This patch breaks the NFS server on my heroically modern RH FC1 machine.
There's a mysterious 30-second pause when initscripts are bringing up
mountd.
showmount (from a FC5 client) works:
box:/usr/src/25> 0 showmount -e vmm
Export list for vmm:
/ *
/mnt/hda5 *
But things get really exciting when we try to mount it:
box:/usr/src/25> 0 mount vmm:/mnt/hda5 /mnt
*** buffer overflow detected ***: mount terminated

btw, knfsd-sunrpc-cache-remote-peers-address-in-svc_sock.patch breaks the build:
net/sunrpc/svcsock.c: In function 'svc_recvfrom':
net/sunrpc/svcsock.c:581: error: 'svsk' undeclared (first use in this function)
net/sunrpc/svcsock.c:581: error: (Each undeclared identifier is reported only once
but the next patch
(knfsd-sunrpc-dont-set-msg_name-and-msg_namelen-when-calling-sock_recvmsg.patch)
fixes that.
