Pull up following revision(s) (requested by bouyer in ticket #1644): sys/sys/socketvar.h: revision 1.126 sys/kern/init_main.c: revision 1.433 sys/kern/uipc_socket.c: revision 1.205 Fix kern/45093 as discussed on tech-kern@: http://mail-index.netbsd.org/tech-kern/2011/06/17/msg010734.html The cause of the problem is that the so_pendfree is processed with the softnet_lock held at one point, and processing the list calls sodoloanfree() which may kpause(). As the thread sleeps with softnet_lock held, it ultimately cause a deadlock (see the PR or tech-kern thread for details). Although it should be possible to call sodopendfree() after releasing the socket lock, it's not so easy to know where he socket lock is held and where it's not, so we may hit the issue again later. Add a kernel thread to handle the so_pendfree list, and wake up this thread when adding mbufs to this list. Get rid of the various sodopendfree() calls, hopefully fixing definitively the problem.
