[kamailio/kamailio] Add optional parameter to ds_is_from_list() to check only active GW (#1908)

by pwakano

### Description Currently ds_is_from_list() matches all GWs in the dispatcher list, not considering if the GW is disabled or not. It might have situation where a GW is permanently disabled but can't be removed (because of CDR references for instance). In this case it is not desired to match a disabled GW in the test. The function should accept a new parameter which will tell if it should or not match disabled GWs. For backward compatibility, it should not be a mandatory parameter and its default value should be to match disabled GW (as it is today). ### Expected behavior ds_is_from_list() should return false in case it matches a disabled GW and the new parameter tells not to match disabled GWs. -- You are receiving this because you are subscribed to this thread.

Info: initialization of libssl 1.1.+ with PTHREAD_PROCESS_SHARED attribute for pthread mutex and rwlock

by Daniel-Constantin Mierla

Hello, after couple of months waiting for feedback about the workaround with the preloaded shared library to set the PTHREAD_PROCESS_SHARED attribute for pthread mutex/rwlock in order to avoid deadlocks and as it seems to be the solution, I just pushed a few commits to move that code in the core of kamailio. It this way the initialization with the PTHREAD_PROCESS_SHARED attribute is done by default when libssl v1.1 is detected at compile time, without the need of using the approach with a preloaded library. The shared library is still kept in the tls module: * https://github.com/kamailio/kamailio/tree/master/src/modules/tls/utils/open… Probably is going to be removed in the near future. I am asking the community members that use Kamailio on systems with libssl v1.1+ to test the master branch and give feedback. The master branch is anyhow in testing phase for preparing the next major release v5.3.0, so it will help for that as well. If no issue is going to be reported soon, the commits will be backported to stable branches, to re-enable smooth use of Kamailio with libssl v1.1+. When libssl v1.1+ is detected, the core links with pthread, but that was already present in the Makefiles.defs for different compile options. The pthread more or less a default library on linuxes/unixes, so this should not introduce any major dependency to the Kamailio core.
