Bug#738619: Upper-case Host specification in .ssh/config doesn't work anymore in 6.5p1

[Didier Raboud <odyx@debian.org>]

Package: openssh-client
Version: 1:6.5p1-1
Severity: important
Tags: upstream

Hi Colin,

Since the 6.5p1 update, uppercase "Host" specifications in .ssh/config
"don't work" anymore:

I had the following in my .ssh/config that allowed me to correctly
connect with 6.4p1:

	Host Icterus
	        HostName odyx.homelinux.org

With 6.5p1, this fails as follows:
$ ssh -vvvv Icterus
OpenSSH_6.5, OpenSSL 1.0.1f 6 Jan 2014
debug1: Reading configuration data /home/didier/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *
ssh: Could not resolve hostname icterus: Name or service not known

While it worked with 6.4p1-2:
$ ssh -vvvv Icterus
OpenSSH_6.4, OpenSSL 1.0.1f 6 Jan 2014
debug1: Reading configuration data /home/didier/.ssh/config
debug1: /home/didier/.ssh/config line 1: Applying options for Icterus
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to odyx.homelinux.org

That's IMHO a regression, hence the "important" severity.

Cheers, 

OdyX
