Changelog

Below you can see the 5 most recent changes to Uberspace 7. For older changes, please refer to the Changelog Archive.

Note

Sometimes the version shown on your host may be higher than the newest version here. In this case we might have applied additional fixes shortly after a release or did internal changes without user impact. We deem updates like these hotfixes and they are not necessarily included in this changelog.

[7.11.4] - 2021-08-19

Added

  • We added a rate limit of 10 requests/sec for two common Wordpress paths: ~.*/wp-login.php and ~.*/xmlrpc.php. These are (for now) based on $server_name only. (This was already rolled out via hotfix some weeks ago)…
  • We now use a a stricter rate limit of 30 requests/min for these request. This is subject to ongoing tweaking and will probably be reduced further in the future (and based also on IP).
  • We now accept strict TLS connections for SMTP relaying on port 465.
  • Added Erlang OTP 24 (along with recent versions for 21, 22 and 23).
  • Elixir was updated too, for the OTP version mentioned above.
  • The npx binary for Node.js is now exposed, based on your selected version.
  • The php-config binary for PHP is now exposed, based on your selected version.

Changed

  • We now limit the number of recipients for SMTP relaying to 100.
  • We now actually limit the max size for mails to 25 MB. (This is stated in our community rules for a long time, but we had not yet enforced it on U7).
  • The uberspace mail domain list command now displays DNS INVALID next to unverified mail domains (along with the time of the last check). While the tool responsible for checking these runs around every 30 seconds, failed MX checks will be retried at most every 3 minutes.
  • We now rotate /var/log/wtmp daily (default was by size) and set the retention period to 7 days.
  • We now delete TLS certificates immediately after removal of domains / accounts (before they where “garbage collected” eventually).
  • We increased some Pigeonhole settings for Sieve: sieve_max_redirects (up to 20 form 4) and sieve_max_actions (up to 64 form 32).
  • nano is now the default editor set by shell profile via $EDITOR and $VISUAL.
  • /opt/nginx/conf/mime.types is now world-readable (i.e. you can include it in your own settings).

Removed

  • Removed Python 3.4 and 3.5.
  • Deprecated Node.js v10. Will be removed soon.

Fixed

  • PHP now uses a per-user session save path (/var/lib/php-sessions/{{account}}/) to allow garbage collection. Before this change, garbage collection failed because of missing permissions.
  • We added our self compiled Python 3.9 to the $CPATH via shell profile. So you no longer have to do that manually before installing compiled packages (e.g. uwsgi).

[7.11.3] - 2021-06-15

Added

  • Support for the editheader capability for Sieve.
  • PHP’s phpize to the $PATH.

Changed

  • Dovecot now ignores a size mismatch between the mail file on disk and the size given in its filename. This should prevent errors, occurring when something changes the mail after it was delivered (e.g. writing an extra header to it, like CRM114).

[7.11.1] - 2021-05-03

Added

  • Node.js v16.
  • inotify-tools

Changed

  • We changed the format of the user access log (again) and added the port after the host. Now the format should be compatible with VCOMBINED / NCSA with VHOST parsers, e.g. GoAccess. E.g.:

    isabell.uber.space:443 10.132.0.0 - - [28/Apr/2021:16:10:23 +0000]
"GET /hello/world.php HTTP/1.1" 200 42 "-" "HTTPie/0.9.4"

  • When adding mail domains, we priviously only accept domains, whose MX record points to the FQDN of the host. Now we also accept domains whose MX record points to a domain, whose A record resolves to the host.

Fixed

  • Our new Dovecot does not play well with qmail (qmail masks SIGCHLD, Dovecot does not unmasks it). Until this is fixed upstream, we added a workaround.

Internal

  • We added more fields to our internal access log.

[7.11.0] - 2021-04-20

Added

  • HEIC support for ImageMagick v6 (already installed for v7).
  • Mod FastCGI for Lighttpd.
  • WebP tooling via libwebp-tools.

Updated

  • We now use the official RPM repo for Dovecot, jumping to version 2.3.14.

Changed

  • We now use TLS v1.2 as minimum version for connections to Dovecot.
  • We switched the format of our web server logs from COMBINED to VCOMBINED (i.e. added $host as first field). This changes the format of ~/logs/webserver/access_log.

Fixed

  • If --remove-prefix option for web backends used for a path not ending in a slash, the prefix was not removed.

Internal

  • Updated node exporter to v1.1.2.
  • We now log full HTTP client IP addresses for 24 hours for internal abuse and spam handling. Weekly and user logs still use anonymized IPs only.

[7.10.0] - 2021-03-04

Added

  • updated Java to 15
  • each users CPU usage is now limited to 6 cores, improving stability.
  • pecl-mailparse
  • HEIC support for ImageMagick 6, and by extension PHP

Changed

  • recommended SPF record is now include:spf.uberspace.de so we can reoute mails more easily. The current records prevents us from relaying mails through another server temporarily.
  • to be consistent with our advice to use .uber.space domains for mail, user.host.uberspace.de is now no longer part of mail domain list.
  • uberspace mail domain add now explains that the trailing dot in MX records is correct, but not necessary or possible to enter in many DNS interfaces.
  • rspamd’s FORGED_RECIPIENTS test now adds fewer points to the spam score to counter many reported false-positive.

Fixed

  • RAM limits for users were not applying consistently, leading to outages in the recent past. We now apply the limits ourselves instead of relying on systemd, increasing stability in the future.
  • Sometimes systemd failed to reload nginx, leading to new domains not being available. We now use the nginx tooling directly instead of relying on systemd’s $MAINPID variable, hopefully fixing this.
  • MySQLs temporary files are now written to SSDs on all hosts, increasing performance for big queries that don’t fit into RAM.

Internal

  • there is a dummy uberspace-letsencrypt-renew script, which does nothing. Many U6 users leave their let’s encrypt cronjob in place, even though U7 does not need one. The resulting cron error mails confuse users, which increases our support volume. The dummy script automates those cases.
  • we rewrote the playbook, which updates MariaDB, enabling updates to 10.4 and 10.5 in the future.
  • some hosts have additional SSD devices for yum, rpm and the systemd journal. Since we are moving all hosts to SSDs, these are not necessary anymore. We wrote a playbook to remove them in the future, making all hosts consistent again.
  • we now detect and automatically ban more mining tools.
  • MySQL backups now only happen for databases, which changed since the last backup. This reduces the system load at night and further increases storage performance and stability.
