Re: Re: [Snort-devel] Urgent (hopefully not dumb) question:resp:(onses) on which device?

[Martin Roesch <roesch () sourcefire com>]

Yeah, my bad.  I was attmepting to speed up the flexresp response time
by precaching the TCP response packets and only filling in needed fields
at "fire time" instead of creating the packet from scratch every time it
was needed.  While it was indeed faster, I forgot to finish up what I
was working on due to the increasing number of distractions I have in my
life (baby, company, snort, etc) and as a result the flexresp code in
1.8.2 was massively broken.  

Anyway, it's fixed in CVS and will be fixed when I officially release
1.8.3 later today.
