From 34132e54cbd221d17d373fc54f4e3f7b85727f7f Mon Sep 17 00:00:00 2001 From: Damien Miller Date: Fri, 14 Jan 2000 15:45:46 +1100 Subject: - 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 - 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 --- bsd-bindresvport.c | 116 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 116 insertions(+) create mode 100644 bsd-bindresvport.c (limited to 'bsd-bindresvport.c') diff --git a/bsd-bindresvport.c b/bsd-bindresvport.c new file mode 100644 index 000000000..3ea37ee52 --- /dev/null +++ b/bsd-bindresvport.c @@ -0,0 +1,116 @@ +/* + * Sun RPC is a product of Sun Microsystems, Inc. and is provided for + * unrestricted use provided that this legend is included on all tape + * media and as a part of the software program in whole or part.
