This patch adds support for overloading stateful objects operations
through the select_ops() callback, just as it is implemented for
expressions.This change is needed for upcoming additions to the stateful objects
infrastructure.Signed-off-by: Pablo M. Bermudo Garay

this is needed by the upcoming ct helper object type --
we'd like to be able use the table family (ip, ip6, inet) to figure
out which helper has to be requested.Signed-off-by: Florian Westphal

Dumping of netlink attributes may fail due to insufficient room in the
skbuff, so let's reset consumed quota if we succeed to put netlink
attributes into the skbuff.Fixes: 43da04a593d8 ("netfilter: nf_tables: atomic dump and reset for stateful objects")

Notify on depleted quota objects. The NFT_QUOTA_F_DEPLETED flag
indicates we have reached overquota.Add pointer to table from nft_object, so we can use it when sending the
depletion notification to userspace.Signed-off-by: Pablo Neira Ayuso

This patch adds a new NFT_MSG_GETOBJ_RESET command perform an atomic
dump-and-reset of the stateful object. This also comes with add support
for atomic dump and reset for counter and quota objects.Signed-off-by: Pablo Neira Ayuso

Add a new attribute NFTA_QUOTA_CONSUMED that displays the amount of
quota that has been already consumed. This allows us to restore the
internal state of the quota object between reboots as well as to monitor
how wasted it is.This patch changes the logic to account for the consumed bytes, instead
of the bytes that remain to be consumed.Signed-off-by: Pablo Neira Ayuso

This is patch renames the existing function to nft_overquota() and make
it return a boolean that tells us if we have exceeded our byte quota.
Just a cleanup.Signed-off-by: Pablo Neira Ayuso

This patch adds the quota expression. This new stateful expression
integrate easily into the dynset expression to build 'hashquota' flow
tables.Arguably, we could use instead "counter bytes > 1000" instead, but this
approach has several problems:1) We only support for one single stateful expression in dynamic set
definitions, and the expression above is a composite of two
expressions: get counter + comparison.2) We would need to restore the packed counter representation (that we
used to have) based on seqlock to synchronize this, since per-cpu is
not suitable for this.So instead of bloating the counter expression back with the seqlock
representation and extending the existing set infrastructure to make it
more complex for the composite described above, let's follow the more
simple approach of adding a quota expression that we can plug into our
existing infrastructure.Signed-off-by: Pablo Neira Ayuso
