roles/nginx: generate snakeoil cert manually
The ssl-cert does this, but it includes the hostname of the server

roles/common: fix logic for copying AbuseIPDB.com nft sets

roles/common: Update list of abusive IP addresses
This comes from the AbuseIPDB with a confidence level of 95%. I use

roles/php-fpm: Fix logic
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.

roles/common: Fix fail2ban ignoreip
According to jail.conf we actually need to separate multiple values
with spaces instead of commas. On some versions of fail2ban this is
a fatal error:

This affects (at least) fail2ban 0.9.3 on Ubuntu 16.04, but I never
noticed.

Add nginx filter for fail2ban
Some hosts can use fail2ban's nginx-botsearch filter to ban anyone
making requests to non-existent files like wp-login.php. There is
no reason to request such files naively and anyone found doing so
can be banned immediately.

In theory I should report them to AbuseIPDB.com, but that will take
a little more wiring up.

roles/common: Start nftables service later
We should only try to start the nftables service after we finish

state in one of them. On a first run this shouldn't matter, but
after nftables and some abuse list update scripts have run this
can happen (mostly in testing!).

cron-apt updates the system against the security-only databases at

the beginning of the playbook.

roles/common: Add initial support for nftables on Debian 11
I will try using nftables directly instead of via firewalld as of
Debian 11 as it is the replacement for the iptables/ipset stack in
recent years and is easier to work with.

This also includes a systemd service, timer, and script to update
the spamhaus DROP lists as nftables sets.

Still need to add fail2ban support.

roles/common: bring Ubuntu firewall changes to Debian 11
Note that there is currently an issue loading the spamhaus rules on
Debian 11 when using ipsets with firewalld and the nftables backend.
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).

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.

systems so I decided to switch to the acme.sh client, which is imp-
lemented in POSIX shell with no dependencies. One bonus of this is
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.

roles/mariadb: Disable name lookups
Add skip-name-resolve=1 to disable lookups of hostnames to IPs. We
need to make sure all accounts are using IPs like 127.0.0.1 instead
of "localhost" now.

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.

roles/common: Update list of abusive IP addresses
This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:

  $ 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:
