Modified files:
sys/net : if.c
Log message:
Clear the internal table used by if_get(9) and sleep until all
remaining ifp references are released *without* the NET_LOCK().
It's safe to do so because the KERNEL_LOCK() serializes accesses
to ``if_map''.
More importantly this fix possible deadlocks between if_get() and
the NET_LOCK(). It is now possible to call them in whatever order.
ok visa@, dlg@
