Subject: [PATCH v2] bpf: bpftool: Setting error code in do_loader()
Date: Tue, 11 Mar 2025 12:12:37 +0900 [thread overview]
Message-ID: <20250311031238.14865-1-swnam0729@gmail.com> (raw)
missing error code in do_loader()
bpf_object__open_file() failed, but return 0
This means the command's exit status code was successful, so make sure to return the correct error code.
To maintain consistency with other locations where bpf_object__open_file() is called, it returns -1 instead.

Closes: https://github.com/libbpf/bpftool/issues/156
