Types ¶
type AfterFilter ¶
An AfterFilter represents a socket system call filter after an execution of a system call.
It will only be executed after a system call for a socket that has an entry in internal table. If the filter returns a non-nil error, the system call function returns the non-nil error.
type Cookie ¶
type Cookie uint64
A Cookie represents a 3-tuple of a socket; address family, socket type and protocol number.
func (Cookie) Family ¶
Family returns an address family.
func (Cookie) Protocol ¶
Protocol returns a protocol number.
func (Cookie) Type ¶
Type returns a socket type.
type Filter ¶
type Filter func(*Status) (AfterFilter, error)
A Filter represents a socket system call filter.
It will only be executed before a system call for a socket that has an entry in internal table. If the filter returns a non-nil error, the execution of system call will be canceled and the system call function returns the non-nil error. It can return a non-nil AfterFilter for filtering after the execution of the system call.
type FilterType ¶
type FilterType int
A FilterType represents a filter type.
const ( FilterSocket FilterType = iota // for Socket FilterConnect // for Connect or ConnectEx FilterListen // for Listen FilterAccept // for Accept, Accept4 or AcceptEx FilterGetsockoptInt // for GetsockoptInt FilterClose // for Close or Closesocket )
type Stat ¶
type Stat struct { Family int // address family Type int // socket type Protocol int // protocol number Opened uint64 // number of sockets opened Connected uint64 // number of sockets connected Listened uint64 // number of sockets listened Accepted uint64 // number of sockets accepted Closed uint64 // number of sockets closed OpenFailed uint64 // number of sockets open failed ConnectFailed uint64 // number of sockets connect failed ListenFailed uint64 // number of sockets listen failed AcceptFailed uint64 // number of sockets accept failed CloseFailed uint64 // number of sockets close failed }
A Stat represents a per-cookie socket statistics.
func (Stat) String ¶
type Status ¶
type Status struct { Cookie Cookie Err error // error status of socket system call SocketErr error // error status of socket by SO_ERROR }
A Status represents the status of a socket.
func (Status) String ¶
type Switch ¶
type Switch struct {
// contains filtered or unexported fields
}
A Switch represents a callpath point switch for socket system calls.
func (*Switch) Set ¶
func (sw *Switch) Set(t FilterType, f Filter)
Set deploys the socket system call filter f for the filter type t.
func (*Switch) Sockets ¶
func (sw *Switch) Sockets() Sockets
Sockets returns mappings of socket descriptor to socket status.
func (*Switch) Stats ¶
Stats returns a list of per-cookie socket statistics.
