There are ongoing disputes as to whether we want to switch to directly using
UMA flags M_WAITOK/M_NOWAIT for mbuf(9) allocation.
overhead of packet capture by allowing a user process to directly "loan"
buffer memory to the kernel rather than using read(2) to explicitly copy
data from kernel address space.
The user process will issue new BPF ioctls to set the shared memory
buffer mode and provide pointers to buffers and their size. The kernel
then wires and maps the pages into kernel address space using sf_buf(9),
which on supporting architectures will use the direct map region. The
current "buffered" access mode remains the default, and support for
zero-copy buffers must, for the time being, be explicitly enabled using
a sysctl for the kernel to accept requests to use it.
The kernel and user process synchronize use of the buffers with atomic
operations, avoiding the need for system calls under load; the user
process may use select()/poll()/kqueue() to manage blocking while
waiting for network data if the user process is able to consume data
faster than the kernel generates it. Patchs to libpcap are available
to allow libpcap applications to transparently take advantage of this
support. Detailed information on the new API may be found in bpf(4),
including specific atomic operations and memory barriers required to
synchronize buffer use safely.
These changes modify the base BPF implementation to (roughly) abstrac
the current buffer model, allowing the new shared memory model to be
added, and add new monitoring statistics for netstat to print. The
implementation, with the exception of some monitoring hanges that break
the netstat monitoring ABI for BPF, will be MFC'd.
Zerocopy bpf buffers are still considered experimental are disabled
by default. To experiment with this new facility, adjust the
net.bpf.zerocopy_enable sysctl variable to 1.
Changes to libpcap will be made available as a patch for the time being,
and further refinements to the implementation are expected.

to make ports CFLAGS more independent of src/'s CFLAGS WRT aliasing.
Discussed with: brooks
Change the default CFLAGS to match the simple defaults that the
tinderboxes use. By using -fno-strict-aliasing by default we are
choosing to ignore problems in code which had the potential to
shoot ourselves in the foot.
The kernel config file is KERNCONF=MPC85XX, so the usual procedure applies:
1. make buildworld TARGET_ARCH=powerpc
2. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX
This default config uses kernel-level FPU emulation. For the soft-float world
approach:
1. make buildworld TARGET_ARCH=powerpc TARGET_CPUTYPE=e500
2. disable FPU_EMU option in sys/powerpc/conf/MPC85XX
3. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

were recently), a simple 'make cleandepend; make depend' is sufficient
to keep the tree buildable after a cvs update when doing incremental
builds.
However, kdump and truss use a script which searches for header files
that define ioctls, and generates C code that includes them. This
script will usually not need updating when a header file is removed,
so the normal dependency mechanism will not realize that it needs to
be re-run. One is therefore left with code that references dead files
but will only be removed by a full 'make clean', which defeats the
purpose of incremental builds.
To work around this, modify the cleandepend target in bsd.dep.mk to
also remove any files listed in a new variable named CLEANDEPFILES,
and modify kdump's and truss's Makefiles accordingly.
