Subject: [PATCH v2 bpf-next] bpf: Fix an error code in check_btf_func()
Date: Thu, 4 Jun 2020 11:54:36 +0300 [thread overview]
Message-ID: <20200604085436.GA943001@mwanda> (raw)
In-Reply-To: <CAADnVQJPwtan12Htu-0VhvuC3M-o_kbnPpN=SXVC-amn9BcZCw@mail.gmail.com>
This code returns success if the "info_aux" allocation fails but it
should return -ENOMEM.
Fixes: 8c1b6e69dcc1 ("bpf: Compare BTF types of functions arguments with actual types")
