Subject: Re: [PATCH net v3] net/sched: cls_api: add missing validation of
 netlink attributes

> Similarly to what has been done in 8b4c3cdd9dd8 ("net: sched: Add policy
> validation for tc attributes"), fix classifier code to add validation of
> TCA_CHAIN and TCA_KIND netlink attributes.
> 
> tested with:
>  # ./tdc.py -c filter

> v2: Let sch_api and cls_api share nla_policy they have in common, thanks
>     to David Ahern.
> v3: Avoid EXPORT_SYMBOL(), as validation of those attributes is not done
>     by TC modules, thanks to Cong Wang.
>     While at it, restore the 'Delete / get qdisc' comment to its orginal
>     position, just above tc_get_qdisc() function prototype.
