[patch net-next v3 00/12] devlink: use spec to generate split ops

[patch net-next v3 00/12] devlink: use spec to generate split ops

[Jiri Pirko]

From: Jiri Pirko <jiri@nvidia.com>

This is an outcome of the discussion in the following thread:
https://lore.kernel.org/netdev/20230720121829.566974-1-jiri@resnulli.us/
It serves as a dependency on the linked selector patchset.

There is an existing spec for devlink used for userspace part
generation. There are two commands supported there.

This patchset extends the spec so kernel split ops code could
be generated from it.

[patch net-next v3 02/12] ynl-gen-c.py: filter rendering of validate field values for split ops

[Jiri Pirko]

From: Jiri Pirko <jiri@nvidia.com>

For split ops, do and dump has different meaningful values in
validate field.

Fix the rendering to allow the values per op type as follows:
do: strict
dump: dump, strict-dump

For kernel mode, the code is generated correctly using right cmd values

as a thin wrapper around iteration function and allow to pass dump_one()
function pointer directly without need to store in devlink_cmd structs.

[patch net-next v3 08/12] devlink: un-static devlink_nl_pre/post_doit()

[Jiri Pirko]

From: Jiri Pirko <jiri@nvidia.com>

To be prepared for the follow-up generated split ops addition,
make the functions devlink_nl_pre_doit() and devlink_nl_post_doit()
usable outside of netlink.c. Introduce temporary prototypes which are
going to be removed once the generated header will be included.

[patch net-next v3 10/12] devlink: add split ops generated according to spec

[Jiri Pirko]

From: Jiri Pirko <jiri@nvidia.com>

Improve the existing devlink spec in order to serve as a source for
generation of valid devlink split ops for the existing commands.
Add the generated sources.

Node that the policies are narrowed down only to the attributes that
are actually parsed. The dont-validate-strict parsing policy makes sure
that other possibly passed garbage attributes from userspace are
ignored during validation.

Signed-off-by: Jiri Pirko <jiri@nvidia.com>

v2->v3:
- un-static devlink_nl_pre/post_doit() to fix the build
v1->v2:
- fixed "for" typo
- added note to patch description about narrowing down the policy
- moved info-get dump op addition to a separate patch
- regenerated files according to static policies change

[patch net-next v3 12/12] devlink: use generated split ops and remove duplicated commands from small ops

Do the switch and use generated split ops for get and info_get commands.
Remove those from small ops array.
