net: sched: Add policy validation for tc attributes
A number of TC attributes are processed without proper validation (e.g., length checks). Add a tca policy for all input attributes and use when invoking nlmsg_parse. The 2 Fixes tags below cover the latest additions. The other attributes are a string (KIND), nested attribute (OPTIONS which does seem to have validation in most cases), for dumps only or a flag. Fixes: 5bc17018 ("net: sched: introduce multichain support for filters") Fixes: d47a6b0e ("net: sched: introduce ingress/egress block index attributes for qdisc") Signed-off-by:David Ahern <dsahern@gmail.com> Signed-off-by:
