-------------------------------------------------------------------- tcp and udp dialers -------------------------------------------------------------

hex2byte returns the byte slice represented by the hex string s.

Binds a socket to a particular network interface.

Get the internal proxies.

Cannot import pkg core here. from: intra/core/typ.go:isNil

mainRpnProxyFor returns the main (default) RPN proxy from this multi-transport.

realipsFor returns all live primary ips for a given tid+uid pair

track marks a name as being tracked by this client; name is NOT normalized.

trackmap registers snap under id for use in Snapshot(). Returns a deregister function that removes it from the registry.

Alloc16 returns a truncated byte slice of size 16384

Base64 returns the key as a base64-encoded string.

Client returns a client that uses this proxy.

Close closes the connection and the read and write flags.

Cond returns true if the signal has been fired.

Confirm marks ip as the confirmed address. No-op if current confirmed IP is the same as ip. No-op if s is of type Protected and ip isn't in seed addrs

DoIt is like Do but return type is same as func once.

Returns the value of the longest prefix of k in the trie or "".

whether the given msg (ans/query) has a a/aaaa question section

Returns true if any route matches cidr.

IPPorts returns all ip:ports of this server.

IsDNSSECAnswerAuthenticated checks if the DNSSEC authenticated bit is set in the DNS answer.

Net2ProxyID splits network string into proto and pid; proto is the network protocol and pid is the proxy ID. May return empty strings.

NewVolatile returns a new uninitialized Volatile.

Pipe reads data from src to dst, and returns the number of bytes copied. Prefers src.WriteTo(dst) and dst.ReadFrom(src) if available. Otherwise, it us

Probe listens on the local address for ICMP packets sent over UDP. Network must be "udp" or "udp4" or "udp6".

Push adds an element to the ring buffer

Race runs all the functions in fs concurrently and returns the first non-error result. Returned values are the result, the index of the function that

Rand64 returns a random 64-bit hex string (16 chars long).

RefreshProto broadcasts proto change to all active proxies. l3 if left empty, will use last recorded value; same for mtu <= 0.

RegisterAddrs registers IP ports with all dialers for a given hostname. If id is dnsx.Bootstrap, the hostname is "protected" from re-resolutions. host

Resolve resolves hostname to IP addresses, bypassing cache. If resolution fails, entries from the cache are returned, if any.

Signal sets the condition to true and wakes all waiters, if any.

Size returns the size of the public key.

Stream reads data from src in to dst until error, and returns the no. of bytes read. Internally, it bypasses io.ReaderFrom and io.WriterTo but uses io

Returns csv of all routes with values like v for cidr.

Wait implements stack.LinkEndpoint.Wait. It waits for the endpoint to stop reading from its FD.

add one or more IP addresses to the set. The hostname can be a domain name or an IP address.

Adds an IP to the set if it is not present. Must be called under Lock.

emitStack sends stacktrace to console or log. Empty msgs are ignored. Log level (ex: "F ") is prepend to each log line when sent to console.

fillSummary copies non-zero values into out.

Also accounts for prefixes such as CT+ID

maybeReplaceDest replaces the target AddrPort with the IP in res, if res.IP is set and valid.

onFlow calls listener.Flow to determine egress rules and routes; thread-safe.

stopIfExistsLocked stops the transport if it exists, then deletes it from the map.

swapBuffersLocked stamps the count header of the active buffer, sets its draining flag, flips active to the other buffer, and returns the Drain call p

Adds k to the trie. Returns true if k was not already in the trie.

backend.Auto must use remote proxies and never use local (ex: ipn.Exit) ones.

Deletes cidr route. Returns true if cidr was found.

-------------------------------------------------------------------- generic dialer ------------------------------------------------------------------

Disconfirm sets the confirmed address to zeroaddr if the current confirmed address is the provided ip.

Dispose closes all existing FDs.
