* fsm: add flag to ensure osmo_fsm_inst_term() happens only onceNeels Hofmeyr2019-04-111-38/+340
| | | | | | | | | | | To prevent re-entering osmo_fsm_inst_term() twice for the same osmo_fsm_inst, add flag osmo_fsm_inst.proc.terminating. osmo_fsm_inst_term() sets this to true, or exits if it already is true. Update fsm_dealloc_test.err for illustration. It is not relevant for unit testing yet, just showing the difference. Change-Id: I0c02d76a86f90c49e0eae2f85db64704c96a7674
* add fsm_dealloc_test.cNeels Hofmeyr2019-04-113-1/+606
| | | | | | | | | | | | | Despite efforts to properly handle "GONE" events and entering a ST_DESTROYING only once, so far this test runs straight into a heap use-after-free. With current fsm.c, it is hard to resolve the situation with the objects named "other" also causing deallocations besides the FSM instance parent/child relations. For illustration, add an "expected" test output file fsm_dealloc_test.err, making this pass will follow in a subsequent patch. Change-Id: If801907c541bca9f524c9e5fd22ac280ca16979a
* add osmo_use_count APINeels Hofmeyr2019-04-085-0/+522
| | | | | | | | | | | | | | | | | | | | | | | | | Provide a common implementation of use counting that supports naming each user as well as counting more than just one use per user, depending on the rules the caller implies. In osmo-msc, we were originally using a simple int counter to see whether a connection is still in use or should be discarded. For clarity, we later added names to each user in the form of a bitmask of flags, to figure out exactly which users are still active: for logging and to debug double get / double put bugs. This however is still not adequate, since there may be more than one CM Service Request pending. Also, it is a specialized implementation that is not re-usable. With this generalized implementation, we can: - fix the problem of inadequate counting of multiple concurrent CM Service Requests (more than one use count per user category), - directly use arbitrary names for uses like __func__ or "foo" (no need to define enums and value_string[]s), - re-use the same code for e.g. vlr_subscr and get fairly detailed VLR susbscriber usage logging for free.

* add osmo_sockaddr_str APINeels Hofmeyr2019-04-084-0/+538
| | | | | | | | | | | | | | | | | | | | | | | | For handling RTP IP addresses and ports, osmo-mgw, osmo-bsc and osmo-msc so far have their own separate shims and code duplication around inet_ntoa(), htons(), sockaddr conversions etc. Unify and standardize with this common API. In the MGW endpoint FSM that was introduced in osmo-bsc and which I would like to re-use for osmo-msc (upcoming patch moving that to osmo-mgw), it has turned out that using char* IP address and uint16_t port number types are a convenient common denominator for logging, MGCP message composition and GSM48. Ongoing osmo-msc work also uses this for MNCC. This is of course potentially useful for any other IP+port combinations besides RTP stream handling. Needless to say that most current implementations will probably stay with their current own conversion code for a long time; for current osmo-{bsc,msc,mgw} work (MGW endpoint FSM) though, I would like to move to this API here.

* osmo_escape_str_buf: Always copy, don't return input string pointerHarald Welte2019-03-292-11/+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

* gsm0808_utils: fix gsm48 multirate to S-bit converterPhilipp Maier2019-03-112-19/+68
| | | | | | | | | | | | The function gsm0808_sc_cfg_from_gsm48_mr_cfg() is used to convert a gsm48 multirate struct into a set of S-bits (S0 to S15). However, the conversion function currently does not take into account that bit S1 actually stands for four rates at once (Config-NB-Code = 1). Lets make sure that S1 is only set when the multirate configuration permits all four required rates. Change-Id: I6ad531d4e70c2252e32e2bbaca8e14a7ec6d9840 Related: SYS#4470
* gsm0808_utils: fix gsm48 multirate configuration generatorPhilipp Maier2019-03-112-35/+225
| | | | | | | | | | | | | | | | | 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. Lets fix this. - Fix wrong interpretation of the bitpatterns - 5,15K is invalid and must never be selected - Make sure that no more than 4 rates are selected in the active set - Extend unit-test Change-Id: I6fd7f4073b84093742c322752f2fd878d1071e15 Related: SYS#4470
* add gsm0808_cell_id_from_cgi(), gsm0808_cell_id_to_cgi()Neels Hofmeyr2019-03-082-8/+169
| | | | | | | | | | | | | | | | 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 Hofmeyr2019-03-072-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* fix tdef_test.c: do call the function-to-test in all casesNeels Hofmeyr2019-03-063-19/+19
| | | | | | | | | | | | Always call osmo_tdef_fsm_inst_state_chg(), also when no timeout is defined. When there is no timeout defined for a state, tdef_test.c tries to be smart and print different output. In that mess, I missed the fact that osmo_tdef_fsm_inst_state_chg() isn't always called as it should. In the same mess, the resulting state was never printed until the preceding patch, which helped to hide this bug. Change-Id: I1d953d99854422bff8eb32f051e9c6147bc836b6
* tdef_test: tweak output to prepare for a fixNeels Hofmeyr2019-03-063-21/+24
| | | | | | | | | | | | | | - Always print the state after a state transition. This shows that actually state transitions are missing for states that have no timer defined. This is a bug in tdef_test.c, to be fixed subsequently. - Instead of total time passed since start, print the individual fake time intervals. Omit initial useless zero fake time advance. - Add two more state transitions, back out from and into a state that has no timeout set. Change-Id: Icb31af96d37741e256ff07868f3d4f5c48cdda74
* represent negative T-timers as Osmocom-specific X-timersNeels Hofmeyr2019-03-062-30/+60
| | | | | | | | | | | | | | | | | | | | 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 Hofmeyr2019-02-262-10/+13
| | | | | | | | | | | | | | | | 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 Hofmeyr2019-02-0410-0/+2095
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* vty: enable optional-multi-choice syntax: [(one|two)]Neels Hofmeyr2019-02-042-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | Since very recently we sensibly handle commands like cmd ([one]|[two]|[three]) as optional multi-choice arguments. In addition, support the more obvious syntax of cmd [(one|two|three)] Internally, the tokens are mangled to [one] [two] and [three], which is how the rest of the code detects optional args, and makes sense in terms of UI: > cmd ? [one] [two] [three] (i.e. optional arguments are always shown in braces in '?' listings) Before this patch, commands defined with a syntax like [(one|two)], would lead to an assertion (shows as "multiple") during program startup.

