Subject: [PATCH bpf-next v1 0/6] Typeless/weak ksym for gen_loader + misc fixups
Date: Wed, 6 Oct 2021 05:58:47 +0530 [thread overview]
Message-ID: <20211006002853.308945-1-memxor@gmail.com> (raw)
Patches (1,2,4) add typeless and weak ksym support to gen_loader. It is follow
up for the recent kfunc from modules series.
The later patches (5,6) are misc fixes for selftests, and patch 3 for libbpf
where we try to be careful to not end up with mod_btf->fd set as 0 (as that
leads to a confusing error message about btf_id not being found on load and it
is not clear what went wrong, instead we can just dup fd 0).
Kumar Kartikeya Dwivedi (6):
bpf: Add bpf_kallsyms_lookup_name helper
libbpf: Add typeless and weak ksym support to gen_loader
libbpf: Ensure that module BTF fd is never 0
bpf: selftests: Move test_ksyms_weak test to lskel, add libbpf test
bpf: selftests: Fix fd cleanup in sk_lookup test
bpf: selftests: Fix memory leak in test_ima
