FreeBSD -- NFS client data corruption and kernel memory disclosure

Problem Description: In FreeBSD 13.2 and 14.0, the NFS client was optimized to improve the performance of IOAPPEND writes, that is, writes which add data to the end of a file and so extend its size. This uncovered an old bug in some routines which copy userspace data into the kernel. The bug also...
