Hi Namjae,
ΕΛΕΝΗ reported that ksmbd binds to the IPV6 wildcard (::) by default for ipv4 and ipv6 binding. So IPV4 connections are successful only when the Linux system parameter bindv6only is set to 0 [default value]. If this parameter is set to 1, then the ipv6 wildcard only represents any IPV6 address. Samba creates different sockets for ipv4 and ipv6 by default. This patch off sk_ipv6only to support IPV4/IPV6 connections without creating two sockets.
I think having two sockets '::' and '0.0.0.0' would be better, would that also be possible? It makes it more explicit and avoids ipv4 mapped addresses like ::ffff:192.0.2.128, which are really ugly. metze
