| H A D | nfs_clstate.c | diff 231133 Tue Feb 07 16:39:12 MST 2012 rmacklem r228827 fixed a problem where copying of NFSv4 open credentials into a credential structure would corrupt it. This happened when the p argument was != NULL. However, I now realize that the copying of open credentials should only happen for p == NULL, since that indicates that it is a read-ahead or write-behind. This patch fixes this. After this commit, r228827 could be reverted, but I think the code is clearer and safer with the patch, so I am going to leave it in. Without this patch, it was possible that a NFSv4 VOP_SETATTR() could have changed the credentials of the caller. This would have happened if the process doing the VOP_SETATTR() did not have the file open, but some other process running as a different uid had the file open for writing at the same time.
