Constants ¶
const ClangEndian = "el"
ClangEndian is set to either "el" or "eb" depending on the host's endianness.
const ( // Version constant used in ELF binaries indicating that the loader needs to // substitute the eBPF program's version with the value of the kernel's // KERNEL_VERSION compile-time macro. Used for compatibility with BCC, gobpf // and RedSift. MagicKernelVersion = 0xFFFFFFFE )
Variables ¶
var NativeEndian binary.ByteOrder = binary.LittleEndian
NativeEndian is set to either binary.BigEndian or binary.LittleEndian, depending on the host's endianness.
Functions ¶
func Htons ¶
Htons converts the unsigned short integer hostshort from host byte order to network byte order.
func KernelRelease ¶
KernelRelease returns the release string of the running kernel. Its format depends on the Linux distribution and corresponds to directory names in /lib/modules by convention. Some examples are 5.15.17-1-lts and 4.19.0-16-amd64.
func OpenRawSock ¶
Types ¶
type SafeELFFile ¶
func NewSafeELFFile ¶
func NewSafeELFFile(r io.ReaderAt) (safe *SafeELFFile, err error)
NewSafeELFFile reads an ELF safely.
Any panic during parsing is turned into an error. This is necessary since there are a bunch of unfixed bugs in debug/elf.

func OpenSafeELFFile ¶
func OpenSafeELFFile(path string) (safe *SafeELFFile, err error)
OpenSafeELFFile reads an ELF from a file.
It works like NewSafeELFFile, with the exception that safe.Close will close the underlying file.
func (*SafeELFFile) DynamicSymbols ¶
func (se *SafeELFFile) DynamicSymbols() (syms []elf.Symbol, err error)
DynamicSymbols is the safe version of elf.File.DynamicSymbols.
func (*SafeELFFile) SectionsByType ¶
func (se *SafeELFFile) SectionsByType(typ elf.SectionType) []*elf.Section
SectionsByType returns all sections in the file with the specified section type.
type Version ¶
type Version [3]uint16
A Version in the form Major.Minor.Patch.
func KernelVersion ¶
KernelVersion returns the version of the currently running kernel.
func NewVersion ¶
NewVersion creates a version from a string like "Major.Minor.Patch".
Patch is optional.
func NewVersionFromCode ¶
NewVersionFromCode creates a version from a LINUX_VERSION_CODE.
func (Version) Kernel ¶
Kernel implements the kernel's KERNEL_VERSION macro from linux/version.h. It represents the kernel version and patch level as a single value.
func (Version) Unspecified ¶
Unspecified returns true if the version is all zero.
