Functions

func CheckKernelVersion

func CheckKernelVersion(k, major, minor int) bool

CheckKernelVersion checks if current kernel is newer than (or equal to) the given version.

func CompareKernelVersion

func CompareKernelVersion(a, b VersionInfo) int

CompareKernelVersion compares two kernel.VersionInfo structs. Returns -1 if a < b, 0 if a == b, 1 it a > b

Types

type Utsname

type Utsname syscall.Utsname

Utsname represents the system name structure. It is passthrough for syscall.Utsname in order to make it portable with other platforms where it is not available.

type VersionInfo

type VersionInfo struct {
	Kernel int    // Version of the kernel (e.g. 4.1.2-generic -> 4)
	Major  int    // Major part of the kernel version (e.g. 4.1.2-generic -> 1)
	Minor  int    // Minor part of the kernel version (e.g. 4.1.2-generic -> 2)
	Flavor string // Flavor of the kernel version (e.g. 4.1.2-generic -> generic)
}

VersionInfo holds information about the kernel.

func GetKernelVersion

func GetKernelVersion() (*VersionInfo, error)

GetKernelVersion gets the current kernel version.

func ParseRelease

func ParseRelease(release string) (*VersionInfo, error)

ParseRelease parses a string and creates a VersionInfo based on it.

func (*VersionInfo) String

func (k *VersionInfo) String() string
