- Allocate scratch memory on stack instead of pre-allocating it with the filter as we do from bpf_filter()[1]. - Revert experimental use of contigmalloc(9)/contigfree(9). It has no performance benefit over malloc(9)/free(9)[2].

- Change internal function bpf_jit_compile() to return allocated size of the generated binary and remove page size limitation for userland. - Use contigmalloc(9)/contigfree(9) instead of malloc(9)/free(9) to make sure the generated binary aligns properly and make it physically contiguous.

- Make BPF JIT compiler working again in userland. We are limiting size of generated native binary to page size for now. - Update copyright date and fix some style nits.

Initialize scratch memory for JIT-compiled filter when it is allocated. Previously it may have contained unnecessary (even sensitive) data from the previous allocation. As a (good) side effect, scratch memory may be used to store the previous filter state(s) safely because it is allocated and freed with filter itself. However, use it carefully because bpf_filter(9) does not have this behavior.

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.

Add experimental BPF Just-In-Time compiler for amd64 and i386.
Use the following kernel configuration option to enable:
options BPF_JITTER
If you want to use bpf_filter() instead (e. g., debugging), do:
sysctl net.bpf.jitter.enable=0
to turn it off.
Currently BIOCSETWF and bpf_mtap2() are unsupported, and bpf_mtap() is partially supported because 1) no need, 2) avoid expensive m_copydata(9).
Obtained from: WinPcap 3.1 (for i386)
