- update to 21.2.4: - Changes for 21.2.4: * http://erlang.org/download/OTP-21.2.4.README * erts: Fix bug where doing a gen_tcp:send on a socket with delay_send set to true could cause a segfault if the other side closes the connection. Bug was introduced in erts-10.2 (OTP-21.2). * erts: Fix a race condition when a port program closes that could result in the next started port to hang during startup. Bug was introduced in erts-10.0 (OTP-21.0). * erts: Fix a bug where polling for external events could be delayed for a very long time if all active schedulers were 100% loaded. Bug was introduced in erts-10.2 (OTP-21.2). * inets: Make sure ipv6 addresses with brackets in URIs are converted correctly before passing to lower level functions like gen_tcp and ssl functions. Could cause connection to fail. - update to 21.2.3: - Changes for 21.2.3: * http://erlang.org/download/OTP-21.2.3.README * compiler: An optimization that avoided allocation of a stack frame for some case expressions was introduced in OTP 21. (ERL-504/OTP-14808) It turns out that in rare circumstances, this optimization is not safe. Therefore, this optimization has been disabled. * erts: Fixed a crash when dangling files were closed after init:restart/0. * erts: A bug that could cause dirty schedulers to become unresponsive has been fixed. * ssl: Fix encoding of the SRP extension length field in ssl. The old encoding of the SRP extension length could cause interoperability problems with third party SSL implementations when SRP was used. * ssl: Guarantee active once data delivery, handling TCP stream properly. Correct gen_statem returns for some error cases * xmerl: The charset detection parsing crash in some cases when the XML directive is not syntactic correct.

# Erlang in openSUSE ## Erlang Port-mapper Daemon and systemd Erlang Port-mapper Daemon in openSUSE uses systemd socket-activation. In order to fulfill security considerations, EPMd listens on loop-back interface by default. This is enough to run rabbitmq-server, ejabberd and user-started beam processes. For clustering, please, use ```/etc/systemd/system/epmd.socket.d/``` to configure interfaces to listen on. See man systemd.unit(5) for details. ### Upgrading from sysvinit ```/etc/sysconfig/erlang``` has no effect now, to configure EPMd use systemd capabilities instead. ### Example 1: change port Create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=127.0.0.1:4444 ``` The first line is to discard vendor configuration. The second line will change the port number to listen on to 4444. ### Example 2: enable external interface To enable accepting external connections to EPMd, create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=0.0.0.0:4369 ```
