Artem Savkov 65a903edb8 bpf: Disallow BPF_LOG_KERNEL log level for bpf(BPF_BTF_LOAD) 
Bugzilla: https://bugzilla.redhat.com/2069046

Upstream Status: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

commit 866de407444398bc8140ea70de1dba5f91cc34ac
Author: Hou Tao <houtao1@huawei.com>
Date:   Fri Dec 3 13:30:01 2021 +0800

    bpf: Disallow BPF_LOG_KERNEL log level for bpf(BPF_BTF_LOAD)

    BPF_LOG_KERNEL is only used internally, so disallow bpf_btf_load()
    to set log level as BPF_LOG_KERNEL. The same checking has already
    been done in bpf_check(), so factor out a helper to check the
    validity of log attributes and use it in both places.

    Fixes: 8580ac9404 ("bpf: Process in-kernel BTF")
