* logging: Introduce mutex API to manage log_target in multi-thread envsPau Espin Pedrol2019-10-0912-100/+709
| | | | | | | | | | | | | | | | | | | | log_enable_multithread() enables use of locks inside the implementation. Lock use is disabled by default, this way only multi-thread processes need to enable it and suffer related complexity/performance penalties. Locks are required around osmo_log_target_list and items inside it, since targets can be used, modified and deleted by different threads concurrently (for instance, user writing "logging disable" in VTY while another thread is willing to write into that target). Multithread apps and libraries aiming at being used in multithread apps should update their code to use the locks introduced here when containing code iterating over osmo_log_target_list explictly or implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

* vty: Optionally Set/replace cfg file during cmd 'write file'Pau Espin Pedrol2019-10-071-2/+6
| | | | | | | | | | | This way if the process is started with no file associated (eg. no -c param and default cfg path doesn't exist), config can be later saved into a file by passing the parameter. Otherwise, until now this message was displayed: Can't save to configuration file, using vtysh. Related: OS#4024 Change-Id: I38edcf902a08b6bd0ebb9aa6fc1a7041421af525

* gsup: add OSMO_GSUP_SUPPORTED_RAT_TYPES_IE and OSMO_GSUP_CURRENT_RAT_TYPE_IENeels Hofmeyr2019-09-283-7/+49
| | | | | | | | | | | | | | OSMO_GSUP_SUPPORTED_RAT_TYPES_IE corresponds to the Supported RAT Types Indicator from 3GPP TS 29.002. See 8.1.2 MAP_UPDATE_LOCATION service, which indicates the capabilities of the MSC/VLR to the HLR. So far, have room for eight RAT types in the gsup_msg. That is an arbitrary random choice without any rationale. OSMO_GSUP_CURRENT_RAT_TYPE_IE is useful to communicate the currently used RAN / RAT type of the current subscriber during Location Updating Request.

| | | | | | | | | | | | | | | | Projects not containing libraries may also want to contain a TODO-RELEASE in order to write down when a new API available only on libosmoXYZ current master (hence configure.ac and debian cannot be updated during the patch using the API until the APIs are available in a new release). This way, during release process of the project, the maintainer can see that a release of libosmoXYZ is needed beforehand and then update configure.ac of project accordingly with the new version of libosmoXYZ. Furthermore, we want to update the file only if mode DRY_RUN is not selected. Change-Id: I409b7eb8c23d21473f25dd2000f5d4447b24adb9
* ecu_fr: increase test coverage for FR ECU implementationPhilipp Maier2019-09-203-2/+88
| | | | | | | | | | | | | The ECU implementation for FR is currently tested by calling the related functions directly and by using the generic ECU abstraction layer. However, the test "test_fr_concealment" only tests directly. Lets add a version that uses the generic ECU abstraction layer as well. The generic ECU abstraction layer obsolets the public API functions osmo_ecu_fr_reset() and osmo_ecu_fr_conceal(), lets tag those functions as dprecated.

| | | | | | | | | | | | | | | | | | | | We don't want to expose the details of a given ECU implementation to the user (e.g. osmo-bts), but have a generic abstraction layer where an ECU implementation can simply register a few call-back functions with the generic core. As the developer and copyright holder of the related code, I hereby state that any ECU implementation using 'struct osmo_ecu_ops' and registering with the 'osmo_ecu_register()' function shall not be considered as a derivative work under any applicable copyright law; the copyleft terms of GPLv2 shall hence not apply to any such ECU implementation. The intent of the above exception is to allow anyone to combine third party Error Concealment Unit implementations with libosmocore, including but not limited to such published by ETSI.

| | | | | | | | | | | | | | | | | | | | When a VTY closes, dispatch the VTY_CLOSED signal before tearing down the VTY buffer and fd. In particular this fixes: - a crash during telnet_close_client(), invoked by the VTY_CLOSED event, which logs to DLGLOBAL and uses vty->obuf that, so far, vty_close() had already unallocated earlier (OS#4164). - the logging about closing a telnet session so far logged: DLGLOBAL INFO Closing telnet connection r=NULL<->l=NULL By dispatching the VTY_CLOSED event while the fd is still valid, we instead get the actual connection IP address and port being closed: DLGLOBAL INFO Closing telnet connection r=127.0.0.1:36708<->l=127.0.0.1:4258 Related: OS#4164 Change-Id: I1d235cbfbfb9aaf411316642c7bcfac12106df44

* osmo_tdef_get(): allow passing -1 as default timeoutNeels Hofmeyr2019-08-153-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | The intention of osmo_tdef_get()'s val_if_not_present argument was to return a default timeout, or to optionally abort the program for missing timer definitions if the default timeout is < 0. This was the case in the original implementation of this API in osmo-bsc, but in the migration to libosmocore, the argument was by accident changed to an unsigned type. In consequence, the assertion in the implementation that was intended to abort the program seemed bogus to coverity, and was fixed by removal in I7a544d2d43b83135def296674f777e48fe5fd80a -- the wrong direction, as is obvious from the API doc for osmo_tdef_get(). Note that osmo-bsc master passes -1 in various places and expects the program-abort behavior that was missing from the libosmocore implementation. Change the val_if_not_present argument to a signed type, and revert removal of the assertion, so that passing -1 has the effect described in the API doc: program abort on missing timer definition. This bug was not detected because it is hard to write tests that expect a program abort to happen, hence no tests for this API feature exist.
