* tests: coding_test: Fix compilation with -O0Pau Espin Pedrol2018-02-081-2/+2
| | | | | | | | | | | | | | | | | inline keyword is a hint for the compiler to inline the function, but it's not mandatory. If no static or extern is specified, the definition is only visible in the current unit but the identifier still has external linkage. When running with -O0 it seems the compiler (gcc 7.2.1) decides to use the external linkage but at the same time it seems it's not generating the function symbol. Fix it by explicitly stating that we want to use static linking for this function. coding/coding_test.o: In function `test_xcch': libosmocore/tests/coding/coding_test.c:86: undefined reference to `dump_ubits' libosmocore/tests/coding/coding_test.c:87: undefined reference to `dump_sbits' Change-Id: I18018adec05ce1c2ddbca38653311d74c7454ce8

* GSUP: don't fail test on first errorMax2018-01-222-4/+30
| | | | | | | | | | Instead of forcing test failure via assert on first error encountered, let it run until completion and print detailed error log. This simplifies troubleshooting by letting user to see more errors from single run and more details on each of the errors. Update test output with explicit test results.

* tests/ussd: prevent uninitialized memory accessVadim Yanitskiy2018-01-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously an incorrect length value was passed to both gsm_7bit_decode_n_ussd() and gsm_7bit_encode_n_ussd() functions during test_7bit_ussd() execution, due to: octets_written = strlen(decoded); The problem is that a 7-bit encoded string takes less memory than its 8-bit equivalent. So, here strlen() returns one-byte bigger value, that octets_written is. This then causes the uninitialized memory access.

| | | | | | | | | | | When a bad GSM voice frame is received, it's being replaced by a silence frame. This may cause unpleasant audio effects. This change implements a functionality to craft a replacement frame from the last known good frame. Currently, only FR is supported, support for other codecs may be added latter.

* Add function to properly encode RAIMax2018-01-082-7/+6
| | | | | | | | | | | | | Add gsm48_encode_ra() which takes appropriate struct as [out] parameter instead of generic buffer. Using uint8_t buffer instead of proper struct type prooved to be error-prone - see Coverity CID57877, CID57876. Old gsm48_construct_ra() is made into tiny wrapper around new function. The test output is adjusted because of the change in function return value which was constant and hence ignored anyway. Related: OS#1640 Change-Id: I31f9605277f4945f207c2c44ff82e62399f8db74
* ctrl: tighten CTRL input parsingNeels Hofmeyr2017-12-203-114/+74
| | | | | | | | | | | | | | | | Validate that incoming CTRL commands... - have decimal IDs, - return error on trailing characters, - have invalid characters in variable identifiers, - send detailed error messages as reply to the requestor.

* rate_ctr: fix osmo-sgsn DoS: don't return NULL on already used indexNeels Hofmeyr2017-12-201-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent patch I563764af1d28043e909234ebb048239125ce6ecd introduced returning NULL from rate_ctr_group_alloc() when the index passed already exists. Instead of returning NULL, find an unused group index and use that, adjust the error message. In stats_test.c, adjust, and also assert allocated counter group indexes everywhere. Rationale: The original patch causes osmo-sgsn to crash as soon as the second subscriber attempts to establish an MM context. Of course osmo-sgsn is wrong to a) fail to check a NULL return value and crash and b) to fail to allocate an MM context just because the rate counter group could not be allocated (it still rejects the MM context completely if rate_ctr_group_alloc() fails). Nevertheless, the price we pay for rate counter correctness is, at least in this instance, way too high: osmo-sgsn becomes completely unusable for more than one subscriber. Numerous other places exist where rate_ctr_group_alloc() is called with a constant index number; from a quick grep magic I found these possible breaking points: osmo-sgsn/src/gprs/gb_proxy.c:1431: cfg->ctrg = rate_ctr_group_alloc(tall_bsc_ctx, &global_ctrg_desc, 0); osmo-sgsn/src/gprs/gprs_sgsn.c:139: sgsn->rate_ctrs = rate_ctr_group_alloc(tall_bsc_ctx, &sgsn_ctrg_desc, 0); osmo-sgsn/src/gprs/gprs_sgsn.c:270: ctx->ctrg = rate_ctr_group_alloc(ctx, &mmctx_ctrg_desc, 0); osmo-sgsn/src/gprs/gtphub.c:888: b->counters_io = rate_ctr_group_alloc(osmo_gtphub_ctx, &gtphub_ctrg_io_desc, 0); osmo-bsc/src/libfilter/bsc_msg_acc.c:87: lst->stats = rate_ctr_group_alloc(lst, &bsc_cfg_acc_list_desc, 0); osmo-pcu/src/bts.cpp:228: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:793: tbf->m_ctrs = rate_ctr_group_alloc(tbf, &tbf_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:879: tbf->m_ul_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_egprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:880: tbf->m_ul_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_gprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:970: tbf->m_dl_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_egprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:977: tbf->m_dl_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_gprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:1475: ul_tbf->m_ctrs = rate_ctr_group_alloc(ul_tbf, &tbf_ctrg_desc, 0); osmo-pcu/src/bts.cpp:226: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 1); We can fix all of these callers and then reconsider returning NULL, but IMO even into the future, rate counter group indexes are not something worth failing to provide service for. For future bugs we should keep the automatic index picking in case of index collisions. We will get an error message barfed and can fix the issue in our own time, while the application remains completely usable, and even the rate counters can still be queried (at wrong indexes, but life is tough).

