[SFTP] Read from write-only file not returning error
...am investigating a data-loss bug in SSHFS (https://github.com/libfuse/sshfs/issues/72). While the root cause is in SSHFS and has already been fixed, there seems to be some unfortunate interaction with what I believe is an OpenSSH bug: As far as I can tell, when sending a SSH_FXP_OPEN request with SSH_FXF_WRITE (i.e., opening the file write only), and then following up with a SSH_FXP_READ, the server responds with a SSH_FXP_STATUS indicating that all data has been read. Shouldn't the server signal some kind of error instead? Or am I making a mistake in parsing the response? Thanks, -Nikolaus -- GP...
