494e177ada A new version of NetFlow node.
The most significant changes are:
- Use UMA zone instead of own chunk of memory.
- Lock each hash entry separately.
- Expire items "actively" - interrupt method can expire flows
  from hash slot, when it searches through it.
- Remove global tailqueue. Make callout thread search through
  every hash slot.
- Export datagram is detached from private data and filled. If
  it is incomplete, it is attached back. Another thread will
  continue working with it.

Lesser, but also important speedups:
- Flows in hash slot are stored in tailqueue. Whenever a flow is
  hit, it is moved to the begging, so it can be located quicker.
- When callout thread works with hash slot it bails out if
  slot mutex is contested.

d8f5d037f8 Major overhaul and cleanup of ng_source node.
Functional changes:
- Cut struct source_hookinfo. Just use hook_p pointer.
- Remove "start_now" command. "start" command now requires number of
  packets to send as argument. "start" command actually starts sending.
  Move the code that actually starts sending from ng_source_rcvmsg()
  to ng_source_start().
- Remove check for NG_SOURCE_ACTIVE in ng_source_stop(). We can be called
  with flag cleared (see begin of ng_source_intr()).
- If NG_SEND_DATA_ONLY() use log(LOG_DEBUG) instead of printf(). Otherwise
  we will *flood* console.
- Add ng_connect_t method, which sends NGM_ETHER_GET_IFNAME command
  to "output" hook. Cut ng_source_request_output_ifp(). Refactor
  ng_source_store_output_ifp() to use ifunit() and don't muck through
  interface list.
- Add "setiface" command, which gives ability to configure interface
  in case when ng_source_connect() failed. This happens, when we are not
  connected directly to ng_ether(4) node.
- Remove KASSERTs, which can never fire.
- Don't check for M_PKTHDR in rcvdata method. netgraph(4) does this
  for us.

Style:
- Assign sc_p = NG_NODE_PRIVATE(node) in declaration, to be
  consistent with style of other nodes.
- Sort variables.
- u_intXX -> uintXX.
- Dots at ends of comments.

0daccb9c94 In the current world order, solisten() implements the state transition of
a socket from a regular socket to a listening socket able to accept new
connections.  As part of this state transition, solisten() calls into the
protocol to update protocol-layer state.  There were several bugs in this
implementation that could result in a race wherein a TCP SYN received
in the interval between the protocol state transition and the shortly
following socket layer transition would result in a panic in the TCP code,
as the socket would be in the TCPS_LISTEN state, but the socket would not
have the SO_ACCEPTCONN flag set.

This change does the following:

- Pushes the socket state transition from the socket layer solisten() to
  to socket "library" routines called from the protocol.  This permits
  the socket routines to be called while holding the protocol mutexes,
  preventing a race exposing the incomplete socket state transition to TCP
  after the TCP state transition has completed.  The check for a socket
  layer state transition is performed by solisten_proto_check(), and the
  actual transition is performed by solisten_proto().

- Holds the socket lock for the duration of the socket state test and set,
  and over the protocol layer state transition, which is now possible as
  the socket lock is acquired by the protocol layer, rather than vice
  versa.  This prevents additional state related races in the socket
  layer.

This permits the dual transition of socket layer and protocol layer state
to occur while holding locks for both layers, making the two changes
atomic with respect to one another.  Similar changes are likely require
elsewhere in the socket/protocol code.

a definite setup was broken: two ng_ksockets are connected to each other,

interfaces. In this case one ng_ksocket is fooled with tag from the other
one.

Put node id into tag. In rcvdata method utilize tag only if it has our

195cf61776 In revision 1.29 timeout() was converted to ng_callout().
The difference is that the callout function installed via the
ng_callout() method is guaranteed to NOT fire after the shutdown
method was run (when a node is marked NGF_INVALID).  Also, the
shutdown method and the callout function are guaranteed to NOT
run at the same time, as both require the writer lock.  Thus
we can safely ignore a zero return value from ng_uncallout()
(callout_stop()) in shutdown methods, and go on with freeing
the node.

The said revision broke the node shutdown -- ng_bridge_timeout()
is no longer fired after ng_bridge_shutdown() was run, resulting
in a memory leak, dead nodes, and inability to unload the module.
Fix this by cancelling the callout on shutdown, and moving part
responsible for freeing a node resources from ng_bridge_timer()
to ng_bridge_shutdown().
