From 9ca08c39af36079809e9247957d86e86009a3e6a Mon Sep 17 00:00:00 2001 From: Zdenek Pytela Date: Thu, 13 Jan 2022 19:23:19 +0100 Subject: [PATCH] Allow systemd-coredump read and write usermodehelper state Reference: https://gitbub.com/fedora-selinux/selinux-policy/commit/9ca08c39af36079809e9247957d86e86009a3e6a Conflict: NA When systemd (PID1) crashes, it freezes and systemd services cannot be started, so coredump handling with systemd-coredump will not work either. As frozen systemd does not collect zombies any longer, it looks reasonable to avoid spawning further processes as much as possible. Therefore systemd-coredump will write "|/bin/false" to the kernel.core_pattern kernel tunable when it detects that it was PID 1 that had crashed to disable coredumping.
