Errata 20170307¶

Topic: Implicit usage of IPV6_V6ONLY option
Category: Irccd
Corrected: 2.1.1 (or revision r430)
Affected versions: 2.1.0
Task: #640

Background¶

Transports allow communication between irccd and irccdctl over IP.

Problem¶

Some systems may disable or enable IPv4 fallback by default when using IPv6 sockets. The current code was testing if IPv4 was requested as a fallback, instead it must explicitly disable or enable the IPV6_V6ONLY option even if IPv4 is not requested.

Solution¶

Upgrade to a newer version if applicable or apply one of the following fixes:

Using Mercurial¶

If you don't have a local copy:

hg clone -u release-2.1 http://hg.malikania.fr/irccd

If you already have a local copy:

cd /path/to/irccd
hg pull
hg up release-2.1

And install new version of irccd.

Using patch¶
