Bug ID: 28928
Summary: Wrong dynamic section entry number
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: dichen at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
when using `$ eu-readelf -d {file}` to get the number of dynamic section
entris,
It wrongly counts the padding DT_NULLs as dynamic section entries.
However, DT_NULL Marks end of dynamic section. They should not be counted as
dynamic section entries.
```
$ eu-readelf -d /usr/local/bin/eu-readelf
Dynamic segment contains 31 entries:
