* Revert "Change GSM48_PDISC_* to enum type"Harald Welte2019-05-181-20/+18
| | | | | | | This reverts commit ece1d8509d5c5af7a60ab5e1a5dddade1b181dc9 which causes build failures due to compile warnings everywhere. Change-Id: Ic131439ea206a0b0f57968ef701667da73711b51
* Change GSM48_PDISC_* to enum typeMax2019-05-171-18/+20
| | | | | | | | An enum is more clear than an int and #defines for passing around, also in case you have a switch () statement, the compiler will issue warnings for unhandled cases. Change-Id: Icbbe8786a776081d7643193f154e6270224399e6
* gsm_23_003: add GSM23003_MSISDN_{MIN,MAX}_DIGITSOliver Smith2019-05-151-0/+3
| | | | | | | | | | | Add the constant, so it can be used in create-subscriber-on-demand related patches. ITU-T Rec. E.164 6.1 states that maximum international number length should be 15. I did not find a source for a minimum length, but I've added the constant and set it to 1 for consistency (based on the existing osmo_msisdn_str_valid() function).

* gsm0808: Introduce Osmocom extensions to announce Osmux supportPau Espin Pedrol2019-05-132-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | IE GSM0808_IE_OSMO_OSMUX_SUPPORT (T, 1 byte) is sent in AoIP appended to BSSMAP RESET in order to announce the peer that its MGW supports handling Osmux streams upon call set up. IE GSM0808_IE_OSMO_OSMUX_CID (TV, T 1 byte & V 1 byte) is sent in AoIP during call set up: * MSC->BSC Assignment Request * BSC->MSC Assignemnt Complete The 1 byte value contains the local Osmux CID, aka the recvCID aka CID where the peer sending the Assign Req/Compl will look for Osmux frames on that call. Hence, the peer receiving this CID value must use it to send Osmux frames for that call. As a result, a given call leg BSC<->MSC can have one different Osmux CID per direction. For example: * MS => MGW_BSC ==CID 0==> MGW_MSC * MS <= MGW_BSC <=CID 1=== MGW_MSC This allows for setups with 256 call legs per BSC on scenarios where NAT is not a problem, where MSC can have a pool of 256 CID per MGW_BSC (or remote peer).

* gsm0808_utils: Introduce gsm0808_msgb_put_cell_id_u()Harald Welte2019-05-101-0/+1
| | | | | | | | | | | | This function is doing the bulk work of encoding a given Cell ID List item. gsm0808_enc_cell_id_list2() is modified to be a wrapper / loop around the new function. The purpose of this is to expose Cell ID List Entry encoding so that the upcoming CBSP protocol encoder can re-use this code. Related: OS#3537 Change-Id: I6cc567798e20365e6587e6b2988e834306d8c80c

* Re-introduce declaration of gsm0808_create_handover_request_ack()Harald Welte2019-05-061-0/+4
| | | | | | | | | | | | | In Change-Id Ia71542ea37d4fd2c9fb9b40357db7aeb111ec576, the old declaration of gsm0808_create_handover_request_ack() was accidentially removed from the gsm0808.h header file. The actual function itself (and the exported symbol) remained for backwards compatibility at runtime, but removing the declaration from the header file resulted in build failures across the board of all automatic tests. Let's re-introduce the old declaration. Change-Id: I9e96fa675fccca9ee9631caad7559dea3794d490
* add gsm0808_create_handover_request_ack2 to add AoIP RTP addrNeels Hofmeyr2019-05-051-3/+23
| | | | | | | | | | | | | | | | | | | osmo-bsc so far omits the AoIP Transport Layer Address from its Handover Request Acknowledge message, which breaks inter-BSC Handover for AoIP. Allow fixing that. One quirk I really don't like about this: I would prefer to directly use struct sockaddr_storage as a member of the struct gsm0808_handover_request_ack. Even though struct sockaddr_storage appears in various function signatures, the gsm0808.c actually also gets built on embedded systems that lack arpa/inet.h (for me indicated by the ARM build job on jenkins). Compiling gsm0808.c works only because the actual coding of struct sockaddr_storage is implemented in gsm0808_util.c, which (apparently) does not get built on embedded and hence, even though there are undefined references to e.g. gsm0808_enc_aoip_trasp_addr() it works.

