Fedora: 2019-616045ca76 Critical: Systemd Memory Leak Fix

fedora
Calendar Grey March 31, 2019
Dist Fedora Esm H88
This update focuses on resolving a critical memory exhaustion issue and enhancing the boot loader functionality for systemd on Fedora 30.
In systemd: backport of bunch of patches from the v242 release

Summary

systemd is a system and service manager that runs as PID 1 and starts

the rest of the system. It provides aggressive parallelization

capabilities, uses socket and D-Bus activation for starting services,

offers on-demand starting of daemons, keeps track of processes using

Linux control groups, maintains mount and automount points, and

implements an elaborate transactional dependency-based service control

logic. systemd supports SysV and LSB init scripts and works as a

replacement for sysvinit. Other parts of this package are a logging daemon,

utilities to control basic system configuration like the hostname,

date, locale, maintain a list of logged-in users, system accounts,

runtime directories and settings, and daemons to manage simple network

configuration, network time synchronization, log forwarding, and name

resolution.

In systemd: backport of bunch of patches from the v242 release. Most important:

- kernel-install will not create the boot loader entry automatically - a memory

leak is fixed. In grub2: - 10_linux_bls: don't add --users option to generated

menu entries (#1693515) - Only set blsdir if /boot/loader/entries is in a btrfs

or zfs partition (#1688453) - Fix some BLS snippets not being displayed in the

GRUB menu (#1691232) - Never remove boot loader configuration for other boot

loaders from the ESP (#1648907) - Do not mask systemd's kernel-install

scriptlets. No need to log out or reboot.
