Revision: 371
Committed: Tue Jan 10 10:45:48 2006 UTC (18 years, 2 months ago) by michael
Content type: text/x-chdr
File size: 5639 byte(s)
Log Message:
- Imported recent channelban changes from HEAD which have been tested extensively.
  The match_cidr() fix didn't work in the first try, so I'm not going to bother
  with further debugging.
- Removed match_cidr() and comp_with_mask()