* add vty_is_active()Neels Hofmeyr2019-05-031-0/+2
| | | | | | | | | | | | | For async callbacks it is useful to determine whether a given VTY pointer is still valid. For example, in osmo-msc, a silent call can be triggered by VTY, which causes a Paging. The paging_cb then writes to the VTY console that the silent call has succeeded. Unless the telnet vty session has already ended, in which case osmo-msc crashes; e.g. from an osmo_interact_vty.py command invocation. With this function, osmo-msc can ask whether the vty pointer passed to the paging callback is still active, and skip vty_out() if not. Change-Id: I42cf2af47283dd42c101faae0fac293c3a68d599
* add osmo_bssap_tlv_parse2() for multiple identical TNeels Hofmeyr2019-05-031-0/+3
| | | | | | | | | | | | | | | | In BSSMAP messages, at least the Cell Identifier IE can appear more than once. We have tlv_parse2() which allows decoding into an array of tlv_parsed to cleanly handle multiple occurences. Hence add osmo_bssap_tlv_parse2() which supports multiple occurences. An alternative would be to directly call tlv_parse2() with gsm0808_att_tlvdef() when multiple T occurences are needed, and I'm not really sure why osmo_bssap_tlv_parse() exists in the first place. But because it does, add a similar definition that is capable of handling multiple IEs with identical Tag discriminator. Change-Id: Ib9a2095f7498dc2cda2a57154b2dbe4621df72f8
* add gsm48_decode_bcd_number2() from osmo-mscNeels Hofmeyr2019-05-031-1/+5
| | | | | | | | | | | | gsm48_decode_bcd_number() is unable to provide proper bounds validation of input and output data, hence osmo-msc's vlr.c introduced a static decode_bcd_number_safe() a long time ago. Move to libosmocore. I need to use the same function to decode an MSISDN during inter-MSC Handover, instead of making it public in osmo-msc, rather deprecate the unsafe function and provide a safer version for all callers. Mark the old one deprecated. Change-Id: Idb6ae6e2f3bea11ad420dae14d021ac36d99e921

* GSUP: add inter-MSC handover related msgs and IEsOliver Smith2019-04-261-0/+66
| | | | | | | | | | | | | | | | | | | | Based on a draft created by Neels, which is the result of reading a MAP trace of two MSCs negotiating inter-MSC handovers, and of reading the TS 29.002, TS 29.010 and related specs: https://lists.osmocom.org/pipermail/openbsc/2019-January/012653.html I figured out that the "Handover Number" mentioned in the specifications is the same as the MSISDN IE that we already have, so we can use that instead of creating a new IE (example usage in tests/gsup/gsup_test.c). Create a new OSMO_GSUP_MSGT_E_ROUTING_ERROR message type, which the GSUP server uses to tell a client that its message could not be forwarded to the destination (see [1]). MAP has no related message.

* GSUP: add Message Class IENeels Hofmeyr2019-04-131-0/+21
| | | | | | | | | | | | | | | | | | osmo-msc and osmo-hlr have distinct subsystems handling incoming GSUP messages. So far we decide entirely by message type which code path should handle a GSUP message. Thus no GSUP message type may be re-used across subsystems. If we add a GSUP message to indicate a routing error, it would have to be a distinct message type for subscriber management, another one for SMS, another one for USSD... To allow introducing common message types, introduce a GSUP Message Class IE. In the presence of this IE, GSUP handlers can trivially direct a received message to the right code path. If it is missing, handlers can fall back to the previous switch(message_type) method. Change-Id: Ic397a9f2c4a7224e47cab944c72e75ca5592efef
* add OSMO_IMSI_BUF_SIZENeels Hofmeyr2019-04-132-1/+4
| | | | | | | | | | | | Various places in our code base figure out how many chars they need to safely store an IMSI. An IMSI can have a checksum digit, which is not reflected by GSM23003_IMSI_MAX_DIGITS. And we usually need a terminating \0. Instead of having a magic +2 repeated every so often, rather define OSMO_IMSI_BUF_SIZE to contain both checksum digit and nul char, and have the explanatory comment with it here in libosmocore.

