Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago
Brad Fitzpatrick	9b8ca219a1	wgengine/magicsock: remove allocs in UDP write, use new netaddr.PutUDPAddr The allocs were only introduced yesterday with a TODO. Now they're gone again.	4 years ago
Brad Fitzpatrick	7b3c0bb7f6	wgengine/magicsock: fix crash reading DERP packet Starting at yesterday's `e96f22e560` (convering some UDPAddrs to IPPorts), Conn.ReceiveIPv4 could return a nil addr, which would make its way through wireguard-go and blow up later. The DERP read path wasn't initializing the addr result parameter any more, and wgRecvAddr wasn't checking it either. Fixes #515	4 years ago
Brad Fitzpatrick	47b4a19786	wgengine/magicsock: use netaddr.ParseIPPort instead of net.ResolveUDPAddr	4 years ago
Brad Fitzpatrick	f7124c7f06	wgengine/magicsock: start of discoEndpoint state tracking Updates #483	4 years ago
Brad Fitzpatrick	92252b0988	wgengine/magicsock: add a little LRU cache for netaddr.IPPort lookups And while plumbing, a bit of discovery work I'll need: the endpointOfAddr map to map from validated paths to the discoEndpoint. Not being populated yet. Updates #483	4 years ago
Brad Fitzpatrick	2d6e84e19e	net/netcheck, wgengine/magicsock: replace more UDPAddr with netaddr.IPPort	4 years ago
Brad Fitzpatrick	9070aacdee	wgengine/magicsock: minor comments & logging & TODO changes	4 years ago
Brad Fitzpatrick	e96f22e560	wgengine/magicsock: start handling disco message, use netaddr.IPPort more Updates #483	4 years ago
Brad Fitzpatrick	790ef2bc5f	internal/deepprint: update copyright header to appease license checker script Plus mention that it's not an exact copy.	4 years ago
Brad Fitzpatrick	eb4eb34f37	disco: new package for parsing & marshaling discovery messages Updates #483	4 years ago
Brad Fitzpatrick	7ca911a5c6	internal/deepprint: add missing copyright headers	4 years ago
Brad Fitzpatrick	a83ca9e734	wgengine/magicsock: cache precomputed nacl/box shared keys Updates #483	4 years ago
Brad Fitzpatrick	a975e86bb8	wgengine/magicsock: add new endpoint type used for discovery-supporting peers This adds a new magicsock endpoint type only used when both sides support discovery (that is, are advertising a discovery key). Otherwise the old code is used. So far the new code only communicates over DERP as proof that the new code paths are wired up. None of the actually discovery messaging is implemented yet. Support for discovery (generating and advertising a key) are still behind an environment variable for now. Updates #483	4 years ago
Brad Fitzpatrick	72bfea2ece	control/controlclient: remove IPv6 opt-out environment variable It was temporary and 3 months has elapsed without problems.	4 years ago
Brad Fitzpatrick	6f73f2c15a	wgengine, internal/deepprint: replace UAPI usage as hash func; add deepprint The new deepprint package just walks a Go data structure and writes to an io.Writer. It's not pretty like go-spew, etc. We then use it to replace the use of UAPI (which we have a TODO to remove) to generate signatures of data structures to detect whether anything changed (without retaining the old copy). This was necessary because the UAPI conversion ends up trying to do DNS lookups which an upcoming change depends on not happening.	4 years ago
Brad Fitzpatrick	103c06cc68	wgengine/magicsock: open discovery naclbox messages from known peers And track known peers. Doesn't yet do anything with the messages. (nor does it send any yet) Start of docs on the message format. More will come in subsequent changes. Updates #483	4 years ago
David Crawshaw	9258d64261	wgengine/router: do not call ifconfig up if SetRoutesFunc is set The NetworkExtension brings up the interface itself and does not have access to `ifconfig`, which the underlying BSD userspace router attempts to use when Up is called. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
Brad Fitzpatrick	23e74a0f7a	wgengine, magicsock, tstun: don't regularly STUN when idle (mobile only for now) If there's been 5 minutes of inactivity, stop doing STUN lookups. That means NAT mappings will expire, but they can resume later when there's activity again. We'll do this for all platforms later. Updates tailscale/corp#320 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	fe50cd0c48	ipn, wgengine: plumb NetworkMap down to magicsock Now we can have magicsock make decisions based on tailcfg.Debug settings sent by the server. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	b8edb7a5e9	control/controlclient: add Debug field to NetworkMap As part of disabling background STUN packets when idle, we want an emergency override switch to turn it back on, in case it interacts poorly in the wild. We'll send that via control, but we'll want to plumb it down to magicsock via NetworkMap. Updates tailscale/corp#320 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	0071888a17	types/opt: add Bool.EqualBool method Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	4732722b87	derp: add frameClosePeer to move around clients within a region For various reasons (mostly during rollouts or config changes on our side), nodes may end up connecting to a fallback DERP node in a region, rather than the primary one we tell them about in the DERP map. Connecting to the "wrong" node is fine, but it's in our best interest for all nodes in a domain to connect to the same node, to reduce intra-region packet forwarding. This adds a privileged frame type used by the control system that can kick off a client connection when they're connected to the wrong node in a region. Then they hopefully reconnect immediately to the correct location. (If not, we can leave them alone and stop closing them.) Updates tailscale/corp#372	4 years ago
Brad Fitzpatrick	dd43d9bc5f	derp: fix varz typo Updates tailscale/corp#391	4 years ago
Brad Fitzpatrick	3553512a71	cmd/derper: fix embarassing bug introduced in earlier refactor The remove hook implementation was copy/pasted from the line above and I didn't change the body, resulting in packet forwarding routes never being removed. Fortunately we weren't using this path yet, but it led to stats being off, and (very) slow memory growth.	4 years ago

Brian Chu	2a8e064705	cmd/tailscale: Allow advertising subnet routes on *BSD. Use sysctl to check IP forwarding state for better OS compatiblity. Signed-off-by: Brian Chu <cynix@cynix.org>	4 years ago
Reinaldo de Souza	a8635784bc	wgengine: add BSD userspace router to darwin Darwin and FreeBSD are compatible enough to share the userspace router. The OSX router delegates to the BSD userspace router unless `SetRoutesFunc` is set. That preserves the mechanism that allows `ipn-go-bridge` to specify its own routing behavior. Fixes #177 Signed-off-by: Reinaldo de Souza <github@rei.nal.do>	4 years ago
Brad Fitzpatrick	b87396b5d9	cmd/derper, derp: add some more varz and consistency check handler I'm trying to hunt down a slow drift in numbers not agreeing.	4 years ago

Brad Fitzpatrick	666d404066	ipn: put discovery key generation behind an environment flag for now Later we'll want to use the presence of a discovery key as a signal that the node knows how to participate in discovery. Currently the code generates keys and sends them to the control server but doesn't do anything with them, which is a bad state to stay in lest we release this code and end up with nodes in the future that look like they're functional with the new discovery protocol but aren't. So for now, make this opt-in as a debug option for now, until the rest of it is in. Updates #483	4 years ago
