Functions

func GetExecUIDGIDFromUser

func GetExecUIDGIDFromUser(ctx context.Context, vmns *vfs.MountNamespace, user string) (auth.KUID, auth.KGID, error)

GetExecUIDGIDFromUser retrieves the UID and GID from /etc/passwd file for the given user.

func MaybeAddExecUserHome

func MaybeAddExecUserHome(ctx context.Context, vmns *vfs.MountNamespace, uid auth.KUID, envv []string) ([]string, error)

MaybeAddExecUserHome returns a new slice with the HOME environment variable set if the slice does not already contain it, otherwise it returns the original slice unmodified.

func ResolveExecutablePath

func ResolveExecutablePath(ctx context.Context, args *kernel.CreateProcessArgs) (string, error)

ResolveExecutablePath resolves the given executable name given the working dir and environment. Returns *ExecutableResolveError when the executable cannot be resolved.

Types

type ExecutableResolveError

type ExecutableResolveError struct {
	// contains filtered or unexported fields
}

ExecutableResolveError represents a failure to resolve the executable in ResolveExecutablePath.