* add identifier sanitation for setting FSM instance idsNeels Hofmeyr2019-04-122-0/+2
| | | | | | | | | | | | | | | | | | | | We often compose FSM instance IDs from context information, for example placing an MSISDN string or IP:port information in the FSM instance id, using osmo_fsm_inst_update_id_f(). This fails if any characters are contained that don't pass osmo_identifier_valid(). Hence it is the task of the caller to make sure only characters allowed in an FSM id are applied. Provide API to trivially allow this by replacing illegal chars: - osmo_identifier_sanitize_buf(), with access to the same set of illegal characters defined in utils.c, - osmo_fsm_inst_update_id_f_sanitize() implicitly replaces non-identifier chars. This makes it easy to add strings like '192.168.0.1:2342' or '+4987654321' to an FSM instance id, without adding string mangling to each place that sets an id; e.g. replacing with '-' to yield '192-168-0-1:2342' or '-4987654321'.

* add osmo_{escape,quote}_str_buf2() for standard args orderingNeels Hofmeyr2019-04-121-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be able to append an escaped or quoted string using OSMO_STRBUF_APPEND_NOLEN(), the function signature must have the buf and len as first args, like most other *_buf() functions. Add osmo_escape_str_buf2() and osmo_quote_str_buf2() to match this signature. A recent patch [1] has changed the return value of osmo_escape_str_buf() to char*, removing the const. However, the functions may return const strings, hence re-add the const. The new signatures always return the non-const buffer. To avoid code duplication, implement osmo_quote_str_buf() and osmo_escape_str_buf() by calling the new functions. I decided to allow slight changes to the behavior for current osmo_escape_str() and osmo_escape_str_buf(), because impact on callers is minimal: (1) The new implementation uses OSMO_STRBUF_*, and in consequence osmo_quote_str() no longer prints an ending double quote after truncated strings; Before, a truncated output was, sic: "this string is trunca" and now this becomes, sic: "this string is truncat I decided to not keep the old behavior because it is questionable to begin with. It looks like the string actually ended at the truncation boundary instead of the reason being not enough space in the output buffer. (2) The new osmo_escape_str_buf2() function obviously cannot pass-thru an unchanged char* if no escaping was needed. Sacrifice this tiny optimization feature to avoid code duplication: - it is an unnoticeable optimization, - the caller anyway always passes a string buffer, - the feature caused handling strings and buffers differently depending on their content (i.e. code that usually writes out strings in full length "suddenly" truncates because a non-printable character is contained, etc.) I considered adding a skip_if_unescaped flag to the osmo_quote_str_buf2() function signature, but in the end decided that the API clutter is not worth having for all the above reasons. Adjust tests to accomodate above changes. [1] 4a62eda225ab7f3c9556990c81a6fc5e19b5eec8 Ibf85f79e93244f53b2684ff6f1095c5b41203e05 Change-Id: Id748b906b0083b1f1887f2be7a53cae705a8a9ae
* tweak OSMO_STRBUF_APPEND(), add OSMO_STRBUF_APPEND_NOLEN()Neels Hofmeyr2019-04-111-7/+30
| | | | | | | | | | | | | In OSMO_STRBUF_APPEND, use local variable names that are less likely to shadow other local variables: prefix with _sb_. In OSMO_STRBUF_APPEND, add a check to add to .pos only if it is not NULL. Add OSMO_STRBUF_APPEND_NOLEN(), which works for function signatures that don't return a length. This is useful for any osmo_*_buf() string writing functions, so that these write directly to the strbuf. Change-Id: I108cadf72deb3a3bcab9a07e50572d9da1ab0359
* add osmo_str_startswith()Neels Hofmeyr2019-04-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move from a static implementation in tdef_vty.c to utils.c, I also want to use this in osmo-msc. The point is that the telnet VTY allows unambiguous partly matches of keyword args. For example, if I have a command definition of: compare (apples|oranges) then it is perfectly legal as for the vty parser to write only compare app One could expect the VTY to then pass the unambiguous match of "apples" to the parsing function, but that is not the case. Hence a VTY function implementation is faced with parsing a keyword of "app" instead of the expected "apples". This is actually a very widespread bug in our VTY implementations, which assume that exactly one full keyword will always be found. I am now writing new commands in a way that are able to manage only the starts of keywords. Arguably, strstr(a, b) == a does the same thing, but it searches the entire string unnecessarily.

