ae2cb97e54 Fix build without BPF_JITTER option. 2005-12-07 21:41:45 +00:00
Jung-uk Kim
848c454cc1 Add BPF Just-In-Time compiler support for ng_bpf(4). 
The sysctl is changed from net.bpf.jitter.enable to net.bpf_jitter.enable
and this controls both bpf(4) and ng_bpf(4) now.

669bb973c4 Avoid calling bpf_filter() with len == 0, which causes a change in semantics 
(it treats the buffer pointer as an mbuf pointer) and subsequent panic.

f8aae7776f Switch to using C99 sparse initialisers for the type methods array. 
Should make no binary difference.

f0184ff8e3 Fix GCC warnings caused by initializing a zero length array. In the process, 
simply things a bit by getting rid of 'struct ng_parse_struct_info' which
was useless because it only contained one field.

30400f03aa Part 2 of the netgraph rewrite. 
This is mostly cosmetic changes, (though I caught a bug or two while
makeing them)

069154d55f Rewrite of netgraph to start getting ready for SMP. 
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.

589f6ed8ce Divorce the kernel binary ABI version number from the message 
format version number. (userland programs should not need to be
recompiled when the netgraph kernel internal ABI is changed.

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 :-)

a4ec03cfa8 Two simple changes to the kernel internal API for netgraph modules, 
to support future work in flow-control and 'packet reject/replace'
processing modes.

ab0d3c94db Change definition of NG_BPF_HOOKPROG_SIZE() so as not to require 
a structure pointer, just the number of BPF instructions.

apply bpf(4) filters to data travelling through a netgraph network.
