Syslog UDP input does not set gl2_remote_ip in Graylog 3.0

[jplitza]

Expected Behavior

The gl2_remote_ip field gets populated with the source IP address for messages sent in via SyslogUDPInput.

Current Behavior

It doesn't. A pipeline containing

debug($message.gl2_remote_ip);

logs

INFO  [Function] PIPELINE DEBUG: Passed value is NULL.

Steps to Reproduce (for bugs)

1. Run Graylog 3.0.0-2.alpha.3 from the Ubuntu repository
2. Set up Syslog UDP input
3. Send in some messages

Context

Same problem as #3980, but for Syslog instead of GELF.

Your Environment

• Graylog Version: 3.0.0-alpha.3+7530b69, codename Space Moose
• Elasticsearch Version: 5.6.12
• MongoDB Version: 3.6.3-0ubuntu1
• Operating System: Ubuntu 18.04
• Browser version: Firefox 63.0

Actually, this doesn't only affect Syslog, but also GELF, and only occurs in Graylog 3.0.0. Downgradaing to 2.4 "solved" the problem.

@jplitza Thanks for the report. This is the same issue as in #5293 and will be fixed before the final 3.0 release.

@jplitza This will work again once #5293 is fixed. I am closing this issue, please check #5293 for updates. Thank you!
