Merge branch 'tc_action_ops-refactor'

Zhengchao Shao says:

====================
net: refactor the walk and lookup hook functions in tc_action_ops

The implementation logic of the walk/lookup hook function in each action
module is the same. Therefore, the two functions can be reconstructed.
When registering tc_action_ops of each action module, the corresponding
net_id is saved to tc_action_ops. In this way, the net_id of the
corresponding module can be directly obtained in act_api without executing
the specific walk and lookup hook functions. Then, generic functions can
be added to replace the walk and lookup hook functions of each action
module. Last, modify each action module in alphabetical order.

Reserve the walk and lookup interfaces and delete them when they are no
longer used.

This patchset has been tested by using TDC, and I will add selftest in
other patchset.

Last, thanks to Jamal Hadi Salim and Cong Wang for their advice.

----

- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.

- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).

- Continue work annotating skb drop reasons.

- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.

- Add VLAN support for AF_PACKET SOCK_RAW GSO.

- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.

- Add support for BPF link iterator.

- Introduce access to remote CPU map elements in BPF per-cpu map.

- Allow middle-of-the-road settings for the

out-of-sequence data (partial support for RFC8684 fallback).

- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.

- Support lockless operation of GRE tunnels with seq numbers enabled.

net: sched: use queue_mapping to pick tx queue

This patch fixes issue:
* If we install tc filters with act_skbedit in clsact hook.
It doesn't work, because netdev_core_pick_tx() overwrites
queue_mapping.

$ tc filter ... action skbedit queue_mapping 1

And this patch is useful:
* We can use FQ + EDT to implement efficient policies. Tx queues
are picked by xps, ndo_select_queue of netdev driver, or skb hash
in netdev_core_pick_tx(). In fact, the netdev driver, and skb
hash are _not_ under control. xps uses the CPUs map to select Tx
queues, but we can't figure out which task_struct of pod/containter
running on this cpu in most case. We can use clsact filters to classify
one pod/container traffic to one Tx queue. Why ?

In containter networking environment, there are two kinds of pod/
containter/net-namespace. One kind (e.g. P1, P2), the high throughput
is key in these applications. But avoid running out of network resource,
the outbound traffic of these pods is limited, using or sharing one
dedicated Tx queues assigned HTB/TBF/FQ Qdisc. Other kind of pods
(e.g. Pn), the low latency of data access is key. And the traffic is not
limited. Pods use or share other dedicated Tx queues assigned FIFO Qdisc.
This choice provides two benefits. First, contention on the HTB/FQ Qdisc
lock is significantly reduced since fewer CPUs contend for the same queue.
More importantly, Qdisc contention can be eliminated completely if each
CPU has its own FIFO Qdisc for the second kind of pods.

There must be a mechanism in place to support classifying traffic based on
pods/container to different Tx queues. Note that clsact is outside of Qdisc
while Qdisc can run a classifier to select a sub-queue under the lock.

In general recording the decision in the skb seems a little heavy handed.
This patch introduces a per-CPU variable, suggested by Eric.

The xmit.skip_txqueue flag is firstly cleared in __dev_queue_xmit().
- Tx Qdisc may install that skbedit actions, then xmit.skip_txqueue flag
is set in qdisc->enqueue() though tx queue has been selected in
netdev_tx_queue_mapping() or netdev_core_pick_tx(). That flag is cleared
firstly in __dev_queue_xmit(), is useful:
- Avoid picking Tx queue with netdev_tx_queue_mapping() in next netdev
in such case: eth0 macvlan - eth0.3 vlan - eth0 ixgbe-phy:
For example, eth0, macvlan in pod, which root Qdisc install skbedit
queue_mapping, send packets to eth0.3, vlan in host. In __dev_queue_xmit() of
eth0.3, clear the flag, does not select tx queue according to skb->queue_mapping
because there is no filters in clsact or tx Qdisc of this netdev.
Same action taked in eth0, ixgbe in Host.
- Avoid picking Tx queue for next packet. If we set xmit.skip_txqueue
in tx Qdisc (qdisc->enqueue()), the proper way to clear it is clearing it
in __dev_queue_xmit when processing next packets.

For performance reasons, use the static key. If user does not config the NET_EGRESS,
the patch will not be compiled.

====================
net/sched: Better error reporting for offload failures

This patchset improves error reporting to user space when offload fails
during the flow action setup phase. That is, when failures occur in the
actions themselves, even before calling device drivers. Requested /
reported in [1].

This is done by passing extack to the offload_act_setup() callback and
making use of it in the various actions.

Patches #1-#2 change matchall and flower to log error messages to user
space in accordance with the verbose flag.

Patch #3 passes extack to the offload_act_setup() callback from the
various call sites, including matchall and flower.

Patches #4-#11 make use of extack in the various actions to report
offload failures.

Patch #12 adds an error message when the action does not support offload
at all.

Patches #13-#14 change matchall and flower to stop overwriting more
specific error messages.
