- Merged OpenBSD IPv6 patch:
- [sshd.c sshd.8 sshconnect.c ssh.h ssh.c servconf.h servconf.c scp.1]
[scp.c packet.h packet.c login.c log.c canohost.c channels.c]
[hostfile.c sshd_config]
ipv6 support: mostly gethostbyname->getaddrinfo/getnameinfo, new
features: sshd allows multiple ListenAddress and Port options. note
that libwrap is not IPv6-ready. (based on patches from
fujiwara@rcac.tdi.co.jp)
- [ssh.c canohost.c]
more hints (hints.ai_socktype=SOCK_STREAM) for getaddrinfo,
from itojun@
- [channels.c]
listen on _all_ interfaces for X11-Fwd (hints.ai_flags = AI_PASSIVE)
- [packet.h]
allow auth-kerberos for IPv4 only
- [scp.1 sshd.8 servconf.h scp.c]
document -4, -6, and 'ssh -L 2022/::1/22'
- [ssh.c]
'ssh @host' is illegal (null user name), from
karsten@gedankenpolizei.de
- [sshconnect.c]
better error message
- [sshd.c]
allow auth-kerberos for IPv4 only
- Big IPv6 merge:
- Cleanup overrun in sockaddr copying on RHL 6.1
- Replacements for getaddrinfo, getnameinfo, etc based on versions
from patch from KIKUCHI Takahiro <kick@kyoto.wide.ad.jp>
- Replacement for missing structures on systems that lack IPv6
- record_login needed to know about AF_INET6 addresses
- Borrowed more code from OpenBSD: rresvport_af and requisites
