Erlang/OTP 21.3.8.23

The erl_interface-3.11.3.2 application can be applied independently of other applications on a full OTP 21 installation.

Fix bug where sending of large data with ei_send_*/ei_rpc with infinite timeout could fail when the tcp buffer becomes full.

Fault has existed since OTP-21.

The ei API for decoding/encoding terms is not fully 64-bit compatible since terms that have a representation on the external term format larger than 2 GB cannot be handled.

Note! The erts-10.3.5.18 application *cannot* be applied independently of other applications on an arbitrary OTP 21 installation. On a full OTP 21 installation, also the following runtime dependencies have to be satisfied: -- kernel-6.1 (first satisfied in OTP 21.1) -- sasl-3.3 (first satisfied in OTP 21.2)

The following signals could pass before other signals from the same sender to the same receiver. That is, these signals could arrive too early.

-- garbage-collect request. Sent from one process to another using one of the garbage_collect() BIFs.

-- check-process-code request. Sent from one process to another using one of the check_process_code() BIFs.

-- is-process-alive reply. Sent as a response to a process calling the is_process_alive() BIF.

-- process-info reply. Sent as a response to a process calling one of the process_info() BIFs.

-- port-command reply. Sent as a response to a process calling one of the port_command() BIFs.

-- port-connect reply. Sent as a response to a process calling the port_connect() BIF.

-- port-close reply. Sent as a response to a process calling the port_close() BIF.

-- port-control reply. Sent as a response to a process calling the port_control() BIF.

-- port-call reply. Sent as a response to a process calling the port_call() BIF.

-- port-info reply. Sent as a response to a process calling one of the port_info() BIFs.

OTP-17307

Application(s):

erts

A garbage collection of a literal area missed messages that entirely consisted of a term in a literal area. This could in turn lead to a crash of the runtime system.

OTP-17349

Application(s):

erts

A call to process_flag(message_queue_data, off_heap) could cause a crash of the runtime system when sequential tracing was enabled.

The function dbg:n/1 used a local fun to set up a tracer on a remote node. This works fine as long as the remote node is running exactly the same version of Erlang/OTP but does not work at all otherwise. This is fixed by exporting the relevant function and by calling this function on the remote node to set up remote tracing.
