Overview

Package syserr contains sandbox-internal errors. These errors are distinct from both the errors returned by host system calls and the errors returned to sandboxed applications.

TODO(b/34162363): Remove or replace most of these errors.

Some of the errors should be replaced with package specific errors and others should be removed entirely.

Note that some errors are declared in platform-specific files.

Functions

This section is empty.

Types

type Error

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

Error represents an internal error.

func FromError

func FromError(err error) *Error

FromError converts a generic error to an *Error.

TODO(b/34162363): Remove this function.

func FromHost

func FromHost(err unix.Errno) *Error

FromHost translates a unix.Errno to a corresponding Error value.

func New

func New(message string, linuxTranslation errno.Errno) *Error

New creates a new Error and adds a translation for it.

New must only be called at init.

func NewDynamic

func NewDynamic(message string, linuxTranslation errno.Errno) *Error

NewDynamic creates a new error with a dynamic error message and an errno translation.

NewDynamic should only be used sparingly and not be used for static error messages. Errors with static error messages should be declared with New as global variables.

func TranslateNetstackError

func TranslateNetstackError(err tcpip.Error) *Error

TranslateNetstackError converts an error from the tcpip package to a sentry internal error.

func (*Error) String

func (e *Error) String() string

String implements fmt.Stringer.String.

func (*Error) ToError

func (e *Error) ToError() error

ToError translates an Error to a corresponding error value.

TODO(b/34162363): Remove this.

func (*Error) ToLinux

func (e *Error) ToLinux() errno.Errno

ToLinux converts the Error to a Linux ABI error that can be returned to the application.
