Describe the bug

When using app-elfloader (via the run.sh script in run-app-elfloader) to run the iputils ping dynamic PIE build, ping fails to function correctly.

It seems like this issue is related to how some specific socket options are being handled. Ping needs to use some specific options in order to work but is unable to set them.

Steps to reproduce

Clone run-app-elfloader and dynamic-apps.

Try to ping some ip using the following command:

sudo ./run.sh -n -k app-elfloader_qemu-x86_64 -r ./dynamic-apps/iputils ./bin/ping 8.8.8.8

Expected behavior

The expected output should be showing successful ping messages for example like this:

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=29.0 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=116 time=29.1 ms

Which architectures were you using or does this bug affect?

x86_64

Which platforms were you using or does this bug affect?
