Hi, I have attached a patch which allows to do flow classifications in userland (e.g based on url categories, LDAP users) and do bandwidth control in kernel(dummynet).
The patch has a) a setsocketopt, to associate a pipe to the socket. b) an ipfw option(sockarg) to redirect flows to corresponding pipe. Moreover, a member uint32_t is added to struct socket to hold the pipe info. I guess this structure is not part of kernel userland ABI. Please let me know your comments, which I would be glad to incorporate Thanks, Joe.
