Same listener is used for both sshd and sftpd. Previously

112

the sftpd server had to be run on a separate port, now

113

the sshd listener will start an sftpd server when an sftp

114

client connects.</p>

The sftp-server could crash if a "ls" was done on the

154

client, and a file was removed while ssh_sftpd:list_dir

155

was reading the directory, an error code from

156

read_file_info wasn't handled properly. This fix makes ls

157

return an error code instead.</p>
