Subject: "bpf: Improve the info.func_info and info.func_info_rec_size behavior" breaks strace self tests
Date: Thu, 3 Jan 2019 12:46:13 +0100 [thread overview]
Message-ID: <20190103114613.GB3957@osiris> (raw)
Hello,
the kernel commit 7337224fc150 ("bpf: Improve the info.func_info and
info.func_info_rec_size behavior") breaks one of strace's self tests:
FAIL: bpf-obj_get_info_by_fd-prog-v.gen
Looking into the kernel commit, it seems that the user space visible
uapi change is intentional; even though it might break existing user
space.
To reproduce:
git clone https://gitlab.com/strace/strace.git
cd strace
./bootstrap
./configure
make -j $(nproc)
cd tests
make -j $(nproc) check
