From 4ab1df86719fb9d2b86936b88beb05cf0db5adf6 Mon Sep 17 00:00:00 2001 From: Lichen Liu Date: Fri, 17 Nov 2023 14:15:25 +0800 Subject: [PATCH] kdumpctl: Only returns immediately after an error occurs in check_*_modified Resolves: https://issues.redhat.com/browse/RHEL-10484 Upstream: Fedora Conflict: Missing upstream patch d4e8772("kdumpctl: make do_estimate more robust") commit 741861164e24247e995d47a8284b7493cb73b769 Author: Lichen Liu Date: Mon Oct 30 14:51:59 2023 +0800 kdumpctl: Only returns immediately after an error occurs in check_*_modified Currently is_system_modified will return immediately when check_*_modified return a non-zero value, and the remaining checks will not be executed. For example, if there is a fs-related error exists, and someone changes the kdump.conf, check_files_modified will return 1 and is_system_modified will return 1 immediately. This will cause kdumpctl to skip check_fs/drivers_modified, kdump.service will rebuild the initrd and start successfully, however, any errors should prevent kdump.service from starting. This patch will cause check_*_modifed to continue running until an error occurs or all execution ends.
