From 21ee1eb2de40c8377de22a9ff7e65663f245a61c Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Thu, 27 Jun 2024 00:50:56 +0200 Subject: [PATCH] conf: Copy up to MAXDNSRCH - 1 bytes, not MAXDNSRCH Spotted by Coverity just recently. Not that it really matters as MAXDNSRCH always appears to be defined as 1025, while a full domain name can have up to 253 characters: it would be a bit pointless to have a longer search domain.
