openssh unix dev - Aug 2013 - sftp logging, filenames with strange characters and parsing the logfile

Hi!

The OpenSSH sshd sftp function can be configured to send logging to syslog.

When a file is open'ed or closed with unexpected characters, those
characters are send directly to syslog, e.g. a file with a '"' in
it:

Aug 21 17:09:11 test internal-sftp[10128]: open
"/usr/home/test/te"st" flags WRITE,CREATE,TRUNCATE mode 0664

This makes is difficult and error-prone to parse the logfile. Would it
be possible to mask those characters in filenames, e.g. like the quotemeta
function in perl does or the %xx escapes used in apache ?

Alternativly, if the logging is changed so that the filename comes at
the end, then the parser can just read until end-of-line (if the filename
does not contain a newline...)

Something like this:

Aug 21 17:09:11 test internal-sftp[10128]: open flags WRITE,CREATE,TRUNCATE mode
0664 name /usr/home/test/te"st
