Functions ¶
func ClockTicksToNsSinceBootTime ¶ added in v0.18.0
ClockTicksToNsSinceBootTime converts kernel clock ticks to nanoseconds.
func CopyRegularFileByPath ¶ added in v0.8.2
CopyRegularFileByPath copies a file from src to dst
func CopyRegularFileByRelativePath ¶ added in v0.8.2
CopyRegularFileByRelativePath copies a file from src to dst, where destination is relative to a given directory. This function needs needed capabilities to be set before it is called.
func CreateAt ¶ added in v0.8.2
CreateAt implements the same logic as os.Create using directory FD and relative path.
func GenerateRandomDuration ¶ added in v0.18.0
GenerateRandomDuration returns a random duration between min and max, inclusive
func GetBootTime ¶ added in v0.18.0
GetBootTime returns the boot time of the system in time.Time format.
func GetBootTimeNS ¶ added in v0.18.0
func GetBootTimeNS() int64
GetBootTimeNS returns the boot time of the system in nanoseconds.
func GetStartTimeNS ¶ added in v0.18.0
func GetStartTimeNS() int64
GetStartTimeNS returns the system start time in nanoseconds (using CLOCK_MONOTONIC).
func GetSystemHZ ¶ added in v0.18.0
func GetSystemHZ() int
GetSystemHZ returns an approximation of CONFIG_HZ (the kernel timer interrupt).
func GetUserHZ ¶ added in v0.18.0
func GetUserHZ() int64
GetUserHZ returns USER_HZ (the user-space timer interrupt), the system clock tick rate.
func HashTaskID ¶ added in v0.18.0
func HashU32AndU64 ¶ added in v0.18.0
HashU32AndU64 is a wrapper around Murmur32 making sure network byte order is used.
func IsDirEmpty ¶ added in v0.10.0
IsDirEmpty returns true if directory contains no files
func MkdirAt ¶ added in v0.8.2
MkdirAt is a wrapper function to the `mkdirat` syscall using golang types.
func MkdirAtExist ¶ added in v0.8.2
MkdirAtExist is a wrapper function to the `mkdirat` syscall using golang types, ignoring EEXIST error.
func NsSinceBootTimeToTime ¶ added in v0.18.0
NsSinceBootTimeToTime converts nanoseconds timestamp (since boot) to a time.Time object.
func OpenAt ¶ added in v0.8.2
OpenAt is a wrapper function to the `openat` syscall using golang types.
func OpenExistingDir ¶ added in v0.8.2
OpenExistingDir open a directory with given path, and return the os.File of it.
func ParseSymbol ¶
func ParseSymbol(address uint64, table *helpers.KernelSymbolTable) helpers.KernelSymbol
func RemoveAt ¶ added in v0.14.1
RemoveAt is a wrapper function to the `unlinkat` syscall using golang types.
func RenameAt ¶ added in v0.8.2
RenameAt is a wrapper function to the `renameat` syscall using golang types.
func RoundToClosestN ¶ added in v0.18.0
RoundToClosestN rounds a number to the closest multiple of n.
