Many conditional checks in switch-case are redundant with bpf_base_func_proto and should be removed. Regarding the permission checks bpf_base_func_proto: The permission checks in bpf_prog_load (as outlined below) ensure that the trace has both CAP_BPF and CAP_PERFMON capabilities, thus enabling the use of corresponding prototypes in bpf_base_func_proto without adverse effects. bpf_prog_load ...... bpf_cap = bpf_token_capable(token, CAP_BPF); ...... if (type != BPF_PROG_TYPE_SOCKET_FILTER && type != BPF_PROG_TYPE_CGROUP_SKB && !bpf_cap) goto put_token; ...... if (is_perfmon_prog_type(type) && !bpf_token_capable(token, CAP_PERFMON)) goto put_token; ......

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
