Package: gnats
Version: 4.1.0-0
Severity: important
Tags: patch
After installing gnats, I discovered that any attempts to connect to the
gnatsd resulted in two log file entries in syslog that look like this:
May 11 15:23:34 gaia gnatsd[13743]: connect from ::ffff:192.168.19.254
(::ffff:192.168.19.254)
May 11 15:23:34 gaia gnatsd[13743]: ?: bad address family 10
Upon looking up where this line came from, it appears to be because the
incoming socket is being treated as if it is AF_INET6 rather than
AF_INET, which is what gnatsd is expecting. I conclude that this is
happening on my system because it is set up with IPv6 addresses as well
as IPv4 addresses.
I have patched my local copy to accept connections with an address
family of AF_INET6 and to look the name up properly. If I can figure
out how to do it, I'll attach the patch.
