Subject: [PATCH bpf,v2,0/2] bpf: fix incorrect name check pass logic in btf_name_valid_section
Date: Sat, 31 Aug 2024 14:45:25 +0900 [thread overview]
Message-ID: <20240831054525.364353-1-aha310510@gmail.com> (raw)
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
