...ike to propose the following extensions to the SFTP protocol. - statvfs operation - atomic rename (just plain POSIX rename() without the existence check) These are the most requested features in SSHFS, which need support in sftp-server too. They could be added to the current protocol with the SSH_FXP_EXTENDED message type. Here's a patch implementing the statvfs operation. It looks like OpenBSD current doesn't have statvfs(), but it works on Linux, and should be pretty trivial to port to OBSD, although it would be even nicer to add a statvfs (defined by SUS) impementation. Comments are welcom...

This is needed to be able to support statfs operation on an SSH filesystem (http://fuse.sourceforge.net/sshfs.html). It uses and sends only those fields of struct statfs which are common with struct statvfs as defined by POSIX, and which are shared among most UNIX-like systems. The SSH_FXP_EXTENDED message type is used, so this change is backward compatible and conforms to the protocol specification. Please comment on whether this change is acceptable or what is needed for it's acceptance into the openssh tree. Thanks, Miklos Index: ssh/sftp-server.c ===================================...

I am using sshfs with FUSE to mount a remote directory over ssh/sftp (on linux). It would be nice if df could be able to show the total size/free space of the mounted directory. I am aware that returning size/free space would have some limitations. For example, if a subdir of the mounted directory has another filesystem mounted on the remote server, this can not be represented simply. However,
