* add osmo_hexdump_buf() and testNeels Hofmeyr2019-01-284-11/+163
| | | | | | | | | | | | | | | | | | 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 Hofmeyr2019-01-287-0/+645
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Work around bogus gcc-8.2 array-bounds warning/errorHarald Welte2019-01-222-1/+21
| | | | | | | | | | | | | | | | | | | | | | gcc-8.2 is printing the following warning, which is an error when used -Werror like our --enable-werror: In file included from gprs_bssgp.c:34: In function ‘tl16v_put’, inlined from ‘tvlv_put.part.3’ at ../../include/osmocom/gsm/tlv.h:156:9, inlined from ‘tvlv_put’ at ../../include/osmocom/gsm/tlv.h:147:24, inlined from ‘msgb_tvlv_push’ at ../../include/osmocom/gsm/tlv.h:386:2, inlined from ‘bssgp_tx_dl_ud’ at gprs_bssgp.c:1162:4: ../../include/osmocom/gsm/tlv.h:131:2: error: ‘memcpy’ forming offset [12, 130] is out of the bounds [0, 11] of object ‘mi’ with type ‘uint8_t[11]’ {aka ‘unsigned char[11]’} [-Werror=array-bounds] memcpy(buf, val, len); Where "130" seems to be the maximum value of uint8_t, shifted right one + 2. But even as we use strnlen() with "16" as maximum upper bound, gcc still believes there's a way that the return value of gsm48_generate_mid_from_imsi() could be 130. In fact, even the newly-added OSMO_ASSERT() inside gsm48_generate_mid() doesn't help and gcc still insists there is a problem :( Change-Id: I0a06daa19b7b5b5badbb8b3d81a54c45b88a60ec
* constrain gsm48_generate_mid() output array boundsHarald Welte2019-01-224-7/+12
| | | | | | | | | | | 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

* Rename msgb_wrap_with_TL()Max2019-01-212-10/+10
| | | | | | | | | | | | | | | 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.

* gsm29118: fix coverity issuesPhilipp Maier2019-01-181-1/+6
| | | | | | | | | | | | | The function msgb_sgsap_name_put() assignes the return code of osmo_apn_from_str() directly to len. Len is an uint8_t and the return code an int. If osmo_apn_from_str() returns -1. Len would become 0xFF causing a buffer overrun with msgb_tlv_put. Lets use the proper type to catch the return code and check it before using it as length.

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.

* port rest octets encoding code from osmo-bscStefan Sperling2019-01-125-0/+1084
| | | | | | | | | | | | | | | | | | | | | | | | | | As part of fixing issue OS#3075, we want to migrate support for encoding system information from osmo-bsc to libosmocore. This change ports osmo-bsc code for encoding SI rest octets. The conversion was a bit tricky in some places because some functions receive a 'struct gsm_bts' parameter in osmo-bsc. In this libosmocore version, such functions expect parameters which correspond to the individual fields of 'struct gsm_bts' which are used by these functions. Several structs from osmo-bsc's system_information.h are now also declared in libosmocore headers, with an added osmo_ prefix to avoid collisions with existing definitions in osmo-bsc. Some helpers were ported from osmo-bsc's system_information.c to libosmocore's gsm48_rest_octets.c. Contrary to osmo-bsc's implementation they are now only visible within this file. Unfortunately, this code ported from osmo-bsc lacks unit tests. Change-Id: I47888965ab11bba1186c21987f1365c9270abeab Related: OS#3075

| | | | | | | | | | | | | | As part of fixing issue OS#3075, we want to migrate support for encoding system information from osmo-bsc to libosmocore.

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

| | | | | | | | | | | | | | Note that OSMO_GSUP_IMEI_RESULT_ACK is 0 on the wire, although the enum value is 1. Same with NACK (1 on wire, enum 2). I had implemented enum osmo_gsup_imei_result after enum osmo_gsup_cancel_type above, where this comment exists as well, and I incorrectly assumed that enum osmo_gsup_cn_domain in the middle was also implemented this way and therefore adding the comments to each enum would be redundant.

Since GSUP is more about MAP messages, I'm calling the enum osmo_rat_type. Rationale: osmo-msc and osmo-sgsn want to tell the osmo-hlr which RAT a subscriber is calling on.

| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | Implement necessary messages for Procedure Check_IMEI_VLR (TS 23.018 Chapter 7.1.2.9). This lets the VLR ask the EIR to check if an IMEI is valid. In the Osmocom stack, we don't have an EIR and this request will be handled by the HLR. We will be able to store the IMEI in the HLR as side-effect (OS#2541).
