Subject: nfs-server: Freebsd client can't write to linux nfs [patch]

Date: Wed, 28 Oct 1998 00:46:01 -0500

Package: nfs-server
Version: 2.2beta37-2

Freebsd is not able to write to nfs-server 2.2beta37.  If you try, you
will get 0 length files.  Patch from Olaf below.  I applied it and now
things are working again from Freebsd.  Just passing this info on...

Hi steve

Oha! That's the check in nfsd.c I added to get a grip on the sudden NFS
death syndrome. Seems it did more harm than good...

Edit nfsd.c around line 490, and change the following:

        /* Check args. I've seen one client send a length of -1 */
-       count = argp->totalcount;
-       if (count > NFS_MAXDATA || count > argp->data.data_len) {
+	if (argp->data.data_len > NFS_MAXDATA) {
                Dprintf(L_NOTICE,
-                       "strange write req from %s: len %lu",
-                       nfsclient->clnt_name, argp->data.data_len);
+                       "strange write req from %s: len %lu",
+                       nfsclient->clnt_name, argp->data.data_len);
                return NFSERR_IO;
        }

Cheers
Olaf
