Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Remove tst_run from lwt_seg6local_prog_ops.
The syzbot reported that the lwt_seg6 related BPF ops can be invoked
via bpf_test_run() without without entering input_action_end_bpf()
first.
Martin KaFai Lau said that self test for BPF_PROG_TYPE_LWT_SEG6LOCAL
probably didn't work since it was introduced in commit 04d4b274e2a
("ipv6: sr: Add seg6local action End.BPF"). The reason is that the
per-CPU variable seg6_bpf_srh_states::srh is never assigned in the self
test case but each BPF function expects it.
Remove test_run for BPF_PROG_TYPE_LWT_SEG6LOCAL.
