[PATCH net-next v2 00/14] net: qede: convert filter code to use extack

[PATCH net-next v2 00/14] net: qede: convert filter code to use extack

[Asbjørn Sloth Tønnesen]

This series converts the filter code in the qede driver
to use NL_SET_ERR_MSG_*(extack, ...) for error handling.

Patch 1-12 converts qede_parse_flow_attr() to use extack,
along with all it's static helper functions.

qede_parse_flow_attr() is used in two places:
- qede_add_tc_flower_fltr()
- qede_flow_spec_to_rule()

In the latter call site extack is faked in the same way as
is done in mlxsw (patch 12).

While the conversion is going on, some error messages are silenced
in between patch 1-12. If wanted could squash patch 1-12 in a v3, but
I felt that it would be easier to review as 12 more trivial patches.

Patch 13 and 14, finishes up by converting qede_parse_actions(),
and ensures that extack is propagated to it, in both call contexts.

Changelog:

v2:
- Reworked to always add extack as last argument. (Requested by Przemek)

v1: https://lore.kernel.org/netdev/20240507104421.1628139-1-ast@fiberby.net/

[PATCH net-next v2 01/14] net: qede: use extack in qede_flow_parse_ports()

[Asbjørn Sloth Tønnesen]

Convert qede_flow_parse_ports to use extack,
and drop the edev argument.

Convert DP_NOTICE call to use NL_SET_ERR_MSG_MOD instead.

In calls to qede_flow_parse_ports(), use NULL as extack
for now, until a subsequent patch makes extack available.

Only compile tested.

[PATCH net-next v2 09/14] net: qede: use extack in qede_flow_parse_udp_v4()

[Asbjørn Sloth Tønnesen]

Convert qede_flow_parse_udp_v4() to take extack,
and drop the edev argument.

Pass extack in call to qede_flow_parse_v4_common().

In call to qede_flow_parse_udp_v4(), use NULL as extack
for now, until a subsequent patch makes extack available.

Only compile tested.

[PATCH net-next v2 12/14] net: qede: use faked extack in qede_flow_spec_to_rule()

[Asbjørn Sloth Tønnesen]

Since qede_parse_flow_attr() now does error reporting
through extack, then give it a fake extack and extract the
error message afterwards if one was set.

The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().

This fake extack approach is already used by
mlxsw_env_linecard_modules_power_mode_apply() in
drivers/net/ethernet/mellanox/mlxsw/core_env.c

Only compile tested.

Note:
Even through _msg is marked in include/linux/netlink.h as
"don't access directly, use NL_SET_ERR_MSG", then the comment
above NL_SET_ERR_MSG, seams to indicate that it should be fine
to access it directly if for reading, as is done other places.
I could also add a NL_GET_ERR_MSG but I would rather not do that
in this series.

[PATCH net-next v2 13/14] net: qede: propagate extack through qede_flow_spec_validate()

[Asbjørn Sloth Tønnesen]

Pass extack to qede_flow_spec_validate() when called in
qede_flow_spec_to_rule().

Pass extack to qede_parse_actions().

Not converting qede_flow_spec_validate() to use extack for
errors, as it's only called from qede_flow_spec_to_rule(),
where extack is faked into a DP_NOTICE anyway, so opting to
keep DP_VERBOSE/DP_NOTICE usage.

Only compile tested.
