Author: bz Date: Sat Aug 14 14:13:44 2010 New Revision: 211301 URL: http://svn.freebsd.org/changeset/base/211301 Log: In rip6_input(), in case of multicast, we might skip the normal processing and go to the next iteration early if multicast filtering would decide that this socket shall not receive the data. Unlock the pcb in that case or we leak the read lock and next time trying to get a write lock, would hang forever.
