[PATCH] knfsd: Fix some minor sign problems in nfsd/xdr
There are a couple of tests which could possibly be confused by extremely large numbers appearing in 'xdr' packets. I think the closest to an exploit you could get would be writing random data from a free page into a file - i.e. leak data out of kernel space. I'm fairly sure they cannot be used for remote compromise. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
