Functions

func AddToDebugInfo

func AddToDebugInfo(di *debug.Info)

AddToDebugInfo adds compatibility data to the given debug.Info.

func GetIPTablesChains

func GetIPTablesChains() ([]string, error)

GetIPTablesChains returns the chain names currently in ip(6)tables.

func ReportMultiPeerUDPTunnelIssue

func ReportMultiPeerUDPTunnelIssue(p *process.Process)

ReportMultiPeerUDPTunnelIssue reports a multi-peer UDP tunnel for the given process.

func ReportSecureDNSBypassIssue

func ReportSecureDNSBypassIssue(p *process.Process)

ReportSecureDNSBypassIssue reports a DNS bypassing issue for the given process.

func SelfCheckIsFailing

func SelfCheckIsFailing() bool
