net/sched: Fix update of lastuse in act modules implementing stats_update

2018-01-02T18:27:52+00:00

We need to update lastuse to to the most updated value between what
is already set and the new value.
If HW matching fails, i.e. because of an issue, the stats are not updated
but it could be that software did match and updated lastuse.

Fixes: 9fea47d93bcc ("net/sched: act_gact: Update statistics when offloaded to hardware")

net_sched: switch to exit_batch for action pernet ops

2017-12-13T18:58:41+00:00

Since we now hold RTNL lock in tc_action_net_exit(), it is good to
batch them to speedup tc action dismantle.

act_mirred: get rid of mirred_list_lock spinlock

2017-12-06T19:50:13+00:00

TC actions are no longer freed in RCU callbacks and we should
always have RTNL lock, so this spinlock is no longer needed.

act_mirred: get rid of tcfm_ifindex from struct tcf_mirred

2017-12-06T19:50:13+00:00

tcfm_dev always points to the correct netdev and we already
hold a refcnt, so no need to use tcfm_ifindex to lookup again.

If we would support moving target netdev across netns, using
pointer would be better than ifindex.

This also fixes dumping obsolete ifindex, now after the
target device is gone we just dump 0 as ifindex.

Simple cases of overlapping changes in the packet scheduler.

Must easier to resolve this time.

Which probably means that I screwed it up somehow.

Revert "net_sched: hold netns refcnt for each action"

2017-11-09T01:03:09+00:00

This reverts commit ceffcc5e254b450e6159f173e4538215cebf1b59.
If we hold that refcnt, the netns can never be destroyed until
all actions are destroyed by user, this breaks our netns design
which we expect all actions are destroyed when we destroy the
whole netns.

net_sched: hold netns refcnt for each action

2017-11-03T01:30:38+00:00

TC actions have been destroyed asynchronously for a long time,
previously in a RCU callback and now in a workqueue. If we
don't hold a refcnt for its netns, we could use the per netns
data structure, struct tcf_idrinfo, after it has been freed by
netns workqueue.

Hold refcnt to ensure netns destroy happens after all actions
are gone.
