[ Upstream commit d48c8124749c9a5081fe68680f83605e272c984b ] When the passed token is longer than 4032 bytes, the remaining part of the token must be copied from the rqstp->rq_arg.pages. But the copy must make sure it happens in a consecutive way. With the existing code, the first memcpy copies 'length' bytes from argv->iobase, but since the header is in front, this never fills the whole first page of in_token->pages. The mecpy in the loop copies the following bytes, but starts writing at the next page of in_token->pages. This leaves the last bytes of page 0 unwritten. Symptoms were that users with many groups were not able to access NFS exports, when using Active Directory as the KDC.
