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.

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
Brad Fitzpatrick	94024355ed	tailcfg, controlclient, magicsock: request IPv6 endpoints, but ignore them Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	12a6626a94	tsweb: use a ResponseWriter wrapper to log more accurately. Also adds tests, because the logging handler is acquiring a fair number of branches. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	2e43cd3f95	testy: add a virtual clock helper for tests. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	b1d5548fa7	tailcfg: make NodeKey.IsZero have a value receiver	5 years ago
Brad Fitzpatrick	51b669e4bd	ipn: skip tailscaled UDP ports in service list	5 years ago
Brad Fitzpatrick	60ea635c6d	wgengine/magicsock: delete inaccurate comment I meant to include this in the earlier commit.	5 years ago
David Crawshaw	6ddbcab71e	logtail: rename the unused CheckLogs to DrainLogs Its semantics has changed slightly, this will let us use it to drive batched logging in special circumstances. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	51a12d1307	filch: a few minor comments Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	a184e05290	wgengine/magicsock: listen on udp6, use it for STUN, report endpoint More steps towards IPv6 transport. We now send it to tailcontrol, which ignores it. But it doesn't actually actually support IPv6 yet (outside of STUN). Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	073bb8de80	control/controlclient: don't use Node as value type	5 years ago
Brad Fitzpatrick	7caa288213	wgengine/magicsock: rename pconn field to pconn4, in prep for pconn6	5 years ago
Brad Fitzpatrick	5fa825f057	go.mod, go.sum: update	5 years ago
David Crawshaw	addbdce296	wgengine, ipn: include number of active DERPs in status Use this when making the ipn state transition from Starting to Running. This way a network of quiet nodes with no active handshaking will still transition to Active. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	1ad78ce698	magicsock: reconnect to home DERP on key change Typically the home DERP server is found and set on startup before magicsock's SetPrivateKey can be called, so no DERP connection is established. Make sure one is by kicking the home DERP tires in SetPrivateKey. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	455ba751d9	magicsock: start connection to HOME derp immediately The code as written intended to do this, but it repeated the comparison of derpNum and c.myDerp after c.myDerp had been updated, so it never executed. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	73cae4eb11	tailcfg, controlclient: standardize on wgcfg ShortString key printing Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago

Brad Fitzpatrick	19a1704abd	netcheck: use best DERP server in past 5 minutes to avoid flip-flopping Fixes #162	5 years ago
Brad Fitzpatrick	6de37f4cc0	tsweb: move some comments, add a TODO	5 years ago

David Anderson	3e2fadf872	version: add license header to input for generated file. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	98eceae55e	tsweb: add a Handler type. Handler is like http.Handler, but returns errors. ErrHandler converts back to an http.Handler, with added error handling and logging. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
