From 2ca3dc7701bc9dab82b01e7197c9879f5d8b6ca5 Mon Sep 17 00:00:00 2001 From: Igor Ryzhov Date: Sat, 24 Feb 2024 00:06:41 +0200 Subject: [PATCH] lib: fix nb callbacks for containers inside choice case Containers inside a choice's case must be treated as presence containers as they can be explicitly created and deleted. They must have `create` and `destroy` callbacks, otherwise the internal data they represent may never be deleted. The issue can be reproduced with the following steps: - create an access-list with destination-network params ``` # access-list test seq 1 permit ip any 10.10.10.0 0.0.0.255 ``` - delete the `destination-network` container ``` # mgmt delete-config /frr-filter:lib/access-list[name='test'][type='ipv4']/entry[sequence='1']/destination-network # mgmt commit apply MGMTD: No changes found to be committed! ``` As the `destination-network` container is non-presence, and all its leafs are mandatory, mgmtd doesn't see any changes to be commited and simply updates its YANG data tree without passing any updates to backend daemons. This commit fixes the issue by requiring `create` and `destroy` callbacks for containers inside choice's cases.
