[Benjamin Nilsen <bcnilsen@xxxxxxxxxxx>]

Hello,

I believe I found some bugs with libbpf and just wanted to share them here.
I have attached them below.

Regards,
Ben


The first one:
I believe there is an error with: libbpf_nla_dump_errormsg();

The second one:
libbpf_nla_parse();

Third one:
I believe there is a stack buffer overflow with the method
bpf_object__open_buffer() when running the attached program with the
input:
./LibbpfTest15.c (executable version) LibbpfTest15buginput LibbpfTest15buginput
