-/* This file contains the definition of the kernel helpers that are
- available to eBPF programs.
-
- The primary source for information on kernel helpers is the
- linux/include/uapi/linux/bpf.h file in the Linux source tree.
- Please keep this database in sync.
-
- The first column is the first kernel version featuring the helper
- function. This should be an enumerate from bpf_kernel_version,
- defined in bpf-opts.h. Note that the backend assumes that helpers
- never get deprecated in the kernel. If that eventually happens,
- then we will need to use a bitmask here instead of an enumerate.
-
- The second column is the constant-name for the helper.
- The third column is the program-name of the helper.
-
- The fourth column is a list of names describing the types of the
- values returned and accepted by the helper, in one of these forms:
-
- TYPES (type1, type2, ..., 0)
- VTYPES (type1, type2, ..., 0)
-
- VTYPES should be used should the helper accept a variable number of
- arguments, TYPES otherwise. The valid type names are:
-
- `vt' for void.
- `it' for signed int.
- `ut' for unsigned int.
- `pt' for void*.
- `cpt' for const void*.
- `st' for short int.
- `ust' for unsigned short int.
- `cst' for const char *.
- `ullt' for unsigned long long.
- `llt' for long long.
- `u32t' for uint32.
- `u64t' for uint64.
-
- In types descriptions, the firt entry corresponds to the value
- returned by the helper. Subsequent names correspond to the helper
- arguments. Finally, a 0 should close the list.
-
- VERY IMPORTANT: the helper entries should be listed in the same
- order than in the definition of __BPF_FUNC_MAPPER in
- linux/include/uapi/linux/bpf.h! */

-@subsection BPF Kernel Helpers
-
-These built-in functions are available for calling kernel helpers, and
-they are available depending on the kernel version selected as the
-CPU.
-
-Rather than using the built-ins directly, it is preferred for programs
-to include @file{bpf-helpers.h} and use the wrappers defined there.
-
-For a full description of what the helpers do, the arguments they
-take, and the returned value, see the
-@file{linux/include/uapi/linux/bpf.h} in a Linux source tree.
