osmo_hexdump_buf(). Rationale: recently during patch review, a situation came up where two hexdumps in a single printf would have been useful. Now I've faced a similar situation again, in ongoing development. So I decided it is time to provide this API. The traditional osmo_hexdump() API returns a non-const char*, which should probably have been a const instead. Particularly this new function may return a string constant "" if the buf is NULL or empty, so return const char*. That is why the older implementations calling osmo_hexdump_buf() separately return the buffer instead of the const return value directly. Change-Id: I590595567b218b24e53c9eb1fd8736c0324d371d
* Rename msgb_wrap_with_TL()Max2019-01-211-1/+1
| | | | | | | | | | | | | | | This resolves an issue introduced in 84fb5bb6a09a6a358f98c654c84c3b99a0f24eef when msgb_wrap_with_TL() was introduced as an inline function with *exactly the same name* as in osmo-msc.git and openbsc.git. We *NEVER* do something like this. Functions moved from applications to library *MUST* always be renamed. This has been the case for almost a decade now. With this subsequent change we make sure the libosmocore function has a different name and doesn't clash. After this commit, old openbsc.git and osmo-bsc.git should again build fine.

* socket: add define for socket name lengthPhilipp Maier2019-01-171-0/+2
| | | | | | | | | | | The function osmo_sock_get_name_buf() can be used to write a string representation to a user provided memory. Unfortunately the proper length for the user provided memory is not obvious. To make using osmo_sock_get_name_buf() more practical, add a define constant that defines the length of the required memory. Also use this define in socket.c.

* add LOGPFSMSL(), LOGPFSMSLSRC()Neels Hofmeyr2019-01-031-6/+30
| | | | | | | | | | | | | | | | | | Using an FSM instace's logging context is very useful. Sometimes it makes sense to log something on a different logging category than the FSM definition's default category. For example, an MSC conn has aspects concerning MM, CC, RR, MGCP, ..., and currently all of those log on DMM. This came up in I358cfbaf0f44f25148e8b9bafcb9257b1952b35a, where I want to log an MGCP event using a ran_conn context, and used the conn->fi->id. That of course omits context like the current conn FSM state... I remember at least one other place where I recently added logging using some fi->id as context, so it might turn out useful in various places. Change-Id: I11b182a03f5ecb6df7cd8f260757d3626c8e945d

* add to osmo_sock_get_name*() APINeels Hofmeyr2018-12-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically, I am applying code review that I would have given had I not been on vacation when the last osmo_sock_get_name* stuff was merged. osmo_sock_get_name2() is so far a static internal function. However, it is nothing like osmo_sock_get_name(), so instead rename it to osmo_sock_get_ip_and_port(). Also make it public API, no need to hide it. I'm adding an "and" in the name to hopefully clarify: "ip_port" vs. "ip_and_port" -- there already are _get_X_ip_port() functions that only return the port string, despite "ip" in the name. Add new public osmo_sock_get_name2(), which is like osmo_sock_get_name(), except it uses a static string instead of talloc, and omits the braces. This is most convenient for log statement formats, avoiding dyn allocations. Add new osmo_sock_get_name_buf(), which is like osmo_sock_get_name2() but writes to a caller provided char buffer. Use osmo_sock_get_name_buf() in the implementation of osmo_sock_get_name(), but use another (non-static) local string buffer, because adding braces is too complex without talloc_snprintf(). Rationale: I want to improve the logging of socket errors, e.g. change DLMGCP ERROR Failed to read: 111/Connection refused (mgcp_client.c:720) to DLMGCP ERROR Failed to read: r=10.0.99.2:2427<->l=10.0.99.2:2728: 111='Connection refused' (mgcp_client.c:721) but it is just not handy to compose logging with the current API: - osmo_sock_get_name() requires a talloc_free(). - all the others require output buffers. - the only way to conveniently compose a logging string and, - notably, the only trivial way to skip the string composition if the logging level is currently muted, is to have a function that returns a static string: the new osmo_sock_get_name2(). - (I think the osmo_sock_get_{local,remote}_* convenience wrappers should never have been added, because they encourage the caller to invoke the same code twice, for IP addr and port, and throw away one half each time.)

* add osmo_bcd2str()Neels Hofmeyr2018-12-101-0/+2
| | | | | | | | | | | | | | | | | | Add a standalone bcd-to-string conversion function with generic parameters. Add a regression test in utils_test.c. So far there is no single universal implementation that converts a BCD to a string. I could only find gsm48_mi_to_string(), which also interprets surrounding bytes, MI type and TMSI as non-BCD value. The idea is to use this function from gsm48_mi_to_string() and similar implementations in subsequent commits. Root cause: in osmo-msc, I want to have an alternative MI-to-string function for composing an FSM name, which needs the BCD part of gsm48_mi_to_string() but not the TMSI part.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
