Subject: [PATCH v1 1/2] perf bench uprobe: Remove lib64 from libc.so.6 binary path
Date: Fri,  5 Apr 2024 21:09:10 -0700	[thread overview]
Message-ID: <20240406040911.1603801-1-irogers@google.com> (raw)

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`.

Fixes: 7b47623b8cae ("perf bench uprobe trace_printk: Add entry attaching an BPF program that does a trace_printk")
