| H A D | nfsnode.h | diff 176134 Sat Feb 09 18:13:19 MST 2008 attilio namei() can call underlying nfs_readlink() passing a struct uio pointer owned by a NULL owner. This will lead consequent VOP_ISLOCKED() present into nfs_upgrade_vnlock() to panic as it only acquire curthread now. Fix nfs_upgrade_vnlock() and nfs_downgrade_vnlock() in order to not use more the struct thread pointer passed as argument (as it is really nomore required there as vn_lock() and VOP_UNLOCK doesn't get the lock more). Using curthread, in place, doesn't get ambiguity as LK_EXCLOTHER should be handled as a "not locked" request by both functions. Reported by: kris Tested by: kris Reviewed by: ups |
