2019-04-09gsm_03_40.h: define max SM-TP-UDL (User-Data-Length) valuesVadim Yanitskiy1-0/+5
As per 3GPP TS 03.40, section 9.2.3.16 "TP-User-Data-Length (TP-UDL)" field may contain up to 140 octets (or 140 * 8 / 7 = 160 septets). Change-Id: I54f88d2908ac47228813fb8c049f4264e5145241
2019-04-08add osmo_use_count APINeels Hofmeyr9-0/+1031
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.

2019-04-08add osmo_sockaddr_str APINeels Hofmeyr9-2/+1008
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.

2019-04-08gsm_utils: fix use buf_len instead of sizeof in osmo_dump_gsmtime_bufPhilipp Maier1-1/+1
The function osmo_dump_gsmtime_buf gets a pointer *buf and a parameter buf_len. The pointer *buf is a string buffer and the function places an \0 at the end of the buffer before it exists. However it uses sizeof(buf) as part of the index calculation, which is incorrect. Lets correct this by using buf_len instead. Change-Id: Id24263aa7c9a53544f1639b6ceb09ce5615d5114
2019-04-03Add _buf() functions to bypass static string buffersHarald Welte25-118/+362
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.

2019-03-29osmo_escape_str_buf: Always copy, don't return input string pointerHarald Welte4-31/+10
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

2019-03-28ipa: Document ipa_ccm_idtag_parse_off and fix ipa_ccm_idtag_parsePau Espin Pedrol1-1/+11
ipa_ccm_idtag_parse_off is broken, and can only be used with len_offset=1 on ID Request messages, otherwise won't work correctly. Modify ipa_ccm_idtag_parse to at least parse those correctly, and document the limitations. Those two functions are already deprecated and only used in openbsc by 3 callers: * ipa_ccm_idtag_parse in ussd_read_cb(): Broken, that function can only work for Requests and it's used to parse a Response. * ipa_ccm_idtag_parse_off in forward_sccp_to_msc (NAT): Broken, it can only be used to parse Requests and it's used to parse a Response. Furthermore, len_offset=2 is passed which makes no sense and most probably it fails always, or can even make the program crash. * ipa_ccm_idtag_parse_off in (answer_challenge): This one is fine and could actually be replaced with ipa_ccm_id_get_parse after this commit is merged.

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

Neither Doxygen documentation of the msgb data comparison helpers, nor their actual definitions does refer msgb2. Instead, 'msg2' is referenced in both cases.

2019-03-16gprs_ns: Don't use initial IP/port for anything but SNSHarald Welte1-2/+55
Section 6.2.1 of 3GPP TS 48.016 states: > A pre-configured endpoint shall not be used for NSE data or signalling > traffic (with the exception of Size and Configuration procedures) unless > it is configured by the SGSN using the auto-configuration procedures. However, in the current SNS implementation, the initial IP/Port over which we perform the SNS-SIZE + SNS-CONFIG are treated as one of the normal NS-VCs. Specifically, we also perform the NS-ALIVE procedure on it, which is clearly wrong. Let's explicitly create the "initial" NS-VC with data and signalling weight of 0, and ensure we never start the alive timer or send any non-SNS PDUs on this connection as long as SNS was not used to change either of the two weights to non-zero. While at it, also safeguard against processing any incoming non-SNS messages on such a all-zero-weight connection. Change-Id: I16a91a07e5914d123b2ea2f8413b94e7cd518628 Closes: OS#3844

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).

2019-03-08add gsm0808_cell_id_from_cgi(), gsm0808_cell_id_to_cgi()Neels Hofmeyr6-8/+270
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
2019-03-07fsm: add osmo_fsm_inst_state_chg_keep_or_start_timer()Neels Hofmeyr5-17/+76
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

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
2019-03-06tdef_test: tweak output to prepare for a fixNeels Hofmeyr3-21/+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
2019-03-06represent negative T-timers as Osmocom-specific X-timersNeels Hofmeyr7-52/+111
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