* fsm: support graceful osmo_fsm_inst_term() cascadesNeels Hofmeyr2019-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add global flag osmo_fsm_term_safely() -- if set to true, enable the following behavior: Detect osmo_fsm_inst_term() occuring within osmo_fsm_inst_term(): - collect deallocations until the outermost osmo_fsm_inst_term() is done. - call osmo_fsm_inst_free() *after* dispatching the parent event. If a struct osmo_fsm_inst enters osmo_fsm_inst_term() while another is already within osmo_fsm_inst_term(), do not directly deallocate it, but talloc-reparent it to a separate talloc context, to be deallocated with the outermost FSM inst. The effect is that all osmo_fsm_inst freed within an osmo_fsm_inst_term() cascade will stay allocated until all osmo_fsm_inst_term() are complete and all of them will be deallocated at the same time. Mark the deferred deallocation state as __thread in an attempt to make cascaded deallocation handling threadsafe. Keep the enable/disable flag separate, so that it is global and not per-thread. The feature is showcased by fsm_dealloc_test.c: with this feature, all of those wild deallocation scenarios succeed. Make fsm_dealloc_test a normal regression test in testsuite.at. Rationale: It is difficult to gracefully handle deallocations of groups of FSM instances that reference each other. As soon as one child dispatching a cleanup event causes its parent to deallocate before fsm.c was ready for it, deallocation will hit a use-after-free. Before this patch, by using parent_term events and distinct "terminating" FSM states, parent/child FSMs can be taught to wait for all children to deallocate before deallocating the parent. But as soon as a non-child / non-parent FSM instance is involved, or actually any other cleanup() action that triggers parent FSMs or parent talloc contexts to become unused, it is near impossible to think of all possible deallocation events ricocheting, and to avoid running into freeing FSM instances that were still in the middle of osmo_fsm_inst_term(), or FSM instances to enter osmo_fsm_inst_term() more than once. This patch makes deallocation of "all possible" setups of complex cross referencing FSM instances easy to handle correctly, without running into use-after-free or double free situations, and, notably, without changing calling code.

Update fsm_dealloc_test.err for illustration. It is not relevant for unit testing yet, just showing the difference. Change-Id: I0c02d76a86f90c49e0eae2f85db64704c96a7674
* Add _c versions of functions that otherwise return static buffersHarald Welte2019-04-1013-0/+55
| | | | | | | | | | | | | | We have a habit of returning static buffers from some functions, particularly when generating some kind of string values. This is convenient in terms of memory management, but it comes at the expense of not being thread-safe, and not allowing for two calls of the related function within one printf() statement. Let's introduce _c suffix versions of those functions where the caller passes in a talloc context from which the output buffer shall be allocated. Change-Id: I8481c19b68ff67cfa22abb93c405ebcfcb0ab19b

* add osmo_use_count APINeels Hofmeyr2019-04-082-0/+229
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Hofmeyr2019-04-082-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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

* 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
