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.
|
