ons'>-0/+6 This patch implements the check generation id as provided by nfnetlink. This allows us to reject ruleset updates against stale baseline, so userspace can retry update with a fresh ruleset cache. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> 2017-02-12netfilter: nfnetlink: allow to check for generation IDPablo Neira Ayuso1-4/+27 This patch allows userspace to specify the generation ID that has been used to build an incremental batch update. If userspace specifies the generation ID in the batch message as attribute, then nfnetlink compares it to the current generation ID so you make sure that you work against the right baseline. Otherwise, bail out with ERESTART so userspace knows that its changeset is stale and needs to respin. Userspace can do this transparently at the cost of taking slightly more time to refresh caches and rework the changeset. This check is optional, if there is no NFNL_BATCH_GENID attribute in the batch begin message, then no check is performed.

And remove code that checks for its return value.

Four qdisc chose to call their own ops->destroy(), assuming their caller would not. This patch makes sure qdisc_create() calls ops->destroy() and fixes the four qdisc to avoid double free.
