David Anderson	1fdadf06f1	testy: don't give Clock.Step==0 magical behavior. Turns out it's sometimes useful to stop time entirely. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	8b3f6be008	control/controlclient: flip IPv6 to be on by default The DEBUG_INCLUDE_IPV6 environment variable is now an opt-out. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	322499473e	cmd/tailscaled, wgengine, ipn: add /debug/ipn handler with world state Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	dbca186a64	stunner: fix data race. In very low-latency conditions, a STUN request can complete before the startup loop has finished firing off goroutines, leading to a concurrent map mutation.	5 years ago
Brad Fitzpatrick	7fb8d873ac	logpolicy: don't log timestamp when running under systemd It'll do it anyway. Makes journalctl -fu cleaner. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	2d48f92a82	wgengine/magicsock: re-stun every [20,27] sec, not 28 28 is cutting it close, and we think jitter will help some spikes we're seeing. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	2c7ddd0828	go.mod, go.sum: tidy	5 years ago
Brad Fitzpatrick	577f321c38	wgengine/magicsock: revise derp fallback logic Revision to earlier `6284454ae5` Don't be sticky if we have no peers. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	cbd8aceb95	go.mod: bump wireguard-go version. Fixes #219. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	2e420ad8b6	wgengine, wgengine/filter: minor doc, style, performance, locking changes Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	6284454ae5	wgengine/magicsock: if UDP blocked, pick DERP where most peers are Updates #207 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Avery Pennarun	f53e78e0d5	wgengine: don't lose filter state on filter reconfig. We were abandoning the UDP port LRU every time we got a new packet filter from tailcontrol, which caused return packets to suddenly stop arriving.	5 years ago
Avery Pennarun	4336de0d98	ipn/local: don't print packet filter every single time. It's extremely noisy right now for domains with complex ACLs.	5 years ago
Avery Pennarun	a56e853b72	cmd/relaynode: delete it! tailscale+tailscaled now completely obsoletes relaynode, so let's let it finally go away.	5 years ago
David Anderson	73fccd8b06	control/controlclient: remove old compat PacketFilter initialization. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	d321190578	wgengine/magicsock: stringify [IPv6]:port normally in AddrSet.String	5 years ago
Brad Fitzpatrick	3c3ea8bc8a	wgengine/magicsock: finish IPv6 transport support DEBUG_INCLUDE_IPV6=1 is still required, but works now. Updates #18 (fixes it, once env var gate is removed)	5 years ago
Brad Fitzpatrick	82ed7e527e	wgengine/magicsock: remove log allocation This was the whole point but I goofed at the last line.	5 years ago
Brad Fitzpatrick	8454bbbda5	wgengine/magicsock: more logging improvements * remove endpoint discovery noise when results unchanged * consistently spell derp nodes as "derp-N" * replace "127.3.3.40:" with "derp-" in CreateEndpoint log output * stop early DERP setup before SetPrivateKey is called; it just generates log nosie * fix stringification of peer ShortStrings (it had an old %x on it, rendering it garbage) * describe why derp routes are changing, with one of: shared home, their home, our home, alt	5 years ago
Brad Fitzpatrick	64aff0db7b	control/controlclient: add TODO to delete the UAPI method	5 years ago
Brad Fitzpatrick	7740cbd8d9	ipn: call SetNetInfoCallback later, in Start It was being called back into ultimately from magicsock before there was a control client. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	680311b3df	wgengine/magicsock: fix few remaining logs without package prefix	5 years ago
Brad Fitzpatrick	c473927558	wgengine/magicsock: clean up, add, improve DERP logs	5 years ago
Brad Fitzpatrick	e749377a56	derp/derphttp: remove a redundant log message	5 years ago
Brad Fitzpatrick	1d3f45f9be	derp/derphttp: ignore PeerGoneMessage in test	5 years ago
Brad Fitzpatrick	ea9310403d	wgengine/magicsock: re-STUN on DERP connection death Fixes #201	5 years ago
Brad Fitzpatrick	1ab5b31c4b	derp, magicsock: send new "peer gone" frames when previous sender disconnects Updates #150 (not yet enabled by default in magicsock) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Crawshaw	e60b433831	tailcfg: NetInfo.String: handle nil object without panicing Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	b6f77cc48d	wgengine/magicsock: return early, outdent in derpWriteChanOfAddr	5 years ago
Brad Fitzpatrick	8c4cef60f8	derp: wait for send goroutine to finish before returning from run I saw a test flake due to the sender goroutine logging (ultimately to t.Logf) after the server was closed. This makes sure the all goroutines are cleaned up before Server.Close returns.	5 years ago
Brad Fitzpatrick	521ad7b0fc	derp: only flush writes to clients when we're out of things to write Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	0a25abcdaa	derp: remove TODO comment It was done in `bf704a5218`	5 years ago
Brad Fitzpatrick	8519a1b29f	derp: revert rename of pkt to sendMsg New plan, sorry. Most reverts `77921a31b1`, except some doc changes.	5 years ago
Brad Fitzpatrick	c34b350efa	derp: remove the mutex around and closing of send channel Makes it less complicated. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	77921a31b1	derp: rename pkt to sendMsg, in prep for other types of writes Updates #150	5 years ago
Brad Fitzpatrick	1453aecb44	derp: add sclient.done channel, simplify some context passing This is mostly prep for a few future CLs, making sure we always have a close-on-dead done channel available to select on when doing other channel operations.	5 years ago
David Anderson	ea90780066	derp: specify type of the by-reason drop varz. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	fd824df1fa	derp: export metric for server's initial MemStats.Sys reading Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	64b5248929	derp: sprinkle comments and docstrings. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	58b8ebd290	derp: add per-reason packet drop counter. In parallel with the summed counter for now, for dashboard migration. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	1e031001db	derp: move write timeout to package constant. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	dbfc916273	derp: add short queues between reader and writer, drop on overload. This avoids the server blocking on misbehaving or heavily contended clients. We attempt to drop from the head of the queue to keep overall queueing time lower. Also: - fixes server->client keepalives, which weren't happening. - removes read rate-limiter, deferring instead to kernel-level global limiter/fair queuer. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	dd31285ad4	wgengine/magicsock: send IPv6 using pconn6, if available In prep for IPv6 support. Nothing should make it this far yet.	5 years ago
Brad Fitzpatrick	af277a6762	controlclient, magicsock: add debug knob to request IPv6 endpoints Add opt-in method to request IPv6 endpoints from the control plane. For now they should just be skipped. A previous version of this CL was unconditional and reportedly had problems that I can't reproduce. So make it a knob until the mystery is solved. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	221e7d7767	wgengine/magicsock: make log message include DERP port (node)	5 years ago
Brad Fitzpatrick	33bdcabf03	wgengine/magicsock: call stun callback w/ only valid part of STUN packet	5 years ago
David Crawshaw	13eed1e88b	controlclient: remove common log on very quiet nodes Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	f9cc4e8f53	tailcfg: restore MapRequest.IncludeIPv6 bool Partially restores `0be475ba46`	5 years ago
David Anderson	0be475ba46	Revert "tailcfg, controlclient, magicsock: request IPv6 endpoints, but ignore them" Breaks something deep in wireguard or magicsock's brainstem, no packets at all can flow. All received packets fail decryption with "invalid mac1". This reverts commit `94024355ed`. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	f9184ad12b	go.mod: update wireguard-go for https://github.com/tailscale/wireguard-go/pull/13	5 years ago
