The auth.unix.ip and auth.unix.gid caches live in the sunrpc module, so they cannot use the nfsd generic netlink family. Create a new "sunrpc" generic netlink family with its own "exportd" multicast group to support cache upcall notifications for sunrpc-resident caches. Define a YAML spec (sunrpc_cache.yaml) with a cache-type enum (ip_map, unix_gid), a cache-notify multicast event, and the corresponding uapi header. Implement sunrpc_cache_notify() in cache.c, which checks for listeners on the exportd multicast group, builds and sends a SUNRPC_CMD_CACHE_NOTIFY message with the cache-type attribute. Register/unregister the sunrpc_nl_family in init_sunrpc() and cleanup_sunrpc(). Signed-off-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |
