sk_run_filter9
Run a filter on a socket
Arguments
skb
buffer to run the filter on
fentry
filter to apply
Overview
Decode and apply filter instructions to the skb->data. Return length to keep, 0 for none. skb is the data we are filtering, filter is the array of filter instructions. Because all jumps are guaranteed to be before last instruction, and last instruction guaranteed to be a RET, we dont need to check flen. (We used to pass to this function the length of filter)
