knfsd: 64 bit ino support for NFS server

2007-10-09T22:31:57+00:00

Modify the NFS server code to support 64 bit ino's, as
appropriate for the system and the NFS protocol version.

The gist of the changes is to query the underlying file system
for attributes and not just to use the cached attributes in the
inode.  For this specific purpose, the inode only contains an
ino field which unsigned long, which is large enough on 64 bit
platforms, but is not large enough on 32 bit platforms.

I haven't been able to find any reason why ->getattr can't be called
while i_mutex.  The specification indicates that i_mutex is not
required to be held in order to invoke ->getattr, but it doesn't say
that i_mutex can't be held while invoking ->getattr.

I also haven't come to any conclusions regarding the value of
lease_get_mtime() and whether it should or should not be invoked
by fill_post_wcc() too.  I chose not to change this because I
thought that it was safer to leave well enough alone.  If we
decide to make a change, it can be done separately.

knfsd: move nfsv4 slab creation/destruction to module init/exit

2007-10-09T22:31:56+00:00

We have some slabs that the nfs4 server uses to store state objects.
We're currently creating and destroying those slabs whenever the server
is brought up or down.  That seems excessive; may as well just do that
in module initialization and exit.

Also add some minor header cleanup.  (Thanks to Andrew Morton for that
and a compile fix.)

knfsd: clean up EX_RDONLY

2007-07-19T17:04:52+00:00

Share a little common code, reverse the arguments for consistency, drop the
unnecessary "inline", and lowercase the name.

knfsd: move EX_RDONLY out of header

2007-07-19T17:04:52+00:00

EX_RDONLY is only called in one place; just put it there.

knfsd: nfsd: enforce per-flavor id squashing

2007-07-17T17:23:08+00:00

Allow root squashing to vary per-pseudoflavor, so that you can (for example)
allow root access only when sufficiently strong security is in use.

knfsd: nfsd4: make readonly access depend on pseudoflavor

2007-07-17T17:23:08+00:00

Allow readonly access to vary depending on the pseudoflavor, using the flag
passed with each pseudoflavor in the export downcall.  The rest of the flags
are ignored for now, though some day we might also allow id squashing to vary
based on the flavor.

knfsd: nfsd4: return nfserr_wrongsec

2007-07-17T17:23:08+00:00

Make the first actual use of the secinfo information by using it to return
nfserr_wrongsec when an export is found that doesn't allow the flavor used on
this request.

knfsd: nfsd: provide export lookup wrappers which take a svc_rqst

2007-07-17T17:23:07+00:00

Split the callers of exp_get_by_name(), exp_find(), and exp_parent() into
those that are processing requests and those that are doing other stuff (like
looking up filehandles for mountd).

No change in behavior, just a (fairly pointless, on its own) cleanup.

(Note this has the effect of making nfsd_cross_mnt() pass rqstp->rq_client
instead of exp->ex_client into exp_find_by_name().  However, the two should
have the same value at this point.)
