This series patches adds support for VCAP IS1 and ES0 module.
VCAP IS1 supports FLOW_ACTION_VLAN_MANGLE action to filter MAC, IP,
VLAN, protocol, and TCP/UDP ports keys and retag vlan tag.
VCAP ES0 supports FLOW_ACTION_VLAN_PUSH action to filter vlan keys
and push a specific vlan tag to frames.

From: Vladimir Oltean <vladimir.oltean@nxp.com>
There are some targets (register blocks) in the Ocelot switch that are
instantiated more than once. For example, the VCAP IS1, IS2 and ES0
blocks all share the same register layout for interacting with the cache
for the TCAM and the action RAM.
For the VCAPs, the procedure for servicing them is actually common. We
just need an API specifying which VCAP we are talking to, and we do that
via these raw ocelot_target_read and ocelot_target_write accessors.
In plain ocelot_read, the target is encoded into the register enum
itself:
u16 target = reg >> TARGET_OFFSET;
For the VCAPs, the registers are currently defined like this:
enum ocelot_reg {
[...]
S2_CORE_UPDATE_CTRL = S2 << TARGET_OFFSET,
S2_CORE_MV_CFG,
S2_CACHE_ENTRY_DAT,
S2_CACHE_MASK_DAT,
S2_CACHE_ACTION_DAT,
S2_CACHE_CNT_DAT,
S2_CACHE_TG_DAT,
[...]
};
which is precisely what we want to avoid, because we'd have to duplicate
the same register map for S1 and for S0, and then figure out how to pass
VCAP instance-specific registers to the ocelot_read calls (basically
another lookup table that undoes the effect of shifting with
TARGET_OFFSET).
So for some targets, propose a more raw API, similar to what is
currently done with ocelot_port_readl and ocelot_port_writel. Those
targets can only be accessed with ocelot_target_{read,write} and not
with ocelot_{read,write} after the conversion, which is fine.
The VCAP registers are not actually modified to use this new API as of
this patch. They will be modified in the next one.

From: Vladimir Oltean <vladimir.oltean@nxp.com>
The Ocelot driver only supports VCAP IS2, the security enforcement block
which implements Access Control List actions (trap, drop, police).
In preparation of VCAP IS1 support, generalize the existing code to work
with any VCAP. In that direction, move all VCAP instantiation-specific
data to struct vcap_props, and pass that as an argument to each function
that does the key and action packing. Only the high-level functions need
to have access to ocelot->vcap[VCAP_IS2].

When calculating vcap data offset, the function only supports half key
entry. This patch modify vcap_data_offset_get function to calculate a
correct data offset when setting VCAP Type-Group to VCAP_TG_FULL or
VCAP_TG_QUARTER.

VCAP IS1 is a VCAP module which can filter MAC, IP, VLAN, protocol, and
TCP/UDP ports keys, and do Qos and VLAN retag actions.
This patch added VCAP IS1 support in ocelot ace driver, which can supports
vlan modify action of tc filter.
Usage:
tc qdisc add dev swp0 ingress
tc filter add dev swp0 protocol 802.1Q parent ffff: flower \
skip_sw vlan_id 1 vlan_prio 1 action vlan modify id 2 priority 2

I skimmed skimmed through the patch serie, and the way I understood it
is that you look at the action, and if it is a VLAN operation, then you
put it in IS1 and if it is one of the other then put it in IS2.
This is how the HW is designed - I'm aware of that.
But how will this work if you have 2 rules, 1 modifying the VLAN and
another rule dropping certain packets?
The SW model have these two rules in the same table, and can stop
process at the first match. SW will do the action of the first frame
matching.
The HW will how-ever do both, as they are in independent TCAMs.
If we want to enable all the TCAM lookups in Ocelot/Felix, then we need
to find a way where we will get the same results when doing the
operation in HW and in SW.

At the moment, the driver does not support more than 1 action. We
might need to change that, but we can still install more filters with
the same key and still be fine (see more below). When there is more
than 1 action, the IS1 stuff will be combined into a single rule
programmed into IS1, and the IS2 stuff will be combined into a single
new rule with the same keys installed into VCAP IS2. Would that not
work?

Actually I think this is an incorrect assumption - software stops at
the first action only if told to do so. Let me copy-paste a text from
a different email thread.
"
Thank you for the good discussion today.
I think the key talking points were:
- How to express with tc filters the fact that some actions are
executed by different hardware pipelines than others (VCAP IS1: vlan
retagging and QoS classification, VCAP IS2: trap, drop, police), and
that those pipelines can be completely independent, as well as chained
via a policy
- How to express the fact that VCAP IS1 can perform up to 3 parallel
lookups (and VCAP IS2 can perform 2 lookups) per frame with
potentially different key types and different actions.
I am trying to take a different (top-down) approach than Allan, which
is to try to express the capabilities that we are interested in
offloading to Ocelot/Felix as software (skip_hw) tc filters first.
It was said during the call that flow classification stops at the
first action that matches a frame, which would prevent us from adding
actions for the VCAP IS1 in the same chain as actions for the VCAP
IS2.
Actually it seems that it is possible to specify to the flow
classifier what to do after each individual action, as can be seen in
the man page of tc-actions
(http://man7.org/linux/man-pages/man8/tc-actions.8.html):
CONTROL
The CONTROL indicates how tc should proceed after executing
the action. Any of the following are valid:
reclassify
Restart the classifiction by jumping back to the first
filter attached to the action's parent.
pipe Continue with the next action. This is the default
control.
drop Drop the packed without running any further actions.
continue
Continue the classification with the next filter.
pass Return to the calling qdisc for packet processing, and
end classification of this packet.
In the above description, it says that "pipe" is the default action
control. My experience does not seem to coincide with that.
I wrote this quick list of software filters:
tc qdisc add dev swp0 clsact
# IS1
tc filter add dev swp0 ingress protocol ip flower skip_hw src_ip
192.168.1.1 hw_tc 5
tc filter add dev swp0 ingress protocol all flower skip_hw action vlan push id 3
tc filter add dev swp0 egress protocol 802.1Q flower skip_hw action vlan pop
# IS2
swp0_mac=$(ip link show dev swp0 | awk '/link\/ether/ {print $2}')
tc filter add dev swp0 ingress protocol all flower skip_hw dst_mac
${swp0_mac} action police rate 37Mbit burst 64k
ip link add link swp0 name swp0.3 type vlan id 3 && ip link set dev swp0.3 up
which would permit me to terminate IP traffic on the swp0.3 VLAN
sub-interface, over which I ran an iperf3 test.
The traffic _was_ successfully rate limited at 37 Mbps, _and_
retagged, but I got a lot of these errors coming from tcf_classify:

