From: Ian Rogers <irogers@google.com> stable inclusion from stable-v6.6.33 commit ff9504c045b5cc7c740a0e5515463a13c1b40d99 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 459fee7b508231cd4622b3bd94aaa85e8e16b888 ] bpf_program__attach_uprobe_opts will search LD_LIBRARY_PATH and so specifying `/lib64` is unnecessary and causes failures for libc.so.6 paths like `/lib/x86_64-linux-gnu/libc.so.6`.
