Modified files: (Branch: RELENG_6) sys/kern uipc_usrreq.c Log: MFC: Close a race between enumerating UNIX domain socket pcb structures via sysctl and socket teardown. Note that we engage in a bit of trickery to preserve the ABI of 'struct unpcb' in 6.x. We change the UMA zone to hold a 'struct unpcb_wrapper' which holds a 6.x 'struct unpcb' followed by the new reference count needed for handling the race. We then cast 'struct unpcb' pointers to 'struct unpcb_wrapper' pointers when we need to access the reference count.
