2019-03-27Doxygen: fix documentation of rate_ctr_for_each_counter()Vadim Yanitskiy1-1/+1
Doxygen was confused by duplicated documentation for both definition and declaration of rate_ctr_for_each_counter(). Moreover, both variants contained some mistakes. Let's avoid this duplication and keep the only (corrected) one. Change-Id: Icca2d4a95bd5f96ae85a86909ec90fb8677cacf3

Previous logic regarding logging of verification and mangling of rate_ctr groups made it difficult to debug when an issue occurrs. Change-Id: I992d165cab5ee6ca9b5b7e4a2210a0951954bd34

2017-12-20rate_ctr: fix osmo-sgsn DoS: don't return NULL on already used indexNeels Hofmeyr1-3/+26
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).

2017-11-20rate_ctr: fix mem leak for mangled descNeels Hofmeyr1-9/+9
Using the NULL context creates mem leaks that bother sanitizer builds. Allocate as talloc "child" of the rate_ctr_group, so that the mangled desc (if any) gets freed when the rate_ctr group is freed. Remove the comment concerning osmo-msc: the way to fix the unexpected talloc state in osmo-msc tests is to have no invalid rate counter names in osmo-msc. See Ib1db8e3dc6c833174f1b0b1ca051b0861f477408 (osmo-msc). Change-Id: Ief9abfeb78b7706200bcc6aaa5dcb04fbeaa9b5b

In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduced a variable de-reference before we check if it's NULL. Let's reorder the statements to avoid this. Fixes: Coverity CID#178219 Change-Id: I99265a7ee76f85c479543c19ce8c05ce5d43ae69
2017-10-24rate_ctr: Enforce counter (and ctr_group) names are valid identifiersHarald Welte1-1/+117
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.

2017-06-23doxygen: unify use of \file across the boardNeels Hofmeyr1-7/+3
Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

2017-06-23doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr1-10/+10
Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
2017-06-12update/extend doxygen documentationHarald Welte1-0/+1
It's a pity that even with this patch we still are fare away from having the whole API documented. However, at least we have a more solid foundation. Updates not only extend the documentation, but also make sure it is rendered properly in the doxygen HTML. Change-Id: I1344bd1a6869fb00de7c1899a8db93bba9bafce3
2017-05-09timer: add osmo_timer_setup()Pablo Neira Ayuso1-1/+1
Add a new function timer function to set up the timer, similar to what we have in the Linux kernel. This patch also converts existing opencoded timer setup in the libosmocore tree as initial client of this new function. This patch implicitly removes function callback passed by reference that defeat compile time type validation. Compile-tested only, but I ran make check that reports success when testing timer infrastructure. Change-Id: I2fa49972ecaab3748b25168b26d92034e9145666

This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
2015-11-26stats: Add TODO comment to rate_ctrJacob Erlbeck1-0/+3
Currently the counters are scanned twice, once for interval computation and once for reporting. This adds a reminder to move the interval computation code to a special stats reporter which just shall update the fields. Sponsored-by: On-Waves ehf
2015-10-28core: Extend rate_ctr by helper functionsJacob Erlbeck1-0/+41
For global value reporting, some additional helper functions are needed. The statsd protocol expects differential counter values, which are currently not provided by rate_ctr (except for s/m/h/d intervals). This commit adds several helper functions to rate_ctr: - rate_ctr_difference returns the counter delta since the last call to this function for a given counter - rate_ctr_for_each_counter iterates through each counter of a group - rate_ctr_for_each_group iterates through all globally registered counter groups Note that the rate_ctr_difference function can only be used by a single backend, since it modifies the 'previous' field in the rate_ctr obj.

This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core. This has been proposed by Harald Welte and Sylvain Munaunt. Tested with `make distcheck'. Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2010-12-20rate_ctr: No need to include the inttypes.hHolger Hans Peter Freyther1-1/+0
There should not be any u_int*_t types in this file, no need to include this file. It is breaking compilation with the last x86 build of GNU ARM for GCC 3.4.
2010-05-13[rate_ctr] always 'overflow' in next larger inetrval when interval endsHarald Welte1-0/+6
If a second ends, we add the number of events in that just-ended second to the number of events in the currently running minute. The same happens at the end of a minute: We add the number of events in that just-ended minute into the number of events of the still-running hour, etc. This gives a much more meaningful numbers and we don't end up with "12 events per second, but 0 events per minute" kind of situations anymore.

2010-05-13Add new 'rate counter' implementation to libosmocoreHarald Welte1-0/+124
A 'rate counter' is a counter that counts events but also keeps track of the rate of events (per second, minute, hour and day). 'rate counters' are generally abstracted in 'rate counter groups', which are instances of a 'rate counter group description'. This way we can have e.g. a description describing what kind of counters a BTS (or TRX) has - and we can then create one instance of that group for every BTS or TRX that exists.
