Subject: Use a case-sensitive hash table for ADB address entries
X-Git-Tag: v9.19.1~12^2~1
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c44d7c8034384a284a8df1f57fd2b7d60f505a61;p=thirdparty%2Fbind9.git

Use a case-sensitive hash table for ADB address entries

The key for the ADB `entrybuckets` hash table is a binary `struct
isc_sockaddr` so it seems wrong to use a case-insensitive hash.
