The spec requires that the access and deny bits requested in open_downgrade
represent the union of the bits for some subset of the OPENS for the given
open_owner and file.  Enforce that requirement.

Implement the nfsv4 RELEASE_LOCKOWNER operation.

From: NeilBrown <neilb@cse.unsw.edu.au>

fh_dup2 duplicates an entire svc_fh structure, so in addition to dget()'ing
the dentry, it also needs to bump the reference count on fh_export.

Moved it out of the header file into nfsfh.c for the simple reason that I
couldn't figure out how to reorganize the headers files right so that the
fh_dup2 could use the definition of svc_fh.  Since fh_dup2 is never actually
used outside of nfs4proc.c, it could just as well be moved there....

add the bookeeping necessary to remove all locks held by an nfsv4 lockowner
upon CLOSE, or upon state expiration.  calls locks_remove_posix().

replace list_del_init() with list_del on nfsv4 state structures that are
being reaped.

unlike v2/v3, nfsv4 returns nfserr_exist in some situations where the
underlying filesystem returns nfserr_isdir, nfserr_notdir.

on rename, nfsv4 returns nfserr_notdir instead of nfserr_symlink.

check lock length, return appropriate error

From: NeilBrown <neilb@cse.unsw.edu.au>

unlike v2/v3, nfsv4 returns nfserr_inval when attempting to read, write,
commit or test lock a symlink.  nfsv4 does return nfserr_symlink on lookup
and open, so a simple fix in fh_verify() will not work.

[PATCH] kNFSd: When looking for a shareowner in the nfsd open, make sure we don't get a lockowner instead.

From: NeilBrown <neilb@cse.unsw.edu.au>

When looking for a shareowner in the nfsd open, make sure we don't get a
lockowner instead.

[PATCH] kNFSd: Use only the uid when deciding whether a setclientid is being done with the "same principal".

From: NeilBrown <neilb@cse.unsw.edu.au>

I would have assumed that we should also check for the same security
(pseudo)flavor, but that doesn't seem to be how Solaris does it, and since
the spec doesn't suggest including such information in the clientid, that
would make it impossible to switch pseudoflavors.

From: NeilBrown <neilb@cse.unsw.edu.au>

Since the open op changes the current filehandle, we can't correctly replay
compounds containing opens unless we save the filehandle resulting from the
open as well as the encoded reply.

Use higher-resolution time for the changeinfo, instead of using time and
filesize.

From: NeilBrown <neilb@cse.unsw.edu.au>

Exclusive creates were failing with permission errors, because they don't set
the mode on the newly created file, and the permission check in fh_verify
(called at the end of do_open_lookup) was failing.  So pass in the
MAY_OWNER_OVERRIDE flag to allow the owner of the file to override the
permission check.

From: NeilBrown <neilb@cse.unsw.edu.au>

It's OK for the find_lockstateowner_str to fail; that just means we haven't
seen the lockowner, and will compare the request range to all locks on the
file.

Compare inode pointers instead of dentry pointers when checking an inode
refered to by a stateid against an inode refered to by a file handle.

Set st_vfs_set to 0 if the stateid/file handle check fails to avoid

Doesn't actually add integrity support on the server yet; just adapts
server-side code to the gss api changes necessary to get integrity working on
the client.

From: "J. Bruce Fields" <bfields@fieldses.org>

Note that the user (or exportfs, on the user's behalf) allows a gss
pseudoflavor to be used to access an export by exporting to a special client
named "gss/pseudoflavor-name", e.g., "gss/krb5" or "gss/lipkey-i".

ppc64 uses its own range allocator for ioremap (in order to allocate
things in a different space than normal vmalloc).  This is historic stuff,
we may get rid of it, but in the meantime, here's a patch turning the
spinlock in there into a semaphore so it doesn't blow up when doing
kmallocs.

Use the new kallsyms_lookup_name() in xmon on ppc64.  Ben said he might
backport these changes to ppc32 as well.

From: Rusty Russell <rusty@au1.ibm.com>

Attached patch adds a kallsyms_lookupname() function for lookups of a
symbol name to an address.  Debuggers such as ppc[64] xmon can use this.

It's intentionally not exported as a symbol for module use, since it
can be used to circumvent other symbol export restrictions.
