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.
