However, rpcinfo is not part of iproute2 and it's an implicit dependency for ss. This series uses libtirpc[1] API to implement the same feature of rpcinfo for ss. This makes it possible to get info about rpc sockets, provided ss is compiled with libtirpc support. As a nice byproduct, this makes ss provide info about some ipv6 rpc sockets that are not displayed using 'rpcinfo -p'. - patch 1 adds a configure function to check for libtirpc; - patch 2 actually rework ss to use libtirpc.
