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.)

knfsd: nfsd4: simplify exp_pseudoroot arguments

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

We're passing three arguments to exp_pseudoroot, two of which are just fields
of the svc_rqst.  Soon we'll want to pass in a third field as well.  So let's
just give up and pass in the whole struct svc_rqst.

Also sneak in some minor style cleanups while we're at it.

knfsd: nfsd4: parse secinfo information in exports downcall

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

We add a list of pseudoflavors to each export downcall, which will be used
both as a list of security flavors allowed on that export, and (in the order
given) as the list of pseudoflavors to return on secinfo calls.

This patch parses the new downcall information and adds it to the export
structure, but doesn't use it for anything yet.

[PATCH] knfsd: add some new fsid types

2007-02-14T16:09:53+00:00

Add support for using a filesystem UUID to identify and export point in the
filehandle.

For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room.  For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.

When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.
