Useful stuff. There are things along these lines that i have been contemplating myself.
I think it would be valuable to specify a set of flags for filtering what gets sent to user space instead of unconditionally. Example, filter level 0: - what we have before your patch filter level 1: - protocol version - header size - maximum number of attributes filter level 2: - the rest of the stuff you have What netlink does today to filter at user space is something that can be avoided with the above (an improvement in my opinion if you have a lot of genl items in the kernel). cheers, jamal On Thu, 2006-31-08 at 23:21 +0200, Thomas Graf wrote: > Additionaly exports the following information when providing > the list of registered generic netlink families: > - protocol version > - header size > - maximum number of attributes > > - list of available operations including > - id > - flags > - avaiability of policy and doit/dumpit function > > libnl HEAD provides a utility to read this new information: > > 0x0010 nlctrl version 1 > hdrsize 0 maxattr 6 > op GETFAMILY (0x03) [POLICY,DOIT,DUMPIT] > 0x0011 NLBL_MGMT version 1 > hdrsize 0 maxattr 0 > op unknown (0x02) [DOIT] > op unknown (0x03) [DOIT] > .... > - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
