| H A D | nfs4xdr.c | cd93710e Fri Mar 02 16:14:31 CST 2012 Chuck Lever <chuck.lever@oracle.com> NFS: Fix nfs4_verifier memory alignment
Clean up due to code review.
The nfs4_verifier's data field is not guaranteed to be u32-aligned.
Casting an array of chars to a u32 * is considered generally
hazardous.
Fix this by using a __be32 array to generate a verifier's contents,
and then byte-copy the contents into the verifier field. The contents
of a verifier, for all intents and purposes, are opaque bytes. Only
local code that generates a verifier need know the actual content and
format. Everyone else compares the full byte array for exact
equality.
Also, sizeof(nfs4_verifer) is the size of the in-core verifier data
structure, but NFS4_VERIFIER_SIZE is the number of octets in an XDR'd
verifier. The two are not interchangeable, even if they happen to
have the same value.
