Functions ¶
func AppendPrefixMask ¶
AppendPrefixMask appends a prefix mask to a v4 or v6 address and returns the result as a string.
func CheckPeriodically ¶
func CheckPeriodically(ctx context.Context, duration time.Duration, fn func() (bool, error)) (bool, error)
CheckPeriodically checks a function (fn) at a specified interval (duration). It will return when one of these conditions occurs: fn returns true, fn returns an error, the duration is met, or the context is Done().
func ContainsValidCustomIPv4Ranges ¶
ContainsValidCustomIPv4Ranges matches the following custom IPv4 patterns usable by netfilter userspace utils: Cidr notation 100.100.0.0/16 Individual address 10.100.0.2 Dash-separated range 100.100.0.0-100.100.10.255
func ContainsValidCustomIPv6Ranges ¶
ContainsValidCustomIPv6Ranges matches the following custom IPv6 patterns usable by netfilter userspace utils: Cidr notation 200::/64 Individual address 200::2 Dash-separated range 200::1-200::8 Dash-separated range 2001:0db8:0000:0000:0000:0000:0000:0000-2001:0db8:ffff:ffff:ffff:ffff:ffff:ffff
func FilterOutAllowed ¶
func GoWithWaitGroup ¶
GoWithWaitGroup runs fn in a goroutine with an optional *sync.WaitGroup to track when fn finishes executing.
func IPNetSliceToStringSlice ¶
func IgnoreError ¶
func IgnoreError(fn fnWithErrorResult)
IgnoreError call the passed fn and ignore the errors it returns. Example `defer util.IgnoreError(file.Close)`
func IsDefaultIPRoute ¶
IsDefaultIPRoute wrapper for IsDefaultIPv4Route and IsDefaultIPv6Route
func IsDefaultIPv4Route ¶
IsDefaultIPv4Route checks if the given prefix is the default route for IPv4.
func IsDefaultIPv6Route ¶
IsDefaultIPv6Route checks if the given prefix is the default route for IPv6.
func IsIPv4Address ¶
IsIPv4Address checks if the given IP address is an IPv4 address.
func IsIPv4Prefix ¶
IsIPv4Prefix checks if the given IP address is an IPv4 prefix.
func IsIPv6Address ¶
IsIPv6Address checks if the given IP address is an IPv6 address.
func IsIPv6Prefix ¶
IsIPv6Prefix checks if the given IP address is an IPv6 prefix.
func IsValidPrefix ¶
IsValidPrefix checks if the given cidr is valid
func JsonStringer ¶
func JsonUnmarshal ¶
func MustJsonMarshalToString ¶
func MustJsonMarshalToString(x interface{}) string
func ParseTime ¶
ParseTime attempts to parse a time string in three possible formats to handle UTC and local time differences between Darwin and Linux and the proxy mode. On each system we get different time formats for the last wireguard handshake time.
func RetryOperation ¶
func RetryOperation(ctx context.Context, wait time.Duration, retries int, operation func() error) error
RetryOperation retries the operation with a backoff policy.
func RetryOperationExpBackoff ¶
func RetryOperationExpBackoff(ctx context.Context, maxWait time.Duration, operation func() error) error
RetryOperationExpBackoff retries the operation with an exponential backoff policy.
func RetryOperationForErrors ¶
func RetryOperationForErrors(ctx context.Context, wait time.Duration, retries int, retriableErrors []error, operation func() error) error
RetryOperationForErrors retries the operation with a backoff policy for the specified errors, otherwise will just perform the operation once and return the error if it fails.
func SplitKeyValue ¶
func StringToInt64 ¶
func TimeBeginPeriod ¶
func TimeEndPeriod ¶
func ValidateIPv4Cidr ¶
ValidateIPv4Cidr checks for a valid IPv4 cidr
func ValidateIPv6Cidr ¶
ValidateIPv6Cidr checks for a valid IPv6 cidr
func WithTrace ¶
func WithTrace(ctx context.Context, l *zap.SugaredLogger) *zap.SugaredLogger
