Description Eugene Teo (Security Response) 2009-04-04 01:13:20 UTC 
Description of problem:
The NFS file name limit is not being initialised correctly in the struct nfs_server. Make sure that we limit whatever is being set in nfs_probe_fsinfo() and nfs_init_server().

Also ensure that readdirplus and nfs4_path_walk respect our file name limits.
