Problem
Changes in libbpf result in binaries being generated with relocations in
the STT_SECTION. This is not compatible with clang 11 which is found
on Amazon Linux 2.
Solution
Add
-fno-unwind-tables
to generate binaries which are compatible.More defensive BPF program loading.
Result
Restore compatibility with clang 11
