Adds an abuse detection ban‑feed to efficiently track abusive IPs.

Full changelog

This is a hotfix release, useful pretty much only for ntfy.sh. It was adds the ability to track abusive IPs mor efficiently, reducing the load on the IP banning services and preventing them from falling behind and leaving abusers unbanned for too long. It works by tracking HTTP errors, and writing out a ban file that fail2ban can read and ban offenders instantly. See ban-feed for details.

Features:

  • Add an abuse ban-feed: when enabled via ban-file, ntfy tracks a weighted strike budget per visitor and appends abusive IPs to a file that fail2ban can tail and ban on sight (ban-file, ban-window, ban-threshold, ban-weights; see ban-feed)