* ctrl: on parse errors, return a detailed message to senderNeels Hofmeyr2017-12-181-1/+1
| | | | | | | | | | | The recently added ctrl_cmd_parse2() returns non-NULL cmd with error messages upon parsing errors.

Retain the previous "Command parser error" reply only in case ctrl_cmd_parse2() should return NULL, which shouldn't actually happen at all. Change-Id: Ie35a02555b76913bb12734a76fc40fde7ffb244d

* ctrl: fix mem leak when handling GET_REPLY and SET_REPLYNeels Hofmeyr2017-12-182-5/+2
| | | | | | | | | | | | In ctrl_handle_msg() (code recently propagated from handle_control_read()), talloc_free() the parsed ctrl_cmd in all code paths. In particular, a free was missing in case ctrl_cmd_handle() returns CTRL_CMD_HANDLED. CTRL_CMD_HANDLED is triggered by GET_REPLY / SET_REPLY parsing, as show by ctrl_test.c. With the memleak fixed, adjust expected test output and make a detected mem leak abort the test immediately. Change-Id: Id583b413f8b8bd16e5cf92a8a9e8663903646381

* utils: add osmo_escape_str()Neels Hofmeyr2017-12-182-0/+77
| | | | | | | | | | | | | To report invalid characters in identifiers, it is desirable to escape any weird characters. Otherwise we might print stray newlines or control characters in the log output. ctrl_test.c already uses a print_escaped() function, which will be replaced by osmo_escape_str() in a subsequent patch. control_cmd.c will use osmo_escape_str() to log invalid identifiers.

* Fix malformed Abis/RSL messages with extra L3 Information fieldPau Espin Pedrol2017-12-102-8/+2
| | | | | | | | | | | | | | | | | Some Abis/RSL messages such as "Release Indication" contained 3 extra bytes from an L3 Information header which should not be there according to specs in GSM 08.58 (section 8.3 "Radio link layer management messages"). Other RSL messages were affected by the same issue, except for "Establish Indication", which had already a workaround in send_rslms_dlsap. This commit fixes the issue in a generic way, removes the "Establish Indication" and fixes the test accounting for the bug, as it otherwise fails after applying the changes.

* gprs_bssgp: bssgp_fc_in(): fix mem leak on queue overflowNeels Hofmeyr2017-11-202-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All successful and all error code paths of bssgp_fc_in() free the msgb, except the code path calling fc_enqueue() when the msg is dropped (due to queue being full, or failure to allocate). Callers could theoretically catch the -ENOSPC return value and discard the msgb. However, in other code paths, a callback's return value is returned, which is expected to free the msgb, so such callback would have to never return -ENOSPC when it freed the msgb. Much simpler semantics would be to free the msgb in every code path, no matter which kind of error occurred. Who is currently calling bssgp_fc_in and how do they handle the return value? - bssgp_fc_test.c ignores the return value (and hits a mem leak aka sanitizer build failure if the queue is full). - fc_timer_cb() ignores the return value. - bssgp_tx_dl_ud() returns the bssgp_fc_in() rc. - which is returned by a cascade of functions leading up to being returned, for example, by gprs_llgmm_reset(), which is usually called with ignored return code. At this point it is already fairly clear that bssgp_fc_in() should always free the msgb, since the callers don't seem to distinguish even between error or success, let alone between -ENOSPC or other errors. bssgp_fc_test: assert that no msgbs remain unfreed after the tests. Adjust expected results. Helps fix sanitizer build on debian 9. Change-Id: I00c62a104baeaad6a85883c380259c469aebf0df

If we create the msgb context and *don't* clean it up in the end, the sanitizer build fails because the context root is not cleaned up. Easiest is to actually allocate all msgb at NULL ctx, because then any msgb that aren't cleaned up properly would still linger, while we don't leave a root ctx that we need to clean up either.

| | | | | | | | The rate_ctr.c code would do this mangling automatically, but let's avoid using this from new versions of our code for simplicity/explicitness. Change-Id: I24a556f447cfac25efb6e83cac2d0c2972d98fe3
* rate_ctr: Enforce counter (and ctr_group) names are valid identifiersHarald Welte2017-10-242-43/+43
| | | | | | | | | | | | | | As rate counters are automatically exposed on the CTRL interface, we need to make sure they don't contain special characters such as '.' which are not permitted/supported by CTRL. In order to be able to run old versions of osmocom programs with libosmocore versions after this commit, we introduce some special name mangling: Any '.' in the names are replaced with ':' during counter group registration, if valid identifiers can be obtained this way.

| | | | | | | | | | | | This function is actively used by OsmoPCU but have not been covered by tests so far. The test code is based on Minh-Quang Nguyen <minh-quang.nguyen@nutaq.com> submission with some modifications. The test's FIXME will be addressed in follow-up patches.
