[patch] Memory leak from namei_zone in an error path in nfsrv_rename
Description:
------------
Memory leak in nfsrv_rename: In nfsrv_rename, every time a VOP_RENAME
operation fails FreeBSD leaks 2 items from the namei_zone which is equal
to 2K of kernel memory.
Filing this as a security issue because a FreeBSD NFS server (versions
4.6.2 to 6.1) can be compromised by exhausting kernel memory if a user
touches this error path many times.
I have tried a simple test case against Freebsd nfs server versions
4.6.2,...
