  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

From: Vladimir Medvedkin <vladimir.medvedkin@intel.com>

Replace custom attr checks with a call to common checks. Switch engine
supports priority (0 or 1) but other engines don't, so we move the
attribute checks into the engines.

* [PATCH v7 21/27] net/iavf: use common action checks for fsub
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common flow action checking parsing infrastructure for checking
flow actions for flow subscription filter.

Existing implementation had a couple issues that do not rise to the level
of being bugs, but are still questionable design choices.

For one, DROP action is supported in actions check (single actions are
allowed as long as it isn't RSS or QUEUE) but is later disallowed in action
parse (because not having port representor action is treated as an error).
This is fixed by removing DROP action support from the check stage.

For another, PORT_REPRESENTOR action was incrementing action counter but
not writing anything into action array, which, given that action list is
zero-initialized, meant that the default action (drop) was kept in the
action list. However, because the actual PF treats drop as a no-op, nothing
bad happened when a DROP action was added to the list of actions.

However, nothing bad also happens if we just didn't have an action to
begin with, so we remedy these unorthodox semantics by accordingly
treating PORT_REPRESENTOR action as a noop, and not adding anything to
the action list.

As a final note, now that all filter parsing code paths use the common
action check infrastructure, we can remove the NULL check for actions
from the beginning of the parsing path, as this is now handled by each
engine.

  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Replace custom attr checks with a call to common checks. Flow subscription
engine supports priority but other engines don't, so we move the attribute
checks into the engines.

* [PATCH v7 16/27] net/i40e: use common action checks for tunnel
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common flow action checking parsing infrastructure for checking
flow actions for flow director tunnel filter. As a result, more stringent
checks are performed against parametersm specifically the following:

- reject NULL conf for VF action (instead of attempt at NULL dereference)
- second action was expected to be QUEUE but if it wasn't it was ignored

* [PATCH v7 13/27] net/i40e: refactor RSS flow parameter checks
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Currently, the hash parser parameter checks are somewhat confusing as they
have multiple mutually exclusive code paths and requirements, and it's
difficult to reason about them because RSS flow parsing is interspersed
with validation checks.

To address that, refactor hash engine error checking to perform almost all
validation at the beginning, with only happy paths being implemented in
actual parsing functions.

Some parameter combinations that were previously ignored (and perhaps
produced a warning) are now explicitly rejected:

- if no pattern is specified, RSS types are rejected
- for queue lists and regions, RSS key is rejected

* [PATCH v7 12/27] net/i40e: use common flow attribute checks
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

There is no need to call the same attribute checks in multiple places
when there are no cases where we do otherwise. Therefore, remove all the
attribute check calls from all filter call paths and instead check the
attributes once at the very beginning of flow validation, and use common
flow attribute checks instead of driver-local ones.

Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>
Acked-by: Bruce Richardson <bruce.richardson@intel.com>

* [PATCH v7 11/27] net/ixgbe: use common checks in RSS filter
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common attr and action parsing infrastructure in RSS filter. As a
result, some checks have become more stringent, in particular:

- the group attribute is now explicitly rejected instead of being ignored
- the priority attribute was previously allowed but rejected values bigger
  than 0xFFFF despite not using priority anywhere - it is now rejected

  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

instead of being ignored.

* [PATCH v7 09/27] net/ixgbe: use common checks in security filter
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common attr and action parsing infrastructure in security filter.
As a result, some checks have become more stringent. In particular, group
attribute is now explicitly rejected instead of being ignored.

* [PATCH v7 07/27] net/ixgbe: use common checks in L2 tunnel filter
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common attr and action parsing infrastructure in L2 tunnel filter.
Some checks have become more stringent as a result, in particular, group
attribute is now explicitly rejected instead of being ignored.

  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common attr and action parsing infrastructure in syn filter. Some
checks have been rearranged or become more stringent due to using common
infrastructure. In particular, group attr was ignored previously but is
now explicitly rejected.

* [PATCH v7 05/27] net/ixgbe: use common checks in ethertype filter
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Vladimir Medvedkin
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Use the common attr and action parsing infrastructure in ethertype. This
allows us to remove some checks as they are no longer necessary (such as
whether DROP flag was set - if we do not accept DROP actions, we do not set
the DROP flag), as well as make some checks more stringent (such as
rejecting more than one action).

* [PATCH v7 04/27] net/intel/common: add common flow attr validation
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

There are a lot of commonalities between what kinds of flow attr each Intel
driver supports. Add a helper function that will validate attr based on
common requirements and (optional) parameter checks.

Things we check for:
- Rejecting NULL attr (obviously)
- Ingress/egress according to requested params
- Transfer, group, and priority are not allowed unless requested

* [PATCH v7 03/27] net/intel/common: add common flow action parsing
From: Anatoly Burakov @ 2026-06-04 16:19 UTC (permalink / raw)
  To: dev, Bruce Richardson
In-Reply-To: <cover.1780589913.git.anatoly.burakov@intel.com>

Currently, each driver has their own code for action parsing, which results
in a lot of duplication and subtle mismatches in behavior between drivers.

Add common infrastructure, based on the following assumptions:

- All drivers support at most 32 actions at once, but usually far less
- Not every action is supported by all drivers
- We can check a few common things to filter out obviously wrong actions
- Driver performs semantic checks on all valid actions

So, the intention is to reject everything we can reasonably reject at the
outset without knowing anything about the drivers, parametrize what is
trivial to parametrize, and leave the rest for the driver to implement.

While we're at it, also add logging infrastructure for Intel common code,
using the new component name defines that are automatically passed to each
DPDK driver as it is being built.
