darrenr eda7e8d3e3 back out previous change - these diffs aren't what I'd tested. 2004-05-29 14:18:33 +00:00
darrenr 15f2ef8f2c add mmap(2) interface to bpf(4) devices, along with BIOCMMAPINFO ioctl call
for applications to interact with the bpf device for the purpose of using
mmap to examinen captured data.

darrenr 4800529c7e Add a count of the number of packets that match the bpf filter applied to a
particule device.  In doing this, make a new the bpf_stat structure with
members that are u_long rather than u_int, matching the counters in the bpf_d.
the original bpf_stat is now bpf_stat_old and so to the original ioctl
is preserved as BIOCGSTATSOLD.

darrenr eee3190c06 Fix bpf so that select will return for a timeout (from FreeBSD.)
Fix the behaviour of BIOCIMMEDIATE (fix from LBL BPF code via FreeBSD.)

In bpf_mtap(), optimise the calling of bpf_filter() and catchpacket()
based on whether or not the entire packet is in one mbuf (based on
similar change FreeBSD but fixes BIOC*SEESENT issue with that.)

Copy the implementation of BIOCSSEESENT, BIOCGSEESENT by FreeBSD.

thorpej 27dba7b8e8 Implement two new BPF ioctls: BPFGHDRCMPLT and BPFSHDRCMPLT, to get/set
the "header already complete" flag.  This allows BPF writers to spoof
layer 2 source addresses (providing the layer 2 in use supports it) in
applications where this is necessary.  From Greg Smith <greg@nas.nasa.gov>.
