This patch adds some sysctls: kern.rpc.unenc.tx_msgcnt kern.rpc.unenc.tx_msgbytes kern.rpc.unenc.rx_msgcnt kern.rpc.unenc.rx_msgbytes kern.rpc.tls.tx_msgcnt kern.rpc.tls.tx_msgbytes kern.rpc.tls.rx_msgcnt kern.rpc.tls.rx_msgbytes kern.rpc.tls.handshake_success kern.rpc.tls.handshake_failed kern.rpc.tls.alerts which allow a NFS server sysadmin to determine how much NFS-over-TLS is being used. A large number of failed handshakes might also indicate an NFS confirguration problem. This patch moves the definition of "kern.rpc" from the kgssapi module to the krpc module. As such, both modules need to be rebuilt from sources. Since __FreeBSD_version was bumped yesterday, I will not bump it again. Suggested by: gwollman Discussed on: freebsd-current MFC after: 1 month
