[PATCH v1 0/2] Testpmd flow update/destroy fixes

[Danylo Vodopianov]

These patches provide next fixes:
	1. The testpmd command “flow update…“ provides a nullptr as the
	   context variable.
	2. Avoid removal of additional flows after requested number of flows has
	   been already removed.

[PATCH v1 1/2] app/testpmd: fix flow update

[Danylo Vodopianov]

The testpmd command “flow update…“ provides a nullptr as the
context variable.
Thus "flow aged <port_id> destroy" command can not
execute successfully.

Fix was done with next steps
1. Generate new port flow entry to add/replace action(s).
2. Set age contest if exists.
3. Replace flow in the flow list.

Fixes: 2d9c7e56e52c ("app/testpmd: support updating flow rule actions")

I would propose the following phrasing, which I think would be more accurate:

	If actions provided to “flow update…“ command contained an age action,
	Then testpmd did not update the age action context accordingly.

[PATCH v1 2/2] app/testpmd: fix flow destroy

[Danylo Vodopianov]

Avoid removal of additional flows after requested number of flows has
been already removed.

Issue with removal of multiple flows is internal testpmd bug at
port_flow_destroy(). This function goes through all flows and compares
given flow ‘id’ with them. However in some cases it can advance pointer
with “given ID” and thus remove additional flow.

Fixes: de956d5ecf08 ("app/testpmd: support age shared action context")

I think it would be better to rename the commit to: "app/testpmd: fix aged flow destroy"

>

I'm not sure that the issue with port_flow_destroy() is really a bug.
port_flow_destroy() function never assumed that rule array can be freed when it's executing,
and port_flow_aged() just violated that assumption.

Could you please rephrase the commit message to include that info?

This fix will have to be taken into LTS releases. Please add "Cc: stable@dpdk.org"

After the commit message is rephrased, I don't think this comment will be needed.

Please move the flow_id variable declaration to the beginning of the case.
Also, please enclose the case's body in braces, so that flow_id declaration does not leak to the following cases.

Hi everyone 

We kindly ask you to review the patches and fixes for the application testpmd.
The primary purpose of these patches is to provide stable behavior of the feature `flow update` together with `aging`.

We are ready to answer any questions about changes in the patches.

Thanks,
Serhii

[PATCH v2 0/2] Testpmd flow update/destroy fixes

[Danylo Vodopianov]

These patches provide next fixes:
	1. The testpmd command “flow update…“ provides a nullptr as the
	   context variable.
	2. Avoid removal of additional flows after requested number of flows has
	   been already removed.
v2:
	1. Rephase commit messages.
	2. Copy user_id to the flow list for flow_update command.
	3. Enclose the case's body for flow_destroy command in braces.

If actions provided to “flow update…“ command contained an age

Thus "flow aged <port_id> destroy" command can not

Fix was done with next steps
1. Generate new port flow entry to add/replace action(s).
2. Set age context if age action is present.
3. Replace flow in the flow list.

[PATCH v2 2/2] app/testpmd: fix aged flow destroy

[Danylo Vodopianov]

Avoid removal of additional flows after requested number of flows has
been already removed.

port_flow_destroy() function goes through all flows and compares
given flow ‘id’ with them. However in some cases it can advance pointer
with “given ID” and thus remove additional flow.

port_flow_destroy() function never assumed that rule array can be freed
when it's executing, and port_flow_aged() just violated that assumption.

[PATCH v2 0/2] Testpmd flow update/destroy fixes

[Danylo Vodopianov]

These patches provide next fixes:
	1. The testpmd command “flow update…“ provides a nullptr as the
	   context variable.
	2. Avoid removal of additional flows after requested number of flows has
	   been already removed.
v2:
	1. Rephase commit messages.
	2. Copy user_id to the flow list for flow_update command.
	3. Enclose the case's body for flow_destroy command in braces.

[PATCH v2 1/2] app/testpmd: fix flow update

[Danylo Vodopianov]

If actions provided to “flow update…“ command contained an age
action, then testpmd did not update the age action context
accordingly.

Thus "flow aged <port_id> destroy" command can not
execute successfully.

Fix was done with next steps
1. Generate new port flow entry to add/replace action(s).
2. Set age context if age action is present.
3. Replace flow in the flow list.

[PATCH v2 2/2] app/testpmd: fix aged flow destroy

[Danylo Vodopianov]

Avoid removal of additional flows after requested number of flows has
been already removed.

port_flow_destroy() function goes through all flows and compares
given flow ‘id’ with them. However in some cases it can advance pointer
with “given ID” and thus remove additional flow.

port_flow_destroy() function never assumed that rule array can be freed
when it's executing, and port_flow_aged() just violated that assumption.

[PATCH v3 0/2] Testpmd flow update/destroy fixes

[Danylo Vodopianov]

These patches provide next fixes:
	1. The testpmd command “flow update…“ provides a nullptr as the
	   context variable.
	2. Avoid removal of additional flows after requested number of flows has
	   been already removed.
v2:
	1. Rephase commit messages.
	2. Copy user_id to the flow list for flow_update command.
	3. Enclose the case's body for flow_destroy command in braces.

v3:
	1. Update commit message
	2. Aligned variable declaration code style

[PATCH v3 1/2] app/testpmd: fix flow update

[Danylo Vodopianov]

If actions provided to “flow update…“ command contained an age
action, then testpmd did not update the age action context
accordingly.

Thus "flow aged <port_id> destroy" command can not
execute successfully.

Fix was done with next steps
1. Generate new port flow entry to add/replace action(s).
2. Set age context if age action is present.
3. Replace flow in the flow list.

[PATCH v3 2/2] app/testpmd: fix aged flow destroy

[Danylo Vodopianov]

port_flow_destroy() function never assumed that rule array can be freed
when it's executing, and port_flow_aged() just violated that assumption.

In case of flow async create failure, it tries to do a cleanup, but it
wrongly removes a 1st flow (with id 0). pf->id is not set at this
moment and it always is 0, thus 1st flow is removed. A local copy of
flow->id must be used to call of port_flow_destroy() to avoid access
and processing of flow->id after the flow is removed.

[PATCH v2 2/2] app/testpmd: fix aged flow destroy

[Danylo Vodopianov]

Avoid removal of additional flows after requested number of flows has
been already removed.

port_flow_destroy() function goes through all flows and compares
given flow ‘id’ with them. However in some cases it can advance pointer
with “given ID” and thus remove additional flow.

port_flow_destroy() function never assumed that rule array can be freed
when it's executing, and port_flow_aged() just violated that assumption.

Could you please remove the first two paragraphs in the commit message?
I don't think they are relevant.

> 
> port_flow_destroy() function never assumed that rule array can be freed when
> it's executing, and port_flow_aged() just violated that assumption.

Also here, could you please describe what exactly is changed in port_flow_aged?
Current content explains the reason for the bug and the commit should describe how it's fixed.

Could you please refactor these lines as follows?

```
case ACTION_AGE_CONTEXT_TYPE_FLOW: {
uint64_t flow_id;

ctx.pf = container_of(type, struct port_flow, age_type);
flow_id = ctx.pf->id;
```

This is to make the style aligned - variables declared at the beginning of the block.
