Hi ,
I have been looking at the SAMBA VFS layer, and I have a request
for a function to be added to the interface.
I would like to propose an ioctl like function where file system defined
parameters can be passed back and forth between SAMBA and physical
file-system.
This will be useful in cases where the file system supports some
features over and above ordinary Unix file systems. For example,
Creation Time, if we have an ioctl call we can use that to set and get
creation time on files with minimum modification to samba.
The right thing is to support all the features an NTFS support.
We are already planning to radically change the interface to be more
flexible and, above all to make the ntfs-posix translation a module so
that it can be replaced for richer or different then posix file systems.
I propose something of the form
int
vfs_ioctl( struct connection_struct * conn, struct files_struct * fsp,
...);
or something like
int
vfs_ioctl ( struct connection_struct * conn, struct files_struct * fsp,
ulong cmd, void * inbuf,size_t in_size, void* outbuf, size_t out_size).
of course I realize the nightmare of maintaining an IOCTL list, but I am
hoping in the case of SAMBA it would not be as bad as something like an
OS, and this feature will be used to add extensions to SAMBA so that
the capabilities of underlying file systems can be reflected more
accurately in SAMBA.
I'm not sure this is a good idea.
How would you like to use these ioctl then?
Simo.
