Subject: [PATCH] selftests/bpf: fix const qualifier in fexit_bpf2bpf test
Date: Thu, 9 Apr 2026 18:11:01 +0900 [thread overview]
Message-ID: <20260409091101.364091-1-random6.xyz@gmail.com> (raw)
prog_name is an array of const char * strings, so strstr() returns a
pointer into const data.
Store the result in a const char * to avoid discarding the const
qualifier.
With GCC 15 this triggers -Werror=discarded-qualifiers and breaks
the build of tools/testing/selftests/bpf.
