* In the splnet(9) times netgraph(4) was synchronous and if a messageglebius2006-01-121-18/+32
| | | | | | | | | | | | | | | | | | had been replied, the reply was always delivered to the originator synchronously. With introduction of netgraph item callbacks and a wait channel with mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning earlier than the command has been proceeded by target node. But still ngctl(8) can return prior to the reply has arrived to its node. To fix this: - Introduce a new flag for netgraph(4) messages - NGM_HASREPLY. This flag is or'ed with message like NGM_READONLY. - In netgraph userland library if we have sent a message with NGM_HASREPLY flag, then select(2) until reply comes. - Mark appropriate generic commands with NGM_HASREPLY flag, gathering them into one enum {}. Bump generic cookie.

* Implement direct support for semipersistant nodes.julian2001-01-301-2/+1
| | | | | | | | | | | | | (e.g. ethernet nodes are persistent until you rip out the hardware) Use this support in the ethernet and sample nodes. Add some more abstraction on the 'item's so that node and hook reference counting can be checked easier. Slight man page correction. Make pppoe type dependent on ethernet type. Clean up node shutdown a little. Move a mutex from MTX_SPIN to MTX_DEF (oops) Fix small ref-counting bug. remove warning on one2many type.
* Rewrite of netgraph to start getting ready for SMP.julian2001-01-061-22/+25
| | | | | | | | This version is functional and is aproaching solid.. notice I said APROACHING. There are many node types I cannot test I have tested: echo hole ppp socket vjc iface tee bpf async tty The rest compile and "Look" right. More changes to follow. DEBUGGING is enabled in this code to help if people have problems.

Also fix modules that don;t handle the fact that a caller may not supply a return message pointer. (benign at the moment because the calling code checks, but that will change)

| | | | | | | | | | | | | This clears out my outstanding netgraph changes. There is a netgraph change of design in the offing and this is to some extent a superset of soem of the new functionality and some of the old functionality that may be removed. This code works as before, but allows some new features that I want to work with and evaluate. It is the basis for a version of netgraph with integral locking for SMP use. This is running on my test machine with no new problems :-)

* Add two new generic control messages, NGM_ASCII2BINARY andarchie1999-11-301-20/+139
| | | | | | | | | | | | | | | | | | | | | | | NGM_BINARY2ASCII, which convert control messages to ASCII and back. This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes. Reviewed by: julian
