Summary

If an unknown user from specified hosts quits in Excess flood,
with a 3-5 nick length, the bot will automatically put a ban.

New registry keys:

  • protection.botnet.hosts: the hosts to ban, * allowed
  • protection.botnet.banreason: the ban reason
  • protection.botnet.banduration: the ban duration in minutes

New helper procedures in core:

  • gethost: extracts the host part of a [nick!]user@host string
  • isipv4, isipv6, isip: determines if a string is an ip

Fixes T515.

Test Plan
  • Deploy on Daeghrefn
  • See how it behaves at the next attack

Fixed typo in variable name

[sign:excessflood]: can't read "hot": no such variable

The protection works, but ban duration is in minutes, not in seconds.
