Re: [Fwd: [ANNOUNCE] Layer-7 Filter for Linux QoS]

Hi,

The concept could be improved in my opinion.
_All_ filters could use the regex (finally cnews regex in the kernel,
yiiha). So what we need is this to be an extension to _all_ filters.
i.e define u32 filter then a regexp on a match with a start offset to
start scanning etc. I think we need to have extended matches in general
regardless of this. I have been thinking of it for sometime and even
implemented some simple prototype (u32 followed by a fwmark). This is one
of the nice concepts netfilter introduced in my opinion.

BTW, i am not sure how efficient the stuff that Henry spencer
wrote is in comparison to newer research on variants of boyer-moore
for regex searches. comment?

The code also does seem inefficient but thats beside the point at the
moment (ex you seem to malloc for every incoming packet so you can do a
regex).

cheers,
jamal
