| | | | | | | In Change-Id I61f452208088dc7097165deecef7c058ebb4bd4e we introduced the #defines but didn't introduce the new log_info_cat information. Change-Id: I218aa4cb1fc7640a75663be29bac672dfa8770f5
* logging: fail gracefully if log_info() was not calledHarald Welte2017-03-161-0/+21
| | | | | | | | The logging code crashes if osmo_log_info is not set, which is typically achieved by calling log_init(). Let's fail with a reasonable assert and error message if the user forgets that. Change-Id: If3007860d2efe6ea9aec27e7d7439d44a7cd19c2
* logging.h: fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr2017-02-231-8/+8
| | | | | | | | | | | | | | | My recent logging patch was merged to master a bit too soon. Accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING". libosmocore will not be backwards-compatible with the few commits from change-id I5c343630020f4b108099696fd96c2111614c8067 up to this one. This and following commits are backwards compatible with those before that short window.

* logging: centrally define ctx and filter indexesNeels Hofmeyr2017-02-221-7/+14
| | | | | | | | | | | | | | | | | | | | | | | It is too easy for calling code to use the same filter and context indexes for different filters and structs. For example, openbsc's IMSI filter and libgb's GPRS_BVC filter both fall on index 1 even though there are plenty more indexes to choose from. To alleviate this, have one central definition here, sort of like ports.h does for VTY and CTRL port numbers. Add static asserts to make sure the indexes fit in the available array and bit mask space. Calling code like openbsc.git and osmo-pcu need adjustments and/or should move to using these enum values instead of their local definitions. Taking this opportunity to also prepare for a split of struct gsm_subscriber in openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter index constants for both subscriber types. Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its use by (1 << LOGGING_FILTER_ALL). Change-Id: I5c343630020f4b108099696fd96c2111614c8067

* fix logging: log_set_category_filter() for internal DL* logging catsNeels Hofmeyr2016-12-121-1/+2
| | | | | | | | | | | | | | | | | | In log_set_category_filter(), passing a negative index lead to memory corruption. Particularly dangerous since the internal logging categories have negative values. Fix: apply map_subsys() to interpret negative values as internal logging categories. As a side effect, out-of-bounds logging categories will be mapped to DLGLOBAL instead of being dropped. Fix the expectations in logging_test to match the fixed bug. While at it also guard against a NULL logging target. Change-Id: Ib0725b22bc39498c6b3970a61eb3339cf56d19f1
* fix logging: out-of-bounds check should end with user categoriesNeels Hofmeyr2016-12-121-0/+5
| | | | | | | | | | | | | To check category bounds, rather use num_cat_user, to redirect all semantically unknown categories to DLGLOBAL. Adjust logging_test expectations accordingly: "(d)" is now also shown. Note: subsys is and needs to be signed, while num_cat* are unsigned. Thus for a negative subsys, 'subsys >= num_cat_user' practically always yields true. Pay close attention to signedness and check upper bound only for positive values. Change-Id: I4a952b759f30d90fbfb81fedcfc56a8092ea18c1
* fix logging: also catch first out-of-bounds logging catNeels Hofmeyr2016-12-121-1/+3
| | | | | | | | | | In map_subsys(), fix the '>' condition to '>=' for array bounds checking. Also make the bounds checking more strict: after both invocations of subsys_lib2index(), re-check validity of the array index. If the final index is still wrong, which should never happen, exit by assertion. Change-Id: I7ca1a1d47724e40350f1c4dfebe90bad01c965f9
* fix logging: redirection to DLGLOBAL for invalid categoriesNeels Hofmeyr2016-12-121-1/+8
| | | | | | | | | | | For out-of-bounds logging categories, redirect to the proper DLGLOBAL array index instead of returning -1. Adjust test expectation which shows that the bugs tested for are fixed. Note: there are separate bounds checking problems, left for another patch. Change-Id: I6ea9a59e005a22e0305454291714fdb9531c346b
* import oap message parsing / encoding from openbsc.git; AGPL->GPLHarald Welte2016-12-111-0/+5
| | | | | | | | | | | | | | | | | | | In the process, also: * Change the license from AGPLv3 to GPLv2-or-later; * correct spelling of 'sysmocom' to lowercase; * add '2016' to the copyright; * rename to osmo_*; * add API docs; * add logging category DLOAP: define id and add to internal_cat; * redirect all oap.c logging to DLOAP. A unit test will follow in a subsequent patch, since it needs a minor tweak for decoding of boolean values. The related openbsc change-id is I2f06aaa6eb54eafa860cfed8e72e41d82ff1c4cf.

* fix: DLGSUP logging category "unusable"Neels Hofmeyr2016-12-111-0/+5
| | | | | | | | | | | | | | | | | | | All DL* categories are typically negative, but DLGSUP isn't, and it's also not in libosmocore's internal_cat array. See: 3b6fb0880c3ab1e23a3d7d738d073b00c2a794c2 This means that a program using DLGSUP has to include DLGSUP in its own logging cat array (typically not needed for DL* categories), which means for osmo-nitb that DLGSUP (11) replaces DMGCP (also 11), and DMGCP becomes unusable. Fix this: make DLGSUP -11 and include in internal_cat. In gsup_test.c, no longer add DLGSUP to the logging categories array. External follow-ups are otherwise needed only in osmo-hlr.git and some pending patches for openbsc (Id3938267fa062e1a997d3704cd678874306f86ee). Change-Id: Id974c7be158e4d60421a98110f5c807aefd31119
* Implement GSMTAP log targetHarald Welte2016-12-091-2/+2
| | | | | | | This target wraps the to-be-logged string (With metadata) into a GSMTAP packet and sends it to the configured destination address. Change-Id: I9a7e72b8c9c6f6f2d76d1ea2332dcdee12394625
* logging: Extend log_target with call-back for un-formatted log lineHarald Welte2016-12-021-1/+4
| | | | | | | | | | | Some targets might not want to receive only an opaque, pre-formatted string, but rather the unformatted arguments with metadata like sub-system/level/file/line. We solve this by introducing a log_target->output_raw() function pointer. If a target specifies this function, it takes precedence over the regular log_target->output() function.

