* Add _buf() functions to bypass static string buffersHarald Welte2019-04-0312-1/+25
| | | | | | | | | | | | | | | We have a number of static buffers in use in libosmo*. This means the related functions are not usable in a thread-safe way. While we so far don't have many multi-threaded programs in the osmocom universe, the static buffers also prevent us from calling the same e.g. string-ify function twice within a single printf() call. Let's make sure there's an alternative function in all those cases, where the user can pass in a caller-allocated buffer + size, and make the 'classic' function with the static buffer a wrapper around that _buf() variant.

* osmo_escape_str_buf: Always copy, don't return input string pointerHarald Welte2019-03-291-1/+1
| | | | | | | | | | | osmo_escape_str_buf() used to have the somewhat odd semantics that if no escaping was needed, it would return the original pointer without making any copy to the output buffer. While this seems like an elegant optimization, it is a very strange behavior and it works differently than all of our other *_buf() functions. Let's unify the API and turn osmo_escape_str_buf() into a strlcpy() if no escaping is needed. Change-Id: I3a02bdb27008a73101c2db41ac04248960ed4064
* Doxygen: fix documentation of rate_ctr_for_each_counter()Vadim Yanitskiy2019-03-271-4/+0

* 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.

* gsm0808_utils: fix gsm48 multirate configuration generatorPhilipp Maier2019-03-112-1/+15
| | | | | | | | | | | | | | | | | The function gsm0808_sc_cfg_from_gsm48_mr_cfg() takes an S15 to S0 bitmask and converts that bitmask into an AMR multirate configuration struct. Unfortunately the current implementation implements 3GPP TS 28.062, Table 7.11.3.1.3-2 wrongly in some aspects.

* add gsm0808_cell_id_from_cgi(), gsm0808_cell_id_to_cgi()Neels Hofmeyr2019-03-082-0/+12
| | | | | | | | | | | | | | | | CGI to Cell ID: for example, for Paging, osmo-msc has a CGI for a subscriber and needs to send out a Cell Identifier IE. Makes sense to add this conversion here. Cell ID to CGI: for a Layer 3 Complete, a subscriber sends the current cell in the form of a Cell Identifier, which we store as a CGI, if necessary enriched with the local PLMN. Add enum with bitmask values to identify parts of a CGI, for the return value of gsm0808_cell_id_to_cgi(). Can't use enum CELL_IDENT for that, because it doesn't have a value for just a PLMN (and is not a bitmask). Change-Id: Ib9af67b100c4583342a2103669732dab2e577b04
* 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 Hofmeyr2019-03-063-4/+14
| | | | | | | | | | | | | | | | | | | | 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
* NS: Add support for GPRS NS IP Sub-Network-Service (SNS)Harald Welte2019-02-262-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The NS implementation part of the Gb implementation libosmogb so far implemented a rather classic dialect of Gb, with lots of heritage to FR (Frame Relay) transports. At least since Release 6 of the NS specification, there's an IP Sub-Network Service (SNS), which * permits for dynamic configuration of IP endpoints and their NS-VCs * abandons the concept of a NSVCI on IP transport * forbids the use of RESET/BLOCK/UNBLOCK procedures on IP transport This commit introduces BSS-side IP-SNS support to libosmogb in a minimally invasive way. It adds a corresponding SNS FSM to each NS instance, and implements the new SIZE/CONFIG/ADD/DELETE/CHANGE_WEIGHT procedures very closely aligned with the spec. In order to use the SNS flavor (rather than the classic one), a BSS implementation should use gprs_ns_nsip_connect_sns() instead of the existing gprs_ns_nsip_connect(). This implementation comes with a set of TTCN-3 tests in PCU_Tests_RAW_SNS.ttcn, see Change-ID I0fe3d4579960bab0494c294ec7ab8032feed4fb2 of osmo-ttcn3-hacks.git Closes: OS#3372 Closes: OS#3617 Change-Id: I84786c3b43a8ae34ef3b3ba84b33c90042d234ea

* enlarge gsm0808 msgb headroomNeels Hofmeyr2019-02-261-2/+2
| | | | | | | | | | | | | | | | It should be large enough to prepend a struct osmo_scu_prim to pass down an SCCP stack (see libosmo-sccp). 264 should suffice, but pick the next larger power-of-two instead. In osmo-msc, I would like to prepend an osmo_prim to the msgb created by gsm0808 API, but turns out the headroom is too small: msgb(0x61700001b660): Not enough headroom msgb_push (126 < 264) Instead of always copying a msgb that has just that instant been created, it makes more sense to allocate sufficient headroom in the first place.

* add osmo_tdef API, originally adopted from osmo-bsc T_defNeels Hofmeyr2019-02-043-0/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* gsm0808: add BSSMAP Cell Identifier matching APINeels Hofmeyr2019-01-282-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Add * osmo_lai_cmp() (to use in gsm0808_cell_id_u_matches()) * osmo_cgi_cmp() (to use in gsm0808_cell_id_u_matches()) * gsm0808_cell_id_u_match() (to re-use for single IDs and lists) * gsm0808_cell_ids_match() * gsm0808_cell_id_matches_list() * Unit tests in gsm0808_test.c Rationale: For inter-BSC handover, it is interesting to find matches between *differing* Cell Identity kinds. For example, if a cell as CGI 23-42-3-5, and a HO for LAC-CI 3-5 should be handled, we need to see the match. This is most interesting for osmo-msc, i.e. to direct the BSSMAP Handover Request towards the correct BSC or MSC. It is also interesting for osmo-bsc's VTY interface, to be able to manage cells' neighbors and to trigger manual handovers by various Cell Identity handles, as the user would expect them.

* constrain gsm48_generate_mid() output array boundsHarald Welte2019-01-221-0/+1
| | | | | | | | | | | The longest BCd-digit type identity is the IMEISV with 16, so there's no point in trying to parse up to 255 decimal digits, which will do nothing but to overflow the caller-provided output buffer. Let's also clearly define the required minimum size of the output buffer and add a reltead #define for it. Change-Id: Ic8488bc7f77dc9182e372741b88f0f06100dddc9
* gsm_23_003.h: add GSM23003_IMEI_NUM_DIGITS_NO_CHKOliver Smith2019-01-211-0/+3
| | | | | | | Add new define for the 14 digit IMEI without the Luhn checksum, as it is used in OsmoHLR. Change-Id: I02b54cf01a674a1911c5c897fbec02240f88b521
* 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.

* Prevent GCR encoder/decoder functions from being used directlyMax2019-01-191-2/+2
| | | | | | | | They only make sense in the context of LCLS so far - let's make sure they're not used by external projects directly instead of gsm0808_*() counterparts. Change-Id: I4ae5a3472a20492d5f76170b722e4e2274a5c433
* LCLS: make GCR into static member of osmo_lclsMax2019-01-191-1/+2
| | | | | | | | | Most of the time we'll have GCR filled anyway so it make sense to have it as static parameter instead of a pointer
