v2.1.3

2.1.3-stable "Friedrichroda" : 17-Apr-2021:

As usual, every new release gets named after a nice travel location.
This time it is Friedrichroda, Germany.

FIXES:

• Do not exit on SIG_PIPE (broken pipe) *** security fix (DoS) ***.
  This would be exploitable easily by "echo | telnet hostname port"!
  This fix requires support for the send() flag MSG_NOSIGNAL. Seems
  to be present in *BSD and Linux (at least).
• Modified regex checks during POST command:
  • Prevent postings to Newsgroups: ,,,
  • Prevent sender '@'
  • Prevent \r\n\t in subjects
  • Unified structure of regex tests with macros
• Minor fix in documentation for ACL management.

ADDED FEATURES:

• Created the manpages wendzelnntpd(8) and wendzelnntpadm(8).
• The make target "install" now installs manpages, too.

MISC:

• Listen on ::1 per default, too (in addition to 127.0.0.1).
• Slackware build script does not require make install anymore,
  which makes the whole process much cleaner. Also, this is quicker.
• Added additional meta-data for https://slackbuilds.org compatibility (beta).
• Applied several adjustments and improvements from SBo's repository.
• Improved some comments in the code.
