Overview ¶

Package peer checks who is on the other end of a local Unix socket. The kernel reports the peer's user, so a process cannot claim to be someone else the way it could with a token or a header.

Functions ¶

func ConnContext ¶

func ConnContext(ctx context.Context, c net.Conn) context.Context

ConnContext is meant for http.Server.ConnContext. It records the peer when a connection is accepted. If the credentials cannot be read no peer is stored, and every request on that connection is refused.

func Require ¶

func Require(policy Policy, log *slog.Logger, next http.Handler) http.Handler

Require refuses requests from anyone the policy does not allow.

func WithPeer ¶

func WithPeer(ctx context.Context, p Peer) context.Context

WithPeer returns a context carrying p. Tests use it to stand in for a real connection.

Types ¶

type Peer ¶

type Peer struct {
	UID uint32
	PID int32
}

Peer is the process on the other end of the socket.

func From ¶

func From(ctx context.Context) (Peer, bool)

type Policy ¶

type Policy struct {
	UIDs []uint32
}

Policy lists the users allowed in. Root is always allowed.

func (Policy) Allows ¶

func (p Policy) Allows(peer Peer) bool