The VTY detects optional arguments by square braces. > cmd ? [optional-arg] > cmd optional-arg ok > cmd ok However, within multi-choice args, these braces were so far not treated as optional: > list cmd2 ([one]|[two]|[three]) > cmd2 % Command incomplete In preparation for I952b3c00f97e2447f2308b0ec6f5f1714692b5b2 which will enable the more obvious syntax of cmd [(one|two)] for reasons of internal implementation, first support a syntax of cmd ([one]|[two]) The internal vty implementation always needs square braces around each option. There is currently no good way to prevent developers from defining braces inside multi-arguments, so it is easiest to allow and handle them: > list cmd2 ([one]|[two]|[three]) > cmd2 ok The VTY doesn't guard against a mix like cmd (one|[two]) With this patch, a multi-choice command is treated as optional iff the first element is in square brackets. The remaining elements' square brackets have no effect besides confusing the user. This is not explicitly checked against. In general, I would prefer to check all of these details, but the current VTY code with its endless code duplication and obscure string mangling just doesn't provide that luxury. There are numerous worse errors hidden in there. Change-Id: I9a8474bd89ddc2155c58bfca7bd038d586aaa60a

* osmo_fsm_inst_state_chg(): set T also for zero timeoutNeels Hofmeyr2019-01-293-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, if timeout_secs == 0 was passed to osmo_fsm_inst_state_chg(), the previous T value remained set in the osmo_fsm_inst->T. For example: osmo_fsm_inst_state_chg(fi, ST_X, 23, 42); // timer == 23 seconds; fi->T == 42 osmo_fsm_inst_state_chg(fi, ST_Y, 0, 0); // no timer; fi->T == 42! Instead, always set to the T value passed to osmo_fsm_inst_state_chg(). Adjust osmo_fsm_inst_state_chg() API doc; need to rephrase to accurately describe the otherwise unchanged behaviour independently from T. Verify in fsm_test.c. Rationale: it is confusing to have a T number remaining from some past state, especially since the user explicitly passed a T number to osmo_fsm_inst_state_chg(). (Usually we are passing timeout_secs=0, T=0). I first thought this behavior was introduced with osmo_fsm_inst_state_chg_keep_timer(), but in fact osmo_fsm_inst_state_chg() behaved this way from the start. This shows up in the C test for the upcoming tdef API, where the test result printout was showing some past T value sticking around after FSM state transitions. After this patch, there will be no such confusion. Change-Id: I65c7c262674a1bc5f37faeca6aa0320ab0174f3c

* add osmo_hexdump_buf() and testNeels Hofmeyr2019-01-282-0/+122
| | | | | | | | | | | | | | | | | | 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

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.

* gsm23003: add osmo_imei_str_valid()Oliver Smith2019-01-142-0/+54
| | | | | | | | | | | Verify 14 digit and 15 digit IMEI strings. OsmoHLR will use the 14 digit version to check IMEIs before writing them to the DB. Place the Luhn checksum code in a dedicated osmo_luhn() function, so it can be used elsewhere. Related: OS#2541 Change-Id: Id2d2a3a93b033bafc74c62e15297034bf4aafe61
* port arfcn range encode support from osmo-bscStefan Sperling2019-01-122-0/+402
| | | | | | | | | | | | | | As part of fixing issue OS#3075, we want to migrate support for encoding system information from osmo-bsc to libosmocore. This change ports one of the prerequisites for doing so: osmo-bsc code for range-encoding ARFCNs, including tests. An osmo_gsm48_ prefix has been prepended to public symbols in order to avoid clashes with existing symbols in osmo-bsc code. Change-Id: Ia220764fba451be5e975ae7c5eefb1a25ac2bf2c Related: OS#3075
* add osmo_mi_name(), for MI-to-string like "IMSI-123456"Neels Hofmeyr2019-01-082-0/+44
| | | | | | | | We have gsm48_mi_to_string() and osmo_bcd2str(), but still lack a function that conveniently prints both MI type and value in one function call. Related: http://people.osmocom.org/neels/mi_mi_mi.jpg Change-Id: I7798c3ef983c2e333b2b9cbffef6f366f370bd81
* tests/gsup_test.c: drop session IEs from MO-ForwardSM ErrorVadim Yanitskiy2019-01-052-10/+4
| | | | | | | | Both session state and session ID IEs were left from the initial version of Ibe325c64ae2d6c626b232533bb4cbc65fc2b5d71. There is no need to use them (as we use SM-RP-MR), so let's clean up. Change-Id: I0d910b87f15ffbc0aeeca9cb4fcbef32bdf3ef88