* add osmo_gettimeofday as a shim around gettimeofdayNeels Hofmeyr2016-09-221-1/+2

* Update doxygen annotations in libosmocoreHarald Welte2016-05-051-10/+47
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
* Add log_fini() function to release all memory allocated by logging frameworkHarald Welte2016-05-051-0/+15
| | | | | This is e.g. quite useful to call at the end of test code, in order to show that all memory allocated actually is released before exit().

* logging: Remove unused variable after recent changesHolger Hans Peter Freyther2016-02-291-1/+0
| | | | | The variable is not used anymore as the decision is done in the newly added check_log_to_target method.
* logging: Move the filter check up as wellHolger Hans Peter Freyther2016-02-291-11/+9
| | | | | | There doesn't seem to be a reason not to check the filter. Update and extend the test. Currently the filter function will be called once for the log check and once for the output of it.
* logging: Remove some code duplicationHolger Hans Peter Freyther2016-02-291-37/+37
| | | | | | Extract the mapping of the subsystem number and the checking for the loglevel to a inline method that is shared between the new and old.
* log: Add log_check_level functionJacob Erlbeck2016-02-291-0/+39
| | | | | | | | | | | | | | | | | | This commit adds this predicate function which can be used to avoid the execution of code if a certain log level is not enabled. The function will only return 0 (false), if it is sure that a logging call for the same facility and level will not produce any output. This safety criterion shall ensure, that no logging output is lost due to the use of this predicate as a guard. On the other hand, even if the predicate returns != 0 (true), no logging output might get generated by a similar logging command. Note that the current implementation is not focussed on performance, which could be improved by using a lookup table instead of iterating through every target. Sponsored-by: On-Waves ehf
* log: Add new DLSTATS log levelJacob Erlbeck2015-11-021-0/+5
| | | | | | | | This log level is used by the stats subsystem log reporter to report statistics to level INFO. Note that the default level of DLSTATS is NOTICE. Sponsored-by: On-Waves ehf
* logging: Implement subsecond resolution of extended timestampsJacob Erlbeck2015-03-181-4/+7
| | | | | | | | | | | | | Currently when using 'logging print extended-timestamp 1', the subsecond part (milliseconds) of the printed timestamp is always 0. This makes it difficult to correlate log entries with PCAP file entries if there are many of them per second. This patch changes _output in logging.c to use gettimeofday() instead of time() when extended timestamps are enabled and replaces the '000' by the milliseconds computed from tv_usec.

* log: "logging level everything" is a badly named option.Holger Hans Peter Freyther2014-12-281-1/+1
| | | | | | | | | | We tried to fix it but it isn't that easy. The original fix was cd6ed82d1ff48f47ad9e33e6322df62896a76ed5 but we had to revert it as "everything" is present/used in existing config files. If we ever change the ABI we can make everything be something that is > 0. For now use a wording that makes it obvious that people should not use "everything".
* logging: Call color only once and use the resultHolger Hans Peter Freyther2014-12-051-1/+1
| | | | | | First we check if a color is defined and then we call it again and use the result. Avoid the second call and use the result of the previous call.
* logging: Make it possible to print category/subsys and timestampsHolger Hans Peter Freyther2014-12-051-1/+49
| | | | | | | | | | | | We want to see from which category/subsystem a certain log message is coming from and use a different timestamp format as well. Add two new bitfields. This doesn't change the size of the structure and on 32bit we still have 27bits left. The extended timestamp will take preference over the current and default timestamp format. Fixes: SYS#602
* gtp: Add a global region for the gtp library of OpenGGSNHolger Hans Peter Freyther2014-12-041-0/+5
| | | | | We want to use libosmocore/libosmovty in the GGSN sourcecode and reserve a global region here.

* logging: Copy the filter_fn and fix the IMSI filter in OpenBSCHolger Hans Peter Freyther2013-12-291-0/+1
| | | | | | | The filter_fn has not been copied into the new structure breaking the imsi and other filters in OpenBSC. Looking at the code we should also introduce a callback for the reset of the context so we could use subscr_get/subscr_put on the subscriber structure.

* Follow up fix for the log level "everything"Holger Hans Peter Freyther2013-02-271-0/+3
| | | | | | | | | | | | Commit cd6ed82d1ff48f47ad9e33e6322df62896a76ed5 made "EVERYTHING" map to LOGL_DEBUG but when writing out the configuration the following would be written: logging level all unknown 0x0 This happend because no string was found for the value 0. Address it by adding a legacy check for 0 and write out the str from the index 0. Currently this is "EVERYTHING".
* Fix log level "everything" and make it equal to "debug"Harald Welte2013-02-191-1/+1
| | | | | | As Holger points out "logging level XXX everything" wasn't working, as it sets category->loglevel to 0, which is checked in osmo_vlogp() and will never get logged.
