9790415da1 roles/nginx: use nginx-acme-module for TLS certs 
Use the nginx-acme module for TLS certs instead of acme.sh because
it requires less configuration, less tooling, and works using the
tls-alpn challenge.

3763ce80e1 roles/mariadb: rework to use Debian's mariadb 
There are no MariaDB builds for Debian 13 (trixie) yet. This seems
to happen every new release. Surprisingly Debian's mariadb-server
is very new and we can simplify our tasks and templates a lot.

This is not longer present as of Debian 13, and the old MariaDB key
should not be present on any of my hosts anymore anyway.

8f57a5a974 roles/php_fpm: rework for Debian 13 
We can use metapackages like php-fpm on each version as those pull
in the correct package. This allows us to use the same playbook lo-
gic for Debian 12 (PHP 8.2) and Debian 13 (PHP 8.4).

cac74c53ef roles/common: minor configuration of Debian 13 SSH 
Tweak some of the new OpenSSH per-source penalty settings on Debian
13. For now only adjusting the source network masks and reusing the
list of IPs to exempt from fail2ban.

These being built in makes them easier to use, but I think I will
end up sticking with fail2ban for the heavy lifting because it per-
sists across restarts of the daemon, whereas OpenSSH's doesn't. I
will monitor OpenSSH on Debian 13 to see how to best use it along
side fail2ban.

078c5b36d8 roles/common: use 127.0.0.0/8 for fail2ban ignoreip 
We can re-use our fail2ban ignoreip setting for Debian 13's OpenSSH
PerSourcePenaltyExemptList, but OpenSSH is more strict with regards
to masks not being applied to the host portion. I had never noticed
that fail2ban's default was applying the mask on the host portion!

a315db8a7c roles/common: use ansible_distribution_version

we use Ansible's version comparison function. We rarely need to use
the major version (ie 12) directly.

00558c7dea roles/common: re-work fail2ban and nftables 
Re-work the fail2ban and nftables interaction. Use systemd's PartOf
to indicate that fail2ban is part of the nftables service, which
tells systemd to propogate stop/start signals to it. Then we tell
the firehol update script to restart nftables instead of reload.
The different between restart and reload is meaningless for nftables
but we want systemd to propagate the stop/start signals to fail2ban.

c927186837 roles/common: adjust update-firehol-nftables.service 
This service does not actually depend on nftables, at least not in
the systemd sense of dependency. Furthermore, this hard dependency
was causing the service to fail when it restarts nftables at the
end, which causes systemd to start it again and again until it hits
a restarting too quickly error.

9a500ebc0d roles/nginx: disable nginx ssl_prefer_server_ciphers 
This is apparently the default and recommended by Mozilla's server-

0afb8a4493 roles/nginx: update nginx ssl_buffer_size 
The old default has not been changed in eight years and I see that
there have been some discussions over the years about this. I will
change this from the slightly extreme 1400 bytes to 4k (nginx def-
ault is still 16k so this is more "optimal" for HTML/CSS content).

22c16e1ed3 roles/caddy/templates: closer to supporting WordPress 
I still wouldn't want to deploy WordPress on Caddy until it's more
obvious and standard to block paths that shouldn't be accessible.
It seems that this is still left as an exercise to the site admin.

This discussion has some tips, but it is four years old and hasn't
changed since I last looked.

to hosts running nginx.

ebd8b0632b roles/common: Disable unsafe Diffie-Hellman SSH moduli 
The WeakDH team showed (in 2015) that Diffie-Hellman key exchange
with prime number groups of 1024 bits or less were weaker than we
previously thought, and well within the reach of nation states. They
recommended (in 2015) using 2048-bit or higher prime groups.

The SSH audit project recommends that we should use 3072-bit now.

First, we cannot do a global check for has_wordpress or needs_php,
as those are defined per nginx vhost. Second, I realized that this
was only working in the past because vhosts that had WordPress or
needed PHP were listed first in the nginx_vhosts dict.

This changes the logic to first check if any vhosts have WordPress
or need PHP, then sets a fact that we can use to decide whether to
run php-fpm tasks or not.

can be banned immediately.

This also includes a systemd service, timer, and script to update

Note that there is currently an issue loading the spamhaus rules on

The bug is apparently caused by overlapping CIDR segments, and the
solution appears to be that we need to manually aggregate them with
a tool like aggregate6 (Python).

d7c34a30a3 roles/common: Add Spamhaus DROP lists to firewalld ipsets 
This configures the recommended DROP, EDROP, and DROPv6 lists from
Spamhaus as ipsets in firewalld. First we copy an empty placeholder
ipset to seed firewalld, then we use a shell script to download the
real lists and activate them. The same shell script is run daily as
a service (update-spamhaus-lists.service) by a systemd timer.

I am strictly avoiding any direct ipset commands here because I want
to make sure that this works on older hosts where ipsets is used as
well as newer hosts that have moved to nftables such as Ubuntu 20.04.
So far I have tested this on Ubuntu 16.04, 18.04, and 20.04, but ev-
entually I need to abstract the tasks and run them on CentOS 7+ as
well.

that I can start using ECC certificates.

This also configures the .well-known directory so we can use webroot
when installing and renewing certificates. I have yet to understand
how the renewal works with regards to webroot, though. I may have to
update the systemd timers to point to /var/lib/letsencrypt/.well-known.

  $ curl -G https://api.abuseipdb.com/api/v2/blacklist -d \
    confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" \
    -H "Accept: text/plain" | sort | sed -e '/:/w /tmp/ipv6.txt' \
    -e '/:/d' > /tmp/ipv4.txt

I manually add the XML formatting to each file and run them through
tidy:

  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv4.xml
  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv6.xml

8ee52143fc roles/mariadb: Disable the query cache by default 
It seems that the usefulness of the query cache is diminishing in
recent years. If your cache is large then the time taken to scan
the cache can be longer than the SQL query itself.

; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.

;pm.status_path = /status
; The ping URI to call the monitoring page of FPM. If this value is not set, no

; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow
; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0
; Depth of slow log stack trace.
; Default Value: 20
;request_slowlog_trace_depth = 20
; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.

; Default Value: system defined value
;rlimit_core = 0
; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =
; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www
; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
catch_workers_output = yes
; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no
; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7
; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp
; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines which can
; be overwritten from PHP call 'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.
; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr)
; Default Value: nothing is defined by default except the values in php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
