4.186. telnet

Prior to this update, the telnet.spec file used the "%{dist}" macro instead of the "%{?dist}", which violated packaging guidelines. This update replaces the macro with the correct one.

Prior to this update, the telnet utility used the sockaddr structure as storage for IPv6 addresses. As a consequence, telnet could emit incomplete IPv6 addresses because the sockaddr structure is to small to hold an IPv6 address. This update modifies telnet to use the sockaddr_storage structure as IPv6 address storage and now emits complete IPv6 addresses.

Prior to this update, the telnet utility could enter an infinite loop when the user specified the "-b" parameter with a non-existing network interface. This update modifies the telnet command to print errors when users specify a non-existing network interface.

Prior to this update, the in.telnetd daemon could fail to update information in the /var/run/utmp directory when a deadlock occured in a telnet session. This update modifies telnetd to update /var/run/utmp correctly.
