- Changes for 22.1.7 * http://erlang.org/download/OTP-22.1.7.README * compiler: Fixed a performance bug that caused repeated matches of large records to take a very long time to compile. * erts: A literal area could prematurely be released before all uses of it had been removed. This occurred either when a terminating process had a complex exit reason referring to a literal that concurrently was removed, or when a terminating process continued executing a dirty NIF accessing a literal (via the heap) that concurrently was removed. * erts: Fix bug causing VM crash due to memory corruption of distribution entry. Probability of crash increases if Erlang distribution is frequently disconnected and reestablished towards same node names. Bug exists since OTP-21.0. * erts: Fixed bug causing crash of VM built with configuration --enable--sharing-preserving. Provoked when a sent message contains both a bit string and the heap binary (< 65 bytes) which the bit string was matched from. Bug exists since OTP-19.0 but has seen to be easier to provoke since OTP-22.1. - Changes for 22.1.6 * http://erlang.org/download/OTP-22.1.6.README * compiler, erts: The compiler could do an unsafe optimization of receives, which would cause a receive to only scan part of the message queue. * crypto: The AEAD tag was not previously checked on decrypt with chacha20_poly1305 * erts:Fix bug where the receive marker used by the runtime to do the receive queue optimization could be incorrectly set. The symptom of this would be that a message that should match in a receive never matches. * snmp: Agent discovery cleanup. If there is no receiver of INFORM then #state.reqs in snmpa_net_if keeps on growing for DISCOVERY.

# 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 ```
