Jakub Kicinski cff2d762cd genetlink: reject use of nlmsg_flags for new commands ... Commit 9c5d03d362 ("genetlink: start to validate reserved header bytes") introduced extra validation for genetlink headers. We had to gate it to only apply to new commands, to maintain bug-wards compatibility. Use this opportunity (before the new checks make it to Linus's tree) to add more conditions. Validate that Generic Netlink families do not use nlmsg_flags outside of the well-understood set.
