Is it the only reason for the change?
I better understand "shared" even if it is sometimes not shared.

Another reason is as written in the description of commit message, currently the update interface use the rte_flow_action as the input parameter. It would limit the ability of updating, since rte_flow_action only have the "conf" w/o any mask or flag bits.

If only part of the fields need to be updated, it couldn't meet the needs.

Sorry, it is too vague. Context in the RFC looks insufficient
to understand it. Please, provide more details and real-life
examples.

Take the next RFC of "conntrack" for example, in the actions structure definition, there are more than a dozen of fields to define the action itself. When an updating is required, sometimes, only part of these fields need to be updated.
__rte_experimental
int
rte_flow_shared_action_update(uint16_t port_id,
			      struct rte_flow_shared_action *action,
			      const struct rte_flow_action *update,
			      struct rte_flow_error *error);
In the current API, the 3rd input parameter "update" has the same struct type "rte_flow_action", and unlike the "rte_flow_item", no "mask" field is contained in the action struct, only "conf". When doing a update, the software has to take all the information pointed by the "conf" and do a whole update. The partial update couldn't be supported with the current update interface definition.
By changing the pointer type from "const struct rte_flow_action *" to the " const void *", it would be much more flexible.
1. For the current implementation that "update" interface has already been used, only a minor change in the PMD is needed, to cast the generic pointer to the action pointer before getting the new "conf".
2. For the new actions implementation that will use the "update" interface, the pointer type will be depends on the need. If no partial is required, it could be the same as before, a action pointer. Or else, a wrapper structure pointer will be used to indicate which field(s) inside to update.
I hope this description would be a bit more detailed about the purpose of this change.

And since the "update" interface needs to be updated, we could change the other 3 interfaces with proper names. What do you think?

The naming reasons are listed below:
1. The "shared_action*" is incorrect or improper naming of the interface.
2. The "_update" interface needs to be changed to support the partial updating capability.
3. Since we need to modify the update interface, this is a chance to change the improper *experimental* interfaces naming to make them more proper.

It does not explain why "action_ctx" is a better name than "shared_action".

[dpdk-dev] [RFC PATCH v2] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action shoule be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

All the command lines in testpmd application with "shared_action*"
are replaced with "indirect_action*".

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer paramter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

[dpdk-dev] [PATCH] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action shoule be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

All the command lines in testpmd application with "shared_action*"
are replaced with "indirect_action*".

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer paramter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

[dpdk-dev] [PATCH v2 1/4] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

All the command lines in testpmd application with "shared_action*"
are replaced with "indirect_action*".

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Do you mean the release note? I only updated the 20_01 release note part.

In the testpmd usage guide, I found some description and update it together with the testpmd update.
I will check if there is another place to update or add.

Just for the record. I still dislike renaming since "shared" highlights
purpose (what is definitely better), but "indirect" is just a technical
detail on how it is done.

The difference is that indirect action is not only for sharing.
It allows manipulating an action as an object.
Action object is inserted in flow rules through the indirect action.
Does it make it clearer?

Yes, I see thanks.

[dpdk-dev] [PATCH v2 2/4] app/test-pmd: change to indirect action command

[Bing Zhao]

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces are also need to be updated to do the adaption.

[dpdk-dev] [PATCH v2 3/4] doc: update user guide for indirect action

[Bing Zhao]

The testpmd application user guide is updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

[dpdk-dev] [PATCH v2 4/4] net/mlx5: adaption to indirect action API

[Bing Zhao]

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, mlx5 PMD needs to do the
adaption to the new APIs.

Hi Bing,

How the patchset constructed will cause build error in patch by patch build, 
since first patch removes some struct/functions that are in use.

One way to handle this is:
- first add new function/structs
- switch app & pmd to new function/structs
- remove old function/structs


And another issue is this support has been added on 20.11, and we are changing 
it in the second release after it.
Of course it is OK to change the API by time, that is why we have experimental 
APIs, but the concern is if the development is driven by single vendor without a 
consensus or enough reviews, and my worry is if same thing happening again.

The author and reviewers of the original patch is already cc'ed, I think it 
would be good to have their ack to the change.

Thanks,
ferruh

Sure, I will reorganize the patch set in this way. Thanks for this.

The change itself is not big, most of them are the naming convention. The most important change is one input parameter of the "update" interface.
Yes, I agree with your concern. Are there any other reviewers suggested for this change? (I got the name list from the script)
It would be very helpful if they could give some comments or some suggestions.

Yes, I will ping them.

This is a drop-in replacement, it should be done in one patch only.

[dpdk-dev] [PATCH v3 1/1] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

When I read this somehow indirect did not feel right.
But I don't have a strong suggestion either.
Since it is a context of action or actions maybe we use action_context?

The original RFC use the naming proposal "action_context", then there were some comments that it was not as good as "shared action".
The "indirect action" may describe the behavior of the action better than "shared" to my understanding.

In the email from Thomas, the comments may explain it better than mine:
" The difference is that indirect action is not only for sharing.
It allows manipulating an action as an object.
Action object is inserted in flow rules through the indirect action.
Does it make it clearer?"

What do you think?

This is an action which is not directly described in the flow rule,
but in another object referenced by its handle.
It creates a level of indirection in the rule description.
I think the word "indirect" is accurate.

[dpdk-dev] [PATCH v4 1/1] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

A blank line is missing here.

I propose a reword:

* ethdev: The experimental flow API for shared action has been generalized
  as a flow action handle used in rules through an indirect action.
  The functions ``rte_flow_shared_action_*`` manipulating the action object
  are replaced with ``rte_flow_action_handle_*``.
  The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
  replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``.

We should add a comment to RTE_FLOW_ACTION_TYPE_SHARED,
that it is deprecated.

Proposed reword:

An action handle is referenced in a rule through an indirect action.

The same action handle may be used in multiple rules for the same

Can be simpler:
Create an indirect action object that can be used in flow rules via its handle.

[dpdk-dev] [PATCH v5] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

[dpdk-dev] [PATCH v5 1/1] ethdev: introduce indirect action APIs

[Bing Zhao]

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

   ``rte_cryptodev_raw_dequeue_burst`` got a new parameter
   ``max_nb_to_dequeue`` to provide flexible control on dequeue.
 
+* ethdev: The experimental flow API for shared action has been generalized
+  as a flow action handle used in rules through an indirect action.
+  The functions ``rte_flow_shared_action_*`` manipulating the action object
+  are replaced with ``rte_flow_action_handle_*``.
+  The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
+  replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``.
