Subject: [PATCH bpf,v2,0/2] bpf: fix incorrect name check pass logic in btf_name_valid_section

This patch was written to fix an issue where btf_name_valid_section() would 
not properly check names with certain conditions and would throw an OOB vuln. 
And selftest was added to verify this patch.

Jeongjun Park (2):
  bpf: add check for invalid name in btf_name_valid_section()
  selftest/bpf : Add a selftest test case to check for incorrect names
