             Summary: Relative symbolic links with .. is not resolved properly by sftp readLink
                 Key: SSHD-730
                 URL: https://issues.apache.org/jira/browse/SSHD-730
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 1.3.0, 1.2.0, 1.1.0
            Reporter: Lukas Waldmann


Using sftp to resolve symbolic links doesn't return proper resolution in case symbolic link contains ..
Since version 1.1 the sendLink function of SftpSubsystem uses
normalizedPath = SelectorUtils.normalizePath(unixPath, "/");
to normalize path
This function however return invalid path in case link contains ".."
So for example if link is "../test/file" than normalizePath returns "test/file" which is invalid because in can not be resolved properly in the context of the current directory which symbolic link is referring to.
