hi all, I have a query regarding ioctl function. I am using openbsd 2.9 BIOCSETF option in ioctl function is used to set a new filter to the interface. It also does the action of BIOCFLUSH, in the sense that it flushes the packets in the buffer if any, right ? I need BIOCSETF 's action with out the 'flushing'. I looked at the code under case 'BIOCSETF'. In fact a function called bpf_reset_d(d) is called to flush the packet buffer. So i commented that out ie. do not call bpf_reset_d(). Will this serve my purpose of changing the bpf filter without flushing the packets already in the buffer. Any information on the sbuf,hbuf,fbuf would be great. thanks a lot ashley - This is the TCPDUMP workers list.
