Summary: 0004367: Sshd version OpenSSH_5.4p1 refuses to start on SPARC Solaris 10 zone
Description: Today I installed lots of packages from current repository to a new Solaris 10 zone. One of the packages was CSWossh. Version OpenSSH_5.4p1, OpenSSL 0.9.8m 25 Feb 2010 outputs error message "derelativise_path: getcwd: Invalid argument" and refuses to start.

Previous version, OpenSSH_5.3p1, OpenSSL 0.9.8l 5 Nov 2009, which I installed about a week ago runs without any problems.

I was able to track the cause to this issue. After uncommenting a following line from sshd_config sshd refuses to start.

#AuthorizedKeysFile .ssh/authorized_keys

So the line should be left in comments. This is a little bit strange thing because above value should be default even if it's commented.

I think the AuthorizedKeysFileis a side effect of the real problem.

The new function derelativise_path() in servconf.c calls getcwd(NULL,0) and using zero for the size argument is unsupported on Solaris. This usage is supported in the GNU libraries though.

Thanks for the diagnosis.

You will find fixed package in my experimental repository:
https://bugzilla.mindrot.org/show_bug.cgi?id=1739 [^]

There is a little bug remaining, .ssh/authorized_keys doesn't work as expected. You should replace it with %h/.ssh/authorized_keys to have the original behavior.

mirch I saw you opened a bug upstream [1], I will post the patch and discuss the issue there.
