/* This file contains the definition of the helpers that are available
|
|
to BPF 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! */