basically the "vlan push" rule matches on way less packets than I was
expecting, and the default control for the police action is to
reclassify, not to pipe. I think this is an odd choice for a default
value, but it looks like I can specify the police rule like this
(using conform-exceed):
tc filter add dev swp0 ingress protocol all flower skip_hw dst_mac
${swp0_mac} action police rate 37Mbit burst 64k conform-exceed
drop/pipe
Basically the idea I want to transmit is that the impression we had
during the call does not seem to hold true. The default action control
is "pipe" (well, it's "almost" default), which has the effect of going
through all rules and not just through the first one that matches
(that would be the "pass" control). So in principle I don't see why we
couldn't model the actions that require VLAN retagging or QoS
classification as lookups in IS1 (ES0 might also need to be involved
in the retagging case, I am not 100% sure how the egress rewriter is
involved in the retagging process, but it seems like it is), and the
actions that require dropping, trapping or policing as lookups in IS2.
I am not sure that chains would be necessary, nor that we could use
them anyway (given that we can't make a chain template based on action
types).
As for the other point (multiple TCAM lookups in the same block), I
think some concrete examples would definitely help.
The example of supporting matches on src_mac and src_ip simultaneously
is a valid one, but it can be dealt with just privately by the driver.
Looking for concrete examples where that would not be enough.
Another item I would like to bring up is how to perform QoS
classification. In my example I used the "hw_tc" action from
tc-flower, but not being offloaded, I couldn't test it. Is this how it
should be done? Is there an equivalent to hw_tc in tc-matchall and in
tc-u32? We might need them there too.

I'm still not able to see how this proposal will give us the same
behavioral in SW and in HW.
A simple example:
tc qdisc add dev enp0s3 ingress
tc filter add dev enp0s3 protocol 802.1Q parent ffff: \
prio 10 flower vlan_id 5 action vlan modify id 10
tc filter add dev enp0s3 protocol 802.1Q parent ffff: \
prio 20 flower src_mac 00:00:00:00:00:08 action drop
We can then inject a frame with VID 5 and smac ::08:
$ ef tx tap0 eth smac 00:00:00:00:00:08 ctag vid 5
We can then check the filter and see that it only hit the first rule:
$ tc -s filter show dev enp0s3 ingress
filter protocol 802.1Q pref 10 flower chain 0
filter protocol 802.1Q pref 10 flower chain 0 handle 0x1
vlan_id 5
not_in_hw
action order 1: vlan modify id 10 protocol 802.1Q priority 0 pipe
index 1 ref 1 bind 1 installed 19 sec used 6 sec
Action statistics:
Sent 42 bytes 1 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
filter protocol 802.1Q pref 20 flower chain 0
filter protocol 802.1Q pref 20 flower chain 0 handle 0x1
src_mac 00:00:00:00:00:08
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 1 bind 1 installed 11 sec used 11 sec
Action statistics:
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
If this was done with the proposed HW offload, then both rules would
have been hit and we would have a different behavioral.
This can be fixed by adding the "continue" action to the first rule:
tc filter add dev enp0s3 protocol 802.1Q parent ffff: \
prio 10 flower vlan_id 5 action vlan modify id 10 continue
tc filter add dev enp0s3 protocol 802.1Q parent ffff: \
prio 20 flower src_mac 00:00:00:00:00:08 action drop
But that would again break if we add 2 rules manipulating the VLAN (as
the HW does not continue with in a single TCAM).
My point is: I do not think we can hide the fact that this is done
in independent TCAMs in the silicon.
I think it is possible to do this with the chain feature (even though it
is not a perfect match), but it would require more analysis.

Do you mean it's better to set vlan modify filters in a different chain, and write the filter entries with a same chain in the same VCAP TCAM?
For example:
tc filter add dev enp0s3 protocol 802.1Q chain 11 parent ffff: prio 10 flower skip_sw vlan_id 5 action vlan modify id 10
tc filter add dev enp0s3 protocol 802.1Q chain 22 parent ffff: prio 20 flower skip_sw src_mac 00:00:00:00:00:08 action drop
for this usage, we only need to ensure a chain corresponding to a VCAP in ocelot ace driver. I'm not sure is my understanding right?

Xiaoliang

I still have not found a satisfying solution to this. As I understand
the chains, they require the "goto" action to be used to tie them
together.
We could use that to represent a single lookup in is1 and link that to a
lookup in is2. Not sure if we should, it will also require
(non-backwards compatible) changes in how the existing IS2 support is
working.
Again, I do not have the answer (I'm also looking for it), but I think
we need something where it is clear to the user that this end up in
different lists.
