this is the first public announcement of scannedonly.
Scannedonly is a samba VFS module that ensures that only files that have
been scanned for viruses are visible and accessible to the end user.
Scannedonly was developed because of scalability problems with
samba-vscan: high server loads when (the same) files were requested
often, and timeouts when large zip files were requested.
Scannedonly comes in two parts: a samba vfs module and (one or more)
daemons. The daemon scans files. If a certain file is clean, a second
file is created with prefix .scanned:. The samba module simply looks if
such a .scanned: file exists, and is newer than the pertinent file. If
this is the case, the file is shown to the user. If this is not the
case, the file is not returned in any directory listing, and cannot be
opened. The samba vfs module will also tell the daemon to scan this file.
