* legoscia/tls_dist_error_reporting:
Report bad options for outgoing TLS distribution
Save error reasons for TLS distribution connections
Report bad options for TLS distribution connections
OTP-13219

If ssl:connect/3 returns an error related to options, let's log that
so we have a chance to see it and fix it.

Test socket listen options for TLS distribution
Test port options for TLS distribution

* legoscia/tls_dist_nodelay:
Add test for dist_nodelay option
Honour dist_nodelay socket option in tls_dist proxy
OTP-13143
|
|
Add test that checks that the option inet_dist_listen_options is used
when starting a node with TLS distribution.
This test was adapted from inet_dist_options_options in
erl_distribution_SUITE.
|
|
The inet_dist_ options, such as min/max port numbers aren't used
with TLS distribution. This commits uses those settings in the
same way as they're used in inet_tcp_dist.erl
|
|
If ssl:ssl_accept/2 returns an error related to options, it's most
likely something we want to log. In particular, if the specified
certificate file doesn't exist, this is where the error ends up, so we
shouldn't just throw the error away.
|
|
The duplicate_name error returned from erl_epmd:register_node elicits a
particularly precise error message from net_kernel, so let's pass it
along to our caller.
Not doing this for the other things that could go wrong here, since for
those having the line number will likely aid debugging.

If a plaintext cluster has nodelay=1 then so should the tls cluster;
significant performance issues have been seen when nodelay isn't set
|
|
In some instances, restarting a node causes a fatal SSL error on
the other nodes which isn't handled leaving the socket open. Eventually
the nodes will net tick timeout but the node being restarted never
comes back to life
By handling the fatal error and closing the socket, the restarting
node can restart successfully even when the ssl error occurs

* pg/fix-ssl_tls_dist_proxy-setup-loop:
Fix setup loop of SSL TLS dist proxy
OTP-9915
OTP-9916
|
|
Fix a bug where the caller would timeout and ssl_tls_dist_proxy would
crash.
Fix a bug where a timeout from the SSL layer would block the
distribution forever (typically when a non-SSL node tries to connect to an
SSL node).
Add this very case as a test (test_server tries to connect to SSL nodes).
Run the proxy exclusively on the loopback interface.
|
|
The proxy socket or the SSL socket can be closed during the setup phase.
In such situations, the proxy processes must exit nicely, to avoid any
leak of processes waiting forever for data from closed sockets.

Also cleaned up old gaurds.
