webgateway: update haproxy to 2.3.14 for a critical security fix (CVE-2021-40346) (#PL-130098).
Use OpenSSH 8.7 for ssh/sshd. This fixes frequent sshd crashes caused by
malicious connection attempts that fail. This update has potentially
imcompatible changes that won't affect common use of ssh.
See https://www.openssh.com/releasenotes.html for details (#PL-130095).
Mailserver: fix building the example config if there's no config file, yet.
Already released as hotfix (#PL-130086).
fc-agent: various logging fixes and improvements. Nix build errors are now
easier to find in the journal and Graylog (#PL-130088).
journalbeat: add option flyingcircus.journalbeat.fields.
This is used by default to add VM metadata to log messages that are sent out
to loghosts/Graylog (#PL-130085).
jornalbeat: add VM resources info (cores, disk, iops, memory) to log messages (#PL-130097).
fc-agent and fc-garbage-collect: apply CPU/IO limitations and low priority
settings via SystemD units to avoid load peaks and resulting alerts.
This is often caused by iowait on HDD VMs.
We tried to limit the impact before by using ionice and by limiting the
amount of collected garbage but we still had problems on mostly idle
machines or when agent and garbage collection ran at the same time (#PL-130083).
Ignore "other error" count on drives controlled by MegaRAID controllers to
reduce monitoring noise (#PL-130057).
