* Rewrite of netgraph to start getting ready for SMP.julian2001-01-061-50/+66
| | | | | | | | 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 :-)

| | | | | This fixes a bug where if the original packet was modified downstream of the tee node, then the copy could get modified too.
* Add two new generic control messages, NGM_ASCII2BINARY andarchie1999-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | 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
