From d2b997c7172e9a00895a9deb379f8782fbd2e36f Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Wed, 30 Dec 2020 23:40:14 +0000 Subject: elf: Fix a DTV setup issue [BZ #27136] The max modid is a valid index in the dtv, it should not be skipped. The bug is observable if the last module has modid == 64 and its generation is same or less than the max generation of the previous modules. Then dtv[0].counter implies dtv[64] is initialized but it isn't. Fixes bug 27136.
