Log Message:

• (bug 7883) Added autoblock whitelisting feature, using which specific ranges can be protected from autoblocking. These ranges are specified, in list format, in the autoblock_whitelist system message.

. . .

    function doAutoblock( $autoblockip ) {

. . .

•           $ip = wfGetIp();
  

. . .

•                   # Is the IP in this range?
  

•                   if (wfIsAddressInRange( $ip, $wlEntry )) {
  

Um, I'm pretty tired, but shouldn't you be checking against $autoblockip, not wfGetIp()? The IP of the current request is going to be the blocker, at least on retroactive autoblocks.
