[cip-dev][isar-cip-core][PATCH v2 0/4] SWUpdate abort on installing indentical image

[Quirin Gylstorff]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

Use a pre/post function of the SWUpdate handler round robin to check if the given uuid
is already in the current root file system and abort if the uuid matches.

This fixes https://gitlab.com/cip-project/cip-core/isar-cip-core/-/issues/43

Changes in V2:
 - remove RFC
 - Use upstream version instead of patch
 - add comment for variable expension

[cip-dev][isar-cip-core][PATCH v2 3/4] image_uuid: read target_image_uuid

[Quirin Gylstorff]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

This writes the target_image_uuid to the Variable TARGET_IMAGE_UUID
which can be used to validate a update against the root file system.

"${@} is evaluated when the variable is expanded. Variables are expanded
when the are used." [1]

Should we also bump the recipe version, even if there are no
corresponding upstream releases?

On second thought, not critical in the given context as we should not
expect anyone doing packet-based updating for a target that does
image-based updates. And I hope this separate recipe is gone soon if we
get the code into swupdate directly.

Hi!

> Anyway, I will post this patch to CIP ML today.

Let me investigate. We _do_ have that patch in 5.10.y-cip and that
patch does not "simply apply".

commit eb69c07eca22ffd8621d9de9378e4b3ce7965190

    can: rcar_canfd: rcar_canfd_handle_global_receive(): fix IRQ storm on global FIFO receive

Hi!

> Anyway, I will post this patch to CIP ML today.

The code was moved around with

commit 59a641368b460e4d1e8dc58a922915591303bd54
Author: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Date:   Wed Dec 22 13:49:45 2021 +0000

    can: rcar_canfd: Add support for RZ/G2L family
    
    commit 76e9353a80e9e9ff65b362a6dd8545d84427ec30 upstream.

Sometimes later, I see your commit:

commit 702de2c21eed04c67cefaaedc248ef16e5f6b293
Author: Biju Das <biju.das.jz@bp.renesas.com>
Date:   Tue Oct 25 16:56:55 2022 +0100

    can: rcar_canfd: rcar_canfd_handle_global_receive(): fix IRQ storm on global
 FIFO receive

...and yes, it looks like we may want that one.

								Pavel
